Referring to fig. 1, fig. 1 is a first flowchart of a network searching method according to an embodiment of the present disclosure. The method comprises the following specific processes:
In some embodiments, when the terminal device moves from a first Network area to a second Network area belonging to a different operator Network from the first Network area, a search through a PLMN (Public Land Mobile Network) is required so that the terminal device can be normally used in a Network connection state. The PLMN searching process is that the terminal scans the PLMN information of the current area to generate a PLMN list for the terminal to use, the list comprises information such as frequency points, PLMN identification and the like, and the terminal can register the PLMN according to the information to complete the network access process.
And step 102, searching a network of a preset frequency band according to the network searching instruction, wherein the network of the preset frequency band is a network of a first searching frequency band indicated by the network searching instruction, and the frequency range of the preset frequency band is 3300 megahertz to 4200 megahertz.
In some embodiments, searching for a network in a preset frequency band according to the network search instruction includes: determining a candidate network frequency band set according to the network search instruction; screening out a network with a preset frequency band from the candidate network frequency band set; and taking the network of the preset frequency band as the network of the first search frequency band indicated by the network search instruction.
In some embodiments, the candidate network frequency band set may be a frequency band set composed of all frequency bands included in a 2G, 3G, 4G or 5G network communication system.
In some embodiments, GSM (Global System for Mobile Communications) is considered a second generation (2G) Mobile phone System, which may include 850MHz (Mega Hertz, MHz), 900MHz, 1800MHz, and 1900MHz bands; UMTS (Universal Mobile telecommunications system ) belongs to the third generation (3G) Mobile phone technology, and the UMTS system may include frequency bands of 850MHz, 900MHz, 1900MHz, 2100MHz, and the like; LTE (Long Term Evolution ) is a Long Term Evolution of UMTS technical standards established by 3GPP organizations, that is, a fourth generation (4G) network communication system is generally defined, and frequency bands used for uploading and downloading commonly used in the LTE system may be 2570MHz-2620MHz, 1880MHz-1920MHz, 2300MHz-2400MHz, and 2496MHz-2690 MHz; while the air interface of the fifth generation (5G) mobile communication technology is NR (new radio), i.e. 5G access network, the 5G NR system includes two large Frequency ranges (Frequency Range, FR), FR1 has a Frequency Range of 450MHz-6000MHz, and FR2 has a Frequency Range of 24250MHz-52600 MHz.
In some embodiments, the network search process of the PLMN generally includes searching from 5G NR to LTE, then UMTS, and finally GSM frequency bands by frequency band, in order to enable the terminal to quickly search for a matching PLMN, a network in a preset frequency band may be selected from 5G NR as a preferred search frequency band, and the frequency band may be applicable to a wider area.
For example, the frequency ranges of 5G NR commonly used in China are 2496MHz-2690MHz, 3300MHz-3800MHz and 2496MHz-2690MHz, the frequency ranges of 5G NR commonly used in Japan are 3300MHz-4200MHz, 3300MHz-3800MHz and 4400MHz-5000MHz, and the frequency range of 5G NR commonly used in Korean is 3300MHz-3800MHz, and compared with the known frequency range of 3300MHz-3800MHz, the frequency range of 3300MHz-4200MHz includes the frequency range of 3300MHz-3800MHz, so that the frequency range of 3300MHz-4200MHz can be preferentially selected as the network for searching the frequency band in the first batch.
In some embodiments, obtaining the first set of frequency band information that supports searching in the cellular data cell in which the current location is located may include: acquiring public land mobile network information of a cellular data cell where a current position is located, wherein the public land mobile network information comprises a mobile country code and a mobile network code; and acquiring a first frequency band information set supporting search of a cellular data cell where the current position is located according to the mobile country code.

