Abstract:
Interworking in a multi-protocol revision based Evolution Data Only/Evolution Data Optimized (EVDO) communication system is described. In this scheme, an access terminal (AT) and an access network (AN) perform session configuration in multi-protocol scenarios. The AT maintains a set indicating all the protocol revisions it supports. The AT and AN start their session negotiation with the subtypes corresponding to the highest protocol revision supported by AT and AN. There are two scenarios in which AT sends the Unicast Access Terminal Identifier (UATI) request message with protocol revisions: power up and idle handoff.
