[0001] The present application relates generally to communication, and more specifically, but not exclusively, to resolution of conflicts related to communication nodes.
Introduction [0002] Wireless communication systems are widely used to provide various types of communication (e.g., voice, data, multimedia services, etc.) to many users. As the demand for high-bandwidth and multimedia services is growing rapidly, there is a challenge for deploying efficient and reliable communication systems with better performance.
[0003] In order to supplement traditional base stations of mobile phone networks (e.g. macrocells), base stations with a small coverage area can be arranged (e.g., installed at the user's home) to provide better wireless coverage for indoor mobile units. Such base stations with a small coverage area are generally known as the access point's base stations, home NodeB nodes or femtocells. Typically, such base stations with a small coverage area are connected to the Internet and a mobile operator's network using a DSL router or cable modem.
In practice, there may be a relatively large number of base stations (e.g., femtocells) used in a given area (e.g., within the coverage area of a given macro cell). In this case, there is a need for effective techniques to
Identifying these base stations so that other nodes in the network can communicate with these base stations. The "Huawei: Detection of conflicting cell identities" document relates to the detection of conflicting cell identifications. For this purpose, global cell identifiers (GCI) and physical layer cell identifications (PLCIs) may be used. The UE equipment could detect, during a cell search, a PLCI conflict, i.e. whether two different cells use the same PLCI. It could then decode the GCI value to assess if there is a conflict.
SUMMARY OF THE INVENTION. EXEMPLARY EMBODIMENTS [0005] The invention is defined by the independent.
[0006] The following is a summary of aspects of the invention. It should be understood that reference to the term aspects in the present specification may relate to one or more aspects of the invention.
[0007] The invention relates to a conflict resolution related to node identifiers. For example, a limited number of node identifiers may be defined within the network such that more than one node (e.g., access point) in the network may be assigned the same identifier. Therefore, when the access terminal is switched from the source node to the destination node, a conflict may arise regarding the identification of the destination node. This document describes various techniques for resolving such a conflict.
[0008] In some aspects, the access terminal to be switched to the destination node may resolve a conflict regarding the destination node by acquiring a unique identifier associated with the destination node. In some implementations, the access terminal sends this unique
53 / 59P31116PL00 that have been conflicted. This identifier to the source node that initiates switch operations. In other implementations, the access terminal uses a unique identifier to initiate a switch operation.
[0009] The access terminal may be configured to detect a conflict. In some cases, the access terminal independently detects the conflict. For example, the access terminal may monitor the identifiers associated with the received signals and generate measurement reports that indicate that multiple nodes use the same identifier.
[0010] As another example, a threshold value of a signal may be assigned to a set of identifiers, identified as possibly subject to a threshold value, then it may be used to invoke acquiring a more unique identifier or to trigger a conflict determination operation on the source node. [0011] In some cases, the terminal available detects a conflict in response to a request. For example, the source node may periodically send a message to the access terminal by requesting the access terminal to send information about the conflict by means of a measurement report.
[0012] The access point may be configured to detect a conflict. For example, the access point may detect a conflict based on the detection of a neighborhood, a target node identified in a switch request, or a received configuration information. Upon detection of the conflict, the access point may send a message to the access terminal requesting that the access terminal acquire a unique identifier in the conflict. In some cases, this instructs the access terminal to use the unique switching operation to resolve the message.
[0013] The conflict resolution may also be used when the access terminal directly accesses the ID node for initialization
53 of the target. For example, in the case where the access terminal establishes communication with the destination node before the destination node obtains resources for the access terminal, the access terminal may send a unique identifier for the source node to the destination node. In this way, the destination node can obtain the appropriate resources from the source node even when the node identifier used by the source node is potentially misleading.

DETAILED DESCRIPTION [0033] Various aspects of the invention are described below. It should be understood that the information herein may be used in a wide range of embodiments and that any particular structure, function or both of them are only represented herein representative. On the basis of the information provided herein, one skilled in the art should recognize that the aspect presented herein can be implemented independently of other aspects and that two or more of these aspects can be combined in various ways. For example, the device may be implemented or the method may be performed using any number of aspects disclosed herein. In addition, such a device may be implemented or the method may be carried out using a different structure, functionality, or structure and functionality in addition to or instead of one or more of the aspects set forth herein. In addition, the aspect may include at least one element of the claim.
[0034] FIG. 1 illustrates several nodes in an exemplary communication system 100 (e.g., part of a communication network). In cells
For example, various aspects of the invention will be described in the context of one or more access terminals, access points and network nodes that communicate with each other. It should be noted, however, that the information herein may be applied to other types of devices or other similar devices to which reference is made using other terminology (e.g., base stations, user equipment, and the like).
[0035] The access points in the system 100 provide one or more services (e.g., network connectivity) for one or more wireless terminals (e.g., access terminal 102) that can be installed internally or that can travel through the associated geographic area. For example, at different times, the access terminal 102 may connect to the access point 104, any one of the set of access points 1 - N (represented by access points 106 and 108 and associated dots) or access point 110. Each of the access points 102 - 110. it can communicate with one or more network nodes (represented, for convenience, by a network node 112) to facilitate the connectivity of a wide area network. Such network nodes may take various forms such as, e.g.
