在介绍本申请技术方案之前,先对本申请涉及的一些技术知识进行介绍说明。
非地面网络(Non-Terrestrial Network,NTN)技术
目前,相关标准组织正在研究NTN技术,NTN技术一般采用卫星通信的方式向地面用户提供通信服务。相比于地面的蜂窝通信网络,卫星通信具有很多独特的优点。首先,卫星通信不受用户地域的限制,例如一般的陆地通信不能覆盖海洋、高山、沙漠等无法搭设通信设备或由于人口稀少而不做通信覆盖的区域,而对于卫星通信来说,由于一颗卫星即可以覆盖较大的地面,加之卫星可以围绕地球做轨道运动,因此理论上地球上每一个角落都可以被卫星通信覆盖。其次,卫星通信有较大的社会价值。卫星通信在边远山区、贫穷落后的国家或地区都可以以较低的成本覆盖到,从而使这些地区的人们享受到先进的语音通信和移动互联网技术,有利于缩小与发达地区的数字鸿沟,促进这些地区的发展。再次,卫星通信距离 远,且通信距离增大通讯的成本没有明显增加;最后,卫星通信的稳定性高,不受自然灾害的限制。
通信卫星按照轨道高度的不同分为低地球轨道(LowEarth Orbit,LEO)卫星、中地球轨道(MediumEarth Orbit,MEO)卫星、地球同步轨道(Geostationary Earth Orbit,GEO)卫星、高椭圆轨道(High Elliptical Orbit,HEO)卫星等等。目前阶段主要研究的是LEO和GEO。
1、LEO
低轨道卫星高度范围为500km~1500km,相应轨道周期约为1.5小时~2小时。用户间单跳通信的信号传播延迟一般小于20ms。最大卫星可视时间20分钟。信号传播距离短,链路损耗少,对用户终端设备的发射功率要求不高。
2、GEO
地球同步轨道卫星,轨道高度为35786km,围绕地球旋转周期为24小时。用户间单跳通信的信号传播延迟一般为250ms。
为了保证卫星的覆盖以及提升整个卫星通信系统的系统容量,卫星采用多波束覆盖地面,一颗卫星可以形成几十甚至数百个波束来覆盖地面;一个卫星波束可以覆盖直径几十至上百公里的地面区域。
为了适应卫星通信场景的特点,在传统的小区切换机制的基础上,卫星通信引入了定时切换和距离切换机制:
定时切换:网络设备在切换消息中配置切换时间窗以及切换测量事件,终端设备只有在切换时间窗内且候选切换小区(候选目标小区)的测量结果满足切换测量事件才能发起切换流程。
距离切换:网络设备在切换消息中配置切换距离事件以及切换测量事件,终端设备只有在切换距离事件满足且候选切换小区的测量结果满足切换测量事件才能发起切换流程。

在图2所示架构中,接入网设备40的功能集成在卫星20上,也即卫星20具备接入网设备40的功能。终端设备10和卫星20之间可通过空口(如Uu接口)进行通信。卫星20和NTN网关30(通常位于地面)之间可通过卫星无线接口(Satellite Radio Interface,SRI)进行通信。
在图2所示架构中,以上行传输为例,终端设备10将上行信号发送给卫星20,卫星20将上述上行信号转发给NTN网关30,再由NTN网关30将上述上行信号发送给核心网设备 50。以下行传输为例,来自核心网设备50的下行信号发送给NTN网关30,NTN网关30将上述下行信号转发给卫星20,再由卫星20将上述下行信号转发给终端设备10。

以蜂窝通信网络为例,蜂窝通信网络中的接入网设备40可以是基站。基站是一种部署在接入网中用以为终端设备10提供无线通信功能的装置。基站可以包括各种形式的宏基站,微基站,中继站,接入点等等。在采用不同的无线接入技术的系统中,具备基站功能的设备的名称可能会有所不同,例如在5G NR系统中,称为gNodeB或者gNB。随着通信技术的演进,“基站”这一名称可能会变化。为方便描述,本申请实施例中,上述为终端设备10提供无线通信功能的装置统称为基站或接入网设备。
另外,本申请实施例中涉及的终端设备10,可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其它处理设备,以及各种形式的用户设备(User Equipment,UE),移动台(Mobile Station,MS),终端设备(terminal device)等等。为方便描述,本申请实施例中,上面提到的设备统称为终端设备。在本申请实施例中,有些地方使用“UE”代表“终端设备”。在本申请实施例中,“网络设备”可以是接入网设备(如基站)或者卫星。

