Description

Technical Field

[0001] 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

[0002] Microwave communication is the communication that uses microwaves as a medium. It does not require solid media. Microwave transmission can be used when there is no obstacle in the straight-line distance between two points. Microwave communication has large capacity, good quality and can be transmitted over long distances. Therefore, microwave communication is an important means of communication network and is also widely applicable to various special communication networks.

[0003] At present, a microwave communication system may include an indoor unit (IDU) and an outdoor unit (ODU). The IDU may include a main control board and at least one intermediate frequency board. The main control board may include multiple service ports, which are used to receive and / or send baseband signals (or service signals). The intermediate frequency board may include multiple intermediate frequency ports, which are used to receive and / or send intermediate frequency signals.

[0004] However, since the main control board aggregates all services, once the main control board is damaged, the services accessed on the entire microwave communication system will not be transmitted normally. Summary of the invention

[0005] The embodiments of the present application provide a communication device, microwave communication equipment and system for realizing primary-standby protection and improving the reliability of product applications.

[0006] 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 an IDU function, 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, and 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 ports or the M2 intermediate frequency ports are used to connect to a second communication device; the first circuit board is a main circuit board, and the second circuit board is a standby circuit board; or the second circuit board is a main circuit board, and the first circuit board is a standby circuit board.

[0007] In this way, since the first circuit board and the second circuit board can be each other's main and standby circuit boards, the main and standby protection can be realized, and the reliability of product application can be improved. In addition, since the first circuit board can be integrated with the service port and the intermediate frequency port, and the second circuit board can be integrated with the service port and the intermediate frequency port, that is, the first circuit board and the second circuit board are both integrated boards, which can effectively improve the integration.

[0008] In one possible design, the first circuit board and the second circuit board are connected via a P root bus, the P root bus 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).

[0009] In this way, the first circuit board can send service data to the second circuit board through the P1 root bus, that is, the service data of different service ports and intermediate frequency ports on the first circuit board can be sent to the second circuit board (such as the switching unit of the second circuit board) through the P1 root bus, and the different service ports and intermediate frequency ports on the second circuit board can receive service data from the first circuit board through the P1 root bus (such as receiving service data from the switching unit of the first circuit board); for example, if P1=1, the service data of different service ports and intermediate frequency ports on the first circuit board are sent to the second circuit board through the same bus, and the different service ports and intermediate frequency ports on the second circuit board receive service data from the first circuit board through the same bus. Therefore, compared with the method of "the service data of different service ports and intermediate frequency ports on the first circuit board are sent to the second circuit board through different buses respectively", P1 can be less than M1+N1+M2+N2, and similarly, P2 can also be less than M1+N1+M2+N2, that is, P can be less than 2*(M1+N1+M2+N2), so that the number of wiring and wiring space can be effectively reduced.

[0010] In one possible design, the P-root bus is a serial bus.

[0011] 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.

[0012] 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 the M1 intermediate frequency ports and the downlink transmission bandwidth corresponding to the N2 service ports and the M2 intermediate frequency ports. However, in actual scenarios, it may rarely happen that while the N1 service ports and the M1 intermediate frequency ports are performing uplink transmission, the N2 service ports and the M2 intermediate frequency ports 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 ports and the M1 intermediate frequency ports; 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.

[0013] 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.

[0014] 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.

[0015] In one possible design, the first switching unit is used to: receive the first service data, and if it is determined that the routing port of the first service data is a port on the second circuit board, send the first service data to the second circuit board through the P1 root bus.

[0016] In a 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.

[0017] In a 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.

[0018] 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.

[0019] In one possible design, the K buses are serial buses.

[0020] 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 for the first processing unit to send management commands to the second processing unit; the management commands are used to indicate 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.

[0021] In this way, the management command sent by the first processing unit to the second processing unit may include a variety of possible parameters, thereby making the implementation more flexible.

