Description

一种通信方法和装置
本申请要求于2019年07月02日提交中国专利局、申请号为201910597933.6、申请名称为“一种通信方法和装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域，尤其涉及一种通信方法和装置。
背景技术
随着科学技术的不断发展，为了提供更加广域的无线网络覆盖，以解决海上、偏远地区等无地面移动网络(又称地面蜂窝网络，下文以地面蜂窝网络代替描述)覆盖地区的通信服务，卫星和非陆地通信网络(satellites and non-terrestrial networks，NTN)作为地面蜂窝网络的重要补充，其应用范围也越来越广泛。而随着卫星及非陆地网络与地面蜂窝网络的相结合，如何合理在卫星及非陆地网络和地面蜂窝网络中对终端设备进行位置管理成为了当前一大研究热点。
现有技术一般是通过跟踪区及注册区在卫星和非地面通信网络(下文简述为卫星通信网络)与地面蜂窝网路中实现对终端设备进行位置管理的。即，在地球表面先静态划定出多个区域，每个区域就是一个跟踪区。当终端设备接入到卫星通信网络和/或地面蜂窝网络后，其会向核心网设备发起初始注册、移动性注册更新或者周期性注册更新等请求。然后，核心网可根据终端设备的上下文等信息为终端设备确定出用于指示一个或者多个跟踪区的注册区信息，并通过基站(即通信卫星和/或地面基站)将该注册区信息配置给终端设备，从而实现了对终端设备的位置管理。但是，在终端设备所连接的服务小区所广播的跟踪区列表不断发生变化的场景下，核心网设备基于终端设备的上下文等信息为终端设备配置的注册区信息准确率低，无法准确的表征出终端设备的地理位置，容易导致终端设备频繁的向核心网发起注册区信息更新请求等问题，从而造成了通信网络的通信资源的浪费，降低了通信网络的通信资源利用率和适用性。
发明内容

在本申请实施例中，终端设备通过基站向核心网设备发送其在第一预设时段内收听到的一个或者多个第一跟踪区的收听频繁指数，以使得核心网设备可基于各第一跟踪区的收听频繁指数为其确定出第一注册区信息。由于核心网设备基于各第一跟踪区的收听频繁指数确定 出的注册区信息的精度更高，能够更为准确的表征出终端设备的地理位置，避免了终端设备因注册区信息不准确而频繁的向核心网设备发起注册更新请求的问题，也为终端设备进行小区重选等操作提供了便利，从而减少了通信网络的通信资源的浪费，提升了通信网络的通信资源利用率和适用性。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述。
本申请实施例提供的通信方法所适用的通信系统可以是采用了异步卫星的卫星及非地面通信系统(下文将简化为卫星通信系统)。这里，上述卫星通信系统可包括的低轨道卫星通信系统、中轨道卫星通信系统或者高轨道卫星通信系统。本申请实施例提供的通信方法还适用于采用了移动基站的地面通信系统，如采用了移动基站的4G通信系统或5G通信系统等。这里，可以理解到的是，上述地面通信系统还可以是其他采用各种无线接入技术的无线通信系统，例如采用码分多址(code division multiple access，CDMA)，频分多址(frequency division multiple access，FDMA)，时分多址(time division multiple access，TDMA)，正交频分多址(orthogonal frequency division multiple access，OFDMA)，单载波频分多址(single carrier-frequency division multiple access，SC-FDMA)，多输入多输出(multiple input multiple output，MIMO)等接入技术的系统。本申请实施例提供的通信方法还适用于由采用了移动卫星的卫星通信系统和采用了移动基站的地面通信系统构成的广域通信服务系统，此处不作限定。
