本公开实施例提供了一种连接处理方法,该方法应用于终端设备,可以由终端设备执行。图2为本公开实施例提供的连接处理方法的流程示意图,如图2所示,该方法至少包括如下步骤:
步骤102,接收配置信息,该配置信息包括用于移动性过程中同时保持源节点和目标节点连接的第一连接配置信息,以及用于重配置和目标节点连接的第二连接配置信息。
在具体实施时,步骤102中接收配置信息可以是网络侧设备发送的。该配置信息可以为针对终端设备连接节点切换命令、SCG添加连接节点或者改变SCG的连接节点的命令的配置信息。
其中,源节点可以理解为终端设备当前所连接的节点,目标节点可以理解为需要添加的、切换到的或者改变为的节点。具体的,源节点可以为终端设备在移动性过程中的源小区、源基站、源MN或者源SN;目标节点可以为 终端设备在移动性过程中的目标小区、目标基站、目标MN或目标SN。

具体的,在步骤104中,基于上述配置信息执行连接操作包括:在移动性过程中基于第一连接配置信息执行第一连接操作,以及基于第二连接配置信息执行第二连接操作。
其中,上述执行第一连接操作可以是在保持与源节点的连接的基础上,建立与目标节点的连接;上述执行第二连接操作可以是重配置与目标节点的连接,同时释放与源节点的连接。

在本公开实施例中,若检测到第一连接操作失败,则执行第一连接操作所对应的处理过程;若检测到第二连接操作失败,则执行第二连接操作所对应的处理过程。
本说明书实施例提供的连接处理方法,在移动性过程中,分别基于第一连接配置信息和第二连接配置信息执行相应的连接操作,通过检测相应的连接操作是否失败,可以及时发现失败的连接操作,并采用与该连接操作相对应的处理过程进行处理,从而实现了移动过程中不同的连接操作失败的合理处理,使得失败的连接可以快速恢复,减少数据的丢失。
在本公开实施例中,可以采用不同的方法检测连接操作是否失败,相应的,针对不同的方法检测到的连接操作失败的类型可能存在差异,进而需要通过不同的处理过程进行处理。下述将详细介绍上述步骤104中的具体检测过程,步骤106中所对应的具体处理过程。
具体的,步骤104中,可以通过设置于终端设备上的定时器检测连接操作是否失败,通过该种方式检测到的连接失败类型则为定时器超时所导致的连接失败。其中,通过定时器检测连接操作是否失败至少可以通过如下两种 方式实现,下述将分别进行介绍。
方式一,
通过第一定时器对第一连接配置信息所对应的第一连接操作进行计时,基于第一定时器的计时结果检测第一连接操作是否失败;通过第二定时器对第二连接配置信息所对应的第二连接操作进行计时,基于第二定时器的计时结果检测第二连接操作是否失败。
在本公开实施例中,则是在终端设备上设置有第一定时器和第二定时器两个定时器,通过第一定时器检测第一连接操作是否失败,通过第二定时器检测第二连接操作是否失败。
其中,上述通过第一定时器对第一连接配置信息所对应的第一连接操作进行计时的具体过程可以为:
在基于第一连接配置信息执行第一连接操作时,启动第一定时器;当建立第一连接时,停止第一定时器。
在具体实施时,可以将第一定时器从启动时刻到停止时刻的时长,确定为第一定时器的计时结果;其中,第一定时器的时长用于表示第一连接操作的连接时长。例如,可以记录在启动时第一定时器的第一计时时刻,以及记录停止时第一定时器的第二计时时刻,使用第二定时时刻减去第一定时时刻,则为第一定时器所计时的时长,将第一定时器的时长确定为第一定时器的计时结果。
当然,上述只是介绍了确定第一定时器的计时结果的一种具体实现方式,在本领域中确定定时器的计时结果的具体实现方式并不止上述一种,还可通过其它方式实现,此处只是示例性说明,并不构成对本公开实施例的限定。
另外,在本公开实施例中,在开始执行第一连接操作时,启动第一定时器;当建立第一连接(即建立了第一连接)时,停止第一定时器。因此,为了能够确定何时停止第一定时器,需要判断是否建立了第一连接。
在本公开实施例中,可以通过以下方式中的至少一种判断是否建立了第一连接:
