For example, referring to fig. 1, when the terminal device switches from the power-off state to the power-on state or from the non-service state to the service state, a network search instruction may be generated, and then a country code is obtained according to the network search instruction, and then a target frequency band is obtained from a preset frequency band list, and network search is performed according to the target frequency band.
As shown in fig. 2, fig. 2 is a schematic flowchart of a network searching method provided in this embodiment, where the network searching method is applied to a terminal device, and the terminal device may be any intelligent electronic device with a mobile communication function, such as a smart phone, a tablet computer, a notebook computer, smart glasses, a smart bracelet, and the like. The terminal device is configured with a card slot into which a Subscriber Identity Module (SIM) card can be inserted, and the SIM card can be selected from a Universal Subscriber Identity Module (USIM) card, an ESIM card (Embedded-SIM) card, and the like. The mobile network can be configured into a 2G, 3G, 4G, 5G or 6G network according to the user identification card and the communication module of the terminal equipment. The Subscriber identity card stores Home Public Land Mobile Network (HPLMN) information, and the Home Public land Mobile Network information includes an International Mobile Subscriber Identity (IMSI). And after the terminal equipment is started, acquiring the information of the home public land mobile network in the user identity identification card inserted into the card slot. The specific process of the network search method provided by this embodiment may be as follows:
101. and acquiring a network searching instruction.
Before the network search instruction is obtained, the service switching state of the terminal device is monitored, and taking a smart phone as an example, when the smart phone is switched from a non-service state (where the non-service state may be a flight mode or a weak signal) to a network service state, the network search instruction is generated.
In addition, before the network search instruction is obtained, the on/off switching state of the terminal device is detected, and when the smart phone is switched from the off state to the on state, taking the smart phone as an example, the network search instruction is generated.
102. And acquiring the country code of the user identification card in the terminal equipment according to the network searching instruction.
Specifically, the country code, i.e., the Mobile Country Code (MCC), is defined in international telecommunication union e.212, which aims to identify Mobile device bases in telecommunication networks, particularly in Global System for Mobile Communications (GSM) and Universal Mobile Telecommunications System (UMTS). The country code is configured by the International Telecommunications Union (ITU) according to the country, for example, 460 in china. The country code is part of the international mobile subscriber identity, typically stored in a removable subscriber identity card, available in the GSM/UMTS radio modem with the AT command AT + COPS.
103. And acquiring at least one frequency band corresponding to the country code from a preset frequency band list as a target frequency band.
The preset frequency band list comprises frequency bands of operators in different countries. For example, china mobile communication group company (china mobile for short), china union network communication group limited company (china unicom for short) or china telecom group company provides their respective subscriber identity cards, and sets corresponding network frequency bands for the subscriber identity cards provided by themselves, respectively. For different national regions, corresponding network frequency band data is usually configured fixedly; for example, the frequency ranges used by the TD-LTE network of the mobile operator in China are 2320-2370MHz and 2575-2635 MHz; an LTEFDD network of a Unicom operator has uplink frequency bands as follows: 1955 and 1980MHz, the downlink frequency band is as follows: 2145-2170 MHz; in an LTE FDD network of a telecommunications carrier, the uplink frequency band is: 1755 + 1785MHz, and the downlink frequency band is: 1850-. It can be seen that for each country around the world there is an allocated set of frequency band numbers. In the embodiment of the application, the terminal device stores frequency bands of operators in different countries in advance, finds out each frequency band corresponding to a country code after acquiring the country code, and performs network search based on the target frequency band.
And S104, network searching is carried out according to the target frequency band.
To this end, the purpose of limiting the range of the required target frequency band by the country code has been completed, but in order to further increase the speed of the network search, the range of the target frequency band may be further narrowed by the history period, and specifically, the step S104 may include:
1-1, acquiring the current time of the terminal equipment.
1-2, determining the historical period corresponding to the current time.
Specifically, the terminal device needs to store a network search record of each time period within half a year for the user to determine. The length of each time interval can be defined as any time interval such as half an hour, an hour and the like.
1-3, detecting whether a target frequency band matched with the historical time interval exists.
For example, the length of each time period may be defined as half an hour, provided that the current time is 15 pm: and 50, then the historical time period corresponding to the current time is 15:35 to 16:05, and then whether the frequency band searched in the historical time period within more than half a year exists in the target frequency band is detected.
And 1-4, if the target frequency band exists, performing network search on the target frequency band matched with the historical time period.
In this embodiment, the number of the target frequency bands matched with the history time period is multiple, and the step of "performing network search on the target frequency band matched with the history time period" may specifically include:
determining the network signal intensity of each target frequency band matched with the historical time period;
sequencing the target frequency bands according to the strength of the signal strength;
and carrying out network search on the plurality of target frequency bands according to the sequencing order.
Preferably, the target frequency bands can be sequenced from strong to weak according to the strength of the signal strength, so that the subsequent network searching speed is increased.
In addition to further narrowing down the target frequency band by using the historical time period, the target frequency band may also be further narrowed down by using the geographic location, and specifically, the step S104 may include:
and 2-1, acquiring the current geographic position of the terminal equipment.
For example, taking a smart phone as an example, according to a positioning function of the smart phone, a location of the smart phone, that is, a current geographic location of a user using the smart phone is determined.
And 2-2, detecting whether a target frequency band matched with the current geographic position exists.
And 2-3, if the frequency band exists, carrying out network search on the target frequency band matched with the current geographic position.
In this embodiment, the number of the target frequency bands matched with the current geographic location is multiple, and the step of performing network search on the target frequency band matched with the current geographic location may specifically include:
acquiring historical use times of each target frequency band matched with the current geographic position;
sequencing the target frequency bands according to the historical use times;
and sequentially carrying out network search on the plurality of target frequency bands according to the sequencing order.
For example, the historical usage count may refer to the number of times each target frequency band is used within a specified period, wherein the specified period may be the last month or half year set by human.
