技术领域
本发明涉及通信技术领域，尤其涉及一种小区选择方法、终端及网络设备。
背景技术
目前，5G NR系统中具体包括3种连接状态：无线资源控制(Radio Resource Control，RRC)空闲(RRC IDLE)态、RRC连接(RRC CONNECTED)态以及RRC激活态(RRC Inactive)，终端可以在上述的三种状态间进行转换。针对非RRC激活态，由于只有部分LTE系统小区(能够连接到5G核心网的小区)以及全部5G NR系统小区支持非激活态信令配置和相关信令流程，因此，当非激活态的终端需要连接到支持非激活态的小区时，则需要从终端所能连接的小区中选择出支持非激活态的小区。
然而，当非激活态的终端需要连接到支持非激活态的小区时，目前还没有针对非激活态的终端的小区选择或重选方案。
发明内容

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
本文中术语“和/或”，仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，本文中字符“/”，一般表示前后关联对象是一种“或”的关系；在公式中，字符“/”，表示前后关联对象是一种“相除”的关系。如果不加说明，本文中的“多个”是指两个或两个以上。
为了便于清楚描述本发明实施例的技术方案，在本发明的实施例中，采用了“第一”、“第二”等字样对功能或作用基本相同的相同项或相似项进行区分，本领域技术人员可以理解“第一”、“第二”等字样并不对数量和执行次序进行限定。
本发明实施例中，“示例性的”或者“例如”等词用于表示作例子、例证或说明。本发明实施例中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言，使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。在本发明实施例中，除非另有说明，“多个”的含义是指两个或者两个以上。
目前，5G NR系统中包括3种连接状态：RRC空闲态、RRC连接态以及RRC激活态。
针对非激活态的终端，目前还没有针对非激活态的终端的小区选择或重选方案。
虽然终端可以在上述的三种状态间进行转换，但空闲态的终端的小区选择或重选方案并不能适用于非激活态的终端。首先，由于只有部分长期演进(Long Term Evolution，LTE)系统小区(能够连接到5G核心网的小区)以及全部5G NR系统小区支持非激活态信令配置和相关信令，因此，当终端选择或重选到一个不支持非激活态的小区(例如连接到EPC的LTE小区)，将无法支持非激活态下特有过程，例如RRC连接恢复/挂起，小数据包发送等。其次，非激活态的终端的接入层(access stratum，AS)上下文(context)有一定的区域内活动，该区域通常可以认为是网络设备为非激活态的终端配置的接入网跟踪区域(RNA Notification area，RNA)，当非激活态的终端重选到一个inter-RAT小区(例如，该小区是一个连接到EPC的LTE小区)，不在RNA范围内，终端的AS context将因无法在网络侧恢复而自动释放。
针对上述问题，本发明实施例提供一种小区选择方法、终端及网络设备，针对非激活态的终端，网络设备通过向终端发送第一指示信息，该第一指示信息用于指示允许或禁止非激活态的终端选择第一小区，从而使的非激活态的终端在小区选择和重选时，能够根据该第一指示信息的指示，确定出该非激活态的小区的候选小区，进而使得非激活态的终端尽可能的能够选择到一个支持非激活态和/或UE AS context有效的小区。
应注意的是，本发明实施例中的小区选择包括：初始小区的选择，和/或，小区的重选，这里的“选择”仅仅强调选择的动作，对于是初始小区的选择还是小区的重选，本发明对此不作限定。例如，第一指示信息用于指示允许或禁止非激活态的终端选择第一小区，也可以为，第一指示信息用于指示允许或禁止非激活态的终端重选第一小区。
