Method and system for VPN short number synchronous ringing

Abstract

The invention relates to a VPN short-number simultaneous ringing method, which comprises the following steps that: after receiving a call from a short number, an end-office switch queries the short number in numbers in a Centrex group; if the short number is not one of the numbers in the Centrex group, a service access code is inserted to exclude the short number, and the short number is routed to an SSP to trigger a VPN service; a VPN service platform converts the short number into a corresponding true long number and issues the long number to core network equipment; and the core network equipment queries whether the long number signs a simultaneous ringing contract and triggers a simultaneous ringing service platform to execute simultaneous ringing function if so. The method can be used for realizing other called services. The invention also relates to a VPN short-number simultaneous ringing system. The method utilizes the end-office switch to judge short-number calls and realizes call exclusion by setting short numbers of non-Centrex groups so as to trigger the simultaneous ringing service platform to realize the simultaneous ringing function, enable VPN users to use the simultaneous ringing function and prevent call missing.

Description

technical field [0001] The invention relates to the technical field of telecommunications, in particular to a method and system for simultaneous vibration of a VPN short number. Background technique [0002] Simultaneous ringing service is a characteristic service in the telecommunications network in which multiple terminals ring at the same time when they are called, or multiple terminals ring in the order preset by the user when they are called. This service binds a fixed telephone number with one or more other communication terminal numbers (such as PHS, mobile phone, fixed telephone, etc.), and when other users dial the fixed telephone number, it can follow the pre-set ringing transfer mode. Ring the user's fixed phone and multiple bundled terminals. Users who use the simultaneous vibration service only need to announce the fixed phone number to the public, and no matter how the phone numbers of other bundled terminals change, others can get in touch with the user by di...

AI Technical Summary

Problems solved by technology

[0003] Simultaneous vibration service is a very distinctive service in the telecom network, but it is generally not open to virtual private network (Virtual Private Network, referred to as VPN) users, because VPN users make intra-network calls by dialing short numbers. In order to provide users with a better experience, VPN users are generally made into Centrex users at the end office, and for the Centrex group, the end office directly handles calls within the group without going through various service platforms such as VPN. Therefore, the simultaneous ring function cannot be provided for such calls
