TECHNICAL FIELD

The following relates generally to wireless communications, and more particularly - to provide mobility management for the sleep mode among multiple mobile.

BACKGROUND ART

Wireless communication systems are widely deployed to provide various types of communication content such as voice content, data content, etc. Typical wireless communication systems may be multiple-access systems capable of supporting communication with multiple users by sharing the available system resources (eg, bandwidth, transmit power). Examples of such systems may include code division multiple access (CDMA), a multiple-access with time division (TDMA), multiple access, frequency division (FDMA), multiple access orthogonal frequency division multiplexing (OFDMA), etc.

Generally, a wireless multiple-access communication can simultaneously support communication for many mobile devices. Each mobile device may communicate with one or more base stations via transmissions on forward and reverse links. The forward link (or downlink) refers to the communication link from base stations to mobile devices, and the reverse link (or uplink) refers to the communication link from mobile devices to base stations. Further, communications between mobile devices and base stations may be established via single-input single-output (SISO), multiple-input systems and one output (MISO), systems with multiple input multiple output (MIMO), etc. .

One important aspect of mobile technology is the management of mutual interference between transmitters. A typical host cell is a cellular telephone, for example, uses a plurality of base stations with transceivers to communicate with user terminals within a cell. The zone of the base station typically (partially) overlap, so that a separate receiver frequently receives several overlapping signals at a given time. Accordingly, in such receivers as a result there is interference from a signal, potentially reducing the purity and quality of the communication signal cell, if left uncorrected.

There are many mechanisms for reducing intrasite interference. Some involve the use of MIMO-MISO- and transceivers that can tolerate higher levels of interference due to an improved analysis of the signals at the receiver. Latest modulation techniques such as orthogonal multicarrier modulation (e.g., as is used in Orthogonal Frequency Division [OFDM]), can effectively reduce the interference from the signals. In OFDM, orthogonal frequency subcarriers used to substantially reduce crosstalk between carrier signals. Another method includes querying reduce transmission power of the dominant interferer on one or more channel resources. If the transmission power of the source of interference is maintained within an acceptable range, the overlapping signals at the channel resources can often be tolerated in the receiver.

However, the mobile communication system in a state of constant change, as opening up new research and technologies. Architectural changes in the technology of mobile communication made to increase data rates, bandwidth, or to improve the transmission of data. The problem of interference must generally be reviewed for each new technology, to determine whether or not upset the balance provided by previous management arrangements interference. Thus, the control signal-hindrance is an ongoing challenge that requires new solutions, as implemented a new mobile communication technology.

DETAILED DESCRIPTION OF THE INVENTION

Below, various aspects are described with reference to the drawings, wherein like reference numerals are used to refer to like elements throughout. In the following description, for purposes of explanation, numerous specific details are set forth to provide a thorough understanding of one or more aspects. It may be evident that such aspects may be practiced without these specific details. In other instances, well-known structures and devices are shown in block diagram form in order to facilitate describing one or more aspects.

In addition, the following describes various aspects of the disclosure. It should be apparent that the foregoing ideas can thus be implemented in a wide variety of forms and that any specific structure and / or function disclosed herein is merely exemplary. Based on the ideas set forth in the document, one skilled in the art will appreciate that the aspect disclosed herein may be implemented independently of any other aspects and that two or more of these aspects may be combined in various ways. For example, the apparatus may be implemented and / or a method practiced using any number of the aspects set forth herein. Furthermore, the apparatus can be implemented and / or a method practiced using other structure and / or functionality in addition to one or more aspects set forth herein or other than those. As an example, many of the methods, mechanisms, systems and devices presented in the document are described in the context of determining the RUM accumulation rate for one or more sectors of a mobile network on the basis of the performance metric for a plurality of sectors. One skilled in the art should appreciate that similar techniques could apply to other communication environments.

The disclosure of the subject invention provides for the implementation of equal use of resources between sectors of mobile network (AN) access. Fairness can be based at least in part on the metric of the performance of one of the sectors of the mobile AN compared to the metric of the performance of another sector. In at least one aspect of the disclosed subject matter, the fairness of resource utilization can be realized by setting and / or adjustment of the interference avoidance credit accumulation (e.g., resource utilization message containing [RUM]) sectors to the mobile AN. Interference avoidance credit can be used to modify the interference between adjacent sectors of the wireless AN. In one example, the interference avoidance credit can be issued to a neighboring sector by querying the sector modify transmit power on a subset of wireless resources. Credit interference avoidance may indicate specific resources to reduce the noise level of a modified transmission power or a combination of both. In another example, the interference avoidance credit can result in modification of its own sector transmission power on a subset of wireless resources. Since the disturbance is usually caused due to the relative levels of the signal received at the receiver, the modification of its own power transmission sector may also affect the interference in the terminals served by sector. In addition to the foregoing, the interference avoidance credit reception can lead to the fact that the sector has not take any action (e.g., no modification or request to modify transmission power). Deciding on the type of action is most appropriate, be based on the metric of the performance of the neighboring sector, the metric of the performance sector, the aggregated metrics of the performance multiple sectors, problems observed in terminals load the sector, or the like, as discussed in the document.

One example is the interference avoidance credit RUM. RUM are messages issued on / via the wireless communication device to give directions to nearby transmitters to reduce their transmission power. Usually, decision making for issuing RUM based on the interference signal in a communication device, which occurs because of one or more interfering transmitters. Device receiving RUM, may reduce its transmit power by a predetermined factor, which should reduce the interference in the device issuing RUM. To implement fairness metric may be compared working characteristic plurality of sectors to determine whether one or more sectors at a disadvantage with respect to other sectors or a plurality of sectors. Collect, delivery and / or weighting of posts RUM or loans avoiding interference in general (including the modification of its own transmission power sector) can be adjusted to prevent RUM, issued by the adjacent sectors, excessive influence are at a disadvantage sector (eg, sector, having a relatively low operating characteristics of the metric) or impede sector with favorable conditions to store / to issue an excessive number of messages RUM.

