Embodiment
Below in conjunction with accompanying drawing the method for the invention is described in further detail.
The method of the invention is based on comprehensive, the network platform system that standard-sized sheet is put that multiple business such as speech, data, multimedia can be provided simultaneously, this network platform system can provide new business fast, set foot in frontier, has access capability and the high reliability and the fail safe of package.
The method of the invention adopts middleware CORBA technology, and structure Parlay interface API (ApplicationProgramming Interface, API) cooperates with business device so that new integrated network business to be provided by open api interface.Professional towards the terminal use can be traditional PSTN user, also can be IP user's (as IP phone, personal computer, multimedia terminal equipment etc.), between the two can intercommunication.
As shown in Figure 1, the user must transfer to a service code in order to obtain specific value-added service service.For example, by a super prefix that the whole nation is unified, the user can receive a tame enterprise on the geographical position from own nearest after-sale service site, in this example, service code is included in several bit digital of beginning of unified number, has only and just can carry out concrete professional selection and definite after Softswitch receives these several bit digital." user makes a call " in the flow chart represented this process.
In aforesaid example, after Softswitch receives unified number, it is selected and definite required business according to service code wherein, with regard to content of the present invention, be that Softswitch identifies a specific value-added service calling, and determine that the business that this calling is asked should be provided by corresponding business equipment by Parlay API, Softswitch can translate those numerals of service code back in the unified number, to obtain further information." Softswitch processing call request " in the flow chart represented this process, judges and selects " whether call out the value-added service of being asked provides by Parlay API " then to emphasize the identification of Softswitch to service request.Can know that from flow chart when judging that the result who selects is "Yes", flow process will be proceeded down according to the step of the method for the invention.And when the result is "No", flow process can enter " Softswitch continues to handle this calling by other flow process " this step, because the type of calling out is various, as at the calling of supplementary service, at calling of intelligent network business or the like, after judging that the result who selects is "No", Softswitch can continue to handle and proceed by other flow process to calling out, and the details of these flow processs and content of the present invention are irrelevant, give recapitulative explanation herein to keep the integrality of whole flow process.
Softswitch sends the result to business device by Parlay API after call request is handled, and is controlled by the business that business device is asked providing.And Parlay API is exactly the interface between Softswitch and the business device." sending request to business device " in the flow chart represented this process.
After business device receives the service request of Softswitch, will carry out the correspondent service logic program, to fulfil its control responsibility to institute's requested service.The implementation of service logic program is various, its complexity also is different, carry out repeatedly mutual with Softswitch possibly as business device and just can finish the business service of being asked, perhaps business device will be controlled media server and give user's playback, finishes corresponding operation with the prompting user.But these details are all irrelevant with content of the present invention, so what emphasized in the flow chart is a significant process that constitutes the method for the invention, rather than this process specific implementation how." business device execution service logic program " in the flow chart has represented this process.
When business service is finished, after user's on-hook, whole flow process finishes.
One of embodiment that adopts the method for the invention is as follows:
The terminal use dials the service code (as 300) of a value-added service service;
Softswitch receives this call request;
The Softswitch Query Database, and confirm that the business that this calling is asked is the value-added service that is provided by a business device by Parlay interface API;
Softswitch sends to a definite business device with the mode of this service request with Parlay interface API by CORBA;
Described business device is confirmed after the service request from user, calls the correspondent service logic program to carry out the business of user's request.If business device according to the requirement of business also needs and user carry out alternately, then this reciprocal process also will be carried out (inputing card number and password etc. as the prompting user);
Business device is undertaken finishing every function of the required business of user jointly, until the end of business service alternately by CORBA and Softswitch in the mode of Parlay interface API.
As shown in Figure 2, core concept of the present invention is utilized middleware Technology (CORBA) structure Parlay interface API exactly, and the api interface by this opening cooperates with business device so that new integrated network business to be provided.Therefore, this has been mainly concerned with Softswitch and business device, Parlay API is the interface between them, middleware is then finished the Parlay interface function of Softswitch and the agreement of business device is connected, and realizes that business device and Parlay interface function can be in the interoperability on heterogeneous networks, the heterogeneous platform.Among Fig. 2, the Parlay service end is the part of Softswitch, is also referred to as the Parlay gateway.Its is internally undertaken alternately by internal agreement with message control module of Softswitch, and is external then the Parlay interface API of standard is provided, and the confession business device calls.Business device can be provided by third party's stand alone software merchant, wherein should comprise the calling function of Parlay interface API, brings in expression with Parlay client among Fig. 2.Like this, by the api interface of opening of standard is provided to the third party, making it possible to provides professional by the third party, has embodied major technique characteristics of next generation network.What represent among Fig. 2 is a kind of situation in several structures, such as, also having a kind of structure is that the Parlay service end is independent of outside the Softswitch, certainly for business device, these details are unimportant, the just API of standard that business device is faced.No matter adopt which kind of structure, all be the equivalent transformation of the method for the invention, belong to the disclosed scope of the present invention.
The specific implementation of open service interface API should be diversified, and what the present invention relates to is the parlay interface, and as standard, it is well-known.The target of Parlay provides the cover DLL (dynamic link library) expanded open, that be independent of network and technology, realization is carried out safe open visit to the existing communication network, thereby establishes a kind of mode standardized, abstract, that in most of the cases can control network simply.Simultaneously, by the continuous expansion of docking port, can also solve evolution, fusion and the development problem of network.
According to the difference of function, the Parlay interface can be divided into several big classes:
The frame structure interface
Business interface
The public administration interface
Wherein, business interface is the core of Parlay interface, comprises again:
The call treatment business interface
The universal information business interface
The mobility service interface
The connectivity management business interface
And can be divided into as the call treatment business interface of business interface main body:
General service interface
Generalized calls control business interface
Multi-Way Calling control business interface
Multimedia call control business interface
Conference Calling control business interface
Common user interactive service interface
Calling party's interactive service interface
All Parlay api interfaces all are the requirements according to object-oriented method, with UML (Unified ModelingLanguage, UML) definition is described from class (Class), method (Method), parameter (Parameter) and four aspects of state model (State Model) respectively.
As shown in Figure 3; this is a kind of of soft switch service overall construction drawing; business device has partly been enumerated the example of several application among Fig. 3; be telecom operation back-up system (OSS; Operation Support System), network attached storage (NAS; Network Attached Storage), e-mail server (Email Server), message server (MessageServer) and (UMS of unified message system; Unified Message System), these should not be considered to the restriction to the method for the invention protection range.For example, other also can comprise numerous business such as unified personal number, internet call wait, click to dial, Web800.
More than the present invention is had been described in detail, specific descriptions wherein should not be considered to be limitation of the scope of the invention.Parlay API provides wide application prospect for the development of next generation network, and it will bring into play positive effect in the application in each field such as wire communication, wireless telecommunications, ecommerce, bank, enterprise, communications and transportation.
