摘要： A system and method for managing call affiliation in a communication system having a plurality of communication units. When a public call announcement is initiated, a broadcast data message is transmitted to the communication units identifying a public announcement talkgroup for the call. Upon receiving the broadcast data message, each of the communication units waits a random amount of time before attempting to affiliate to the public announcement talkgroup. At the same time, each communication unit also monitors other messages on the control channel. Each communication unit joins the public announcement talkgroup upon the first of either (1) receiving an affiliation grant in response to an affiliation request transmitted by the communication unit, or (2) detecting an affiliation grant being transmitted to a different communication unit attempting to affiliate to the same talkgroup.

摘要： A method is disclosed that includes sending (304) a first full header from a source compressor (106) to a destination decompressor (112) wherein the source compressor and the destination decompressor are a part of a symmetrical configuration. An IP packet including the full header is compressed into a first compressed header (310) based on the context established in the first full header. The first compressed header is sent (312) from the source compressor to the destination decompressor. The compressor receives (322) a second full header from the destination compressor wherein the second full header indicates that the destination decompressor did not receive the first full header. The second full header can include a modified field or has an incremented generation identification. The source compressor sends (336) another full header to the destination decompressor.
摘要翻译：公开了一种方法，其包括将来自源压缩器（106）的第一完整报头（304）发送（304）到目的地解压缩器（112），其中源压缩器和目的地解压缩器是对称配置的一部分。基于在第一全标头中建立的上下文，包括完整报头的IP分组被压缩成第一压缩报头（310）。第一个压缩报头从源压缩器发送（312）到目标解压缩器。压缩器从目的地压缩机接收（322）第二个完整报头，其中第二个完整报头指示目的地解压缩器没有接收到第一个完整报头。第二个完整报头可以包括一个修改的字段或者具有递增的生成标识。源压缩器将另一个完整报头发送（336）到目标解压缩器。

摘要： A method and apparatus for maintaining communications between a mobile computer and a mobile subscriber unit is disclosed. The method and apparatus comprise determining whether a connection is available between the mobile subscriber unit and a radio communications system. If a connection is available, then the method and apparatus include retrieving a first IP address for the mobile computer from the radio communications system. Then, the method and apparatus comprise caching the first IP address in the mobile subscriber unit for use by the mobile computer. Finally, the method and apparatus include utilizing the first IP address even if the radio communications system is unavailable and updating the first IP address with a second IP address obtained from the radio communications system when the radio communications system is available.
