一种双卡双通的通信方法、终端、网络及系统
摘要：
本发明实施例公开了一种双卡双通的通信方法、终端及系统。该方法应用于一种支持双卡双通的终端，该终端包括：射频电路以及分别耦合至射频电路的第一调制解调器和第二调制解调器，其中，第一调制解调器包括：第一IP多媒体子系统IMS模块，第二调制解调器包括：第二IMS模块，该方法包括：第一IMS模块通过第一调制解调器与射频电路，向网络侧的第一网关发送第一接入请求，以请求接入网络侧的第一IMS网络；在第一IMS模块通过第一网关稳定驻留到第一IMS网络的情况下，第二IMS模块通过第一调制解调器与射频电路，向网络侧的第二网关发送第二接入请求，以请求接入网络侧的第二IMS网络。
摘要（英）：

Embodiments of the present invention disclose a dual-card dual-active communication method, a terminal, and a system. The method is applied to a terminal that supports dual card dual active. The terminal includes a radio frequency circuit, and a first modem and a second modem that are separately coupled to the radio frequency circuit. The first modem includes a first IP multimedia subsystem IMS module, and the second modem includes a second IMS module. The method includes: sending, by the first IMS module, a first access request to a first gateway on a network side via the first modem and the radio frequency circuit, to request to access a first IMS network on the network side; and when the first IMS module stably camps on the first IMS network via the first gateway, sending, by the second IMS module, a second access request to a second gateway on the network side via the first modem and the radio frequency circuit, to request to access a second IMS network on the network side.
