[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of the People's Republic of China on August 28, 2023, with application number 202311099451.0 and invention name "A communication device, microwave communication equipment and system", the entire contents of which are incorporated by reference into this application. Technical Field

[0003] The present application relates to the field of microwave communication technology, and in particular to a communication device, microwave communication equipment and system. Background Art

[0004] Microwave communication uses microwaves as a medium, eliminating the need for solid media. Microwave transmission is possible when there are no obstacles in the straight-line distance between two points. Microwave communication offers high capacity, high quality, and long-distance transmission. Therefore, microwave communication is a key method of communication and is widely applicable to various specialized communication networks.

[0005] Currently, microwave communication systems may include indoor units (IDUs) and outdoor units (ODUs). The IDU may include a main control board and at least one intermediate frequency (IF) board. The main control board may include multiple service ports for receiving and / or transmitting baseband signals (or service signals), while the IF board may include multiple intermediate frequency (IF) ports for receiving and / or transmitting IF signals.

[0006] However, since the main control board aggregates all services, once the main control board is damaged, the services connected to the entire microwave communication system will not be transmitted normally.

[0007] Summary of the Invention

[0008] The embodiments of the present application provide a communication device, microwave communication equipment, and system for implementing active / standby protection and improving the reliability of product applications.

[0009] In a first aspect, an embodiment of the present application provides a communication device, which may be an IDU, or may be a device including IDU functions, such as a device integrated with an IDU. The communication device may include a first circuit board and a second circuit board; the first circuit board includes N1 service ports, M1 intermediate frequency ports, a first processing unit, and a first switching unit; the second circuit board includes N2 service ports, M2 intermediate frequency ports, a second processing unit, and a second switching unit; the M1 intermediate frequency port or the M2 intermediate frequency port is used to connect to a second communication device; the first circuit board is a main circuit board, and the second circuit board is a backup circuit board; or the second circuit board is the main circuit board, and the first circuit board is a backup circuit board.

[0010] In this way, since the first and second circuit boards can serve as active and standby circuit boards for each other, active and standby protection can be achieved, improving the reliability of product applications. In addition, since the first circuit board can integrate service ports and intermediate frequency ports, and the second circuit board can integrate service ports and intermediate frequency ports, that is, the first and second circuit boards are both integrated boards, which can effectively improve the integration level.

[0011] In one possible design, the first circuit board and the second circuit board are connected via a P root bus, which includes a P1 root bus and a P2 root bus. The P1 root bus is used for the first circuit board to send business data to the second circuit board, and the P2 root bus is used for the second circuit board to send business data to the first circuit board; wherein P is less than 2*(M1+N1+M2+N2).

[0012] In this way, the first circuit board can send service data to the second circuit board via bus P1. That is, service data from different service ports and IF ports on the first circuit board can be sent to the second circuit board (e.g., to the switching unit of the second circuit board) via bus P1, and different service ports and IF ports on the second circuit board can receive service data from the first circuit board (e.g., receive service data from the switching unit of the first circuit board) via bus P1. For example, if P1 = 1, service data from different service ports and IF ports on the first circuit board are sent to the second circuit board via the same bus, and service data from different service ports and IF ports on the second circuit board are received from the first circuit board via the same bus. Therefore, compared to the method of "service data from different service ports and IF ports on the first circuit board are sent to the second circuit board via different buses," P1 can be less than M1+N1+M2+N2. Similarly, P2 can also be less than M1+N1+M2+N2, that is, P can be less than 2*(M1+N1+M2+N2), thereby effectively reducing the number of wiring and wiring space.

[0013] In one possible design, the P-root bus is a serial bus.

[0014] In one possible design, the transmission bandwidth of the P1 root bus is greater than or equal to the sum of the transmission bandwidths corresponding to the N1 service ports and the M1 intermediate frequency ports; and / or, the transmission bandwidth of the P2 root bus is greater than or equal to the sum of the transmission bandwidths corresponding to the N2 service ports and the M2 intermediate frequency ports.

[0015] For example, the maximum transmission bandwidth required for the first circuit board to send data to the second circuit board is the sum of the uplink transmission bandwidth corresponding to the N1 service port and the M1 intermediate frequency port, and the downlink transmission bandwidth corresponding to the N2 service port and the M2 intermediate frequency port. However, in actual scenarios, it may rarely occur that while the N1 service port and the M1 intermediate frequency port are performing uplink transmission, the N2 service port and the M2 intermediate frequency port are also performing downlink transmission. Therefore, by comprehensively considering the actual scenarios and resource consumption, the transmission bandwidth of the P1 root bus can be set to be greater than or equal to the sum of the transmission bandwidths corresponding to the N1 service port and the M1 intermediate frequency port; similarly, the transmission bandwidth of the P2 root bus can also be set to be greater than or equal to the sum of the transmission bandwidths corresponding to the N2 service ports and the M2 intermediate frequency ports.

