Embodiment Construction

[0018] Such as figure 1 The shown method for realizing simplex communication based on a mobile terminal has the following steps: 1) The mobile phone user dials the target number to initiate a call, and the public network switch transfers the call path to the value-added platform according to the configuration. 2) After the called party answers and answers, the trunk module establishes the connection of the voice path, obtains the trunk time slot for connection, and establishes the corresponding call channel through the switching module to initially initiate a one-way voice exchange from the calling party to the called party. 3) The user presses the "Listen / Talk" button on the mobile terminal, and the mobile phone software module simulates the button and sends a DTMF button signal to the value-added platform. 4) The DTMF module detects the button signal corresponding to the relay time slot in real time. When the DTMF module receives the button signal, it obtains the button rela...

Abstract

The invention relates to a method for implementing simplex communication based on a mobile phone terminal. Currently, when an interphone is in conversation, the voice thereof is unidirectional and few resources are occupied, however, the definition of the voice is relative poor, and signals can be easily interfered during conversation, so the conversation quality is poor. The invention provides the method for implementing the simplex communication based on the mobile phone terminal. The method is as follows: the mobile phone terminal dials a target number to start calling, and then a public network exchanger receives a calling signaling so as to forward a speech channel to an increment platform; after a called response is answered, a relay module builds speech channel butt and sends a butt time slot channel to an exchange module, and then the exchange module builds initial one-way voice exchange from calling to incoming call; a user presses a listen/speak key on the mobile phone terminal, a mobile phone software module simulates the key to transmit a dual-tone multifrequency (DTMF) key signal to the increment platform; a DTMF module monitors the key signal corresponding to the relay time slot in real time and analyzes whether the key signal is a simplex communication key signal; and after the key is matched, and the exchange module finds out the corresponding relay time slot and changes voice direction, the simplex communication between the mobile phone terminals is realized.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method for realizing simplex communication based on a mobile phone terminal. Background technique [0002] When the walkie-talkie is talking, its voice is one-way, which takes up less resources, but its voice clarity is poor, and the signal is more likely to be interfered during the call, resulting in poor call quality. As we all know, when the existing mobile phone is talking, its voice is bidirectional, that is, the sending and receiving of its voice is a full-duplex mode and can be carried out simultaneously. If the mobile phone can implement simplex calls, the mobile phone application in the voip network can save bandwidth, improve voice clarity, and reduce the probability of signal interference in narrowband network applications. Contents of the invention [0003] The purpose of the present invention is to provide a method for implementing simplex communication bas...
