[0032] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0033] The frequency scanning method, device, computer-readable storage medium, and electronic device of the embodiments of the present invention are described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0034] The frequency scanning method according to the embodiment of the present invention is used in terminal equipment.

[0035] In the embodiment of the present invention, the terminal device may be a user equipment (UE), such as a mobile phone, a computer, a tablet, etc. It should be noted that the embodiment of the present invention does not limit the type of the terminal device.

[0036] Figure 1 FIG. 1 is a flow chart of a frequency scanning method according to an embodiment of the present invention. Figure 1 As shown, the frequency scanning method may include:

[0037] S101, determining the number and bandwidth of frequency bands to be scanned in a target channel;

[0038] S102, determining a target scanning frequency number of the frequency band to be scanned according to the number of frequency bands, the frequency band width, a first parameter and a second parameter, wherein the first parameter is determined by the cell bandwidth, and the second parameter is determined by the number of base stations within a preset range;

[0039] S103, scanning the frequency points of the frequency band to be scanned based on the target scanning frequency point number.

[0040] In order to enable the terminal device to quickly and accurately search for available cells, the terminal device of an embodiment of the present invention comprehensively determines the target scanning frequency number of the frequency band to be scanned based on the frequency band number and bandwidth of the target channel to be scanned, as well as the cell bandwidth and the number of base stations in the environment where the terminal device is located, so that the terminal device can take into account the time and coverage of the available frequencies and search for available cells quickly and accurately.

[0041] Specifically, different terminal devices support different frequency band scenarios. Some terminal devices support multi-band scenarios, and some terminal devices support locked-band scenarios (single-band scenarios). The frequency band scenarios supported by the terminal devices are different, and the target scanning frequency points of the frequency band to be scanned are determined differently. Therefore, when determining the target scanning frequency points of the frequency band to be scanned, the number of frequency bands and the bandwidth of the frequency band to be scanned of the target channel of the terminal device are determined. At the same time, the first parameter is determined based on the cell bandwidth of the environment in which the terminal device is located, and the second parameter is determined based on the number of base stations in the environment in which the terminal device is located. The number of frequency points (target scanning frequency points) that need to be searched for the frequency band to be scanned is comprehensively evaluated based on the number of frequency bands, the bandwidth, the first parameter, and the second parameter.

[0042] The frequency scanning method of the embodiment of the present invention comprehensively determines the target scanning frequency number of the frequency band to be scanned based on the frequency band number and bandwidth of the frequency band to be scanned of the target channel of the terminal device, the cell bandwidth of the environment in which the terminal device is located, and the number of base stations, so that the terminal device can take into account the time and coverage of the available frequency points and search for available cells quickly and accurately.

[0043] In one embodiment of the present invention, Figure 2 As shown, before determining the number of frequency bands and the frequency bandwidth of the target channel to be scanned, the frequency point scanning method may include:

[0044] S201, after the terminal device is tuned to a supported channel, measuring the signal strength of the supported channel;

[0045] S202: Record a channel whose signal strength is greater than a preset strength threshold as a target channel.

[0046] Specifically, when the terminal device registers to access the cell for the first time, the channel of the terminal device is adjusted to tune the terminal device to the supported channel. After the terminal device is tuned to the supported channel, the signal strength of the supported channel is measured. It is determined whether the signal strength of each supported channel is greater than a preset strength threshold. The channel greater than the preset strength threshold is recorded as the target channel.

[0047] As a specific example, the terminal device measures the RSSI (Received Signal Strength Indicator) of each supported channel. When the terminal device measures the RSSI of each supported channel, a list RSSI containing each channel number of the RSSI measurement value can be created. According to the RSSI measurement values ​​in the list RSSI, the RSSI measurement values ​​greater than the preset strength threshold are determined. Using the list RSSI, the corresponding channel number is determined according to the RSSI measurement value greater than the preset strength threshold, and the target channel is determined according to the channel number.

