具体实施方式
为使本公开要解决的技术问题、技术方案和优点更加清楚,下面将结合附图及具体实施例进行详细描述。在下面的描述中,提供诸如具体的配置和组件的特定细节仅仅是为了帮助全面理解本公开的实施例。因此,本领域技术人员应该清楚,可以对这里描述的实施例进行各种改变和修改而不脱离本公开的范围和精神。另外,为了清楚和简洁,省略了对已知功能和构造的描述。
应理解,说明书通篇中提到的“一个实施例”或“一实施例”意味着与实施例有关的特定特征、结构或特性包括在本公开的至少一个实施例中。因此,在整个说明书各处出现的“在一个实施例中”或“在一实施例中”未必一定指相同的实施例。此外,这些特定的特征、结构或特性可以任意适合的方式结合在一个或多个实施例中。
在本公开的各种实施例中,应理解,下述各过程的序号的大小并不意味着执行顺序的先后,各过程的执行顺序应以其功能和内在逻辑确定,而不应 对本公开实施例的实施过程构成任何限定。
本公开实施例中术语“和/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“/”一般表示前后关联对象是一种“或”的关系。
本公开实施例中术语“多个”是指两个或两个以上,其它量词与之类似。
下面将结合本公开实施例中的附图,对本公开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公开一部分实施例,并不是全部的实施例。基于本公开中的实施例,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,都属于本公开保护的范围。
在进行本公开实施例的说明时,首先对下面描述中所用到的一些概念进行解释说明。
一、多连接(Multi Connectivity,MC)。
多连接架构中,UE可能连接至一个MN,以及连接至一到多个SN,并与这些网络节点进行信令和/或数据交互。MN与SN节点均可以为LTE/e-LTE/NR节点。当有一个MN节点以及一个SN节点时,可称为双连接(Dual connection,DC)。
当UE处于连接态时,可以连接到一至多个网络侧节点,网络节点可以处于一个或者多个无线接入技术(Radio Access Technology,RAT)。例如,当MN为长期演进节点(Long Term Evolution,LTE)而SN为NR节点时,为(NG)EN-DC双连接;当MN为NR节点而SN为LTE节点时,为NE-DC双连接;当MN与SN均为NR节点时,为NR-NR-DC,双连接的架构如图1所示。
辅小区组(Secondary Cell Group,SCG)是在MR-DC下,SN节点下的服务小区组,包括一个PSCell和可能存在的一个或多个辅小区(Secondry Cells,Scells)。
二、SN变换(SN change)。
SN变换流程可以由MN或SN触发,从源SN到目标SN传递UE的上下文,同时在UE侧从源SN到目标SN改变SCG配置。
本公开的实施例提供了一种成功切换报告的处理方法及装置,用以解决在MR-DC场景下,终端和网络侧设备无法实现对SN增加或者PSCell变换的问题的记录和分析的问题。
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。
如图2所示,本公开的实施例提供了一种成功切换报告的处理方法,应用于终端,具体包括以下步骤:
步骤201、终端获取生成主辅小区成功切换报告的第一触发条件的配置信息。
所述配置信息可以包括:用于判断是否满足第一触发条件的定时器的门限值。
步骤202、若所述终端接入的辅节点SN增加或者主辅小区变换,则根据所述配置信息,在确定满足所述第一触发条件的情况下,生成第一成功切换报告;
所述主辅小区成功切换报告是包含主辅小区的相关信息的成功切换报告。所述第一成功切换报告可以是所述主辅小区成功切换报告,也可以是其他成功切换报告,即在满足所述第一触发条件时,生成的切换报告可能包括主辅小区的相关信息,也可能不包括所述主辅小区的相关信息。
步骤203、向所述终端接入的第一主节点MN发送所述第一成功切换报告。
该实施例中,在终端接入的SN节点增加或者主辅小区(PSCell)变换时,可以根据所述主辅小区成功切换报告的触发条件配置,在满足所述第一触发条件时生成第一成功切换报告,其中,在终端接入的SN增加时,主辅小区可能发生变换。所述第一成功切换报告可能为所述主辅小区成功切换报告,也可能为其他成功切换报告,例如:主小区成功切换报告。所述第一MN是所述终端上报所述第一成功切换报告时接入的MN。所述终端将所述第一成功切换报告上报给当前接入的第一MN,以使所述第一MN转发所述第一成功切换报告给其他需要进行优化的网络节点。需要说明的是,所述第一MN是所述终端要上报第一成功切换报告时接入的MN,可能与终端生成所述第 一成功切换报告时接入的MN相同,也可能不同。
本公开的实施例,支持在MR-DC场景下的SN增加或者主辅小区变换情况下生成主辅小区相关的成功切换报告,从而实现对SN增加或者主辅小区变换的问题的记录和分析,使得网络侧可以根据该成功切换报告实现对于网络节点的优化。
本公开提供的另一个实施例中,所述第一触发条件包括:在终端成功接入第一主辅小区的时刻,定时器的当前值大于所述定时器的门限值。
该实施例中,所述第一主辅小区是终端执行SN增加或者主辅小区变换后需要接入的目标主辅小区。终端执行辅节点SN增加或者主辅小区变换,在成功接入第一主辅小区的时刻,若所述定时器当前的计时时间大于该定时器的门限值,则满足所述第一触发条件,生成所述第一成功切换报告。所述定时器可以包括以下一项或者多项:
1)第一定时器,例如T304定时器或者其他新增定时器,在所述第一触发条件的配置信息中可以配置所述第一定时器的门限值,用于在终端接入的SN增加或者主辅小区变换时,判断所述终端接入第一主辅小区过程中的随机接入时长是否超时。
以所述第一定时器为T304定时器为例,T304定时器门限值可以是由终端待接入的目标PSCell分配,用于判断接入目标PSCell过程中随机接入时长是否超过了T304定时器门限值。对于新增SN节点的场景,T304定时器的门限值可以是新增的SN节点的目标小区分配;对于PSCell变换的场景,例如由PSCell A变换到PSCell B,则所述T304定时器的门限值由PSCell B小区分配。
2)第二定时器,例如T310定时器或者其他新增定时器,在所述第一触发条件的配置信息中可以配置所述第二定时器的门限值,用于在终端接收的SN增加或者主辅小区变换时,判断所述终端接入的第二主辅小区是否发生临界的无线链路失败。
以所述第一定时器为T310定时器为例,T310定时器的门限值可以由当前接入PSCell分配,用于判断源PSCell是否发生了临界的无线链路失败。
3)第三定时器,例如T312定时器或者其他新增定时器,在所述第一触 发条件的配置信息中可以配置所述第三定时器的门限值,用于判断所述SN增加或者主辅小区变换是否满足触发时间要求,即所述SN增加或者主辅小区变换是否及时触发。
以所述第一定时器为T312定时器为例,T312定时器的门限值用于判断是否及时触发了SN节点新增或者PSCell小区变换。MN和SN均可以配置该T312定时器的门限值。例如:MN节点触发所述SN增加或者主辅小区变换时,如果超过了T312定时器门限值,表示MN触发时间长,MN需要进行优化;源SN节点触发主辅小区变换时,如果超过了T312定时器门限值,表示源SN触发时间长,源SN需要进行优化。
该实施例中,在配置所述第一触发条件的配置信息时,可以通过RRC连接重配置消息发送给UE,使用信令无线承载(Signal Resource Bearer,SRB)1或者SRB3。
在SN增加或者PSCell变换过程中,如果配置了PSCell的T304定时器门限值,则在终端成功接入第一主辅小区的时刻,T304定时器当前值大于该T304定时器门限值时,触发生成所述第一成功切换报告。如果配置了PSCell的T310定时器门限值,在PSCell变换过程之前,在PSCell的T310当前值大于PSCell的T310定时器门限值时,触发生成所述第一成功切换报告。如果配置了目标PSCell测量对应的T312定时器门限值,在PSCell变换过程之前,在该测量对应的T312当前值大于T312定时器门限值时,触发生成所述第一成功切换报告。
该实施例中,所述第一主辅小区是终端执行SN增加或者主辅小区变换时需要接入的目标主辅小区。
作为一个可选实施例,所述第一成功切换报告包括以下一项:
A:主辅小区的相关信息。
该实施例中,所述第一成功切换报告可以为主辅小区成功切换报告,该主辅小区成功切换报告中包括主辅小区的相关信息。在终端满足所述第一触发条件时,生成所述第一成功切换报告,该第一成功切换报告包括主辅小区的相关信息。在该情况下,生成的所述第一成功切换报告(可以为主辅小区成功切换报告)与终端发生传统的PCell切换时生成的主小区成功切换报告 是两个独立的成功切换报告。
若所述终端同时满足所述第一触发条件和生成主小区成功切换报告的第二触发条件,则在PCell成功切换报告的基础上,再新增一份PSCell成功切换报告,即分别生成所述第一成功切换报告(可以是主辅小区成功切换报告)和所述主小区成功切换报告,所述第一成功切换报告包括主辅小区的相关信息,所述主小区成功切换报告包括主小区的相关信息。
作为一个可选实施例,所述主辅小区的相关信息包括以下一项或者多项:
1)报告触发原因;即所述主辅小区成功切换报告的触发原因,可能包含第一定时器、第二定时器、第三定时器等一项或者多项原因。
2)所述终端接入的第二主辅小区的小区标识;需要说明的是,如果触发PSCell成功切换报告时,UE存在PSCell小区,则该项存在。所述小区标识为UE的全球小区标识。所述第二主辅小区是所述终端在执行SN增加或者主辅小区变换前接入的源主辅小区。
3)所述终端接入的第二主辅小区的测量结果。
需要说明的是,如果触发PSCell成功切换报告时,UE存在PSCell小区,则该项存在。所述测量结果为:SN增加或者PSCell变换时,UE成功随机接入目标PSCell时对应的包括源小区以及各波束的参考信号接收功率(Reference Signal Received Power,RSRP)和/或参考信号接收质量(Reference Signal Received Quality,RSRQ)和/或信号与干扰加噪声比(Signal-to-noise and Interference Ratio,SINR)的测量结果。
4)所述终端接入的第一主辅小区的小区标识。
所述第一主辅小区为SN增加或者PSCell变换的目标主辅小区,小区标识为UE的全球小区标识。
5)所述终端接入的第一主辅小区的测量结果。
所述第一主辅小区为SN增加或者PSCell变换的目标主辅小区。测量结果为SN增加或者PSCell变换时,UE成功随机接入目标PSCell时对应的包括目标小区以及各波束RSRP和/或RSRQ和/或SINR的测量结果。
6)所述终端接入的第一主辅小区的邻小区的测量结果。
所述第一主辅小区为SN增加或者PSCell变换的目标主辅小区。对于UE 当前配置的测量对象,记录各测量对象的测量结果,测量结果为SN增加或者PSCell变换UE成功随机接入目标PSCell时对应的包括邻小区以及各波束RSRP和/或者RSRQ和/或者SINR测量结果。
7)所述终端接入第一主辅小区的随机接入信息。
