Description

通信方法、设备及系统 技术领域
本申请涉及通信领域，尤其涉及通信方法、设备及系统。
背景技术
由于传统陆地网络(terrestrial network，TN)不能提供无缝覆盖，特别是在大海、沙漠、空中等无法部署基站的地方，因此，非陆地网络(non-terrestrial network，NTN)被引入通信系统中，NTN指将基站或者部分基站功能部署在高空平台或者卫星上为终端设备提供无缝覆盖的网络。
其中，部署在高空平台或者卫星上的基站或者部分基站功能提供的覆盖区域可以称为NTN小区。通常，NTN小区的覆盖范围较大，一个NTN小区的覆盖区域可能同时被多个TN小区覆盖，该多个TN小区可以理解为NTN相邻的TN小区，也就是说，NTN小区相邻的TN小区较多。例如图1a所示，NTN小区的全部覆盖区域同时被多个TN小区覆盖；或者，如图1b所示，NTN小区的覆盖区域中的部分区域同时被多个TN小区覆盖。在该情况下，当终端设备驻留在NTN小区时，通常希望终端设备可以及时重选到TN小区中。
然而，由于NTN小区相邻的TN小区较多，终端设备进行小区重选时需要测量大量的频点，导致终端设备的能耗较大，因此，如何降低终端设备的能耗，是目前亟待解决的问题。
发明内容
本申请实施例提供一种通信方法、设备及系统，可以降低终端设备的能耗。
为达到上述目的，本申请的实施例采用如下技术方案：
第一方面，提供了一种通信方法。该方案中，接收来自网络设备的区域配置信息，并根据区域配置信息确定第一子区域，最后根据与第一子区域对应的一个或多个相邻频点信息和/或一个或多个邻区信息进行测量。其中，区域配置信息指示多个子区域的信息，该多个子区域构成的地理区域范围包括第一小区的覆盖区域，第一子区域为该多个子区域中终端设备当前所处的一个子区域。基于该方案，由于可以根据网络设备发送的区域配置信息，从构成第一小区的多个子区域中确定当前所处的第一子区域，进而根据第一子区域对应的一个或多个相邻频点信息和/或一个或多个邻区信息进行测量，因此，可以降低的能耗，加快重选。

在一些可能的设计中，该通信方法还包括：向网络设备发送请求消息，该请求消息携带第一子区域的指示信息，该请求消息用于请求与第一子区域对应的一个或多个相邻频点信息。基于该方案，网络设备可以仅发送第一子区域对应的一个或多个相邻频点信息，而无需发送每个子区域对应的相邻频点信息，因此可以节省传输开销。
在一些可能的设计中，该指示信息用于确定以下一项或多项：第一子区域的子区域标识、第一子区域的中心位置坐标、或者第一子区域的用户可读名称。
在一些可能的设计中，该指示信息为第一前导码，该第一前导码与第一子区域对应；或者，该指示信息为第一前导码和第一接入资源，第一前导码和第一接入资源均与第一子区域对应。基于该方案，可以隐式地向网络设备请求第一子区域对应的一个或多个相邻频点信息，相比于直接发送第一子区域的标识、第一子区域的中心位置坐标信息、或者第一子区域的用户可读名称，可以节省传输开销。

具体实施方式
为了方便理解本申请实施例的技术方案，首先给出本申请相关技术的简要介绍如下。
第一、非地面通信系统(non-terrestrial network，NTN)
非地面通信系统可以包括卫星系统。按照卫星高度，即卫星轨位高度，可以将卫星系统分为高椭圆轨道(highly elliptical orbiting，HEO)、高轨(geostationary earth orbit，GEO)卫星、中轨(medium earth orbit，MEO)卫星和低轨(low-earth orbit，LEO)卫星。此外，非地面通信系统还可以包括高空平台(high altitude platform station，HAPS)通信系统。其中，GEO卫星又称静止卫星，其运动速度与地球自转速度相同，因此GEO卫星相对地面保持静止状态，对应的，GEO卫星的小区也是静止的。GEO卫星小区的覆盖较大，一般情况下小区的直径为500km。
其中，LEO卫星相对地面移动较快，大约7Km/s，因此LEO卫星提供的服务覆盖区域也随之移动。
第二、卫星小区映射方式。
卫星小区映射方式包括地面静止小区的映射方式和地面移动小区的映射方式。
