Abstract

The invention discloses a system for realizing a double mode vehicular terminal and a method thereof, which are combined with the characteristic of a cross-site coverage way. A mobile terminal of a locomotive platform adopts a double mode way, and is connected with a main layer network and a back layer network at the same time respectively, and selects a better signal transmission channel according to level, quality and other performances of a received signal so as to achieve the aims of sufficiently using wireless resources of the double-layer network and improving the transmission reliability, thereby solving the problem that a weak field on an overlap region between two adjacent base stations in the main layer easily causes communication interruption when cell switching is carried out in the main layer in the prior art.

Description

technical field

[0001] The invention relates to a method for realizing a dual-mode vehicle-mounted terminal, in particular to a method for realizing a dual-mode vehicle-mounted terminal based on a GSM-R interweaving active and standby double-layer network mode, and belongs to the field of digital dedicated mobile communication for high-speed passenger dedicated lines GSM-R railways. Background technique

[0002] GSM-R (GSM for Railways) system is a comprehensive dedicated digital mobile communication system specially designed for railway communication. It is based on the advanced voice call functions (such as group call, broadcast call), multi-priority preemption and forced demolition services of the GSM Phase2+ standard protocol, and adds functions such as location-based addressing and function addressing, and is suitable for railway communication special It is the need of railway special dispatching communication. The GSM-R system mainly provides voice communication funct...
