[0030] Embodiment 1

[0031] The embodiments of the present disclosure provide a multi-modal communication base station.

[0032] Specifically, referring to Figure 1The multi-mode communication base station comprises a controller 102, a switch 100, a router 200 and at least two baseband units 103, the frequency bands of the baseband units 103 are different;

[0033] The switch 100 comprises at least four Ethernet interfaces 101, and the router 200 comprises at least a WAN interface and a LAN interface;

[0034] Each of the Ethernet interfaces 101 is connected to the controller 102, the LAN interface 201 and each of the baseband units 103 one by one;

[0035] The WAN interface 202 is used to connect to the core network of a communication network;

[0036] The controller 102 is configured to start each of the baseband units 103 according to a received control instruction, so that each of the baseband units 103 works in different frequency bands in time.

[0037] In the embodiment, the baseband units (BBUs) can be baseband units responsible for different telecom operators respectively, each of the baseband units 103 has the same hardware structure, and different working frequency bands are set by software codes. Specifically, the telecom operators can be domestic telecom operators and / or foreign telecom operators. For example, the domestic telecom operators can be domestic operators such as Mobile, Telecom and Unicom. For example, there can be two baseband units 103, one baseband unit 103 is a baseband unit for a Mobile operator, and the corresponding frequency band is the frequency band owned by the Mobile operator. The other baseband unit 103 is a baseband unit for a Telecom operator, and the corresponding frequency band is the frequency band owned by the Telecom operator. Each of the baseband units 103 can be a 5G base station unit, a 4G base station unit or a higher level base station unit, which is not limited here.

[0038] In the embodiment, the wide area network (WAN) interface can also be referred to as a wide area network port, and the local area network (LAN) interface can also be referred to as a local network port.

[0039] In the embodiment, the plurality of baseband units are connected to the master board, power amplifier and other devices in a compact manner, radio frequency columns are used to realize radio frequency interconnection, connectors are used to realize power and signal interconnection, and the use of cables causes the system to have more, chaotic and unstable cables, thereby reducing the size of the equipment.

[0040] In the embodiment, the controller 102 opens different baseband units 103 according to the requirements of the upper management system of the communication network, so that each baseband unit 103 works in different frequency bands in time sharing mode, and different operators work in different frequency bands in time sharing mode. Different operators do not need to deploy different communication base stations respectively, and the multi-modal communication base station provided in the embodiment can realize that different operator base station units work in different frequency bands in time sharing mode, improve the integration of the communication base station, and reduce the deployment cost of the base station.

[0041] In the embodiment, the router is used for routing control, and the core network only needs to allocate an IP address to the router 200. The router 200 and the switch 100 constitute a local area network, and the router 200 sets the internal network IP addresses of the controller and each Ethernet interface. The isolation and management of the WAN interface and the LAN interface are realized by the router.

[0042] In an embodiment, the router can use MT7621, and the controller can use an ARM chip.

[0043] Since there are multiple baseband units 103, in order to ensure that each baseband unit 103 can work smoothly, the controller 102 controls each baseband unit 103. Specifically, the controller 102 is configured to restart a target baseband unit when it is detected that the target baseband unit exists in each baseband unit 103.

[0044] In an embodiment, the switch can use RTL8370, and RTL8370 includes eight gigabit port physical layers (PHY, Port Physical Layer) and can provide eight Ethernet interfaces.

[0045] Please refer to Figure 2 , and the multi-modal communication base station further includes a 5G module 204, which is plugged into the communication interface 205 of the router 200.

[0046] In the embodiment, the 5G module 204 can be connected with the core network of the communication network in a wireless manner to realize wireless data transmission, and can provide a backup scheme for connecting with the core network when the WAN interface 202 cannot be connected with the core network, so as to ensure smooth connection with the core network.

[0047] In an embodiment, the communication interface 205 includes a USB interface or a serial port, and the 5G module 204 is connected with the router 200 through the USB interface or the serial port.

