现有技术中，主要通过源网络基站和目标网络基站分别统计重定向成功次数，将统计的重定向成功次数上报到NMS设备上；或者源网络基站和目标网络基站分别跟踪、保存和上报重定向相关信令到NMS设备，由NMS进行计算或者信令匹配获取重定向成功率和重定向时延的统计结果，根据统计结果进行网络优化。
但是，由于当前大多数网络基站受限于基站处理性能、网络传输带宽、信令存储空间等多种因素约束，基站只能统计局部区域重定向的KPI，使得NMS无法对当前整个网络的覆盖性能进行统计，不利于网络优化。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，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，都属于本发明保护的范围。

实施例一
图1示出了本发明实施例提供的反应业务连续性结果和质量的方法的流程图，如图1所示，所述方法可以包括：
101、UE记录所述UE从源网络切换/重定向到目标网络时的结果和过程信息。
其中，所述源网络可以为所述UE当前接入的网络，所述目标网络可以为所述UE准备切换/重定向到的网络，切换/重定向可以指所述UE断开与源网络的业务接入，重新在指定的目标网络中发起业务接入的过程；所述业务可以为现有网络中任一类型的业务，如语音业务、其他服务质量(QoS)要求较高的业务等。
所述切换/重定向的结果和过程信息可以为切换/重定向结果和切换/重定向时延信息；其中，切换/重定向时延信息是网络侧统计采用切换/重定向方式进行业务类型在目标网络转移的指标之一，切换/重定向时延越长，用户对网络服务感受(QoE)越差；所述切换/重定向时延信息可以包括：切换/重定向时延、切换/重定向的起止点；所述切换/重定向时延的起止点既可以由源网络节点配置给UE，也可以由UE在上报测量值的时候同时上报起止点；优选的，所述切换/重定向的起点可以为目标网络接收到UE发起的业务请求的时刻，所述切换/重定向的终止点可以为UE在目标网络发送第一个业务包的结束时刻；切换/重定向结果可以为切换/重定向成功和切换/重定向失败两种结果，切换/重定向成功表示：UE与目标网络建立连接，可以在目标网络内发起业务，如：UE从源网络中释放，并接入到目标网络一定的时间，则认为切换/重定向成功；切换/重定向失败表示：UE未能与目标网络建立连接，不能在目标网络内发起业务；
可选的，UE可以将下述(1)(2)(3)(4)(5)任一种情况记录为切换/重定向失败：
(1)在UE未收到源网络节点发送的切换/重定向命令时，所述UE已发生无线链路失败(Radio Link Failure，RLF)。
(2)UE收到源网络节点发送的切换/重定向命令后，从源网络中释放，向所述目标网络发起随机接入信道(Random Access Channel，RACH)时失败。
(3)UE收到源网络节点发送的切换/重定向命令后，从源网络中释放，向所述目标网络发起RACH时成功，但在向目标网络 发送无线资源控制(Radio Resource Control，RRC)连接建立请求时，被目标网络的网络节点以预设原因拒绝。
其中，所述预设原因由所述目标目标网络的网络节点根据需要预先设置，可以包括：负载控制，所述UE与所述目标网络的网络节点之间未签约等。
(4)UE收到源网络节点发送的切换/重定向命令后，从源网络中释放，向所述目标网络发起RACH接入时成功，但在向目标网络的网络节点发送业务请求时，被目标网络的网络节点拒绝。
(5)UE收到源网络节点发送的切换/重定向命令后，从源网络中释放，向所述目标网络发起RACH接入时成功，但在预设时间内，所述UE在目标网络中发生掉话。
其中，所述切换/重定向命令用于命令所述UE进行切换/重定向；所述预设时间可以根据需要进行设置，本发明实施例对此不进行限制。
可选的，本发明实施例中，当记录的切换/重定向结果为切换/重定向失败时，UE还需要记录与当前切换/重定向失败相对应的失败原因，例如，上述第(2)中情况下的失败原因为：目标网络RACH接入失败；上述第(3)中情况下的失败原因为：目标网络RRC连接请求拒绝；上述第(4)中情况下的失败原因为：目标网络业务请求拒绝；上述第(5)中情况下的失败原因为：在目标网络内掉话。
102、UE向网络节点上报记录的所述切换/重定向结果和过程信息。
