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

摘要

Evolution Data Only / Evolution Data Optimized (Evolution Data Only / Evolution Data Optimized) (EVDO) is interworking technology in a multi-protocol revision that is based on a communication system. In this method, an access terminal (AT) and an access network (AN) that performs the session configuration in the multi-protocol scenario. The AT maintains the setting indicative of all of the protocol revision supported. The AT and the AN starts the session negotiation with their sub-type to the highest protocol revision supported by the AT and the AN. As the AT sends a power increase (up Power) and UATI (Unicast Access Terminal Identifier) ​​having idle handoff request message, the protocol revision is there are two scenarios. ; EVDO (Evolution Data Only / Optimized), UATI (Unicast Access Terminal Identifier), Handoff