所述目第一主辅小区为SN增加或者PSCell变换的目标主辅小区。所述主辅小区成功切换报告触发原因为第一定时器时,记录目标PSCell小区的随机接入信息。
8)SN增加时的触发节点信息。在SN节点增加时,触发节点信息为MN的PCell小区相关信息。本公开提供的另一个实施例中,可以记录上述小区的全球小区标识,或者物理小区标识(Physical Cell Identifier,PCI)和频点信息
9)主辅小区变换时的触发节点信息。当PSCell变换时,触发节点信息可能为MN节点的PCell小区相关信息或者源SN节点的PSCell小区的相关信息。本公开提供的另一个实施例中,可以记录上述小区的全球小区标识,或者PCI和频点信息。
B:所述终端接入的主小区的相关信息和主辅小区的相关信息。
该情况下,所述第一成功切换报告是可以同时包括主小区的相关信息和主辅小区的相关信息的一份报告。若所述终端同时满足所述第一触发条件和生成主小区成功切换报告的第二触发条件,则只生成一份该第一成功切换报告,分别包含主小区的相关信息和主辅小区的相关信息。
本公开提供的另一个实施例中,在该情况下,若终端仅满足第一触发条件,则生成的所述第一成功切换报告仅包括所述主辅小区的相关信息;若终端仅满足第二触发条件,则生成的所述第一成功切换报告仅包括所述主小区的相关信息。
以所述终端同时满足所述第一触发条件和生成主小区成功切换报告的第二触发条件为例,所述第一成功切换报告包括主辅小区的相关信息和主小区的相关信息,具体地,所述第一成功切换报告包括以下一项或者多项:
1)在原有PCell的成功切换报告原因(如T304定时器、T310定时器、T312定时器、双活动协议栈(DualActive Protocol Stack,DAPS)切换源侧发 生失败)的基础上再新增PSCell的第一定时器、PSCell的第二定时器、PSCell的第三定时器。触发原因可能为上述原因的一项或者多项。
2)源PSCell小区标识和目标PSCell小区标识。如果触发所述第一成功切换报告时,UE存在PSCell小区,记录源PSCell小区标识。目标PSCell小区为SN新增或者PSCell变换的目标小区。小区标识为UE的全球小区标识或者PCI和频点信息。
3)当所述第一成功切换报告触发原因为T304定时器时,记录目标PSCell小区的随机接入信息。
4)SN增加或者PSCell变换的触发节点信息。在SN节点增加时,触发节点信息为MN节点的PCell小区;当PSCell变换时,触发节点可能为MN节点PCell小区或者源SN节点PSCell小区。记录上述小区的全球小区标识,或者PCI和频点信息。
C:所述终端接入的主小区的相关信息。
本公开提供的另一个实施例中,该情况下,所述第一成功切换报告可以是主小区成功切换报告,所述在确定满足所述第一触发条件的情况下,生成所述第一成功切换报告,包括:在确定满足所述第一触发条件,且满足主小区成功切换报告的第二触发条件的情况下,记录主小区的相关信息;根据所述主小区的相关信息,生成所述第一成功切换报告(可以是所述主小区成功切换报告)。
该实施例中,由于PCell切换失败将导致通信过程中发生异常释放(即掉话),用户感受最差;而PSCell失败导致业务速率下降,相对影响较小,因此在终端同时满足所述第一触发条件和所述第二触发条件时,解决主小区问题的优先级最高,仅生成包含主小区的相关信息的所述第一成功切换报告(可以是主小区成功切换报告)。
作为一个可选实施例,所述在确定满足所述第一触发条件,且满足主小区成功切换报告的第二触发条件的情况下,记录主小区的相关信息,包括以下一项:
若确定满足所述第二触发条件的时间,早于确定满足所述第一触发条件的时间,则记录所述主小区的相关信息;
若确定满足所述第一触发条件的时间,早于确定满足所述第二触发条件的时间,则在确定满足所述第一触发条件时记录主辅小区的相关信息,在满足所述第二触发条件时,记录主小区的相关信息并删除所述主辅小区的相关信息。
该实施例中,所述主小区成功切换报告为包含主小区的相关信息的成功切换报告,例如:在终端执行主小区切换且满足所述第二触发条件时生成所述主小区成功切换报告。需要说明的是,所述主小区的相关信息包含的信息与所述主辅小区的相关信息类似,在此不做赘述。
当主小区成功切换报告先触发(即先满足第二触发条件),之后再触发主辅小区成功切换报告(即满足第一触发条件),只生成和记录所述主小区的相关信息(例如只生成主小区成功切换报告)。当主辅小区成功切换报告先触发(即先满足第一触发条件),并记录了主辅小区的相关信息(如生成了PSCell的成功切换报告),之后又触发了主小区成功切换报告(即之后满足第二触发条件),则删除之前记录的主辅小区的相关信息(或者删除生成的主辅小区成功切换报告),生成和记录主小区的相关信息(或者生成主小区成功切换报告)。
作为一个可选实施例,在生成第一成功切换报告之后,所述方法还包括:
向第一目标网络节点发送第一信息,所述第一信息指示所述终端已生成所述第一成功切换报告;
所述向所述终端接入的第一主节点MN发送所述第一成功切换报告,包括:
接收所述第一MN发送的终端信息获取请求消息;向所述第一MN发送响应消息,所述响应消息包括所述第一成功切换报告。
该实施例中,终端生成所述第一成功切换报告后,向所述第一目标网络节点发送所述第一信息,通知网络侧已经生成所述第一成功切换报告。所述第一目标网络节点接收到所述第一信息后,可以向所述第一MN发送信息获取请求,获取所述第一成功切换报告。
本公开提供的另一个实施例中,所述第一信息由以下一项或者多项消息承载:RRC连接建立完成消息;RRC连接重建立完成消息;RRC连接重配置完成消息;RRC连接恢复完成消息。
