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： 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： Systems and methodologies are described that facilitate compressing headers for relay nodes. In particular, a plurality of internet protocol (IP) headers, tunneling protocol headers, and/or other routing headers in a packet can be compressed to facilitate efficient communications of packets between relay nodes and/or a donor access point. A donor or other upstream access point can be provided with a filter mask, bit stream, and filter mask identifier generated by a related relay node for packets having given static header data. Thus, the donor or other upstream access point can apply the filter mask to incoming packet headers, and where a resulting bit stream matches the received bit stream, can replace at least a portion of the packet headers with the filter mask identifier. The relay node can subsequently decompress the packet headers based on the filter mask identifier. Similar functionality can be used for compressing uplink communications.

摘要： Apparatus and methods of allocating identifiers in a communication system include receiving, at a first access point, a set of physical layer identifiers used by a plurality of access points, with assistance from an access terminal. The apparatus and methods further include detecting, relative to one of the plurality of access points, a conflicting physical layer identifier. Additionally, the apparatus and methods include selecting, at the first access point, a first physical layer identifier distinct from the conflicting physical layer identifier.

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： Techniques for determining resources to use for peer-to-peer (P2P) communication are disclosed. In an aspect, a network entity may receive feedback information (e.g., resource usage information and/or channel state information) from P2P devices and may perform resource partitioning based on the feedback information to allocate some of the available resources for P2P communication. The allocated resources may observe little or no interference from devices engaged in wide area network (WAN) communication. In another aspect, P2P groups may perform resource negotiation via a WAN connection (e.g., with little or no involvement by the WAN) to assign the allocated resources to different P2P groups. In yet another aspect, a device may autonomously determine whether to communicate with another device directly or via a WAN, e.g., whether to initiate P2P communication with another device and whether to terminate P2P communication. In yet another aspect, a network entity may participate in resource negotiation by P2P devices.

摘要： Methods and apparatuses are provided that facilitate allowing position determination of devices in wireless networks with home evolved Node Bs (HeNB). An HeNB can determine its location based at least in part on positioning measurements from one or more devices. The HeNB can additionally or alternatively register its location or other location parameters with a positioning server for subsequent provisioning as assistance information for determining a device position. Moreover, a device can request assistance information related to a different base station where the HeNB is not registered with the positioning server.