另外,在本申请实施例中,名词“网络”和“系统”通常混用,但本领域技术人员可以理解其含义。本申请实施例描述的技术方案可以适用于长期演进(Long Term Evolution,LTE)系统,也可以适用于5G系统,也可以适用于5G NR系统后续的演进系统或者其他通信系统,本申请对此不作限定。
请参考图4,其示出了本申请一个实施例提供的优化切换过程的控制方法的流程图。本实施例以该方法应用于图1、图2或图3所示的通信系统中来举例说明。该方法可以包括如下步骤:
步骤210:终端设备向网络设备发送第一消息,第一消息包括无线链路失败报告信息和/或小区切换成功报告信息。

示例性的,第一消息中可以包括至少一次无线链路失败或至少一次切换失败的无线链路失败报告信息,和/或,至少一次小区切换成功的小区切换成功报告信息。

步骤220:网络设备接收终端设备发送的第一消息。
示例性的,网络设备根据终端设备反馈的无线链路失败报告信息和/或小区切换成功报告信息,优化终端设备的切换过程。
综上所述,本实施例提供的技术方案,终端设备记录无线链路、小区切换过程中的信息,向网络设备发送第一消息,在第一消息中携带无线链路失败报告信息、小区切换成功报告信息中的至少一种,针对新的卫星切换机制,提供了适配的优化反馈机制,从而向网络设备反馈卫星切换过程中的信息,解决卫星系统切换过程的优化问题,改善卫星通信切换过程的用户体验。
示例性的,无线链路失败报告信息包括如下14项数据项中的至少一项:
数据项1:网络设备配置给终端设备的至少一个条件切换事件对应的配置信息;
示例性的,网络设备为终端设备配置了至少一个候选目标小区,每个候选目标小区配置有至少一个条件切换事件。
条件切换事件包括如下事件类型中的任意一种:
条件A3事件:目标切换小区(候选目标小区)的测量结果比终端设备当前PCell(主小区)/PSCell(主辅小区)的测量结果高第一阈值;
条件A4事件:目标切换小区(候选目标小区)的测量结果高于第二阈值;
条件A5事件:终端设备当前PCell/PSCell的测量结果低于第三阈值,且,目标切换小区(候选目标小区)的测量结果高于第四阈值;
条件D1事件:终端设备与位置参考点1之间的距离大于第五阈值并且终端设备与位置参考点2之间的距离小于第六阈值;
条件T1事件:终端设备本地时间超过配置的时刻1但是不超过配置的时刻2。
其中,第一阈值、第二阈值、第三阈值、第四阈值、第五阈值、第六阈值、位置参考点1、位置参考点2、时刻1以及时刻2通过网络设备系统广播消息(小区系统广播消息)或者专用信令配置。
时刻2的配置格式可能有两种:第一种,以UTC(Universal Time Coordinated,协调世界时)时间直接给出,比如,年月日时分秒的形式:2021.11.25 17:43:05;第二种,根据时刻1间接给出,给出固定时长,时刻2=时刻1+固定时长,比如,时刻2为时刻1之后20秒对应的时刻,本申请对时刻2的配置格式不做限定。
条件切换事件对应的配置信息包括事件类型信息和事件类型对应的相关参数的配置信息。例如,条件切换事件对应的配置信息包括事件类型信息和事件类型对应的阈值配置信息;或, 条件切换事件对应的配置信息包括事件类型信息和事件类型对应的时刻配置信息。
在另一种实现方式下,条件切换事件对应的配置信息按照候选目标小区粒度上报,即:同时上报候选目标小区标识、针对该候选目标小区配置的事件类型信息以及事件类型对应的相关参数的配置信息,其中,候选目标小区标识通过小区全球标识(Cell Global Identifier,CGI)表示;或者,通过频点+物理小区标识(PhysicalCellIdentifier,PCI)表示。
事件类型/事件类型信息包括:条件A3事件、条件A4事件、条件A5事件、条件D1事件、条件T1事件中的任意一种。
事件类型对应的阈值配置信息与事件本身相关,不同的事件类型对应有不同的阈值配置信息。
例如,针对条件A3事件,阈值配置信息包括第一阈值;针对条件A4事件,阈值配置信息包括第二阈值;针对条件A5事件,阈值配置信息包括第三阈值和第四阈值;针对条件D1事件,阈值配置信息包括第五阈值和第六阈值。