It is understood that the wireless AN can use as a RUM reverse link (RL), and RUM forward link (FL) / downlink (DL). Post RUM FL / DL is RUM, transmitted from the base station to the wireless AN prevent AT. AT take RUM FL and determine whether to obey the RUM, as described in more detail below. When subordinate RUM, AT can reduce power on RL channels, reducing interference to the issuing base station (and, e.g., other base stations near AT). In contrast, the message RUM RL issued by the AT (for example, using RUM, gained serving sector related to AT) to one or more neighboring base stations wireless AN. The base station determines whether to obey RUM RL, and can reduce the transmission power of the FL, while subordinated RUM RL. As discussed below, the accumulation and / or adjustment of the intensities of the accumulation or extradition RUM may be applied to any of the messages RUM DL or FL, or to those, and others.

In a mobile environment, terminals (AT) and the access base stations increase the transmit power at different points in time based on various factors. For example, the base station can receive a signal from the AT to indicate that the base station transmitted signals are received at the AT with a very low power. Thus, the base station may increase the transmission power to improve the communication with the AT. Also in the cases when the transmission device has a poor performance in the receiver of the signal / noise (SNR), signal power can be improved. However, increased transmission power may be due to interference in nearby devices. Thus, RUM provides feedback to the device, indicating that the transmit power of the device is too high for other nearby devices.

However, the RUM may have drawbacks. For example, a single device can monopolize communication sector, giving the nearby device too much RUM. If other devices excessively reduce its transmit power based on the plurality of received RUM, the communication quality may suffer from such devices. Thus, accumulation and / or RUM issuance of messages to the device must be controlled so that some devices do not reduce the transmission quality of nearby devices. In essence, the principles of fairness can be introduced in place to ensure a satisfactory overall communication devices in a wireless AN.

In one aspect of the disclosure, a number RUM, which sector the wireless AN can deliver at a given time depends on the number of such RUM, which have been accumulated for a sector (e.g., sector associated with the 'access rights' RUM). The frequency with which the sector accumulates RUM, called intensity accumulation RUM. Accumulated RUM, associated with a sector, decrease (per unit), when the sector outputs RUM (e.g., on behalf of the base station or the mobile device in the sector). Thus, the intensity of accumulation RUM may, at least in part, control the frequency with which the sector can send messages RUM.

In at least one aspect of the disclosed subject matter RUM accumulation of messages is determined on the basis of cloning. The intensity with which the sector accumulates RUM message, the metric can be based on characteristics of the working sector in comparison with a similar metric operating characteristic of one or more neighboring sectors. RUM accumulation messages can be set is increased and / or decreased based on a comparison of the performance metrics of the sector. It is understood that the establishment and / or adjustment of the intensities of the accumulation of RUM, as described in the document can be applied to messages RUM FL or RL or both. In addition, metrics can be monitored operating characteristics over time to adjust / maintain RUM accumulation based on the simultaneous changes in the monitored metrics. Thus, the disclosure provides for the implementation of inter-sector fairness based on the operating characteristics of the various sectors of a mobile AN.

In at least one aspect, the accumulation metrics of the sector of the working characteristics can be obtained through the transport network between base stations. In another aspect, the metric may be accumulated on said base station shared by different base stations or organized in a centralized location (e.g., a central component of a radio access network [RAN], mobility component output of the network associated with each of the different base stations, or the like ). In accordance with additional aspects, one or more AT may perform accumulation metrics of the performance of base stations in a wireless AN and forward the accumulated metrics to a serving base station associated with the terminals AT. For example, AT can decode the messages over-the-air (OTA) metrics of the performance of the broadcast transmissions of nearby wireless base stations AN (e.g., where such broadcasts have adequate characteristics in SNR AT). An AT may then relay the information of the performance metric to a serving base station associated with the AT. Alternatively, in some aspects, AT may re-transmit and / or forward broadcast transmissions to the serving base station, which can decode the metrics of the performance of the repeated / forwarded signal.

In one or more other aspects, sector RUM accumulation rate determined based on the aggregate of the performance sector. For example, the base station wireless AN metrics can receive information concerning operating characteristics of neighbor base stations of base stations (e.g., the transport network) and / or from the AT, the serving base station a wireless AN. The collected information can be aggregated (combined) in the base station (or e.g. a wireless AN central controller in some cases) to ensure that the aggregate of the performance metric for a set of base stations of the wireless AN. Metric operating characteristic particular sector (or, for example, each sector of the wireless AN) may then be compared to the aggregate data to determine the degree of adverse conditions of the individual sectors in comparison with the aggregated data. The extent of adverse conditions, if any, can be used to install and / or update the RUM accumulation rate for the sector. For example, the RUM accumulation rate can be increased, decrease or maintain on the basis of the performance metrics of the sector compared to the aggregate data. By aggregating adjacent sectors in a single sector, may be established changes in the relative interference observed in a separate sector.

According to still another aspect, the rate at which the sector RUM provides messages or message RUM connects with existing AT in a sector may also be based on an aggregate of the performance metric. Thus, in the case where the sector has a low median data rate compared with the set of sectors RUM accumulation rate and / or intensity for issuing the sector can be improved. If subsequently the median speed of data transmission is improved with respect to aggregate sector data sector, the intensity of accumulation / delivery can be maintained or reduced, as is proper. Thus, the claimed invention provides a controlled accumulation and / or RUM issuance message based operating curve sector and further provides a mechanism for adjusting the operating characteristics of the sector by increasing / reducing the rate at which messages accumulate RUM in various sectors.

