For example, 5G may be set in advance.
The network registration triggering event refers to an event triggering registration to a cell corresponding to the first network type, and may include at least one of a power-on event, a network handover event, or an event of entering a served area from an out-of-service area. A network handover event refers to an event that performs a network type handover, such as an event that switches from a 4G network to a 5G network.
Frequency Band (Frequency Band) refers to a Frequency range of electromagnetic waves, and may include a plurality of frequencies in Hz (hertz), and may be, for example, 3kHz to 30 kHz. The preset frequency band configuration file may be a configuration file preset in the target terminal, and may be stored in a communication module of the target terminal, where the communication module may be a baseband processor, for example. The preset frequency band configuration file may include frequency bands respectively corresponding to different operators in a first network type, where the first frequency band refers to a frequency band corresponding to an operator corresponding to the target terminal in the first network type. The target terminal can directly establish connection with the cell corresponding to the first network type through registering the cell corresponding to the frequency point in the first frequency band, namely, the target terminal is directly accessed into the network corresponding to the first network type. The cell corresponding to the first network type refers to a cell corresponding to a frequency point of the first network type. The target terminal may include a subscriber identity card, and the operator corresponding to the target terminal may be an operator to which the subscriber identity card belongs. The frequency band corresponding to the network type refers to a frequency band supported by the network type, for example, when the network type is 5G, the frequency band corresponding to the network type may include an SA (standard, independent networking) frequency band.

The Subscriber Identity card information may comprise at least one of a Mobile Subscriber Identity for distinguishing subscribers in the cellular network or an integrated circuit card Identity, one for uniquely identifying one Subscriber, which may be, for example, an IMSI (International Mobile Subscriber Identity). An integrated circuit card identification number (ICCID) refers to a SIM card number that uniquely identifies a SIM card.
And S204, acquiring a preset frequency point set of the second network type from the preset frequency point configuration file.
Specifically, the preset frequency point configuration file may be a configuration file preset in the target terminal, and may be stored in firmware of a communication module of the target terminal, where the communication module is, for example, a baseband processor.

When the first network type is 5G and the second network type is 4G, the preset frequency point set may include an EN-DC (LTE _ NR Dual Connection) combination.

Each frequency point in the frequency point set can correspond to different priorities, and the priorities of the frequency points can be determined according to the probability of searching the cell corresponding to the frequency point, for example, the priorities of the frequency points can be in positive correlation with the probability of searching the cell corresponding to the frequency point, the higher the probability of searching the cell corresponding to the frequency point is, the higher the priority of the frequency point is, and otherwise, the lower the priority of the frequency point is.
The second network type may be determined according to needs, for example, may be determined according to at least one of similarity or compatibility with the first network type, for example, a network type with the greatest similarity with the first network type may be used as the second network type, or may be preset, for example, 4G, or may be determined according to a network access degree, the network access degree is used for reflecting a difficulty degree of accessing the network, and the network access degree may be in a negative correlation with the difficulty degree of accessing the network, that is, the greater the network access degree, the less the difficulty degree of accessing the network is, and conversely, the greater the difficulty degree of accessing the network is. The network access degree can be determined by the network coverage degree, the larger the network coverage degree is, the larger the network access degree is, otherwise, the smaller the network access degree is.
In some embodiments, the target terminal may update the preset frequency band configuration file and the preset frequency point configuration file by upgrading a firmware of the communication module. For example, the terminal may obtain the latest version of firmware from the file server at preset time intervals to upgrade the firmware in the communication module. The file server may be a server for managing firmware of the communication module.
In some embodiments, the target terminal may read information of the subscriber identity card, and obtain the preset frequency point set of the second network type from the preset frequency point configuration file according to the information of the subscriber identity card.
S206, selecting a second frequency point corresponding to the first frequency band from the preset frequency point set, and determining a second cell corresponding to the second frequency point.