[0036] Each access point in the system 100 is associated with a first type of identifier, referred to herein as the node identifier. In various implementations, such an identifier may include, for example, a physical cell identifier ("PCID"), an offset of a pseudorandom number ("PN") or a pickup pilot. Typically, a fixed amount (e.g., 504) of node identifiers is defined in the given system. In this case, there may be a conflict when the number of points
The access number exceeds the number of node identifiers. FIG. 1 illustrates a simple example of where both identifier 1 is assigned to access point 106 and access point 110. "
[0037] As the access terminal 102 travels in the system 100, the access terminal 102 can be switched from one access point (e.g., access point 104) to another access point (e.g., access point 110). The decision to switch the access terminal 102 to the access point 110 can be made based on whether the access terminal 102 receives particularly strong signals from the access point 110. Here, the access terminal identifies signals from the access point of the node identifier associated with (e.g. inside) those signals. For switching purposes, various information maintained by the source access point 104 (the access point with which the access terminal is currently connected) is transferred to the destination access point 110. In the absence of conflict, this can be accomplished by using the node identifier ("identifier 1") associated with the first access point 110. However, when the conflict occurs, as in the example of FIG. 1, the access point 104 may not be able to determine whether the information should be sent to the access point 106 or to the access point 110.
[0038] To resolve a conflict such as this, the access terminal 102 and / or the access point 104 are configured to detect a conflict and determine a second type of identifier associated with the access point 110. In some aspects, the second type of identifier includes a unique identifier. For example, the second type of identifier may be unique within a larger area than the first type of identifier. In some implementations, the second type of identifier may be unique in the operator's network. In various implementations,
102
110 using a placed
Such a unique identifier may comprise, for example, a global cell identifier ("GCI"), an access node identifier ("ANID"), a sector identifier, a protocol address some other identifier that an access terminal 102 can access inside which can detect
Internet, or uniquely identifies a network point.
[0039] In some implementations, it includes a conflict detector 114, a real or potential conflict between nodes in the system 100. Upon detecting a conflict, the access terminal 102 (e.g., the unique identifier controller 116) may acquire a unique identifier. For example, the access terminal 102 may monitor a signal including a unique identifier that is broadcast by the access point 110. Upon detecting a conflict, the access terminal 102 may also inform the access point 104 about the conflict and / or the unique identifier.
[0040] In some implementations, access point 104 includes a conflict controller 118 that can detect the actual or potential conflict between nodes in the system 100. For example, the conflict controller 118 can independently detect a conflict or, upon receiving a conflict indication from the access terminal 102 the conflict controller 118 may perform additional steps to determine if there is a conflict. In the event of a conflict being detected, the access point 104 may request from the access terminal 102 to acquire a unique identifier.
[0041] After resolving the conflict earlier, the switching access point 104) may initiate operations based on a unique identifier, the access terminal 102 may be efficiently switched to the desired destination access point. As will be described below, in some implementations, an access terminal 102 as discussed (e.g., a switch controller 120 on
In this way,
53 / 59P31116GB00 (e.g. by operation of a switching controller, not shown) may initiate switching operations based on a unique identifier (e.g., when it resolves a conflict).
[0042] The conflict described above can occur in network 200 as shown in FIG. 2, where some access points provide macro coverage, and the remaining access points provide less coverage. In this case, macro coverage areas 204 may be provided by, for example, macro access points of a cellular network with a large area, such as a 3G network, usually referred to as a macro cell network or a wide area network ("WAN"). In addition, smaller coverage areas 206 may be provided by, for example, access points of a network environment in an apartment or building, commonly referred to as a local area network ("LAN"). Because the access terminal ("AT") travels in such a network, the access terminal may be operated at specific locations via access points, which provide a macro coverage, while the access terminal may be served in other locations by access points that provide a smaller coverage area. In some aspects, access points of smaller coverage areas can be used to provide an incremental capacity increase, coverage in a building, and various services, all leading to better user experience.
[0043] In the present description, a node (e.g., access point) that provides cover over a relatively large area may be referred to as a macro node, while a node that provides coverage on a relatively small area (e.g., flat) may be called a femto node. It should be noted that the information herein may be applied to nodes associated with other types of coverage areas. For example, the piko node may provide coverage in an area that is smaller than a macro area and a larger area than the femto (e.g., a coverage inside
53 / 59P31116PL00 of the commercial building). In various applications, different terminology may be used to determine the node macro, femto node, or other access point type nodes. For example, a macro node may be configured or referred to as an access node, a base station, an access point, an eNodeB, a macro cell, and so on. Also, a femto node may be configured or referred to as a Home NodeB node, Home eNodeB, an access point base station, femto cell, and the like. In some implementations, the node may be associated with (e.g., divided into) one or more cells or sectors. A cell or sector associated with a macro node, a femto node, or a pico node can be referred to as a macro cell, femto cell, or pico cell, respectively.
[0044] In the example of FIG. 2, several tracking areas 202 (or routing or location areas) are defined, each of which includes several macro coverage areas 204. Here, the coverage areas associated with tracking areas 202A, 202B, and 202C are indicated by wide lines, and macro coverage areas 204 are represented by hexagons. As mentioned above, tracking regions 202 may also include femto coverage areas 206. In this example, each femto coverage area 206 (e.g., femto coverage area 206C) is shown within one or more macro coverage areas 204 (e.g., a macro coverage area 204B). It should be noted, however, that femto coverage area 206 may not entirely be within the macro of the coverage area 204.
[0045] In a deployment (e.g., dense urban deployment), when a large number of access points, such as femto and pico nodes, are located within a given area, two or more of these access points may be assigned the same identifier. For example, in the macro area 204A
53 cover, femto coverage areas 206A and 206D may be assigned the same identifier. In this case, a node identifier conflict (e.g., a PCID conflict) may occur because a plurality of neighboring nodes that are in the vicinity of the access terminal's access point's access point are announcing the same node identifier. For example, in FIG. 1 access points 106 and 110 may contain femto nodes or pico nodes that announce "identifier 1" using appropriate broadcast pilot signals. Moreover, both of these access points may be close to the access point 104 (e.g., an access point macro) that currently supports the access terminal 102. In this case, the access point 104 may be aware of both access points 106 and 110 and, consequently, may a conflict will appear,
techniques for solving any type of node.
