Description

一种邻区添加方法、装置及基站 技术领域
本发明涉及无线通信领域，尤其涉及一种邻区添加方法、装置及基站。
背景技术
在LTE系统中，存在独立载波共享的网络共享场景，具体是指演进的通用陆基无线接入网节点eNB(E-UTRAN NodeB，Evolved Universal Terrestrial Radio Access Network NodeB)下服务小区在广播中下发的公共陆地移动网络标识信息(PLMN，Public Land Mobile Network)与eNB的Global eNB ID中的PLMN不相同的网络共享场景。在独立载波共享场景下做切换时，切换信令中目标小区的演进的通用陆基无线接入网小区全局标识信息(ECGI，E-UTRAN Cell Global Identifier，Evolved Universal Terrestrial Radio Access Network Cell Global Identifier)中的PLMN要与目标小区所在eNB的PLMN相同，这样切换信令才能够被正确的路由转发至目标eNB。而在独立载波共享场景下，执行自动邻区关系切换(ANR，Automatic Neighbor Relation)的过程中，通过ECGI测量获取的PLMN信息是邻区广播中下发的PLMN信息，这个PLMN信息与邻接eNB的PLMN信息不同，那么通过ANR添加的邻区上发生的切换将会由于切换信令不能正确发送到邻接eNB而发生切换失败。
例如：eNB A和eNB B邻接，并且都处于独立载波共享网络内，eNB A下有小区1和小区2，eNB B下有小区3和小区4。eNB A的PLMN信息为PLMN1，小区1的广播中下发的PLMN信息为PLMN1，小区2的广播中下发的PLMN信息为PLMN2，eNB B的PLMN信息为PLMN3，小区3的广播中下发的PLMN信息为PLMN3，小区4的广播中下发的PLMN信息为PLMN4。那么小区1在通过对小区3执行ECGI测量来添加邻区时，测量到的小区3的ECGI中的PLMN信息是PLMN3。如果UE在从小区1向小区3切换时，小区1直接使用包含了PLMN1和小区3标识的ECGI来填写切换信令时，切换信令将被正确的转发到eNB B，因为eNB B的PLMN为PLMN3，于是切换成功。而当小区1在通过对小区4执行ECGI测量来添加邻区时，测量到的小区4的ECGI中的PLMN信息是PLMN4。如果UE在从小区1向小区4切换时，小区1直接使用包含了PLMN1和小区4标识的ECGI来填写切换信令时，切换信令将不能被正确的转发到eNB B，因为eNB B的PLMN为PLMN3，于是切换将失败。
由于自动切换存在上述切换失败的问题，而人工配置邻区工作量很大。那么，在独立载波共享场景下，就需要一种方法能够正确添加邻区的方法，以保证UE切换时使用正确的邻区PLMN信息。
发明内容