其中，所述网络节点可以为网络中控制整个网络的设备，如基站、演进基站(Evolved EodeB，eNodeB)、无线网络控制器(Radio Network Controller，RNC)、核心网节点、运营操作维护节点等等；
本发明实施例中，所述网络节点可以是所述源网络的网络节点，还可以是所述目标网络的网络节点，也可以是第三网络的网络节点，其中，所述第三网络为所述UE在切换/重定向失败后选择 的不同于所述源网络和所述目标网络的网络。
可选的，UE可以通过下述(1)(2)(3)中的任一种方式上报记录的所述切换/重定向结果和过程信息：
(1)当所述网络节点是源网络的网络节点时，所述UE向网络节点上报记录的所述切换/重定向的结果和过程信息具体包括：
所述UE存储所述切换/重定向的结果和过程信息，待所述UE重新接入到所述源网络后，在所述源网络内向所述源网络的网络节点上报记录的所述切换/重定向的结果和过程信息。
例如，UE可以将测量的切换/重定向结果和过程信息存储48个小时，在这48小时内，等到UE回到源网络时在所述源网络上报保存的切换/重定向结果和过程信息。
(2)当所述网络节点是目标网络的网络节点时，所述UE向网络节点上报记录的所述切换/重定向的结果和过程信息具体包括：
所述UE向所述目标网络的网络节点上报所述切换/重定向的结果和过程信息，由所述目标网络的网络节点通过网络间接口转发到所述源网络的网络节点，由所述源网络的网络节点根据所述切换/重定向的结果和过程信息进行相应处理；或者，
所述UE直接在所述目标网络中向目标网络的网络节点上报所述切换/重定向的结果和过程信息，由所述目标网络的网络节点根据所述切换/重定向的结果和过程信息进行相应处理。
(3)当所述网络节点是第三网络的网络节点时，所述UE向网络节点上报记录的所述切换/重定向的结果和过程信息具体包括：
所述UE向所述第三网络的网络节点上报所述切换/重定向的结果和过程信息，由所述第三网络的网络节点通过网络间接口转发到所述源网络的网络节点；或者，
所述UE直接向所述第三网络的网络节点上报所述切换/重定向的结果和过程信息，由所述第三网络的网络节点根据所述切换/ 重定向的结果和过程信息进行相应处理。
其中，所述相应处理可以指：网络节点根据所述切换/重定向的结果和过程信息进行网络优化等处理。
可选的，本发明实施例中，UE还需要根据源网络节点下发的命令或者自身配置触发执行上述方法，具体的，在步骤301之前，所述方法还可以包括：
所述UE接收所述源网络节点发送的第一无线资源控制(Radio Resource Control，RRC)信令；其中，所述第一RRC信令在所述源网络节点确定所述UE进行切换/重定向时包含在切换/重定向命令中发送或者在所述源网络节点确定UE进行切换/重定向之前发送；所述第一RRC信令用于命令所述UE从源网络切换/重定向到目标网络时记录并上报切换/重定向的结果和过程信息、以及指示上报切换/重定向的结果和过程信息的方式；所述切换/重定向命令用于命令所述UE进行切换/重定向；或者，
所述UE默认在所述UE发生切换/重定向时记录切换/重定向的结果和过程信息，并向所述网络节点上报所述切换/重定向的结果和过程信息。
可选的，为了更有利用源网络节点对整个网络覆盖性能的评估，本发明实施例中，所述UE还需要记录测量时间、测量时所述UE的位置信息等其他一些附加信息，并向源网络节点上报这些附加信息。
如此，由UE记录切换/重定向过程中的切换/重定向结果和过程信息并上报给网络侧节点，使得网络节点根据UE上报的信息收集到传统路测无法进行的全区域的测量信息，因此，可以更加客观的评估网络覆盖性能，有利于进一步优化网络。
进一步的，本发明实施例中，除了收集切换/重定向结果和切换/重定向时延信息等无线接入层的相关测量信息之外，为了使网络侧节点优化的网络更的更加贴近用户体验，给用户带来更高的满意度，本发明实施例中，UE还需要测量能够直接反应用户体验的 相关信息，如：切换/重定向过程中所述UE分别在所述源网络和所述目标网络中的业务质量参数信息时，并向网络节点上报所述业务质量信息，以使得网络节点根据收集到的UE上报的业务质量信息，计算出UE在目标网络中的业务质量结果(如语音业务的语音质量值(voice quality indication，VQI))，用于后续的网络优化，具体实现如下：