An exemplary metric operating characteristics may include the median data rate, average data rate, interference level, SNR, the ratio of a guaranteed bit rate to the median / average bit rate, the achieved delay packet transmission, achieved packet transfer delay than target with guaranteed delay or packet and / or the like, or a combination thereof. The metric (s) of the performance for the sector (306A, 306B) can be calculated and obtained from the base station 306A, 306B, serving sector (306A, 306B), or from a mobile device 304 is in communication with the base station 306A, 306B. These metrics (u) of the working characteristics may be forwarded to the data collection unit 308 through the communication line connecting the storage device RUM with base stations 306A, 306B, and / or a wireless link with the mobile device 304.

RUM accumulation apparatus 304 may further comprise a control unit 310 which sets the rate at which the device (304) within the sector (306A, 306B) accumulate RUM message. Fixed rate (s) accumulation RUM may be based on comparison of the metrics of the performance relating to the particular sector (for example, 306A), with a similar metric operating characteristic related to at least one additional sector (e.g., 306B), or an aggregated data metrics of the performance of a plurality of sectors. As a more specific example, the median data rate pertaining to sector A (306A), serving base station 306A, can be forwarded to the data collection unit 308. Furthermore, the median data rate pertaining to sector B (306B), served by the neighboring base station 306B, can be forwarded to the data collection unit 308. Intensity RUM accumulation for sector 306A and related devices (304) can be based at least in part on a comparison of the median data rate for the sector A, compared with the median value of the data rate for the sector B. According to some aspects, the intensity of accumulation RUM may be updated further based on such a comparison, for example, determined at periodic points in time, after detection of a change in the metric threshold (s) of the working characteristics of the respective sectors (306A, 306B) and / or the like, or combinations thereof.

Data accumulated block 308, data collection may be stored in a memory 312 (which, for example, may comprise any suitable form of electrical and / or magnetic storage medium such as a hard disk, optical disk, flash memory, random access memory and / or the like). Furthermore, the results conducted by the control module 310 of comparisons of the performance metrics may be stored in the memory 312 for reference. For example, when determining whether to update RUM accumulation rate set on the basis of changes in the metric (s) of the performance results intensity or precedes (and) RUM accumulation can be obtained from the memory 312. The RUM accumulation apparatus 302 further comprises a processor 314 configured with to execute commands on the data stored in the memory 312 related to the process, relevant device 302 accumulation RUM (e.g., the accumulation and storage of data in the memory, the analysis of the metric in respect sector comparing metrics for one sector with respect to one or more other sectors , determining intensities RUM accumulation based on such comparisons, updates intensities RUM accumulation, and so on).

It is appreciated that may include any number of base stations 306A, 306B to the network (RAN) 306, radio access system 300. Base stations 306A, 306B may include various wireless transmitters, including mobile transceivers, transmitters standard (WiFi) wireless interoperability , microwave transmitters (e.g., standard [WiMAX] global compatibility of communication devices to access the microwave range) and / or the like associated with the node 306 conventional wireless mobile RAN. Thus, various cellular, mobile communications and the like access technologies can be incorporated into a mobile node 306 RAN.

4 illustrates a block diagram of an exemplary control device 402 RUM according to one or more aspects of the disclosed subject matter. The apparatus 402 can be integrated with centralized controller RAN (e.g., see. The system controller 130 of Figure 1 above) or may be distributed across one or more of the base stations in RAN (e.g., base stations 306A, 306B of Figure 3, above, or transport network 506 of Figure 5, below). The device 402 can obtain metrics of the performance of a wireless communication offered by these base stations, and aggregate data to determine and update the RUM accumulation rate sector by sector metrics, compared to the aggregated data metrics. Accordingly, the system 400 provides a methodology based on fairness accumulation RUM, which can determine the desired metric connection and optimize RAN general action based on changes in the levels of metrics connection.

RUM management apparatus 402 may comprise storage device 406, which receives data via communication interface 404 to components of RAN (e.g., base stations). The apparatus 406 storage comprises a block 410 of data collection, which receives the data metrics of the performance relating to the sectors RAN, and unit 412 control which determines the intensity of accumulation RUM for sectors RAN by comparing metrics of the performance sector metric operating characteristic of at least one other sector. Thus, the device 402 may provide fairness based on sector RUM accumulation rate based on the desired metrics related to wireless communications. Thus, the sector is the poor metrics may be given a higher rate of accumulation of RUM, which has the consequence of increasing the number of RUM, issued on the devices in the sector with poor performance. Sector are relatively strong metrics, can be given a lower rate of accumulation of RUM, a consequence of having fewer RUM, issued to devices strongest sectors. Thus, by having more RUM, sectors with the lowest metric can more quickly reduce the transmission power of neighboring interfering transmitters. Similarly, sectors with strong metrics have less ability to reduce the transmission power of the adjacent transmitters. This scheme provides significant benefits. First, the devices most in need to reduce unwanted power transmission, provide greater opportunity to do so. Then, the devices that have less need to reduce the power of interfering transmissions are less able to do so. Where a weak sector coexists with a strong sector, essentially, that the weak sector will be able to reduce the transmission power of the neighboring sector, while avoiding a significant reduction in the power of its own signal by RUM, issued a strong sector.

RUM management apparatus 402 can further comprise a RUM control 408. The device 408 can be installed to control the intensity of the device for delivery of accumulated RUM-based metrics intersectoral performance. Additionally, the device 408 can control the intensity of regulation RUM accumulation based on the changing of the performance metrics of the sector; accumulation rate may be updated based on the changing difference in the metric (s) operating curve sector compared with metrics of neighboring sectors.

The device 408 may include a control module 420 implementation that sets the rate at which the device can produce sector accumulated RUM. The intensity of the issuance may be determined in addition to the intensive accumulation of defined storage device 406 RUM. Thus, the device may accumulate in time series RUM, but may be limited in how quickly it can use the RUM. Consequently, if the metric is operating characteristics for the device suddenly changes considerably worse, the device's ability to issue many accumulated RUM in a short period of time, which can significantly degrade the overall performance of nearby devices may be modulated at least by the plurality RUM, accumulated for sector serving device. At least one other aspect, RUM issuance can be further limited by the maximum intensity RUM issuance. In a further aspect, RUM issuance rate may depend on the degree of adverse conditions for the sector. In at least one aspect, RUM issuance can be modulated according to a combination of the preceding, or similar mechanisms.