Specifically, the second cell refers to a cell corresponding to the searched second frequency point. The second frequency point is a frequency point determined from the first frequency band. Determining the second cell corresponding to the second frequency point refers to searching the cell corresponding to the second frequency point, and when the cell corresponding to the second frequency point is searched, the searched cell is taken as the second cell. The target terminal can indirectly establish connection with the cell corresponding to the first network type through the second cell.
In some embodiments, the target terminal may select, according to the priority of the frequency points, a second frequency point corresponding to the first frequency band from a preset frequency point set, for example, the frequency point with the highest priority may be selected from the preset frequency point set, when the target terminal searches for a cell corresponding to the frequency point with the highest priority, the frequency point with the highest priority may be used as the second frequency point corresponding to the first frequency band, and when the target terminal does not search for a cell corresponding to the frequency point with the highest priority, the second frequency point corresponding to the first frequency band may be selected from frequency points with priorities lower than the highest priority in the preset frequency point set.
And S208, when the registration to the second cell is determined, sending the candidate frequency band corresponding to the first network type to the second cell so that the second cell selects and obtains the first frequency point from the candidate frequency band, and configuring network registration information of the target terminal to the first cell corresponding to the first frequency point so as to register the target terminal to the first cell.
Specifically, the candidate frequency band refers to a frequency band of the first network type supported by the target terminal, and the candidate frequency band may include at least one frequency point, and when only one frequency point is included, the candidate frequency band is one frequency point. When determining to register in the second cell, the target terminal may send network configuration information to the second cell, where the network configuration information may carry a frequency band of the first network type supported by the target terminal, that is, a candidate frequency band. The first cell refers to a cell corresponding to the first frequency point. The network registration information may include at least one of function information of the target terminal, security information of the target terminal, or RRC (Radio Resource Control) or Radio bearer configuration.
In some embodiments, the network configuration information may further include network quality information corresponding to each frequency point in the candidate frequency band, where the network quality information refers to information related to the quality of the network and may include information such as signal quality. When the second cell acquires the candidate frequency band, whether the network quality information of the frequency point meets the network quality condition or not can be judged according to the network quality information corresponding to each frequency point in the candidate frequency band, and when the network quality condition is met, the frequency point is determined to be the first frequency point. The network quality condition may include that the signal quality is greater than a preset signal quality, and the preset signal quality may be set as needed. The second cell may configure network registration information of the target terminal to the first cell corresponding to the first frequency point, so as to register the target terminal to the first cell. When the first network type is 5G and the second network type is 4G, if the target terminal is registered in the first cell, the target terminal is registered in a Non-standby (Non-independent networking) network.
In the network registration method, a network registration trigger event corresponding to a first network type is acquired, a first frequency band corresponding to the first network type is determined from a preset frequency band configuration file in response to the network registration trigger event, a preset frequency point set corresponding to a second network type is acquired from the preset frequency point configuration file, a second frequency point corresponding to the first frequency band is selected from the preset frequency point set, and a second cell corresponding to the second frequency point is determined; when the registration to the second cell is determined, the candidate frequency band corresponding to the first network type is sent to the second cell, so that the second cell selects the first frequency point from the candidate frequency band, and network registration information of the target terminal is configured to the first cell corresponding to the first frequency point, so that the target terminal is registered to the first cell.
In some embodiments, as shown in fig. 3, the step S206 selects a second frequency point corresponding to the first frequency band from the preset frequency point set, and determining a second cell corresponding to the second frequency point includes:
s302, acquiring a history registration frequency point corresponding to the first network type, and searching a cell corresponding to the history frequency point.
S304, when the cells corresponding to the historical registration frequency points are not searched, selecting the second frequency points corresponding to the first frequency band from the preset frequency point set, and determining the second cells corresponding to the second frequency points.
Specifically, the history registration frequency point refers to a frequency point corresponding to a first network type of a corresponding cell registered by the target terminal in a history time period, for example, if the frequency point a corresponding to the first network type is registered by the target terminal in the history time period, the frequency point a is the history registration frequency point.
