Description

小区重选方法、闭合用户组验证的方法、装置及存储介质
相关申请的交叉引用
本申请基于申请号为201710682022.4、申请日为2017年08月10日的中国专利申请提出，并要求该中国专利申请的优先权，该中国专利申请的全部内容在此引入本申请作为参考。
技术领域
本发明涉及通信领域，尤其涉及一种小区重选方法、闭合用户组验证的方法、装置及存储介质。
背景技术
在相关技术中，闭合用户组(Closed Subscriber Group，CSG)是指允许接入一个或多个特定小区的一组签约用户。具有CSG属性的终端(User Equipment，UE)维护一张所属的CSG标识(identity，id)列表，其中每个CSG小区有一个CSG id，并且在广播消息里广播本小区的CSG id。UE参照广播的服务小区的CSG id和所维护的CSG id列表，判断服务小区是否允许接入。
在接入CSG小区的过程中，由于CSG的验证是双向的，即核心网也要验证UE的CSG属性。CSG小区的接入模式(Access Mode)包括：开放模式(Open Mode)、闭合模式(Close Mode)、混合模式(Hybrid Mode)。其中，所有UE都可以接入开放模式下的CSG小区；只有属于该CSG的成员的UE才可以接入闭合模式的CSG小区；所有UE都可以接入混合模式下的CSG小区，只是属于该CSG的成员的UE比普通UE的优先级高。移动性管理实体(Mobility Management Entity，MME)基于小区上报的CSG id 及Access Mode信息并根据UE的签约信息，判断该UE是否为此CSG小区的成员，完成UE的CSG验证。
由于UE所维护的允许接入的CSG id列表的信息和网络侧存储的签约信息可能不一致，如更新不及时带来的不一致，这是CSG需要双向验证的主要原因。对于不属于该CSG小区成员的UE，虽然可以驻留在该CSG小区以获得有限的服务(如地震、海啸等通知)；但是对该UE来说，如果需要选择理想的小区并接入的话，对于该CSG小区的质量测量及随机接入过程的功耗就全部浪费了。

S110、UE从网络侧获取邻小区的CSG信息；
S120、所述UE根据所获取的所述邻小区的CSG信息，确定允许接入的小区。
其中，UE可以将所确定的允许接入的小区作为小区质量测量的目标小区，完成小区的重选以及后续的小区接入。
一种实施方案中，所述CSG信息可以包括基站广播的邻小区的CSG属性信息；
所述S120可以包括：
UE根据所获取的邻小区的CSG属性信息，以及所述UE所维护的CSG列表(list)信息确定允许接入的小区。
其中，UE所维护的CSG列表可以包括允许接入的小区的CSG id。
本实施方式中，可以是当一个邻小区的CSG属性信息中的CSG id能够在UE维护的CSG list中匹配上时(或者说存在于UE维护的CSG list中时)，UE认为该邻小区是允许接入的的小区。
其中，所述邻小区的CSG属性信息可以包括以下一种或多种：

其中，相邻基站之间可以交互各自小区的CSG属性信息，比如一个基站有3个小区，则会将这3个小区的CSG属性信息发送给相邻的其它基站，并获取相邻的基站发送的小区CSG属性信息。基站可以周期性或在满足预定条件时向相邻基站发送本基站各小区的CSG属性信息，或向相邻的基站请求该基站各小区的CSG属性信息。
其中，一个基站可以广播所具有的各小区的CSG属性信息，比如包括本基站的3个小区、以及相邻基站小区的CSG属性信息。对于UE而言，会从基站广播的系统消息中获取到多个小区的CSG属性信息，除了目前接入的服务小区(后文也称为本小区)的CSG属性信息以外，还包括邻小区的CSG属性信息；而进行重选时，UE可以忽略服务小区的CSG属性信息，只根据邻小区的CSG信息，在邻小区中确定允许接入的小区。
一种实施方案中，可以在现有的系统信息块4(System Information Block  Type4，SIB4)消息里添加同频邻区的各个小区的CSG indication、CSG id信息，在SIB5消息里添加异频邻区的CSG-PhysCellIdrange，异频邻区的各个小区对应的CSG indication、CSG id等信息，包括：。

当需要进行小区重选时，UE根据基站广播的邻小区的CSG属性信息，以及所述UE所维护的CSG list信息确定允许接入的小区，如果基站广播的系统消息中一个邻小区的CSG id能够在UE维护的CSG list中匹配上，那么认为该邻小区是允许接入的，UE可针对该邻小区执行小区重选相关的测量。
其中，如果驻留在CSG小区的UE处于普通覆盖下(normal coverage)， 那么可以不启动异频邻区的测量，可以只进行同频邻区的测量；即，UE只在同频邻区中确定允许接入的小区。

