Embodiment Construction

[0036] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0037] like figure 2 As shown, the present invention provides a method for cell handover, the method comprising:

[0038] receiving a measurement report of the user terminal equipment, making a handover decision and determining a handover target cell according to the measurement report;

[0039] Sending a handover preparation request to the base station of the target cell to which the target cell belongs, so that the target cell makes handover preparation;

[0040] receiving a handover preparation completion response from the base station of the target cell, and increasing the downlink transmit power of the target cell;

[0041] Sending a handover command to the user terminal equipment with the target cell as a handover object, and reducing the downlink transmission power of the source cell, so that the user terminal equipment randomly accesses the ta...

Abstract

The invention relates to a method for cell switching. The method comprises the following steps of receiving a measurement report of user terminal equipment, and making a switching decision and determining a switched target cell according to the measurement report; sending a switching preparation request to a target cell base station to which the target cell belongs in order to enable the target cell to make the switching preparation; receiving a switching preparation completion response from the target cell base station and increasing downlink transmitting power of the target cell; and sending a switching command to the user terminal equipment with the target cell as a switching object and reducing the downlink transmitting power of a source cell in order to make the user terminal equipment access to the target cell randomly. Through adoption of the method for cell switching of the invention, when the terminal switches between the cells, the downlink transmitting power of the source cell is reduced and an overlapping coverage area between the cells is narrowed through increasing the downlink transmitting power of the target cell, so that the interference time is reduced, and the quick recovery of the overall rate is guaranteed when the terminal switches between the cells.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a cell switching method and a base station. Background technique [0002] According to the definition of high-speed rail design specifications, trains with a speed of more than 250km / h are called high-speed rail. The TD-LTE (Time Division Long Term Evolution) high-speed rail private network does not use the public network and frequency bands of similar mobile / Unicom operators, and is also an independent site deployment network. The high-speed rail private network uses 1785 ~ 1805MHz. Because it belongs to the public frequency band, due to the limitation of spectrum resources, different frequency networking cannot be used, and the same frequency networking method is used. For the CPE terminal used in the high-speed rail private network, there is only one CPE terminal on a high-speed train set, and each carriage has a WIFI access point AP (Access Point), and all mobile phon...
