Description
One, affiliated field
The invention belongs to a kind of signaling process mode of field of telecommunications.Be specifically related to a kind of No.7 signalling system of multi-module structure, be implemented in the method for between a plurality of modules of system SCCP (SCCP) task of Signaling System Number 7 being carried out distributed treatment.
Two, background technology
In the No.7 signalling system of single module, the task of each functional level of Signaling System Number 7 is all finished by a module, and its system processing power, reliability and efficient all are restricted.And the No.7 signalling system of multi-module structure can well improve such drawback.In the multimode No.7 signalling system, signaling process adopts the module redundancy structure of N+M.The task that other resource allocation administration module is finished the driving of network and managed each signaling process machine state.If certain signaling processing module breaks down, task on this module is switched on the standby processing module, if standby processing module breaks down again, resource management module will according to certain algorithm with all link assignment of malfunctioning module to other signaling processing modules.In this multi-module structure, for signaling network management level (MTP3) and under the task of each functional level be that mode with load sharing is distributed on a plurality of modules.And be to finish by a primary module in a plurality of signaling processing modules for the task of SCCP and above each functional level (transaction-capable applying portion TCAP, Operation and Maintenance Application Part OMAP) thereof.Primary module can be specified by manmachine command, or is upgraded to primary module automatically by other module when breaking down.This structure of finishing the signaling process task jointly by a plurality of modules has increased the capacity of system greatly, has improved the disposal ability and the reliability of system.(referring to accompanying drawing 1)
Yet the structure of this multimode is not perfect.Its existing shortcoming is that this multi-module structure is not realized the distribution process of each functional level task of Signaling System Number 7 on a plurality of modules fully.Since to SCCP and on the task of each functional level handle by a primary module, so the processing mode of single module structure has in fact still been adopted in the processing of these high functional levels, has not improved the ability of these upper-layer functionality level tasks of system handles to a certain extent.
In the No.7 signalling system of multi-module structure, for these high functional levels (SCCP, TCAP), what a plurality of modules were used is same local resource.And in fact to the using and manage by local No.7 signalling system and distribute voluntarily and manage of local resource, the signaling system of far-end is unknowable to the allocation manager mechanism of this resource.Therefore, can be on the basis that does not influence systematic function, a shared local resource task of this locality be distributed in each module and goes, to realize the distributed treatment of task.Here, the applicant has proposed the distribution task transaction module of SCCP functional level in a kind of No.7 signalling system.In this model, the applicant has solved when using same local resource reasonable distribution and management local resource between a plurality of modules, and the mutual collision problem when effectively avoiding resource to use, realized that the distributed task scheduling of SCCP functional level is handled in the No.7 signalling system.
Three, summary of the invention
Main purpose of the present invention is to provide a kind of SCCP (SCCP) distributed task scheduling processing method of multimode No.7 signalling system, handle the performance of upper-layer functionality level (SCCP) task to improve No.7 signalling system, thereby improve the disposal ability and the reliability of whole system greatly, increase the capacity of system.Improve existing multimode No.7 signalling system, the characteristics that make its multimode share task all demonstrate fully on each functional level of Signaling System Number 7.
Proposed by the invention is a kind of thought of distributed treatment task, and a kind of method of using and managing public resource is provided.According to this method, can apply it in other the functional level according to the characteristics of each functional level, improve the mechanism that distributed treatment task and resource are shared at intermodule in the multimode No.7 signalling system.
The distributed approach of the multimode No.7 signalling system SCCP task that the applicant proposes, can effectively manage the local reference number resource (LRN) of SCCP, the a plurality of modules that guarantee No.7 signalling system are when a shared LRN resource, resource can not occur and use conflict, guarantee that the LRN of a SCCP is only used by a module.
To achieve these goals, design philosophy of the present invention is to allow the LRN resources bank of the shared SCCP of a plurality of modules, and this resources bank is by global administration's interface (Admin) unified management between SCCP and SCCP user.Each module fixed allocation resource not when system initialization.Just just apply for a part of LRN resource when a module starts from resources bank, rest parts applies for utilizing or application use once more after the LRN of certain module resource uses up when resource is waited for other modules startups in support in the resources bank.
For example: the No.7 signalling system of certain multi-module structure has two modules A, B.We can specify each module to apply for i LRN resource according to systematic function at every turn.Like this, when modules A started, continuous i LRN resource of application used as the initial LRN of oneself from resources bank, and promptly LRN is: 0～i-1.After this when module B started, the LRN of application was continuous i LRN since i, i.e. i～2*i-1.After i initial LRN of modules A used, modules A just proposed to apply for once more the request of LRN resource to resources bank again, and the LRN that please arrive in this moment be continuous i LRN since 2*i, i.e. 2*i～3*i-1.
