Please refer to FIG. 2. FIG. 2 is a second structural block diagram of the customer premises equipment provided by the embodiment of the present application. The customer premises equipment 20 may include a communication bus 21 , a processor 22 , a memory 23 , a SIM card interface 24 and a network interface 25 .

Wherein, the SIM card interface 24 and the network interface 25 may be provided on the customer front-end device 20 to realize different network modes of the customer-end device 20 . Therefore, whether the network mode used by the customer premises equipment 20 is a wired network service or a wireless network service can be determined through business logic. The wired network service needs to be connected to the network interface 25 through a network cable, and the wireless network service needs to insert the SIM card into the SIM card interface 24 to obtain the mobile data network.

The network mode of the customer premises equipment 20 includes a first mode and a second mode, the network mode obtained through the SIM card interface 24 may be the first mode, and the network mode obtained through the network interface 25 may be the second mode. The processor 22 can obtain the current network mode of the customer front-end device 20; when the current network mode is the first mode, the control communication bus 21 is enabled to be closed, so that the use state of the communication bus 21 is in the closed state; when the current network mode is In the second mode, the communication bus 21 is controlled to be turned on, so that the use state of the communication bus 21 is in the open state.

Specifically, the type of the current network mode can be determined by acquiring the type of data generated by the customer premises equipment 20 in the current network mode. For example, if the type of data generated by the customer front-end equipment 20 is data generated through a 5G or 4G network, it means that the current network mode is the first mode; the type of data generated by the customer-end equipment 20 is data generated through a broadband network, It means that the current network mode is the second mode.

Therefore, when the current network mode is the first mode, it means that the customer front-end device 20 generates data through the 5G or 4G network. At this time, the network interface 25 is in the unplugged state, and then the communication bus 21 is controlled to be enabled and closed, so that the communication bus 21 is in the state of being pulled out. Closed state; when the current network mode is the second mode, it means that the customer front-end equipment 20 generates data through the broadband network, and the network interface 25 is in the plug-in state at this time, and then the communication bus 21 is controlled to be turned on, so that the communication bus 21 is in the open state .

For example, the preset time may be set to 1 minute, and the total data size generated by the customer front-end device 20 in 1 minute is 1000M, and the total data includes the first data and the second data. Wherein, the first data is 800M and the second data is 200M. Since the first data is larger than the second data, it means that the data 800M generated by the customer premises equipment 20 through the 5G or 4G network is greater than the data 200M generated through the broadband network. It can be understood that the network mode of the data generated by the customer premise equipment 20 is more inclined to the first mode. Therefore, the communication interface 25 can be controlled to be in the unplugged state, and then the communication bus 21 can be controlled to be turned off, so that the communication bus 21 is closed. Similarly, if the first data is smaller than the second data, the network mode of the customer premises equipment 20 may be more inclined to the second mode, so that the communication bus 21 is in an open state.

In some embodiments, if the size of the first data and the second data are equal or differ by a value smaller than a preset threshold, the communication bus 21 may be in an open state, so that the customer premises equipment 20 is in the first mode at the same time and the second mode to work in the network mode. The size of the preset threshold may be set according to different customer front-end devices 20 , which is not specifically limited here.

As can be seen from the above, in this embodiment, the customer front-end equipment includes: a communication bus, a network interface and a processor, the processor is respectively connected to the communication bus and the network interface, and the processor is used for: acquiring the use state of the network interface; The use state of the communication bus is controlled according to the use state of the network interface. By replacing hardware design with software design, the use state of the communication bus can be dynamically controlled, which can reduce the interference generated by the communication bus during the communication process, reduce system power consumption, and improve software performance.

101. Obtain the usage status of the network interface.

In the related art, the communication bus is enabled in the normally open state on the processor side, but due to the characteristics of the communication bus, it will cause communication interference in the communication frequency band of 125MHz, and when the communication bus is in the open state, it will occupy a lot of system resources accordingly. , such as memory resources, interrupt resources, storage resources, etc. In this embodiment, in order to reduce the interference caused by the communication bus, the use state of the communication bus is controlled through the use state of the network interface, and the communication bus is turned off when it is not needed to avoid interference to the communication, and when the communication bus is in the In the closed state, the occupation of system resources will be correspondingly reduced, and the performance of other software in the customer's pre-installed equipment will be improved.

Wherein, the network interface can be used to connect the network to realize the broadband Internet connection of the customer premise equipment. The network interface can be connected to the downlink of the switching chip, and one or more network interfaces can be set at the downlink position of the switching chip. Different branches of the same operator's broadband network.

The use state of the network interface includes a plugged-in state and an unplugged state.

102. Control the use state of the communication bus according to the use state of the network interface.

Because the network interface in the customer front-end equipment is electrically connected to the downstream position of the switching chip, the upstream position of the switching chip is electrically connected to the processor, and the processor is electrically connected to the upstream communication bus, ie, the communication bus. Therefore, the usage state of the communication bus can be further detected by detecting the usage state of the network interface.

Among them, the use state of the communication bus includes an open state and a closed state.

