Problems solved by technology

[0027] At present, the existing technology mainly focuses on the factors of network packet loss rate, signaling retransmission time interval and maximum number of retransmissions to reduce call loss, but rarely considers reducing the number of signaling entries in the call process.

Embodiment Construction

[0042] The core idea of ​​the present invention is: in the process of releasing the call, issue the number collection strategy; in the next call process, use the number collection strategy issued in the previous release call process to collect the number and complete the call process.

[0043] Specific process such as figure 2 Shown: When the access device detects that the calling user is off-hook, it will directly send a dial tone to the calling user, and collect the number according to the number collection strategy issued by the softswitch device when the call was released last time. When the received number satisfies the connection requirement of the softswitch, the connection and conversation are carried out according to the connection and conversation process in the prior art. After the call is completed, during the call release process, the softswitch device issues the number collection strategy used by the calling user in the next call to the access device, and the ac...

Abstract

The invention discloses a method for improving the success rate of call connection. The method includes the following steps: A. After the access device detects that the user is off-hook, it sends a dial tone to the user, and adopts the number collection strategy currently stored by itself to receive the number. B. When the softswitch releases the call, it sends the next number collection strategy to the access device, and the access device stores the received number collection strategy. In the method provided by the present invention, the method of issuing the number receiving strategy in the process of establishing a call is changed to issuing the number receiving strategy in the process of releasing the call. Through the improvement of this method, the call loss of the user during the call process is reduced, and the success rate of the connection is improved, especially in a network environment with poor network quality, the effect is particularly obvious.

Description

technical field [0001] The invention relates to call technology, in particular to a method for improving the success rate of call connection. Background technique [0002] In recent years, with breakthroughs in science and technology and the rapid development of Internet services, people's demand for communication services has gradually changed from voice to comprehensive demand for data, images and voice. Traditional communication networks have become increasingly unable to meet people's growing needs. Communication needs of the new network is required to provide rich voice, data, image and multimedia services. Here, only a next generation network (Next Generation Network, NGN) is taken as an example to introduce a typical call flow in the network. figure 1 It is the call flow in the NGN network carried by IP. in such as figure 1 In the shown call flow, the use of the Media Gateway Control Protocol (Media Gateway Control Protocol, MGCP) and the access device using the Ac...
