Description

通信方法、用户设备、基站及非暂态电脑可读取存储媒体 【技术领域】
本申请涉及通信领域，尤其涉及一种通信方法、用户设备、基站及非暂态电脑可读取存储媒体。
【背景技术】
当用户设备(例如手机)开机后，通过4G网络与一基站(为方便描述，称为第一基站)连接，该基站通过4G网络向用户设备发送指令，使得用户设备搜索5G信号。用户设备搜索到5G信号之后，上报给第一基站，第一基站向用户设备发送指令，使得用户设备通过5G网络与第二基站连接。这样，用户设备同时能够使用4G网络和5G网络，也就是所谓的双连接(Dual Connectivity)。
基站在需要发起对无线承揽(Radio Bearer)进行管理、底层参数配置、切换执行或测量控制时，会触发RRC连接重配置过程。当第一基站向用户设备发送RRC重配置消息，且用户设备成功接收重配置消息后，用户设备会分别对4G网络和5G网络进行重配置。
当用户设备与基站之间的5G网络信号差或无线链路失败的时候，如果用户设备又接收到第一基站发送的连接重配置消息，将无法完成对5G网络的重配置。由于用户设备无法执行连接重配置消息中的内容，进一步触发连接重建过程，使得4G网络也随之暂停，从而影响用户设备的数据传输与用户体验。基站不知道用户设备与基站之间5G网络失败的状况，仅能持续等待用户设备发送重配置完成消息，或是再次向用户设备发送重配置消息，或是仅接收到用户设备的连接重建请求却无从得知用户设备进行连接重建的原因，无法优化网络。

图1A中存在一个基站，为方便描述，将该基站称为第一基站(基站11)，用户设备20与第一基站通过第一无线链路L1和第二无线链路L2连接。
图1B中存在两个基站，为方便描述，将这两个基站称为第一基站和第二基站(基站11表示第一基站，基站12表示第二基站)，用户设备20与第一基站通过第一无线链路L1连接，与第二基站通过第二无线链路L2连接。
在本申请实施例中，第一无线链路可以为4G网络，或称为长期演进(LTE，Long Term Evolution)网络。第二无线链路可以为5G网络，或称为新无线电(NR，New Radio)网络。用户设备20通过第一无线链路L1和第二无线链路L2连接的基站，可以是同时提供第一无线链路L1和第二无线链路L2的同一个基站，例如图1中所示出的第一基站(基站11)；也可以是第一基站(基站11)提供第一无线链路L1，第二基站(基站12)提供第二无线链路L2。第一基站与第二基站可以是物理上不同的两个基站(如图2所示)，也可以是以功能区分的、实际上提供不同无线链路功能的同一个基站(如图1所示)，本申请的基站不以前述为限定。
执行本申请实施例提供的通信方法的基站为第一基站，如果没有特别指出，下文所述的基站均指的是第一基站。
请参见图2，所示为本申请第二实施例提供的一种通信方法，该方法包括以下步骤：
步骤S202：基站向用户设备发送连接重配置消息。
步骤S204：若存在已经启动的辅小区组失败信息过程，用户设备接收连接重配置消息。
当用户设备的无线链路发生辅小区组失败的情况时，也就是用户设备与基站之间的第二无线链路失败，用户设备启动辅小区组失败信息过程，以向基站上报用户设备所经历的辅小区组失败。造成辅小区组失败的原因有多种，例如辅小区组无线链路失败、辅小区组同步重配置失败、或者SRB3上RRC消息的辅小区组配置失败和辅小区组完整性检查失败。
步骤S204中，可以先判断用户设备是否存在已经启动的辅小区组失败信息过程，再判断用户设备是否接收到连接重配置消息；也可以先判断用户设备是否接收到连接重配置消息，再判断用户设备是否存在已经启动的辅小区组失败信息过程，两个判断过程的先后不做限定。
步骤S206：用户设备发送第一消息至基站。第一消息包含第二无线链路失败信息。
作为第一种可选的实施方式，第一消息是第二无线链路辅小区组失败消息。
作为第二种可选的实施方式，第一消息包括第二无线链路辅小区组失败消息和连接重建请求消息。
作为第三种可选的实施方式，第一消息是连接重建请求消息，连接重建请求消息的重建原因包含第二无线链路失败信息。