[0022] In one possible design, the first circuit board and the second circuit board are also connected via W root buses, and the W root buses include a W1 root bus and a W2 root bus; the W1 root bus is used by the first processing unit to manage the M2 intermediate frequency ports, and the W2 root bus is used by the second processing unit to manage the M1 intermediate frequency port.

[0023] In one possible design, the W buses are parallel buses.

[0024] 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.

[0025] 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; 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.

[0041] First, some terms in the embodiments of the present application are explained to facilitate understanding by those skilled in the art.

[0042] (1)Microwave communication

[0043] Microwave communication refers to a communication method that uses microwaves for communication. Microwaves are electromagnetic waves with a frequency range of 300 megahertz (MHz) to 3 terahertz (THz), 1THz = 1000 gigahertz (GHz), and a wavelength range of 1 meter to 0.1 millimeter (speed of light = wavelength × frequency); that is, microwaves have high frequencies and short wavelengths.

[0044] (2) Double send and receive

[0045] In microwave communication systems, in order to improve communication reliability, a 1+1 hot standby (HSB) method is usually selected. That is, for two sets of equipment, the working frequency is the same, and only one set of equipment is working. When the equipment fails, the other set of backup equipment takes over the work of the equipment, thereby ensuring the reliability of communication.

[0046] In a hot backup system, the sending side can copy one signal to two outputs (i.e., dual sending), and the receiving side can select one of the two channels to receive (i.e., selective receiving).

[0047] (3) Serial bus and parallel bus

[0048] The bus can be understood as a group of public 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 the components can be shared in a time-sharing manner through this group of lines; time-sharing means that only one component is allowed to send information to the bus at the same time. If there are multiple components in the system, they can only send information to the bus in a time-sharing manner.

[0049] According to the different transmission formats, buses can be divided into serial buses and parallel buses. Figure 1A As shown, information is transmitted between device A and device B via a serial bus. The serial bus transmits information in a serial manner (ie, transmits data one bit at a time). Therefore, the serial bus only needs one signal line to be implemented. Figure 1B As shown, information is transmitted between device C and device D via a parallel bus. The parallel bus transmits information in a parallel manner (ie, it can transmit multiple bits of data simultaneously). Therefore, the parallel bus requires multiple signal lines to be implemented.

[0050] (4) Uplink and downlink transmission

[0051] 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.

[0052] Figure 2 A schematic diagram of a microwave communication system provided in an embodiment of the present application. Figure 2As shown, the microwave communication system may include a first communication device, one or more second communication devices connected to the first communication device, and a plurality of antenna systems ( Figure 2 In the figure, a first communication device is connected to two second communication devices, namely the second communication device 1 and the second communication device 2, for example.

[0053] 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. Exemplarily, the first communication device may be an IDU, or may be a device including an IDU function, such as a device integrated with an IDU; the second communication device may be an ODU, or may be a device including an ODU function, such as a device integrated with an ODU.

[0054] In the first transmission direction, the first communication device is used to modulate the baseband signal (or service signal) from the transmission device, convert the baseband signal into an intermediate frequency signal, and send it to the second communication device through an intermediate frequency cable; the transmission device can be, for example, a router. The second communication device is used to convert the intermediate frequency signal into a microwave signal and amplify it, and then send it out through the antenna system.

[0055] In the second transmission direction, the antenna system sends the received microwave signal to the second communication device, which converts the microwave signal into an intermediate frequency signal and transmits the intermediate frequency signal to the first communication device through the intermediate frequency cable. The first communication device demodulates the intermediate frequency signal, converts the intermediate frequency signal into a baseband signal, and sends it to the transmission device.

[0056] exist Figure 2 In the microwave communication system shown, the first communication device may include a main control board and at least one intermediate frequency board. Figure 3 As shown, the first communication device may include a main control board and two intermediate frequency boards (intermediate frequency board 1 and intermediate frequency board 2 respectively).

