Communication controlling system based on No.7 signalling network, method and service controller structure thereof

The invention relates to a No.7 signaling network-based communication control system and method and the service controller structure thereof. And the system comprises several service controllers and service management servers connected to the No.7 signaling network, and the service controller applies processor technique and dispersive data list technique to communication network, and skillfully uses message transfer ability and inherent high-reliability characteristics of the No.7 signaling network to provide two signaling link access modes to implement inquiring and executing service logics of memory service data list: traditional signaling point-possessing signaling terminal mode and no-signaling point signaling conversion mode, implementing high efficiency handling and transfer of signaling information. And the invention breaks through the limit of traditional switching and intelligent network techniques, both able to be independent of the active communication network and implement in scale the services, such as user service authentication, detailed bill accounting, number upgrading and number carrying, and possessing all interfaces and characteristics of NGN data sublist and HLR.
