CALL SETUP IN INTELLIGENT NETWORK

摘要

A method and a system for reducing transmission of parameters between a mobile switching center and a service control point in a telecommunication network such as the Wireless Intelligent Network. The mobile switching center transmits a first signaling message containing only a first set of parameters to the service control point during initial call processing. In response, the service control point transmits a second signaling message to the mobile switching center indicating to the service switching point a second set of parameters required by the service control point with respect to the first signaling message. The service switching point then transmits the second set of parameters in a third signaling message to the service control point in response to the second signaling message. During subsequent call processing, the mobile switching center transmits to the service control point the first signaling message containing both the first set of parameters and the second set of parameters without requiring the service control point to again indicate to the mobile switching center the second set of parameters required by the service control point with respect to the first signaling message.