In some embodiments, the terminal itself has a frequency band set supporting search, and there is usually a description (Bands 38, 39, 40, 41) in the specification of the terminal device, where "Bands" refers to the frequency band information supported by the terminal, "38", "39", "40", "41" refers to the frequency band numbers, and each frequency band number corresponds to a corresponding frequency band range, "Bands 38" is the frequency band division mode of the 4GLTE system, and the frequency band range is 2570MHz-2620MHz, "Bands 39" is 1880MHz-1920MHz, "Bands 40" is 2300MHz-2400MHz, and Bands41 "is 2496MHz-2690 MHz. Other communication systems such as GSM, UTMS, and 5G NR also have their own frequency band division modes, which is the frequency band information set, i.e. the second frequency band information set, that is, the terminal supports searching.
And step 104, obtaining a target frequency band information set according to the first frequency band information set and the second frequency band information set.
In some embodiments, obtaining the target frequency band information set according to the first frequency band information set and the second frequency band information set may include: comparing the frequency band information in the first frequency band information set and the second frequency band information set to obtain a comparison result; and extracting frequency band information existing in both the first frequency band information set and the second frequency band information set from the comparison result to obtain a target frequency band information set.
In some embodiments, the definition manner of the first frequency band information set and the second frequency band information set can be known through step 103, and in order to reduce the influence of unnecessary frequency bands on the search time in the PLMN search process, all frequency band information in the first frequency band information set and the second frequency band information set may be compared, in the comparison process, frequency bands existing in the first frequency band information set and the second frequency band information set at the same time are screened out, and such frequency band information is grouped into a set to obtain a target frequency band information set.
For example, the frequency band supported by the current location corresponding to the MCC may be a GSM system: 850MHz, 900MHz, 1800MHz and 1900MHz, UMTS system: 850MHz, 900MHz, 1900MHz, and 2100MHz, LTE system: 2570MHz-2620MHz, 1880MHz-1920MHz, 2300MHz-2400MHz and 2496MHz-2690MHz, 5G NR system: 2496MHz-2690MHz, 3300MHz-3800MHz, and 2496MHz-2690 MHz; the frequency band supported by the terminal device may be a GSM system: 850MHz, 900MHz, 1800MHz and 1900MHz, UMTS system: 900MHz, 1900MHz and 2100MHz, LTE system: 2570MHz-2620MHz, 2300MHz-2400MHz and 2496MHz-2690MHz, 5G NR system: 3300MHz-3800MHz and 4400MHz-5000 MHz. Therefore, by comparison, the obtained target frequency band information set is the GSM system: 900MHz, 1800MHz and 1900MHz, UMTS system: 850MHz, 900MHz, 1900MHz, and 2100MHz, LTE system: 2570MHz-2620MHz, 2300MHz-2400MHz and 2496MHz-2690MHz, 5G NR system: 3300MHz-3800 MHz.
In some embodiments, the target frequency band information set includes at least one frequency band information supporting a search of a public land mobile network, so that the terminal device can complete a network access procedure, and thus can be normally used in a network state.
And 105, selecting a target public land mobile network from the target frequency band information set for connection.
In some embodiments, the target frequency band information set is obtained in step 104, and in the PLMN network search process, the frequency band information in the target frequency band information set may be searched one by one according to a search order of priority, for example, network searches of each frequency band may be performed according to an order of a 5G NR system, an LTE system, a UTMS system, and a GSM system until an optimally matched frequency band is selected, a network corresponding to the frequency band is used as a target public land mobile network, and network connection is completed in the network.
In some embodiments, when the network of the preset frequency band is not searched according to the network search instruction, a preset network search mode is adopted to search the public land mobile network.
In some embodiments, the preset network searching method may be: and then network search of each frequency band is carried out in the total frequency band information set according to the sequence of a 5G NR system, an LTE system, a UTMS system and a GSM system.

In the embodiment, by setting the network of the preset frequency band, the network of the frequency band is preferentially selected to search the network in the network searching process, and the current position and the frequency band information set which is searched and supported by the terminal are screened, so that the searching frequency band can be effectively reduced, and the network searching rate is improved.

In some embodiments, in the PLMN network search process, a candidate network frequency band set is determined according to the network search specification, where the candidate network frequency band set may include a frequency band information set supported by a cellular data cell where a current location is located and a frequency band information set supported by the mobile phone for network search; and then judging whether a network with a preset frequency band exists in the candidate network frequency band set.
In some embodiments, the network of the preset frequency band may be a frequency band set composed of all frequency bands included in a 1G, 2G, 3G, 4G or 5G network communication system. For example, the frequency band information in the 5G NR system may be used as a network of a preset frequency band, where the frequency band range commonly used in each region of the world in the 5G NR system is 3300MHz-4200MHz, and therefore the frequency band range may be used as the network of the preset frequency band.
In some embodiments, the network in the preset frequency band with the frequency band range of 3300MHz-4200MHz is used as the frequency band range that is preferentially searched during the PLMN search of the mobile phone, and is determined based on the frequency band range, so that the search of unnecessary frequency bands can be reduced during the network search of the mobile phone, and the search efficiency can be improved.
In some embodiments, when a network of a preset frequency band is not searched, the mobile phone can only search for a full system and a full frequency band, and the process may be to combine all frequency band information sets supported by a cellular data cell where a current location is located and all frequency band information sets supported by a terminal into a total frequency band information set, and then perform network search for each frequency band in the total frequency band information set according to an order of a 5G NR system, an LTE system, a UTMS system, and a GSM system.

In some embodiments, the process of obtaining the target frequency band information set may be to compare the frequency band information of the first frequency band information set obtained from the current location of the mobile phone and the frequency band information of the second frequency band information set searched by the network supported by the mobile phone, and obtain the frequency band information existing in both sets through a comparison result to form a new frequency band information set, that is, the target frequency band information set.
And step 206, selecting a target public land mobile network from the target frequency band information set for connection.
In some embodiments, the target frequency band information set is obtained in step 104, and in the PLMN network search process, the frequency band information in the target frequency band information set may be searched one by one according to a search order of priority, for example, network searches of each frequency band may be performed according to an order of a 5G NR system, an LTE system, a UTMS system, and a GSM system until an optimally matched frequency band is selected, a network corresponding to the frequency band is used as a target public land mobile network, and network connection is completed in the network.
As can be seen from the above, the network search method provided in this embodiment may first receive a network search instruction when switching from a first network area to a second network area; then, searching according to the network searching instruction, and judging whether a network of a preset frequency band is searched; if the judgment result is negative, searching the public land mobile network by adopting a preset network searching mode; if so, acquiring a first frequency band information set which supports searching in a cellular data cell where the current position is located and acquiring a second frequency band information set which supports searching in the current terminal; then, obtaining a target frequency band information set according to the first frequency band information set and the second frequency band information set; and finally, selecting a target public land mobile network from the target frequency band information set for connection.