其中，地面静止小区的映射方式是指小区的位置在地面是不动的，移动的卫星通过调整其波束形成这些小区。如图2a所示，T1时刻：小区1和小区2由卫星1的波束覆盖，小区3和4由卫星2的波束覆盖；T2时刻：虽然卫星1和卫星2都向左移动，但是依然可以调整自己的波束，保证小区1、小区2、小区3和小区4的覆盖；T3时刻：相比T1时刻，卫星1和卫星2已经移动了足够的距离，卫星1无法通过调整波束再为小区2提供覆盖，卫星2无法通过调整波束为小区4提供覆盖，此时，卫星2可以为小区2提供覆盖，而卫星3可以为小区4提供覆盖。
其中，地面移动小区的映射方式是指，卫星并不动态调整其波束方向，卫星覆盖的小区随着卫星的移动在地面上移动。如图2b所示，T1时刻：区域1、区域2、区域3和区域4分别由卫星1形成的小区1和小区2、以及卫星2形成的小区3和小区4进行覆盖，而在T3时刻，区域1、区域2、区域3和区域4分别由卫星1形成的小区2、卫星2形成的小区3和小区4、以及卫星3形成的小区5进行覆盖。
第三、无线资源控制(radio resource control，RRC)状态。
以新空口(new radio，NR)系统为例，在NR中，终端设备的RRC状态包括如下三种状态：RRC连接态(RRC_CONNECTED)、RRC去活动态(RRC_INACTIVE)和RRC空闲态(RRC_IDLE)，三种状态的转换如图3所示。
其中，当终端设备处于RRC连接态时，终端设备与接入网设备以及核心网设备都已经建立了连接，当有数据到达网络时可以直接传输到终端设备；当终端设备处于RRC去活动态时，终端设备和接入网设备以及核心网设备之间建立过链路，但是终端设备和接入网设备之间的链路被释放了，此时，终端设备和接入网设备保存有终端设备的上下文，当有数据需要传输时，接入网设备可以快速地恢复链路；当终端设备处于RRC 空闲态时，终端设备与接入网设备以及核心网设备之间都没有建立过链路，当有数据需要传输时，需要先建立终端设备到接入网设备以及核心网设备的链路。
可以理解的是，上述RRC状态仅为一种举例，不应对本申请构成任何限定。本申请也并不排除在未来的协议中定义其他可能的命名来替代现有命名，但具有相同或相似的特性，或者也有可能出现其他的状态。
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描述。其中，在本申请的描述中，除非另有说明，“/”表示前后关联的对象是一种“或”的关系，例如，A/B可以表示A或B；本申请中的“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，其中A,B可以是单数或者复数。并且，在本申请的描述中，除非另有说明，“至少一个”是指一个或者多个，“多个”是指两个或多于两个。“以下至少一项(个)”或其类似表达，是指的这些项中的任意组合，包括单项(个)或复数项(个)的任意组合。例如，a，b，或c中的至少一项(个)，可以表示：a，b，c，a-b，a-c，b-c，或a-b-c，其中a，b，c可以是单个，也可以是多个。另外，为了便于清楚描述本申请实施例的技术方案，在本申请的实施例中，采用了“第一”、“第二”等字样对功能和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，并且“第一”、“第二”等字样也并不限定一定不同。
本申请实施例的技术方案可以应用于各种通信系统。例如：正交频分多址(orthogonal frequency-division multiple access，OFDMA)、单载波频分多址(single carrier FDMA，SC-FDMA)、NTN系统和其它系统等。术语“系统”可以和“网络”相互替换。OFDMA系统可以实现诸如演进通用无线陆地接入(evolved universal terrestrial radio access，E-UTRA)、超级移动宽带(ultra mobile broadband，UMB)等无线技术。E-UTRA是通用移动通信系统(universal mobile telecommunications system，UMTS)演进版本。第三代合作伙伴计划(3rd generation partnership project，3GPP)在长期演进(long term evolution，LTE)和基于LTE演进的各种版本是使用E-UTRA的新版本。第五代(5thgeneration，5G)通信系统是正在研究当中的下一代通信系统。其中，5G通信系统包括非独立组网(non-standalone，NSA)的5G移动通信系统，独立组网(standalone，SA)的5G移动通信系统，或者，NSA的5G移动通信系统和SA的5G移动通信系统。此外，通信系统还可以适用于面向未来的通信技术，都适用本申请实施例提供的技术方案。上述适用本申请的通信系统仅是举例说明，适用本申请的通信系统不限于此，在此统一说明，以下不再赘述。

