为了能够更加详尽地了解本发明实施例的特点与技术内容,下面结合附图对本发明实施例的实现进行详细阐述,所附附图仅供参考说明之用,并非用来限定本发明实施例。
本发明实施例提供了一种用于切换的信息处理方法,如图2所示,包括:
步骤21:第一网络设备向第二网络设备发送第一消息;其中,所述第二网络设备为基于终端设备上报给所述第一网络设备的测量结果确定的;所述第一消息包含以下至少之一:终端设备的第一能力组,第一网络设备的第一配置、第二网络设备的第一配置;
步骤22:第一网络设备接收所述第二网络设备反馈的第二消息;其中,所述第二消息中包含有以下至少之一:终端设备的第二能力组、第一网络设备的第二配置、第二网络设备的第二配置;
步骤23:所述第一网络设备向所述终端设备发送第二消息,所述第二消息用于指示所述终端设备进行切换。
相应的,本实施例还提供一种用于切换的信息处理方法,如图3所示,包括:
步骤31:第二网络设备接收第一网络设备发送的第一消息;其中,所述第一消息包含以下至少之一:终端设备的第一能力组,第一网络设备的第一配置、第二网络设备的第一配置;
步骤32:所述第二网络设备向第一网络设备反馈第二消息;其中,所述第二消息中包含有以下至少之一:终端设备的第二能力组、第一网络设备的第二配置、第二网络设备的第二配置。
本实施例中,网络设备可以为网络侧的基站;第一网络设备可以为终端设备连接的 源基站,第二网络设备可以为目标基站。终端设备为切换时能够同时保持与第一网络设备和第二网络设备的连接的设备。
首先针对本实施例的场景进行说明,所对应的一种切换处理,可以参见图4所示,包括:
切换准备阶段,包含图中步骤1-6:第一网络设备向终端设备发送测量控制;终端设备进行针对多个网络设备或小区的测量之后,向第一网络设备发送测量报告;第一网络设备根据测量报告(或者结合RRM信息)进行切换决策;第一网络设备向第二网络设备发送切换请求以使得第二网络设备准备进行切换;第二网络设备根据切换请求进行切换许可控制;第二网络设备确定进行切换时,向第一网络设备发送切换请求确认。
然后进行执行切换阶段,包含图中步骤7-11,具体的:第二网络设备生成RRC信息,将RRC连接重配置信息发送至第一网络设备,由第一网络设备通过RRC连接重配置信息发送至终端设备;终端设备接收到RRC连接重配置信息后,根据连接重配置信息执行切换处理;然后第一网络设备发送SN状态传输至第二网络设备;终端设备与第二网络设备进行同步,然后接收第二网络设备进行UL分配,向第二网络设备发送RRC连接重配置完成信息。
最后进入切换完成阶段,包含图中12-18,具体的:第二网络设备向MME发送路径切换请求,以通知MME终端设备改变小区;MME向服务网关发送调整承载请求,由MME进行切换下行路径处理;服务网关完成处理后,向MME发送承载调整完成处理,并由MME向第二网络设备发送路径切换请求的确认消息;第二网络设备向第一网络设备通知终端设备上下文释放由第一网络设备释放资源。
再一种切换场景,比如对于某些特殊场景,如图5所示,比如终端设备高速移动或者高频条件下,需要频繁的进行切换。有条件的切换(Conditional handover)避免了切换准备时间过长,导致终端设备要切换的时候已经过晚的问题,为终端设备提前配置切换指令(HO command)。另一方面,对于高铁场景,终端设备的运行轨迹是特定的,所以第一网络设备(第一网络设备)可以提前把第二网络设备(第二网络设备)配给终端设备,并且在HO command中包含用于触发终端设备进行切换的条件,当满足所配条件时,终端设备向第二网络设备发起接入请求。
关于这种切换场景,能够支持在配置多个目标小区,也就是能够支持配置有多个第二网络设备(第二网络设备)。终端设备在基于配置的条件进行判断的时候,可以根据其满足的条件确定与哪个第二网络设备即目标小区进行同步,接入该小区。
另外,本实施例对应的又一种切换场景还可以为包括以下两种架构:
基于双连接的切换,这种情况下,在切换时,先把第二网络设备添加为辅助接点(SN),然后通过角色转换信令来把SN变为主节点(MN),最后再把第一网络设备释放掉,从而达到切换时候中断时间减小的效果。
