SERVICE PROVISION

摘要

A system and method provide a call service features in response to call control information conveyed by a monitored bearer channel (24) in a telecommunications network. A bearer channel monitor (200) captures the call control information and relays the information to a call control application server (90). The call control application server analyzes the call control information, and provides call control instructions to a call control node (70) that operates in the telecommunications network (100) to effect the call service. The call control node serves as one or more virtual switching points (70a-c) in the network to directly control call routing without disconnecting a called (82) or calling (10) party, unless required as part of a service feature. Control from a center of the telecommunications network provides rapid and efficient call control without use of edge devices or duplication of bearer channels in the network.