[0016] In one possible design, the second circuit board includes a transfer unit; the transfer unit is used to: receive first business data, and if it is determined that the first circuit board is the main circuit board and the second circuit board is the backup circuit board, send the first business data to the first circuit board through the P2 root bus; wherein, the first business data includes business data from the N2 business ports, and / or business data from the M2 intermediate frequency ports.

[0017] In this way, by providing a transfer unit, the service data of multiple service ports and / or the service data of multiple intermediate frequency ports can be uniformly sent to the main circuit board through the P2 root bus.

[0018] In one possible design, the first switching unit is used to: receive the first business data; if it is determined that the routing port of the first business data is a port on the second circuit board, send the first business data to the second circuit board through the P1 root bus.

[0019] In one possible design, the second circuit board also includes a first aggregation unit and / or a second aggregation unit; the first aggregation unit is used to: aggregate the service data from the N2 service ports and send it to the transit unit; the second aggregation unit is used to: aggregate the service data from the M2 intermediate frequency ports and send it to the transit unit.

[0020] In one possible design, the first circuit board and the second circuit board are further connected via K buses, and the K buses are used for communication between the first processing unit and the second processing unit.

[0021] In this way, by setting up K buses, the first processing unit and the second processing unit can communicate directly. For example, the first processing unit can send a management command to the second processing unit to manage the intermediate frequency port on the second circuit board, thereby saving the number of wirings and wiring space.

[0022] In one possible design, the K buses are serial buses.

[0023] In one possible design, when the first circuit board is the main circuit board and the second circuit board is the backup circuit board, the K buses are used by the first processing unit to send management commands to the second processing unit; the management commands are used to indicate the first type parameters and / or second type parameters of the M2 intermediate frequency ports; wherein the first type parameters of the M2 intermediate frequency ports include at least one of the following: the modulation mode corresponding to the M2 intermediate frequency ports, the modulation bandwidth corresponding to the M2 intermediate frequency ports, and the transmission power of the M2 intermediate frequency ports; the second type parameters of the M2 intermediate frequency ports include the working status of the M2 intermediate frequency ports.

[0024] In this way, the management command sent by the first processing unit to the second processing unit may include multiple possible parameters, thereby making the implementation more flexible.

[0025] In one possible design, the first circuit board and the second circuit board are further connected via W buses, the W buses including a W1 bus and a W2 bus; the W1 bus is used by the first processing unit to manage the M2 intermediate frequency ports, and the W2 bus is used by the second processing unit to manage the M1 intermediate frequency ports.

[0026] In one possible design, the W buses are parallel buses.

[0027] In a second aspect, an embodiment of the present application provides a microwave communication device, which includes a communication device as described in any possible design of the first aspect above.

[0028] In a third aspect, an embodiment of the present application provides a microwave communication system, comprising a first communication device and a second communication device, wherein the first communication device is the communication device described in any possible design of the first aspect above; the second communication device is used to: receive a first intermediate frequency signal from an intermediate frequency port of the first communication device, convert the first intermediate frequency signal into a first microwave signal and send it; or, receive a second microwave signal, convert the second microwave signal into a second intermediate frequency signal and send it to the first communication device.

[0044] First, some of the terms used in the embodiments of the present application are explained to facilitate understanding by those skilled in the art.

[0045] (1)Microwave communication

[0046] Microwave communication refers to the use of microwaves. Microwaves are electromagnetic waves with a frequency range of 300 megahertz (MHz) to 3 terahertz (THz), where 1 THz = 1000 gigahertz (GHz). Microwaves have a wavelength range of 1 meter to 0.1 millimeter (speed of light = wavelength × frequency). In other words, microwaves have high frequencies and short wavelengths.

[0047] (2) Double send and receive

[0048] In microwave communication systems, a 1+1 hot standby (HSB) configuration is often used to improve communication reliability. This means that two sets of equipment operate at the same frequency, and only one set is operational. If that set fails, the other set takes over, ensuring communication reliability.

[0049] In a hot standby system, the sending side can copy one signal to two output channels (i.e., dual transmission), and the receiving side can select one of the two channels to receive (i.e., selective reception).

[0050] (3) Serial bus and parallel bus

[0051] A bus can be understood as a set of common information transmission lines that can be shared by multiple components in a time-sharing manner. Sharing means that multiple components can be connected to the bus, and the information exchanged between these components can be shared in a time-sharing manner through this set of lines. Time-sharing means that only one component is allowed to send information to the bus at any one time. If there are multiple components in the system, they can only send information to the bus in a time-sharing manner.

[0052] Depending on the transmission format, buses can be categorized as serial buses and parallel buses. As shown in Figure 1A , devices A and B transmit information via a serial bus. A serial bus transmits information serially (i.e., data is transmitted bit by bit), so a serial bus only requires a single signal line. As shown in Figure 1B , devices C and D transmit information via a parallel bus. A parallel bus transmits information in parallel (i.e., it can transmit multiple bits of data simultaneously), so multiple signal lines are required.

[0053] (4) Uplink and downlink transmission

[0054] In the embodiment of the present application, the transmission of service data from the switching chip to the outside can be defined as downlink transmission, and the transmission of service data from the outside to the switching chip can be defined as uplink transmission.

