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,所描述的实施例是本公开一部分实施例,而不是全部的实施例。基于本公开中的实施例,本领域普通技术人员在没有作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。
请参阅图1,为本公开实施例提供的一种数据传输方法的流程图;具体可以包括如下步骤:
步骤101:用户设备(UE,User Equipment)向网络设备发起随机接入请求或资源请求;
该步骤中,如果UE想接入网络,需要通过随机接入信道(Random Access Channel,RACH)向网络设备发起随机接入请求;或者是,UE自主向网络侧的网络设备发起资源请求,请求资源分配等,如SI request等。
其中,随机接入请求中包括:随机接入的类型,比如连接请求或/波束故障恢复(beam failure recovery)或/和切换过程中随机接入信道。
其中,所述用户设备UE向网络设备发起随机接入请求,具体包括:
所述UE通过竞争随机接入信道或非竞争随机接入信道向网络设备发起随机接入请求;其中,所述竞争随机接入信道或非竞争随机接入信道包括:
辅助上行链路SUL载波、非辅助上行链路SUL载波或带宽部分BWP。
步骤102:所述UE记录随机接入失败信息或资源请求失败信息;
该步骤中,UE在发起随机接入过程或者资源请求过程中,可能一次连接成功,也可以多次才能连接成功。在连接失败时,要记录连接失败信息,比如,如果是随机接入请求失败,则需要记录的至少包括下述一种:随机接入的相关参数,UE的相关参数、小区信号质量参数以及随机接入失败次数等,其中,随机接入的相关参数又可以包括:随机接入信道类型,随机接入的过程参数以及随机接入失败的小区参数等,但并不限于此还可以根据需要记录其他参数,本实施例不做限制;如果是资源请求失败,则记录资源请求失败信息包括:资源请求的当前小区信号质量参数以及资源请求失败次数等,但并不限于此还可以根据需要记录其他参数,本实施例不做限制。
步骤103:所述UE在检测到所述UE成功接入到所述网络设备时,向所 述网络设备发送所述随机接入失败信息或资源请求失败信息,以便于所述网络设备根据所述随机接入失败信息对随机接入参数进行优化或根据所述资源请求失败信息对资源请求的小区参数进行优化。
该步骤中,UE通过一次或多次连接失败,最后成功接入网络设备的情况分为下述几种:
第一种是,UE向第一网络中的第一网络设备发起随机接入失败或资源请求失败,并在失败后,继续向所述第一网络中的第一网络设备发起随机接入或资源请求,直至成功连接;也就是说,UE向同一网络中的同一个网络设备发起一次或多次随机接入请求或资源请求,直至成功连接;
第二种是,UE向第一网络中的第一网络设备发起随机接入失败或资源请求失败,并在失败后,向第一网络中的第二网络设备发起随机接入请求或资源请求,直至成功连接;也就是说,当UE向网络中的一个网络设备发起随机接入请求或资源请求,并在请求失败后,继续向该网络中的其他网络设备发起随机接入请求或资源请求,直至成功连接;
第三种是,UE向第一网络中的第一网络设备发起随机接入失败或资源请求失败,并在失败后,向第二网络中的第一网络设备发起随机接入或资源请求,直至成功连接;也就是说,当UE向网络中的一个网络设备发起随机接入请求或资源请求,并且请求失败后,可以向其他网络中的网络设备发起随机接入请求或资源请求,直至成功连接。需要说明的是,UE向其他网络中的网络设备发起随机接入请求或资源请求的过程,与上述过程类似,具体过程详见上述,在此不再赘述。
之后,在检测到所述UE成功接入到所述网络设备时,向所述网络设备发送所述随机接入失败信息或资源请求失败信息,以便于所述网络设备将所述随机接入失败信息或资源请求失败信息发送给网管进行参数优化处理。比如,网管(即收集记录网元等)根据UE上报的随机接入的相关参数和/或UE的相关参数和/或小区信号质量参数,调整RACH相关参数或提高小区的RACH接入容量。或者,网络设备根据UE上报的小区信号质量参数(比如资源请求的当前小区信号质量参数等),调整SI请求相关参数。