上述三种实施方式独立实施，至于采用哪一种实施方式，可以根据需求或是基站提供给用户设备的资源分配相关信息来决定。如果基站分配给用户设备的上行调度(UL grant)具有足够的资源块(Resource Block)，则可以采用上述第二种实施方式。如果基站分配给用户设备的上行调度的资源块较少，则可以采用上述第一种实施方式或第三种实施方式。
无论采用上述哪一种实施方式，当基站接收到第一消息之后，由于第一消息包含第二无线链路失败信息，因此，基站即可知道用户设备与基站之间的第二无线链路失败，并进行对应的调整或适配。
步骤S208：基站接收第一消息。
作为一种可选的实施方式，在基站接收第一消息之后，基站向用户设备发送消息，该消息包含释放第二无线链路的信息，用户设备接收该消息后，释放第二无线链路。
请参见图3A，所示为本申请第三实施例提供的用户设备与基站之间交互的示意图。本实施例中用户设备与基站之间交互包括以下步骤：
步骤S301：基站向用户设备发送连接重配置消息。
步骤S302：若用户设备存在已经启动的辅小区组失败信息过程，用户设备接收连接重配置消息。
步骤S303：用户设备忽略连接重配置消息。
步骤S304：用户设备向基站发送第二无线链路辅小区组失败消息。
在第一无线链路和第二无线链路均正常的情况下，当用户设备接收到连接重配置消息之后，会根据连接重配置消息对第一无线链路和第二无线链路进行重配置。配置完成后，用户设备发送连接重配置完成消息至基站。此时基站就知道用户设备完成配置。否则，基站会认为用户设备没有接收到连接重配置消息，从而不断向用户设备发送连接重配置消息。
在本实施例中，由于用户设备与基站之间的第二无线链路失败，当用户设备接收连接重配置消息之后，无法对第二无线链路进行重配置。用户设备忽略连接重配置消息，也就是不会根据连接重配置消息对第一无线链路和第二无线链路进行重配置。然后，基站收到用户设备发送的第二无线链路辅小区组失败消息，会知道用户设备与基站之间的第二无线链路失败。基站再发出的连接重配置消息将会排除重配置该失败的第二无线链路。
当基站等待过久没有收到用户设备发送的连接重配置完成消息、连接重建请求消息或是第二无线链路辅小区组失败消息，基站可能会再次对用户终端发出连接重配置消息。若此时用户设备与基站之间的第二无线链路仍然失败，则用户设备就会再 次忽略该连接重配置消息，并且再次向基站发送第二无线链路辅小区组失败消息。
在本实施例中，步骤S303与步骤S304的执行顺序可以对调。在步骤S302之后，可以先执行步骤S304再执行步骤S303。
请参见图3B，所示为本申请第四实施例提供的用户设备与基站之间交互的示意图。在图3B中，只有步骤S303’与图3A中的步骤S303不同，其余步骤均对应相同。本实施例中用户设备与基站之间交互包括以下步骤：
步骤S301：基站向用户设备发送连接重配置消息。
步骤S302：若用户设备存在已经启动的辅小区组失败信息过程，用户设备接收连接重配置消息。
步骤S303’：用户设备向基站发送连接重配置完成消息。
步骤S304：用户设备向基站发送第二无线链路辅小区组失败消息。
在本实施例中，步骤S304可以在步骤S303’之后执行，也可以步骤S304在步骤S303’之前执行，或是与步骤S303’同时执行。如果基站分配给用户设备的上行调度的资源块较少，步骤S304可以在步骤S303’之后执行，即，用户设备先向基站发送连接重配置完成消息，再向基站发送第二无线链路辅小区组失败消息。如果基站分配给用户设备的上行调度的资源块较少，步骤S304也可以在步骤S303’之前执行，即，用户设备先向基站发送第二无线链路辅小区组失败消息，再向基站发送连接重配置完成消息。如果基站分配给用户设备足够的上行调度(UL grant)的资源块，则步骤S304与步骤S303’可以同时执行，即，用户设备同时向基站发送第二无线链路辅小区组失败消息和连接重配置完成消息。
