Abstract

The invention discloses a method and device for base station energy-saving operation in a high-speed rail private network. The method comprises the steps that train number information reported by communication equipment in a current high-speed rail train is received, and the moving direction of the current high-speed rail train is determined according to the train number information and a train number information list stored in advance; according to the moving direction of the current high-speed rail train and a neighbor cell list stored in advance, an original service base station needing to be closed and a target base station needing to be opened are determined; a base station closing command is sent to the determined original service base station, and a base station opening command is sent to the determined target base station; when the base station closing command corresponding to all received base station opening commands is received and the current state is an activated state, the activated state is switched to a dormant state. Compared with the prior art, the method and device for base station energy-saving operation in the high-speed rail private network not only can save electric power resources but also can reduce interference of the high-speed rail train for public networks near a high-speed rail line.

Description

technical field [0001] The present application relates to mobile communication technology, in particular to a method and device for energy-saving operation of a base station in a high-speed rail private network. Background technique [0002] The public mobile communication network (abbreviation: public network) does not provide services exclusively for users in high-speed rail trains. For example, the existing GSM mobile communication network can only provide services for users whose moving speed does not exceed 250 km / h. When users When the mobile speed exceeds this threshold, if the existing public network networking method is still used, phenomena such as multipath delay, Doppler frequency shift, penetration loss, and fast switching will occur, which will seriously affect user Call quality in high-speed trains and user experience in using communication services in high-speed trains. [0003] The high-speed railway communication network (abbreviation: high-speed railway p...