In some embodiments, when a target terminal acquires a network registration trigger event corresponding to a first network type, the target terminal may acquire a history registration frequency point corresponding to the first network type, search a cell corresponding to the history frequency point, select a second frequency point corresponding to a first frequency band from a preset frequency point set when the cell corresponding to the history registration frequency point is not searched, and determine a second cell corresponding to the second frequency point; when the cell corresponding to the history registration frequency point is searched, the target terminal can perform network registration to the cell corresponding to the history registration frequency point. For example, after the user equipment is powered on, or re-enters the served area from the non-served area, the target terminal may first search for a PLMN (Public Land Mobile Network) and a frequency point that are successfully registered last time.
In some embodiments, when a cell corresponding to the history registration frequency point is not searched, the target terminal may search according to a frequency band supported by the target terminal, and when the cell is searched, network registration is performed on the searched cell. For example, when the UE fails to search for the last successfully registered PLMN and frequency point, that is, when a suitable cell cannot be found, the UE may perform full band (full band) frequency sweeping according to the frequency band supported by the terminal.
In the above embodiment, the history registration frequency point corresponding to the first network type is obtained, the cell corresponding to the history frequency point is searched, when the cell corresponding to the history registration frequency point is not searched, the second frequency point corresponding to the first frequency band is selected from the preset frequency point set, the second cell corresponding to the second frequency point is determined, and network registration can be preferentially performed on the cell corresponding to the history registration frequency point, so that the cell corresponding to the first network type can be quickly registered under the condition that the position of the target terminal is not changed, and the network registration efficiency is improved.
In some embodiments, when a cell corresponding to a history registration frequency point is not searched, selecting a second frequency point corresponding to a first frequency band from a preset frequency point set, and determining the second cell corresponding to the second frequency point includes: when the cell corresponding to the history registration frequency point is not searched, searching the cell corresponding to the frequency point in the first frequency band; and when the cell corresponding to the frequency point in the first frequency band is not searched, selecting a second frequency point corresponding to the first frequency band from the preset frequency point set, and determining a second cell corresponding to the second frequency point.
Specifically, the network registration trigger event refers to an event that triggers registration to a cell corresponding to the first network type, that is, the network registration trigger event is intended to register to a cell corresponding to the first network type, so that the target terminal may search for a cell corresponding to a frequency point in the first frequency band before performing indirect network registration according to the frequency points in the preset frequency point set, and when the target terminal searches for a cell corresponding to a frequency point in the first frequency band, network registration may be performed to a cell corresponding to a frequency point in the first frequency band, thereby directly establishing connection with the network of the first network type.
In the embodiment, when the cell corresponding to the history registration frequency point is not searched, the target terminal searches the cell corresponding to the frequency point in the first frequency band, so that when the cell corresponding to the history registration frequency point is not searched, the cell can be preferentially searched according to the frequency point which can be directly accessed to the first network type, and the network registration efficiency is improved.
In some embodiments, the method further comprises: when a second cell corresponding to the second frequency point is not determined, a second frequency band corresponding to the second network type is obtained; and when the cell corresponding to the second frequency band is searched, performing network registration to the cell corresponding to the second frequency band.
Specifically, the second frequency band is a frequency band corresponding to the second network type, and may include a plurality of frequency points supported by the second network type. When the target terminal does not determine the second cell corresponding to the second frequency point, the target terminal cannot be connected to the network corresponding to the first network type through an indirect method, so that when the target terminal can search the cell corresponding to the second frequency band, the target terminal performs network registration to the cell corresponding to the second frequency band when the cell corresponding to the second frequency band is searched, and therefore the target terminal can be rapidly accessed to the network corresponding to the second network type.
In the above embodiment, when the second cell corresponding to the second frequency point is not determined, the second frequency band corresponding to the second network type is obtained; when the cell corresponding to the second frequency band is searched, network registration is carried out on the cell corresponding to the second frequency band, so that the network can be quickly accessed into the network corresponding to the second network type, the phenomenon that the target terminal cannot register the network for a long time due to repeated searching of the second cell corresponding to the second frequency point is avoided, and the network registration efficiency is improved.
