Abstract

Embodiments of the present invention relates to a method for triggering joint registration performed by an LTE single-card dual-standby multi-mode terminal, and a terminal, so as to solve a technical problem in the prior art that LTE network registration and 2G/3G network registration are separately performed so the power consumption of the terminal is increased. The joint registration method includes: determining, by a terminal, a location area identity of a 2G/3G network in which registration is to be performed; and, sending, by the terminal, an attach request message to a mobile management entity of an LTE network, where the attach request message contains the location area identity, so as to trigger the joint registration which is in the LTE network and the 2G/3G network and is performed together by the terminal and the mobile management entity of the LTE network.