[0055] Figure 2 is a schematic diagram of a microwave communication system provided in an embodiment of the present application. As shown in Figure 2, the microwave communication system may include a first communication device, one or more second communication devices connected to the first communication device, and multiple antenna systems connected to the second communication devices (Figure 2 uses the example of a first communication device connected to two second communication devices, namely second communication device 1 and second communication device 2).

[0056] The first communication device and the second communication device are connected via an intermediate frequency (IF) cable, and the second communication device and the antenna system are connected via a radio frequency cable. For example, the first communication device may be an IDU, or a device including IDU functionality, such as a device integrated with an IDU; the second communication device may be an ODU, or a device including ODU functionality, such as a device integrated with an ODU.

[0057] In the first transmission direction, the first communication device modulates the baseband signal (or service signal) from the transmission device, converts the baseband signal into an intermediate frequency signal, and transmits it to the second communication device via an intermediate frequency cable. The transmission device can be, for example, a router. The second communication device converts the intermediate frequency signal into a microwave signal, amplifies it, and transmits it via the antenna system.

[0058] In the second transmission direction, the antenna system transmits the received microwave signal to the second communication device. The second communication device converts the microwave signal into an intermediate frequency signal and transmits the intermediate frequency signal to the first communication device via the intermediate frequency cable. The first communication device demodulates the intermediate frequency signal, converts it into a baseband signal, and transmits it to the transmission device.

[0059] In the microwave communication system shown in Figure 2, the first communication device may include a main control board and at least one intermediate frequency board. As shown in Figure 3, the first communication device may include a main control board and two intermediate frequency boards (intermediate frequency board 1 and intermediate frequency board 2).

[0060] The main control board may include a business unit, a switching unit, and a processing unit. The business unit may include at least one business port (e.g., N business ports). The business unit may be connected to a transmission device, or the N business ports may be connected to a transmission device. The business port may be, for example, an Ethernet (ETH) port. The switching unit is used to determine the routing rules of the data after receiving the data, and to route the data to the corresponding port according to the routing rules (e.g., routing data from the business port to the corresponding intermediate frequency port, and / or routing data from the intermediate frequency port to the corresponding business port). The switching unit may also be referred to as a switching chip, such as a field-programmable gate array (FPGA) chip. The processing unit is used to manage the two intermediate frequency boards. The processing unit may also be referred to as a processor, such as a central processing unit (CPU).

[0061] The IF board 1 may include an IF unit 1, which may include at least one modem and at least one IF port (for example, M1 IF ports). The IF board 2 may include an IF unit 2, which may include at least one modem and at least one IF port (for example, M2 IF ports). The M1 IF port and the M2 IF port may be connected to different second communication devices, for example, the M1 IF port is connected to the second communication device 1, and the M2 IF port is connected to the second communication device 2. The modem is used to convert a baseband signal into an IF signal or to convert an IF signal into a baseband signal. The IF port and the modem may correspond one-to-one, or one modem may correspond to multiple IF ports. In the embodiment of the present application, "one-to-one correspondence between IF port and modem" will be used as an example for description.

[0062] As shown in Figure 3, the main control board aggregates all services. Once damaged, the services connected to the entire microwave communication system will not be transmitted normally.

[0063] One possible solution to this problem is to add a second main control board to protect it. This ensures that the entire microwave communication system can continue to operate normally even if one main control board fails. For example, a hot backup main control board can be used. This ensures that the service ports can continue to operate normally even if either the main or backup main control board fails.

[0064] Figure 4A is a schematic diagram of the control plane when hot backup protection is implemented for the main control board. As shown in Figure 4A, the communication device may include main control board 1, main control board 2, and at least one intermediate frequency board (IF board 1 and IF board 2). One of main control board 1 and main control board 2 is the main main control board, and the other is the backup main control board.

[0065] Main control board 1 may include processing unit 1 and, optionally, selection unit 1; main control board 2 may include processing unit 2 and, optionally, selection unit 2. Selection unit 1 and selection unit 2 may communicate to negotiate whether main control board 1 or main control board 2 is the master main control board. Either processing unit 1 or processing unit 2 is connected to IF board 1 and IF board 2 (for example, processing unit 1 and processing unit 2 may be connected to IF board 1 and IF board 2, respectively, via parallel buses); IF board 1 may include selection unit 3, which is used to instruct IF board 1 to obey management commands from the main control board; IF board 2 includes selection unit 4, which is used to instruct IF board 2 to obey management commands from the main control board.

[0066] For example, selection unit 1 and selection unit 2 negotiate to determine that main control board 1 is the master main control board and main control board 2 is the slave main control board. Selection unit 1 can notify processing unit 1 that "main control board 1 is the master main control board and main control board 2 is the slave main control board," and selection unit 2 can notify processing unit 2 that "main control board 1 is the master main control board and main control board 2 is the slave main control board." Furthermore, processing unit 1 can notify selection unit 3 and selection unit 4, respectively, that "the master main control board is main control board 1 and main control board 2 is the slave main control board." Selection unit 3 can then instruct IF board 1 to follow management commands from main control board 1, and selection unit 4 can instruct IF board 2 to follow management commands from main control board 1.