(1)若接收到网络侧设备发送的到目标节点的随机接入过程完成的指示信息,则确定建立了第一连接;
(2)若检测到终端设备向网络侧设备发送第一连接建立完成的确认信息,则确定建立了第一连接;
(3)若接收到网络侧设备发送的第一连接建立完成的确认信息,则确定建立了第一连接。
具体的,可以是通过上述方式中的任意一种方式、任意两种方式的组合或者三种方式判断是否建立了第一连接。
当然,本公开实施例只是列举了判断是否建立了第一连接的三种具体实现过程,判断是否建立了第一连接还可以通过其他方式实现,即判断是否建立了第一连接的具体方式并不局限于此,此处不再一一列举。
下述将详细介绍上述三种方式的具体实现过程。
在本公开实施例中,当终端设备在基于第一连接配置信息执行第一连接操作时,会触发执行到目标节点的随机接入过程,因此,可以通过检测随机接入过程是否完成来检测是否建立了第一连接。具体的,在上述(1)中,可以实时或者按照设定时间间隔检测是否接收到网络侧设备发送的到目标节点的随机接入过程完成的指示信息,若检测到接收到了网络侧设备发送的该指示信息,则确定建立了第一连接。
当终端设备在建立了第一连接后,会向网络侧设备发送RRC配置完成的消息,因此,上述(2)中的第一连接建立完成的确认信息可以为RRC配置完成的消息。具体的,在上述(2)中,可以实时或者按照设定时间间隔检测终端设备是否向网络侧设备发送第一连接建立完成的确认信息,若是检测到终端设备向网络侧设备发送了上述确认信息,则确定建立了第一连接。
另外,在本公开实施例中,若终端设备建立了第一连接,则网络侧设备会向终端设备发送RRC配置完成的消息。因此,在上述(3)中,网络侧设备发送的第一连接建立完成的确认信息可以为RRC配置完成的消息。具体的,在上述(3)中,可以实时或者按照设定时间间隔检测终端设备是否接收到网络侧设备发送的第一连接建立完成的确认信息,若是检测到网络侧设备发送的上述确认信息,则确定建立了第一连接。
需要说明的是,在本公开实施例中,上述(1)、(2)、(3)中,可以通过与源节点的连接与网络侧设备之间进行数据传输。
具体的,在该种实现方式中,上述通过第二定时器对第二连接配置信息所对应的第二连接操作进行计时,具体包括:
在基于第二连接配置信息执行第二连接操作时,启动第二定时器;当建立第二连接操作时,停止第二定时器。
在具体实施时,可以将第二定时器从启动时刻到停止时刻的时长,确定为第二定时器的计时结果;其中,第二定时器的时长用于表示第二连接操作所对应的连接时长。例如,可以记录在启动时第二定时器的第一计时时刻,以及记录停止时第二定时器的第二计时时刻,使用第二定时时刻减去第一定时时刻,则为第二定时器所计时的时长,将第二定时器的时长确定为第二定时器的计时结果。
当然,上述只是介绍了确定第二定时器的计时结果的一种具体实现方式,在本领域中确定定时器的计时结果的具体实现方式并不止上述一种,还可通过其它方式实现,此处只是示例性说明,并不构成对本公开实施例的限定。
另外,在本公开实施例中,在开始执行第二连接操作时,启动第二定时器;当建立第二连接(即建立了第二连接)时,停止第二定时器。因此,为了能够确定何时停止第二定时器,需要判断是否建立了第二连接。
1)若接收到网络侧设备发送的目标节点的随机接入过程完成的指示信息,则确定建立了第二连接;
2)若检测到终端设备向网络侧设备发送第二连接建立完成的确认信息,则确定建立了第二连接;
3)若接收到网络侧设备发送的第二连接建立完成的确认信息,则确定建立了第二连接。
具体的,可以是通过上述方式中的任意一种方式判断是否建立了第二连接;或者,还可以通过上述方式中的任意两种方式组合判断是否建立了第二连接;还或者,同时上述三种方式组合判断是否建立了第二连接。
当然,本公开实施例只是列举了判断是否建立了第二连接的三种具体实现过程,判断是否建立了第二连接还可以通过其他方式实现,即判断是否建立了第二连接的具体方式并不局限于此,此处不再一一列举。
