5G network search method, device and terminal

Abstract

The invention provides a 5G network searching method and device and a terminal. The method comprises the steps that a first frequency point list, a second frequency point list and a third frequency point list are established, the first frequency point list records 5G independent networking adjacent region frequency points, the second frequency point list records 5G frequency points possibly not supporting independent networking, and the third frequency point list records 5G frequency points not supporting independent networking; frequency sweeping is carried out in the 5G independent networking searching stage, and a frequency sweeping result is obtained; after frequency sweeping is completed, the frequency sweeping results are sequenced and filtered according to the first frequency point list, the second frequency point list and the third frequency point list; and receiving the system message according to the sorted and filtered frequency sweeping result. According to the invention, the frequency sweeping result can be optimized in the 5G independent networking searching process, and the 5G independent networking searching efficiency is improved.

Description

technical field [0001] The present invention relates to the field of wireless communication technology, in particular to a 5G network search method, device and terminal. Background technique [0002] Under the 5G SA (Standalone, independent networking) network, there is a separate 5G access network, and the terminal accesses the core network by residing in a matching 5G SA cell. In 5G NSA (Non-Standalone, non-independent networking), the access network is still a 4G access network. When necessary (such as high-speed transmission), the network will maintain an LTE (Long Term Evolution, long-term evolution) connection. Simultaneously establish dual connectivity based on 5G NSA cells. In the actual network deployment, there are 5G cells that support both 5G SA and 5G NSA, and there are also 5G cells that only support SA or only NSA. [0003] Terminals that support 5G SA generally search for 5G SA networks first, but when performing frequency scanning, the frequency points of ...

AI Technical Summary

Problems solved by technology

[0003] Terminals that support 5G SA generally search for 5G SA networks first, but when performing frequency scanning, the frequency points of 5G cells that do not support SA will also be included in the frequency scanning results (only used for NSA dual-connection frequencies under 4G) point)

The terminal cannot directly distinguish which frequency points do not support SA in the frequency scanning results. It has to wait until the subsequent system message receiving process to distinguish the frequency points that do not support SA, resulting in inefficient 5G SA network search, especially in Only areas covered by 5G NSA frequency points
