Embodiment Construction

[0035] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0036] Such as figure 1 As shown, in the method and device embodiment for realizing single call or group call in the wireless voice / data system of the present invention, its method comprises the following steps:

[0037]Step S11 Generating or selecting an address code: For a voice / data system, it includes multiple independent communication terminals, and when a communication terminal initiates a call, it must have a certain calling object. These call objects may be other communication terminals set in a group, or a specific communication terminal, or all communication terminals in the system. These situations are called group call, single call and group call respectively. . In this embodiment, a communication terminal calling another specific communication terminal is taken as an example to illustrate the implementation process. For the situation that...

Abstract

The present invention relates to a method for realizing individual calling or group calling in wireless voice / data system comprising steps as follows: receiving an address code consisting of several bits which is input from outside or predetermined in a device; prior to transmitting a voice signal, modulating the address code into a radio frequency carrier signal in a digital modulation manner and sending the modulated radio frequency signal; demodulating the aforementioned radio frequency modulation signal by a device terminal which receives said radio frequency so as to obtain said address code; comparing the obtained address code with each address code to be responded and stored in this terminal one by one, and determining whether the obtained address code is identical to one of these address codes, if so, varying a squelch control signal so that a loudspeaker of the terminal produces a sound, or otherwise, maintaining the squelch. The present invention further relates to a device for realizing aforementioned method. The implementation of the method and device for realizing individual calling or group calling in wireless voice / data system of the present invention has following beneficial effects that: the method and the device have good communication effect and are capable of realizing individual calling or group calling.

Description

technical field [0001] The present invention relates to a wireless communication system, more specifically, to a method and device for realizing single call or group call in a wireless voice / data communication system. Background technique [0002] In a wireless voice / data communication system (including a separate voice communication system, a separate data communication system, and a combination of the two), due to the large number of communication terminals and the continuous increase in the coverage of a single terminal, it is necessary to The voice signal is controlled. At present, the sub-audio frequency method is usually used to realize the site selection call of the voice communication terminal, that is, when the transmitter sends the voice signal, the transmitter continuously sends out sub-audio frequency (the frequency is lower than 300 Hz) continuous signals, and these sub-audio signals are related to the audio frequency. The signals modulate the radio frequency c...