在本实施例中，用户设备可以根据连接重配置消息只完成第一无线链路的重配置，基站可以根据连接重配置完成消息和第二无线链路辅小区组失败消息，判断出用户设备仅采用部分的连接重配置消息。在另一种可选的实施方式中，用户设备也可以不对第一无线链路重配置。
在本实施例中，基站收到用户设备发送的连接重配置完成消息和第二无线链路辅小区组失败消息，会推测或知道用户设备仅采用部分的连接重配置消息以及用户设备与基站之间的第二无线链路失败。基站再发出的连接重配置消息将会排除重配置该失败的第二无线链路。
在本实施例中，用户设备发送的连接重配置完成消息还可以不包括第二无线链路辅小区组配置响应。基站收到用户设备发送的连接重配置完成消息时，会知道第二无线链路的重配置并未得到确认。
在前述的图3A与图3B所示的实施例中，用户设备通过忽略连接重配置消息或是发送连接重配置完成消息的方法，避免进入连接重建过程，从而正常的第一无线链路不会因为第二无线链路失败引起的连接重建过程而受到影响。此外，用户设备通过向基站发送第二无线链路失败信息，让基站知道第二无线链路失败并进一步执行网络优化过程。由于用户设备对于失败的无线链路不进行无效的重配置，用户设备可以避免功耗浪费并达到省电效果。
请参见图3C，所示为本申请第五实施例提供的用户设备与基站之间交互的示意图。在图3C中，与图3A相同标号的步骤均相同。与图3A相比较，图3C中不包含步骤S303，并且增加步骤S306。本实施例中用户设备与基站之间交互包括以下步骤：
步骤S301：基站向用户设备发送连接重配置消息。
步骤S302：若用户设备存在已经启动的辅小区组失败信息过程，用户设备接收连接重配置消息。
步骤S304：用户设备向基站发送第二无线链路辅小区组失败消息。
步骤S306：执行连接重建过程。
连接重建过程涉及用户设备与基站的交互。在本实施例中，步骤S306的连接重建过程具体包括以下步骤：
步骤S306a：用户设备向基站发送消息1(MSG1)，其中消息1包括前导码(Preamble)。
步骤S306b：基站向用户设备发送消息2(MSG2)，其中消息2包括随机接入响应消息。
在步骤S306b中，用户通过基站提供的随机接入响应消息取得基站分配的上行调度(UL grant)。
步骤S306c：用户设备向基站发送消息3(MSG3)，其中消息3包括连接重建请求消息。
步骤S306d：基站向用户设备发送消息4(MSG4)。
在本实施例中，步骤S306在步骤S304之后执行。由于用户设备与基站之间的第二无线链路失败，当用户设备接收连接重配置消息之后，无法对第二无线链路进行重配置，并且执行连接重建过程。因此用户设备先向基站发送第二无线链路辅小区组失败消息，再执行连接重建过程并且释放第二无线链路。然后，基站会知道用户设备与基站之间的第二无线链路失败，并进一步执行网络优化过程。基站再发出的连接重配置消息将会排除重配置该失败的第二无线链路。用户设备释放失败的无线链路，并且不再进行无效的重配置，用户设备可以避免功耗浪费并达到省电效果。
在本实施例中，步骤S304与步骤S306的执行顺序可以对调。在步骤S302之后，可以先执行步骤S306再执行步骤S304。也就是说，用户设备可以先执行连接重建过程，再向基站发送第二无线链路辅小区组失败消息。用户设备可以通过此种方式取得基站分配的上行调度，以获得发送第二无线链路辅小区组失败消息至基站的上行资源。
请参见图3D，所示为本申请第六实施例提供的用户设备与基站之间交互的示意图。在图3D中，与图3C相同标号的步骤均相同。与图3C相比较，本实施例中不包含步骤S304，并且步骤S306c’与图3C中的步骤S306c不同。本实施例中用户设备与基站之间交互包括以下步骤：
步骤S301：基站向用户设备发送连接重配置消息。
步骤S302：若用户设备存在已经启动的辅小区组失败信息过程，用户设备接收连接重配置消息。
步骤S306：执行连接重建过程。
连接重建过程涉及用户设备与基站的交互。在本实施例中，步骤S306的连接重建过程具体包括以下步骤：
步骤S306a：用户设备向基站发送消息1(MSG1)，其中消息1包括前导码(Preamble)。