[0067] That is to say, in the structure shown in Figure 4A, the IF board 1 and the IF board 2 are controlled by the processing unit on the main control board. For example, when some basic configurations of the IF board 1 and the IF board 2 are required (such as the modulation mode and modulation bandwidth corresponding to the IF port), if the main control board 1 is the main control board, the processing unit 1 will perform basic configurations on the IF board 1 and the IF board 2 respectively.

[0068] Figure 4B is a schematic diagram of the service plane when hot backup protection is implemented for the main control board. As shown in Figure 4B, the communication device may include main control board 1, main control board 2, and at least one intermediate frequency board (e.g., intermediate frequency board 1 and intermediate frequency board 2). One of main control board 1 and main control board 2 is the main main control board, and the other is the backup main control board.

[0069] The main control board 1 may include a service unit 1 (for example, including N1 service ports), a dual-transmit and receive selection unit 1, and a switching unit 1. The main control board 2 may include a service unit 2 (for example, including N2 service ports), a dual-transmit and receive selection unit 2, and a switching unit 2. The intermediate frequency board 1 may include a dual-transmit and receive selection unit 3, and the intermediate frequency board 2 may include a dual-transmit and receive selection unit 4. It can be understood that the service ports and the dual-transmit and receive selection units can correspond one-to-one, and the intermediate frequency ports and the dual-transmit and receive selection units can also correspond one-to-one. For example, the main control board 1 may include N1 dual-transmit and receive selection units corresponding to N1 service ports. In the embodiment of the present application, only the dual-transmit and receive selection unit 1 is illustrated in Figure 4B. In addition, for a more specific illustration, please refer to Figure 4C. Figure 4C is illustrated by taking the example that the main control board 1 includes 4 service ports, the main control board 2 includes 4 service ports, the intermediate frequency board 1 includes 2 intermediate frequency ports, and the intermediate frequency board 2 includes 2 intermediate frequency ports.

[0070] Taking Figure 4B as an example, in the first transmission direction (i.e., from the service port to the intermediate frequency port), the main control board 1 can send baseband signals to the intermediate frequency board 1 and the intermediate frequency board 2 respectively, and the main control board 2 can also send baseband signals to the intermediate frequency board 1 and the intermediate frequency board 2 respectively; that is, the dual-transmit and receive selection unit 3 of the intermediate frequency board 1 will receive the baseband signals from the main control board 1 and the main control board 2, and the dual-transmit and receive selection unit 4 of the intermediate frequency board 2 will receive the baseband signals from the main control board 1 and the main control board 2.

[0071] When the main control board 1 is the main main control board and the main control board 2 is the backup main control board, the processing unit 1 of the main control board 1 can notify the selection unit 3 and the selection unit 4 respectively that the "main main control board is the main control board 1", and then the selection unit 3 can instruct the dual-transmit and receive selection unit 3 to send the baseband signal of the main control board 1 to the modem 1 after receiving the baseband signals from the main control board 1 and the main control board 2, that is, to select the baseband signal of the main control board 1. The selection unit 4 can instruct the dual-transmit and receive selection unit 2 to send the baseband signal of the main control board 1 to the modem 2 after receiving the baseband signals from the main control board 1 and the main control board 2, that is, to select the baseband signal of the main control board 1.

[0072] In the second transmission direction (i.e., from the intermediate frequency port to the service port), when the main control board 1 is the main main control board and the main control board 2 is the backup main control board, the intermediate frequency board 1 can send baseband signals to the switching unit 1 of the main control board 1 and the switching unit 2 of the main control board 2 respectively. After the switching unit 1 and the switching unit 2 receive the baseband signal of the intermediate frequency board 1, they will send the baseband signal of the intermediate frequency board 1 to the dual-transmit and receive unit 1 of the main control board 1 and / or the dual-transmit and receive unit 1 of the main control board 2 according to the data routing rules (for example, if the data from the intermediate frequency port 1 needs to be routed to the service port of the service unit 1, it can be sent to the dual-transmit and receive unit 1; if the data from the intermediate frequency port 1 needs to be routed to the service port of the service unit 2, it can be sent to the dual-transmit and receive unit 2). The IF board 2 can send baseband signals to the switching unit 1 of the main control board 1 and the switching unit 2 of the main control board 2 respectively. After the switching unit 1 and the switching unit 2 receive the baseband signal of the IF board 2, they will send the baseband signal of the IF board 2 to the dual-transmit and selective-receive unit 1 of the main control board 1 and / or the dual-transmit and selective-receive unit 2 of the main control board 2 according to the data routing rules.

