Abstract
The present invention relates to a method for realizing the MTP in a fully distributed mode. An MTP network management message is processed by a module in which a real link is positioned; when a fault occurs in the module, the message is processed by a module in which a link receiving the message is positioned; other related modules is notified of a network management message which affects other modules by a module which processes the message in an internal protocol mode. The realization method can support the operation that a communication mechanism running under a multi-module environment is applied to establishing a maintenance management system which benefits users' use, ensures that when a fault occurs, the influence on the communication function of the whole MTP part is minimized, and effectively avoids the fault pervasion caused by a main control device fault.

Technical field
The present invention relates to the network communications technology, more particularly, relate to a kind of method that can be used for realizing signalling system No.7 MTP a kind of full dispersion realization MTP (Message Transfer Protocal, Message Protocol) partly.
Background technology
Signaling System Number 7 MTP partly has three layers, its bottom (ground floor) is a physical layer, the second layer corresponds to link layer, the 3rd layer is the network layer part of Signaling System Number 7, this layer is mainly used in the message that receives from the upper strata from the user, and forward this information to lower floor (two layers of MTP) or from two layers of MTP receive message wherein suitable part be sent to MTP user (TUP, ISUP or SCCP).The main purpose of this one deck is for guaranteeing the network node fault or the reliable delivery of signaling message just often, for its upper strata (application layer) provides than the more reliable message transmission of physical layer transmission passage.Its basic signaling protocol does not allow more or less external function by Q.70X series of canonical and Chinese national standard MTP part specific definition.But it leaves bigger space on implementation method and maintenance management method.The outer chains mouth interface features of MTP layer since be subjected to specification limits and must with other type compatibilities, have no flexibility.Because standard only proposes basic demand to maintenance management, its expansion must be defined by implementor oneself; In addition, though standard realizes that to inside the method for MTP function has the summary definition, need on the basis that guarantees the external behavior unanimity, adapt to the soft or hard environment.Can offer in the implementation of Signaling System Number 7 MTP part in prior art, exist the implementation method shortage of communicating by letter under the multimode, surface to fail to provide enough the level of details and make consistency be difficult to guarantee.In communication process, when three layers of MTP learnt link failure or find in the signaling network relevant portion fault from the message that relevant signalling point is sent here from two layers of MTP, its user of MTP three courses circulated a notice of this variation (comprise point of destination can reach, unreachable and other state variation).
Prior art mainly adopts centralized control method to MTP three layer segments, i.e. all processing are carried out on same processor, and when other parts need be used MTP three layer functions, processor communicated therewith, gave this processor with message and handled.Therefore following problem is arranged: the one, disposal ability is subjected to the single processor capabilities limits, is difficult to adapt to high requirement; The 2nd, in case this processor breaks down, then MTP three layer functions will be lost, and cause other parts normally not carry out simultaneously.By MTP three layer segment functions are distributed to some equipment, might alleviate first problem, but because the incompatibility on the core controlling mechanism still can not fundamentally solve above-mentioned second problem.
Summary of the invention
The object of the present invention is to provide a kind of full dispersion to realize the method for MTP, this communication implementation method mainly is the following problem that will solve in realizing signalling system No.7 MTP part: provide a kind of and can support operational communications mechanism under the multimode environment, this communication mechanism can provide prior art still unappeasable reliable communication, guarantee when breaking down the influenced minimum of whole M TP part communication function.-
Another object of the present invention is to provide a kind of full dispersion to realize the method for MTP, this communication implementation method can realize in SP with multimode or STP system that the dereliction of MTP part is from full decentralized control, thereby strengthen the equipment integral reliability, the traffic handling capability of raising system is avoided simultaneously effectively because the large tracts of land fault diffusion that core main control device fault causes.