Based on such implementation, how resources bank effectively to be managed, the conflict that utilizes existing resource fully and effectively avoid resource between each module to use is the problem that this model emphasis will solve.
A global resource allocation table is all set up in design in the internal management interface In_Admin of the interface Admin of global administration and other each modules of system.When each module is applied for resource at every turn, file an application to the Admin management interface earlier, Admin sends Requisition Validation according to the resource allocation table of distribution condition renewal oneself to the module of filing an application, and notifies the In_Admin renewal global resource table separately of other each modules.
Simultaneously, when certain module is received a piece of news, can inquire about local global resource table, when really admitting a fault about the message of this module LRN and finding out module under the message, this message directly can be sent to correlation module.This just needs asking of each module to connect each other, to realize the forwarding of message.
In addition, when applying for resource owing to module, the application module just to application request of Admin, is inquired about the global resource allocation table by Admin oneself, distributes one section LRN resource of fixed number, and returns to the application module at every turn.The application and the releasing operation that have so just guaranteed resource all are that monoblock is carried out, and the situation of scattered resource can not occur, also can not cause the chaotic and waste in the resource management.
Except SCCP towards the coupling part, for among the SCCP towards no coupling part, because it does not relate to local LRN resource, therefore can select the minimum module of current task amount to realize the load sharing of connectionless information between a plurality of modules by the task amount of Admin according to each module.Perhaps specify a special module to come treated side to connectionless message by system.Adopt which kind of implementation to depend on concrete enforcement.

Five, embodiment
For a more clear understanding of the present invention, below in conjunction with accompanying drawing detailed technology content of the present invention is described in further detail.5.1 in traditional multimode No.7 signalling system structure, SCCP task handling mode
In traditional multimode No.7 signalling system structure, the task of SCCP is handled by a primary module, and other modules are the task of treatment S CCP not.When primary module breaks down, will take over task on the primary module by spare module.If spare module breaks down again, resource management module will according to certain algorithm with all Task Distribution of malfunctioning module to certain normal signaling processing module.(referring to accompanying drawing 1) 5.2 single users' SCCP distributed task scheduling implementation
For the multimode No.7 signalling system that has only a SCCP user, between SCCP user and SCCP functional level interface, increase global administration's interface (Admin), managing throughout increases an internal management interface (In_Admin) separately on the module.The SCCP distributed task scheduling implementation of (referring to accompanying drawing 2) 5.3 multiuser architectures
For the multimode No.7 signalling system that a plurality of SCCP users are arranged, the basically identical of the function of each module, interface and single user model in the model, different with single user is to need a plurality of users are connected on the same management interface Admin, and when the message of receiving from the user, by the Admin record user identifications, message and user are associated, so that later on message is sent to user's (referring to accompanying drawing 3) the 5.4 model structures explanation that is associated with it:
The interface Admin of global administration is between the internal management interface In_Admin of the user of SCCP and each module.
The internal management interface In_Admin of each module is between the SCCP of Admin and each module functional level.
Module 1,2,3 ... N is a plurality of processing modules with normal signaling capability of No.7 signalling system, bears all signaling process functions of No.7 signalling system.Processing comprises the signaling task of each functional level such as MTP, SCCP, TCAP.
Spare module is except having processing module 1,2,3 ... outside the signaling process function that N had, also have the link information of other each modules of backup concurrently, when certain module breaks down, take over all abortive functions of this module.
Respectively storing a global resource allocation table among Admin and the In_Admin, the record LRN resource situation that current each module had.
Now that the function declaration of chief component in the model is as follows: 5.4.1 management interface Admin
A, resource storage
Write down the operating position of each module LRN resource, i.e. the resource allocation table of the storage overall situation.
B, resource management
Unified distribution LRN resource manages it.
The management function of Admin:
When a module application resource, Admin sends Requisition Validation according to the resource allocation table of distribution condition renewal oneself to the module of filing an application.
When the LRN resource was arrived in a module application, Admin need notify other each module global resources to change, and upgraded global resource table separately.
When a module withdraws from service, should discharge all LRN resources of once applying for, Admin notifies other module global resources to change, and upgrades global resource table separately.
When certain module enters service, notify this module resource operating position of other each modules at present by Admin, notified module is upgraded the global resource table of oneself.
When receiving the data query request of certain module, need return to the related data of the local global resource table of preserving of request module.
C, message distribution
In single user structure, when receiving one during from message that the user sends, by Admin inquiry global resource allocation table, which module decision should send to this message, and pass-along message is to correlation module.
