Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The network element access method provided by the invention can be used for solving the common platform management problem of network element access of a plurality of different communication protocols, realizes loose coupling of network element processing of the plurality of different communication protocols and a network management system logic component processing flow, and the network management system logic component only concerns how UDP transmission service parameter data is applied and presented, thereby having a clearer hierarchical mode for managing and controlling network element equipment such as a 5G macro base station, a 5G expanding station, a 5G splitting station, a Core network (Evolved Packet Core, EPC) and the like. The newly added communication protocol support only changes the communication component support of the communication gateway, and data planning information such as a database network element object model, a parameter model and the like, and stops the change of the service processing logic of the network management system caused by the change, thereby achieving the purpose of minimizing the change code range, further reducing the version iteration test and release verification investment, greatly reducing the development and maintenance cost of the network management system, further improving the management and control capability of the network management system on the network elements of a plurality of different communication protocols, and specifically realizing the following steps:

fig. 1 is a schematic flow chart of a network element access method provided by the present invention, and as shown in fig. 1, the method includes:

step 110, obtaining network element planning data, where the network element planning data includes one or more pre-planning network elements allowed to be accessed by each communication gateway;

and 120, accessing the M pre-planned network elements into N communication gateways based on the network element planning data, wherein each communication gateway communicates with the pre-planned network element allowed to be accessed by adopting different communication protocols, M is a positive integer, and N is less than or equal to M.

It should be noted that the execution subject of the method may be a computer device.

Alternatively, the network element access method provided by the present invention may be applied to an operation Maintenance and management Center (OMC) network management system shown in fig. 2.

As shown in fig. 2, the network management system includes a network management system logic component, a network management data center, a plurality of communication gateways, and a plurality of network element access areas. The network management data center mainly realizes the database service function, and the logic component of the network management system bears the data application presentation of network element state, configuration service, alarm service, performance service and the like. The communication gateway realizes the access management of a plurality of network elements, and particularly realizes the communication access interaction of the network elements of a plurality of different communication protocols at the downstream and the interaction with each logic component in the logic component of the upstream network management system.

The network management data center stores data of a service application layer, and the key relates to network element planning data accessed to network management. Before the implementation stage of network management engineering, the deployment plan of operator customers on network elements and the specific conditions of network element protocol parameters are combined, and the network element planning data can specifically comprise field data contents such as a parameter table-1, a service relation table-2, a network element table-3 and the like, which is an important basis for the unification of multi-protocol data processing and the balance of multi-protocol network element access control load. Particularly, the network element planning data is shared by the network management system logic component and the communication gateway, and in the initialization stage of the network management system logic component and the communication gateway, the planning information in the network element planning data can be acquired through the database interface, and the planning information specifically comprises one or more pre-planning network elements which are allowed to be accessed by each communication gateway.

Wherein, the "parameter table-1" includes but is not limited to the following field elements: 1. parameter ID,2, parameter name, 3, parameter object identifier OID path, 4, parameter data type, 5, parameter control type, 6, parameter length, 7, parameter value range, 8, parameter default value, 9, network element type ID to which the parameter belongs, 10 and service type ID. The specific service type is planned and made according to service classification and service division needs of a logic component of a network management system: such as: network element status messages, configuration messages, alarm information, health check data and the like are defined as different service type IDs, the service types are application differentiation and classification of network element service parameters, although the meaning of each network element service parameter is different, the service type differentiation is determined based on that the application is popular according to industry requirements, for example: configuration, alarm, performance, MR, SON applications, etc. Regardless of whether the interaction between the communication gateway and the access network element is SNMP protocol, TR069 protocol, or even other newly added proprietary protocols, etc., the communication gateway extracts and analyzes the data content of the characteristic characters of the 'parameter OID path' protocol carried by the corresponding protocol according to the support of the peer-to-peer network element protocol, and then maps and converts the data content into a 'parameter ID' data set corresponding to 'parameter table-1'.

The invention provides a network element access method, which relates to a deployment management service load balancing strategy of network elements of various different communication protocols, and is based on network management system logic processing load balancing, different UDP interactive ports are specified for different service types, and a registration relation between a network management system logic component and a communication gateway is planned, so that conditions are created for the network management system service logic processing data distribution, specifically, a corresponding relation between logic service and communication gateway service is planned and defined in a database and is marked as a service relation table-2, and the network element access method comprises but is not limited to the following field elements: 1. logic component ID,2, logic component name, 3, logic component IP address, 4, communication gateway ID,5, communication gateway IP address, 6, service type ID,7, UDP port number; wherein, 1 and 4 are running example numbers and respectively are mnemonics of the logic component and the communication gateway, and the mnemonics are accumulated in sequence from 1 to keep global uniqueness.

