Embodiment Construction

[0020] A system architecture and process suitable for functional addressing of railway wireless broadband communication systems, the system architecture includes network functions such as wireless terminals, RAN (Radio Access Network), SSE (Service Exchange Entity) and FNE (Function Number Entity) Entities that implement the functional addressing process. In this specific embodiment, FNE (Function Number Entity) is implemented in MCPTT (Mission Critical Push-to-Talk) server, and SSE (Service Switching Entity) is implemented in RAN (Radio Access Network). Taking this as a possible implementation manner of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0021] Such as figure 1 As shown, the present invention provides a kind of functional addressing system applicable to railway wireless broadband communication system, which includes wireless terminal, RAN (Radio Access Network...

Abstract

The invention relates to a functional addressing method and system suitable for railway radio broadband communication system. The functional addressing method comprises the following steps that: a function addressing system is constructed by a radio terminal, an RAN (Radio Access Network), an SSE (Service Switching Entity) and an MCPTT (Mission Critical Push to Talk) server; a use A dials a function number, the radio terminal accesses RAN transmission, and the SSE performs recognition and launches a functional addressing request to the MCPTT server; the MCPTT server inquires whether the dialedfunction number is valid or not; the MCPTT server checks whether a call is authorized or not through an access matrix; if the call is not authorized, the call is released, and a corresponding releasecause is provided; the MCPTT server finds an MC ID corresponding to the dialed function number for translating the function number; the MCPTT server accesses the RAN through the radio terminal for paging to obtain current position information of a plurality of MC IDs corresponding to the dialed function number, and compares the current position information with a domination range of a calling user; and the MCPTT server selects an MC ID in the domination range and sends a communication link connection establishing command, and the RAN selects a route and connects the call to a called user B.

Description

technical field [0001] The invention relates to a function addressing method and system, in particular to a function addressing method and system suitable for railway wireless broadband communication systems. Background technique [0002] GSM-R (Global System for Mobile Communications-Railway) is a railway communication method widely used at present. It has a strong standard communication system foundation, good adaptability to railways, continuous technology development and cooperation among many manufacturers, and Successful commercial applications, etc., fully demonstrate the maturity and reliability of the GSM-R system. With the continuous development of railway transportation business, the GSM-R system has shown many limitations, it is difficult to realize the carrying capacity of many current railway services, and it cannot meet the higher communication needs of production and passengers. With the continuous development and progress of civilian wireless broadband tech...