在本公开实施例中,当终端设备在基于第二连接配置信息执行第二连接 操作时,会触发执行到目标节点的随机接入过程,因此,可以通过检测到目标节点的随机接入过程是否完成来检测是否建立了第二连接。具体的,在上述1)中,可以实时或者按照设定时间间隔检测是否接收到网络侧设备发送的到目标节点的随机接入过程完成的指示信息,若检测到接收到了网络侧设备发送的该指示信息,则确定建立了第二连接。
当终端设备在建立了第二连接后,会向网络侧设备发送RRC配置完成的消息,因此,上述2)中的第二连接建立完成的确认信息可以为RRC配置完成的消息。具体的,在上述2)中,可以实时或者按照设定时间间隔检测终端设备是否向网络侧设备发送第二连接建立完成的确认信息,若是检测到终端设备向网络侧设备发送了上述确认信息,则确定建立了第二连接。
另外,在本公开实施例中,若终端设备建立了第二连接,则网络侧设备会向终端设备发送RRC配置完成的消息。因此,在上述3)中,网络侧设备发送的第二连接建立完成的确认信息可以为RRC配置完成的消息。具体的,在上述3)中,可以实时或者按照设定时间间隔检测终端设备是否接收到网络侧设备发送第二连接建立完成的确认信息,若是检测到网络侧设备发送的上述确认信息,则确定建立了第二连接。
另外,为了实现通过第一定时器和第二定时器检测连接操作是否失败,在在本公开实施例中,上述配置信息还包括第一定时器的第一定时阈值和第二定时器的第二定时阈值;
相应的,上述基于第一定时器的计时结果检测第一连接操作是否失败,包括:根据第一定时阈值判断第一定时器是否超时;若是,则确定第一连接操作失败;
相应的,上述基于第二定时器的计时结果检测第二连接操作是否失败,包括:根据第二定时阈值判断第二定时器是否超时;若是,则确定第二连接操作失败。
在具体实施时,可以是将第一定时器的计时结果与第一定时阈值进行比较,若是第一定时器的计时结果大于或等于第一定时阈值,则确定第一定时器超时;将第二定时器的计时结果与第二定时阈值进行比较,若是第二定时器的计时结果大于或等于第二定时阈值,则确定第二定时器超时。
当然,上述只是列举了判断第一定时器、第二定时器是否超时的一种具体实现方式,而判断第一定时器、第二定时器是否超时的具体实现方式并不局限于此,还可以通过其他方式实现,此处不再一一赘述。
为便于理解,下述将以检测第一连接操作是否失败为例详细介绍本公开实施例提供的方法中检测操作失败的具体过程。
图3示出了本公开实施例中,在移动性过程中检测第一连接操作是否失败的方法流程图,图3所示的方法,至少包括如下步骤:
步骤202,在处于移动性过程中时,基于第一连接配置信息执行第一连接操作时并启动第一定时器。
步骤204,判断是否建立了第一连接操作;若是,则执行步骤206。
步骤206,停止第一定时器。
步骤208,根据第一定时阈值判断第一定时器是否超时;若是,则执行步骤210。
步骤210,确定第一连接操作失败。
其中,上述第一定时阈值为网络侧设备配置的。
在本公开实施例中,通过第一定时器对第一连接操作进行计时,通过第二定时器对第二连接操作进行计时,并根据第一定时器和第二定时器的计时时长分别检测第一连接操作和第二连接操作是否失败,实现过程简单方便,可以方便、快捷的检测出第一连接操作和第二连接操作是否出现由于定时器超时而出现的失败,便于后续针对该种失败类型对第一连接操作和第二连接操作执行相应的处理过程。
方式二,
通过第一定时器对第一连接配置信息所对应的第一连接操作进行计时,基于第一定时器的计时结果检测第一连接操作是否失败;通过第二定时器对第一连接配置信息所对应的第一连接操作以及第二连接配置信息所对应的第二连接操作进行计时,基于第二定时器的计时结果检测第二连接操作是否失败。
具体的,在该种方式下,通过第一定时器对第一连接配置信息所对应的第一连接操作进行计时,以及基于第一定时器的计时结果检测第一连接操作 是否失败的具体过程与上述第一种情况相同,可参考上述第一种情况的详细介绍,此处不再赘述。