本申请实施例提供的通信方法所涉及的设备主要包括终端设备(user equipment，UE)和 网络设备。上述终端设备具体可以为向用户提供语音和/或数据连通性的无线设备。该无线设备可以是具有无线连接功能的手持式设备、连接到无线调制解调器的其他处理设备或经无线接入网与一个或多个核心网进行通信的移动设备。例如，该无线设备可以为移动电话、计算机、平板电脑、个人数码助理(personal digital assistant，PDA)、移动互联网设备(mobile Internet device，MID)、可穿戴设备和电子书阅读器(e-book reader)等。又如，该无线设备也可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动设备。再如，该无线设备还可以为移动站(mobile station)、接入点(access point)。为方便描述，在本申请实施例中将以终端设备为例进行说明。上述网络设备主要包括基站和核心网设备。需要说明的是，在卫星通信系统中，若其异步卫星为透明卫星(transparent satellite)，则上述网络设备中的基站指代的就是该异步卫星。若该异步卫星为再生卫星(regenerative satellite)，则该异步卫星仅用于转发终端设备与基站之间的信息，这种情况下上述基站主要指代是部署在无线接入网(radio access network,RAN)中用以为终端设备提供无线通信功能的地面装置和设备。该地面装置或设备可以包括各种形式的宏基站，微基站，中继站，接入点基站控制器，收发节点(transmission reception point,TRP)等等。上述核心网设备是一种部署在核心网(core network,CN)中为终端设备提供用户连接、移动性管理、补充业务实现、智能触发等功能的装置。在卫星通信系统中，上述核心网设备主要包括网元有移动性管理单元、在线计费单元、业务网关等。
在本申请实施例中，将以异步卫星构成的卫星通信系统为例，对本申请实施例提供的通信方法所涉及的通信系统及其工作过程进行简单的描述。请参见图1，图1是本申请实施例提供的通信系统架构示意图。图1所示的通信卫星为异步的透明卫星，即该通信系统中的基站即使该异步卫星，并且基站与地面之间处于相对移动状态。在该卫星通信系统中，基站通过方向不同的波束在地面形成多个卫星通信小区，如图1中所示的卫星通信小区1、卫星通信小区2和卫星通信小区3。当终端设备与某一卫星通信小区建立连接后，即可与基站进行信息互传。基站在接收到终端设备发送的信息后，可将该信息转发给地面上的卫星网关(又可称之为地球站)。然后，卫星网关可通过诸如光缆等传输设备将该信息发送给核心网设备。同理，核心网设备也可通过上述通信链路将信息发送至终端设备，从而实现信息在终端设备和核心网之间的互传。
下面将结合图1所示的通信系统结构示意图对本申请实施例涉及到的相关概念进行简单的解释和说明。
1、跟踪区(tracking area，TA)
跟踪区是通信系统为终端设备的位置管理设定的概念，其被定义为终端设备不需要更新服务的自由移动区域。它类似于2G通信系统或者3G通信系统中的位置区或者路由区。在某一通信系统中，跟踪区域通常是预先静态划定好的，并且每个跟踪区之间不存在重叠区域。如图1中所示的跟踪区TA1、跟踪区TA2、跟踪区TA3和跟踪区TA4。实际应用中，一个跟踪区会由一个跟踪区号(tracking area indicator，TAI)来标识，如上述跟踪区TA1即可由跟踪区号“TA1”来标识。在如图1所示的通信系统中，基站会根据其在地面形成的一个或者多个卫星通信小区在不同时刻上与预先划定好的跟踪区的覆盖关系确定出每个卫星通信小区在不同时刻所关联一个或者多跟踪区，并将这一个或者多个跟踪区的信息以跟踪区列表的形式在每个卫星通信小区内广播。这里，卫星通信小区在某一时刻所关联的跟踪区就是与该卫星通信小区存在重叠区域的跟踪区。通常情况下，基站主要是通过系统信息块1来携带这个跟踪区列表，并周期性在卫星通信小区内。具体实现中，该跟踪区列表中可包含一条或多条跟 踪区信息，每条跟踪区信息中可包括通信网络标识和跟踪区标识。比如，跟踪区TA1在跟踪区列表中对应的跟踪区信息具体可为[PLMN A,TA1]，跟踪区TA2在注册区列表中对应的跟踪区信息具体可为[PLMN A,TA2]。