The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.
It should be noted that, in the frequency band switching method provided in the embodiment of the present application, the execution main body may be a frequency band switching device, and the frequency band switching device may be implemented as part or all of a computer device in a software, hardware, or a combination of software and hardware. In the following method embodiments, the execution subject is a computer device, specifically, a communication device, for example.
Referring to fig. 2, a flowchart of a frequency band switching method according to an embodiment of the present application is shown, and as shown in fig. 2, the frequency band switching method according to the embodiment may include the following steps:
step S100, if the frequency band monitoring value of the communication equipment is detected to be changed, the changed frequency band monitoring value is obtained.
In the base station system, the preceding-stage device inputs the radio frequency signal to the communication device of this embodiment, and the communication device performs processing such as a/D conversion, D/a conversion, gain control, etc. on the accessed radio frequency signal, when the frequency band of the accessed radio frequency signal changes, the operating frequency band of the communication device also needs to be changed accordingly to support the currently accessed radio frequency signal.
In this embodiment, when the communication device operates according to the working frequency band corresponding to the current frequency band monitoring value, if the frequency band of the accessed radio frequency signal changes, the frequency band monitoring value changes, and the change of the frequency band monitoring value indicates that the current working frequency band of the communication device changes, and the communication device needs to switch the current working frequency band.
If the communication device detects that the frequency band monitoring value of the communication device changes, the communication device obtains the changed frequency band monitoring value, and the changed frequency band monitoring value can be set by a user according to the frequency band which is currently required to be supported by the communication device.
And S200, determining a target frequency band corresponding to the changed frequency band monitoring value according to the changed frequency band monitoring value.
Each frequency band monitoring value uniquely corresponds to one working frequency band, the communication equipment determines a target frequency band uniquely corresponding to the changed frequency band monitoring value according to the changed frequency band monitoring value, and the target frequency band is the working frequency band of the communication equipment uniquely corresponding to the changed frequency band monitoring value.
In this embodiment, as an implementation manner, an operating frequency band of the communication device may be a standard frequency band or a non-standard frequency band. The standard frequency band refers to a working frequency band which is universal in the field of communication, and the standard frequency bands in different regions are different, such as national standard, American standard, European standard and the like; the non-standard frequency band refers to a special frequency band which is not in the range of the standard frequency band but is required by an operator.
Step S300, switching the current working frequency band of the communication device to the target frequency band.
The communication device switches the current working frequency band of the communication device to a target frequency band, for example, the communication device determines that the target frequency band corresponding to the changed frequency band monitoring value is a standard frequency band 700L (uplink frequency 737MHz, downlink frequency 707MHz), the communication device switches the current working frequency band of the communication device to the standard frequency band 700L, and after the switching is completed, the communication device covers the uplink frequency 737MHz and the downlink frequency 707MHz and works in the standard frequency band 700L; or, the communication device determines that the target frequency band corresponding to the changed frequency band monitoring value is a non-standard frequency band 2000MHz (uplink frequency 2000MHz, downlink frequency 2000MHz), the communication device switches the current working frequency band of the communication device to the non-standard frequency band 2000MHz, and after the switching is completed, the communication device covers the uplink frequency 2000MHz and the downlink frequency 2000MHz and works in the non-standard frequency band 2000 MHz.
In this embodiment, as an implementation manner, the communication device includes a plurality of signal access units, the plurality of signal access units have the same function and are independent from each other, and are all configured to perform processing such as a/D conversion, D/a conversion, gain control, and the like on an accessed radio frequency signal, and each signal access unit is provided with a corresponding frequency band monitoring value. Specifically, for a signal access unit, such as a target signal access unit, if the communication device detects that a frequency band monitoring value of the target signal access unit changes, a changed frequency band monitoring value is obtained, according to the changed frequency band monitoring value, a target frequency band corresponding to the changed frequency band monitoring value is determined, and then the current working frequency band of the target signal access unit is switched to the target frequency band. Therefore, the communication equipment is compatible with various standard frequency bands and/or non-standard frequency bands through the plurality of signal access units, full-band coverage of the communication equipment is achieved, and signal stability and quality of the communication equipment are guaranteed.
