相关申请的交叉引用

技术领域
本申请实施例涉及移动通信技术领域，尤其涉及一种信息上报方法、终端、网络设备、存储介质及计算机程序产品。
背景技术
非地面网络(Non-Terrestrial Networks，NTN)也叫卫星通信系统，是指地面上的无线电通信设备利用卫星作为中继而进行的通信，卫星通信系统由卫星部分和地面部分组成，如图1所示。卫星通信的特点是通信范围大，只要在卫星发射的电波所覆盖的范围内，任何两点之间都可进行通信，且不易受陆地灾害的影响。
目前，NTN采用条件切换(Condition Handover，CHO)提升小区切换的稳健性，CHO是指网络侧给终端配置CHO触发条件和相应的目标小区，当CHO触发条件满足时由终端触发CHO，执行小区切换。然而，如果CHO触发条件的配置不合理，可能会导致过早或过晚切换，造成切换失败或切换后随即发生无线链路失败(Radio Link Failure，RLF)，影响切换的稳健性和可靠性。

具体实施方式
为了使本申请的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本申请进行进一步详细说明。应当理解，此处描述的具体实施例仅仅用以解释本申请，并不用于限定本申请。
下面将通过实施例并结合附图具体地对本申请的技术方案以及本申请的技术方案如何解决上述技术问题进行详细说明。下面的实施例可以相互结合，对于相同或相似的概念或过程可能在某些实施例中不再赘述。
另外，本申请实施例所记载的技术方案之间，在不冲突的情况下，可以任意组合。
本申请实施例提供了一种信息上报方法，应用于终端。图2为本申请实施例提供的一种信息上报方法的流程示意图一。如图2所示，在本申请的实施例中，应用于终端的信息上报方法主要包括以下步骤：
S101、向网络设备上报第一报告和/或第二报告；其中，第一报告用于指示CHO成功的相关信息，第二报告用于指示CHO失败的相关信息。
在本申请的实施例中，终端可以向网络设备上报第一报告和/或第二报告；第一报告用于指示条件切换CHO成功的相关信息，第二报告用于指示条件切换CHO失败的相关信息。
需要说明的是，在本申请的实施例中，CHO成功指的是CHO切换成功，CHO失败指的是CHO切换失败。
在本申请的实施例中，终端可以在CHO成功但濒临失败的场景下，向网络设备上报第一报告，也可以在CHO失败的场景下，向网络设备上报第二报告，覆盖场景全面，有助于实现NTN系统中CHO配置调整和/或优化，从而有效避免可能出现的切换失败或RLF的情况。
需要说明的是，在本申请的实施例中，第一报告和/或第二报告，可以是终端接收到网络设备发送的请求终端上报相关信息的请求消息后，向网络设备上报，也可以是终端主动向网络设备上报，还可以是终端向网络设备发送通知消息，通知网络设备终端存储了相关信息，并在接收到网络设备发送的请求消息后，再向网络设备上报，本申请实施例不作限定。
需要说明的是，在本申请的实施例中，第一报告和/或第二报告，终端可以直接向网络设备上报，也可以是通过其他节点转发至网络设备，该网络设备可以是CHO中的源节点，或者可以称为为终端配置CHO触发条件的节点。
示例性的，第一报告可以复用现有的终端完成小区切换时生成的成功切换报告(Successful Handover Report，SHR)，也可以新增信令用于上报。如果复用现有的SHR，可以在SHR中新增元素或在现有的扩展字段中，通过显示方式表明该SHR是第一报告，或者通过隐式方式，例如新增触发生成第一报告的原因，表明该SHR是第一报告。
示例性的，第二报告可以复用现有RLF报告，也可以新增信令用于上报。如果复用现有的RLF报告，可以新增元素或在现有的扩展字段中，通过显示方式或者通过隐式方式表明该报告是第二报告。
需要说明的是，在本申请的实施例中，终端在满足所有CHO触发条件的情况下，才会进一步执行CHO，触发条件可以是基于测量的CHO触发条件、基于位置的CHO触发条件，以及基于时间的CHO触发条件，并且，可以单独配置基于测量的CHO触发条件，但是，在配置基于位置的CHO触发条件，或者基于时间的CHO触发条件的情况下，需要一起配置基于测量的CHO触发条件。
