Embodiment Construction

[0074] The present invention will be further described below in conjunction with accompanying drawing.

[0075] attached figure 2 It is the system architecture of the LTE (Long Term Evolution, long-term evolution) network system in the CBTC system. In this system architecture, a dual-network structure is used. In this embodiment, each RRU (radio remote unit) will be defined as a LTE cells. attached image 3 It is a schematic diagram of LTE cell wireless coverage.

[0076] see figure 1 , the wireless network handover control method of CBTC system of the present invention, comprises the following steps:

[0077] Step S1, LTE cell measurement parameter configuration:

[0078] Perform measurement configuration on the LTE base station (eNodeB) on the network side, and configure the following information for each LTE cell:

[0079] 1) Neighboring LTE cells of the current LTE serving cell;

[0080] 2) The measurement objects are the current LTE serving cell and neighboring LT...

Abstract

The invention discloses a wireless network handover control method of a CBTC system, comprising: an LTE base station configures measurement parameters for an LTE cell; defines an LTE cell communication area; establishes communication between a TAU and a VOBC; and the TAU performs LTE cell measurement and sends the measurement result To VOBC; VOBC obtains the handover control information according to the measurement results and sends it to TAU; TAU processes the handover control information and reports the measurement report to the LTE base station; after receiving the measurement report, the LTE base station triggers a handover decision. If the handover decision is established, the LTE base station sends the TAU Send the switching command; TAU executes the switching after receiving the switching command; VOBC monitors the switching result. It solves the problem that the LTE network communication system and the conventional signaling system in the existing CBTC system are relatively independent, and the existing technology does not consider the cooperation and cooperation between the signaling system and the network communication system.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a wireless network switching control method of a CBTC (communication-based automatic train control system) system. Background technique [0002] LTE wireless communication has been more and more used in CBTC system, becoming the main system of vehicle-to-ground communication, providing wireless network coverage, but LTE network communication system is an integral part of CBTC system, and it is different from other subsystems in CBTC system Relatively independent, other subsystems (such as VOBC) in the signaling system cannot know the relevant information of the LTE network. The LTE network controls data transmission according to its own configuration. The existing technology does not consider the interaction and cooperation between the data communication system and the signaling system. [0003] The LTE network uses cells for network coverage of lines, and uses different tra...
