具体实施方式
本申请的实施方式部分使用的术语仅用于对本申请的具体实施例进行解释，而非旨在限定本申请。
本申请实施例可应用于各种类型的通信系统。图1为本申请实施例提供的一种应用场景示意图。如图1所示的通信系统，主要包括网络设备11和终端12。
其中，1)网络设备11可以是网络侧设备，例如，无线保真(Wireless-Fidelity，WIFI)的接入点AP、下一代通信的基站，如5G的gNB或小站、微站，TRP，还可以是中继站、接入点、车载设备、可穿戴设备等。在本实施例中，不同通信制式的通信系统中的基站不同。为了区别起见，将4G通信系统的基站称为LTE eNB，5G通信系统的基站称为NR gNB，既支持4G通信系统又支持5G通信系统的基站称为eLTE eNB,这些名称仅为了方便区别，并不具有限制意义。
2)终端12又称之为用户设备(User Equipment，UE)，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。常见的终端例如包括：手机、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，例如智能手表、智能手环、计步器等。
3)“多个”是指两个或两个以上，其它量词与之类似。“和/或”，描述关联对象的对应关系，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。字符“/”一般表示前后关联对象是一种“或”的关系。
需要说明的是，图1所示的通信系统中所包含的终端12的数量和类型仅仅是一种距离，本申请实施例病不限制于此。例如，还可以包括更多的与网络设备11进行通信的终端12，为简明描述，不在附图中一一描述。此外，在如图1所示的通信系统中，尽管示出了网络设备11和终端12，但是该通信系统可以并不限于包括网络设备11和终端12，例如还可以包括核心网节点或用于承载虚拟化网络功能的设备等，这些对于本领域技术人员而言是显而易见的，在此不一一赘述。
另外，本申请实施例不仅可应用于下一代无线通信系统,即5G通信系统，还可应用于未来可能出现的其他系统,例如下一代的wifi网络、5G车联网等。
通常情况下，当终端处于空闲态(idle state)时，该终端与网络设备之间的无线资源控制(Radio Resource Control，RRC)连接断开，该终端与该网络设备无连续数据传输。与空闲态类似，当终端处于去活动态(inactive state)时，该终端也会与网络设备断开RRC连接，无连续数据传输。去活动态是一种无线资源控制(Radio Resource Control，RRC)状态，也称为RRC去活动态。去活动态不同于空闲态的是：当终端处于去活动态时，该终端和接入网设备会保存该终端的上下文，且接入网设备会向该终端发送无线接入网通知区(RAN Notification Area，RNA)信息。通常将配置终端进入去活动态并且存储该终端上下文的接入网设备为源网络设备，或anchor(锚点)网络设备。
当终端从源网络设备接收无线接入网通知区(RAN Notification Area，RNA)信息并进入去活动态后，该终端可以长时间处于该RNA区域内，也可能会移动出该RNA区域。通常情况下，当该终端进行了小区重选，重选到该RNA区域内的其它小区时，该终端也不会因为服务小区的变化向该源网络设备发送无线接入网通知区更新(RNA Update，RNAU)通知消息。但是，当该终端移动出该RNA区域时，该终端会向当前所在服务小区的网络设备发送RNAU通知消息，用于通知网络该终端移出了原配置的RNA区域。从而，使得网络设备或核心网节点及时确定该终端移动出了源基站给该终端分配的RNA，当需要寻呼该终端时，可以更好的确定寻呼区域，节省信令开销。在一些场景中，该源网络设备会向进入去活动态的终端发送配置信息，该配置信息包括用于指示该终端周期性发送RNAU通知消息的信息，使得该终端在该RNA区域内移动时，可周期性的向该源网络设备发送RNAU通知消息。周期性的RNAU通知消息可以保证该源网络设备记录的该终端的状态和该终端的实际状态一致。
源网络设备向终端发送的RNA信息可包括如下几种可能的形式：
一种可能的形式是：该RNA信息为小区信息。小区信息包括至少一个小区的标识信息,该至少一个小区的标识信息构成小区列表。可选地，小区的标识信息具体可以包括：小区的小区全局标识(Cell Global Identifier，CGI)、物理小区标识(Physical Cell Identifier，PCI)、小区标识(cell identifier)中的至少一种；
另一种可能的形式是：该RNA信息为RAN区域信息。RAN区域信息包括至少一个无线接入网 (Radio Access Network，RAN)区域(area)标识(Identity,ID),该至少一个RAN area ID构成RAN area ID列表。可选地，RAN area ID可以包括跟踪区标识(Tracking Area Identity，TAI)和RAN区域码(RAN Area Code,RANAC)，或者RAN area ID仅包括RANAC。其中RANAC标识的区域包括一个或多个小区。可选地，RANAC在TAI范围内唯一。
