A network management system is composed of three layers of structures, a bottommost layer is an agent module which operates together with LCS system devices of a GMLL, an LCS CLIENT, an E1 pre-machine, etc.; the agent module of each device is connected with a configuration management server (CM) and an SNMP proxy server by a socket communication method, and the CM is mainly in charge of preconfigured flow of the devices; the configuration files of the devices are stored by a hierarchical dendritic XML file mode; when the CM is started, the XML configuration files are analyzed into a chain table to be processed by preconfigured operation, and the chain table is graded by the types of the devices and modules. A network management foreground can downwards transmit dynamic configuration information and performance statistics information to the SNMP proxy server at any time; after protocol conversion, the SNMP proxy server can downwards transmit corresponding configuration requests and performance requests to a device module; after dynamic allocation, the SNMP proxy server can inform the CM to dynamically modify the XML configuration files to realize the synchronous configuration result of the foreground and a background. If the faults of the devices occur, fault information can be reported to the network management foreground by the SNMP proxy server.

Description

A kind of LCS network management method based on hierarchical chained list and dynamic XML technique
Technical field
The present invention relates to the network management method of a kind of location service (LCS), specifically be applied to configuration management, performance management and fault management GMLC (GMLC), LCS client equipment such as (LCS Client) in the LCS system.
Background technology
So-called network management in fact in brief, is carried out reasonable distribution and control with the requirement of satisfying service supplier and the needs of network to Internet resources exactly.
Before the eighties in last century, because high research and development expense, have only some very large communication common carriers just can afford the development of webmaster, so the network management comparatively sealing and original that becomes to a great extent.And some development in the eighties make network management obtain significant progress.A series of agreement has been paved with the next road with the managed network unit communication of a kind of standardized means as SNMP (Simple Network Management Protocol) and CMIP (CMIP) just.Present most of network management system all is to adopt manager/proxy mode, the agency is responsible for a certain specific part management object example in the maintaining network, the manager answers mutual with management object indirectly by sending bookkeeping message to the agency and receiving, and the agency also can pass to corresponding manager with the notice that the management object of being had jurisdiction over sends in asynchronous system ground.Pass through CMIP or snmp protocol pass-along message between manager and the agency.But in implementation procedure, because the mode that each producer realizes is different with emphasis, a monolithic standard though all can realize the basic function of webmaster, implement comparatively complexity, and extensibility not can not get ensureing.
Location service (LCS) claim positioning service again, it is cooperation by wireless terminal and wireless network, determine mobile subscriber's actual geographical position, thereby the service of the information relevant with the position of user's needs is provided, comprise mobile positioning technique and mobile location service two major concepts.Business provides can pass through GSM (CSD), GPRS, 3G, WAP, MMS and SMS equivalent-load, and it is one of intrinsic attribute of mobile communication.
The huge glamour of location-based service is and can sends to correct people to correct information in correct time, correct place.Network management system is as necessary part in the LCS system, bearing and monitoring whole LCS system operation situation, in time finding and solve important tasks such as fault, configuration management.For networking mode and the equipment characteristic that adapts to the LCS system equipment, design a kind of good LCS webmaster architectural framework, strengthen the reliability and the extensibility of webmaster, it is very necessary adopting some newer technology.
The webmaster of existing LCS system adopts the two-tier system of manager/OAMAgent usually, when the configuration protocol stack, at corresponding configuration message corresponding particular state machine is set, and whole network management system and the system configuration coupling of being disposed are very tight.Adopt this LCS network management method, need fix the structure of system in advance, when system dynamics changes corresponding configuration flow or increases and decreases the protocol stack that needs configuration, when carrying out capacity extension, whole LCS webmaster just need be write again, therefore very dumb, be difficult to satisfy the demand of the flexible expansion of whole system.
Summary of the invention
The purpose of this invention is to provide a kind of LCS network management method based on hierarchical chained list and dynamic XML technique, the institutional framework of network management system and function are divided more specific, reasonable, more near actual, be easy to realize, and also safe and reliable, be easy to expansion.
