技术领域Technical field

本申请涉及无线通信技术领域，特别涉及一种进行寻呼的方法、设备及对应关系更新的方法、设备。The present application relates to the field of wireless communication technology, and in particular, to a paging method and device, and a method and device for updating correspondence.

背景技术Background technique

目前第三代移动通信标准化组织(3rd Generation Partnership Project，3GPP)正在研究5G***中支持卫星接入，以保证陆地移动网络覆盖的盲区。At present, the 3rd Generation Mobile Communications Standardization Organization (3rd Generation Partnership Project, 3GPP) is studying the support of satellite access in 5G systems to ensure the coverage of land mobile networks.

现有技术中，卫星接入技术是通过在卫星上搭载新空口(New Radio，NR)基站的方式实现，即卫星接入的无线覆盖和陆地接入的无线覆盖都是NR类型。因此，按照现有技术当5G核心网触发寻呼过程时，移动管理功能(Access And Mobility Management Function，AMF)实体需要向用户设备(User Equipment，UE)的注册区域的跟踪区(Tracking Area，TA)区域内的基站发送寻呼请求，对于地面基站来讲，由于地面基站的位置是不会发生变化的，因此被地面基站所覆盖的TA区域是不会改变的，因此地面基站可以将寻呼信息顺利的发送出去，但是卫星基站是动态变化的，卫星基站所覆盖的TA区域会根据卫星的移动改变，若继续按照地面基站的处理方式，由于TA区域对应的基站发生变化，但是仍按照TA区域之前的卫星基站进行寻呼，造成寻呼失败，且浪费资源。In the prior art, the satellite access technology is implemented by mounting a new radio (NR) base station on the satellite, that is, the wireless coverage of satellite access and the wireless coverage of land access are both NR types. Therefore, according to the prior art, when the 5G core network triggers the paging process, the mobility management function (Access And And Mobility Management Function, AMF) entity needs to register the tracking area (Tracking Area, TA) of the user equipment (User Equipment, UE) registration area ) The base station in the area sends a paging request. For the ground base station, the location of the ground base station will not change, so the TA area covered by the ground base station will not change, so the ground base station can page The information is sent out smoothly, but the satellite base station is dynamically changing. The TA area covered by the satellite base station will change according to the movement of the satellite. If you continue to follow the processing method of the ground base station, the base station corresponding to the TA area changes, but still according to the TA The satellite base station before the area performs paging, which causes paging failure and wastes resources.

综上，现有技术中在通过非同步卫星基站进行寻呼时，寻呼失败率高，浪费资源。In summary, in the prior art, when paging through an asynchronous satellite base station, the paging failure rate is high and resources are wasted.

Those of ordinary skill in the art may know that with the new network service scenarios The emergence of the technical solutions provided by the embodiments of the present application is also applicable to similar technical problems.

在寻呼过程中，寻呼设备需要向终端的注册区域的跟踪区域中的网络侧设备发送寻呼请求，以使所述网络侧设备在接收到寻呼请求后进行寻呼。During the paging process, the paging device needs to send a paging request to the network side device in the tracking area of the terminal's registration area, so that the network side device performs paging after receiving the paging request.

目前3GPP研究的在5G***中支持卫星接入，保证陆地移动网络覆盖的盲区，但是现有技术中采用卫星接入是通过在卫星上大件NR基站的方式实现，即卫星接入的无线覆盖和陆地接入的无线覆盖都是NR类型。因此，按照现有技术当5G核心网触发寻呼过程时，AMF实体需要向UE的注册区域的TA区域内的基站发送寻呼请求，但是对于非同步卫星来讲，TA区域内的卫星是动态变化的，无法准确的进行寻呼，浪费资源。At present, 3GPP is studying the support of satellite access in 5G systems to ensure the coverage of land mobile networks. However, in the existing technology, satellite access is implemented by using large NR base stations on the satellite, that is, wireless coverage of satellite access. And the wireless coverage of land access is NR type. Therefore, according to the prior art, when the 5G core network triggers the paging process, the AMF entity needs to send a paging request to the base station in the TA area of the UE's registration area, but for non-synchronous satellites, the satellites in the TA area are dynamic Changes, can not be accurately paging, wasting resources.

本申请针对上述场景，在进行寻呼时，寻呼设备通过根据卫星基站和当前覆盖区域中的跟踪区域对应的关系确定，所述终端当前所在的跟踪区域对应的卫星基站，并通过所述终端当前所在的跟踪区域对应的卫星基站进行寻呼，此时的卫星基站比不是设定好的卫星基站，而是服务与所述终端当前所在区域的卫星基站，因此终端在通过基站进行寻呼时，卫星基站可以准确的进行寻呼，减少资源的浪费。The present application is directed to the above scenario. When paging, the paging device determines, according to the correspondence between the satellite base station and the tracking area in the current coverage area, the satellite base station corresponding to the tracking area where the terminal is currently located, and passes The satellite base station corresponding to the current tracking area is used for paging. At this time, the satellite base station is not a set satellite base station, but a satellite base station serving the area where the terminal is currently located. Therefore, when the terminal performs paging through the base station The satellite base station can accurately perform paging and reduce the waste of resources.

为了使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请作进一步地详细描述，显然，所描述的实施例仅仅是本申请一部份实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其它实施例，都属于本申请保护的范围。In order to make the purpose, technical solutions and advantages of the present application more clear, the present application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments . Based on the embodiments in this application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of this application.

如图1所示，为本申请实施例提供的一种进行寻呼的方法流程图，具体包括如下步骤；As shown in FIG. 1, it is a flowchart of a paging method provided by an embodiment of the present application, specifically including the following steps;

步骤100，寻呼设备确定需要为终端进行寻呼； Step 100, the paging device determines that the terminal needs to be paged;

步骤110，所述寻呼设备通过所述终端当前所在的跟踪区域对应的卫星基站进行寻呼，其中所述当前所在的跟踪区域对应的卫星基站是根据卫星基站和当前覆盖区域中的跟踪区域的对应关系确定的。 Step 110, the paging device performs paging through the satellite base station corresponding to the tracking area where the terminal is currently located, wherein the satellite base station corresponding to the current tracking area is based on the satellite base station and the tracking area in the current coverage area Correspondence is determined.

