Detailed Description
In order to enable a person skilled in the art to better understand the technical solutions of the present invention, the technical solutions of 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, customer Premise Equipment) can communicate with the base station, access the operator wireless network through a wireless module, such as a 5G module, a 4G module, etc., and then the customer premise equipment uses the operator wireless network for a terminal (such as a mobile phone, a tablet computer, a notebook computer, a television, etc. communication equipment) through wireless WIFI signals.
Referring to fig. 2, an embodiment of the present invention provides a client front-end device 100, which includes a lan transmission unit 200, a mobile network transmission unit 210, and a processor 220.
The local area network transmission unit 200 is configured to obtain 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 the operator network, and send the frequency range used by the operator network to the processor 220;
the processor 220 is configured to obtain, after the client front-end device is turned on or the area where the client front-end device is located is changed, a frequency band supported by the WIFI signal through the lan transmission unit 200 and obtain, through the mobile network transmission unit 210, a frequency range used by the carrier network if the client front-end device accesses the carrier network and transmits the WIFI signal; if the frequency range used by the operator network is within the preset frequency range, determining a larger limit value of the frequency range used by the operator network and the limit value of the frequency range supported by the WIFI signal; and selecting a frequency range used by the WIFI signal from a frequency range which corresponds to a larger limit value and is selectable by a preset WIFI signal, wherein the frequency range which is selectable by the preset 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-2483.5MHz, and the preset WIFI signal may select a frequency range from 2400MHz-2483.5 MHz.
Wherein, the nouns mentioned in the embodiment of the invention are explained:
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, for example 2300 MHz-2320 MHz;2320MHz-2370MHz;2370MHz-2390MHz;2515MHz to 2675MHz;4800MHz-4900MHz; the frequency range used by the operator network may be part of the frequency band described above. For example, the carrier network uses frequencies in the range 2300MHz to 2309MHz.
The frequency band supported by the WIFI signal is determined according to a protocol supported by the client front end device.
Frequency range selectable by WIFI signal: corresponding to the threshold value. Taking 2400MHz-2483.5MHz as the frequency band supported by the WIFI signal as an example, the limit values of the frequency band 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 2400MHz can be selected to be 2400 MHz-2467 MHz. The WIFI signal corresponding to the limit value of 2483.5MHz can be selected to have the frequency range of 2467 MHz-2483.5 MHz. The frequency band of the WIFI signal corresponding to the divided threshold value may be halved in the middle of the supported channels, that is, in combination with fig. 4, the channel corresponding to the frequency band supported by the WIFI signal is 1-14, the preset WIFI signal corresponding to 2400MHz may be the frequency band of channels 1-6, and the preset WIFI signal corresponding to 2483.5MHz may be the frequency band of channels 7-14.
The frequency range used by the WIFI signal is selected to be the frequency range used by the WIFI signal emitted by the WIFI module of the client front-end equipment during working.
The term "larger limit value" is understood to mean, for example:
for example, the frequency range used by the carrier network is 2300MHz to 2303MHz, the frequency band supported by the wifi signal is 2401MHz to 2483.5MHz, and the range of 2300MHz to 2303MHz is 2483.5MHz, which is a larger limit value than the two limits of 2401MHz and 2483.5MHz, that is, the larger limit value is the frequency value that is most separated from the frequency range used by the carrier network.
Referring to fig. 3, an interactive schematic diagram of a network configured for 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 range, determining a larger limit value of the frequency range used by the operator network and the limit value of the frequency range 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 may be plugged into a USIM card.
The 5G module is used for transmitting large-flow service data through the USB network card.
The 5G module is also used for acquiring an international mobile subscriber identity (IMSI, international Mobile Subscriber Identification Number) of a universal subscriber identity module (USIM, universal Subscriber Identity Module) card inserted on the USB serial port, performing an internet dialing operation through the IMSI, accessing an operator network after the internet dialing is successful, and transmitting a frequency range used by the access operator network to the router.
The router includes a LUCI module (Lua configuration interface ), a UBUS module, and a Modem Service module.