Determining which logic component should process frame data of a certain service type and different UDP ports intercepted by the logic component through the planning design of a service relation table-2; and on the other hand, the load balancing method for the network element access capability specifically combines the management capacity of the network elements of the existing network engineering to estimate and determine the number of the communication gateways. The communication gateway for dividing the network element access according to different administrative regions is a reference and is also convenient to manage, and the network elements deployed in the administrative regions are determined according to the size of the coverage area in principle, and of course, for a network management system, the network element access capability is essentially a cut of the network element access capability. Such as: the maximum access capability of 1 communication gateway is 5000, and assuming that 20000 network elements are in total, 4 communication gateways can be deployed for processing. In order to accurately control the load distribution of the network element access and the gateway, the corresponding relationship between the pre-planned network element and the communication gateway is marked as "network element table-3", which includes but is not limited to the following field elements: 1. network element device ID,2, network element device type ID,3, device number (serial number), 4, network element IP address, 5, network element access "communication gateway IP address". The network element management and control range of the network management system is established through the network element device object data expressed in the network element table-3, and the network element side needs to access according to the IP address of the communication gateway defined in the network element table-3.

A communication gateway is designed aiming at communication protocols corresponding to M pre-planned network elements (such as 5G network elements), and particularly relates to the conversion unification of network element multiprotocols to a single protocol. Specifically, communication protocols (TCP, SNMP, TR069 and the like) of different 5G network elements are converted into a self-defined UDP protocol to interact with an OMC network management system, the communication gateways realize different communication protocol mechanisms such as TCP, SNMP, TR069 and the like, one communication gateway is responsible for a corresponding network element area collection block and is respectively butted with network elements such as a 5G macro base station, a 5G micro base station, a 5G extended pico station and the like in the area collection block.

The communication gateway integrates the management support of communication protocols such as TCP, SNMP, TR069 and the like, so that the deployment and management of multiple gateways become simple and quick without considering the problems of diversity and differentiation of regional network elements. When a new type of pre-planned network element is added, only the communication management function of the communication gateway needs to be added, the protocol data conversion process is still unified, and the regular data content is changed by still combining the database model design.

And obtaining one or more pre-planning network elements allowed to be accessed by each communication gateway based on the obtained network element planning data, counting M pre-planning network elements allowed to be accessed by N communication gateways, and accessing the M pre-planning network elements to the N communication gateways.

The network element access method provided by the invention designs a plurality of communication gateways to buffer and decompose the access management pressure of the network elements of a plurality of different communication protocols, reduces the development and maintenance cost of a network management system, and improves the management and control capability of the network management system on the network elements of the plurality of different communication protocols.

Further, in an embodiment, the accessing, based on the network element planning data, the M pre-planned network elements to the N communication gateways may specifically include:

and according to one or more pre-planning network elements which are allowed to be accessed by each communication gateway, determining M pre-planning network elements which are allowed to be accessed by N communication gateways, and accessing the M pre-planning network elements to the N communication gateways.

Optionally, the following operations are performed for any one of the N communication gateways:

and obtaining a target network element identifier allowed to be accessed by each communication gateway based on the obtained network element planning data, wherein the target network element identifier may specifically include an equipment network element key identifier, an equipment number and an equipment serial number.

Different pre-planning network elements can access the same communication gateway, one or more pre-planning network elements with the same identification as the target network element are used as the pre-planning network elements accessing the communication gateway, and the one or more pre-planning network elements are accessed to the communication gateway.

And counting one or more pre-planning network elements corresponding to the target network element identification allowed to be accessed by each communication gateway, determining M pre-planning network elements corresponding to the target network element identifications allowed to be accessed by the N communication gateways, and accessing the M pre-planning network elements into the N communication gateways.

