背景技术
在移动通信系统中，通过引入网络自优化的机制，减少网络规划和操作维护的人工参与，降低网络的建设和运营成本，即，由网络根据统计量自动优化参数。移动健壮性优化是SON(Self-Organizing Network，网络自组织)中的一个重要的方面。
在移动网络中，切换参数设置不合适会严重影响系统性能，以及用户的服务体验，最严重的情况是导致用户掉话。因此移动性参数自优化是SON所要解决的最重要的问题之一，它要能够减少切换失败的发生，减少不当切换导致的用户掉话，以及减少不必要的切换，避免这些切换对系统资源的无效使用。

具体实施方式
为了使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请作进一步地详细描述，显然，所描述的实施例仅仅是本申请一部份实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其它实施例，都属于本申请保护的范围。
参见图1，图1是本申请实施例涉及的一种通信系统的架构示意图；该通信系统包括网络侧设备101以及终端设备102。其中终端设备102与网络侧设备101通过某种空口技术相互通信。所述空口技术可包括：2G(如全球移动通信系统GSM)、3G(如通用移动通信系统(Universal Mobile Telecommunications System，UMTS)、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)、时分同步码分多址(Time Division-Synchronous  Code Division Multiple Access，TD-SCDMA))、4G(如频分双工长期演进技术Frequency Division Duplexing Long Term Evolution，FDD LTE、时分双工长期演进技术Long Term Evolution，TDD LTE)以及新空口New RAT系统，例如5G系统等。
本申请实施例中所描述的终端设备102将以一般意义上的UE来介绍。此外，终端设备102也可以为移动台、接入终端、用户单元、用户站、移动站、远方站、远程终端、移动设备、用户终端、用户设备、无线通信设备、用户代理或用户装置等。用户设备可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol，SIP)电话、无线本地环路(Wireless Local Loop，WLL)站、个人数字处理(Personal Digital Assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备以及5G网络中的移动台或者未来演进的公共陆地移动网(Public Land Mobile Network，PLMN)网络中的用户设备等。此外，在本申请实施例中，终端设备102还可以包括中继(Relay)等其他能够和网络侧设备101(例如，基站)进行数据通信的设备。
在本申请实施例中，下文中的基站均指网络侧设备101，下文中不做赘述。
随着网络架构向扁平化和分布式发展，自组织网络(SON)将成为未来无线网络的关键技术之一。目前部署的4G无线网络中有许多网元和相关参数由人工配置，这些设备和参数的规划、配置、维护、管理都关系到网络的可靠高效运行，由此产生的运营费用(OPEX)是相当巨大的。运营商一方面要降低运营支出，降低管理复杂度，使网络运营更加简单高效，另一方面要提供较好的终端用户体验。
SON的主要目标是减少人工对网络规划、配置和优化的参与，提高网络管理的自动化程度，一方面可以降低网络运营商的网络运行开销，另一方面可以提高网络性能。SON自优化功能需要监测一些网络和系统性能参数并将其作为输入，如网络性能指标的统计、故障告警、通知等，在对输入数据进行分析后，优化算法做出决策，最后自动触发相关网络节点的调整操作，如 有必要，也可由人工触发。
在移动网络中，切换参数设置不合适会严重影响系统性能，以及用户的服务体验，最严重的情况是导致用户掉话。因此移动性参数自优化是SON所要解决的最重要的问题之一，它要能够减少切换失败的发生，减少不当切换导致的用户掉话，以及减少不必要的切换，避免这些切换对系统资源的无效使用。
基于上述内容，本申请实施例提供一种移动健壮性优化系统，包括终端设备、终端设备在切换前连接的源基站，终端设备在切换时的目标基站以及终端设备发生连接失败后接入的第一基站，终端设备在接入所述第一基站之前接入的第二基站。
可选的，在本申请实施例中，第二基站可以与源基站为同一基站，第二基站也可以与目标基站为同一基站。
基于上述系统，本申请实施例提供一种移动健壮性优化方法，应用于终端设备，如图2所示，包括：
步骤201，终端设备接收第一基站发送的上报连接失败信息指示；所述第一基站为所述终端设备发生连接失败后接入的基站；

示例性的，终端设备在切换过程中接入了两个基站，分别为eNB1和eNB2，eNB1和EPC(第四代通信系统的核心网)连接，eNB2既连接EPC又连接5GC(第五代通信系统的核心网)，则当eNB2连接5GC时，从eNB1到eNB2的切换就是一个核心网切换到另一个核心网的切换。

可选的，在本申请实施例中，终端设备获取到的连接失败信息中，除了包括网络切换类型外，还包括连接失败类型、第二基站的基站信息以及终端设备在切换过程中的源基站的基站信息和目标基站的基站信息。
在本申请实施例中，连接失败类型包括切换过程中发生切换失败、切换成功后发生无线链路失败RLF(Radio Link Failure)中的任一种。也就是说，一种连接失败的场景是终端设备在源基站进行切换时，未连接到目标基站，即切换过程中发生切换失败；另一种连接失败的场景是终端设备在源基站切换时，连接到了目标基站，然后发生的连接失败，即切换成功后发生无线链路失败RLF。

