[0033] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0034] Referring to Figure 1 , Figure 1 is a flow chart of a PM file generation method provided by an embodiment of the present application. The PM file generation method comprises the following steps.

[0035] S1, when detecting that a PM performance measurement function is started, receiving PM data packets sent by at least one network element;

[0036] S2, identifying the PM data packets;

[0037] S3, integrating PM data packets belonging to a same network element identifier and a same PM task number to generate a PM file.

[0038] It is worth noting that the embodiment of the present application is implemented by an OM (Operations and Maintenance) management system arranged at a gNB base station side. Referring to Figure 2 , Figure 2Figure 1 is a schematic diagram of information interaction between a network management device and a gNB base station provided by an embodiment of the present application. When the network management device starts a PM measurement task, the network management device sends a PM configuration task to the gNB base station, and requests the OM management system of the gNB base station to report a PM file to the network management device. The PM file can be used for network evaluation and system operation and maintenance after being acquired by the network management device. The PM file is mainly used for evaluation of UE access to the gNB base station and evaluation of gNB base station performance, and is mainly divided into cell-level PM parameters, DU (Distributed Unit)-related PM parameters, CU (Centralized Unit)-related PM parameters, and statistics of hand-in and hand-out and inter-system hand-in and hand-out related PM parameters. The CU and DU related PM parameters are further distinguished by PLMN (Public Land Mobile Network) for statistics, and individual parameters are further distinguished by 5QI (5G QoS Identifier) for statistics, slice statistics, and the like.

[0039] The PM configuration task sent by the network management device defines a PM file upload period and an upload enable switch. The PM file upload period represents a period for the gNB to generate the PM file, and the period should be 15 minutes and an integer multiple of 15 minutes. The PM file upload enable switch is used to turn on and off PM performance measurement. For example, 0 indicates that the gNB base station turns off the PM performance measurement, and 1 indicates that the gNB base station turns on the PM performance measurement function. For example, when the PM upload enable switch of the gNB is turned on and the upload period is configured as 15 minutes, the OM management system acquires PM parameters from each network element every 15 minutes. The OM management system collects the PM parameters and generates a PM file in association, and reports the PM file to the network management device.

[0040] The PM file generation method in the embodiment of the present application is applied to a PM measurement process in a distributed deployment scenario. Referring to Figure 2, Figure 3 , Figure 3Figure 1 is a schematic diagram of a distributed deployment scenario provided by an embodiment of the present application, and PM data is derived from a DU server and a CU server, and the DU and CU server can be one or more. In a 5G RAN (Radio Access Network) architecture, the 5G base station BBU (Base Band Unit) function is restructured into two functional entities, CU and DU. The DU is a distributed unit responsible for processing real-time, and the CU is a central unit responsible for processing non-real-time, RRC, PDCP, and other high-layer protocols. The CU server can be further divided into CUUP (gNB-CU-User Plane) and CUCP (gNB-CU-Control Plane), and PM data is derived from multiple sources and is chaotic. For example, the DU server and the CU server can both perform PM measurement task 1 and PM measurement task 2 (PM measurement tasks are created by network management equipment notification). After the PM data of the service-side network element (the network element type can be DU or CU) is sent to the OM management system after being unpacked, the abnormal PM data is recombined via the configuration strategy processing unit of the CU and the DU, and finally the normal PM file is generated.

[0041] Specifically, in step S1, each of the network elements generates the PM data packet according to a preset configuration strategy, and the configuration strategy defines the encapsulation message structure of the PM data packet. Referring to Figure 2, Figure 4 , Figure 4 Figure 3 is an encapsulation structure diagram of a PM data packet provided by an embodiment of the present application. The encapsulation message structure includes a general data packet header, a special data packet header, and a message body. The general data packet header records the source of the data block (whether the PM data packet is derived from the CU or the DU), and the special data packet header records the PM task number and the network element identifier of the data block.

[0042] Further, the general data packet header also records PM measurement related parameters and the total packet length. The PM measurement related parameters include cell-level PM parameters, DU-related PM parameters, CU-related PM parameters, and PM parameters related to hand-in and hand-out and inter-system hand-in and hand-out. The special data packet header also records unpacking information and a check number. The unpacking information includes the unpacking number (i.e., the complete data belonging to the same PM task and network element is split into several PM data packets), the sequence number of the current packet, and the message length of a single data packet.

[0043] Specifically, in step S2, the PM data packet is identified, including: identifying the PM task number of the PM data packet according to the first flag bit of the PM data packet; and identifying the network element identifier of the PM data packet according to the second flag bit of the PM data packet.

[0044] Exemplarily, the first flag bit and the second flag bit are both located in the special data packet header. For example, when the PM test task 2 is started in the distributed deployment scenario, the OM side receives the PM data packets reported by the CU server and the DU server, and when the first PM data packet arrives at the OM side, the OM side first determines which PM task according to the PM task number recorded in the first flag bit of the PM data packet, and then determines which network element sends the data according to the network element identifier recorded in the second flag bit of the PM data packet.

[0045] Specifically, in step S3, after the PM data packet is identified, the PM data packets belonging to the same network element and the same PM task can be integrated according to the PM task number, the network element identifier and the unpacking information, and a PM file is generated.

[0046] In the embodiment of the present application, the network element performs packet assembling according to the configuration strategy before sending the PM data packet, so that the management system of the base station side can effectively collect the PM data when receiving the PM data packet, and can accurately distinguish the PM data packets from different sources, and integrate the PM data packets with the same network element identifier and the same PM task number, thereby improving the accuracy of the generated PM file while normally generating the PM file.

