Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without making any creative effort belong to the protection scope of the present application.
At present, equipment with UWB function dies the use frequency band when being produced and delivered from the factory. If the user goes abroad with the device, it is likely that the function cannot be used, resulting in the UWB function of the device being disabled. Therefore, the frequency band switching scheme is provided, the current working frequency band can be determined based on the historical working frequency band record table of the UWB module and the available UWB frequency band of the area where the UWB module is located, normal use of the UWB module in the current area can be guaranteed, UWB function failure is avoided, the available frequency band of the area where a user frequently arrives can be referred to, the available frequency band of the area where the user frequently arrives is covered by the current working frequency band as far as possible, frequent switching of the working frequency band of the UWB module is avoided, and user experience and product universality are improved.
Referring to fig. 1, an embodiment of the present application discloses a frequency band switching method, including:
s101, if the UWB module needs to switch the working frequency range, the current geographic position of the UWB module is obtained.
The current geographic position of the UWB module may be determined by using a positioning technology such as GPS, a network traffic position used by the UWB module, or other manners. And judging whether the UWB module needs to switch the working frequency band, wherein the working frequency band can be manually selected by a user or automatically detected. If the UWB module needs to switch the working frequency band, it indicates that the working frequency band of the current UWB module cannot be used in the current area, and there are two situations: (1) the user does not use the UWB module in the current area; (2) A user uses the UWB module in the current area, but switches the frequency band to the frequency band which can not be used in the current area after going to another area. The automatic detection can be realized by detecting whether the two conditions exist.
And S102, inquiring each available UWB frequency band corresponding to the region to which the geographic position belongs.
The region may be understood as a country, and different countries have different frequency band limitations, which may be referred to in fig. 2. Referring to fig. 2, the available UWB bands corresponding to different countries are different, and one country may correspond to a plurality of available UWB bands. The circles in fig. 2 correspond to DW1000 channels.
Accordingly, the available UWB band of each country can be recorded correspondingly, thereby forming a record table, and a specific record table can be referred to table 1.
TABLE 1
| State of the country | Optimum frequency band | Available UWB frequency band 2 | … | Available UWB frequency band x |
| A | A1 | A2 | Ax | |
| B | B1 | B2 | Bx |
It can be seen that each country corresponds to a commonly used optimal frequency band, which is specified in the international usage standard, and also corresponds to other available UWB frequency bands.
S103, determining the current working frequency band capable of completely covering at least one available UWB frequency band based on the available UWB frequency band and the historical working frequency band record table of the UWB module.
The historical operating frequency band record table can refer to table 2.
TABLE 2
| Record serial number | State of the country | Frequency band | Comprehensive frequency band |
| 1 | A | A1 | —— |
| 2 | B | B1 | B A1+B1 |
In table 2, when the user uses the UWB module in country a, the frequency band A1 is used; when the user uses the UWB module in the country B, the frequency band B is used A1+B1 Or B1. Wherein, B A1+B1 Covers A1 and B1, so that if the operating frequency of the UWB module is set at frequency band B A1+B1 In addition, when the user uses the UWB module in the country A or B, the working frequency of the UWB module does not need to be adjusted, so that frequent switching of frequency bands can be avoided.
Wherein "completely covering" means: any available UWB band lies between the current operating bands, that is: any available UWB band is a subset of the current operating band. Such as: the relation of the interval [1,2] to the interval [0,3], wherein the interval [0,3] completely covers the interval [1,2]. In determining the current operating frequency band, the international standards for UWB need to be followed.
And S104, controlling the UWB module to work in the current working frequency band.
In one embodiment, controlling the UWB module to operate in the current operating frequency band comprises: and setting the working frequency of the UWB module within the range of the current working frequency band, and restarting the UWB module. The UWB module may be disposed on any mobile device, and thus, when the UWB module is restarted, the corresponding mobile device is restarted. When the mobile device is restarted, corresponding prompt information can be popped up, so that a user can confirm whether the device is restarted or not. After the mobile device is restarted, the UWB module can work in the current working frequency band.
In a specific embodiment, after controlling the UWB module to operate in the current operating frequency band, the method further includes: and recording the current working frequency band and the area to a historical working frequency band recording table. Referring to table 2, the areas are recorded corresponding to the respective frequency bands, and one area may record a plurality of frequency bands corresponding thereto. If the current recorded area is recorded in the historical working frequency band recording table, updating the frequency band record corresponding to the corresponding area; otherwise, a record is newly added in the historical working frequency band record table. Therefore, in a specific embodiment, the recording the current operating frequency band and the area to the historical operating frequency band recording table includes: and if the area is recorded in the historical working frequency band recording table, updating the historical working frequency band corresponding to the current area in the historical working frequency band recording table to be the current working frequency band.
The frequency range covered by the frequency band can be marked in the comprehensive frequency band corresponding to each region, so as to determine which regions the frequency band can be used in. Such as: "B" in Table 2 A1+B1 "means: the frequency band covers two frequency bands of A1 and B1, and can be used in two countries of A and B.
