Problems solved by technology

[0006] 2) The one-time investment cost is too high, and there will be a long-term payment burden if the wired link is leased
[0007] 3) There are often no wired resources in the base stations of conventional communication systems, so it is difficult to optimize the network
[0008] 4) In an emergency situation, an emergency communication command vehicle is required, and it can only rely on wireless links to communicate with the command center

Embodiment 1

[0075] Example 1: Cluster call routine

[0076] 1) The trunking user 200 initiates a call to a regular user, generally a special group such as 900.

[0077] 2) After the trunking controller judges that the calling purpose is a regular user, it notifies the trunking base station switch to automatically call 13501234567.

[0078] 3) Through the GSM or CDMA network, the networker immediately picks up the hook after detecting the call, and gets through the voice link to the regular relay station, and the trunking user and the regular user can talk.

[0079] The workflow of each module of the networker is as follows (see Image 6 ):

[0080] A. The GSM / CDMA-SIM card transmits the call information to the MCU control module through the GSM / CDMA interface module after detecting the incoming call to the cluster;

[0081] B. The DTMF transceiver module is notified by the MCU control module, and a ringing tone is issued to notify the conventional mobile station and the speaker of the ...

Embodiment 2

[0088] Example 2: Conventional Call Clustering (see Figure 7 )

[0089] 1) The user dials the wired access telephone of the trunking base station (eg 51288221) through the mobile station.

[0090] 2) Through the DTMF transceiver module, the MCU control module collects the call number 51288221 initiated by the conventional mobile station, then sends the off-hook command to notify the GSM / CDMA interface module to go off-hook, and sends the call command command of 51288221 to the GSM / CDMA-SIM card. Dial 51288221, and the corresponding call status and outgoing number will be displayed on the LCD display module, and wait for the GSM / CDMA interface module to answer successfully.

[0091] 3) When the trunking base station switch detects an incoming call, it will automatically go off-hook and play a prompt tone, "Please dial the trunking number".

[0092] 4) The regular user types in the target cluster number such as 200 according to the prompt tone.

[0093] 5) The trunking base ...

Abstract

The invention discloses a networking device for realizing intercommunication between common and trunking communication systems based on GSM / CDMA, wherein, a common networking device is designed for networking the current common communication system and the trunking communication system through GSM / CDMA link. The common communication networking device comprises: an MCU control module, a PC communication module, a host computer control software module, a DTMF transceiver module, a GSM / CDMA interface module, a voice link module, a conversional station interface communication module, and an EEPROM memory module. The method is a technique for networking between a trunking and a common communication systems; when a conversation is carried out between two parties, number of the other person is called by trunking or by common systems; networking between the trunking communication system and the common communication system is realized by means of a wireless link provided by a GSM / CDMA public mobile communication system.

Description

technical field [0001] The invention belongs to a communication product and is mainly used in the field of public security communication, in particular to a networker based on GSM / CDMA to realize intercommunication between conventional and cluster communication systems. Background technique [0002] The trunking communication system is a special dispatching mobile communication system that shares wireless channels. It adopts the multi-channel sharing and dynamic channel allocation technology in modern communication, and has dispatching functions such as individual calls, group calls, and broadcast calls. The establishment is fast, the users have different priorities, the call time is limited, and it has the function of remote death and resurrection, which is very suitable for the use of the public security system. At present, the public security departments of various cities have built 350M trunking communication systems. [0003] A conventional communication system is a sin...