如图7a所示，为本申请实施例提供的一种通信方法，该通信方法包括如下步骤：
S701、网络设备确定多个子区域。其中，子区域表示实际的地理区域范围，多个子区域构成的地理区域范围包括第一小区的覆盖区域。
一种可能的实现方式中，多个子区域构成的地理区域范围与第一小区的覆盖区域相同，也就是说，第一小区的覆盖区域可以划分为多个子区域。如图7b所示，实线表示第一小区的覆盖区域，虚线表示对第一小区的覆盖区域的划分，第一小区的覆盖区域被划分为子区域1、子区域2、子区域3、和子区域4共4个子区域。需要说明的是，图7b仅是示例性的一种划分方式，实际应用中还可以有其他的划分方式。例如，将第一小区划分为多个圆形区域，本申请实施例对子区域的个数以及子区域的划分方式不 做具体限定。可以理解的是，子区域并不等同于小区，例如，图7b所示，并不能理解为第一小区被划分为4个小区，而是应该理解为第一小区的覆盖区域可以被划分为4个地理区域范围。可以理解的是，子区域也可以认为是逻辑上的子小区。
另一种可能的实现方式中，多个子区域构成的地理区域范围可能大于第一小区的覆盖区域。如图7c所示，实线构成的区域表示第一小区的覆盖区域，虚线构成的4个区域表示子区域1、子区域2、子区域3、和子区域4共4个子区域，该4个区域的区域范围大于第一小区的覆盖区域。
可选的，本申请实施例中，可以由网络设备将第一小区的覆盖区域划分为多个子区域，或者也可以由其他网元(例如操作管理维护(operation administration and maintenance，OAM)网元)对第一小区的覆盖区域进行划分，然后将多个子区域的信息发送给网络设备，本申请实施例对此不做具体限定。
可选的，本申请实施例中，在对第一小区的覆盖区域进行一次划分之后的一段时间内，终端设备均可以根据该次划分进行邻频或邻区测量。也就是说，在该段时间内，本申请实施例中的步骤S701-S702可以执行一次，本申请实施例中的下述步骤S703-S704可以执行多次。
其中，第一小区为网络设备下的一个或多个小区中的任意一个小区。
可选的，多个子区域中每个子区域的区域范围可以无重叠，也可以允许有重叠，但是一个子区域的区域范围不能完全覆盖另一个子区域的区域范围。
需要说明的是，本申请实施例中，第一小区可以是NTN小区，也可以是TN小区，本申请实施例对此不做具体限定，在此统一说明，下述实施例不再赘述。S702、网络设备向终端设备发送区域配置信息。相应的，终端设备接收来自网络设备的区域配置信息。
其中，该区域配置信息指示上述多个子区域的信息。
其中，第一小区为终端设备当前的服务小区。
可选的，网络设备可以通过广播消息向第一小区的所有终端设备发送区域配置信息；或者，可以通过单播消息向第一小区的终端设备单独发送区域配置信息；或者，可以通过组播消息向第一小区的一组终端设备发送区域配置信息，本申请实施例对此不做具体限定。
可选的，网络设备可以将区域配置信息携带在系统消息中发送，也可以携带在专用的RRC消息中发送，本申请实施例对此不做具体限定。
可选的，在本申请实施例的不同实现方式下，区域配置信息的内容也可以不同：
一种可能的实现方式中，区域配置信息可以包括多个子区域中每个子区域的中心位置坐标信息和每个子区域的区域半径信息；或者，区域配置信息可以包括每个子区域的用户可读名称；或者，区域配置信息可以包括每个子区域的中心位置坐标信息、每个子区域的区域半径信息以及每个子区域的用户可读名称。此外，区域配置信息还可以包括每个子区域的区域标识。例如，假设网络设备将第一小区划分为2个子区域，区域配置信息包括多个子区域中每个子区域的中心位置坐标信息和区域半径信息时，区域配置信息可以为{中心位置坐标1，区域半径1}，{中心位置坐标2，区域半径2}；或者，区域配置信息包括多个子区域中每个子区域的中心位置坐标信息、区域半 径信息和子区域标识时，区域配置信息可以为{子区域1，中心位置坐标1，区域半径1}，{子区域2，中心位置坐标2，区域半径2}。
可选的，区域配置信息中可以直接指示每个子区域的区域标识，例如配置信息为{子区域1，中心位置坐标1，区域半径1}；或者，也可以间接指示每个子区域的区域标识，示例性的，区域配置信息中的子区域的顺序即为子区域的区域标识，例如，{中心位置坐标1，区域半径1}为区域配置信息中的第1个子区域信息，则可以对应为子区域1，{中心位置坐标2，区域半径2}为区域配置信息中的第2个子区域信息，则可以对应为子区域2。