[0073] The selection unit 1 can notify the dual-transmit and receive selection unit 1 that the "main main control board is the main control board 1", and the selection unit 2 can notify the dual-transmit and receive selection unit 2 that the "main main control board is the main control board 1", so that after receiving the baseband signals from the switching unit 1 and the switching unit 2, the dual-transmit and receive selection unit 1 can send the baseband signal from the switching unit 1 to the business unit 1 (that is, select the baseband signal from the switching unit 1); after receiving the baseband signals from the switching unit 1 and the switching unit 2, the dual-transmit and receive selection unit 2 can send the baseband signal from the switching unit 1 to the business unit 2 (that is, select the baseband signal from the switching unit 1).

[0074] It can be understood that the above Figure 4A focuses on describing the units involved in the control plane, and Figure 4B focuses on describing the units involved in the service plane. The first communication device may include the units shown in Figure 4A and the units shown in Figure 4B.

[0075] In FIG. 4A and FIG. 4B , the main control board and the intermediate frequency board are provided separately, which results in a large number of boards after the introduction of the active-standby protection solution.

[0076] Based on this, an embodiment of the present application provides a communication device for integrating a main control board and an intermediate frequency board, and providing active / standby protection for the integrated board, thereby improving the reliability of product applications while increasing integration and reducing the number of boards. The communication device provided in the embodiment of the present application can be an IDU, or can also be a device that includes IDU functionality, such as a device integrated with an IDU.

[0077] Specifically, the communication device provided in the embodiment of the present application (referred to as the first communication device) may include a first circuit board and a second circuit board, and the first circuit board and the second circuit board are mutually active and standby circuit boards, that is, the first circuit board is the active circuit board and the second circuit board is the standby circuit board, or the second circuit board is the active circuit board and the first circuit board is the standby circuit board. The first circuit board includes a service unit 1 (including N1 service ports), an intermediate frequency unit 1 (M1 intermediate frequency ports), a first processing unit and a first switching unit; that is, the first circuit board is an integrated board that integrates the service port, the intermediate frequency port, the processing unit and the switching unit, such as the first circuit board can be an integrated board of the main control board 1 and the intermediate frequency board 1. The second circuit board includes a service unit 2 (including N2 service ports), an intermediate frequency unit 2 (including M2 intermediate frequency ports), a second processing unit and a second switching unit; that is, the second circuit board is an integrated board that integrates the service port, the intermediate frequency port, the processing unit and the switching unit, such as the first circuit board can be an integrated board of the main control board 2 and the intermediate frequency board 2.

[0078] Among them, the M1 intermediate frequency ports or the M2 intermediate frequency ports are used to connect to the second communication device, for example, at least one of the M1 intermediate frequency ports or the M2 intermediate frequency ports is used to receive data from the first service port and send it to the second communication device (such as ODU), and the first service port is a service port among the N1 service ports and the N2 service ports. The N1 service port or the N2 service ports are used to connect to the transmission equipment, for example, at least one of the N1 service port or the N2 service ports is used to receive data from the first intermediate frequency port and send it to the transmission equipment, and the first intermediate frequency port is an intermediate frequency port among the M1 intermediate frequency port and the M2 intermediate frequency ports. That is to say, in the first transmission direction, the data of a service port can be routed to one or more intermediate frequency ports, and then transmitted to the second communication device; in the second transmission direction, the data of one intermediate frequency port can be routed to one or more service ports, and then transmitted to the transmission equipment.

[0079] The specific structures of the communication device are described below through the first and second embodiments respectively.

In this case, the first circuit board and the second circuit board are also connected through W buses, which are parallel buses. The W buses include a W1 bus and a W2 bus; the W1 bus is used for processing unit 1 to manage M2 intermediate frequency ports, and the W2 bus is used for processing unit 2 to manage M1 intermediate frequency ports.

[0084] Furthermore, to allow for bidirectional transmission, at least 2*(M1+N1+M2+N2) buses (which can be serial buses) are required between the first and second circuit boards. Similar to FIG4C , FIG5C illustrates the buses used to transmit data between the two circuit boards when an integrated board is used. FIG5C shows that when the first circuit board includes four service ports and two intermediate frequency ports, and the second circuit board includes four service ports and two intermediate frequency ports, to allow for bidirectional transmission, at least 2*(4+2+4+2)=24 buses are required between the first and second circuit boards.

[0085] It is understood that, under normal circumstances, the maximum transmission bandwidth of each bus is 25Gbps, or 25 Gigabit Ethernet (GE). For example, if the upstream and downstream transmission bandwidths required by service port 1a are both 10GE (less than 25GE), then two cross-board buses can be set for service port 1a (i.e., service port 1a and switching unit 2 are connected via two buses), one of which is used to transmit data from service port 1a to switching unit 2 (i.e., upstream transmission), and the other bus is used to transmit data from switching unit 2 to service port 1a (i.e., downstream transmission).

[0086] Example 2

[0087] In the second embodiment, compared with the first embodiment, by improving the communication method between the first circuit board and the second circuit board, the number of wirings and wiring space can be effectively reduced, thereby saving costs.

[0088] For the control plane, the first circuit board and the second circuit board can be connected via K buses, and the K buses are used for communication between processing unit 1 and processing unit 2. The K buses can be serial buses. For example, if K is 1, processing unit 1 and processing unit 2 communicate via a single serial bus.

