Method and apparatus by which a UE starts compression in SIP signalling to IMS
First Claim
1. A method by which a UE device (10) begins compressing messages it transmits to an SIP outbound proxy server (12) as SIP signals, the method characterized by:
- 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 for use in compressing messages it sends to the SIP outbound proxy server (12).

Abstract
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.

6. An apparatus used by a UE device (10) to begin compressing messages it transmits to an SIP outbound proxy server (12) as SIP signals, the apparatus characterized by:
-
means (22a) by which the UE device sends a request message (22a 32a 42a) to the SIP outbound proxy server (12);
means (23 33 43) by 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 for use in compressing messages it sends to the SIP outbound proxy server (12). - View Dependent Claims (7, 8, 9, 10)