[0057] The main control board may include a business unit, a switching unit and a processing unit. Among them, the business unit may include at least one business port (such as N business ports). The business unit can be connected to the transmission device or the N business ports can be connected to the transmission device; the business port can 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 route the data to the corresponding port according to the routing rules of the data (such as routing the data from the business port to the corresponding intermediate frequency port, and / or, routing the data from the intermediate frequency port to the corresponding business port); the switching unit can also be called 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 can also be called a processor, such as a central processing unit (CPU).

[0058] The intermediate frequency board 1 may include an intermediate frequency unit 1, and the intermediate frequency unit 1 may include at least one modem and at least one intermediate frequency port (for example, M1 intermediate frequency ports). The intermediate frequency board 2 may include an intermediate frequency unit 2, and the intermediate frequency unit 2 may include at least one modem and at least one intermediate frequency port (for example, M2 intermediate frequency ports). The M1 intermediate frequency port and the M2 intermediate frequency port may be connected to different second communication devices, for example, the M1 intermediate frequency port is connected to the second communication device 1, and the M2 intermediate frequency port is connected to the second communication device 2. The modem is used to convert a baseband signal into an intermediate frequency signal or to convert an intermediate frequency signal into a baseband signal. The intermediate frequency port and the modem may correspond one-to-one, or one modem may correspond to multiple intermediate frequency ports. In the embodiment of the present application, "one-to-one correspondence between intermediate frequency ports and modems" will be used as an example for description.

[0059] according to Figure 3 It can be seen that the main control board aggregates all services. Once it is damaged, the services connected to the entire microwave communication system will not be able to be transmitted normally.

[0060] A possible solution to this problem is to add a main control board to protect it, so that the entire microwave communication system can still work normally when one main control board is damaged. For example, the main control board can be hot-backed up, so that the service port can work normally when either the main control board or the backup control board is damaged.

[0061] Figure 4A This is a schematic diagram of the control surface when hot backup protection is performed on the main control board. Figure 4AAs shown, the communication device may include a main control board 1, a main control board 2 and at least one intermediate frequency board (such as intermediate frequency board 1 and intermediate frequency board 2), one of the main control boards 1 and the main control board 2 is the main main control board, and the other main control board is the standby main control board.

[0062] The main control board 1 may include a processing unit 1, and optionally, a selection unit 1; the main control board 2 may include a processing unit 2, and optionally, a selection unit 2. The selection unit 1 and the selection unit 2 may communicate, and then negotiate whether the main control board 1 is the main main control board or the main control board 2 is the main main control board. Any one of the processing unit 1 and the processing unit 2 is connected to the intermediate frequency board 1 and the intermediate frequency board 2 (for example, the processing unit 1 and the processing unit 2 can be connected to the intermediate frequency board 1 and the intermediate frequency board 2 respectively through a parallel bus); the intermediate frequency board 1 may include a selection unit 3, and the selection unit 3 is used to instruct the intermediate frequency board 1 to obey the management command of the main main control board, and the intermediate frequency board 2 includes a selection unit 4, and the selection unit 4 is used to instruct the intermediate frequency board 2 to obey the management command of the main main control board.

[0063] For example, selection unit 1 and selection unit 2 determine through negotiation that main control board 1 is the main main control board and main control board 2 is the standby main control board. Selection unit 1 can notify processing unit 1 that "main control board 1 is the main main control board and main control board 2 is the standby main control board", and selection unit 2 can notify processing unit 2 that "main control board 1 is the main main control board and main control board 2 is the standby main control board". Furthermore, processing unit 1 can notify selection unit 3 and selection unit 4 respectively that "the main main control board is main control board 1 and main control board 2 is the standby main control board", and selection unit 3 can instruct intermediate frequency board 1 to obey the management command of main control board 1, and selection unit 4 can instruct intermediate frequency board 2 to obey the management command of main control board 1.