步骤S306b：基站向用户设备发送消息2(MSG2)，其中消息2包括随机接入响应消息。
在步骤S306b中，用户通过基站提供的随机接入响应消息取得基站分配的上行调度(UL grant)。
步骤S306c’：用户设备向基站发送消息3(MSG3)，消息3包括连接重建请求消息和第二无线链路失败信息。
步骤S306d：基站向用户设备发送消息4(MSG4)。
在本实施例中，步骤S306在步骤S302之后执行。如果基站分配给用户设备足够的上行调度(UL grant)的资源块，则用户设备可以在步骤S306c’中同时发送第二无线链路辅小区组失败消息和连接重建请求消息，第二无线链路失败信息此时以第二无线链路辅小区组失败消息的方式存在。如果基站分配给用户设备的上行调度的资源块较少，消息3的连接重建请求消息的重建原因可以包含第二无线链路失败信息，第二无线链路失败信息此时以重建原因的方式存在。因此，用户设备可以通过在连接重建过程的消息3中发送第二无线链路失败信息以通知基站第二无线链路失败，从而减少发送消息的次数。基站也能够通过消息3了解用户设备连接重建的原因以及第二无线链路失败并进一步执行网络优化过程。基站再发出的连接重配置消息也将会排除重配置该失败的第二无线链路，以避免用户设备对于失败的无线链路进行无效的重配置，用户设备可以减少功耗浪费并达到省电效果。
请参见图3E，所示为本申请第七实施例提供的用户设备与基站之间交互的示意图。在图3E中，与图3D相同标号的步骤均相同，本实施例中增加步骤S305。本实施例中用户设备与基站之间交互包括以下步骤：
步骤S301：基站向用户设备发送连接重配置消息。
步骤S302：若用户设备存在已经启动的辅小区组失败信息过程，用户设备接收连接重配置消息。
步骤S305：用户设备取消执行辅小区组失败信息过程。
步骤S306：执行连接重建过程。
连接重建过程涉及用户设备与基站的交互。在本实施例中，步骤S305在步骤S302之后执行。用户设备在启动辅小区组失败信息过程之后，又收到基站发出的连接重配置消息。由于第二无线链路失败造成用户设备无法重配置第二无线链路，进而触发连接重建过程。此时，由于消息3包括第二无线链路失败信息，该信息可以是第二无线链路辅小区组失败消息，或是以重建原因的形式存在。因此用户设备可以取消执行辅小区组失败信息过程，从而不重复发送带有第二无线链路失败信息的消息。 用户设备还可以通过在连接重建过程中发送第二无线链路失败信息以通知基站第二无线链路失败，从而减少发送消息的次数。
在本实施例中另一种方案是，步骤S306中用户设备向基站发送的消息3(MSG3)，可以是包括连接重建请求消息，而不包括第二无线链路失败信息。用户设备可以是仅取消执行辅小区组失败信息过程，而不发送带有第二无线链路失败信息的消息，以节省上行调度的资源块。在基站分配给用户设备的上行调度的资源块较少的场景中，本实施例的此种方案可以减少发送消息的次数，节省上行调度资源。
在本实施例中，步骤S305与步骤S306的执行顺序可以对调。在步骤S302之后，可以先执行步骤S306再执行步骤S305。
在前述的图3C、图3D与图3E所示的实施例中，步骤S306d的消息4可以进一步包括释放第二无线链路的信息内容。若是用户设备在开始连接重建过程时，没有成功释放第二无线链路，此种可选择的实施方式可以再次确保用户设备能够释放第二无线链路。这样可以避免用户设备一直尝试重配置或是尝试通过第二无线链路连接基站而造成的耗电。用户设备能够减少发送消息的次数达到省电的效果，或是控制与第二无线链路相关的硬件模块关闭或待机以节省功耗。此外，用户设备还能够向基站发送第二无线链路失败信息，让基站知道第二无线链路失败并进一步执行网络优化过程。
请参见图4，所示为本申请第八实施例提供的一种通信方法，该方法包括以下步骤：
步骤S402：基站向用户设备发送连接重配置消息。
步骤S404：若存在已经启动的辅小区组失败信息过程，用户设备接收连接重配置消息。
