摘　　要：提出双卡双VoLTE是未来双卡手机的演进方向的观点,从双卡双VoLTE手机的需求出发,通过将双卡双VoLTE终端与目前六模全网通终端进行对比,引出双卡双VoLTE在IMS外网接入、双LTE待机、来回监听等方面面临的技术挑战及解决方案,最后对双卡双VoLTE终端的演进进行了展望,提出LL双待将是实现双卡双VoLTE终端较为可行的技术方案。It holds in the paper that the dual card dual VoLTE is the evolution direction of the dual card mobile phone in the future. According to requirements of the dual card dual VoLTE mobile phone, the dual card dual VoLTE terminal was compared with the six-mode full Netcom terminal, the technical challenge and solution faced by the dual card dual VoLTE in 1MS external network access, dual LTE standby and two-way monitoring were introduced. Finally, the evolution of the dual card dual VoLTE terminal was looked ahead to propose that LL dual standby will be the feasibly technical solution to realize the dual card dual VoLTE terminal.
