Depending on the context, the word "if" as used herein may be interpreted as "at the time of" or "when" or "in response to determining".

[0053] The frequency band range supported by the terminal device is generally the union of the frequency bands required by countries and regions around the world. In related technologies, when the terminal device is stationed on the network, it will scan all the frequency bands supported by the terminal device in turn to determine the first frequency point that meets the stationing conditions. Figure 1 As shown, a flow chart of a method for stationing a terminal device in a stationing process in the related art is shown. Figure 1 As shown, the exemplary embodiment method may include the following steps:

[0054] In step 101, a frequency band is determined from candidate frequency bands that have not been scanned as a target frequency band.

[0055] The frequency band range supported by the terminal device may include, for example, 2G (2nd Generation Mobile Communication Technology) band, 3G (3rd Generation Mobile Communication Technology) band, 4G (4th Generation Mobile Communication Technology) band and 5G (5th Generation Mobile Communication Technology) band. Among them, the 2G band may include, for example, 890-960MHz, 1710-1880MHz and other bands. The 3G band may include, for example, 1920-2170MHz, 824-894MHz and other bands. The 4G band may include, for example, LTE (Long-Term Evolution) Band 1: the bands are 1920-1980MHz and 2110-2170MHz, LTE Band 3: the bands are 1710-1785MHz and 1805-1880MHz, etc. 5G frequency bands may include, for example: 5G NR (New Radio) Band n1: frequency band is 2100 MHz, 5G NR Band n3: frequency band is 1710-1785 MHz and 1805-1880 MHz, etc.

[0056] When the terminal device is stationed on the network, the frequency bands supported by the terminal device can be scanned in sequence. For example, the frequency bands may be scanned in the order of 5G frequency band, 4G frequency band, 3G frequency band, and 2G frequency band. Alternatively, only the 5G frequency band may be scanned, which may be set by relevant staff based on actual conditions, and the present disclosure does not limit this.

[0057] In this example, the terminal device may use the unscanned frequency bands as candidate frequency bands, and then determine a frequency band from the unscanned candidate frequency bands based on the aforementioned scanning rule as the target frequency band for subsequent scanning. For example, the determined target frequency band may be the 890-960 MHz frequency band.

[0058] In step 102, the frequency intervals corresponding to the target frequency band are grouped to obtain multiple groups of frequency intervals.

[0059] After determining the target frequency band, the terminal device can group the frequency intervals corresponding to the target frequency band to obtain multiple groups of frequency intervals. For example, the terminal device can group the frequency intervals corresponding to the aforementioned 890-960MHz frequency band to obtain 7 groups of frequency intervals. Alternatively, the terminal device can also group the frequency intervals corresponding to the aforementioned 890-960MHz frequency band to obtain 9 groups of frequency intervals, which is not limited in the present disclosure.

[0060] In step 103, a group of frequency intervals that is most likely to have a first frequency point satisfying the dwell condition among the multiple groups of frequency intervals that have not been scanned is determined as a target group of frequency intervals.

[0061] Take the aforementioned grouping of the frequency intervals corresponding to the 890-960MHz frequency band to obtain 7 groups of frequency intervals as an example for explanation. The physical layer of the terminal device can determine the probability of the existence of the first frequency point that meets the residence condition in each of the multiple groups of frequency intervals that have not been scanned among the 7 groups of frequency intervals based on a specific algorithm. Then, the terminal device can use the group with the greatest probability of the existence of the first frequency point that meets the residence condition as the target group frequency interval.

[0062] In step 104, a scan is performed to determine whether the first frequency point exists in the target group frequency interval.

[0063] After determining the target group frequency interval, the terminal device may scan the target group frequency interval to determine whether there is a first frequency point that meets the residence condition in the target group frequency interval.

[0064] Exemplarily, the above-mentioned resident conditions may include: the signal quality of the frequency point is greater than or equal to a preset quality threshold, there is no interference signal of other frequency bands near the frequency point, the frequency point is within the coverage of the current network operator, etc. In actual applications, the resident conditions can be set by relevant staff based on actual conditions, and this disclosure does not limit this.