本发明提供的技术方案可以应用于各种通信系统，例如，5G通信系统，未来演进系统或者多种通信融合系统等等。可以包括多种应用场景，例如，机器对机器(Machine to Machine，M2M)、D2M、宏微通信、增强型移动互联网(enhance Mobile Broadband，eMBB)、超高可靠性与超低时延通信(ultra Reliable&Low Latency Communication，uRLLC)以及海量物联网通信(Massive Machine Type Communication，mMTC)等场景。这些场景包括但不限于：终端与终端之间的通信，或网络设备与网络设备之间的通信，或网络设备与终端间的通信等场景中。本发明实施例可以应用于与5G通信系统中的网络设备与终端之间的通信，或终端与终端之间的通信，或网络设备与网络设备之间的通信。
图1示出了本发明实施例所涉及的通信系统的一种可能的结构示意图。如图1所示，该通信系统包括至少一个网络设备100(图1中仅示出一个)以及每个网络设备100所连接的一个或多个终端200。
其中，上述的网络设备100可以为基站、核心网设备、发射接收节点(TRNAsmission and Reception Point，TRP)、中继站或接入点等。网络设备100可以是全球移动通信系统(Global System for Mobile communication，GSM)或码分多址(Code Division Multiple Access，CDMA)网络中的基站收发信台(Base TRNAsceiver Station，BTS)，也可以是宽带码分多址(Wideband Code Division Multiple Access，WCDMA)中的NB(NodeB)，还可以是LTE中的eNB或eNodeB(evolutional NodeB)。网络设备100还可以是云无线接入网络(Cloud Radio Access Network，CRNA)场景下的无线控制器。网络设备100还可以是5G通信系统中的网络设备或未来演进网络中的网络设备。然用词并不构成对本发明的 限制。

实施例一：
图2示出了本发明实施例的提供的一种小区选择方法的流程示意图。该方法具体包括：
S201、网络设备向终端发送第一指示信息。
相应的，对端终端接收第一指示信息。
本发明实施例中的网络设备可以为图1所示通信系统中的网络设备，例如，基站；本发明实施例中的终端可以为图1所示的通信系统中的终端设备。
其中，上述的第一指示信息用于指示允许或禁止非激活态的终端选择第一小区。
示例性的，本发明实施例中的终端为非激活态的终端。
在本发明实施例中，上述第一指示信息可以携带在网络设备向终端发送的系统消息中。示例性的，上述系统消息可以是主信息块(MasterInformationBlock，MIB)，系统信息块类型1(SystemInformationBlockType1，SIB1)，剩余最小系统信息(Remaining Minimum System Information，RMSI)等。
S202、终端根据第一指示信息，确定非激活态的终端的候选小区。
在本发明实施例中，当第一指示信息用于指示允许非激活态的终端选择第一小区，则非激活态的终端根据第一指示信息将部分或全部第一小区作为非激活态的终端的候选小区，即上述的候选小区为第一小区中的部分或全部小区。
在本发明实施例中，当第一指示信息用于指示禁止非激活态的终端选择第一小区，则非激活态的终端根据第一指示信息不将第一小区作为非激活态的终端的候选小区，即上述的候选小区不包含第一小区。
在本发明实施例中，非激活态的终端在执行小区选择或重选过程中，会根据第一指示信息的作用不同，执行不同的操作。
在一种示例中，当第一指示信息用于指示禁止非激活态的终端选择第一小区，非激活态的终端会在一段时间内不将第一小区作为候选小区考虑。或者，当第一指示信息用于指示允许非激活态的终端选择第一小区，非激活态的终端会把该第一小区作为候选小区考虑。
可选的，网络设备向终端发送的第一指示信息具体可以有以下三种形式。具体的：
第一种形式：
网络设备直接指示第一指示信息。
示例性的，该第一指示信息为指示允许非激活态的终端选择第一小区的信息，或者指示禁止非激活态的终端选择第一小区的信息。
第二种形式：
网络设备向非激活态的终端发送RNA标识及该RNA标识对应的禁止(barred)信息(简称：bar信息)。
