一种小区选择方法及相关设备
相关申请的交叉引用
本公开要求在2019年09月27日提交中国专利局、申请号为201910924401.9、申请名称为“一种小区选择方法及相关设备”的中国专利申请的优先权，其全部内容通过引用结合在本公开中。
技术领域
本公开涉及通信技术领域，尤其涉及一种小区选择方法及相关设备。
背景技术
非公网络(non-public network，NPN)，与公共网络(public network)不同，NPN指针对用户存在一些限制的私有网络，每一个非公网络均对应有网络标识。NPN允许有授权信息的终端设备接入。一个小区可以支持多种NPN，小区可以在系统信息中指示自身能够支持的网络。
终端设备中配置有自身注册或签约的网络对应的授权信息，由于终端设备无法得知各小区能够支持的NPN，因此终端设备需要读取各个小区的系统信息，获取对应小区能够支持的网络。如果终端设备当前获取的小区能够支持的网络不包括终端设备注册或签约的网络，那么终端设备需要继续读取其它小区的系统信息，这样一来，终端设备需要对多个小区分别进行测量，终端设备的耗电量较大。

具体实施方式
为了本领域技术人员更好地理解本公开，下面集合附图对本公开进行介绍。
下面对本公开涉及的一些专业术语进行介绍。
(1)网络设备：是通信系统中将终端接设备入到无线网络的设备。所述网络设备为无线接入网中的节点，又可以称为基站，还可以称为无线接入网(radio access network，RAN)节点(或设备)。目前，一些网络设备的举例为：gNB、传输接收点(transmission reception point，TRP)、演进型节点B(evolved Node B，eNB)、无线网络控制器(radio network controller，RNC)、节点B(Node B，NB)、基站控制器(base station controller，BSC)、基站收发台(base transceiver station，BTS)、家庭基站(例如home evolved NodeB，或home Node B，HNB)、基带单元(base band unit，BBU)，或无线保真(wireless fidelity，Wifi)接入点(access point，AP)等。另外，在一种网络结构中，网络设备可以包括集中单元(centralized unit，CU)节点和分布单元(distributed unit，DU)节点。这种结构将长期演进(long term evolution，LTE)系统中eNB或者新空口(New Radio，NR)系统中下一代基站(generation Node B，gNB)的协议层拆分开，部分协议层的功能放在控制单元(CU)集中控制，剩下部分或全部协议层的功能分布在数据单元(Data Unit，DU)中，由CU集中控制DU。本公开实施例中的网络设备在没有特别说明的情况下，一般是指服务小区所对应的网络设备。
(2)终端设备：又称之为终端、用户设备(user equipment，UE)、移动台(mobile station，MS)、移动终端(mobile terminal，MT)等，是一种向用户提供语音和/或数据连通性的设备，例如，具有无线连接功能的手持式设备、车载设备等。目前，一些终端的举例为：手机(mobile phone)、平板电脑、笔记本电脑、掌上电脑、移动互联网设备(mobile internet device，MID)、可穿戴设备，虚拟现实(virtual reality，VR)设备、增强现实(augmented reality，AR)设备、工业控制(industrial control)中的无线终端、无人驾驶(self-driving)中的无线终端、远程手术(remote medical surgery)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等。
(3)服务小区(Serving cell)：是为终端设备提供服务(例如上下行传输)的小区。如果终端设备处于无线资源控制(Radio Resource Control，RRC)连接(RRC_CONNECTED)态但并未配置载波聚合(Carrier Aggregation，CA)，则该终端设备只有一个服务小区，即(primary Cell，PCell)；如果终端设备处于RRC_CONNECTED态且配置CA，则该终端设备的serving cell包括PCell和所有的辅小区(secondary cell，SCell)。也就是说，serving cell既可以指代PCell，也可以指代SCell。PCell和SCell均可以为服务小区。