在本申请实施例中，寻呼设备确定要为终端进行寻呼后，通过所述终端当前所在的跟踪区域对应的卫星基站进行寻呼，其中所述当前所在的跟踪区域对应的卫星基站是根据卫星基站和当前覆盖区域中的跟踪区域的对应关系确定的；由于本申请中用于进行寻呼的卫星基站是终端当前所在跟踪区域对应的卫星基站，且所述卫星基站当前的覆盖区域(即卫星基站的服务区域)中存在所述跟踪区域，并不存卫星基站的位置发生变化后，所述跟踪区域对应的卫星基站的覆盖区域中没有所述跟踪区域的情况，因此终端在通过基站进行寻呼时，卫星基站可以准确的进行寻呼，减少资源的浪费。In the embodiment of the present application, after the paging device determines to page for the terminal, the paging device performs paging through the satellite base station corresponding to the tracking area where the terminal is currently located, wherein the satellite base station corresponding to the tracking area where the terminal is currently located is based on The correspondence between the satellite base station and the tracking area in the current coverage area is determined; as the satellite base station used for paging in this application is the satellite base station corresponding to the tracking area where the terminal is currently located, and the current coverage area of the satellite base station (ie The tracking area exists in the service area of the satellite base station. There is no storage of the tracking area in the coverage area of the satellite base station corresponding to the tracking area after the position of the satellite base station changes. Therefore, the terminal performs During paging, the satellite base station can perform paging accurately, reducing waste of resources.

寻呼设备在确定终端需要进行寻呼后，根据获取到的终端的UE注册区域所包含的跟踪区域，确定当前覆盖该跟踪区域的卫星基站，由于不同的寻呼设备在确定终端需要进行寻呼后，确定卫星基站的方式不同，可以将寻呼设备分为AMF实体和地面基站。After determining that the terminal needs to be paged, the paging device determines the satellite base station currently covering the tracking area according to the tracking area included in the acquired UE registration area of the terminal, because different paging devices determine that the terminal needs to page After that, the method of determining the satellite base station is different, and the paging device can be divided into an AMF entity and a ground base station.

实施例一：寻呼设备为AMF实体。Embodiment 1: The paging device is an AMF entity.

具体的，寻呼设备为AMF实体时，当AMF实体在接收到5G核心网触发的针对空闲态UE的下行信令时，AMF实体确定需要发起寻呼。Specifically, when the paging device is an AMF entity, when the AMF entity receives downlink signaling triggered by the 5G core network for the idle UE, the AMF entity determines that paging needs to be initiated.

AMF实体在确定需要发起寻呼后，发送寻呼请求之前，AMF实体从用户设备上下文(User Equipment context，UE context)中确定当前UE的注册区域。After the AMF entity determines that it needs to initiate paging, before sending the paging request, the AMF entity determines the current UE registration area from the user equipment context (User Equipment context, UE context).

其中，所述UE的注册区域是终端在通过非同步卫星接入网络时，AMF实体为UE分配的注册区域，并将分配的UE的注册区域存储在UE context中。Wherein, the registration area of the UE is a registration area allocated by the AMF entity to the UE when the terminal accesses the network through an asynchronous satellite, and the allocated registration area of the UE is stored in the context of the UE.

由于UE的注册区域中包含有跟踪区域，因此AMF实体在确定UE的注册区域后，可以直接确定跟踪区域即终端当前所在的跟踪区域；进而根据所述终端当前所在的跟踪区域确定卫星基站。Since the registration area of the UE includes a tracking area, after determining the registration area of the UE, the AMF entity can directly determine the tracking area, that is, the tracking area where the terminal is currently located; and then determine the satellite base station according to the tracking area where the terminal is currently located.

可选的，所述寻呼设备通过下列方式确定所述终端当前所在的跟踪区域对应的卫星基站：Optionally, the paging device determines the satellite base station corresponding to the tracking area where the terminal is currently located in the following manner:

具体的，当AMF实体接收到针对UE的下行信令后，AMF实体确定UE的注册区域，其中UE的注册区域中包含有跟踪区域，在确定所述终端当前所在的跟踪区域后，将所述终端当前所在的跟踪区域的区域标识发送给卫星信息管理实体，由于卫星信息管理实体中存储有卫星基站和跟踪区域的对应关系，所述卫星信息管理实体中存储的对应关系为卫星基站和当前覆盖区域中的跟踪区域的对应关系。Specifically, after the AMF entity receives the downlink signaling for the UE, the AMF entity determines the registration area of the UE, where the registration area of the UE includes a tracking area, and after determining the tracking area where the terminal is currently located, the The area identifier of the tracking area where the terminal is currently sent to the satellite information management entity. Since the correspondence between the satellite base station and the tracking area is stored in the satellite information management entity, the correspondence between the satellite information management entity is the satellite base station and the current coverage. Correspondence between the tracking areas in the area.

因此所述卫星信息管理实体在接收到寻呼设备发送的所述终端当前所在的跟踪区域的区域标识后，根据自身存储的对应关系确定接收到的跟踪区域对应的卫星基站，并将根据对应关系确定的卫星基站通知给AMF实体；Therefore, after receiving the area identifier of the tracking area where the terminal is currently sent by the paging device, the satellite information management entity determines the satellite base station corresponding to the received tracking area according to the corresponding relationship stored by itself, and will determine the satellite base station corresponding to the received tracking area. The determined satellite base station informs the AMF entity;

相应的，所述AMF实体接收所述卫星信息管理实体通知的卫星基站，并将所述卫星信息管理实体通知的卫星基站作为所述终端当前所在的跟踪区域对应的卫星基站。Correspondingly, the AMF entity receives the satellite base station notified by the satellite information management entity, and uses the satellite base station notified by the satellite information management entity as the satellite base station corresponding to the tracking area where the terminal is currently located.

比如，AMF实体确定终端当前所在的跟踪区域为跟踪区域1，跟踪区域1的区域标识为TA1，将所述终端当前所在的跟踪区域的区域标识TA1发送给卫星信息管理实体，卫星信息管理实体根据卫星基站和当前覆盖的跟踪区域的对应关系(卫星1当前覆盖的跟踪区域为跟踪区域1、跟踪区域2、跟踪区域5、跟踪区域6；卫星2当前覆盖的跟踪区域为跟踪区域3；卫星3当前覆盖的跟踪区域为卫星4)确定跟踪区域的区域标识TA1为跟踪区域1，根据对应关系确定跟踪区域1对应的卫星基站为卫星1，将卫星1通知给AMF实体，以使AMF实体所通过卫星1进行寻呼。For example, the AMF entity determines that the tracking area where the terminal is currently located is tracking area 1, and the area identifier of the tracking area 1 is TA1, and sends the area identifier TA1 of the tracking area where the terminal is currently located to the satellite information management entity. Correspondence between the satellite base station and the currently covered tracking area (the tracking area currently covered by satellite 1 is tracking area 1, tracking area 2, tracking area 5, and tracking area 6; the tracking area currently covered by satellite 2 is tracking area 3; satellite 3 The tracking area currently covered is satellite 4) Determine the area identifier TA1 of the tracking area as tracking area 1, determine the satellite base station corresponding to tracking area 1 as satellite 1 according to the corresponding relationship, and notify satellite 1 to the AMF entity to make the AMF entity pass Satellite 1 performs paging.

