<p><P>PROBLEM TO BE SOLVED: To provide a session initiation protocol(SIP) method for transferring a system message to a service subscriber based on various SIP such as IM(Instant Message), PoC(Push-to-Talk Over Cellular) and MMS(Multimedia Messaging Service) and another arbitrary SIP based service to be performed by a service provider as a host. <P>SOLUTION: This system message is prepared in special formats to be transferred by a system for various purposes(charging guide, service notification, warning and instruction or the like). Those system messages include a list for mostly offerable options, and any replay from a user is required. Specific service information is transferred, and new content and a new feature tag are inserted into an existing SIP structure to receive the replay of the user so that a system message can be transferred by the SIP. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
