Abstract

This embodiment provides a network mode switching method and device. The method includes: when the terminal is in the public network mode, acquiring the current state of the terminal; if the current state of the terminal is the connected state, discontinuously receiving CDRX according to the connected state of the terminal information to determine the measurement gap used to measure the private network, wherein the CDRX information includes a discontinuous reception cycle, and at least part of the discontinuous reception cycle is used to send and receive data; within the measurement gap, according to the private network frequency point of the private network Measure the private network, and when the signal quality of the private network reaches the preset condition, switch the terminal from the public network mode to the private network mode, and obtain the measurement gap, that is, the gap during which the terminal does not send and receive data, and perform the measurement within the gap. The private network measurement does not affect the data transmission and reception of the terminal. Through a MODEM and a set of RF front-end, the terminal can be switched from the public network mode to the private network mode.

Description

technical field [0001] The present invention relates to the field of communications, and in particular, to a network mode switching method and device. Background technique [0002] There are two types of networks that carry broadband trunking terminals: private network, referred to as private network, refers to network resources composed of base stations, core networks and service servers; public network, referred to as public network, refers to the public network of the operator's network Resources, such as 3G / 4G, WIFI, etc. [0003] In the prior art, the terminal adopts a dual LTE MODEM solution to implement two independent network accesses. That is, two MODEMs deploy a set of radio frequency front-ends, respectively, to independently complete the measurement of the public network and the private network, and the SIM cards used in the two modes of the public network and the private network are independent. When the dual mode of the public and private network is automatic...