再一种可能的形式是：该RNA信息为跟踪区域信息。跟踪区域信息包括至少一个跟踪区标识(Tracking Area Identity，TAI),该至少一个TAI构成TAI列表。可选地，TAI可以包括PLMN标识和跟踪区码(Tracking Area Code，TAC)，或者TAI仅包括跟踪区码。
其中，RAN area ID和TAI均是小区的一种区域标识信息，不同的是：RAN area ID是接入网感知的，TAI是核心网感知的。跟踪区包括一个或多个小区，RAN area也可包括一个或多个小区。可选的，RAN area的范围小于跟踪区TA。
在本实施例中，源网络设备向终端发送的RNA信息可包括至少一个RAN area ID或至少一个TAI。以该RNA信息包括至少一个RAN area ID为例，如图2所示，跟踪区TA 20包括多个小区，例如包括小区0、小区1、小区2、小区3、小区4、小区5、小区6、小区7、小区8。其中，小区0为源基站小区即源基站对应的小区，源基站可向该终端发送RNA信息，该RNA信息包括至少一个RAN area ID，该至少一个RAN area ID可构成RAN area ID列表。如图2所示，小区1、小区2、小区3、小区4、小区5分别是源基站小区的邻小区，小区6、小区7、小区8分别是源基站小区的非邻小区。可选地，小区1、小区2、小区3、小区4、小区5对应的基站和源基站可以具有直接的接口，比如Xn接口；小区6、小区7、小区8对应的基站和源基站间没有直接的接口。其中，小区1、小区2、小区3、小区4分别对应的RAN area ID为10，小区5对应的RAN area ID为4，小区6、小区7分别对应的RAN area ID为10，小区8对应的RAN area ID为4，源基站小区对应的RAN area ID为10。源基站与邻小区基站之间有直接的Xn接口，源基站通过该Xn接口可获取到邻小区对应的RAN area ID。可选地，源基站根据邻小区对应的RAN area ID向该终端发送的RNA信息包括RAN area ID 10和RAN area ID 4，RAN area ID 10和RAN area ID 4构成RAN area ID列表。
但是，当该终端移动到如图2所示的实线区域22所示的范围内时，由于实线区域22所示范围内的小区6、小区7、小区8分别对应的RAN area ID均在源基站给该终端发送的RAN area ID列表中，该终端认为自己没有移动出源基站给该终端分配的RNA，因此，不向当前所在的服务小区中的基站发送RNAU通知消息。
例如，该终端移动到小区6内，由于小区6的RAN area ID为10，小区6的RAN area ID在源基站给该终端发送的RAN area ID列表中，同理，当该终端移动到小区8时，由于小区8的RAN area ID为4，小区8的RAN area ID在源基站给该终端发送的RAN area ID列表中，即当该终端移动到实线区域22所示的范围内时，该终端认为其没有移动出源基站给该终端分配的RNA，所以该终端不发送RNAU通知消息，当核心网节点将该终端对应的下行数据或信令发送到源基站时，将导致该源基站无法成功寻呼到该终端，导致该终端无法正常接收下行数据或信令。为了解决该问题，本申请提出了一种通信方法,以提高寻呼到该终端的成功率。下面结合具体的应用场景，对该通信方法进行介绍。
图3为本申请提供的一种通信方法示意图。如图3所示，本实施例所述的通信方法适用于如图2所示的应用场景。在图3中，第一网络设备可以是配置终端进入去活动态的源基站。第二网 络设备具体可以是与源基站有直接接口例如Xn接口的基站，如图2所示，第二网络设备具体可以是与源基站小区相邻的小区1、小区2、小区3、小区4、小区5中至少一个小区对应的基站。第三网络设备具体可以是与源基站没有直接接口的基站，如图2所示，第三网络设备具体可以是与源基站小区不相邻的小区6、小区7、小区8中至少一个小区对应的基站。该通信方法具体包括如下步骤：
步骤S301、第一网络设备向终端发送无线接入网通知区RNA信息，该RNA信息包括RAN区域标识10和RAN区域标识4。
如图2所示在本实施例中，以第一网络设备给去活动态的终端配置的RNA信息为RAN区域信息为例，在图2所示的场景中，该RAN区域信息例如可以包括RAN区域标识10和RAN区域标识4。
步骤S302、终端进入去活动态。
当终端接收到第一网络设备发送的RNA信息后，进入去活动态。
步骤S303、第一网络设备向核心网节点发送RNA信息。
在本实施例中，第一网络设备在给去活动态的终端分配RNA后，将RNA信息发送给核心网节点。可选的，第一网络设备也可以在无法寻呼到去活动态的终端时，向核心网节点发送RNA信息。