其中，UE如果不是一个CSG小区的成员，则可以不测量该小区的质量。
其中，CSG验证过程可以包括：

本实施方案中，所述S110前还可以包括：
UE接入后向基站上报本地保存的对应于CSG验证结果信息的计数值；
所述S110还可以包括：
UE从基站接收计数值并保存为所述对应于CSG验证结果信息的计数值。
本实施方案中，基站可以将计数值上报给MME，并从MME接收CSG验证结果信息及对应的计数值，将所述计数值发送给所述UE，并根据MME的指示确定是否将CSG验证结果信息发送给所述UE。
本实施方案中，MME可以当UE上报的计数值和本地维护的该UE的计数值不一致时，完成该UE在本小区和邻小区的CSG验证，并更新本地的计数值，将该UE的CSG验证结果信息及更新后的计数值发送给基站，并指示基站发送给所述UE；当UE上报的计数值和本地维护的该UE的计数值一致时，完成该UE在本小区和邻小区的CSG验证，将该UE的CSG验证结果信息及计数值发送给基站，并指示基站不用发送CSG验证结果信息给所述UE。

一种CSG验证的方法的可选处理流程，如图3所示，包括步骤S310～S320：

下面用7个实施示例说明上述实施例。以下7个实施示例中，基站以eNB为例。
实施示例1，本实施示例中含邻小区CSG的验证过程，在基站触发的RRC连接释放过程中，CSG验证结果信息的传递及存储。
本实施示例如图4所示，包括如下步骤：
101、UE和基站之间进行RRC连接(RRC Connection)。
102、在RRC连接完成后，基站利用S1口的信令(如：本实施例中采用初始化UE消息(initial UE message))携带本小区的CSG验证信息，以及邻小区的CSG验证信息；其中，邻小区的CSG验证信息可以包括：邻小区的小区id及对应的CSG id、Access Mode。
103、MME在收到该S1口信令后，将进行该UE在本小区及邻小区的CSG验证过程。其中，MME与基站之间的接口为S1口。
104、MME验证完成后，将CSG验证结果信息通过S1口信令(如：本实施例中采用初始化上下文建立请求(initial context setup request))传给基站。
105、基站发送初始化上下文建立响应(initial context setup response)给MME。
106、在后续的过程中，基站触发的RRC连接释放(RRC Connection  Release)消息中，基站将该UE的CSG验证结果信息带给UE。
107、UE将CSG验证结果信息作为UE的上下文信息(UE Context)的内容进行存储。其中，CSG验证结果信息中，成员状态member status包括两种状态：成员member、非成员non-member。
本实施示例中，基站触发RRC连接释放，在RRC连接释放消息中将CSG验证结果信息带给UE，这样处于RRC空闲态UE，将会存储有CSG验证结果信息的UE Context。UE读取基站广播的系统消息中本小区和邻小区的信息，并根据存储的CSG验证结果信息中的PLMN id、小区id、CSG id、成员状态，确定广播的小区中成员状态值为“member”的小区，作为可接入的理想小区并作为小区质量测量的目标小区，确定广播的小区中成员状态值为“non-member”的小区，作为可获得有限服务(如地震、海啸等通知)的小区。
另外对于RRC连接释放消息支持非确认模式(Unacknowledged Mode，UM)模式的UE，在RRC连接建立的过程中，如RRC连接建立完成消息中将UE的这种UM支持能力带给基站，或者通过专用的能力信息带给基站，基站在发送RRC连接释放消息时，如果UE支持UM方式，那么基站在发送完该消息后立即释放UE的上下文，不需要等待UE发送对该条消息的确认消息后再释放UE的上下文信息。支持这种能力的UE，在收到基站发送RRC连接释放消息后，不需要发送该条消息接收状态的反馈确认信息。
实施示例2，本实施示例中含邻小区CSG的验证过程，在NAS消息触发的RRC连接释放过程中，CSG验证信息的传递及存储。
本实施示例如图5所示，包括如下步骤：
201、UE和基站之间进行RRC连接。
202、在RRC连接完成后，基站利用S1口信令(如：本实施例中采用 initial UE message)携带本小区的CSG验证信息，以及邻小区的CSG验证信息；其中，邻小区的CSG验证信息可以包括：邻小区的小区id及对应的CSG id、Access Mode。
203、MME在收到该S1口信令后，将进行该UE在本小区及邻小区的CSG验证过程。
204、MME验证完成后，将CSG验证结果信息通过S1口信令(如：本实施例中采用initial context setup request)传给基站。
