Paging user devices in a wireless access network

TECHNICAL FIELD The invention relates generally to wireless communication, and more particularly to the design of a wireless signal header to help reduce interference in semi-planned or unplanned wireless access networks.

II. Prior art [0002] WO 2007/066975 discloses a method of adaptive discontinuous reception based on an extended paging indicator to improve the energy-saving efficiency of a terminal in asynchronous code division multiple-access systems. "

[0003] Wireless communication systems are widely used to provide various types of communication content, e.g. voice content, data content, etc. Typical wireless communication systems can be multiple-access systems that allow communication with multiple users by sharing available system resources (e.g., bandwidth). , transmission power). Examples of such multiple access systems may include code division multiple access (CDMA) systems, time division multiple access systems (TDMA), multi-split frequency division systems (FDMA), orthogonal frequency division multiple access (OFDMA) systems and the like .

[0004] In general, a wireless multi-access communication system can simultaneously support a connection for multiple mobile devices. Each mobile device may communicate with one or more base stations through transmissions on forward and reverse links. The forward link (or downlink) refers to the communication link from the base stations to the mobile devices, and the reverse link (or link up) refers to the communication link from the mobile devices to the base stations. In addition, communication between mobile devices and base stations can be made using systems with one input, one output (SISO), multiple inputs, one output (MISO), multiple inputs, multiple outputs (MIMO), etc.

[0005] One of the functions of the mobile network technology, which favors the comfortable mobility of devices, is the idle / active mode of mobile devices. The mobile device, when it is active, the mobile device can process incoming signals, transmit response signals and facilitate remote voice and / or data communication with other devices. Such activity may consume a significant amount of energy and thus reduce the battery life of the mobile device. Fortunately, a typical user only periodically uses active communication through the device. Thus, significant power can be maintained by not processing the received wireless signals during the unused period. Periods of limited processing or non-processing are referred to as idle periods.

[0006] In order to receive an incoming call (inbound communication), it is required that the mobile device (eg when another user calls the mobile device) processes signals indicating that such a connection is waiting for the mobile device. However, if the device processes a few or does not process any signals during inactivity, it will not notice this connection if it is not activated long enough to process these signals. To facilitate active / idle mobility, the base station supporting the mobile device coordinates the periods in which

The mobile device activates the processing of incoming signals. These periods can be short and relatively rare to reduce the average processing of mobile devices and energy consumption in idle mode. When the incoming call for the mobile device is received at the base station, the paging signal is scheduled and transmitted in one or more coordinated periods of time through which the mobile device monitors (e.g., starts and processes signals). Thanks to the coordination of interrupted periods of active signal processing, the mobile device can identify and receive an incoming call, while maintaining significant computing power and battery life. This arrangement provides significant savings for the average user of the mobile device,

SUMMARY OF THE INVENTION [0007] The subject of the invention is defined by the appended claims. The following is a simplified summary of the nature of one or more characters to provide a basic understanding of these characters. This abstract of the creature is not a comprehensive discussion of all the characters under consideration and neither aims to identify key or critical elements for all characters, nor to determine the scope of any or all of its characters. Its purpose is to present concepts for one or more characters in a simplified form as a prelude to more a detailed description that was presented later.

[0008] Within the framework of the present invention, it is envisaged to establish a paging control for mobile devices connected to a wireless access network (AN) with orthogonal frequency division multiple access (OFDMA). Establishing paging control may involve segmentation of the wireless signal over a number of time frames determined from an integer raised to a solid power (e.g.^ΛΚ, where K is a constant). In addition, paging events can be scheduled for part of the wireless signal time frames. The selection of time frames for paging events may be based on a formula that uses an integer raised to a constant power that is a function of a fixed power. Selected paging events can be grouped in a discontinuous reception (DRX) cycle of a wireless signal or can be scattered in a subset of time frames based on the above formula. In addition, one or more paging groups can be assigned to each paging event. The paging group may include the identifier of the mobile device assigned, which may be used by the mobile device to identify the paging group assigned to such a device. The paging signals for the mobile device are included in the paging group assigned to the mobile device. By using different paging events and paging groups, false positional calls to the AN OFDMA wireless access network can be reduced, reducing the power consumption of mobile devices and reducing reverse link interference (UL) resulting from such false alarm calls. According to at least one embodiment of the AN OFDMA wireless access network, one may also determine at least one paging group that includes an identifier assigned to all mobile devices within the wireless cell AN.

DETAILED DESCRIPTION [0021] Various forms will now be described with reference to the figures, wherein like reference numerals are used to refer to like elements throughout the description. In the following description, for purposes of explanation, many specific details are provided to provide a thorough understanding of one or more forms. It is clear, however, that such characters can be implemented without these specific details. In other cases, well-known structures and devices are shown in the form of a block diagram to facilitate description of one or more forms.

[0022] Further, various embodiments of the invention are described below. It should be evident that this instruction can be implemented in a wide spectrum of forms and that the particular structure and / or function disclosed in this document is only representative. On the basis of the teachings, one skilled in the art would know that the form disclosed in this document can be implemented independently of any other form and that two or more of these forms can be combined in various ways. For example, the device may be implemented and / or the method may be implemented using any number of forms shown in this document. In addition, the device may be implemented and / or the method may be applied using a different structure and / or functionality in addition to or other than one or more of the forms shown in this document. As an example, many of the methods, devices, systems and devices described in this document are described in the context of establishing device-specific and system-specific paging controls for a mobile communication environment. A person skilled in the art should appreciate that similar techniques may apply to other communication environments.

