In the mobile business, the telephony service has been the major source of revenue for most mobile operators. Even with the proliferation of smartphones, the voice service is still considered important by users. For the success of LTE, it is of crucial importance to maintain support for the voice service over the LTE network. The mobile industry has been motivated by the success of the IP multimedia subsystem (IMS) standard, and the richness and flexibility of the IMS architecture provides a reliable framework to enable fruitful multimedia services including a voice service with guaranteed quality of service. The IMS supports IP multimedia applications including voice, messaging, video, conferencing, and blended multimedia services. circuit-switched fallback (CSFB) enables a voice service by reusing an existing CS network for UEs normally camping on LTE for IP services.
