Detailed Description of the Embodiment
[0009] Figure 1FIG. 0 is a block diagram of an embodiment of the transmitting end of the signal conversion system 100 of the present invention. The transmitting end of the signal conversion system 100 includes a processor 10, a transceiver 11, a wireless protocol processor 12, a digital signal processor 13, and a radio frequency module 14. The processor 10 may also be a switch chipset, which can be disposed in an Ethernet device to receive external data signals. The processor 10 includes an Ethernet Media Access Controller (Ethernet MAC Controller) 10a. The Ethernet Media Access Controller 10a may be a functional module or a circuit module supported by the processor 10. The Ethernet Media Access Controller (Ethernet MAC Controller) 10a can be used to transmit and receive Ethernet packets in the Physical Layer mode. The transceiver 11 is connected to the Ethernet Media Access Controller 10a. The wireless protocol processor 12 is coupled to the transceiver 11. The digital signal processor 13 is coupled to the wireless protocol processor 12. The radio frequency module 14 is coupled to the digital signal processor 13. In the transmitting end of the signal conversion system 100, after the processor 10 receives an external data signal, the processor 10 can transmit the external data signal in the form of an Ethernet packet from the Ethernet Media Access Controller 10a to the transceiver 11. After the transceiver 11 receives the Ethernet packet, the wireless protocol processor 12 can use a protocol stack to stack the Ethernet Media Access Control protocol layer corresponding to the Ethernet packet on the wireless communication protocol layer to generate a wireless communication packet. The digital signal processor 13 can generate a wireless communication signal based on the wireless communication packet. The wireless communication signal is then transmitted using the radio frequency module 14. Herein, the external data signal can be generated by a wired Ethernet device, and the wireless communication signal can be a mobile communication signal, such as a fourth-generation mobile communication (4G) signal or a fifth-generation mobile communication (5G) signal, but the present invention is not limited thereto. In the operation mode described above, the transmitting end of the signal conversion system 100 can convert a wired external data signal into a wireless communication signal. Moreover, the transceiver 11, the wireless protocol processor 12, the digital signal processor 13, and the radio frequency module 14 can be integrated into a wireless signal transmitting end module 16. The wireless signal transmitting end module 16 can be externally connected to the processor 10. The wireless signal transmitting end module 16 and the processor 10 can also be disposed on the same module. The transmitting end of the signal conversion system 100 can be a chip architecture or a multi-chip module architecture. It should be understood that the Ethernet packet can be carried by a wired signal. And the processor 10 of the present invention can also receive any form of external data signal, such as a multimedia signal, a network signal, a wired signal, etc. The content and form of the external data signal received by the processor 10 are not limited to the present invention. Any reasonable hardware change or technical modification belongs to the scope disclosed by the present invention.Details of the operation of the transmitting end of the signal conversion system 100 will be described below.
[0010] As mentioned above, the processor 10 includes an Ethernet media access controller 10a. After the processor 10 receives an external data signal, the Ethernet media access controller 10a can connect the external data signal in the form of an Ethernet packet to the physical layer mode of the transceiver end 11 in the media access mode. Therefore, the Ethernet packet can be transmitted to the transceiver 11 through the physical layer interface. It should be understood that the form of the Ethernet packet is a digital signal. And the Ethernet media access controller 10a can directly transmit the Ethernet packet in digital form to the transceiver 11 through the physical layer interface. For example, the physical layer interface can be a Reduced Gigabit Media Independent Interface (RGMII) or a Serial Gigabit Media Independent Interface (SGMII). However, the present case is not limited thereto. Specifically, the Ethernet media access controller 10a can direct the Ethernet packet to the data column address of the transceiver 11. Therefore, the transceiver 11 can receive and transmit the Ethernet packet through a First-In-First-Out (FIFO) mechanism according to the data column address. Then, the wireless protocol processor 12 can convert the Ethernet packet into a wireless communication packet. Herein, the wireless protocol processor 12 can use the technology of the protocol stack to "directly" stack the wireless communication protocol layer (such as 5G NR, New Radio Layer) to convert the Ethernet packet into a wireless communication packet. Then, the wireless communication packet can be received by the digital signal processor 13. The digital signal processor 13 can execute a digital-to-analog program to generate a wireless communication signal according to the wireless communication packet. As mentioned above, the wireless communication signal can be a mobile communication signal. Finally, the wireless communication signal can be transmitted through the radio frequency module 14.