In the context of the present invention, paging control is provided in a mobile environment (e.g., universal cellular telecommunications system [UMTS], frequency division multiple access system [FDMA], multi-access orthogonal frequency division system [OFDMA], multiplex system with division frequencies [FDM], a system of developed universal terrestrial access

UMTS radio [E-UTRAN], and / or similar mobile access networks). In particular, it has been ensured that the user devices are mixed on the parts of the wireless signal to influence the paging. Due to the fact that many user devices can be served by a single network access point at a given moment, the user devices are called on many separate parts (e.g., resources) of the wireless signal. Each user device can be assigned to a separate signal resource and can monitor such a resource for paging signals. In the event that the access point supports fewer devices than the available paging resources, false alarm calls can be avoided (e.g. when many devices are called as a result of an incoming call for one of the paging devices). If more user devices are available than the available paging resources, you can assign multiple devices to one or more of these separate parts if necessary. This may generate false alarm summaries, but only for devices assigned to a single paging resource. Accordingly, the present invention provides for avoiding or mitigating false alarm calls in FDM, FDMA, OFDMA and / or similar to mobile environments. This may generate false alarm summaries, but only for devices assigned to a single paging resource. Accordingly, the present invention provides for avoiding or mitigating false alarm calls in FDM, FDMA, OFDMA and / or similar to mobile environments. This may generate false alarm summaries, but only for devices assigned to a single paging resource. Accordingly, the present invention provides for avoiding or mitigating false alarm calls in FDM, FDMA, OFDMA and / or similar to mobile environments.

[0024] According to some aspects of the invention, paging resources of wireless signals are defined as a number of time and / or identity-based portions of a wireless signal. For example, the signal may be divided into many distinguishable on the basis of the paging event time. Paging events may include time frames of the discontinuous reception (DRX) cycle of the signal. According to some embodiments, the paging event may include a fraction of the time frame or a plurality of time frames. In addition to the above, a plurality of paging groups for a wireless signal may be provided. The paging group can be distinguished based on the identity of the mobile device (e.g., the international identity of the mobile subscriber [IMSI] or a similar identifier). In this way, ten unique IMSIs of ten assigned devices can be used to create ten different paging groups for such devices. Paging groups can be used to distinguish paging controls for each device. The paging group provided in this manner may be called the paging group identifier or the paging identifier radio network (PI-RNTI).

[0025] As discussed above, the use of paging groups may limit the residence time in the field of paging resources. However, taking into account that the identity of the paging groups can be transmitted via the L1 / L2 control channel (e.g. in an OFDMA system) and thus the paging group identification is taken from the common identity area, the identity can also be a scarce resource. In addition, if the cellular network makes it possible to call multiple paging groups in one L1 / L2 signal control, the size of the available PI-RNTIs may be relatively limited. In addition, the distribution of paging signals in different time frames can help to avoid concentrated reverse link interference (UL). For example, when multiple devices are referenced in a single time frame of the reverse link signal (DL), such devices typically initiate a random access procedure in a common UL time frame that corresponds to a DL time frame. This may cause interference in the UL timeframe. If recall is spread in different DL time frames, UL interference is mitigated. According to this, in at least one embodiment of the invention, resource resources based on the identity and time of the wireless signal are used in combination in a controlled manner. As one example, the paging identifying space may be controlled by L3 protocols by signaling the PI-RNTI range used to identify the paging group. UL interference is alleviated. According to this, in at least one embodiment of the invention, resource resources based on the identity and time of the wireless signal are used in combination in a controlled manner. As one example, the paging identifying space may be controlled by L3 protocols by signaling the PI-RNTI range used to identify the paging group. UL interference is alleviated. According to this, in at least one embodiment of the invention, resource resources based on the identity and time of the wireless signal are used in combination in a controlled manner. As one example, the paging identifying space may be controlled by L3 protocols by signaling the PI-RNTI range used to identify the paging group.

[0026] For time-based paging events, the number of frames (or e.g. subframes or frame groups) used for paging may be limited. As one example, the identity and time based paging system may consist of 'N' time paging and 'M' paging resources based on identity, where 'N' and 'M' are integers. The 'M' and 'N' values ​​can be system parameters transmitted in a wireless signal with system information (e.g., control channel information). The mixing function used to assign mobile devices to the paging group and / or paging events (e.g., based on the user's IMSI) may also be broadcast in the system information. According to particular embodiments of the invention, the selection of pager resources (e.g. paging events and / or paging groups) may be based on a formula containing an integer raised to a permanent power. In at least one of the forms, the integer can be two, which gives the formula "to the second power". In at least one other aspect, the power may be an integer associated with the wireless signal DRX cycle. By using the total number lifted to a solid power (e.g., the power of the other), the recall may be more compatible with other systems. Thus, a mobile device entering a cell serviced by an OFDMA access point can be easily integrated with the paging resources, as discussed in more detail below. paging events and / or paging groups) may be based on a formula containing an integer raised to a permanent power.

Thus, a mobile device entering a cell serviced by an OFDMA access point can be easily integrated with the paging resources, as discussed in more detail below.

[0027] As disclosed in this document, selected time-based signal resources used for paging may be scheduled for a portion of the wireless signal in various ways. As an example, selected time-based parts can be grouped into a continuous DRX cycle segment of the wireless signal. Location, length, number of parts, etc., of a continuous segment can be broadcast with information about the system. After obtaining information about the system, the mobile device can interpret paging resources and identify the resource assigned to the paging signals for this mobile device. In other embodiments, time-based paging sources can be selected from a wireless signal using the "second power" pattern. Such resources can for example be distributed throughout the DRX cycle, depending on the particular pattern, fixed values ​​of the formula and the like. The location of distributed time-based paging resources may also be broadcast in system information to instruct mobile devices how to interpret paging signals.

