    • A method (and corresponding equipment) by which a UE device (10) begins compressing messages it transmits to an SIP outbound proxy server (12) as SIP signals, including: a step (22a) in which the UE device sends a request message (22a 32a 42a) to the SIP outbound proxy server (12); and a step (23 33 43) in which the UE device analyzes a response message (22b 32b 42b) received from the SIP outbound proxy server (12) in response to the request message (22a 32a 42a) to determine a compression parameter. The request message (22a) may be an options request message and the response message (22b) would then be e.g. a 200 OK message. Alternatively, the request message (32a) may be a register message, and the response message (32b) would then be e.g. a 401 (unauthorized) message. In another embodiment, the response message (42b) is any compressed message.
    • 一种UE设备(10)开始将其作为SIP信号发送到SIP出站代理服务器(12)的消息压缩的方法(和相应的设备),包括:步骤(22a),UE设备发送请求消息 (22 a 32 a 42 a)到SIP出站代理服务器(12); 以及步骤(233343),其中所述UE设备响应于所述请求消息(22 a 32 a 42 a)到所述SIP出站代理服务器(12)接收到的响应消息(22b 32 b 42 b) 确定压缩参数。 请求消息(22a)可以是选项请求消息,并且响应消息(22b)将是例如。 200 OK消息。 或者,请求消息(32a)可以是注册消息,并且响应消息(32b)将是例如, 401(未经授权)讯息。 在另一个实施例中,响应消息(42b)是任何压缩消息。