示例性的，上述的第一指示信息包括M个RNA标识，该第一指示信息用于指示允许或禁止非激活态的终端选择第一小区，该第一小区为M个RNA中每个RNA对应的第一小区，M为正整数，一个RNA对应至少一个小区，即一个RNA范围内包括至少一个小区。
在一种示例中，上述的RNA标识包括：本小区所属的RNA标识，和/或，邻小区所属的RNA标识。
在一种示例中，上述的M个RNA标识可以携带在系统消息中。
上述的RNA标识以RNA ID为例：
示例1：若第一指示信息中包含一个RNA ID以及相应的bar信息。假设该RNA ID＝1，则对应的bar信息包括但不限于以下2种组合：例1)RNA ID＝1，禁止；例2)RNA ID＝1，不禁止/允许(not Barred)。
示例2：若第一指示信息中包含多个RNA ID以及相应的bar信息。以2个RNA ID为例进行说明，假设这两个RNA ID分别为7和10，则对应的bar信息包括但不限于以下4种组合：例1)RNA ID＝7，barred；RNA ID＝10，barred；例2)RNA ID＝7，barred；RNA ID＝10，not Barred；例3)RNA ID＝7，not Barred；RNA ID＝10，barred；例4)RNA ID＝7，not Barred；RNA ID＝10，not Barred。
在这种形式下，相应的，非激活态的终端执行小区选择或重选的过程中，会根据第一指示信息的作用不同，执行不同的操作。具体的：
非激活态的终端会在一段时间内不把属于该M个RNA的小区作为候选小区考虑，或者，非激活态的终端会把属于该M个RNA的小区作为候选小区考虑。
第三种形式：
网络设备向非激活态的终端发送黑名单，用于辅助非激活态的终端进行小区选择。
示例性的，上述的第一指示信息包括黑名单，该黑名单包括至少一个第一小区的标识，上述的第一指示信息用于指示禁止非激活态的终端选择该至少一个第一小区。
在一种示例中，上述的黑名单可以携带在系统消息或RRC专用信令中。
示例性的，当上述的黑名单用于辅助非激活态的终端进行初始小区的选择，则上述的系统消息可以是：MIB，SIB1，RMSI等。当上述的黑名单用于辅助非激活态的终端进行小区冲选择，则上述的系统消息可以是：SIB3、SIB4、SIB5、系统消息新引入的SIBx以及其他系统信息(Other System Information，OSI)。
示例性的，上述的RRC专用信令可以是：RRC连接释放消息(RRC Connection Release)，RRC连接恢复消息(RRC Connection Resume)，RRC连接挂起消息(RRC Connection Suspend)，RRC连接重配置消息(RRC Connection Reconfiguration)等。
上述的系统消息示例以及RRC专用信令示例仅仅是一种说明，并不对系统消息以及RRC专用信令进行限制，本发明实施例对于系统消息以及RRC专用信令并不做限制。
在这种形式下，相应的，非激活态的终端执行小区选择或重选的过程中，会执行如下操作。具体的：
非激活态的终端执行小区选择或重选的过程中，会忽略黑名单中的第一小区，即不将黑名单中的第一小区作为候选小区。
应注意的是，在本发明实施例中，RRC专用信令优先于系统消息，即如果RRC信令提供了专用的黑名单，则非激活态的终端可以忽略系统消息中的黑名单。
本发明实施例提供一种小区选择方法，主要针对非激活态的终端，网络设备通过向终端发送第一指示信息，该第一指示信息用于指示允许或禁止非激活态的终端选择第一小区，从而使的非激活态的终端在小区选择和重选时，能够根据该第一指示信息的指示，确定出该非激活态的小区的候选小区，进而使得非激活态的终端尽可能的能够选择到一个支持非激活态和/或UE AS context有效的小区。
实施例二：
图3示出了本发明实施例提供的一种小区选择方法的流程示意图。本发明实施例主要针对第一指示信息中仅包含了K个RNA标识，且该第一指示信息并未有明显的bar信息来指示这K个RNA标识的用途的情况下的小区选择过程。
具体的，如图3所示，该方法包括如下步骤：
S301、网络设备向终端发送第一指示信息。
其中，上述的第一指示信息包括K个RNA标识，K为正整数。