[0048] It should be noted that RSSI is just a measurement of any energy / power that the terminal device can measure. This measurement does not require any channel coding process. When measuring the RSSI of the channels it supports, the terminal device does not need to know anything about the network, nor does it try to decode or synchronize / reference signals (in LTE (Long Term Evolution)) to detect the physical cell ID. It just measures the power of each channel.

[0049] In one embodiment of the present invention, Figure 3 As shown, determining the target scanning frequency points of the frequency band to be scanned according to the number of frequency bands, the frequency band width, the first parameter and the second parameter may include:

[0050] S301, determining a first target value and a second target value of a first parameter according to a frequency bandwidth, wherein the first target value is smaller than the second target value;

[0051] S302, determining a third target value and a fourth target value of the second parameter according to the number of frequency bands, wherein the third target value is smaller than the fourth target value;

[0052] S303, using a preset scanning frequency formula, determining a first scanning frequency according to the frequency bandwidth, the first target value and the fourth target value, and determining a second scanning frequency according to the frequency bandwidth, the second target value and the third target value;

[0053] S304: Determine a target scanning frequency number according to the number of frequency bands, the first scanning frequency number, and the second scanning frequency number.

[0054] In one embodiment of the present invention, the frequency bandwidth is positively correlated with the first target value and the second target value of the first parameter.

[0055] In one embodiment of the present invention, the expression of the preset scanning frequency point number formula is: Indicates rounding down.

[0056] The first parameter in the embodiment of the present invention is associated with the cell bandwidth and can be set to two levels, and the value corresponding to each level is determined by the bandwidth.

[0057] The second parameter in the embodiment of the present invention is associated with the number of base stations in the environment where the terminal device is located, and can be set to three levels accordingly. The value corresponding to each level can be set to 3, 6, and 9 respectively.

[0058] Specifically, a first target value and a second target value of the first parameter are determined according to the frequency bandwidth, and a third target value and a fourth target value of the second parameter are determined according to the number of frequency bands.

[0059] According to the preset scanning frequency point formula, the ratio of the frequency bandwidth to the first target value is calculated and rounded up, and the calculated integer is multiplied by the fourth target value to obtain the first scanning frequency point.

[0060] According to the preset scanning frequency point formula, the ratio of the frequency bandwidth to the second target value is calculated and rounded up, and the calculated integer is multiplied by the third target value to obtain the second scanning frequency point.

[0061] Since the first scanning frequency number is the ratio of the frequency bandwidth to the first target value and is rounded and multiplied by the fourth target value. The second scanning frequency number is the ratio of the frequency bandwidth to the second target value and is rounded and multiplied by the third target value. The first target value is smaller than the second target value, and the fourth target value is larger than the third target value, so the calculated first scanning frequency number is larger than the second scanning frequency number. In order to quickly and accurately determine the target scanning frequency number of the frequency band to be scanned, an embodiment of the present invention determines the target scanning frequency number of the frequency band to be scanned based on the number of frequency bands and the calculated first scanning frequency number and second scanning frequency number.

[0062] In one embodiment of the present invention, determining the target scanning frequency number according to the number of frequency bands, the first scanning frequency number and the second scanning frequency number may include:

[0063] If the number of frequency bands is equal to 1, the first scanning frequency point number is recorded as the target scanning frequency point number;

[0064] If the number of frequency bands is greater than 1, the second scanning frequency point number is recorded as the target scanning frequency point number.

[0065] Specifically, since the first scanning frequency number is greater than the second scanning frequency number, the number of frequency bands is equal to 1, that is, when the terminal device is in a locked frequency band scenario, especially some frequency bands with small bandwidth (such as band 71, band 72, band 73), the bandwidth is only 5MHz, and the frequency is relatively low (663MHz-450MHz). In order to cover as wide as possible and make full use of frequency resources, the number of configured frequency points will be relatively large. At this time, if as many frequency points as possible cannot be scanned, then effective frequency points may be missed, resulting in failure to access the Internet. In order to make full use of frequency resources, the first scanning frequency point number is recorded as the target scanning frequency point number of the frequency band to be scanned, so as to scan as many frequency points in the frequency band to be scanned as possible.