当用户设备的无线链路发生辅小区组失败的情况时，也就是用户设备与基站之间的第二无线链路失败，用户设备启动辅小区组失败信息过程，以向基站上报用户设备所经历的辅小区组失败。造成辅小区组失败的原因有多种，例如辅小区组无线链路失败、辅小区组同步重配置失败、或者SRB3上RRC消息的辅小区组配置失败和辅小区组完整性检查失败。
步骤S404中，可以先判断用户设备是否存在已经启动的辅小区组失败信息过程， 再判断用户设备是否接收到连接重配置消息；也可以先判断用户设备是否接收到连接重配置消息，再判断用户设备是否存在已经启动的辅小区组失败信息过程，两个判断过程的先后不做限定。
步骤S406：用户设备触发随机接入过程。在所述随机接入过程中，用户设备发送第二消息至所述基站，所述第二消息包含第二无线链路失败信息。
作为第一种可选的实施方式，第二消息是第二无线链路辅小区组失败消息。
作为第二种可选的实施方式，第二消息包括第二无线链路辅小区组失败消息和连接重建请求消息。
作为第三种可选的实施方式，第二消息是连接重建请求消息，连接重建请求消息的重建原因包含第二无线链路失败信息。
至于采用上述哪一种实施方式，可以根据过程需求或是基站提供给用户设备的资源分配相关信息来决定。如果基站分配给用户设备的上行调度(UL grant)具有足够的资源块(Resource Block)，则可以采用上述第二种实施方式。如果基站分配给用户设备的上行调度的资源块较少，则可以采用上述第一种实施方式或第三种实施方式。
无论采用上述哪一种实施方式，当基站接收到第二消息之后，由于第二消息包含第二无线链路失败信息，因此，基站即可知道用户设备与基站之间的第二无线链路失败，并进行对应的调整或适配。
步骤S408：基站接收第二消息。
作为一种可选的实施方式，在步骤S408：基站接收第二消息之后，基站向用户设备发送消息，该消息包含释放第二无线链路的信息，用户设备接收该消息后，释放第二无线链路。
请参见图5A，所示为本申请第九实施例提供的用户设备与基站之间交互的示意图。本实施例中用户设备与基站之间交互包括以下步骤：
步骤S501：基站向用户设备发送连接重配置消息。
步骤S502：若用户设备存在已经启动的辅小区组失败信息过程，用户设备接收连接重配置消息。
当用户设备的无线链路发生辅小区组失败的情况时，也就是用户设备与基站之 间的第二无线链路失败，用户设备启动辅小区组失败信息过程，以向基站上报用户设备所经历的辅小区组失败。造成辅小区组失败的原因有多种，例如辅小区组无线链路失败、辅小区组同步重配置失败、或者SRB3上RRC消息的辅小区组配置失败和辅小区组完整性检查失败。
在步骤S502中，可以先判断用户设备是否存在已经启动的辅小区组失败信息过程，再判断用户设备是否接收到连接重配置消息；也可以先判断用户设备是否接收到连接重配置消息，再判断用户设备是否存在已经启动的辅小区组失败信息过程，两个判断过程的先后不做限定。
在步骤S502后，用户设备触发随机接入过程。随机接入过程(步骤S505)具体包括以下步骤：
步骤S505a：用户设备向基站发送消息1(MSG1)，其中消息1包括前导码(Preamble)。
步骤S505b：基站向用户设备发送消息2(MSG2)，其中消息2包括随机接入响应消息。
步骤S505c：用户设备向基站发送消息3(MSG3)，其中消息3包括第二无线链路辅小区组失败消息。
步骤S505d：基站发送消息4(MSG4)到用户设备，其中消息4包括释放第二无线链路的信息。
在步骤S505后，作为一种可选的实施方式，用户设备接收到消息4后，释放第二无线链路。
在本实施例中，步骤S505在步骤S502之后执行。由于用户设备与基站之间的第二无线链路失败，当用户设备接收连接重配置消息之后，无法对第二无线链路进行重配置。此时用户设备需要向基站发送第二无线链路失败信息，例如第二无线链路辅小区组失败消息。在随机接入过程中，用户通过基站提供的随机接入响应消息取得基站分配的上行调度(UL grant)并且得以发送第二无线链路辅小区组失败消息。使得基站知道用户设备与基站之间的第二无线链路失败，并进一步执行网络优化过程。基站再发出的连接重配置消息将会排除重配置该失败的第二无线链路。用户设备释放失败的无线链路，并且不再进行无效的重配置，如此用户设备可以避免功耗浪费并达到省电效果。
