Network switching method and device and mobile terminal

Abstract

The embodiment of the invention discloses a network switching method, which comprises the following steps: when a mobile terminal is in a mode that a first network is closed and a second network is connected, acquiring a radio resource control connection reconfiguration message sent by a base station; if the radio resource control connection reconfiguration message contains a cell measurement request of the first network, performing cell measurement on the first cell based on the cell measurement request to obtain a measurement result, the measurement result comprising a target first cell satisfying a preset reporting condition; the measurement result is sent to the base station, so that the base station generates a radio resource control release message according to the measurement result, and the radio resource control release message comprises a to-be-connected first cell in the target first cell; and acquiring a radio resource control release message sent by the base station, disconnecting the connection with the second network based on the radio resource control release message, and connecting the first cell to be connected. According to the scheme, the problem that the mobile terminal fails to switch from the LTE mode to the SA mode is solved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a network switching method, device and mobile terminal. Background technique [0002] Currently, 5G operators use Non-Standalone (NSA), such as the Option3X architecture. In the non-independent networking scenario, the 4G and 5G modules work simultaneously, resulting in high power consumption. The existing power-saving strategy is: according to the current power, whether to turn off the screen or the current data traffic usage, dynamically turn off and turn on the 5G module. Specifically: the NSA terminal does not need to add 5GSCG, and ignores the NR neighbor cell measurement issued by the LTE anchor station. If the current NSA UE is already in ENDC mode, it can directly release the SCG and report SCG Failure. However, this power-saving strategy has a problem: it does not distinguish between SA neighbor cell measurement and NSA neighbor cell measurement, and ignores the NR ne...
