Problems solved by technology

[0003] The existing technology realizes the judgment of the driving direction by combining the frequency offset information reported by the base station (NODEB) and the antenna configuration direction when judging the driving direction of the high-speed rail. However, this technology has high requirements for on-site configuration and requires a large number of antennas. Configuration, operation is difficult, and the accuracy is not high

Abstract

The invention provides a method for determining the running direction of a high-speed train and network-side equipment. The method comprises the following steps that: the network-side equipment receives a call admission request which is sent by a user terminal in the high-speed train, and collects the channel updating information of an on-line terminal; the network-side equipment determines the moving direction of the on-line terminal according to the collected channel updating information; and the network-side equipment determines the running direction of the high-speed train according to the moving direction. According to the moving direction of the on-line terminal, the running direction of the high-speed train can be determined, the invention is easy to implement and high in accuracy, and reliable data guarantee is provided for subsequent call admission, so the success rate of call admission is improved.

Description

technical field [0001] The invention relates to a method for judging the driving direction of a high-speed rail and network side equipment, belonging to the field of high-speed rail wireless communication systems. Background technique [0002] High-speed rail is a very fast-moving railway. If a mobile phone user in a high-speed high-speed train initiates a call access request when it is at the edge of a cell, because the speed of the high-speed rail is too fast, when the mobile phone user has not completed the access process It has already moved to another cell. At this time, the measurement has not been completed and it is too late to initiate a handover, resulting in the failure of this call access. In order to improve the success rate of call access, it is necessary to directly connect the call of the mobile phone user to the next target cell during the process of performing the access operation, and this requires distinguishing the driving direction of the high-speed rai...
