具体实施方式
现结合附图和具体实施方式对本公开实施例进一步说明。
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开实施例相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。
需要说明的是，本公开的一个实施例中可以包括多个步骤；为了便于描述，这些个步骤被进行了编号；但是这些编号并非是对步骤之间执行时隙、执行顺序的限定；这些步骤可以以任意的顺序被实施，本公开实施例并不对此作出限定。
在5G NR中，注册区域(Registration area,RA)为跟踪区域(Tracking Area，TA)的集合,每个TA包括一个或多个小区，对应某个地理区域。每个TA通过跟踪区域标识(Tracking Area Identification，TAI)来确定，TAI包括公共陆地移动网(Public Land Mobile Network，PLMN)和跟踪区域码(Tracking Area Code,TAC)。网络侧通过广播系统消息的方式将PLMN和TAC发送给UE。网络侧为给UE配置多个TA，即配置TAI列表(TAI list)，该TAI列表包括网络侧为UE配置的多个TA。
当UE从TA1(即，跟踪区域1)移动到TA2(即，跟踪区域2)时，如果TA2不在网络侧为UE配置的TAI list中，UE需要发起TAU/RAU，从而网络侧能够为UE配置新的TAI list，以保证网络侧能够跟踪到UE。NTN小区的覆盖范围较大，在不同国家的边界处，NTN小区可能覆盖多个不同的国家，且国家交界处多为不规则形状。例如，在卫星移动到覆盖区域3的位置的情况下，其广播的TAC为TAC3，那么即使区域3涉及不同的国家，不同国家的UE所获取的TAC也均为TAC3。而对于不同的国家的UE，网络侧可能采取不同的接入策略，例如gNB需要为处于不同国家的UE选择不同的核心网接入。但是，网络侧不能通过UE上报的其对应的TAC来区分各UE所处的国家。
本公开实施例提供的发送跟踪区域码的方法以及确定跟踪区域码的方法特别适用于存在上述情况的NTN网络中，当然也适用于TN网络中。
本公开实施例提供了一种发送跟踪区域码的方法，该方法应用于基站设备。图1是根据一示例性实施例示出的一种发送跟踪区域码的方法的流程图，如图1所示，该方法包括：
步骤101，发送跟踪区域码的指示信息，所述指示信息用于指示至少一个跟踪区域码的适用范围。
在一实施方式中，基站设备例如在广播TAC时，发送TAC的指示信息。这里TAC的指示信息用于指示基站设备发送的TAC中至少一个TAC的适用范围。这里TAC的适用范围对应小区覆盖范围中的部分或全部。小区覆盖范围可以是广播TAC的基站设备所对应的小区覆盖范围。
在一实施方式中，基站广播一个TAC，并且发送指示信息，该指示信息用于指示该一个TAC的适用范围。在一实施方式中，基站广播多个TAC，并且发送指示信息，该指示信息用于指示多个TAC中部分TAC的适用范围。在一实施方式中，基站广播N个TAC，并且发送指示信息，该指示信息用于指示N-1个TAC的适用范围，N为大于或等于2的正整数。在一实施方式中，基站设备广播多个TAC，并向用户设备发送指示信息，该指示信息包括用于指示所有TAC的适用范围的信息，例如所有TAC各自的地理位置坐标的信息。
在该实施中，基站设备发送跟踪区域码的指示信息，该指示信息用于指示至少一个跟踪区域码的适用范围，从而基站设备发送的跟踪区域码的适用范围可以小于小区的覆盖范围，进而使得用户设备在接收到该指示信息后，能够基于该指示信息确定用户设备对应的TAC，实现处于同一个小区覆盖范围的用户设备可以使用不同的TAC。
本公开实施例提供了一种发送跟踪区域码的方法，该方法应用于基站设备，该方法包括：发送跟踪区域码的指示信息，所述指示信息用于指示至少一个跟踪区域码的适用范围，并且，所述跟踪区域码的适用范围小于或等于小区的覆盖范围。
在一实施方式中，基站设备广播一个TAC，并且发送指示信息，该指示信息用于指示该一个TAC的适用范围，该一个TAC的适用范围即为整个小区的覆盖范围。在一实施方式中，基站设备广播多个TAC，并且发送指示信息，该指示信息用于指示多个TAC中部分TAC的适用范围，其中每个TAC的适用范围均小于小区的覆盖范围。在一实施方式中，基站设备广播多个TAC，并向用户设备发送指示信息，该指示信息包括用于指示所有TAC的适用范围的信息，例如所有TAC各自的地理位置坐标的信息。
在一实施方式中，小区为NTN网络中的小区，当小区覆盖范围较大时，TAC的适应范围也可能较大。由于NTN小区的覆盖范围较大，若TAC的适应范围较大，则归属于不同国家的UE可能对应同一个TAC，这就使得网络侧难以通过UE上报的其对应的TAC来区分各UE所处的国家。但是由于TAC的适应范围小于小区的覆盖范围，即TAC的适应范围设置的较小，就能够避免上述归属于不同国家的UE对应同一个TAC所带来的问题。
本公开实施例提供了一种发送跟踪区域码的方法，该方法应用于基站设备；该方法可以独立被执行，也可以结合本公开实施例的任意一个其他实施例一起被执行。图2是根据一示例性实施例示出的一种发送跟踪区域码的方法的流程图，如图2所示，该方法包括：