[0046] In general, the conflict described herein may be applied to However, in many embodiments, the macro access points in a given area will be planned such that there will be no conflict associated with switching to the access point of the macro. In such cases, conflict resolution techniques discussed herein can be applied to any non-macro nodes in the network. Such nodes other than macro nodes may include, for example, nodes that are arranged in an unplanned fashion. As mentioned above, such nodes other than macro may contain femto nodes (e.g., arranged by individuals) as well as piko nodes of low power arranged by the operator. Also, as will be discussed in more detail, the node may be limited in some way (e.g. limited in terms of access). Therefore,
[0047] In view of the foregoing, various techniques that can be used to resolve conflict according to the information provided herein will be described with reference to FIGs. 3 - 13. In brief, FIG. 3 illustrates several components that can be used in an access point or access terminal, and the operation network of FIG. 4-13 relate to different conflict resolution techniques.
[0048] For illustrative purposes, the operations of FIG. 4-13 (or any of the other operations discussed or discussed herein) may be described as being carried out by specific components (e.g., system components 100 and / or components shown in FIG. 3). However, it should be noted that these operations can be performed by other types of components and can be carried out using a different number of components. It should also be noted that one or more of the operations described herein may not be used in a given implementation.
[0049] FIG. 3 illustrates several example components that may be embedded in nodes such as access terminal 102 and access point 104 to perform conflict resolution operations as already explained herein. The described components may also be embedded in other nodes in the communication system. For example, other nodes in the system may include components similar to those described for access terminal 102 and access point 104 to provide similar functionality. A given node may contain one or more components described. For example, the access terminal may include a plurality of transmitter transceiver components that allow the access terminal to operate at multiple frequencies and / or communicate using a different technology.
[0050] As shown in FIG. 3, access terminal 102 and access point 104 may include transceivers 302 and 304, respectively, for communication with other nodes. The transmitter 53 / 59P31116PL00 is explained.
receiver 302 includes a transmitter 306 for sending signals (e.g., a message) and a receiver 308 for receiving signals (e.g., comprising a searchable pilot signal). Transceiver 304 includes a transmitter 310 for sending signals and a receiver 312 for receiving signals.
[0051] The access terminal 102 and the access point 104 also include other components that can be used in conflict resolution operations as already herein. For example, the access terminal 102 and the access point may include communication controllers 314 and 316, respectively, to manage communication with other nodes (e.g. sending and receiving messages / indications) and to provide other related functionalities as explained here. Access terminal 102 and / or access point 104 may include and 320 conflict, respectively, for detecting to provide other related functionalities as already explained herein. Access terminal 102 and / or access point 104 may include controllers 322 and 324 identifiers, respectively, for management (e.g., dial, retrieve, request, and so on) node identifiers for providing other related functionalities, as already explained here. The exemplary operations of other components of FIG. 3.
[0052] For convenience, access point 104 is shown in FIG. 3 as conflict detectors 318 and a terminal comprising components that can be used in various examples described below in connection with FIG. 4 - 13. In practice, one or more illustrated components may not be used in a given example. As an example, in some implementations, the access terminal 102 may not include a conflict detector 318, and in some implementations the access point 104 may not include a conflict detector 320. [0053] Referring now to FIG. 4 and 5, in some aspects a conflict associated with a first type of identifier (e.g.
53), can be solved by specifying the use of a second type of identifier (e.g., ANID, GCI, etc.) in combination with switching or other operation.
[0054] This scheme can be used, for example, when an access terminal that is connected to a macro access point activates a search for nearby femto nodes (e.g., a home femto node). When the access terminal detects a signal from the femto node, the access terminal may obtain the identifier of the first type (e.g., pilot ID, sector ID, PCID, etc.) from the signal. If the received signal strength is above the threshold and / or the access terminal is authorized to access the exposed femto node (e.g., the access point is located on the preferred access terminal roaming list), the access terminal may add the access point to the active set for the access terminal. .
[0055] The first terminal accessed to perform the route opening for this femto node from the access point macro establishes a mapping between the identifier of the first type and the identifier of the second type (e.g., ANID, GCI, etc.) in the macro access point. Here, upon receiving the second type of identifier from the access terminal, the macro access point may start detecting the neighborhood by means of this femto node.
The presence of further femto nodes with the same first type identifier in the macro coverage will result in the macro determining the access point that there are multiple access points using the common identifier of the first type (i.e., conflict detection with respect to that identifier). In this case, the macro access point may recognize the presence of these other femto nodes by, e.g., neighborhood detection or by receiving messages from an access terminal that it recognized
53 / 59P31116PL00 conflict. The macro access point can then always request a second type of identifier as soon as it receives a message (e.g., a route open) containing the identifier subject to the conflict. After receiving the second type of identifier from the access terminal, the macro access point can start detecting the neighborhood with this femto node.
[0057] Additionally, as an optimization in some implementations, the access terminal may send messages with the second type of identifier by default. For example, the access terminal may always use the second type of identifier when sending a route open message or other message for its home femto node.