另一架构为基于eMBB的切换,这种切换基于图4的切换流程,不同在于终端设备在收到切换指令(HO command)时,继续保持和第一网络设备的连接同时向第二网络设备发起随机接入,知道终端设备与第二网络设备接入完成才释放第一网络设备的连接。
本实施例中,所述终端设备的第一能力组与所述终端设备的第二能力组中均包含有至少一个能力;
且所述终端设备的第一能力组与所述终端设备的第二能力组中包含的能力相同,或者至少部分不同。
终端设备的能力可分为无线接入相关能力、及核心网相关能力。
所述终端设备的第一能力组,包含以下至少之一:
终端设备的第一能力集合;其中,所述第一能力集合中包含有终端设备的总能力;
终端设备的第二能力集合;其中,所述第二能力集合为终端设备切换时同时保持与第一网络设备和第二网络设备的连接时第一网络设备侧终端设备的能力;
终端设备的第三能力集合;其中,所述第三能力集合为终端设备切换时同时保持与第一网络设备和第二网络设备的连接时第二网络设备侧终端设备的能力;
终端设备的第四能力集合;所述第四能力集合为终端设备切换之前第一网络设备侧终端设备的能力;
终端设备的第五能力集合;所述第五能力集合为第一能力集合除去第四能力集合中的能力之外剩余的能力。
所述终端设备的第二组能力,包含以下至少之一:
终端设备的第一能力集合;其中,所述第一能力集合中包含有终端设备的总能力;
终端设备的第二能力集合;其中,所述第二能力集合为终端设备切换时同时保持与第一网络设备和第二网络设备的连接时第一网络设备侧终端设备的能力;
终端设备的第三能力集合;其中,所述第三能力集合为终端设备切换时同时保持与第一网络设备和第二网络设备的连接时第二网络设备侧终端设备的能力;
终端设备的第四能力集合;所述第四能力集合为终端设备切换之前第一网络设备侧终端设备的能力;
终端设备的第五能力集合;所述第五能力集合为第一能力集合除去第四能力集合中的能力之外剩余的能力。
第一能力组与第二能力组中包含的具体内容可能不同,或者至少部分不同。比如,第一能力组中可以包含第一能力集合,第二能力组中可以包括第二能力集合。也就是说,第一网络设备向第二网络设备发送第一消息的时候,其中第一能力组中可以包括第一能力集合、第二能力集合;第二网络设备向第一网络设备反馈第二消息的时候,其中第二能力组可以包括有第三能力集合以及第五能力集合。可能存在的多种情况,本实施例中不做穷举。
另外,上述多个能力集合中包含的终端设备的能力为一个或多个能力;比如,第一能力集合中包含有终端设备的总能力,该终端设备的总能力为终端设备能够具备全部的能力中的至少部分。同样的,第二能力集合、第三能力集合,虽然为终端设备在切换时的第一网络设备侧终端设备的能力;以及在第二网络设备侧终端设备的能力,也可以理解为终端设备能够具备全部的能力中的至少部分,只是对应在第一网络设备以及第二网络设备侧的终端设备的能力可能至少部分不同。
还需要指出的是,第一网络设备的第一配置,第一网络设备的第二配置,可以基于第二能力集合确定;第二网络设备的第一配置,第二网络设备的第二配置,可以基于第三能力结合确定。并且,所述第一网络设备的第一配置与第一网络设备的第二配置相同或不同;和/或,所述第二网络设备的第一配置和/或第二网络设备的第二配置相同或不同。

场景3、由第二网络设备进行配置和/或能力的修改的处理场景,具体的:

进一步,该消息中可以第一网络设备的第二配置和第二网络设备的第二配置,所述第一网络设备的第二配置和第二网络设备的第二配置是第二网络设备基于UE能力配置的。

6、第一网络设备收到该handover request Ack消息,保存其中的配置并在切换命令中转发给UE。
当然,本场景中第一网络设备可以不对第二消息进行修改,也可以对第二消息进行修改或调整,具体方式与场景2相同,这里不再赘述。
关于前述场景,切换请求消息中包含有切换准备信息(HandoverPreparationInformation),其一种信息单元(IE)的示例可以如下:
其中,“UE-CapabilityRAT-ContainerLis”表征终端设备的能力。
关于切换请求反馈消息的内容可以如下:
本实施例提供的方案中,还可以包括有针对目标业务的切换处理,具体说明如下:
当终端设备的能力满足目标业务的切换要求时,向第二网络设备发送针对目标业务的切换的指示信息;其中,所述目标业务可以为eMBB或DC。