在本申请的实施例中，基于时间的CHO触发条件触发CHO，且CHO成功，终端可以针对基于时间的CHO触发条件，新增时间阈值作为终端生成第一报告的条件，具体的，终端可以执行以下步骤：针对基于时间的CHO触发条件，若配置的允许执行CHO的起始时刻至执行CHO的时刻或应用CHO配置的时刻之间的时间间隔，大于或等于第一时间阈值，或者，小于或等于第二时间阈值，生成第一报告。
可以理解的是，在本申请的实施例中，终端可以同时监测上述时间间隔是否大于或等于第一时间阈值，以及是否小于或等于第二时间阈值，也可以只监测其中一项，决策是否生成第一报告，具体可以根据实际需求选择和设定，本申请实施例不作限定。
需要说明的是，在本申请的实施例中，若上述时间间隔小于第一时间阈值，终端不生成第一报告，当然，若上述时间间隔大于第二时间阈值，终端也不生成第一报告。
可以理解的是，在本申请的实施例中，第一时间阈值、第二时间阈值适用于基于时间的CHO触发条件，即终端需要在一定时间范围[t1,t2]内触发CHO。其中，增加第一时间阈值的作用是用于发现终端执行CHO的时刻过晚，可能存在终端无法在t2时刻之间完成CHO导致切换失败，有助于网络设备调整t2时刻配置从而降低CHO失败的风险，增加第二时间阈值的作用是用于发现终端执行CHO的时刻过早，如果t1时刻配置过晚，可能存在终端在触发CHO之前发生RLF的风险，有助于网络调整t1时刻配置从而降低RLF的风险。
需要说明的是，在本申请的实施例中，第一时间阈值、第二时间阈值可以由网络设备预先配置并发送给终端或者在协议中定义，具体的，第一时间阈值、第二时间阈值可以采用以下任一形式表示：
时长的绝对值，单位可以是ms；例如，第一时间阈值取值为100ms，表示t1时刻之后的100ms，即t1+100ms；
比例形式，例如，第一时间阈值取值为80％，表示t1时刻之后的Duration×80％，即t1+Duration×80％；其中，t1和Duration在基于时间的CHO触发条件中，由网络配置并发给终端，Duration表示允许触发CHO的持续时长。
可以理解的是，在本申请的实施例中，第一时间阈值和第二时间阈值可以是时长的绝对值，在此情况下，可以将上述时间间隔直接与第一时间阈值和第二时间阈值进行比较，当然，第一时间阈值和第二时间阈值也可以是比例形式，在此情况下，需要将上述时间间隔转化为与时间阈值同一维度上的信息，计算上述时间间隔与Duration的比值，上述时间间隔大于或等于第一时间阈值，即该比值大于或等于第一时间阈值，相应的，上述时间间隔小于或等于第二时间阈值，即该比值小于或等于第二时间阈值。
在本申请的实施例中，基于位置的CHO触发条件触发CHO，且CHO成功，终端可以针对基于位置的CHO触发条件，新增距离阈值作为终端生成第一报告的条件，具体的，终端可以执行以下步骤：针对基于位置的CHO触发条件，若CHO执行时或者应用CHO配置时，终端与服务小区参考点之间的距离大于或等于第一距离阈值，生成第一报告。
需要说明的是，在本申请的实施例中，若上述距离小于第一距离阈值，终端不生成第一报告。
可以理解的是，在本申请的实施例中，第一距离阈值适用于基于位置的CHO触发条件。其中，新增第一距离阈值的作用是用于发现终端在达到基于位置的CHO触发条件配置的与服务小区参考点之间的距离门限并持续达到CHO触发时间(time to Trigger)后，终端实际执行CHO的位置已经位于小区边缘，可能存在终端在执行CHO之前发生RLF的风险，有助于网络设备调整和/或优化基于位置的CHO触发条件配置的距离门限和CHO触发时间。
需要说明的是，在本申请的实施例中，第一距离阈值可以由网络设备预先配置并发送给终端或者在协议中定义，具体的，第一距离阈值可以采用以下任一形式表示：