As discussed above, the intensity of the issuance of RUM may be predetermined intensity and / or sector-specific intensity, established on the basis of comparisons of metrics of performance, similar to those defined by the control module 412 to determine the intensities of accumulation (for example, that set the level of adverse conditions for the sector in comparison with other sectors). In one or more aspects, the intensity is modulated in accordance with the issuance of the associated intensity of accumulation RUM (eg, messages RUM unit weight, or in other aspects, modulation may include weights suspended RUM) for the sector, the service unit. In such aspects, the implementation module 420 may optionally determine whether the next RUM sending terminal located in the sector based on the RUM accumulation rate, RUM issuance rate, comparing the metrics of the performance, the adverse conditions of the sector or a combination of these and / or similar factors.

The apparatus 408 may further comprise a control unit 418 adjusting the priority that can update RUM accumulation rate sectors RAN. Updates intensities may be based, at least in part, on the current metric comparisons of the performance for such sectors as compared with one or more neighboring sectors. The following example is presented to illustrate one aspect, which can be determined by the intensity of accumulation RUM; however, it should not be construed as restrictive. Preferably, other mechanisms for updating intensities accumulation RUM, based on the metrics of the performance of the set of sectors in the RAN, known to those skilled in the art or made known to one skilled in the art by providing a document context including the document as part of the disclosure of the subject invention.

For purposes of the following examples are defined the following quantities:

mi (k) = median value of the performance metric terminals AT sector i at time k;

ri (k) = RUM accumulation rate in sector i in period k;

Mi (k) = median for mj (k) j, which are neighbors of i, including i.

<IMG>

At the end of the period (k) to adapt the intensity of RUM (e.g., time interval, after which the module 418 adjusting the priority determines the updated intensity RUM) sector may update ri for the period (k + 1) (or, for example, leave ri is substantially constant, wherein applicable). Ri updated is stored in the memory 416 and processor 414 may be used during the period (k + 1) to generate a modified message RUM intensity value. Adapting the RUM accumulation rate can be based on the criteria of fairness, using a comparison of the performance sector are compared with the aggregate data of the performance of one or all of the remaining sectors j, i including the sector, at least in some embodiments. The following algorithms provide one mechanism to update ri on the basis of inter-sector fairness:

if mi (k) <Mi (k), the ri (k + 1) = ri (k) + Δ + i (k) (where Δ + i (k) is a positive value);

if mi (k) ≥Mi (k), the ri (k + 1) = ri (k) -Δ- i (k) (where Δ- i (k) is a positive value).

Thus, in a case where a median value of the metric of the performance (e.g. data rate) for the sector mi (k) is less than the median value of the metric of the performance for a plurality of sectors Mi (k) (e.g., all sectors j, including the sector i), the intensity of ri RUM accumulation sector i may be increased to a positive value. In contrast, in a case where a median value of the performance metric for the sector i is less than or equal to the median value of the performance metric for a plurality of sectors RUM accumulation rate for the sector i may be reduced to a positive value. In addition to the above, the intensity of accumulation RUM may be limited to the maximum and / or minimum intensity of accumulation. It can be determined the maximum intensity to prevent being in unfavorable conditions worsen the sector over the neighboring sectors. The minimum intensity, on the other hand, enables the sector to serve multiple users observing excessive interference, even if the sector as a whole is not at a disadvantage with respect to the neighboring sectors. In addition, the minimum and maximum intensities of the accumulation can be determined based on the degree of unfavorable conditions of the sector as compared to adjacent sectors as described herein.

According to one or more additional aspects of the disclosed subject matter, the priority adjustment module 418 can update RUM accumulation rate for the sector constant value or a variable value. The constant value can be determined in advance based on the various parameters of the mobile radio node RAN (e.g., interference, scattering, multipath). It should be appreciated that the radio parameter can be updated at different time points and used to modify a constant value. The variable may be based on various factors present during one or more periods close in time to a specific period (for example, may be used status indicators for a period of k, aggregated state indicators for a period of k and / or one or more prior periods k -2, k-1 or the like). Various parameters may include operating characteristic metric for a sector or one or more neighboring sectors, various radio parameters discussed above with respect to a constant value, or a combination thereof or the like. Accordingly, the intensity of the RUM accumulation can be adjusted by changing the value. As an example, if a sector is significantly worse than its neighboring sectors corresponding RUM accumulation rate can be increased at a relatively large value.

According to one or more other aspects RUM management apparatus 402 can further comprise a module 422 (reference) and the priority analyzer 424 request. The module 422 may set the priority weighting for RUM, issued devices located within the sector. The weighting factor can be based at least partially on the current RUM accumulation rate for the sector. The weighting factor can be used by receiving transmitters to determine whether to follow or ignore the RUM (eg, based on the metric (s) of the performance-related sectors receiving transmitters). RUM request parser 424 may use the RUM accumulation rate for the priority RUM, take specific transmitter (eg, base station, AT). The priority RUM may be based, at least in part, on the intensity of accumulation RUM transmitter to the receiver, similar weighting factor RUM, discussed above. Thus, the analyzer 424 can request RUM based on the priority to determine whether the transceiver to comply with or ignore the RUM.