[0064] That is to say, Figure 4A In the structure shown, 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.

[0065] Figure 4B This is a business diagram for hot backup protection of the main control board. Figure 4B As shown, the communication device may include a main control board 1, a main control board 2 and at least one intermediate frequency board (such as intermediate frequency board 1 and intermediate frequency board 2), one of the main control boards 1 and the main control board 2 is the main main control board, and the other main control board is the standby main control board.

[0066] The main control board 1 may include a service unit 1 (for example, including N1 service ports), a dual-transmitting and receiving selective 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-transmitting and receiving selective unit 2, and a switching unit 2. The intermediate frequency board 1 may include a dual-transmitting and receiving selective unit 3, and the intermediate frequency board 2 may include a dual-transmitting and receiving selective unit 4. It can be understood that the service ports and the dual-transmitting and receiving selective units may correspond one-to-one, and the intermediate frequency ports and the dual-transmitting and receiving selective units may also correspond one-to-one. For example, the main control board 1 may include N1 dual-transmitting and receiving selective units corresponding to N1 service ports. In the embodiment of the present application, Figure 4B Only the dual-transmitting and selective receiving unit 1 is shown in FIG. Figure 4C , Figure 4C It 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.

[0067] by Figure 4B For 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 selective-receive 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 selective-receive 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.

[0068] When main control board 1 is the main main control board and main control board 2 is the standby main control board, processing unit 1 of main control board 1 can notify selection unit 3 and selection unit 4 respectively that "main main control board is main control board 1", and then selection unit 3 can instruct dual-transmission and selection unit 3 to send the baseband signal of main control board 1 to modem 1 after receiving the baseband signals of main control board 1 and main control board 2, that is, to select and receive the baseband signal of main control board 1, and selection unit 4 can instruct dual-transmission and selection unit 2 to send the baseband signal of main control board 1 to modem 2 after receiving the baseband signals of main control board 1 and main control board 2, that is, to select and receive the baseband signal of main control board 1.

[0069] 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 intermediate frequency 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. When the switching unit 1 and the switching unit 2 receive the baseband signal of the intermediate frequency board 2, they will send the baseband signal of the intermediate frequency 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.

[0070] The selection unit 1 can notify the dual-transmitting and receiving selection unit 1 that "the main main control board is the main control board 1", and the selection unit 2 can notify the dual-transmitting and receiving selection unit 2 that "the main main control board is the main control board 1", and then the dual-transmitting and receiving selection unit 1 can send the baseband signal from the switching unit 1 to the business unit 1 (i.e., select the baseband signal from the switching unit 1) after receiving the baseband signal from the switching unit 1 and the switching unit 2; the dual-transmitting and receiving selection unit 2 can send the baseband signal from the switching unit 1 to the business unit 2 (i.e., select the baseband signal from the switching unit 1) after receiving the baseband signal from the switching unit 1 and the switching unit 2.

[0071] It is understandable that the above Figure 4A The focus is on describing the units involved in the control plane. Figure 4B The description focuses on the units involved in the business plane. The first communication device may include Figure 4A The units shown in Figure 4B The unit shown in .

[0072] Above Figure 4A and Figure 4B In the present invention, the main control board and the intermediate frequency board are set separately, which will result in a large number of boards after the introduction of the active-standby protection solution.

[0073] 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 performing master-slave protection on the integrated board, thereby improving the reliability of product applications while increasing the integration level and reducing the number of single boards. The communication device provided in the embodiment of the present application may be an IDU, or may be a device including an IDU function, such as a device integrated with an IDU.

[0074] 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 master and standby circuit boards, that is, the first circuit board is the master circuit board and the second circuit board is the standby circuit board, or the second circuit board is the master 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 integrating a service port, an intermediate frequency port, a processing unit and a switching unit, such as the first circuit board can be an integrated board of a main control board 1 and an 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 integrating a service port, an intermediate frequency port, a processing unit and a switching unit, such as the first circuit board can be an integrated board of a main control board 2 and an intermediate frequency board 2.

