Description

一种CSFB的回落结果检测方法及装置、计算机存储介质 技术领域
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。
发明内容

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UE作为被叫接收呼叫(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网络侧指定的GSM小区弱信号接入失败，手机根据之前的GSM强信号小区LU记录来完成CSFB，验证手机侧通话优化方案的有效性和合理性。
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：当用户设备UE在长期演进LTE网络的小区进行注册时，生成针对所述UE的拒绝接入信息并发送至所述UE；其中，所述拒绝接入信息至少能够指示拒绝原因为所述UE未开通LTE服务；
步骤102：控制所述UE基于WCDMA网络发起呼叫，针对所述UE发起的呼叫进行检测得到检测结果，基于所述检测结果判断所述CSFB是否回落成功。
这里，本实施例所对应的执行主体可以为能够具备网络环境模拟功能的装置，也就是说，通过具备前述功能的装置模拟能够模拟至少一种网络的环境，比如，可以包括有GSM、LTE、5G或者NR等网络环境。
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。
前述步骤101中，当用户设备UE在长期演进LTE网络的小区进行 注册时，生成针对所述UE的拒绝接入信息并发送至所述UE，包括：
确定针对所述UE的拒绝接入的原因值为公共陆地移动网络禁止接入；
将所述原因值添加至所述拒绝接入信息并发送至所述UE。
其中，可以预先配置所述UE为未开通4G服务的UE；如此，该UE向LTE网络发起注册操作时，就能够触发对应的拒绝接入，并且在本实施例对应的装置侧，还可以预设策略，当检测到为开通4G服务的UE发起注册时，触发网络拒绝接入发送Attach Reject，cause值为PLMN(Public Land Mobile Network，公共陆地移动网络)NOT ALLOWED。
相应的，本实施例提供的装置执行步骤102，具体包括以下处理：
向所述UE配置预设频点；
控制所述UE基于所述预设频点接入所述WCDMA网络，并通过所述WCDMA网络向被叫发起呼叫。
也就是说，在UE侧还可以设置策略，当接收到前述原因值的拒绝接入信息时，可以根据网络侧预配置的频点接入WCDMA网络。
另外，通过所述WCDMA网络向被叫发起呼叫时，可以通过本实施例提供的装置模拟一个被叫端，从而能够更加准确的检测所述UE针对被叫号码发来的呼叫请求。
所述基于所述检测结果判断所述CSFB是否回落成功，包括：
当检测结果表征所述UE发起的呼叫失败，则判定所述CSFB回落失败；或者，当检测结果表征所述UE不能连接所述WCDMA网络的资源，则判定所述CSFB回落失败。
其中，两种判定方式效果并不相同，前一种，可以为UE能够接入到WCDMA资源，但是由于其他原因可能并无法完成呼叫，那么此时，可以严格的判定CSFB回落失败；后一种，只要未连接到WCDMA网络的 资源，就判定CSFB回落时报。
通过采用前述方案，就能够稳定复现出现网中小概率出现的CSFB异常情况，并验证了优化方案的可行性以及稳定性。
本发明实施例提供的方法，验证了由于UE未开通4G数据服务而导致被LTE网络拒绝接入，进而禁掉整个PLMN，当UE移动到此网络覆盖区时候，被叫电话无法接通的优化方案，验证手机侧通话的优化方案的可行性以及稳定性
通过采用前述方案，能够在UE无法接入LTE网络时，控制所述UE基于WCDMA网络发起呼叫，基于呼叫情况检测得到判断结果；如此，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。
仿真网络构造一个网络环境，包括FDD-长期演进(LTE，Long Term Evolution)/宽带码分多址(WCDMA，Wideband Code Division Multiple Access)/全球移动通信系统(GSM，Global System for Mobile Communication)小区，其中LTE系统信息块(SIB)中配置WCDMA 1为邻区小区信息，配置GSM小区为邻区小区。具体的，可以在WCDMA SIB18中配置LTE邻区小区信息。
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200：UE尝试注册到LTE小区上，模拟由于没有开通4G数据服 务，网络拒绝接入，发送Attach Reject，cause值为PLMN(Public Land Mobile Network，公共陆地移动网络)NOT ALLOWED，UE侧针对此cause进行优化，确保不会影响UE在同区域内3G/2G的服务；
本步骤中可以理解为，首先可以先模拟配置UE未开通4G数据服务，然后UE尝试注册时，就能够触发本实施例提供的装置检测到不具备接入LTE小区的UE发来的注册请求；
进而，本实施例提供的装置在发送拒绝接入的信息时，在该信息中添加原因值；其原因值可以根据实际情况进行设置，本实施例中将该原因值设置为PLMN NOT ALLOWED。
进一步地，如此能够触发UE侧基于该原因值进行优化处理。
步骤201：UE根据指定的频点信息找到WCDMA，模拟网络作为被叫MT call，模拟手机作为主叫发起MO call，检测UE是否能够接通；
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)。
步骤202：若检测到UE不能连接WCDMA资源进行语音通话，则判定优化方案失败。
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3所示，所述装置包括：
控制信息下发单元31，用于当用户设备UE在长期演进LTE网络的小区进行注册时，生成针对所述UE的拒绝接入信息并发送至所述UE；其中，所述拒绝接入信息至少能够指示拒绝原因为所述UE未开通LTE服务；

前述控制信息下发单元31，确定针对所述UE的拒绝接入的原因值为公共陆地移动网络禁止接入；
将所述原因值添加至所述拒绝接入信息并发送至所述UE。
其中，可以预先配置所述UE为未开通4G服务的UE；如此，该UE向LTE网络发起注册操作时，就能够触发对应的拒绝接入，并且在本实施例对应的装置侧，还可以预设策略，当检测到为开通4G服务的UE发起注册时，触发网络拒绝接入发送Attach Reject，cause值为PLMN(Public Land Mobile Network，公共陆地移动网络)NOT ALLOWED。
相应的，检测单元32，向所述UE配置预设频点；