本公开提供的另一个实施例中,所述第一信息还可以由除上述消息外的其他消息承载。
该实施例中,可以在RRC连接建立完成消息、RRC连接重建立完成消息、RRC连接重配置完成消息和RRC连接恢复完成消息中的任一项或者多项消息中增加指示信息,表示UE记录了第一成功切换报告。本公开提供的另一个实施例中,所述第一信息可以指示UE同时记录了主小区成功切换报告和主辅小区成功切换报告,或者指示UE记录了主小区成功切换报告,或者指示UE记录了主辅小区成功切换报告。
所述第一MN通过触发终端信息(UE Information)获取请求消息过程,获取UE记录的主小区成功切换报告和主辅小区成功切换报告,或者获取UE记录的主小区成功切换报告,或者获取UE记录的主辅小区成功切换报告。本公开提供的另一个实施例中,可以在终端发送的响应消息(UE Information Response)中增加所述第一成功切换报告。
本公开提供的另一个实施例中,所述第一信息是所述终端成功接入第一主辅小区,且生成第一成功切换报告之后发送的。
该实施例中,所述第一主辅小区为SN增加或者PSCell变换的目标主辅小区。所述终端在记录了所述第一成功切换报告后,向终端当前接入的第一MN发送第一信息,通知网络侧获取所述第一成功切换报告。例如:所述终端可以在成功接入第一主辅小区且生成所述第一成功切换报告后,主动触发一次RRC连接重配置完成消息或者其他新增消息,消息中携带用于指示UE记录了所述第一成功切换报告的第一信息。
作为一个可选实施例,所述向第一目标网络节点发送第一信息,包括以下一项:
方式一、向所述第一MN发送所述第一信息。
该实施例中,所述第一目标网络节点是所述终端上报所述第一成功切换报告时接入的第一MN,即终端通知所述第一MN获取所述第一成功切换报告。
方式二、若所述主辅小区变换是由SN触发的SN内的主辅小区变换,则向所述SN发送所述第一信息。
该实施例中,若SN触发了SN内的主辅小区变换,则所述第一目标网络节点是触发该变换的SN节点,终端通知所述SN已生成所述第一成功切换报告,则所述SN可以向终端生成所述第一成功切换报告时接入的第二MN发送所述第二信息,使所述第二MN获取所述第一成功切换报告。
方式三、若所述主辅小区变换是由SN触发的SN内的主辅小区变换,则向所述第一MN发送所述第一信息。
该实施例中,若SN触发了SN内的主辅小区变换,所述终端也可以向接入的第一MN发送所述第一信息,通知所述第一MN获取所述第一成功切换报告。本公开提供的另一个实施例中,若所述第一MN与所述第二MN为不同的节点,所述第一MN可以将所述第一成功切换报告发送至所述第二MN。
该实施例中,SN可以通过SRB3触发SN内的PSCell变换,例如发送RRC连接重配置消息给UE,UE在SN内新的PSCell小区随机接入并发送RRC连接重配置完成消息。如果UE触发生成了所述第一成功切换报告,则所述RRC连接重配置完成消息中携带UE生成了第一成功切换报告的指示(即所述第一信息)。由于此时MN不知道发生了SN内的PSCell变换,无法触发获取所述第一成功切换报告,则可以通过上述方式二和方式三两种方法实现MN获取所述第一成功切换报告:
其中,对于方式二:SN接收到RRC连接重配置完成消息,消息中携带指示UE生成了第一成功切换报告的第一信息,SN通过XN接口通知MN进行获取(可以向MN发送第二信息),具体为使用相关技术中的XN接口消息或者新增XN消息,消息中包含UE索引信息,指示MN向对应的终端获取所述第一成功切换报告。MN获取所述第一成功切换报告后可以发送给SN。
对于方式三:在UE记录了第一成功切换报告后,UE通知MN节点获取所述第一成功切换报告,具体方式可以UE主动触发一次RRC连接重配置完成消息或者新增消息发给MN,消息中携带UE记录了第一成功切换报告的指示(即所述第一信息)。
作为一个可选实施例,所述生成第一成功切换报告之后,所述方法还包括:
按照所述终端接入的第一MN的接入技术对所述第一成功切换报告进行 编码;
或者,
按照所述终端接入的目标SN的接入技术对所述第一成功切换报告进行编码;
其中,所述第一MN的接入技术和所述目标SN的接入技术相同或者不同。
该实施例中,所述目标SN是所述终端执行所述SN增加或者主辅小区变换后接入的SN。所述终端生成所述第一成功切换报告后,可以对所述第一成功切换报告进行编码。其中,可以按照所述第一MN的接入技术进行编码,也可以按照所述终端在SN增加或者主辅小区变换后成功接入的目标SN的接入技术进行编码。
所述第一MN的接入技术和所述目标SN的接入技术可以相同也可以不同。在所述第一MN的接入技术和所述目标SN的接入技术不同的情况下,例如EN-DC场景下,第一MN为LTE接入技术,目标SN为NR接入技术,如果第一成功切换报告采用LTE技术进行编码,则第一MN可以解码,但是目标SN不一定可以解码;相反地,如果所述第一成功切换报告采用NR技术进行编码,则第一MN无法进行解码,目标SN可以解码。因此,在所述第一MN的接入技术和所述目标SN的接入技术不同时,可以通过MN与SN之间传递解码后的第一成功切换报告的内容。
例如:所述终端按照所述第一MN的接入技术对所述第一成功切换报告进行编码。则所述第一MN获取所述第一成功切换报告后,可以解码,再将解码后的第一成功切换报告的信息发送给SN。其中解码后的第一成功切换报告的信息是指以显示的方式在XN接口中直接传递的内容,而不是以容器(container)的方式传递。或者,所述终端按照目标SN的接入技术对所述第一成功切换报告进行编码,所述第一MN获取到所述第一成功切换报告后,不能解码,可以发给SN进行解码,由SN解码后将解码后的第一成功切换报告的信息发送至所述第一MN。
作为一个可选实施例,所述方法还包括;