[0075] Among them, M1 intermediate frequency ports or M2 intermediate frequency ports are used to connect to the second communication device, for example, at least one intermediate frequency port among the M1 intermediate frequency ports or 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 N2 service ports. N1 service ports or N2 service ports are used to connect to transmission equipment, for example, at least one service port among the N1 service ports or 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 ports and 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 an intermediate frequency port can be routed to one or more service ports, and then transmitted to the transmission equipment.

[0076] The specific structure of the communication device is described below through Embodiment 1 and Embodiment 2 respectively.

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

Figure 5B As shown, the communication device may include a first circuit board and a second circuit board, the first circuit board may include a service unit 1, a dual-transmitting and receiving selection unit 1, a switching unit 1 and a dual-transmitting and receiving selection unit 3, and the second circuit board may include a service unit 2, a dual-transmitting and receiving selection unit 2, a switching unit 2 and a dual-transmitting and receiving selection unit 4. The specific implementation of the communication between the various units and the data transmission can refer to Figure 4A and Figure 4B Description in .

[0081] In addition, considering the bidirectional transmission, at least 2*(M1+N1+M2+N2) buses (which can be serial buses) are required between the first circuit board and the second circuit board. Figure 4C , Figure 5C The diagram shows the bus used to transmit data between two circuit boards when an integrated board is used. Figure 5C It can be seen that when the first circuit board includes 4 service ports and 2 intermediate frequency ports and the second circuit board includes 4 service ports and 2 intermediate frequency ports, considering bidirectional transmission, at least 2*(4+2+4+2)=24 buses are required between the first circuit board and the second circuit board.

[0082] It is understandable that, under normal circumstances, the maximum transmission bandwidth of each bus is 25Gbps, or 25 Gigabit Ethernet (GE). For example, if the uplink and downlink transmission bandwidths required by service port 1a are both 10GE (less than 25GE), then for service port 1a, two cross-board buses can be set (i.e., service port 1a and switching unit 2 are connected through two buses), one of which is used for service port 1a to transmit data to switching unit 2 (i.e., uplink transmission), and the other bus is used for switching unit 2 to transmit data to service port 1a (i.e., downlink transmission).

[0083] Embodiment 2

[0084] 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 the wiring space can be effectively saved, thereby saving costs.

[0085] For the control plane, the first circuit board and the second circuit board may be connected via K buses, and the K buses are used for communication between processing unit 1 and processing unit 2. The K buses may be serial buses, for example, K is equal to 1, that is, processing unit 1 and processing unit 2 communicate via one serial bus.

[0086] Fig. 6A This is a schematic diagram of the control plane of a communication device provided in an embodiment of the present application. Fig. 6A As shown, 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.

[0087] Taking the example that 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 via K buses, and the management command is used to indicate the first type parameters and / or second type parameters of 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.

[0088] 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) work 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 intermediate frequency unit 1 is abnormal, 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.

[0089] 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 management commands to processing unit 2 in real time to control the M2 intermediate frequency ports. In this way, Figure 4A In the example, one processing unit configures the IF ports on two IF boards respectively, that is, the processing unit first configures the IF port on one IF board, and then configures the IF port on the other IF board; Fig. 6A In the embodiment, while processing unit 1 performs basic configuration on M1 intermediate frequency ports, processing unit 2 can perform basic configuration on M2 intermediate frequency ports, thereby effectively improving configuration efficiency; moreover, the number of wirings and wiring space can be reduced (processing unit 1 does not need to be connected to intermediate frequency unit 2, and processing unit 2 does not need to be connected to intermediate frequency unit 1).

[0090] It is understandable that in other possible examples, processing unit 1 can also send the first type parameters of M2 intermediate frequency ports to processing unit 2 through K buses, and then after processing unit 2 receives the first type parameters of the M2 intermediate frequency ports, it configures the M2 intermediate frequency ports.