例如，基站通过波束在地面形成了卫星通信小区1、卫星通信小区2和卫星小区3这3个卫星通信小区。在某一时刻，基站通过卫星通信小区1的位置信息和预先划定出的各跟踪区的位置信息确定出卫星通信小区1与跟踪区TA1和跟踪区TA4存在重叠区域，则基站在卫星通信小区所广播的系统信息块1中就会包含一个跟踪区列表，该跟踪区列表中具体包含[PLMN A,TA1]和[PLMN A,TA4]这两条跟踪区信息。同理，基站通过卫星通信小区2的位置信息和上述各跟踪区的位置信息确定卫星通信小区2在该时刻与跟踪区TA1、跟踪区TA2、跟踪区TA3和跟踪区TA4存在重叠区域，则在卫星通信小区2中所广播的系统信息块1中就会包含[PLMN A,TA1]、[PLMN A,TA2]、[PLMN A,TA3]和[PLMN A,TA4]这四条跟踪区信息。
2、注册区(registration area，RA)
注册区是由一个或者多个跟踪区组成，为终端设备可自由移动且不需要进行注册区信息更新的区域。当终端设备向核心网设备发起初始注册、移动性注册更新或者周期性注册更新的请求后，核心网设备通常会根据该终端设备对应的上下文等信息确定出终端设备所关联的注册区信息，并通过注册更新接收消息(registration accept)将上述注册区信息下发给终端设备。这里，上述注册区信息用于为终端设备配置其所关联注册区。换句话说，就是这个注册区信息指示了终端设备当前所关联的一个或者多个跟踪区。这里，一个注册区信息可等同于前文上述的一个跟踪区列表。通常来说，终端设备在首次开机后会首先会向核心网发起初始注册，以获取一个初始的注册区信息(下文将以初始注册区信息代替描述)。终端设备在得到初始注册区信息后，若检测到预设的注册更新触发条件满足时，会再向核心网发起移动性注册更新请求或者周期性注册更新请求以请求核心网设备下发一个新的注册区信息，并通过这个新的注册区信息来更新上述初始注册区信息，此时，终端设备所关联的跟踪区就变成了这个新的注册区信息所指示的跟踪区。同理，当终端设备再次检测到注册更新触发条件时，会重复上述操作。例如，请一并参见图1，假设某一终端设备开机后的服务小区是卫星通信小区2，其初始注册区信息中包括TA2和TA3，即其注册区包括跟踪区TA2和跟踪区TA3。然后，随着卫星在移动方向A上的高速移动，在某一时刻卫星通信小区2所广播的跟踪区只有跟踪区TA1和跟踪区TA4，则终端设备可确定其初始注册区信息所指示的跟踪区与其收听到的跟踪区不存在交集，则终端设备会向核心网设备发起一次移动性注册更新请求。又比如，当终端设备检测到预设的注册更新周期到达时，还可向核心网设备发起周期性注册更新。
如图1所示的通信系统中，终端设备所接收到注册区信息是由核心网设备根据终端设备的上下文等信息确定出的。但是，由于基站所形成的卫星通信小区会随着基站的高速移动而移动，这样就会造成卫星通信小区中广播的跟踪区列表会随着时间的推移而快速变化。对于与地面处于相对静止状态或者移动速度慢的终端设备来说，由于其接入的卫星通信小区所关联的注册区信息不断在变化，核心网设备根据终端设备的上下文等信息确定出的注册区信息与终端设备连接的卫星通信小区所对应的注册区信息就会不匹配，使得核心网设备为终端设备配置的注册区信息无法准确的表征出终端设备的地理位置，从而造成终端设备频繁的向核心网发起注册更新请求等问题。这就会通信网络的通信资源的浪费，从而降低了通信系统的实用性。
本申请提供的通信方法所要解决的技术问题是：如何提升注册区信息准确度，从而避免 终端设备因注册区信息不准确而造成的通信资源的浪费，提升通信网络的通信资源利用率和实用性。
实施例一
请参见图2，图2是本申请实施例提供的一种通信方法一流程示意图。由图2可知，上述通信方法包括以下步骤：
S101，终端设备确定出其在第一预设时段内收听到的一个或者多个第一跟踪区中各第一跟踪区的收听频繁指数。