在一实施方式中，基站设备通过系统消息和/或无线资源控制消息中的设定字段，向用户设备发送用于指示至少一个跟踪区域码的适用范围的指示信息。设定字段的位数可以根据需要设置，例如为1bit、2bit或更多，在此不做限制。
在一实施方式中，基站设备通过系统消息中的设定字段，向用户设备发送用于指示至 少一个跟踪区域码的适用范围的指示信息。在一实施方式中，基站设备通过无线资源控制消息中的设定字段，向用户设备发送用于指示至少一个跟踪区域码的适用范围的指示信息。在一实施方式中，基站设备通过系统消息和无线资源控制消息中的设定字段，向用户设备发送用于指示至少一个跟踪区域码的适用范围的指示信息，即基站设备均对系统消息和无线资源控制消息中的设定字段进行设置，并发送系统消息和无线资源控制消息。
在一实施方式中，跟踪区域码的适用范围小于或等于小区的覆盖范围。
基站设备将指示信息存在于系统消息和/或无线资源控制消息中具体位置，即设定字段的位置通知用户设备。也可以在标准中规定设定字段的位置。用户设备通过接收基站设备发送的系统消息和/或无线资源控制消息，并获取该系统消息和/或无线资源控制消息中设定字段的内容，便可获取上述指示信息。由此，用户设备通过该指示信息可以确定自身对应的TAC。
本公开实施例提供了一种发送跟踪区域码的方法，该方法应用于基站设备；该方法可以独立被执行，也可以结合本公开实施例的任意一个其他实施例一起被执行。该方法包括：发送跟踪区域码的指示信息，所述指示信息用于指示至少一个跟踪区域码的适用范围，并且，所述指示信息包括：用于指示所述跟踪区域码的适用范围对应于所述小区的覆盖范围的信息。

在一实施方式中，基站设备广播一个TAC：TAC1，基站设备将系统消息和/或无线资源控制消息中的设定字段设置为“0”，并向用户设备发送该系统消息和/或无线资源控制消息。这里设定字段“0”指示该TAC1的适用范围对应于整个小区的覆盖范围。
在一实施方式中，跟踪区域码的适用范围小于或等于小区的覆盖范围。
通过本实施例中的方法，在基站设备仅广播一个TAC的情况下，基站设备可以将TAC及指示信息发送给用户设备，并且无需告诉用户设备所发送TAC的适用范围的地理位置坐标，就可以使用户设备获取该TAC的适用范围，提高了信息的发送效率。
本公开实施例提供了一种发送跟踪区域码的方法，该方法应用于基站设备；该方法可以独立被执行，也可以结合本公开实施例的任意一个其他实施例一起被执行。该方法包括：发送跟踪区域码的指示信息，所述指示信息用于指示至少一个跟踪区域码的适用范围，并且，所述指示信息用于指示所述跟踪区域码的适用范围对应于所述小区的部分覆盖范围，所述小区的部分覆盖范围是从所述小区的覆盖范围中除去其它跟踪区域码的适用范围后的小区覆盖范围。
在一实施方式中，基站设备广播三个TAC：TAC1、TAC2、TAC3，向用户设备发送的指示信息包括：TAC1的适用范围的地理位置坐标和TAC2的适用范围的地理位置坐标，TAC3的适用范围的至少1bit的设定字段。这里的TAC3的适用范围的至少1bit的设定字段用于指示TAC3的适用范围为小区的覆盖范围中除去TAC1的适用范围和TAC2的适用范围后的小区覆盖范围。在上述实施方式中，每一个TAC的适用范围可以用1bit或多个bit进行指示，本公开实施例中并不对此作出限定。

