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. An access point receiving packets to be compressed can provide a disparate access point with a compression context and an uncompressed packet. The disparate access point can generate a decompression context related to subsequent packets having similar header values and can store the decompression context with the context identifier. The access point can subsequently compress received packets having similar header values and communicate the compressed packets with the context identifier to the disparate access point. The disparate access point can apply the previously generated decompression context associated with the context identifier to decompress the packets.

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： 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.

摘要： Systems and methodologies are described that facilitate providing user plane support for internet protocol (IP) relays. Service data units (SDU) received at a radio communication layer can be provided to an upper communication layer, such as a packet data convergence protocol (PDCP) layer, without regard to sequence numbers. The upper communication layer can handle reordering of the received protocol data units. Since communications related to a plurality of devices through one or more IP relays can be mapped over a single bearer, allowing reordering at the upper communication layer can mitigate delay caused where a donor or other upstream access point is delayed in providing a sequential SDU related to one of a plurality of devices downstream. In this regard, SDUs related to other devices can be processed by the upper communication layer while waiting for the sequential SDU.
摘要翻译：描述了有助于为互联网协议（IP）中继提供用户平面支持的系统和方法。在无线电通信层接收的服务数据单元（SDU）可以被提供给诸如分组数据会聚协议（PDCP）层的上层通信层，而不考虑序列号。上层通信层可以处理接收的协议数据单元的重新排序。由于可以通过一个或多个IP中继器与多个设备相关的通信可以通过单个承载进行映射，所以允许在较高通信层重新排序可以减轻在供体或其它上游接入点被延迟的时候引起的延迟，以提供与下游的多个设备中的一个。在这方面，与其他设备相关的SDU可以由上层通信层处理，同时等待顺序SDU。

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： A method and apparatus for generating a cryptosync is disclosed that generates a cryptosync with the desired variability without the overhead in complexity and size of prior cryptosyncs. The cryptosync is generated from a combination of fields including fields relating to the segmentation and reassembly of the data packets at a transmitting terminal and a receiving terminal. The resultant cryptosync does not repeat during the use of a particular security key.
