All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Furthermore, the terms "include" and "have," as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.
Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the invention. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
The communication equipment provided by the embodiment of the invention can be a mobile phone, a tablet personal computer, intelligent wearable equipment and the like.
Referring to fig. 1, fig. 1 is a schematic flow chart of an embodiment of a method for allocating a communication frequency band, the method including:
step 11: the first communication module is assigned either a first frequency band or a second frequency band.
Optionally, in this embodiment, the first communication module and the second communication module may be any one of a WIFI communication module, a bluetooth communication module, an infrared communication module, or a mobile data communication module.
Wi-Fi is a technology that allows electronic devices to connect to a Wireless Local Area Network (WLAN), and typically uses the 2.4G UHF (Ultra High Frequency) or 5G SHF (Super High Frequency) ISM (Industrial Scientific Medical) Radio Frequency (RF) bands.
Among them, bluetooth is a wireless technology standard, which can realize short-distance data exchange between fixed equipment, mobile equipment and building personal area network (using UHF radio waves in ism (industrial Scientific medical) band of 2.4-2.485 GHz).
The mobile data communication module can be any one of 2G, 3G, 4G or 5G communication modules.
In addition, the first communication module and the second communication module can be two communication modules with the same communication mode, but the working frequency bands of the two communication modules are different. For example, both communication modules may be bluetooth modules, but the frequency bands in which the two bluetooth modules operate are different or not identical.
It can be understood that, in this embodiment, the first communication module has at least two operable frequency bands, that is, the first communication module can normally operate at least in both the first frequency band and the second frequency band. Specifically, the application scenario of step 11 in this embodiment is generally that when the first communication module operates alone, the first frequency band or the second frequency band may be arbitrarily allocated to the first communication module.
Optionally, in another embodiment, an appropriate operating frequency band may be allocated to the first communication module according to the signal strength or the signal transmission distance of the first frequency band or the second frequency band adopted by the first communication module. For example, the signal strength of surrounding signal access points with a first frequency band and signal access points with a second frequency band can be periodically detected, and one signal access point with stronger signal strength can be selectively accessed.
Optionally, in another embodiment, an appropriate operating frequency band may also be allocated to the first frequency band according to the signal transmission distance between the first frequency band and the second frequency band. For example, the signal transmission requirement of the user is acquired, the signal transmission distance of the signal transmission requirement of the user is judged, and the signal access point with the proper signal transmission distance is selectively accessed.
In addition, when the first frequency band and the second frequency band both meet the requirements, a frequency band with low power consumption can be selected.
Step 12: and detecting whether the second communication module is opened or not.
The opening in step 12 may be understood as the activation and start of operation of the second communication module. It can be understood that if the second communication module is in the sleep state, but it does not use any frequency band and does not perform any data transmission through the second communication module, it can be considered that the second communication module is not turned on.
Therefore, in step 12, whether the second communication module is turned on or not can be detected, whether the second communication module needs to perform data interaction or not can be detected, or whether the second communication module already has data interaction with other devices can be detected.
If the determination result in step 12 is yes, step 13 is executed.
Step 13: and when the working frequency band of the first communication module is the second frequency band, the working frequency band of the first communication module is switched to the first frequency band.
It can be understood that, in this embodiment, the second communication module has only one working frequency band, and the working frequency band is the same as one of the multiple working frequency bands of the first communication module, that is, the second communication module can work normally in the second frequency band, but cannot work normally in the first working frequency band. Specifically, when the second communication module operates alone, only the second frequency band may be allocated to the second communication module.
Therefore, in step 13, when the first communication module and the second communication module operate simultaneously, since the second communication module can only operate normally in the second frequency band, the second frequency band is preferentially allocated to the second communication module. If the first communication module works in the first frequency band before, the first communication module is kept to work in the first frequency band continuously, and if the second communication module works in the second frequency band before, the working frequency band of the first communication module is switched to the first frequency band.
In an alternative embodiment, the signal strength, signal transmission distance or signal stability of the second frequency band is better than that of the first frequency band, so that the second frequency band is allocated to the first communication module when the first communication module operates alone. The first communication module and the second communication module work simultaneously, a second frequency band is allocated to the second communication module, and the working frequency band of the first communication module is switched to the first frequency band.
In addition, since the second communication module is better than the first communication module, optionally, after step 13, the method may further include: when the first communication module and the second communication module work simultaneously, whether the second communication module is closed or not is detected; if yes, the working frequency band of the first communication module is switched from the first frequency band to the second frequency band.
