Embodiment Construction

[0034] Considering the inconsistency of the system measurement periods of different networks in the cell reselection evaluation process in the related art, resulting in unnecessary reselection of different systems, the present invention proposes that the cell where the terminal currently resides in the current residency network In the case that all neighboring cells cannot be used as reselected cells, inter-system measurement can be started, thereby avoiding unnecessary reselection to cells of other networks when there are suitable cells in the current resident network, and reducing the processing burden of the terminal .

[0035] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

Abstract

The invention discloses a method and a terminal for implementing cell reselection. The method is used for implementing the cell reselection for the terminal which can support a first network and a second network and currently resides in a cell under the first network. The method comprises that: under the condition that cell reselection and evaluation are performed on the terminal, the terminal judges whether the signal strengths of the current resident cell and a neighboring cell of the resident cell under the first network meet the predetermined requirements in a predetermined cycle; and the terminal determines whether to start system measurement for the cell under the second network and whether to reselect the cell under the second network according to the judgment result. The method can reasonably control the start of different system measurement on the premise of keeping services normal, and avoid the unnecessary different system measurement so as to reduce the times of reselection between the systems, reduce the adverse effect of cross-system cell reselection on terminal services, effectively reduce call loss, improve the success rate of the services, lighten the processing burden of the terminal and reduce the power consumption of the terminal.

Description

technical field [0001] The present invention relates to the communication field, in particular to a cell reselection implementation method and a terminal. Background technique [0002] At present, dual-mode terminals (or multi-mode terminals) have been widely used in the market. These terminals can support two or more network types, can reside in cells under any type of network they support, and Use this network for communication. [0003] When a terminal resides in a cell under one of the supported networks, the terminal will detect the signal strength of the network to which the cell currently resides, and also detect the signal strength of other networks supported by the terminal, that is, it needs to Each network performs system measurement, and judges whether to perform reselection according to the system measurement result. [0004] Usually, when a terminal performs cell reselection, the system measurement periods of multiple networks supported by the terminal are di...