Further, in an embodiment, the network element identifier is obtained by:

Optionally, a network element parameter model is obtained, specifically, by obtaining data of a "parameter table-1" of a network management data center, the communication gateway does not care about display and presentation, specifically, only data of

fields

1, 3, 4, 6, 9 and 10 of the "parameter table-1" data are obtained, all parameter sets of the service type of the network element type are built and cached by taking the fields 9 and 10 as joint keywords, and a basic cushion is created for converting subsequent and upstream logic components into UDP messages. And constructing mapping parameter attribute rule information of the network element type protocol parameter path by using the fields 3 and 9 as the combined keywords, and providing an algorithm basis for protocol analysis conversion rules of subsequent and downstream network elements such as SNMP, TR069 and the like.

Receiving network element service parameters sent by a pre-planned network element according to a pre-planned network element peer-to-peer communication protocol, combining a parameter table-1, matching the received parameter information according to a parameter OID path, and performing reverse mapping to obtain a network element identifier (equipment network element key identifier, equipment number and equipment serial number) of the pre-planned network element, wherein the parameter information at least comprises the following data items: parameter identification, parameter name, parameter OID path, parameter data type, parameter control type, parameter length, parameter value range, parameter default value, network element type to which the parameter belongs, and service type.

The network element access method provided by the invention designs a plurality of communication gateway buffers to decompose the access management pressure of the network elements of a plurality of different communication protocols, reduces the development and maintenance cost of the network management system, and improves the maintenance processing capacity and efficiency of the network elements of a plurality of different communication protocols of the whole network management system.

Further, in an embodiment, after the accessing, to the N communication gateways, the M pre-planned network elements based on the network element planning data, the method may further specifically include:

Optionally, the communication gateway controls access to the pre-planned network element according to the network element planning data, converts parameter information of the pre-planned network element according to the network element parameter model, and reflects service data change of the pre-planned network element in an active push manner. The pre-planning network element access is controlled by the uniform planning network element equipment, and the data are constructed and put in storage through pre-planning and are uniformly shared by the communication gateway and the OMC network management system. The newly added network elements only relate to the adjustment of the database scripts and the business-independent changes of the communication gateway. The communication gateway can be used for independently deploying different networks, so that the data access safety is improved.

And combining the obtained network element planning data and the equipment serial number of the network element, searching the network element planning data by the communication gateway, and determining the network element equipment ID mapped by key identifications such as the equipment serial number, the IP address and the like. The pre-planned network element incorporated into the network management system through the network element table-3 has a network element equipment ID for identifying the identity of the network element no matter what communication protocol is used, and the network element equipment ID is known in the whole network management system and is a uniform expression of each service level of the network management system to a network element object.

Further, in an embodiment, the acquiring a network element service parameter dataset corresponding to parameter information of one or more pre-planned network elements accessing the communication gateway includes:

converting parameter information of one or more pre-planned network elements accessed to the communication gateway based on a parameter model, updating the parameter information according to the network element type and the service type of the pre-planned network elements, and generating a network element service parameter data set;

And if the planned network element equipment ID cannot be mapped, the network element equipment ID indicates an illegal network element, the access is rejected. And if not, continuing to convert the parameter information reported by the pre-planned network element according to a conversion rule of the parameter information of the pre-planned network element in the parameter model, and collecting and updating the relevant parameter information according to the type of the network element and the type of the service.

The key of the parameter model comprises rule information (marked as a parameter table-1) of network element service parameters, which is a unified parameter model designed aiming at the service data of the 5G multi-network element, and particularly relates to the abstraction unification of a network element service data management interface. Specifically, a unified parameter model of the network element is established by objectifying, parameterizing and abstracting the data representation design of the network element of the service data of different 5G network elements (such as a 5G expanding station, a 5G splitting station, a 5G macro base station and the like). The method specifically comprises equipment object data, alarm, configuration and other business parameter model rule data.

The communication gateway continuously updates parameter ID set data, such as presence, configuration information, alarm data, health check data, of the network elements holding the respective communication protocols. The communication gateway caches the data structure as map object data, takes the network element type ID and the service type ID as joint index keywords, and gathers data sets with the target of multi-parameter ID and parameter value pairs, namely network element service parameter data sets.

And encapsulating the network element service parameter data set based on a UDP protocol to obtain a UDP message, and transmitting the UDP message to a target logic component in the network management system logic component through a communication gateway.

Based on the parameter table-1 information of the parameter model rule, the information is converted into a user-defined UDP protocol format, based on the data of a service relation table-2, a target IP address and a UDP port which are actively reported are determined, when the network management service logic is started, the network management service logic monitors and receives corresponding UDP port data respectively according to the difference of logic components without mutual interference, the load pressure decomposition and the high-efficiency application of multi-network-element service data processing are achieved, and the multi-network-element access management processing efficiency is finally improved.

