[0048] The realization, functional features, and advantages of the object of the present invention will be further described with reference to the embodiments and the accompanying drawings. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0049] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0050] An embodiment of the present invention provides a 5G backhaul device, which is applied to a network topology system and is used to forward and amplify signals sent from or received by network-side devices, so as to expand the signal coverage range. Among them, the 5G backhaul device is a self-backhaul device that uses microwave backhaul signals.

[0051] Specifically referring to Figure 1 , the 5G backhaul device 10 includes: a first application processor 11, a first power line carrier communication circuit 12, a first wireless communication circuit 13, and a first antenna module 14. Among them, both the first wireless communication circuit 13 and the first power line carrier communication circuit 12 are connected to the first application processor 11, and the first antenna module 14 is connected to the first wireless communication circuit 13.

[0052] The first application processor 11 is used for controlling peripheral devices, processing communication data, etc. For example, the first application processor 11 can statistically analyze its own status information, or the first application processor 11 can decode the communication information received by the first wireless communication circuit 13 or the first power line carrier communication circuit 12 and analyze its real-time level, etc.

[0053] The first power line carrier communication circuit 12 is used for transmitting communication data. For example, the first power line carrier communication circuit 12 communicates with other 5G backhaul devices 10 or a central base station through a power line 19. When the communication status of the first wireless communication circuit 13 of the 5G backhaul device 10 is unstable, the first power line carrier communication circuit 12 sends communication information to other 5G backhaul devices 10 or the central base station; or the first power line carrier communication circuit 12 transmits the status information of the first wireless communication circuit 13 of the 5G backhaul device 10 to the central base station or other 5G backhaul devices 10 in real time or at regular intervals for the central base station to detect the status information of the first wireless communication circuit 13 of the 5G backhaul device 10 in real time or at regular intervals. Among them, the first power line carrier communication circuit 12 can also provide power to the base station through the power line 19.

[0054] The first wireless communication circuit 13 and the first antenna module 14 are used for receiving and sending wireless communication data. The first wireless communication circuit 13 is connected to the first antenna module 14 to realize the reception and transmission of signals of peripheral devices. Among them, the first wireless communication circuit 13 can be a millimeter-wave communication circuit, such as a 5G millimeter-wave communication circuit. Based on the fact that wireless communication is carried out by emitting electromagnetic waves, the first wireless communication circuit 13 and the first antenna module 14 can receive communication information from the user side while transmitting data between 5G backhaul devices 10.

[0055] It can be seen that the 5G backhaul device 10 is a 5G backhaul device 10 having transmission channels for at least two types of communication information. The transmission channels for the at least two types of communication information respectively include a wireless link of the first wireless communication circuit 13 and a power line carrier link of the first power line carrier communication circuit 12. The wireless link of the first wireless communication circuit 13 and the power line carrier link of the first power line carrier communication circuit 12 connect the 5G backhaul device 10 to other 5G backhaul devices 10 or a central base station. The specific working process includes: the first application processor 11 of the 5G backhaul device 10 statistically calculates its own status information in real time or at regular intervals. The status information includes position, capacity, channel quality, etc., and encodes these status information using TURBO or LDPC codes to reduce data retransmission; then the first power line carrier communication circuit 12 and the power line 19 are used to transmit the status information to the central base station or transmit it to the central base station through other 5G backhaul devices 10, so that the central base station can monitor the status of the transmission channels for the at least two types of communication information, facilitating the central base station to select one of the transmission methods as the communication routing information of the 5G backhaul device 10 according to the transmission stability of the at least two types of communication information transmission channels it has. When the 5G backhaul device 10 receives communication information from the user terminal, it can communicate according to the transmission channel with good stability, thereby improving the reliability of data transmission of the 5G backhaul device 10.

[0056] Further, in order to enable the first antenna module 14 in the 5G backhaul device 10 to receive communication information from the user terminal while transmitting data between the 5G backhaul devices 10 without interference, the first antenna module 14 includes at least two first antennas. The frequency bands of the at least two first antennas are different. For example, one of the first antennas is a first backhaul antenna 15 for communicating with other 5G backhaul devices 10 or a central base station, and the other first antenna is a first communication antenna 16 for communicating with the user terminal device. The frequency bands of the first backhaul antenna 15 and the first communication antenna 16 are different. The first backhaul antenna 15 can only receive signals of the same frequency band, and the first communication antenna 16 can also only receive signals sent by devices of the same frequency band of the user terminal. In this way, interference is avoided.