事件类型对应的时刻配置信息与事件本身相关,不同的事件类型对应有不同的时刻配置信息。
例如,针对条件T1事件配置的时刻1以及时刻2。
数据项2:切换失败或者无线链路失败时,满足条件的条件切换事件对应的配置信息;
数据项3:切换失败或者无线链路失败时,满足条件的条件切换事件对应的标识信息;
数据项4:切换失败或者无线链路失败时,不满足条件的条件切换事件对应的配置信息;
数据项5:切换失败或者无线链路失败时,不满足条件的条件切换事件对应的标识信息;
针对上述的数据项2至数据项5:
示例性的,针对一个候选目标小区,网络设备可以在切换配置消息中为终端设备同时配置多个条件切换事件。例如,同时配置条件A4事件和条件D1事件;或,同时配置条件A4事件和条件T1事件;或,同时配置条件A4事件、条件D1事件和条件T1事件。
当针对一个候选目标小区配置有至少两个条件切换事件时,终端设备在同时满足全部条件切换事件后才能执行切换,向该候选目标小区(目标切换小区)发起连接建立过程。由于每一种条件切换事件独立评估,则会出现针对一个候选目标小区配置的至少两种条件切换事件条件触发不同步的问题,甚至在终端设备发生切换失败或无线链路失败时,有的条件切换事件满足了条件,有的条件切换事件不满足条件,因而出现了数据项2至数据项5不同的记录数据。
终端设备切换失败或者无线链路失败时,候选目标小区(目标切换小区)对应的条件切换事件中,满足条件的条件切换事件对应的配置信息;终端设备切换失败或者无线链路失败时,候选目标小区(目标切换小区)对应的条件切换事件中,满足条件的条件切换事件对应的标识信息;终端设备切换失败或者无线链路失败时,候选目标小区(目标切换小区)对应的条件切换事件中,不满足条件的条件切换事件对应的配置信息;终端设备切换失败或者无线链路失败时,候选目标小区(目标切换小区)对应的条件切换事件中,不满足条件的条件切换事件对应的标识信息。
条件切换事件对应的标识信息包括:条件A3事件、条件A4事件、条件A5事件、条件D1事件、条件T1事件中的任意一种。
数据项6:在针对一个候选目标小区配置有至少两个条件切换事件的情况下,从至少两个条件切换事件中的第一个条件切换事件满足到最后一个条件切换事件满足经历的时长信息;
第一条件切换事件为条件A3事件、条件A4事件、条件A5事件、条件D1事件、条件T1事件中的任意一种。最后一个条件切换事件为条件A3事件、条件A4事件、条件A5事件、条件D1事件、条件T1事件中的任意一种。
当网络设备为一个候选目标小区配置了多个条件切换事件时,在针对一个候选目标小区 配置的至少一个条件切换事件中,在时序上第一个满足条件的条件切换事件即为第一个条件切换事件;在时序上最后一个满足条件的条件切换事件即为最后一个条件切换事件。
例如,针对候选目标小区1,网络设备配置了两个条件切换事件:条件T1事件和条件A4事件,若条件A4事件首先满足条件,则条件A4事件即为第一个条件切换事件,过了一段t1时间,条件T1事件满足条件,则条件T1事件即为最后一个条件切换事件,从第一个条件切换事件满足到最后一个条件切换事件满足经历的时长信息即为t1。再如,针对候选目标小区2,网络设备配合了三个条件切换事件:条件D1事件、条件T1事件和条件A4事件,若条件D1事件首先满足条件,则条件D1事件为第一个条件切换事件,过了一段t2时间,条件T1事件满足条件,则条件T1事件为第二个条件切换事件,接着又过了t3时长,条件A4事件满足条件,则A4事件为最后一个条件切换事件,从第一个条件切换事件满足到最后一个条件切换事件满足经历的时长信息为t2+t3。
数据项7:第一个条件切换事件满足时小区的测量结果;
第一条件切换事件为条件A3事件、条件A4事件、条件A5事件、条件D1事件、条件T1事件中的任意一种。
在针对一个候选目标小区配置的至少一个条件切换事件中,在时序上第一个满足条件的条件切换事件即为第一个条件切换事件。
数据项8:切换失败或者无线链路失败时小区的测量结果;
数据项9:切换类型指示信息;
切换类型指示信息包括如下信息中的任意一种:
指示卫星切换;
指示卫星条件切换;
指示条件D1事件参与的卫星条件切换;
指示条件T1事件参与的卫星条件切换;