In this embodiment, if it is detected that the frequency band monitoring value of the communication device changes, the changed frequency band monitoring value is obtained; determining a target frequency band corresponding to the changed frequency band monitoring value according to the changed frequency band monitoring value; switching the current working frequency band of the communication equipment to a target frequency band; therefore, if the frequency band monitoring value of the communication equipment changes, the target frequency band is determined according to the changed frequency band monitoring value, and the current working frequency band of the communication equipment is switched to the target frequency band, so that the problem that in the traditional technology, when the frequency band of the communication equipment is switched, the frequency band of the communication equipment needs to be restarted to realize the frequency band switching of the communication equipment, and the signal stability and the signal quality of the communication equipment are poor is solved. In this embodiment, the communication device can realize dynamic switching of the working frequency band of the communication device without restarting, and the signal stability and quality of the communication device are improved.
Fig. 3 is a flowchart illustrating a frequency band switching method according to another embodiment. On the basis of the embodiment shown in fig. 2, in this embodiment, if the non-standard frequency band monitoring value of the communication device changes, the step S200 includes a step S210, specifically:
and step S210, determining the changed non-standard frequency band monitoring value as a target frequency band.
In this embodiment, the frequency band monitoring value of the communication device includes a non-standard frequency band monitoring value and a standard frequency band monitoring value. If the communication equipment detects that the non-standard frequency band monitoring value changes, the changed non-standard frequency band monitoring value is obtained, and the changed non-standard frequency band monitoring value is determined as the target frequency band.
Specifically, if the current operating frequency band of the communication device is a non-standard frequency band, for example, the communication device currently operates in a non-standard frequency band 2000MHz (uplink frequency 2000MHz, downlink frequency 2000MHz) corresponding to the non-standard frequency band monitoring value "2000"; if the communication device detects that the non-standard frequency band monitoring value "2000" changes, and the obtained changed non-standard frequency band monitoring value is "2050", the communication device determines "2050" as a target frequency band, and switches the current working frequency band of the communication device to the non-standard frequency band 2050MHz (uplink frequency 2050MHz, downlink frequency 2050MHz) corresponding to the non-standard frequency band monitoring value "2050".
Further, if the current operating frequency band of the communication device is a standard frequency band, for example, the communication device currently operates in a 1800 frequency band (uplink frequency 1842.5MHz, downlink frequency 1747.5MHz) of the standard frequency band corresponding to the standard frequency band monitoring value "6", where the non-standard frequency band monitoring value is 0, that is, the first value; if the communication device detects that the non-standard frequency band monitoring value "0" changes and the obtained changed non-standard frequency band monitoring value is "2000", the communication device determines "2000" as the target frequency band and switches the current working frequency band to the non-standard frequency band 2000MHz (uplink frequency 2000MHz, downlink frequency 2000MHz) corresponding to the non-standard frequency band monitoring value "2000".
Therefore, when the communication equipment works, if the non-standard frequency band monitoring value of the communication equipment is detected to change, the changed non-standard frequency band monitoring value is obtained, the changed non-standard frequency band monitoring value is determined to be a target frequency band, the non-standard frequency band or the standard frequency band in which the communication equipment works currently is switched to the target frequency band, the target frequency band is the non-standard frequency band, dynamic switching of the working frequency band of the communication equipment is achieved, and signal stability and quality of the communication equipment are improved.
Fig. 4 is a flowchart illustrating a frequency band switching method according to another embodiment. On the basis of the embodiment shown in fig. 2, in this embodiment, if the standard frequency band monitoring value of the communication device changes, the step S200 includes a step S220, specifically:
step S220, according to the changed standard frequency band monitoring value, searching a target frequency band corresponding to the changed standard frequency band monitoring value in a preset standard frequency band mapping table.
The standard frequency band mapping table comprises a mapping relation between each standard frequency band monitoring value and each standard frequency band.
