Abstract:
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.
