移动性管理能够辅助长期演进(Long Term Evolution，缩写：LTE)通信系统实现负载均衡、提供更好的用户体验以及提高系统整体性能。
为便于阐述，将当前为终端服务的小区，即终端当前驻留的小区称之为服务小区，终端选择或者重选的小区称之为目标小区。移动性管理功能主要分为两类：空闲状态的移动性管理和连接状态的移动性管理。其中空闲状态的移动性管理主要由终端基于网络配置的静态参数来自主决策，连接状态的移动性管理主要由网络侧基于终端的测量上报来决策。
在空闲状态的移动性管理中，终端需要参考小区配置的最小接收电平值(表示为Qrxlevmin)来决定当前小区是否是合适驻留的小区。其中，在小区选择阶段，如果终端当前的信号电平值高于某一小区的Qrxlevmin，则终端会将该小区作为目标小区来驻留。而在小区重选阶段，终端首先将测量到的满足驻留条件的相邻小区的信号强度值或以其为变量的函数值进行排序，然后根据排序结果，将信号电平值或信号电平值的等价参数值最大的小区作为目标小区，最后，终端在重选出的小区中驻留。该种方式中，在进行小区重选时，可能会因为目标小区的Qrxlevmin值比当前小区中为该小区所部署频率专有的Qrxlevmin高导致终端在两个或多个小区之间出现乒乓重选。
在连接状态的移动性管理中，在进行目标小区选择时，仅仅基于终端上报的当前服务小区的信号电平值、终端测量得到的邻小区的信号电平，和邻小区 的资源来决定目标小区。但是该种方式中，网络侧选择的目标切换小区并不能完全保证终端接入过去之后，能正常完成随机接入以及其它上行流程，因此小区选择有效性较差。
综上所述，当前移动性管理中进行小区重选时，终端可能会在两个或多个小区之间出现乒乓重选或可能导致终端驻留失败，或在当前服务小区切换判决中进行小区选择时，有效性较差。

具体实施方式
本公开实施例提出的技术方案中，每个小区引入频率专有最小接收电平frequency specific Qrxlevmin值和小区专有最小接收电平偏置Cell specific Qrxlevmin-offset值，在移动性管理中，进行小区选择时，综合考虑引入frequency specific Qrxlevmin值和Cell specific Qrxlevmin-offset值的和值，得到最终的目标小区，能够较好地解决当前移动性管理中进行小区重选时，终端可能会在两个或多个小区之间出现乒乓重选或可能导致终端驻留失败，或在进行小区选择时，有效性较差的问题。
下面将结合各个附图对本公开实施例技术方案的主要实现原理、具体实施方式进行详细地阐述。
在空闲状态的移动性管理中，终端需要参考小区配置的参数Qrxlevmin值来决定当前小区是否是终端合适的驻留小区。由于目前标准定义中，对于小区配置的参数Qrxlevmin值是频率专有的，因此若终端在进行小区选择时，若只参考频率专有的Qrxlevmin值时，可能会使得终端在至少两个以上的小区之间进行反复选择，若终端同时参考小区的信号电平值，则会使得小区选择的速度较慢。基于此，本公开一些实施例一提出一种在空闲状态的移动性管理方法， 如图1所示其具体处理流程如下述。
步骤10，服务小区获得各邻小区预先配置的Cell specific Qrxlevmin-offset值。

步骤11，服务小区广播各邻小区的Cell specific Qrxlevmin-offset值。
服务小区可以通过广播消息的方式，将邻小区的预先配置的frequency specific Qrxlevmin值告知终端。
步骤12，终端获得服务小区各邻小区的frequency specific Qrxlevmin值、各邻小区预先配置的Cell specific Qrxlevmin-offset值，以及各邻小区的信号电平值。
终端可以在服务小区中获得服务小区各邻小区的frequency specific Qrxlevmin值和为各邻小区预先配置的Cell specific Qrxlevmin-offset值。
其中，终端可以对系统广播消息中的频点进行测量，确定各邻小区的信号电平值。
步骤13，针对任一邻小区，计算该邻小区的frequency specific Qrxlevmin值与Cell specific Qrxlevmin-offset值的和值。
本公开一些实施例中，在终端侧，提出一种移动性管理方法，包括：
步骤一：获得服务小区各邻小区的frequency specific Qrxlevmin值、各邻小区预先配置的Cell specific Qrxlevmin-offset值，以及各邻小区的信号电平值。

Figure PCTCN2015100119-appb-000002

其中，终端可以对系统广播消息中的频点进行测量，确定各邻小区的信号电平值。
