Problems solved by technology

[0007] Solution 2: The Chinese patent application with publication number CN109362060A "A Method and System for Function Addressing Applicable to Railway Wireless Broadband Communication System" can realize function addressing services, but there are the following technical problems: (1) function addressing The addressing service also involves a series of related services of the user function number (for example, registration, cancellation, query, forced cancellation, etc.), but there is no description of the related services; (2) its functional addressing service is provided by MCPTT (key task Push-to-talk) server performs access matrix verification and number translation. However, when the MCPTT server is deployed, two sets (active and standby configurations) are deployed for each railway bureau. If the functional addressing service is handled by the MCPTT server, the user Each registration / deregistration of a function number requires 18 MCPTT servers of the railway bureau for data synchronization, which will increase signaling overhead and system complexity

Abstract

The invention discloses a method for realizing a railway 5G private network function addressing service, which can realize services such as function number registration, logout, query, forced logout, function addressing, position-based call restriction and the like on the basis of a railway 5G private network by setting a 5G-IN device shared by the whole road and carrying out SIP (Session Initiation Protocol)-based interaction with MC (Media Core) equipment of a core network of each railway bureau group company. And the working efficiency of railway dispatching and commanding personnel is improved.

Description

technical field [0001] The invention relates to the technical field of railway communication, and in particular, to a method for realizing the function addressing service of a railway 5G private network. Background technique [0002] With the continuous development of intelligent high-speed railways in my country, the demand for new communication services of high-speed railways continues to emerge and become increasingly urgent. The contradiction between the GSM-R carrying capacity and the service requirements of the railway-specific mobile communication system has become increasingly prominent, and it is no longer suitable for the mobile communication needs of the development of intelligent railways under the new situation. In July 2020, China National Railway Group determined 5G as the technical standard of the new-generation railway mobile communication system, and started the research on railway 5G private network technology, system standards, and system equipment. [0...