请参见图5B，所示为本申请第十实施例提供的用户设备与基站之间交互的示意图。在图5B中，与图5A相同标号的步骤均相同。与图5A相比较，增加步骤S503。本实施例中用户设备与基站之间交互包括以下步骤：
步骤S501：基站向用户设备发送连接重配置消息。
步骤S502：若用户设备存在已经启动的辅小区组失败信息过程，用户设备接收连接重配置消息。
步骤S503：用户设备判断是否缺乏上行链路资源。
若步骤S503中用户设备判断出缺乏上行链路资源，则用户设备触发随机接入过程。随机接入过程(步骤S505)具体包括步骤S505a至步骤S505d，于此不再重复叙述。
在本实施例中，当用户设备缺乏上行链路资源时，通过触发随机接入过程以取得基站分配的上行调度(UL grant)。用户设备还能够利用随机接入过程中的消息3发送第二无线链路辅小区组失败消息。用户设备可以利用在随机接入过程中消息3发送第二无线链路失败信息以通知基站第二无线链路失败，从而减少发送消息的次数。
请参见图5C，所示为本申请第十一实施例提供的用户设备与基站之间交互的示意图。在图5C中，与图5A相同标号的步骤均相同。与图5A相比较，本实施例中增加步骤S504和步骤S506。本实施例中用户设备与基站之间交互包括以下步骤：
步骤S501：基站向用户设备发送连接重配置消息。
步骤S502：若用户设备存在已经启动的辅小区组失败信息过程，用户设备接收连接重配置消息。
步骤S504：用户设备判断第一计时器的数值是否达到默认阈值。
第一计时器自辅小区组失败信息过程启动开始计时，默认阈值可以是预先设置的阈值，也可以是通过第一无线链路取得的阈值。若第一计时器的数值达到默认阈值，则触发随机接入过程。在另一种可选的实施方式中，若第一计时器的数值达到默认阈值且用户设备尚未发送第二无线链路辅小区组失败消息，则触发随机接入过程。
随机接入过程(步骤S505)具体包括步骤S505a至步骤S505d，于此不再重复叙述。
步骤S506：用户设备停止第一计时器的计时。
在本实施例中，步骤S504在步骤S502之后执行，步骤S506可以在步骤S505c或S505d之后执行。用户设备可以通过第一无线链路取得基站分配的第一计时器。用户设备也可以在发出消息3或者收到消息4之后，停止第一计时器的计时。用户设备可以通过采用第一计时器，来避免过度等待上行链路资源，并减少功耗浪费达到省电效果。
请参见图5D，所示为本申请第十二实施例提供的用户设备与基站之间交互的示意图。在图5D中，与图5A相同标号的步骤均相同。与图5A相比较，本实施例中增加步骤S507。本实施例中用户设备与基站之间交互包括以下步骤：
步骤S501：基站向用户设备发送连接重配置消息。
步骤S502：若用户设备存在已经启动的辅小区组失败信息过程，用户设备接收连接重配置消息。
在步骤S502后，用户设备触发随机接入过程。随机接入过程(步骤S505)具体包括步骤S505a至步骤S505d，于此不再重复叙述。
步骤S507：执行连接重建过程。
在本实施例中，步骤S507在步骤S505之后执行。连接重建过程包括以下几个步骤：
第一步：用户设备向基站发送消息1，其中消息1包括前导码。
第二步：基站向用户设备发送消息2，其中消息2包括随机接入响应消息。
第三步：用户设备向基站发送消息3，其中消息3包括连接重建请求消息。
第四步：基站向用户设备发送消息4。
在本实施例中，由于用户设备与基站之间的第二无线链路失败，当用户设备接收连接重配置消息之后，无法对第二无线链路进行重配置，并且将执行连接重建过程。因此用户设备先向基站发送第二无线链路辅小区组失败消息，再执行连接重建过程。如此基站能够了解第二无线链路失败以及用户设备连接重建的原因，并进一步执行网络优化过程。基站再发出的连接重配置消息也将会排除重配置该失败的无线链路，以避免用户设备进行无效的重配置，用户设备可以减少功耗浪费并达到省电效果。
