    • In a reverse link management method in a multicarrier wireless communication system, an access terminal AT sends a Reverse Link Management Message to an access network AN. The Reverse Link Management Message carries information of the reverse link that the AT dropped. The AN sends the Traffic Channel Assignment Message to AT, and assigns a new reverse carrier link according to the received the Reverse Link Management Message. The AT establishes a reverse carrier link (reverse link) based on said Traffic Channel Assignment Message and transmits data on the new reverse carrier link. According to this method, the AT can actively report the number of its containing reverse links to AN and inform the AN of the reverse links it has dropped, without further modifying other messages and steps in terminal connection process.
    • 在多载波无线通信系统中的反向链路管理方法中,接入终端AT向接入网AN发送反向链路管理消息。 反向链路管理消息携带AT丢弃的反向链路信息。 AN向AT发送业务信道分配消息,并根据接收到的反向链路管理消息分配新的反向载波链路。 AT基于所述业务信道分配消息建立反向载波链路(反向链路),并在新的反向载波链路上发送数据。 根据这种方法,AT可以主动地向AN报告其包含反向链路的数量,并通知AN丢弃的反向链路,而无需进一步修改终端连接过程中的其他消息和步骤。

    • Systems and methods for improving performance of communications over a limited-bandwidth communication link by token-based compression of messages. In one embodiment, a mobile station parses an SIP/SDP message into pieces, wherein each piece comprises a static component and a variable component. The static component comprises fixed-format data and may be intermingled with the variable component. The static component is replaced by a corresponding token. In one embodiment, the token comprises a two-byte identifier. The remaining variable component may also be compressed. The compressed message is received by an SIP proxy server that can identify the static component of each piece of the SIP/SDP message from the received token. The SIP proxy server can then replace the two-byte token with the original static component, and reconstruct the message, in which parts of the static component may be intermingled with parts of the variable component.
    • 用于通过基于令牌的消息压缩来改进有限带宽通信链路上的通信性能的系统和方法。 在一个实施例中,移动台将SIP / SDP消息解析成块,其中每个片段包括静态组件和可变组件。 静态组件包括固定格式数据,并且可以与可变分量混合。 静态组件由相应的令牌代替。 在一个实施例中,令牌包括双字节标识符。 剩余的可变组件也可以被压缩。 压缩消息由SIP代理服务器接收,SIP代理服务器可以从接收到的令牌中识别每条SIP / SDP消息的静态组件。 SIP代理服务器可以用原始静态组件替换双字节令牌,并重构消息,静态组件的哪些部分可能与可变组件的部分混合。
