一种SRVCC测量上报方法、SRVCC测量上报装置以及终端
本申请要求于2016年04月18日提交中国专利局，申请号为201610239220.9、发明名称为“一种SRVCC测量上报方法、SRVCC测量上报装置以及终端”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及通信技术领域，尤其涉及一种SRVCC测量上报方法、SRVCC测量上报装置以及终端。
背景技术
IP多媒体子系统 （IP Multimedia Subsystem，IMS）是一种全新的多媒体业务形式，能够满足现在的客户终端更新颖、更多样化多媒体业务的需求，长期演进（Long Term Evolution，LTE）网络作为一种IP网络，其标准的语音方案就是采用IMS承载LTE网络下的语音业务，即LTE网络语音业务（Voice over LTE，VoLTE），VoLTE构架于运营商的网络之上，使得运营商能够为VoLTE提供更高级别的控制和管理。
VoLTE作为LTE的终极语音解决方案，其语音可以完全使用分组交换PS域来实现，接入网通过PS分组域承载，会话控制以及业务数据传输基于IP实现，可避免对现有的2G或3G CS蜂窝网络的依赖性。然而，在LTE网络布网的初期，不会达到全网覆盖范围，主要是对热点区域进行覆盖，逐步由点及面，当部署的LTE网络提供语音业务时，在LTE网络中发起语音业务的用户一旦离开LTE网网络覆盖范围，即用户从LTE网络漫游到诸如只有GSM（Global System for Mobile Communication）/UMTS（Universal Mobile Telecommunicaitons System）网络的区域时，为了保证语音业务不掉话，原有的LTE网络语音接入就需要切换到GSM/UMTS网络中，单待无线语音呼叫连续性（Single Radio Voice Call Continuity，SRVCC）就保证了切换的过程中用户语音业务不中断，解决了基于LTE网络的语音业务向GSM/UMTS网络的语音业务的无缝切换，提高运营商服务质量。
在现有技术中，SRVCC切换过程完全由网络侧来主导，网络侧会在无线资源控制（Radio Resource Control，RRC）重配时，携带B1 或B2事件的信息，让终端UE进行异系统测量上报，但在现有网络中，有时由于网络侧故障或者RRC重配不及时，将会导致网络未通知到UE并让其进行异系统小区测量以及上报，最终导致UE在LTE上脱网掉话，从而影响用户体验。B1事件表示异系统邻区质量高于一定门限，B2事件表示服务小区质量低于一定门限并且异系统邻区质量高于一定门限。
综上所述，如何提供一种SRVCC测量上报方法，以解决由于网络侧故障或者RRC重配不及时未通知UE进行异系统小区测量而导致无法完成SRVCC切换的问题，是本专业技术人员亟待解决的问题。
发明内容
本发明实施例提供了一种SRVCC测量上报方法、SRVCC测量上报装置以及终端，通过终端主动进行异系统小区测量，可以有效解决由于网络侧故障或者RRC重配不及时未通知终端进行异系统小区测量而导致无法完成SRVCC切换的问题，从而保证了语音业务的连续性，提高了运营商的服务质量，进而避免了客退客诉。
有鉴于此，本发明第一方面提供了一种SRVCC测量上报方法，可包括：
在终端的VoLTE通信过程中，终端实时检测长期演进LTE网络的信号强度是否小于当前预设门限；
若是，则终端启动异系统小区测量，并将测量信息上报至网络侧，以使得网络侧根据测量信息判断是否进行单待无线语音呼叫连续性SRVCC切换。
结合本发明实施例的第一方面，在本发明实施例的第一方面的第一种实施方式中，当前预设门限为当前LTE信号门限和预设容错经验值的和。
结合本发明实施例的第一方面的第一种实施方式，在本发明实施例的第一方面的第二种实施方式中，方法还包括：
当网络侧发生无线资源控制RRC重配时，终端从网络侧下发的重配信息中获取第一LTE信号门限；
终端利用第一LTE信号门限更新当前LTE信号门限。
结合本发明实施例的第一方面的第一种实施方式或第二种实施方式，在本发明实施例的第一方面的第三种实施方式中，在终端将测量信息上报至网络侧之后，该方法还包括：
若网络侧根据测量信息判断进行SRVCC切换，则终端获取网络侧进行SRVCC切换时测量信息中的第二LTE信号门限；
终端利用第二LTE信号门限更新当前LTE信号门限。
本发明第二方面提供一种SRVCC测量上报装置，可包括：
检测模块，设置为在终端的VoLTE通信过程中，实时检测长期演进LTE网络的信号强度是否小于当前预设门限；
