[0002] The frequencies used in cell searches by mobile terminals are primarily sourced from historically registered frequencies and a frequency data list stored in a smart card maintained by the terminal. Each frequency record in this frequency data list includes a Mobile Country Code (MCC), a Mobile Network Code (MNC), a communication standard, a frequency value, and the number of successful frequency registrations. Related technologies allow for filtering multiple frequency data records for a region from the frequency data list based on the terminal's region, the operator networks supported by the terminal, and the communication standards supported by the terminal. Mobile terminals can determine a wide range of location information, and using country codes to distinguish between them effectively reduces search time compared to full-band searches. However, for users whose location information changes frequently within a country, the amount of frequency data associated with the same country code is large, potentially requiring the terminal to perform multiple search attempts on multiple frequencies before finding a suitable frequency to reside on and complete the cell search.

[0028] In this embodiment, a cell search processing method running on the above-mentioned computer device is provided. Figure 2 Flowchart of a cell search processing method according to an embodiment of the present application. Figure 2 As shown, the process includes the following steps:

[0029] Step S202, obtaining current location information;

[0030] Step S204: determining a frequency point to be scanned corresponding to the current position information according to a frequency point database, wherein the frequency point database stores a correspondence between frequency points and envelope surfaces, each envelope surface is generated by a plurality of position information, and one envelope surface corresponds to one frequency point;

[0031] In this embodiment, a frequency database is pre-created and continuously updated based on prior knowledge. The frequency database stores the correspondence between frequencies and envelopes. The current location information may fall within multiple envelopes, with each envelope corresponding to a frequency. Therefore, the current location information can correspond to multiple frequencies.

[0032] Step S206: Perform cell search based on the frequency to be scanned.

[0033] Through the above steps S202 to S206, the problem in the related technology that the terminal needs to conduct multiple search attempts on multiple frequency points before finding a suitable frequency point to reside and completing the cell search can be solved. After the frequency points based on location information are screened, some frequency points can be preferentially selected as higher priority frequency points, reducing the number of cell search attempts, improving the efficiency of cell search, and reducing the power consumption of the terminal; finding a suitable cell to reside in and obtain network services more quickly is conducive to improving user experience.

[0034] In an embodiment of the present application, the above-mentioned step S206 may specifically include: adding the frequency points to be scanned to a pre-created list of frequency points to be scanned; performing a cell search based on the list of frequency points to be scanned, and further, determining whether the list of frequency points to be scanned is empty; if the list of frequency points to be scanned is not empty, performing a discrete frequency scan on the frequency points to be scanned in the list of frequency points to be scanned; if the list of frequency points to be scanned is empty, performing a full-band scan.

[0035] In an embodiment of the present application, the above-mentioned step S206 may specifically include: determining the target envelope surface where the current position information is located from all envelope surfaces in the frequency database, wherein the target envelope surface is one or more envelope surfaces; obtaining one or more associated frequency points corresponding to the target envelope surface; and determining one or more associated frequency points as frequency points to be scanned.

[0036] In one embodiment, when the list of frequencies to be scanned is empty, full-band scanning is performed, and frequencies are scanned, whether it is necessary to update the envelope surface corresponding to the frequencies that can be scanned at the current position according to the current position information can be determined by the following method: judging whether the current position information is in the envelope surface corresponding to the frequencies scanned at the current position; if the judgment result is yes, discarding the current position information; adding the position information to the list of position information corresponding to the frequencies to be scanned, and updating the envelope surface corresponding to the scanned frequencies according to the list of position information of the scanned frequencies. Figure 3 is a schematic diagram of the envelope surface generated by the position points associated with the same frequency point according to an embodiment of the present application, such as Figure 3 As shown, the area surrounded by the outer contour formed by all positions in the position information list corresponding to the frequency point to be scanned can be determined as the envelope surface corresponding to the frequency point to be scanned by calculating the contour of the two-dimensional point set; the corresponding relationship between the target frequency point and the envelope surface corresponding to the target frequency point is stored in the frequency point database.

