Description

用于小区切换的方法、装置及用户设备 技术领域
本公开涉及通信技术领域，尤其涉及一种用于小区切换的方法、装置及用户设备。
背景技术
随着无线通信技术的飞速发展以及各种智能终端的普及，移动数据流量将呈现爆炸式增长，超密集网络(Ultra-Dense Network，简称为UDN)技术成为第五代移动通信技术(5th Generation，简称为5G)网络提高数据流量的关键技术之一。在超密集网络中，微基站密集的部署使得小区数量剧增，并且由于小区边界更多、更不规则，导致更为复杂和频繁的切换，难以保证移动性性能。为了缓解超密集网络场景下小区切换问题所导致的难以保证移动性性能的问题，5G无线接入网络中提出了一种条件切换的方式来缓解上述问题。
相关技术中，在5G项目的研究讨论中，条件切换(Conditional Handover)技术是指基站在向用户设备(User Equipment，简称为UE)发送切换命令后，UE不会立即执行小区切换，而是仅在条件满足后才执行小区切换。相关技术中，UE接收到切换命令之后仍立即启动切换定时器T304，并且在定时器超时时，在无线链路失败报告(Radio Link Failure-Report，简称为VarRLF-Report)中记录连接失败类型为切换失败，在条件切换时，UE所记录的VarRLF-Report的内容是不准确的，导致基站不能准确定位切换失败问题，进而不能调整UE的小区切换触发，提高了UE的移动性性能。

具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本发明相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本发明的一些方面相一致的装置和方法的例子。
图1A是根据一示例性实施例示出的一种用于小区切换的方法的流程图，图1B是根据一示例性实施例示出的一种用于发送和接收系统消息的方法的场景图；该用于小区切换的方法可以应用在UE上，如图1A所示，该用于小区切换的方法包括以下步骤110-130：
在步骤110中，接收到基站发送的预设切换命令时，确定每一个目标小区对应的切换判决参数。
在一实施例中，预设切换命令用于表示条件切换命令，UE在接收到条件切换命令后不即时执行小区切换，而是在目标小区满足切换条件时才执行小区切换操作。
在一实施例中，每一个目标小区对应的切换判决参数可以包括但不限于以下任一一种或者两种以上参数的组合：参考信号接收功率(Reference Signal Receiving Power，简称为RSRP)、接收的信号强度指 示(Received Signal Strength Indicator，简称为RSSI)、参考信号接收质量(Reference Signal Receiving Quality，简称为RSRQ)。
在一实施例中，每一个目标小区对应的切换判决参数可以不相同，例如，目标小区A对应的切换判决参数为RSSI大于-75dBm，目标小区B对应的切换判决参数为RSSI大于-85dBm。
在一实施例中，可以通过解析预设切换指令得到每一个目标小区对应的切换判决参数。
在步骤120中，当基于每一个目标小区对应的切换判决参数确定出满足切换条件的目标小区时，启动预设定时器并且执行从当前服务小区切换到满足切换条件的目标小区的小区切换操作。
在一实施例中，UE在接收到条件切换命令后，可实时对每一个目标小区进行测量，得到每一个目标小区的测量结果，当有目标小区的测量结果与对应的切换判决参数匹配时，即可确定出该目标小区满足切换条件。例如，如果目标小区A的切换判决参数为RSSI大于-75dBm，而UE测量得到的目标小区A的RSSI为-70dBm，则可确定目标小区A满足切换条件。
在一实施例中，预设定时器可以为T304定时器，即在进行小区切换时使用定时器T304的时长；在一实施例中，预设定时器也可以为其它的预设的用于小区切换的定时器。
