Multiple network connector and method of providing speech business

Abstract

Relevant multiple network connection device is added between user terminal device and circuit switchboard of PSTN network by using present PSTN network line in order to carry out transmission process for voice service in different networks. Thus, the invention provides a feasible method for new operation company, which has no resources of voice access network, to attract users in network of operation company, which has resources of access network. The new operation company can provide wideband data service and IP voice service for end users. Providing IP voice service for end users, the invention does not need to change devices and circuits of original operation company, does not need change habit of dialing up phone call at user's terminal through bypass long distance call of voice service provided by present operation company.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a multi-network connection device and a method for providing voice services. Background technique [0002] With the rapid development of IP (Internet Protocol) voice technology, all telecom operators, especially new operators, are actively expanding their business fields and improving their competitiveness by developing voice and value-added services over IP. In the process of fierce competition among various operators for customers, operators with line resources at the access layer will firmly control the line resources at the access layer, and will not be borrowed by other operators, such as PSTN networks. However, operators of wireless line resources hope to tap a group of customers by providing cheap long-distance telephone services to PSTN telephone users. That is, it is hoped that by transforming (superimposing) the telephone voice gateway or access network e...

Problems solved by technology

The emergence of this kind of IAD has solved the shortcoming of the above-mentioned technical solution to change the user's usage habit to a certain extent, however, for this kind of IAD, there is no device that can make the user's telephone set access the IAD more conveniently at present. Therefore, there is a particular need for a multi-network connection device based on the existing network wiring conditions at present, so that users can access the IAD through such a multi-network connection device, and finally realize that the user can choose the corresponding voice-providing device according to needs. business network