The LUCI module provides a WEB interface service, and is specifically configured to display the WEB interface through a website input by a user, and receive basic parameters 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 with 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, the user selects a configuration mode of a frequency range used by the WIFI signal from basic parameter options of the WIFI signal provided on the WEB interface, when "automatic" is selected, it is indicated that the user selects the automatic configuration mode to obtain the frequency range used by the WIFI signal, and when the 5G CPE works, the router can obtain 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 frequency range used by the WIFI signal is acquired by the user in the non-automatic configuration mode, and when the 5G CPE works, 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), modem Service serving modems.
When the 5G module sends the frequency range used by the operator network to the router, the Modem Service module of the router demodulates the frequency range, and then the UBUS module places the frequency range used by the operator network sent by the 5G module into the action to be executed next by the router, namely, determines whether the frequency range used by the operator network is in a preset frequency band.
The routers in the 5G CPE and the 5G module communicate via an AT (Attention) instruction set or QMI (Qualcomm messaging Interface, high traffic interface).
Wherein the AT instruction set is sent from the Terminal equipment (TE, terminal Equipment) or the data Terminal equipment (DTE, data Terminal Equipment) to the Terminal Adapter (TA, terminal Adapter) or the data circuit Terminal equipment (DCE, data Circuit Terminal Equipment).
Wherein in the present invention, the terminal equipment (TE, terminal Equipment) or the data terminal equipment (DTE, data Terminal Equipment) is a router; the Terminal Adapter (TA) or the data circuit Terminal equipment (DCE, data Circuit Terminal Equipment) is a 5G module.
QMI is a functional interface for multiprocessor interprocess communication provided by high-pass for interaction on the application processor (AP, application Processor) and baseband processor (BP, baseband Processor) sides.
In the present invention, the application processor (AP, application Processor) is a router, and the baseband processor (BP, baseband Processor) is a 5G module.
Because the configuration modes of the frequency ranges used by the WIFI signals in the router of the 5G CPE are different, the following two working modes are included.
The first working mode is an automatic configuration mode based on the frequency range used by the WIFI signal, and the second working mode is a non-automatic configuration mode based on the frequency range used by the WIFI signal.
The first working mode is as follows:
after the 5G CPE is started, the router controls the starting information of the 5G module, after the 5G module receives the starting information of the router, the 5G module carries out the dialing of the network, and after the dialing of the network is successful, the frequency range used by the operator network is sent to the router through QMI or AT.
The router acquires a frequency band supported by the WIFI signal, and the router detects that the frequency range used by the carrier network reported by the 5G module is in a preset frequency band, determines a larger limit value of the frequency range used by the carrier network and the limit value of the frequency band supported by the WIFI signal, and selects the frequency range used by the WIFI signal from the frequency ranges which are selectable by the preset WIFI signal and correspond to the larger limit value. Therefore, when the customer premise equipment is accessed to the operator network and transmits the WIFI signal, the frequency band used by the WIFI is selected to be a larger limit value of the frequency band supported by the WIFI compared with the frequency range used by the operator network, namely, the frequency band is selected from a larger part of frequency bands, and as the frequency range used by the WIFI signal and the frequency range used by the operator network are separated by a certain interval, the mutual interference of the two signals can be reduced, and the data loss is reduced.
Wherein, 5G CPE transmits the WIFI signal through the channel. Each channel is capable of propagating signals of a different frequency range. Taking the frequency band supported by the WIFI signal of the customer premise equipment as an example, the frequency band is 2.4 Ghz-2.4835 Ghz. As shown in fig. 4, the supported frequency band is divided into a plurality of frequency ranges, each frequency range corresponds to a channel, and channels 1 to 14, that is, WIFI signals are transmitted through 14 channels, respectively.
The method for acquiring the frequency band supported by the WIFI signal by the router 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 signals. For example, the number of channels is 1-13, and then, as shown in fig. 4, the frequency band supported by the WIFI signal is a frequency range including 1-13 channels.
