Method, system and customer premises equipment for handover of speech service between different networks

Abstract

The embodiment of the invention relates to a method, a system and customer premises equipment for the handover of a speech service between different networks. The customer premises equipment comprises a handover control module for determining a speech transmission mode and performing handover between a fixed network and a mobile network, a terminal service processing module, a wireless service processing module, a cable service processing module and a central business processing module for receiving event information transmitted by the terminal service processing module or the wireless service processing module or the cable service processing module, executing operation required in the event information and transmitting the event information to control the terminal service processing module or the wireless service processing module or the cable service processing module. The method and the system can realize the automatic handover of the speech service between the wireless mobile network and the cable fixed network and reduce risks of speech transmission failures when a network breaks down.

Description

technical field [0001] The invention relates to the field of voice communication, in particular to a method, system and user premise equipment for switching voice services between different networks. Background technique [0002] With the development of communication technology, voice can be transmitted not only through the traditional Public Switched Telephone Network (PSTN), but also through Voice over International Protocol (VoIP). The data can be transmitted over the network, or can be transmitted wirelessly based on the mobile network. [0003] The way of transmitting voice through the traditional PSTN has been developed for a long time and has become relatively mature. It can provide high-quality services and has high security. However, since the voice transmission in the PSTN adopts circuit switching technology, it must be used. The fixed line is used as the carrier of voice, which will bring about high cost and complicated maintenance, and the non-movable communicat...

Problems solved by technology

[0003] The way of transmitting voice through the traditional PSTN has been developed for a long time and has become relatively mature. It can provide high-quality services and has high security. However, since the voice transmission in the PSTN adopts circuit switching technology, it must be used. The fixed line is used as the voice carrier, which will bring about high cost and complicated maintenance, and the non-movable communication terminal is a major weakness of this voice transmission method

[0004] The method of transmitting voice over the network using the Internet protocol through VoIP technology is low in cost and is developing rapidly at present, but the low quality of service and low reliability are major shortcomings of this method

[0005] Based on the mobile network to transmit voice wirelessly, the communication terminal is mobile and easy to carry, but the coverage of the wireless network signal is small. When the communication terminal moves to an area where the wireless signal cannot cover, the voice transmission cannot be carried out.