距离的绝对值，单位可以是m或km；例如，第一距离阈值取值为1000m，表示与服务小区参考点之间的距离为1000m；
比例形式，例如，第一距离阈值取值为120％，表示距离基准阈值×120％，即与服务小区参考位置之间的距离为距离基准阈值×120％；或第一距离阈值取值为20％，表示距离基准阈值×(1+20％)。
可以理解的是，在本申请的实施例中，第一距离阈值可以是距离的绝对值，在此情况下，可以将上述距离直接与第一距离阈值进行比较，当然，第一距离阈值也可以是比例形式，在此情况下，需要将上述距离转化为与第一距离阈值同一维度上的信息，计算上述距离与距离基准阈值的比值，从而进行比较。
在本申请的实施例中，第一报告包含以下其中至少一项：
CHO的执行时刻，或者，CHO的执行时刻与满足最后一个CHO触发条件的时刻之间的时间间隔；
针对基于位置的CHO触发条件，满足CHO触发条件时终端与服务小区参考点之间的距离，和/或，终端与目标小区参考点之间的距离；
针对基于位置的CHO触发条件，满足CHO触发条件的时长达到配置的CHO触发时间时，终端与服务小区参考点之间的距离，和/或，终端与目标小区参考点之间的距离；
满足第一个CHO触发条件的时刻；
满足第二个CHO触发条件的时刻，或者，满足第一个CHO触发条件和第二个CHO触发条件之间的时间间隔；
触发生成第一报告的原因；
服务小区测量结果；
目标小区测量结果；
邻小区测量结果；
终端的位置信息；
终端的小区无线网络临时标识C-RNTI。
需要说明的是，在本申请的实施例中，第一报告可以包括CHO的执行时刻，或者，CHO的执行时刻与满足最后一个CHO触发条件的时刻之间的时间间隔，其中，终端在满足所有CHO触发条件的情况下，才会进一步执行CHO，当网络设备为终端配置一个CHO触发条件的情况下，这一CHO触发条件即最后一个CHO触发条件，当网络设备为终端配置两个CHO触发条件的情况下，最后一个CHO触发条件即第二个满足的CHO触发条件。CHO的执行时刻，或者，CHO的执行时刻与满足最后一个CHO触发条件的时刻之间的时间间隔，可辅助网络设备调整和/或优化上述t1时刻和t2时刻。
需要说明的是，在本申请的实施例中，满足第一个CHO触发条件的时刻，可以采用协调世界时(Universal Time Coordinated，UTC)表示，该项信息可以辅助网络设备调整优化和/或上述t1时刻和t2时刻。
需要说明的是，在本申请的实施例中，当配置两个CHO触发条件的情况下，满足第二个CHO触发条件的时刻，或者，满足第一个CHO触发条件和第二个CHO触发条件之间的时间间隔，可辅助网络设备调整和/或优化上述t1时刻和t2时刻。
需要说明的是，在本申请的实施例中，针对基于位置的CHO触发条件，满足CHO触发条件时终端与服务小区参考点之间的距离，和/或，终端与目标小区参考点之间的距离，可辅助网络设备调整和/或优化基于位置的CHO触发条件配置的距离门限。
需要说明的是，在本申请的实施例中，针对基于位置的CHO触发条件，满足CHO触发条件的时长达到配置的CHO触发时间时，终端与服务小区参考点之间的距离，和/或，终端与目标小区参考点之间的距离，可辅助网络调整和/或优化基于位置的CHO触发条件配置的距离门限和CHO触发时间。
需要说明的是，在本申请的实施例中，触发生成所述第一报告的原因，例如，使用4bit分别对应第一时间阈值、第二时间阈值、第一距离阈值，以及基于测量触发，其中，被置为1的bit所对应的原因表示触发生成第一报告的原因。
需要说明的是，在本申请的实施例中，服务小区测量结果，例如参考信号接收功率(Reference Signal Receiving Power，RSRP)/参考信号接收质量(Reference Signal Receiving Quality，RSRQ)/信号与干扰加噪声比(Signal to Interference plus Noise Ratio，SINR)；目标小区测量结果，例如RSRP/RSRQ/SINR；邻小区测量结果，例如RSRP/RSRQ/SINR；终端的小区无线网络临时标识(Cell Radio Network Temporary Identifier，C-RNTI)，例如目标C-RNTI或源C-RNTI。