[0065] When it is determined that the first frequency point exists in the target group frequency interval, step 105 is executed.

[0066] When it is determined that the first frequency point does not exist in the target group frequency interval, step 106 is executed.

[0067] In step 105, the first cell corresponding to the first frequency point is camped on.

[0068] When the terminal device determines that the first frequency point exists in the target group frequency interval, the terminal device can reside in the first cell corresponding to the first frequency point. At this time, the terminal device successfully resides in the network.

[0069] In step 106, it is determined whether the plurality of groups of frequency intervals have been scanned.

[0070] When the terminal device determines that the above-mentioned first frequency point does not exist in the target group frequency interval, it can further determine whether the multiple groups of frequency intervals under the target frequency band have been scanned.

[0071] When it is determined that the scanning of the multiple frequency intervals is completed, step 107 is executed.

[0072] When it is determined that the plurality of groups of frequency intervals have not been completely scanned, step 103 is executed.

[0073] In step 107, it is determined whether the candidate frequency band has been scanned.

[0074] After the terminal device determines that the scanning of multiple groups of frequency intervals under the target frequency band is completed, it can further determine whether the scanning of the aforementioned alternative frequency bands is completed.

[0075] When it is determined that the candidate frequency band scanning is completed, step 108 is executed.

[0076] When it is determined that the candidate frequency band has not been scanned completely, the terminal device may continue to scan the next frequency band, and at this time, step 101 may be executed.

[0077] In step 108, the network access fails.

[0078] If the terminal device still cannot stay on the network after scanning the supported frequency bands in sequence, the possible problem is that the terminal device is currently at the edge of the network coverage area and the signal strength is not enough to establish a stable network connection. Or, the network where the terminal device is currently located has a fault or is under maintenance, resulting in the inability to establish a network connection. In this case, you can move the terminal device to an area with better network coverage and try to avoid physical obstacles. Alternatively, you can wait for a while for the network fault to recover.

[0079] As above, the process of scanning the frequency bands supported by the terminal device in sequence when the terminal device is stationed in the network in the related technology is shown. Due to different network devices, such as different base stations, the frequency band range supported is limited. For example, a certain base station only supports the 4G frequency band. At this time, if the terminal device performs a full-band scan when stationed in the coverage range of the base station, for example, scanning the 5G frequency band, 3G frequency band, and 2G frequency band, it will waste too many resources and there will be a problem of slow terminal device stationing speed.

[0080] In view of this, the embodiment of the present disclosure provides a method for logging on to a network, so as to save resources and improve the speed of logging on to a network of a terminal device. The method for logging on to a network according to the embodiment of the present disclosure is described in detail below in conjunction with the accompanying drawings.

[0081] Figure 2 FIG. 1 is a flow chart of a method for staying on the network according to an exemplary embodiment of the present disclosure, and the method can be applied to a terminal device. Figure 2 As shown, the exemplary embodiment method may include the following steps:

[0082] In step 201, a target frequency band list is obtained.

[0083] The target frequency band in the target frequency band list is determined based on a common frequency band in a first frequency band supported by the terminal device and a second frequency band supported by the network device.

[0084] Optionally, the terminal device can obtain the target frequency band list through the following method in the scenario of first card insertion and network access.

[0085] In actual applications, the terminal device can respectively obtain the first frequency band supported by the terminal device and the second frequency band supported by the network device, such as the base station, and then match the first frequency band with the second frequency band to obtain a common frequency band in the first frequency band and the second frequency band, and obtain the target frequency band list based on the common frequency band.

[0086] In an optional example, when the terminal device obtains the second frequency band supported by the network device, it can be based on the following steps: obtaining PLMN (Public Land Mobile Net) information pre-stored on a SIM (Subscriber Identity Module) card installed in the terminal device. Then, based on the PLMN information, the second frequency band is obtained. Specifically, after the terminal device obtains the PLMN information pre-stored on the SIM card, it can obtain the second frequency band based on the PLMN information in a previously preset whitelist.

