Abstract:
1. A method of accessing a service node from a terminal disposed in an integrated telecommunications network having a Voice-over Internet Protocol (VoIP) network portion and a cellular network portion, wherein the terminal is located inside the VolP network portion, the method comprising the steps of: providing an interface module disposed between the service node and the VoIP network portion; incorporating at least one detection point (DP) in a call control process residing in a Session Initiation Protocol (SIP) entity, wherein the DP is maintained in a user profile repository and wherein the DP further operates to pass control to a service access server when the call control process encounters the DP; determining, by the service access server, if a service needs to be executed; if so, sending a service request from the service access server to the service node through the interface module for service execution; receiving, in the service access server, a result from the service node responsive to the service request; and passing the result from the service access server to the call control process.
