[0019] It should be noted that, in the absence of conflict, the embodiments in the present application and the features in the embodiments may be combined with each other. The present utility model is further described in detail below in conjunction with the drawings and specific embodiments.

[0020] In the embodiments of the present invention, if there are directional indications (such as up, down, left, right, front, back, etc.), they are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0021] In addition, in the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0022] Please refer to Figures 1 to 8The cloud base station based on the S5000 controller of the embodiment of the utility model includes an S5000 controller, a storage module, a memory module, a TCM module, a BMC module, an M.2 connector, a communication module, an RDI MM interface, a UART / 12C / PCI interface, a PCIe interface, a 5G / 4G unit, and an FPGA.

[0023] The S5000 controller is electrically connected to the storage module and TCM module through the M.2 connector, the S5000 controller is electrically connected to the memory module through the RDIMM interface, the S5000 controller is electrically connected to the BMC module through the UART / 12C / PCI interface, and the S5000 controller is electrically connected to the communication module, 5G / 4G unit, and FPGA through the PCIe interface. The storage module can use SSD, and the memory module can use DDRS-ECC.

[0024] The S5000 controller implements the functions of the 4G protocol stack and the 5G protocol stack. The 5G / 4G unit includes PC802 (4G and 5G), which implements physical layer functions such as CRC scrambling, layer mapping, encoding and decoding, and channel measurement. The FPGA converts the physical layer digital information into ecpri information, and the domestic RRU completes the dual-mode wireless signal transmission and reception.

[0025] The S5000 controller uses a cloud-based deployment protocol stack. The 4G protocol stack is implemented through the eNB pod, including containers OAMcontainer, RRC container, and Mac container. The 5G protocol stack is implemented through the gNB pod, including containers OAMcontainer, CU container, and DU container. Cloud-based intelligent cell management dynamically detects the number of cell users and the use of cell hardware resources, dynamically increases and decreases cells, and reallocates hardware resources. PC802 5G supports up to 4 cells, and PC802 4G supports up to 3 cells, which can be dynamically scaled according to cloud-based cell management.

[0026] The S5000 controller can use the Kubernetes cluster platform and the platform's own network virtualization technology to achieve efficient data transmission between services, Pods, and containers.

[0027] The working principle of container architecture layering is as follows Figure 3 As shown, from bottom to top they are:

[0028] Operating system: openEuler operating system.

[0029] Kubernetes + Docker platform: Docker is a common container implementation method. Kubernetes is responsible for orchestrating Docker and provides a series of service startup, scheduling, monitoring, and container recycling functions to ensure that containers can run healthily. It includes a series of service software, such as apiserver, scheduler, and ontrollermanage.

[0030] Image layer: Container operation requires container images, which can be nested. The bottom layer is the basic image, such as the operating system basic image. Business images and platform images can then be built based on the basic image. In addition, system orchestration needs to rely on some third-party basic service images.

[0031] Container layer: The image is deployed and run through Kubernetes, and the container runs according to the business division. It can also be called pod under Kubernetes. In addition to the business container, there are also containers for basic services and platforms.

[0032] Service layer: presents the services provided by the business to the outside world. Only the containers on the business side will be presented as services, which is also where the ultimate value is reflected.

[0033] Network virtualization: In a kubernetes cluster, a complete network mechanism is provided within the cluster, including automatic allocation of podip, automatic allocation of service ip, creation of routing rules between nodes, exposure of external ip, etc. The network of the entire cluster is completely virtualized, and the services in the pod do not need to care about their own pod addresses, the ip of the interactive service, or the ip address of the node.

[0034] PCIe interfaces include PCIe*4, PCI3, PCIe4*2, PCIe*8, PCIe*16, etc. For example, PC802 5G is connected to the S5000 controller via PCIe*16 gold finger, PC802 4G is connected to the S5000 controller via PCIe*16 gold finger, and PC802 5G is connected to FPGA via 204B*4, PC802 4G is connected to FPGA via 204B*4, and FPGA is connected to domestic RRU via SFP28*4.

[0035] The BMC module can monitor the physical status of hardware devices (such as temperature, humidity, voltage, current, fan speed, etc.) by calling sensors, and communicate with the system management machine through an independent connection, so that a single system management machine can remotely manage and monitor multiple computers and servers in batches, perform event alarms, log recording and processing, and control heat dissipation, thereby realizing functions such as server hardware status management, health status management, power consumption management, power supply management, and fault alarms.

[0036] As an implementation method, the communication module includes a WX1820 network card, a WX1890 network card, an optical port, and an electrical port. The S5000 controller is electrically connected to the WX1820 network card and the WX1890 network card through a PCIe interface, and the WX1820 network card and the WX1890 network card are electrically connected to the optical port and the electrical port, respectively. Optical port: A general term for various optical fiber ports in servers and networks, which use light as the carrier medium for information. The optical port uses optical fiber for data transmission, and the optical fiber interface is a physical interface for connecting optical fiber cables. The optical port includes various optical fiber interfaces from ST to SFF (miniaturized optical fiber connector, mainly MTRJ and LC), and common types include MTRJ, LC, SC, FC, etc. Electrical port: A general term for various twisted pair interfaces such as RJ45 in servers and networks, all of which use electricity as the carrier medium for information. The electrical port uses copper cables (such as ordinary network cables and RF coaxial cables) for data transmission. The electrical port mainly uses RJ45 connectors.

[0037] As an implementation method, the cloud base station based on the S5000 controller further includes a PCIE slot, and the S5000 controller is electrically connected to the PCIE slot via a PCIe interface. The PCIE slot includes a PCIE*8 slot, a PCIE*16 slot, and the like.

[0038] As an implementation mode, the cloud base station based on the S5000 controller also includes a USB expansion chip, and the S5000 controller is electrically connected to the USB expansion chip via a PCIe interface.

[0039] As an implementation mode, the cloud base station based on the S5000 controller also includes a test serial port, and the S5000 controller is electrically connected to the test serial port.
