Description

终端、移动管理实体和交换中心、业务处理方法和*** 技术领域
本发明涉及终端技术领域，具体而言，涉及一种终端和一种移动管理实体、一种移动交换中心、一种业务处理方法和一种业务处理***。
背景技术
语音电话回落(CSFB)是LTE(Long Term Evolution，长期演进)使用的一种提供语音服务的技术，其通过指导终端从LTE网络回落到2G或者3G网络提供语音服务。被叫终端在收到MME(Mobility Management Entity，移动管理实体)发出的呼叫后做出响应，MME协同MSC(Mobile Switching Center，移动交换中心))通过eNB指导终端回到2/3G网络，终端在2/3G网络上完成语音呼叫建立流程。
在传统的CSFB方案中，终端在接收到电话呼叫后就会回落到2/3G网络开始电话建立流程，接收SETUP(更新)等OTA(Over-the-Air Technology，空中下载技术)消息。只有通过SETUP消息，被叫终端才能知道呼叫方。而此时即使终端不想接通这通电话，但因为已经回落到了带宽较小的2/3G网络，其在LTE上执行的数据业务，比如视频通话等，都已经受到影响或者直接中断。
因此需要一种新的技术方案，可以根据用户是否接听电话决定是否进行电路域回落，从而在用户不接听电话时，不会对数据业务造成影响，提升用户的使用体验。
发明内容
本发明正是基于上述问题，提出了一种新的技术方案，可以根据用户是否接听电话决定是否进行电路域回落，从而在用户不接听电话时，不会对数据业务造成影响，提升用户的使用体验。
有鉴于此，本发明提出了一种终端，终端包括第一通信模块和第二通信模块，其中所述第一通信模块对应的第一通信网络仅支持数据业务，所述第二通信模块对应的第二通信网络至少支持语音业务，所述终端还包括：呼叫建立单元，在所述终端使用所述第一通信网络进行数据业务时，若接收到来自移动管理实体的呼叫请求，则在所述第一通信网络上进行语音呼叫建立流程；交互单元，接收所述移动管理实体发送的建立所述呼叫请求对应的语音业务所需的第二通信网络的电路资源信息；处理单元，在所述语音呼叫建立流程完成后，若检测到所述终端的接听按钮被选择，则发送接听响应至所述移动管理实体，并根据接收到的来自所述移动管理实体的语音回落信息断开所述第一通信网络的数据业务，使用接收到的所述电路资源信息建立所述第二通信网络的语音业务。
在该技术方案中，在终端在仅支持数据业务的第一通信网络上进行数据业务时，如果接收到呼叫请求，则在第一通信网络上建立语音呼叫建立流程，即在第一通信网络上完成终端和移动交换中心之间的协商，从而在终端上显示来电信息，使用户获知该呼叫，这样，用户可以选择是否接听来电，在用户选择接听按键时，则关闭第一通信网络的数据业务，而在支持该语音业务的第二通信网络上建立该语音业务。这样，在用户接听来电时，才将网络从第一通信网络回落到第二通信网络，而在用户不接听来电时，不会断开第一通信网络，从而在用户不接听来电时，不会对正在进行的数据业务造成影响。同时，由于直接根据已接收到的电路资源信息建立语音业务，即电路资源已经准备好了，这样，回落会很快完成。
其中，第一通信网络可以是LTE网络，第二通信网络可以是2G/3G网络，这样，在终端的用户使用LTE网络进行数据业务时，如果此时接收到移动管理实体发送的呼叫请求，则在LTE网络上进行语音呼叫流程的建立，从而使得在不断开LTE网络的数据业务的同时，可以在终端上显示来电信息，从而由用户决定是否接听该来电。在用户接听时，再从LTE网络回落到2G/3G网络，而在用户不接听时，则不需要进行语音回落，从而使得在用户不接听来电电话时，可以不影响正在进行的数据业务，提升了用户的使用体验。

步骤912，用户接听电话，移动交换中心指导终端执行语音回落。终 端接收到SETUP消息后，就可以将呼叫方号码显示给用户，用户据此决定是否接听。如果用户决定接听，终端将接听请求发送给移动管理实体，移动管理实体将接听请求转发给移动交换中心。移动交换中心在收到接听请求后，将需要回落到的2/3G的基站信息(频段和频率)封装在语音回落消息中通过移动管理实体发送给终端，终端据此消息回落到2G或者3G网络开始语音通话。因为2/3G网络的电路资源已经准备好了，回落会很快完成。
步骤914，如果用户拒绝接听，终端将拒绝电话请求发送给移动管理实体，移动管理实体转发给移动交换中心，移动交换中心释放电路资源。
以上结合附图详细说明了本发明的技术方案，通过本发明的技术方案，通过LTE网络提供2/3G网络的OTA消息的隧道，使终端在LTE网络上完成语音通话的建立流程，获知呼叫方的号码，由此决定是否接听。在不接听的情况下，不影响LTE上的数据业务；如果接听，使用户能够做出一定的操作，安全退出LTE数据业务。
以上所述仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
