Data communication method, device, trunking system and repeater

Abstract

The present invention provides a data communication method, the method is executed by the repeater of the trunking system, including: the repeater receives the telephone call request initiated by the terminal; after parsing out that the telephone call request is a call sent to the public telephone network When requesting, judge whether this repeater is the proxy repeater of the terminal, if not, then inquire about the proxy repeater of the terminal, and send the telephone call request to the proxy repeater; After the confirmation response of the public telephone network sent by the proxy repeater, the repeater receives the voice data sent by the public telephone network, and establishes voice data transmission between the terminal and the public telephone network. In addition, a data communication device, a trunking system and a relay station are also provided. The above method, device, trunking system and repeater for electrical data communication can realize roaming of terminals in the whole network without high cost.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a data communication method, device, trunking system and repeater. Background technique [0002] In order to realize the real-time voice conversation between the terminal and the telephone terminal, the existing implementation scheme includes the implementation process based on third-party equipment and the conventional telephone scheme based on the SIP protocol through the Ethernet network port. [0003] On the one hand, the intercommunication between the terminal and any telephone terminal in the telephone network is realized by means of a third-party device. This solution requires the use of additional hardware devices. One side of the third-party device is connected to the end pin of the repeater, and the other side is connected to the analog phone When the terminal makes a call, enter the phone number through the keyboard and the third-party device parses it and dials ...

Problems solved by technology

[0006] However, during this process, the terminal can only make calls under the fixed repeater. Once it roams to other repeaters, it can only transmit the voice of the phone to the bound repeater through the network through the IP Internet. The air interface of the bound repeater is transmitted to the terminal, thus occupying a large amount of network resources and air interface resources

[0007] That is to say, in the existing intercommunication between the terminal and the telephone network, no matter what implementation scheme is adopted, the terminal can only use the channel resources provided by the bound repeater, which brings a very high cost, such as very high high hardware costs, a large amount of resource occupation, etc., and it is impossible to roam the entire network