[0011] As described above, the Ethernet media access controller 10a can directly transmit Ethernet packets in digital form to the transceiver 11 through the physical layer interface. In other words, in the transmitting end of the signal conversion system 100, the conversion of Ethernet packets to wireless communication packets only requires one packet transfer. The packet transfer at the transmitting end of the signal conversion system 100 only corresponds to the packet transfer between the Ethernet media access controller 10a and the transceiver 11. Since the conversion of Ethernet packets to wireless communication packets only requires one packet transfer, the transmitting end of the signal conversion system 100 can provide the following advantages. First, since only one packet transfer is required, the transmission latency can be significantly reduced. Second, since in the signal processing process, the wireless protocol processor 12 directly stacks the wireless communication protocol layer, the encoding and decoding procedures of the additional protocol layer (such as the USB Protocol Layer) introduced between the processor 10 and the wireless protocol processor 12 are avoided, so the transmission efficiency can be significantly increased. Third, since only one packet transfer is required, the complexity of the synchronization operation between the wireless communication packet and the Ethernet packet is relatively low.
[0012] In the transmitting end of the signal conversion system 100, as Figure 1 shown, it may further include a wireless control and status monitoring module 15. The wireless control and status monitoring module 15 is connected to the Ethernet media access controller 10a to control the Ethernet media access controller 10a to implement control operations such as connection and disconnection, and can also monitor the wireless network connection status through this to obtain the wireless network connection status, such as access point information, access network name, etc. The Ethernet media access controller 10a can perform a synchronization operation on the Ethernet packet and the wireless communication packet. As mentioned above, since the transmitting end of the signal conversion system 100 can provide low transmission latency, the Ethernet media access controller 10a can control the timing of the Ethernet packet at the transmitting end (i.e., the network media access controller 10a). Even if the Ethernet packet is converted into a wireless communication packet, its timing hardly shifts. Therefore, due to the low transmission latency provided by the transmitting end of the signal conversion system 100, the complexity of synchronizing the Ethernet packet and the wireless communication packet is relatively low. In one embodiment, the wireless protocol processor 12 points the Ethernet packet to the corresponding time stamp within the transceiver time of the wireless communication packet to control the synchronization of the wireless communication packet and the Ethernet packet. However, any technology that uses time stamps, headers, or uses timing signals to synchronize the wireless communication packet and the Ethernet packet belongs to the scope disclosed in the present invention.
[0013] Figure 2 It is a schematic diagram of the protocol stack in the transmitting end of the signal conversion system 100. As Figure 2As shown, in the transmitting end of the signal conversion system 100, the external data signal is denoted as D. The Ethernet media access controller 10a can carry the external data signal D on the Ethernet media access control protocol layer MAC_P and transmit the data in the form of an Ethernet packet to the transceiver 11 through the physical layer interface. After the transceiver 11 transmits the Ethernet packet to the wireless protocol processor 12, the wireless protocol processor 12 can directly stack the wireless radio communication layer WR_P (Wireless Radio Communication Layer) on it. Therefore, the packet containing the external data signal D, the Ethernet media access control protocol layer MAC_P, and the wireless communication protocol layer WR_P is the wireless communication packet. Finally, the wireless communication packet can be transmitted by the radio frequency module 14. It should be understood that the wireless communication protocol layer WR_P can be the protocol layer of the 4th generation mobile communication (5G), the protocol layer of the 5th generation mobile communication (5G), or any reasonable wireless communication protocol layer.
[0014] Figure 3 FIG. is a block diagram of an embodiment of the receiving end of the signal conversion system 100. The architecture of the signal conversion system 100 can also be applied to the receiving end. To avoid confusion, Figure 3 the receiving end of the signal conversion system shown hereinafter is referred to as the receiving end of the signal conversion system 200. In Figure 3 it, the receiving end of the signal conversion system 200 includes an Ethernet media access controller 20a, a transceiver 21, a wireless protocol processor 22, a digital signal processor 23, and a radio frequency module 24 within the processor 20. First, the radio frequency module 24 receives the wireless communication signal. Then, the digital signal processor 23 can receive the wireless communication signal through the radio frequency module 24. The digital signal processor 23 can further generate a wireless communication packet based on the wireless communication signal. For example, the digital signal processor 23 can execute an analog-to-digital program to generate a wireless communication packet based on the wireless communication signal. It should be understood that the wireless communication packet can include the external data signal D, the Ethernet media access control protocol layer MAC_P, and the wireless communication protocol layer WR_P (such as Figure 2As shown, it is generated in the form of a protocol stack). Next, the wireless protocol processor 22 can extract the Ethernet media access control protocol layer MAC_P corresponding to the Ethernet packet from the wireless communication packet. Therefore, the transceiver 21 can carry the external data signal D on the Ethernet media access control protocol layer MAC_P and can also transmit it to the Ethernet media access controller 20a in the form of an Ethernet packet. The Ethernet media access controller 20a can be embedded within the processor 20. In other words, the Ethernet packet can be transmitted from the transceiver 21 to the Ethernet media access controller 20a through the physical layer interface. Finally, after the Ethernet packet is received by the Ethernet media access controller 20a, the Ethernet media access control protocol layer MAC_P will be decoded to obtain the external data signal D. Here, the Ethernet packet is carried by a wired signal, and the wireless communication signal can be a mobile communication signal. Similarly, at the receiving end of the signal conversion system 200, the conversion of the wireless communication packet to the Ethernet packet only undergoes one packet transfer. And the packet transfer corresponds to the packet transfer between the Ethernet media access controller 20a and the transceiver 21. In addition, the Ethernet media access controller 20a can point the Ethernet packet to the data column address of the transceiver 21. The transceiver 21 can transmit the Ethernet packet according to the data column address using the first-in-first-out (FIFO) mechanism. Since the conversion of the wireless communication packet to the Ethernet packet only undergoes one packet transfer, the transmission delay can be greatly reduced.