The object of the present invention is achieved like this, a kind of full dispersion realizes the method for Message Protocol, this method is to realize in a system that comprises the module that comprises Message Protocol by internal communication link interconnection a plurality of, it is characterized in that, the link of each module is divided into real link and interior link, for the processing of Message Protocol network management messages, by real link place resume module; When this module failure, handle by the link place module of receiving this message; To influencing the network management messages of other modules, notify other correlation modules in the internal agreement mode by the module of handling this message.
Realize the method for MTP according to a kind of full dispersion provided by the invention, it is characterized in that, in described a plurality of MTP module each is performed such communication process, when receiving the message that belongs to this resume module, carry out normal process and carry out the detection that state changes, if state variation then broadcast this state variation; When receiving the message that belongs to other resume module, forward this information to described other modules; When receiving the message that the bottom state changes, carry out normal process and carry out the detection that state changes, if state variation then broadcast this state variation; When the message received from other module, carry out normal process; When receiving the state variation message of other module broadcasting, carry out normal process.
Method according to a kind of full dispersion realization MTP provided by the invention is characterized in that said state variation comprises routing state variation, link-state change etc.
Realize the method for MTP according to a kind of full dispersion provided by the invention, it is characterized in that said normal process is the various processing of specifications recommend, when being defined as external transmission message, should carry out following steps: check that whether should be this module sends this message, if should not send, then not send this message by this module.
Implement the method that a kind of full dispersion of the present invention realizes MTP, overcome the shortcoming and defect that the centralized control of MTP three layer segments brings in the prior art fully, make disposal ability large increase arranged than single processor, and, whole M TP three layer functions are unaffected when a processor breaks down, nor influence the normal operation of other parts.Utilize communication means provided by the invention, can also be supported in provides prior art still unappeasable reliable communication under the multimode environment, guarantee when breaking down, the influenced minimum of whole M TP part communication function is avoided effectively because the large tracts of land fault diffusion that core main control device fault causes.
Description of drawings
In conjunction with the accompanying drawings and embodiments, further specify characteristics of the present invention, in the accompanying drawing:
Fig. 1 is the structural representation for the principle of the method that a kind of full dispersion realization MTP of the present invention is described.

Embodiment
In Fig. 1, show three systems that comprise the module 1,2,3 of MTP that comprise by internal communication link 4 interconnection.As shown in the figure, module 1 has three links, and module 3 also has three links, and module 2 does not have link.Because the MTP state externally is unified state, the state of each module must be consistent, otherwise can cause protocol error.Therefore, the MTP of each module part should exchange necessary control information and ask state with Coordination module, and each module should also be included the link of other module in the compass of competency of the MTP of this module simultaneously, is about to the specific link that other module links are considered as this module.
For example, for the structure among Fig. 1, each module should comprise link as shown in Figure 2.Wherein, module 1 has three interior links and three real links, and module 2 has 6 interior links, and module 3 has three interior links and three real links.Like this, each module is all managed 6 links, and the link that has is directly external, is real link; The link that has is interior link in other module.For the processing of MTP network management messages, in principle by real link place resume module; When this module failure, handle by the link place module of receiving this message.To influencing the network management messages of other module, notify other correlation module in the internal agreement mode by the module of handling this message.
Fig. 3 has illustrated the Message Processing flow process of individual module, when this module is received should be by the message of this resume module or bottom state reporting message the time, carry out normal process and carry out the detection that state changes, if state variation then broadcast the variation of this state to all modules; Receive not when this module and to forward this information to corresponding module and to go to handle should be by the message of this resume module the time; When the message received from other module, carry out normal process; When receiving the state variation message of other module broadcasting, carry out normal process.
Wherein, said state variation comprises routing state variation, link-state change etc., and other state also can therefrom be derived;
Wherein, said normal process is the various processing of specifications recommend, when being defined as external transmission message, should carry out following steps: check that whether should be this module sends this message, if should do not sent by this module, then do not send this message.
Each module is handled simultaneously to the state variation of link or route etc., is with the difference of standard, only externally sends message by designated module, rather than all modules outwards send message simultaneously.
