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

Abstract

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.

Description

technical field [0001] The present invention relates to a communication control system, method and service controller structure based on the No. 7 signaling network, which can implement intelligent and mobile network construction without upgrading and transforming the communication and service equipment of the active network, and realize the communication service It provides key new services such as authentication triggering of user services, detailed billing, number upgrade, and number portability. Background technique [0002] In fixed and mobile communication networks, signaling is the key to business control. Signaling System No. 7 (SS7) is the most widely used signaling method. SS7 network is the core support network of the telecom network. Every call The introduction of calls and most of the new services are inseparable from the support of the No. 7 signaling network. [0003] The No. 7 signaling protocol and signaling messages are the basis for realizing communicatio...

AI Technical Summary

Problems solved by technology

People often think of intelligent network technology and HLR query response technology first, and carry out intelligent transformation of the network on the local network, but this does not get rid of the limitations of traditional switching and intelligent network technologies. Standard switches are upgraded or replaced by tandem offices. When introducing new services, the bearer network and signaling network are required to provide support in call control and signaling dialogue. The network needs to be restructured, and the business and bearer network are tightly coupled. It is still scattered in the switchboard, and additionally increases the traffic volume of the existing network. It is necessary to build a superimposed signaling network and a centralized service execution data table. The implementation of some services is also limited by the networking mode, and it is difficult to solve the investment in technology and networking Contradiction with efficiency, technology and development

Furthermore, due to the cooperation of the signaling protocol, the structure and interface of the data table, the interoperability of equipment from multiple manufacturers has also brought difficulties, which is also taboo for operators and future development.

The scale of the public communication network is huge and the system is complex. Upgrading and changing the existing network requires a large investment, high risk, and affects the quality of service. It is also necessary to consider the risk of safe operation of the centralized data table, remote redundant configuration to deal with surge traffic, and network security. development and evolution