(4)私有小区：本公开实施例中是指仅支持NPN的小区，也就是说，私有小区无法支持公共网络。
(5)非公网络(non-public network，NPN)：区别于公共网络(public network)，指针对用户存在一些限制的私有网络。每一个非公网络有对应的网络标识。目前NPN的网络类型包括以下两种：
①独立组网非公有网络(Stand-alone non-public networks，SNPN)：可以使用公共陆地移动网络(Public Land Mobile Network Identity，PLMN ID)，以及网络识别码(Network Identification，NID)进行标识。其中，PLMN ID由移动国家码(Mobile Country Code， MCC)与移动网络码(Mobile Network Code，MNC)两部分组成。MCC可以设置为999，或者运营商自己设定取值。
②非独立组网非公有网络(Public network integrated non-public networks，PNI-NPN)：又可以称为公共网络集成NPN，可以使用PLMN ID，以及闭合接入组标识(Cell Access Group，CAG ID)进行标识。其中PLMN ID为运营商使用的普通PLMN ID。为了简化PNI-NPN，可以直接将非独立组网非公有网络称为CAG。
NPN仅允许有授权的终端设备进行正常接入，例如，当终端设备存在某个NPN的授权信息(subscription)时，该终端设备才允许以正常态(camped normally)接入该NPN。终端设备接入NPN后，网络设备将会对该终端设备进行鉴权，以确保该终端设备是具有该NPN授权的。
在一些特殊的情况下，非公网络可以通过网络模式设置或者无线接入网(Radio Access Network，RAN)共享，允许非授权终端设备的接入。
(6)无线接入网共享：一个小区可以支持NPN以及公共网络共享使用。例如电信与联通可以共享一个小区(相同的频点+相同的PCI)，通过不同的PLMN ID加以区分这两种网络。由于一个小区仅广播一套系统信息，小区的广播信息中的PLMN列表内可能包含该小区能够共享的所有网络，PLMN列表可以包括不同运营商的PLMN，等效PLMN(EPLMN)，不同类型的非公网络SNPN/CAG等。在无线接入网共享的场景下，一个小区最多可以设置12个条目，每个条目可以为普通PLMN、SNPN或CAG。对于不同运营商的部署，或者运营商不同PLMN范围的部署，有时相近地理范围的多个小区可以使用相同的SNPN或CAG。
(7)终端设备仅支持NPN：是指终端设备当前只能支持NPN。终端设备硬件不具有支持NPN的能力，那么就表示该终端设备始终无法支持NPN。终端设备还可能保存有模式信息，例如：“仅允许工作在非公网络”模式与“允许工作在公共网络”模式。如果终端设备处于“仅允许工作在非公网络”模式，则该终端设备不能接入在公共网络中。如果终端设备处于“允许工作在公共网络”模式，则该终端设备可以在公共网络与非公网络之间选择其中一个接入。
对于SNPN，终端设备可以设置为SNPN access mode的专有接入模式，即此时该模式的终端设备只能接入SNPN网络，无法接入公共网络以及其它NPN；
对于CAG，终端设备可以接收仅支持CAG指示(CAG-only indicator)，并设置为CAG-only模式，该CAG-only模式下的终端设备只能在签约CAG列表(allowed CAG list)中选择小区接入，才能处于正常接入小区(suitable cell)的状态。
(8)物理小区标识(Physical Cell Identifier，PCI)：终端设备根据PCI区分不同小区的无线信号。LTE系统提供504个PCI，网络配置时，为小区配置0～503之间的一个号码。LTE小区搜索流程中通过检索主同步序列(Primary Synchronization Signal，PSS)、辅同步序列(Secondary Synchronization Signal，SSS)，二者相结合确定小区的PCI，其中PSS共有3种可能性，SSS共有168种可能性。NR中提供的PCI的总数量多于LTE系统中的数量。
