Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

Referring to fig. 1, an embodiment of the present invention provides a working scenario diagram of a client front-end device.

The Customer Premise Equipment (wireless CPE) can communicate with a base station, and access to an operator wireless network through a wireless module, for example, a 5G module, a 4G module, etc., and then the Customer Premise Equipment provides the operator wireless network with a wireless WIFI signal for a terminal (for example, a mobile phone, a tablet computer, a notebook computer, a television, etc.) to use.

Referring to fig. 2, an embodiment of the present invention provides a client front-end device 100, which includes a local area network transmission unit 200, a mobile network transmission unit 210, and a processor 220.

The local area network transmission unit 200 is configured to acquire a frequency band supported by the WIFI signal, and send the frequency band supported by the WIFI signal to the processor 220;

a mobile network transmission unit 210, configured to acquire a frequency range used by an operator network, and send the frequency range used by the operator network to the processor 220;

a processor 220, configured to, after the device is turned on or a location area is changed, if the client front-end device accesses an operator network and transmits a WIFI signal, obtain a frequency band supported by the WIFI signal through the local area network transmission unit 200 and obtain a frequency range used by the operator network through the mobile network transmission unit 210; if the frequency range used by the operator network is within the preset frequency band, determining a larger limit value in the frequency range used by the operator network and the limit value of the frequency band supported by the WIFI signal; and selecting a frequency range used by the WIFI signal from a preset selectable frequency range of the WIFI signal corresponding to the larger limit value, wherein the preset selectable frequency range of the WIFI signal is a partial frequency range of a frequency band supported by the WIFI signal.

For example, the frequency band supported by the WIFI signal is 2400MHz to 2483.5MHz, and the selectable frequency range of the preset WIFI signal is a portion of the 2400MHz to 2483.5 MHz.

Wherein, the embodiments of the invention are explained with reference to the nouns:

the preset frequency band is a frequency range used by an operator network with stronger interference with the frequency band supported by the WIFI signal, such as 2300 MHz-2320 MHz; 2320MHz-2370 MHz; 2370MHz-2390 MHz; 2515MHz to 2675 MHz; 4800MHz-4900 MHz; the frequency range used by the operator network may be a part of the frequency band. For example, the frequency range used by the operator network is 2300MHz to 2309 MHz.

The frequency band supported by the WIFI signal is determined according to a protocol supported by the client front-end equipment.

Selectable frequency ranges for WIFI signals: corresponding to the threshold value. Taking the frequency band supported by the WIFI signal as 2400MHz-2483.5MHz as an example, the limit values of the frequency bands supported by the WIFI signal are 2400MHz and 2483.5MHz, respectively, and then the frequency band of the WIFI signal corresponding to the limit value of 2400MHz may be selected as 2400 MHz-2467 MHz. The frequency band of the WIFI signal corresponding to the limit value of 2483.5MHz can be 2467 MHz-2483.5 MHz. The selectable frequency band of the WIFI signal corresponding to the divided limit value is halved in the middle of the supported channel, that is, as shown in fig. 4, the channel corresponding to the frequency band supported by the WIFI signal is 1-14, the selectable frequency band of the preset WIFI signal corresponding to 2400MHz is the frequency band of the channel 1-6, and the selectable frequency band of the preset WIFI signal corresponding to 2483.5MHz is the frequency band of the channel 7-14.

And selecting the frequency range used by the WIFI signal as the frequency range used by the WIFI signal transmitted by the WIFI module of the client front-end equipment when working.

The larger limit values are understood to be, for example:

for example, the frequency range used by the operator network is 2300MHz to 2303MHz, the frequency band supported by the WIFI signal is 2401MHz to 2483.5MHz, and the larger limit value of 2300MHz to 2303MHz is 2483.5MHz, that is, the larger limit value is the frequency value that is the largest apart from the frequency range used by the operator network, compared with the two limit values of 2401MHz and 2483.5 MHz.

Referring to fig. 3, an interactive schematic diagram for configuring a network for a 5G CPE in a 5G scenario is provided in an embodiment of the present invention. The 5G CPE is composed of a router and a 5G module.

The 5G module is used for acquiring a frequency range used by the operator network and sending the frequency range used by the operator network to the router;

the router is used for acquiring a frequency band supported by the WIFI signal and receiving a frequency range used by an operator network; if the frequency range used by the operator network is within the preset frequency band, determining a larger limit value in the frequency range used by the operator network and the limit value of the frequency band supported by the WIFI signal; and selecting a frequency range used by the WIFI signal from a frequency range which is selectable by a preset WIFI signal and corresponds to a larger limit value.

