No.7 signalling information processing device with signalling information content sevice function

Abstract

The No. 7 signaling message processing device with signaling message content service function is connected with signaling link function unit, and has one signaling message content service control module, which includes: type identifying unit for identifying the service type and message type of signaling message, content control unit for the analysis and control of the designated content, data base for storing the signaling message altering content and altering condition, data synchronizing unit for amending and synchronizing signaling message altering content and altering condition, operating and maintaining unit for operation, maintenance and detection. The present invention integrates the signaling message content service function in the amendable software mode in available telecom equipment with No. 7 message transferring and processing function to realize communication control and route selection.

Description

technical field [0001] The present invention relates to a No. 7 signaling message processing device. Specifically, on the premise of not changing the structure of the existing telecommunication network and not involving modification of the call control program, in order to implement a specific service (for example: number portability service of the telecommunication network), by Control and process the content of No. 7 signaling messages to realize communication control and routing. Background technique [0002] The No. 7 signaling protocol and signaling messages are the basis for realizing communication service control and communication routing control. Caller identity and characteristics, called address and identity characteristics, user service function characteristic indication, these specific signaling message content fields are elements for controlling communication routing, call connection and service realization. If the called address is a necessary condition for th...

Problems solved by technology

[0007] Although the above two devices do not involve modifying the existing call control program and do not change the existing telecommunication network structure, they only change the specified content of the No. 7 signaling message to achieve the purpose of controlling call establishment and routing selection. It can be serially connected in the signaling data link in an independent form, and generally requires hardware support, especially it is not easy to integrate in telecommunication equipment nodes

In this way, the signaling transmission equipment in the signaling network and its connection with the signaling data link, as well as the maintenance and management of its equipment, also increase the hardware investment.