In multiuser architecture, except aforesaid operations, when receiving one during from message that the user sends, Admin needs record user identifications, is about to message and some users and is associated.When the user sends message, message is sent to the user who is associated with it.5.4.2 the internal management interface In_Admin of module
Storing the global resource allocation table same among the internal management interface In_Admin of each module with Admin, its function mainly is to receive one during from message that the MTP layer is sent, be responsible for judging whether this message is towards connection message, and whether be about this module LRN towards connection message.If not, then inquire about the global resource table, and this message is sent to corresponding module.
Simultaneously, when the internal management interface In_Admin of this module receive one come by other module forwards message the time, if be confirmed to be message about this module LRN, the SCCP that then transfers to this module handles; On the contrary, if not, might be that mistake appears in the global resource table of oneself so, also might be that mistake appears in the global resource table of transmitting that module of message about the message of this module LRN.At this moment this module need send the data query request to Admin and upgrades the global resource table of oneself, and the notice module of transmitting message is upgraded its global resource table simultaneously.5.4.3 spare module
In the process that two peer-entities engage in the dialogue, might cause link unavailable because of some chance failure, thereby make both sides talk with interruption.Interrupt for fear of this dialogue that causes because of link failure, design increases M spare module (number of M is by the decision of concrete system configuration) on the basis of N signaling processing module, be used for writing down the link information that every other each module successfully set up (comprise need in MTP2, MTP3, each function utmost point level of SCCP keep information) specially.When a plurality of spare modules (M＞1), the relation between a plurality of spare modules can be a load sharing, also can be active and standby usefulness, by concrete system's decision implementation.
When some in N the signaling processing module breaks down cannot use the time, spare module is just taken on the module that breaks down all and is successfully set up but also uncompleted connection is professional.After finishing dealing with, remove the relevant information of this connection.When malfunctioning module recovers use,, be somebody's turn to do the new business of talking with on the relevant LRN resource by the resume module of recovering to use for the dialogue of transferring to the spare module processing and having handled.Handle for transferring to spare module, but the dialogue of also not finishing still handled after dialogue is finished by spare module, the LRN resource that this dialogue is relevant just can be continued to use by the module of recovering to use.5.5 send the message flow explanation
Here the flow process that sends SCCP message is described: (referring to accompanying drawing 4)
When SCCP user sent a SCCP message to Admin, Admin judged this type of message earlier.If SCCP is towards connection message, and when being connection request message, the global resource table of Admin inquiry storage finds the module (as modules A) that the LRN resource utilization is minimum in N the module, and this message is sent to the SCCP of modules A, is handled by modules A; If SCCP is towards connection message, but be not connection request message, Admin then finds the module (as modules A) at this LRN place according to the LRN in the message, equally message is sent to the SCCP of modules A, carries out normal signaling message by modules A and handles.If SCCP is towards connectionless information, the global resource table of Admin inquiry storage finds the minimum module of task amount in N the module, perhaps find by the special disposal of system's appointment module (as modules A) towards connectionless information, and this message sent to the SCCP of modules A, handle by modules A; 5.6 receive the message flow explanation
Describe receiving message flow: (referring to accompanying drawing 5)
When the MTP of a module (as modules A) receives a SCCP message, earlier this message is sent to the In_Admin of modules A.In_Admin judges this type of message earlier, if towards connectionless information, then transfers to local SCCP and handles; If towards connection message and be connection request CR, then the global resource table by Admin inquiry storage finds the module (as modules A) that the LRN resource utilization is minimum in the local N module, and this message is sent to the SCCP of modules A, is handled by modules A; If towards connection message but be not connection request CR, then by the global resource table of Admin inquiry storage, whether judge LRN in the message in this module, if belong to the LRN of this module, the SCCP that then calls this module handles this message; If this LRN does not belong to this module, then find out the module (as module B) at this LRN place, send a message to module B again, whether the In_Admin of module B will do same judgement, should be handled by this module to determine this message.5.7 implementation result
This distributed model effectively is being distributed to the task of SCCP on a plurality of modules on the basis that does not reduce systematic function, realizes the distributed treatment of SCCP task.
When certain module can not be used, the task of SCCP can continue to handle on other modules, can not cause the interruption of SCCP business, has improved the reliability of system handles SCCP task.
A plurality of modules can treatment S CCP task, has improved the ability of system handles SCCP task, has increased power system capacity, improves the performance of system.
Realize dynamic allocation of resources and use, made full use of existing resource, avoided the wasting of resources.
Global resource is managed effectively the conflict of having avoided resource to use.
This SCCP distributed task scheduling transaction module proposes at SCCP, but the wherein related this method of using and managing public resource is equally applicable to need to handle other each functional levels (for example: among the TCAP to transaction ID and the management and the use of calling ID) of local shared resources (LSR).According to this method, can apply it to according to the characteristics of each functional level in other the functional level, improve the resource-sharing mechanism between distributed treatment task and multimode in the No.7 signalling system of multimode, improve the Performance And Reliability of whole system from the angle of each functional level.