In this embodiment, the frequency band monitoring value of the communication device includes a non-standard frequency band monitoring value and a standard frequency band monitoring value. The standard frequency band mapping table is preset with mapping relationships between the standard frequency band monitoring values and the standard frequency bands, for example, the standard frequency band monitoring value "6" corresponds to a 1800 frequency band (uplink frequency 1842.5MHz, downlink frequency 1747.5MHz) of the standard frequency band, the standard frequency band monitoring value "2" corresponds to a 700U frequency band (uplink frequency 751.5MHz, downlink frequency 781.5MHz) of the standard frequency band, and so on.
The communication device detects that the standard frequency band monitoring value of the communication device changes, and obtains the changed standard frequency band monitoring value, for example, the changed standard frequency band monitoring value is "6", the communication device searches the changed standard frequency band monitoring value "6" in a preset standard frequency band mapping table to correspond to the standard frequency band 1800 frequency band (uplink frequency 1842.5MHz, downlink frequency 1747.5MHz), and determines the searched standard frequency band 1800 frequency band (uplink frequency 1842.5MHz, downlink frequency 1747.5MHz) as the target frequency band.
Further, with continuing reference to fig. 4, in the present embodiment, step S300 includes step S310 and step S320, specifically:
step S310, detecting whether the current operating frequency band is a non-standard frequency band.
The communication device detects whether a current operating frequency band of the communication device is a non-standard frequency band, and specifically, the detection is implemented by detecting whether a non-standard frequency band monitoring value of the communication device is a first value, in this embodiment, the first value may be "0", in other embodiments, the first value may also be "false", and the like, which is not limited herein. If the non-standard frequency band monitoring value of the communication equipment is not the first value, the communication equipment works in the non-standard frequency band currently, and if the non-standard frequency band monitoring value of the communication equipment is the first value, the communication equipment works in the standard frequency band currently.
Step S320, if the current operating frequency band is a non-standard frequency band, setting the non-standard frequency band monitoring value of the communication device to a first value, and switching the current operating frequency band of the communication device to a target frequency band corresponding to the changed standard frequency band monitoring value.
If the current operating frequency band of the communication device is a non-standard frequency band, for example, the communication device currently operates in a non-standard frequency band of 2000MHz (uplink frequency of 2000MHz, downlink frequency of 2000MHz), and the non-standard frequency band monitoring value is "2000", that is, the non-standard frequency band monitoring value is not a first value, the communication device sets the non-standard frequency band monitoring value to the first value, and switches the current operating frequency band of the communication device to a target frequency band corresponding to the changed standard frequency band monitoring value, for example, switches the current operating frequency band of the communication device to a standard frequency band of 1800 frequency band (uplink frequency of 1842.5MHz, downlink frequency of 1747.5 MHz).
When the communication equipment works, if the standard frequency band monitoring value of the communication equipment is detected to change, the changed standard frequency band monitoring value is obtained; searching a target frequency band corresponding to the changed standard frequency band monitoring value in the standard frequency band mapping table, wherein the target frequency band is a standard frequency band; and detecting whether the current working frequency band of the communication equipment is a non-standard frequency band, if so, setting the non-standard frequency band monitoring value of the communication equipment to a first value, and switching the current working frequency band of the communication equipment to a target frequency band corresponding to the changed standard frequency band monitoring value. Therefore, the dynamic switching of the working frequency range of the communication equipment is realized, and the signal stability and quality of the communication equipment are improved.
Fig. 5 is a flowchart illustrating a frequency band switching method according to another embodiment. On the basis of the embodiment shown in fig. 4, after step S310, the method for switching a frequency band of this embodiment further includes step S330, specifically:
step S330, if the current working frequency band is the standard frequency band, switching the current working frequency band of the communication device to a target frequency band corresponding to the changed standard frequency band monitoring value.
If the current operating frequency band of the communication device is the standard frequency band, for example, the communication device currently operates in a 1800 frequency band (uplink frequency 1842.5MHz, downlink frequency 1747.5MHz) corresponding to the standard frequency band monitoring value "6", and the non-standard frequency band monitoring value is 0 at this time, which is the first value.
