ABSTRACT:
The invention relates to a method for triggering re-negotiation of a session when an Access Terminal moves from one access network (source AN) to another access network (target AN) having different capabilities in high rate packet data system. According to an exemplary embodiment of the invention, the source AN is allowed to store all the protocol subtypes, protocols and applications that AT is capable of and also allowing the AT to send this information in priority order during session negotiation and hence facilitating the transfer of this information from source AN to target AN during session transfer when AT moves from one AN to another AN. An alternate embodiment is to let the AT send the protocol subtypes, protocols and applications and other AT capable information to target AN after it moves to a new AN or by letting the Rev-A capable AN query the AT's capability information and then the AT providing this information. In another exemplary embodiment, the invention includes re-negotiation by introducing a revision (like Protocol revision) information in overhead information messages that an AN broadcasts to all ATs.