接收条件同步重配置消息,所述条件同步重配置消息包括:候选主辅小 区列表和触发所述终端接入候选主辅小区对应的执行条件;
在满足所述执行条件的情况下,执行所述SN增加或者主辅小区变换。
该实施例中,所述SN增加或者主辅小区变换是由条件同步重配置实现的,所述终端接收网络侧发送的条件同步重配置消息,其中配置候选主辅小区列表和终端接入该候选主辅小区列表中的候选主辅小区的执行条件。所述终端接收到所述条件同步重配置消息后不立即执行所述SN增加或者主辅小区变换,而是检测执行条件,在满足执行条件时才开始执行对应的SN增加/PSCell变换操作。因此,条件同步重配置的候选主辅小区列表和对应的执行条件也是进行参数优化的必要信息。
所述条件同步重配置的候选主辅小区列表和对应的执行条件可以是网络侧保存的,也可以是终端在第一成功切换报告中记录并上报的,下面分别说明。
本公开提供的另一个实施例中,所述第一成功切换报告包括以下一项或者多项信息:
所述候选主辅小区列表;
触发所述终端接入候选主辅小区对应的执行条件;
满足所述执行条件之前最后一次接收到所述条件同步重配置消息的第一时间,与确定满足所述执行条件的第二时间之间的时间长度信息。
该实施例中,所述终端在所述第一成功切换报告中记录所述条件同步重配置的上述相关信息。例如:在终端满足所述第一触发条件生成所述第一成功切换报告时,在所述第一成功切换报告中记录条件同步重配置的候选主辅小区和对应的执行条件。
除了记录条件同步重配置的候选主辅小区列表和对应的执行条件,由于条件同步重配置发送到UE不是立即执行,而是满足执行条件再执行,因此从UE接收到条件同步重配置消息到满足所述执行条件的时间段信息也可以记录在所述第一成功切换报告中,以便网络侧可以优化条件同步重配置配置参数,避免过早配置候选主辅小区,浪费网络资源。
由于UE在满足条件同步重配置的执行条件之前,网络侧可以多次发送条件同步重配置消息增加或修改或删除候选主辅小区列表和对应的执行条件, 所述第一成功切换报告记录的时间信息具体为:UE在满足条件同步重配置执行条件之前最后一次收到条件同步重配置消息到满足条件同步重配置执行条件触发切换的时间长度信息。
本公开提供的另一个实施例中,所述第一成功切换报告包括:
与所述第一成功切换报告相关的关联信息;
标识信息,所述标识信息用于指示:所述SN增加或者主辅小区变换是通过条件同步重配置实现的。
该实施例中,网络侧保存条件同步重配置的相关信息(如候选主辅小区列表和/或对应的执行条件)。MN一直保持条件同步重配置的候选主辅小区列表和对应的执行条件,直到接收到所述第一成功切换报告。需要说明的是,每次条件同步重配置实现SN增加/PSCell变换时,如果网络侧配置了主辅小区成功切换报告的触发条件,都需要MN保存。另外,为了能够将MN保存的条件同步重配置的候选主辅小区列表和/或对应的执行条件,与所述第一成功切换报告对应起来,需要在所述第一成功切换报告增加关联信息,所述关联信息可以为以下一种或者多种:
a)时间类关联信息,例如时间节点信息,时间戳信息;
b)索引类关联信息,例如:UE的索引,如小区无线网络临时标识(Cell Radio Network Temporary Identifier,C-RNTI);
c)其他关联信息,例如随机产生的数值等。
MN节点接收到所述第一成功切换报告后,可以根据其中的关联信息由存储的候选主辅小区和/或对应的执行条件中进行查找,确定与所述第一成功切换报告对应的候选主辅小区和/或执行条件,可以与所述第一成功切换报告一起发送给需要进行优化的第二目标网络节点。
所述第一成功切换报告还可以记录标识信息,用于指示本次SN增加/PSCell变换是通过条件同步重配置实现的,需要到MN上查找对应的条件同步重配置的候选主辅小区列表和对应的执行条件。
本公开的实施例,支持在MR-DC场景下的SN增加或者主辅小区变换情况下生成主辅小区相关的成功切换报告,从而实现对SN增加或者主辅小区变换的问题的记录和分析,使得网络侧可以根据该成功切换报告实现对于网 络节点的优化。
如图3所示,本公开实施例还提供一种成功切换报告的处理方法,应用于第二MN,包括:
步骤301、第二MN获取第一成功切换报告,所述第一成功切换报告是所述终端在接入的SN增加或者主辅小区变换,且满足第一触发条件的情况下生成的;其中,所述第二MN是所述终端生成所述第一成功切换报告时接入的MN。
该实施例中,在终端接入的SN节点增加或者主辅小区(PSCell)变换时,可以根据所述主辅小区成功切换报告的触发条件配置,在满足所述第一触发条件时生成第一成功切换报告,并将所述第一成功切换报告发送至终端当前连接的第一MN,所述第一MN是所述终端上报所述第一成功切换报告时接入的第一MN。
所述第二MN与终端上报第一成功切换报告的第一MN可以相同也可以不同,例如:所述终端在生成所述第一成功切换报告后发生了MN切换,则所述第一MN与所述第二MN不同。若所述第二MN与所述第一MN不同,所述第一MN接收所述第一成功切换报告后,可以将所述第一成功切换报告发送至所述第二MN。
步骤302、所述第二MN根据所述第一成功切换报告的触发原因,确定需要优化的第二目标网络节点;
步骤303、所述第二MN向所述第二目标网络节点发送所述第一成功切换报告;
该实施例中,所述第一成功切换报告中可以包括生成该第一成功切换报告的触发原因,所述第二MN可以根据所述触发原因确定需要优化的第二目标网络节点,并将所述第一成功切换报告发送至所述第二目标网络节点,所述第二目标网络节点可以根据所述第一成功切换报告进行网络参数优化。
本公开的实施例,终端可以在MR-DC场景下的SN增加或者主辅小区变换情况下生成主辅小区相关的成功切换报告,从而实现对SN增加或者主辅小区变换的问题的记录和分析,MN节点将第一成功切换报告发送给需要优化的网络节点,实现对于网络节点的优化。