在一些可行的实施方式中，当终端设备确定需要向网络设备发送第一消息时，可先确定出其在第一预设时段内收听到的一个或者多个跟踪区(为方便区别，下文以第一跟踪区代替描述)中各第一跟踪区的收听频繁指数。这里，各第一跟踪区所对应的收听频繁指数主要用于表示终端设备在第一预设时段内收听到各第一跟踪区的频繁程度。上述第一预设时段为终端设备确定需要向基站发送第一消息之前的一个时段。这里，第一预设时段的具体时长可为对本申请提出的通信方法进行多次试验得到的经验值。
具体实现中，当终端设备确定要向网络设备发送第一消息时，可先获取跟踪区收听历史记录。这里，上述跟踪区收听历史记录中包括有终端设备已经收听到的一条或者多个跟踪区所对应的标识以及终端设备收听到各跟踪区的收听时刻。其中，一个跟踪区对应一个或多个收听时刻。可选的，上述跟踪区收听历史记录可保存于终端设备自身的存储器中，也可保存于与终端设备相连接的云存储器中，此处不作限定。另外，还需要说明的是，每当检测到预设的广播周期到达或者其卫星通信小区所关联的跟踪区发生变化时，基站会在其形成的各个卫星通信小区中通过广播消息广播各卫星通信小区当前时刻所对应的跟踪区列表。这样，当终端设备通过卫星通信小区A与基站建立通信连接后，终端设备可在不同的时刻从基站处收听到携带有跟踪区列表的广播消息。终端设备在某一时刻从基站处收听到携带有跟踪区列表的广播消息后，可将该跟踪区列表中所包含的一个或者多个跟踪区的标识和该时刻保存至上述跟踪区收听历史记录中。实际应用中，上述跟踪区收听历史记录具体可以是一个跟踪区收听历史记录表，如表1-1所示。表1-1是本申请实施例提供的一种跟踪区收听历史记录表。由该表可知，终端设备在t0时刻收听到了跟踪区TA1和TA2，在t1时刻收听到了跟踪区TA，以此类推。
表1-1
Figure PCTCN2020098644-appb-000001
终端设备在获取到上述跟踪区收听历史记录后，可从上述跟踪区收听历史记录中提取出其在第一预设时段内的跟踪区收听历史记录(为方便区别，下文以目标收听历史记录代替描 述)，并根据上述目标收听历史记录中包含的一个或者多个跟踪区的标识和各个跟踪区标识所对应的一个或者多个时刻确定出终端设备在上述第一预设时段内收听到的一个或者多个第一跟踪区以及各第一跟踪区对应的收听参数。这里，上述第一预设时段的终止时刻为终端设备确定需要发送第一消息的时刻。本申请实施例提供了两种各第一跟踪区对应的收听参数的确定方式，包括收听参数确定方式一和收听参数确定方式二。
收听参数确定方式一：
终端设备在获取到上述目标收听历史记录后，可基于该目标收听历史记录中包含的跟踪区的标识确定出其在上述第一预设时段内收听到的一个或者多个第一跟踪区。然后，终端设备还可根据上述目标收听历史记录中包含的各第一跟踪区的收听时刻确定出各第一跟踪区在第一预设时段内对应的收听时长。然后，终端设备可将各第一跟踪区对应的收听时长确定为各第一跟踪区对应的收听参数。或者，终端设备还可将各第一跟踪区的标识和各第一跟踪区对应的收听时长共同确定为各第一跟踪区的收听参数。下文将以各第一跟踪区对应的收听时长为各第一跟踪区对应的收听参数这一场景为例对各第一跟踪区的收听参数的确定过程进行说明。例如，请一并参见表1-1，假设上述第一预设时段的起始时刻为t2，终止时刻为t6，终端设备分别在t2、t3、t4、t5和t6这5个时刻收听到了基站广播的跟踪区信息。对于第一跟踪区TA1来说，终端设备分别在t2、t3、t5和t6这4个时刻收听到了第一跟踪区TA1，则终端设备可确定出第一跟踪区TA1所对应的收听时长为t4-t2+t6-t5，即第一跟踪区TA1对应的收听参数为t4-t2+t6-t5。同理，对于第一跟踪区TA2来说，终端设备在t3时刻收听到第一个跟踪区TA2，则终端设备可确定第一跟踪区TA2对应的收听时长为t4-t3，即第一跟踪区TA2对应的收听参数为t4-t3。以此类推，此处便不再赘述。
收听参数确定方式二：