[0057] Still further, the 5G backhaul device 10 further includes a first memory 18, and the first memory 18 is connected to the first application processor 11. The first memory 18 is a large-capacity solid-state memory for temporarily storing communication data that cannot be transmitted in time.

[0058] In this embodiment, the 5G backhaul device 10 is connected to the central base station through the first wireless communication circuit 13 (millimeter-wave link) and the first power line carrier communication circuit 12 (power line carrier link). The millimeter-wave link is used for the access of communication users and the transmission of a large amount of user data; the power line carrier link is used to transmit the status of the millimeter-wave link. In the case where the millimeter-wave link is unavailable, it is also used to transmit important small-capacity user data with high real-time requirements. Other large-capacity user data is stored in the solid-state memory and sent out again when the millimeter-wave link is available. Thereby, the data transmission reliability of the 5G backhaul device 10 is improved, and at the same time, the energy consumption of the 5G backhaul device 10 is reduced. That is, when the transmission state of the first wireless communication circuit 13 in the 5G backhaul device 10 is unstable, the first application processor 11 decodes the communication information received by the first wireless communication circuit 13 from the user-side device, divides it into multiple levels according to the importance and real-time nature of the communication information, and uses the power line carrier link to timely transmit the small-capacity user data with high requirements and high real-time levels to the central base station, while storing other large-capacity user data with low importance and real-time levels in the first memory 18. When the millimeter-wave link is available, the other large-capacity user data with low importance and real-time levels is transmitted to the central base station through the millimeter-wave link. In this way, the timely backhaul of important information is not delayed, the data transmission reliability of the 5G backhaul device 10 is improved, and the energy consumption of the 5G backhaul device 10 is reduced by wirelessly transmitting large-capacity data.

[0059] After the above-mentioned 5G backhaul device 10 is applied to the network topology system, the data transmission reliability of the network topology system is also high, such as Figure 2 shown Figure 2 FIG. is a schematic diagram of a network topology system. An embodiment of the present invention provides a network topology system, which includes a central base station 20 and a plurality of 5G backhaul devices 10. The central base station 20 communicates with the 5G backhaul devices 10 through wireless or power line carrier communication, and the 5G backhaul devices 10 communicate with each other through wireless or power line carrier communication. Among them, the 5G backhaul device 10 includes: a first power line carrier communication circuit 12 for transmitting communication data; a first wireless communication circuit 13 and a first antenna module 14, and the first antenna module 14 is connected to the first wireless communication circuit 13 for receiving and sending wireless communication data.

[0060] Specifically, the central base station 20 of the network topology system is a base station of the optical fiber network. When the 5G backhaul device 10 receives the communication information of the user terminal device, it is necessary to backhaul the communication information to the central base station 20. Whether it is millimeter-wave communication or power line carrier communication between the 5G backhaul device 10 and the central base station 20, a mesh routing is adopted. That is, the multiple 5G backhaul devices 10 can directly communicate with the central base station 20, or can indirectly communicate with the central base station 20 through other 5G backhaul devices 10.

[0061] When the network is running, in the case where the power line carrier working condition is good, the status information of the 5G backhaul device 10 is transmitted to the central base station 20 in real time through the power line carrier (in the case where the power carrier working condition is not good, the status information of the 5G backhaul device 10 can also be transmitted wirelessly in real time). The central base station 20 plans the best route according to the status information and updates the route information to each of the 5G backhaul devices 10 in time. In this way, the communication information of the user terminal can always be transmitted according to the best route.

[0062] For example, in the case where the power carrier and the wireless working conditions of each of the 5G backhaul devices 10 are good, each of the 5G backhaul devices 10 sends the communication status information to the central base station 20. The central base station 20 determines the best route for wireless transmission based on the status information and updates the best route for wireless transmission to each of the 5G backhaul devices 10 in time. Each of the 5G backhaul devices 10 then uses the best wireless route to transmit the communication information to the central base station 20. In the case where the working conditions of the electronic carrier and the wireless are both good, the wireless is dedicated to the transmission of the communication information of the user terminal to save wireless resources and at the same time reduce the energy consumption of the 5G backhaul device 10. The status information is transmitted by the power line to ensure that the central base station 20 can receive the status information in time and reliably.