The changed standard frequency band monitoring value obtained by the communication device is, for example, "2", the communication device finds out that the target frequency band corresponding to the changed standard frequency band monitoring value "2" is a standard frequency band 700U frequency band (uplink frequency 751.5MHz, downlink frequency 781.5MHz) in a preset standard frequency band mapping table, and the communication device switches the current working frequency band from the standard frequency band 1800 frequency band to the standard frequency band 700U frequency band, thereby realizing dynamic switching of the communication device from the standard frequency band to the standard frequency band.
Fig. 6 is a flowchart illustrating a frequency band switching method according to another embodiment. On the basis of the embodiment shown in fig. 2, the frequency band switching method of this embodiment further includes step S410, step S420, and step S430, specifically:
step S410, if the communication equipment is detected to be electrified, acquiring a non-standard frequency band monitoring value.
Step S420, detecting whether the non-standard frequency band monitoring value is the first value.
In step S430, if the non-standard frequency band monitoring value is not the first value, the non-standard frequency band monitoring value is set as the working frequency band of the communication device.
In this embodiment, if the communication device detects that the communication device is powered on, the non-standard frequency band monitoring value of the communication device is obtained, and whether the non-standard frequency band monitoring value is the first value is detected. If the non-standard frequency band monitoring value of the communication device is not the first value, for example, the non-standard frequency band monitoring value is "2000", the communication device sets the operating frequency band of the communication device to be 2000MHz (uplink frequency 2000MHz, downlink frequency 2000MHz), that is, sets the non-standard frequency band monitoring value to be the operating frequency band of the communication device, thereby implementing automatic configuration of the operating frequency band when the communication device is powered on.
In this embodiment, the priority of the non-standard frequency band configuration is higher than that of the standard frequency band configuration. Because the number of the nonstandard frequency bands is small in practical implementation, the user can set the monitoring value of the nonstandard frequency bands only when the operator has the requirement of the special frequency band; when detecting that the communication device is powered on, the communication device in this embodiment first obtains the non-standard frequency band monitoring value, detects whether the non-standard frequency band monitoring value is the first value, and if the non-standard frequency band monitoring value is not the first value, directly sets the non-standard frequency band monitoring value as the working frequency band of the communication device, thereby improving the efficiency of frequency band setting.
Fig. 7 is a flowchart illustrating a frequency band switching method according to another embodiment. On the basis of the embodiment shown in fig. 6, step S420 of this embodiment further includes step S440 and step S450, specifically:
step S440, if the non-standard frequency band monitoring value is the first value, acquiring a standard frequency band monitoring value;
step S450, searching a frequency band corresponding to the standard frequency band monitoring value in a preset standard frequency band mapping table, and setting the searched frequency band as the working frequency band of the communication equipment.
In this embodiment, if the non-standard frequency band monitoring value of the communication device is a first value, for example, the non-standard frequency band monitoring value is "0", the communication device obtains the standard frequency band monitoring value; the frequency band corresponding to the standard frequency band monitoring value is searched in a preset standard frequency band mapping table, for example, the standard frequency band monitoring value is "6", the frequency band corresponding to the standard frequency band monitoring value "6" is found in the standard frequency band mapping table by the communication device to be a standard frequency band 1800 frequency band (uplink frequency 1842.5MHz, downlink frequency 1747.5MHz), and the communication device sets the standard frequency band 1800 frequency band (uplink frequency 1842.5MHz, downlink frequency 1747.5MHz) as the working frequency band of the communication device. After the configuration is completed, the communication device covers 1800 frequency bands and works in 1800 frequency bands.
As an implementation manner, the method for switching a frequency band in this embodiment further includes steps a and b:
step a, acquiring a standard frequency range mapping table.
And b, storing the standard frequency band mapping table in a database.
In this embodiment, the standard frequency band mapping table includes a mapping relationship between each standard frequency band monitoring value input by the user and each standard frequency band, so that the communication device can conveniently search the corresponding standard frequency band according to the standard frequency band monitoring value. In the standard frequency band mapping table, the standard frequency band monitoring value and the standard frequency band can be added or deleted according to the actual requirements during implementation, so that the normal work control of the communication equipment is realized, and the stability and the quality of signals are guaranteed.
