Description

A kind of centralized management method of relay resource

Technical field

The present invention relates to the method for managing resource in a kind of communication field switching system, relate in particular to and have the continue relay resource centralized management of switch device of function of traffic resource and speech channel.

Background technology

Along with telephone subscriber's rapid increase, exchanger capacity is also increasing, in the design of switch, the mode of multimode becomes the main flow of switch design gradually, in the design of multimode, and the management of resource, the particularly management of relaying traffic resource seems extremely important.A kind of main method for designing is: will leave in the resource set on certain module (resource module), resource is applied for, inquires about, discharged to business to resource module.This way to manage realizes simple, and the module extensibility is good, realizes the load sharing that traffic resource uses easily, but during this mode specific implementation, not can solve resource and discharged by the business of this resource of unoccupied, causes the problem of existing speech channel aborted.Prior art is No. the 96117990.2nd, Chinese patent application for example, this scheme takies resource and applies for whether the permanent program ID of the processor of release is same by checking application, solve this problem, but because this this method judges is relevant with hardware and the permanent program ID of the operating system processor of being correlated with, and the portability of program is brought certain problem.

Summary of the invention

The present invention seeks to solve the speech channel aborted problem that prior art exists, it is simple to provide a kind of resource management to realize, resource management efficient height, the resources centralized management method that program portability is good.

Core of the present invention is: all relay resource of a switching system are transferred to unique in a system resource management module manage, exchange system business is handled required relay resource and is distributed to this resource management module application by Service Processing Module, and the module id that resource management module takies the Service Processing Module of resource according to judgement guarantees the correct release of relay resource.

The centralized management method of relay resource of the present invention may further comprise the steps:

Resource management module with the resource number centralized stores of relay resource all in the switching system in the relay resource allocation table;

When Service Processing Module needs the relaying traffic resource, send the application that distributes the relay resource numbering to resource management module;

Resource management module is selected available relay resource from the relaying resource allocation table, with the module id of the Service Processing Module of this relay resource of application corresponding to distributes relay resource number preservation, make this relay resource can not be, and the relay resource numbering of being distributed can be fed back to this Service Processing Module by sub-distribution again;

When the Service Processing Module application discharges shared relay resource, whether module id and the relay resource that is required to discharge that the Service Processing Module of this application is initiated in the resource management module inspection numbered pairing module id consistent, if unanimity then allow to discharge, otherwise refusal this time discharges application.

Adopt the method for resources centralized management of the present invention, compared with prior art, the relay resource administrative mechanism of reliable distribution and release is provided, improve the reliability of relay resource management system, the stability of switching system, and used logic module to identify the portability that this method has guaranteed program.

Embodiment

Please refer to Fig. 1, the present invention relates to lower module:

Resource management module is the main realization module of the inventive method, is responsible for the realization of switching system resource management, comprises resource allocation, recovery, condition managing etc.Be provided with resource allocation table in the resource management module, the module id of the Service Processing Module of relay resource is numbered and taken to the relay resource that is used for the memory transactions system.

Service Processing Module comprises the related service processing module that will use relay resource, and as TUP, ISUP, BSSAP etc., they mainly are to use the resource management function that resource management module provides in the present invention.Each Service Processing Module all has a module id unique in switching system separately, this module id is in logic a module id when Business Processing, represented actual Service Processing Module, switching system uses module id to distinguish the actual different individuality of Service Processing Module, module id is by the unified numbering of the principle that guarantees its uniqueness in switching system, place processor when coding rule and program running and concrete process ID are irrelevant, have guaranteed the portability of program.

Among Fig. 1, resource management module is finished the function of relay resource centralized management, and Service Processing Module then is application and the user who uses relay resource.Deposited all relaying traffic resources of switching system in the resource allocation table of the resource management module among Fig. 1, and each relay resource has been distributed unique resource number.Service Processing Module has n, each Service Processing Module all has a module id unique in switching system separately, this module id can be added numbering by the sign of Service Processing Module type and form, the sign difference of wherein different Service Processing Module types, numbering can be when the Service Processing Module initialization, specify a current number unique in the Service Processing Module of same type by system dynamics, for example a kind of Service Processing Module type is M among Fig. 1, then when all Service Processing Modules behind system initialization, module id is M1, M2 ..., Mn.

Please in the lump with reference to figure 2, when Service Processing Module M2 needs the relaying traffic resource, distribute relay resource to the resource management module application, resource management module is selected available relay resource R2 according to certain system of selection in resource allocation table (system of selection can determine to realize whether the use of traffic resource is the load sharing mode, such as the selected number of times of noting each resource when the Resources allocation, when distributing new resources, need just in available resources, pick out the resource of choosing least number of times, it is dispensed), resource management module will apply for that the Service Processing Module sign M2 of this resource deposits in the resource allocation table corresponding to resource number R2, make relay resource R2 be returned the relay resource R2 of distribution for its use to Service Processing Module at last by sub-distribution again.

Service Processing Module M2 discharges relay resource R2 to the resource management module application, the resource processing module is according to the preservation record of resource allocation table, judge corresponding to the module id M2 of resource number R2 consistent with the module id M2 of the Service Processing Module of application release relay resource R2, then allow to discharge, module id M2 with resource number R2 correspondence in resource allocation table empties, and resource R2 can be assigned with once more.

If Service Processing Module M1 discharges relay resource R2 to the resource management module application, the resource processing module is according to the preservation record of resource allocation table, it is inconsistent with the module id M1 of the Service Processing Module of application release relay resource R2 to judge the module id M2 that deposits corresponding to resource number R2, then refusal discharges, and returns the result that refusal discharges to module M1.This method has prevented that effectively resource is by the generation of the situation of the Service Processing Module of this resource of unoccupied release.
