    • A Packet Data Services Node (PDSN) optionally frames user data from an Application IP packet received from a public data network (e.g., the Internet) into a Point-to-Point Protocol (PPP) frame, and encapsulates the Application IP packet or PPP frame data into one or more Generic Routing Encapsulation (GRE) frames for further transmission within a wireless communication network. The PDSN additionally inserts into each GRE frame, Application IP packet fragmentation information that indicates whether the Application IP packet or PPP frame terminates in the associated GRE frame. Other network nodes, such as a Packet Control Facility (PCF) or Base Station Controller (BSC), may interpret the fragmentation information and ascertain the boundaries of Application IP packets or PPP frames, using this information to improve network efficiency.
    • 分组数据服务节点(PDSN)可选地将从公共数据网络(例如,因特网)接收的应用IP分组中的用户数据映射到点对点协议(PPP)帧中,并且将应用IP分组或PPP 帧数据转换成一个或多个通用路由封装(GRE)帧,用于在无线通信网络内进一步传输。 PDSN另外插入到每个GRE帧中,指示应用IP分组或PPP帧是否在相关联的GRE帧中终止的应用IP分组分段信息。 诸如分组控制设备(PCF)或基站控制器(BSC)的其他网络节点可以使用该信息来解释分段信息并确定应用IP分组或PPP帧的边界,以提高网络效率。

    • A signaling method reduces bandwidth requirements and signaling delays normally associated with sending text-based signaling messages over a wireless links. An application at a transmitting endpoint generates and sends a binary-encoded signaling message, along with a binary interpreter that enables the receiving endpoint or SIP server to construct a text-based message from the binary encoded message. The binary-encoded signaling message may include references to a saved state, or to a dictionary to enable compression of the message. The signaling method can be used with any text-based signaling protocol, such as the Session Initiation Protocol, the Session Description Protocol, and the Real Time Streaming Protocol.
    • 信令方法减少了通常通过无线链路发送基于文本的信令消息相关联的带宽要求和信令延迟。 发送端点处的应用产生二进制编码的信令消息以及二进制解释器,其使接收端点或SIP服务器能够从二进制编码的消息构建基于文本的消息。 二进制编码的信令消息可以包括对保存的状态的引用,或者可以包括引用消息的压缩的字典。 信令方法可以与诸如会话发起协议,会话描述协议和实时流协议的任何基于文本的信令协议一起使用。
