Problems solved by technology

If the called party has answered but the IP bearer has not been established or the IP bearer fails to be established eventually, the calling and called users cannot hear each other's voice, and the billing has already started at this time, and it will also lead to abnormal disconnection , reducing the call quality, reducing user experience satisfaction, and causing economic losses to users

Embodiment Construction

[0113] The core idea of ​​the present invention is: MSCe sends ringing information to called BSC after detecting that the bearer of this call is established, and then called BSC notifies called terminal to ring.

[0114] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0115] Figure 5 For the call flow diagram provided by the present invention under the softswitch architecture based on IP bearer, such as Figure 5 As shown, the specific steps are as follows:

[0116] Step 501: MSCe receives a call establishment request message, and sends an add endpoint message to MGW.

[0117] The call establishment request message may be an intra-office call establishment request message for establishing an intra-office call, or an inter-office call establishment request message for establishing an inter-office call.

[0118] If the Add Endpoint message is used to apply for an IP endpoint to establis...

Abstract

A calling method over IP supporting, includes: the MSCe sends a ringing message to the called BSC after it has detected that the connection for this call has been set up; and then the called BSC informs the called terminal to ring. A calling system over IP supporting, includes: a MSCe, a MGW and a called BSC. A MSCe includes: a module for requesting an IP address and a module for transmitting the ringing message. The present invention enables the called terminal not to ring until the connection for this call has been set up, avoids the situation that the calling party and the called party can not hear each other before the connection has been set up, and prevents the unusual call drop, so as to improve the users' pleasure. Also, present invention avoids to charge before the connection has been set up, thus reducing the users' cost.

Description

technical field [0001] The invention relates to the technical field of call communication, in particular to a call method based on Internet protocol bearer. Background technique [0002] In the traditional circuit domain network architecture, the Mobile Switching Center (MSC) and the Base Station Control Center (BSC) directly use Time Division Multiplexing (TDM) circuit connections to carry voice channels. After adopting the softswitch structure, control and bearer are separated, and MSC is divided into two parts: Mobile Softswitch Center (MSCe) and Media Gateway (MGW). There are two basic bearer media in softswitch: TDM-based circuit link channel and Internet Protocol (IP)-based real-time transport protocol (RTP) media flow. When the IP network is used to bear the weight, the original voice carried by the TDM is transmitted through the IP bearer network. [0003] figure 1 It is an architecture diagram of the softswitch based on IP bearer, such as figure 1 As shown, the ...