5 shows a block diagram of a system 500 that provides RUM management for a mobile AN according to aspects disclosed herein. System 500 can comprise a mobile device 502 associated with base stations 506A, 506B, 506C, 506D RAN. In addition, the base stations are connected to the transport network 506, whereby the base station can exchange data. RUM accumulation device 508 is connected with the transport network. In one aspect, the determined data of the performance metrics for different sectors and shared RAN base stations 506A, 506B, 506C, 506D via the transport network 506. In another aspect, the data of the performance metrics for different sectors may be downloaded over the network to the device 508 RUM accumulation of the base stations 506A, 506B, 506C, 506D. According to still further aspects of the performance metric may be determined based on the OTA message, received at a mobile device 502 within the sectors. Mobile devices can analyze OTA messages, to determine the metrics of the performance with respect to these messages. These metrics may then be delivered to the RAN, and the base stations 506A, 506B, 506C, 506D and / or RUM accumulation apparatus 508 through such base stations 506A, 506B, 506C, 506D.

The device 508 can detect the accumulation of RUM RUM accumulation rate for sectors (506A, 506B, 506C, 506D) in the RAN and distribute RUM these sectors for the use of devices such sectors. In another aspect, the RUM accumulation rate for each sector may be determined by base stations 506A, 506B, 506C, 506D, associated with these sectors. Accumulated RUM can be distributed to mobile devices 502 as soon accumulated.

Control module 504 RUM, associated with the mobile device 502 may modulate the intensity with which the RUM issued to other devices in the adjacent sectors (506A, 506B, 506C, 506D). The intensity of the issuance of the mobile device 502 can specify how often the device 502 can send the accumulated RUM. The intensities of issue can be determined on the basis of the performance metrics of wireless transmissions in sectors defined as described above. In addition, the RUM accumulation rate and / or RUM issuance rate can be updated based on changes in the metrics as described herein. Accordingly, system 500 provides a fairness-based mechanism for storing messages and RUM RUM issuance, utilizing the characteristic performance metric sector as compared with one or more neighboring sectors.

6 illustrates a block diagram of a system 600 comprising an exemplary base station 602 that provides RUM accumulation management based on the characteristic performance metrics of sectors in RAN. In at least one aspect of the disclosed subject matter, the base station 602 may determine the metric based on the operating characteristics of wireless transmission, sector specific RAN. Moreover, base station 602 may provide the functions of personal communications for the mobile communications network with respect to mobile devices 604 located within the geographic area serviced by the network (e.g., see FIG. 1 and 2). The base station 602 may continue to broadcast signals personal communications until the target response received by the mobile device will not be accepted by the mobile network termination command personal communication, timer expires validity supported by the base station 602 or (not completed) a combination thereof. According to particular aspects, base station 602 may support the counter register for the mobile device with respect to the tracking area / location, the serving base station 602. In addition, the counter register can be maintained, even if the mobile device is unable to respond to the event in a personal communication. Accordingly, system 600 facilitates inter-system mobility by means of personal communications devices 604 independently of the other systems (not shown) and maintaining registration device despite unsuccessful answer personal communication (e.g., when the mobile device responds to a page of another system).

Base station 602 (e.g., access point, ...) can comprise a receiver 610 that receives signal (s) from one or more mobile devices 604 through a plurality of receive antennas 606, and a transmitter 632 that transmits signals to one or more mobile devices 604 through transmit antenna (s) 608. Receiver 610 can receive information from receive antennas 606 and can further comprise a signal receiver (not shown) that receives uplink data transmitted by mobile device (s) 604. Additionally, receiver 610 is capable of interacting associated with a demodulator 612 that demodulates received information. Demodulated symbols are analyzed by a processor 614, which also provides symbols to a modulator 630 for transmission. Processor 614 is coupled to a memory 616 that stores information related to functions provided by base station 602. In one instance, stored information can comprise protocols for preparation and / or determination of the performance metrics of wireless communications with mobile devices 604. Specifically, the stored information may include rules for determining or updating RUM accumulation intensities, and intensities RUM issuance of such devices 604, depending on the metrics of the performance compared with similar metrics relating to the neighbor base station (s).

Processor 614 is further coupled with a data acquisition unit that can acquire information of the performance metrics relating to the base station 602 and at least one neighboring base station (not shown). Information stored in the data acquisition unit 618 may be stored in memory 616 for access by other components (612, 614, 620, 622, 624, 626, 628, 630) of the base station 602. The control unit 620 may set the rate at which mobile devices 604 within a sector served by base station 602 (and, for example, communicatively connected to it), messages accumulate RUM. The intensity may be based on the accumulation of comparison of the performance metrics associated with the base station 602, compared to at least one other of the neighboring base stations, as described herein. Intensity values ​​can be stored in the accumulation memory 616, subject to access by other components (612, 614, 620, 622, 624, 626, 628, 630) of the base station 602.

Priority adjustment module 622 can update RUM accumulation rate on the basis of the performance metrics of subsequent transmissions of the base station 602. Thus, if the median data rates for devices 604 associated with base station 602 decreases as compared with the median values ​​of the data rate for the neighbor sectors, correction module 602 may increase the priority RUM accumulation rate for such devices 604. It will be appreciated that the foregoing example represents only one mechanism for updating the intensity of accumulation and the disclosure of the subject invention should not be construed in such a limited example. Preferably, the other examples presented herein, the examples, known to one skilled in the art or made known to one skilled in the art represented by the document context included in the disclosure of the subject invention.

In addition to the foregoing, the implementation module 624 can determine the rate at which the device 604 can send or extradite accumulated RUM. Dispensing intensity can be set on various factors, including the RUM accumulation rate for the sector, the number of devices 604 operating within the sector, one or more of the performance metrics of the sector, or a combination thereof or the like. In some aspects, the implementation module 624 may modulate the intensity with which the device 604 posts RUM issued, depending on the intensity with which the sector accumulates RUM (e.g., where modulation may comprise RUM weight or may have a unit weight). At least, in another aspect, the implementation module 624 based at least in part, RUM accumulation rate and / or intensity of dispensing RUM may determine whether the next RUM sending terminal, located within a sector served by base station 602.

