Method and system for achieving functional addressing service based on MCPTT architecture

Abstract

The invention discloses a method and system for achieving the functional addressing service based on the MCPTT architecture, and the method and system are used for a scheduling command communication system. The method comprises the steps: adding an FFN function node in an MCPTT application plane, and storing the specific information, correlated with a function number, of the scheduling command communication system in the FFN function node, wherein the information comprises the correlation between the function number of a terminal and an MCPTT identification ID; enabling the terminal to achievethe registration and / or cancelling of the function number through a configuration management function of a CSC (Common Service Core) or an extension service registration process; defining a first interface between the FFN function node and an MCPTT server, wherein the first interface is used for storing and querying the related information of the function number; carrying out the interaction withthe FFN function node after the MCPTT server detects the functional addressing service in a calling process through the called function number, and obtaining a called MCPTT ID. According to the technical scheme of the invention, the method can achieve a purpose of initiating a call through the function number during a single call.

Description

technical field [0001] The present application relates to the technical field of dispatching and commanding communications, in particular to a method and system for implementing function addressing services based on the MCPTT framework. Background technique [0002] Railway mobile communication system (GSM-R), as the mainstream technology of global railway wireless communication, undertakes the important responsibility of railway train voice dispatching and train control data bearing. However, GSM-R cannot meet the needs of a large number of railway non-safety data services, such as video surveillance, passenger services related to high-speed data, train log transmission, etc.; and wireless technology is developing rapidly, and GSM, which is based on GSM-R, has gradually withdrawn from the market , the International Union of Railways (UIC) basically determined that the evolution of the next-generation mobile communication system for railways will surpass 3G, and proposed a d...

Problems solved by technology

[0023] As mentioned above, the MCPTT architecture uses the MCPTT ID to initiate a call. At present, it cannot directly support the function addressing service of LTE-R. However, due to the huge difference between the GSM and LTE network architectures as the basic technology, the intelligent network composition structure of GSM-R It cannot be directly used in the MCPTT system based on LTE technology
