Method and system for realizing telephone dialing in session initiation protocol integrated access device (SIP IAD) and device

Abstract

The embodiment of the invention relates to a method and a system for realizing telephone dialing in a session initiation protocol integrated access device (SIP IAD) and the SIP IAD. The method for realizing the telephone dialing in the SIP IAD comprises the following steps of: sequentially receiving numbers dialed by a calling user; and sequentially transmitting a number reporting message to soft switch equipment to report the received numbers dialed by the calling user figure by figure according to a figure-by-figure number reporting figure chart, so that the soft switch equipment performs number matching according to the received numbers to further realize the initiation of a call from the calling user to a called user, wherein the number reporting message carries figure-by-figure numbers dialed by the calling user. The soft switch equipment can timely perform the number matching, the call is initiated to the called user after the number matching succeeds, and the calling user is not required to dial '#' as well as wait for a long time, so the user experiences are improved, and the degree of satisfaction of the user is increased.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to the telephone dialing technology under the SIP IAD. Background technique [0002] In the (Next Generation Network, NGN) next-generation network, the terminal network device that connects voice and data to the packet core network is usually called (Integrated Access Device, IAD) integrated access device, and IAD provides (Foreign Exchange Office , FXS) peripheral exchange office interface, (Foreign Exchange Subscriber, FXO) peripheral exchange user-side interface and (Internet Protocol, IP) Internet protocol interface, so that the user terminal connected under the IAD can choose to access the IP network or traditional ( Public Switched Telephone Network, PSTN) public switched telephone network. The protocols supported by the IAD include (Session Initiation Protocol, SIP) session initiation protocol, H.248, (Media Gateway Control Protocol, MGCP) media gateway control protoco...

AI Technical Summary

Problems solved by technology

[0005] The inventor discovered during the invention that in the prior art, the SIP IAD will not immediately report the number to the softswitch during the number receiving process, there is a certain delay, and the speed of initiating a call is slow. If you want to speed up the call, you need to Dial "#" after the number, and the number will be reported to the softswitch immediately, resulting in a different experience and habit of dialing from traditional PSTN calls (no need to dial "#"), especially For some users who do not often use SIP IAD, because they are not used to dialing the "#" number, there is no response for a long time after dialing the complete number. Unusable, seriously affecting user satisfaction and experience