The object of the present invention is achieved like this, a kind of LCS network management method based on hierarchical chained list and dynamic XML technique, it is characterized in that: network management system is made up of three-decker, the bottom is to operate in together proxy module with device server, the intermediate layer is configuration server and SNMP acting server, and the superiors are interface servers;
Wherein equipment can have a plurality ofly, and each equipment all has proxy module; The proxy module of each equipment links to each other with the SNMP acting server with configuration server by Socket (socket) communication mode, configuration server mainly is responsible for the prewired flow process of equipment, its configuration file is stored with XML (extending mark language) file mode, when configuration server starts, resolve earlier this XML file, the configuration messages of equipment is read in the chained list according to device type, module type classification automatically carries out prewired operation; The webmaster foreground can issue dynamic-configuration message at any time and performance statistics message is given SNMP (Simple Network Management Protocol) acting server, the SNMP acting server is handed down to EM equipment module through after the protocol conversion with corresponding configuring request and capability request, after dynamic-configuration is finished, the SNMP acting server can notify configuration server dynamically to revise the XML configuration file, to reach the effect of AM/BAM configuration synchronization; If device fails can be reported the webmaster foreground by the SNMP acting server.
Aforesaid LCS network management method is characterized in that: each in the configuration data array all is the chained list of a classification, at first is to link by module, links by message again in each module; Configuration file on the CM server is stored with the XML mode of hierarchical tree, comes the configuration messages of indexing apparatus by configuration object ID.
Aforesaid LCS network management method, it is characterized in that: after CM starts, the XML configuration file is configuration messages and being articulated to by device type, module type in the hierarchical chained list of configuration data array with resolved, need initialization MOC tree and MIT tree therebetween, pre-timing is directly by configuration messages in the device type down distributing configuration data array linked list of request and the configuration of support single module.
Aforesaid LCS network management method, it is characterized in that: SNMP AGENT can dynamically revise the XML configuration file by configuration messages by notice CM after finishing dynamic-configuration, in this process, to revise MOC tree, hierarchical chained list and MIT tree successively, at last the MIT tree is saved in to finish in the XML file and on-the-fly modify process.
Basic principle of the present invention is: based on existing manager/proxy mode, adopt the configuration messages of XML file mode memory device, and realize on-the-fly modifying of XML configuration file in dynamic-configuration when success, simultaneously prewired function is separated independent realization, the system that makes also can carry out prewired operation according to the configuration file of the last time success under the situation that does not have the webmaster foreground.
Advantage of the present invention is:
(1), extensibility is good.Owing to adopt the configuration information of layering XML file-storage device, with the form of hierarchical chained list the message in the configuration file is carried out chaining (referring to accompanying drawing 2) again in the configuration server simultaneously, when LCS system equipments such as increase GMLC, revising corresponding XML configuration file and carrying out once more chaining is very easily, the level and smooth expansion of feasible system.
(2), the advantage with XML mode store configuration files is: (a) XML is the key technology in the following Web platform, only just can accomplish the real fusion of network management technology and WWW technology with XML form storage network management data.(b) with XML form storage network management data good immanent structure is arranged not only, also be easy to carry out data and exchange and develop.(c) existing webmaster standard such as SNMP have determined network management data to meet hierarchical structure and object-oriented principle, and these 2 perfectly in harmony with the XML standard, and this makes with XML form storage network management data very natural.
(3), maintainable good.Can carry out dynamic-configuration to equipment easily by the webmaster foreground, for example the E1 front end processor be increased or revise a signaling point code, configuration server can be revised configuration messages in configuration file and the hierarchical chained list or configuration item as required dynamically.These operations are all carried out on the webmaster foreground, need not other equipment in the LCS system are made amendment.
(4), redundancy is good.Because configuration server keeps the AM/BAM configuration data consistent by on-the-fly modifying the XML configuration file with hierarchical chained list, therefore under the situation that does not have interface server and SNMP acting server, the LCS system also can carry out prewired operation according to the configuration file of the last time success, add SNMP acting server and interface server later on, also can not influence previous network configuration.