[0089] Figure 6A is a schematic diagram of the control surface of a communication device provided in an embodiment of the present application. As shown in Figure 6A, the communication device may include a first circuit board and a second circuit board. The first circuit board includes a processing unit 1, an intermediate frequency unit 1, and a selection unit 1. The processing unit 1 is connected to the intermediate frequency unit 1 (different from the first embodiment, the processing unit 1 does not need to be connected to the intermediate frequency unit 2); the second circuit board includes a processing unit 2, an intermediate frequency unit 2, and a selection unit 2. The processing unit 2 is connected to the intermediate frequency unit 2 (different from the first embodiment, the processing unit 2 does not need to be connected to the intermediate frequency unit 1). The implementation of the selection unit 1 and the selection unit 2 can refer to the above.

[0090] Taking the example where selection unit 1 and selection unit 2 determine through negotiation that the first circuit board is the main circuit board and the second circuit board is the backup circuit board, processing unit 1 can send a management command to processing unit 2 through K buses, and the management command is used to indicate the first type parameters and / or second type parameters of the M2 intermediate frequency ports; wherein the first type parameters of the M2 intermediate frequency ports include at least one of the following: the modulation mode corresponding to the M2 intermediate frequency ports (that is, the modulation mode adopted by the modem corresponding to each of the M2 intermediate frequency ports), the modulation bandwidth corresponding to the M2 intermediate frequency ports, and the transmission power of the M2 intermediate frequency ports; the second type parameters of the M2 intermediate frequency ports include the working status of the M2 intermediate frequency ports, such as whether the working status is on or off.

[0091] The embodiment of the present application does not limit the specific application scenario of "processing unit 1 sending the second type parameters of M2 intermediate frequency ports to processing unit 2". For example, when intermediate frequency unit 1 (i.e., M1 intermediate frequency ports) and intermediate frequency unit 2 (i.e., M2 intermediate frequency ports) operate in a spatial diversity manner (i.e., intermediate frequency unit 1 and intermediate frequency unit 2 transmit the same data), if processing unit 1 configures the working state of intermediate frequency unit 1 to be on and the working state of intermediate frequency unit 2 to be off, then when an abnormality occurs in intermediate frequency unit 1, processing unit 1 can send a management command to processing unit 2 to set the working state of intermediate frequency unit 2 to be on.

[0092] Specifically, processing unit 1 can configure the M1 intermediate frequency ports according to the first type parameters of the M1 intermediate frequency ports; processing unit 2 can configure the M2 intermediate frequency ports according to the first type parameters of the M2 intermediate frequency ports. When processing unit 1 determines that the second type parameters of the M2 intermediate frequency ports need to be modified, it can send a management command to processing unit 2 through K buses. That is to say, for some basic configurations (as opposed to real-time configurations), processing unit 1 and processing unit 2 can each perform some basic configurations on the intermediate frequency ports on this board; and for some real-time configurations, processing unit 1 can send a management command to processing unit 2 in real time to control the M2 intermediate frequency ports. In this way, in Figure 4A, one processing unit is used to configure the IF ports on the two IF boards respectively, that is, the processing unit first configures the IF ports on one of the IF boards, and then configures the IF ports on the other IF board; while in Figure 6A, while the processing unit 1 performs basic configuration on M1 IF ports, the processing unit 2 can perform basic configuration on M2 IF ports, thereby effectively improving the configuration efficiency; moreover, the number of wirings and the wiring space can be reduced (the processing unit 1 does not need to be connected to the IF unit 2, and the processing unit 2 does not need to be connected to the IF unit 1).

[0093] It is understandable that in other possible examples, the processing unit 1 can also send the first type parameters of M2 intermediate frequency ports to the processing unit 2 through K buses, and then after the processing unit 2 receives the first type parameters of the M2 intermediate frequency ports, it configures the M2 intermediate frequency ports.

[0094] On the service side, the first and second circuit boards are connected via a P-root bus, which can be a serial bus (e.g., a high-speed serial bus). The P-root bus includes a P1 bus and a P2 bus. The P1 bus is used for the first circuit board to send service data to the second circuit board, and the P2 bus is used for the second circuit board to send service data to the first circuit board. P is less than 2*(M1+N1+M2+N2). P1 is less than M1+N1+M2+N2, and P2 is less than M1+N1+M2+N2.

[0095] In the embodiments of the present application, the transmission bandwidth of the P1 root bus and the transmission bandwidth of the P2 root bus are not limited, as long as they can meet the needs of the actual scenario. If the transmission bandwidth of the P1 root bus and the transmission bandwidth of the P2 root bus are set too large, it may cause resource waste. For example, the maximum transmission bandwidth required for the first circuit board to send data to the second circuit board is the sum of the uplink transmission bandwidth corresponding to the N1 service ports and M1 intermediate frequency ports, and the downlink transmission bandwidth corresponding to the N2 service ports and M2 intermediate frequency ports. However, in actual scenarios, it may rarely occur that while the N1 service port and M1 intermediate frequency port are performing uplink transmission, the N2 service port and M2 intermediate frequency port are also performing downlink transmission. Therefore, by comprehensively considering the actual scenario and resource consumption, the transmission bandwidth of the P1 root bus can be set to be greater than or equal to the sum of the transmission bandwidths corresponding to the N1 service port and M1 intermediate frequency port; similarly, the transmission bandwidth of the P2 root bus can also be set to be greater than or equal to the sum of the transmission bandwidths corresponding to the N2 service ports and M2 intermediate frequency ports.

