Embodiment Construction

[0043] In order to make it easier for those skilled in the art to understand and realize the present invention, the embodiments of the present invention are described in conjunction with the accompanying drawings.

[0044] like figure 2 As shown, only half of the network entities participating in the call are drawn in the figure, and this half of the network entities may be the calling part or the called part. When the UE is in the idle mode and the user initiates a half-duplex voice call, the half-duplex voice call setup procedure is started. Refer below figure 2 Describe the process of establishing a half-duplex voice call in detail.

[0045] Step 1. Establish a call control process. In the call control flow, the bearer capability (bearer capability) information element in the existing call control message is extended so that the information element can represent a half-duplex voice call. When the user terminal initiates a half-duplex voice call, the MSC Server can fin...

Abstract

The invention discloses a method for realizing half-duplex communication, comprising: establishing a control plane bearer between a calling user terminal and a called user terminal; The user plane bearer used to transmit control frames; the calling user terminal performs half-duplex communication with the called user terminal. The invention also discloses a half-duplex communication system, which includes: user terminal, wireless network controller, mobile switching center server, media gateway and half-duplex communication controller. According to the invention, the half-duplex CS domain voice call can be realized in the WCDMA network. Increase the types of services used by users and create more income for operators.

Description

technical field [0001] The present invention relates to a communication technology, in particular to a method and system for realizing half-duplex communication. Background technique [0002] In conventional communication, there are usually the following modes: simplex, half-duplex and full-duplex. It works as shown in the table below. [0003] -------＞ -------＞ -------- A--------B A----------B A---------B ＜-------- Simplex half duplex full duplex [0004] As can be seen from the above table, if at any moment in the communication process, information can only be transmitted from one party A to the other party B, it is called simplex. If at any time, information can be transmitted from A to B, and can be transmitted from B to A, but there can only be transmission in one direction, which is called half-duplex. If at any moment, two-way signal transmission from A to B and B to A can exist on the line at...