作为一个可选实施例,所述获取第一成功切换报告,包括以下一项:
(1)接收终端发送的所述第一成功切换报告。
该实施例中,所述第二MN可以是终端上报所述第一成功切换报告时接入的MN,即所述第二MN与所述第一MN相同,则终端生成所述第一成功切换报告后,直接将所述第一成功切换报告发送至所述第二MN。
(2)接收第一MN发送的所述第一成功切换报告,所述第一MN是终端上报所述第一成功切换报告时接入的MN。
该实施例中,所述第二MN与终端上报所述第一成功切换报告时接入的MN(即所述第一MN)不同,终端将所述第一成功切换报告上报所述第一MN后,所述第一MN将所述第一成功切换报告传递给所述第二MN。
该实施例中,由于接收终端发送的第一成功切换报告的MN可能不是UE生成第一成功切换报告时接入的MN,不同的MN节点间首先要传递所述第一成功切换报告到UE生成所述第一成功切换报告时时接入的MN节点(即所述第二MN),本公开提供的另一个实施例中,可以在XN和/或者NG接口上传递所述第一成功切换报告。其中,若通过XN接口传输所述第一成功切换报告,则可以复用访问和移动指示消息(ACCESS AND MOBILITY INDICATION)传递;若使用NG接口传输所述第一成功切换报告,可以复用上行链路配置传输消息(UPLINK RAN CONFIGURATION TRANSFER)和下行RAN配置传输消息(DOWNLINK RAN CONFIGURATION TRANSFER)进行传递。
本公开提供的另一个实施例中,所述第一成功切换报告包括以下一项:
A:主辅小区的相关信息。
该实施例中,所述第一成功切换报告可以为主辅小区成功切换报告,该主辅小区成功切换报告中包括主辅小区的相关信息。在终端满足所述第一触发条件时,生成所述第一成功切换报告,该第一成功切换报告包括主辅小区的相关信息。在该情况下,生成的所述第一成功切换报告(可以为主辅小区成功切换报告)与终端发生传统的PCell切换时生成的主小区成功切换报告是两个独立的成功切换报告。
若所述终端同时满足所述第一触发条件和生成主小区成功切换报告的第 二触发条件,则在PCell成功切换报告的基础上,再新增一份PSCell成功切换报告,即分别生成所述第一成功切换报告(可以是主辅小区成功切换报告)和所述主小区成功切换报告,所述主辅小区成功切换报告包括主辅小区的相关信息,所述主小区成功切换报告包括主小区的相关信息。
本公开提供的另一个实施例中,所述主辅小区的相关信息包括以下一项或者多项:
报告触发原因;
所述终端接入的第二主辅小区的小区标识;
所述终端接入的第二主辅小区的测量结果;
所述终端接入的第一主辅小区的小区标识;
所述终端接入的第一主辅小区的测量结果;
所述终端接入的第一主辅小区的邻小区的测量结果;
所述终端接入第一主辅小区的随机接入信息;
SN增加时的触发节点信息;
主辅小区变换时的触发节点信息。
B:所终端接入的主小区的相关信息和主辅小区的相关信息。
该情况下,所述第一成功切换报告是可以同时包括主小区的相关信息和主辅小区的相关信息的一份报告。若所述终端同时满足所述第一触发条件和生成主小区成功切换报告的第二触发条件,则只生成一份该第一成功切换报告,分别包含主小区的相关信息和主辅小区的相关信息。
本公开提供的另一个实施例中,在该情况下,若终端仅满足第一触发条件,则生成的所述第一成功切换报告仅包括所述主辅小区的相关信息;若终端仅满足第二触发条件,则生成的所述第一成功切换报告仅包括所述主小区的相关信息。
C:所述终端接入的主小区的相关信息。
该实施例中,由于PCell切换失败将导致通信过程中发生异常释放(即掉话),用户感受最差;而PSCell失败导致业务速率下降,相对影响较小,因此在终端同时满足所述第一触发条件和所述第二触发条件时,解决主小区问题的优先级最高,仅生成包含主小区的相关信息的所述第一成功切换报告 (可以是主小区成功切换报告)。
需要说明的是,所述第二MN接收的第一成功切换报告可以包括上述任一种信息。若所述第一成功切换报告是主小区成功切换报告,则所第二MN无需将所述第一成功切换报告发送SN。
作为一个可选实施例,所述根据所述第一成功切换报告的触发原因,确定需要优化的第二目标网络节点,包括以下一项:
若所述第一成功切换报告的触发原因是第一定时器的计时时间大于所述第一定时器的门限值,则确定所述第二目标网络节点包括以下一项或者多项:所述SN增加或者主辅小区变换的触发节点、所述终端接入的目标SN;
若所述第一成功切换报告的触发原因是第二定时器的计时时间大于所述第二定时器的门限值,则确定所述第二目标网络节点包括以下一项或者多项:所述SN增加或者主辅小区变换的触发节点、主辅小区变换前所述终端接入的源SN、触发所述SN增加或者主辅小区变换时所述终端接入的第三MN;
若所述第一成功切换报告的触发原因是第三定时器的计时时间大于所述第三定时器的门限值,则确定所述第二目标网络节点是所述SN增加或者主辅小区变换的触发节点。
该实施例中,所述第一定时器例如T304定时器或者其他新增定时器,所述第一定时器用于在终端接入的SN增加或者主辅小区变换时,判断所述终端接入第一主辅小区过程中的随机接入时长是否超时。
所述第二定时器例如T310定时器或者其他新增定时器,所述第二定时器用于在终端接收的SN增加或者主辅小区变换时,判断所述终端接入的第二主辅小区是否发生临界的无线链路失败。
所述第三定时器例如T312定时器或者其他新增定时器,所述第三定时器用于判断所述SN增加或者主辅小区变换是否满足触发时间要求,即所述SN增加或者主辅小区变换是否及时触发。
