Embodiment Construction

[0022] The method for realizing a full-duplex group call in the digital trunking communication system of the present invention mainly covers the identification of the full-duplex group call in the digital trunking system, the establishment of the full-duplex group call, and the speech of the caller and the speech of the group members during the conversation. process.

[0023] see figure 1 , figure 2 and image 3 Shown, the concrete steps that realize the inventive method are:

[0024] 1) First install and establish a digital trunking communication system, and the established digital trunking communication system can realize the group call service.

[0025] 2) Identify full-duplex group calls:

[0026] A1. In the digital trunking communication system, pre-identify a certain (or some) group call numbers as a full-duplex group call type (for example: 32820900);

[0027] or

[0028] A2. When the mobile terminal (calling user MS1) initiates a group call, the call control par...

Abstract

The invention discloses a method for implementing full-duplex group calling in a digital trunked communication system. The method comprises the steps of identifying and establishing the full-duplex group calling in the digital trunked communication system; processing speaking of a calling party and group members in a calling process. When a mobile terminal subscriber in the system dials a full-duplex group calling number of a trunked system, a control channel of the trunked system allocates two idle service channels to the calling; one of the service channels is allocated to a calling subscriber and works in a full-duplex mode, so that the calling subscriber can directly speak without a speaking authorization applying process during speaking; the other service channel is allocated to the group members and works in a half-duplex mode, so that the group members need to apply speaking authorization during speaking and can speak with permission of the system; after the speaking is finished, a speaking party releases the speaking authorization. After the whole calling is finished, the two service channels simultaneously release the speaking authorization, and the advantages of a trunked private network scheduling system can be taken to the greatest extent.

Description

technical field [0001] The invention belongs to the technical field of communication, is mainly applied to a public security digital trunking communication system, and in particular relates to a method for realizing a full-duplex group call by a digital trunking. Background technique [0002] The digital trunking communication system adopts TDMA (Time Division Multiple Access) multi-slot and digital voice compression technology, which has the characteristics of clear voice, high spectral efficiency, long communication distance, strong anti-interference ability, power saving and rich voice and data service functions, etc. It can meet the wireless communication command and dispatch needs of professional user groups such as public security and fire protection. [0003] Group call is the main communication mode of the trunking dispatching system. The establishment of a talk group can enable multiple individual users to communicate and communicate in a group call through a certa...
