Cell reselection method and mobile terminal

Abstract

The embodiment of the invention provides a cell reselection method and a mobile terminal. The cell reselection method includes the steps that in the cell reselection process, if it is determined that a current serving cell is a high-quality cell, a user selects to stay in the serving cell continuously, wherein the high-quality cell is a cell which meets judgment rules for being promoted to be a high-quality cell. According to the cell reselection method and the mobile terminal, cells which meet the judgment rules for being promoted to be high-quality cells are managed as high-quality cells; in the cell reselection process, if the situation that the current serving cell belongs to the high-quality cell occurs, through the processing mode that the user selects to stay in the current serving cell, frequent switching between the cells is reduced, the business service quality is improved, and the power consumption of the mobile terminal is reduced.

Description

technical field [0001] The embodiments of the present invention relate to wireless communication technologies, and in particular to a cell reselection method and a mobile terminal. Background technique [0002] In order to enable users to enjoy better services, it is necessary to ensure that a mobile terminal (User Equipment; UE for short) resides in a cell with better quality. The existing technology strictly follows the 3rd Generation Partnership Project (3rd Generation Partnership Project; abbreviation: 3GPP) standard protocol specification; when the UE resides in a cell of a certain standard, it monitors the surrounding adjacent area conditions in real time, and sends the information according to the network side The selection / reselection parameters of the system message are used to decide whether to perform cell selection / reselection and handover between different systems. When the UE measures and finds that the signal quality of the serving cell where it is currently ...

[0003] However, in the prior art, since the UE decides whether to perform cell handover according to the selection / reselection parameters of the system message issued by the network side, the following situation may occur: the signal quality of the current serving cell is good, but there is a pilot Pollution, according to the existing technology, the UE may drop from a Wide band Code Division Multiple Access (WCDMA) cell (W for short) to a Global System for Mobile Communications (GSM) cell (abbreviated as G); and due to some factors, the signal quality of the current serving cell is only bad in a short period of time, but according to the existing technology, when the network parameter configuration is unreasonable, the UE will still fail because of Such a short-term signal quality is not good and the UE switches to a neighbor cell, and then after the signal quality of the previous serving cell returns to a better state, the UE switches back again, resulting in a ping-pong effect between W and G, and a ping-pong effect between W or G. ping pong effect