启动模块，设置为当检测模块检测信号强度小于当前预设门限时，则启动异系统小区测量；
上报模块，设置为将测量信息上报至网络侧，以使得网络侧根据测量信息判断是否进行单待无线语音呼叫连续性SRVCC切换。
结合本发明实施例的第二方面，在本发明实施例的第二方面的第一种实施方式中，当前预设门限为当前LTE信号门限和预设容错经验值的和。
结合本发明实施例的第二方面的第一种实施方式，在本发明实施例的第二方面的第二种实施方式中，SRVCC测量上报装置还包括：
第一获取模块，设置为当网络侧发生无线资源控制RRC重配时，从网络侧下发的重配信息中获取第一LTE信号门限；

第二更新模块，设置为利用第二LTE信号门限更新当前LTE信号门限。
本发明第三方面提供一种终端，包括上述实施例的第二方面的SRVCC测量上报装置。
从以上技术方案可以看出，本发明实施例具有以下优点：
本实施例中，当终端进行VoLTE通信时，终端可以在该通信过程中实时检测长期演进LTE网络的信号强度是否小于当前预设门限，若是，则终端可以启动异系统小区测量，并将测量信息上报至网络侧，以使得网络侧能够根据测量信息判断是否进行单待无线语音呼叫连续性SRVCC切换。从上述描述过程可以得知，不同于现有技术，终端不需要网络侧下发B1或B2事件，即可根据LTE网络的信号强度自动启动异系统小区测量，从而有效避免了由于网络侧故障或者RRC重配不及时未通知终端进行异系统小区测量而导致无法完成SRVCC切换的问题。

具体实施方式
本发明实施例提供了一种SRVCC测量上报方法、SRVCC测量上报装置以及终端，用于解决由于网络侧故障或者RRC重配不及时未通知终端进行异系统小区测量而导致无法完成SRVCC切换的问题，进而保证语音业务的连续性，提高运营商的服务质量，避免客退客诉。
为了使本技术领域的人员更好地理解本发明方案，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的实施例，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做出创造性劳动前提下所获得的所有其他实施例，都应当属于本发明保护的范围。
本发明的说明书和权利要求书及上述附图中的术语“第一”、“第二”、“第三”、“第四”等（如果存在）是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的实施例能够以除了在这里图示或描述的内容以外的顺序实施。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
为便于理解，下面对本发明实施例中的具体流程进行描述，请参阅图1，本发明实施例中SRVCC测量上报方法一个实施例包括：
101、在终端的VoLTE通信过程中，终端实时检测长期演进LTE网络的信号强度是否小于当前预设门限，若否，则执行步骤102，若是，则执行步骤103；
本实施例中，终端可以是向用户提供VoLTE语音业务的设备，该设备可以是移动终端，如移动电话，也可以是具有移动终端的计算机，如便携式的移动装置。VoLTE作为基于IMS的语音业务，是一种IP数据传输技术，无需2G/3G网络，全部业务承载于LTE网络，即4G网络上，然而LTE网络部署初期其覆盖率较低，为了避免用户原本在LTE网络覆盖区域进行VoLTE通信，而漫游到只有GSM/UMTS网络的区域时出现的掉话问题，SRVCC可将承载源网络的基于IP的VoLTE语音业务平滑切换到目标CS域，用以保持语音业务的连续性。
在实际应用中，SRVCC切换由网络侧主导，通过给终端下发B1或B2事件使得终端能够进行异系统小区测量，但是由于网络侧故障或RRC重配不及时，并不能使终端及时进行异系统小区测量以完成SRVCC切换，导致终端在LTE网络的信号强度越来越弱的情况下最终脱网掉话。为了避免此种情况，在终端的VoLTE通信过程中，终端可以实时检测长期演进LTE网络的信号强度是否小于当前预设门限，即通过LTE网络的信号强度来判断终端是否远离LTE网络的覆盖区域。
本实施例中，当前预设门限可以为当前LTE信号门限和预设容错经验值的和，此处限定之后，在后面即不再重复限定。
