AI Technical Summary

Problems solved by technology

The problems existing in the registration process are: two network registration processes are required, and the number of network signaling interactions increases, resulting in a waste of air interface resources and an increase in terminal power consumption, which is not conducive to the maintenance of terminal standby time
The problem in the joint registration of the single-card single-standby multi-mode terminal is that the registered 2G / 3G network is determined by the LTE network, and the network determined by LTE is not necessarily the optimal network, which is not conducive to user experience

Abstract

The embodiment of the invention relates to a method for triggering the co-registration of a long term evolution (LTE) single-card dual-standby multimode terminal and the LTE single-card dual-standby multimode terminal, and aims to solve the technical problems of increasing of network signaling interaction times and power consumption of the terminal and air interface resource waste caused by respective registration in an LTE network and a second-generation (2G) / third-generation (3G) network, realize the co-registration in the LTE network and the 2G / 3G network, reduce air interface signaling consumption, reduce the power consumption of the terminal and prolong the standby time of the terminal. The method for the co-registration comprises the following steps that: the terminal determines a location area identifier of the 2G / 3G network in which the terminal is to be registered; and the terminal transmits an attach request message comprising the location area identifier to a mobile management entity of the LTE network to trigger the co-registration of the terminal and the mobile management entity of the LTE network in the LTE network and the 2G / 3G network.

Description

technical field [0001] The embodiment of the present invention relates to the field of communication technology, in particular, a method and terminal for triggering joint registration of an LTE single-card dual-standby multi-mode terminal. Background technique [0002] LTE (Long Term Evolution, 3GPP long-term evolution network) single-card dual-standby multi-mode terminal refers to a terminal that resides in two communication subsystems at the same time, and the two communication subsystems are the LTE communication subsystem and the 2G / 3G communication subsystem. The CS domain (Circuit Switch, circuit switching) of the terminal resides in the 2G / 3G network and is used for voice services; the PS domain (Packet Switch, packet switching) resides in the LTE network and is used for data services. The biggest advantage of LTE single-card dual-standby multi-mode terminals is that because they reside in two communication systems at the same time, they can guarantee their voice ser...
