Problems solved by technology

However, if AWI signaling is used to control the terminal's sound device, there will be a possibility that the AWI message will be lost on the air link Um interface, which will cause the sound device to not be turned on, and thus the voice cannot be played.

Embodiment Construction

[0019] Below, refer to the attached Figure 1~2 Describe in detail the method and device for controlling the sound playback device during the trunking terminal call process of the present invention.

[0020] Such as figure 1 As shown, the method for controlling the sound playback device in the cluster terminal call process of the present invention includes the following steps:

[0021] Step 100: The terminal receives the frame and judges the attribute of the frame. When the attribute of the frame is a voice frame, it performs voice broadcast; when the attribute of the frame is a data frame, it does not perform voice broadcast.

[0022] Wherein, in step 100, the attribute of the frame may be judged according to the frame header and the frame tail. This is based on the fact that the larger the length of the data frame, the larger the value indicating the size of the frame in the frame header, and the control information in the frame header of the data frame includes the packet...

Abstract

The invention provides a method and device for controlling a voice playing device in a call process of cluster terminals, wherein the method comprises the following steps of: receiving a frame by a terminal, judging whether the attribute of the frame is a voice frame or a data frame, when the attribute of the frame is the voice frame, playing voice, and when the attribute of the frame is the data frame, not playing the voice. The invention realizes the control of the digital cluster terminal voice playing device through judging the frame attribute, solves the problem of voice loss caused by an AWI (Alert with Information) signaling loss, and has no adverse effect to the standby time and the use time of the cluster terminals.

Description

technical field [0001] The invention relates to the field of digital trunking communication, in particular to a method and device for controlling a sound playing device during a call of a trunking terminal. Background technique [0002] Digital trunking communication system is a mobile communication system applied to group dispatching and command communication. The system is mainly used in the field of professional mobile communications, such as government departments, military, police, railways, water conservancy, civil aviation and steel logistics and other industries. The trunking communication is a half-duplex communication mode, and the communication is performed in a push-to-talk (Push to Talk, PTT) manner. In the digital trunking system, the speaking right of the terminal is notified and controlled through the system sending forward forward information-carrying Alert (Alert With Information, AWI) signaling. The terminal controls the sound playback device through the...