In the specific application scenarios, at least the following application scenarios are included:
1. the first communication module works in a first frequency band, and when the second communication module is started, a second frequency band is allocated to the second communication module;
2. the first communication module works in a second frequency band, and when the second communication module is started, the second frequency band is allocated to the second communication module, and the working frequency band of the first communication module is switched to the first frequency band;
3. the second communication module works in a second frequency band, and when the first communication module is started, a first frequency band is allocated to the first communication module;
4. the method comprises the following steps that a first communication module and a second communication module are started simultaneously, a first frequency band is allocated to the first communication module, and a second frequency band is allocated to the second communication module;
5. when the first communication module and the second communication module work simultaneously, the first communication module works at a first frequency band, the second communication module works at a second frequency band, the second communication module is closed at the moment, and the working frequency band of the first communication module is switched to the second frequency band.
Optionally, in a specific embodiment, the first communication module is a WIFI communication module, the second communication module is a bluetooth communication module, the first frequency band is 5GHz, and the second frequency band is 2.4 GHz. It can be understood that the WiFi communication module has two working frequency bands of 2.4GHz and 5GHz, and the bluetooth communication module has only one working frequency band of 2.4 GHz. In addition, the 2.4GHz band is transmitted over a greater distance than the 5GHz band.
Combine above-mentioned embodiment, use WIFI communication module during operation, in order to guarantee WIFI communication module's signal transmission distance, can be preferentially for its 2.4GHz frequency channel of distribution. In the working process of the WIFI communication module, if the Bluetooth communication module is started, the Bluetooth communication module only supports the 2.4GHz working frequency band, so that the 2.4GHz frequency band is preferentially allocated to the Bluetooth communication module, and the frequency band of the WIFI communication module is temporarily switched to 5 GHz. When the bluetooth communication module is closed, in order to guarantee the signal transmission distance of WIFI communication module, can switch the frequency channel of WIFI communication module to 2.4GHz again.
Different from the prior art, the method for allocating a communication band disclosed in this embodiment includes: allocating a first frequency band or a second frequency band for the first communication module; detecting whether the second communication module is opened or not; and if so, allocating a second frequency band for the second communication module, and switching the working frequency band of the first communication module to the first frequency band when the working frequency band of the first communication module is the second frequency band. Different from the time-sharing multiplexing of two communication modules, the working frequency bands are distributed to different working frequency bands when the two communication modules work simultaneously, so that the working efficiency of each communication module is improved.
Referring to fig. 2, fig. 2 is a schematic flow chart of another embodiment of a method for allocating a communication frequency band, the method including:
step 21: the first communication module is assigned either a first frequency band or a second frequency band.
Step 22: and detecting whether the second communication module is opened or not.
If the result of the detection in step 22 is yes, step 23 and step 24 are executed.
Step 23: a second frequency band is assigned to the second communication module.
Step 24: when the working frequency band of the first communication module is the second frequency band, a plurality of first signal access points of which the working frequency band is the first frequency band are obtained.
It is understood that, during the execution of the above steps, step 23 and step 24 may be started to be executed simultaneously, and after step 24 is completed, step 25 and step 26 are executed.
Step 25: the signal strengths of the plurality of first signal access points are compared.
Step 26: and the first communication module is accessed to the access point with the maximum signal strength in the plurality of first signal access points.
In this embodiment, since the first communication module originally works in the second frequency band, after the second communication module is turned on, the working frequency band of the first communication module needs to be switched to the first frequency band.
In step 24, nearby networks may be periodically searched for a signal access point whose operating frequency band is the first frequency band.
Taking the case that the mobile phone searches for the WIFI access point, the mobile phone periodically searches for nearby WIFI access points meeting the 5GHz requirement, obtains the signal strength of each WIFI access point, and then accesses the first communication module into the WIFI access point with the maximum signal strength.
In addition, in other embodiments, step 24 may specifically be: when the working frequency band of the first communication module is the second frequency band, a plurality of signal access points, the working frequency band of which is the first frequency band and the signal intensity of which is greater than a preset first threshold value, are obtained and used as a plurality of first signal access points.
Continuing to take the example of searching for the WIFI access point by the mobile phone, it can be understood that if the signal strengths of the multiple access points meeting the 5GHz found by the mobile phone are all relatively low, even if the first communication module is accessed to the WIFI access point with the strongest signal, the first communication module cannot perform data interaction well, and user experience is affected. Thus, a first threshold may be set, i.e. the signal strength of the acquired first signal access points should be greater than the first threshold.