[0058] Referring initially to FIG. 4, as represented by block 402, the access point (e.g., access point 104) receives a message from the access terminal, wherein the message is directed to a node (e.g., a destination node such as access point 110) identified by the first node identifier. For example, as discussed previously, an access terminal may receive a route open request comprising a PN offset or some other type of message comprising a different type of identifier. It should be noted that such a message may have different forms. For example, in various implementations, the message may include a resource setting message for switching, a switching request, requests for adding an active set, interference management signaling, a signal intensity measurement report,
[0059] As represented by block 404, the access point determines whether another node is identified by the first node identifier. The access point can detect such a conflict in various ways. For example, as discussed previously, an access point may receive messages from one or more access terminals that indicate identifiers used by neighboring nodes. IN
In some cases, the access point may perform neighborhood detection and determine that two or more neighboring nodes use an identical identifier. In some cases, the access point may receive information from the configuration manager represented in FIG. 1), which indicate which ones used by the neighbors of the configuration point (e.g., by the node 112, the identifiers are access.) In some cases, the operation in block 404 may include determining whether the identifiers the maintained identifier is a list by the access point. this list of identifiers may contain, for example, identifiers that are not guaranteed to be free from conflict, identifiers that are potentially subject to conflict, or identifiers, which were determined as being subject to conflict. In some aspects, the list of identifiers may include a range of identifier values.
[0060] As represented by block 406 and 408, if no conflict is detected, the access point may perform the corresponding operation (e.g., a switch operation) based on the first node identifier.
[0061] As represented by block 410, if a conflict is detected, the access point sends a message to the access terminal, which specifies that the access terminal should use the second node identifier (e.g., ANID) to establish communication with the node. Such a message can have various forms. For example, the message may include a rejection message (e.g., rejection of the route opening) that instructs the access terminal to use other identifiers.
[0062] As represented by block 412, the access point may then receive a message from the access terminal that includes the second node identifier. The access point may perform the appropriate operation (e.g., a switch operation) based on the second identifier of the node. In some
These implementations may involve tunneling messages comprising a second node identifier to the destination node.
[0063] In some aspects, the operations of FIG. 4 relate to reserving resources by means of a backhaul connection for switching operations (e.g. in conjunction with the operation of adding an active set). In addition, because the conflicting nodes may be limited in certain aspects (e.g. limited in relation or in some other way as discussed below), these operations may also relate to reserving resources for restricted nodes.
[0064] FIG. 5 relates in some aspects to the precision of using a non-conflicting identifier to establish communication with a node. In some aspects, these operations may be complementary to some of the z operations
FIG. 4.
[0065] As represented by block 502, the access terminal (e.g., access terminal 102) selects for transmitting a message to the destination node identified by the first node identifier. As mentioned above in block 402, this message can be sent via an associated access point (e.g., access point 104).
[0066] As represented by block 504, the access terminal determines whether another node can be identified by the first node identifier. This determination can be performed in various ways. As discussed earlier, the access terminal could send a message to the access point 104 using the first node identifier and receive a message from the access point 104 that indicates that there is a specific second usage. In some cases, this determination may involve attempts to communicate with the destination node and receive message from the destination node that indicates that the conflict (and which node identifier).
communication is not authorized. Such a rejection message
It may be received because the context for the access terminal was sent to a node other than the intended destination node due to a node identifier conflict. Also, the access terminal may identify the conflict based on the signals it receives from neighboring access points that indicate the identifiers used by these access points.
[0067] As represented by blocks 506 and 508, if no conflict is detected, the access terminal may use the first node identifier to establish communication with the destination node.
[0068] As represented by block 510, if a conflict is detected, the access terminal may use the second node identifier to establish communication with the destination node.
[0069] Moreover, as represented by block 512, the access terminal may be configured to use the second node identifier to establish communication with the destination node. For example, the access terminal may be configured in this manner after the access terminal detects a conflict. Alternatively, as discussed in the present description, the access terminal may send the second node identifier by default.
[0070] FIG. 6 relates in some aspects to reserving a subset of the node identifier space (e.g., PCID space) for non-macro nodes to simplify conflict resolution. In this way, the node that receives the identifier from the conflict is implementations, the subset can easily determine that
In some designated possible or probable.
the subset contains a set of values that is associated with access points that are designated as not conflicting. In some implementations, the subset comprises a set of designated values that is associated with a closed subscriber group (e.g.
53 / 59P31116PL, as discussed below). In some implementations, the subset comprises a set of designated values that is associated with access points from at least one designated type (e.g., node type). Such a designated type may relate to, for example, one or more of: transmission power, coverage area, or relay capacity.
[0071] As represented by block 602, the access terminal (e.g., access terminal 102) receives a list of node identifiers. This list may include, for example, a subset of the node identifiers discussed above. In some implementations, this list may be received from a serving access point (e.g., access point 104) that announces the list. In some implementations, the target access point or certain other access points (e.g., using neighbors list information) may announce an indication that the second type of identifier (e.g., GCI) is to be used when accessing the target access point. In some implementations, this list can be received from a configuration manager (e.g., network node 112) that tracks a reserved set of nodes that is assigned an identifier from the list.
[0072] As represented by block 604, the access terminal determines a first identifier for communicating with a target access point. For example, as discussed herein, such an identifier may be received by a pilot signal or some other suitable signal.
[0073] As represented by block 606, the access terminal may determine (e.g., independently) whether to use a second identifier (e.g., GCI) to establish communication with the access point. In some aspects, this determination may be based on the first identifier (e.g., by determining the type of the first identifier). For example, if the identifier received in block 604 is in the list received in block 602, the access terminal may acquire a second one.
53 / 59P31116PL00 identifier. Here, acquiring a second identifier may include monitoring other signals (from the target access point) that contain the second identifier. As an example, the target access point may broadcast the second identifier at intervals that are less frequent than the time intervals for which the target access point broadcasts the first identifier.
