CROSS-REFERENCE TO RELATED APPLICATIONS

This application is based on and claims priority to Chinese Patent Application No. 201910904611.1, filed on Sep. 24, 2019, the entire contents of which are incorporated herein by reference.

BACKGROUND

5G new radio (NR) is a 5G standard for a new Orthogonal Frequency Division Multiplexing (OFDM)-based air interface. 5G NR is introduced relative to a 5G core network. In the 5G era, the NR and the core network each evolves to 5G independently. The evolution of 5G NR architecture is divided into non-standalone (NSA) and standalone (SA). At present, the domestic 5G NSA uses a 4G core network and an LTE and 5G NR dual connection, that is, uses the existing LTE network to deploy 5G, so as to meet the needs of rapid 5G deployment.

SUMMARY

This Summary is provided to introduce a selection of aspects of the present disclosure in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used to limit the scope of the claimed subject matter.

Aspects of the disclosure provide a method for accessing a fifth generation (5G) network, implemented by a terminal. The method includes acquiring frequency point information by performing frequency point scanning in an operating band belonging to an operator of the 5G network; selecting a 5G-supported frequency point used by the operator from the frequency point information; and performing a cell registration process through a cell with the 5G-supported frequency point to access the 5G network.

In an example, when selecting the 5G-supported frequency point used by the operator from the frequency point information, the method further includes selecting a scanned frequency point having maximum signal energy from the frequency point information to perform the cell registration process through a cell with the selected frequency point to access the 5G network.

According to an aspect, the method further includes generating a frequency point list; and adding a 5G-supported frequency point used by each operator to the frequency point list.

According to another aspect, the method further includes setting a scanning priority of a band comprising the 5G-supported frequency point and belonging to the operator to high.

According to yet another aspect, the method further includes, after accessing the 5G network, acquiring a 5G-supported frequency point used for accessing the 5G network; and updating a frequency point list based on the acquired 5G-supported frequency point.

According to yet another aspect, the method further includes acquiring the 5G-supported frequency point used by the operator from the frequency point list through a radio resource control (RRC) module of the terminal.

Aspects of the disclosure also provide a device for accessing a fifth generation (5G) network, located in a terminal. The device includes a processor and a memory configured to store instructions executable by the processor. The processor is configured to acquire frequency point information by performing frequency point scanning in an operating band belonging to an operator of the 5G network; select a 5G-supported frequency point used by the operator from the frequency point information; and perform a cell registration process through a cell with the 5G-supported frequency point to access the 5G network.

Aspects of the disclosure also provide a non-transitory computer-readable storage medium storing instructions that, when executed by a processor of a mobile terminal that is configured to access a 5G network, cause the mobile terminal to acquire frequency point information by performing frequency point scanning in an operating band belonging to an operator of the 5G network; select a 5G-supported frequency point used by the operator from the frequency point information; and perform a cell registration process through a cell with the 5G-supported frequency point to access the 5G network.

It is to be understood that both the foregoing general description and the following detailed description are illustrative and explanatory only and are not restrictive of the present disclosure.
