CS域和PS域之间的切换方法、切换系统和终端 技术领域
本发明涉及通信技术领域，具体而言，涉及一种CS域和PS域之间的切换方法、一种CS域和PS域之间的切换系统和一种终端。
背景技术
目前移动通信网络已经由2/3G网络向长期演进(Long Term Evolution，LTE)网络发展，LTE系统的核心网只保留了分组(Packet Switched，PS)域，称为演进的分组核心(Evolved Packet Core，EPC)网络，演进的分组可信网络主要包含MME、服务网关(Serving Gate，S-GW)、分组数据网络网关(Packet Date Network Gateway，PGW)三个逻辑实体，LTE系统的无线接入网是演进通用陆地无线接入网络(Evolved Universal Terrestrial Radio Access Network，E-UTRAN)，另外，用户设备也可以通过GSM/EDGE无线接入网络(GSM EDGE Radio Access Network，GERAN)或者通用陆地无线接入网络(Universal Terrestrial Radio Access Network，UTRAN)接入演进的分组核心网络。
相关技术中，LTE网络的数据传输的业务质量远远高于2/3G网络，但是，LTE网络的基站覆盖范围以及通信业务质量均低于2/3G网络，运营商在试图通过LTE网络提高用户在数据传输过程中的使用体验的同时，通常采用2/3G网络支持语音通信业务，这种通信方案即为CSFB(Circuit Switched Fallback，电路回落域)通信方案，这种通信方案采用电路交换(Circuit Switched，CS)进行语音通信业务，诸如呼叫、补充业务等采用2/3G网络，在完成语音通信业务后切换回PS域进行数据通信，有通信业务切换导致的网络域切换造成了网络资源的浪费和语音通信业务的延时、通信中断以及互通率低等问题。
另外，相关技术中，对于采用SVLTE通信方案或者SGLTE通信方案的终端，若检测不到LTE网络，终端会持续地执行搜网操作，这种搜网操作会造成终端不必要的功耗浪费和网络资源的浪费。
因此，如何改进PS域和CS域之间的切换方案以保证通信业务的质量成为亟待解决的技术问题。
