Description

一种信息处理方法、装置及可读存储介质
本申请要求于2022年08月10日提交中国专利局、申请号为202210954153.4、申请名称为“一种信息处理方法、装置及可读存储介质”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，尤其涉及一种信息处理方法、装置及可读存储介质。
背景技术
为了减少切换中断时间，提高切换可靠性，引入了条件切换(Conditional Handover，CHO)的机制。在CHO机制中，网络设备根据终端上报的测量报告，提前为终端配置候选的切换目标小区及执行判决条件。当终端的测量结果满足条件切换判决条件时，终端根据网络设备的配置，利用预留的目标小区资源自行发起切换，从而提高了切换成功率。
相关技术中对于CHO相关失败的参数上报和优化均是针对CHO配置的。随着技术的发展，有可能支持在CHO配置中配置辅小区组(Secondary Cell Group，SCG)配置。因此，对于CHO配置中配置有SCG配置的场景，需要提供针对切换失败的优化方案。

具体实施方式
本申请实施例中术语“和或或”，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。字符“或”一般表示前后关联对象是一种“或”的关系。
本申请实施例中术语“多个”是指两个或两个以上，其它量词与之类似。
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，显然，所描述的实施例仅仅是本申请一部分实施例，并不是全部的实施例。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他实施例，都属于本申请保护的范围。
相关技术讨论了对于CHO配置的移动鲁棒性(Mobility Robust Optimization，MRO)优化，该CHO配置中不包括SCG配置。当终端被配置了CHO配置，如果CHO执行条件满足但执行CHO发生切换失败，或者在CHO执行条件没有满足之前，终端在源小区发生了RLF，终端将在RLF报告(RLF report)中记录一些CHO相关的配置参数以及定时器(timer)，如配置的CHO候选小区，配置的CHO执行条件，从终端收到最新的CHO配置到CHO执行的时间间隔，从终端收到最新的CHO配置到在源小区发生RLF的时间间隔等。终端在上行完成消息中发送可获得(available)指示给网络设备，通知终端存储有RLF report。网络设备通过UE信息请求(UE information  request)消息向终端请求上报RLF report，终端发送UE信息响应(UE information response)消息来发送RLF report给网络设备。
但是，如背景技术所描述的，对于CHO配置信息中配置有SCG配置信息的场景，相关技术中并没有提供针对切换失败的优化方案。其中，具体可以优化的场景包括：
(1)对于CHO配置信息带有SCG配置信息(CHO with SCG configuration)的场景，因为配置的CHO触发条件满足后，主服务小区(Primary cell，PCell)和PSCell均需要进行随机接入过程接入到目标PCell和目标PSCell。CHO触发条件的配置需要确保当CHO触发条件满足时，满足条件的候选小区(PCell)及其相应的PSCell可以成功接入到目标PCell和目标PSCell。如果评估满足CHO触发条件，但执行时发生PCell切换失败或PSCell addition/PSCell change失败，或者CHO触发条件满足之前，终端在源小区发生RLF，则配置的CHO触发条件不合适，需要优化。
(2)对于CHO配置信息带有CPAC配置(CHO with CPAC)的场景，由于CHO和CPAC触发条件可能会同时进行评估，所以最理想的状态为CHO和CPAC触发条件可以同时满足，且均接入成功，或者CHO触发条件满足时，终端同时选到一个最好的PSCell接入，且均接入成功。以下场景说明配置的CHO或CPAC配置不合适，需要优化(包括但不限于以下场景)：
CHO触发条件满足时，CPAC触发条件没有满足或未配置CPAC触发条件，终端执行CHO成功，但是接入选择的PSCell失败；
CHO触发条件满足时，CPAC触发条件没有满足或未配置CPAC触发条件，终端执行CHO失败，但是接入选择的PSCell成功；
CHO触发条件满足时，CPAC触发条件没有满足或未配置CPAC触发条件，终端执行CHO失败，接入选择的PSCell失败；
CHO触发条件和CPAC触发条件均满足，终端执行CHO成功，但是CPAC失败；
CHO触发条件和CPAC触发条件均满足，终端执行CHO失败，但是CPAC成功；
CHO触发条件和CPAC触发条件均满足，终端执行CHO失败，但是CPAC 失败；
CHO触发条件和CPAC触发条件均未满足，终端发生RLF；
CHO触发条件未满足，CPAC触发条件满足，终端发生RLF。
针对以上场景的问题，本申请实施例提供了一种信息处理方法及装置，用以避免终端执行CHO或CPAC等失败。
其中，方法和装置是基于同一申请构思的，由于方法和装置解决问题的原理相似，因此装置和方法的实施可以相互参见，重复之处不再赘述。