以所述第一定时器为T304定时器、所述第二定时器为T310定时器、所述第三定时器为T312定时器为例,所述第一成功切换报告的触发原因与第二目标网络节点之间的对应关系如表1所示:
表1:
其中,在T304触发生成所述第一成功切换报告时,目标PSCell接入发生了临界失败,可能是MN触发SN增加/PSCell change,或者源SN触发PSCell change的时机太早,需要MN或者源SN调整参数优化触发时机,也可能为目标SN分配的随机接入参数不合理导致,因此目标SN可能也需要做优化。
在T310触发生成所述第一成功切换报告时,源PSCell发生了临界失败,可能是MN触发SN增加/PSCell change,或者源SN触发PSCell change的时机太晚,需要MN和/或源SN调整参数优化触发时机。需要特别注意的是:触发时间太晚可能是MN和源SN同时需要优化,因为即使MN触发了PSCell change过晚,但是源SN也没有能在MN触发前进行触发,也可能是存在问题的;另一方面,也可能为源SN配置参数不合理导致发生的临界失败,因此可能也需要源SN做优化。
在T312触发生成所述第一成功切换报告时,触发节点没有及时触发SN增加/PSCell change,因此对应的触发节点需要优化。
基于上述分析,MN在获取到所述第一成功切换报告后,根据上述表1的分析结果,需要发送所述第一成功切换报告给对应的SN节点,需要增加节点间消息传递所述第一成功切换报告。可以使用相关技术中的ACCESS AND MOBILITY INDICATION消息,在消息中增加可选存在的所述第一成功切换报告。
在该实施例中,由于接收到终端发送的所述第一成功切换报告的MN不 一定是UE生成所述第一成功切换报告时接入的MN,不同的MN节点间首先需要传递所述第一成功切换报告到UE生成所述第一成功切换报告时接入的MN节点,因此需要在XN和/或者NG接口上传递PSCell成功切换报告,XN接口可以使用ACCESS AND MOBILITY INDICATION消息,NG接口使用UPLINK RAN CONFIGURATION TRANSFER和DOWNLINK RAN CONFIGURATION TRANSFER消息进行传递。
作为一个可选实施例,所述接收终端发送的所述第一成功切换报告,包括:
向所述终端发送终端信息获取请求消息;接收所述终端发送的响应消息,所述响应消息包括所述第一成功切换报告。
该实施例中,终端生成所述第一成功切换报告后,向所述第一目标网络节点发送所述第一信息,通知网络侧已经生成所述第一成功切换报告。若所述第一目标网络节点即为所述第二MN,则所述第二MN可以直接向所述终端发送终端信息获取请求消息,获取所述第一成功切换报告;若所述第一目标网络节点是SN,则所述SN可以向所述第二MN发送第二信息,通知所述第二MN终端已经生成所述第一成功切换报告,所述第二MN可以通过向所述终端发送终端信息获取请求消息获取所述第一成功切换报告。
本公开提供的另一个实施例中,在向所述终端发送终端信息获取请求消息之前,所述方法还包括:
接收终端发送的第一信息;
或者,
接收SN节点发送的第二信息,所述第二信息是所述SN节点接收到所述终端发送的第一信息后发送的,所述第二信息包括所述终端的索引信息;
其中,所述第一信息和/或所述第二信息指示所述终端已生成所述第一成功切换报告。
该实施例中,终端生成所述第一成功切换报告后,向第一目标网络节点发送所述第一信息,通知网络侧已经生成所述第一成功切换报告。其中,若所述第二MN即为所述第一目标网络节点,即所述第二MN与第一MN相同,所述终端向第二MN发送所述第一信息通知所述第二MN已生成所述第一成 功切换报告,则所述第二MN可以通过终端信息获取请求消息获取所述第一成功切换报告。
在所述主辅小区变换是由SN触发的SN内的主辅小区变换时,所述终端向SN发送所述第一信息,所述SN即为所述第一目标网络节点,所述SN可以向所述第二MN发送第二信息,通知所述第二MN已经生成所述第一成功切换报告。所述第二信息包括终端的索引信息,所述第二MN可以根据所述索引信息向对应的终端获取所述第一成功切换报告。
本公开提供的另一个实施例中,所述第一信息由以下一项或者多项消息承载:RRC连接建立完成消息;RRC连接重建立完成消息;RRC连接重配置完成消息;RRC连接恢复完成消息。
本公开提供的另一个实施例中,所述第一信息还可以由除上述消息外的其他消息承载。
该实施例中,可以在RRC连接建立完成消息、RRC连接重建立完成消息、RRC连接重配置完成消息和RRC连接恢复完成消息中的任一项或者多项消息中增加指示信息,表示UE记录了第一成功切换报告。本公开提供的另一个实施例中,所述第一信息可以指示UE同时记录了主小区成功切换报告和主辅小区成功切换报告,或者指示UE记录了主小区成功切换报告,或者指示UE记录了主辅小区成功切换报告。
本公开提供的另一个实施例中,所述向所述第二目标网络节点发送所述第一成功切换报告,包括:
复用第一接口和/或第二接口的传输消息,向所述第二目标网络节点发送所述第一成功切换报告;
其中,所述第一接口为无线接入网节点之间的网络接口,所述第二接口为无线接入网节点和核心网节点之间的网络接口。
该实施例中,所述第一接口例如XN接口,可以复用所述XN接口的ACCESS AND MOBILITY INDICATION消息传输所述第一成功切换报告。所述第二接口例如NG接口,可以复用所述NG接口的UPLINK RAN CONFIGURATION TRANSFER和DOWNLINK RAN CONFIGURATION TRANSFER消息传输述第一成功切换报告。
作为一个可选实施例,所述方法还包括:向所述终端发送条件同步重配置消息,所述条件同步重配置消息包括:候选主辅小区列表和触发所述终端接入候选主辅小区对应的执行条件。