[0096] In addition, taking the P1 root bus as an example, the maximum transmission bandwidth of each bus can be 25GE. If the sum of the transmission bandwidths corresponding to N1 service ports and M1 intermediate frequency ports is 20GE (i.e., within the range of (0, 25GE]), then P1 can be equal to 1; if the sum of the transmission bandwidths corresponding to N1 service ports and M1 intermediate frequency ports is 40GE (i.e., within the range of (25GE, 50GE]), then P1 can be equal to 2; if the sum of the transmission bandwidths corresponding to N1 service ports and M1 intermediate frequency ports is 70GE (i.e., within the range of (50GE, 75GE]), then P1 can be equal to 3, and so on.

[0097] Figures 6B to 6D are schematic diagrams of the business side of the communication device provided in an embodiment of the present application. Figure 6B is used to illustrate the connection relationship between different units, Figure 6C is used to illustrate the business data transmission in the first transmission direction, and Figure 6D is used to illustrate the business data transmission in the second transmission direction. As shown in Figure 6B, the communication device may include a first circuit board and a second circuit board, the first circuit board including a business unit 1, a convergence unit 1, a switching unit 1, a transit unit 1, a convergence unit 3, and an intermediate frequency unit 1, and the second circuit board including a business unit 2, a convergence unit 2, a switching unit 2, a transit unit 2, a convergence unit 4, and an intermediate frequency unit 2.

[0098] In addition, selection unit 1 can communicate with transit unit 1, and selection unit 2 can communicate with transit unit 2. For example, after selection unit 1 and selection unit 2 determine through negotiation that the first circuit board is the primary circuit board and the second circuit board is the backup circuit board, selection unit 1 can notify transit unit 1 that "the first circuit board is the primary circuit board and the second circuit board is the backup circuit board," and selection unit 2 can notify transit unit 2 that "the first circuit board is the primary circuit board and the second circuit board is the backup circuit board." Furthermore, after receiving service data from convergence unit 1 or convergence unit 3, transit unit 1 can send the service data to switching unit 1. After receiving service data from convergence unit 2 or convergence unit 4, transit unit 2 can send the service data to transit unit 1, which then sends the data to switching unit 1.

[0099] The following takes "the first circuit board is the main circuit board and the second circuit board is the backup circuit board" as an example to introduce service data transmission in the first transmission direction and the second transmission direction.

[0100] As shown in FIG6C , in the first transmission direction (i.e., from the service port to the IF port), the service data of N1 service ports are aggregated by aggregation unit 1 (for example, taking data packet 1 of service port 1 as an example, aggregation unit 1 can add an aggregation header to data packet 1 of service port 1, and the aggregation header can include an identifier of service port 1) and then sent to transit unit 1. After transit unit 1 determines that the first circuit board is the primary circuit board and the second circuit board is the backup circuit board, it can send the aggregated service data to switching unit 1.

[0101] The service data of N2 service ports is aggregated by aggregation unit 2 and sent to transit unit 2. After transit unit 2 determines that the first circuit board is the master circuit board and the second circuit board is the backup circuit board, it can send the aggregated service data to transit unit 1 through the P2 root bus. Then, transit unit 1 can send the aggregated service data to switching unit 1.

[0102] After the switching unit 1 receives the aggregated service data (which may include service data of N1 service ports and service data of N2 service ports), it can send the service data to the aggregation unit 3 and / or the transit unit 1 according to the routing rules of the data. For example, the switching unit 1 determines that the intermediate frequency port corresponding to the data packet 1 is the intermediate frequency port 1 (the intermediate frequency port 1 belongs to the M1 intermediate frequency ports) according to the routing rules of the data packet 1, and then the switching unit 1 can change the identifier of the service port in the aggregation header of the data packet 1 to the identifier of the intermediate frequency port 1, and send the data packet 1 to the aggregation unit 3. After the aggregation unit 3 receives the data packet 1, it can parse the aggregation header and send the data packet 1 to the intermediate frequency port 1 according to the identifier of the intermediate frequency port 1 included in the aggregation header. Then the intermediate frequency port 1 sends the data packet 1 to the second communication device (i.e., ODU). Exemplarily, the data packet can include the routing rules of the data packet, and the switching unit 1 can parse the data packet to obtain the routing rules.

