Abstract

本发明公开了一种移动通信终端小区锁定的方法，RR层收到L1报告的信号最强的6个小区后，对每一个小区进行判断，如果该小区不是应用层锁定的小区，那么把该小区的强度标记为0，直到找到一个应用层锁定的小区，才将该小区设置为可用小区，否则进入无网络状态。本发明可有效解决当应用层锁定的小区不是目前信号最强的小区而导致移动通信终端进入不可用的小区的问题，适用于移动通信领域。

Description

移动通信终端小区锁定的方法
技术领域
本发明涉及一种移动通信终端设备进行小区选择和小区锁定的方法。
背景技术
目前在移动通信终端设备中，小区选择和小区锁定是相互独立的两个部分。小区选择按照3GPP 05.08协议(无线子系统链路控制RadioSubsysterm Link Control)进行；小区锁定是应用层在得到RR(radioresource management无线资源管理)层报告上来的小区信息后，通过比较信号强弱的方法进行小区筛选的。按照目前这种方法，若运营商将终端锁定某个小区，而在这个小区的边沿有另外信号比较强的小区时，终端就可能处在将信号较强、但应用层认为不可用的小区选为可用小区的状态。造成的结果是在许多运营商认为应该能使用的地方终端却不可用。此外，当终端处于有效小区和无效小区的交叉区域时，经常会在两个小区之间进行切换。当切换到有效小区时终端可用，当切换到无效小区时终端不可用。如果两个小区的功率在不断变化的时候(实际上，由于许多外界因素的影响，在固定点上某个小区的功率是不断变化的)终端就有可能在可用和不可用之间频繁地来回切换，严重影响了用户的正常使用。
发明内容
本发明要解决的技术问题是提供一种移动通信终端小区锁定的方法，它可有效解决当应用层锁定的小区不是目前信号最强的小区而导致移动通信终端进入不可用的小区的问题。
为解决上述技术问题，本发明所采用的技术方案是：RR层收到L1(第一层即物理层)报告的信号最强的6个小区后，对每一个小区进行判断，如果该小区不是应用层锁定的小区，那么把该小区的强度标记为0，直到找到一个应用层锁定的小区，才将该小区设置为可用小区，否则进入无网络状态。
采用本发明的方法后，可使移动通信终端选定的可用小区是应用层所需要的小区，或者处于无网络状态。因此，当移动通信终端处于无效小区和有效小区交叉的区域时，即使无效小区的强度大于有效小区的某一时刻，RR层也会优先选择其中的有效小区，避免了移动通信终端频繁切换而影响用户的正常使用。
附图说明
下面结合附图和实施方式对本发明作进一步详细说明。
附图是本发明移动通信终端小区锁定方法的流程图。
具体实施方式
如图所示，本发明移动通信终端小区锁定的方法是，首先，由RR层选择小区；然后L1从中挑选出信号最强的六个小区，并报告给RR层；RR层收到L1报告的信号最强的6个小区后，对每个小区进行判断，确认是否为应用层锁定的小区；若该小区不是应用层锁定的小区，则将该小区的强度标记为0，若该小区是应用层锁定的小区，则将该小区设置为可用小区。

Claims (1)

1、一种移动通信终端小区锁定的方法，其特征在于：首先，由RR层选择小区；然后L1从中挑选出信号最强的六个小区并报告给RR层；RR层对该六个小区分别进行判断，确认是否为应用层锁定的小区；若该小区不是应用层锁定的小区，则将该小区的强度标记为0，若该小区是应用层锁定的小区，则将该小区设置为可用小区。