In some embodiments, as shown in fig. 4, the frequency points in the preset frequency point set correspond to search priorities, and selecting a second frequency point corresponding to the first frequency band from the preset frequency point set includes:
s402, acquiring the frequency band with the highest searching priority in the preset frequency point set as a target searching frequency point.
Specifically, the search priority may be preset as needed, for example, the search priority may be set according to a probability of searching for the corresponding cell, and the higher the probability is, the higher the search priority is. The target searching frequency point is the frequency point corresponding to the highest searching priority in the preset frequency point set.
S404, searching a cell corresponding to the target searching frequency point, when the cell corresponding to the target searching frequency point is not searched, acquiring a frequency point with a next searching priority corresponding to the target searching frequency point from a preset frequency point set to be used as a next target searching frequency point, repeatedly searching the cell corresponding to the target searching frequency point, when the cell corresponding to the target searching frequency point is not searched, acquiring a frequency point with the next searching priority corresponding to the target searching frequency point from the preset frequency point set to be used as a next target searching frequency point, and until the cell corresponding to the target searching frequency point is searched.
And S406, taking the target searching frequency point of the corresponding cell as a second frequency point corresponding to the first frequency band.
Specifically, the frequency point with the next search priority corresponding to the target search frequency point refers to the frequency point with the largest search priority in each frequency point with the smaller search priority than the target search frequency point in the preset frequency point set. When the cell corresponding to the target searching frequency point is searched, the target searching frequency point can be used as a second frequency point corresponding to the first frequency band.
In the above embodiment, according to the search priorities respectively corresponding to the frequency points in the preset frequency point set, the cell of the frequency point with the higher search priority is searched first, that is, the cell search is performed from the frequency point with the higher possibility (probability) of searching the cell, so that the speed of searching the cell can be increased, and the network registration efficiency can be improved.
In some embodiments, determining the first frequency band corresponding to the first network type from the preset frequency band configuration file includes: acquiring a mobile subscriber identification code corresponding to a target subscriber identification card, and inquiring from a preset frequency band configuration file according to the mobile subscriber identification code; and taking the frequency band corresponding to the inquired mobile user identification code as a first frequency band corresponding to the first network type.
Specifically, the target subscriber identity card is a subscriber identity card in the target terminal, and the mobile subscriber identity code is used for uniquely identifying one subscriber. The target terminal can read the mobile subscriber identification code corresponding to the target subscriber identification card from the target subscriber identification card. Each frequency band in the preset frequency band configuration file may be stored in association with a corresponding mobile subscriber identity, and the target terminal may obtain the first frequency band by querying from the preset frequency band configuration file according to the mobile subscriber identity corresponding to the target subscriber identity.
In the above embodiment, the mobile subscriber identity corresponding to the target subscriber identity card is obtained, and the query is performed from the preset frequency band configuration file according to the mobile subscriber identity; the frequency band corresponding to the inquired mobile user identification code is used as the first frequency band corresponding to the first network type, so that the first frequency band is quickly determined from the preset frequency band configuration file according to the mobile user identification code, and the acquisition efficiency of the first frequency band is improved.
In some embodiments, determining the first frequency band corresponding to the first network type from the preset frequency band configuration file includes: when the preset frequency band corresponding to the mobile subscriber identification code is not inquired, acquiring an integrated circuit card identification code corresponding to the target subscriber identification card, and inquiring from a preset frequency band configuration file according to the integrated circuit card identification code; and taking the frequency band corresponding to the inquired integrated circuit card identification code as a first frequency band corresponding to the first network type.
Specifically, the ic card identification code is used to uniquely identify a subscriber identity card. The target terminal can read the integrated circuit card identification code corresponding to the target subscriber identification card from the target subscriber identification card. Each frequency band in the preset frequency band configuration file may be stored in association with a corresponding integrated circuit card identification code, and the target terminal may obtain the first frequency band by querying from the preset frequency band configuration file according to the integrated circuit card identification code corresponding to the target user identification card.