此处，以第一网络设备给去活动态的终端分配RNA后，将RNA信息发送给核心网节点为例，当该核心网节点从第一网络设备接收RNA信息后，根据该RNA信息包括的RAN区域标识10确定出该RAN区域标识10所对应的至少一个小区，根据该RNA信息包括的RAN区域标识4确定出该RAN区域标识4所对应的至少一个小区。
具体的，核心网节点可根据小区的标识信息，以及该小区所属的RAN区域的标识信息，确定RAN区域标识10和RAN区域标识4所对应的小区的网络设备。例如，该核心网节点根据如下表1所示的对应关系，确定寻呼该终端的网络设备。可以理解的是，核心网节点可以将RAN区域标识10和RAN区域标识4所对应的小区的全部网络设备都确定为寻呼该终端的网络设备，也可以是将RAN区域标识10和RAN区域标识4所对应的小区的部分网络设备确定为寻呼该终端的网络设备。一种可能的方式中，该部分网络设备，例如，可以是RAN区域标识10和RAN区域标识4所对应的小区的全部网络设备中除已寻呼该终端失败之外的网络设备。
第一网络设备可以向核心网节点发送已对终端寻呼失败的网络设备的标识信息，从而使得核心网节点获知哪些网络设备已经对终端寻呼失败，并指示该RAN区域对应的小区对应的网络设备中已寻呼该终端失败之外的网络设备寻呼该终端，避免已寻呼失败的网络设备重复寻呼该终端，可以减少不必要的寻呼开销，节省网络资源。
一种可能的方式中，可以是第一网络设备在向核心网节点发送RNA信息时，进一步给该核心网节点发送已对终端寻呼失败的网络设备的标识信息。
表1
小区的标识信息 RAN区域的标识信息
小区ID 0 RAN area ID 10
小区ID 1 RAN area ID 10
小区ID 2 RAN area ID 10
小区ID 3 RAN area ID 10
小区ID 4 RAN area ID 10
小区ID 5 RAN area ID 4
小区ID 6 RAN area ID 10
小区ID 7 RAN area ID 10
小区ID 8 RAN area ID 4
可以理解的是，表1所示的对应关系，可以是核心网节点通过从网络设备接收到的小区的标识信息和该小区对应的RAN area ID信息确定出来的，该网络设备不限于第一网络设备、第二网络设备、第三网络设备，还可以是除第一网络设备、第二网络设备、第三网络设备之外的其他网络设备。
核心网节点根据表1所示的对应关系，确定出RAN区域标识10对应的小区包括小区0、小区1、小区2、小区3、小区4、小区6、小区7，RAN区域标识4对应的小区包括小区5、小区8。其中，小区1、小区2、小区3、小区4和小区5对应的基站和源基站之间有直接的接口，本实施例中可以称为第二网络设备；小区6、小区7、小区8对应的基站和源基站之间没有直接的接口，本实施例中可以称为第三网络设备。核心网节点可指示第一网络设备、第二网络设备、第三网络设备中的全部网络设备或者部分网络设备寻呼该终端。对于指示第一网络设备、第二网络设备以及第三网络设备寻呼该终端的方式可以分别参考步骤S304-S305，S306-S307，S308-S309。
步骤S304、核心网节点向第一网络设备发送指示信息。
步骤S305、第一网络设备发送寻呼终端的寻呼消息，该寻呼消息包括终端的标识信息。
步骤S306、核心网节点向第二网络设备发送指示信息。
步骤S307、第二网络设备发送寻呼终端的寻呼消息，该寻呼消息包括终端的标识信息。
步骤S308、核心网节点向第三网络设备发送指示信息。
步骤S309、第三网络设备发送寻呼终端的寻呼消息，该寻呼消息包括终端的标识信息。
如上步骤S304-S309，核心网节点分别向第一网络设备、第二网络设备、第三网络设备发送指示信息，分别用于指示第一网络设备、第二网络设备、第三网络设备发送寻呼该终端的寻呼消息。该指示信息可以用于指示第一网络设备、第二网络设备、第三网络设备发送第一寻呼消息，例如RAN触发的寻呼消息(RAN based paging)；也可以用于指示第一网络设备、第二网络设备、第三网络设备发送第二寻呼消息例如核心网(Core Network,CN)触发的寻呼消息(CN based paging)。可以理解的是，该指示信息是从功能上进行描述的，该指示信息可以是显式的指示，或者是隐式的消息名称或者信元指示。
第一网络设备、第二网络设备、第三网络设备从核心网节点接收到指示信息后，按照该指示信息的指示发送相应的寻呼消息。如果该寻呼消息是RAN based paging，则RAN based paging中包括终端的第一标识信息，该第一标识信息可以在RNA内唯一识别终端。如果该寻呼消息是CN based paging，则CN based paging中包括终端的第二标识信息，该终端的第二标识信息可以是该终端对应的系统架构演进临时移动用户标识(System architecture-Temporary Mobile Subscriber Identity，S-TMSI)、国际移动用户标识(International Mobile Subscriber Identity，IMSI)、基于该S-TMSI或该IMSI确定的标识信息中的任一种。
