Cell reselection method and system, base station transceiver and base station controller

Abstract

The embodiment of the invention provides a cell reselection method and system, a base station transceiver and a base station controller. The method comprises the following steps: receiving at least two messages of a value indicating specific physical quantity from the base station controller, wherein the specific physical quantity indicates an idle user terminal in a cell to select the target cell; and changing the value of the specific physical quantity according to the value of the specific physical quantity indicated by each message of the at least two messages so that the value of the specific physical quantity respectively reaches the value of the specific physical quantity indicated by each message in different times, and the idle user terminals in the cell selects an adjacent cell in batches according to the value of the specific physical quantity. Base on the above technical scheme, the cell reselection of numerous user terminals can be effectively avoided, the occurrence of signaling storms and signaling congestions can be effectively prevented, the network performance reduction caused by signaling storms is avoided, and the network performance can be further improved.

Description

technical field [0001] The present invention relates to the field of communication, and more particularly, to a method for cell reselection in the field of communication, a base station transceiver, a base station controller and a system thereof. Background technique [0002] In order to build a network with large capacity, good coverage and excellent performance, mobile communication operators need to deploy tens of thousands of base stations. However, due to the high power consumption of traditional base stations, mainstream mobile operators in all countries around the world have become the country's power consumption. Can be big. This not only increases the operating costs of operators, but also makes them bear the huge social pressure of energy saving, emission reduction and environmental protection. Therefore, energy conservation and emission reduction has become one of the key tasks of major operators, and the importance of energy-saving technologies for base stations...

Problems solved by technology

[0006] Although closing the cell can save energy, the user terminal in the idle state will reselect the cell due to the sudden decrease in the signal strength of the BCCH carrier frequency because the user terminal in the idle state camps on the BCCH carrier frequency The base station of the target cell sends signaling requesting access, which will cause a signaling storm for the reselected target cell, causing signaling congestion and affecting network performance