终端设备在获取到其在上述目标收听历史记录后，可基于该目标收听历史记录中包含的跟踪区的标识确定出其在上述第一预设时段内收听到的一个或者多个第一跟踪区。然后，终端设备还可根据上述目标收听历史记录中包含的各第一跟踪区的收听时刻确定出各第一跟踪区在第一预设时段内对应的收听次数。然后，终端设备可将各第一跟踪区对应的收听次数确定为各第一跟踪区对应的收听参数。或者，终端设备也可将各第一跟踪区的标识和各第一跟踪区对应的收听次数确定为各第一跟踪区的收听参数。下文将以各第一跟踪区对应的收听次数为各第一跟踪区对应的收听参数这一场景为例对各第一跟踪区的收听参数的确定过程进行举例说明。例如，请一并参见表1-1，假设上述第一预设时段的起始时刻为t2，终止时刻为t6，终端设备分别在t2、t3、t4、t5和t6这5个时刻收听到了基站广播的跟踪区信息。对于第一跟踪区TA1来说，终端设备分别在t2、t3、t5和t6这4个时刻收听到了第一跟踪区TA1，则终端设备可确定出第一跟踪区TA1所对应的收听次数为4，即第一跟踪区TA1对应的收听参数为4。同理，对于第一跟踪区TA2来说，终端设备在t3时刻收听到第一个跟踪区TA2，则终端设备可确定第一跟踪区TA2对应的收听次数为1，即第一跟踪区TA2对应的收听参数为1。以此类推，此处便不再赘述。
在终端设备确定出各第一跟踪区对应的收听参数后，其可根据各第一跟踪区的收听参数和上述第一预设时段确定出各第一跟踪区对应的收听频繁指数。在一种可选方式中，当各第一跟踪区对应的收听参数是各第一跟踪区的收听时长时，终端设备可分别计算出各第一跟踪区的收听时长与上述第一预设时段的比值，并将各第一跟踪区所对应的收听时长和第一预设时段的比值确定为各第一跟踪区的收听频繁指数。当各第一跟踪区对应的收听参数是各第一 跟踪区的收听次数时，终端设备可分别计算出各第一跟踪区的收听次数与上述第一预设时段的比值，并将各第一跟踪区对应的收听次数和第一预设时段的比值确定为各第一跟踪区的收听频繁指数。在另一种可选方式中，在终端设备计算出各第一跟踪区的收听时长或者收听次数与上述第一预设时段的比值后，终端设备可基于预设的离散区间对各第一跟踪区的收听时长或者收听次数与第一预设时段的比值进行离散化，以得到各第一跟踪区的收听时长或者收听次数与第一预设时段的比值的离散值，然后将各第一跟踪区所对应的离散值确定为各第一跟踪区的收听频繁指数。这里，对各第一跟踪区的收听时长或者收听次数与第一预设时段的比值进行离散并将离散值作为各第一跟踪区的收听频繁指数，可使得后续第一消息中能使用整型数来表征各第一跟踪区的收听频繁指数，有利于节省通信网络的信令开销。
下面以收听参数为收听时长为例，对终端设备确定出各第一跟踪区的收听频繁指数的过程进行举例说明。请一并参见表1-1，这里假设t0时刻为第0分钟，t1时刻为第10分钟，t2时刻为第20分钟，以此类推，t6时刻为第60分钟。上述第一预设时段起始时刻为t2，终止时刻为t6，总时长为40分钟。由表中内容可知，第一跟踪区TA1在第一预设时长内的收听时长为30分钟。第一跟踪区TA2在第一预设时长内的收听时长为10分钟。第一跟踪区TA3在第一预设时长内的收听时长为40分钟。第一跟踪区TA4在第一预设时长内的收听时长为10分钟。这样，终端设备可确定出第一跟踪区TA1对应的收听时长与第一预设时长的比值为0.75，第一跟踪区TA2对应的收听时长与第一预设时长的比值为0.25。第一跟踪区TA3对应的收听时长与第一预设时长的比值为1。第一跟踪区TA4对应的收听时长与第一预设时长的比值为0.25。然后，终端设备可确定第一跟踪区TA1、第一跟踪区TA2、第一跟踪区TA3和第一跟踪区TA4对应收听频繁指数分别为0.75、0.25、1和0.25。或者，终端设备在确定第一跟踪区TA1、第一跟踪区TA2、第一跟踪区TA3和第一跟踪区TA4对应比值分别为0.75、0.25、1和0.25之后，可根据预设的离散区间对上述4个比值进行离散化。这里假设第一离散区间为[0,0.25]，其对应的离散值为1，第二离散区间为[0.26,0.5]，其对应的离散值为2，第三离散区间为[0.51,0.75]，其对应的离散值为3，第四离散区间为[0.76,1]，其对应的离散值为4。终端设备对上述4个比值进行离散化后，可确定第一跟踪区TA1、第一跟踪区TA2、第一跟踪区TA3和第一跟踪区TA4对应的离散值分别为3、1、4和1，即第一跟踪区TA1的收听频繁指数为3，第一跟踪区TA2的收听频繁指数为1，第一跟踪区TA3的收听频繁指数为4，第一跟踪区TA4的收听频繁指数为1。