需要说明的是，本实施例不限定步骤S304、步骤S306、步骤S308的执行顺序，也不限定步骤S305、步骤S307、步骤S309的执行顺序。可以理解的是，在核心网设备指示部分网络设备(例如第三网络设备)寻呼该终端的情况下，也可以是不执行S304-S307。
可选地，核心网节点向第一网络设备、第二网络设备、第三网络设备分别发送指示信息时，可以将该终端的第二标识信息携带在该指示信息中，第一网络设备、第二网络设备、第三网络设 备根据该指示信息分别发送用于寻呼该终端的第二寻呼消息，该第二寻呼消息包括该终端的第二标识信息。
一种可能的方式中，，本申请实施例中步骤S304-步骤S309描述的可以是第一网络设备将RNA信息发送给核心网节点，该核心网节点从其他网元接收到该终端对应的下行数据或信令后的一种可能流程。
另一种可能的方式中，本申请实施例中步骤S303-步骤S309描述的可以是第一网络设备给去活动态的终端分配RNA后，从核心网节点接收到该终端对应的下行数据或信令，并寻呼该终端失败后的一种可能流程，本申请实施例对此不做限定。
另外，本实施例以源基站向终端发送的RNA信息为RAN区域信息为例，本实施例还可以适用RNA信息为跟踪区域信息的场景，或者RNA信息为其它配置的场景。具体实现方式与图3所示实施例的实现方式类似，此处不再赘述。
本实施例通过第一网络设备向核心网节点发送该第一网络设备给去活动态的终端分配的RNA信息，该RNA信息可包括至少一个无线接入网RAN区域标识，核心网节点确定出该RAN区域标识对应的小区，并指示该对应的小区的网络设备寻呼该终端，避免去活动态的终端移动出第一网络设备给该终端配置的RNA时无法寻呼到该终端，从而使得该终端的下行信令或数据可以及时发送给该终端，提升终端的业务体验。
在上述实施例的基础上，第一网络设备还可以向核心网节点发送终端的标识信息，该终端的标识信息可以是第一标识信息，也可以是第二标识信息。其中，第一标识信息和第二标识信息具体如上述实施例所述，此处不再赘述。
以图3为例，在步骤S303中，第一网络设备可以向核心网节点发送RNA信息和该终端的第一标识信息；在步骤S304中，核心网节点向第一网络设备发送的指示信息用于指示第一网络设备发送寻呼该终端的第一寻呼消息例如RAN based paging；在步骤S305中，第一网络设备发送的寻呼消息具体为RAN based paging，该RAN based paging中包括该终端的第一标识信息；步骤S306-步骤S309与此类似，此处不再赘述。
或者，在步骤S303中，第一网络设备可以向核心网节点发送RNA信息和该终端的第二标识信息；在步骤S304中，核心网节点向第一网络设备发送的指示信息用于指示第一网络设备发送寻呼该终端的第二寻呼消息例如CN based paging；在步骤S305中，第一网络设备发送的寻呼消息具体为CN based paging，该CN based paging中包括该终端的第一标识信息；步骤S306-步骤S309与此类似，此处不再赘述。
本实施例通过第一网络设备向核心网节点发送终端的第一标识信息或第二标识信息，核心网节点可指示网络设备发送第一寻呼消息或第二寻呼消息来寻呼该终端，从而提高网络设备寻呼该终端的灵活性。
另外，在上述实施例的基础上，第一网络设备还可以向核心网节点发送该终端监听第一寻呼消息的周期或该第一寻呼消息的发送周期。
以图3为例，在步骤S303中，第一网络设备可以向核心网节点发送RNA信息、该终端的第一标识信息和该寻呼配置信息。在步骤S306和步骤S308中，核心网节点向第二网络设备、第三网络设备发送的指示信息具体为第一指示信息，且该第一指示信息中包括该终端的第一标识信息和该寻呼配置信息，在步骤S307和步骤S309中，第二网络设备、第三网络设备可根据该寻呼配置信息，在终端监听第一寻呼消息的周期内向该终端发送第一寻呼消息，以使得该终端可正常接收 到该第一寻呼消息，提高寻呼到该终端的成功率。
在图3基础上，核心网节点指示第一网络设备、第二网络设备、第三网络设备中的全部或者部分网络设备寻呼该终端后，且所指示的网络设备均寻呼该终端失败该核心网节点还可以向该核心网节点给该终端分配的跟踪区内的网络设备发送第二指示信息，该第二指示信息用于指示该核心网节点给所述终端分配的跟踪区内的网络设备发送用于寻呼该终端的第二寻呼消息。由于核心网节点给该终端分配的跟踪区比源基站给该终端分配的RNA大，因此，该核心网节点指示该跟踪区TA内的基站寻呼该终端时，可在更大范围内寻呼该终端，从而可以进一步提高寻呼到该终端的成功率。
可以理解的是，上述实施例中的部分或全部步骤骤或操作仅是示例，本申请实施例还可以执行其它操作或者各种操作的变形。此外，各个步骤可以按照上述实施例呈现的不同的顺序来执行，并且有可能并非要执行上述实施例中的全部操作。