In addition, it can be understood that if the signal strength of the multiple WIFI access points searched by the mobile phone is smaller than the first threshold, it is not necessary to switch the working frequency band of the WIFI communication module from 2.4GHz to 5 GHz. Under the condition, the WIFI communication module and the Bluetooth communication module can share the 2.4GHz frequency band and adopt a time division multiplexing mode to carry out.
Referring to fig. 3, fig. 3 is a schematic flow chart of a method for allocating a communication frequency band according to another embodiment of the present invention, where the method includes:
step 31: the first communication module is assigned either a first frequency band or a second frequency band.
Step 32: and detecting whether the second communication module is opened or not.
If the result of the detection in step 32 is yes, step 33 is executed, and if the result of the detection in step 32 is no, step 34 is executed.
Step 33: and when the working frequency band of the first communication module is the second frequency band, the working frequency band of the first communication module is switched to the first frequency band.
Step 34: when the second communication module is not started, a plurality of second signal access points with a second frequency band as a working frequency band are obtained;
step 35: the signal strengths of the plurality of second signal access points are compared.
Step 36: and accessing the first communication module to the access point with the maximum signal strength in the plurality of second signal access points.
In this embodiment, since the second communication module is not turned on, a suitable signal access point can be found from the plurality of signal access points in the second frequency band.
In step 34, nearby networks may be periodically searched for a signal access point with the second frequency band.
Taking a mobile phone searching for a WIFI access point as an example, the mobile phone periodically searches for nearby WIFI access points meeting 2.4GHz, obtains the signal strength of each WIFI access point, and then accesses the first communication module into the WIFI access point with the maximum signal strength.
In addition, in other embodiments, step 34 may specifically be: when the second communication module is not started, a plurality of signal access points with the working frequency band being a second frequency band and the signal intensity being greater than a preset second threshold value are obtained and used as a plurality of second signal access points.
Continuing to use the mobile phone to search for the WIFI access point as an example, it can be understood that if the signal strengths of the multiple access points meeting 2.4GHz found by the mobile phone are all relatively low, even if the first communication module is accessed to the WIFI access point with the strongest signal, the first communication module cannot perform data interaction well, and user experience is affected. Thus, a second threshold may be set, i.e. the signal strength of the acquired plurality of second signal access points should be greater than the second threshold.
In addition, it can be understood that if the signal strength of the multiple WIFI access points found by the mobile phone is smaller than the second threshold, it is not necessary to switch the working frequency band of the WIFI communication module from 5GHz to 2.4 GHz. Under this condition, can make WIFI communication module adopt the 2.4GHz frequency channel to work.
Referring to fig. 4, fig. 4 is a schematic flow chart of a method for allocating communication frequency bands according to another embodiment of the present invention, in this embodiment, the first communication module is a WIFI communication module, the second communication module is a bluetooth communication module, the first frequency band is 5GHz, and the second frequency band is 2.4 GHz. It is understood that the above detailed description of the first communication module, the second communication module, the first frequency band and the second frequency band is only an example, and does not limit the types of the first communication module, the second communication module, the first frequency band and the second frequency band.
The method comprises the following steps:
step 41: and when the WIFI works, the 2.4GHz frequency band or the 5GHz frequency band is allocated to the WIFI communication module.
Step 42: whether the Bluetooth communication module is started or not is detected.
If the result of the detection of step 42 is yes, step 43 is executed, and if the result of the detection of step 42 is no, step 46 is executed.
Step 43: whether the WIFI communication module works in the 2.4GHz working frequency band or not is detected.
When the detection result of step 43 is yes, step 44 is executed. And if the detection result in the step 43 is negative, maintaining the current working state of the WIFI communication module.
Step 44: and detecting whether a first signal access point with signal strength larger than a first threshold exists in the scanned signal access points with the working frequency band of 5 GHz.
When the detection result of step 44 is yes, step 45 is executed. And if the detection result in the step 44 is negative, maintaining the current working state of the WIFI communication module.
Step 45: and the WIFI communication module is accessed to the signal access point with the maximum signal intensity in the first signal access point.
Step 46: whether the WIFI communication module works in a 5GHz working frequency band or not is detected.
When the detection result of step 46 is yes, step 47 is executed. And if the detection result in the step 46 is negative, maintaining the current working state of the WIFI communication module.