需要说明的是,在该种方式下,第二定时器所计时的时长为第一连接操作和第二连接操作的总连接时长。
相应的,上述通过第二定时器对第一连接配置信息所对应的第一连接操作和第二连接配置信息所对应的第二连接操作进行计时,具体包括如下过程:
在基于第一连接配置信息执行第一连接操作时,启动第一定时器;当建立第二连接时,停止第二定时器。
将第二定时器从启动时刻到停止时刻的时长,确定为第二定时器的定时结果;其中,第二定时器的时长用于表示第一连接操作和第二连接操作所对应的总连接时长。
其中,在该种方式下,判断是否建立了第二连接操作的具体过程与第一种情况中相同,此处不再赘述。
另外,由于在该种方式下,第二定时器的计时时长为第一连接操作和第二连接操作对应的总连接时长。网络侧设备发送的配置信息中第二定时器所对应的定时阈值的具体大小不同于上述方式一种的第二定时阈值,为了进行区分,在该种方式下,第二定时器所对应的定时阈值记为第三定时阈值。
相应的,上述基于第二定时器的计时结果检测第二连接操作是否失败,包括:
根据第三定时阈值判断第二定时器是否超时;若是,则确定第二连接操作失败。
为便于理解该种方式下检测第一连接操作和第二连接操作是否失败的具体实现过程,下述将通过具体实施例进行说明。
图4为本公开实施例中检测连接操作是否失败的方法流程图,图4所示的方法至少包括如下步骤:
步骤302,处于移动性过程中时,基于第一连接配置信息执行第一连接操作并启动第一定时器和第二定时器;
步骤304,判断是否建立了第一连接操作;若是,则执行步骤306;
步骤306,停止第一定时器。
步骤308,根据第一定时阈值判断第一定时器是否超时;若是,则执行步骤310。
步骤310,确定第一连接操作失败。
步骤312,基于第二连接配置信息执行第二连接操作。
步骤314,判断是否建立了第二连接操作;若是,则执行步骤316。
步骤316,停止第二定时器。
步骤318,根据第三定时阈值判断第二定时器是否超时;若是,则执行步骤320。
步骤320,确定第二连接操作失败。
需要说明的是,上述第一定时阈值和第三定时阈值均为网络侧设备配置的。
在本公开实施例中,在通过第一定时器和第二定时器检测连接操作是否失败时,在基于第一连接配置信息建立第一连接操作时,启动第一定时器和第二定时器,并在建立了第一连接操作时,停止第一定时器,在建立了第二连接操作时,停止第二定时器;避免了在基于第二连接配置信息建立第二连接操作时,再启动第二定时器,在一个触发时刻同时启动两个定时器,使得检测过程更加方便,因此可以简单、方便的检测是否由于定时器超时而导致连接操作失败。
上述介绍的为通过定时器检测是否出现由于定时器超时而导致的连接操作失败,相应的,若是检测到第一连接操作失败,则步骤106中执行失败的连接操作所对应的处理过程,则为执行第一连接操作失败所对应的处理过程,具体可以包括以下A1~A6处理过程中的至少一种:
A1、向网络侧设备上报失败信息;其中,上述失败信息至少包括以下信息:第一连接操作失败的类型;源节点小区、目标节点小区和邻小区中至少一个小区的测量信息;

A4、将终端设备的连接状态恢复至执行连接操作之前的连接状态;
A5、停止或挂起终端设备与源节点的连接;
A6、重置或重建终端设备与源节点的连接实体。
具体的,在上述A1中,上述第一连接操作失败的类型则为第一定时器超时导致的连接失败。在该种情况下,可以通过与源节点的连接将失败信息上报给网络侧设备。当网络侧设备接收到终端设备上报的第一连接操作失败的失败信息后,向终端设备发送连接重配置信息,以使终端设备与当前可建立连接的节点建立连接。
在上述A4中,将终端设备的连接状态恢复至执行连接操作之前的连接状态,可以理解为,将终端设备的连接状态恢复至执行第一连接操作之前的连接状态。即在执行第一连接操作之前终端设备与哪些节点建立了连接,则使终端设备仍然保持与上述节点的连接即可。
在上述A5中,停止或挂起终端设备与源节点的连接,则是停止通过与源节点的连接进行数据的接收和发送。