(9)PCI范围：在LTE系统中，为了减少终端设备自动搜索与测量等操作的耗电，在同频系统信息中加入了闭合接入小区标识范围(csg-PhysCell Id Range)的限制，设置了闭合模式的CSG小区可以使用的PCI范围。
下面对本公开涉及的现有技术进行介绍。
针对LTE中，服务小区会广系统信息，系统信息包括同频小区的PCI范围。终端设备中预存有自身签约或注册的授权信息，授权信息包括终端设备能够支持的网络的PLMN ID等。终端设备在进行小区重选的过程中，可以根据服务小区广播的邻区的PCI范围，选择测量该PCI范围所对应的小区进行测量。终端设备在选择测量某个小区之后，可能由于该小区无法支持终端设备所支持的网络，导致终端设备无法接入该小区。因此，终端设备需要再次对其它小区进行测量，直到成功接入小区，这样一来，在小区重选过程中，终端设备可能需要进行多次测量，导致终端设备的耗电量较大。
下面对上述现有技术选择小区的过程进行示例说明。各个小区支持的网络ID如下表1所示。
表1
Figure PCTCN2020109565-appb-000001
请参照表1，Normal表示公共网络；PCI1对应的小区支持公共网络，该公共网络的网络标识为PLMN1，PCI1的小区支持NPN中的CAG和PLMN，CAG的网络标识为PLMN2+CAG1，PLMN的网络标识为PLMN3+NID1，依次类推。
针对仅支持NPN的终端设备，可以根据服务小区的系统信息，确定存在PCI2-PCI4对应的小区。终端设备仅与PLMN2签约，而未与PLMN3签约，如果终端设备误选择PCI3对应的小区，并对该小区进行测量，但是该小区由于并不支持PLMN2，因此终端设备最终无法成功接入该小区，那么终端设备需要继续测量其它小区，直到成功接入对应的小区，在选择小区过程中，由于终端设备测量范围较大，因此终端设备的电量消耗较大。
鉴于此，本公开实施例提供一种小区选择方法，本公开实施例可以应用于但不限于第五代新空口(5 th new radio，5G NR)系统，还可以应用于LTE系统，长期演进高级(long term evolution-advanced，LTE-A)系统、增强的长期演进技术(enhanced long term evolution-advanced，eLTE)等通信系统中，也可能后续扩展到如无线保真(wireless fidelity，WiFi)、全球微波互联接入(worldwide interoperability for microwave access，wimax)、未来无线通信系统以及3GPP等相关的蜂窝系统中。
请参照图1，表示本公开实施例的应用场景，也可以理解为通信系统架构，该通信系统架构包括网络设备110和终端设备120，需要说明的是，本公开实施例中不限定图1中所示通信系统中终端设备120和网络设备110的个数。
具体的，终端设备120处于空闲态时，服务小区对应的网络设备110可以广播系统信息，系统信息携带有各个频点对应的PCI列表，每个频点的PCI列表包括该频点上的私有小区集合支持的NPN的至少一个网络标识，以及至少一个网络标识中每个网络标识关联的至少一个PCI。
终端设备120获取到该网络设备110广播的系统信息之后，可以根据该系统信息，排除一些无法支持自身所注册或签约的网络的小区，终端设备120后续无需对这些小区进行测量，从而可以相对减少终端设备120的测量和搜索范围，减少终端设备120在小区选择过程中的耗电量。
在图1论述的应用场景的基础上，下面对本公开实施例涉及的小区选择的方法进行详细介绍。请参照图2，该方法包括：
S201，网络设备110广播系统信息，系统信息携带PCI列表；
S202，终端设备120根据PCI列表，选择小区。