[0074] As represented by block 608, the access terminal may transmit a message including a second identifier to establish communication with the destination access point. This message can have different forms in different scenarios. For example, the message may include a signal strength measurement message, a radio resource report, or a switching request. In a typical implementation, the access terminal (e.g., access terminal 102) includes associated PCID and GCI values in a measurement report that the access terminal sends to its serving access point (e.g., access point 104). In addition, as described below in connection with FIG. 7, in certain circumstances the access terminal may send this information to the destination access point.
[0075] As represented by block 610, upon receipt of this information, the serving access point may initiate a switching procedure using the GCI value. Thus, the serving access point will set the resources in the target cell and will send the switch command to the access terminal.
[0076] FIG. 7 relates in some aspects to selecting an identifier to be provided to a destination access point, the identifier being associated with a source access point. For example, the access terminal may use the GCI of the source access point in cases where the access terminal accesses the target access point directly without prior preparation of the switching. In this case, the terminal
The access point may include the GCI of the source access point when accessing the target access point. This allows the target access point to resolve any conflict regarding the identification of the source access point. The target access points can then download the context for the access terminal from the appropriate source access point, and complete the switching. These operations are described in blocks 702 - 706 in FIG. 7.
[0077] As represented by block 702, the access terminal selects identifiers (e.g., an identifier e.g.
GCI) of a first set identifier such as PCID with a target of a second identifier such as GCI) associated access point (e.g., access point 110 aspects, selection of a second identifier may be based on whether the first identifier is on the received list of identifiers (e.g. as conflict-free, based on the node type of the access point, etc.) in a similar manner as previously discussed in connection with FIG. 6. As mentioned above, in some aspects the choice of the second identifier may be based on loss of communication with the source access point ( e.g., access point 104).
[0078] As represented by block 704, the access terminal transmits the selected access point identifier during establishment to the target communication with the destination access point. For example, the access terminal may include the GCI of the source access point in the connection request message.
[0079] As represented by block 706, the source access point may then use the selected identifier to establish communication and / or obtain configuration information from the source access point. In this way, the source access point may receive context information for the access terminal to complete the switching.
53 / 59P31116PL00 [0080] FIG. 8 relates, in some aspects, to operations that the access point and / or the access terminal can carry out together with the detection and resolution of node-node conflicts. In some aspects, these operations are complementary to the operations described above in connection with FIG. 5.
[0081] As represented by block 802, the access point (e.g., access point 104) determines if multiple nodes use the same identifier when the identifier is of the first type (e.g., PCID). As mentioned above, the access point can detect such a conflict based on measurement reports, neighborhood detection and received messages.
[0082] As represented by blocks 804 and 806, if no conflict is detected, the access point may continue normal operations. For example, the access point may determine whether to perform a handover based on the identifier of the first type received by means of a measurement report.
[0083] As represented by block 808, if a conflict is detected, the access point may issue a request to obtain an identifier of a second type that is associated with the identifier of the first type being subject to the conflict. For example, if the conflicting PCID has been received via a measurement report from an access terminal (e.g., access terminal 102), the access point may send a request to the access terminal to acquire a GCI associated with the PCID. The access terminal may then acquire GCI, e.g. as discussed in the present description.
[0084] As represented by block 810, the access point may then receive a response from the access terminal that includes GCI. Because the conflict will now be resolved (e.g., at the access point), in block 812, the switching operation may be initiated (e.g., via an access point) using the received GCI.
[53] FIG. 9A and 9B relate, in some aspects, to the use of a threshold value for inducing the acquisition of a unique identifier (e.g., GCI). In some cases, the access terminal can independently determine when to acquire a unique identifier; i.e. without instructing for this purpose by another node (e.g. access point).
[0086] As represented by block 902, the access terminal may receive a defined set of identifiers of the first type (e.g., list of node identifiers described above). In some implementations, this information may be defined by and / or provided by a serving access point (e.g., by an identifier controller 324) or some other node. For example, the serving access point may identify all of the PCIDs that are or may be subject to conflict and provide a list of these identifiers to the access terminal.
[0087] As represented by block 904, the access terminal may also receive a threshold value associated with a defined set of identifiers. For example, this threshold value may determine a threshold signal strength value for a received signal that triggers acquisition of the GCI by the access terminal. In some implementations, this threshold may be defined by and / or provided by the serving access point (e.g., by the threshold controller 334) or some other node. For example, this threshold value may be defined to be lower (e.g., a few dB) than the threshold value of the intensity of the received signal u that triggers the switching operation. In some implementations, the threshold may be specified as a relative offset to the signal strength of the target access point,
[0088] As represented by block 906, at some point the access terminal will receive a signal that is associated with the identifier of the first type. As represented by block 908, the access terminal (e.g., comparator 330) may determine whether the received identifier is in the list of identifiers. Additionally, the access terminal (e.g., signal processor 332, which may be implemented in or operable in conjunction with the receiver 308) determines whether the received signal's received signal strength for the signal received by block 906 is greater than the equal threshold value.
[0089] As represented by blocks 910 and 912, if the criteria of block 908 is not met, the access terminal may continue to monitor signals from neighboring access points.
[0090] As represented by block 914, if the criteria of block 908 is satisfied, the access terminal acquires an identifier of a second type (e.g., GCI) that is associated with an identifier received at block 906. As discussed earlier, this may involve monitoring the broadcast signal with specified periodicity.
[0091] As represented by block 916, the access terminal (e.g., report generator 328) sends a message to the access point including the identifier blocks 906 and 910 and the intensity of the received signal (e.g., a signal received at block 906). This message may be sent shortly after the unique identifier is obtained in block 910 or at another time. In some implementations, this information is sent in a measurement report. For example, this report may be sent when the intensity of the received signal for the received signal (e.g., from the target access point) exceeds the switching threshold.