[0047] Further, in the distributed deployment scenario, there are multiple service network elements periodically sending data to the PM processing module, and the server time of each server cannot be synchronized, so that the data of each network element cannot be reported at the same time, and the sending sequence of the network element data is chaotic, thereby causing the generated PM file to be inaccurate, or even unable to normally generate the PM file. In order to further solve this technical problem, the embodiment of the present application can also synchronize the network element time, so that the data of different network elements can be reported at the same time, and the sending sequence of the network element data is avoided to be chaotic.

[0048] Specifically, when the PM performance measurement function is detected to be started, the method further includes: acquiring the deployment state of the network element; when the network element and the current management system are deployed on the same server, synchronizing the time of the network element deployed on the same server based on the time of the current management system; and when the network element and the current management system are deployed on different servers, enabling a network terminal protocol client to synchronize the time of the network element deployed on different servers.

[0049] Exemplarily, referring to Figure 5 , Figure 5The embodiment of the present application provides a network element time synchronization flowchart, in order to ensure that the time of each server cannot be synchronized, the NTP (Network Time Protocol) synchronization technology is adopted to improve the problem, and it is ensured that there is only a very short time error when multiple servers report data. First, the type of the network element is judged to be CU or DU, and the CU flow is further elaborated, when the type of the network element is CU, the CU deployment state is further judged, that is, whether the CU and the OM management system are deployed on the same server; when the CU deployment state is CU / OM separation, the NTP client is enabled to perform time synchronization on the multiple servers collecting PM data, so that the multiple servers report PM data at almost the same time; when the CU deployment state is not CU / OM separation, the CU / OM is on the same server, and the NTP synchronization of multiple PM test tasks is performed with the OM management system as a reference.

[0050] Further, after receiving the PM data packet sent by at least one network element, the method further comprises: checking the PM data packet.

[0051] For example, the check number recorded in the special data packet header is a CRC check number, and the process of checking the PM data packet by using the CRC check number can refer to the prior art, which will not be described here.

[0052] Compared with the prior art, the PM file generation method disclosed by the present application, when the PM performance measurement function is detected to be started, the management system on the base station side receives the PM data packet sent by at least one network element; wherein each network element generates the PM data packet according to a preset configuration strategy; the PM data packet is identified; the PM data packets belonging to the same network element identifier and the same PM task number are integrated to generate a PM file. When the PM measurement is deployed in a distributed deployment scene, the network element performs packet assembly according to the configuration strategy in advance when sending the PM data packet, so that no matter whether the business network element data sending sequence is chaotic or the business measurement has a large number of network elements and PM task numbers, the management system on the base station side can accurately distinguish the PM data packets from different sources when receiving the PM data packet, and integrate the PM data packets from the same network element identifier and the same PM task number, so as to normally generate the PM file and improve the accuracy of the generated PM file. In addition, the network element time is synchronized, so that the data of different network elements can be reported at the same time, and the chaotic network element data sending sequence is avoided.

[0053] Referring to Figure 6 , Figure 6 The embodiment of the present application provides a structure block diagram of a PM file generation device 100, the PM file generation device 100 comprises:

[0054] The data receiving module 11 is configured to receive the PM data packets sent by at least one network element when the PM performance measurement function is detected to be started, wherein each network element generates the PM data packets according to a preset configuration strategy.

[0055] The PM processing module 12 is configured to identify the PM data packets and integrate the PM data packets belonging to the same network element identifier and the same PM task number to generate a PM file.

[0056] It is worth noting that the PM file generation device 100 described in the embodiment of the present application is an OM (Operations and Maintenance) management system arranged on the gNB base station side.

[0057] Specifically, the configuration strategy defines the encapsulation message structure of the PM data packets, and the encapsulation message structure includes a general data packet header, a special data packet header and a message body; wherein the general data packet header records the source of the data block, and the special data packet header records the PM task number and the network element identifier of the data block.

[0058] Specifically, the general data packet header also records the PM measurement related parameters and the total packet length, and the special data packet header also records the unpacking information and the check number.

[0059] Specifically, the PM processing module 12 is configured to identify the PM task number of the PM data packet according to the first flag bit of the PM data packet, and identify the network element identifier of the PM data packet according to the second flag bit of the PM data packet.

[0060] Specifically, the PM file generation device 100 further includes a time synchronization module, which is configured to: when the PM performance measurement function is detected to be started, acquire the deployment state of the network element; when the network element and the current management system are deployed on the same server, perform time synchronization on the network element deployed on the same server based on the time of the current management system; and when the network element and the current management system are deployed on different servers, enable a network terminal protocol client to perform time synchronization on the network element deployed on different servers.

[0061] Specifically, the PM processing module 12 is further configured to: after receiving the PM data packets sent by at least one network element, perform a check on the PM data packets.

[0062] It is worth noting that the working process of each module in the PM file generation device 100 described in the embodiment of the present application can refer to the working process of the PM file generation method described in the above embodiment, and will not be repeated here.

[0063] Compared with the prior art, the PM file generation device 100 disclosed by the application detects that the PM performance measurement function is turned on, and the PM file generation device 100 on the base station side receives PM data packets sent by at least one network element; wherein each network element generates the PM data packet according to a preset configuration strategy; the PM data packet is identified; and the PM data packets belonging to the same network element identifier and the same PM task number are integrated to generate a PM file. When the PM measurement is deployed in a distributed deployment scenario, the network element performs packet grouping according to the configuration strategy in advance when sending the PM data packet, so that no matter whether the business network element data sending sequence is chaotic or the business measurement has a large number of network elements and PM task numbers, the PM file generation device 100 on the base station side can accurately distinguish the PM data packets of different sources when receiving the PM data packet, and integrate the PM data packets of the same network element identifier and the same PM task number, so as to normally generate the PM file and improve the accuracy of the generated PM file. In addition, the network element time is synchronized, so that the data of different network elements can be reported at the same time, and the chaotic network element data sending sequence is avoided.