本公开实施例中，系统信息包括至少一个频点上的PCI列表，每个频点上的PCI列表包括频点上的私有小区集合的PCI，以及私有小区集合中各个私有小区对应支持的NPN的至少一个网络标识。可以进一步理解为每个频点都有该频点上所对应的PCI列表，每个频点上的PCI列表中包括在该频点上的私有小区集合支持的NPN的网络标识，以及支持的NPN的网络标识下的私有小区的PCI。PCI列表中的网络标识用于标识一种网络，网络标识可以是NPN的网络类型标识，也可以是NPN的PLMN标识，也可以是网络类型标识和PLMN标识。网络标识关联的至少一个PCI可以进一步理解为至少一个PCI对应的小区支持该网络标识所表示的网络。
其中，不同频点上的PCI列表中的PCI可以完全相同，也可以完全不同，也可以部分相同，本文不做具体限制。至少一个频点包括同频频点和/或异频频点，可以进一步理解为网络设备110可以广播同频频点上的PCI列表，也可以广播异频频点上的PCI列表，也可以广播同频频点上的PCI列表和异频频点上的PCI列表。应当说明的是，本公开中的异频和同频均是相对于终端设备120当前服务小区所在的频点而言，且同频和异频涉及的是服务小区的邻区中的小区。
例如，频点1对应的PCI列表中涉及的PCI为PCI1-5，频点2对应的PCI列表中涉及的PCI为PCI1-6。
其中，且每个频点上的PCI列表中的所有PCI中任一PCI和该频点对应的支持公共网络的小区的所有PCI中任一PCI不相同，可以理解为在该频点上的支持公共网络的小区与在该频点上的私有小区不共享PCI。本公开实施例中支持公共网络的小区包括仅支持公共网络的小区，以及同时支持公共网络和私有网络的小区。
下面以某一频点上的PCI列表为例，对PCI列表中涉及的具体内容进行分情况说明。
情况一：
PCI列表包括至少一个PLMN标识，以及至少一个PLMN标识中每个标识关联的至少一个PCI。
具体的，网络设备110获得在该频点上邻区内的私有小区集合支持的PLMN标识，以及每个PLMN标识下关联的至少一个PCI。每个PLMN标识下关联的至少一个PCI可以理解为支持该PLMN标识对应的网络的私有小区的PCI的集合。
情况一中的第一种子情况：
不同PLMN标识下关联的至少一个PCI不重叠。
具体的，不重叠可以理解为任意两个PLMN标识中，一PLMN标识下关联的PCI，和另一PLMN标识下关联的PCI不存在相同的PCI。
请参照图3，表示一种PCI列表的示例，该PCI列表包括三个PLMN标识，以及三个 PLMN标识下各个PLMN关联的PCI。PLMN2关联PCI3-PCI8，PLMN3关联的为PCI1-PCI2，PCI3-PCI8和PCI1-PCI2之间没有重叠。
情况一中的第二种子情况：
不同PLMN标识下关联的至少一个PCI存在重叠。
具体的，存在重叠可以理解为两个不同的PLMN标识中，一PLMN标识关联的至少一个PCI存在与另一PLMN标识关联的至少一个PCI相同的PCI。某些私有小区可能可以支持多种PLMN标识，那么该私有小区的PCI会关联在不同的PLMN标识下，也就是说，不同的PLMN标识下可能会关联相同的PCI。
针对情况一中的第二种子情况：
在一种可能的实施例中，当第一PLMN标识关联的PCI和第二PLMN标识关联的PCI完全重合时，合并表示第一PLMN标识与第一PLMN标识关联的PCI、以及第二PLMN标识与第二PLMN标识关联的PCI。
具体的，当两个不同PLMN标识关联的PCI完全重合时，可以将两个PLMN标识进行合并表示，如果有第三PLMN标识关联的PCI和第二PLMN标识关联的PCI完全重合，则可以合并表示第一PLMN标识与第一PLMN标识关联的PCI、以及第二PLMN标识与第二PLMN标识关联的PCI、以及第三PLMN标识与第三PLMN标识关联的PCI。合并表示例如在PCI列表中以一个条目表示。由于网络设备110每次下发的条目的数量是有限的，因此将两条信息进行合并表示，相对可以节省网络设备110的信令开销。
例如，请参照图4，表示一种PCI列表的示例，PLMN1关联PCI1-5，PLMN4关联的PCI1-5，可以理解为PLMN1关联的PCI和PLMN2关联的PCI完全重合，因此可以将PLMN1和PLMN1关联下的PCI1-PCI5，PLMN1和PLMN4关联下的PCI1-PCI5合并表示，同理，PLMN3、PLMN5和PLM6关联下的PCI10-PCI12完全重合，可以将PLMN3、PLMN5和PLM6关联下的PCI10-PCI12合并表示。
情况二：
PCI列表包括至少一个网络类型标识，以及至少一个网络类型标识中每个网络类型标识关联的至少一个PCI。