[0028] When users use the hash function in paging groups and paging occasions to reduce the occurrence of false paging, it may be beneficial to use cell paging as well. For example, when the system information for all mobile devices in a cell is to be updated, searching for all such devices in one paging resource (or, for example, a small amount of paging resources) can be an effective way to distribute system information. On some systems, dedicated system resources are not necessary (e.g., in code division multiple access [CDMA] or broadband CDMA [W-CDMA], where the paging indicator channel may use one or more bits for system call). In the case of E-UTRAN or similar systems in which PI-RNTI is transmitted on the L1 / L2 control channel, it is not always possible to dedicate system resources. Alternatively, the present invention provides for the use of special PI-RNTI or pager group resources in the case of system call (e.g., the "call all devices" resource). According to this alternative, it is not necessary to call paging groups and paging events to provide information about the system. Instead, the user's device can resource "recalling all devices"). According to this alternative, it is not necessary to call paging groups and paging events to provide information about the system. Instead, the user's device can resource "recalling all devices"). According to this alternative, it is not necessary to call paging groups and paging events to provide information about the system. Instead, the user's device can

They may be configured to recognize special PI-RNTI in addition to dedicated or semi-dedicated PI-RNTI. Accordingly, the user equipment may process signals in both PI-RNTIs, which may include system call information, as well as device-specific recall information.

[0036] With reference to the figures, Fig. 1 shows a wireless communication system 100 with multiple base stations 110 (e.g., wireless access points) and multiple terminals 120 (e.g., UTs) that can be used in conjunction with one or more forms. . The base station (110) is generally a fixed station that communicates with the terminals and may also be called an access point, node B or other terms. Each base station 110 provides a communication range for a specific geographic area or coverage area, illustrated as the three geographic areas in Fig. 1, designated 102a, 102b and 102c. The term "cell" may refer to a base station and / or its coverage area depending on the context in which the term is used. To improve system performance, the geographic area of ​​the base station / coverage area can be divided into a plurality of smaller areas (e.g., three smaller areas, according to cell 102a in Fig. 1), 104a, 104b and 104c. Each smaller area (104a, 104b, 104c) can be served by a corresponding base transceiver subsystem (BTS). The term "sector" may refer to the BTS and / or its coverage area depending on the context in which the term is used. For a sector cell, BTS for all sectors of this cell is typically co-located in the cell base station. The transmission techniques described in this document can be used in a system with sector cells as well as in a system with unregistered cells. For simplicity, in the following description, unless otherwise stated, the term "base station" is generally used for a stationary station,

[0037] Terminals 120 are typically distributed throughout the system, and each terminal 120 may be stationary or mobile. Terminals 120 may also be referred to as a mobile station, user equipment, user equipment, or other terms as described above. The terminal 120 may be a wireless device, a mobile phone, a personal digital assistant (PDA), a wireless modem card, and so on. Each terminal 120 may communicate with any one or more base stations 110 of a transmission link (e.g., FL) and a reverse link (e.g., RL) at any one time. The downlink (ang.downlink) refers to a communication link from base stations to terminals and may contain at least paging control information (e.g., identifying paging resources of different terminals 120) and paging signals indicative of an incoming call.

[0038] In the case of a centralized architecture, the system controller 130 connects to the base stations 110 and provides coordination and control of the base stations 110. In the case of distributed architecture, the base stations 110 may communicate with each other if necessary (e.g. using a reverse communication network connecting communication base stations 110). The downlink data transmission often occurs from one access point to one access terminal at or near the maximum data rate that can be handled by the downlink and / or communication system. Additional uplink channels (e.g., control channel, paging resources) can be sent from multiple access points to one access terminal.

[0039] Fig. 2 shows an ad hoc or unplanned / semi-scheduled wireless communication environment 200, according to various embodiments. The system 200 may include one or more base stations 202 in one or more cells and / or sectors that receive, transmit, repeat etc. wireless communication signals with each other and / or one or more mobile devices 204. As shown, each base station 202 may provide a communication range for a specific geographical area, illustrated as four geographical areas, designated 206a, 206b, 206c and 206d. Each base station 202 may include a transmitter channel and a receiver channel, each of which may in turn include a plurality of components associated with signal transmission and reception (e.g., processors, modulators, multiplexers, demodulators, demultiplexers, antennas, etc.), what the specialist in the field will know about. The mobile devices 204 may be, for example, mobile phones, smartphones, laptops, handheld devices, mobile devices, satellite radios, global positioning systems, PDAs and / or any other suitable devices for communication via a wireless network 200. System 200 can be used in combined with various aspects of the invention to provide paging control for FDM, FDMA, OFDMA, E-UTRAN or similar mobile networks as shown herein.

[0040] Fig. 3 is a block diagram of an exemplary system 300 that provides paging control in wireless communication in a mobile operating environment. The system 300 includes a paging device 302 connected to the access point 306 (e.g., a base station) of the mobile operating environment. Access point 306 facilitates wireless communication for one or more mobile devices 304. For example, access point 306 can connect mobile device 304 to a voice network (e.g., mobile network, public switched telephone network, voice over Internet [VoIP]), which facilitates voice communication with remote devices as well as data network (eg Internet, private Intranet or similar, not shown), which facilitate communication with remote devices (eg data server,

[0041] When the mobile device 304 actively engages in data and / or voice communication, common communication and processing functions are used in the device 304 to facilitate such communication as is known in the art (e.g., see Fig. 8, below). If it does not actively engage in data and / or voice communication, the mobile device 304 may remain in an idle state for a longer period of time to reduce processing by the device and associated energy consumption. During idleness, the mobile device 304 processes very small amounts of information transmitted by the access point 306. However, for identifying incoming calls, the device 304 may monitor a subset of the wireless signals transmitted by the access point 306 for paging signals specific to the mobile device 304.

