Description

A dynamic adaptive intelligent network management system and its implementation method

technical field

The invention relates to the technical realization of an intelligent network management system in the telecommunication industry, and can also be applied to other telecommunication equipment network management systems. It is a layered structure of network management data supply layer, network management data reporting layer, network management data collection and display layer, and is a technology to realize the dynamic change of intelligent network value-added services and network management indicators for dynamic reporting, collection and display.

Background technique

Intelligent network is an architecture used to generate and provide telecommunication services. Its most important feature is to provide various special value-added services quickly, conveniently, flexibly and economically. As telecom operators pay more and more attention to network operation quality and economic benefits, the construction of network management becomes more and more important, and the intelligent network management system is produced under this requirement.

The current telecommunication equipment network management system, such as switches, MSC, etc., has basically fixed network management indicators. The implementation method of network management is that the data supply layer and the network management data reporting layer are not separated. For the data reported by the network management, the specific field name indicates the specific index meaning. The switch group traffic statistics network management datagram is shown in the following table:

serial number Field Name - English Chinese name Field Type 1 Centrexid Centrex group logo INTEGER 2 Callout Exhaled times INTEGER 3 Callin Number of incoming calls INTEGER 4 internal Number of internal calls INTEGER 5 Outserl Outgoing traffic volume (outgoing time/period) FLOAT 6 Inserl Incoming call traffic (incoming call occupation time/period) FLOAT

The network management system without layered and fixed network management indicators has only one kind of information flow, network management data, as shown in Figure 1.

Compared with the above-mentioned network management systems, intelligent network management has its distinct characteristics, that is, the intelligent services running on it will often increase dynamically, and the network management indicators will often change dynamically. There are many network management systems that use unlayered and fixed reporting indicators. Disadvantages: 1. The increase of intelligent services or the change of service index requirements will bring changes in the indicators reported by the network management, and the network management programs will be frequently updated and upgraded, which will increase the development cost of manpower. 2. The on-site network management version will be constantly replaced, which increases the risk of system instability and errors, and reduces customer satisfaction. 3. Since there is no hierarchical system for network management data provision and data reporting, the business developers of telecommunications equipment and network management developers are too closely connected, the modularity of the system is low, and situations such as unclear responsibilities and duplication of labor are prone to occur. The cost is high.

In view of the above, it is necessary to adopt a new technology and method to enable the network management system to have the function of dynamic scalability (dynamic reporting, dynamic collection, dynamic display) of data index reporting.

Contents of the invention

The object of the present invention is to solve the above-mentioned problems, and propose a dynamic self-adaptive intelligent network management system and its implementation method, which can enable the network management system to have the function of dynamic scalability of data index reporting.

The network management data collection point establishes a TCP/IP data link with multiple network management interface machines to receive data information from multiple intelligent network domains. The output of the network management data collection point is connected to the network management server point, and the network management data and the meaning description information of the network management indicators are reported to the network management server point. The network management server point is a server for storing, processing and providing various network management applications. Its output is connected to the network management Access point, the network management access point is the user network management access interface terminal, which intuitively displays, analyzes and processes network management data in various ways.

A dynamic self-adaptive intelligent network management implementation method, which adopts a layered architecture of network management data supply layer, network management data reporting layer, network management data collection layer, network management data display layer, and the network management interface machine of the network management data reporting layer reads the network management system There are two types of information in the intelligent network domain of the data providing layer. One is the network management data reporting information, which only includes the reported data information of the network management, and the other is the meaning description information of the network management indicators. Meaning, and the interface protocol package defined by the second type of network management information flow is sent to the network management data collection point of the network management data collection layer through the TCP/IP data link. The network management data collection point establishes communication with multiple network management interface machines, which is responsible for receiving And process, decompose and restore the network management information flow, and send the decomposed second-type network management information flow to the network management server point of the network management data display layer.

Detailed ways

The present invention is composed of NMI (network management interface), NMCP (network management collection point network management data collection point), NMSP (network management server point network management server point), NMAP (network management access point network management access point).

NMI is the network management data reporting point. It establishes communication with the intelligent network domain SMP, and uses the database coupling method for data interaction. The intelligent network domain SMP and SCP are network management data providing points. An ASON domain corresponds to an NMI. NMCP receives data information from multiple intelligent network domains, establishes TCP/IP data links with multiple NMIs, and reports network management data and network management index meaning description information to NMSP. NMSP is the core equipment of the network management system. It is a server for storing and processing network management data and providing various network management applications. Provider information about the quality of intelligent network operation and the economic benefits of operation.

The present invention adopts the layered architecture of network management data supply layer, network management data reporting layer, network management data collection layer and network management data display layer, designs corresponding dynamic data access structure, and formulates corresponding dynamic interface protocol to realize intelligent The dynamic increase of business and the change of demand change the functions of network management data dynamic reporting, dynamic collection and display.