When the use state of the network interface is in the plug-in state, the control communication bus enable is turned on, so that the use state of the communication bus is in the open state; when the use state of the network interface is in the unplugged state, the control communication bus enable is turned off to enable The usage status of the communication bus is off. Among them, the communication bus enable to open or close is a control signal sent by the processor, the control signal includes input and output, the input represents an allow signal, that is, it can be opened; the output represents a rejection signal, that is, it can be closed.

In some embodiments, the acquired usage state of the network interface is obtained based on whether the level values at both ends of the network interface have changed. Among them, the network interface has an initial level value, and the current level value of the network interface is obtained; it is judged whether the current level value is the same as the initial level value; , it is determined that the use state of the network interface is in the plugged state.

It can be seen from the above that in this embodiment, the use state of the network interface is obtained; and the use state of the communication bus is controlled according to the use state of the network interface. By replacing hardware design with software design, the use state of the communication bus can be dynamically controlled, which can reduce the interference generated by the communication bus during the communication process, reduce system power consumption, and improve software performance.

Please refer to FIG. 4 . FIG. 4 is a second schematic flowchart of a communication control method for a customer premise device provided by an embodiment of the present application. Wherein, the customer front-end device may be a CPE device. Specific steps can include:

201. Obtain the current network mode of the CPE device.

Wherein, a SIM card interface and a network interface may be set on the CPE device to implement different network modes of the CPE device. Therefore, it can be judged by business logic whether the network mode used by the CPE device is a wired network service or a wireless network service. Among them, the wired network service needs to be connected to the network interface through a network cable, and the wireless network service needs to insert the SIM card into the SIM card interface to obtain the mobile data network.

Wherein, the network type may include a first mode and a second mode. The type of the current network mode is determined by acquiring the type of data generated by the CPE device in the current network mode. For example, if the type of data generated by the CPE device is data generated through a 5G or 4G network, it means the current network mode is the first mode; if the type of data generated by the CPE device is data generated through a broadband network, it means the current network mode for the second mode.

202. The current network mode is the first mode, and the communication bus is controlled in the first mode.

The network mode obtained through the SIM card interface is the first mode. When the current network mode is the first mode, the communication bus is controlled to be turned off, so that the use state of the communication bus is in the off state.

Specifically, when the current network mode is the first mode, it means that the CPE device generates data through the 5G or 4G network. At this time, the network interface is in the unplugged state, and then the communication bus is controlled to be enabled and closed, so that the communication bus is in the closed state.

203. The current network mode is the second mode, and the communication bus is controlled in the second mode.

The network mode obtained through the network interface is the second mode. When the current network mode is the second mode, the communication bus enable is controlled to be turned on, so that the use state of the communication bus is turned on.

Specifically, when the current network mode is the second mode, it means that the CPE device generates data through the broadband network, and the network interface is in the plug-in state at this time, and then the communication bus is controlled to be enabled and turned on, so that the communication bus is in the open state.

204. The current network mode is the first mode and the second mode, and the communication bus is controlled in the first mode and the second mode.

The CPE device is in the state of working in the first mode and the second mode at the same time, that is, the data generated by the CPE device includes the data generated by the 5G or 4G network and the broadband network at the same time.

Specifically, when the acquired current network mode is that the first mode and the second mode are performed simultaneously, respectively acquire the first data generated by the customer front-end device in the first mode and the data generated in the second mode within a preset time. second data; compare the size of the first data and the second data; when the first data is greater than the second data, then control the communication bus to enable and close, so that the use state of the communication bus is in a closed state; when the first data is smaller than the second data data, control the communication bus enable to open, so that the use state of the communication bus is in the open state.

For example, the preset time may be set to 1 minute, and the total data size generated by the customer front-end device 20 in 1 minute is 1000M, and the total data includes the first data and the second data. Wherein, the first data is 800M and the second data is 200M. Since the first data is larger than the second data, it means that the data 800M generated by the customer premises equipment 20 through the 5G or 4G network is greater than the data 200M generated through the broadband network. It can be understood that the network mode of the data generated by the customer premise equipment 20 is more inclined to the first mode. Therefore, the communication interface 25 can be controlled to be in the unplugged state, and then the communication bus 21 can be controlled to be turned off, so that the communication bus 21 is closed. Similarly, if the first data is smaller than the second data, the network mode of the customer premises equipment 20 may be more inclined to the second mode, so that the communication bus 21 is in an open state.

In some embodiments, if the size of the first data and the second data are equal or differ by a value smaller than a preset threshold, the communication bus 21 may be in an open state, so that the customer premises equipment 20 is in the first mode at the same time and the second mode to work in the network mode. The size of the preset threshold may be set according to different customer front-end devices 20 , which is not specifically limited here.

To sum up, by controlling the use state of the communication bus 21 through different network modes of the CPE device, when the current network mode does not require the communication bus to work, the communication bus can be enabled and disabled to avoid interference to communication.

It can be seen from the above that in this embodiment, by acquiring the current network mode of the CPE device, when the current network mode is the first mode, the current network mode is the second mode, and the current network mode is the first mode and the second mode, different methods are adopted respectively. The control mode dynamically controls the use state of the communication bus, which can reduce the interference generated by the communication bus during the communication process.
