本发明涉及电路域回落(CSFB，Circuit Switched Fallback)技术领域，尤其涉及一种CSFB的回落结果检测方法及装置、计算机存储介质。
背景技术
由于长期演进(LTE，Long Term Evolution)和2G/3G双模终端的无线通信是单一无线模式(Signal-radio mode)，因此，具有LTE和2G/3G接入能力的双模或者多模终端，在使用LTE接入时，无法传输2G/3G电路域业务信号。为了使终端(UE，User Equipment)在LTE接入或驻留下能够进行话音等电路域(CS，Circuit Switched)业务，并且能够对UE在LTE接入下正在进行的分组域(PS，Packet Switch)业务进行正确地处理，产生了CSFB技术。
在CSFB过程中，电话的发起者称为主叫(MO，Mobile Origination)，电话的接收者称为被叫(MT，Mobile Termination)，MO和MT各自对应有自己的CSFB信令流程。对于CSFB过程中的MT而言，由于各种异常情况的出现会概率性地导致CSFB过程失败，从而导致电话无法接通，如何有效检测异常场景下的CSFB的回落结果尤为必要。

具体实施方式
为了能够更加详尽地了解本发明实施例的特点与技术内容，下面结合附图对本发明实施例的实现进行详细阐述，所附附图仅供参考说明之用，并非用来限定本发明实施例。
正常情况下，具有CSFB功能的终端开机能够搜索LTE网络，完成LTE/2G网络联合注册，并能够进行语音主叫及被叫。
CSFB过程包括三个阶段：1)UE在LTE网络发起呼叫(对应于MO)，或者接收寻呼(对应于MT)；2)UE在LTE网络指引下回落并搜索合适的GSM小区/WCDMA小区进行接入；3)UE读取GSM小区/WCDMA小区系统广播消息并建立语音通话。
随着LTE基站规模不断地扩大，以及部分旧的GSM/TDSCDMA基站的退网和重耕，原有的网络部署在基站信令侧的配置并未实时更新，出现了网络下发给UE的配置信息和实际的部署情况不一致，从而导致CSFB这种跨系统(InterRAT)的语音通话出现各种异常情况，比如无法接通，重复连接失败等。
为解决此类因网络部署不兼容状况而带来的通话问题，各终端厂商采用了各种优化手段来提高通话体验，为验证CSFB优化方案的合理性，有 必要对异常场景下的CSFB过程进行检测，以便针对性地完善CSFB优化方案。
CSFB回落方案采用3GPP R8重定向回落方案，在CSFB部署过程中，因参数配置的问题会概率性地导致CSFB过程出现异常。为此，本发明实施例提供了一种由于网络侧指定的回落目标GSM小区被邻区TDSCDMA小区网络干扰而引起TDS RSCP上行汇报的场景下，CSFB回落结果的检测方法。
在本发明的各种实施例中，在基于指示终端采用预设的CSFB优化方案进行语音业务的指示信息执行CSFB过程中，检测所述终端在全球移动通信系统GSM网络下的语音通话状态；所述终端在GSM网络下的语音通话是基于指定的GSM小区被临小区时分同步码分多址TDSCDMA小区干扰而引起所述终端发起接收信号码功率RSCP上行报告后而触发的；至少基于检测的语音通话状态，判断所述CSFB是否回落成功；其中，所述指示信息携带在LTE基站向所述终端发送的附着接受消息中；所述附着接受消息是所述终端向LTE基站发送附着请求消息后所述LTE基站发送的；所述CSFB过程是所述终端接收到所述LTE基站发送的寻呼消息时触发执行的。
采用本发明实施例提供的方案，能够在由于网络侧指定的回落目标GSM小区被邻区TDSCDMA小区网络干扰而引起TDS RSCP上行汇报的场景下，检测CSFB过程中在GSM网络下的语音通话状态，从而最终确定出CSFB的回落结果，这样，在后续进行CSFB的过程中，可以进一步完善优化方案来提高CSFB过程成功的概率，以提升用户的呼叫体验。
图1为本发明实施例提供的CSFB的回落结果检测方法的流程示意图，如图1所示，所述CSFB的回落结果检测方法包括以下步骤：
步骤101：在基于指示终端采用预设的CSFB优化方案进行语音业务的 指示信息执行CSFB过程中，检测所述终端在全球移动通信系统GSM网络下的语音通话状态；