切换类型指示信息用于指示终端设备所执行的切换的切换类型。切换类型包括:卫星切换;卫星条件切换;条件D1事件参与的卫星条件切换;条件T1事件参与的卫星条件切换;测量结果触发的卫星条件切换,中的至少一种。
卫星条件切换为在满足条件切换事件后执行的卫星切换。
条件D1事件参与的卫星条件切换:为有条件D1事件参与的卫星条件切换,即,目标切换小区(候选目标小区)的条件切换事件中包括条件D1事件。
由于条件D1事件与其他条件切换事件(例如,条件A3事件、条件A4事件、条件A5事件)可能联合触发条件切换,因而使用“条件D1事件参与的卫星条件切换”来表示只有条件D1事件触发的卫星条件切换,或者,表示条件D1事件与其他条件切换事件联合触发的卫星条件切换。
条件T1事件参与的卫星条件切换:为有条件T1事件参与的卫星条件切换,即,目标切换小区(候选目标小区)的条件切换事件中包括条件T1事件。
由于条件T1事件与其他条件切换事件(例如,条件A3事件、条件A4事件、条件A5事件)可能联合触发条件切换,因而使用“条件T1事件参与的卫星条件切换”来表示只有条件T1事件触发的卫星条件切换,或者,表示条件T1事件与其他条件切换事件联合触发的卫星条件切换。
测量结果触发的卫星条件切换:为有条件A3事件、条件A4事件或条件A5事件参与的卫星条件切换,即,目标切换小区(候选目标小区)的条件切换事件中包括条件A3事件、条件A4事件、条件A5事件中的至少一个。
测量结果触发的卫星条件切换即:条件A3事件或条件A4事件或条件A5事件触发的卫星条件切换。
数据项10:切换失败或者无线链路失败原因值信息;
切换失败或者无线链路失败原因值信息包括:
终端设备失去网络信号覆盖;
或,终端设备评估的条件切换事件无法全部满足。
一种实现方式下,若终端设备记录多次切换失败或者无线链路失败数据,则对每次切换失败或者无线链路失败的原因值单独记录。
数据项11:预设时长内,终端设备经历切换失败或者无线链路失败的总次数;
数据项12:预设时长内,终端设备经历切换失败的次数;
数据项13:预设时长内,终端设备经历无线链路失败的次数;
针对数据项11至数据项13:
在一种实现方式下,在预设时长内,终端设备记录经历切换失败或者无线链路失败的总次数,在这种方式下,终端设备不用区分切换失败或者无线链路失败两种场景,只需要记录二者发生的总和次数。
在另一种实现方式下,在预设时长内,终端设备记录切换失败的次数和/或无线链路失败的次数。这样网络设备可以知道切换失败或者无线链路失败分别发生的次数,便于分场景优化。
当然终端设备在同时记录切换失败的次数以及无线链路失败的次数时,可能有两种记录方式:
方式1:只分别记录切换失败的次数以及无线链路失败的次数,不记录每次失败发生时间的先后顺序信息,比如:1小时内,切换失败发生3次,无线链路失败发生2次;
方式2:终端设备既要记录切换失败的次数以及无线链路失败的次数,也要记录每次失败发生时间的先后顺序信息,比如:1小时内,第一次发生切换失败,第二次发生切换失败,第三次发生无线链路失败,第四次发生切换失败,第五次发生无线链路失败。
预设时长通过如下任意一种方式配置:通过预配置方式配置、通过小区系统广播消息配置或通过专用信令配置。
数据项14:切换失败或者无线链路失败时终端设备的位置信息。
示例性的,切换成功报告信息包括如下6项数据项中的至少一项:
数据项15:网络设备配置给终端设备的至少一个条件切换事件对应的配置信息;
数据项15可以参照上述对数据项1的解释。
数据项16:在针对一个候选目标小区配置有至少两个条件切换事件的情况下,从至少两个条件切换时间中的第一个条件切换事件满足到最后一个条件切换事件满足经历的时长信息;
数据项16可以参照上述对数据项6的解释。
数据项17:全部条件切换事件满足时或者终端设备执行条件切换时对应的时刻信息;
数据项18:全部条件切换事件满足时或者终端设备执行条件切换时对应的时间比例信息;
数据项19:全部条件切换事件满足时或者终端设备执行条件切换时小区的测量结果;
针对数据项17至数据项19:
全部条件切换事件是指网络设备针对一个候选目标小区所配置的全部的条件切换事件(一个或多个)。
全部条件切换事件满足时或者终端设备执行条件切换时,是指:针对一个候选目标小区所配置的至少一个条件切换事件全部满足条件的时刻,或,终端设备执行向该候选目标小区(目标切换小区)切换的条件切换的时刻。
一种实现方式下,时刻信息可以为UTC格式定义的时刻。
时间比例信息是:在全部条件切换事件中包括条件T1事件时,其他条件切换事件的条件 满足时刻在条件T1事件的时间窗口(时刻1到时刻2)中的比例。该比例可以为实际计算结果,也可以为实际计算结果所对应的区间的取值。
例如,条件切换事件包括条件T1事件(事件满足条件为当前时刻处于时刻T1到时刻T2之间)和条件A4事件,如果条件A4事件在T1时刻到T2时刻之间的T3时刻满足,则T3时刻称为全部条件切换事件满足时或者终端设备执行条件切换时,而时间比例信息等于(T3-T1)/(T2-T1)计算出来的百分比数。
或者,预定义几个取值,比如{0.2,0.4,0.6,0.8,1},如果(T3-T1)/(T2-T1)计算结果小于0.2,则终端设备上报数字0.2,如果(T3-T1)/(T2-T1)计算结果小于0.4但大于等于0.2,则终端设备上报数字0.4,依次类推,这种方法可以节省上报比特数。
数据项20:切换成功时终端设备的位置信息。
针对上述20个数据项中提及小区测量结果的数据项:
小区的测量结果包括服务小区的测量结果和/或至少一个邻小区的测量结果。测量结果包括RSRP(Reference Signal Received Power,参考信号接收功率)、RSRQ(Reference Signal Received Quality,参考信号接收质量)、SINR(Signal to Interference plus Noise Ratio,信干噪比)类型测量结果中的至少一种。

