Here, the band priority information includes priorities of two or more bands. Specifically, the frequency band priority information may include a priority of each frequency band in a full frequency spectrum in the mobile communication system, or only include a priority of at least one frequency band supported by the terminal device itself.
Specifically, when the frequency band priority information includes the priority of each frequency band in the full spectrum, the obtaining of the frequency band priority information may include: receiving frequency band priority information actively issued by network equipment; or, a priority request is sent to the network equipment, and the network equipment issues frequency band priority information responding to the priority request; and receiving frequency band priority information issued by the network equipment. Further, the terminal device may query the frequency band priority information according to at least one frequency band supported by the terminal device, and determine a priority corresponding to the at least one frequency band.

That is to say, the terminal device may determine the priority of at least one supported frequency band from the priority of each frequency band in the full frequency band acquired by the network side; or, the terminal device determines at least one frequency band supported by itself, then queries the priority of the at least one frequency band supported by itself from the network side, and only obtains the priority of the at least one frequency band supported by itself from the network side.
Here, the at least one frequency band to be searched by the terminal device is the at least one frequency band supported by the terminal device.
In some embodiments, the communication network to which the terminal device is connected is a 5G network, and the frequency band supported by the corresponding terminal device is a 5G New Radio (NR) frequency band. For example, the priority in the frequency band priority information is, in order from high to low, a millimeter wave frequency band, a 4.9GHz frequency band, a 3.5GHz frequency band, a 2.6GHz frequency band, and a 1800MHz frequency band.

Further, based on the priority of the at least one frequency band, sequentially searching the frequency points in the at least one frequency band according to the sequence of the frequency band priorities from high to low; and controlling the terminal equipment to reside in the target cell meeting the cell residence condition on the target frequency point.
In practical application, the target frequency point is a frequency point with signal intensity greater than the intensity threshold. For example, the frequency point with the signal intensity greater than the intensity threshold value searched for the first time is taken as the target frequency point, or the frequency point with the highest priority is taken as the target frequency point from a plurality of frequency points with the signal intensities greater than the intensity threshold value searched for.
After the target frequency point is determined, cell search is carried out on the target frequency point, the searched cell is measured, residence condition judgment is carried out on the cell according to the measurement result, if the residence condition is met, the terminal resides in the cell, and if the residence condition is not met, the terminal continues to search the next cell.
The residence conditions may include at least one of: a cell with a signal strength greater than a strength threshold, the cell not being a forbidden cell; a Tracking Area (TA) to which the cell belongs does not belong to any one of the forbidden TA lists of the PLMN to which the cell belongs; the cell conforms to the cell selection S criteria.