On one hand, the communication gateway not only communicates with downstream network elements in a popular way, but also particularly relates to the change of the interaction mode with the logic component of an upstream network management system, and particularly actively pushes data in a determined UDP protocol frame format. Specifically, the method comprises the following steps: the communication gateway reserves network element data of a plurality of different communication protocols, is designed by depending on a network element parameter model, parameterizes the data reported by the network element instead of a popular service structure body, and particularly mainly takes two items of 'equipment ID' and 'service type ID' as topic content keywords to collect and store a corresponding service protocol parameter list. Because the parameter structure is universal and uniform, and the list is telescopic, the change of the network element service can not influence the change of the upstream network element service data processing interface; on the other hand, the communication gateway monitors the change of the network element service data, such as the change of the online state, the change of the configuration parameters, the report and update of the alarm, and the deterioration of the health index, and actively pushes the logic component to process when the change occurs.

The communication gateway adopts a user-defined user datagram protocol UDP to interact with the logic component of the upstream network management system, and has the advantages of low technical integration dependence and large interventionalisable space. The method makes full use of the characteristic of high efficiency of UDP connectionless transmission, flexibly organizes data, and has the capability of reporting one or more network element service data once or for many times according to the size of the data. The UDP protocol format is characterized by: the first is a transport message control header part, which includes but is not limited to: 1. sync byte, 2, data length, 3, service type ID,4, serial number, 5, reply flag. Wherein

items

1 and 2 are used for carrying data content integrity control in UDP transmission. Item 3 expresses the type of service to which the parameter belongs, for the communications gateway, to distinguish the categorical set of service parameters, for the upstream service components, is the key distinction in the representation of the service application. The message serial number and the response mark expressed in items 4 and 5 are used for service transmission control, and for the data requiring to confirm the serial response, if the corresponding serial response is not received, retransmission control is performed. The second is a multi-network element service data content part, which includes but is not limited to: 1. network element type ID,2, equipment ID,3, parameter ID,4, parameter value. From the design of UDP protocol, the network element object and the parameter object are expressed by adopting the generic ID, and the method has very strong expansion adaptability. The user-defined UDP data is cut according to the network element types, only the network element data of the same type is reported at one time, and the user-defined UDP data still has the capability of sending a plurality of network element object data in batch at one time. The upstream logic component realizes different service support according to the network element type and the data service type, such as updating the online state of the network element, the alarm state, the configuration data, the health index data and the like.

A logic component: the service modules of configuration, alarm, performance and the like and the communication gateway adopt UDP protocol interaction, realize the unification of multi-communication protocol network element data processing, and are characterized in that: the method comprises the steps of arranging service parameters of various network elements such as a 5G macro base station, a 5G micro base station, a 5G extended pico station and core network equipment, predefining equipment type IDs of access network elements, and combining with specific equipment service parameter support, and pre-constructing various network element type parameter set models.

For example, as shown in fig. 3, the UDP frame format design is specifically applied to data interaction between a communication gateway and a logic component in a network management system. The UDP message consists of two parts, specifically, a transmission control message header and device service parameter data content.

The transmission control message head is composed of 5 components of synchronous byte, message length, service type ID number, serial ID number and response mark. The network element service parameter part expresses a plurality of network element data of the same type by network element types and network element numbers, and expresses a plurality of service parameter sets by parameter numbers, parameter IDs, parameter lengths and parameter values. The UDP protocol design considers the transmission efficiency and supports batch transmission of a plurality of parameter data of a plurality of network elements at one time.

In addition, in consideration of serial number generation efficiency, a decentralization strategy is adopted, and a data generation method is designed for who claims to generate the data, and specifically the data generation method is used for local service generation of a data request initiating party. Such as: if the logic component initiates a data query synchronization request to the communication gateway, the logic component generates the data query synchronization request; and if the communication gateway actively reports the service parameters to the logic component, the service parameters are generated by the communication gateway. In addition, in view of reverse readability, the serial number ID (marked as Q) abandons the popular UUID random number method, and specifically comprises three elements: 1. running service instance number (marked as S, occupying the front 2 bytes), 2, current running time millisecond number (marked as T, occupying the middle 4 bytes), 3, running thread sequence number (marked as R, occupying the tail 2 bytes), namely, an 8-byte integer to express distinction, and the generation algorithm is as follows: q = (S < < 48) + (T < < 16) + (R &0 xFFFF), inverse parsing algorithm: s = (Q > > 48), T = (Q > > 16), R = (Q &0 xFFFF), wherein when the serial number ID is generated, S is planned and determined by

fields

1 and 4 in the service relation table-2, and S solves the problem of the possibility of repeated T and R conflicts among multiple services; t and R are determined by service runtime resources, and the T and R solve the problem of the possibility of multithreading concurrent repeated conflict.

