Data communication method and device, trunking system, and repeater

Abstract

The invention provides a data communication method which is performed by a repeater of a trunking system, the method comprising: enabling the repeater to receive a telephone call request initiated by a terminal; when it is analyzed that the telephone call request is a call request to a public telephone network, determining whether the repeater is an proxy repeater of the terminal, if not, querying the proxy repeater of the terminal and sending the telephone call request to the proxy repeater; and after an acknowledgement response of the telephone call request transmitted from the proxy repeater is received, enabling the repeater to receive the voice data transmitted by the public telephone network and establish voice data transmission between the terminal and the public telephone network. In addition, there is provided a data communication device, a trunking system and a repeater. The data communication method, the data communication device, the trunking system and the repeater can realize the whole network roaming of the terminal without causing the 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