[0063] Another example is that in the case where the wireless working conditions of some or all of the 5G backhaul devices 10 are unstable, each of the 5G backhaul devices 10 sends its own status information to the central base station 20. The central base station 20 determines that part or all of the wireless is unavailable based on the status information, and plans for the 5G backhaul devices 10 with unavailable wireless to use power line carrier communication. The route information containing the power line carrier is updated to each of the 5G backhaul devices 10 in time. Each of the 5G backhaul devices 10 backhauls the communication information according to the route information.

[0064] For another example, in each of the 5G backhaul devices 10, when the power carrier of at least one of the 5G backhaul devices 10 fluctuates, the status information of each of the 5G backhaul devices 10 is wirelessly sent to the central base station 20. In this way, the two systems back up each other, which will greatly improve the reliability of 5G millimeter-wave network communication.

[0065] In this embodiment, the network topology system includes a central base station 20 and a plurality of 5G backhaul devices 10 having wireless and power line carrier communications as described above. When wireless is unavailable, the 5G backhaul device 10 uses the power line carrier to backhaul communication information to ensure that the communication information of the user terminal can be timely transmitted to the central base station 20, improving the stability and reliability of data transmission of the network topology system.

[0066] Based on the fact that the 5G backhaul device 10 has wireless and power line carrier communications, the central base station 20 at least also has the wireless and power line carrier communications. Specifically, refer to Figure 3 , the central base station 20 includes:

[0067] A second power line carrier communication circuit 22, which is used to communicate with the first power line carrier communication circuit 12 of the 5G backhaul device 10;

[0068] A second wireless communication circuit 23 and a second antenna module 24 connected to the second wireless communication circuit 23, and the second antenna module 24 is used to communicate with the first antenna module 14 of the 5G backhaul device 10.

[0069] It can be understood that the second power line carrier communication circuit 22 and the first power line carrier communication circuit 12 of the 5G backhaul device 10 are connected by a power line 19, and the central base station 20 and the 5G backhaul device 10 communicate through the power line 19. The second wireless communication circuit 23 and the first wireless communication circuit 13 of the 5G backhaul device 10 communicate through the second antenna module 24 and the first antenna module 14, so that the central base station 20 and the 5G backhaul device 10 realize wireless communication.

[0070] Among them, the second wireless communication circuit 23 may be a millimeter-wave communication circuit, such as a 5G millimeter-wave communication circuit.

[0071] Furthermore, the central base station 20 can also directly communicate with the devices at the user side. That is, the second antenna module 24 includes at least two second antennas. One of the second antennas has the same frequency band as one of the first antennas of the 5G backhaul device 10. For example, one of the second antennas is the second backhaul antenna 25, and the second backhaul antenna 25 has the same frequency band as the first backhaul antenna 15, and is used to receive the communication information of the first backhaul antenna 15, or to send communication information to the first backhaul antenna 15; the other second antenna has the same frequency band as the other first antenna of the 5G backhaul device 10. For example, the other second antenna is the second communication antenna 26 for communicating with the devices at the user side, and the second communication antenna 26 has the same frequency band as the first communication antenna 16 of the 5G backhaul device 10, and both can receive the signals sent by the co-frequency devices at the user side.

[0072] Furthermore, the central base station 20 further includes a second application processor 21, and the second application processor 21 is connected to the second power line carrier communication circuit 22 and the second wireless communication circuit 23. The second application processor 21 is used for controlling peripheral devices, parsing communication data, status information, and reason information, etc. For example, when the second application processor 21 receives the status information of each 5G backhaul device 10, it parses the status information, generates the best routing information of each 5G backhaul device 10 according to the parsed status information, and then updates the routing information to each 5G backhaul device 10, so that the 5G backhaul device 10 can use the best routing information for communication. In addition, the central base station further includes a second memory 28, and the second memory 28 is connected to the first application processor 21. The second memory 28 is also a large-capacity solid-state memory, and is used for temporarily storing communication data that cannot be transmitted in time.

[0073] Still further, the central base station 20 is a base station with an optical fiber network. Specifically, the central base station 20 further includes an optical fiber communication circuit 27, and the optical fiber communication circuit 27 is connected to the second application processor 21. The optical fiber communication circuit 27 is used to transmit the data received by the central base station 20 to the core network.

