Method for realizing transform of conventional telephone exchange network to younger generation network and transition network

Abstract

This invention relates to a method for reforming a traditional public phone exchange net to the next generation and its transition network. A next generation soft exchange gateway replaces the exchange in a public exchange phone net (PSTN) network and remains the TDM transmission network between the original exchange to make the control flow based on IP network and the medium flow still on the TDM transmission network to be switched to IP network to realize transition from PSTN to NGN.

Description

Technical field

[0001] The present invention relates to the field of communication technology, in particular to a method for implementing network transformation from a traditional PSTN (Public Switched Telephone Network) network to an NGN (Next Generation Network) and a corresponding transition network. Background technique

[0002] The transition from the traditional PSTN (Public Switched Telephone Network) telephone network to the NGN network based on the IP Internet has been a generally accepted view in the industry. Under the NGN architecture, the control layer and the access layer are separated, and based on IP network bearer services, there are great improvements in scalability, capacity, and services. In the current PSTN traditional network has a considerable scale, how to ensure that there will be no impact on the business during the transition has become a common concern for operators and equipment suppliers.