作为另一种可能的实施例，下面介绍该核心网节点建立小区标识与该小区所属的RAN区域标识之间对应关系的方法，该方法包括如下几种可行的实现方式：
一种可行的实现方式是：如图4所示，基站向核心网节点发送RAN区域标识和小区的标识信息。该RAN区域标识是该基站对应的小区所属的RAN区域的标识。该核心网节点根据该基站对应的小区，建立该小区标识与该RAN区域标识的对应关系。
可选地，该基站对应一个小区，基站向核心网节点发送该小区对应的RAN区域标识。
可选地，该基站对应多个小区，该多个小区中每个小区所属的RAN区域的标识相同，即多个小区对应的RAN area ID相同，基站向核心网节点发送该多个小区对应的RAN area ID。该核心网节点建立该多个小区中每个小区的标识与该RAN area ID的对应关系。
另一种可行的实现方式是：如图4所示，基站向核心网节点发送小区的标识信息和该小区所属的RAN区域的标识信息。
可选地，该基站可以对应多个小区，该多个小区中每个小区所属的RAN区域的标识不同，即多个小区对应的RAN area ID不同，例如，该基站对应小区1和小区2，小区1对应的RAN area ID为1，小区2对应的RAN area ID为2，基站向核心网节点发送小区1的标识信息与RAN area ID1，以及小区2的标识信息与RAN area ID 2。可以理解的是，该基站对应的多个小区所属的RAN区域也可以相同，本申请实施例对此不做限定。
可选的，也可以是该基站对应1个小区1，该小区可以属于不同的RAN区域，即该小区对应多个不同的RAN area ID，例如，该小区对应RAN area ID 1和RAN area ID 2，基站向核心网节点发送该小区的标识信息1、RAN area ID 1和RAN area ID 2。或者，基站向核心网节点发送该小区的标识信息1和RAN area ID 1，以及该小区的标识信息1和RAN area ID 2。
可以理解的是，本实施例中的基站可以是上述实施例中的第一网络设备，也可以是第二网络设备、第三网络设备，另外，还可以是其他网络设备，本实施例并不做具体限定。
需要说明的是，本实施例以源基站向终端发送的RNA信息为RAN区域信息为例，本实施例还可以适用RNA信息为跟踪区域信息的场景，或者RNA信息为其它配置的场景。
可选的，基站可以在给核心网节点发送的接口建立请求消息或基站配置更新消息中携带以下任意一种：RAN区域标识，小区的标识信息和该小区所属的RAN区域的标识信息，跟踪区标识，小区的标识信息和该小区所述的跟踪区的标识信息。
可以理解的是，上述实施例中核心网节点建立小区标识与该小区所属的RAN区域标识之间对应关系的方法，可以适用于如图3所示的方法实施例，也可以独立于图3所述的方法实施例，适用于其他可以应用该对应关系的场景，本申请实施例对此不做限定。
图5为本申请提供的又一种通信方法示意图。如图5所示，该通信方法可以包括如下步骤：
步骤S501、源基站向终端发送RNA信息和至少一个小区的标识信息。
本实施例以源基站向终端发送的RNA信息为RAN区域信息为例，该RAN区域信息包括RAN区域标识10和RAN区域标识4，另外，源基站还向终端发送至少一个小区的标识信息，该至少一个小区中每个小区所属的无线接入网区域的标识信息属于该RNA信息包括的至少一个无线接入网区域的标识信息。可选地，该至少一个小区中每个小区的PLMN标识属于该RNA内至少一个小区的PLMN标识。例如，源基站向终端发送的至少一个小区的标识信息是如图2所示的小区1、小区2、小区3、小区4、小区5的标识信息。小区1、小区2、小区3、小区4对应的RAN area ID分别为10，RAN area ID 10属于源基站给该终端发送的RNA信息包括的RAN区域标识10和RAN区域标识4。小区5对应的RAN area ID 4也属于源基站给该终端发送的RNA信息包括的RAN区域标识10和RAN区域标识4。可选地，在本实施例中，将该小区1、小区2、小区3、小区4、小区5的标识信息构成的列表称为白名单。一种可能的方式中，该白名单中的小区可以是源基站对应小区的相邻小区。或者，另一种可能的方式中，该白名单中的小区对应的基站与源基站有直接的接口，例如Xn接口。
或者，源基站向终端发送的至少一个小区的标识信息是如图2所示的小区6、小区7、小区8的标识信息。小区6、小区7对应的RAN area ID分别为10，RAN area ID 10属于源基站给该终端发送的RNA信息包括的RAN区域标识10和RAN区域标识4。小区8对应的RAN area ID 4也属于源基站给该终端发送的RNA信息包括的RAN区域标识10和RAN区域标识4。可选地，在本实施例中，将该小区6、小区7、小区8的标识信息构成的列表称为黑名单。一种可能的方式中，该黑名单中的小区是源基站对应小区的非相邻小区。或者，另一种可能的方式中，该黑名单中的小区对应的基站与源基站没有直接的接口，例如Xn接口。
