Abstract
The present invention establishes a new protocol that supports the continuity of a single radio voice call onto a circuit switched communications system through the use of a special addressing identifier. This special identifier is called the single radio voice call identifier, and it designates the use of a single radio voice call continuity procedure for the transition to the circuit switched communication system. The applications server receives the single radio identifier and performs the transfer of the single radio voice session without the need for other address or identifier information, and also uses the single radio identifier or a new message type to initiate the correlation of parameters related to service control session establishment in later steps.
