Description

一种通信方法及移动终端 技术领域
本发明涉及通信领域，尤其涉及一种VoLTE(Voice over LTE(Long Term Evolution，长期演进)，LTE语音)技术。
背景技术
4G(the 4th Generation mobile communication technology，第四代移动通信技术)不仅仅提供高速率的数据业务，同时还提供高质量的音视频通话，其中高质量的音视频通话通过VoLTE(Voice over LTE(Long Term Evolution，长期演进)，LTE语音)技术来实现。在实际使用中，有可能存在移动终端在4G网络与2G(the 2nd Generation mobile communication technology，第二代移动通信技术)/3G(the 3th Generation mobile communication technology，第三代移动通信技术)的CS(Circuit Switching，电路交换)网络之间移动的情况，为了保证语音呼叫的连续性，3GPP(3rd Generation Partnership Project，第三代合作伙伴计划)提出了一种VoLTE语音业务连续性方案，即SRVCC(Single Radio Voice Call Continuity，单射频无线语音呼叫连续性)。保证单射频UE在IMS控制的VoIP语音和CS域语音之间的平滑切换。SRVCC通常有三种情况，对应通话建立的三个状态，分别是bSRVCC(Before alerting Single Radio Voice Call Continuity，振铃前的VoLTE语音业务连续性方案)，aSRVCC(Alerting Single Radio Voice Call Continuity，振铃中的VoLTE语音业务连续性方案)以及eSRVCC(Enhanced Single Radio Voice Call Continuity，增强型的VoLTE语音通话中业务连续性方案)。bSRVCC由于是发生在振铃之前，用户终端一直处于资源协商，查询阶段，涉及网元较多，容易发生网元间的碰撞导致呼叫失败，从而导致用户体验较差。现有 技术中，在语音呼叫建立前，如果LTE网络信号质量比较差，则直接将语音呼叫承载在CS域，可以降低出现bSRVCC的几率。然而，上述方案只能降低主叫bSRVCC的几率，未解决被叫bSRVCC的几率。被叫侧若bSRVCC切换失败，则会出现鬼振铃，或一直响铃，或接听没有声音，影响用户体验。

附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作一简单地介绍，显而易见地，下面描述中的附图是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动性的前提下，还可以根据这些附图获得其他的附图。
图1为VoLTE发起呼叫的流程图；
图2为本发明实施例VoLTE移动终端的通信流程图；
图3为本发明实施例的一种移动终端；
图4为本发明实施例的另一种移动终端。
具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，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描述，显然，所描述的实施例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。
Volte移动终端在通话过程中，由于网络覆盖原因，当Volte移动终端有通话的时候，LTE中基站eNodeB下发网络质量测量控制，移动终端收到eNodeB下发的网络质量测量控制后，其GSM(Global System for Mobile Communication，全球移动通信系统)物理层进行网络质量测量，得到的测量结果由移动终端的无线资源控制模块上报给网络侧。当2G/3G信强度高于某门限(例如，该门限由eNODEB配置为10～15db)时，无线资源控制模块 上报B1测量报告，当2G/3G信强度高于某门限(例如，该门限由eNODEB配置为10～15db)、4G信号强度低于某门限(例如，该门限由eNODEB配置为24～28db)时，无线资源控制模块上报B2测量报告。网络侧根据B1测量报告或B2测量报告决定是否进行异系统切换，即网络侧根据B1测量报告或B2测量报告决定是否将Volte移动终端的通话由4G网络承载切换到2G/3G网络承载。所述“有通话”不仅仅包括移动终端已与对端接通的情况，还包括移动终端发起呼叫还未与对端接通以及有来电还未接通的情况，即响铃前、响铃中以及通话建立都属于“有通话”的状态。
如图1所示，为Volte移动终端发起呼叫的流程。从图中可以看出，当Volte移动终端发起呼叫时，在响铃前，移动终端处于资源协商、查询阶段，涉及网元以及流程、信令比较多，如果此时网络侧根据B1测量报告或B2测量报告决定移动终端的通话由Volte网络承载切换到2G/3G网络承载时，则较容易发生网元间的碰撞，如，从4G网络往2G/3G网络切换的流程嵌套，导致终端通话异常，例如出现鬼振铃，或一直响铃，或接听没有声音，影响用户体验。
为解决上述问题，本发明实施例提供一种通信方法，如图2所示，当移动终端发起呼叫或有来电的时候，移动终端监控接入控制模块状态，一个实施例中，该监控由无线资源控制模块，例如，RRC(Radio Resource Control，无线资源控制)来完成，在一个实施例中，接入控制模块为IP多媒体子系统接入控制模块；如果监控到接入控制模块状态是INIT初始化状态，即振铃前，则启动呼叫流程保护，所述呼叫流程保护可以是暂停网络质量的测量，在一个实施例中，所述网络质量为网络的信号强度。所述呼叫流程保护可以是暂停触发网络质量报告上报，在一个实施例中，暂停触发网络质量报告上报包括暂停触发B1测量报告上报或B2测量报告上报。在具体的实现中，根据不同运营商的设定确定暂停触发何种测量报告上报。启动呼叫流程保护，则呼叫或来电直接在本系统中进行业务承载，保 证本系统内协议流程的完整性，防止发生振铃前的异系统切换。
