Description

一种激活集的维护方法、终端及计算机存储介质 技术领域
本发明涉及移动通讯技术，尤其涉及一种激活集的维护方法、终端及计算机存储介质。
背景技术
当用户设备(UE，User Equipment)需要进行语音业务或大数据业务时，UE处于CELL-DCH状态，在该状态下，UE可能与多个小区间维持着无线链路(RL，Radio Link)，此时与UE维持RL的一组小区称为“激活集小区(Active Set Cell)”。激活集小区为一组工作频率相同的同频小区，个数最多达8个。激活集小区为UE进入连接态时，通过资源配置消息进行配置的。
另外，在UE中还维护一个邻小区列表，可以称为CELL_INFO_LIST，该列表中包括同频、异频、及异制式的邻区列表信息。每种邻区列表均为一个32位的数组，网络侧通过向UE下发系统信息或测量控制信息来更新邻小区列表。
在同频邻区列表中，除了激活集小区以外，还包括其他称为监测集(monitored set)的小区。而激活集小区并不是固定不变的，可以根据终端测量小区的信号强弱而动态的改变，即同频邻区中激活集小区与监测集小区可以互相改变。触发该改变是由一系列测量评估事件决定。根据终端协议，UE在进行测量评估事件时，进行测量评估所使用的激活集小区为资源配置消息进行配置的激活集小区与CELL_INFO_LIST中同频小区的交集。
可以理解的，由于CELL_INFO_LIST中邻小区信息来源于网络侧的系统信息数据或测控信息数据，那么当CELL_INFO_LIST中同频小区与资源 配置信息进行配置的激活集小区之间不统一时，会出现进行测量评估所使用的激活集小区为空集的情况。此时，由于无法进行测量评估事件，会造成数据业务中断；而且由于激活集信号质量反映UE界面的信号格显示，因此没有测量使用的激活集信息会造成UE界面的信号格无法显示的问题。