在一实施例中，预设切换命令中还可以携带有目标小区的无线链路配置信息，UE可以基于预设切换命令中的无线链路配置信息执行小区切换操作。
在步骤130中，当小区切换操作执行失败时，在无线链路失败报告中记录第一切换信息。
在一实施例中，小区切换操作执行失败可以理解为在UE还没有成功切换到目标小区时，预设定时器已经超时；或者在切换过程中发生无线链路失败的情况，等等。
在一实施例中，第一切换信息包括但不限于以下任意一种或者两种以上的组合：连接失败类型为条件切换失败，接收到预设切换命令的时刻与小区切换操作执行失败时的时刻之间的时间间隔，启动预设定时器的时刻与小区切换操作执行失败时的时刻之间的时间间隔，执行所述小区切换操作的目标小区的小区标识信息。
在一实施例中，当基站向UE索取无线链路失败报告时，UE可以将携带有无线链路失败报告的报告消息发送至基站。
在一示例性场景中，如图1B所示，以移动网络为LTE网络并且基站为演进型基站(eNB)为例进行示例性说明，在图1B所示的场景中，包括eNB10、UE20，其中，UE20接收到eNB10发送的预设切换命令时，可先确定出满足切换条件的目标小区，再启动预设定时器并且执行小区切换操作，当小区切换失败时，在无线链路失败报告中记录第一切换信息，第一切换信息包括但不限于连接失败类型为条件切换失败、接收到预设切换命令的时刻与小区切换操作执行失败时的时刻之间的时间间隔、启动预设定时器的时刻与小区切换操作执行失败时的时刻之间的时间间隔、执行所述小区切换操作的目标小区的小区标识信息，因此基站在索取无线链路失败报告后可基于第一切换信息定位切换失败问题，进而保证UE能够触发切换过程，尽量避免发生无线链路失败，提高UE的移动性性能。
本实施例通过上述步骤110-步骤130，可以使UE在接收到执行条件切换的命令时在开始执行小区切换操作时再启动预设定时器，以保证UE能够触发切换过程，避免发生无线链路失败，提高UE的移动性性能。
在一实施例中，用于小区切换的方法进一步还可以包括：
当基于每一个目标小区对应的切换判决参数确定出满足切换条件的目标小区之前发生无线链路失败时，在无线链路失败报告中记录第二切换信息。
在一实施例中，第二切换信息包括：接收到预设切换命令的时刻与发生无线链路失败的时刻之间的时间间隔。
在一实施例中，第一切换信息包括以下任意一种或者两种以上的组合：连接失败类型为条件切换失败，接收到预设切换命令的时刻与小区切换操作执行失败时的时刻之间的时间间隔，启动预设定时器的时刻与小区切换操作执行失败时的时刻之间的时间间隔，执行所述小区切换操作的目标小区的小区标识信息。
在一实施例中，用于小区切换的方法进一步还可以包括：
对每一个目标小区的信号进行实时测量，得到每一个目标小区对应的测量结果；
基于每一个目标小区对应的测量结果和每一个目标小区对应的切换判决参数，确定每一个目标小区是否满足切换条件。
在一实施例中，用于小区切换的方法进一步还可以包括：
当小区切换操作执行成功时，停止预设定时器。
在一实施例中，用于小区切换的方法进一步还可以包括：
接收基站发送的获取无线链路失败报告的请求消息；
向基站发送携带所述无线链路失败报告的报告消息。
具体如何进行小区切换的，请参考后续实施例。
至此，本公开实施例提供的上述方法，可以确定出满足切换条件的目标小区时启动预设定时器并且执行小区切换操作，以保证UE能够触发切换过程，避免发生无线链路失败，提高UE的移动性性能；并且在发生无线链路失败时能够准确记录条件切换中的切换信息，进而绑定基站进行切换失败问题的定位，以便修改相应的参数，尽量避免UE发生无线链路失败。
下面以具体实施例来说明本公开实施例提供的技术方案。
图2是根据一示例性实施例示出的另一种用于小区切换的方法的流程图；本实施例利用本公开实施例提供的上述方法，以UE进行条件切换为例进行示例性说明，如图2所示，包括如下步骤：
在步骤210中，接收到基站发送的预设切换命令时，确定每一个目 标小区对应的切换判决参数，预设切换命令用于表示条件切换命令。