[0015] Figure 4 It is a block diagram of a signal conversion method executed at the transmitting end of the signal conversion system 100. The signal conversion method may include steps S401 to S404. Any reasonable technical change or hardware modification falls within the scope disclosed by the present invention. Steps S401 to S404 are described as follows: Step S401: Receive an external data signal; Step S402: Transmit the external data signal in the form of an Ethernet packet from the Ethernet media access controller 10a to the transceiver 11; Step S403: After the transceiver 11 receives the Ethernet packet, use the protocol stack to stack the Ethernet media access control protocol layer MAC_P corresponding to the Ethernet packet on the wireless communication protocol layer WR_P to generate a wireless communication packet; Step S404: Generate a wireless communication signal based on the wireless communication packet.
[0016] Steps S401 to S404 have been described in detail above, so their details will not be elaborated further. In the transmitting end of the signal conversion system 100, the processor 10 can execute the Ethernet media access controller 10a to perform the packet transmission function of the transceiver 11 in the physical layer mode through the physical layer interface in the media layer mode. Therefore, the Ethernet packet can be directly received by the transceiver 11 through the physical layer interface. Then, the Ethernet packet can directly stack the wireless communication protocol layer on it using the protocol stack to generate a wireless communication packet. Therefore, the transmitting end of the signal conversion system 100 only needs to perform packet transfer once to convert the Ethernet packet into a wireless communication packet, so it can provide the characteristics of low transmission delay, high transmission efficiency, and easy synchronization.
[0017] Figure 5 It is a block diagram of the signal conversion method executed by the receiving end of the signal conversion system 200. The signal conversion method may include steps S501 to S504. Any reasonable technical change or hardware modification belongs to the scope disclosed by the present invention. Steps S501 to S504 are described as follows: Step S501: Receive a wireless communication signal; Step S502: Generate a wireless communication packet according to the wireless communication signal; Step S503: Extract the Ethernet media access control protocol layer MAC_P corresponding to the Ethernet packet from the wireless communication packet, where the wireless communication packet is generated by stacking the Ethernet media access control protocol layer MAC_P corresponding to the Ethernet packet on the wireless communication protocol layer WR_P; Step S504: Transmit the Ethernet packet from the transceiver 21 to the Ethernet media access controller 20a.
[0018] Steps S501 to S504 have been described in detail above, so their details will not be elaborated further. In the receiving end of the signal conversion system 200, similarly, since the wireless communication packet is generated by stacking the Ethernet media access control protocol layer MAC_P corresponding to the Ethernet packet on the wireless communication protocol layer WR_P, the wireless protocol processor 22 can directly extract the Ethernet media access control protocol layer MAC_P corresponding to the Ethernet packet from the wireless communication packet. In addition, in the receiving end of the signal conversion system 200, only one packet transfer is needed to convert the wireless communication packet into an Ethernet packet, so it can provide the characteristics of low transmission delay, high transmission efficiency, and easy synchronization.
[0019] In summary, the present invention describes a signal conversion method and a signal conversion system. The transmitting end of the signal conversion system has an Ethernet media access controller. The Ethernet media access controller can directly transmit Ethernet packets to a transceiver through a physical layer interface. Moreover, the signal conversion system does not need to introduce an additional communication layer. By simply using a protocol stack to directly stack a wireless communication protocol layer on top of the Ethernet packet, a wireless communication packet can be generated. Therefore, the transmitting end of the signal conversion system only needs one packet transfer to convert an Ethernet packet into a wireless communication packet. In addition, the receiving end of the signal conversion system also has the same advantages as the transmitting end of the signal conversion system. Due to only requiring one packet transfer, the signal conversion system can provide characteristics such as low transmission latency, high transmission efficiency, and low synchronization complexity. The above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made within the scope of the claims of the present invention shall fall within the scope of the present invention.