具体的，网络类型标识用于指示当前的NPN的具体网络类型，网络类型标识包括独立组网非公有网络SNPN或非独立组网非公有网络PNI-NPN。至少一个网络类型标识中每个网络类型标识关联的至少一个PCI，可以理解为能够支持该网络类型标识所对应的网络的所有小区的PCI的集合。
在一种可能的实施例中，SNPN关联的至少一个PCI和PNI-NPN关联的至少一个PCI存在重叠。
具体的，例如一个小区同时支持SNPN和PNI-NPN两种类型的NPN，那么该小区对应的PCI属于SNPN关联的至少一个PCI，也属于PNI-NPN关联的至少一个PCI。存在重叠可以理解为SNPN关联的至少一个PCI和PNI-NPN关联的至少一个PCI存在相同的PCI，可以是SNPN关联的至少一个PCI和PNI-NPN关联的至少一个PCI完全重叠，也可以是SNPN关联的至少一个PCI和PNI-NPN关联的至少一个PCI部分重叠。
例如，请参照图5，表示一种PCI列表的示例。PCI列表包括SNPN对应的网络类型标识(如图5中的SNPN)，以及与该网络类型标识关联的PCI(如图5中所示的PCI1-5)，PCI还包括PNI-NPN对应的网络类型标识(也就是图5中的PNI-NPN)，以及与该网络类 型标识关联的PCI(也就是图5中所示的PCI3-8)。
情况三：
PCI列表包括至少一个PLMN标识，至少一个网络类型标识，以及PCI。
情况三中PCI列表可以包括如下两种情况，下面进行具体说明。
情况三中的第一种子情况：
PCI列表包括至少一个网络类型标识、至少一个网络类型标识中每个网络类型标识关联的PLMN标识，以及至少一个PLMN标识中每个PLMN标识关联的至少一个PCI。
例如，请参照图6，一种PCI列表的示例，该PCI列表包括SNPN和PNI-NPN，SNPN关联的PLMN包括PLMN1和PLMN3，PLMN1关联的PCI为PCI1-PCI5，PLMN3关联的PCI为PCI1-PCI5。
情况三中的第二种子情况：
PCI列表包括至少一个PLMN标识、至少一个PLMN关联的至少一个网络类型标识，以及至少一个网络类型中每个网络类型标识关联的至少一个PCI。
例如，请参照图7，表示一种PCI列表，该PCI列表包括PLMN1、PLMN2和PLMN3等，PLMN1关联SNPN和PNI-NPN两种类型，PLMN1对应的SNPN下关联PCI1-5，PLMN1对应的PNI-NPN关联的为PCI1-5。
情况四：
PCI列表包括至少一个PLMN标识，以及至少一个PLMN标识中每个PLMN标识绑定的网络标识码NID或闭合接入组标识CAG ID。
具体的，针对SNPN，除了包括PLMN标识之外，网络标识还可以包括NID，因此PCI列表可以包括PLMN标识绑定的NID。针对PNI-NPN，除了包括PLMN标识之外，网络标识还可以包括与PLMN标识绑定的CAG ID，因此，PCI列表中的网络标识可以包括与PLMN标识绑定的NID，或者与PLMN标识绑定的CAG ID。
PCI列表包括PLMN标识绑定的NID，该PCI列表中可能没有携带NPN的网络类型标识，在一种可能的实施例中，可以基于NID或CAG ID，区分出各个PLMN标识所对应的网络类型。
例如，请参照图8，表示一种PCI列表，该PCI列表包括PLMN1，PLMN1绑定的NID1，该PLMN1+NID1关联PCI1-5。
情况五：
PCI列表包括至少一个网络类型标识、至少一个PLMN标识，以及至少一个PLMN标识中每个PLMN标识绑定的网络标识码NID，以及每个PLMN标识关联的PCI，或者PCI列表包括至少一个网络类型标识、至少一个PLMN标识，以及至少一个PLMN标识中每个PLMN标识绑定的闭合接入组标识CAG ID，以及每个PLMN标识关联的PCI。
情况五中的第一种子情况：
PCI列表包括至少一个网络类型标识、至少一个网络类型标识中每个网络类型标识关联的至少一个PLMN标识，以及至少一个PLMN标识中每个PLMN标识绑定的网络标识码NID或CAG ID，以及每个PLMN标识关联的PCI。
例如，请参照图9，表示一种PCI列表，SNPN关联至少一个PLMN标识，每个PLMN标识绑定NID，每个PLMN标识关联PCI。
情况五中的第二种子情况：