[0091] For the business side, the first circuit board and the second circuit board are connected through a P-root bus, which can be a serial bus (such as a high-speed serial bus). The P-root bus 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). wherein, P1 is less than M1+N1+M2+N2; and P2 is less than M1+N1+M2+N2.

[0092] In the embodiment 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 a waste of resources. 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 the M1 intermediate frequency ports and the downlink transmission bandwidth corresponding to the N2 service ports and the M2 intermediate frequency ports, but it may rarely occur in the actual scenario that while the N1 service ports and the M1 intermediate frequency ports are performing uplink transmission, the N2 service ports and the M2 intermediate frequency ports 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 ports and the M1 intermediate frequency ports; 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.

[0093] 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.

[0094] FIG. 6B to FIG. 6D A schematic diagram of the service interface of a communication device provided in an embodiment of the present application. Figure 6B Used to illustrate the connection relationship between different units. Figure 6C used to indicate the business data transmission in the first transmission direction, Fig.6D It is used to indicate the service data transmission in the second transmission direction. Figure 6B As shown, the communication device may include a first circuit board and a second circuit board, the first circuit board includes 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 includes 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.

[0095] In addition, the selection unit 1 can communicate with the transit unit 1, and the selection unit 2 can communicate with the transit unit 2. For example, after the selection unit 1 and the 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, the selection unit 1 can notify the transit unit 1 that "the first circuit board is the main circuit board and the second circuit board is the backup circuit board", and the selection unit 2 can notify the transit unit 2 that "the first circuit board is the main circuit board and the second circuit board is the backup circuit board". Furthermore, after receiving the service data from the convergence unit 1 or the convergence unit 3, the transit unit 1 can send the service data to the switching unit 1; after receiving the service data from the convergence unit 2 or the convergence unit 4, the transit unit 2 can send the service data to the transit unit 1, and the transit unit 1 sends it to the switching unit 1.

[0096] 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 the service data transmission in the first transmission direction and the second transmission direction.

[0097] See also Figure 6C As shown, in the first transmission direction (i.e., from the service port to the intermediate frequency port), the service data of N1 service ports are aggregated by the aggregation unit 1 (for example, taking the data packet 1 of the service port 1 as an example, the aggregation unit 1 can add an aggregation header to the data packet 1 of the service port 1, and the aggregation header can include the identification of the service port 1), and then sent to the transit unit 1. After the transit unit 1 determines that the first circuit board is the main circuit board and the second circuit board is the standby circuit board, the aggregated service data can be sent to the switching unit 1.

[0098] The service data of N2 service ports are aggregated by the aggregation unit 2 and sent to the transit unit 2. After the transit unit 2 determines that the first circuit board is the main circuit board and the second circuit board is the backup circuit board, the aggregated service data can be sent to the transit unit 1 through the P2 root bus, and then the transit unit 1 can send the aggregated service data to the switching unit 1.

[0099] 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 may send the service data to the aggregation unit 3 and / or the transit unit 1 according to the data routing rules. For example, the switching unit 1 determines that the intermediate frequency port corresponding to the data packet 1 is the intermediate frequency port 1 (intermediate frequency port 1 belongs to M1 intermediate frequency ports) according to the routing rules of the data packet 1, and then the switching unit 1 may 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 may parse the aggregation header, and according to the identifier of the intermediate frequency port 1 included in the aggregation header, send the data packet 1 to the intermediate frequency port 1, and then the intermediate frequency port 1 sends the data packet 1 to the second communication device (i.e., ODU). Exemplarily, the data packet may include the routing rules of the data packet, and the switching unit 1 may parse the data packet to obtain the routing rules.

[0100] 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 according to the identifier of the intermediate frequency port 2 included in the aggregation header, send the data packet 2 to the intermediate frequency port 2, and then the intermediate frequency port 2 sends the data packet 2 to the second communication device.