满足的CPAC触发条件的信息主要包括以下：

其中，所述SCG配置信息、所述第一信息所包括的内容和含义可参照前述方法实施例的描述。
在本申请实施例中，终端在接收到网络设备发送的包括SCG配置信息的CHO配置信息时，若发生失败，终端可记录并向网络设备上报第一信息，从而使得网络设备可以根据终端上报的第一信息进行优化，以优化CHO和/或CPAC配置参数，减少CHO和/或CPAC失败，提高移动鲁棒性。
在此，网络设备指的是当前接收到第一信息的节点，而该节点并不一定就是终端失败时所在的节点，因此，当前节点需要将接收到的第一信息进行传递。因此，在上述实施例的基础上，所述网络设备可向当时终端发生失败时的源MN和/或目标MN发送所述第一信息，以使源MN通过第一接口消息向目标MN发送所述第一信息；或者目标MN通过第二接口消息向源MN发送所述第一信息；或者目标MN通过第三接口消息向目标辅节点SN发送所述第一信息，所述目标SN通过第四接口消息向MN发送所述第一信息。
其中，所述第一接口消息或所述第二接口消息或所述第三接口消息或所述第四接口消息采用以下一种或多种消息实现：
传统的XN接口消息，传统的NG接口消息，新引入的XN接口消息。
具体的，上述MN节点间传递第一信息可能涉及XN或者NG接口，可以使用相关技术中的XN接口消息接入和移动性指示(ACCESS AND MOBILITY INDICATION)或者NG接口消息下行/上行RAN配置转换(DOWNLINK/UPLINK RAN CONFIGURATION TRANSFER)，也可以使用新引入的消息；
上述MN和SN节点间传递第一信息可能涉及XN接口，可以使用相关技术中的XN接口消息SCG失败信息报告(SCG FAILURE INFORMATION REPORT)和SCG失败转换(SCG FAILURE TRANSFER)消息，也可以使用新引入的消息。
需要说明的是，通过上述接口消息传递的第一信息，可以是全部的第一信息，也可以是部分的第一信息。
可选的，在上述实施例中，网络设备接收所述终端发送的第五指示，所述第五指示用于指示所述终端记录有所述第一信息，并向所述终端发送第一请求。相应的，在步骤202中，网络设备接收所述终端响应于所述第一请求上报的所述第一信息。
网络设备在接收到上述第一信息之后，可进行相应的优化，例如调整CHO配置，调整CPAC配置等等。
以下，结合具体的实施例对本申请实施例的信息处理方法进行详细描述。
本申请实施例提供了一种信息处理方法，以便于网络进行优化。具体的，终端接收网络设备发送的CHO配置信息，其中，CHO配置信息中包括每个候选小区(候选PCell)相应的SCG配置信息。该SCG配置信息可以包括SCG侧同步重配置命令，或包括带有触发条件的CPAC配置信息，或包括不带有触发条件的CPAC配置(即配置中包括候选PSCell及其对应的同步重配置命令，但是不包括触发条件)。当终端在评估满足CHO触发条件或同时满足CHO触发条件和CPAC触发条件时，执行PCell切换和/或PSCell addition/PSCell change/CPAC失败，终端将记录失败相关信息(即第一信息)，并上报给网络设备；或在当CHO触发条件没有满足之前，终端在源小区发生RLF等失败场景下，终端将记录失败相关信息(即第一信息)，并上报给网络设备。
在本申请的一个实施例中，CHO配置信息包括SCG侧同步重配置命令。 该实施例可包括如下步骤：
步骤301：网络设备为终端配置CHO配置信息，并为CHO配置信息中的每个候选目标PCell小区配置相应的PSCell及其同步重配置命令。
步骤302：终端进行CHO触发条件的评估，并假设发生以下情况之一：