本公开实施例中,UE在向网络设备发起随机接入请求或资源请求失败后, 记录随机接入失败信息或资源请求失败信息,并将该随机接入失败信息或资源请求失败信息发送给网络设备,以便于网络设备上报给网管及时对参数进行优化处理。也就是说,采用本公开实施例提供的技术方案,可以在随机接入失败或资源请求失败后,记录随机接入失败信息或资源请求失败信息,并将该记录的随机接入失败信息或资源请求失败信息上报给网络设备,以便于网络设备通过网管对随机接入参数或资源请求的小区参数及时进行优化处理,从而提高了随机接入或资源分配的效率。
可选的,在另一实施例中,该实施例在上述实施例的基础上,在检测到所述UE成功接入到所述网络设备时,所述方法还可以包括:
1)所述UE向所述网络设备请求是否发送记录的所述随机接入失败信息或所述资源请求失败信息;
该步骤中,在UE成功接入到所述网络设备时,UE向接入的网络设备请求是否发送记录和保存随机接入失败信息或资源请求失败信息;该网络设备接收到该请求后,根据需要决定是否同意,如果需要,则向UE发送同意发送随机接入失败信息或资源请求失败信息的指示,否则,向UE发送不同意的指示。
2)接收所述网络设备同意发送所述随机接入失败信息或所述资源请求失败信息的指示;
该步骤中,如果网络设备向UE发送了同意发送的指示,即UE接收到网络设备发送同意的指示。
3)根据所述指示,执行所述UE向所述网络设备发送所述随机接入失败信息或所述资源请求失败信息的步骤。
该步骤中,UE在接收到同意发送的指示后,向该网络设备发送所述随机接入失败信息或所述资源请求失败信息。
一种实施例中,UE可以通过无线资源控制消息或专用信令向该网络设备发送所述随机接入失败信息或所述资源请求失败信息。
本公开实施例中,在UE成功接入到网络时,向所述网络设备请求是否发送记录的所述随机接入失败信息或所述资源请求失败信息,并在接收到网络设备发送的同意发送的指示后,将该随机接入失败信息或所述资源请求失 败信息发送给网络设备。也就是说,该实施例与上述实施例的不同之处在于,在UE成功接入到网络后,并没有及时将记录的随机接入失败信息或资源请求失败信息发送给接入的网络设备,而是向该网络设备请示(或指示)是否需要发送该随机接入失败信息或资源请求失败信息,并在接收到网络设备的同意发送的指示后,才将记录的随机接入失败信息或资源请求失败信息发送给该网络设备;以便于网络设备上报给网管对参数进行优化处理。也就是说,采用本公开实施例提供的技术方案,可以在随机接入失败或资源请求失败后,记录随机接入失败信息或资源请求失败信息,并将该记录的随机接入失败信息或资源请求失败信息上报给网络设备,以便于网络设备通过网管对随机接入参数或资源请求的小区参数进行优化处理,从而提高了随机接入或资源分配的效率。
还请参阅图2,为本公开实施例提供的一种参数优化方法的流程图,所述方法可以包括:
步骤201:第一网络设备接收用户设备UE发送的随机接入失败信息或资源请求失败信息;
该步骤中,当UE成功接入网络时,向接入网络中的第一网络设备发送记录的随机接入失败信息或资源请求失败信息。
其中,该随机接入失败信息至少包括下述一种:随机接入的相关参数,UE的相关参数、小区信号质量参数以及随机接入失败次数;随机接入的相关参数包括:随机接入信道的类型、随机接入的过程参数以及随机接入失败的小区参数等。
所述资源请求失败信息包括:资源请求的当前小区参数以及资源请求失败次数。
步骤202:所述第一网络设备根据所述随机接入失败信息或资源请求失败信息判断自身是否是记录随机接入失败信息或资源请求失败信息的第一网络设备;如果是,执行步骤203;否则,结束流程;
该步骤中,第一网络设备根据接收到的所述随机接入失败信息或资源请求失败信息中的标识判断自身是否是该UE随机接入失败或资源请求失败的网络设备,如果是,执行步骤203;如果否,进一步还可以执行步骤204;
步骤203:所述第一网络设备将接收到的所述随机接入失败信息或资源请求失败信息上报给网管,以便于所述网管对随机接入参数或资源请求的小区参数进行优化处理。
步骤204:所述第一网络设备将接收到的所述随机接入失败信息或资源请求失败信息转发给所述随机接入失败信息或资源请求失败信息中记录的第二网络设备,以便于所述第二网络设备将所述随机接入失败信息或资源请求失败信息上报给网管进行参数优化处理。
也就是说,如果第一网络设备根据接收到的所述随机接入失败信息或资源请求失败信息中的标识判断自身不是该UE随机接入失败或资源请求失败的网络设备,则将接收到的所述随机接入失败信息或资源请求失败信息转发给所述随机接入失败信息或资源请求失败信息中记录的第二网络设备,以便于所述第二网络设备将所述随机接入失败信息或资源请求失败信息上报给网管进行参数优化处理。