在步骤220中，对每一个目标小区的信号进行实时测量，得到每一个目标小区对应的测量结果。
在一实施例中，测量结果可以包括RSRP的值、和/或RSSI的值、和/或RSRQ的值。
在步骤230中，基于每一个目标小区对应的测量结果和每一个目标小区对应的切换判决参数，确定每一个目标小区是否满足切换条件，当基于每一个目标小区对应的切换判决参数确定出满足切换条件的目标小区时，执行步骤240，当基于每一个目标小区对应的切换判决参数确定出满足切换条件的目标小区之前发生无线链路失败时，执行步骤270。
在一实施例中，可以将每一个目标小区的测量结果与切换判决参数进行对比，如果有目标小区的测量结果与切换判决参数匹配，则说明目标小区满足切换条件，否则说明目标小区不满足切换条件。
在一实施例中，当有两个以上的目标小区满足切换条件时，可以选择目标小区信号质量更好的目标小区作为要切换至的目标小区。
在步骤240中，当基于每一个目标小区对应的切换判决参数确定出满足切换条件的目标小区时，启动预设定时器并且执行从当前服务小区切换到满足切换条件的目标小区的小区切换操作，执行步骤250和步骤260。
在一实施例中，步骤240的描述可参见图1A所示实施例的步骤120的描述，这里不再详述。
在步骤250中，当小区切换操作执行失败时，在无线链路失败报告中记录第一切换信息，第一切换信息用于上报至基站。
在一实施例中，小区切换操作执行失败可以理解为在UE还没有成功切换到目标小区时，预设定时器已经超时；或者在切换过程中发生无线链路失败的情况，等等。
在一实施例中，第一切换信息包括但不限于以下任意一种或者两种以上的组合：连接失败类型为条件切换失败，接收到预设切换命令的时刻 与小区切换操作执行失败时的时刻之间的时间间隔，启动预设定时器的时刻与小区切换操作执行失败时的时刻之间的时间间隔，执行所述小区切换操作的目标小区的小区标识信息。
在步骤260中，当小区切换操作执行成功时，停止预设定时器。
在步骤270中，当基于每一个目标小区对应的切换判决参数确定出满足切换条件的目标小区之前发生无线链路失败时，在无线链路失败报告中记录第二切换信息，第二切换信息用于上报至基站。
在一实施例中，第二切换信息包括但不限于：接收到预设切换命令的时刻与发生无线链路失败的时刻之间的时间间隔。
本实施例中，UE可以确定出满足切换条件的目标小区时启动预设定时器并且执行小区切换操作，以保证UE能够触发切换过程，避免发生无线链路失败，提高UE的移动性性能；并且在发生无线链路失败时能够准确记录条件切换中的切换信息，进而绑定基站进行切换失败问题的定位，以便修改相应的参数，尽量避免UE发生无线链路失败。
图3是根据一示例性实施例示出的又一种用于小区切换的方法的流程图；本实施例利用本公开实施例提供的上述方法，以如何上报无线链路失败报告为例进行示例性说明，如图3所示，包括如下步骤：
在步骤310中，接收基站发送的获取无线链路失败报告的请求消息。
在一实施例中，通常UE在发生切换失败或者无线链路失败等问题时，可以向基站发送指示消息，基站可根据需要向UE发送索取无线链路失败报告的请求消息。
在步骤320中，向基站发送携带无线链路失败报告的报告消息。
在一实施例中，当UE在还没有确定出满足切换条件的目标小区之前，就发生无线链路失败时，无线链路失败报告中可以记录接收到预设切换命令的时刻与发生无线链路失败的时刻之间的时间间隔。
在一实施例中，UE启动预设定时器执行小区切换操作时发生切换失败时，无线链路失败报告中可以记录连接失败类型为条件切换失败，接收 到预设切换命令的时刻与小区切换操作执行失败时的时刻之间的时间间隔，启动预设定时器的时刻与小区切换操作执行失败时的时刻之间的时间间隔。
本实施例中，由于UE在执行条件切换的过程中在无线链路失败报告中记录的信息与在执行直接切换的过程中在无线链路失败报告中记录的信息不相同，因此可以有效帮助基站区分出不同的切换方式，以及减小基站定位切换失败问题的难度，进而减小发生无线链路失败的可能性。