PCI列表包括至少一个PLMN标识、至少一个PLMN标识中每个PLMN标识关联的至少一个网络类型标识，以及至少一个网络类型标识中每个PLMN标识绑定的网络标识码NID或CAG ID，以及每个PLMN标识关联的PCI。
情况五中的第一种子情况和情况五中第二种子情况中PCI列表包括的信息相同，区别在于各个信息在PCI列表中的顺序有所不同。
无论PCI列表具体是前文论述的哪一种，在一种可能的实施例中，支持的NPN的网络标识下的私有小区集合的至少一个PCI可以是一个连续范围的PCI，可以进一步理解为支持一种NPN的网络标识下的私有小区集合对应的私有小区集合中的PCI是连续的。
在网络设备110广播该系统信息之后，终端设备120获取该系统信息，执行S202，根据PCI列表，选择小区。
具体的，网络设备110广播至少一个频点中每个频点的PCI列表，终端设备120在获得每个频点的PCI列表之后，可以选定某个频点，根据该选定频点上的PCI列表，确定测量该选定频点上的哪些小区，进而选择小区。终端设备120可以从至少一个频点上选择一个频点，根据该选定频点上的PCI列表，再选择小区。如果终端设备120在该频点上没有选择出合适的小区，又可以在至少一个频点上其它频点上选择频点，依次类推。终端设备120从至少一个频点上选择一个频点时，可以根据至少一个频点中各个频点的预设优先级进行选择，例如终端设备120可以先从至少一个频点中选择优先级高的频点，将优先级最高的频点作为选定频点。
应当说明的是，至少一个频点中的任一频点在被终端设备120选定之后，都可以称为选定频点。下面对终端设备120根据选定频点上的PCI列表中，选择小区的过程进行示例说明。
针对前文中的情况一：
当系统信息包括至少一个PLMN标识，以及至少一个PLMN标识中每个标识关联的至少一个PCI时，终端设备120在该选定频点上选择小区的方式具体如下：
A1：若终端设备120当前不支持NPN，终端设备120在选定频点上从私有小区集合之外的小区中选择小区。
具体的，终端设备120当前不支持NPN包括终端设备120本身不支持NPN，和终端设备120当前被配置为不支持NPN这两种情况，终端设备120当前不支持NPN表示终端设备120当前只支持公共网络，如前文论述的内容，PCI列表中包括的是私有小区集合对应的PCI，因此终端设备120可以在选定频点上邻区内从除了私有小区集合之外的小区中选择小区。在选定频点上从除了私有小区集合之外的小区可以理解为频点为选定频点，且不属于私有小区的小区。
在本公开实施例中，由于终端设备120可以根据网络设备120的系统信息，排除在选定频点上的PCI列表中所有PCI对应的私有小区，可以相对减少终端设备120后期需要测量的小区的数量，可以相对减少终端设备120的测量次数，减少终端设备120的耗电量。
A2：若终端设备120当前支持NPN，终端设备120可以从选定频点上的PCI列表的私有小区集合中，确定与终端设备120支持的PLMN标识匹配的私有小区，并从确定出的与终端设备120支持的PLMN标识匹配的私有小区，以及在选定频点上从除了私有小区集合之外的小区中选择小区。
具体的，终端设备120当前支持NPN表示终端设备当前仅支持NPN，或者终端设备 支持NPN以及公共网络，因此终端设备120可以在选定频点上选择私有小区集合中，与当前支持的NPN的PLMN标识匹配的私有小区，匹配可以理解为该私有小区支持该PLMN标识对应的小区。但是除了私有小区集合之外，其它支持公共网络的小区也可能支持NPN，因此终端设备120还可以从除了私有小区集合之外的小区中选择小区，进而终端设备120可以在选定频点上的私有小区集合中与当前支持的NPN匹配的PLMN标识的私有小区，以及除了私有小区集合之外的小区中，选择小区。
当终端设备120仅支持SNPN时，终端设备120仅支持SNPN表示该终端设备120只能支持NPN，且仅能支持NPN中的SNPN。因此，终端设备120可以排除不支持SNPN对应的PLMN标识的私有小区，从除了不支持SNPN对应的PLMN标识的私有小区之外的小区中选择小区。
当终端设备120仅支持PNI-NPN时，终端设备120可以排除不支持PNI-NPN对应的PLMN标识的私有小区，从除了不支持PNI-NPN对应的PLMN标识的私有小区之外的小区中选择小区。
