Embodiment Construction

[0015] Specific embodiments of the present invention will be described below with reference to the accompanying drawings. In order to provide a comprehensive understanding of the present invention, many details are described below, but it will be apparent to those skilled in the art that the present invention can be practiced without these details.

[0016] refer to figure 1 and figure 2 , an intercom system for air-interface frequency writing of DMR mobile stations, including a console 1, a trunking base station 2 and several mobile stations 3. Among them, the console 1 and several mobile stations 3 communicate with the trunking base station 2, the console 1 sends control signaling to the trunking base station 2, and the trunking base station 2 uses the modified DMR air interface protocol to perform frequency point or grouping of several mobile stations 3. No. parameter configuration.

[0017] refer to figure 1 and figure 2 , the method of using the above-mentioned int...

Abstract

The invention provides a DMR mobile station air interface frequency writing method and system, which relate to the field of intercom systems, and the air interface frequency writing method approximately modifies an existing DMR air interface protocol to a certain extent to enable the DMR air interface protocol to carry configuration parameters of frequency points or group numbers. Then the consoleof the intercom system carries out frequency point or group number parameter configuration on a plurality of handsets in the system by using the modified DMR air interface protocol through the cluster base station, thereby realizing the purpose of carrying out air interface frequency writing on the handsets in a remote and wireless mode.

Description

technical field [0001] The invention relates to the field of intercom systems, and more specifically refers to a method for writing frequency over the air interface of a DMR hand station. Background technique [0002] As a type of terminal of the walkie-talkie system, the mobile station generally needs to configure the channel frequency point and call group setting through the serial port or Bluetooth before use. Among them, the serial port is limited to wired connection, while Bluetooth is wireless transmission, but the transmission distance is limited, it is extremely inconvenient to operate, and only one-to-one setting updates can be performed. [0003] For the mobile stations under the trunking system, the present invention can modify the existing air interface DMR protocol to a certain extent, and can support the mobile stations that are turned on and registered into the system, and the frequency of each mobile station is performed through the network management or disp...