在实施中，寻呼设备会将所述终端当前所在的跟踪区域的区域标识发送给卫星信息管理实体，由于卫星信息管理实体中存储有所述卫星基站和当前覆盖区域中的跟踪区域的对应关系，因此所述寻呼设备接收到的卫星基站为所述终端当前所在的跟踪区域对应的卫星基站，即所述寻呼设备获取到的卫星基站为覆盖所述终端当前所在跟踪区域的卫星基站，保证在通过获取到的卫星基站进行寻呼时，寻呼流程顺利，减少资源浪费。In implementation, the paging device will send the area identifier of the tracking area where the terminal is currently located to the satellite information management entity, because the satellite information management entity stores the correspondence between the satellite base station and the tracking area in the current coverage area Therefore, the satellite base station received by the paging device is a satellite base station corresponding to the tracking area where the terminal is currently located, that is, the satellite base station acquired by the paging device is a satellite base station covering the tracking area where the terminal is currently located, Ensure that when paging through the acquired satellite base station, the paging process is smooth and resource waste is reduced.

本申请实施例中，所述卫星信息管理实体可以根据卫星基站的卫星波束找事范围即预先规划的跟踪区域对卫星基站和当前覆盖区域中的跟踪区域的对应关系进行更新，具体的如图2所示，为本申请实施例提供的一种卫星基站和当前覆盖区域中的跟踪区域的对应关系更新的方法流程图，包括如下步骤：In the embodiment of the present application, the satellite information management entity may update the correspondence between the satellite base station and the tracking area in the current coverage area according to the satellite beam search range of the satellite base station, that is, the pre-planned tracking area, as shown in FIG. 2 The flowchart of the method for updating the correspondence between the satellite base station and the tracking area in the current coverage area provided by the embodiment of the present application includes the following steps:

步骤200，卫星信息管理实体根据接收到的卫星基站的星历信息和天线参数，确定所述卫星基站当前覆盖区域；Step 200: The satellite information management entity determines the current coverage area of the satellite base station according to the received ephemeris information and antenna parameters of the satellite base station;

步骤210，所述卫星信息管理实体根据确定的所述卫星基站当前覆盖区域及设定的跟踪区域，确定所述卫星基站当前覆盖区域中的跟踪区域；Step 210: The satellite information management entity determines the tracking area in the current coverage area of the satellite base station based on the determined current coverage area of the satellite base station and the set tracking area;

步骤220，所述卫星信息管理实体根据所述卫星基站当前覆盖区域中的跟踪区域，对所述卫星基站和当前覆盖区域中的跟踪区域的对应关系进行更新。Step 220: The satellite information management entity updates the correspondence between the satellite base station and the tracking area in the current coverage area according to the tracking area in the current coverage area of the satellite base station.

具体的，卫星基站实时获取自身的星历信息和天线参数，并将获取到的星历信息和天线参数发送给卫星信息管理实体；Specifically, the satellite base station obtains its own ephemeris information and antenna parameters in real time, and sends the obtained ephemeris information and antenna parameters to the satellite information management entity;

相应的，卫星信息管理实体接收到卫星基站上报的星历信息和天线参数后，根据上报的星历信息和天线参数推算卫星波束的照射范围，即卫星基站当前覆盖区域；Correspondingly, after receiving the ephemeris information and antenna parameters reported by the satellite base station, the satellite information management entity calculates the radiation range of the satellite beam according to the reported ephemeris information and antenna parameters, that is, the current coverage area of the satellite base station;

其中，根据卫星基站的天线参数可以确定卫星基站的覆盖区域，当卫星基站的天线参数发生变化后，卫星基站的覆盖区域发生变化；根据卫星基站的星历信息确定卫星基站位置，当卫星基站的星历信息发生变化后，卫星基站的位置发生变化。Among them, the coverage area of the satellite base station can be determined according to the antenna parameters of the satellite base station. When the antenna parameters of the satellite base station change, the coverage area of the satellite base station changes; the location of the satellite base station is determined according to the ephemeris information of the satellite base station. After the ephemeris information changes, the position of the satellite base station changes.

所述卫星信息管理实体在确定卫星基站当前覆盖区域后，根据预先规划的跟踪区域，确定卫星基站当前覆盖区域中的跟踪区域是否有变化，若所述卫星基站当前覆盖区域发生变化，则所述卫星基站当前覆盖区域中的跟踪区域发生变化，确定卫星基站当前覆盖区域中的跟踪区域，并根据确定的卫星基站当前覆盖内的跟踪区域，对卫星基站和当前覆盖区域中的跟踪区域的对应关系进行更新。After determining the current coverage area of the satellite base station, the satellite information management entity determines whether the tracking area in the current coverage area of the satellite base station changes according to the pre-planned tracking area. If the current coverage area of the satellite base station changes, then the The tracking area in the current coverage area of the satellite base station changes, determine the tracking area in the current coverage area of the satellite base station, and according to the determined tracking area in the current coverage of the satellite base station, the correspondence between the satellite base station and the tracking area in the current coverage area To update.

如图3所示，为本申请实施例中卫星基站未获取星历信息和天线参数时，卫星基站和跟踪区域相互对应的示意图；其中，图3中线条填充部分为卫星1的覆盖区域、网格填充部分为卫星2的覆盖区域、空白部分为卫星3的覆盖区域；TA表示跟踪区域的区域标识，例如跟踪区域1表示为TA1；As shown in FIG. 3, it is a schematic diagram of the satellite base station and the tracking area corresponding to each other when the satellite base station does not obtain ephemeris information and antenna parameters in the embodiment of the present application; The filled area is the coverage area of satellite 2 and the blank area is the coverage area of satellite 3; TA indicates the area identification of the tracking area, for example, tracking area 1 is indicated as TA1;

从图3中可知，卫星1的覆盖区域中的跟踪区域为跟踪区域1、跟踪区域4、跟踪区域5，确定卫星1与跟踪区域1、跟踪区域4、跟踪区域5对应；卫星2的覆盖区域中的跟踪区域为跟踪区域2、跟踪区域3、跟踪区域6，确定卫星2与跟踪区域2、跟踪区域、跟踪区域6对应。It can be seen from FIG. 3 that the tracking area in the coverage area of satellite 1 is tracking area 1, tracking area 4, and tracking area 5, and it is determined that satellite 1 corresponds to tracking area 1, tracking area 4, and tracking area 5; the coverage area of satellite 2 The tracking area in is the tracking area 2, the tracking area 3, and the tracking area 6, and it is determined that the satellite 2 corresponds to the tracking area 2, the tracking area, and the tracking area 6.