当终端设备120支持SNPN和PNI-NPN时，终端设备120可以在支持SNPN对应的PLMN标识的私有小区，以及支持PNI-NPN对应的PLMN标识的私有小区，以及从除了私有小区集合之外的小区中选择小区。
本公开实施例中，由于终端设备120排除了不支持当前的终端设备所支持的PLMN标识的私有小区，缩小了终端设备120测量的小区范围，因此可以节省终端设备120的电量。
例如，继续参照图3，终端设备120支持PLMN1，那么终端设备120可以根据图3的PCI列表，排除图3中不支持PLMN1对应的小区，确定出不支持PLMN1的小区为PCI6-8，因此终端设备120无需对这些小区进行测量。
针对前文中的情况二：
当系统信息包括PCI列表包括至少一个网络类型标识，以及至少一个网络类型标识中每个网络类型标识关联的至少一个PCI时，终端设备120选择小区的方式具体如下：
B1：若终端设备120当前不支持NPN，则从选定频点上从除了私有小区集合之外的小区中，选择小区。
具体的，终端设备120当前不支持NPN的情况可以参照前文论述的内容，此处不再赘述。终端设备120当前不支持NPN，由于PCI列表对应的私有小区集合仅包括支持NPN的小区，因此终端设备120可以从选定频点上从除了私有小区集合之外的小区中，选择小区。
在本公开实施例中，由于终端设备120可以根据网络设备120的系统信息，排除PCI列表中所有PCI对应的私有小区，可以相对减少终端设备120后期测量的小区范围，可以相对减少终端设备120的测量次数，节省终端设备120的耗电量。
B2：若终端设备120当前仅支持SNPN或当前仅支持PNI-NPN，则确定与自身支持的网络类型对应的网络类型标识匹配的私有小区，从确定出的与自身支持的网络类型对应的网络类型标识匹配的私有小区，以及选定频点上从除了私有小区集合之外的小区中选择。
具体的，当终端设备120当前仅支持SNPN时，终端设备120确定与自身支持的网络类型SNPN匹配的私有小区，从确定出的与自身支持的网络类型SNPN匹配的私有小区，以及选定频点上从除了私有小区集合之外的小区中选择小区。
当终端设备120当前仅支持PNI-NPN时，终端设备120确定与自身支持的网络类型 PNI-NPN匹配的私有小区，从确定出的与自身支持的网络类型PNI-NPN匹配的私有小区，以及选定频点上从除了私有小区集合之外的小区中选择小区。
当终端设备120支持SNPN和PNI-NPN时，终端设备120可以在支持SNPN对应的私有小区，以及支持PNI-NPN对应的私有小区，以及选定频点上从除了私有小区集合之外的小区中选择小区。
例如，请继续参照图5，终端设备120仅支持SNPN，那么终端设备在获得该系统信息之后，可以根据该系统信息，排除不支持SNPN对应的私有小区(也就是图5中对应的PCI6-8对应的小区)，从除了不支持SNPN对应的私有小区(也就是图5中对应的PCI6-8对应的小区)的小区中，选择小区。
针对前文中的情况三：
当PCI列表包括至少一个网络类型标识、至少一个网络类型标识中每个网络类型标识关联的PLMN标识，以及至少一个PLMN标识中每个PLMN标识关联的PCI时，终端设备120选择小区的方式具体如下：
C1：若终端设备120当前不支持NPN，终端设备120可以从选定频点上从除了私有小区集合之外的小区中，选择小区。
具体的，终端设备120当前不支持NPN可以参照前文论述的内容，此处不再赘述。如果终端设备120当前只支持公共网络，那么终端设备120可以除了各个频点对应的PCI列表之外的小区中，去选择小区。
C2：若终端设备120当前支持NPN，终端设备120可以根据选定频点的PCI列表，从私有小区集合中，筛选出与终端设备120支持的NPN的网络类型标识匹配的，且与终端设备120支持的NPN的PLMN标识匹配的私有小区，终端设备120选定频点上从除了私有小区集合之外的小区，以及筛选出的私有小区中选择小区。
具体的，终端设备120可以从PCI列表中去选择与当前的网络标识匹配的私有小区，除此之外，支持公共网络的小区可能同时还支持NPN，因此终端设备120还可以从这些支持公共网络的小区中去选择小区。
当终端设备120支持SNPN时，终端设备120可以从选定频点的PCI列表中，筛选出与终端设备120支持的NPN的SNPN网络类型标识匹配的私有小区，以及从除了私有小区集合之外的小区中选择小区。
