Call processing method and system for radio local loop user in next generation network

Abstract

This invention relates to a call processing method of wireless local loop network users in the NGN including the following steps: a wireless access controller firstly sends an establishment call of setting up a call request to a soft communication equipment, which sends back the information to confirm the establishment to the wireless access controller and before wireless controller sends out the called numbers, soft communication equipment sends out a request to media gateway test the number to request media gateway to be ready for the test preparation, normal call will be established when media gateway detects the called phone number. The invention also provides a next generation wireless local loop network user processing system.

Description

technical field [0001] The present invention relates to the next generation network (NGN, Next Generation Network) technology, in particular to a call processing method and system for wireless local loop users in the next generation network. Background technique [0002] The next-generation network is a service-driven network. It adopts a comprehensive, open, and integrated network architecture. Through the complete separation of service and call control, and complete separation of call control and bearer, it realizes a relatively independent service system and makes services independent of the network. . During the interconnection and use of next-generation network equipment and Radio Access Controller (RAC, Radio Access Controller) equipment, in the case of in-band numbering, it often occurs that the first few numbers of the user dial are missing, resulting in call failure, especially in It is especially obvious in the case of a modem (Modem) data interworking function (I...

Problems solved by technology

However, after receiving the Allocation Complete message sent by the RAC, the softswitch notifies the media gateway (under the NGN architecture, the number detection is usually completed by the media gateway) to detect dialing on this circuit, so Called number may be generated

In the figure, there is a time difference between the point where the RAC starts sending numbers and the point where the media gateway starts to detect the dial. During this period, the number reported by the RAC device to the media gateway will be lost, resulting in the phenomenon of missing called numbers.