在步骤302中，第一基站获取终端设备反馈的连接失败信息，连接失败信息中包括了网络切换类型，网络切换类型用于指示所述切换过程是否为不同核心网之间的切换。
在步骤303中，第一基站将获取到连接失败信息发送给第二基站，即第一基站要向第二基站发送确定失败原因指示信息，且指示信息中包括连接失败信息，以使第二基站能够根据连接失败信息确定连接失败原因，第二基站为终端设备在接入所述第一基站之前接入的服务基站。示例性的，若连接失败类型为切换过程中发生切换失败，则第二基站就是重建基站；若连接失败类型为无线链路失败RLF，则第二基站为通过RRC指令接入的基站。
可选的，在本申请实施例中，第一基站发送给第二基站的确定失败原因指示信息中，还包括连接失败类型、所述第二基站的基站信息、所述终端设备在切换过程中的源基站的基站信息和目标基站的基站信息。

可选的，在本申请实施例中，第二基站根据确定失败原因指示信息确定是否为同一核心网之间的切换，然后再确定是否为同一无线接入技术之间的切换，从而确定连接失败原因。
可选的，在本申请实施例中，连接失败通常是由于切换参数设置不合理导致的，包括以下几种情况：
a)终端设备没有及时切换到一个无线信号较好的基站，而原来的服务基站信号不断恶化直至掉话，这种情况称为“过迟切换”，意味着切换应当更早 进行，但由于参数设置得不合适使得切换被延迟了。
b)另一种情况，终端设备从源基站切换到目标基站，但是目标基站信号并不稳定，结果切换后很快就发生无线链路失败，随后终端设备选择了一个新的基站重建无线连接，这种情况称为“切换到错误基站”，意味着切换的目标选择不合适，重建连接的那个基站才是一个合适的目标，而原来选择的目标并不合适。
c)还有一种情况，终端设备从源基站切换到目标基站，但很快发生了无线链路失败，随后终端设备选择了在源基站重建无线连接，这种情况称为“过早切换”。
可选的，在本申请实施例中，考虑了是否为同一核心网之间切换的场景，即网络切换类型这个因素，连接失败原因包括下列原因中的任一种：

对于inter-rat定义了过早切换，过迟切换，判断标准如下：

为了更好的解释本申请实施例提供的一种移动健壮性优化方法，在此举例说明。
如图5所示，终端设备UE连接了两个基站，分别为eNB1以及eNB2，eNB1和EPC(4G核心网)连接，eNB2既连接EPC又连接5GC。对于一个只支持4G的UE来说，从eNB1到eNB2的切换只能是4G系统内切换；但是，对于一个支持5G的UE来说，从eNB1到eNB2的切换可以是4G系统内切换也可能是4G系统到5G系统的切换。
某一时刻，eNB1根据UE的测量上报决定将UE切换到eNB2，而且切换后保持该UE在4G系统内，UE在切换过程中发生了失败，然后在eNB1进行重建。重建失败后，UE在eNB3发起RRC连接建立，在发起RRC连接建立后，eNB3获取UE连接失败相关的信息。
具体步骤为：
步骤501，eNB1将UE切换到eNB2，切换过程中发生切换失败；
步骤502，UE在eNB3发起RRC连接建立，并成功建立连接；
步骤503，eNB3请求UE上报连接失败相关的信息；
步骤504，UE上报连接失败相关的信息至eNB3；
UE上报给eNB3这是一次切换失败，UE最后的服务基站是eNB1，切换的目标基站是eNB2，为了提供给eNB3这次切换失败的切换类型，UE在向eNB3上报信息的时候需要通知eNB3这是一次系统内切换。
步骤505，eNB3发送无线链路失败指示至eNB1；
eNB3根据收到的UE的失败相关的信息，发送无线链路失败指示RLF indication消息给eNB1，该消息中携带UE的连接失败相关信息。
步骤506，eNB1根据收到的信息判断这是一次系统内的eNB1到eNB2的过迟切换，记录该信息，后续根据统计的信息进行参数的优化。
为了更好的解释本申请实施例提供的一种移动健壮性优化方法，在此举例说明。
如图6所示，在本申请实施例中，eNB1既连接EPC又连接5GC。对于一个支持4G也支持5G的UE来说，从gNB1到eNB1的切换可以是5G系统内切换也可能是5G系统到4G系统的切换。
某一时刻，gNB1根据UE的测量上报决定将UE切换到eNB1，而且切换后保持该UE在5G系统内，UE在切换过程中发生了失败，然后在gNB2发起RRC连接建立，在发起RRC连接建立后，gNB2获取UE连接失败相关的信息。
具体步骤为：
步骤601，gNB1将UE成功的切换到eNB1；
步骤602，UE在gNB2发起RRC连接建立；
步骤603，gNB2请求UE上报连接失败相关的信息；
步骤604，UE上报失败信息，包括连接失败之前的切换是一次系统内切换；
UE上报给gNB2这是一次无线链路失败，UE最后的服务基站是eNB1，失败之前，UE发生了一次切换，从gNB1切换到eNB1。同时，UE在向gNB2上报信息的时候需要通知gNB2失败之前的切换是一次系统内切换。
步骤605，gNB2发送无线链路失败指示RLF indication消息给eNB1；
gNB2根据收到的UE的失败相关的信息，发送RLF indication消息给eNB1，该消息中携带UE的连接失败相关信息。
步骤606，eNB1根据收到的信息判断这是一次系统内的gNB1到eNB1的过早切换；
步骤607，eNB1给gNB1发送切换报告HO REPORT消息，在该消息中，携带这次失败是系统内的过早切换引起的；
步骤608，gNB1记录该信息，后续根据统计的信息进行参数的优化。