Base station 602 may further comprise a RUM request parser 626, which determines the priority RUM, the mobile device 604 received from the adjacent sectors. Priority may be based on the RUM accumulation rate and the corresponding intensity and / or the characteristic performance metric for another sector. Moreover, base station 602 can comprise a priority module 628 that is based, at least partially, corrects the RUM accumulation rate RUM weight, issued sent or devices 604 in the sector. Accordingly, neighboring devices that receive RUM, may determine whether to comply RUM issued, based at least in part by weight. Optionally, in the case where a single RUM weight, it must be observed by all such neighboring devices.

7 illustrates a block diagram of an example system 700 that comprises a mobile device 702. Mobile device 702 may be configured with the ability to communicate wirelessly with one or more base stations 704 and associated (subsidiary) networks for mobile communications (not shown) . Mobile device 702 may further be configured to acquire metrics of the performance of nearby base stations and transmit the metrics to a serving base station 704 as described herein.

Mobile device 702 includes at least one antenna 706 (e.g., a receiver (accumulator) transmission or group of such receivers comprising an input interface) that receives a signal (e.g., signal, such as OTA message) and receiver ( ) 708, which performs typical actions (e.g., filters, amplifies, downconverts, etc.) the received signal. According to at least some aspects, processor (s) 712 can analyze signals received from demodulator (s) 710 and receive metric characteristics for such radio signals. In general, antenna 706 and transmitter 726 (collectively referred to as a transceiver) can be configured to facilitate wireless data exchange with base station (s) 704.

Antenna 706 and receiver (s) 708 can also be coupled with a demodulator (s) 710 that can demodulate received symbols and to supply them to the processor (s) 712 for evaluation. In some aspects, the receiver 708 can receive OTA transmissions from base stations (704). In a specific example, the receiver 708 can receive OTA transmissions from a neighboring base station (e.g., as part of a broadcast signal from a base station), comprising the metric of the performance of the neighbor base station. OTA message can be analyzed in the mobile device 702 and / or forwarded to the base station 704 for analysis. In addition, the receiver 708 may receive the second OTA message from the neighboring base station, RUM contains a requirement that the mobile device 702 has reduced the power of the transmitter 726.

It should be appreciated that processor (s) 712 can control and / or access one or more components (706, 708, 710, 714, 716, 724, 726) of the mobile device 702. Further, processor (s) 712 can execute one or more modules, applications, arrangements or the like (716, 718, 720, 722) containing information or feedback control (adjustment) relating to the execution of functions of the mobile-phone handset 702. For example, such functions can include management of a wireless communication with the remote devices (704), receiving OTA messages, the analysis of such communications, the definition of performance metrics for wireless radio transmission, reception and processing of RUM or the like, as described in the document.

Mobile-telephone handset 702 can additionally include memory 714, which is connected with the possibility of interaction with the processor (s) 712. The memory 714 can store data to be transmitted, the reception and the like, and instructions useful for conducting wireless communication with the remote means (704). Further, memory 716 can store the modules, applications, arrangements, etc. (718, 720, 722) executable aforementioned processor (s) 714.

In some aspects of the disclosure, mobile device 702 may comprise analysis unit 716 which determines the operating characteristic metrics (e.g., mean or median data rate, interference, SNR, etc.) of wireless signals received at the mobile device 702. Also , the routing module 718 may wirelessly transmit the metrics of the performance of one or more OTA messages received at the receiver 708, the base station 704 serving the mobile device 702. Based at least in part, of the performance metric values, the serving base station 702 may be sent to the mobile device 704 a message that includes a RUM. RUM may be issued to the mobile device 702 to use such a device 702 in the transmitter power control nearby or may be similar to such messages sent to the mobile device 702 to reduce the power of the transmitter 726.

According to particular aspects of the disclosure, the mobile device 702 can comprise a priority module 720 that identifies and processes the weighting factor for a received RUM. In addition, priority module 720 may determine a weighting factor for the RUM, issued for use by the mobile device 702. In either case, the weighting may be determined, at least in part, according RUM accumulation rate, related to the sector serving the mobile device 702. The component 722 Arbitration may give instructions to the processor 712 observe DL RUM (e.g., relating to the data RL, transmitted by the mobile device 702) based on the comparison DL RUM weight and the characteristic performance metric for the sector. Stored in the memory arbitration rules 714 may determine when it is necessary to observe the DL RUM, based on this comparison.

The aforementioned systems have been described with respect to interaction between several components, modules and / or communication interfaces. It will be appreciated that such systems and components / modules / interfaces can include those components or sub-components specified therein, some of the specified components or sub-components, and / or additional components. For example, the system may include a RUM accumulation apparatus 302, control device 408 and the RUM RUM management module 504 or a different combination of these and other components. Subcomponents can also be implemented as components communicatively coupled preferably with other components rather than included in the parental (core) components. Additionally, it should be noted that one or more components may be combined into a single component providing aggregate functionality. For example, data collection unit 308 may include a memory device 312, or vice versa, by a single component to facilitate the admission of the performance metrics of wireless communications, and storing the received information of the metric. The components can also interact with one or more other components not specifically described herein but known to those skilled in the art.

Taking into account the above-described exemplary systems and methods that may be implemented in accordance with the disclosed subject matter will be better appreciated with reference to the flow chart in Figures 8-10. Although the purpose of simplicity of explanation, the methods are shown and described as a series of steps, it should be appreciated that the claimed subject matter is not limited to the next stage, as some blocks may occur in different orders and / or concurrently with other blocks from those which are illustrated and described in document. Furthermore, there may be required not all illustrated steps to implement the methods described below. Furthermore, it should be further appreciated that the techniques disclosed below and throughout this specification, can be stored on the product to facilitate transporting and transferring of such methodologies to computers. The term "product" is used to encompass a computer program accessible from any computer-readable device, device in conjunction with a carrier, or storage medium.

