A network switching method and terminal equipment

Abstract

The invention discloses a network switching method and a terminal device, used for making the terminal device quickly switch to a higher version of communication network after entering a lower versionof communication network. The method comprises the following steps: completing a circuit switching CS domain registration in accessed cells; determining whether the cells to be camped are detected, wherein the version of the communication protocol supported by the cells to be camped is higher than that of the communication protocol supported by the accessed cells; in the case of detecting the cells to be camped, camping to a target cell to be camped in the cells to be camped; and initiating the packet switching PS domain registration in the target cell to be camped. The method enables the terminal device to detect cells to be camped with a better network function in time when accessing a network cell supporting a lower version of communication protocol, and switches the network in time once the cells to be camped are detected to shorten the communication time of the terminal device and the accessed cells, thereby improving the network function of the terminal device and optimizing thenetwork experience.

Description

technical field [0001] The present invention relates to the field of terminals, in particular to a network switching method and terminal equipment. Background technique [0002] With the development and maturity of LTE technology, most terminal devices communicate through the LTE network, and the demand for the GSM network is getting smaller and smaller. The LTE signal in some areas is weak. When the terminal device is disconnected from the LTE network, it will often enter the GSM network and try to reconnect to the GSM network after staying on the GSM network. [0003] However, due to the slow speed of the GSM network, it takes too long for the terminal device to reside in the GSM network after entering the GSM network, so that once the terminal device is disconnected from the LTE network, it needs to wait for a long time to reconnect to the LTE network. The internet. [0004] During the period between when the terminal device enters the GSM network and reconnects to the ...

[0003] However, due to the slow speed of the GSM network, it takes too long for the terminal device to reside in the GSM network after entering the GSM network, so that once the terminal device is disconnected from the LTE network, it needs to wait for a long time to reconnect to the LTE network. network

[0004] During the period between when the terminal device enters the GSM network and reconnects to the LTE network, due to the slow transmission speed of the GSM network, it cannot meet the general Internet needs of users, resulting in poor user experience.