The signals include paging signals, and thus, which should be monitored by the mobile device 304, can be established by the paging device 302.

[0042] According to at least some aspects of the invention, the paging device 302 may include a timing module 308 that divides the wireless signal 316 transmitted by the access point 306 to at least a plurality of signal time frames. The signal time frames may be periodically repeated, e.g., for a plurality of DRX wireless signal cycles 316. Each signal time frame may be used to transmit various information such as synchronization information (e.g., pilot synchronization, primary sequence synchronization [PSS], secondary) sequence synchronization [SSS]), control channel information, paging information, traffic data and / or the like. A subset of the time frames of the wireless signal 316, determined by the dialer 310, may include paging control information for mobile devices (304) served by access point 306 (e.g., see Fig. 6, below). Each time frame containing paging control information can be referred to as a paging event. The dialer 310 may determine paging events from available wireless signal time frames 316 by using different dial patterns.

In at least one form of the invention, the timing module 308 may use a formula comprising an integer raised to a constant power (e.g., InDK. Where Int is an integer and K is a constant) to determine the number, Z, of wireless signal time frames 316. per cycle (e.g., DRX cycle, superframe signal or the like, depending on the network architecture implemented at access point 306). In such embodiments, the dialing module 310 may use a different pattern based on an integer and / or a fixed number to determine the number, N, paging events based on Z time frames.

[0044] The position of paging events in wireless signal 316 may be determined from the patterns used by the dialer 310 to select paging events. Alternatively, the paging event item can be the default item. In one form of the invention, the positions can be grouped in a continuous portion of the wireless signal 316 (e.g., see the system 600A in Fig. 6, below). In another embodiment, the positions may be distributed throughout the wireless signal, as determined by a dialing pattern that selects paging events (e.g., see system 600B of Fig. 6, below). It should be noted that the number, position, length etc. of the paging events may be transmitted to the mobile device 304 as well as the specific paging event / paging group relevant to the mobile device 304.

[0045] The paging device 302 may further include a transmission processor 312. The transmission processor 312 may implement various wireless connections to the access point 306 of one of the embodiments. In one form, the transmission processor 312 may schedule control channel information in the wireless signal 316. The control channel information may determine system information, including identifying paging resources (e.g., paging events / paging groups) of the wireless signal 316. In at least one of the channels. the transmission processor 312 may identify a particular paging resource assigned to the mobile device 304. Such resource may be determined from determined paging resources based on a dialing algorithm that uses the mobile station identifier 304.via a mobile network supporting a mobile device 304 or similar identifier or a combination thereof. According to at least one figure

In accordance with the invention, the transmission processor 312 may select a paging resource for a mobile device 304 based on the following formula:

paging event = (IMSI div L) mod N, where N denotes the total number of paging events of wireless signal 316. The paging resource assigned to mobile devices (304) connected to access point 306, as well as relevant identifiers of mobile devices (304), may be stored in memory 314. The assignment may be maintained as a list, e.g., which may be transmitted on mobile devices (304) in combination with the access point 306. In some embodiments, the pager resource determination for the mobile device 304 may be determined and transmitted in a unicast transmission to such a device 304. Accordingly, the transmission processor may coordinate the wireless signal paging resource 316 with the mobile device 304,allowing the device 304 to process only part of the received signals in an idle state, saving significant computing power and battery life.

[0046] Fig. 4 shows a block diagram of an exemplary paging device 400 for AN OFDMA wireless access network according to an embodiment of the invention. In some embodiments, the paging device 400 may be connected to a base station (not shown) of the wireless network AN (e.g., E-UTRAN) to provide paging control for the base station. In other embodiments, the paging device 400 may be connected to a central controller (e.g., see FIG. 1, above, at 130) to provide paging control for a plurality of base stations of the AN access wireless network. The paging controls provided by the paging device 400 may include paging resources dedicated to one or more mobile devices supported by the access point of the wireless access network AN, as well as signal resources made available to all such devices for broadcasting system information. Accordingly, the paging device 400 may facilitate idle mode for mobile devices with low power consumption, coordinating paging resources with devices as described herein and / or known in the art.

[0047] The paging device 400 may include a timing module 402 that segments the wireless signal transmitted by the access point of the wireless access network AN to a plurality of time frames. In some embodiments of the invention, a number of such time frames per signal or, for example, a DRX cycle may be based on an algorithm comprising an integer (e.g., two) raised to a constant power (e.g., when the constant is determined from a DRX wireless signal cycle). The paging device 400 may further include a dialer 404 that selects a plurality of paging events used to transmit paging signals to one or more mobile devices. The number of paging events, N, is a subset of the number of time frames and can be selected as described in this document.

[0048] The paging device 400 may further include an allocation module 406 that can group the paging events in a continuous portion of the wireless signal. The continuous part can be repeated for each wireless DRX cycle. In one example, allocation module 406 may schedule N paging events to first N time frames (or e.g. other suitable contiguous portion) of selected DRX cycles, periodic DRX cycles, each DRX cycle, etc., wireless signal.

[0049] Alternatively or in addition to the above, the paging device 400 may include a computing module 408. The calculation module 408 may determine a distributed distribution of events.

Apparatus (e.g., in contrast to a continuous system) based on a formula including an integer, Int, raised to a constant power (e.g., DRX cycle factor, number of frames per cycle, cycle length or other suitable constant). In some embodiments, the integer may be the same integer used by the timing module 402 to define the time frames of the wireless signal (or e.g. the DRX cycle). According to particular embodiments, the integer can be two, and the constant can be a DRX cycle constant.

