Description
Technical field
The present invention relates to the control method of the two-way supervision of a kind of network management system and Element management system (Element ManagementSystem) or network management system and network element (Network Element) operating state, the invention belongs to the communication network management field.
Background technology
Under network management environment, a basic premise condition finishing the management function of network management system is that the management information between the multiple network management resource key element that realizes in this system is mutual, management information between, Element management system mutual as, the management information between network management system and the Element management system (agency) and the network element (agency) is mutual etc.From the theoretical and real network management project practice situation of webmaster, the interactive mode of network management information generally adopts interface mode, that is, manage the mutual of information by the network management interface of between different network management resource key elements, setting up standard or privately owned negotiation.Fig. 1 has expressed network management environment lower network management system by the interface relationship between the guard system.
According to the flow direction of network management interface two ends communication data, communication can be divided into from network management system flow to by the down direction communication of guard system with communicate by letter from the up direction that is flowed to network management system by guard system.For the network management entity that is in the network management interface two ends, communication each other can be divided into 3 kinds, as schematically shown in Figure 2.Among Fig. 2, first kind of communication is that network management system is to the management operation request of being initiated (issuing) by guard system; Second kind of communication is sent by the request of guard system response to network management system replys (uploading); The third by guard system initiatively to the unidirectional event notice that reports of network management system (uploading).
From up direction, in existing webmaster theory, the event notice that is initiatively reported network management system by guard system is unidirectional, that is, whether the event notice that be need not to obtain reporting by guard system finally arrives the affirmation of destination.In engineering practice, if, might be lost by the event notice that guard system reports by the interrupted communication link (or the network management system of communicating by letter with it breaks down) between guard system and the network management system.Break down if can be found the communication link (comprising the network management system application entity) of its reported event notice in advance by guard system, can be adopted some remedial measures, as alarm log etc. by guard system.From the another one aspect, if management system allows, when the problems referred to above occurring, can also partly be taken over the function of network management system by guard system, improve the quality of network management.This shows, be very necessary by guard system to the function for monitoring of the operating state (comprising communication linkage) of up direction network management system, and this also is a function that lacks in the present network management practice.
From down direction, the existing network management system possess that certain automatic discovery communicates by letter with it by the ability of guard system application entity (comprising communication linkage) operating state.As, for first kind of situation among Fig. 2, when network management system and by between the guard system communicate to connect or when being gone wrong by guard system related application entity, network management system sends to by the operation of guard system and can't send to or not response, at this moment, network management system will obtain prompting, thus can find to be attached thereto problem has been appearred by guard system or communication linkage.If but network management system is not initiatively initiated operation, so, in its initiates the time interval of next operation, network management system can't be initiatively or find in advance communication with it by the guard system problem of (comprising communication linkage).In this case, network management system can be received the event notice that reports.If but network management system is not when receiving the event notice that is reported by guard system in a very long time, network management system is actual can't be distinguished and gone wrong by guard system (comprising communication link) on earth or be in normal operating conditions by guard system and only be not report notice.This shows, in existing network management project practice, still need to strengthen network management system down direction is communicated by letter with it by the guard system surveillance coverage of (comprising communication linkage).
In sum, angle from the network management system overall situation, for the quality that improves network management, the reliabilty and availability that ensures network management system, the webmaster application entity that is necessary for the network management interface two ends is set up the mechanism that the operating state to the other end (comprise but do not distinguish the communication linkage of bearer network interface tube) monitors respectively, simultaneously, this supervision should be two-way supervision.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of control method that is used for monitoring network management system operating state, specifically, is to the network management system and the control method of being carried out two-way supervision by operating state between the guard system.
The method of the invention comprises the steps:
Step 4 is by the timing confirmation of management system receiving management system timing cycle passback.
Adopt the present invention, can realize network management system with by the two-way supervision of the operating state between the guard system (comprise but do not distinguish the communication link that carries this network management interface).Especially this method can realize by guard system to the management system backward supervision, thereby strengthened the reliabilty and availability of system greatly, take measures necessary for system's relevant portion and created precondition, improved the management quality of network management system.

Embodiment
About Fig. 1, Fig. 2, partly done argumentation in background technology, repeat no more herein.
Fig. 3 is the two-way follow-up work principle schematic of the present invention, among Fig. 3, network management system be divided into four kinds of situations by communicating by letter of guard system, the one, the bookkeeping that network management system is initiated; The 2nd, by replying that the guard system operation that management is initiated to network management system is done; The 3rd, the timing information of initiatively on network management system, being sent out by guard system; The 4th, network management system is after receiving " timing information ", and passback " regularly confirmation " is given accordingly by guard system, and passback " regularly confirmation " is the new function that the present invention proposes, thereby has realized two-way supervision.
Fig. 4 has provided concrete implementing procedure of the present invention.
The load mode of timing information is as follows: " operating state timer " sends timing information to by " notification agent " module in the guard system, and the notification agent module is responsible for reporting relevant information to give network management system." notification agent " is the notion that the 3GPP normal structure proposes when the suggestion of definition 3G (Third Generation) Moblie network management interface, " notification agent " can finish general unidirectional reporting events function under network management environment, therefore the service that this function provides also is called as " notification service ".But " notification agent " function of 3GPP normal structure definition only provides a kind of general unidirectional reporting events service ability, and this ability is not applied to monitoring by the guard system operating state as yet.The present invention has used this function when realizing management system to the function that monitored by the guard system operating state.Network management system is according to the principle of " notification service ", as long as event notice to " notification agent " predetermined respective type, just can receive the corresponding event notice that " notification service " transmitted, the interface communication after the introducing " notification agent " as schematically shown in Figure 5.