There are two types of information flow in the present invention, one is network management index meaning description flow, which defines the specific meaning of each index reported by network management data, and the other is network management data reporting flow, this data flow only includes the reported data information of network management. When there is a change in the smart service or the reporting of the network management indicators, the reporting mechanism of the meaning description of the network management indicators will be triggered, and the latest network management data indicator meaning description will be reported to the NMSP, and the new network management data will also be reported to the NMSP at the same time. Description Displays the reported network management data. Through this processing mechanism, the intelligent network management system is independent of the data supply point. Changes in the network management reporting indicators caused by the loading of value-added services in the intelligent network domain will not affect the network management system. The system has reliable dynamic scalability.

The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

As Fig. 3, network management system of the present invention is made up of NMI (network management interface machine), NMCP (network management data collection point), NMSP (network management server point), NMAP (network management access point), and NMI is the data reporting point of network management system, It establishes communication with the Smart Domain SMP, one for each Smart Domain. In order to improve the stability of data acquisition, NMI and SMP adopt the database coupling method for data interaction, and the method of data communication by reading and writing database tables is called database coupling interaction. NMI reads two types of information of the intelligent network domain, one is the information reported by the network management data, and the other is the description information of the meaning of the network management indicators, and sends the dynamic interface protocol package defined by the second type of network management information flow to the NMCP through the TCP/IP data link . NMCP is the data collection point in the network management system, and establishes communication with multiple NMIs. It is responsible for receiving and processing, splitting and restoring the network management information flow, and sending the decomposed type II network management information flow to the NMSP. After NMSP receives the information flow of NMCP, it stores it in the database according to the defined dynamic data structure. NMSP is the core equipment of the network management system, and it is the server for network management data storage, processing, display, report, analysis and other network management applications. NMAP is the user terminal of the network management, which is connected to the NMSP through the web, providing users with the ability to remotely observe and analyze the operation status of the network equipment of the telecom intelligent network.

FIG. 4 shows a structural diagram of a specific network group of the network management system of the present invention. Each intelligent network domain is equipped with an NMI. In order to save costs, the NMI can be placed at the location of the intelligent network domain with a PC with slightly better configuration. There is one NMCP and one NMSP in the system, and the local area network where the NMCP is located establishes data links with each NMI for communication through DDN dedicated lines and other methods. According to the capacity required by the network management, NMSP can use different servers. If the system capacity is not large, NMCP and NMSP can be integrated to reduce costs. NMAP can be connected to NMSP in a variety of ways, such as using the same local area network as NMSP or Internet access, so as to provide users in different network segments and regions.

The present invention designs a network management data providing layer, a network management data reporting layer, a network management data collection layer, and a network management data display layer layered system, and defines two types of information flows, as shown in FIG. 2 . The intelligent network domain of the telecommunication equipment is at the network management data providing layer, the network management interface machine NMI is at the network management data reporting layer, the network management collection point NMCP is at the network management data collection layer, and the network management server NMSP is at the network management data display layer. The four-layer structure is independent of each other, the module structure is clear, and it is developed separately. There are two types of information flows in the system. One is the network management indicator meaning description flow, which defines the specific meaning of each indicator reported by the network management data. The second is the network management data reporting flow. This data flow only includes the reported data information of the network management. The intelligent services and network management indicators are provided by the telecom equipment business developers, and the network management system does not need to care about them. The development of the network management system and the intelligent network domain network management data supply point are separated and do not affect each other.

The dynamic interface protocol is a protocol adopted by the second-class network management for reporting information flow. The data reported by the network management can be divided into several categories. For example, the intelligent network network management data can be divided into traffic data, service user information data, and equipment resource information data. These types of network management data need to be classified in advance. Each category of network management data includes multiple subcategories. For example, the category of network management traffic data includes PPS (prepaid) service, VPMN (virtual private network) service network management subcategory data, etc. Network management sub-category data has multiple reporting domains, which are the specific data indicators reported by the network management, such as PPS service traffic statistics include statistical indicators such as the number of call attempts, the number of connections, and the number of responses. The number of subcategories, subcategory names, and the number and names of specific indicators reported by each subcategory of network management data are dynamically changed and provided by the intelligent network domain developers. The dynamic interface protocol definition consists of three parts: message header, network management information flow identification header, and network management information flow. As shown in the following table:

Header Network management information flow identification header Network management information flow

The message header includes the message type identifier and the total length of the message. The message type identifier defines what kind of data reporting flow this data packet is. For example, 1000 indicates the network management data reporting flow, and 1005 indicates the network management indicator meaning description flow. The composition of the network management information flow identification header can be shown in the following table:

Large category identification Subcategory ID The number of sub-category data reporting indicators

The major category identifier is pre-planned and defined. For example, the value 1 represents the major category of traffic data, and 2 represents the major category of service user information data. The subtype identification value and the number of subcategory data reporting indicators are indeterminate, and are given by the smart domain developer. There are two types of network management information flow, and the definition of network management index meaning description flow can be as follows:

Subcategory meaning Meaning of data indicator 1 Meaning of data indicator 2 … Meaning of data index n

Each field can be separated by invisible characters, such as carriage return and line feed. The network management data reporting flow definition can be as follows:

Data 1 Data 2 … data n

It can be seen from the above that there is a one-to-one correspondence between the data in the network management data reporting flow and the network management index meaning description flow and its meaning description, so that after the network management information is reported to the NMSP, the correctness of the network management data is guaranteed.