8 shows a flowchart of an exemplary method 800 that provides inter-sector fairness for reducing interference in a mobile communication. In step 802, method 800 can obtain the characteristic performance metric for at least two mobile base stations. The metric of the performance can be related to the quality of the wireless communication pertaining to two mobile base stations. As specific examples of the performance metrics may include the median data rate, average data rate, signal interference, SNR, a percentage of a guaranteed bit rate, or a similar metric of wireless signals, or a combination thereof.

In one or more aspects, at least two mobile base stations may be neighboring base stations of the mobile RAN site. In this case, wireless transmission base stations can often interfere with each other at the receiver. Metrics such characteristic signals can be determined in the receiving device and transmitted back to the base station. In another aspect, the metric characteristics can be obtained on the basis of the uplink signals received at the base stations from the wireless devices (e.g., the metric can be specified as part of the uplink signals, or can be analyzed directly uplink signals to determine the metric specifications such signals). Information of the performance metrics can be used with the base stations, aggregated in the general control device and / or a shared mobile device for further analysis.

In step 804, the method 800 may determine the RUM accumulation rate for the devices within the sector the mobile node RAN. The intensity may be based at least in part, on a comparison of the performance metrics of the at least two base stations. As a specific example to illustrate the foregoing, the average data rate for the sector can be compared with the average rate of data transmission for the neighboring sector (s). The intensity of the RUM accumulation can then be set on the basis of this comparison. In one particular aspect of the performance metrics data for all the sectors may be accumulated to form the aggregate data of the performance metrics of the sector. Intensity RUM accumulation for each sector may be based on a comparison of the performance metric for each sector aggregated data of the performance metric. Accordingly, the method 800 provides an algorithm to establish the RUM accumulation based on the operating characteristics of wireless interactions between sectors mobile node RAN. Through this algorithm can be reduced the likelihood that the performance of the sector improved by bad working sector, providing increased reliability for mobile communication.

9 illustrates a flowchart of an exemplary method 900 that can manage RUM accumulation intensities sectors RAN mobile node, to provide inter-sector fairness for the node. In step 902, method 900 can obtain a metric of performance, at least with respect to the two mobile base stations. In step 904, method 900 may determine the RUM accumulation rate for sectors of the mobile RAN site, served by each station, at least two base stations. In step 906, method 900 can determine the intensity RUM issuance device each sector, based at least in part, RUM accumulation rate. Thus, the frequency with which a particular device (or, for example, a plurality of devices) can generate a RUM, can be determined using the intensity of accumulation. Other factors that determine the intensity of issue could include the number of devices in a sector associated with a particular device metrics in performance compared to other devices sector, the type of call that involves a particular device (for example, calls with the highest quality of service may be given a higher intensity issuing to maintain the operating characteristics of such call, the call of low quality of service may be given a lower intensity value issue, because the quality is not so large relative effect, and so on), or the like, or a combination thereof.

In step 908, method 900 can receive a change in the metrics of the performance. For example, the metrics of the performance can be re-evaluated at a later time. As a specific example, the metrics of the performance can be re-evaluated periodically. Current metrics of the performance (or, for example, changes in current metrics compared with previous metrics) can be used to recalculate the RUM accumulation rate. In step 910, method 900 can update the sectors for the intensity of accumulation of the mobile RAN node based on a comparison of the performance metric of the sector to the aggregated operating curve sector. Thus, if the metric is below the sector of the working characteristics of the performance metrics are aggregated (or, for example, less aggregated metrics of the performance on the threshold), the RUM accumulation rate of the sector can be improved. Where the characteristic performance metric sector larger aggregated metrics of the performance (or, for example, greater than the sum of the performance metric plus a threshold value) RUM accumulation rate for the sector can be reduced. Where metric sector operating characteristics substantially equivalent to the aggregate of the performance metric, RUM accumulation rate can be increased, decreased or left unchanged. In addition to the foregoing, the changes in the metric of the performance sector can be based on a constant value (for example, determined on the basis of previous intensive accumulation RUM, radio conditions node RAN mobility, time-averaged statistics node RAN mobility or the like) or on the basis of a variable defined at least partially according RUM accumulation rate, the difference in operating characteristic metric for the sector relative to at least one neighbor sector (e.g., sector total working characteristics) or the like, or combinations thereof.

In step 912, method 900 may set the priority of the sector on the basis of the intensity of accumulation. Priority sectors can be used to determine whether the rate of accumulation of RUM, accepted the device sector, observed by the receiver. Priority can be based at least partially on the RUM accumulation rate for the sector. Alternatively or in addition, the priority can be based on the weighting coefficient of the received RUM. In step 914, the method 900 may set the weight coefficient for the RUM, outputted by the sector based at least in part, of the performance metric or sector RUM accumulation rate. In step 916 the device is instructed to observe the RUM based on priority sector RUM weight or both.

10 illustrates a flowchart of an exemplary method 1000 that facilitates inter-sector fairness for the mobile node RAN. At 1002, method 1000 can obtain a metric of the performance of the base station of OTA transmission originating from a base station. At 1004, method 1000 can forward metric working characteristics to the serving base station. At 1006, method 1000 can receive RUM based at least in part, of the performance metric. In step 1008, method 1000 can observe RUM based on the weight RUM, the characteristic performance metric for the serving sector, or both. Compliance RUM may further comprise the step of reducing power wireless transmission. At 1010, method 1000 can analyze the operating characteristics of the metric for the sector of the serving sector. Analysis can refer to the received from the serving base station OTA message. In step 1012, method 1000 can store messages RUM based at least in part on the metric of the performance sector, compared to the aggregated metric operating curve sector, the aggregate metric operating characteristic sector comprises, at least, information related to the base station.