当终端设备120支持PNI-NPN时，终端设备120可以从选定频点的PCI列表中，筛选出与终端设备120支持的NPN的PNI-NPN网络类型标识匹配的私有小区，以及从除了私有小区集合之外的小区中选择小区。
例如，请继续参照图6，终端设备120当前支持SNPN，终端设备120可以从PCI列表中，筛选出与不支持SNPN的小区，从图6所示的PCI列表中确定出为PCI9-10，因此终端设备120从除了PCI9-10对应的小区中去筛选小区。
针对前文中的情况四：
当系统信息包括PCI列表包括至少一个PLMN标识，以及至少一个PLMN标识中每个PLMN标识绑定的网络标识码NID时，终端设备120选择小区的方式具体如下：
D1：若终端设备120当前不支持NPN，则终端设备120从选定频点的PCI列表中除了私有小区集合之外的小区中选择小区。
D2：若终端设备120当前支持NPN，则终端设备120从与自身支持PLMN标识和PLMN 标识绑定的网络标识码NID匹配的小区中，以及除了私有小区集合之外的小区中，选择小区。
当PCI列表包括至少一个PLMN标识，以及至少一个PLMN标识中每个PLMN标识绑定的闭合接入组标识CAG ID时，终端设备120选择小区的方式具体如下：
D3：若终端设备120当前不支持NPN，则终端设备120从除了私有小区集合之外的小区中选择小区。
D4：若终端设备120当前支持NPN，则终端设备120从与自身支持PLMN标识和PLMN标识绑定的网络标识码NID匹配的小区中，以及从除了私有小区集合之外的小区中，选择小区。
例如，请继续参照图7，终端设备120支持SNPN，且支持PLMN2，那么终端设备120根据图7确定PCI1-2、PCI9-10所示的小区无法支持终端设备120当前所支持的网络，因此终端设备120可以从除了PCI1-2、PCI9-10之外的小区中去选择小区。
针对前文中的情况五：
当系统信息包括PCI列表包括至少一个PLMN标识，以及至少一个PLMN标识中每个PLMN标识绑定的网络标识码NID，或者PCI列表包括至少一个PLMN标识，以及至少一个PLMN标识中每个PLMN标识绑定的闭合接入组标识CAG ID时，终端设备120选择小区的方式具体如下：
当系统信息包括PCI列表包括至少一个PLMN标识，以及至少一个PLMN标识中每个PLMN标识绑定的网络标识码NID：
E1：当终端设备120当前不支持NPN，则从选定频点上从除了私有小区集合之外的小区中，选择小区；
E2：若终端设备120当前支持NPN，则根据PCI列表，从私有小区集合中，筛选出与终端设备120支持的NPN的网络类型标识匹配的，与终端设备120支持的NPN的PLMN标识匹配，且与每个PLMN标识绑定的闭合接入组标识NID匹配的小区，并从筛选出的小区，以及选定频点上从除了私有小区集合之外的小区中选择小区。
当系统信息包括PCI列表包括至少一个PLMN标识，以及至少一个PLMN标识中每个PLMN标识绑定的CAG ID时：
E1：当终端设备120当前不支持NPN，则从选定频点上从除了私有小区集合之外的小区中，选择小区；
E2：若终端设备120当前支持NPN，则根据PCI列表，从私有小区集合中，筛选出与终端设备120支持的NPN的网络类型标识匹配的，与终端设备120支持的NPN的PLMN标识匹配，且与每个PLMN标识绑定的CAG ID匹配的小区，并从筛选出的小区，以及选定频点上从除了私有小区集合之外的小区中选择小区。
例如，请继续参照图9，终端设备120当前仅支持PNI-NPN，且PLMN3+CAG ID4对应的网络，因此终端设备120可以根据图9对应的PCI列表，确定不支持该终端设备120的小区PCI为PCI1-8，因此终端设备120可以从除了PCI1-8的私有小区中，选择小区。
在针对情况四和情况五中所示的实施例中，由于PCI列表中包括PLMN标识匹绑定的NID或CAG ID，因此终端设备120可以根据自身存储的授权信息，排除更多的小区，且能够读取被测量的小区，确定该小区是否支持终端设备对应的网络，进一步减少终端设备120读取其它小区的系统信息的次数，减少终端设备120的测量次数，节省终端设备120 的耗电量。
在终端设备120针对选定频点进行小区选择之后，可以测量选择出的小区，确定驻留的小区。
