A method and system for providing wireless-specific services for a wireless access network includes receiving at a call agent of a wireless access network a call origination for a mobile device. Whether the device is registered on the wireless access network is determined. If the mobile device is not registered, whether the mobile device is active is determined at a mobility control function (MCF). If the mobile device is active, the call is connected to the mobile device with a call agent based on a temporary line directory number (TLDN) assigned by the MCF and passed to the call agent in an extended session initiation protocol (SIP) message.

A method and system of control signaling for a wireless access network includes receiving from a wireless access network a signaling message for a mobile device. The signaling message is in a wireless-specific format. The signaling message is converted to a native format of a call agent to generate a call agent message. The call agent message comprises wireless-specific information of the signaling message.

A method and system for providing supplementary services for a wireless access network includes downloading supplementary service triggers from a call agent to a mobility control function (MCF) for a wireless access network. Wireless-specific signaling of the wireless access network is communicated to the MCF. The MCF detects events associated with a trigger based on the wireless-specific signaling. The call agent is informed of the events by the MCF through session initiating protocol (SIP) extensions.

A computerized method of preserving stable calls during a split mode operation of telecommunications equipment includes the steps of sending a call block update message from a first side of the telecommunications equipment to a second side of the telecommunications equipment. The call block update message includes dynamic call state data on the stable call handled by the first side and stored in a call block file in the first side of the telecommunications equipment. The method includes sending a call block update acknowledgement message from the second side of the telecommunications equipment to the first side of the telecommunications equipment in response to receiving the call block update message. The above steps are repeated until all dynamic call state data in the call block file is duplicated and sent to the second side.