[0050] As a specific, non-limiting example of the above, the computing module 408 may select and / or deploy N paging events using a pattern in the form of:

frame number mod Int ^Λ K <= N-1, where the frame number is an identifier of a particular frame (e.g., a sequential ordinal number of the frame with respect to other frames), Int is the integer used by the timing module 402 to determine the number, Z, time frames of the wireless signal 316, and where K is the DRX cycle constant. In at least one embodiment of the present invention, Int = 2 such that the wireless signal cycles 316 comprise time frames 2ΛΚ and the paging events are determined based on the formula:

frame number mod 2 Λ K <= N-1 [0051] As an alternative example to the above, the paging events can be determined by the following formula:

frame number mod Int Λ (KL) = 0 [0052] In embodiments where Int = 2, the paging events are determined based on the frame number mod 2 '' '(KL) = 0. It should be noted that different patterns can be used in Compute module 408 to organize paging events instead of, or in addition to, the above example formulas. The above formulas should therefore not be interpreted as limiting the present invention to the form as defined herein. Instead, the mechanisms for selecting paging events known in the art or known to those skilled in the art in the context given in this document are included in the present invention.

[0053] In addition to the above, the computing module 408 may assign a paging opportunity to mobile devices supported by the access point or vice versa. Assignment paging events can be based on the identifier of mobile devices. For example, a unique IMSI can be used to determine paging events for a specific mobile device. In one example, the character algorithm (IMSI div L) mod N can be used by the calculation module 408 to select paging events for mobile devices. It should be noted, however, that other suitable examples exist for assigning paging events to a mobile device; such examples known in the art or known to those skilled in the art in the context given in this document are included in the present invention.

[0054] The paging device 400 may further include a grouping module 410. The grouping module 410 may provide paging groups (PI-RNTI) for wireless mobile network signals (e.g., EUTRAN, OFDMA, etc.). Paging groups can be provided at least in part based on identifiers of mobile devices assigned to paging events. For example, paging groups of a common paging event can be distinguished by using different device identifiers of mobile devices assigned to the paging event (e.g., by the calculation module 408). Accordingly, the scheduling module 410 may further sub-divide time-based paging resources into identity-based lookup resources. Such division may increase the number of separate

Suitable resources for sending paging signals to mobile devices, reducing cases of paging false alarm calls in such devices (e.g. resulting from multiple devices assigned to a single paging resource).

[0055] In addition to the above, the paging device 400 may include a transmitting module 412. The transmitting module 412 is configured to facilitate system call with the use of minimal signal resources. In some embodiments, the transmitting module 412 can create a common identity for all remote devices in a cell supported by a wireless access point. The common identity can be associated with selected PI-RNTI sources of the wireless signal. In addition, selected PI-RNTIs can be distributed in the system control information as a paging channel for all mobile devices in the cell. Therefore, the mobile device can monitor the selected PI-RNTI and the dedicated PI-RNTI assigned to the mobile device by means of the computing module 408, as discussed above.

[0056] The paging device 402 may further include a processor 414 and memory 416. Processor 414 may be configured to distribute paging control information to mobile devices supported by the access point or access points of the wireless access network AN. The paging control information may be broadcast in conjunction with synchronization data, control channel data or the like. The information may include a list of paging resources (e.g. paging events and / or PI RNTI) used by the access point, the location of such resources in the wireless signal, and similar information. The information may be stored in the memory 416 along with other relevant data, e.g. algorithms used to determine wireless signal time frames, paging event calls, assigning paging events to devices, or such as identifiers of mobile devices used to generate PI-RNTI and / or assigning devices to signal resources, as described herein. Accordingly, the paging device 400 may, in some embodiments of the subject invention, include a paging system suitable for implementing, distributing and maintaining a paging system for OFDMA, EUTRAN, or similar mobile communications network.

[0057] Fig. 5 is a block diagram of exemplary wireless signal paging resources depending on the form of the present invention. In particular, Fig. 5 illustrates a two-dimensional array of wireless resource paging resources array 500. The matrix 500 may include 'N' pager events and 'M' paging groups (e.g., PI-RNTI). Paging events, in this description, may include wireless signal time segments, such as time frames. Paging groups, as used in this document, may contain parts based on the identity of paging segments. The paging resource corresponds to the intercept block of the paging event / group of paging events 500. Thus, the matrix 500 contains paging resources and thus can provide 'M' x 'N' significant pager resources for 'M' x 'N' mobile devices. In certain embodiments of the subject invention, at least one paging resource may be reserved for broadcasting system call information for all devices operated by a particular cell.

[0058] To distinguish paging groups 'M' for each paging event, the mobile device identifier 506 may be assigned to each resource matrix resource block.

For pager resources reserved for paging signals broadcast in a cellular network, a common identifier may be assigned by the network component to the reserved paging resource and delivered to each device in the cell. Thus, such devices can identify the paging system at least in part using a common identifier.

[0059] According to additional embodiments of the invention, allocation of pager resources may be provided in the DL signal to a mobile device. In one example, the paging of all resources can be broadcast to all devices. Broadcasting may further specify an algorithm for identifying the assigned paging resource based on the identifier of the receiving devices (e.g., IMSI). In such embodiments, mobile devices can thus be used for an algorithm to determine which paging resources need to be monitored for incoming communication. In addition, broadcasting can identify pager system resources that are to be monitored and processed by all cell devices. Alternatively or additionally, the access point may send a unicast message to the mobile device, by specifying paging resources and the locations of such a resource for this device. In these embodiments, the mobile device can simply receive information about paging resources and monitor specific resources to obtain an indication of incoming communication.

