Method of automatic extension telephone subscriber jointing in value added telecommunication service

Abstract

The invention is a method for automatic switching telephone extension service in telecommunication increment service, which is used to extend the telecommunication increment service supported by the telecommunication network to the telephone extension user at side of user's exchanger, the method includes following steps: the service platform calls the telephone exchanger according to the calling user application; the telephone exchanger responds the call, creates the voice channel of the service platform and the user exchanger; the service platform sends telephone extension number to the user exchanger through the voice channel; the user exchanger switches the call to the telephone extension user according to the extension number. The invention completes the switch between the user exchanger and the telephone extension user automatically through the service platform, it need not to change the automatic user exchanger, it is compatible to current network equipment, the investment is small, thus the telecommunication increment service can be developed to the extension side.

Description

technical field [0001] The present invention relates to a method for call processing, more specifically to a method for automatically connecting extension users. Background technique [0002] Today, based on the original basic voice services, telecom operators continue to provide various telecom value-added services to make full use of existing network resources and attract users to consume. Telecom value-added services are value-added services realized by intelligent networks or intelligent platforms, such as telephone voting services, debit card call services (300), called centralized payment services (800), wide-area centralized user exchange services, public call services, virtual Private network service (600), general personal communication service (700), etc. The intelligent network is an additional network structure set up on the basis of the original communication network to quickly provide new services. The control function can conveniently and flexibly obtain the...

AI Technical Summary

Problems solved by technology

[0004] This method has the following disadvantages: 1. It can only be effective for some extension users, and it is not economical for the enterprise to apply for value-added services for all extension users.

2. Enterprises need to apply for more phone numbers from telecom operators, which increases the cost

3. The enterprise needs to upgrade or replace the automatic subscriber switch that supports extension direct access, which will increase the investment cost of the equipment

[0007] 1. At present, not all telephone exchanges on the telecom network support Centrex. There are business blind spots in this method, and it cannot be fully compatible with existing network equipment.

[0008] 2. After being replaced by Centrex, enterprises lose their ability to directly control user switches, and some enterprises are unwilling to accept this technical solution, which makes it difficult for operators to promote their services