在本申请的实施例中，针对CHO失败的场景下，终端可以向网络设备上报第二报告，CHO失败可能是由于终端发生过早切换、过晚切换或错误小区切换导致的，其中，过早切换是指终端发生CHO失败或在CHO成功后随即发生RLF，终端试图重建的小区是仍然是源小区，即CHO触发条件过早满足；过晚切换是指终端发生RLF后，终端试图重建的小区是目标小区，即CHO触发条件还没有满足就发生了RLF；错误小区切换是指终端发生失败后发现合适终端进入的小区是除源小区和目标小区之外的小区，即合适小区不在源小区和选择的目标小区中。
在本申请的实施例中，第二报告包含以下其中至少一项：
满足CHO触发条件的顺序和/或时刻；
针对基于位置的CHO触发条件，终端与服务小区参考点之间的距离，和/或，终端与目标小区参考点之间的距离；
CHO失败之后，终端尝试连接的小区对应的小区标识；
CHO触发条件的类型。
需要说明的是，在本申请的实施例中，满足CHO触发条件的顺序和/或时刻，具体的，如果只配置一个CHO触发条件，则记录满足该触发条件的时刻，如果该字段为空，则表明CHO触发条件未满足；如果配置两个CHO触发条件，则按时间顺序记录两个CHO触发条件分别满足的时刻，如果该字段为空，则表明两个CHO触发条件均未满足，如果该字段只记录满足一个CHO触发条件的时刻，则表明另一个CHO触发条件未满足；如果配置两个CHO触发条件，还可以记录满足第一个CHO触发条件的时刻，以及满足第二个CHO触发条件的时刻与满足第一个CHO触发条件之间的时间间隔，如果该字段为空，则表明两个CHO触发条件均未满足，如果该字段只记录满足一个CHO触发条件的时刻，则表明另一个CHO触发条件未满足。
需要说明的是，在本申请的实施例中，针对基于位置的CHO触发条件，终端与服务小区参考点之间的距离，和/或，终端与目标小区参考点之间的距离，指的是切换失败或RLF或触发执行CHO时，终端与服务小区参考点之间的距离，和/或，终端与目标小区参考点之间的距离。
需要说明的是，在本申请的实施例中，CHO触发条件的类型，例如，使用3bit分别对应基于测量的CHO触发、基于位置的CHO触发、基于时间的CHO触发；其中，基于测量的CHO触发是指终端只配置了基于测量的CHO触发条件；基于位置的CHO触发是指终端配置了基于位置的和基于测量的CHO触发条件；基于时间的CHO触发是指终端配置了基于时间的和基于测量的CHO触发条件。
在本申请的实施例中，第一，终端可以在CHO成功和失败时向网络设备上报相关的报告，覆盖场景全面，有助于实现NTN系统中CHO配置调整和/或优化，从而有效避免可能出现的切换失败或RLF的情况；第二，充分考虑NTN系统的特殊性，不仅存在传统的基于测量的CHO触发条件，还存在基于时间或基于位置的CHO触发条件，第一报告的生成、以及第一报告和第二报告的信息均针对基于时间或基于位置的CHO触发条件分别定义，使得网络设备能够针对性对CHO配置优化；第三，新增第一时间阈值和/或第二时间阈值作为终端生成第一报告的条件，可以有效避免过早或过晚触发CHO，从而提高CHO稳健性和成功率；第四，新增第一距离阈值作为终端生成第一报告的触发条件，可以有效避免与参考点的距离或CHO触发时间配置不合理导致的终端触发CHO过晚，在CHO之前发生无RLF的情况，保障用户体验的稳定性。

在本申请的实施例中，第二报告包含以下其中至少一项：
满足CHO触发条件的顺序和/或时刻；
针对基于位置的CHO触发条件，终端与服务小区参考点之间的距离，和/或，终端与目标小区参考点之间的距离；
CHO失败之后，终端尝试接入的小区对应的小区标识；
CHO触发条件的类型。
需要说明的是，在本申请的实施例中第一报告和第二报告各自包含的信息与上述终端侧方法中相关内容一致，在此不再赘述。