这里，所述终端在GSM网络下的语音通话是基于指定的GSM小区被临小区时分同步码分多址TDSCDMA小区干扰而引起所述终端发起接收信号码功率RSCP上行报告后而触发的。比如，终端在GSM网络下的语音通话是基于指定的GSM小区被临小区时分同步码分多址TDSCDMA小区干扰而引起所述终端发起针对TDSCDMA小区的接收信号码功率RSCP上行报告后而触发的。
其中，所述指示信息携带在LTE基站向所述终端发送的附着接受消息中；所述附着接受消息是所述终端向LTE基站发送附着请求消息后所述LTE基站发送的；所述CSFB过程是所述终端接收到所述LTE基站发送的寻呼消息时触发执行的。
实际应用时，可以通过实验室仿真的方式来构造一个应用于本发明实施例的网络环境，也就是说，本发明实施例所述终端所在的场景是通过仿真方式得到的，这样处理，一方面，工作人员不需要去现场检测，从而能够降低人员成本；另一方面，现场的场景有可能还包含了其他因素，从而影响检测结果，所以采用本发明实施例的仿真网络，能够稳定复现现场网络出现的CSFB异常场景，能够消除在本发明实施例所描述的场景下其他因素对检测结果的影响。
基于此，在一些实施例中，检测位于仿真网络环境下的所述终端在GSM网络下的语音通话状态。
步骤102：至少基于检测的语音通话状态，判断所述CSFB是否回落成功。
在一具体实施例中，当检测到所述终端在所述GSM网络的语音通话中断(也即未持续)时，确定所述CSFB回落失败。
在另一具体实施例中，在所述GSM网络下的语音通话结束后，检测所述终端是否在预设时长内返回LTE网络；当所述终端未在所述预设时长内返回LTE网络时，确定所述CSFB回落失败。这里，实际应用中，所述预设时长可以根据需要进行设置。
在一具体场景中，当检测到所述终端在所述GSM网络的语音通话未中断，即所述终端在所述GSM网络的语音通话建立后保持语音通话时，在所述GSM网络下的语音通话结束后，检测所述终端是否在预设时长内返回LTE网络；当所述终端未在所述预设时长内返回LTE网络时，确定所述CSFB回落失败。相应地，当所述终端在所述预设时长内返回LTE网络时，确定所述CSFB回落成功。也就是说，当检测到所述终端在所述GSM网络的语音通话未中断，即所述终端在所述GSM网络的语音通话建立后保持语音通话，且在所述GSM网络下的语音通话结束后，所述终端在所述预设时长内返回LTE网络时，确定所述CSFB回落成功。
在另一具体实施例中，所述方法还包括：检测到所述终端上报的测量报告指示所述终端支持UMTS陆地无线接入UTRA时，确定所述CSFB回落失败。比如，UE上报的测量报告MR中的终端能力(FGI)bit 22不等于0，此时，确定所述CSFB回落失败。
这里，实际应用时，可以通过相关的信令来检测所述终端在GSM网络的语音通话是否中断，同理，通过相关的信令来检测所述终端是否在预设时长内返回LTE网络，通过相关的信令来确定FGI bit 22是否为0。
这样，本发明实施例提供的方法，在基于指示终端采用预设的CSFB优化方案进行语音业务的指示信息执行CSFB过程中，检测所述终端在全球移动通信系统GSM网络下的语音通话状态；所述终端在GSM网络下的语音通话是基于指定的GSM小区被临小区时分同步码分多址TDSCDMA小区干扰而引起所述终端发起接收信号码功率RSCP上行报告后而触发的； 至少基于检测的语音通话状态，判断所述CSFB是否回落成功；其中，所述指示信息携带在LTE基站向所述终端发送的附着接受消息中；所述附着接受消息是所述终端向LTE基站发送附着请求消息后所述LTE基站发送的；所述CSFB过程是所述终端接收到所述LTE基站发送的寻呼消息时触发执行的。采用本发明实施例提供的方案，能够在由于网络侧指定的回落目标GSM小区被邻区TDSCDMA小区网络干扰而引起TDS RSCP上行汇报的场景下，检测CSFB过程中在GSM网络下的语音通话状态，从而最终确定出CSFB的回落结果，这样，在后续进行CSFB的过程中，可以进一步完善优化方案来提高CSFB过程成功的概率，以提升用户的呼叫体验。