And selecting a channel which is farthest from a channel corresponding to the frequency range used by the operator network from channels corresponding to a preset frequency range selectable by the WIFI signal and corresponding to a larger limit 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 value of the frequency band supported by the WIFI signal is an upper threshold value, and the lower threshold value, for example, the frequency band supported by the WIFI signal is 2400MHz-2483.5MHz, then 2400MHz is the upper threshold value, 2483.5MHz is the lower threshold value, and a larger threshold value of the frequency range used by the operator network and the threshold value of the frequency band supported by the WIFI signal is determined, that is, whether 2400MHz or 2483.5MHz is determined.
When determining the selectable frequency range of the preset WIFI signal corresponding to the threshold value, in order to be able to conveniently select the channel, the frequency range may correspond to the channel, for example, the selectable frequency range of the preset WIFI signal corresponding to the upper threshold value may be the frequency range of channels 1 to 6, and the selectable frequency range of the preset WIFI signal corresponding to the lower threshold value may be the frequency range of channels 7 to 13.
The frequency range used by the operator network is 2300 MHz-2303 MHz, the frequency band supported by the wifi signal is 2401 MHz-2483.5MHz, the corresponding channel is 1-14, it can be seen that compared with the frequency range used by the operator network, the larger limit value is 2483.5MHz, the corresponding channel is 8-14, then the channel furthest from the channels 8-14 is selected as 14, and the channel furthest from the channels is selected as 14 because the smaller the interference of the frequency range corresponding to the channel furthest from the channel is.
Since all WIFI signals may operate in the selected channel, it is likely that other devices around the client head-end will also operate on the channel selected in the manner described above, which may be susceptible to other devices around.
Therefore, before working with the selected channel, the router monitors the channel used by the WIFI signal transmitted by other surrounding devices and the corresponding signal strength, and determines that the monitored signal strength corresponding to the selected channel is smaller than the preset value. This reduces signal interference for other devices.
If the router determines that the monitored signal strength corresponding to the selected channel is not smaller than the preset value, selecting a second-far channel from channels corresponding to the frequency range used by the operator network in a channel corresponding to the frequency range selectable by the preset WIFI signal corresponding to the larger threshold value, continuously monitoring whether the signal strength corresponding to the selected channel is smaller than the preset value, and if so, selecting the frequency range corresponding to the second-far channel as the frequency range used by the WIFI signal.
And if the router judges that the corresponding signal intensity in the channels corresponding to the frequency ranges which are corresponding to the preset WIFI signals and can be selected and are corresponding to the larger limit value is not smaller than the preset value, selecting the channel with the smallest signal intensity in the channels corresponding to the frequency ranges which are corresponding to the preset WIFI signals and can be selected and are corresponding to the larger limit value, wherein the frequency range corresponding to the channel with the smallest signal intensity is the frequency range used by the WIFI signals.
The second working mode is as follows:
after the 5G CPE is started, the router determines the current access operator network and transmits the WIFI signal, 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 a frequency band selected by a user when the user provides WEB interface service through a LUCI module of the router.
The router determines that the frequency range used by the operator network is in a preset frequency band, and selects a bandwidth smaller than a target bandwidth from bandwidths which can be used by 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 the bandwidth used by the channel corresponding to the frequency range used by the WIFI signal when the channel works.
Because the bandwidth characterizes the value of the data transmission capacity of the signaling, a relatively small bandwidth is selected from the bandwidths, reducing the capacity of WIFI signaling and thus reducing signal interference to the operator network.
If the frequency range used by the carrier network accessed by the 5G module is changed during the mobile process of the 5G CPE, the frequency range used by the WIFI signal needs to be reset in order to avoid interference caused by the fact that the frequency range used by the newly accessed carrier network is adjacent to the frequency band supported by the WIFI signal.
The process of accessing the frequency range used by the new operator network for the 5G module is:
the 5G module searches a plurality of operator networks of a new area, then sends the operator networks to be used to the base station, the base station provides the resources of the network accessed to the new area to be issued to the 5G module, the 5G module accesses the operator networks of the new area according to the resources of the network accessed to the new area, dials the new operator networks, and then accesses the operator networks of the new area after the dialing is successful.
After the 5G module accesses the operator network of the new area, 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 out a larger limit value, and selecting a frequency range used by the WIFI signal from frequency ranges which can be selected by the preset WIFI signal and correspond to the larger limit value. The selected modes are the first working mode and the second working mode.