(2)终端评估满足CHO触发条件，终端执行CHO，同时执行相应的PSCell addition或PSCell change；PCell切换失败，PSCell addition或PSCell change成功；
(3)终端评估满足CHO触发条件，终端执行CHO，同时执行相应的PSCell addition或PSCell change；PCell切换成功，PSCell addition或PSCell change失败；
(4)终端评估满足CHO触发条件，终端执行CHO，同时执行相应的PSCell addition或PSCell change；PCell切换和PSCell addition或PSCell change均成功，但是短时间内终端在目标PCell发生RLF；
(5)终端评估满足CHO触发条件，终端执行CHO，同时执行相应的PSCell addition或PSCell change；PCell切换和PSCell addition或PSCell change均成功，但是短时间内终端在目标PSCell发生RLF；
(6)终端评估满足CHO触发条件，终端执行CHO，同时执行相应的PSCell addition或PSCell change，PCell切换和PSCell addition或PSCell change均成功，但是短时间内终端在目标PCell和目标PSCell均发生RLF；
(7)终端评估CHO触发条件满足前，终端发生RLF；
(8)终端评估CHO触发条件过程中，收到legacy HO(传统HO)命令，终端执行legacy HO命令失败，终端执行CHO recovery成功或失败；
(9)终端执行CHO失败，终端执行CHO recovery成功或失败；
(10)终端发生RLF，终端执行CHO recovery成功或失败。
步骤303：终端记录第一信息，包括以下一项或多项：
(1)目标PSCell的标识信息，此标识信息可以为PCI以及频点或CGI；
(2)目标PSCell的RACH信息，主要包括终端在接入PSCell过程中使用的一些RACH资源信息以及RACH过程中产生的一些信息；
(3)目标PSCell的测量结果，终端如果可以测量目标PSCell的测量结果，那么可以上报PSCell的测量结果，该测量结果可以包括小区级的测量结果和beam(波束)级的测量结果；
(4)如果之前有PSCell，终端记录源PSCell的标识信息，此标识信息可以为PCI以及频点或CGI；
(5)从接收到CHO配置信息到PSCell addition或PSCell change失败的时间间隔；
(6)从执行CHO或PSCell addition或PSCell change到PSCell addition或PSCell change失败的时间间隔；
(7)从接收到CHO配置信息到执行PSCell addition或PSCell change的时间间隔；
(8)从PSCell addition或PSCell change失败到失败上报的时间间隔；
(9)从接收到CHO配置信息到终端在目标PSCell发生RLF的时间间隔；
(10)从执行CHO到终端在目标PSCell发生RLF的时间间隔；
(11)第一指示，指示CHO配置信息中是否配置了SCG配置信息；
(12)第二指示，如果CHO配置信息中配置了SCG配置信息，指示PSCell addition或PSCell change或CPAC成功或失败；
(13)第三指示，指示CHO触发条件是否满足；
(14)目标PSCell对应的PCell标识信息，可以为PCI，以及频点或者CGI。
步骤304：终端可以通过如下的一种或多种方式来记录第一信息：
方式一：使用相关技术中的RLF报告(RLF report)来记录，即在当前的RLF report中上报上述信息，可以单独引入一个信元(Information element，IE)来存储上述所有信息，或者将上述信息一部分存储在外层，一部分存储在新引入的IE中，或者所有的上述信息均存储在外层，不引入新的IE包括这些内容；
方式二：使用SCG失败信息消息来上报上述失败信息，如在CHO执行成功，但是PSCell addition或PSCell change失败的场景下，MN是连接的，因此终端可以上报SCG失败信息消息给MN，在SCG失败信息消息中上报上述信息；
方式三：引入新的SCG侧的RLF report来记录SCG侧的第一信息，即CHO的第一信息记录在当前的RLF report中，而SCG侧的第一信息记录在新引入的SCG侧的RLF report中，但是这样分开存储失败信息需要考虑如何关联这两个RLF report报告。
其中，关联的方式可以包括使用时间戳的方式，即在两个RLF report中均加入相同的时间戳信息。该时间戳信息可以是绝对时间也可以是相对时间。或者也可以在两个RLF report中加入终端标识信息，来关联同一个终端。或者也可以生成随机数，在两个RLF report中加入相同的随机数来标识。此关联信息也可能是同时加在一个RLF report中和一个SCG失败信息消息中。另外，新引入的SCG侧的RLF report的可获得指示和获取过程可以复用当前RLF report的流程，也可以单独引入新的可获得指示或上报方式。
方式四：对于上述的场景，引入一个新的报告来记录此第一信息，即将上述所有的第一信息(MCG侧的第一信息和SCG侧的第一信息)全部记录在新引入的报告中，同时可以为新引入的报告引入新的可获得指示方式和上报方式。
方式五：将上述信息记录在其它相关技术中的报告中，如记录在SHR中，RACH Report中等。
步骤305：终端向网络设备上报所述第一信息。
在此有以下可选的两种方式上报第一信息：
方式一：
(1)终端发送上行完成消息时，发送第一指示(如可获得指示)给网络设备，指示网络设备终端记录有第一信息。其中，第一信息中所包括的内容可以一起指示或者分开指示。当终端重新接入一个PSCell，PSCell addition或PSCell change失败相关信息的可获得指示也可以单独通过SRB3(Signaling Radio Bearer，SRB，信令无线承载)发送给当前SN，由当前SN发给当前 MN，再由当前MN发送给源MN，再由源MN发给上一次PSCell addition或PSCell change失败的源和/或目标PSCell所在节点进行优化。终端也可以在SCG失败信息消息中上报一个指示信息来指示终端存储有PSCell addition或PSCell change失败相关信息。
(2)当网络设备收到终端发送的可获得指示后，网络设备发送第一请求(如，终端信息请求消息或其它请求消息)来请求终端上报记录的第一信息；
(3)终端收到网络设备发送的第一请求后，终端发送终端信息响应消息或其它响应消息来上报记录的第一信息。
方式二：终端上报SCG失败信息消息，在该信息中包括第一信息。
步骤306：网络设备获取到第一信息后，当前节点不一定为发生问题时所在的切换源或者目标网络设备节点，因此，当前节点需要将当前的失败信息发送给切换源或者目标网络设备节点，节点间传递失败信息可能涉及XN或者NG接口，可以使用相关技术中的XN接口消息ACCESS AND MOBILITY INDICATION或者NG接口消息DOWNLINK或UPLINK RAN CONFIGURATION TRANSFER，也可以使用新定义的消息；
步骤307：切换源网络设备节点分析第一信息后，可能还需要通知切换目标网络设备节点进行优化；同样的，切换目标网络设备节点分析第一信息后，也可能还需要通知切换源网络设备节点进行优化。此时，需要在源和目标网络设备节点间传递第一信息。在传递的时候，可能涉及XN或者NG接口，可以使用相关技术中的XN接口消息ACCESS AND MOBILITY INDICATION或者NG接口消息DOWNLINK或UPLINK RAN CONFIGURATION TRANSFER，也可以使用新引入的消息。
步骤308：当记录的第一信息还包括SCG侧的第一信息时，MN节点需要将SCG侧的第一信息发给SN进行分析，SN分析后可能认为MN节点需要进行优化，需要再发送消息通知MN。MN和SN节点间传递SCG侧的第一信息以及其他相关信息可能涉及XN接口，可以使用相关技术中的XN接口消息SCG FAILURE INFORMATION REPORT和SCG FAILURE TRANSFER消息，也可以使用新引入的消息。