[0066] Specifically, since the first scanning frequency number is greater than the second scanning frequency number, the number of frequency bands is greater than 1, that is, when the terminal device is in a multi-band scenario, there are a large number of frequency points in each frequency band. In order to prevent the scanning frequency points from taking too much time, resulting in a slow network registration process, the second scanning frequency point number is recorded as the target scanning frequency point number, so that the terminal device can quickly scan all the frequency points in the frequency band to be scanned.

[0067] In one embodiment of the present invention, before determining the target number of scanning frequency points of the frequency band to be scanned according to the number of frequency bands, the frequency band width, the first parameter and the second parameter, the frequency point scanning method may further include:

[0068] Determine whether the bandwidth is less than a preset bandwidth threshold;

[0069] If it is less than, the preset scanning frequency point number is recorded as the target scanning frequency point number;

[0070] If it is greater, the step of determining the target scanning frequency point number of the frequency band to be scanned according to the number of frequency bands, the frequency band width, the first parameter and the second parameter is executed.

[0071] Specifically, for a frequency band with a narrower bandwidth, a preset number of scanning frequencies corresponding to the narrower frequency band can be set. Therefore, when determining the target number of scanning frequencies for the frequency band to be scanned, it is determined whether the bandwidth of the frequency band to be scanned is less than the preset bandwidth threshold. If the bandwidth of the frequency band to be scanned is less than the preset bandwidth threshold, the preset number of scanning frequencies can be recorded as the target number of scanning frequencies. If the bandwidth of the frequency band to be scanned is greater than the preset bandwidth threshold, the above method is used to determine the target number of scanning frequencies for the frequency band to be scanned based on the number of frequency bands, the bandwidth, the first parameter, and the second parameter.

[0072] As a specific embodiment, the frequency scanning method of the embodiment of the present invention is described:

[0073] like Figure 4 As shown, in this embodiment, the preset bandwidth is 6MHz, and the bandwidths of the frequency bands to be scanned are 5MHz, 10MHz, and 20MHz. Among them, the preset number of scanning frequency points is 40. When the bandwidth is greater than 5MHz and less than or equal to 10MHz, the first value corresponding to the two levels of the first parameter is 1.4, and the second value is 5. When the bandwidth is greater than 10MHz and less than or equal to 20MHz, the first value corresponding to the two levels of the first parameter is 3, and the second value is 10. When the bandwidth is greater than 20MHz, the first value corresponding to the two levels of the first parameter is 5, and the second value is 20. According to the frequency band range where the bandwidth of the frequency band to be scanned is located, the first value and the second value corresponding to the frequency band range are recorded as the first target value and the second target value of the first parameter of the frequency band to be scanned.

[0074] It should be noted that the first parameter is a configuration parameter, which is related to the cell bandwidth and has two levels (the specific value is determined by the different frequency band bandwidths). The second parameter is also a configuration parameter, which is related to the number of nearby base stations and has three levels (the values ​​are 3, 6, and 9 respectively). In the scenario of locking the frequency band to search the network, the second parameter needs to take the maximum value, so 9 is recorded as the fourth target value of the second parameter of the frequency band to be scanned. 3 or 6 can be recorded as the third target value of the second parameter according to the needs.

[0075] For example, if the bandwidth of the frequency band to be scanned is 5MHz, which is less than the preset bandwidth (6MHz), then no matter in the case of multi-band network search or locked-band network search, the number of frequency points to be searched (target scanning frequency points) is 40.

[0076] For example: the bandwidth of the frequency band to be scanned is 9MHz, which is greater than the preset bandwidth (6MHz). The bandwidth range of the 9MHz frequency band to be scanned is greater than 5MHz and less than or equal to 10MHz. Then the first target value and the second target value of the first parameter corresponding to the 9MHz frequency band to be scanned are 1.4 and 5 respectively. The third target value and the fourth target value corresponding to the second parameter of the 9MHz frequency band to be scanned are 3 and 9 respectively. The first scanning frequency point number and the second scanning frequency point number are calculated using the preset scanning frequency point formula. The first scanning frequency point number is 10 / 1.4, which is a positive value, and then multiplied by 9 to obtain the value (63). The second scanning frequency point number is 10 / 5, which is a positive value, and then multiplied by 3 to obtain the value (6). Therefore, in the case of locked-band network search, the number of frequency points that need to be searched is 63. In the case of multi-band network search, the number of frequency points that need to be searched should be 6.

