Furthermore, each O-DU needs to be configured individually, requiring a large amount of human resources. When testing each O-RU, different items need to be tested one by one, resulting in low testing efficiency and a high error rate.

[0048] The present invention is described below based on embodiments, but the invention is not limited to these embodiments. In the detailed description of the invention below, certain specific details are described in detail. Those skilled in the art will fully understand the invention even without these details. To avoid obscuring the essence of the invention, well-known methods, processes, flows, elements, and circuits are not described in detail.

[0049] Furthermore, those skilled in the art should understand that the accompanying drawings provided herein are for illustrative purposes only and are not necessarily drawn to scale.

[0050] Unless the context explicitly requires it, words such as "including" or "contains" throughout the application should be interpreted as including rather than exclusive or exhaustive; that is, meaning "including but not limited to".

[0051] In the description disclosed in this invention, it should be understood that the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Furthermore, in the description disclosed in this invention, unless otherwise stated, "a plurality of" means two or more.

[0052] Typically, in existing technologies, signals are transmitted from an Open Distributed Unit (O-DU) to an Open Root Unit (O-RU) to test the O-RU's functionality and basic performance. The connection between the O-DU and the O-RU is based on the Open Radio Access Network (O-RAN) communication technology interface. Specifically, the O-DU and O-RU are connected via a front-haul interface, such as... Figure 1 As shown, the fronthaul interface is used to transmit four types of messages: management plane (M-plane), synchronization plane (S-plane), user plane (U-plane), and control plane (C-plane). The M-plane is a communication mode within the O-RAN. Assuming data transmission can use the Network Configuration Protocol (NETCONF), the M-plane is a collection of all NETCONF messages required by the O-RAN. Specifically, the M-plane is used to send and receive control messages for all management planes of the O-RU. Messages between the O-DU, the Network Management System (NMS), and the O-RU are mainly used for carrier establishment, software upgrades, status queries, antenna calibration, and electrically adjustable antennas. The O-DU interacts with other components of the O-RU. Figure 1 The specific structure is the same as or similar to that of conventional O-DU and O-RU, and will not be described in detail here.

[0053] The O-DU is required for functional verification of the O-RU, and adding an O-DU significantly increases the cost. When multiple O-RUs need to be tested, a corresponding number of O-DUs need to be configured, which is very costly. Furthermore, the configuration of the O-DU is very cumbersome, and the usage methods of O-DUs from different manufacturers are different. Therefore, each O-DU needs to be configured individually, which further increases the configuration and maintenance costs. When testing each O-RU, different items need to be tested one by one, resulting in low testing efficiency and a high error rate.

[0054] Therefore, how to quickly and accurately detect the O-RU while reducing costs and wasting human resources is a problem that needs to be solved.

[0055] In this embodiment of the invention, Figure 2 This is a simulator for detecting open radio frequency units according to an embodiment of the present invention. Figure 2 As shown, the simulator includes a Dynamic Host Configuration Protocol (DHCP) server 201, a Precision Time Protocol (PTP) server 202, a Secure File Transfer Protocol (SFTP) server 203, a Certificate Authority (CA) server 204, and at least one general interface 205.

[0056] Specifically, the DHCP server 201 is used to assign Internet Protocol (IP) addresses to the Open Radio Unit (O-RU); the PTP server 202 is used to send PTP messages to the O-RU via the network interface card (NIC) to synchronize the O-RU's clock; the SFTP server 203 is used to verify file upload or download functions; the CA server 204 is used to verify certificate-related functions; each of the general interfaces 205 is used to connect to at least one O-RU, wherein the simulator sends test data to the O-RU through the general interface to test the O-RU.

[0057] In one possible implementation, the DHCP server assigns an Internet Protocol (IP) address to the Open Radio Unit (O-RU). The IP addresses of the simulator and the O-RU can belong to the same network segment. Simultaneously, through a DHCP option, the O-RU obtains the IP address of the simulator, thereby triggering a connection initialization process, also known as a call home. If the simulator is not configured with the DHCP server, the user needs to manually configure the IP address for the O-RU and then connect through an active connect method. Compared to automatic configuration, this method wastes manpower and has lower accuracy.

[0058] In one possible implementation, the common interface 205 can be an RJ45 interface, and the simulator can be configured with multiple common interfaces, each interface connecting to one O-RU. Therefore, the simulator can simultaneously send test data to multiple O-RUs to verify and debug them.

[0059] In one possible implementation, the PTP server is also used to verify whether the O-RU is locked.

[0060] In one possible implementation, the CA server is used to verify certificate-related functions, specifically including: the CA server is used to verify certificate registration, certificate renewal, and certificate revocation.

[0061] In this embodiment of the invention, Figure 3 This invention relates to a system for detecting open radio frequency units, comprising a simulator 301 and at least one O-RU 302, wherein the simulator 301 is connected to the O-RU 302 via a common interface RJ45.

[0062] In one possible implementation, the Figure 3 When the simulator 301 and at least one O-RU 302 transmit data, they can use the network configuration protocol NETCONF or Secure Shell (SSH). The simulator can be a personal computer (PC) or a host computer. This embodiment of the invention does not limit the simulator.

[0063] In this embodiment of the invention, Figure 4 This is a simulator for detecting open radio frequency units according to an embodiment of the present invention. Figure 4 As shown, the simulator includes a Dynamic Host Configuration Protocol (DHCP) server 401, a Precision Time Protocol (PTP) server 402, a Secure File Transfer Protocol (SFTP) server 403, a Certificate Authority (CA) server 404, and at least one fiber optic interface 405.