The 5G module comprises a USB serial port and a USB network card.

The USB serial port can be inserted with a USIM card.

The 5G module is used for transmitting large-flow service data through the USB network card.

The 5G Module is further configured to obtain an International Mobile Subscriber Identity (IMSI) of a Universal Subscriber Identity Module (USIM) card inserted in the USB serial port, perform network injection dialing operation through the IMSI, access the operator network after the network injection dialing is successful, and send a frequency range used by the access of the operator network to the router.

The router comprises a LuCI module (Lua configuration interface), a UBUS module and a Modem Service module.

The LUCI module provides a WEB interface service, is specifically configured to display a WEB interface through a website input by a user, and receives a basic parameter of a WIFI signal selected by the user, for example, a frequency range used by the WIFI signal.

Specifically, after the 5G CPE is connected to a device such as a mobile phone, an iPaD, or a computer, a user inputs an IP address of a router on the device such as the mobile phone, the iPaD, or the computer, the router feeds back a WEB interface through the LUCI module, basic parameter options of a WIFI signal provided by the user on the WEB interface select a configuration mode of a frequency range used by the WIFI signal, and when "automatic" is selected, the user selects the automatic configuration mode to acquire the frequency range used by the WIFI signal, so that when the 5G CPE is in operation, the router can acquire the frequency range used by the WIFI signal through the automatic configuration mode. When the user selects a specific frequency range used by the WIFI signal, the fact that the user selects the frequency range used by the WIFI signal acquired in the non-automatic configuration mode is indicated, and then when the 5G CPE is in operation, the router directly reads the frequency range used by the WIFI signal selected by the user.

UBUS is an inter-process communication mechanism in OpenWrt (router platform), and Modem Service serves a Modem.

When the 5G module sends the frequency range used by the operator network to the router, the frequency range used by the operator network is demodulated through a Modem Service module of the router, and then the frequency range used by the operator network sent by the 5G module is put into the action to be executed next by the router through a UBUS module, namely whether the frequency range used by the operator network is in the preset frequency band is determined.

The routers and 5G modules in the 5G CPE communicate via AT (Attention) instruction sets or QMI (Qualcomm messaging Interface).

The AT instruction set is transmitted from a Terminal Equipment (TE) or a Data Terminal Equipment (DTE) to a Terminal Adapter (TA) or a Data Circuit Terminal Equipment (DCE).

In the invention, Terminal Equipment (TE) or Data Terminal Equipment (DTE) is a router; the Terminal Adapter (TA) or the Data Circuit Terminal Equipment (DCE) is a 5G module.

QMI is a functional interface for multiprocessor inter-process communication provided by high-pass, which is used for interaction on the side of an Application Processor (AP) and a Baseband Processor (BP).

In the invention, the Application Processor (AP) is a router, and the Baseband Processor (BP) is a 5G module.

Due to different configuration modes of frequency ranges used by WIFI signals in the router of the 5G CPE, the following two operation modes are included.

The working mode is that the configuration mode based on the frequency range used by the WIFI signal is an automatic configuration mode, and the working mode is that the configuration mode based on the frequency range used by the WIFI signal is a non-automatic configuration mode.

The first working mode is as follows:

after the 5G CPE is started, the router controls the starting information of the 5G module, the 5G module carries out network injection dialing after receiving the starting information of the router, and the frequency range used by the operator network is sent to the router through QMI or AT after the network injection dialing is successful.

The router acquires a frequency band supported by the WIFI signal, and detects that a frequency range used by the operator network reported by the 5G module is within a preset frequency band, a larger limit value of the frequency range used by the operator network and the limit value of the frequency band supported by the WIFI signal is determined, and the frequency range used by the WIFI signal is selected from a preset selectable frequency range of the WIFI signal corresponding to the larger limit value. Therefore, when the customer front-end equipment is accessed to the operator network and transmits WIFI signals, the frequency band used by the WIFI is selected to be a frequency range which is larger than the frequency range used by the operator network and is larger than the limit value of the frequency band supported by the WIFI, namely the frequency range used by the WIFI is selected from a part of frequency bands which are larger in interval.