[0037] In another embodiment, when the position information of the frequency point is obtained for the first time, the correspondence between the frequency point and the envelope surface can be stored in the following manner: when the position information list corresponding to the target frequency point is empty, obtain one or more position information of the target frequency point scanned, wherein the target frequency point is any frequency point among all frequency points; add the one or more position information to the position information list corresponding to the target frequency point; determine the envelope surface corresponding to the target frequency point according to the position information list, specifically, determine the area surrounded by the outer contour formed by all positions in the position information list as the envelope surface by calculating the two-dimensional point set contour; store the correspondence between the target frequency point and the envelope surface corresponding to the target frequency point in the frequency point database.

[0038] For newly added location information, whether to update the envelope surface corresponding to the frequency point can be determined in the following way: when the location information list corresponding to the target frequency point is not empty, obtain the target location information of the target frequency point scanned, wherein the target frequency point is any frequency point among all frequency points; if the target location information is in the envelope surface corresponding to the target frequency point, discard the current location information; if the target location information is not in the envelope surface corresponding to the target frequency point, add the target location information to the location information list corresponding to the target frequency point, and regenerate the envelope surface corresponding to the target frequency point according to the location information list corresponding to the target frequency point. Specifically, the area surrounded by the outer contour formed by all positions in the location information list corresponding to the target frequency point can be determined as the envelope surface corresponding to the target frequency point by means of two-dimensional point set contour calculation.

[0039] This solution is not considered for high-speed moving terminals. Therefore, before determining the frequency to be scanned corresponding to the current location information based on the frequency database, it is necessary to eliminate high-speed moving terminals, obtain the current moving speed of the terminal, and determine that the current moving speed is less than the preset speed. That is, only terminals with a speed less than the preset speed can select some frequency points as higher priority to be scanned first after performing the frequency screening action based on the location information, thereby reducing the number of attempts to search the cell, improving the efficiency of the cell search, and reducing the power consumption of the terminal; and finding a suitable cell to reside in and obtain network services faster.

[0040] In another optional embodiment, after the above step S206, if camping on a cell fails, full frequency band scanning is performed.

[0041] In this embodiment, the envelope surface corresponding to multiple position information is determined based on the two-dimensional point set contour calculation method. The contour drawn by the scattered points can be calculated, and the boundary contour of the scattered point distribution area can also be calculated. The specific calculation method will not be repeated here.

[0042] This embodiment provides cell search optimization for terminals. Based on the GPS location information of the wireless terminal, a frequency database associated with the location information is maintained. This location information should be accurate to within 100 meters. As the database expands, when multiple locations are associated with the same frequency, this embodiment generates an envelope from the multiple locations, and all locations within this range are associated with that frequency. For terminals that are not being powered on for the first time and have already undergone an initial cell search and found an available frequency, when the terminal is powered on again or returns to a covered area from a blind spot, it obtains its current location information and prioritizes the frequency associated with the current location information in the maintained frequency database for cell search, thereby quickly finding a suitable cell. This addresses the weaknesses of cell search in related technologies by increasing the priority of certain frequencies in the maintained frequency database. Compared to general cell search, frequencies based on location information can be selected and given a higher priority, reducing the number of cell search attempts, improving cell search efficiency, and reducing terminal power consumption. This allows for faster retrieval of suitable cells for network service, which in turn improves user experience.

[0043] The application environment of this embodiment mainly relies on a wireless communication network system and wireless mobile terminal devices. The wireless communication network system takes a 5G system as an example. The main network devices involved include:

[0044] Wireless mobile terminal: air interface and wireless base station interconnection;

[0045] Base station: provides network services for wireless mobile terminal devices;

[0046] Core network: manages terminals and provides a gateway for communication with the external network.

[0047] The cell search in this embodiment mainly includes:

[0048] Regional information collection: based on the global positioning system GPS;

[0049] Frequency point screening: Based on the terminal's geographic location information, determine all envelope surfaces in the frequency point database that include the current location, then filter out the corresponding location information elements, and add the location information element-associated frequency points to the frequency point table to be searched;

[0050] Envelope surface generation: For scenarios where multiple locations are associated with the same frequency, an envelope surface is generated from these locations using a 2D point set contour calculation method, such as the Graham scanning method. All locations within the envelope surface are associated with the frequency.