为了详细的说明本发明实施例的技术方案，本实施例以宽带码分多址(WCDMA，Wideband Code Division Multiple Access)系统为例进行说明，在终端进入CELL_DCH状态时，激活集小区列表可以通过终端自身的资源配置消息进行获取；可以理解的是，激活集小区列表中的小区包括与终端维持RL的一组小区，这些小区是工作频率相同的同频小区，个数最多可以达到8个。
S102：终端根据从网络侧接收的同频邻小区列表与激活集小区列表进行取交集运算；
需要说明的是，终端在进入CELL_DCH状态之后，可以通过接收网络侧发送的系统信息或测量控制信息获取邻小区列表，保存于CELL_INFO_LIST中，而在CELL_INFO_LIST中包括与终端同频、异频及异制式的邻小区信息，所以终端可以从CELL_INFO_LIST中得到同频邻小区列表。
可以理解的是，同频邻小区列表可以包括激活集小区列表中的小区，还可以包括除激活集小区以外的与终端同频的监测集小区；而同频邻小区列表中激活集小区与监测集小区可以互相改变，而改变的依据就是UE对同频邻小区列表与激活集小区列表的交集进行测量评估。因此，终端需要根据将同频邻小区列表与激活集小区列表进行取交集运算。
可以理解的是，取交集运算可以得到以下三种结果：激活集小区列表中的小区全部在同频邻小区列表中、激活集小区列表中的部分小区在同频邻小区列表中以及激活集小区列表中的小区全部不在同频邻小区列表中；
当取交集运算得到前两种结果的时候，终端可以按照目前现有的协议 流程进行测量评估，本实施例在此不作具体赘述；需要说明的是，当取交集运算得到最后一种结果的时候，由于激活集小区列表中的小区全部不在同频邻小区列表中，因此取交集运算最后得到的是空集，导致终端没有测量评估的目标，所以无法进行测量评估。
但是为了避免上述情况的出现，需要执行以下步骤：
S103：当同频邻小区列表与激活集小区列表的交集为空集时，终端将激活集小区列表中的激活集小区添加至同频邻小区列表的空位，得到添加后的同频邻小区列表，使得添加后的同频邻小区列表与激活集小区列表的交集为激活集小区列表中的全部小区，从而让终端获得测量评估的目标。避免发生无法进行测量评估事件的情形，减少终端业务中断的出现概率。
示例性地，步骤S103具体可以包括：
终端将激活集小区列表中激活集小区的标识添加至同频邻小区列表的空位，以及设置激活集小区在同频邻小区列表中对应的索引；
以及，为同频邻小区列表中的激活集小区设置添加标识，其中，添加标识用于指示同频邻小区列表中对应的小区为添加小区。
具体地，激活集小区列表中激活集小区的标识是与激活集小区对应的唯一标识，在本实施例中，可以优选为激活集小区的扰码；激活集小区在同频邻小区列表中对应的索引标识激活集小区在同频邻小区列表中的位置，例如同频邻小区列表中的小区标号CELLID，以便于根据索引检索到对应的激活集小区；激活集小区对应的添加标识用于指示该激活集小区是由终端主动从激活集小区列表中添加至同频邻小区列表中的，并不是终端根据从网络侧接收到的系统信息或测量控制信息中获取得到的。
通过上述过程得到的添加后的同频邻小区列表，不仅与激活集小区列表具有非空的交集，能够是终端进行后续的测量评估；而且还便于终端对两种小区进行区分。
另外，当终端通过步骤S101至S103得到添加后的同频邻小区列表后，还可以根据网络侧发送的新测量控制消息对添加后的同频邻小区进行更新，而新测量控制消息中可能会包括激活集小区列表中的部分或全部激活集小区，因此，参见图2，本实施例提供的激活集维护方法还可以包括S201至S205：
S201：终端在对添加后的同频邻小区列表进行更新之前，通过检索添加后的同频邻小区列表，获取添加后的同频邻小区列表中设置有添加标识的第一待删除同频邻小区对应的索引；
S202：终端根据第一待删除同频邻小区对应的索引将第一待删除同频邻小区从添加后的同频邻小区列表中删除，得到删除后的同频邻小区列表；
S203：终端根据网络侧发送的测量控制消息对删除后的同频邻小区列表进行更新，得到更新后的同频邻小区列表；
S204：终端根据更新后的同频邻小区列表与激活集小区列表进行取交集运算；
S205：当更新后的同频邻小区列表与激活集小区列表的交集为空集时，终端将激活集小区列表中的激活集小区添加至更新后的同频邻小区列表的空位。
需要说明的是，通过S203得到的更新后的同频邻小区列表中，可能会包括激活集小区列表中的部分或全部激活集小区，又或者测量控制消息中包括的新同频邻小区在终端的同频邻小区列表中的位置已经被S103添加的激活集小区所占据，因此，在步骤S203之前，终端需要通过步骤S201和S202在同频邻小区列表中删除通过S103添加的激活集小区，然后再对删除后的同频邻小区列表进行更新，接着将更新后的同频邻小区列表与激活集小区列表进行取交集运算，来确定是否需要在更新后的同频邻小区列表中添加激活集小区列表中的激活集小区。可以理解的是，步骤S204与S205 的具体过程与步骤S102和S103相同，本实施例在此不再赘述。
还需要说明的是，图1和图2所示的过程均为终端处于CELL_DCH状态的时候进行，而当终端离开CELL_DCH状态后，终端将无激活集小区这一概念，终端仅需要选择一个小区作为服务小区驻留，此时通过S103或S205所得到的同频邻小区列表中由终端添加的激活集小区并不是网络侧通过测量控制消息所指示的同频邻小区，因此，本实施例提供的激活集维护方法还可以包括：
终端在离开CELL_DCH状态后，检索同频邻小区列表中设置有添加标识的第二待删除同频邻小区对应的索引；
以及，终端根据第二待删除同频邻小区对应的索引将第二待删除同频邻小区从同频邻小区列表中删除，得到终端离开CELL_DCH状态后的同频邻小区列表。
可以理解的是，由于终端通过S103或S205将激活集小区列表中的激活集小区添加至同频邻小区列表的过程中，为添加的激活集小区对应设置了添加标识，因此，当终端需要从同频邻小区列表中删除添加的激活集小区的时候，可以检索同频邻小区列表中具有添加标识的小区，检索得到的则是添加至同频邻小区列表的激活集小区。
本实施例提供的一种激活集的维护方法，当CELL_INFO_LIST中同频小区与激活集小区之间的交集为空时，终端将激活集小区添加至CELL_INFO_LIST中同频小区的列表空位，能够防止在CELL_INFO_LIST中同频小区与资源配置信息进行配置的激活集小区之间不统一时出现无法进行测量评估事件的情形，而且还能够减少UE业务中断的出现概率。

添加单元304，配置为将激活集小区列表中的激活集小区添加至同频邻小区列表的空位，得到添加后的同频邻小区列表。
示例性地，添加单元304，具体可以配置为：

进一步地，参见图4，终端30还包括：第一检索单元305、第一删除单元306、更新单元307，其中，

进一步地，参见图4，终端30还包括：第二检索单元308和第二删除单元309，其中，