[0087] As can be seen from the above, the second frequency band supported by the network device is determined based on the PLMN information pre-stored on the SIM card installed in the terminal device, and the first frequency band supported by the terminal device usually does not change. In other words, if the PLMN information pre-stored on the SIM card installed in the terminal device does not change, the target frequency band in the target frequency band list will not change.

[0088] Based on this, after the terminal device obtains the target frequency band list for the first time, the target frequency band list can be pre-stored in the terminal device, and when the frequency band scan is started again, it is determined whether the PLMN information pre-stored in the SIM card installed in the terminal device has changed.

[0089] In an optional example, when it is determined that the PLMN information pre-stored on the SIM card has not changed, the target frequency band list pre-stored on the terminal device can be directly obtained, thereby speeding up the acquisition of the target frequency band list, further improving the network access speed of the terminal device, and enhancing the user experience.

[0090] In another optional example, when it is determined that the PLMN information pre-stored on the SIM card has changed, it is necessary to re-acquire a new second frequency band supported by the network device based on the current PLMN information, and match the first frequency band supported by the terminal device with the acquired new second frequency band to obtain at least one new target frequency band. Finally, based on the determined at least one new target frequency band, the pre-stored target frequency band list is updated. This ensures the accuracy of the target frequency bands in the target frequency band list and avoids unnecessary frequency band scanning.

[0091] In step 202, cell frequency scanning is performed in each target frequency band.

[0092] After obtaining the target frequency band list, the terminal device can sequentially scan cell frequencies in each target frequency band. The specific process of frequency scanning can be found in the description of the above embodiment, which will not be repeated here.

[0093] In step 203, in response to scanning to find a first frequency point that meets the camping condition, camp on a first cell corresponding to the first frequency point.

[0094] In the network stationing method provided by the embodiment of the present disclosure, the terminal device can determine the first frequency point that meets the stationing condition from the common frequency band in the first frequency band supported by the terminal device and the second frequency band supported by the network device. Compared with the related art that needs to determine the first frequency point that meets the stationing condition from all frequency bands supported by the terminal device, unnecessary frequency band scanning can be avoided, saving resources while facilitating rapid network stationing.

[0095] Figure 3 1 is a flow chart of another method for stationing on a network according to an exemplary embodiment of the present disclosure. In this embodiment, the same steps as those in the previous embodiment will be briefly described without further details. For details, please refer to any of the previous embodiments. Figure 3 As shown, the exemplary embodiment method may include the following steps:

[0096] In step 301, a target frequency band list is obtained.

[0097] Due to regulations and operator requirements, each country or region restricts the use of certain frequency bands by terminal devices. For example, Mexico restricts the use of LTE Band 8.

[0098] In order to avoid unnecessary frequency band scanning by the terminal device, in the network stationing method of this example, the terminal device can also obtain the target frequency band list based on the following method:

[0099] A first frequency band supported by the terminal device and a second frequency band supported by the network device are obtained, and then a common frequency band in the first frequency band and the second frequency band is determined. A restricted frequency band is deleted from the common frequency band to obtain at least one of the target frequency bands. Finally, based on the at least one target frequency band, a target frequency band list is obtained.

[0100] The restricted frequency band is a frequency band restricted for use in the area where the terminal is located.

[0101] In an optional example, the terminal device may obtain the restricted frequency band based on the PLMN information pre-stored on the SIM card. Exemplarily, the terminal device may obtain the restricted frequency band based on the PLMN information in a previously preset blacklist.

[0102] In step 302, a frequency band is determined from the un-scanned candidate frequency bands included in the target frequency band list as the target frequency band.

[0103] For the convenience of description, in this example, the frequency bands that have not been scanned in the target frequency band list may be referred to as candidate frequency bands, and the frequency band on which the scanning operation is to be performed may be referred to as the target frequency band.

[0104] In step 102, the frequency intervals corresponding to the target frequency band are grouped to obtain multiple groups of frequency intervals.