[0051] Location information screening: Filter the location information associated with the same frequency point, add the location information that meets the requirements to the location information element list associated with the frequency point, discard the location information that does not meet the requirements, and regenerate the envelope surface associated with the frequency point;

[0052] Cell Search: The main process of cell selection consists of frequency scanning and cell search. After powering on, the terminal first scans the stored frequencies and historical resident frequencies. A discrete sweep is performed on the enumerated frequencies. If no frequencies with energy are found during this process, the reported frequency confirmation information does not include any frequencies, and a full-band sweep is performed, awaiting frequency report confirmation. The stored frequencies are composed of the stored frequencies carried in the sent resident request message, the locally stored PLMN list search, and the frequencies scanned during the previous cell search. Historical resident frequencies are stored locally and globally after a successful resident. They are written to the NV file when the terminal powers off and are only used during the first frequency scan after powering on. Once the reported confirmation information contains frequency information, the cell search process continues, awaiting cell report confirmation. Cell information is sorted by energy level. Upon receiving the cell search confirmation, the system information is read for each element in the obtained cell information list to determine if it is suitable for resident.

[0053] Figure 4 This is a flowchart of a cell search according to an embodiment of the present application. Figure 4 As shown, including:

[0054] Step S401, obtaining current location information. Specifically, when the terminal is powered on or returns to a covered area from a blind area, the current location information is obtained based on GPS technology;

[0055] Step S402: Filter out frequencies to be scanned from a frequency database in memory based on the current position information and generate a list of frequencies to be scanned. Specifically, retrieve position range elements from the frequency database in memory in sequence based on the current position information to determine whether the current position information is within its envelope. If so, retrieve the frequencies associated with the envelope. The current position may belong to multiple envelopes, so multiple associated frequencies may be retrieved to generate a single frequency to be scanned.

[0056] Step S403, determining whether the list of frequencies to be scanned is empty, if the determination result is yes, executing step S406, if the determination result is no, executing step S404;

[0057] Step S404: Perform discrete frequency scanning according to the frequency list to be scanned. If the frequency list to be scanned is empty, it means that the user has not resided in the location range in history, and the full-band frequency scanning action will be directly performed;

[0058] Step S405: determine whether a suitable cell to reside in is found. If the determination result is no, execute step S406; if the determination result is yes, execute step S407;

[0059] Step S406 , performing full-band scanning according to the support capability of the terminal; the support capability of the terminals of different operators may be different, that is, the frequency points at which the terminals of different operators perform full-band scanning may be different.

[0060] Step S407: When a suitable cell is found, the frequency scanning process ends; otherwise, the full-band frequency scanning process continues.

[0061] Figure 5 is a schematic diagram of the positional relationship between the frequency points and the envelope surface according to an embodiment of the present application, such as Figure 5 The figure shows the envelope surfaces associated with three frequencies. The location range (i.e., envelope surface) associated with frequency A is generated based on the terminal's current location at the moment frequency A was scanned, obtained four times (for illustration purposes only). As can be seen from the figure, the location ranges of frequency points A and B overlap, which is consistent with actual conditions.

[0062] The following examples illustrate the embodiments of the present application.

[0063] Figure 6 This is a flow chart of frequency screening according to an embodiment of the present application. Figure 6 As shown, including:

[0064] Step S601: When the terminal is powered on for the first time, the location information list corresponding to the frequency point is empty, and the frequency point database corresponding to the current location information is empty. That is, no frequency scanning process has been performed, the location information list associated with the frequency point is empty, and the frequency point database associated with the current location information is also empty.

[0065] Step S602, obtaining current position information a[X1, Y1];

[0066] Step S603: When the terminal needs to find a suitable cell to reside in and obtain network services, the frequency list to be scanned generated according to the current location information is empty;

[0067] In step S604, the terminal directly performs a full-band scan to obtain the current location information and the scanned frequencies A, B, and C. Scanning three frequencies is only an example, and the number of frequencies may be greater or less.

[0068] Step S605: Add element a to the position information lists associated with frequency points A, B, and C respectively, and generate an envelope surface F1 according to the current position information;

[0069] Step S606, when the terminal is powered on again, obtain the current location information b[X2, Y2];

[0070] Step S607, determining whether the current position information b is within the generated envelope surface F1, if the determination result is yes, executing step S608, if the determination result is no, executing step S609;

[0071] Step S608: Add frequency points A, B, and C to the list of frequencies to be scanned, and scan them first.