The dynamic data access structure is the data structure in which the network management server NMSP stores the second-class network management data. Define the subcategory meaning description table and the network management data index meaning description table to store the network management index meaning description flow. Each category of network management data defines a data storage table. For example, intelligent network management can define traffic data tables, service user information data tables, and equipment resource information data tables. The traffic data table can be defined as follows:

serial number Field Name field meaning 1 SubDataID Subcategory ID 2 Data1 Data 1 3 Data2 Data 2 ... ... ... n+1 Data_n Data n

Among them, the fields Data1, Data2, ..., Data _n in the table are data fields. The value of n is the maximum number of indicators reported by the subcategory network management data in this category. If the number of indicators reported by the subcategory network management is less than n, the value of the Data field that is greater than the number of indicators can be 0. The meaning description table of network management data indicators can be defined as follows:

serial number Field Name field meaning 1 DataID Large category identification 2 SubDataID Subcategory ID 3 DataField Data field name 4 DataFieldName Description of the meaning corresponding to the data field name

DataField is the name of the data field in the data storage table, and its values are Data1, Data2, ..., Data _n . When displaying and analyzing the data in the data storage table, the corresponding name can be obtained by querying the field meaning description in the data index meaning description table. This data table structure definition provides a method for dynamically accessing network management data and describing the meaning of network management indicators for two types of network management information.

The network management access point NMAP displays the reported network management data according to the meaning description of network management indicators. The network management index meaning description and network management data two types of information flows are reported by the network management interface machine NMI to the network management server NMSP. When there is a change in the intelligent service or the report of the network management index, the reporting mechanism of the meaning description of the network management index will be triggered. The flow chart is shown in Figure 5. When there is a change in the network management data reporting index, the intelligent network domain data supply layer will write the message command event in the intelligent network domain message command table into the network management report index meaning change message command event, and the NMI will read the intelligent network domain message command table regularly and receive the network management report. After the indicator meaning change event, read the changed network management indicator meaning description from the SMP message command table, and form a data packet and send it to the NMCP. NMSP, NMSP stores the received network management index meaning description report package into the database according to the defined dynamic data structure, and when NMAP accesses NMSP, it displays the reported network management data according to the latest network management data index meaning description. Through this processing mechanism, the development and upgrading of the intelligent network domain will not affect the network management system, and the network management system will automatically adapt to the dynamic changes of intelligent services or network management indicators, without the need for continuous development and upgrading.

The following takes the PHS intelligent network management system of a certain province as an example to further explain.

There are three PHS smart network domains in this province, which are located in three different cities. The three intelligent domains have four, three, and two sets of SCPs respectively.

In the system, 3 PCs are used as NMI (network management interface), which respectively establish communication with the SMPs of each intelligent network domain, and place them in the cities where each intelligent network domain is located.

Set up a set of HP L2000 server as the network management data collection and network management server system integrating NMCP and NMSP, and connect to three network management interface machines NMI through TCP/IP data link. The NMAP client connects to the network management server through the web, and provides network management interface functions such as network management data display, report, printing, and analysis of network operation quality and operation efficiency.

At the beginning, the SCP only loaded the PHS service (prepaid service). During the operation process, several network management indicators were added, and the PHS service was modified and reloaded. With the expansion of the service, other intelligent value-added services were launched. Such as UPT service (one number service), OneNumber service, etc., if a network management system with fixed network management indicators is used, at least three post-development and upgrades are required, which wastes manpower and material resources and increases the instability of the system. With the intelligent network management system with dynamic scalability of the present invention, the network management system will automatically report and process the network management data showing the increase of the above-mentioned intelligent services and the change of network management indicators without any modification, providing operators with instant and effective intelligent network Operation index information greatly saves development and after-sales maintenance costs and improves customer satisfaction.

The invention can be widely used in fixed intelligent network, mobile intelligent network, CDMA intelligent network and PHS intelligent network, and also supports integrated intelligent network system, and provides a stable and reliable network operation index analysis tool for telecommunication operators. The invention can also be used in other non-intelligent network telecommunication network management systems whose requirements for network management indicators change frequently.