[0074] The network topology system provided by the embodiments of the present invention is applied to a 5G millimeter-wave base station. By adding power line carrier communication as an auxiliary on the 5G millimeter-wave base station, the reliability of the network can be greatly improved. The network topology system in the embodiments of the present invention is based on the mutual backup and complementarity between wireless and power line carrier, so that the network topology system meets the three application scenarios of enhanced mobile broadband (eMBB), massive machine-type communication (mMTC), and ultra-reliable and low-latency communication (uRLLC) of 5G.

[0075] Based on the above 5G backhaul device, an embodiment of the communication method of the 5G backhaul device is provided in the invention embodiment. Refer to Figure 4 , the communication method of the 5G backhaul device includes the following steps:

[0076] Step S10, the 5G backhaul device receives communication information and obtains routing information;

[0077] Step S20, determine the target communication channel according to the routing information, where the communication channel includes a wireless communication channel and a power line carrier communication channel;

[0078] Step S30, use the target communication channel to transmit the communication information to other 5G backhaul devices or the central base station.

[0079] The 5G backhaul device is applied to the network topology system, and is used to forward and amplify the signals sent by the network side device or received from the network side device, so as to expand the signal coverage range. Among them, the path for the 5G backhaul device to forward the signal is determined according to its routing information, and the routing information is updated by the central base station in real time or regularly, and then sent to each backhaul device. For example, when the central base station receives the status information transmitted by the 5G backhaul device (the status information includes location, capacity, channel quality, etc.), the routing information of the 5G backhaul device is generated according to the status information of the 5G backhaul device, and then sent to the 5G backhaul device. After receiving the routing information, the 5G backhaul device updates the stored routing information with the newly received routing information.

[0080] Since the 5G backhaul device includes a first power line carrier communication circuit and a first wireless communication circuit, the first circuit carrier communication circuit and the first wireless communication circuit can enable the 5G backhaul device to achieve dual-channel communication, that is, the 5G backhaul device has at least two communication channels, a wireless communication channel and a power line carrier communication channel, so that its routing information can be a wireless communication channel or a power line carrier communication channel. Based on this, when the 5G backhaul device receives communication information, it obtains routing information, determines the target communication channel that can be transmitted according to the routing information, so as to determine which communication channel to use to transmit the communication information, and then uses the target communication channel for communication, where the communication information can be the communication information sent by the user terminal or the communication information transmitted by other 5G backhaul devices.

[0081] It can be understood that the 5G backhaul device sends its own status information to the central base station in real time or at regular intervals. The central base station determines the currently highly stable communication channel based on the status information of the 5G backhaul device, and uses the currently highly stable communication channel as the routing information of the 5G backhaul device. The 5G backhaul device can determine the target communication channel based on the routing information. If the current wireless communication channel is highly stable, the wireless communication channel is used as the routing information of the 5G backhaul device, and the 5G backhaul device determines that the target communication channel is the wireless communication channel based on the routing information.

[0082] In this embodiment, based on the fact that the 5G backhaul device has at least two communication channels, namely a wireless communication channel and a power line carrier communication channel, the 5G backhaul device can always select a communication channel with high transmission stability for communication, improving the reliability of data transmission of the 5G backhaul device.

[0083] Further, referring to Figure 5 , in another embodiment, based on the above embodiment, since at least two communication channels of the 5G backhaul device are a wireless communication channel and a power line carrier communication channel, and the transmission characteristics of the wireless communication channel and the power line carrier communication channel are different. For example, when using the wireless communication channel for transmission, the transmission speed is faster, but it is affected by the environment and the output reliability is poor; when using the power line carrier communication channel for transmission, the transmission stability is guaranteed, but the transmission speed is slow and the energy consumption is high. Therefore, in order to improve the transmission reliability and reduce the energy consumption at the same time, this embodiment adopts different processing methods for communication information according to different target communication channels. For example, when the target communication channel is the power line carrier communication channel, the steps of using the target communication channel to transmit the communication information to other 5G backhaul devices or the central base station include:

[0084] Step S31, obtaining the communication content with high real-time performance in the communication information;

[0085] Step S32, using the power line carrier communication channel to transmit the communication content with high real-time performance to other 5G backhaul devices or the central base station.

[0086] That is, when the wireless communication channel is unstable or unavailable, the central base station uses the power line carrier communication channel as the route of the 5G backhaul device. When the 5G backhaul device needs to use the power line carrier communication channel to transmit communication information, it first transmits the communication content with high real-time performance using the power line carrier communication information to ensure the timely transmission of communication information, and saves the communication content with low real-time performance in the memory of the 5G backhaul device (the first memory in the above 5G backhaul device embodiment). When the routing information of the 5G backhaul device is updated to the wireless communication channel routing information, the communication content with low real-time performance is then transmitted using the wireless communication channel.