Further, in an embodiment, transmitting the UDP packet to a target logic component in a network management system logic component through the communication gateway may specifically include:

Optionally, based on the obtained network element service parameter data set, the communication gateway reports to a target logic component in the network management system logic component in a self-defined UDP protocol packet in two modes of periodicity and change reporting according to service characteristics. In a specific implementation aspect, by using an association relationship established by fields 6 and 7 in a service relationship table-2, a communication gateway determines a port for transmitting a UDP packet according to a service frame type identifier (including a service type of the pre-planned network element) of a UDP packet to be reported; and acquiring the IP address of the logic component corresponding to the registration by the communication gateway according to the IP address of the communication gateway by utilizing the incidence relation of the fields 3 and 5 in the service relation table-2, thereby determining the target logic component IP to be transmitted by the UDP message. Therefore, a UDP message can be accurately pushed to a target logic component for processing.

And the target logic component receives the UDP message reported by the communication gateway, receives the UDP message at which UDP port, and similarly, based on the data of the service relation table-2, and when the target logic component initializes, such as configuration, alarm, performance service and the like, acquires the associated UDP port set according to the IP address of the target logic component, and starts different UDP receiving threads to process the UDP message transmitted by the corresponding UDP port. And finally, performing corresponding service processing according to the service frame type identifier carried by the user-defined UDP message, such as: and storing the online state of the equipment, the alarm service data and the like and presenting the information by a push front end.

Fig. 4 is a second flowchart of the network element access method provided in the present invention, and as shown in fig. 4, in other embodiments of the present invention, a process of processing reported data accessed by network elements such as a baseband processing unit BBU, a nano base station nancel, a core network EPC, and a customer premises equipment CPE specifically includes:

step 410, network element planning data and a network element parameter model are obtained when the communication gateway service is initialized. In the aspect of network element planning data, SQL query interfaces are executed to obtain data of a network element table-3 of a network management data center, wherein the table is searched by taking the gateway IP of a communication gateway as a keyword, so that the aim of only collecting a network element set controlled by the communication gateway is fulfilled, and through the process, the communication gateway defines the range of network element objects allowed to be accessed; in the aspect of a network element parameter model, data of a 'parameter table-1' of a network management data center is acquired specifically, a communication gateway does not care about display and presentation, specifically, only data of

fields

1, 3, 4, 6, 9 and 10 in the 'parameter table-1' are acquired, all parameter sets of network element types and service types are constructed and cached by taking the fields 9 and 10 in the 'parameter table-1' as joint keywords, and a basic cushion is created for converting subsequent and upstream logic components into UDP protocol parameters. And (3) constructing mapping parameter attribute rule information of a network element type protocol parameter path by taking fields 3 and 9 in a parameter table-1 as joint keywords, and providing an algorithm basis for analyzing and converting rules of subsequent communication protocols such as SNMP (simple network management protocol) and TR069 of downstream network elements.

Step 420, sending access request data by network element equipment such as an EPC/BBU/NANOCELL/and the like; the communication gateway integrates communication management support such as SNMP protocol, TR069 protocol and the like, so that the deployment and management of multiple gateways become simple and rapid without considering the problems of diversity and differentiation of regional network elements. When a new type of network element is added, only the communication management function of the 5G communication gateway is added, the protocol data conversion process is still unified, and the data content of the rule is changed by combining the design of the database model. When network elements such as EPC, BBU, NANOCELL and the like in a network element area group send access request data, the communication gateway monitors related network element access request data, and each type of network element needs to carry manufacturer OUI, equipment model and equipment serial number for representing the identity of the network element according to the requirement of a network element access protocol; if the fixed IP access is not carried, the IP address of the access network element can be obtained from the communication layer to be used as the network element distinguishing identification.

Step 430, in combination with step 420, the communication gateway receives the network element access information data according to the network element peer-to-peer communication protocol, and performs reverse mapping to obtain the network element identifier, including the network element key identifier, the device number, and the device serial number, by using the parameter model data obtained in step 410 and the parameter information received according to the parameter OID path matching.