[0092] As represented by block 918, because any conflict will now be solved, the access point acquired in the signal for
(E.g., a switching controller 326) determines whether to initiate a switch operation based on the identifier and the received signal strength provided in this message. As discussed in the following description, if a handover operation is indicated, the access point will use a unique identifier for preparing the target access point and will send the switch command to the access terminal.
[0093] In some aspects, the scheme of FIGs. 9 may be beneficial in high mobility environments. For example, this scheme may provide faster handover because the GCI may be read before the signal strength of the target access point becomes strong enough for the switching request.
[0094] FIG. 10A and 10B relate to some aspects of the scheme in which the access terminal reports the reception of a signal that has exceeded a threshold (e.g., threshold value GCI) to the access point. In this case, the access point may determine whether a conflict is possible and, if so, instruct the access terminal to acquire a unique identifier (e.g., GCI). Here, block operations 1002 - 1012 may be similar to block operations 902 -912, respectively.
[0095] However, if the criteria are met at block 1010, at block 1014, the access terminal sends a message to the access point that includes the identifier acquired at block 1006 and the intensity of the received signal for the associated signal. This message can be sent immediately after obtaining the identifier in block 1006 or at some other time. In some implementations, this information is sent in a measurement report.
[0096] As represented by block 1016, the access point determines whether the conflict is likely based on the received information. For example, this determination may be based on whether multiple nodes use the same identifier. In addition, this determination may optionally be
Based on the received signal strength of any detected signals that include this identifier.
[0097] As represented by blocks 1018 and 1020, if no conflict is detected, the access point may continue normal operations. For example, the access point may determine whether to perform a handover based on the identifier of the first type received by means of a measurement report.
[0098] As represented by block 1022, if a conflict is detected, the access point sends a message to the access terminal that requested the access terminal to acquire a unique identifier (e.g., CGI) associated with the identifier being subject to the conflict. As represented by block 1024, the access terminal may then retrieve the identifier as discussed in this specification and send the identifier to the access point (e.g., using a measurement report).
[0099] As represented by blocks 1026 and 1028, the access point resolves the conflict thereby and determines whether to initiate switching based on the unique identifier and intensity of the received signal (e.g., as discussed herein).
[0100] FIG. 11 relates in some aspects to collision detection (e.g., independent detection) by an access terminal. In particular, this scheme relates to an access terminal that provides a measurement report with collision information.
[0101] As represented by block 1102, the access terminal detects a collision for a given identifier of the first type. For example, based on monitored pilot signals or other appropriate signals, the access terminal may determine that multiple access points use the same PCID as discussed herein.
[0102] As represented by block 1104, an access terminal may optionally acquire an identifier of a second type (e.g., GCI) associated with an identifier for which a collision occurs.
53 / 59P31116PL00 was indicated. Again, this operation can be carried out as discussed earlier.
[0103] As represented by block 1106, the access terminal sends a measurement report that contains multiple entries for the identifier for which the collision was indicated. For example, if the two access terminals use a PCID value of 12, the measurement report may include two separate entries corresponding to the PCID value of 12. Additionally, the measurement report may optionally include a unique identifier (e.g., GCI) associated with each of these entries. [0104] FIG. 12 relates in some aspects to independent collision detection by an access terminal. In particular, this scheme refers to an access terminal that sends a measurement report if it detects a collision.
[0105] As represented by block 1202, the access terminal detects a collision for a given identifier of the first type. As above, the access terminal may determine that multiple access points use the same PCID based on monitored pilot signals or other appropriate signals, as discussed herein.
[0106] In some aspects, the collision detection may be indicated based on whether at least two nodes currently use the same identifier or have recently used the same identifier. For example, a collision can be indicated if the access terminal currently receives synchronization or pilot signals from multiple access points that use the same PCID. In addition, a collision can be indicated if the access terminal has received synchronization or pilot signals from multiple access points within a certain period of time (e.g., the last 10 seconds). Under certain conditions, this time period may be set to zero (e.g., for a fast moving access terminal). Also, a collision can be indicated if the access terminal has received synchronization or pilot signals from a plurality of access points
In the time period associated with the defined number of switching operations (e.g. the last four transfers). The latter scheme may advantageously allow slow moving terminals to send reports to cover the desired geographical area. In other words, this scheme allows detection of repeating node identifiers in a wider geographical area.
[0107] As represented by block 1204, the access terminal may optionally acquire an identifier of a second type (e.g., GCI) associated with the identifier for which the collision was indicated. Again, this operation can be performed as discussed earlier.
[0108] As represented by block 1206, the access terminal sends a measurement report if the collision was detected in block 1202. Additionally, the measurement report may optionally include a unique identifier (e.g., GCI) associated with each of these entries.
[0109] FIG. 13 relates in some aspects to an access terminal that provides a collision report on request. As represented by block 1302, the access terminal receives the request for the collision report. For example, the network may periodically request that the access terminal send a measurement report with collision information. This request may specify one or more identifiers (e.g., PCID) for which collision information is requested. This identifier may be the identifying node of the requesting (e.g., serving access point). Alternatively, this request may include a wildcard, and the access terminal is requested to report all detected collisions. As represented by block 1304, the access terminal monitors signals from neighboring access points and detects collisions, if applicable (block 1306). As represented by block 1308, the access terminal sends a collision report if a collision was detected in block 1306.
The number of operations from
In the event that the terminal access does not have any collision information, the access terminal may respond with the "no event" message or may not provide. Note that one or more of FIG. 11 - 13 can be combined in various ways in different implementations.
