技术领域technical field
本发明涉及通信网络技术领域，尤其涉及一种承载电路语音业务的方法及装置。The invention relates to the technical field of communication networks, in particular to a method and device for carrying circuit voice services.
背景技术Background technique
长期演进(Long Term Evolution，LTE)作为下一代移动通信系统重要的技术，也是3G的演进技术，具有高带宽、高移动性、低时延的优点。在现有技术中，LTE网络不支持电路交换域(Circuit Switch Domain，CS域)业务，即LTE网络不支持语音业务。全球移动通信系统(Global System of Mobile communication，GSM)网络和通用移动通信系统(Universal Mobile Telecommunication System，UMTS)网络可以支持语音业务。当采用LTE网络进行语音业务时，通常采用两种方案执行：方案一，在LTE网络的核心网部署IP多媒体子系统(IP Multimedia Subsystem，IMS)，然后采用网络之间互连的协议(InternetProtocol，IP)传输语音，即IP协议传输语音(Voice over Internet Protocol，VoIP)实现语音业务；方案二，当用户驻留LTE网络时，需要将语音业务从LTE网络转回到GSM或者UMTS网络中，以建立语音业务完成语音通话。Long Term Evolution (LTE), as an important technology of the next generation mobile communication system, is also an evolution technology of 3G, and has the advantages of high bandwidth, high mobility, and low delay. In the prior art, the LTE network does not support circuit switched domain (Circuit Switch Domain, CS domain) services, that is, the LTE network does not support voice services. A global system of mobile communication (Global System of Mobile communication, GSM) network and a universal mobile communication system (universal mobile telecommunications system, UMTS) network can support voice services. When an LTE network is used for voice services, two schemes are generally adopted: scheme one, deploying an IP Multimedia Subsystem (IP Multimedia Subsystem, IMS) in the core network of the LTE network, and then adopting an interconnection protocol (Internet Protocol, IP) voice transmission, that is, IP protocol voice transmission (Voice over Internet Protocol, VoIP) to realize the voice service; scheme 2, when the user resides on the LTE network, the voice service needs to be transferred from the LTE network back to the GSM or UMTS network to Set up a voice service to complete a voice call.
然而，通过在核心网部署IMS，使得LTE支持语音业务需要依靠IMS部署，购买和部署IMS设备导致成本较高；另外，将LTE网络转回到GSM或者UMTS网络时，用户在LTE下的语音业务都需要被中断，导致语音业务建立的时延较长。However, by deploying IMS in the core network, LTE supports voice services that need to rely on IMS deployment, and the cost of purchasing and deploying IMS equipment is high; in addition, when the LTE network is transferred back to the GSM or UMTS network, the user's voice services under LTE Both need to be interrupted, resulting in a long delay in voice service establishment.