需要补充说明的是，在一些可行的实施方式中，终端设备在检测到预设的通信触发条件时，确定向基站发送上述第一消息。
在一种可选的方中，上述通信触发条件可为终端设备在检测到预设的通信周期到达，即当终端设备检测到通信周期到达时，可确定其需要向基站发送上述第一消息。这里，上述通信周期可为对本申请提出的通信方法进行多次试验得到的经验值。
在又一种可选的方式中，上述通信触发条件为终端设备收听到的一个或者多个第二跟踪区与终端设备上一次注册区信息更新得到的注册区信息(为方便区别，下文以第二注册区信息代替描述)所指示的一个或者多个第三跟踪区均不相同。即每当终端设备收听到由基站广播的跟踪区列表时，若终端设备检测到该跟踪区列表所包含的一个或者多个跟踪区(即第二跟踪区)与终端设备上一次注册区信息更新所得到的第二注册区信息所指示的一个或者多个跟踪区(即第三跟踪区)中不存在相同的跟踪区，则可确定其需要向基站发送第一消息。这里，上述第一消息具体可为注册更新请求消息。
在又一种可选的方式中，上述通信触发条件包括一个或者多个判决跟踪区的一个或者多个收听频繁指数之和小于触发判决阈值。上述判决跟踪区为终端设备收听到的一个或者多个第二跟踪区和终端设备上一次注册区信息更新得到的第二注册区信息所指示的一个或者多个第三跟踪区中相同的跟踪区。即每当终端设备收听到由基站广播的一个或者多个第二跟踪区后，其可将上述一个或者多个第二跟踪区中与终端设备上一次注册区信息更新得到的一个或者多个第三跟踪区中相同的一个或者多个跟踪区确定为判决跟踪区。然后，终端设备可根据第二预设时段和各判决跟踪区在上述第二预设时段内对应的收听参数确定出上述各判决跟踪区的收听频繁指数。这里，上述第二预设时段的终止时刻为终端设备收听到由基站广播的一个或者多个第二跟踪区的时刻。终端设备确定出各判决跟踪区的收听频繁指数的过程可参见前文上述的确定各第一跟踪区的收听频繁指数的过程，此处便不再赘述。然后，终端设备可确定出上述各判决跟踪区的收听频繁指数之和，并将各判决跟踪区的收听频繁指数之和与预设的触发判决阈值进行比较。若终端设备确定出各判决跟踪区的收听频繁指数之和小于上述触发判决阈值，则确定其需要向基站发送上述第一消息。若终端设备确定出各判决跟踪区的收听频繁指数之和等于或者大于上述触发判决阈值，可继续等待新的第二跟踪区，并重复上述判断操作。
在一些可行的方式中，上述第一消息还包括终端设备检测到上述通信触发条件之前最后一次收听到的一个或者多个跟踪区(为方便区别，下文将以第四跟踪区代替描述)。这里，上述一个或者多个第四跟踪区后续可用于确定第一注册区信息。可选的，上述第一注册区信息可用于更新终端设备上一次注册区信息更新得到的第二注册区信息。上述第一注册区信息还可用于终端设备进行小区重选。可以理解到的是，这里所叙述的第一注册区信的作用并不是其全部作用，此处仅是举例说明，不做具体限定。
S102，终端设备向基站发送包含有上述各第一跟踪区的收听频繁指数的第一消息。
在一些可行的实现方式中，终端设备在确定出上述各第一跟踪区的收听频繁指数后，可根据终端设备与基站之间的通信协议对上述收听频繁指数进行打包，以得到包含有上述各第一跟踪区的收听频繁指数的第一消息。可选的，具体实现中，终端设备可先根据上述各第一跟踪区的收听频繁指数确定出一个收听频繁指数字段，该收听频繁指数字段中包含了各第一跟踪区的标识和各第一跟踪区的收听频繁指数。然后，终端设备可将上述收听频繁指数字段打包在注册更新请求消息中，以得到第一消息。终端设备在得到上述第一消息后，即可在基站为其分配信道资源上向基站发送上述第一消息。
S103，基站接收上述第一消息，并向核心网设备转发上述第一消息。
在一些可行的实施方式中，基站(即通信卫星)在上述信道资源上接收到终端设备发送的第一消息后，可通过卫星网关和传输设备将上述第一消息转发至核心网设备。这里，基站发送给核心网设备消息可以是未经其修改的第一消息，也可以是基站基于其与核心网设备之间的通信协议修改后的第一消息(为方便理解，下文以第三消息代替描述)。可以理解到的是，上述第三消息至少包含的各第一跟踪区的收听频繁指数。
S104，核心网设备接收上述第一消息，并根据各第一跟踪区的收听频繁指数确定出第一注册区信息。