在本实施例中，小区的标识信息可以是小区全局标识(Cell Global Identifier，CGI)，该CGI用于唯一标识小区。或者，小区的标识信息可以是小区标识，用于在一个PLMN内唯一识别小区。或者，小区的标识信息可以是物理小区标识(Physical Cel l Identifier，PCI)和频点。如果采用小区标识，或者采用PCI和频点来标识小区，可结合该小区对应的RAN area ID来唯一标识该小区，即通过PCI、频点和RAN area ID来唯一标识该小区。
步骤S502、终端进入去活动态。
该终端从源基站接收到RNA信息，以及至少一个小区的标识信息后，进入去活动态。
步骤S503、终端根据终端当前小区的标识信息和该至少一个小区的标识信息确定是否发送RNAU通知消息。
去活动态的终端可以在RAN area ID 10和RAN area ID 4对应的小区内移动，也可以移动出RAN area ID 10和RAN area ID 4对应的小区，
本申请实施例中，对于终端当前小区所属的无线接入网区域的标识信息属于源基站给该终端发送的RNA信息包括的至少一个无线接入网区域的标识信息的场景，例如，该终端当前小区所属的无线接入网区域的标识信息为RAN area ID 10，RAN area ID 10属于源基站向该终端发送的RNA信息中的至少一个无线接入网区域的标识信息。或者，该终端当前小区所属的无线接入网区 域的标识信息为RAN area ID 10，与源基站配置给该终端的RNA信息中的RAN area ID 10相同。如图2所示，该当前小区可能是小区1、小区2、小区3、小区4、小区6、小区7中的一个。若该终端当前小区所属的无线接入网区域的标识信息为RAN area ID 4，则当前小区可能是小区5、小区8中的一个。
终端根据该终端当前小区的标识信息和该至少一个小区的标识信息确定是否发送RNAU通知消息，包括如下几种可能的情况：
一种可能的情况是：该至少一个小区用于指示终端驻留到该至少一个小区的标识信息对应的小区中的任一小区，向当前驻留的小区的基站发送RNAU通知消息，例如，一种可能的方式中，该至少一个小区是源基站对应小区的非邻小区。例如，源基站向终端发送的至少一个小区的标识信息是小区6、小区7、小区8的标识信息。可选地，小区6、小区7、小区8是源基站对应小区的非邻小区。或者，可以理解的是，此时源基站向终端发送的是黑名单。在这种情况下，若该终端当前驻留的小区的标识信息与该黑名单中一个小区的标识信息相同，则该终端向当前驻留的小区的基站发送RNAU通知消息。
例如，该终端驻留到小区6，小区6对应的RAN area ID为10，RAN area ID为10属于源基站向该终端发送的RNA信息中的至少一个无线接入网区域的标识信息；或者，小区6对应的RAN area ID 10，与源基站配置给该终端的RNA信息中的RAN area ID 10相同。此时终端接收到的至少一个小区的标识信息是小区6、小区7、小区8，即小区6的标识信息在黑名单里，则该终端向小区6对应的基站发送RNAU通知消息，以便网络设备或核心网节点确定该终端的位置信息。
一种可能的情况是：该至少一个小区的标识信息用于指示终端驻留到该至少一个小区的标识信息对应的小区外的任一小区，向当前驻留的小区的基站发送RNAU通知消息，例如，一种可能的是方式中，该至少一个小区可以是是源基站对应小区的邻小区。例如，源基站向终端发送的至少一个小区的标识信息是小区1、小区2、小区3、小区4、小区5的标识信息。可选地，小区1、小区2、小区3、小区4、小区5是源基站对应小区的邻小区。或者，可以理解的是，此时源基站向终端发送的是白名单。在这种情况下，若该终端当前驻留的小区的标识信息与该白名单中每个小区的标识信息均不相同，则该终端向当前驻留的小区的基站发送RNAU通知消息。
例如，该终端驻留到小区6，小区6对应的RAN area ID为10，RAN area ID为10属于源基站向该终端发送的RNA信息中的至少一个无线接入网区域的标识信息；或者，小区6对应的RAN area ID 10，与源基站配置给该终端的RNA信息中的RAN area ID 10相同。此时终端接收到的至少一个小区的标识信息是小区1、小区2、小区3、小区4、小区5，即小区6的标识信息不在白名单里，则该终端向小区6对应的基站发送RNAU通知消息，以便网络设备或核心网节点确定该终端的位置信息。
可以理解的是，对于该终端当前小区所属的无线接入网区域的标识信息不属于源基站给该终端发送的RNA信息包括的至少一个无线接入网区域的标识信息的场景，终端向当前小区的网络设备发送RNAU通知消息。
一种可能的方式中，可通过通信协议预先约定源基站给终端发送的至少一个小区的标识信息是白名单还是黑名单。
另外，作为另一种可实现的方式，源基站还可以向终端发送一个指示信息，该指示信息用于指示源基站给终端发送的至少一个小区的标识信息是白名单或黑名单。源基站可以将该指示信息和该至少一个小区的标识信息同时发送给终端，也可以先后发送给终端。