Wherein, the 5G CPE transmits WIFI signals through the channel. Each channel is capable of propagating signals of a different frequency range. The frequency band supported by the WIFI signal of the client front-end device is 2.4 Ghz-2.4835 Ghz as an example. As shown in fig. 4, the supported frequency band is divided into a plurality of frequency ranges, each frequency range corresponds to a channel, i.e., 1 to 14 channels, i.e., 14 channels are used to transmit WIFI signals.

The mode of the router for acquiring the frequency band supported by the WIFI signal in the automatic configuration mode is as follows: and searching a supported channel list according to the highest protocol configuration supported by the client front-end equipment, wherein the channel list comprises frequency bands supported by the WIFI signal. For example, the number of the channels is 1 to 13, and the frequency band supported by the WIFI signal is a frequency range including 1 to 13 channels as shown in fig. 4.

And selecting a channel which is farthest from a channel corresponding to the frequency range used by the operator network from the channels corresponding to the preset selectable frequency range of the WIFI signal corresponding to the larger threshold value of the router, and taking the frequency range corresponding to the selected channel as the frequency range used by the WIFI signal.

The threshold of the frequency band supported by the WIFI signal is an upper threshold, and the lower threshold, for example, the frequency band supported by the WIFI signal is 2400MHz to 2483.5MHz, then 2400MHz is the upper threshold, and 2483.5MHz is the lower threshold, and the larger threshold of the frequency range used by the operator network and the threshold of the frequency band supported by the WIFI signal is determined, that is, whether 2400MHz or 2483.5MHz is determined.

When the frequency range, which is selectable by the preset WIFI signal and corresponds to the threshold value, is determined, in order to conveniently select the channel, the frequency range may be corresponding to the channel, for example, the frequency range, which is selectable by the preset WIFI signal and corresponds to the upper threshold value, may be a frequency range of channels 1 to 6, and the frequency range, which is selectable by the preset WIFI signal and corresponds to the lower threshold value, may be a frequency range of channels 7 to 13.

The frequency range used by the operator network is 2300 MHz-2303 MHz, the frequency range supported by the WIFI signal is 2401 MHz-2483.5MHz, and the corresponding channel is 1-14, so that compared with the frequency range used by the operator network, the larger limit value is 2483.5MHz, and the corresponding channel is 8-14, the farthest channel is selected from the channels 8-14 to be 14, and as the interference of the frequency range corresponding to the farther and farther channels is smaller, the selected channel is 14 which is the farthest channel.

Since all WIFI signals may be operating on the selected channel, it is likely that other devices around the customer premises equipment also operate on the selected channel, which may be susceptible to the surrounding other devices.

Therefore, before working with the selected channel, the router monitors the channel used by the WIFI signal sent by other surrounding devices and the corresponding signal strength, and determines that the monitored signal strength corresponding to the selected channel is smaller than a preset value. This reduces signal interference from other devices.

If the router determines that the monitored signal intensity corresponding to the selected channel is not less than the preset value, selecting a second far channel from the channels corresponding to the preset frequency range selectable by the WIFI signal and corresponding to the larger threshold value according to the distance sequence of the channels corresponding to the frequency range used by the operator network, continuously monitoring whether the signal intensity corresponding to the selected channel is less than the preset value, and if the signal intensity corresponding to the second far channel is less than the preset value, selecting the frequency range corresponding to the second far channel as the frequency range used by the WIFI signal.

If the router judges that the signal intensity corresponding to the channel corresponding to the selectable frequency range of the preset WIFI signal corresponding to the larger limit value is not smaller than the preset value, the router selects the channel with the minimum signal intensity corresponding to the channel corresponding to the selectable frequency range of the preset WIFI signal corresponding to the larger limit value, and the frequency range corresponding to the channel with the minimum signal intensity is the frequency range used by the WIFI signal.

The second working mode is as follows:

after the 5G CPE is started, the router determines that the current operator network is accessed and the WIFI signal is transmitted, and the configuration mode of the frequency range used by the WIFI signal is a non-automatic configuration mode, namely, the frequency range used by the WIFI signal is the frequency band selected by the user when the user passes through the WEB interface service provided by the LUCI module of the router.

The router determines that a frequency range used by an operator network is within a preset frequency band, selects a bandwidth smaller than a target bandwidth from available bandwidths of channels corresponding to the frequency range used by the WIFI signal, and works by using the frequency range used by the WIFI signal and the selected bandwidth; the target bandwidth is a bandwidth used when a channel corresponding to a frequency range used by the WIFI signal works.

Since the bandwidth represents the value of the data transmission capability of the signal transmission, a relatively small bandwidth is selected from the bandwidths, and the capability of WIFI signal transmission is reduced, thereby reducing signal interference to the operator network.