可以理解的是，终端可以在出厂前对当前预设门限进行提前设定，上述说明的当前LTE信号门限可以为终端判断是否远离LTE网络覆盖区域的阈值，预设容错经验值是为了避免终端测量以及上报测量信息的时间差而导致终端已远离当前LTE信号门限或以上覆盖的范围时，但终端仍未进行异系统小区测量以完成SRVCC切换而造成的脱网掉话问题，该设容错经验值就是个经验值，如取10分贝毫伏，若假设当前LTE信号门限为20分贝毫伏，那么若当前预设门限即为当前LTE信号门限，则只有当LTE网络的信号强度小于20分贝毫伏时，终端才开始进行异系统小区测量，可能导致终端还未来得及进行SRVCC切换就已脱网掉话，而若当前信号门限为当前LTE信号门限和预设容错经验值的和，则当LTE网络的信号强度小于30分贝毫伏时，终端就可以启动异系统小区测量，则可以有效避免终端在LTE网络的信号强度不断衰减的情况下未及时完成SRVCC切换导致的脱网掉话问题。需要说明的是，在实际应用中，本实施例中的预设容错经验值也可以取其他经验值，且由于不同地区的网络配置的SRVCC切换门限可以不同，从而当前LTE信号门限以及预设容错经验值可以随地区有所不同，当前LTE信号门限也可以动态调整，具体此处不做限定。
本实施例中的SRVCC切换门限可以由网络侧决定，此处限定之后，在后面即不再重复限定。
102、执行其它流程；
若在终端的VoLTE通信过程中，终端实时检测LTE网络的信号强度不小于当前预设门限，那么说明终端还未远离LTE网络的覆盖区域，则终端可以不进行其它的操作，并可以在此LTE网络的信号强度下继续进行VoLTE通信，而不会造成脱网掉话的问题。
103、终端启动异系统小区测量，并将测量信息上报至网络侧，以使得网络侧根据测量信息判断是否进行单待无线语音呼叫连续性SRVCC切换。
若在终端的VoLTE通信过程中，终端实时检测LTE网络的信号强度小于当前预设门限，则意味着LTE网络的信号强度越来越弱，有可能造成脱网掉话的问题，那么终端可以启动异系统小区测量，并将测量信息上报至网络侧，以使得可以网络侧根据测量信息判断是否进行单待无线语音呼叫连续性SRVCC切换。
本实施例中，异系统小区可以是与终端当前的服务小区属于不同网络制式的邻区。
进一步的，在实际应用中，如图2所示的信令交互图，该基于LTE网络的信号强度进行的SRVCC切换可以通过以下具体流程实现：
1、在VoLTE通信过程中实时检测LTE网络的信号强度，若小于预设门限，则启动异系统小区测量
2、当终端UE进行异系统小区测量后，可以将测量信息上报至E-UTRAN 中的eNodeB，该测量信息可以包括LTE网络的信号强度和异系统小区网络的信号强度，E-UTRAN为LTE网络系统的接入网部分，包括eNodeB等；
3、eNodeB可以根据上报的测量信息，判断LTE网络的信号强度和异系统小区网络的信号强度是否满足SRVCC切换条件；
4、若满足，则eNodeB可以发起SRVCC切换到GSM/UMTS网络，即终端向移动性管理实体MME发起切换请求消息，并可以标识该切换为SRVCC；
5、接收到SRVCC切换请求消息后，MME可以通过和移动交互中心服务器MSC Server 之间的Sv接口发起SRVCC切换流程，将语音承载切换到MSC Server；
6、MSC Server完成语音承载切换流程的同时，可以通过目标UTRAN/EGRAN发起到3GPP IMS域的会话切换流程，并指示IMS域完成会话层的切换；
7、MSC Server完成CS 域的承载资源准备后，通过Sv接口通知MME；
8、MME 通过E-UTRAN 指示终端开始进行SRVCC切换切换；
9、UE执行SRVCC切换过程，切换完成后将通话承载在CS域上，从而保证了语音业务的连续性。
可以理解的是，从上述说明的内容可知，本实施例中的SRVCC切换仍由网络侧确定是否执行，在实际应用中，网络侧也可以下发B1或B2事件使得终端进行异系统小区测量，但只要终端检测LTE网络的信号强度小于预设门限时，便可主动进行异系统小区测量。
本实施例中，针对终端的VoLTE通信过程，终端可以实时检测LTE网络的信号强度，当该信号强度小于当前预设门限时，终端可以主动进行异系统小区测量，并主动上报测量信息，由网络侧来决定是否进行切换，而不是待网络侧下发B1或B2事件时才开始进行异系统小区测量，从而有效解决了由于网络侧故障或者RRC重配不及时未通知终端进行异系统小区测量而导致无法完成SRVCC切换的问题，以保证语音业务的连续性，提高运营商服务质量，避免客退客诉。
需要说明的是，本实施例中终端可以自主完成当前预设门限的动态更新，可以根据网络侧下发的第一LTE信号门限进行更新，也可以根据在网络侧进行SRVCC切换时的第二LTE信号门限进行更新，下面分别进行说明：
请参阅图3，本发明实施例中SRVCC测量上报方法另一实施例包括：
本实施例中的步骤301至步骤303与图1所示实施例中的步骤101至步骤103相同，此处不再赘述。
304、当网络侧发生无线资源控制RRC重配时，终端从网络侧下发的信息中获取第一LTE信号门限；