请参见图5E，所示为本申请第十三实施例提供的用户设备与基站之间交互的示意图。在图5E中，与图5A相同标号的步骤均相同。与图5A相比较，增加步骤S503、步骤S504、步骤S506和步骤S507。图5E中的步骤S503与图5B的步骤S503相同。步骤S504与步骤S506相同于图5C的步骤S504与步骤S506。图5E中的步骤S507与图5D的步骤S507相同。各个步骤的详细内容与此不再重复描述。本实施例中用户设备与基站之间交互包括以下步骤：

步骤S506：用户设备停止第一计时器的计时。
步骤S507：执行连接重建过程。
请参见图6，所示为本申请第十四实施例提供的一种通信方法，该方法包括以下步骤：
步骤S602：启动辅小区组失败信息过程时，用户设备触发随机接入过程。在随机接入过程中，用户设备将第五消息发送至基站。第五消息包含第二无线链路失败信 息。
当用户设备的无线链路发生辅小区组失败的情况时，也就是用户设备与基站之间的第二无线链路失败，用户设备启动辅小区组失败信息过程，以向基站上报用户设备所经历的辅小区组失败。造成辅小区组失败的原因有多种，例如辅小区组无线链路失败、辅小区组同步重配置失败、或者SRB3上RRC消息的辅小区组配置失败和辅小区组完整性检查失败。
步骤S604：基站接收第五消息。
作为一种可选的实施方式，用户设备触发随机接入过程之前，若接收连接重配置消息，则忽略连接重配置消息或是发送连接重配置完成消息至基站。作为另一种可选的实施方式，在基站接收第一消息之后，基站向用户设备发送消息，该消息包含释放第二无线链路的信息。用户设备接收该消息后，释放第二无线链路。

步骤S701：用户设备启动辅小区组失败信息过程。
步骤S702：用户设备判断第一计时器的数值是否达到默认阈值。
第一计时器自辅小区组失败信息过程启动开始计时，默认阈值可以是预先设置的阈值，也可以是通过第一无线链路取得的阈值。若第一计时器的数值达到默认阈值，则触发随机接入过程。在另一种可选的实施方式中，若第一计时器的数值达到默认阈值且用户设备尚未发送第二无线链路辅小区组失败消息，则触发随机接入过程。
在步骤S702后，用户设备触发随机接入过程。随机接入过程(步骤S703)具体包括步骤S703a至步骤S703d，于此不再重复叙述。
步骤S704：用户设备停止第一计时器的计时。
步骤S705：用户设备释放第二无线链路。
在本实施例中，步骤S704可以在步骤S703c或S703d之后执行。用户设备可以通过第一无线链路取得基站分配的第一计时器。用户设备也可以在发出消息3或者收到消息4之后，停止第一计时器的计时。用户设备可以通过采用第一计时器，来避免过度等待上行链路资源，并减少功耗浪费达到省电效果。
请参见图7C，所示为本申请第十七实施例提供的用户设备与基站之间交互的示意图。在图7C中，与图7A相同标号的步骤均相同。本实施例中用户设备与基站之间交互包括以下步骤：

步骤S706：用户设备释放第二无线链路。
在步骤S706中，用户设备释放第二无线链路可以进一步包括执行连接重建过程，用户设备通过触发连接重建过程来释放第二无线链路。连接重建过程的步骤与前述图5D的步骤S507的连接重建过程相同，于此不再重复叙述。
在图6、图7A、图7B与图7C的实施例中，由于用户设备与基站之间的第二无线链路失败，当用户设备接收连接重配置消息之后，无法对第二无线链路进行重配 置。此时用户设备需要向基站发送第二无线链路失败信息，例如第二无线链路辅小区组失败消息。在随机接入过程中，用户通过基站提供的随机接入响应消息取得基站分配的上行调度(UL grant)并且得以发送第二无线链路辅小区组失败消息，使得基站得以知道用户设备与基站之间的第二无线链路失败，并进一步执行网络优化过程。基站再发出的连接重配置消息将会排除重配置该失败的第二无线链路。用户设备释放失败的无线链路，并且不再进行无效的重配置，如此用户设备可以避免功耗浪费并达到省电效果。