If the 5G CPE moves, the frequency range used by the operator network to which the 5G module is accessed may change, and thus, in order to avoid interference caused by the fact that the frequency range used by the newly accessed operator network is adjacent to the frequency band supported by the WIFI signal, the frequency range used by the WIFI signal needs to be reset.

The procedure for the 5G module to access the frequency range used by the new operator network is:

the 5G module searches for a plurality of operator networks in a new area, then sends the operator networks determined to be used by the 5G module to the base station, the base station provides resources for accessing the network in the new area and issues the resources to the 5G module, the 5G module accesses the operator networks in the new area according to the resources for accessing the network in the new area and dials the new operator networks, and the operator networks in the new area are accessed after the dialing is successful.

And after the 5G module is accessed to the operator network of a new region, the frequency band used by the new operator is sent to the router through QMI or AT.

The router acquires a frequency band supported by the WIFI signal, determines that a frequency range used by an operator network is within a preset frequency band, and then compares the frequency range used by the operator network with a limit value of the frequency band supported by the WIFI signal; and finding a larger threshold value, and selecting a frequency range used by the WIFI signal from a preset frequency range selectable by the WIFI signal corresponding to the larger threshold value. The selection mode is the first working mode and the second working mode.

In the structures of fig. 2 and fig. 3, the 5G CPE further includes a WIFI module, after the frequency range used by the WIFI signal determined by the router is within the frequency range used by the WIFI signal, the frequency range used by the WIFI signal is written into the WIFI configuration file, and after the 5G CPE is started, the WIFI module transmits the WIFI signal according to the frequency range used by the selected WIFI signal.

It should be noted that, for specific data of a preset frequency range selectable by the WIFI signal corresponding to the preset frequency band and the threshold, the above is only an example, and a user may modify the data according to an actual situation.

Fig. 5 is a schematic flow chart of a working method of a client front-end device according to an embodiment of the present invention.

S500: after the device is started or the located area is changed, if the customer front-end device accesses to the operator network and transmits a WIFI signal, the frequency band supported by the WIFI signal and the frequency range used by the operator network are obtained.

S510: if the frequency range used by the operator network is within the preset frequency band, determining a larger limit value in the frequency range used by the operator network and the limit value of the frequency band supported by the WIFI signal;

s520: and selecting a frequency range used by the WIFI signal from a frequency range which is selectable by a preset WIFI signal and corresponds to a larger limit value.

The preset selectable frequency range of the WIFI signal is a partial frequency range of a frequency band supported by the WIFI signal.

Since the configuration mode of the frequency range used by the WIFI signal may be an automatic configuration mode, that is, the frequency range used by the WIFI signal is selected by the device, or the frequency range used by the WIFI signal selected by the user is not changeable, before the frequency band supported by the WIFI signal is acquired, the configuration mode of the frequency range used by the WIFI signal is determined to be the automatic configuration mode.

The frequency range used by the WIFI signal can be selected by: selecting a channel which is farthest from a channel corresponding to a frequency range used by an operator network from channels corresponding to a frequency range selectable by preset WIFI signals corresponding to a larger limit value, monitoring channels used by the WIFI signals sent by other devices around the customer front-end device and corresponding signal intensity, determining that the monitored signal intensity corresponding to the selected channel is smaller than a preset value, and taking the frequency range corresponding to the selected channel as the frequency range used by the WIFI signals.

As shown in fig. 6, an embodiment of the present invention provides a method for selecting a frequency range used by a WIFI signal, including:

s600: selecting a channel which is farthest compared with a channel corresponding to a frequency range used by an operator network from channels corresponding to a frequency range selectable by a preset WIFI signal corresponding to a larger limit value;

s601: monitoring channels used by WIFI signals sent by other devices around the client front-end device and corresponding signal intensity;

s602: judging whether the monitored signal intensity corresponding to the farthest channel is smaller than a preset value, if so, executing S603, otherwise, executing S604;

s603: taking a frequency range corresponding to the selected channel as a frequency range used by the WIFI signal;

s604: selecting one channel from channels corresponding to a preset frequency range selectable by the WIFI signal corresponding to a larger limit value according to a distance sequence;

s605: judging whether the monitored signal intensity corresponding to the selected channel is smaller than a preset value, if so, executing S603, otherwise, executing S606;

s606: judging whether a channel corresponding to a preset selectable frequency range of the WIFI signal corresponding to a larger threshold value which is not judged exists or not; if yes, executing S604, otherwise, executing S607;

s607: and taking the frequency range corresponding to the channel corresponding to the minimum signal intensity in the selected signal intensity as the frequency range used by the WIFI signal.