本实施例中，当网络侧的通信链路发生变化时，网络侧将进行无线资源控制RRC重配，并可以向终端下发RRC重配消息。当终端接收到该重配消息后，可以从该重配消息中获取第一LTE信号门限，该第一LTE信号门限可以为当前地区的网络配置的SRVCC切换门限。
305、终端利用第一LTE信号门限更新当前LTE信号门限。
当终端从网络侧下发的信息中获取到第一LTE信号门限后，可以利用第一LTE信号门限更新当前LTE信号门限，即将当前信号门限的值替换为第一LTE信号门限的值。
例如，假设当前LTE信号门限为30分贝毫伏，若终端在网络侧下发的重配消息中获取第一LTE信号门限为25分贝毫伏，那么终端可以将当前LTE信号门限更新为25分贝毫伏，在后续的VoLTE通信过程中，终端将以25分贝毫伏的当前LTE信号门限为基础，实时检测LTE网络的信号强度。需要说明的是，当前LTE信号门限的初始值以及第一LTE信号门限都可以是基于实际情况的其它数值，本实施例只是举例说明。
可以理解的是，本实施例中的步骤304至步骤305可以在步骤301至步骤303之前、之间或之后进行，只要使得终端可以利用重配消息中获取第一LTE信号门限更新当前LTE信号门限即可，具体此处不做限定。
基于图1所示实施例说明的有益效果，本实施例中，由于不同地区的网络配置的SRVCC切换门限不同，从而当网络侧发生RRC重配时，可以下发包含有当前地区的SRVCC切换门限的重配消息给终端，即第一LTE信号门限，终端可以利用该第一LTE信号门限更新当前预设门限，完成终端的当前预设门限的动态更新，有效结合网络配置的实际情况，提高终端的实时检测效率。
请参阅图4，本发明实施例中SRVCC测量上报方法另一实施例包括：
本实施例中的步骤401至步骤403与图1所示实施例中的步骤101至步骤103相同，此处不再赘述。
404、若网络侧根据测量信息判断进行SRVCC切换，则终端获取网络侧进行SRVCC切换时测量信息中的第二LTE信号门限；
本实施例中，若网络侧根据上报的测量信息判断可以进行SRVCC切换，则网络侧可以通知终端进行SRVCC切换，那么终端可以获取网络侧在进行SRVCC切换时测量信息中的第二LTE信号门限，该第二LTE信号门限即为网络侧判断能够进行SRVCC切换时由终端实时检测到的LTE网络的信号强度值，该第二LTE信号门限可以携带在测量信息中由终端上报至网络侧。
405、终端利用第二LTE信号门限更新当前LTE信号门限。
当终端获取网络侧进行SRVCC切换时测量信息中的第二LTE信号门限后，可以利用第二LTE信号门限更新当前LTE信号门限，即将当前信号门限的值替换为第二LTE信号门限的值。
例如，假设当前LTE信号门限为25分贝毫伏，若终端在VoLTE过程中检测到LTE网络的信号强度为20分贝毫伏，且网络侧判断在该信号强度下可以进行SRVCC切换，则终端可以在上报测量信息后获取网络侧进行SRVCC切换时测量信息中的第二LTE信号门限，即为20分贝毫伏，且可以将当前LTE信号门限更新为20分贝毫伏，那么在后续的VoLTE通信过程中，终端将以20分贝毫伏的当前LTE信号门限为基础，实时检测LTE网络的信号强度。需要说明的是，当前LTE信号门限的初始值以及第二LTE信号门限都可以是基于实际情况的其它数值，本实施例只是举例说明。
基于图1所示实施例说明的有益效果，本实施例中，当终端上报测量信息后，若网络侧根据上报的测量信息判断可以进行SRVCC切换，则终端可以获取网络侧判断能够进行SRVCC切换时由终端自身实时检测到的LTE网络的信号强度值，即第二LTE信号门限，且终端可以利用该第二LTE信号门限更新当前预设门限，使得终端可以根据网络侧的SRVCC切换情况动态更新当前预设门限，以达到较佳的当前预设门限，更有利于终端及时主动进行异系统小区测量。
需要说明的是，图3所示实施例以及图4所示实施例也可以进行结合，即终端可以根据第一LTE信号门限以及第二LTE信号门限进行当前预设门限的动态更新，具体此处不做限定。

本实施例中，检测模块501检测的当前预设门限为当前LTE信号门限和预设容错经验值的和。
本实施例中，针对终端的VoLTE通信过程，检测模块501可以实时检测LTE网络的信号强度，当该信号强度小于当前预设门限时，启动模块502可以主动进行异系统小区测量，上报模块503可以主动上报测量信息，由网络侧来决定是否进行切换，而不是待网络侧下发B1或B2事件时才开始进行异系统小区测量，从而有效解决了由于网络侧故障或者RRC重配不及时未通知终端进行异系统小区测量而导致无法完成SRVCC切换的问题，以保证语音业务的连续性，提高运营商服务质量，避免客退客诉。