该实施例中,所述SN增加或者主辅小区变换是由条件同步重配置实现的,网络侧向终端发送条件同步重配置消息,其中配置候选主辅小区列表和终端接入该候选主辅小区列表中的候选主辅小区的执行条件。所述终端接收到所述条件同步重配置消息后不立即执行所述SN增加或者主辅小区变换,而是检测执行条件,在满足执行条件时才开始执行对应的SN增加/PSCell变换操作。
所述条件同步重配置的候选主辅小区列表和对应的执行条件可以是网络侧保存的,也可以是终端在第一成功切换报告中记录并上报的,下面分别说明。
本公开提供的另一个实施例中,所述第一成功切换报告包括以下一项或者多项信息:
候选主辅小区列表;
触发所述终端接入候选主辅小区对应的执行条件;

该实施例中,所述终端在所述第一成功切换报告中记录所述条件同步重配置的上述相关信息。例如:在终端满足所述第一触发条件生成所述第一成功切换报告时,在所述第一成功切换报告中记录条件同步重配置的候选主辅小区和对应的执行条件。
除了记录条件同步重配置的候选主辅小区列表和对应的执行条件,由于条件同步重配置发送到UE不是立即执行,而是满足执行条件再执行,因此从UE接收到条件同步重配置消息到满足所述执行条件的时间段信息也可以记录在所述第一成功切换报告中,网络侧可以根据所述第一成功切换报告中记录的上述信息优化条件同步重配置配置参数,避免过早配置候选主辅小区,浪费网络资源。
由于UE在满足条件同步重配置的执行条件之前,网络侧可以多次发送 条件同步重配置消息增加或修改或删除候选主辅小区列表和对应的执行条件,所述第一成功切换报告记录的时间信息具体为:UE在满足条件同步重配置执行条件之前最后一次收到条件同步重配置消息到满足条件同步重配置执行条件触发切换的时间长度信息。
本公开提供的另一个实施例中,所述第一成功切换报告包括:
与所述第一成功切换报告相关的关联信息;;
标识信息,所述标识信息用于指示:所述SN增加或者主辅小区变换是通过条件同步重配置实现的。
该实施例中,网络侧保存条件同步重配置的相关信息(如候选主辅小区列表和/或对应的执行条件)。MN一直保持条件同步重配置的候选主辅小区列表和对应的执行条件,直到接收到所述第一成功切换报告。需要说明的是,每次条件同步重配置实现SN增加/PSCell变换时,如果网络侧配置了主辅小区成功切换报告的触发条件,都需要MN保存。另外,为了能够将MN保存的条件同步重配置的候选主辅小区列表和/或对应的执行条件,与所述第一成功切换报告对应起来,需要在所述第一成功切换报告增加关联信息,所述关联信息可以为以下一种或者多种:
a)时间类关联信息,例如时间节点信息,时间戳信息;
b)索引类关联信息,例如:UE的索引CRNTI;
c)其他关联信息,例如随机产生的数值等。
本公开提供的另一个实施例中,所述方法还包括:

向所述第二目标网络节点发送所述候选主辅小区列表和/或触发所述终端接入候选主辅小区对应的执行条件。
该实施例中,所述第二MN节点接收到所述第一成功切换报告后,可以根据其中的关联信息由存储的候选主辅小区和/或对应的执行条件中进行查找,确定与所述第一成功切换报告对应的候选主辅小区和/或执行条件,可以与所述第一成功切换报告一起发送给需要进行优化的第二目标网络节点。
所述第一成功切换报告还可以记录标识信息,用于指示本次SN增加 /PSCell变换是通过条件同步重配置实现的,需要到MN上查找对应的条件同步重配置的候选主辅小区列表和对应的执行条件。
作为一个可选实施例,所述向所述第二目标网络节点发送所述第一成功切换报告,包括:
向所述第二目标网络节点发送未解码的所述第一成功切换报告;
或者,
解码所述第一成功切换报告;向所述第二目标网络节点发送解码后的所述第一成功切换报告。
本公开提供的另一个实施例中,所述方法还包括:
接收所述第二目标网络节点发送的所述第一成功切换报告解码后的部分或者全部信息。

所述MN的接入技术和所述SN的接入技术可以相同也可以不同。在所述MN的接入技术和所述SN的接入技术不同时,可以通过MN与SN之间传递解码后的第一成功切换报告的内容。
所述终端按照所述MN的接入技术对所述第一成功切换报告进行编码。则MN获取所述第一成功切换报告后,可以解码,再将解码后的第一成功切换报告的信息发送给SN(即所述第二目标网络节点)。其中解码后的第一成功切换报告的信息是指以显示的方式在XN接口中直接传递的内容,而不是以容器的方式传递。或者,所述终端按照SN的接入技术对所述第一成功切换报告进行编码,MN获取到所述第一成功切换报告后,不能解码,可以发给SN进行解码,由SN解码后将解码后的第一成功切换报告的信息返回至MN。
本公开的实施例,终端可以在MR-DC场景下的SN增加或者主辅小区变换情况下生成主辅小区相关的成功切换报告,从而实现对SN增加或者主辅小区变换的问题的记录和分析,MN节点将第一成功切换报告发送给需要优 化的网络节点,实现对于网络节点的优化。

该实施例中,SN为需要优化的第二目标网络节点,所述第二MN根据获取到的第一成功切换报告的触发原因确定需要优化的第二目标网络节点为SN,则将所述第一成功切换报告发送至所述SN,所述SN根据所述第一成功切换报告记录的内容进行网络优化,例如优化网络参数。需要说明的是,所述SN可以是发生主辅小区变换时终端接入的源SN和/或目标SN,也可以是发生SN增加或者主辅小区变换时终端接入的目标SN。
本公开的实施例,终端可以在MR-DC场景下的SN增加或者主辅小区变换情况下生成主辅小区相关的成功切换报告,在所述第一成功切换报告中记录在SN增加或者主辅小区变换时的问题以及分析,MN节点将第一成功切换报告发送给需要优化的SN节点,SN节点可以根据所述第一成功切换报告实现网络优化。