As shown in fig. 7, other devices around the client front-end device 100 according to the embodiment of the present invention are: device a, device B, and device C each transmit WIFI signals, and client premises equipment 100 listens to a channel and corresponding signal strength used by a WIFI signal transmitted by device a, such as channel 1, corresponding signal strength a, a channel and corresponding signal strength used by a WIFI signal transmitted by device B, such as channel 2, corresponding signal strength B, and a channel and corresponding signal strength used by a WIFI signal transmitted by device C, such as channel 3, corresponding signal strength C, a channel and corresponding signal strength used by a WIFI signal transmitted by device D, such as channel 4, corresponding signal strength D, a channel and corresponding signal strength used by a WIFI signal transmitted by device E, such as channel 4, corresponding signal strength E, a channel and corresponding signal strength used by a WIFI signal transmitted by device F, such as channel 5, the corresponding signal strength f, the channel used by the WIFI signal sent by the device G, and the corresponding signal strength, e.g. channel 6, and the corresponding signal strength G.

The client front-end device 100 determines that a plurality of selectable frequency ranges of the preset WIFI signal corresponding to the larger limit value are 1-6, selects the farthest channel as 1, and if the monitored corresponding signal strength a is smaller than the preset value in 1, adopts the farthest channel as 1 as the frequency range used by the WIFI signal.

If the monitored corresponding signal intensity a is not smaller than the preset value, selecting the channel 2, judging whether the signal intensity b corresponding to the channel 2 is smaller than the preset value, and if so, adopting the channel 2 as a frequency range used by the WIFI signal. Otherwise, whether the signal intensity c corresponding to the channel 3 is smaller than a preset value or not is judged, if so, the channel 3 is adopted as the frequency range used by the WIFI signal, and the judgment is performed by analogy in sequence. And if the signal intensity is not less than the preset value, selecting the channel corresponding to the minimum signal intensity from the a-g signal intensities as the frequency range used by the WIFI signal.

In a non-automatic configuration mode of a frequency range used by a WIFI signal, namely, the frequency range used by the WIFI signal selected by a user and the frequency range used by an operator network are within a preset frequency band, selecting a bandwidth smaller than a target bandwidth from available bandwidths of channels corresponding to the frequency range used by the WIFI signal, and operating by using the frequency range used by the WIFI signal and the selected bandwidth; the target bandwidth is a bandwidth used when a channel corresponding to the frequency range used by the WIFI signal works.

For example, the usable bandwidth of the channel corresponding to the frequency range used by the WIFI signal is 20MHz or 40MHz, and since the target bandwidths are relatively large bandwidths, the target bandwidth is 40MHz, when it is found that the frequency range used by the WIFI signal is adjacent to the frequency range used by the operator network, that is, the frequency range used by the operator network is within the preset frequency band, the frequency ranges used by the 20MHz and the WIFI signal are adopted for operation.

For example, the bandwidth usable by the channel corresponding to the frequency range used by the WIFI signal is 40MHz, 80MHz, or 160 MHz. Since the target bandwidths are relatively large bandwidths, the target bandwidth is 160MHz, and when it is found that the frequency range used by the WIFI signal is adjacent to the frequency range used by the operator network, that is, the frequency range used by the operator network is within the preset frequency band, one of 40MHz or 80MHz and the frequency range used by the WIFI signal are used for working.

In the above embodiment, since the frequency range used by the WIFI signal is automatically configured, the frequency range used by the last WIFI signal may be loaded in the client front-end device each time the client front-end device is turned on, so that when the frequency range used by the WIFI signal is detected to be in the automatic configuration mode, the router is reset, and the frequency range used by the last WIFI signal is cleared.

In an exemplary embodiment, a storage medium including instructions, such as a memory including instructions, executable by a processor to perform the client device operation method is also provided. Alternatively, the storage medium may be a non-transitory computer readable storage medium, which may be, for example, a ROM, a Random Access Memory (RAM), a CD-ROM, a magnetic tape, a floppy disk, an optical data storage device, and the like.

An embodiment of the present invention further provides a computer program product, which, when running on an electronic device, enables the electronic device to execute a method for implementing any of the client front-end device working methods described in the embodiments of the present invention.