In the above structures of fig. 2 and fig. 3, the 5G CPE further includes a WIFI module, after determining a frequency range used by the WIFI signal by the router, writing the frequency range used by the WIFI signal into the WIFI configuration file, and after the 5G CPE is started, the WIFI module performs transmission of the WIFI signal according to the selected frequency range used by the WIFI signal.
It should be noted that, for specific data of the frequency range selectable by the preset WIFI signal corresponding to the preset frequency band and the threshold value, the foregoing is only exemplary, and the user may modify the specific data according to the actual situation.
A schematic flow chart of a working method of the client front-end equipment in the embodiment of the invention is shown in fig. 5.

Referring to fig. 7, other devices around the client front-end device 100 provided in this embodiment of the present invention are: device a, device B, and device C each transmit a WIFI signal, and client front-end device 100 listens to the channel used by the WIFI signal transmitted by device a and the corresponding signal strength, e.g., channel 1, the corresponding signal strength a, the channel used by the WIFI signal transmitted by device B and the corresponding signal strength, e.g., channel 2, the corresponding signal strength B, and the channel used by the WIFI signal transmitted by device C and the corresponding signal strength, e.g., channel 3, the corresponding signal strength C, the channel used by the WIFI signal transmitted by device D, and the corresponding signal strength, e.g., channel 4, the corresponding signal strength D, the channel used by the WIFI signal transmitted by device E, and the corresponding signal strength, e.g., channel 4, the corresponding signal strength E, the channel used by the WIFI signal transmitted by device F, and the corresponding signal strength, e.g., channel 6, the corresponding signal strength F.
The client front-end device 100 determines that the selectable frequency range of the preset WIFI signal corresponding to the larger threshold value includes a plurality of frequency ranges of 1-6, and selects the farthest channel as 1, wherein in 1, the monitored corresponding signal strength a is smaller than the preset value, and the farthest channel is adopted as the frequency range used by the WIFI signal.
If the corresponding signal strength a is monitored to be not smaller than the preset value, selecting the channel 2, judging whether the signal strength b corresponding to the channel 2 is smaller than the preset value, and if so, adopting the channel 2 as the frequency range used by the WIFI signal. Otherwise, judging whether the signal intensity c corresponding to the channel 3 is smaller than a preset value, if so, adopting the channel 3 as the frequency range used by the WIFI signal, and judging by analogy. And if the signal intensities are not smaller than the preset value, selecting the channel which is the smallest and corresponds to the signal intensities from a to g as the frequency range used by the WIFI signal.
In the configuration mode non-automatic configuration mode of the frequency range used by the WIFI signal, namely the frequency range used by the WIFI signal selected by a user, and the frequency range used by the operator network is in a preset frequency band, selecting a bandwidth smaller than a target bandwidth from bandwidths available for channels corresponding to the frequency range used by the WIFI signal, and working by using the frequency range used by the WIFI signal and the selected bandwidth; the target bandwidth is the bandwidth used by the channel corresponding to the frequency range used by the WIFI signal when the channel works.
For example, the bandwidth that can be used by the channel corresponding to the frequency range used by the WIFI signal is 20MHz or 40MHz, and since the target bandwidth is a relatively large bandwidth, the target bandwidth is 40MHz, when the frequency range used by the WIFI signal is found to be adjacent to the frequency range used by the carrier network, that is, the frequency range used by the carrier network is within the preset frequency band, the frequency ranges used by the WIFI signal and 20MHz are adopted for operation.
For example, the bandwidth available for the channels corresponding to the frequency range used by the WIFI signal is 40MHz, 80MHz, or 160MHz. Since the target bandwidth is a relatively large bandwidth, the target bandwidth is 160MHz, and when the frequency range used by the WIFI signal and the frequency range used by the operator network are found to be adjacent and relatively close, that is, the frequency range used by the operator network is within a preset frequency band, one of 40MHz or 80MHz and the frequency range used by the WIFI signal are adopted to operate.
In the above embodiment, since the frequency range used by the WIFI signal is automatically configured, when the client front-end device is started each time, the frequency range used by the WIFI signal used last time is loaded, so 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 WIFI signal last time is cleared.