Fig. 2 is the structural representation of hierarchical chained list of the present invention.After configuration server starts, configuration server can parse the configuration messages of each equipment in configuration data array 201 from the XML configuration file, configuration data array 201 is come index by device type, for example slave unit 202 is to equipment 203, in the configuration data array 201 each all is the chained list of a classification, at first be to link by module, for example equipment 202 chains are connected to the configuration item of module in this equipment 204 to module 205, secondly chain is connected to all configuration messages of this module below each module, and for example chain is followed the configuration messages of this block configuration 206 to configuration 207 below the module 204; Adopt the structure of this hierarchical chained list can be well the actual conditions of XML document analysis and equipment disposition to be combined, reduced the difficulty of XML document analysis, increased the readability of XML file, thereby under the situation that does not have the webmaster foreground, we also can manually revise configuration file.When the proxy for equipment module when configuration server sends the request configuration messages, configuration server can according in the request message with device type from configuration data array 201, find the corresponding apparatus item, by module type the configuration messages in the chained list is issued to corresponding apparatus one by one then and finishes prewired process, adopt the also configuration of single module in the support equipment simultaneously of this kind structure.After finishing the dynamic-configuration operation, the SNMP acting server can be notified the configuration messages in the configuration server renewal configuration data array 201.
Fig. 3 is a dynamic XML file structure schematic diagram of the present invention.What the XML configuration file in the native system adopted is a kind of hierarchical tree structure, top layer is a system configuration data 301, wherein comprise the global configuration information of whole LCS system and the link information of its each equipment of lower floor, for example slave unit 1 302 to equipment N 304, can retrieve all equipment disposition message from system configuration data 301 like this; Equipment also comprises its lower floor's configuration object, for example lower floor's configuration object of equipment 1 302 is a module, comprise module 1 305 to module N306, lower floor's configuration object of equipment N 304 then is an integrated circuit board, comprise integrated circuit board 1 307 to integrated circuit board N 308, equipment and integrated circuit board all include the global configuration information of this configuration object and the link of lower floor's configuration object, in the drawings, integrated circuit board 1 307 just includes the link of module 1 311 to module N 312, the configuration object that module comprises the bottom is a message, and for example module N 312 comprises configuration messages 1 313 to 314 some configuration projects of configuration messages N.In the XML of this hierarchical tree file structure, we can search the configuration information of arbitrary configuration object easily, it is consistent with the layout of physical device, from figure we as can be seen system form by server, machine frame, integrated circuit board etc., thereby if increase or reduce the same equipment, revising configuration file is very easily.
Fig. 4 is a hierarchical chained list message chaining flow chart of the present invention.Hierarchical chained list in the configuration server is mainly used to carry out the prewired process of equipment, and the 401st, the chaining process of hierarchical chained list:
When (1) step 402 is illustrated in the configuration server startup, at first can initialization ApiMap, ApiMap is realized by a MOC (Managed Object Class) tree, main purpose is that the object ID with equipment, module and the message of needs configurations records in the MOC tree, is used for the configuration object of those needs of chaining and message.
(2) the XML configuration file is opened in step 403 expression.
(3) step 404 expression is loaded into the XML file in a MIT (the Management Information Tree) tree, and the hierarchical tree structure of MIT tree and XML file is in full accord, has recorded faithfully configuration object and configuration messages in the XML file.
(4) message during step 405 expression is set MIT by the configuration object ID that writes down among the ApiMap in the configuration data array, is finished the chaining process by the sizing of equipment chaining.
Fig. 5 is a dynamic XML file modification flow chart of the present invention.After dynamic-configuration was finished, the SNMP acting server can notify configuration server dynamically to revise the XML configuration file, and 501 have described this process:
(1) the modification configuration request message from the SNMP acting server has been received in step 502 expression, in the message, has the configuration information of finishing dynamic-configuration.
(2) step 503 expression is revised ApiMap according to the configuration object under the message, promptly revises the configuration object ID in the MOC tree, and doing like this is the effect that can reflect dynamic-configuration for next chaining.
(3) step 504 expression makes once more chaining just can carry out new prewired flow process according to the message chained list in the message modification configuration data array.
(4) step 505 expression is the XML form with message conversion and revises configuration data in the MIT tree according to this, can keep consistent in configuration information and the XML file in the MIT tree like this.
(5) step 506 represents that the MIT tree that will revise is saved in the XML file, finishes on-the-fly modifying of XML, and the AM/BAM configuration data is consistent.
Above the invention has been described in conjunction with example, should point out, those skilled in the art can make the change on various forms of and the details, and do not depart from by the determined the spirit and scope of the present invention of claims.