方式二：使用SCG失败信息消息来上报上述第一信息，如在CHO执行成功，但是CPAC失败的场景下，MN是连接的，因此终端可以上报SCG失败信息消息给MN，在SCG失败信息消息中上报上述第一信息，例如CPAC失败信息；
方式三：引入新的SCG侧的RLF report来记录SCG侧的第一信息，即CHO的第一信息记录在当前的RLF report中，而SCG侧的第一信息记录在新引入的SCG侧的RLF report中。这样分开存储需考虑如何关联这两个RLF report报告。

步骤505、终端向网络设备上报所述第一信息。
在此有以下可选的两种方式上报第一信息：
方式一：
(1)终端发送上行完成消息时，发送第一指示(如可获得指示)给网络设备，指示网络设备终端记录有第一信息，也即指示网络设备终端记录有CHO失败相关信息和/或PSCell addition或PSCell change失败相关信息。上述信息可以一起指示或者分开指示。当终端重新接入一个PSCell，PSCell addition或PSCell change失败相关信息的可获得指示也可以单独通过SRB3发送给当前SN，由当前SN发给当前MN，再由当前MN发送给源MN，再由源MN发给上一次PSCell addition或PSCell change失败的源和/或目标PSCell所在节点进行优化。终端也可以在SCG失败信息消息中上报一个指示 信息来指示终端存储有PSCell addition或PSCell change失败相关信息。

在本申请的一个实施例中，终端执行CHO失败，执行CHO recovery过程也失败。在这种情况下，如果终端在评估CHO触发条件满足时，终端将执行CHO，当终端执行CHO失败，如果终端小区选择选择了一个CHO候选小 区，那么终端将执行CHO recovery过程，此时，如果CHO recovery过程失败了，终端将需要记录连续失败相关信息，在第一次CHO执行时，同时进行了一次PSCell addition或PSCell change过程或CPAC过程，当终端执行CHO recovery过程，终端将再次执行新选择的目标PCell对应的PSCell addition或PSCell change或CPAC过程，如果这两次PSCell addition或PSCell change过程或CPAC过程均失败了，那么对于SCG侧，终端也需要记录两套SCG失败相关信息，记录方法和内容可以同第一次记录SCG失败相关信息相同。
通过以上描述可以看出，在本申请实施例中，通过终端上报失败相关信息，网络设备可以进行优化以配置更合适的CHO配置来保证CHO执行时，PCell和PSCell均同步重配成功，或网络设备可以进行优化以配置更合适的CHO和/或CPAC配置保证CHO和/或CPAC成功执行，避免发生失败。
