Description

网络切换处理方法及装置 技术领域
本发明涉及通信领域，具体而言，涉及一种网络切换处理方法及装置。
背景技术
3GPP规范定义LTE和移动网络演进目标是采用IMS MMTel(IP多媒体子系统，多媒体电话)向用户提供多媒体语音业务。LTE/EPC可看作是MMTel的无线宽带接入网络。
网络要保证LTE终端在向GSM/WCDMA网络漫游时语音业务的连续性。基于网络的切换能力以及终端的切换能力，LTE终端向GSM/WCDMA网络切换时如果目标网络可以提供足够的带宽并支持MMTel切换，则可以基于MMTel进行PS间的切换保障语音业务的连续性；另外3GPP规范定义了LTE到GSM/WCDMA网络间的PS到CS的切换技术，即双模单待无线语音呼叫连续性(Single Radio Voice Call Continuity，简称为SRVCC)，即在切换时利用目标网络的CS域保持语音业务的连续性，借助运营商已有的软交换系统向终端用户提供连续的语音业务。
基于SRVCC网络技术，LTE核心网络的MME与现网软交换MSC Server之间要建立基于IP的信令接口Sv接口。该接口在用户从LTE无线网络向GSM/WCDMA漫游时由用户终端触发PS到CS的语音业务切换。
终端用户在原LTE网络下的承载可能除了有基于GBR(Guaranteed Bit Rate)的语音承载外，还可能同时有非GBR的数据承载，在网络和终端具备条件的情形下也要进行相应的处理。
LTE向GSM网络漫游，且不进行DTM(Dual Transfer Mode)的SRVCC简要切换流程如下。
S1，手机向演进基站(e-Node B)发送测量报告；
S2，演进基站(e-Node B)判定进行向GSM进行SRVCC切换；
S3，e-Node B发送切换请求；
S4，MME进行语音承载与数据承载的分离，对QCI＝1的GBR语音承载进行到CS域的切换；
S5，MME向MSC Server发送PS到CS的切换请求(内含IMSI和STN-SR号码)；
S6，MSC Server与目标MSC Server和BSC协商完成GSM无线系统切换电路的建立；
S7，MSC Server向IMS MMTel发起语音会话转移传送信息(含STN-SR号码)；
S8，IMS MMTel进行语音会话的更新和用户面的承载更新；
S9，MSC Server向MME发送PS到CS的切换响应消息；
S10，MME向EnodeB发送切换命令消息；
S11，EnodeB向用户终端发送切换命令消息；
S12，用户终端切换到GSM，用户终端通过BSC发送PS业务挂起，SGSN与MME互通PS挂起消息；
S13，BSC向目标MSC Server发送切换完成消息；
S14，MSC Server向MME发送切换完成消息；
S15，根据规范流程MME与SGw/PGw互通进行相应的LTE承载处理和挂起。
在目标网络GSM或WCDMA支持和终端手机支持的情况下，SRVCC的切换同时可能伴随PS到PS的切换。PS到CS的切换要涉及到网络的S3/S4接口或Gn接口；同时进行PS到PS的切换可使得在LTE网络如Web浏览的数据业务在目标网络中保持连续。
目前的SRVCC技术中，针对语音呼叫的切换已经有了相关的技术方案。同时针对语音呼叫振铃阶段到UTRAN和GSM的SRVCC切换也都有了具体的技术方案。但是针对终端支持在语音呼叫过程中SRVCC切换到GSM网络的能力的验证和测试方法目前还是一个空白。
因此，在相关技术中存在不能实现对终端支持SRVCC切换的能力进行验证的问题。