在本申请的实施例中，网络设备可以基于第一报告和/或第二报告进行分析，进行CHO配置调整和/或优化。
在本申请的实施例中，网络设备基于第一报告进行分析，进行CHO配置调整和/或优化，包含以下其中至少一项：
若第一报告中触发生成第一报告的原因表征终端过晚或过早执行CHO，调整和/或优化CHO触发条件；
基于第一报告中服务小区测量结果、目标小区测量结果、邻小区测量结果和终端的位置信息，调整和/或优化目标小区的选择。
需要说明的是，在本申请的实施例中，若基于第一时间阈值触发生成第一报告，即触发生成第一报告的原因表征终端过晚执行CHO，可以根据第一报告中执行CHO的时刻或者执行CHO的时刻与满足最后一个CHO触发条件的时刻之间的时间间隔，增大CHO触发条件中配置的允许触发CHO时间的持续时长，或者，根据第一报告中满足第一个CHO触发条件的时刻或满足第二个CHO触发条件的时刻或满足第二个CHO触发条件的时刻与满足第一个CHO触发条件的时刻之间的时间间隔，延后上述t1时刻，即将执行CHO的时间范围整体后移，其中，该情况下的触发条件指基于时间的CHO触发条件。
需要说明的是，在本申请的实施例中，若基于第一距离阈值触发生成第一报告，即触发生成第一报告的原因表征终端过晚执行CHO，实际上也说明终端位置靠小区边缘，可以根据第一报告中的终端满足CHO触发条件和测量事件时与服务小区参考点之间的距离，以及终端满足CHO触发条件的时长达到配置的CHO触发时间时，终端与服务小区参考点之间的距离，计算得到终端在CHO触发时间内的移动距离，如果移动距离偏大，可以缩短CHO触发条件中配置的CHO触发时间，或者缩短CHO触发条件中配置的距离基准阈值，和/或，增加新的距离基准阈值，其中，该情况下的CHO触发条件指基于位置的CHO触发条件。
需要说明的是，在本申请的实施例中，若基于第二时间阈值触发生成第一报告，即触发生成第一报告的原因表征终端过早触发CHO，可以根据第一报告中的CHO的执行时刻或者CHO的执行时刻与满足最后一个CHO触发条件的时刻之间的时间间隔，将CHO触发条件中配置的t1时刻提前，特别是在时间间隔较大时，说明t1时刻配置靠后，需要将t1时刻提前，其中，该情况下的触发条件指基于时间的CHO触发条件。
在本申请的实施例中，第二报告包含CHO失败之后，尝试接入的小区对应的小区标识，基于第二报告进行分析，进行CHO配置调整和/或优化，包含以下其中至少一项：
若小区标识与源小区或目标小区对应，调整和/或优化CHO触发条件；
若小区标识与目标小区和源小区不同的小区对应，调整和/或优化目标小区的选择。
需要说明的是，在本申请的实施例中，CHO失败之后，终端尝试接入的小区是源小区，则表示终端过早切换。网络设备可以根据第二报告中满足CHO触发条件的时刻，考虑提高CHO触发条件配置的门限取值；针对基于位置的CHO触发条件，还可以增加配置的距离基准阈值，具体的取值需要根据第二报告中终端与服务小区参考点之间的距离，和/或，终端与目标小区参考点之间的距离，综合判断确定；针对基于时间的CHO触发条件，还可以将配置的t1时刻延后，具体取值根据满足CHO触发条件的时刻确定。
需要说明的是，在本申请的实施例中，CHO失败之后，终端尝试接入的小区是目标小区，则表示终端过晚切换。网络设备可以根据第二报告中满足CHO触发条件时刻或者没有满足的CHO触发条件，考虑适当降低配置的门限取值；针对基于位置的CHO触发条件，还可以减小配置的距离基准阈值；针对基于时间的CHO触发条件，还可以将配置的t1时刻提前，具体取值根据CHO触发条件满足的时刻确定。
需要说明的是，在本申请的实施例中，CHO失败之后，终端尝试接入的小区是源小区和目标小区之外的小区，则表示终端执行错误小区的切换，网络设备可以优化目标小区的选择，其中，第二报告也可以如上述第一报告一样，包含服务小区测量结果、目标小区测量结果、邻小区测量结果和终端的位置信息，用于优化目标小区的选择，当然，也可以基于其他信息或规则优化目标小区的选择，本申请实施例不作限定。