Step 440, combining the network element planning data obtained in step 410, the network element device serial number obtained in step 430, and the communication gateway searches the network element planning data, and determines the device ID of the network element mapped by the key identifier, such as the network element device serial number, the IP address, etc. By planning the 'net element table-3' in the early stage, the net element incorporated into the network management system has an equipment ID for marking the net element identity no matter what kind of protocol net element, and the network management system is well known and is a unified expression of each service level of the network management system to the net element object.

Step 450, in combination with step 440, the process of finding the planned cache by the communication gateway is the validity verification process of the network element access network element, and if the device ID of the planned network element cannot be mapped, which indicates that the network element is an illegal network element, the access is rejected. Otherwise, the parameter information reported by the network element is continuously converted according to the conversion rule in the parameter model obtained in step 410, and the relevant parameters are updated according to the collection of the network element type and the service type.

Step 460, in conjunction with step 450, the communication gateway continuously updates and maintains the parameter ID set data of the network elements of each type of protocol, such as online status, configuration information, alarm data, and health check data. The communication gateway caches data structure as map object data, takes the network element type ID and the service type ID as joint index keywords, and gathers data sets with multi-parameter ID and parameter value pairs as targets.

Step 470, based on the data set formed in step 460, the communication gateway reports to the logic component in two ways, namely, periodically and variably reporting according to the service characteristics, by using the user-defined UDP packet. In the specific implementation aspect, the network management communication gateway determines a UDP port for transmission according to the service frame type identifier to be reported by using the association relationship established by the fields 6 and 7 in the service relationship table-2; and by utilizing the incidence relation of the fields 3 and 5 in the service relation table-2, the communication gateway acquires and registers the corresponding logic component IP according to the self IP, thereby determining the target logic component IP to be transmitted. Therefore, one UDP message can be accurately pushed to a network management target service component for processing.

Step 480, in combination with step 470, the target logic component processes the parameter data and stores the library and pushes the front end to present according to the reported service differentiation message ID; the target logic component receives the UDP message reported by the communication gateway, and as for which UDP port to receive, based on the data of the service relation table-2, when the network management service logic component initializes, such as configuration, alarm, performance service and the like, the network management service logic component acquires the related UDP port complete set according to the IP of the service component, and starts different UDP receiving threads to process corresponding port data. And finally, performing corresponding service processing according to the service frame type identifier carried by the user-defined UDP protocol, such as: and storing the online state of the equipment, the alarm service data and the like and presenting the online state, the alarm service data and the like by a push front end.

The network element access method provided by the invention has the advantages that base station equipment such as CPE, NANOCELL and the like are accessed into different communication gateways according to the area planning, the communication gateways interact according to protocols such as SNMP/TR069 and the like which are equivalent to network element communication, the key is that the design is converted into a generalized parameter set according to a unified parameter model rule, conditions are created for abstracting and unifying a processing interface of a logic component of a network management system, and the purpose that once the design is finished, the design is not changed is achieved. In addition, the communication gateway of the network management system shields the communication protocol difference of SNMP/TR069 and the like to the upstream component, and designs a plurality of communication gateway buffers to decompose the network element communication access management pressure of a plurality of different communication protocols, thereby improving the maintenance processing capacity and efficiency of the whole network management system to the network element.

Compared with the prior art, when the invention relates to the access of various different types of 5G network elements and the access of a large number of network elements of the same type, the invention only interacts with the communication gateway component, when the access control of a new type of network elements is added, the communication gateway independently adjusts adaptation, but ensures the uniform format of output UDP protocol data, thereby ensuring that the mode of network element service data in an OMC network management system is not changed. Through the conversion processing of the communication gateway service parameters, the network management logic service focuses on the service parameter application, and the communication gateway only generates a parameter protocol list of related services according to the parameter model rule without focusing on the parameter application. The problems of confusion of multi-communication protocol network element data processing levels and high service data processing logic coupling degree of the original network management system are solved. The network management system has larger flexible space in the multi-protocol network element access management, and finally, the manpower and material resources are saved, and the multi-protocol network element access control efficiency of the network management system is improved.

The network element access method provided by the invention overcomes the problems of high design coupling and low system efficiency of the network management system caused by the network element management of a large number of different communication protocols, and improves the delivery capacity and operation and maintenance efficiency of the network management system.