当接入控制模块的状态发生改变，例如，接入控制模块的状态变为START状态，即启动状态，此时终端处于振铃中，则结束呼叫流程保护，进行网络质量的测量以及向网络侧上报网络质量报告。在其中一个实施例中，所述网络质量报告为B1测量报告或B2测量报告，在移动终端有SRVCC需求时，进行SRVCC；
当接入控制模块的状态是END状态，即已完成接入流程，此时通话双方的通信通路已建立，则不启动呼叫流程保护，如启动了呼叫流程保护，则关闭呼叫流程保护，进行网络质量的测量以及向网络侧上报B1测量报告或B2测量报告，在移动终端有SRVCC需求时，进行SRVCC。
本发明的上述实施例，在移动终端端发起呼叫或有来电的时候，通过监控IMSA的状态，在容易异系统切换失败的振铃前状态，暂停网络质量测量，或暂停触发网络质量测量报告上报，防止发生bSRVCC，使得移动终端在振铃前不进行异系统切换，从而避免切换失败，进一步避免因切换失败引起的终端通话异常，提升用户体验。
如图3所示，本发明实施例还提供一种移动终端300，所述移动终端300包括检测单元301、获取单元302以及处理单元303。当移动终端发起呼叫或有来电的时候，检测模块301检测到移动终端有通话业务，获取单元302监控移动终端接入控制模块状态，一个实施例中，该获取单元302为无线资源控制模块。在一个实施例中，接入控制模块为IP多媒体子系统接入控制模块；如果获取单元302监控到接入控制模块状态是INIT初始化状态，即振铃前，则处理单元303启动呼叫流程保护，所述呼叫流程保护可以是暂停网络质量的测量，在一个实施例中，所述网络质量为网络的信号强度。所述呼叫流程保护可以是暂停触发网络质量报告上报，在一个实施例中，暂停触发网络质量报告上报包括暂停触发B1测量报告上报或B2测量报告上报。在具体的实现中，根据不同运营商的设定确定暂停触发何 种测量报告上报。启动呼叫流程保护，则呼叫或来电直接在本系统中进行业务承载，保证本系统内协议流程的完整性，防止发生振铃前的异系统切换。
当获取单元302监控到接入控制模块的状态发生改变，例如，接入控制模块的状态变为START状态，即启动状态，此时终端处于振铃中，则处理单元303结束呼叫流程保护，进行网络质量的测量以及向网络侧上报网络质量报告。在其中一个实施例中，所述网络质量报告为B1测量报告或B2测量报告，在移动终端有SRVCC需求时，进行SRVCC；
当获取单元302监控到接入控制模块的状态是END状态，即已完成接入流程，此时通话双方的通信通路已建立，则处理单元303不启动呼叫流程保护，如启动了呼叫流程保护，则处理单元303关闭呼叫流程保护，进行网络质量的测量以及向网络侧上报B1测量报告或B2测量报告，在移动终端有SRVCC需求时，进行SRVCC。
本发明的上述实施例，在移动终端端发起呼叫或有来电的时候，通过监控IMSA的状态，在容易异系统切换失败的振铃前状态，暂停网络质量测量，或暂停触发网络质量测量报告上报，防止发生bSRVCC，使得移动终端在振铃前不进行异系统切换，从而避免切换失败，进一步避免因切换失败引起的终端通话异常，提升用户体验。
如图4所示，为本发明实施例提供的一种移动终端400，所述移动终端400包括基带芯片401、无线资源模块402以及处理器403。本实施例中所述移动终端的基带芯片401可以是单独的基带芯片也可以是包括射频芯片的基带芯片。当移动终端发起呼叫或有来电的时候，基带芯片401检测到移动终端有通话业务，无线资源模块402监控移动终端接入控制模块状态，一个实施例中，该无线资源模块402为无线资源控制模块。在一个实施例中，接入控制模块为IP多媒体子系统接入控制模块；如果无线资源模块402监控到接入控制模块状态是INIT初始化状态，即振铃前，则处理器 403启动呼叫流程保护，所述呼叫流程保护可以是暂停网络质量的测量，在一个实施例中，所述网络质量为网络的信号强度。所述呼叫流程保护可以是暂停触发网络质量报告上报，在一个实施例中，暂停触发网络质量报告上报包括暂停触发B1测量报告上报或B2测量报告上报。在具体的实现中，根据不同运营商的设定确定暂停触发何种测量报告上报。启动呼叫流程保护，则呼叫或来电直接在本系统中进行业务承载，保证本系统内协议流程的完整性，防止发生振铃前的异系统切换。
当无线资源模块402监控到接入控制模块的状态发生改变，例如，接入控制模块的状态变为START状态，即启动状态，此时终端处于振铃中，则处理器403结束呼叫流程保护，进行网络质量的测量以及向网络侧上报网络质量报告。在其中一个实施例中，所述网络质量报告为B1测量报告或B2测量报告，在移动终端有SRVCC需求时，进行SRVCC；
当无线资源模块402监控到接入控制模块的状态是END状态，即已完成接入流程，此时通话双方的通信通路已建立，则处理单元303不启动呼叫流程保护，如启动了呼叫流程保护，则处理器403关闭呼叫流程保护，进行网络质量的测量以及向网络侧上报B1测量报告或B2测量报告，在移动终端有SRVCC需求时，进行SRVCC。
本发明的上述实施例，在移动终端端发起呼叫或有来电的时候，通过监控IMSA的状态，在容易异系统切换失败的振铃前状态，暂停网络质量测量，或暂停触发网络质量测量报告上报，防止发生bSRVCC，使得移动终端在振铃前不进行异系统切换，从而避免切换失败，进一步避免因切换失败引起的终端通话异常，提升用户体验。