Therefore, when the working frequency band of the UWB module needs to be switched is determined, the current geographical position of the UWB module is determined, then the available UWB frequency band corresponding to the area where the geographical position belongs is inquired, the current working frequency band capable of completely covering at least one available UWB frequency band is determined based on the available UWB frequency band and the historical working frequency band record table of the UWB module, and the UWB module is controlled to work in the current working frequency band, so that the UWB module can work normally in the area where the UWB module is located. The current working frequency band of the UWB module is determined based on the historical working frequency band record table and the available UWB frequency band of the area where the UWB module is located, so that normal use of the UWB module in the current area can be guaranteed, UWB function failure is avoided, the available frequency band of the area where a user frequently arrives can be referred to, the available frequency band of the area where the user frequently arrives is covered by the current working frequency band as far as possible, frequent switching of the working frequency band of the UWB module is avoided, and user experience and product universality are improved.
Based on the above embodiments, it should be noted that, in the case that the current operating band completely covers any available UWB band, the current operating band may also cover the historical operating band, such as "B" in table 2 A1+B1 ”。
In one embodiment, therefore, determining a current operating band that completely covers at least one available UWB band based on the available UWB bands and a historical operating band record of the UWB module comprises: if a target available UWB frequency band capable of completely covering at least one historical working frequency band exists in each available UWB frequency band, determining the target available UWB frequency band as a current working frequency band; at least one historical working frequency band is recorded in the historical working frequency band recording table. This is the first way.
For example: there are 3 available UWB frequency bands corresponding to the area to which the geographic location belongs, which are: [1000,2000], [3000,4000], [5000,6000], and the historical operating band record table records: [5500,6000], then the available UWB band [5000,6000] may be selected as the target available UWB band, i.e.: it is taken as the current working frequency band. Because the [5000,6000] can completely cover the history operation frequency band of [5500,6000] with the UWB frequency band.
Therefore, a frequency band which has the largest coverage range and completely covers one or more historical working frequency bands can be selected from all available UWB frequency bands to serve as the current working frequency band, so that the current working frequency band can cover the available frequency band of the region where the user frequently arrives as far as possible, and the frequent switching of the working frequency bands of the UWB module is avoided.
The historical operating frequency band can be preferentially selected from one or more recently used frequency bands so as to improve the selection efficiency. Of course, the whole historical operating frequency band recording table can be traversed for selection.
If the historical operating frequency band which can be completely covered by a certain available UWB frequency band is not found in the historical operating frequency band record table (that is, no target available UWB frequency band exists in all available UWB frequency bands), that is, if no target available UWB frequency band exists in each available UWB frequency band, determining the optimal available UWB frequency band in each available UWB frequency band as the current operating frequency band, or determining any available UWB frequency band in each available UWB frequency band as the current operating frequency band. At this time, the selected current operating frequency band may be valid only for the current region, and thus the universality needs to be improved. Each region corresponds to a commonly used optimal UWB band, which is specified in international usage standards.
Of course, in the case where there is only one available UWB band, there is no choice to select the current operating band, and therefore in one embodiment, the determination of the current operating band that can completely cover at least one available UWB band is based on the available UWB bands and the historical operating band log of the UWB module, and includes: if there is only one available UWB band, the available UWB band is determined as the current operating band. At this time, the selected current operating frequency band may be valid only for the current region, and thus the universality needs to be improved.
In one embodiment, determining a current operating band that completely covers at least one available UWB band based on the available UWB bands and a historical operating band record of the UWB module comprises: and if the historical working frequency band record table has a target historical working frequency band which can completely cover at least one available UWB frequency band, determining the target historical working frequency band as the current working frequency band. This is the second way.
For example: there are 3 available UWB frequency bands corresponding to the area to which the geographic location belongs, respectively: [1000,2000], [3000,4000], [5000,6000], and the history operating band record table records: [4000,6000], then the historical operating band [4000,6000] can be selected as the target historical operating band, i.e.: it is taken as the current working frequency band. Because the historical operating band of [4000,6000] completely covers the available UWB band of [5000,6000 ].
Because there are two kinds of situations when the UWB module needs to switch the working frequency band: (1) the user has not used the UWB module in the present area; (2) The user uses the UWB module in the current area, but switches the frequency band to the frequency band which can not be used in the current area after going to another area. Therefore, the current operating frequency band can be obtained by directly querying the historical operating frequency band record table.
If a target historical operating band that can completely cover at least one available UWB band is found in the historical operating band record table, there are two cases: (1) The user does not use the UWB module in the current area, but the frequency band used by the user in other areas can exactly completely cover one or more available UWB frequency bands in the current area; (2) The user uses the UWB module in the current area, so the historical working frequency band corresponding to the current area can be directly checked in the historical working frequency band record table.
Therefore, in a specific embodiment, the determining, as the current operating frequency band, a target historical operating frequency band in the historical operating frequency band record table, which can completely cover at least one available UWB frequency band, includes: and inquiring the historical working frequency band corresponding to the region in the historical working frequency band record table, and determining the historical working frequency band as the current working frequency band.