Therefore, searching is carried out according to the sequence from the high frequency band to the low frequency band, the terminal equipment is guaranteed to reside in the high frequency band cell to the greatest extent, more network resources can be obtained to carry out data transmission, the internet speed is improved, the terminal equipment resides in the high frequency band cell, the terminal equipment needs smaller transmitting power, and power consumption can be reduced.
On the basis of the foregoing embodiment, a more detailed cell selection method is further provided, and fig. 2 is a second flowchart of the cell selection method in the embodiment of the present application, and as shown in fig. 2, the method includes:
step 201: acquiring frequency band priority information; wherein, the priority of the high frequency band in the frequency band priority information is higher than the priority of the low frequency band;
after the terminal device is powered on and resides, the operator sends the desired access technology selection and the frequency band priority information to the terminal through an air interface, and the terminal stores the received information in the terminal or a user card (such as an SIM card or a USIM card). When the subsequent terminal carries out frequency band searching and network selection, sequential searching is carried out according to the frequency band priority information, the searching strategy is more definite, the network searching time of the mobile terminal is shortened, and the use experience of a user is improved.
Step 202: determining at least one frequency band supported by the terminal equipment;
in practical application, communication network parameters of a Subscriber Identity Module (SIM) of a terminal device are acquired; at least one frequency band supported by the terminal device is determined based on the communication network parameters.
Here, the communication network parameter includes region attribute information and a preset identification code of the user identification unit. For example, the region attribute information may be represented by a Public Land Mobile Network (PLMN), the preset identifier may be an Integrated Circuit Card Identifier (ICCID) in the SIM card, and the ICCID is unique hardware identification information of the SIM card. According to the communication network parameters, the frequency bands of at least one communication network supported by the terminal device can be determined.
Specifically, the home operator with the SIM card inserted is judged, and search frequency band optimization is carried out according to the networking characteristics of the operator, so that the purpose of accelerating cell search speed is achieved.
For example, the authorized frequency bands of the current phase 5G of the mobile operator a are N41(2515MHz-2675MHz) and N79(4800MHz-4900MHz), and if the currently inserted SIM card is the card of the mobile operator a, the NR frequency band in the priority list is used to intersect with the frequency band supported by the mobile operator a, so as to accelerate the search speed and avoid time waste in searching on the frequency band not supported by the operator.
Step 203: taking at least one frequency band supported by the terminal equipment as at least one frequency band to be searched by the terminal equipment;
here, the frequency band range supported by the terminal device is used as the search range of the frequency band, so that the search range of the frequency band can be effectively reduced, and time waste in searching on the frequency band not supported by the terminal device is avoided.
Step 204: determining the priority of at least one frequency band to be searched by the terminal equipment from the frequency band priority information;
in practical applications, when the frequency band priority information includes the priority of each frequency band in the full spectrum, the obtaining of the frequency band priority information may include: receiving frequency band priority information actively issued by network equipment; or, a priority request is sent to the network equipment, and the network equipment issues frequency band priority information responding to the priority request; and receiving frequency band priority information issued by the network equipment. Further, the terminal device may query the frequency band priority information according to at least one frequency band supported by the terminal device, and determine a priority corresponding to the at least one frequency band.
When the frequency band priority information only contains the priority of at least one frequency band supported by the terminal device, acquiring the frequency band priority information, including: determining at least one frequency band supported by the terminal equipment; sending at least one frequency band supported by the terminal equipment to network equipment so that the network equipment queries and returns the priority of the at least one frequency band; and receiving the frequency band priority information sent by the network equipment.
That is to say, the terminal device may determine the priority of at least one supported frequency band from the priority of each frequency band in the full frequency band acquired by the network side; or, the terminal device determines at least one frequency band supported by itself, then queries the priority of the at least one frequency band supported by itself from the network side, and only obtains the priority of the at least one frequency band supported by itself from the network side.
In other embodiments, the frequency band priority information may be a default priority of a different frequency band pre-stored in the terminal device.
Step 205: based on the priority of the at least one frequency band, sequentially searching the frequency points in the at least one frequency band according to the sequence of the frequency band priorities from high to low;
in practical application, searching for a frequency point in the at least one frequency band includes: acquiring the priority of a frequency point in a first frequency band; the first frequency band is any one of the at least one frequency band; and based on the priority of the frequency points in the first frequency band, sequentially scanning the frequency points in the first frequency band from high to low according to the priority of the frequency points. Here, the first frequency band is one frequency band of at least one frequency band.
That is to say, according to the priority of at least one frequency band, the frequency band with the highest priority is searched first, when searching for a frequency point, the frequency band can be searched according to the priority of the frequency point or according to the signal intensity of the frequency point, a suitable frequency point is searched to complete cell residence and the search is stopped, if no suitable frequency point is searched, the frequency band with the second priority is searched until a suitable frequency point is searched to complete cell residence.
In practical application, the target frequency point is a frequency point with signal intensity greater than the intensity threshold. For example, the frequency point with the signal intensity greater than the intensity threshold value searched for the first time is taken as the target frequency point, or the frequency point with the highest priority is taken as the target frequency point from a plurality of frequency points with the signal intensities greater than the intensity threshold value searched for.
Step 206: and controlling the terminal equipment to reside in the target cell meeting the cell residence condition on the target frequency point.
In practical application, after a target frequency point is determined, cell search is performed on the target frequency point, the searched cell is measured, a residence condition of the cell is judged according to a measurement result, if the residence condition is met, a terminal resides in the cell, and if the residence condition is not met, the terminal continues to search a next cell.
The residence conditions may include at least one of: the signal strength is greater than the strength threshold, the cell is not a forbidden cell; a Tracking Area (TA) to which the cell belongs does not belong to any one of the forbidden TA lists of the PLMN to which the cell belongs; the cell conforms to the cell selection S criteria.
The signal strength of the cell includes at least one of: reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), Signal to Interference plus Noise Ratio (SINR), and Received Signal Strength Indication (RSSI).
On the target frequency point, the physical layer firstly searches the strongest cell and reads the system information of the cell according to the cell searching process, the UE evaluates whether the cell is a proper cell according to the S criterion, and once the proper cell is found, the cell selecting process is terminated. If the cell is not a suitable cell, the RRC requires the physical layer to search for the next strongest cell, and so on, until a suitable cell is found and camped on.
Therefore, searching is carried out according to the sequence from the high frequency band to the low frequency band, the terminal equipment is guaranteed to reside in the high frequency band cell to the greatest extent, more network resources can be obtained to carry out data transmission, the internet speed is improved, the terminal equipment resides in the high frequency band cell, the terminal equipment needs smaller transmitting power, and power consumption can be reduced.

step 303: analyzing a target cell on a target frequency point;
step 304: judging whether the target cell meets the cell residence condition; if so, go to step 305; if not, go to step 306;
specifically, a cell with the strongest signal is searched on a target frequency point, if the cell meets a cell residence condition, the cell is selected to reside, otherwise, the cell with the strongest signal in the next frequency point is searched until a suitable cell is searched for residence.