11 is a block diagram of an example system 1100 that can facilitate wireless communication according to some aspects disclosed herein. On the downlink, at access point 1105, the CPU 1110 transmit data (TX) receives, formats, codes, interleaves and modulates (or symbol maps) traffic data and provides modulation symbols ("data symbols"). Symbol modulator 1115 receives and processes the data symbols and pilot symbols and provides a stream of symbols. Symbol modulator 1120 multiplexes data and pilot symbols and provides them to a transmitter unit 1120 (TMTR). Each transmit symbol may be a data symbol, a pilot symbol or a signal value of zero. The pilot symbols may be sent continuously in each symbol period. The pilot symbols can be frequency division multiplexed (FDM), multiplexed with the orthogonal frequency division multiplexing (OFDM), time division multiplexed channels (TDM), code division multiplexed (CDM) or a suitable combination thereof or the like modulation and / or transmission .

TMTR 1120 receives and converts the stream of symbols into one or more analog signals, and further to the operating state (e.g., amplifies, filters, and upconverts) the analog signals to generate a downlink signal suitable for transmission over the wireless channel. The downlink signal is then transmitted through an antenna 1125 to the terminals. At terminal 1130, an antenna 1135 receives the downlink signal and provides a received signal to a receiver unit 1140 (RCVR). Receiver unit 1140 drives the operating state (e.g., filters, amplifies, and converts to a decrease in frequency) the received signal and digitizes the operation signal to obtain samples. Symbol demodulator 1145 demodulates the received pilot symbols and provides them to a processor 1150 for channel estimation. Demodulator 1145 symbols further receives from processor 1150 frequency response estimate regarding downlink performs data demodulation on the data received symbols to obtain data symbol estimates (which are estimates of the transmitted data symbols), and provides the data symbol estimates to processor 1155 data RX (reception ), which demodulates (i.e., symbol maps back), deinterleaves, and decodes the data symbol estimates to recover the transmitted traffic data. The processing by symbol demodulator 1145 and RX data processor 1155 are complementary to the processing by symbol modulator 1115 and TX data processor 1110, respectively, at access point 1105.

On the uplink, TX data processor 1160 processes traffic data and provides data symbols. Symbol modulator 1165 receives and multiplexes the data symbols with pilot symbols, performs modulation and provides a stream of symbols. Transmitter unit 1170 then receives and processes the stream of symbols to generate an uplink signal, which is transmitted by the antenna 1135 to the access point 1105. Specifically, the uplink signal may comply SC-FDMA (Single Frequency FDMA) and may include the transition frequency hopping mechanisms as described herein.

At access point 1105, the uplink signal from terminal 1130 is received by antenna 1125 and processed by a receiver unit 1175 to obtain samples. Symbol demodulator 1180 then processes the samples and provides received pilot symbols and data symbol estimates for the uplink. RX data processor 1185 processes the data symbol estimates to recover the traffic data transmitted by terminal 1130. A processor 1190 performs yaet channel estimation for each active terminal transmitting on the uplink. Multiple terminals may transmit pilot concurrently on the uplink on their respective assigned sets of pilot subbands, where the pilot subband sets may be interleaved signals.

Processors 1190 and 1150 direct (e.g., control, coordinate, arrange, etc.) operation at access point 1105 and terminal 1130, respectively. Respective processors 1190 and 1150 can be associated with memory units (not shown) that store program codes and data. Processors 1190 and 1150 can also perform computations to derive frequency estimates of the impulse response for the uplink and downlink, respectively.

For a multiple-access system (e.g., SC-FDMA, FDMA, OFDMA, CDMA, TDMA, etc.), multiple terminals can transmit concurrently on the uplink. For such a system, pilot subbands may be shared among different terminals. The channel estimation techniques may be used in cases where the pilot subbands for each terminal span the entire operating band (possibly except for the band edges). This structure pilot subbands would be desirable to obtain frequency diversity for each terminal. The methods described herein may be implemented by various means. For example, these techniques may be implemented in hardware, software, or a combination thereof. For a hardware implementation, which can be digital, analog, or both digital and analog, the processing units used for channel estimation may be implemented within one or more application specific integrated circuits (ASIC), digital signal processors (DSP), devices digital signal processing (DSPD), programmable logic devices (PLD), field programmable gate arrays (FPGA), processors, controllers, microcontrollers, microprocessors, other electronic units designed to perform the functions described herein, or a combination thereof. When implemented in software, the execution may be through modules (e.g., procedures, functions, and so on) that perform the functions described herein. The software codes may be stored in memory units and executed by processors 1190 and 1150.

12 and 13 depict block diagrams of example systems 1200, 1300 that provide and / or facilitate the RUM accumulation based on metrics of the performance in the sector of the mobile AN. System 1200 includes a module 1202 to obtain the characteristic performance metric for the sector of the mobile RAN site. Module 1202 can further derive an operating characteristic metric, at least one neighbor sector. In at least one aspect of the performance metrics may be combined into a single aggregated metric wireless mobile node RAN. System 1200 can further comprise a module 1204 which sets the rate at which the devices in the sector RUM accumulate. Module 1204 may determine the intensity of the at least partially on a comparison of the performance evaluation and evaluation of the sector (c) of the performance of neighbor sectors (a). In one specific aspect, module 1204 can establish the intensity on the basis of evaluation of the performance for the sector and the total evaluation of the performance of sectors to the mobile RAN site.

System 1300 can comprise a module 1302 for receiving wireless OTA messages. The module can obtain the first OTA message that contains the metric of the performance for the sector of the mobile AN. The module 1302 may then receive the second OTA message that contains RUM. The first OTA message and / or the second OTA message and information related thereto, can be maintained in the data storage unit 1306. In addition to the foregoing, system 1300 can comprise a module 1304 for forwarding dedicated OTA message to a serving base station. The module 1304 may send to the serving base station, e.g., the first OTA message, or at least the metric of performance. In one particular aspect, the first response to the OTA message from the serving base station can determine whether the RUM observed system 1300. Such determination module 1308 may be designed to execute processing instructions, wherein such instructions based at least in part on the metric Working characteristics sector weighting coefficient RUM or a combination.