示例性的，上述的K个RNA标识包括：初始小区选择终端检测到的小区所属的RNA标识或终端当前驻留小区的邻小区所属的RNA标识。
S302、网络设备为终端配置N个RNA标识。
相应的，对端终端接收N个RNA标识。
应注意的是，本发明实施例中的S301与S302之间没有明显步骤顺序，S302可以在S301之前执行，也可以在S301之后执行，或者也可以与S301同时执行，本发明对此不做限制。
可选的，在本发明实施例中，网络设备为非激活态的终端配置给非激活态的终端的RNA配置信息，其中，该RNA配置信息中包含N个RNA标识。
在本发明实施例中，若K个RNA标识中包含N个RNA标识中的X个RNA标识，则第一指示信息用于指示允许非激活态的终端选择第一小区，该第一小区为该X个RNA对应的小区。
在本发明实施例中，若K个RNA标识中不包含任一RNA标识，则第一指示信息用于指示禁止非激活态的终端选择第一小区，该第一小区为K个RNA对应的小区；K、N、X均为正整数，K、N大于或等于X。
应注意的是，本发明实施例中的K与M的数量可以相同也可以不相同，本发明对此不做限制。
举例说明，上述的RNA标识以RNA ID为例，假设第一指示信息中包含2个RNA ID，且这2个RNA ID分别为7和10，网络设备为非激活态的终端配置了3个RNA ID，这3 个RNA ID分别为分别为1，2，7。由于第一指示信息与网络设备为终端的RNA ID中都包含了RNA ID＝7，则该第一指示信息可以默认用于指示允许非激活态的终端选择RNA ID＝7的RNA对应的小区。而RNA ID＝10由于未在网络设备为终端的RNA ID中，则该第一指示信息可以默认用于指示禁止非激活态的终端选择RNA ID＝10的RNA对应的小区。
S303、终端根据第一指示信息，确定非激活态的终端的候选小区。
其中，上述的候选小区为第一小区中的部分或全部小区。
在这种形式下，相应的，非激活态的终端执行小区选择或重选的过程中，会根据第一指示信息的作用不同，执行不同的操作。具体的：
非激活态的终端会把包含在网络设备为终端配置的RNA ID的RNA ID的小区作为候选小区考虑，或者，非激活态的终端会在一段时间内不把未包含在网络设备为终端配置的RNA ID的RNA ID的小区作为候选小区考虑。
本发明实施例提供一种小区选择方法，主要针对非激活态的终端，网络设备通过向终端发送包含K个RNA标识的第一指示信息，以及为终端配置的N个RNA标识，从而使得非激活态的终端在第一指示信息中仅包含RNA标识时，可以基于第一指示信息所指示的RNA标识与网络设备为终端配置的RNA标识，来判定出允许或禁止非激活态的终端接入的第一小区，从而使的非激活态的终端在小区选择和重选时，能够确定出该非激活态的小区的候选小区，进而使得非激活态的终端尽可能的能够选择到一个支持非激活态和/或UE AS context有效的小区。
需要说明的是，本实施例二与实施例一相关的描述均可参照实施例一中的内容，这里不再赘述。

示例性的，对于小区的频率优先级高于或等于非激活态的终端当前驻留的服务小区的频率优先级的频率，执行步骤A1和A2，或步骤B：
步骤A1：如果高优先级频率小区或同等级优先级频率小区广播的部分或全部RNA ID包含在网络设备为终端配置的RNA ID中，则非激活态的终端将部分或全部RNA ID对应的小区作为候选小区考虑。
步骤A2：非激活态的终端将上述部分或全部RNA ID对应的小区作为候选小区考虑，进一步基于优先级参数计算小区信道质量是否符合预设重选准则。例如，高优先级频率小区的信道质量大于预设的门限，且持续时间超过预设的门限。
或者，

示例性的，对于小区的频率优先级小于非激活态的终端当前驻留的服务小区的频率优先级的频率。执行步骤C或步骤D。
步骤C：如果低优先级频率小区广播的部分或全部RNA ID包含在网络设备为终端配置的RNA ID中，且该部分或全部RNA ID中的一个或多个RNA ID对应的小区的RSRP大于服务小区的RSRP，则非激活态的终端将该部分或全部RNA ID中的一个或多个RNA ID对应的小区作为候选小区考虑，进一步基于优先级参数计算这些小区的信道质量是否符合预设重选准则。例如，高优先级频率小区的信道质量大于预设的门限，且持续时间超过预设的门限。