[0105] In step 103, a group of frequency intervals that is most likely to have a first frequency point satisfying the dwell condition among the multiple groups of frequency intervals that have not been scanned is determined as a target group of frequency intervals.

[0106] In step 104, a scan is performed to determine whether the first frequency point exists in the target group frequency interval.

[0107] When it is determined that the first frequency point exists in the target group frequency interval, step 105 is executed.

[0108] When it is determined that the first frequency point does not exist in the target group frequency interval, step 106 is executed.

[0109] In step 105, the first cell corresponding to the first frequency point is camped on.

[0110] In step 303, the frequency information of the first frequency is saved.

[0111] After successfully camping on the first cell corresponding to the first frequency, the terminal device can save the frequency information of the frequency.

[0112] In step 304, in response to frequency band scanning being enabled again and the first cell being included in the neighboring cells of the terminal device, an attempt is made to reside in the first cell based on the frequency information of the first frequency.

[0113] When the terminal device starts frequency band scanning again and determines that the neighboring cells of the terminal device include the first cell, it can try to reside in the first cell based on the pre-stored frequency information of the first frequency.

[0114] Since the first frequency point is the frequency point that has been confirmed to meet the residence conditions before, it is possible to preferentially try to reside in the first cell corresponding to the first frequency point, thereby effectively shortening the time required for the terminal device to reside in the network and improving the user experience.

[0115] In step 106, it is determined whether the plurality of groups of frequency intervals have been scanned.

[0116] When it is determined that the scanning of the multiple frequency intervals is completed, step 305 is executed.

[0117] When it is determined that the plurality of groups of frequency intervals have not been completely scanned, step 103 is executed.

[0118] In step 305, it is determined whether the candidate frequency bands included in the target frequency band list have been scanned.

[0119] When it is determined that the candidate frequency bands included in the target frequency band list have been scanned, step 306 is executed.

[0120] When it is determined that the candidate frequency bands included in the target frequency band list have not been completely scanned, step 302 is executed.

[0121] In step 306, a third frequency band is determined based on the first frequency band supported by the terminal device and the target frequency band in the target frequency band list.

[0122] In this example, when the terminal device fails to scan the first frequency point under any target frequency band included in the target frequency band list, the terminal device may determine the third frequency band based on the first frequency band supported by the terminal device and the target frequency band in the target frequency band list.

[0123] Specifically, the terminal device may obtain the third frequency band after deleting the target frequency band from the first frequency band.

[0124] In step 307, cell frequency scanning is performed in each of the third frequency bands.

[0125] The process of performing cell frequency scanning in each third frequency band is similar to the aforementioned process of performing cell frequency scanning in each target frequency band. For details, please refer to the relevant description of the aforementioned steps 102 to 106, which will not be repeated here.

[0126] In step 308, in response to scanning to find a second frequency point that meets the camping condition, camp on a second cell corresponding to the second frequency point.

[0127] When the terminal device scans a second frequency point that meets the residence condition in the third frequency band, it can reside in the second cell corresponding to the second frequency point.

[0128] In this example, when the terminal device fails to scan the first frequency point that meets the residence condition in each target frequency band, it can further perform a full-band scan within the full frequency band range supported by the terminal device, thereby improving the probability of the terminal device successfully staying on the network to a certain extent.

[0129] In the network resident method provided by the embodiment of the present disclosure, the terminal device can obtain the target frequency band after deleting the restricted frequency band from the common frequency band in the first frequency band supported by the terminal device and the second frequency band supported by the network device, and scan the target frequency band to determine the first frequency point that meets the resident condition. Compared with the related art of scanning all frequency bands supported by the terminal device to determine the first frequency point that meets the resident condition, unnecessary frequency band scanning can be avoided. Since frequency band scanning is a process that consumes a lot of power, avoiding unnecessary frequency band scanning can save power consumption and extend the use time of the terminal device.

[0130] For the aforementioned method embodiments, for the sake of simplicity of description, they are all expressed as a series of action combinations, but those skilled in the art should know that the present disclosure is not limited by the described order of actions, because according to the present disclosure, certain steps can be performed in other orders or simultaneously.
