Calling continuing method and system based on intelligent network control

Abstract

A connection method based on intelligent network controlled call includes triggering communication service to intelligent network service platform by soft interchange device (SID) according to service settings of terminal unit corresponding to called number, connecting call to terminal unit bound with called number by SID according to logon information of terminal unit, down-sending connection message containing a calling number corresponding to calling end to SID by intelligent network service platform if said call is failure and connecting call to terminal unit corresponding to called number by SID according to said connection message. The connection system for realizing said method is also disclosed.

Description

technical field [0001] The invention relates to the technical field of call connection control, in particular to an intelligent network-based call connection method and system. Background technique [0002] "Entire network intelligence" is based on the "switch + intelligent network" equipment as the most effective voice service bearer network. It takes full advantage of the intelligent network to control the switch for call connection, and at the same time realizes real-time billing and instant display of call charges. Utilizing the powerful business processing capability and flexible business function characteristics of the intelligent network, combined with the switching and connection function of the switch, it can provide users with higher-quality business functions and services than ordinary switches and common intelligent networks. [0003] Since the intelligentization of the whole network makes full use of the design idea of ​​separating call connection and call contr...

Problems solved by technology

However, the number resources of telecom operators are limited, and users often have multiple terminals. If a number is assigned to each terminal, the resource consumption will be large, which will cause insufficient number resources of the operator;

[0020] In addition, after the user has applied for the number binding service, for example, when a calling terminal calls a fixed phone with an actual number assigned, the service control of the intelligent network will carry out the selection and connection of the terminal. Call the number, when calling the PHS terminal fails, it will continue to trigger the service control of the intelligent network, reconnect the PHS, forming a repeated trigger of the service, there is no good way to prevent the repeated trigger of the service