另外，检测位于仿真网络环境下的所述终端在GSM网络下的语音通话状态，采用仿真的方式不需要工作人员去现场，且可以去除其他影响检测的因素，如此，能够大大降低人员成本，同时，能够消除在本发明实施例所描述的场景下其他因素对检测结果的影响。
下面结合一个应用实施例对本发明再作进一步详细的描述。
在本应用实施例中，通过仿真平台构造一个网络环境，包括频分双工(FDD)-LTE小区、TDSCDMA小区、GSM小区；其中，LTE SIB中配置TDSCDMA为邻区小区信息，配置GSM小区为邻区小区，在TDSCDMA SIB 18中配置LTE邻区小区信息。
本应用实施例的异常场景是：由于网络侧指定的回落目标GSM小区被邻区TDSCDMA小区网络干扰引起TDS RSCP上行汇报，导致UE未能回落到GSM通话，针对此异常场景，进行终端测量报告MR上报优化，从而验证终端侧通话优化方案的有效性和合理性。
本应用实施例CSFB的回落结果的检测方法，如图2所示，包括以下步骤：
步骤201：UE注册LTE小区上，进行附着流程；
具体地，UE为MT，UE开机后，首先执行联合演进分组系统(EPS，Evolved Packet System)/国际移动用户识别码(IMSI，International Mobile Subscriber Identification Number)附着流程。
其中，在这个过程中包括触发UE向LTE基站发送附着请求消息(Attach Request)，接收所述LTE基站发送的附着接受消息(Attach Accept)，其中，所述附着接受消息携带用于指示所述终端采用预设的CSFB优化方案进行语音业务的指示信息。图3为本发明实施例的仿真代码的示意图一，其中：IMS voice over PS(V)＝Not supported(0)，代表所述指示信息。
步骤202：网络侧配置RRC Reconfiguration，促使UE进行测量报告MR，对邻区TDSCDMA小区进行测量。
步骤203：网络侧触发MT CSFB流程，网络侧发送寻呼消息(Paging)给UE，开始CSFB流程；
这里，实际应用时，需要MO首先发起针对MT的呼叫，然后，MT才接收到网络侧下发的寻呼消息。
具体地，网络中的移动业务交换中心(MSC)收到初始地址请求(IAM)入局消息后，根据存在的SGs关联和移动管理实体(MME，Mobility Management Entity)信息，发送SGsAP-PAGING-REQUEST消息给MME，这里，SGsAP-PAGING-REQUEST消息携带如下信息：IMSI、临时移动用户标识(TMSI，Temporary Mobile Subscriber Identity)、业务标识(Service indicator)、主叫号码、位置区信息。
MME收到消息后发送寻呼(Paging)消息给基站，基站发起空口的Paging流程。UE建立连接并发送Extended Service Request消息给MME，MME发送SGsAP-SERVICE-REQUEST消息给MSC，MSC收到此消息，不再向MME重发寻呼请求消息。为避免呼叫接续过程中，主叫等待时间过长，MSC收到包含空闲态指示的SGs Service Request消息，先通知主叫呼 叫正在接续过程中。MME发送Initial UE Context Setup消息给基站，这里，Initial UE Context Setup消息携带CS Fallback Indicator，CS Fallback Indicator用于指示基站UE因CSFB业务需要回落到UMTS陆地无线接入网(UTRAN，UMTS Terrestrial Radio Access Network)/GSM/EDGE无线接入网(GERAN，GSM EDGE Radio Access Network)。
在附着流程中，UE收到LTE基站发送的LTE_RRCConnectionRelease信令，即重定向命令。重定向命令中携带有指定GSM小区的频点信息，也即目标GSM小区的频点信息。