其中，每个子区域的中心位置坐标信息不同，每个子区域的区域半径信息可以相同也可以不同。
其中，每个子区域的用户可读名称可以反映子区域的区域范围。例如网络设备将第一小区划分为2个子区域，以第1个子区域的中心位置坐标为圆心，第1个子区域的区域半径为半径的区域范围为上海黄浦区，则该第1个子区域的用户可读名称可以为上海黄浦区；以第2个子区域的中心位置为圆心，第2个子区域的区域半径为半径的区域范围为上海徐汇区，则该第2个子区域的用户可读名称可以为上海徐汇区；或者，每个子区域的用户可读名称可以反映子区域中的某个位置。例如，第1个子区域为上海黄浦区，则第1个子区域的用户可读名称可以为上海黄浦区的某个标志性建筑名称。
需要说明的是，网络设备确定多个子区域时，可以确定每个子区域的区域范围(例如每个子区域的中心位置坐标信息和区域半径信息)，但是在区域配置信息中，可以仅携带子区域的用户可读名称。
另一种可能的实现方式中，区域配置信息可以包括多个子区域中每个子区域的长度和宽度。此外，区域配置信息还可以包括经度线方向的子区域总数和纬度线方向的子区域总数。其中，经度线方向的子区域总数为第一小区的覆盖范围对应的经度线方向的子区域总数，纬度线方向的子区域总数为第一小区的覆盖范围对应的纬度线方向的子区域总数。经度线方向的子区域总数与纬度线方向的子区域总数的乘积为上述步骤S701中构成第一小区的覆盖范围的多个子区域的个数。这种方式下，区域配置信息还可以包括每个子区域的用户可读名称。用户可读名称的描述参考前述说明，此处不再赘述。
其中，多个子区域中同一个子区域的长度和宽度可以相同也可以不同，例如，对于多个子区域中的子区域1，其长度和宽度均可以为200，或者其长度和宽度可以分别为200和100；不同子区域的长度可以相同也可以不同；不同子区域的宽度可以相同也可以不同，例如，对于多个子区域中的子区域1和子区域2，子区域1的长度和宽度可以分别为200和100，子区域2的长度和宽度可以分别为400和300；或者子区域1的长度和宽度可以分别为200和100，子区域2的长度和宽度也分别为200和100，本申请实施例对此不做具体限定。
S703、终端设备根据区域配置信息确定第一子区域。
其中，第一子区域为上述多个子区域中终端设备当前所处的一个子区域。
一种可能的实现方式中，若终端设备具有定位功能，则终端设备根据区域配置信 息确定第一子区域，可以为：终端设备获取该终端设备当前的地理位置信息，并根据终端设备当前的地理位置信息和区域配置信息确定第一子区域。
可选的，在该可能实现方式中，根据区域配置信息的不同，终端设备根据终端设备当前的地理位置信息和区域配置信息，确定第一子区域的方式也不同。示例性的，可以有如下两种方式：
方式一：区域配置信息包括多个子区域中每个子区域的中心位置坐标信息和每个子区域的区域半径信息。
在该方式一下，终端设备获取的该终端设备当前的地理位置信息可以为终端设备当前所处的地理位置的位置坐标信息。第一子区域为子区域半径小于第一直线距离的子区域，第一直线距离为该子区域半径对应的子区域中心位置坐标与终端设备当前所处的地理位置的位置坐标之间的直线距离。
示例性的，终端设备可以分别计算与每个子区域对应的直线距离，然后将与每个子区域对应的直线距离与每个子区域对应的区域半径进行比较；若与某一子区域对应的直线距离小于该子区域对应的区域半径，终端设备确定该子区域为第一子区域。其中，每个子区域对应的直线距离为终端设备当前所处的地理位置的位置坐标和每个子区域的中心位置坐标之间的直线距离。
可选的，若存在大于1个子区域对应的直线距离小于子区域对应的区域半径，则将子区域对应的直线距离与该子区域对应的区域半径之差最小的子区域，确定为第一子区域。
例如，网络设备将第一小区划分为2个子区域，区域配置信息包括{中心位置坐标1，区域半径1}，{中心位置坐标2，区域半径2}，终端设备当前所处的地理位置的位置坐标为位置坐标0，终端设备计算的中心位置坐标1和位置坐标0之间的直线距离为距离1，中心位置坐标2和位置坐标0之间的直线距离为距离2，若距离1大于区域半径1，距离2小于区域半径2，则终端设备将{中心位置坐标2，区域半径2}对应的子区域确定为第一子区域；或者，若距离1小于区域半径1，距离2大于区域半径2，则终端设备将{中心位置坐标1，区域半径1}对应的子区域确定为第一子区域。若距离1小于区域半径1，距离2也小于区域半径2，则终端设备计算距离1与区域半径1之差以及距离2与区域半径2之差，若距离1与区域半径1之差小于距离2与区域半径2之差，则终端设备将{中心位置坐标1，区域半径1}对应的子区域确定为第一子区域。