Based on the above determination, the current operating band may be: any available UWB frequency band (selected according to the first mode) corresponding to the current region can also be any historical working frequency band (selected according to the second mode), but the finally selected current working frequency band preferentially covers a wider frequency range, so that the available frequency band of the region where the user frequently arrives is covered as far as possible, and the frequent switching of the working frequency band of the UWB module is avoided.
If the current working frequency band can be selected according to the first mode and the second mode, the current working frequency band can be determined by randomly selecting one mode, or a plurality of current working frequency bands (including at least one target historical working frequency band and at least one target available UWB frequency band) can be determined according to the first mode and the second mode, and then one frequency band with the largest coverage area is selected as the current working frequency band.
In one embodiment, if there are at least two target available UWB bands and/or target historical operating bands, the band with the largest coverage area is selected as the current operating band from the at least two target available UWB bands and/or from the at least two target historical operating bands.
The execution sequence of several ways of determining the current operating frequency band may specifically refer to fig. 3, and of course, the execution sequence illustrated in fig. 3 may also be adjusted according to the actual situation. Fig. 3 specifically includes the following steps:
s301, inquiring whether a current region exists in a historical working frequency band recording table; if yes, executing S302; otherwise, executing S303;
s302, determining the historical working frequency band of the current area recorded in the historical working frequency band recording table as the current working frequency band;
s303, judging whether a target available UWB frequency band capable of completely covering some historical working frequency bands exists or not; if yes, go to S304; otherwise, S305 is executed;
s304, selecting a target available UWB frequency band as a current working frequency band;
s305, selecting the optimal available UWB frequency band as the current working frequency band or randomly selecting one available UWB frequency band as the current working frequency band.
Here, S301 and S302 may be deleted, and S303, S304, and S305 may be directly executed. After performing S303, S304 and S305, the determined current operating frequency band is recorded to the historical operating frequency band recording table for use the next time S303 is performed. In S303, the "certain historical operating bands" preferentially select one or more of the historical operating bands that are used most recently.
The frequency band switching scheme provided by the present application is introduced below with reference to a specific scenario, and first, the available UWB frequency bands are recorded, as shown in table 1, and an available UWB frequency band corresponding to each country code is recorded by using one table. The country code is specified by the UWB international standard. Each country corresponds to an international code.
When the frequency band needs to be switched, equipment is firstly positioned, and the current country is confirmed. If the UWB module is arranged in the mobile equipment using the android system, the positioning function can be realized based on a special API provided by the android system, and thus a country code can be positioned. All available UWB bands can be obtained by looking up table 1.
Then, selecting the current working frequency band:
1. if there is only one available UWB band, that band is selected and no history is made. Since the frequency band may be valid only for the current area and cannot cover other areas, it does not contribute to enlarging the coverage area and thus may not be recorded.
2. If there are multiple available UWB bands, the selection may be based on a country code query history. And starting to search from the latest record in the history record, and if the comprehensive frequency band corresponding to the related country code can be searched, selecting the comprehensive frequency band to directly set. And if the comprehensive frequency band corresponding to the country code of the related country code is not searched, screening the frequency band containing the latest N records according to the history record, and selecting the current working frequency band.
For example: when the user arrives at country B, if it is detected that only one frequency band B1 can be used in country B, B1 is set and recording is not performed. If it is detected that a plurality of frequency bands such as B1 … Bx and the like can be used in the country B, the table 2 is inquired, and the frequency band Bn (namely B1 including A, B) is screened from the B1 … Bx by combining the latest N records (assuming that only one record in the country A exists in the current table 2) (namely, the frequency band Bn in the country B is screened from the B1 … Bx A1+B1 ) And setting is carried out, and history records are added after the setting is finished. It can be seen that B A1+B1 Not only covers A, B, but also is the corresponding available UWB frequency band of B country. If the user returns from country B to country a, the UWB functionality of the mobile device will not fail.
When a user first arrives at country C and a plurality of available UWB frequency bands can be selected in country C, the available UWB frequency bands including three countries A, B, C are preferentially selected and set according to the history. If there is no available UWB band encompassing the three countries A, B, C, then the most recently arrived country is selected for coverage. If the user is from A to C, the available UWB band is selected to encompass A, C. If the user is from B to C, the available UWB band is selected to encompass B, C. If the two countries cannot be covered, the optimal frequency band is selected from a plurality of available UWB frequency bands of C country, or randomly selected.
After the frequency band switching is completed, the restarting equipment can take effect. The user may be prompted to manually restart the device here. Therefore, the selection of the available UWB frequency band covering more countries can reduce the equipment restarting frequency, avoid frequent switching of the frequency band, and avoid function failure caused by no switching. The scheme can automatically switch the UWB frequency band, can ensure that the UWB function of the mobile equipment can normally operate under the condition that the user is out of country, and cannot fail.
In the following, a frequency band switching device provided in an embodiment of the present application is introduced, and a frequency band switching device described below and a frequency band switching method described above may refer to each other.