在上述A6中,重置或重建终端设备与源节点的连接实体可以是终端设备与源节点连接的MAC/RLC/PDCP/SDAP实体。
另外,若是检测到第二连接操作失败,则步骤106中执行失败的连接操作所对应的处理过程,则为执行第二连接操作失败所对应的处理过程,具体可以包括以下B1~B3处理过程中的至少一种:
B1、重建立终端设备与网络侧设备之间的RRC连接;
B2、将终端设备的连接状态恢复至执行连接操作之前的连接状态;
B3、向网络侧设备上报失败信息;其中,上述失败信息至少包括以下信息:第二连接操作失败的类型;源节点小区、目标节点小区和邻小区中至少一个小区的测量信息。
其中,在上述B2中,将终端设备的连接状态恢复至执行连接操作之前的连接状态,可以理解为,将终端设备的连接状态恢复至执行第一连接操作之前的连接状态。即在执行第一连接操作之前终端设备与哪些节点建立了连接,则使终端设备仍然保持与上述节点的连接即可。
在上述B3中,第二连接操作失败的类型则为第二定时器超时导致的失败。在一种具体实现方式中,可以在执行完上述B1的处理过程后,向网络侧设备上报失败信息。具体的,当网络侧设备接收到终端设备上报的第一连接操作 失败的失败信息后,向终端设备发送连接重配置信息,以使终端设备与当前可建立连接的节点建立连接。
当然,在本公开实施例中,除了通过定时器检测是否出现由于定时器超时而导致的连接失败,上述步骤104中,检测配置信息所对应的连接操作是否失败还可以包括以下S1-S7检测方式中的至少一种:
S1、若检测到上述连接的物理层失步,则确定上述配置信息所对应的连接操作失败;
S2、若检测到上述连接的MAC层的随机接入达到最大发送次数,则确定上述配置信息所对应的连接操作失败;
S3、若检测到上述终端设备的数据传输次数达到上述连接的RLC实体的最大重传次数,则确定上述配置信息所对应的连接操作失败;
S4、若检测到上述连接的RRC消息重配置失败,则确定上述配置信息所对应的连接操作失败;
S5、若检测到上述终端设备的波束恢复过程失败,则确定上述配置信息所对应的连接操作失败;
S6、若检测到PDCP实体的MAC-I错误,则确定上述配置信息所对应的连接操作失败;
S7、若检测到上述终端设备的主小区组和辅小区组之间的上行传输的子帧边界的差值超出最大上行传输定时差,则确定上述配置信息所对应的连接操作失败。
具体的,若是使用上述S1-S7中的一种或者多种的组合检测第一连接操作是否失败,在S1-S7中所提及到的连接则为第一连接,若是使用上述S1-S7中的一种或者多种的组合检测第二连接操作是否失败,在S1-S7中所提及到的连接则为第二连接。
下述将以检测第一连接操作是否失败为例,详细介绍上述S1-S7中各种方法的具体实现过程。
其中,在S1中则检测第一连接的物理层是否失步,若是检测到第一连接的物理层失步,则确定第一连接操作失败。具体的,在本公开实施例中,可以通过检测定时器T310是否超时来检测第一连接的物理层是否失步,若是定 时器T310超时,则确定第一连接的物理层失步。
在S2所示方式中,则是在执行第一连接操作的过程中,检测第一连接的MAC层的随机接入的次数,并判断该随机接入的次数是否达到最大发送次数(该最大发送次数可以理解为最大尝试次数),若是,则确定第一连接操作失败。
在S3所示方式中,则是在执行第一连接操作的过程中,检测终端设备的数据传输次数,并判断该数据传输次数是否达到第一连接的RLC实体的最大重传次数,若是,则确定第一连接操作失败。
在S4所示方式中,则是检测第一连接的RRC消息是否重配置失败,若是检测到RRC消息重配置失败,则确定第一连接操作失败。

在C2中,则是继续进行切换或者添加、改变SCG,可以从基于第一连接配置信息执行第一连接操作重新开始。
在C5中,将所述终端设备的连接状态恢复至执行连接操作之前的连接状态,可以为将终端设备的连接配置回退到执行第一连接操作之前终端设备的配置。即在执行第一连接操作之前终端设备与哪些节点建立了连接,则使终端设备仍然保持与上述节点的连接即可。
