Abstract: A method for relaying an ORREQ (origination request) message from an MSC (mobile switching center) to a service specific SCP (service control point) using an HLR (home location register) first receives the ORREQ message including a service trigger indication at the HLR. A service trigger and an identifier for the subscriber are determined from the service trigger indication within the ORREQ message. A subscriber profile within the HLR is accessed responsive to the determined identifier to identify active services for the subscriber. The service specific SCP to provide the particular service associated with the service trigger of a plurality of available service specific SCPs is determined responsive to the service trigger and the active services for the subscriber. An address of the specific SCP is determined by accessing mapping logic and the ORREQ message is transmitted from the HLR to the determined service specific SCP.

Abstract: A method for providing IP network information to a network service provider receives at a voice call continuity application server an indication that a call to a mobile device has been dropped by the IP network and transmits information relating to the dropped call from the voice call continuity application server to a monitoring system of the network service provider.

Abstract: A method for selectively establishing a voice call continuity link between a mobile device and a voice call continuity application server includes the steps of receiving a request to establish a voice over IP call connection at the voice call continuity application server from the mobile device, the request including mobile device location information for the mobile device. The method determines at the voice call continuity application server whether the voice call continuity link is needed between the voice call continuity server and the mobile device responsive to the mobile device location information within the request and network location information stored within a database associated with the voice call continuity application server. The method establishes the voice call continuity link between the mobile device and the voice call continuity application responsive to a determination that the voice call continuity link is needed.