205、基站发送initial context setup response给MME。
206、在后续的过程中，核心网触发的RRC连接释放过程中，MME将该UE的CSG验证结果信息放在NAS协议数据单元(Protocol Data Unit，PDU)中，通过下行链路非接入层传输(DL NAS Transport)消息发送到基站。
207、基站通过下行链路信息传输(DL NAS Transport)消息，将CSG验证结果信息的NAS PDU带给UE。
208、UE将CSG验证结果信息作为UE的上下文信息(UE Context)的内容进行存储。
本实施例中，通过NAS消息触发RRC连接释放，并在NAS消息中将CSG验证结果信息带给UE，这样处于RRC空闲态UE，将会存储有CSG验证结果信息的UE Context。UE读取基站广播的系统消息中本小区和邻小区的信息，并根据存储的CSG验证结果信息中PLMN id、小区id、CSG id、成员状态，确定广播的小区中成员状态值为“member”的小区，作为可接入的理想小区并作为小区质量测量的目标小区，确定广播的小区中成员状态值为“non-member”的小区，作为可获得有限服务(如地震、海啸等通知)的小区。
实施例3，本实施例中含对于RRC连接挂起的UE的CSG验证信息的 传递及存储。
本实施例中，在基站触发的RRC连接挂起的过程中，基站将该UE的CSG验证结果信息带给UE，如在RRC连接挂起(RRC Connection Suspend)消息中将该UE的CSG验证结果信息带给UE。UE收到该消息后，将CSG验证结果信息作为UE的上下文信息(Context)的内容进行存储。基站也会存储包含有UE的CSG验证结果信息的UE的Context。
本实施例如图6所示，包括以下过程：
301～305和101～105相同，这里不再赘述。
306、基站发送UE上下文挂起请求(UE Context Suspend Request)给MME。
307、MME进行UE的Context的存储。
308、MME发送UE上下文挂起响应(UE Context Suspend Response)给基站。
309、基站发送RRC Connection Suspend消息给UE。
310、UE将CSG验证结果信息作为UE Context的内容进行存储；基站将UE的Context(含有UE的CSG验证结果信息)进行存储。
实施例4，本实施例中包含对于存储有CSG验证结果信息的UE上下文信息的基站，在RRC空闲态UE发起RRC连接恢复的过程中、RRC连接态UE的切换过程中，CSG的验证方法。
图7是处于RRC空闲态、上下文挂起状态的UE在RRC连接恢复的过程中，UE的CSG验证方法，包括以下过程：
401、UE发送RRC连接恢复请求(RRC Connection Resume Request)消息给基站，其中携带UE的Context。
402、对于处于RRC空闲态、上下文挂起状态的UE，基站根据本基站存储的UE Context和该UE上报的UE Context进行匹配，并进行CSG的验 证。
403、如果允许接入，则基站发送RRC连接恢复(RRC Connection Resume)消息给UE。
404、UE发送RRC连接恢复完成(RRC Connection Resume Complete)消息给基站。
405、基站发送UE上下文恢复请求(UE Context Resume Request)给MME。
406、MME匹配UE的Context。
407、MME发送UE上下文恢复请求(UE Context Resume Response)给基站。
从上面的过程可以看到，本实施例在RRC连接恢复的过程中，将在RRC连接恢复信令中携带用于RRC连接恢复相关的UE的Context。在RRC连接恢复信令中携带的UE的Context可以不包含CSG验证结果信息，基站在收到携带该UE的Context的RRC连接恢复请求消息后，将匹配UE的Context，而后基站将根据最新的Access Mode并结合存储的该UE的CSG验证结果信息进行此次RRC连接恢复过程中的CSG的验证。
如之前存储的CSG验证信息的Access Mode为混合模式Hybrid，CSG验证结果为非成员non-member，上次接入该小区是允许的；如果在此次恢复连接的过程中，小区的接入模式Access Mode为封闭的Close Mode，那么CSG的验证结果为非成员non-member，即此次RRC连接恢复过程将被禁止。如果小区的接入模式不是Close Mode，则允许接入该小区，进行上述步骤403～407。