[0103] For another example, the switching unit 1 determines that the intermediate frequency port corresponding to the data packet 2 is the intermediate frequency port 2 (the intermediate frequency port 2 belongs to M2 intermediate frequency ports) according to the routing rule of the data packet 2, and then the switching unit 1 can change the identifier of the service port in the aggregation header of the data packet 2 to the identifier of the intermediate frequency port 2, and send the data packet 2 to the transit unit 1, and then the transit unit 1 sends the data packet 2 to the transit unit 2, and the transit unit 2 sends the data packet 2 to the aggregation unit 4. After receiving the data packet 2, the aggregation unit 4 can parse the aggregation header and send the data packet 2 to the intermediate frequency port 2 according to the identifier of the intermediate frequency port 2 included in the aggregation header, and then the intermediate frequency port 2 sends the data packet 2 to the second communication device.

[0104] As shown in FIG6D , in the second transmission direction (i.e., from the IF port to the service port), the service data of M1 IF ports are aggregated by the aggregation unit 3 (for example, taking data packet 3 of IF port 1 as an example, the aggregation unit 3 can add an aggregation header to data packet 3 of IF port 1, and the aggregation header can include the identifier of IF port 1), and then sent to the transit unit 1. After the transit unit 1 determines that the first circuit board is the master circuit board and the second circuit board is the backup circuit board, it can send the aggregated service data to the switching unit 1.

[0105] The service data of the M2 IF ports is aggregated by the aggregation unit 4 and sent to the transit unit 2. After the transit unit 2 determines that the first circuit board is the master circuit board and the second circuit board is the backup circuit board, it can send the aggregated service data to the transit unit 1 through the P1 root bus. Then, the transit unit 1 can send the aggregated service data to the switching unit 1.

[0106] After receiving the aggregated service data, the switching unit 1 can send the data to the aggregation unit 1 and / or the transit unit 1 according to the routing rules of the data. For example, the switching unit 1 determines that the service port corresponding to the data packet 3 is the service port 1 (the service port 1 belongs to N1 service ports) according to the routing rules of the data packet 3, and then the switching unit 1 can change the identifier of the intermediate frequency port in the aggregation header of the data packet 3 to the identifier of the service port 1, and send the data packet 3 to the aggregation unit 1. After receiving the data packet 3, the aggregation unit 1 can parse the aggregation header and send the data packet 1 to the service port 1 according to the identifier of the service port 1 included in the aggregation header, and then the service port 1 sends the data packet 3 to the transmission device.

[0107] For another example, the switching unit 1 determines that the service port corresponding to the data packet 4 is the service port 2 (the service port 2 belongs to N2 service ports) according to the routing rule of the data packet 4, and then the switching unit 1 can change the identifier of the intermediate frequency port in the aggregation header of the data packet 4 to the identifier of the service port 2, and send the data packet 4 to the transit unit 1, and then the transit unit 1 sends the data packet 4 to the transit unit 2, and the transit unit 2 sends the data packet 4 to the aggregation unit 2. After receiving the data packet 4, the aggregation unit 2 can parse the aggregation header and send the data packet 4 to the service port 2 according to the identifier of the service port 2 included in the aggregation header, and then the service port 2 sends the data packet 2 to the transmission device.

[0108] Furthermore, it is understood that after selection unit 1 and selection unit 2 determine through negotiation that the first circuit board is the primary circuit board and the second circuit board is the backup circuit board, if the hardware of the first circuit board fails, selection unit 1 and selection unit 2 can determine through negotiation that the second circuit board is the primary circuit board and the first circuit board is the backup circuit board. Furthermore, on the control side, the second circuit board can listen via K buses and remove services that require cross-board configuration before the first circuit board returns to normal; on the service side, the second circuit board no longer receives service data from the first circuit board, but instead exchanges and processes service data for this board (and other boards).

[0109] As can be seen from the description of Figures 6B to 6D above, taking the first circuit board as an example, the first circuit board in Example 2 adds a convergence unit and a transfer unit compared to the first circuit board in Example 1, without the need for a dual-transmit and receive selective unit. Since the convergence unit and transfer unit are respectively provided on the two circuit boards in Example 2, data transmission between the two circuit boards is achieved through the two transfer units. Specifically, the first circuit board can send service data to the second circuit board via the P1 bus. That is, service data from different service ports and intermediate frequency ports on the first circuit board can be sent to the second circuit board (for example, to the switching unit of the second circuit board) via the P1 bus, and different service ports and intermediate frequency ports on the second circuit board can receive service data from the first circuit board (for example, receiving service data from the switching unit of the first circuit board) via the P1 bus. For example, if P1 = 1, service data from different service ports and intermediate frequency ports on the first circuit board are sent to the second circuit board via the same bus, and service data from different service ports and intermediate frequency ports on the second circuit board are received from the first circuit board via the same bus. Therefore, compared to the approach in Figure 5C where "service data from different service ports and IF ports on the first circuit board are sent to the second circuit board via different buses," P1 can be less than M1+N1+M2+N2. Similarly, P2 can also be less than M1+N1+M2+N2, meaning P can be less than 2*(M1+N1+M2+N2), effectively reducing the amount of cross-board wiring and wiring space. Furthermore, in Example 2, there is no need to provide a dual-transmitter / receiver selection unit, making implementation relatively simple, significantly reducing costs in the active / standby model.
