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： Systems and methods are disclosed to enable multiple neighbour base stations or access points (APs) preparation for handover robustness. The systems and methods include generating a handover request message at a source base station (BS) for user equipment (UE) if the UE detects at least one neighbour BS. The handover request message may include a handover imminent flag. The handover request message is transmitted to the neighbour BS, wherein if the handover imminent flag indicates that the handover is not imminent, the neighbour BS does not reserve a radio network temporary identifier (RNTI) for the UE.

摘要： Systems and methodologies are described that facilitate packet routing among relay eNBs in a wireless network. Packet data convergence protocol (PDCP) layer communications from a user equipment (UE) can terminate at a donor evolved Node B (eNB) and vice versa. In this regard, a relay application protocol (RAPP) layer is defined to transport application layer control data among relay eNBs to facilitate appropriate routing. RAPP layer messages can be similar to control messages at other application layers, such as S1-AP, X2, etc., while additionally including a relay UE identifier for routing the messages among relay eNBs. In addition, RAPP layer messages can exclude other parameters normally defined in other application layers to protect security and encryption/decryption details.

摘要： Described herein is methodologies for efficient utilization of backhaul resources of a network for delivering paging data to an access terminal (AT) without sacrificing delay performance. A location that buffers data for an AT can be adaptively changed based on factors such as the location of the AT, applications utilized by the AT, and a recent activity level of the AT. To facilitate this determination, an AT can be configured with one or more registration boundaries. An AT can be configured with a small registration radius such that if the AT does not move outside of the small registration radius, data can be delivered directly to a data attachment point for the AT. If the AT moves outside of the small registration radius, the registration radius can be switched to a large registration radius and the access gateway can instead locally buffer data for the AT.
摘要翻译：这里描述了用于有效利用网络的回程资源的方法，用于在不牺牲延迟性能的情况下将寻呼数据传送到接入终端（AT）。可以基于诸如AT的位置，AT使用的应用以及AT的最近的活动级别等因素自适应地改变缓冲AT的数据的位置。为了便于确定，AT可以配置一个或多个注册边界。 AT可以被配置为具有小的注册半径，使得如果AT不移动到小注册半径之外，则可以将数据直接传送到AT的数据连接点。如果AT移动到小注册半径之外，则注册半径可以切换到大的注册半径，而接入网关可以代替本地缓冲AT的数据。

摘要： Systems and methods for switching among heterogeneous networks and inter-working between a source access system and a target access system. An inter-system handoff control component can facilitate setting an IP tunneling by the mobile unit, wherein IP addresses for inter-working security gateway and Radio Access Network of the target access system can be identified. The inter-system handoff control component can then implement tunneling between the source system and the target system, wherein signaling/packeting associated with the target system can be transferred over the source system.