[0060] Fig. 6 shows exemplary distributions (600A, 600B) of wireless signal call resources according to one or more aspects of the subject invention. Schedules 600A, 600B show alternative mechanisms for assigning / selecting paging events defined in the manner described in this document. In the first distribution 600A, paging events are grouped into at least one contiguous portion of the wireless signal. The part may be repeated in many DRX cycles of the wireless signal, selected DRX cycles or the like. In particular embodiments of the invention, the number, N, of signal time frames used for paging events may be determined based on the "power second" algorithm (e.g., N = 2^ANDL). Once determined, the paging events are grouped into one or more continuous parts of the DRX cycle. In at least one embodiment of the subject invention, the following formula may be used to determine the number and / or position of the grouped paging events in a wireless signal:

Frame number mod 2 ^Λ K <= N-1 [0061] The location of the continuous parts may be transmitted to remote devices using broadcast messaging, unicast message broadcasting or combinations thereof or the like. In addition, contiguous portions may be included in a single wireless signal cycle, periodically included in multiple cycles, included in selected multiple cycles, modulated in multiple cycles or the like.

[0062] The distribution 600B represents a distributed arrangement of paging events. Many N paging events can be selected based on the "second power" algorithm. Possibility to use

The "second power" algorithm may, for example, consist of selecting individual time segments of a wireless signal for paging resources. In particular embodiments, the base integer 2 can be raised to a constant power, K, according to an algorithm, where K is determined from the DRX cycle length (e.g., based on the integer number of time frames 2^ΛΚ) of the wireless signal. According to at least one aspect, the following formula can be used to determine distributed paging events:

(1) frame number mod 2 Λ (K-L_ = 0 [0063] The paging events may be scattered throughout the DRX signal cycle of the wireless signal based on the frame number of the selected paging events.

[0064] Distributed statements (600A, 600B) may be provided to mobile devices in conjunction with an access point of an AN access wireless network. In addition, devices may provide information about the access point identifier that can be used to provide paging resources where appropriate. By providing distribution information, a mobile device can determine which paging resources are allocated to such a device. Accordingly, the mobile device can go into idle mode when it is not involved in active voice or data communication, essentially only monitoring paging events of the wireless signal relating to the mobile device.

[0065] Fig. 7 is a block diagram of an exemplary system 700 comprising a base station 702 in accordance with at least one embodiment of the invention. Base station 702 may be configured to provide paging control for AT 704 (e.g., mobile devices). For example, the base station 702 may be configured to provide paging resources for wireless signals transmitted by the transmitter 724 and transmit antennas 708. The paging resources may include paging events, paging groups, and the like, as described herein or as known in the art.

[0066] Base station 702 (e.g., access point, etc.) may include a receiver 710 that receives a signal (e.g., broadcast messages [OTA]) from one or more AT 704 through one or more receive antennas 706, the transmitter 724 transmits modulated signals provided by modulator 722 to one or more ATs 704 by transmission antenna 708. Receiver 710 may receive information from receiving antennas 706 and may further include a signal receiver (not shown) for receiving uplink data transmitted by AT 704. Additionally, the receiver 710 is operationally associated with the demodulator 712, which demodulates the information received. The demodulated symbols are analyzed by the processor 714. The processor 714 is connected to a memory 716 that stores information about the functions provided by the base station 702. In one case, the stored information may include protocols for functions performed by the paging device 718. Such functions may include defining time-based segments for the transmitted signal. In addition, the functions may include selecting paging events from a plurality of time-based segments (e.g., using the "second power" algorithm), providing paging groups, obtaining id information from the AT 704, using the identifier information to establish paging groups, assigning AT 704 to one or more paging events and / or paging groups, providing a common opportunity / group of paging groups for paging signals in a cell or the like, as described herein.

[0067] Additionally, processor 714 and memory 716 may be coupled to communication processor 720. Communications processor 720 may schedule the paging channels in wireless signals transmitted by base station 702. Positioning of paging channels may be transmitted to AT 704 or unicast to one or more specific ATs. Accordingly, the AT 704 can receive the arrangement of the paging channels and determine which portion of the wireless signal should be monitored to obtain paging signals from the base station 702.

[0068] Fig. 8 is a block diagram of an example system 800 comprising a mobile terminal 802 configured to facilitate wireless communication in a mobile communication environment. Mobile terminal 802 may be configured to connect wirelessly to one or more base stations 804 (e.g., access point) of an AN access wireless network (e.g., FDM, FDMA, OFDMA, E-UTRAN). The mobile terminal 802 may receive wireless signals (e.g., OTA messages) from the base station 804 in the DL channel and respond to wireless signals on the UL channel as is known in the art. In addition, the mobile terminal 802 may send the identifier associated with the mobile terminal 802 in the UL channel to the base station 804. The identifier may be a unique identifier (e.g., an IMSI, MAC address) or a semi-unique identifier, which is separate with respect to other mobile devices connected to base station 804 (e.g., MSI, IP address, data session identifier or the like). In addition, mobile terminal 802 may extract information identifying paging control systems from signals provided by base station 804. In at least one embodiment of the invention paging control systems may be at least partially based on identifier of mobile terminal 802. According to further embodiments, mobile terminal 802 may use an identifier-based pattern for determining the paging resources assigned to the mobile terminal 802 from the base station 804. According to yet other forms,

The mobile terminal 802 includes at least one antenna 806 (e.g., a sending receiver or a group of such receivers including an input interface) that receives a signal and a receiver 808 that performs typical operations (e.g., filters, amplifies, converts, etc.) on received signal. In general, antenna 806 and transmitter 822 (collectively referred to as a transceiver) may be configured to facilitate wireless data exchange with base stations 804. According to at least some embodiments, communications signal processor 812 may schedule mobile station ID 802 in UL signal transmitted via transmitter 822 to base station 804.