在一些可行的实施方式中，核心网设备可通过传输设备从基站处接收到上述第一消息或者第三消息。然后从上述第一消息或者第三消息中提取出个第一跟踪区的收听频繁指数，并根据各第一跟踪区的收听频繁指数确定出第一注册区信息。
当上述第一消息中不包含上述一个或者多个第四跟踪区时，在一种可选的具体实现中，核心网设备在获取到各第一跟踪区的收听频繁指数后，可再获取预设的收听频繁指数阈值。然后，核心网设备可从上述各第一跟踪区中筛选出一个或者多个目标跟踪区。这里，上述目标跟踪区就是收听频繁指数等于或者大于上述收听频繁指数阈值的第一跟踪区。最后，核心网设备根据上述各第一跟踪区的标识确定出上述各目标跟踪区的标识，并根据上述各目标跟踪区的标识确定出第一注册区信息。这里，上述第一注册区信息中包括了上述各目标跟踪区的标识。
在另一种可选的具体实现中，核心网设备在获取到各第一跟踪区的收听频繁指数后，可获取预设的收听频繁指数阈值。然后，核心网设备可先按照从大到小的顺序对各第一跟踪区的收听频繁指数进行排序，并判断排列顺序为第一位的收听频繁指数是否等于或者大于上述收听频繁指数阈值。若核心网设备确定出排列顺序为第一位的收听频繁指数等于或者大于上述收听频繁指数阈值，则可将排列顺序为第一位的收听频繁指数所对应的第一跟踪区确定为目标跟踪区。若核心网设备确定出排列顺序为第一位的收听频繁指数小于上述收听频繁指数阈值，则可计算出排列顺序为第一位和排列顺序为第二位的收听频繁指数的和值，并判断该和值是否等于或者大于上述收听频繁指数阈值。若核心网设备确定出上述和值等于或者大于上述收听频繁指数阈值，则可将排列顺序为第一位和排列顺序为第二位的收听频繁指数所对应的两个第一跟踪区均确定为目标跟踪区。若核心网设备确定出上述和值小于上述收听频繁指数阈值，则可继续挑选出排列顺序为第一位、排列顺序为第二位和排列顺序为第三位的收听频繁指数，并重复上述求和与判断操作，直至确定出收听频繁指数排列顺序靠前，且收听频繁指数之和等于或者大于上述收听频繁指数阈值的一个或者多个目标跟踪区。换句话说，即核心网设备可根据收听频繁指数阈值和各第一跟踪区的收听频繁指数从上述一个或者多个第一跟踪区中确定出一个或者多个目标跟踪区，且上述一个或者多个目标跟踪区的收听频繁指数均大于非目标跟踪区的收听频繁指数。这里，上述非目标跟踪区为上述一个或者多个第一跟踪区中除一个或者多个目标跟踪区以外的第一跟踪区。最后，核心网设备可根据上述各第一跟踪区的标识确定出上述各目标跟踪区的标识，并根据上述各目标跟踪区的标识确定出第一注册区信息。
在本申请实施例中，基于各第一跟踪区的收听频繁指数来筛选出终端设备频繁收听到的一个或者多个目标跟踪区，并根据这些目标跟踪区的标识信息确定出终端设备所对应的第一注册信息，可使得确定出的第一注册区信息能够更为准确的表征出终端设备的地理位置。
当上述第一消息中包含终端设备检测到上述通信触发条件之前最后一次收听到的一个或者多个第四跟踪区时，在一种可选的具体实现中，核心网设备在获取到各第一跟踪区的收听频繁指数后，可再获取预设的收听频繁指数阈值。然后，核心网设备可从上述各第一跟踪区中筛选出一个或者多个待选跟踪区。这里，上述待选跟踪区就是收听频繁指数等于或者大于上述收听频繁指数阈值的第一跟踪区。然后，终端设备可根据上述一个或者多个待选跟踪区和上述一个或者多个第四跟踪区确定出一个或者多个目标跟踪区。这里，上述一个或者多个目标跟踪区包括所有的待选跟踪区和第四跟踪区，且不存在重复的跟踪区。最后，核心网设备根据上述各第一跟踪区的标识和各第四跟踪区的标识确定出上述各目标跟踪区的标识，并根据上述各目标跟踪区的标识确定出第一注册区信息。这里，上述第一注册区信息中包括了上述各目标跟踪区的标识。
在另一种可选的具体实现中，核心网设备在获取到各第一跟踪区的收听频繁指数后，可 获取预设的收听频繁指数阈值。然后，采取如同前文上述的先根据收听频繁指数大小排序，再基于收听频繁指数的和值和收听频繁指数阈值筛选目标跟踪区的方式从上述各第一跟踪区中筛选出一个或者多个待选跟踪区。然后，终端设备可根据上述一个或者多个待选跟踪区和上述一个或者多个第四跟踪区确定出一个或者多个目标跟踪区。这里，上述一个或者多个目标跟踪区包括所有的待选跟踪区和第四跟踪区，且不存在重复的跟踪区。最后，核心网设备根据上述各第一跟踪区的标识和各第四跟踪区的标识确定出上述各目标跟踪区的标识，并根据上述各目标跟踪区的标识确定出第一注册区信息。这里，上述第一注册区信息中包括了上述各目标跟踪区的标识。
