Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a network search method, a terminal, and a computer-readable storage medium.
Background
Currently, with the popularization of the inter-band carrier aggregation technology, a terminal can receive data on two different frequency bands simultaneously. The main antenna and the auxiliary antenna can still only receive and process signals of the same cell (or a plurality of cells) by adopting the same local oscillator or a plurality of local oscillators in the main path and the auxiliary path. After the terminal is started, full-band search is carried out according to self capacity and setting, and the information of the strongest signal cell on each frequency point is tried to be read.
Currently, there are many optimization schemes, for example, a terminal stores related information in a USIM (Universal Subscriber Identity Module) or a mobile phone, and the information may be used to quickly search a cell first without performing a full-band search. However, the method is limited to hardware implementation, and the terminal needs to search frequency points one by one when searching frequency.
The existing scheme is limited in that the same or a plurality of local oscillators are adopted in the main and auxiliary channels, and the terminal needs to search frequency points one by one during frequency searching, so that the searching time is long, and the searching efficiency is low.