比如,网管(即收集记录网元等)根据UE上报的随机接入的相关参数和/或UE的相关参数和/或小区信号质量参数,调整RACH相关参数或提高小区的RACH接入容量。或者,网管根据UE上报的小区信号质量参数,调整SI请求的相关参数等。
可选的,在另一实施例中,该实施例在上述实施例的基础上,在第一网络设备接收到UE发送的随机接入失败信息或资源请求失败信息前,所述方法还可以包括:
所述第一网络设备接收所述UE请求是否发送记录的所述随机接入失败信息或所述资源请求失败信息的指示;
所述第一网络设备向所述UE发送同意发送所述随机接入失败信息或所述资源请求失败信息的指示。
也就是说,该实施例中,UE在成功连接到网络设备后,向该网络设备发送记录的随机接入失败信息或所述资源请求失败信息前,会先请示与其连接的网络设备是否同意发送,如果网络设备同意,则向UE发送同意的指示,如果不同意,则向UE发送不同意的指示,UE会根据接收到的指示来决定,是否将连接失败时记录的随机接入失败信息或所述资源请求失败信息发送给 该网络设备。
本公开实施例中,在UE成功连接时,网络设备会接收到UE发送的随机接入失败信息或资源请求失败信息,并根据该信息中的标识判断自身是不是该UE随机接入失败或资源请求失败的网络设备,如果是,则直接将随机接入失败信息或资源请求失败信息发送给网管,以便于所述网管对随机接入参数或资源请求的小区参数进行优化处理;如果不是,则将接收到的所述随机接入失败信息或资源请求失败信息转发给所述随机接入失败信息或资源请求失败信息中记录的第二网络设备,以便于所述第二网络设备将所述随机接入失败信息或资源请求失败信息上报给网络设备进行参数优化处理。也就会说,采用把公开实施例提供的技术方案,可以在随机接入失败或资源请求失败后,记录随机接入失败信息或资源请求失败信息,并将该记录的随机接入失败信息或资源请求失败信息上报给网络设备,以便于网络设备通过网管对随机接入参数或资源请求的小区参数进行优化处理,从而提高了随机接入或资源分配的效率。

该步骤中,UE在连接或INACTIIVE状态下或当UE在连接于网络时:其具体的连接过程包括下述几种情况:
第一种情况:如果UE在网络1的网络设备1发生RACH失败,RACH失败后UE在网络1的网络设备1继续连接,直到成功连接到网络1的网络设备1上。
第二种情况:如果UE在网络1的网络设备1发生RACH失败,RACH失败后,UE在网络1的网络设备2成功连接。
第三种情况:如果UE在网络1的网络设备1发生RACH失败,RACH失败后,UE在网络2的网络设备1成功连接。
之后,无论UE通过上述那种情况成功连接,UE都会向连接成功的所述网络设备发送所述资源请求失败信息;
进一步,UE成功连接后,还可以向所述网络设备请求是否发送记录的所述资源请求失败信息,具体的,UE可以通过无线资源控制RRC消息或专用 信令向所述网络设备发送所述资源请求失败信息。其中,RRC消息,比如MSG1/3/5等。如果接收到网络设备发送同意发送的指示,则将资源请求失败信息发送给该网络设备。
比如,UE在LTE发生过RRC connection失败,UE可上报给LTE也可上报给5G或WLAN或3G等通信网等。
4、网络设备接收到用户设备UE发送的资源请求失败信息;
一种情况是,网络设备直接接收到UE发送的资源请求失败信息,
另一种情况是,网络设备先接收到UE发送的请求发送资源请求失败信息的指示,然后向该UE发送同意发送的指示后,接收到UE发送的资源请求失败信息。
其中,网络设备向UE发送同意发送的指示可以通过下述方式来实现:
该同意的指示信息可包含于已有的RRC消息中,如MSG2/4/6,当然,也可以包括如RRC重配消息,RRC suspend消息,RRC release消息中等,当然,也可以通过网络用专用信令来指示UE上传记录的资源请求失败信息。
5、网络设备根据所述资源请求失败信息判断自身是否是记录资源请求失败信息的网络设备;
该步骤中,资源请求失败信息中还可以包括资源请求失败的小区或网络设备的标识,以便于接收该资源请求失败消息的网络设备判断自身是否是资源请求失败信息中记录的网络设备。
6、所述网络设备将接收到的所述资源请求失败信息上报给网管(即收集记录网元),以便于所述网管对资源请求的小区参数进行优化处理。
7、网管根据UE上报的小区信号质量参数,调整SI请求相关参数。