示例性的,能力指示信息与数据项的映射关系为一对一、一对多或一对全部数据项。即,一个能力指示信息指示终端设备是否支持收集或记录一项数据项,则对于多个数据项,终端设备可以发送多个能力指示信息进行指示。或,一个能力指示信息指示终端设备是否支持收集或记录多项数据项,则对于一组数据项,终端设备可以发送一个能力指示信息进行指示,对于多组数据项,终端设备可以发送多个能力指示信息分别进行指示。或,一个能力指示信息指示终端设备是否支持收集或记录全部数据项。
一种实现方式下,第一消息所记录的全部数据项共用一个能力指示信息,只要终端设备支持该能力,则终端设备可以记录第一消息包含的任意数据项;在另一种实现方式下,第一消息所记录的部分或者全部数据项分别对应独立的能力指示信息,只有在对应数据项的能力指示信息指示允许前提下,终端设备才能记录对应项数据。

示例性的,数据收集指示信息是根据能力指示信息确定的。
示例性的,数据收集指示信息与数据项的映射关系为一对一、一对多或一对全部数据项。即,一个数据收集指示信息指示终端设备是否记录一项数据项,则对于多个数据项,网络设备可以发送多个数据收集指示信息进行指示。或,一个数据收集指示信息指示终端设备是否记录多项数据项,则对于一组数据项,网络设备可以发送一个数据收集指示信息进行指示, 对于多组数据项,网络设备可以发送多个数据收集指示信息分别进行指示。或,一个数据收集指示信息指示终端设备是否记录全部数据项。
示例性的,数据收集指示信息用于指示第一消息中所需要包含的数据项。一种实现方式下,第一消息所记录的全部数据项共用一个数据收集指示信息;在另一种实现方式下,第一消息所记录的部分或者全部数据项分别有独立的数据收集指示信息,用于控制单个数据项的收集与否。
步骤203:终端设备向网络设备发送第二消息,第二消息包括无线链路失败报告可取指示信息和/或小区切换成功报告可取指示信息。

第二消息用于告知网络设备无线链路失败报告和/或小区切换成功报告可取。
步骤204:网络设备向终端设备发送第二消息响应消息,第二消息响应消息包括上报无线链路失败报告的指示信息和/或上报小区切换成功报告的指示信息。