当卫星基站的天线参数和星历信息发生变化后，卫星基站当前的覆盖范围发生变化，因此覆盖范围内的跟踪区域发生变化；具体的，如图4所示，为本申请实施例在根据获取的卫星基站的星历信息和天线参数确定卫星基站当前覆盖区域后，卫星基站和当前覆盖区域中跟踪区域相互对应的示意图。其中，条填充部分为卫星1的覆盖区域、网格填充部分为卫星2的覆盖区域、空白部分为卫星3的覆盖区域；When the antenna parameters and ephemeris information of the satellite base station change, the current coverage of the satellite base station changes, so the tracking area within the coverage area changes; specifically, as shown in FIG. After the ephemeris information and antenna parameters of the satellite base station determine the current coverage area of the satellite base station, a schematic diagram of the satellite base station and the tracking area in the current coverage area corresponding to each other. Among them, the bar filled part is the coverage area of satellite 1, the grid filled part is the coverage area of satellite 2, and the blank part is the coverage area of satellite 3;

从图4中可知，卫星1的覆盖区域由边缘的3个区域变成和中间的4个区域，此时中间的4个区域为卫星1的覆盖区域，由于跟踪区域是预先规划的，即跟踪过区域的位置不会因为卫星的移动而发生改变，因此当卫星基站的位置发生变化后，卫星基站的当前覆盖区域发生变化，卫星基站当前覆盖区域中的跟踪区域发生变化；卫星1当前覆盖区域中的跟踪区域为跟踪区域1、跟踪区域2、跟踪区域、跟踪区域6，因此将卫星1与当前覆盖区域中的跟踪区域的对应关系更新为卫星1对应的跟踪区域为跟踪区域1、跟踪区域2、跟踪区域5、跟踪区域6；It can be seen from FIG. 4 that the coverage area of satellite 1 has changed from the three areas on the edge to the four areas in the middle. At this time, the four areas in the middle are the coverage areas of satellite 1. Since the tracking area is planned in advance, that is, tracking The location of the passing area will not change due to the movement of the satellite. Therefore, when the position of the satellite base station changes, the current coverage area of the satellite base station changes, and the tracking area in the current coverage area of the satellite base station changes; the current coverage area of the satellite 1 The tracking area in is tracking area 1, tracking area 2, tracking area, tracking area 6, so the correspondence between satellite 1 and the tracking area in the current coverage area is updated to the tracking area corresponding to satellite 1 is tracking area 1, tracking area 2. Tracking area 5, tracking area 6;

同理，将卫星2与当前覆盖区域中的跟踪区域的对应关系更新为卫星2对应的跟踪区域为跟踪区域3；将卫星3与当前覆盖区域中的跟踪区域的对应关系更新为卫星3对应的跟踪区域为跟踪区域4。Similarly, update the correspondence between satellite 2 and the tracking area in the current coverage area to the tracking area corresponding to satellite 2 as tracking area 3; update the correspondence between satellite 3 and the tracking area in the current coverage area to correspond to satellite 3 The tracking area is tracking area 4.

需要说明的是，所述卫星信息管理实体可以只用于更新卫星基站和覆盖区域中的跟踪区域的对应关系；还可以既用于更新卫星基站和覆盖区域内的跟踪区域的对应关系，又用于将更新后的对应关系进行存储；所述卫星信息管理实体可以部署于AMF实体内部，还可以部署于AMF实体外部，当所述卫星信息管理实体部署于AMF实体外部时，主要部署于网络存储库函数(Network Repository Function，NRF)实体内。It should be noted that the satellite information management entity can only be used to update the correspondence between the satellite base station and the tracking area in the coverage area; it can also be used to both update the correspondence between the satellite base station and the tracking area within the coverage area. To store the updated correspondence; the satellite information management entity can be deployed inside the AMF entity or outside the AMF entity. When the satellite information management entity is deployed outside the AMF entity, it is mainly deployed in network storage Library function (Network Repository Function, NRF) entity.

比如，当卫星信息管理实体部署在NRF实体内部，若卫星信息管理实体只能更新卫星基站和当前覆盖区域中的跟踪区域的对应关系时，NRF实体用于存储卫星信息管理实体更新后的卫星基站和当前覆盖区域中的跟踪区域的对应关系；或For example, when the satellite information management entity is deployed inside the NRF entity, if the satellite information management entity can only update the correspondence between the satellite base station and the tracking area in the current coverage area, the NRF entity is used to store the updated satellite base station of the satellite information management entity Correspondence with the tracking area in the current coverage area; or

若卫星信息管理实体既能更新卫星基站和当前覆盖区域中的跟踪区域的对应关系，又能存储更新后的卫星基站和当前覆盖区域中的跟踪区域的对应关系时，直接将卫星管理实体部署在NRF实体内部，NRF实体可以不具有存储所述对应关系的功能。If the satellite information management entity can not only update the correspondence between the satellite base station and the tracking area in the current coverage area, but also store the correspondence between the updated satellite base station and the tracking area in the current coverage area, the satellite management entity is directly deployed in Inside the NRF entity, the NRF entity may not have the function of storing the corresponding relationship.

在实施中，卫星基站和当前覆盖区域中的跟踪区域的对应关系可以根据卫星的星历信息和天线参数进行更新，当卫星基站的位置发生变化后，卫星基站当前覆盖区域发生变化，确定卫星基站当前覆盖区域中的跟踪区域，并根据确定的卫星基站当前覆盖区域中的跟踪区域对卫星基站和跟踪区域的对应关系进行更新，使在根据终端当前所在的跟踪区域确定对应的卫星基站进行寻呼时，可以根据最新的对应关系找到终端当前所在的跟踪区域对应的卫星基站，而不是根据固定的对应关系获取终端当前所在的跟踪区域对应的卫星基站，由于获取到的卫星基站的服务区域中包括终端当前所在的跟踪区域，因此卫星基站可以顺利的进行寻呼，降低寻呼失败率，减少资源浪费。In the implementation, the correspondence between the satellite base station and the tracking area in the current coverage area can be updated according to the satellite's ephemeris information and antenna parameters. When the position of the satellite base station changes, the current coverage area of the satellite base station changes, and the satellite base station is determined. The tracking area in the current coverage area, and the correspondence between the satellite base station and the tracking area is updated according to the determined tracking area in the current coverage area of the satellite base station, so that the corresponding satellite base station determined according to the current tracking area of the terminal is paged At this time, you can find the satellite base station corresponding to the tracking area where the terminal is currently located according to the latest correspondence, instead of acquiring the satellite base station corresponding to the tracking area where the terminal is currently located according to the fixed correspondence, because the service area of the acquired satellite base station includes The tracking area where the terminal is currently located, so the satellite base station can perform paging smoothly, reduce the paging failure rate, and reduce the waste of resources.