[0048] In this way, the 5G module is connected with the router in a pluggable manner. When the WAN interface cannot be connected with the core network, the router can flexibly connect the 5G module through the USB interface or the serial port, connect with the core network through the 5G module, and realize data transmission with the core network. The router drives the 5G module to work, and the 5G module adopts an independent module scheme. For example, the HM5000-32 module of TD-TECH adopts a standard M.2 interface, and can be used by being plugged in when needed.

[0049] It should be noted that generally, the multi-modal communication base station adopts a wired backhaul manner, that is, connected with the core network through the WAN interface. However, in special application occasions, Ethernet wiring cannot be performed, and at this time, a wireless backhaul manner needs to be used, that is, the 5G module is connected with the core network. The modular wireless backhaul manner improves the flexibility of system use and reduces the cost.

[0050] Please refer to Figure 2 , the router 200 further includes a WiFi module 203, and the WiFi module 203 is configured to be connected with the user terminal.

[0051] In the embodiment, the user terminal can be a mobile terminal such as a smart phone or a tablet computer.

[0052] In the embodiment, the WiFi module can provide a WiFi connection manner for the user terminal, and can also be used as a configuration management manner. When the operation and maintenance personnel need to maintain the multi-modal communication base station, it is not necessary to climb to the base station pole to perform serial port or network cable connection, but only needs to access the local area network inside the multi-modal communication base station through the WiFi manner under the base station pole, and enter the serial port of the corresponding baseband unit and controller through different local area network IP addresses to perform management operation.

[0053] In this way, the WAN interface and the LAN interface are isolated and managed through the router, and the WiFi wireless access is provided.

[0058] In this way, the three baseband units 103 have different frequency bands respectively. The first baseband unit 103 is a baseband unit for a mobile operator, and the corresponding frequency band is the frequency band possessed by the mobile operator. The second baseband unit 103 is a baseband unit for a telecom operator, and the corresponding frequency band is the frequency band possessed by the telecom operator. The third baseband unit 103 is a baseband unit for a Unicom operator, and the corresponding frequency band is the frequency band possessed by the Unicom operator. The controller 102 opens the three baseband units 103 according to the requirements of the upper management system of the communication network, so that each baseband unit 103 works in time according to the frequency band of the mobile operator, the frequency band of the telecom operator, and the frequency band of the Unicom operator, respectively, to realize the time-sharing operation of the three operators in different frequency bands, improve the integration of the communication base station, and reduce the deployment cost of the base station.

[0059] In this embodiment, the baseband units are not limited to those of three operators, but can also be those corresponding to four or five or more operators. The multiple baseband units can support multiple operators, and can be applied to various emergency communication sites. One multi-modal communication base station can replace multiple operator base stations, reduce deployment workload, and reduce equipment cost.

[0060] In addition, the three power supply interfaces 104 can supply power to other hardware monitoring devices to realize the integration of multiple hardware devices.

[0061] In an embodiment, the multi-modal communication base station further comprises a camera device, and the camera device is connected to a corresponding power supply interface.

[0062] In this way, the multi-modal communication base station can integrate the camera device and provide video monitoring function. The multi-modal communication base station provided in the embodiment can be installed on a highway to provide multi-modal communication function and video monitoring function, facilitate device expansion and on-site application deployment, and achieve the purpose of reducing deployment cost.

[0063] The multi-modal communication base station provided in the embodiment comprises multiple baseband units, and the multiple baseband units are connected to the master board, power amplifier, and other devices in a compact manner. Radio frequency columns are used to realize radio frequency interconnection, and connectors are used to realize power supply and signal interconnection, so as to avoid the problems of too many cables, disorder, and instability caused by cable connection, and reduce the size of the device. The multiple baseband units of the multi-modal communication base station provided in the embodiment can support multiple operators, and can be applied to various emergency communication sites. One multi-modal communication base station can replace multiple operator base stations, reduce deployment workload, and reduce equipment cost.

[0064] In addition, the multi-modal communication base station has a power supply interface, which can facilitate the access of other cameras and other devices, and can realize the isolation and management of WAN interface and LAN interface through the router, and can provide WiFi wireless access.