在一实施方式中，基站设备广播一个TAC：TAC1，并向用户设备发送指示信息，该指示信息包括用于指示TAC1的适用范围的地理位置坐标的信息。
在一实施方式中，基站设备广播三个TAC：TAC1、TAC2、TAC3，并向用户设备发送指示信息，该指示信息包括用于指示TAC1、TAC2、TAC3各自的适用范围的地理位置坐标的信息。
在一实施方式中，跟踪区域码的适用范围小于或等于小区的覆盖范围。
通过本实施例中的方法，基站设备在广播TAC时，还会发送指示信息，该指示信息包括指示广播的所有TAC的使用范围的信息。用户设备在接收到基站设备发送的TAC及指示信息后，可以准确地确定各TAC的适应范围。
本公开实施例提供了一种发送跟踪区域码的方法，该方法应用于基站设备；该方法可以独立被执行，也可以结合本公开实施例的任意一个其他实施例一起被执行。该方法包括：发送跟踪区域码的指示信息，所述指示信息用于指示至少一个跟踪区域码的适用范围，响应于所述基站设备发送的跟踪区域码没有对应的指示信息，则所述跟踪区域码的适用范围对应于所述小区的部分覆盖范围，所述小区的部分覆盖范围是从所述小区的覆盖范围中除去其它跟踪区域码的适用范围后的小区覆盖范围。
在一实施方式中，基站设备广播N个跟踪区域码，并发送指示信息，该指示信息仅包括用于指示N-1个跟踪区域码的适用范围的信息，N为大于或等于2的正整数。此时，剩余一个跟踪区域码的适用范围对应于小区的部分覆盖范围，该部分覆盖范围是从小区的覆盖范围中除去对应有适用范围的指示信息的N-1个跟踪区域码的适用范围后的小区覆盖范 围。
在一实施方式中，基站设备广播三个TAC：TAC1、TAC2、TAC3，并向用户设备发送指示信息：TAC1和TAC2的适用范围的地理位置坐标。基站设备发送的指示信息不包括TAC3的适用范围。此情况中，TAC3的适用范围为小区的覆盖范围中除去TAC1的适用范围和TAC2的适用范围后的小区覆盖范围。
在一实施方式中，跟踪区域码的适用范围小于或等于小区的覆盖范围。
通过本实施例中的方法，基站设备广播多个TAC的情况下，基站设备发送的指示信息不包括指示其中一个TAC的适用范围的信息。但是，基站设备和用户设备通过在协议或标准中协商此情况下的该一个TAC的适用范围为小区的覆盖范围中除去其它跟踪区域码的适用范围后的小区覆盖范围。这样，用户设备仍然能够获取基站设备广播的所有TAC的适用范围，从而提高了信息的发送效率。
本公开实施例提供了一种发送跟踪区域码的方法，该方法应用于基站设备；该方法可以独立被执行，也可以结合本公开实施例的任意一个其他实施例一起被执行。该方法包括：发送一个TAC，且不发送该TAC的指示信息。

通过本实施例中的方法，基站设备在广播一个TAC的情况，无需发送任何指示信息，用户设备即可获取该一个TAC的适用范围，提高了信息的发送效率。

本实施例中，用户设备从基站设备接收TAC，确定各TAC的适用范围，并基于接收的TAC、确定的适用范围和该用户设备的所处的位置，来确定该用户设备对应的TAC。
在一实施方式中，用户设备从基站设备接收三个TAC：TAC1、TAC2、TAC3；用户设备确定TAC1的适用范围为AREA1，TAC2的适用范围为AREA2，TAC3的适用范围为AREA3；用户设备获取自身所处的位置信息，并确定用户设备当前位置位于AREA1的范围内，因此用户设备确定自己对应的TAC为AREA1对应的TAC1。
通过本实施例中的方法，用户设备能够准确地确定自己所对应的TAC，从而有助于网络，即基站设备能够确定UE更精确的位置。
本公开实施例提供了一种确定跟踪区域码的方法，应用于用户设备；该方法可以独立被执行，也可以结合本公开实施例的任意一个其他实施例一起被执行。图4是根据一示例性实施例示出的一种确定跟踪区域码的方法的流程图，如图4所示，该方法包括：