可以理解的，本实施例以源基站向终端发送的RNA信息为RAN区域信息为例，本实施例还可以适用RNA信息为跟踪区域信息的场景，或者RNA信息为其它配置的场景。具体实现方式与图5所示实施例的实现方式类似，此处不再赘述。
本实施例通过源基站向终端发送RNA信息和至少一个小区的标识信息，该至少一个小区的标识信息可以构成白名单或黑名单，当该终端进入黑名单内的小区，或离开白名单内的小区时，终端向当前小区中的基站发送RNAU通知消息，以便网络设备或核心网节点确定终端的位置信息，从而当下行数据或信令到达时，使得网络设备或核心网节点可以寻呼到该终端。
为了将上述实施例中源基站向终端发送的RNA信息包括的至少一个无线接入网区域的标识信息和后续实施例中涉及到的核心网节点向源基站发送的至少一个无线接入网区域的标识信息加以区分。将上述实施例中源基站向终端发送的RNA信息包括的至少一个无线接入网区域的标识信息称为至少一个第一无线接入网区域的标识信息，将后续实施例中涉及到的核心网节点向源基站发送的至少一个无线接入网区域的标识信息称为至少一个第二无线接入网区域的标识信息。同理，将上述实施例中源基站向终端发送的RNA信息包括的至少一个跟踪区的标识信息称为至少一个第一跟踪区的标识信息，将后续实施例中涉及到的核心网节点向源基站发送的至少一个跟踪区的标识信息称为至少一个第二跟踪区的标识信息。
作为一种可能的实施例，源基站可通过如下几种可行的实现方式确定给该终端发送的至少一个小区的标识信息。
一种可行的实现方式：源基站从核心网节点接收至少一个第二无线接入网区域的标识信息和该至少一个第二无线接入网区域中每个第二无线接入网区域的标识信息对应的小区的标识信息，并根据该至少一个第二无线接入网区域的标识信息和该至少一个第二无线接入网区域中每个第二无线接入网区域的标识信息对应的小区的标识信息确定至少一个小区的标识信息。
可选的，核心网节点还可以向源基站发送每个第二无线接入网区域对应的小区的基站的标识信息。根据该基站的标识信息，源基站可以确定其和该基站间是否有直接的接口。该直接的接口可以是原来的接口，也可以是源基站根据该基站的标识信息新建立的接口。
在本实施例中，第二无线接入网区域的标识信息和第一无线接入网区域的标识信息相同，也可以不同。例如，核心网节点按照如图4所示的方式接收基站对应的小区标识，以及该小区所属的RAN区域的标识信息，该基站可以是小区0、小区1、小区2、小区3、小区4、小区5对应的基站，也可以是小区6、小区7、小区8对应的基站。核心网节点根据小区0、小区1、小区2、小区3、小区4、小区6、小区7分别对应的小区标识，以及小区0、小区1、小区2、小区3、小区4、小区6、小区7分别对应的RAN area ID，可确定出RAN area ID 10和RAN area ID 10对应的小区的标识信息。同理，核心网节点可确定出RAN area ID 4和RAN area ID 4对应的小区的标识信息。另外，如图4所示，该基站还可以是其他小区的基站，其他小区对应的RAN area ID例如为3，该核心网节点还可确定出RAN area ID 3和RAN area ID 3对应的小区的标识信息。
例如，核心网节点将RAN area ID 10和对应的小区的标识信息，以及RAN area ID 4和对应的小区的标识信息发送给源基站。比如，核心网节点将{RAN area ID 10；小区1、小区2、小区3、小区4、小区6、小区7}和{RAN area ID 4；小区5、小区8}发送给源基站。源基站根据RAN area ID 10和对应的小区的标识信息，以及RAN area ID 4和对应的小区的标识信息，确定出源基站和小区6、小区7、小区8对应的基站之间没有直接的接口，则源基站可以将小区6、小区7、小 区8作为黑名单。或者，源基站将小区0、小区1、小区2、小区3、小区4和小区5作为白名单。
可选地，核心网节点还可以发送上述小区对应的基站的标识信息给源基站。作为一种实现方式，假设每个基站下只有一个小区，且基站的标识信息和小区的标识信息是对应的，以源基站的标识信息为0，源基站下的小区0的标识信息为0。则核心网节点将{RAN area ID 10；(基站1，小区1)、(基站2，小区2)、(基站3，小区3)、(基站4，小区4)、(基站6，小区6)、(基站7，小区7)}和{RAN area ID 4；(基站5，小区5)、(基站8，小区8)}发送给源基站。源基站根据从核心网接收到的RAN area ID、小区的标识信息和基站的标识信息，确定出源基站和基站6、基站7和基站8之间没有直接的接口，则源基站可以将小区6、小区7、小区8作为黑名单。或者，源基站将小区0、小区1、小区2、小区3、小区4和小区5作为白名单。
