摘要： A method and system for paging of a wireless client device (WCD). When a wireless communication system encounters a trigger to page a WCD, the system will identify the WCD's most recent serving base station (e.g., the WCD's currently registered base station, or the base station providing the WCD's currently registered coverage area) and will determine whether that base station is a relay base station or rather a non-relay base station. If the base station is a non-relay base station, then the system will provide the initial page of the WCD via just that base station (e.g., as in the zone based paging process discussed above). Whereas, if the base station is a relay base station, then the system will provide the initial (ordinal first) page of the WCD via both that base station and the donor base station that provides the relay base station's wireless backhaul connection.

摘要： Methods and systems are disclosed that support the aggregation of acknowledgement messages and control messages. Advantageously, acknowledgement and negative acknowledgement indications for multiple client nodes are combined into a single aggregated message which is broadcast or multicast to the multiple client nodes. Based on unique identifiers assigned to each client node, client nodes are grouped such that the aggregated acknowledgement messages can be efficiently encoded to conserve both network capacity when they are transmitted, as well as processing capacity when they are parsed by the client nodes. If code division multiple access (CDMA) technology is used, the aggregated acknowledgment message can be transmitted without CDMA spreading to effectively broadcast or multicast it to multiple client nodes. A similar technique can be employed for the efficient broadcast or multicast of aggregated control messages.

摘要： Described are various approaches for considering inter-base-station link congestion levels in connection with handoff of a mobile station when the source base station (or another entity) is able to select a target base station for handoff from among a plurality of base stations. In one aspect, the plurality of base stations are each communicatively linked via a respective inter-base-station link with the source base station serving the mobile station. The source base station (or another entity) selects the target base station from among the plurality of base stations based at least in part on a congestion level of each base station's respective inter-base-station link. The source base station then hands off the mobile station to the target base station.

摘要： A method and apparatus for managing page-response intervals. When a network entity receives a paging trigger signal, the entity determines a page-response interval to use for paging the mobile station, based on one or more factors such as (i) whether the communication is to be provided to the mobile station over the same air interface and/or same air interface protocol that will carry the paging to the mobile station and/or (ii) what network, interface, or other entity the trigger signal comes from and/or what network communication module receives the trigger signal. The network entity then uses the determined page-response interval when paging the mobile station, waiting that determined period of time after each page attempt before attempting to page again or before concluding that the paging effort failed.

摘要： Disclosed is a method and system for release of a UE's context record in response to failure of air interface communication. As disclosed, a wireless communication system includes a base station that has a protocol stack defining a series of logical processing layers through which the base station sequentially processes data for transmission to a UE. The layers include an upper layer and a physical layer at which the base station processes the data for communication over an air interface to the UE. Accordingly, the base station detects failure of air interface communication between the base station and the UE. In response to detecting the failure, and without waiting to detect at the upper layer a further failure corresponding with the failure of the air interface communication, the base station transmits to a network controller a UE-context release request requesting release of bearer context that was established for the UE.

摘要： A method and apparatus to help mitigate interference from an adjacent coverage area. A user equipment device (UE) determines a time division duplex (TDD) frame arrangement of a neighboring base station and reports the determined TDD frame arrangement to a serving base station. The serving base station uses the reported TDD frame arrangement of the neighboring base station as a basis to avoid scheduling downlink transmission of bearer traffic to the UE at times when the TDD frame arrangement of the neighboring base station defines uplink transmission.

摘要： A method and corresponding system to help manage allocation of subframes for relay communication. The allocation may alternate or rotate between which subframes per cycle are used for backhaul communication and which subframes per cycle are used for access communication. By changing the allocation of one or more subframes per cycle between backhaul and access, it becomes possible to only tentatively take away certain subframes of access communication, while reverting to use those subframes for access communication perhaps as soon as the next cycle.