In some embodiments, the frequency bands queried according to the mobile subscriber identity are not consistent with the frequency bands queried according to the integrated circuit card identity, and in some cases, the accuracy of the frequency bands queried according to the mobile subscriber identity is higher than the accuracy of the frequency bands queried according to the integrated circuit card identity. Therefore, the target terminal can be inquired according to the mobile subscriber identity, and when the preset frequency band corresponding to the mobile subscriber identity is not inquired, the target terminal can be inquired from the preset frequency band configuration file according to the integrated circuit card identity.
In the above embodiment, when the preset frequency band corresponding to the mobile subscriber identity is not queried, the integrated circuit card identity corresponding to the target subscriber identity is obtained, and the query is performed from the preset frequency band configuration file according to the integrated circuit card identity, so that when the frequency band is not queried according to the mobile subscriber identity, the frequency band is queried according to the integrated circuit card identity, and the flexibility of querying the frequency band is improved.
In some embodiments, the target terminal may query from a preset frequency point configuration file according to the mobile subscriber identity, use a frequency point set corresponding to the queried mobile subscriber identity as the preset frequency point set, and when the frequency point set corresponding to the mobile subscriber identity is not queried, the target terminal may obtain an integrated circuit card identity corresponding to the target subscriber identity, query from the preset frequency point configuration file according to the integrated circuit card identity, and use the frequency point set corresponding to the queried integrated circuit card identity as the preset frequency point set.
In some embodiments, as shown in fig. 5, a network registration method is provided, where a terminal is configured with a 5G SA frequency band and an LTE frequency point pref _ earfcn _ list under different PLMNs, the terminal (device) matches the SA frequency band and EN-DC (i.e., LTE pref _ earfcn list) supported by a corresponding operator, and after the terminal reads the ICCID and IMSI information of a SIM card, the terminal performs PLMN selection and cell registration processes, which mainly includes the following steps:
1. when reading the ICCID and IMSI information, the terminal matches the SA frequency band and LTE pref _ earfcn list supported by the operator;
2. the terminal searches the cell through the SA frequency point successfully registered last time, searches the SA cell and initiates registration;
3. when the proper cell cannot be searched in the step 2, frequency sweeping is carried out according to the SA frequency band matched in the step 1, and registration is completed after the proper cell is obtained;
4. after the step 3 fails, the terminal sweeps and configures an LTE frequency point (namely LTE pref _ earfcn list preset by the terminal) of an NR (neighbor number) neighbor cell, LTE registration is completed after a proper cell is searched, and the registered LTE cell can configure the NR neighbor cell so as to register the terminal to an NSA (non-mobile switching) network;
5. and 4, after the failure of the step 4, the UE executes the frequency sweep of the rest LTE frequency bands, and completes the registration after searching a proper cell. The rest LTE frequency bands may include 4G frequency points other than the frequency point in the LTE pref _ earfcn list.
At present, with the freezing of the 5G standard, the 5G network and the terminal thereof are also popularized on a large scale. However, at the initial stage of 5G networking, due to network coverage bottleneck, the time consumed for registering a terminal product in 5G is too long, and even the terminal has no network service for a long time, which seriously affects user experience. Under the Sub 6G frequency band, the bandwidth of the 5G frequency band can reach 100M at most, even can reach 400M under millimeter wave, and the frequency sweep consumption time of the terminal under a certain frequency band can be very long. If the UE cannot register the SA network, the terminal blindly scans LTE, so that the terminal stays on the LTE for a long time and cannot register NSA.
In the above embodiment, by configuring the 5G SA frequency bands and the LTE frequency point pref _ earfcn _ list under different PLMNs, the time for the terminal to register in the 5G network is greatly shortened, and the efficiency for the terminal to register in the 5G network is improved.