[0110] As mentioned above, the information contained herein may be implemented in a network that uses macro access points and femto nodes. FIG. 14 and 15 illustrate examples of how access points can be used in such a network. FIG. 14 illustrates in a simplified manner how cells 1402 (e.g., macro cells 1402A - 1402G) of a wireless communication system 1400 can be served by corresponding access points 1404 (e.g., access points 1404A - 1404G). Here, cell macro 1402 may correspond to the macro areas 204 of the coverage of FIG. 2. As shown in FIG. 14, access terminals 1406 (e.g., 1406A 1406L access terminals) may be scattered at various locations in the system over time. Wireless communication system 1400 can provide service in a large geographical area. For example, each of the macro cells 1402A - 1402G can cover several blocks in a neighborhood or a few square miles in a rural environment. Wireless communication system 1400 can provide service in a large geographical area. For example, each of the macro cells 1402A - 1402G can cover several blocks in a neighborhood or a few square miles in a rural environment.
[0111] FIG. 15 illustrates an example of how one or more femto nodes can be deployed within a network environment (e.g., system 1400). In the system 1500 of FIG. 15, many femto nodes 1510 (e.g. femto nodes 1510A and 1510B) are installed in a network environment with a relatively small area
Cover (e.g., in one or more dwellings of the user 1530). Each femto node 1510 may be coupled to a wide area network 1540 (e.g., the Internet) and a mobile operator's core network 1550 by means of a DSL router, cable modem, wireless link or other means of communication (not shown).
[0112] The female owner of node 1510 may subscribe to a mobile service, such as, for example, a 3G mobile service offered by the mobile operator's core network 1550. Additionally, the access terminal 1520 may be capable of operating in both macro environments and network environments with a smaller coverage area (e.g., flat). In other words, depending on the current location of the access terminal 1520, the access terminal 1520 may be served by the mobile macro access point 1560 associated with the mobile operator's core network 1550 or any one of the femto nodes 1510 (e.g. femto nodes 1510A and 1510B that are they are placed inside the appropriate flat 1530 of the user). For example, when the subscriber is outside of his home, the subscriber may be served by a standard macro access point (e.g. access point 1560), and when the subscriber is near or within your home, the subscriber can be served by a femto node (e.g., node 1510A). In this case, femto node 1510 can be backwards compatible with legacy access terminals 1520.
[0113] Femto node 1510 can be operated on a single frequency, or in an alternative embodiment, on multiple frequencies. Depending on the particular configuration, a single frequency or one or more of the plurality of frequencies may overlap one or more frequencies used by the macro access point (e.g., access point 1560).
[0114] In some aspects, the access terminal 1520 may be configured to connect to the preferred femto node (e.g.
[0038] Femto access terminal node 1520), if such communication is possible. For example, whenever the access terminal 1520A is inside the user's flat 1530, it may be desirable for the access terminal 1520A to only communicate with the home femto node 1510A or 1510B.
[0115] In some aspects, if the access terminal 1520 operates within the macro of the cellular network 1550 but is not in the most favorable network (e.g., as specified in the preferred roaming list), the access terminal 1520 may continue to search for the most preferred network (e.g., preferred femto node 1510) using the Better System Reselection ("BSR") system, which may include periodic scanning of available systems to determine if better systems are currently available, and subsequent attempts to establish association with such preferred systems. By means of the acquisition entry, the access terminal 1520 may limit the search to a specific band and channel. For example, the search for the most preferred system can be repeated periodically. After detecting the preferred femto node 1510,
[0116] Femto node may be limited in some aspects. For example, a given femto node can only provide specific services to specific access terminals. In implementations with a so-called limited (or closed) connection, a given access terminal can only be served by a mobile macro cellular network and a defined femto set of nodes (e.g., femto nodes 1510 that are inside a corresponding flat 1530 of the user). In some implementations, the node may be limited such that it does not provide, for at least one node, at least one of: signaling, data access, registration, paging or service.
[0117] In some aspects, a restricted femto node (which may also be referred to as a Home NodeB node of a closed subscriber group) is one that provides services to a limited secured set of access terminals. This set can be temporarily or continuously expanded if necessary. In some aspects, a closed subscriber group ("CSG") can be defined as a set of access points (e.g., femto nodes) that share a common access control list of access terminals. The channel on which all femto nodes operate (or all limited femto nodes) in the region can be referred to as femto channel.
[0118] Therefore, different dependencies may exist between a given femto node and the given access terminal. For example, from the perspective of the access terminal, the open femto node may refer to the femto of the node with unrestricted association (e.g., the femto node allows access to any access terminal). A restricted femto node may refer to a femto node that is limited in some way (e.g., limited in association and / or enrollment). The home femto node may refer to a femto node, to which the access terminal is authorized to access or act on it (e.g., permanent access is provided for a defined set of one or more access terminals). Hospitable femto node can refer to the femto node, against which the access terminal is provisionally authorized to access or act on it. The foreign femto node may refer to a femto node, to which the access terminal is not authorized to access or act on it, except for possible emergency situations (e.g., connection to number 911).
[0119] From the perspective of a restricted femto node, the home access terminal may refer to an access terminal that is authorized to access a restricted femto node (e.g., the access terminal has constant access to
53 (femto nodes). A guest access terminal may refer to an access terminal with temporary access to a limited femto node (e.g., limitation based on limit time, utilization time, bytes, criterion or criteria connection counter or any other foreign access terminal may apply to an access terminal that has no access terminal) permission to gain access to the restricted femto node, except for possible emergency situations, for example, such as connection to number 911 (e.g., an access terminal that does not have credentials or permission to register on a restricted femto node).
[0120] For convenience, the present invention describes various functionalities in the femto context of a node. It should be noted, however, that the pico node may provide the same or similar functionality for a larger coverage area. For example, the pico node may be limited, the home pico node may be defined for a given access terminal, and so on.