在实施过程中，寻呼设备根据所述终端当前所在的跟踪区域确定当前区域所在的跟踪区域对应的卫星基站后，所述寻呼设备通过所述终端当前所在的跟踪区域对应的卫星基站进行寻呼时，判断寻呼设备是否可以直接感知卫星基站；In the implementation process, after the paging device determines the satellite base station corresponding to the tracking area where the current area is located according to the tracking area where the terminal is currently located, the paging device searches through the satellite base station corresponding to the tracking area where the terminal is currently located When calling, determine whether the paging device can directly sense the satellite base station;

若寻呼设备直接感知卫星基站，则所述寻呼设备直接将寻呼请求发送给所述卫星基站，以通过所述卫星基站进行寻呼；或If the paging device directly senses the satellite base station, the paging device directly sends a paging request to the satellite base station to perform paging through the satellite base station; or

若寻呼设备不能感知卫星基站的拓扑，则所述寻呼设备将寻呼请求通过地面基站发送给所述卫星基站，以通过所述卫星基站进行寻呼。If the paging device cannot sense the topology of the satellite base station, the paging device sends a paging request to the satellite base station through the ground base station to perform paging through the satellite base station.

具体的通过下列情况进行分别介绍。The specific introduction will be made through the following situations.

情况一：寻呼设备直接将寻呼请求发送给卫星基站，以通过卫星基站进行寻呼。Case 1: The paging device directly sends the paging request to the satellite base station to perform paging through the satellite base station.

当卫星基站与AMF实体通过N2接口连接时，AMF实体可以感知卫星基站，在AMF实体确定所述终端当前所在的跟踪区域对应的卫星基站后，可以直接向获取到的卫星基站的标识信息对应的卫星基站发送寻呼请求，以通过所述卫星基站进行寻呼。When the satellite base station and the AMF entity are connected through the N2 interface, the AMF entity can sense the satellite base station, and after the AMF entity determines the satellite base station corresponding to the tracking area where the terminal is currently located, it can directly send the corresponding identification information of the obtained satellite base station to the The satellite base station sends a paging request to perform paging through the satellite base station.

以卫星信息管理实体部署在NRF实体内，且卫星信息管理实体具有更新存储对应关系的功能进行举例说明：The satellite information management entity is deployed in the NRF entity, and the satellite information management entity has the function of updating and storing the corresponding relationship.

AMF实体在接收到5G核心网触发的针对空闲态UE的下行信令时，AMF实体确定需要发起寻呼。When the AMF entity receives the downlink signaling for the idle UE triggered by the 5G core network, the AMF entity determines that paging needs to be initiated.

AMF实体在确定需要发起寻呼后，发送寻呼请求之前，AMF实体从UE context中确定当前UE的注册区域。由于UE的注册区域中包含有跟踪区域，因此AMF实体在确定UE的注册区域后，直接确定所述终端当前所处的跟踪区域；After the AMF entity determines that it needs to initiate paging, and before sending the paging request, the AMF entity determines the current UE registration area from the UE context. Since the registration area of the UE includes a tracking area, after determining the registration area of the UE, the AMF entity directly determines the tracking area where the terminal is currently located;

比如，AMF接收到针对UE1的下行信令后，确定UE1的注册区域为注册区域A，其中注册区域A中包含有跟踪区域1(TA1)；所述AMF将确定UE1当前所处的跟踪区域为跟踪区域1；For example, after receiving the downlink signaling for UE1, AMF determines that the registration area of UE1 is registration area A, where registration area A contains tracking area 1 (TA1); the AMF will determine that the tracking area where UE1 is currently located is Tracking area 1;

AMF实体将确定的所述终端当前所在的跟踪区域的区域标识发送给NRF实体，即发送给NRF实体内部的卫星信息管理实体，以使所述卫星信息管理实体根据卫星基站和当前覆盖区域中的跟踪区域的对应关系，确定所述终端当前所在的跟踪区域对应的卫星基站，并将确定的所述终端当前所在的跟踪区域对应的卫星基站通知AMF实体；The AMF entity sends the determined area identifier of the tracking area where the terminal is currently located to the NRF entity, that is, to the satellite information management entity within the NRF entity, so that the satellite information management entity is based on the satellite base station and the current coverage area. Correspondence of the tracking area, determine the satellite base station corresponding to the tracking area where the terminal is currently located, and notify the AMF entity of the determined satellite base station corresponding to the tracking area where the terminal is currently located;

基于上述内容，AMF实体将确定UE1当前所处的跟踪区域为跟踪区域1对应的区域标识TA1发送给NRF实体；以使NRF实体内部部署的卫星信息管理实体根据自身存储的“卫星1对应的跟踪区域为跟踪区域1、跟踪区域2、跟踪区域5、跟踪区域6；卫星2对应的跟踪区域为跟踪区域3；卫星3对应的跟踪区域为跟踪区域4”的对应关系，确定TA1对应的卫星基站为卫星1，并将卫星1通知AMF实体；Based on the above, the AMF entity sends the identification area TA1 that determines the current tracking area of UE1 as the tracking area 1 to the NRF entity; so that the satellite information management entity deployed inside the NRF entity can store the tracking information corresponding to “satellite 1” The tracking area is tracking area 1, tracking area 2, tracking area 5, tracking area 6; the tracking area corresponding to satellite 2 is tracking area 3; the tracking area corresponding to satellite 3 is tracking area 4 ", and the satellite base station corresponding to TA1 is determined Satellite 1 and notify AMF entity of Satellite 1;

由于AMF实体可以直接感知卫星基站，在确定所述终端当前所在的跟踪区域对应的卫星基站后，所述AMF实体向所述终端当前所在的跟踪区域对应的卫星基站发送寻呼请求，以使所述终端当前所在的跟踪区域对应的卫星基站进行寻呼；Since the AMF entity can directly sense the satellite base station, after determining the satellite base station corresponding to the tracking area where the terminal is currently located, the AMF entity sends a paging request to the satellite base station corresponding to the tracking area where the terminal is currently located, so that Paging the satellite base station corresponding to the tracking area where the terminal is currently located;

即AMF实体在接收到NRF实体返回的卫星1后，向卫星1发送寻呼请求。That is, after receiving the satellite 1 returned by the NRF entity, the AMF entity sends a paging request to the satellite 1.

