Problems solved by technology

[0006] The main disadvantage of the existing network reform scheme is that at the initial stage of network reform, large-scale changes to the entire transmission network are required, and it can only be operated after a relatively complete IP network that can guarantee QOS (Quality of Service) has been established.
The entire network transformation process has a high threshold and involves a wide range of areas, which brings greater risks to operators

Embodiment Construction

[0021] The following describes the present invention in further detail based on the drawings and embodiments:

[0022] In the network transformation from PSTN to NGN, if all TDM (time division multiplexing) transmission networks are replaced with IP networks at one time, the impact of the transformation will be greater. Therefore, the present invention provides a progressive network transformation method. Such as image 3 Shown. In the figure, the TDM connection that carries the voice channel is reserved between all gateways, and the call signaling is sent to the soft switch through the upstream IP channel. In this kind of networking, the TDM connection between the gateways in the softswitch domain can be configured as an intra-office intercommunication relay through data configuration, using a processing mode similar to self-loop, sharing the existing relay routing mechanism, and realizing voice channels TDM-based routing between intra-office gateways.

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. [0003] Such as figure 1 Shown is the traditional PSTN netwo...