Among Fig. 5, network management system be divided into 3 classes by communicating to connect of guard system and communicate by letter, be respectively category-A, category-B and C class.
The communication of C class is passed through " notification agent " and incident distribution services communicating by letter to the unidirectional reported event notice of network management system by guard system;
Category-B communication is the two-way interactive between network management system (manager) and " notification agent ", as manager's scheduled event notice etc.;
Category-A communication is by communicating by letter between all kinds of agencies of guard system (as, performance management agency, fault management agency and configuration management agency etc.) and the network management system (manager).
The present invention is defined as a kind of event notice with " the operating state timing information " that timer produces, and the network management system of predetermined this event notice can be handled and be uploaded to this event notice by " notification service ".The parameter format of " the operating state timing information " of the present invention's definition is as follows: first: event time (EventTime); Second: system identifier, the unique identifier that this symbolic representation is acted on behalf of by guard system; The 3rd: notification type (Notification Type), it represents the event type of this event notice representative; The the 4th: cycle (Period), the cycle that its expression timer produces timing information; The 5th: " notification agent interface " number (Notification Interface Id), this is an integer data type, is used for ID number of expression " notification agent interface ".
Adopt above step, management system can comprise the working condition of the link of notification agent, notice distribution services, the communication of carrying C class, but not distinguish this 3 kinds of situations being monitored by the operating state of guard system.
In order to improve the flexibility of management, the present invention provides the method for obtaining and be arranged on the timer cycle that is provided with in the guard system by interface for network management system.Concrete grammar is the corresponding function of structure, calls for management system.Method for designing is as follows:
First: definition " obtaining the timing cycle function ".The input parameter of this function is empty, and output parameter has 2.First be " timing cycle " (Period), promptly call the periodic quantity that returns to caller behind this function; Second is the return state (Status) of function call, and the data type of return state is an enumeration type, comprise operate successfully, two data of operation failure.If the result who calls is " operating successfully ", then expression has got access to the cycle of desiring to obtain; Otherwise the operation failure in cycle is obtained in expression.
Second: definition " the timing cycle function is set ".The input parameter of this function is 1, and output parameter is 1.Input parameter be function calls person's (management system) desire in " timing cycle " that be provided with by the guard system timer (Period); Output parameter is the return state (Status) of function call, and the data type of return state is an enumeration type, comprises (operating successfully operation failure) two data.If the result who calls is " operating successfully ", then expression success is provided with timing cycle in by the timer of guard system; Otherwise expression is provided with the operation failure in cycle.
The working method of network management system triggering for generating and passback " regularly confirmation " can have two kinds.
First kind of mode is for whenever receiving one " timing information ", and network management system just triggers and return one " regularly confirmation ", and operating frequency is identical with the frequency that is produced " timing information " by guard system.
The second way is for after receiving " timing information ", and network management system is carried out the passback that timing information is confirmed according to the affirmation cycle of being set by the guard system timer.
The present invention has adopted second method and has designed one " regularly returning function " and periodically call with passback " regularly confirmation " for network management system.
The input parameter that " regularly returns function " comprises two parameters, first parameter is " a management system unique identifier ", the data type of this parameter is a character string type, used this parameter can distinguish the management system of calling this function by guard system, that is, can confirm to return the management system of timing information.If do not define this parameter, receive can't being distinguished of " regularly confirmation " and return this management of information person's identity by guard system; Second parameter is " call identifier ", the data type of this parameter is an enumeration type, and its value defined is TURE and FALSE, when management system is called this function corresponding value need be set, setting principle is as follows: when management system received " timing information ", this value was set to TRUE; Otherwise this value is set to FALSE.Because after management system is called triggering, just regularly return confirmation, by to parameter setting values, can be confirmed by guard system whether management system has received " timing information " that reports when this information of transmission.
The output parameter that " regularly returns function " is one, and its data type is an enumeration type, and its value defined is ' operating successfully ' and ' operation failure '.The value that management system is returned by function after calling can know whether call operation is successful.
Step 4: by the timing confirmation of management system receiving management system timing cycle passback.If do not received regularly confirmation by guard system, then enter the strategy of management system working condition is judged flow process, lose regularly confirmation to determine contingency, or problem has appearred in management system.
Adopt the method for the invention, can be realized the function that the working condition to the link of the link of management system, the communication of carrying C class and the communication of carrying category-B monitors by guard system, but this function for monitoring is not distinguished above-mentioned three kinds of situations.
It should be noted last that: above embodiment is the unrestricted technical scheme of the present invention in order to explanation only, although the present invention is had been described in detail with reference to the foregoing description, those of ordinary skill in the art is to be understood that: still can make amendment or be equal to replacement the present invention, and not breaking away from any modification or partial replacement of the spirit and scope of the present invention, it all should be encompassed in the middle of the claim scope of the present invention.