接收第二网络设备的反馈信息。
其中,第一网络设备根据终端设备的能力组来判断所述终端设备是否满足目标业务的切换需求。
所述指示信息由切换请求消息携带;所述反馈信息由切换请求确认消息携带。
举例来说,第一网络设备可以在发送给第二网络设备的切换请求消息中增加针对目标业务的切换的指示信息,和/或对应的配置信息。其中,所述配置信息中可以包含有载波数量等等,这里不做穷举。
相应的,所述第二网络设备接收第一网络设备发送的针对目标业务的切换的指示信息,向第一网络设备发送反馈信息。
其中,第二网络设备接收到针对目标业务的切换的指示信息之后,第二网络设备基于该指示信息,判断自身是否可以支持针对目标业务的切换需求。比如,可以根据自身的配置和/或能力来判断自身是否可以支持目标业务的切换,当确定所述第二网络设备支持目标业务切换时,在反馈信息中添加针对目标业务的指示以及配置;当确定所述第二网络设备不支持目标业务切换时,在反馈信息中添加非确认信息,比如为NACK信息。
相应的,当所述第二网络设备的反馈信息中包含针对目标业务的指示时,所述第一网络设备确定所述第二网络设备支持目标业务切换,从所述反馈信息中获取针对目标业务的配置。
上述目标业务为eMBB或DC。结合图7,对目标业务为eMBB为例进行说明:若第二网络设备在切换请求确认(handover request ack)消息中携带了指示信息并且指示信息对应eMBB,就代表第二网络设备支持eMBB切换并且所携带的配置也是基于eMBB的。
其中,可以针对目标业务设置对应的标识位,比如,当切换请求消息或切换请求确认消息为针对目标业务的时候,可以将该标识位置1,否则可以置0;也就是说,当切换请求消息携带了针对目标业务的切换的指示信息的时候,可以将该目标业务对应的标识位置1;当切换请求确认消息表征第二网络设备支持该目标业务的切换的时候,同样的可以将该目标业务对应的标识位置1,否则置0。当然这仅为示例,当确认包含目标业务的时候也可以将标识为设置为0,均根据实际情况的设置来确定,本实施例不再赘述。
可见,通过采用上述方案,就能在第一网络设备和第二网络设备之间交互的第一消息以及第二消息中,指示终端设备的能力和/或网络设备的配置,进而可以将能力和/或配置传输给终端设备。如此,就实现了在切换流程中,第一网络设备以及第二网络设备之间进行终端设备的能力和/或网络设备的配置的协调。

当然,本场景中第一网络设备可以不对第二消息进行修改,也可以对第二消息进行修改或调整,具体方式与场景2相同,这里不再赘述。
本实施例提供的方案中,还可以包括有针对目标业务的切换处理,具体说明如下:
第一网络设备的第一通信单元51,当终端设备的能力满足目标业务的切换要求时,向第二网络设备发送针对目标业务的切换的指示信息;其中,所述目标业务可以为eMBB或DC。
所述第一通信单元51,还可以接收第二网络设备的反馈信息。
其中,第一网络设备的第一处理单元52根据终端设备的能力组来判断所述终端设备是否满足目标业务的切换需求。
所述指示信息由切换请求消息携带;所述反馈信息由切换请求确认消息携带。
相应的,所述第二网络设备的第二通信单元61接收第一网络设备发送的针对目标业务的切换的指示信息,向第一网络设备发送反馈信息。
其中,第二网络设备接收到针对目标业务的切换的指示信息之后,第二网络设备基于该指示信息,判断自身是否可以支持针对目标业务的切换需求。比如,可以根据自身的配置和/或能力来判断自身是否可以支持目标业务的切换,当确定所述第二网络设备支持目标业务切换时,在反馈信息中添加针对目标业务的指示以及配置;当确定所述第二网络设备不支持目标业务切换时,在反馈信息中添加非确认信息,比如为NACK信息。
相应的,当所述第二网络设备的反馈信息中包含针对目标业务的指示时,所述第一网络设备的第一处理单元52确定所述第二网络设备支持目标业务切换,从所述反馈信息中获取针对目标业务的配置。
可见,通过采用上述方案,就能在第一网络设备和第二网络设备之间交互的第一消息以及第二消息中,指示终端设备的能力和/或网络设备的配置,进而可以将能力和/或配置传输给终端设备。如此,就实现了在切换流程中,第一网络设备以及第二网络设备之间进行终端设备的能力和/或网络设备的配置的协调。