具体实施方式

为解决上述提及的，在独立载波共享的网络共享场景下做切换时，由于服务小区获取到的目标小区的PLMN信息与目标小区实际PLMN信息不一致，而造成的切换失败问题，如图1所示，本发明的实施例提供了一种邻区添加方法，具体包括以下步骤：
步骤10：获取服务小区的相邻小区的ECGI信息。
这里，ECGI信息由PLMN信息+Cell Identity信息组成，用于在PLMN中全局标识一个小区，其中，ECGI信息中还携带有相邻小区的测量PLMN，其中测量PLMN信息指的是相邻小区广播中携带的PLMN信息。
步骤20：根据预先设置的测量PLMN信息与目标PLMN信息之间的映射关系，检测是否能够匹配得到与相邻小区的ECGI信息对应的目标PLMN信息，得到检测结果。
这里，由于小区广播的PLMN信息不一定是小区所属基站的实际PLMN信息，为了保证用户终端UE能够成功切换至相邻小区，在基站侧预先设置有各个小区的测量PLMN信息与目标PLMN信息之间的映射关系，其中，目标PLMN信息指的是小区所属基站的实际PLMN信息。
步骤30：若检测结果为：匹配到与相邻小区的ECGI信息对应的目标PLMN信息，则将匹配得到的目标PLMN信息作为相邻小区的实际PLMN信息配置在服务小区的邻区配置中。
这里是指，若检测到上述相邻小区的测量PLMN信息能够匹配到与相邻小区的ECGI信息对应的目标PLMN信息，也就是说当前的相邻小区的测量PLMN与所属基站的实际PLMN信息不一致，这时会采用目标PLMN信息作为相邻小区的实际PLMN信息，并将其配置在当前服务小区的邻区配置中。
除了上述小区广播的PLMN信息与实际PLMN信息不一致的情况，还包括如图2所示的情况：
步骤40：若检测结果为：未匹配到与相邻小区的ECGI信息对应的目标PLMN信息，则将相邻小区的测量PLMN信息配置在服务小区的邻区配置中。
这里，当检测到上述相邻小区的测量PLMN信息未能匹配到与相邻小区的ECGI信息对应的目标PLMN信息时，也就是说小区广播的PLMN信息与实际PLMN信息一致的情况，这时与现有ANR方式类似，可直接将测量PLMN信息配置在当前服务小区的邻区配置中。
以上述背景技术中提及的应用场景为例，假定当前的服务小区为小区1，所属基站为eNB A，相邻小区为小区2、小区3和小区4，其中，小区1和小区2同属基站eNB A，而小区3和小区4同属基站eNB B；其中，eNB A的PLMN信息为PLMN1，小区1的广播中下发的PLMN信息为PLMN1，小区2的广播中下发的PLMN信息为PLMN2，eNB B的PLMN信息为PLMN3，小区3的广播中下发的PLMN信息为PLMN3，小区4的广播中下发的PLMN信息为PLMN4。当小区1通过对小区3执行ECGI测量来添加邻区时，测量到的小区3的ECGI信息中的PLMN信息为PLMN3，而小区3所属基站eNB B的PLMN信息也为PLMN3，这时可直接将测量PLMN信息配置在当前服务小区的邻区配置中。
具体地，步骤10的实现可参照以下步骤，如图3所示：
步骤11：向用户终端发送相邻小区的ECGI测量配置信息，以使用户终端接收到相邻小区广播的ECGI信息。
这里，当多个小区共基站时，在基站侧存储有各个小区的ECGI测量配置信息，当UE需要切换小区时，基站会向UE发送相邻小区的ECGI测量配置信息，当UE得到相邻小区的ECGI测量配置信息后，才能够接收该相邻小区的广播信息，从而得到相邻小区的ECGI信息。
步骤12：接收用户终端上报的相邻小区的ECGI信息。
这里，UE获得相邻小区的ECGI信息后，会将该ECGI信息反馈至基站侧，以使基站能够进行后续的邻区切换工作。
当服务小区的基站获得相邻小区的ECGI消息后，进行步骤20，而步骤20中提及的预先设置的测量PLMN信息与目标PLMN信息之间的映射关系，具体可存储在基站侧的配置表中，即在基站侧设置一PLMN映射表，在PLMN映射表中记录有预定范围内各个小区的测量PLMN信息与对应基站的目标PLMN信息之间的映射关系。考虑为独立载波共享网络范围的eNB都统一配置一份PLMN映射表，该表中记录有测量PLMN信息与目标PLMN信息的映射关系。测量PLMN信息为小区ECGI测量得到的UE上报的ECGI中包含的PLMN信息，目标PLMN信息为独立载波共享区域中基站的PLMN信息，因此测量PLMN信息与目标PLMN信息是多对一关系，以上述应用场景为例，预先配置在服务小区所属基站内的PLMN映射表如下所示：
测量PLMN 目标PLMN
2 1
4 3
上表表示，小区2的测量PLMN信息为PLMN2，而所属基站eNB A的实际PLMN信息为PLMN1，小区4的测量PLMN信息为PLMN4，而所属基站eNB B的实际PLMN信息为 PLMN3。
这样步骤20的具体实现可参照以下方式：检测相邻小区的测量PLMN信息是否配置在预先创建的PLMN映射表中的测量PLMN范围内，以得到检测结果。
再根据检测结果做出不同的配置策略，具体可参照如步骤30或步骤40所述的配置策略。得出配置策略之后，还需要按照配置策略进行UE的邻区切换。具体地，在步骤30之后，还包括：根据相邻小区的实际PLMN信息，将用户终端切换至相邻小区。或者，
在步骤40之后，还包括：根据相邻小区的测量PLMN信息，将用户终端切换至相邻小区。
以下，将结合上述应用场景，对该邻区添加方法进行详细说明，如图4所示，当UE需要由小区1切换至小区4时，需执行以下操作：
小区1所属基站eNB A向UE发送小区4的ECGI测量配置信息；
UE根据上述ECGI测量配置信息，接收小区4广播的ECGI信息；
eNB A接收UE上报的小区4的ECGI信息，其中，该ECGI信息中包含有小区4的测量PLMN信息PLMN4；
eNB A检测到PLMN4包含在PLMN映射表中，使用PLMN4对应的目标PLMN3来替换PLMN4，使用替换后包含PLMN3的ECGI添加邻区4的邻区配置；以此来对UE进行邻区切换；
这样即可保证UE的切换成功。
值得指出的是，以上所提及的服务小区或者相邻小区可以是LTE小区、UTRAN小区或GERAN小区，也就是说以上所述的邻区添加方法可适用于4G、3G或2G小区所属的基站。以下，将分为三个实施例对此进行说明：
