US 8,045,521 B2 · System and method for inter-working in a multi protocol revision based evolution data only/evolution data optimized (EVDO) communication systems

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.

Dependent claims

A method for inter-working in a multi protocol revision based Evolution Data Only/Evolution Data Optimized (EVDO) communication system, comprising the steps of:

performing a session configuration by an Access Terminal (AT) and an Access Network (AN);
maintaining, by the AT, a set of protocol revisions the AT supports;
and
performing a session negotiation by the AT and the AN with subtypes corresponding to a maximum protocol revision among a set of protocol revisions supported by both the AT and the AN,
wherein the AT sends a Unicast Access Terminal Identifier (UATI) request message with protocol revisions using power up and idle handoff procedures.