具体的，如图5所示，为本申请实施例提供的第一种进行寻呼的整体方法流程图，具体的包括如下步骤；Specifically, as shown in FIG. 5, it is a flowchart of a first overall method for paging provided by an embodiment of the present application, and specifically includes the following steps;

步骤500，AMF实体接收到针对空闲态UE的下行信令/通知(Downlink signaling/notification，DL signaling/notification)；Step 500, the AMF entity receives downlink signaling / notification (Downlink signaling / notification, DL signaling / notification) for the idle UE;

步骤510，AMF实体从UE context中确定终端当前所在的跟踪区域；Step 510, the AMF entity determines the tracking area where the terminal is currently located from the UE context;

步骤520，AMF实体将终端当前所在的跟踪区域的区域标识发送给NRF实体；Step 520, the AMF entity sends the area identifier of the tracking area where the terminal is currently located to the NRF entity;

其中，NRF实体内部署有卫星信息管理实体；Among them, the satellite information management entity is deployed in the NRF entity;

步骤530，NRF实体根据卫星基站和当前覆盖区域中的跟踪区域的对应关系，确定获取到的所述终端当前所在的跟踪区域对应的卫星基站；Step 530: The NRF entity determines the acquired satellite base station corresponding to the tracking area where the terminal is currently located according to the correspondence between the satellite base station and the tracking area in the current coverage area;

步骤540，NRF实体将确定的所述终端当前所在的跟踪区域对应的卫星基站通知AMF实体；Step 540: The NRF entity notifies the AMF entity of the determined satellite base station corresponding to the tracking area where the terminal is currently located;

步骤550，AMF实体接收到所述NRF实体通知的卫星基站，并向所述卫星基站发送寻呼请求。In step 550, the AMF entity receives the satellite base station notified by the NRF entity, and sends a paging request to the satellite base station.

情况二：寻呼设备将寻呼请求通过地面基站发送给卫星基站，以通过卫星基站进行寻呼。Case 2: The paging device sends the paging request to the satellite base station through the ground base station to perform paging through the satellite base station.

卫星基站与AMF实体通过地面基站连接时的寻呼流程，卫星基站与AMF实体相连，AMF不能感知卫星基站的拓扑，即在AMF实体确定所述终端当前所在的跟踪区域对应的卫星基站后，不能感知到卫星基站，需要与所述卫星基站对应的地面基站将寻呼请求转发给卫星基站，以通过所述卫星基站进行寻呼。The paging process when the satellite base station and the AMF entity are connected by the ground base station. The satellite base station is connected to the AMF entity. The AMF cannot perceive the topology of the satellite base station. Sensing the satellite base station, the ground base station corresponding to the satellite base station needs to forward the paging request to the satellite base station to perform paging through the satellite base station.

具体的，AMF实体在接收到5G核心网触发的针对空闲态UE的下行信令时，AMF实体确定需要发起寻呼。Specifically, when the AMF entity receives downlink signaling triggered by the 5G core network for the idle UE, the AMF entity determines that paging needs to be initiated.

比如，AMF接收到针对UE1的下行信令后，确定UE1的注册区域为注册区域A，其中注册区域A中包含有跟踪区域1(TA1)和跟踪区域3(TA3)；所述AMF将确定UE1当前所处的跟踪区域为跟踪区域1和跟踪区域3。For example, after receiving the downlink signaling for UE1, AMF determines that the registration area of UE1 is registration area A, where registration area A contains tracking area 1 (TA1) and tracking area 3 (TA3); the AMF will determine UE1 The current tracking area is tracking area 1 and tracking area 3.

AMF实体将确定的所述终端当前所在的跟踪区域的区域标识发送给所述NRF实体，即发送给NRF实体内部的卫星信息管理实体，以使所述卫星信息管理实体根据自身存储的卫星基站和当前覆盖区域中的跟踪区域的对应关系，确定所述终端当前所在的跟踪区域对应的卫星基站，并将确定的所述终端当前所在的跟踪区域对应的卫星基站通知AMF实体；The AMF entity sends the determined area identifier of the tracking area where the terminal is currently located to the NRF entity, that is, to the satellite information management entity within the NRF entity, so that the satellite information management entity stores the satellite base station and Correspondence of the tracking areas in the current coverage area, determine the satellite base station corresponding to the tracking area where the terminal is currently located, and notify the AMF entity of the determined satellite base station corresponding to the tracking area where the terminal is currently located;

基于上述内容，AMF实体将确定UE1当前所处的跟踪区域为跟踪区域1和跟踪区域3对应的区域标识TA1和TA3发送给卫星信息管理实体；Based on the above, the AMF entity sends the tracking area 1 and the tracking area 3 corresponding to the tracking area 1 and the tracking area 3 to the satellite information management entity.

相应的，卫星信息管理实体中存储有“卫星1对应的跟踪区域为跟踪区域1、跟踪区域2、跟踪区域5、跟踪区域6；卫星2对应的跟踪区域为跟踪区域3；卫星3对应的跟踪区域为跟踪区域4”的对应关系，因此可以确定TA1对应的卫星基站为卫星1，TA3对应的卫星基站为卫星2，并将卫星1和卫星2通知AMF实体；Correspondingly, the satellite information management entity stores “the tracking area corresponding to satellite 1 is tracking area 1, tracking area 2, tracking area 5, and tracking area 6; the tracking area corresponding to satellite 2 is tracking area 3; the tracking corresponding to satellite 3 The area is the corresponding relationship of the tracking area 4 ", so it can be determined that the satellite base station corresponding to TA1 is satellite 1, and the satellite base station corresponding to TA3 is satellite 2, and the satellite 1 and satellite 2 are notified to the AMF entity;

由于AMF实体不能感知卫星基站的拓扑，因此AMF实体需要通过地面基站向卫星基站发送寻呼请求；Because the AMF entity cannot perceive the topology of the satellite base station, the AMF entity needs to send a paging request to the satellite base station through the ground base station;

在AMF实体接收到卫星信息管理实体通知的卫星基站后，AMF实体根据接收到的卫星信息管理实体通知的卫星基站及自身的配置信息确定卫星基站对应的地面基站，并向确定的地面基站发送寻呼请求，且所述寻呼请求中携带有卫星基站标识，或部分相关的卫星基站标识，以使所述地面基站在接收到携带有卫星基站标识的寻呼请求后，向所述卫星基站标识对应的卫星基站发送寻呼请求，进而所述卫星基站在对应的跟踪区域中发送寻呼消息；After the AMF entity receives the satellite base station notified by the satellite information management entity, the AMF entity determines the ground base station corresponding to the satellite base station according to the satellite base station notified by the satellite information management entity and its own configuration information, and sends a search to the determined ground base station A paging request, and the paging request carries a satellite base station identifier, or some related satellite base station identifiers, so that the ground base station receives the paging request carrying the satellite base station identifier, The corresponding satellite base station sends a paging request, and then the satellite base station sends a paging message in the corresponding tracking area;