[0064] Specifically, each of the fiber optic interfaces 405 is used to connect to at least one of the O-RUs, wherein the simulator sends test data to the O-RUs through the fiber optic interfaces to test the O-RUs.

[0065] In one possible implementation, the fiber optic interface 405 can be an Enhanced Common Public Radio Interface (ECPRI). The simulator can be configured with multiple fiber optic interfaces, each connected to an O-RU. Therefore, the simulator can simultaneously send test data to multiple O-RUs to verify and debug them.

[0066] In this embodiment of the invention, Figure 5 This invention provides a system for detecting open radio frequency units, comprising a simulator 501 and at least one O-RU 502, wherein the simulator 501 is connected to the O-RU 502 via an optical fiber interface. Figure 5 When the simulator 501 and at least one O-RU602 transmit data, they can use NETCONF or SSH. The simulator can be a PC or a host computer. This embodiment of the invention does not limit the specific type of simulator.

[0067] In this embodiment of the invention, Figure 6 This invention relates to a system for detecting open radio frequency units, comprising a simulator 601, at least one O-RU 602, and at least one switch 603, wherein the simulator 601 is connected to at least one switch via a common interface, and each switch is connected to at least one O-RU.

[0068] In this embodiment of the invention, Figure 7 This invention relates to a system for detecting open radio frequency units, comprising a simulator 701, at least one O-RU 702, and at least one switch 703, wherein the simulator 701 is connected to at least one switch via an optical fiber interface, and each switch is connected to at least one O-RU.

[0069] In this embodiment of the invention, Figure 8 This is a flowchart of a method for detecting an open radio frequency unit according to an embodiment of the present invention, which specifically includes the following steps:

[0070] Step S801: Determine the management plane M-plane test data for at least one open radio frequency unit (O-RU).

[0071] Specifically, the test data includes a single test case, multiple independent test cases, a single test group test case, multiple independent test group test cases, all test cases executed sequentially, and all test cases executed out of order.

[0072] In this embodiment of the invention, the test data is pre-stored in the simulator. Specifically, the test data can be passed in as a parameter or specified to be stored in a text file in the simulator. The test cases in the test data can be expanded or deleted, depending on the usage.

[0073] In one possible implementation, the selection of the single test case, the multiple independent test cross-cases, the single test group test case, the multiple independent test group cross-cases, the sequentially executed all test cases, or the unordered executed all test cases is based on the need to test the functionality of the O-RU.

[0074] Step S802: Send the test data to at least one O-RU for M-plane functional testing.

[0075] Specifically, the test data can be sent to multiple O-RUs simultaneously for M-plane function testing; or, the test data can be sent to multiple O-RUs in a time-sharing manner for M-plane function testing.

[0076] In one possible implementation, the following steps are included before step S801, specifically as follows: Figure 9 The above includes:

[0077] Step S803: Configure environment information.

[0078] Specifically, the environmental information includes at least one of the following: communication protocol, connection method, Internet Protocol IP address of the O-RU, port number of the O-RU, port number of the simulator, username, password, and certificate path.

[0079] In one possible implementation, the communication protocol includes SSH or TLS, the connection method includes Listen or Connect, and the IP address type can be IPv4 or IPv6. The emulator's port number and the certificate path are used for TLS as the communication protocol, and the username and password are used for SSH as the communication protocol.

[0080] In one possible implementation, the environment information can be specified or modified when the script is run by passing parameters; specifically, some of the environment information can be modified; or, the environment information can be modified by modifying a configuration file.

[0081] In this embodiment of the invention, the method includes: outputting a test log, wherein the test log includes multiple print levels.

[0082] Specifically, the test data is written into a script program. When the script program is run, the printing level of the test log can be set. The printing level includes sent, received, all, or result. Generally, the result is mainly used to record whether the test passed or failed.

[0083] In one possible implementation, other items that need to be set are also included, such as setting whether to continue when a test fails, setting to stop; setting the number of attempts when a test fails, setting to one; setting the number of loops, setting to one; setting the loop interval time, setting to one hour. These are just examples, and the specific settings should be based on the actual situation.

[0084] In this embodiment of the invention, from a data perspective, the data flow between the simulator and the O-RU is as follows: Figure 10As shown, the simulator comprises four parts: a main program, a complete set of functional tests, a configuration file, and an open-source library supporting the NETCONF network configuration protocol. The main program loads and parses the configuration file, identifies incoming parameters, establishes NETCONF-based and SSH-based session connections, sends messages based on dependencies and test rules, and judges returned messages. The main program is executed periodically or out of order as needed. The complete set of functional tests is designed for different products and different testing methods (e.g., positive and negative testing methods). During testing, the necessary test data is selected from the complete set. The configuration file contains two parts: basic configuration and test configuration. The basic configuration includes the communication protocol, connection method, the O-RU's Internet Protocol IP address, the O-RU's port number, the simulator's port number, username, password, and certificate path. The test configuration includes all independent functional test items that need to be tested. The configuration file can also be extended through an interface.

[0085] In one possible implementation, the Figure 10 In this process, the user layer ncclient or ssh sends the program to the physical layer (interface), and then the O-RU receives the test data through the physical layer (interface) to perform the test.

[0086] In this embodiment of the invention, the above-described testing method eliminates the need for an end-to-end testing environment when the O-RU performs Mplane testing, minimizing testing hardware costs and significantly reducing testing difficulty. Furthermore, it supports out-of-order testing, simulating user testing steps as closely as possible. It also supports multiple different operating modes, providing greater flexibility for testing. Moreover, being implemented using the Python programming language, it reduces portability costs and can be ported to self-verification development, continuous integration system verification, or release version verification, thus improving the flexibility of the O-RU testing.