本实施例中，对于RRC连接态的UE，在切换的过程中，源基站存储有包含CSG验证结果信息的UE上下文信息，源基站将根据该CSG验证结果信息，从验证结果为UE的CSG成员的小区中选择目标小区。
实施例5，本实施例中，通过在UE侧及MME侧设置CSG验证相关的计数器，优化CSG的验证及验证结果信息的传递。
本实施例中，UE第一次得到CSG验证结果信息的情况如图8所示，501～507和101～107基本相同，在如下步骤具有区别：
503中，MME不仅进行UE在本小区及邻小区的CSG验证过程，而且启动计数器，开始计数。
504中、MME验证完成后，将CSG验证结果信息以及计数器的计数值一起通过S1口信令传给基站。
506中，基站在触发的RRC Connection Release消息中，除了该UE的CSG验证结果信息，还将计数器的计数值带给UE。
507、UE将CSG验证结果信息作为UE Context的内容进行存储，并存储计数器的计数值。
本实施例中，在UE侧及MME侧设置CSG验证相关的计数器，其中，MME对每个UE单独为一个CSG验证相关的计数值。
本实施例中，MME在完成UE的CSG验证后，启动计数器并开始计数如“1”。MME和基站在传递CSG验证结果信息的同时传递MME中当前计数器的计数值。在RRC连接释放后处于空闲态的UE存储CSG验证结果信息，并启动计数器记录所收到的计数值“1”。
RRC空闲态的UE在接收基站广播的系统消息后，如果发现邻区列表信息与存储的CSG验证结果信息中的邻区列表发生变化，启动计数器将所保存的计数值增加“1”。
实施例6，本实施例包含在UE侧及MME侧设置CSG验证相关的计数器时，UE后续接入网络时的情况。
UE侧的计数器计数值发生变更的情况如图9a所示，在后续接入网络时，进行如下操作：
601、UE和基站之间进行RRC连接，UE在RRC连接建立的过程中，如RRC连接建立完成消息中将UE侧的计数值带给基站。
602、在RRC连接完成后，基站将该计数值及CSG验证信息通过S1口信令带给MME。
603、MME在收到S1口信令后，将进行该UE在本小区及邻小区的CSG验证过程，并比较收到的计数值及存储的计数值，如果发现不一致，则MME将在完成CSG相关的验证后，更新所存储的计数值，得到计数器更新值。
604、MME验证完成后，在通过initial context setup request将CSG验证结果信息带给基站的同时将计数器更新值也带给基站，并指示需要将CSG验证结果信息及计数器更新值传给UE。
605、基站发送initial context setup response给MME。
606、在RRC释放链接的过程中，基站通过RRC连接释放消息将CSG验证结果信息及计数器更新值带给UE。
607、UE更新所存储的CSG验证结果信息。
UE侧的计数器计数值未发生变更的情况如图9b所示，在后续接入网络时，进行如下操作：
701、UE和基站之间进行RRC连接，UE在RRC连接建立的过程中，如RRC连接建立完成消息中将计数值带给基站。
702、在RRC连接完成后，基站将该计数值及CSG验证信息通过S1口信令带给MME。
703、MME在收到S1口信令后，将进行该UE在本小区及邻小区的CSG验证过程，并比较收到的计数值及存储的计数值，发现一致。
704、MME在完成CSG相关的验证后，通过initial context setup request将CSG验证结果信息及网络侧的计数值带给基站，并指示不需要将CSG 验证结果信息传给UE。
705、基站发送initial context setup response给MME。
706、在RRC释放链接的过程中，基站通过RRC连接释放消息将网络侧的计数值带给UE。
707、基站发送的计数值与UE侧的计数值一致，UE将维持原有的CSG验证结果信息的存储。
实施示例7，本实施示例用来说明对于采用传统方法的系统或新的系统，如何引入CSG功能。
对于如M2M系统的窄带物联网(Narrow Band Internet of Things,NB-IoT)系统，如果引入CSG功能的话，对于该系统和LTE系统中共有的一些过程，可以使用LTE中那套CSG验证的方法；但是对于该系统特有的过程如RRC连接恢复过程，RRC resume过程，可以引入CSG的验证过程，比如可以在UE上下文恢复请求消息中携带CSG验证信息(包括小区标识，CSG标识)；在UE上下文恢复响应消息中将验证结果信息(包括CSG成员状态，CSG membership status)带给基站，而可以不是由基站进行CSG验证。
对于新的系统，引入CSG功能的处理过程可以类推。