[0087] Among them, the communication information received by the 5G backhaul device from the user-end device is divided into multiple levels according to the importance and real-time nature of the communication information. The small-capacity user data with high requirements and high real-time level is determined as the communication content with high implementation level, while the other large-capacity user data with low importance and real-time level is used as the communication content with low real-time level. In this way, the power line carrier communication circuit is used to transmit small-capacity real-time information to ensure the timeliness of information transmission, while the large-capacity information is stored in the memory to reduce the energy consumption of the power line carrier.

[0088] For another example, when the target communication channel is a wireless communication channel, the step of using the target communication channel to transmit the communication information to other 5G backhaul devices or the central base station includes:

[0089] Step S33, when there is communication content with low real-time level stored in the memory, use the wireless communication channel to transmit the communication information and the communication content with low real-time level stored in the memory to other 5G backhaul devices or the central base station. Among them, when using the power line carrier communication channel for communication, the communication content with low real-time level in the communication information is stored in the memory;

[0090] Step S34, when there is no communication content with low real-time level stored in the memory, use the wireless communication channel to transmit the received communication information to other 5G backhaul devices or the central base station.

[0091] If the target communication channel is a wireless communication channel, that is, the current wireless communication channel data transmission of the 5G backhaul device is stable, at this time the 5G backhaul device directly uses the wireless communication channel for information transmission. Among them, the communication information may include the communication information received in real time by the 5G backhaul device from the user end or other 5G backhaul devices, or may include the communication information stored in the memory when the wireless communication channel is unstable (unavailable). That is, after the target communication channel of the 5G backhaul device is a wireless communication channel, if new communication information is received and there is communication content with low real-time level stored in the memory when using the power line carrier communication, the new communication information and the previously stored communication content with low real-time level are sent out in time to prevent information retention; if new communication information is received and there is no communication content stored in the memory, the new communication information is sent out in time.

[0092] It can be understood that in the embodiments of the present invention, the wireless communication channel is preferentially used to transmit communication information, and when the wireless communication channel is unavailable, the power line carrier communication channel is used to transmit information.

[0093] Based on the above network topology system, the present invention further provides a communication method for the network topology system. Referring to Figure 6 , the communication method of the network topology system includes the following steps:

[0094] Step S100, after the 5G backhaul device obtains the status information, it uses the power line carrier communication channel to send the status information to the central base station;

[0095] Step S200, the central base station receives the status information sent by the 5G backhaul device, generates routing information according to the status information, and sends the routing information to the 5G backhaul device.

[0096] The network topology system includes a central base station and multiple 5G backhaul devices. The 5G backhaul devices are directly or connected to the central base station through other 5G backhaul devices. The 5G backhaul devices communicate with the central base station through a wireless communication channel or a power line carrier communication channel.

[0097] In this embodiment, the 5G backhaul device statistically calculates its own status information in real time or at regular intervals, and uses the power line carrier communication channel to send the status information to the central base station. Among them, using the power line carrier communication channel to send the status information enables the status information to be transmitted to the central base station in a timely and stable manner. The central base station generates the routing information of the 5G backhaul device according to the status information of the 5G backhaul device, and sends the routing information to the 5G backhaul device.

[0098] Among them, when it is determined according to the status information that the wireless communication channel of the 5G backhaul device is unstable, the power line carrier communication channel is used as the routing information of the 5G backhaul device. When it is determined according to the status information that the power line carrier communication channel of the 5G backhaul device has a fluctuation, the wireless communication channel is used as the routing information of the 5G backhaul device, or when it is determined according to the status information that the wireless communication channel of the 5G backhaul device returns to stability, the wireless communication channel is used as the routing information of the 5G backhaul device.

[0099] It can be understood that the network topology system has multiple 5G backhaul devices, and the locations of the respective 5G backhaul devices are different. Therefore, it is possible that the wireless communication channels of some of the 5G backhaul devices are unstable, while some of the wireless communication channels are stable. In this case, the central base station determines different routing information according to the information status of different 5G backhaul devices, so as to enable the 5G backhaul device to backhaul communication information with the best path.

[0100] The network topology system in this embodiment can always perform signal transmission in the best communication mode, and the data transmission reliability of the network topology system is high.