根据上述内容可知，AMF实体接收到的卫星基站为卫星1和卫星2；若卫星1对应的地面基站为地面基站A，卫星2对应的地面基站为地面基站B；AMF实体向地面基站A发送携带有卫星1和跟踪区域的区域标识(TA1)的寻呼请求，向地面基站B发送携带有卫星2和跟踪区域的区域标识(TA3)的寻呼请求；According to the above, the satellite base stations received by the AMF entity are satellite 1 and satellite 2; if the ground base station corresponding to satellite 1 is ground base station A and the ground base station corresponding to satellite 2 is ground base station B; the AMF entity sends a carrier to ground base station A A paging request with the satellite 1 and the area identification (TA1) of the tracking area, sends a paging request with the satellite 2 and the area identification (TA3) of the tracking area to the ground base station B;

相应的，地面基站A向卫星1发送携带有跟踪区域的区域标识(TA1)的寻呼请求，以使所述卫星1在自身覆盖区域中的跟踪区域1中发送寻呼消息；地面基站B向卫星2发送携带有跟踪区域的区域标识(TA3)的寻呼请求，以使卫星2在自身覆盖区域中的跟踪区域3中发送寻呼消息。Correspondingly, the ground base station A sends a paging request carrying the area identification (TA1) of the tracking area to the satellite 1, so that the satellite 1 sends a paging message in the tracking area 1 in its coverage area; the ground base station B sends The satellite 2 sends a paging request carrying an area identifier (TA3) of the tracking area, so that the satellite 2 sends a paging message in the tracking area 3 in its coverage area.

具体的，如图6所示，为本申请实施例提供的第二种进行寻呼的整体方法流程图，具体的包括如下步骤；Specifically, as shown in FIG. 6, it is a flowchart of a second overall paging method provided by an embodiment of the present application, and specifically includes the following steps;

在实施中，当寻呼设备为AMF实体时，根据AMF实体是否可以感知到卫星基站，确定AMF实体是直接将寻呼请求发送给卫星基站，还是通过地面基站将寻呼请求转发给卫星基站，不论在那种情况下，AMF实体最终都通过确定的卫星基站进行寻呼，减少资源浪费。In the implementation, when the paging device is an AMF entity, it is determined whether the AMF entity directly sends the paging request to the satellite base station or forwards the paging request to the satellite base station through the ground base station according to whether the AMF entity can sense the satellite base station, In either case, the AMF entity will eventually page through the determined satellite base station to reduce resource waste.

实施例二：寻呼设备为地面基站。Embodiment 2: The paging device is a ground base station.

可选的，所述寻呼设备确定需要为终端进行寻呼时，所述寻呼设备在接收到携带有跟踪区域的区域标识的寻呼请求后确定需要为终端进行寻呼。Optionally, when the paging device determines that the terminal needs to be paged, the paging device determines that the terminal needs to be paged after receiving the paging request carrying the area identifier of the tracking area.

在本申请实施例中，所述地面基站接收到的携带有跟踪区域的区域标识的寻呼请求是由AMF实体在接收到5G核心网触发的DL signaling/notification后，AMF实体向所述地面基站发送的；In the embodiment of the present application, the paging request received by the ground base station carrying the area identifier of the tracking area is sent by the AMF entity to the ground base station after receiving the DL signaling / notification triggered by the 5G core network. Sent

具体的，AMF实体接收到5G核心网触发的DL signaling/notification后，AMF实体从UE context中确定当前UE的注册区域。由于UE的注册区域中包含有跟踪区域，因此AMF实体在确定UE的注册区域后，直接确定所述终端当前所处的跟踪区域；Specifically, after the AMF entity receives the DL signaling / notification triggered by the 5G core network, the AMF entity determines the current UE registration area from the UE context. Since the registration area of the UE includes a tracking area, after determining the registration area of the UE, the AMF entity directly determines the tracking area where the terminal is currently located;

所述AMF实体在确定当前UE的注册区域后，AMF实体根据UE的注册区域中所述终端当前所在的跟踪区域，确定当前服务该跟踪区域的地面基站；由于地面基站的覆盖区域固定，且AMF实体中存储有跟踪区域与地面基站的覆盖区域的对应关系；After the AMF entity determines the current registration area of the UE, the AMF entity determines the ground base station currently serving the tracking area according to the tracking area where the terminal is currently located in the registration area of the UE; since the coverage area of the ground base station is fixed and the AMF The correspondence between the tracking area and the coverage area of the ground base station is stored in the entity;

因此所述AMF实体在确定所述终端当前的跟踪区域后，可以确定地面基站的覆盖区域，进而可以确定覆盖区域对应的地面基站；Therefore, after determining the current tracking area of the terminal, the AMF entity can determine the coverage area of the ground base station, and then determine the ground base station corresponding to the coverage area;

AMF实体在确定服务于所述终端当前所在的跟踪区域的地面基站后，向所述地面基站发送携带有所述终端当前所在的跟踪区域的区域标识的寻呼请求，以使所述地面基站确定需要为终端进行寻呼，并通过所述终端当前所在的跟踪区域对应的卫星基站进行寻呼。After determining the ground base station serving the tracking area where the terminal is currently located, the AMF entity sends a paging request to the ground base station carrying the area identifier of the tracking area where the terminal is currently located, so that the ground base station determines The terminal needs to be paged, and the satellite base station corresponding to the tracking area where the terminal is currently located.

在实施中，当所述寻呼设备为地面基站时，地面基站接收到携带有跟踪区域的区域标识的寻呼请求后，确定需要为终端进行寻呼，说明当寻呼设备为地面基站时，地面基站不能随便的确定终端是否进行寻呼，而是在接收到特定的指令后才会确定终端需要寻呼，使执行寻呼流程更加的准确，减少资源浪费。In the implementation, when the paging device is a ground base station, after receiving the paging request carrying the area identifier of the tracking area, the ground base station determines that the terminal needs to be paged, indicating that when the paging device is a ground base station, The ground base station cannot casually determine whether the terminal performs paging, but determines that the terminal needs to be paged after receiving a specific instruction, which makes the paging process more accurate and reduces waste of resources.

