Title:
CONTROL METHOD FOR TERMINAL NETWORK CONNECTION, AND MEDIUM AND CHIP THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/233301
Kind Code:
A1
Abstract:
The present application relates to the field of mobile communications. Disclosed are a control method for a terminal network connection, and a medium and a chip therefor. The control method of the present application comprises: a terminal detecting that the link quality of a data link of the terminal does not meet a set quality condition; where the terminal does not activate a dual-connectivity function and is not in a call state, the terminal disconnecting a connection with a 4G network in an access network, and where the terminal generates data service requirements or signaling triggers connection establishment, the terminal re-requesting to be connected to a 5G network and the 4G network in the access network; and where the terminal has activated the dual-connectivity function, the terminal disconnecting the connection with the 5G network in a first 5G serving cell, and re-establishing the connection with the 5G network in a second 5G serving cell. By means of the control method of the present application, under a different network architecture, data transmission between a terminal and a network can be restored by changing a network connection means; moreover, where a call of the terminal remains not disconnected, the data transmission between the terminal and the network is restored, so as to improve the data transmission quality.