所述UE接收所述源网络节点发送的第一无线资源控制(Radio Resource Control，RRC)信令；其中，所述第一RRC信令在所述源网络节点确定所述UE进行切换/重定向时包含在切换/重定向命令中发送或者在所述源网络节点确定UE进行切换/重定向之前发送；所述第一RRC信令用于命令所述UE从源网络切换/重定向到目标网络时记录并上报所述业务质量参数信息、以及指示上报所述业务质量参数信息的方式；所述切换/重定向命令用于命令所述UE进行切换/重定向；或者，所述UE默认在所述UE发生切换/重定向时记录所述业务质量参数信息，并向网络节点上报所述所述业务质量参数信息；
UE在所述UE处于预设条件时记录所述业务质量参数信息，并向网络节点上报所述业务质量参数信息，由网络节点根据所述上报的业务质量参数信息计算出所述UE在所述源网络和所述目标网络中的业务质量结果信息。
其中，所述业务质量参数信息为反映业务的服务质量的参数信息，可以包括一个或多个周期性的测量记录值或者事件触发的记录值：丢包率、时延、时延抖动、编码速率、连续误帧率等多种参数信息，例如：
上行接入层包时延、上行应用层包时延、下行接入层包时延、下行应用层包时延、上行接入层包抖动、上行应用层包抖动、下行接入层包抖动、下行应用层包抖动、上行接入层包丢包率、上行应用层包丢包率、下行接入层包丢包率、下行应用层包丢包率、上行接入层包连续误帧率、上行应用层包连续误帧率、下行接入层包连 续误帧率、下行应用层包连续误帧率、语音包编码方式、语音包编码速率；接入层可以是：分组数据汇聚协议(Packet Data Convergence Protocol，PDCP)层PDCP层或者无线链路控制(Radio Link Control，RLC)层或者介质访问控制(Media Access Control，MAC)层；应用层可以是：实时传输协议(Real-time Transport Protocol，RTP)层或者Codec层或者用户数据包协议(User Datagram Protocol，UDP)层等。
所述预设条件可以包括下述一种或多种条件：
切换发生(如UE收到切换命令)；UE测量的参考信号接收功率(Reference Signal Receiving Power，RSRP)/参考信号接收质量(Reference Signal Receiving Quality，RSRQ)低于预设门限；UE测量的下行信号与干扰噪声比(Signal to Interference Noise Ratio，SINR)低于预设门限值；UE感受到的包时延或者抖动、丢包等QOS参数低于预设门限值。
进一步的，本发明实施例中，UE还可以在一定的触发条件下(如接收到源网络节点下发的命令或者自身默认)根据记录的切换/重定向过程中所述UE分别在所述源网络和所述目标网络中的业务质量参数信息计算切换/重定向过程中所述UE分别在所述源网络和所述目标网络中的业务质量结果信息，并向网络节点上报所述业务质量结果信息，以使得网络节点直接根据业务质量结果进行后续的网络优化，具体如下：
UE在所述UE处于预设条件时记录所述UE分别在所述源网络和所述目标网络中的业务质量参数信息，并根据所述业务质量参数信息计算切换/重定向过程中所述UE分别在所述源网络和所述目标网络中的业务质量结果信息，向网络节点上报所述业务质量结果信息。
其中，所述业务质量结果信息可以为直接反映业务质量的最终结果值，包括下述一个或多个周期性的测量记录值或者事件触发的记录值：语音质量平均意见(Mean Opinion Score，MOS)、客观的 语音质量分数(Voice Quality Indication，VQI)值。
可选的，UE可以采用现有方法根据业务质量参数信息计算业务质量结果，在此不再赘述；例如，可以将业务质量参数信息(如误块率(Block Error Ratio，BLER)、误码率(Bit Error Rate，BER)、连续删帧率、切换数进行线性拟合获得VQI值。
由上可知，本发明实施例提供一种反应业务连续性结果和质量的方法，由UE记录切换/重定向过程中的结果和过程信息并上报给网络侧节点，使得网络节点根据UE上报的信息收集到传统路测无法进行的全区域的测量信息，可以更加客观的评估网络覆盖性能，有利于进一步优化网络，避免了现有网络侧只能统计局部区域的重定向指标而导致的不利于网络优化的问题。
