Embodiment Construction

[0039] A complete networked digital trunking communication system includes two parts: terminals and system facilities. The terminals are mainly mobile stations such as mobile stations and vehicle stations; the system facilities are composed of base station subsystems, switching subsystems, network management subsystems, and dispatching subsystems. Among them, the switching, network management, and dispatching subsystems are concentrated in the control center, while the base stations are located in different regions of the coverage area according to the planned partition coverage. Such as figure 1 As shown, the TETRA mobile station (101) communicates with the TETRA base station subsystem (103) through the TETRA air interface (121), and the PDT mobile station (102) communicates with the PDT base station subsystem (104) through the PDT air interface (122), exchanging The subsystem (105), the network management subsystem (106), and the dispatching subsystem (107) constitute the s...

Abstract

The invention discloses a method for accessing terminals of different standards in a digital trunking communication system. In the method, a protocol adaption module is added in a posting data transfer (PDT) base station; an interface from the PDT base station to a switching control centre adopts the same interface protocol as the interface from a TETRA base station to a switching control centre B1; and the protocol adaption module consists of a base station switching interface processing module, a protocol adaption layer module, a data link layer module and a physical layer module. By the method, the PDT base station and the TETRA base station can share the same switching control centre; the requirement on the compatibility of the two standards of users can be met; the PDT base station and the TETRA base station can share a network management system, namely the network management system can support the management of a TETRA network element and a PDT network element at the same time; and the PDT base station and the TETRA base station can share a scheduling platform system, namely the scheduling platform system supports the scheduling of TETRA and PDT users at the same time.

Description

technical field [0001] The invention relates to the technical field of digital trunking communication, in particular to a method for realizing mixed networking of different digital trunking systems. Background technique [0002] Mobile communication systems can be divided into public mobile communication systems and private mobile communication systems according to their nature of use. The trunking communication system belongs to a dedicated mobile communication system, which is a multi-purpose, high-efficiency wireless dispatching communication system that shares resources, shares costs, and shares channel equipment and services. In terms of network topology, the trunking communication system has a structure similar to that of the public mobile communication system: the terminal communicates with the base station subsystem through the air interface; each base station subsystem is connected to a different subsystem with switching functions, management functions, scheduling f...
