First Claim
1. A call processing method, for set-up of a voice over data-packet call in a radio access network, comprising:
- establishing a packet communication session through the radio access network for a mobile station, using first radio protocol parameters;
transporting signaling for the voice over data-packet call to or from the mobile station, through the radio access network, via the established packet communications session using the first radio protocol parameters;
receiving a request for modification of at least one of the radio protocol parameters, to support the voice over data-packet call, from the mobile station;
responsive to the request from the mobile station, modifying at least one of the radio protocol parameters to support voice over data-packet call, so as to establish second radio protocol parameters for the packet communication session; and
transporting voice over data-packet communication packets through the radio access network for the mobile station, via the established packet communication session, using the second radio protocol parameters.

Abstract
Voice over data-packet protocol, for example voice over Internet Protocol (VoIP), type communications in a network providing wireless packet data service are optimized by implementation of a mobile station initiated negotiation of radio protocol parameters adapted specifically to support the voice over data-packet application. Call set-up signaling for such a call utilizes a set of parameters for radio communication defined for a normal packet data service, for example, with packet retransmission between the base station and the mobile station. The mobile station recognizes the VoIP communication. When VoIP call set-up signaling over the robust link is complete, the mobile station sends a request to the radio network to modify one or more of the radio parameters, for example, to turn-OFF the packet retransmission; to facilitate the actual communication of VoIP packets.