可选地的，核心网节点向源基站发送RAN area ID和该RAN area ID对应的小区的标识信息之前，可以接收基站发送的RAN area ID信息。基于基站的请求，核心网节点选择性的发送对应的RAN area ID和该RAN area ID对应的小区的标记信息，可以减少基站和核心网间的信令开销。比如本实施例中，若源基站向核心网节点发送RAN area ID 10。核心网节点只向基站发送RAN area ID 10以及RAN area ID 10对应的小区的标识信息给源基站。
可选的，核心网节点给源基站发送的至少一个第二无线接入网区域的标识信息和该至少一个第二无线接入网区域中每个第二无线接入网区域的标识信息对应的小区的标识信息，可以包括在初始上下文建立请求(INITIAL CONTEXT SETUP REQUEST)、终端上下文修改请求(UE CONTEXT MODIFICATION REQUEST)、路径切换请求响应(PATH SWITCH REQUEST ACKNOWLEDGE)中的至少一种信令中，另外，并不限于上述信令。
可以理解的是，本实施例以源基站从核心网节点接收至少一个第二无线接入网区域的标识信息和该至少一个第二无线接入网区域中每个第二无线接入网区域的标识信息对应的小区的标识信息为例。另外，本实施例还可以适用于源基站从核心网节点接收至少一个第二跟踪区的标识信息和该至少一个第二跟踪区中每个第二跟踪区对应的小区的标识信息，并根据该至少一个第二跟踪区的标识信息和该至少一个第二跟踪区中每个第二跟踪区对应的小区的标识信息确定至少一个小区的标识信息的场景，具体实现方式与本实施例的实现方式类似，此处不再赘述。
另一种可行的实现方式：源基站从第二网络设备接收该第二网络设备对应的小区的标识信息和小区所属的无线接入网区域或跟踪区的标识信息。可选的，源基站还可以从第二网络设备接收第二网络设备的标识信息；和/或，源基站从第二网络设备接收第三网络设备对应的小区的标识信息和小区所属的无线接入网区域或跟踪区的标识信息，可选的，还可以接收第三网络设备的标识信息。其中，第三网络设备的标识信息以及该第三网络设备对应的小区所属的无线接入网区域或跟踪区的标识信息可以是第二网络设备直接从第三设备接收的，也可以是间接通过其他网络设备获得的，本申请实施例对此不做限定。
如图6所示，源基站1和第二网络设备例如基站2之间有直接的Xn接口，源基站1和第三网络设备例如基站3之间没有直接的Xn接口，基站2和基站3之间有直接的Xn接口。源基站1和基站2可通过该Xn接口交互各自对应小区所属的RAN area或TA的标识信息。例如，源基站1可以将其对应的小区所属的RAN area或TA的标识信息通过该Xn接口发送给基站2，基站2可以将其对应的小区所属的RAN area或TA的标识信息通过该Xn接口发送给源基站1。基站2和基站3可通过Xn接口交互各自对应小区所属的RAN area或TA的标识信息。进一步地，基站2还可以将基站3对应的小区所属的RAN area或TA的标识信息发送给源基站1。或者，基站2还可以将基 站1对应的小区所属的RAN area或TA的标识信息发送给基站3。例如，源基站1对应的小区1所属的RAN area标识信息为RAN area ID 10，源基站1确认基站2对应的小区2所属的RAN area标识信息为RAN area ID 10，基站3对应的小区3所属的RAN area标识信息为RAN area ID 10。可选地，基于基站3的标识信息，源基站1确定与基站3之间没有直接的Xn接口。当源基站1向终端发送的RNA信息包括RAN area ID 10时，可将基站3对应的小区3的标识信息作为黑名单，或者将基站2对应的小区2的标识信息作为白名单。
可以理解的，本实施例以源基站向终端发送的RNA信息为RAN区域信息为例，本实施例还可以适用RNA信息为跟踪区域信息的场景，或者RNA信息为其它配置的场景。具体实现方式与图6所示实施例的实现方式一致，此处不再赘述。
可以理解的是，本申请实施例中，一个基站(基站A)向另一基站(基站B)发送RAN area标识或者TA标识信息的过程中，该基站A也会向该基站B发送该基站A的标识信息。例如，以图5所示，基站2不仅可以将其对应的小区所属的RAN area或TA的标识信息通过该Xn接口发送给源基站1，也可以将基站2的标识信息发送给源基站1。
本实施例通过源基站向终端发送RNA信息和至少一个小区的标识信息，根据终端的当前位置，及时发送RNAU通知消息及时通知网络设备或核心网节点，从而当行数据或信令到达时，使得网络设备或核心网节点可以找到终端。
可以理解的是，上述实施例中的部分或全部步骤骤或操作仅是示例，本申请实施例还可以执行其它操作或者各种操作的变形。此外，各个步骤可以按照上述实施例呈现的不同的顺序来执行，并且有可能并非要执行上述实施例中的全部操作。
可以理解的是，以上各个实施例中，由终端实现的操作或者步骤，也可以由可用于终端的部件(例如芯片或者电路)实现，由核心网节点实现的操作或者步骤，也可以由可用于核心网节点的部件(例如芯片或者电路)实现，由网络设备(例如第一网络设备、第二网络设备、第三网络设备)实现的的操作或者步骤，也可以由可用于网络设备的部件(例如芯片或者电路)实现。