[0121] The information contained herein may be implemented in various types of communication devices. In some aspects, the information provided herein may be implemented in wireless devices that may be multi-access communication, which may support communication for multiple wireless access terminals. In this case, each terminal may communicate with one or more access points via transmission on the forward and reverse link. The forward link (or downlink) refers to the communication link from the access points. The reverse link (or uplink) refers to the terminal link to the access points. This communication link can be established using the system one input - one output, a system many inputs - many outputs ("MIMO"), or other type of system.
[0122] For illustrative purposes, FIG. 16 describes examples of communication components that can be used in the system at the same time for terminals and for communication with
In the context of a MIMO-based system 800. The system 1600 uses multiple (NT) transmit antennas and multiple (NR) receive antennas for data transmission. The MIMO channel created by the NT transmit antennas and NR receive antennas can be decomposed into NS independent channels, which also refer to spatial channels, where N<sub>S</sub> <min {NT, NR}. Each of these NS independent channels corresponds to the dimension. The MIMO system can provide increased performance (e.g., higher bandwidth and / or better reliability) when using additional dimensions created by multiple transmission and reception antennas.
[0123] System 1600 may support time division ("TDD") and frequency division duplex ("FDD") duplex. In the TDD system, transmissions on the forward and reverse links take place in the same frequency region, so that the reciprocity principle makes it possible to estimate the forward link channel from the reverse link channel. This enables the access point to extract the gain shaping the transmission beam on the forward link when multiple antennas are available at the access point.
[0124] The system 1600 includes a wireless device 1610 (e.g., an access point) and a wireless device 1650 (e.g., an access terminal). At device 1610, traffic data for a number of data streams is provided from data source 1612 to transmission data processor 1614 (& quot; TX & quot;).
[0125] In some aspects, each data stream is transmitted via respective transmission antennas. The TX data processor 1614 formats, codes, and interleaves the traffic data for each data stream based on the particular coding scheme selected for that data stream to provide the encoded data.
[0126] The coded data for each data stream may be multiplexed using pilot data using OFDM techniques. Pilot data is usually a known data pattern,
The multiplexed pilot data and the encoded data for each data stream are then modulated (i.e., symbol-mapped) based on a particular modulation scheme (e. G., E.g., in a known manner) and may be used in a receiver system to estimate the u-channel response. BPSK, QSPK, M-PSK or M-QAM) selected for the data stream to provide modulation symbols. The throughput, coding and modulation for each data stream may be determined by instructions provided by the processor 1630. The data memory 1632 may store the program code, data and other information used by the processor 1630 or other components of the device 1610.
[0127] The modulation symbols for all data streams are then provided to the MIMO TX processor 1620, which may then process the modulation symbols (e.g., for OFDM). TX MIMO processor 1620 then provides NT modulation symbol streams to NT transceivers ("XCVR") from 1622A to 1622T. In some aspects, the TX MIMO processor 1620 applies beamforming weights to the symbols of the data streams and to the antenna from which the symbol is being transmitted.
[0128] Each transceiver 1622 receives and processes a corresponding symbol stream to provide one or more analog signals, and further conditions (e.g., amplifies, filters, and converts the frequency into a higher) analog signals to provide a modulated signal suitable for transmission through using the MIMO channel. The NT of the modulated signals from the transceivers 1622A to 1622T is then transmitted from the antennas NT 1624A to 1624T respectively.
[0129] In apparatus 1650, transmitted modulation symbols are received by NR antennas 1652A to 1652R, and received signals from each antenna 1652 are provided to the respective transceiver ("XCVR") from 1654A to 1654R. Each transceiver 1654 conditions (e.g., filters, amplifies,
And converts the frequency into a lower one) the corresponding received signal, digitizes the conditioned signal to provide samples, and further processes the samples to provide a corresponding "received" symbol stream.
[0130] The received data processor 1660 ("RX") then receives and processes the NR received symbol streams from NR transceivers 1654 based on the respective processing technique of a specific receiver to provide NT "detected" symbol streams. The RX data processor 1660 then demodulates, deinterleaves, and decodes each detected symbol stream to recover traffic data for the data stream. The processing of the RX data 1660 is complementary to the processing performed by the MIMO 1620 TX processor and the TX data processor 1614 on the 1610 device.
[0131] Processor 1670 periodically determines which pre-coding matrix to use (discussed below). The processor 1670 formulates a reverse link message including a part with a matrix index and a part with a degree value. The data memory 1672 may store the program code, data and other information used by the processor 1670 or other components of the 1650 device.
[0132] The reverse link message may include various types of information relating to the communication link and / or the received data stream. The reverse link message is then processed by the TX data processor 1638, which also receives traffic data for a number of data streams from the data source 1636, modulated by the modulator 1680, conditioned by the transceivers 1654A to 1654R and transmitted back to the device 1610.
[0133] In the device 1610, the modulated signals from the device 1650 are received by the antennas 1624, conditioned by the transceivers 1622, demodulated by the demodulator
(DEMOD) 1640 and processed by the RX data processor 1642 to extract the reverse link message transmitted by the device 1650. The processor 1630 further determines which pre-coding matrix to use to determine the beamforming weights, and then processes the extracted message.
[0134] FIG. 16 also shows that the communication components may include one or more components that perform conflict control operations as explained above. For example, the conflict control component 1690 may cooperate with the processor 1630 and / or another component of the device 1610 to send / receive signals from / to another device (e.g., device 1650) as already explained herein. Similarly, the conflict control component 1692 may cooperate with the processor 1670 and / or other components of the device 1650 to send / receive signals from / to another device (e.g., device 1610).
