System and method for reminding telephone bell echo

Abstract

The method thereof comprises: the calling side and called side make a call communication in IP network through nodes connected to each of them; when the call network of called side is at engaged condition, the server of IP network sends request message for starting the ring-back prompt function; when the server receives the request message for starting ring-back prompt function, it sets a ring-back prompt tag, and then makes circle detection for the current state of call network of called side; when the call network of called side is detected to be at idle state, it sends the ring-back prompt message to server, and further sends it to the node of calling side.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a system and method for providing a ringback prompt to a calling party during a telephone call. Background technique [0002] With the development of communication technology, the number of mobile communication users is increasing rapidly, and the frequency of people using telephones is also increasing, and the appearance of IP telephones makes calls more cheap. [0003] IP telephony is a new type of telephone system using the Internet as the transmission medium. It compresses and encodes voice signals through voice compression algorithms, and then packages these voice data according to the TCP / IP standard, and then cuts them into different data through the network. The packet is sent to the receiver. The receiving end composes these packets of voice data into a complete signal, and then sends it out through the earpiece or loudspeaker. [0004] However, with the increase in...

Problems solved by technology

[0004] However, with the increase in the frequency of people using IP phones, some common problems usually occur, such as the user who wants to call is currently not in front of the phone, or the user who wants to call is talking with someone else. Therefore, this Often the calling party can only receive a ringback tone such as "beep...beep" or prompt information such as "please wait" and "the other party is busy"

In view of the situation that the called user is not in front of the phone, the communication operator has proposed the function of voice message phone, but there is no corresponding effective solution for the problem of the called user talking with others

Therefore, usually the calling party will make a call after a few minutes, but the situation that the other party is still in the conversation often occurs, so it will take too much time and energy for the calling party to get in touch with the other party. have a certain impact on their work or life