S105，核心网设备向基站发送包含有上述第一注册区信息的第二消息。

S106，基站接收并向终端设备转发上述第二消息。
在一些可行的实施方式中，基站在上述信道资源上接收到核心网设备发送的第二消息后，可通过其为终端设备配置的信道资源上将上述第一消息转发至终端设备。这里，基站发送给终端设备消息可以是未经其修改的第二消息，也可以是基站基于其与终端设备之间的通信协议修改后的第二消息(为方便理解，下文以第四消息代替描述)。可以理解到的是，上述第四消息中包含的第一注册区信息和第二消息中包含的第一注册区信息相同。
S107，终端设备接收上述第二消息，并提取出上述第一注册区信息。
在一些可行的实施方式中，终端设备在接收到上述第二消息或者第四消息后，可根据其与基站之间的通信协议对上述第二消息或者第四消息进行解析，以提取出上述第二消息或者上述第四消息所包含的第一注册区信息。
可选的，终端设备在获取到上述第一注册区信息后，可根据该第一注册区信息更新其上一次注册区信息更新得到第二注册区信息。由于上述第一注册区信息能够更准确的表征终端设备的地理位置，这样可使得更新之后终端设备所关联的注册区信息(即第一注册区信息)所指示的跟踪区与终端设备所连接的卫星通信小区所覆盖的跟踪区更加匹配，从而可以有效减少终端设备发起注册区信息更新请求的次数，避免了通信网络的通信资源的浪费。
可选的，终端设备在获取到上述第一注册区信息后，还可根据该第一注册区信息估算出终端设备的地理位置，从而快速的确定出终端设备能够建立连接的一个或则多个卫星通信邻区，提升了终端设备进行小区重选等操作效率，也进一步提升了通信网络的适用性和实用性。
在本申请实施例中，终端设备通过基站向核心网设备发送其在第一预设时段内收听到的一个或者多个第一跟踪区的收听频繁指数，然后核心网设备可基于各第一跟踪区的收听频繁指数确定出终端设备近期频繁收听到的跟踪区，并把这个跟踪区的信息形成第一注册区信息再通过基站发送给终端设备。由于核心网设备基于各第一跟踪区的收听频繁指数确定出的注册区信息的精度更高，能够更为准确的表征出终端设备的地理位置，避免了终端设备因注册区信息不准确而频繁的向核心网设备发起注册更新请求的问题，也为终端设备进行小区重选等操作提供了便利，从而减少了通信网络的通信资源的浪费，提升了通信网络的通信资源利 用率和适用性。

S105’，核心网设备向基站发送包含上述各第一跟踪区的寻呼优先级的寻呼请求消息。
在一些可行的实现方式中，核心网设备在确定出上述各第一跟踪区的寻呼优先级或者各待寻呼跟踪区的寻呼优先级之后，可根据核心网设备与基站之间的通信协议对上述各第一跟踪区的寻呼优先级或者各待寻呼跟踪区的寻呼优先级进行打包，以得到包含有各第一跟踪区的寻呼优先级或者各待寻呼跟踪区的寻呼优先级的寻呼请求消息。然后，核心网设备可通过基站为其配置的通信资源向基站发送上述寻呼请求信息。
S106’，基站接收上述寻呼请求消息，并根据各第一跟踪区的寻呼优先级对各第一跟踪区进行寻呼。
在一些可行的实现方式中，基站在接收到上述寻呼请求消息后，可根据其与核心网设备之间的通信协议对上述寻呼请求消息进行解析，以得到上述各第一跟踪区的寻呼优先级或者各待寻呼跟踪区的寻呼优先级。然后，基站可根据上述各第一跟踪区的寻呼优先级依次在各第一跟踪区所覆盖的卫星通信小区中向终端设备发起寻呼。或者，基站可根据上述各待选跟踪区的寻呼优先级依次在各待选跟踪区所覆盖的卫星通信小区中向终端设备发起寻呼。
根据终端设备提供的各第一跟踪区的收听频繁指数确定出可对终端设备进行寻呼的跟踪区以及每个可以寻呼的跟踪区的寻呼优先级，可减少在一些离终端设备较远的跟踪区中进行的无效寻呼操作，也可通过寻呼优先级提升对终端设备的寻呼速度，节省了通信网络的通信资源，提升了通信网络的适用性。
