Abstract
An arrangement for compressing (20) and uncompressing (40) system set up messages between a client and a server employing Session Initiation Protocol transmits a template (200) between client (10) and server (30). A template is pre-placed (78) by clients or servers with other clients or servers. During execution time when a client requests services by connecting to a server only a minimal template (106) is transmitted from client to server. The server then reconstructs (40) the original uncompressed message.
Claims29
A message compression method comprising the steps of:
- pre-placing a message template at a far end communication system of a communication link;
- transmitting by a near end communication system a compressed message related to the message template;
- and
- producing at the far end communication system an uncompressed message.
A SIP message compression method for a mobile unit comprising the steps of:
- pre-placing a message template at a server;
- transmitting by the mobile unit a compressed message over an RF link, the compressed message related to the message template;
- and
- combining by the server the compressed message and the message template to produce an uncompressed message.
A SIP compressed message data structure comprising:
- a service request message identifier data field;
- a template on/off data field;
- a template index data field;
- and
- an additional parameters are present data field.
A message compression method comprising the steps of:
- transmitting by a communication unit a compressed message over an RF link to a server;
- and
- combining by the server the compressed message with a message template to produce an uncompressed message.
