A SYSTEM AND METHOD FOR INTER-WORKING IN A MULTI PROTOCOL REVISION BASED EVOLUTION DATA ONLY/EVOLUTION DATA OPTIMIZED (EVDO) COMMUNICATION SYSTEMS

摘要

A system for the interworking in the multi-protocol revision based on evolution data only/evolution data optimized communication systems and a method thereof are provided to avoid the session negotiation in case base values are used for all sub-types. The session configuration is performed by an access terminal(AT) and access network(AN). The establishment of indicating all protocol revisions that the AT supports is maintained by the AT. By using a sub-type corresponding to the maximum protocol revision supported by the AT and AN, the session negotiation is performed by the AT and AN. By using power up and idle handoff procedures, the AT transmits a unicast access terminal identifier request message including the protocol revision.
