Problems solved by technology

But usually when the load of a cell is too high, there are more idle state (IDLE) UEs residing in the cell, and the UE in the connected state can only be handed over to other cells through the handover method, and the UE in the idle state is There is no good solution, so it is still impossible to solve the situation where there are many UEs residing in high-load cells

Embodiment Construction

[0099] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0100] Since the UE in the idle state cannot change cells through handover, and considering that cell reselection can be performed when the UE in the idle state initiates a connection, and cell reselection is performed according to the frequency priority information stored in the UE, this The embodiment of the invention considers adjusting the fre...

Abstract

The invention provides a method and a device for frequency priority adjustment. The method comprises steps that network access selection parameters of a first cell are determined by a base station; the network access selection parameters are sent by the base station to the UE in the first cell, and the network access selection parameters are used for making the UE in the first cell adjust the stored frequency priority configuration information. According to the method and the device for frequency priority adjustment, through adjusting the priority configuration of the UE, the UE is enabled to carry out cell reselection according to priority after adjustment, and thereby loads of cells can be reduced.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of wireless communication, and in particular, to a frequency priority adjustment method and device. Background technique [0002] In a Long Term Evolution (Long Term Evolution, LTE) system, one base station can provide multiple serving cells, and different cells are distinguished by different frequency points. A user equipment (User Equipment, UE) accessed by a base station may perform reselection or handover between different cells. [0003] In the LTE system, the cell reselection mechanism is cell reselection based on frequency priority. For the UE, each frequency point has a priority. After the UE is turned on, it will randomly camp on cells of different frequency points according to the search frequency. When the UE camps on a cell, it will continuously measure whether the cell with a high priority frequency point meets the camping criterion. If it meets the criteria, the UE w...