其中，第三信号质量差值为终端设备在测量时长T内第j次测量的第一邻区的信号质量，与终端设备对第一邻区进行第j次测量时第一小区的信号质量之间的差值。第四信号质量差值为终端设备在测量时长T内第j-1次测量的第一邻区的信号质量，与终端设备对第一邻区进行第j-1次测量时第一小区的信号质量之间的差值。
其中，第三信号质量差值与第四信号质量差值满足信号质量差门限值的相关说明，可参考上述情况三中的相关说明，在此不再赘述。
可以理解的是，终端设备可以在上述八种情况中任意一种情况所述的条件满足时启动定时器，也可以在上述八中情况中任意多种情况组合得到的条件满足时启动定时器，例如终端设备在情况四和情况五组合得到的条件满足时启动定时器。
基于本申请实施例提供的通信方法，由于终端设备可以根据网络设备发送的第一配置信息停止测量第一邻区/第一频点，或者降低第一邻区/第一频点的优先级，或者删除第一邻区/第一频点，在第一邻区/第一频点的质量较差或者无法测量到第一邻区/第一频点的情况下，可以减少对第一邻区/第一频点的测量次数，从而降低终端设备的能耗。
示例性的，如图8b所示，假设终端设备1处于NTN小区的覆盖范围中同时被TN小区覆盖的位置，终端设备2处于NTN小区的覆盖范围中没有同时被TN小区覆盖的位置，理论上终端设备2不需要测量NTN小区的TN邻区，但是由于邻区配置是以小区为粒度的，因此终端设备2实际也会进行TN邻区的测量，从而浪费大量能耗。
基于本申请实施例提供的通信方法，终端设备2可以根据第一配置信息，停止测量TN邻区，或者降低TN邻区的优先级，或者删除TN邻区，从而减少对TN邻区测量的次数，进而降低终端设备的能耗。
可以理解的是，上述方法可以适用于存在NTN小区的场景，但不应对本申请构成任何限定，本申请还可以适用于其他场景，例如可以适用于存在覆盖范围比较大的小区的场景。
其中，上述步骤S801至S803中的网络设备的动作可以由图5所示的网络设备30中的处理器301调用存储器302中存储的应用程序代码以指令该网络设备执行，上述步骤S801至S803中的终端设备的动作可以由图5所示的终端设备40中的处理器401调用存储器402中存储的应用程序代码以指令该网络设备执行，本实施例对此不作任何限制。
需要说明的是，本申请实施例中如图8a所示的通信方法可以单独执行，也可以在如图7a所示的通信方法的基础上执行，例如，第一配置信息可以用于去激活与第一子区域对应的一个或多个相邻频点中至少一个相邻频点的测量，当终端设备根据与第一子区域对应的一个或多个相邻频点信息进行测量时，若连续N次未测量到与第一子区域对应的一个或多个相邻频点中的一个相邻频点，则终端设备启动定时器，在该定时器的运行时间内，停止测量该一个相邻频点，或者降低该一个相邻频点的优先级，或者删除该一个相邻频点的优先级，此时，可以进一步降低终端设备的能耗。
可以理解的，本申请实施例中，终端设备和/或网络设备可以执行本申请实施例中的部分或全部步骤，这些步骤或操作仅是示例，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，各个步骤可以按照本申请实施例呈现的不同的顺序来执行，并且有可能并非要执行本申请实施例中的全部操作。
在本申请的各个实施例中，如果没有特殊说明以及逻辑冲突，不同的实施例之间的术语和/或描述具有一致性、且可以相互引用，不同的实施例中的技术特征根据其内在的逻辑关系可以组合形成新的实施例。
可以理解的是，以上各个实施例中，由终端设备实现的方法和/或步骤，也可以由可用于终端设备的部件(例如芯片或者电路)实现，由网络设备实现的方法和/或步骤，也可以由可用于网络设备的部件(例如芯片或者电路)实现。

本申请实施例可以根据上述方法实施例中对通信装置进行功能模块的划分，例如，可以对应各个功能划分各个功能模块，也可以将两个或两个以上的功能集成在一个处理模块中。上述集成的模块既可以采用硬件的形式实现，也可以采用软件功能模块的形式实现。需要说明的是，本申请实施例中对模块的划分是示意性的，仅仅为一种逻辑功能划分，实际实现时可以有另外的划分方式。