步骤403，基于所述指示信息，确定所述跟踪区域码的适用范围；
步骤404，基于所述跟踪区域码、所述跟踪区域码的适用范围和所述用户设备的位置信息，确定所述用户设备对应的跟踪区域码。
在本实施例中，用户设备不仅从基站设备接收TAC，还从基站设备接收用于指示至少一个TAC的适用范围的指示信息。用户设备基于从基站设备接收的指示信息来确定所接收的各TAC的适用范围，从而基于接收的TAC、确定的适用范围和该用户设备的所处的位置，来确定该用户设备对应的TAC。
通过本实施例中的方法，用户设备通过从基站设备接收的指示信息来准确地确定自己所对应的TAC，从而有助于网络，即基站设备能够确定用户设备更精确的位置。
本公开实施例提供了一种确定跟踪区域码的方法，应用于用户设备。该方法可以独立被执行，也可以结合本公开实施例的任意一个其他实施例一起被执行。图5是根据一示例性实施例示出的一种确定跟踪区域码的方法的流程图，如图5所示，该方法包括：
步骤501，从基站设备接收跟踪区域码；
步骤502，获取所述用户设备上预配置的跟踪区域码的指示信息，所述指示信息用于指示至少一个跟踪区域码的适用范围；
步骤503，基于所述指示信息，确定所述跟踪区域码的适用范围
步骤504，基于所述跟踪区域码、所述跟踪区域码的适用范围和所述用户设备的位置信息，确定所述用户设备对应的跟踪区域码。
在本实施例中，用户设备仅从基站设备接收TAC：TAC1、TAC2、TAC3。用户设备获取自身预配置的用于指示至少一个TAC的适用范围的指示信息。用户设备基于预配置的指示信息来确定所接收的各TAC的适用范围：TAC1的适用范围为AREA1，TAC2的适用范围为AREA2，TAC3的适用范围为AREA3。用户设备基于接收的TAC、确定的适用范围和该用户设备的所处的位置，来确定该用户设备对应的TAC为TAC1。
这里预配置的指示信息可以是预配置于用户设备的存储装置中、用于用户设备的全球用户识别卡(Universal Subscriber Identity Module，USIM)中、用于用户设备的嵌入式用户识别卡(Embedded Subscriber Identity Module，eSIM)中。

在一实施方式中，用户设备从基站设备接收一个TAC：TAC1，确定该一个TAC的适用范围为整个小区的覆盖范围，基于该一个TAC，确定的适用范围以及用户设备的所处的位置，来确定该用户设备对应的TAC为TAC1，此情况中，TAC的适用范围等于小区的覆盖范围。在一实施方式中，用户设备从基站设备接收多个TAC，确定各TAC的适用范围，并基于该多个TAC，确定的适用范围以及用户设备的所处的位置，来确定该用户设备对应的TAC。其中，每个TAC的适用范围均小于小区的覆盖范围。
在一实施方式中，小区为NTN网络中的小区，当小区覆盖范围较大时，TAC的适应范围也可能较大。由于NTN小区的覆盖范围较大，若TAC的适应范围较大，则归属于不同国家的UE可能对应同一个TAC，这就使得网络侧难以通过UE上报的其对应的TAC来区分各UE所处的国家。但是由于TAC的适应范围小于小区的覆盖范围，即TAC的适应范围设置的较小，就能够避免上述归属于不同国家的UE对应同一个TAC所带来的问题。
本公开实施例提供了一种确定跟踪区域码的方法，应用于用户设备。该方法可以独立被执行，也可以结合本公开实施例的任意一个其他实施例一起被执行。图6是根据一示例性实施例示出的一种确定跟踪区域码的方法的流程图，如图6所示，该方法包括：

在一实施方式中，跟踪区域码的适用范围小于或等于小区的覆盖范围。
在本实施例中，从用户设备获取的TAC的指示信息是预配置于用户设备上的，而从基站设备接收的TAC的指示信息是在用户设备从基站设备接收TAC时从基站设备接收的。因此，从基站设备接收的指示信息可能是更准确的、更新后的指示信息，基于从基站设备接收的指示信息，可以更准确地确定TAC的适用范围，进而用户设备能够准确地确定自己所对应的TAC，有助于网络确定用户设备更精确的位置。
