METHOD AND APPARATUS BY WHICH A UE STARTS COMPRESSION IN SIP SIGNALLING TO IMS |
摘要 |
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. |