[0072] Step S609: The frequency point list to be scanned generated at the current position b is empty, and the terminal performs a full-band scan to obtain the frequency points A, D, and E that can be scanned at the current position;

[0073] Step S610: Add the current position information b to the position list corresponding to the frequency points A, D, and E, and regenerate the envelope surface F2.

[0074] If the current position is in the envelope surface F1, the frequency points A, B, and C associated with them are taken out respectively, added to the list of frequency points to be scanned, and scanned first; if the current position information is not in the envelope surface F1, the terminal performs a full-band scan and obtains the frequency points A, D, and E under the current position information b (the three frequency points here are just for example, and there can be more or less frequency points), and adds element b to the location information list associated with the frequency points A, D, and E respectively; for frequency points D and E, b is the first element, and an envelope surface is generated according to the current position information. For frequency point A, the associated location list contains two elements a and b, and the envelope surface F2 is generated according to the two-dimensional point set contour calculation method such as the Graham scanning method.

[0075] The embodiment of the present application appropriately optimizes the cell search process of a wireless mobile terminal when it is not turned on for the first time, specifically including:

[0076] The wireless mobile terminal can maintain two frequency databases in the memory, one is a normal general frequency database containing stored frequencies and historical resident frequencies, and the other is a frequency database associated with location information; or it can maintain information indicating that a subset of its normal general frequency database containing stored frequencies and historical resident frequencies is associated with location information in other ways.

[0077] When the terminal is powered on for the first time, there is no historical resident frequency or stored frequency information. The full-band frequency sweep process is first performed. At this time, the frequency database maintained by the terminal does not contain any elements. Based on the speed information obtained by the regional information acquisition unit, it is determined whether the current terminal's moving speed is low or high. For terminals in a high-speed moving state, the position changes greatly in a short period of time and is not considered for the time being.

[0078] When the location information of the wireless mobile terminal remains unchanged or is in a low-speed moving state during the first full-band scanning process, the cell information scanned within the communication range of the current location is associated with its location information. The cell information includes basic cell parameters such as the country code MCC, mobile network code MNC, communication standard, and frequency value.

[0079] Location information, such as the current terminal's latitude, longitude, and altitude, is provided by the Global Positioning System (GPS). If a wireless terminal chooses to maintain two databases, a general frequency database (1) contains stored and historical frequency information. A frequency database (2) associated with location information contains each frequency entry and associated location information.

[0080] The elements in the location information list associated with each piece of frequency information in frequency database 2 associated with location information are not unique. Ignoring altitude information, for frequency a, if the location of frequency a is first scanned, it is a geographic location A[X1, Y1] uniquely identified by its longitude and latitude. Geographic location A is added to the location information list associated with frequency a in frequency database 2. If the location of frequency a is scanned again, it is a geographic location B[X2, Y2] uniquely identified by its longitude and latitude. Both A and B are location information elements associated with frequency a. Geographic location B is added to the location information list associated with frequency a in frequency database 2, and the envelope formed by location points A and B is calculated.

[0081] When the element in the location information list corresponding to each frequency point is not 0, a judgment needs to be made for the newly added elements in the list to determine whether the newly acquired location point is within the envelope generated by the existing elements. If it is within the envelope range, it is discarded; otherwise, it is added to the location information list. The following example illustrates that if there are 3 elements in the location information list associated with frequency point a, namely geographic locations A[X1, Y1], B[X2, Y2], and C[X3, Y3], and frequency point a is scanned at geographic location D[X4, Y4], it is calculated whether location point D is within the envelope formed by points A, B, and C. If it is not, geographic location D is added to the location information list associated with the frequency point in frequency database 2, and the envelope formed by points A, B, C, and D is regenerated. Otherwise, the geographic location D information is discarded.

[0082] When the terminal is not powered on for the first time or returns to the coverage area from a blind area, the area information acquisition unit obtains the current location information of the wireless terminal in real time, and selects the frequency data record associated with the location information from the frequency database 2 through the frequency screening module based on the location information, and generates a list of frequencies to be searched based on the screening results.

[0083] The terminal takes frequency data records from the frequency list to be searched in sequence and attempts to search for a cell. When the frequency list to be searched is traversed and no suitable cell is found to reside in, the terminal will directly perform a full-band frequency scan to attempt a cell search.