[0070] The antenna 806 and the receiver 808 may also be coupled to the demodulator 810, which may demodulate the received symbols and deliver them to the communication processor 812 for evaluation. It should be noted that the communication processor 812 may control and / or reference one or more components (806, 808, 810, 814, 816, 818, 820, 822) of the mobile terminal 802. In addition, the communication processor 812 may execute one or more modules. , applications, engines or the like (816, 818), which contain information or controls related to the paging controls provided by the base station 804, as described herein.

[0071] Mobile terminal 802 may further include memory 814 that is operatively connected to communication processor 812. Memory 814 may store data to be transmitted, received, and the like, and instructions suitable for conducting wireless remote communication device (804). In addition, memory 814 can store modules, applications, motors, etc. (814, 818, 820, 822) performed by the communication processor 812 above.

[0072] The communication processor 812 may further include a signal processor (812) that obtains a paging group assigned to the identifier provided by the communication processor 812. In some embodiments, the paging group may be associated with a paging event selected from a subset of DL signal time frames. The time frames of the signal may be determined based on a formula comprising an integer (e.g., number two or any other appropriate integer) raised to a constant power (e.g., when such constant is determined from the DRX cycle associated with the DL signal).

[0073] In addition to the above, the signal processor (812) may obtain the location of the paging group and / or paging events within the DL signal. In addition, the signal processor (812) may monitor a paging group / paging opportunity to facilitate identification of paging signals for a mobile terminal 802. In some embodiments, the paging group / paging event location may form part of a continuous DL signal segment reserved for pager resources. In other embodiments, the paging group / opportunity may be a distributed identity / time-based part of the signal. The paging response module 816 may extract information from the paging group / events and determine whether the paging signal is on. If there is a paging signal,

[0074] In at least one embodiment of the invention, the move device 802 may further include a calculation module 818 that can identify the paging occasion associated with the mobile device 802 based on the identifier provided by the communication process 812. The computing module 818 may use a specific pattern to identify paging events. A specific pattern may be stored in memory 814 provided in DL signal by base station 804 or the like. In one example, the pattern may have the form: paging event = (div identifier L) mod N, where L is the constant used to determine the number N of DL signal paging events. As discussed above, after identifying the paging event associated with the mobile device 802, the paging response module 816 may determine whether the paging group associated with the paging event contains a paging signal. If so, the communication processor may initiate a procedure for accessing the AN or other communication network connected to the base station 804.

[0075] The above-mentioned systems have been described in relation to the interaction between several components, modules and / or communication interfaces. It should be noted that such systems and components / modules / interfaces can include the listed components or subranges, some of the given components or subcomponents and / or additional components. For example, the system may include a paging device 302, a base station 702, and a mobile terminal 802, or other combination of these and other components. Subcomponents may also be implemented as components coupled with other components, not with parent components. Additionally, it should be

It should be noted that one or more components can be combined into one component providing combined functionality. For example, timing module 402 may include a dialing module 404 or vice versa to facilitate segmenting a wireless signal into multiple time portions and selecting one or more paging events from such time portions (e.g., using the "second power" algorithm) using a single component. The components may also interact with one or more other components that are not described in the document, but are known to those skilled in the art.

[0076] Furthermore, as can be seen, various parts of the systems and the methods disclosed above may comprise or consist of components, subcomponents, processes, means, methodologies or mechanisms based on artificial intelligence or knowledge or rules (e.g., support vector machine, neutral networks) , expert systems, Bayesian belief networks, fuzzy logic, data fusion engines, classifiers, etc.). Such components, inter alia, and in addition to those already described herein, can automate specific mechanisms or processes that make system parts and methods more adaptable, and more efficient and intelligent.

[0077] In light of the exemplary systems described supra, the methods that may be implemented depending on the disclosed aspect will be better appreciated with reference to the graphs in Figs. 9-11. Although to simplify the explanation, the methodologies are shown and described as a series of blocks, it should be understood and appreciated that the restricted subject is not limited by the order of the blocks, because some blocks may occur in different order and / or simultaneously with other blocks based on what is presented and described in this document. In addition, not all of the illustrated blocks may be required to implement the methodologies described below. In addition, it should be appreciated that the methodologies and description described in the description may be stored in a manufactured article to facilitate the transport and transfer of such methodologies to computers.

[0078] Fig. 9 is a block diagram of an exemplary method900 for providing paging control for AN OFDMA wireless access network according to embodiments disclosed herein. In 902, the method 900 can divide the wireless signal into a plurality of signal time frames. The number of signal time frames may be based on an integer raised to a constant power. In some embodiments, the integer may be a number two or a different appropriate integer. In addition, the constant may, in some embodiments, contain a constant associated with the DRX cycle of the wireless signal. Thanks to the use of such a formula to generate time frames of signals, devices can effectively enter and exit a wireless network using a divided wireless signal.

[0079] In 904, the method 900 may select the number, N, of signal time frames as paging events. In addition, the number N can be a subset of signal time frames. Signal time frames can be assigned to different remote devices in connection with the establishment of paging control for mobile communication. Such communication may be in accordance with protocols relating to a mobile communication network such as FDM, FDMA, OFDMA, E-UTRAN or similar communication and / or access networks. The paging control can be used to facilitate effective idle mobility and power reduction for mobile communication devices connected to the mobile communication network.

[0080] FIG. 10 is a block diagram of an exemplary method 1000 for providing a wireless signal paging resource determined by a & quot; second power & quot; pattern. In 1002,

The method 1000 may determine the paging events of the signal from the time frames of the wireless signal signal based on the "power-to-the-second" pattern as described herein and discussed below. In 1004, the method 1000 may select N paging events from a subset of the signal time frames based on the pattern. In 1006, it is determined whether paging events are grouped in a wireless signal (e.g., in one or more contiguous time frames of the DRX signal cycle signal) or scattered throughout the wireless signal. If they are grouped, the method 1000 can go to 1008; otherwise, the 1000 method can go to 1012.

