摘要： Systems and methodologies are described that facilitate supporting mobility for UEs and relay eNBs in split-cell relay configurations. Parameters regarding communicating with one or more UEs can be provided to disparate eNBs from a donor eNB to provide mobility for one or more of the UEs or a serving relay eNB. In addition, a donor eNB can request establishment of one or more radio bearers at a target relay eNB for continuing communications with one or more UEs. Moreover, a donor eNB can provide information regarding one or more core network bearers to a target donor eNB to facilitate establishing the core network bearers at the target donor eNB for communicating with the one or more UEs. Furthermore, uplink buffer contents from a relay eNB can be provided to a target donor eNB so communications from the one or more UEs can be continued by the target donor eNB.

摘要： A novel group key distribution and management scheme for broadcast message security is provided that allows an access terminal to send a single copy of a broadcast message encrypted with a group key. Access nodes that are members of an active set of access nodes for the access terminal may decrypt and understand the message. The group key is generated and distributed by the access terminal to the access nodes in its active set using temporary unicast keys to secure the group key during distribution. A new group key is provided every time an access node is removed from the active set of access nodes for the access terminal.

摘要： An algorithm for improving efficiency of data attachment points (DAPs) in a wireless access network (AN) is provided herein. By way of example, the algorithm can identify a serving access point (APs) coupling an access terminal (AT) to the wireless AN. A cost metric for the serving AP can be determined with respect to at least one data network access gateway (AGW) of the wireless AN. The cost metric can be compared with a similar cost metric of a current or default DAP assigned to the AT. If the cost metric of the serving AP is lower than the cost metric of the current/default DAP, the DAP can be re-assigned to the serving AP, minimizing wireless AN resource costs associated with the DAP.
摘要翻译： 本文提供了一种用于提高无线接入网络（AN）中的数据连接点（DAP）的效率的算法。 作为示例，算法可以识别将接入终端（AT）耦合到无线AN的服务接入点（AP）。 可以针对无线AN的至少一个数据网络接入网关（AGW）来确定服务AP的成本度量。 可以将成本指标与分配给AT的当前或默认DAP的类似成本指标进行比较。 如果服务AP的成本度量低于当前/默认DAP的成本度量，则可以将DAP重新分配给服务AP，从而最小化与DAP相关联的无线AN资源成本。

摘要： Disclosed is a method for multiple EAP-based authentications in a wireless communication system. In the method, a first master session key (MSK) is generated in a first EAP-based authentication for a first-type access. A first temporal session key (TSK) is generated from the first master session key (MSK). A second EAP-based authentication is performed, using the first temporal session key (TSK), for a second-type access. First-type access and second-type access are provided after the first and second EAP-based authentications are successfully completed.

摘要： Systems and methods of decoupling session management from connection management of a wireless network by enabling transfer of a session between session controllers. A session transfer component transfers ownership of a session from a source session controller to a target session controller, wherein the session transfer does not necessarily require moving the associated connections therewith. Such transfer employs a Unicast Access Terminal Identifier (UATI) that is updated to inform the related base stations regarding transfer of the session.

摘要： Aspects describe indicating to a mobile station whether an access point supports local Internet Protocol (IP) access. The indication can be sent through utilization of common signaling, which allows the mobile station to have information about the local IP access availability before connecting to the access point. The indication can be sent through utilization of dedicated signaling, which allows the mobile station to find out about availability of local IP access after the mobile station connects to the access point.

摘要： Access control for an access point (e.g., a cell of the access point) may be based on an access mode associated with the access point. For example, depending on the access mode, access control may involve performing a membership check for the access point. Such a membership check may be performed at a network entity, a source access point, or some other suitable location in a network. In some aspects, access control may involve performing a membership check for an access point in conjunction with a context fetch procedure. Such a procedure may be performed, for example, when an access terminal arrives at the access point after experiencing RLF at another access point.

摘要： The disclosure relates to techniques for maintaining minimum quality of service (QoS) communication sessions with a wireless communication device (WCD) over a data-based communication network during a hard handoff between access networks for the WCD. More specifically, the techniques determine whether a closed connection between the WCD and a first access network during a minimum QoS communication session is due to a hard handoff between the first access network and a second access network. In the case of a hard handoff, the techniques maintain open QoS reservations associated with data flows included in the minimum QoS communication session for a predetermined period of time to enable a new connection to be established between the WCD and a second access network. The techniques described herein may especially useful when performing a voice over Internet Protocol (VoIP) call over an Evolution-Data Optimized (EVDO) communication network.

摘要： Methods and apparatuses are provided that facilitate compressing packet headers for communicating among access points. An access point can advertise compression profiles to one or more disparate access points, and the one or more disparate access points can select at least one compression profile for compressing/decompressing packets related to the one or more disparate access points and/or devices communicating therewith. The one or more disparate access points can notify the access point of the selected compression profile, a compression context identifier, and/or static data related to identifying associated packets. In this regard, the access point can compress packets that have the associated static data according to the compression profile and compression context identifier. Similarly, the access point can decompress packets from the one or more disparate access points based on the compression context identifier.