[0077] In an embodiment of the present invention, after determining the target number of scanning frequencies for the frequency band to be scanned, the terminal device decodes the Channel State Information Reference Signal (CRS) and measures the power. The physical cell ID is detected from the determined target frequency. Some target frequencies give successful results, but some do not. The terminal device lists a list of all successful attempts. The terminal device decodes the system message for each target frequency from the list of all successful attempts listed. Through this process, the terminal device can list the frequency, physical cell ID and PLMN (public land mobile network). The terminal device finds out which cell is the candidate cell to be actually resident based on the USIM information (Universal Subscriber Identity Module) and the target frequency in the list of all successful attempts listed, and attempts to decode the system information and perform the registration process.

[0078] The frequency scanning method of the embodiment of the present invention can dynamically configure the number of scanning frequencies.

[0079] The frequency scanning method of the embodiment of the present invention can comprehensively evaluate the number of frequencies that need to be searched based on the bandwidths of different frequency bands, the cell bandwidth and the number of nearby base stations in a scenario where the terminal device supports multiple frequency bands.

[0080] The frequency scanning method of the embodiment of the present invention does not seek to quickly scan the frequencies of other bands in a scenario where the terminal device supports band locking, so as to scan as many frequencies in the band as possible, thereby increasing the number of frequencies that need to be scanned.

[0081] The frequency scanning method of the embodiment of the present invention enables the terminal device to take into account both the time and coverage of searching for available frequencies, thereby achieving the purpose of searching for available cells quickly and accurately.

[0082] The frequency scanning device according to the embodiment of the present invention is used in terminal equipment.

[0083] Figure 5 FIG. 1 is a schematic diagram of a frequency scanning device according to an embodiment of the present invention. Figure 5 As shown, the frequency scanning device 100 includes a determination module 10 , a calculation module 20 and a scanning module 30 .

[0084] Among them, the determination module 10 is used to determine the number of frequency bands and the bandwidth of the frequency band to be scanned of the target channel; the calculation module 20 is used to determine the target scanning frequency point number of the frequency band to be scanned according to the number of frequency bands, the bandwidth, the first parameter and the second parameter, wherein the first parameter is determined by the cell bandwidth and the second parameter is determined by the number of base stations within a preset range; the scanning module 30 is used to scan the frequency points of the frequency band to be scanned based on the target scanning frequency point number.

[0085] According to one embodiment of the present invention, the determination module 10 is used to measure the signal strength of the supported channels after the terminal device is tuned to the supported channels before determining the number of frequency bands and the bandwidth of the frequency band to be scanned for the target channel; and record the channel whose signal strength is greater than a preset strength threshold as the target channel.

[0087] In one embodiment of the present invention, the expression of the preset scanning frequency point number formula is: in, Indicates rounding down.

[0088] According to an embodiment of the present invention, the calculation module 20 is used to record the first scanning frequency point number as the target scanning frequency point number if the number of frequency bands is equal to 1; if the number of frequency bands is greater than 1, record the second scanning frequency point number as the target scanning frequency point number.

[0089] According to one embodiment of the present invention, the calculation module 20 is used to determine whether the bandwidth is less than a preset bandwidth threshold before determining the target scanning frequency number of the frequency band to be scanned based on the number of frequency bands, the bandwidth, the first parameter and the second parameter; if less than, the preset scanning frequency number is recorded as the target scanning frequency number; if greater than, the step of determining the target scanning frequency number of the frequency band to be scanned based on the number of frequency bands, the bandwidth, the first parameter and the second parameter is executed.

[0090] In one embodiment of the present invention, the frequency bandwidth is positively correlated with the first target value and the second target value of the first parameter.