本申请实施例中，寻呼设备为地面基站时，地面基站通过下列方式确定所述终端当前所在的跟踪区域对应的卫星基站：In the embodiment of the present application, when the paging device is a ground base station, the ground base station determines the satellite base station corresponding to the tracking area where the terminal is currently located in the following manner:

在卫星基站与AMF实体通过地面基站连接的场景，当地面基站具有更新及存储卫星基站和当前覆盖区域中的跟踪区域的对应关系时，地面基站可以根据寻呼请求中携带的所述终端当前所在的跟踪区域的区域标识确定跟踪区域，并根据自身中存储的卫星基站和当前覆盖区域中的跟踪区域的对应关系确定卫星基站；In the scenario where the satellite base station and the AMF entity are connected through the ground base station, and the ground base station has updated and stored the correspondence relationship between the satellite base station and the tracking area in the current coverage area, the ground base station may be based on the current location of the terminal carried in the paging request Determine the tracking area by the area identifier of the tracking area, and determine the satellite base station according to the correspondence between the stored satellite base station and the tracking area in the current coverage area;

比如，地面基站接收到的寻呼请求中携带的跟踪区域的区域标识为TA1，TA1表示跟踪区域1；地面基站中更新存储的对应关系为：卫星1当前覆盖的跟踪区域为跟踪区域1、跟踪区域2、跟踪区域5、跟踪区域6，卫星2当前覆盖的跟踪区域为跟踪区域3，卫星3当前覆盖的跟踪区域为跟踪区域4；For example, the area identifier of the tracking area carried in the paging request received by the ground base station is TA1, and TA1 represents tracking area 1; the corresponding relationship updated and stored in the ground base station is: the tracking area currently covered by satellite 1 is tracking area 1, tracking Area 2, tracking area 5, tracking area 6, the tracking area currently covered by satellite 2 is tracking area 3, and the tracking area currently covered by satellite 3 is tracking area 4;

根据确定的跟踪区域及地面基站中更新存储的对应关系确定跟踪区域1对应的卫星基站为卫星1，因此确定所述终端当前所在的跟踪区域对应的卫星基站为卫星1；Determining that the satellite base station corresponding to the tracking area 1 is the satellite 1 according to the determined tracking area and the updated stored correspondence in the ground base station, and therefore determining that the satellite base station corresponding to the tracking area where the terminal is currently located is the satellite 1;

地面基站在确定所述终端当前所在的跟踪区域对应的卫星基站为卫星1后，向所述卫星1发送携带有所述终端当前所在的跟踪区域的区域标识的寻呼请求，以使所述卫星1在根据接收到的跟踪区域的区域标识，在自身当前覆盖区域中跟踪区域的区域标识对应的跟踪区域发送寻呼消息。After determining that the satellite base station corresponding to the tracking area where the terminal is currently located is the satellite 1, the ground base station sends a paging request to the satellite 1 carrying the area identifier of the tracking area where the terminal is currently located, so that the satellite 1 Send a paging message in the tracking area corresponding to the area identification of the tracking area in the current coverage area according to the received area identification of the tracking area.

在实施中，地面基站根据接收到的区域标识确定跟踪区域，并根据对应关系确定终端当前所在的跟踪区域对应的卫星基站，地面基站可以准确的确定出当前覆盖所述终端当前所在的跟踪区域的卫星基站，进而通过当前覆盖所述终端当前所在的跟踪区域的卫星基站进行寻呼，使发送寻呼更加的准确顺利，减少资源浪费。In the implementation, the ground base station determines the tracking area according to the received area identifier, and determines the satellite base station corresponding to the tracking area where the terminal is currently located according to the correspondence. The ground base station can accurately determine the current coverage area of the tracking area where the terminal is currently located. The satellite base station, and then paging through the satellite base station currently covering the tracking area where the terminal is currently located, makes paging transmission more accurate and smooth, and reduces waste of resources.

本申请实施例中，所述寻呼设备根据下列方式确定所述卫星基站和当前覆盖区域中的跟踪区域的对应关系：In the embodiment of the present application, the paging device determines the correspondence between the satellite base station and the tracking area in the current coverage area according to the following manner:

具体的，卫星基站实时获取自身的星历信息和天线参数，并将获取到的星历信息和天线参数发送给地面基站；Specifically, the satellite base station obtains its own ephemeris information and antenna parameters in real time, and sends the obtained ephemeris information and antenna parameters to the ground base station;

相应的，地面基站接收到卫星基站上报的星历信息和天线参数后，根据上报的星历信息和天线参数推算卫星波束的照射范围，即卫星基站当前覆盖区域；Correspondingly, after receiving the ephemeris information and antenna parameters reported by the satellite base station, the ground base station estimates the irradiation range of the satellite beam according to the reported ephemeris information and antenna parameters, that is, the current coverage area of the satellite base station;

所述地面基站在确定卫星基站当前覆盖区域后，根据预先规划的跟踪区域，确定卫星基站当前覆盖区域中的跟踪区域是否有变化，若所述卫星基站当前覆盖区域发生变化，则所述卫星基站当前覆盖区域中的跟踪区域发生变化，确定卫星基站当前覆盖区域中的跟踪区域，并根据确定的卫星基站当前覆盖内的跟踪区域，确定卫星基站和当前覆盖区域中的跟踪区域的对应关系；具体的参见卫星信息管理实体的实施方式。After determining the current coverage area of the satellite base station, the ground base station determines whether the tracking area in the current coverage area of the satellite base station changes according to the pre-planned tracking area. If the current coverage area of the satellite base station changes, the satellite base station The tracking area in the current coverage area changes, determine the tracking area in the current coverage area of the satellite base station, and determine the correspondence between the satellite base station and the tracking area in the current coverage area based on the determined tracking area within the current coverage of the satellite base station; See the implementation of satellite information management entity.

需要说明的，所述地面基站不仅有对所述卫星基站和当前覆盖区域中的跟踪区域的对应关系的更新功能，还有将更新后的对应关系进行存储的功能。It should be noted that the ground base station not only has the function of updating the correspondence between the satellite base station and the tracking area in the current coverage area, but also has the function of storing the updated correspondence.

在实施中，地面基站可以根据卫星基站的星历信息和天线参数确定卫星当前覆盖区域，由于跟踪区域是预先设定的，因此跟踪区域的位置不会发生变化，当卫星基站当前覆盖区域发生变化后，卫星基站当前覆盖区域中的跟踪区域就会发生变化，确定卫星基站和当前覆盖区域中的跟踪区域，由于对应关系可以根据卫星基站的覆盖区域实时更新，因此在根据跟踪区域确定卫星基站后，确定的卫星基站一定是覆盖该跟踪区域的卫星基站，在通过覆盖该跟踪区域的卫星基站进行寻呼时，准确寻呼，减少资源。In the implementation, the ground base station can determine the current coverage area of the satellite according to the ephemeris information and antenna parameters of the satellite base station. Since the tracking area is preset, the location of the tracking area will not change. When the current coverage area of the satellite base station changes After that, the tracking area in the current coverage area of the satellite base station will change. Determine the tracking area in the satellite base station and the current coverage area. Since the correspondence can be updated in real time according to the coverage area of the satellite base station, after determining the satellite base station according to the tracking area The determined satellite base station must be the satellite base station covering the tracking area. When paging through the satellite base station covering the tracking area, accurate paging will reduce resources.