[0081] In 1008, the method 1000 may select a set of paging events from the wireless signal time frames based on the "second power" pattern. In some embodiments of the invention, the "second power" formula may be:

Frame number mod 2 ^Λ K <= N-1 as described in this document. At 1010, the method 1000 may group the selected set of paging events into a portion of the DRX signal cycle of the wireless signal. In some embodiments, the part may be repeated in many DRX cycles of the wireless signal. For example, paging events may be periodically in parts of many DRX cycles. In another example, paging events may occur in selected DRX cycles, but not in other cycles. It should be noted that various suitable solutions in which the paging event group is modulated in many DRX cycles are contemplated as falling within the scope of the invention. From reference number 1010, method 1000 can go to 1016.

[0082] In 1012, method 1000 may select a set of distributed paging events from wireless signal time frames based on the second "second power" pattern. In some embodiments of the invention, the "second power" formula may be:

Frame number mod 2 Λ (KL) = 0 as described in this document. In 1014, the method 1000 may propagate the paging events of the set across one or more time frames of the wireless signal signal determined by the "to power two" pattern. For example, you can use a formula to choose from which time frames of a DRX cycle signal will be allocated to paging events. Method 1000 may be from 1014 to 1016.

[0083] In 1016, the method 1000 may assign multiple paging groups to a particular paging event. In some embodiments of the invention, the paging groups can be distinguished using the identifiers of the mobile device assigned to the paging group. Thus, the method 1000 can provide a time-based and / or paging resource allocation as described herein. In 1018, the method 1000 may form a common group of paging channels for all remote devices supported by the access point of the wireless access network AN. The paging channel can be used to effectively send system information to all such remote devices. Accordingly, the methodology provides for at least one paging channel for each such dedicated channel device,

[0084] Fig. 11 is a block diagram of an exemplary methodology 1100 that facilitates paging control on an OFDMA AN wireless system. Method 1100, at 1102, can register for wireless communication in the AN access wireless network. The registration may at least include, for example, providing an identifier (e.g., IMSI) of the mobile device to the wireless network

Accessory AN. In 1104, method 1100 can obtain a paging group assigned to the identifier. The paging group can be determined in at least one example based on the mobile device identifier and a plurality of available paging groups for the wireless signal. In one specific example, a paging group can be obtained from an algorithm, such as the M IMSI mode, where M is the number of paging groups available. The paging group can be transmitted via a DL channel and received by the antenna and receiver in a mobile device. In addition, the paging group may be associated with a DL paging opportunity. Such a paging event may be further determined based on a formula comprising an integer (e.g., 2) raised to a permanent power (e.g., determined from the DRX cycle of the wireless signal).

[0085] In 1106, method 1100 may monitor the received paging group assigned to the identifier. In 1108, method 1100 can determine if the paging signal is included in the resource addressed to the paging group. If so, in 1110 the method 1100 can initiate the procedure of access to the wireless access network AN. The access procedure may inform the AN that the mobile device can be reached via a specific base station and that the mobile device is ready to receive incoming communication for such a device.

[0086] Fig. 12 is a block diagram of an exemplary system 1200 for providing paging control in AN OFDMA wireless access network. The system 1200 may include a module 1202 for dividing the wireless signal into a plurality of signal time frames. The module 1200 may determine several such signal time frames, e.g. based on a pattern comprising an integer raised to a solid power. In at least one of the embodiments, the integer may include a number two or another corresponding integer that provides for the effective integration of mobile devices from external systems (e.g., CDMA, W-CDMA) into the local system (e.g., FDM, OFDMA, E-UTRAN etc .). In addition, the constant power may include a constant K, defined at least in part from the DRX cycle associated with the wireless signal. In addition to the above, system 1200 may include a module 1204 for selecting paging events from signal time frames. In some embodiments, the module 1204 may select a subset of signal signal frames as paging events. In addition, the paging event may be scheduled by the module 1204 in different parts of the wireless signal, e.g. as a continuous group of signal time frames (or e.g. one or more DRX cycles of the signal) or distributed time frames, referred to as "to the second power". In one example, you can select continuous time frames based on the formula: frame number mod 2ΛK <= N-1. In at least one alternative example, the scattered time frames can be selected based on the formula: frame number mod 2λ ^ <) = 0. Paging events can be arranged within a signal, whether in a continuous part, or dispersed, may be provided for a remote device (not shown) to facilitate synchronization of paging channels between remote devices and system 1200. [0087] Fig. 13 is a block diagram of sampling system 1300 that facilitates paging control in AN OFDMA wireless. The system 1300 may include a module 1302 for recording wireless communication. The registration can be effected, for example, by means of a mobile communication network via a wireless access point connected to such a network. In some embodiments, module 1302 may include a mobile device identifier in conjunction with registration, where the identifier is a global identifier (e.g., IMSI, MAC address) or a semi-global or local identifier (e.g., IP address, MSI, data session identifier, etc.).

EP 2 186 368 B1

In addition, the paging group may be associated with an identifier by an access point of the wireless access network AN (e.g., E-UTRAN). In at least one of the embodiments, the paging group may be associated with a paging event that is selected from a subset of the time frames of the DL signal signal. The selection of the paging event from the time frames of the signal may, in at least one example, be based on a formula comprising an integer (e.g., the number two) raised to a permanent power. The location of the paging group within the DL may be obtained from such a signal, directly or indirectly, using a pattern and identifier.