具体实施方式
下文中将参考附图并结合实施例来详细说明本发明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。
在本实施例中提供了一种网络切换处理方法，图1是根据本发明实施例的网络切换处理方法的流程图，如图1所示，该流程包括如下步骤：
步骤S102，发送由源网络多模单频无线语音呼叫连续性SRVCC切换到目标网络的切换消息；
步骤S104，判断是否检测到终端在目标网络发送的切换测试成功响应消息；
步骤S106，在判断结果为是的情况下，确定终端由源网络SRVCC切换到目标网络切换成功。
通过上述步骤，依据是否检测到终端发送的切换测试成功响应消息来确定该终端SRVCC切换到目标网络是否成功，通过该方法，不仅解决了相关技术中无法对终端在语音呼叫过程中SRVCC切换到目标网络是否成功无法验证的问题，从而能够有效确认终端在语音呼叫过程中SRVCC切换到目标网络是否成功进行准确验证，有效地完善了SRVCC切换的流程。
为了确保切换流程的准确性，在发送由源网络SRVCC切换到目标网络的切换消息之前，还可以包括：确定终端在源网络发起IP多媒体子系统IMS语音呼叫，并进入振铃阶段。即当前正在进行SRVCC切换。
在判断是否检测到终端在目标网络发送的切换测试成功响应消息时，可以依据具体情景采用适宜的处理方式，例如，可以先判断是否检测到终端在目标网络发送的切换到目标网络成功的切换成功消息；在判断结果为是的情况下，再判断是否检测到终端在目标网络发送的与目标网络链接建立成功的链接确认消息；在判断结果为是的情况下，确定检测到终端在目标网络发送的切换测试成功响应消息。只有上述两次判断结果均为成功的情况下，才确定检测到终端在该目标网络发送的切换测试成功响应消息，即才确定终端SRVCC切换到网络切换成功。
为了在一定程度上确保判断是否检测到终端在目标网络发送的目标网络链接建立成功的链接确认消息判断的准确性，在判断是否检测到终端在目标网络发送的与目标网络链接建立成功的链接确认消息之前，可以先确定终端与目标网络完成临时移动用户标识码(International Mobile Subscriber Identification Number，简称为IMSI)的重分配。另外，在判断是否检测到终端在目标网络发送的与目标网络链接建立成功的链接确认消息之前，还可以依据终端发送的用于挂起通用分组无线业务GPRS的请求挂起过期的GPRS。
另外，为确保之后能够有效检测到终端在目标网络发送的切换测试成功响应消息，并不受一些测量外因的影响，在发送由源网络SRVCC切换到目标网络的切换消息之前，还可以先调整目标网络的信号强度至满足终端上报测量报告。之后，接收到终端上报的测量报告，依据测量报告发送由源网络SRVCC切换到目标网络的切换消息。
在本实施例中还提供了一种网络切换处理装置，该装置用于实现上述实施例及优选实施方式，已经进行过说明的不再赘述。如以下所使用的，术语“模块”可以实现预定功能的软件和/或硬件的组合。尽管以下实施例所描述的装置较佳地以软件来实现，但是硬件，或者软件和硬件的组合的实现也是可能并被构想的。

针对相关技术中，不能对终端支持SRVCC切换的能力进行验证，在本实施例中，提供了一种移动LTE通信网络中语音呼叫连续性的处理方法，即确认LTE IMS语音呼叫振铃阶段SRVCC切换到GSM网络的成功的确认方法，该方法包括：通过检测终端在GSM网络发送切换完成消息和链接确认消息来确定IMS语音呼叫SRVCC切换到GSM网络成功。例如，可以如果终端发送了切换完成确认消息且在随后请求建立链接成功并发送链接确认消息，则认为该IMS语音呼叫SRVCC切换到GSM网络成功。下面对该方案进行说明。
在本发明实施例中给出了一种在LTE网络中IMS语音呼叫在振铃阶段SRVCC切换到GSM网络中的测试方法，包括以下操作：(1)终端在LTE网络发起IMS语音呼叫，并进入振铃阶段；(2)网络发送从LTE网络切换到GSM网络的消息；(3)检测终端是否发送切换到GSM网络成功的消息，如果未发送测试失败，如果发送则继续后续处理；(4)网络发送链接消息到终端；(5)检测终端是否发送链接确认消息。如果发送测试成功，否则测试失败。
上述步骤(1)中的终端在LTE网络发起IMS语音呼叫，并进入振铃阶段是指终端收到网络发送的对PRACK消息的响应200 OK消息。
上述步骤(2)中的网络发送从LTE网络切换到GSM网络的消息，需要网络先发送无线资源链接重配置消息配置对其他模式网络的测量。

在上述步骤(4)中的网络发送链接消息到终端之前，终端需要与网络完成TMSI重新分配流程。
在上述确认LTE IMS语音呼叫振铃阶段SRVCC切换到GSM网络的成功的确认方法中，通过检测终端在GSM网络发送切换完成消息和链接确认消息来确定IMS语音呼叫SRVCC切换到GSM网络成功。需要说明的是，上述网络可以为测试仪器模拟的系统模拟器。