[0101] See also Fig.6D As shown, in the second transmission direction (i.e., from the intermediate frequency port to the service port), the service data of M1 intermediate frequency ports are aggregated by the aggregation unit 3 (for example, taking the data packet 3 of the intermediate frequency port 1 as an example, the aggregation unit 3 can add an aggregation header to the data packet 3 of the intermediate frequency port 1, and the aggregation header can include the identification of the intermediate frequency port 1), and then sent to the transit unit 1. After the transit unit 1 determines that the first circuit board is the main circuit board and the second circuit board is the standby circuit board, the aggregated service data can be sent to the switching unit 1.

[0102] The service data of the M2 intermediate frequency ports are aggregated by the aggregation unit 4 and sent to the transfer unit 2. After the transfer unit 2 determines that the first circuit board is the main circuit board and the second circuit board is the backup circuit board, the aggregated service data can be sent to the transfer unit 1 through the P1 root bus, and then the transfer unit 1 can send the aggregated service data to the switching unit 1.

[0103] 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 according to the identifier of the service port 1 included in the aggregation header, send the data packet 1 to the service port 1, and then the service port 1 sends the data packet 3 to the transmission device.

[0104] For another example, switching unit 1 determines that the service port corresponding to data packet 4 is service port 2 (service port 2 belongs to N2 service ports) according to the routing rule of data packet 4, and then switching unit 1 can change the identifier of the intermediate frequency port in the aggregation header of data packet 4 to the identifier of service port 2, and send data packet 4 to transit unit 1, and then transit unit 1 sends data packet 4 to transit unit 2, and transit unit 2 sends data packet 4 to aggregation unit 2. After receiving data packet 4, aggregation unit 2 can parse the aggregation header, and according to the identifier of service port 2 included in the aggregation header, send data packet 4 to service port 2, and then service port 2 sends data packet 2 to the transmission device.

[0105] In addition, it can be understood that after the selection unit 1 and the 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, if the hardware of the first circuit board fails, the selection unit 1 and the selection unit 2 can determine through negotiation that the second circuit board is the main circuit board and the first circuit board is the backup circuit board. In addition, on the control side, the second circuit board can listen through K buses and remove the 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 the service data of the first circuit board, but exchanges and processes the service data of this board (and other single boards).

[0106] According to the above FIG. 6B to FIG. 6DFrom the introduction, it can be seen that, taking the first circuit board as an example, compared with the first circuit board in Example 1, the first circuit board in Example 2 adds a convergence unit and a transfer unit, and there is no need to set a dual-transmitting and selective receiving unit. Since the convergence unit and the transfer unit are respectively set on the two circuit boards in Example 2, the data transmission between the two circuit boards is realized through the two transfer units. Specifically, the first circuit board can send service data to the second circuit board through the P1 root bus, that is, the service data of different service ports and intermediate frequency ports on the first circuit board can be sent to the second circuit board through the P1 root bus (for example, sent to the switching unit of the second circuit board), and the different service ports and intermediate frequency ports on the second circuit board can receive service data from the first circuit board through the P1 root bus (for example, receiving service data from the switching unit of the first circuit board); for example, P1=1, then the service data of different service ports and intermediate frequency ports on the first circuit board are sent to the second circuit board through the same bus, and the different service ports and intermediate frequency ports on the second circuit board receive service data from the first circuit board through the same bus. Therefore, compared to Figure 5C For the method of "the business data of different business ports and intermediate frequency ports on the first circuit board are sent to the second circuit board through different buses respectively", P1 can be less than M1+N1+M2+N2, and 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 cross-board wiring and wiring space. In addition, in the second embodiment, there is no need to set up a dual-transmitting and selective receiving unit, which is relatively simple to implement, thereby significantly reducing the cost under the active-standby model.