如图4所示，基站下发R8重定向命令(rrcConnectionRelease_R8(0))给UE，该命令携带有目标GSM小区的频点信息，如此，便于UE基于R8重定向命令中携带的频点信息接入目标GSM小区。
步骤204：UE根据指定的频点信息(也即目标GSM小区的频点信息)接入GSM小区，此时，通过仿真平台模拟：UE根据指定的频点信息(也即目标GSM小区的频点信息)接入GSM小区进行语音通话的过程中，被邻区TDSCDMA小区网络干扰引起TDS RSCP上行汇报；
此时，检测UE在这种情况下，在目标GSM小区的语音通话状态；即检查UE在这种情况下，能否在目标GSM小区建立通话并保持CS域的通话不受影响，在CS通话结束之后，能迅速FastReturn成功返回LTE网络；也即是否能在预设时间内返回LTE网络。
步骤205：检查UE在这种情况下，CS域的语音通话状态是否不受到影响，即检测UE在这种情况下，是否能够保持语音通话，若是，则执行步骤206；否则，说明CSFB回落失败，也就是说，预设CSFB优化方案失败；
步骤206：检测通话结束后UE是否在预设时间长内返回LTE网络，若是，则说明CSFB回落成功，否则，说明CSFB回落失败。
步骤207：检测到UE上报的测量报告MR指示的FGI bit 22不等于0 时，确定CSFB回落失败。
实际应用中，步骤207与步骤205的执行顺序可以调换，本实施例对此不作限制。
这里，依据预设CSFB优化方案，当UE在TDSCDMA网络正常通话结束后，UE应当迅速返回LTE网络。
为实现本发明实施例的方法，本发明实施例还提供了一种CSFB的回落结果检测装置，如图5所示，所述装置包括：

  4. 根据权利要求1所述的方法，其中，所述方法还包括：
    检测到所述终端上报的测量报告指示所述终端支持UMTS陆地无线接入UTRA时，确定所述CSFB回落失败。
  5. 根据权利要求1所述的方法，其中，所述检测所述终端在GSM网络下的语音通话状态，包括：
    检测位于仿真网络环境下的所述终端在GSM网络下的语音通话状态。
  6. 一种电路域回落CSFB的回落结果检测装置，包括：
    检测单元，配置为在基于指示终端采用预设的CSFB优化方案进行语音业务的指示信息执行CSFB过程中，检测所述终端在全球移动通信系统GSM网络下的语音通话状态；所述终端在GSM网络下的语音通话是基于指定的GSM小区被临小区时分同步码分多址TDSCDMA小区干扰而引起所述终端发起接收信号码功率RSCP上行报告后而触发的；
    确定单元，配置为至少基于检测的语音通话状态，判断所述CSFB是否回落成功；
    其中，所述指示信息携带在LTE基站向所述终端发送的附着接受消息中；所述附着接受消息是所述终端向LTE基站发送附着请求消息后所述LTE基站发送的；所述CSFB过程是所述终端接收到所述LTE基站发送的寻呼消息时触发执行的。
  7. 根据权利要求6的检测装置，其中，所述确定单元，还配置为当检测到所述终端在所述GSM网络的语音通话中断时，确定所述CSFB回落失败。
  8. 根据权利要求6或7的检测装置，其中，所述检测单元，还配置为在所述GSM网络下的语音通话结束后，检测所述终端是否在预设时长内返回LTE网络；
    对应地，所述确定单元，还配置为当所述终端未在所述预设时长内返回LTE网络时，确定所述CSFB回落失败。
  9. 根据权利要求7的检测装置，其中，所述检测单元，还配置为检测 到所述终端上报的测量报告指示所述终端支持UMTS陆地无线接入UTRA；
    对应地，所述确定单元，还配置为当检测到所述终端上报的测量报告指示所述终端支持UMTS陆地无线接入UTRA后，确定所述CSFB回落失败。
  10. 根据权利要求6的检测装置，其中，所述检测单元，还配置为检测位于仿真网络环境下的所述终端在GSM网络下的语音通话状态。
  11. 一种电路域回落CSFB的回落结果检测装置，包括：处理器和用于存储能够在处理器上运行的计算机程序的存储器，其中，所述处理器用于运行所述计算机程序时，执行权利要求1至5所述方法的步骤。
  12. 一种计算机可读存储介质，其上存储有计算机程序，其中，该计算机程序被处理器执行时实现权利要求1至5所述方法的步骤。
