Description
Technical field
The present invention relates to network communications technology field, particularly a kind of method that interconnects of the heterogeneous-network service towards semantic association, under the isomeric telecommunication network environment, by the open network professional ability with converge signaling, the service architecture of the equity that set up to distribute, the method that interconnects to the business of semanteme with seating surface.
Background technology
On the fusion basis of existing communication network and packet switched data network, formed the next generation network (Next-Generation Networks--NGN) that can transmit multiple medium such as speech, data.NGN is a network based on IP infrastructure and packet switch, and it has merged existing fixed, multiple access network such as mobile, wired and wireless.Can see that the fusion of network will make Network evolve to the complicated business epoch that future can spanning network from the professional epoch of single network list.That is to say that new form of service will occur: made up many basic business such as speech, Email, VoIP, web page browsing, mobile service etc.The fusion of network means that also the user can insert in every way.Therefore NGN will cross over a plurality of bearer networks and provide these abundant, personalized and specialized business for the user, business be provided at the boundary of having eliminated in logic between fixed network, mobile network, wireless network and the Internet.
The complicated business of spanning network provides has huge market potential and temptation beyond doubt, yet Opportunity coexists with challenge.One of challenge is how spanning network provides professional; Two of challenge is how to shorten the professional generation cycle, guarantees conveniently professional the generation.
In traditional telecommunication service generating mode, the processor of carrying out call processing software is integrated with the device height of employing circuit mode, thereby providing of new business needed the long cycle, in the face of the market of competing day by day seems unable to do what one wishes.The appearance of intelligent network technology makes service logic and switch realize separating, and makes the new business of spanning network generate still very difficulty but intelligent network depends on the characteristic of bearer network.Provide professional problem in order to solve spanning network, many methods are considered the interconnected of network levels, and just by setting up gateway or network processing node connects heterogeneous network, it is interconnected to make that Network is able to.Yet in these class methods, increasing of the number networks that connects along with needs will increase the quantity of gateway and corresponding network node, also make network design and the complexity of implementing interconnected aspect increase greatly, and expense is O (n
2) (wherein n is for needing interconnected the number networks).Therefore these class methods have limited the scale of network, poor expandability.At present, interconnected needs between field of telecommunications business and the business are write the nested script of new service logic, interconnected such as the Ring Back Tone service of one number service and developing from pas network, usually mode is exactly to write new service logic, Zhong be professional if needs are interconnected again, perhaps other kind service needed is interconnected, just needs to expand existing service logic or writes new service logic.Therefore this mode has limited the professional scale that interconnects, poor expandability equally.
This shows, for spanning network provides professional and shortens the professional generation cycle, guarantee conveniently professional the generation, satisfy the diversified demand of people to telecommunication service, be badly in need of to want a kind of new architecture and method generates quickly and easily, customization and management service, both made things convenient for the user also to make things convenient for the third party service provider.
Summary of the invention
One object of the present invention satisfies the not user's of access way of the same race demand with regard to providing the method that a kind of business that guarantees spanning network interconnects.
Another object of the present invention is exactly by heterogeneous network homogeneity, encapsulationization being realized the business of across a network interconnects.
Another object of the present invention is exactly not upset under the professional own service logic situation, and by adopting the mode of semantic association, the logic of setting up between the business element is nested, forms new business.
Another object of the present invention just provides a kind of " as required " (On-Demand) provides professional integrated services pattern.
The present invention is a next generation network, under the multiple Access Network integrated environment, generates based on the carrier class of open network professional ability is professional.
At this, a kind of method that interconnects towards the isomeric telecommunication network service of semantic association is proposed, this is that a kind of application level that can be supported in carries out the professional method that interconnects.Main thinking is opened the Network ability exactly, and converge by signaling in the middle of a kind of and controlling mechanism Network abilities that these are open, according to various new service logics they are integrated into new business again, the seamless user side that is delivered to smoothly.Converge signaling by a kind of suitable centre and converge different network capabilitiess, the method than the interconnected method of network level in the complexity aspect network design and the enforcement from O (n
2) be reduced to O (n) (wherein n is for needing interconnected the number networks) greatly.Therefore this method has adopted three topmost technological means: suitable middle signaling; Open network interface standard and open grid service architecture (OGSA).Simple respectively below the introduction:
By analyzing, the middle signaling that is fit to that is adopted is the conversation initialized protocol of being organized to set up by IETF (Session Initiation Protocol--SIP).SIP is the agreement that is used to set up, revise and stop the session between two or more participants.Session (Session) is the exchanges data between its participant.The real time data that session is transmitted comprises various forms such as voice, video, text.These different types of data are carried by various other agreements.Therefore SIP itself is independent of other agreement, provides professional but must cooperate with other agreement.Such as, SIP has been used to carry traditional calling processing signaling ISDN User Part.SIP is also by the session control signaling of 3GPP (The thirdGeneration Partnership Project) employing as IP-based core network.Therefore, under the IP infrastructure environment of NGN, these characteristics of SIP make it support converging of different business as a kind of different procotol of agreement carrying of centre.Thisly connect the mode of heterogeneous network, not only solved the problem of crossover heterogeneous networks, also make the complexity of network design and enforcement aspect be reduced to O (n) (wherein n is for needing interconnected the number networks) greatly by an intermediate protocol.
The open standard of the network capabilities of industry main flow is Parlay, JAIN etc. at present, and these standards are independent of signaling protocol, and wherein JAIN depends on Java language, and Parlay is independent of programming language and execution environment.The target of Parlay is to be a group interface (API) with network capabilities (being not only session control) is abstract widely, this group abstraction interface has masked bottom details such as procotol or signaling for the third party service provider, and can use and the Control Network resource in a kind of mode of standard.The appearance of Parlay API makes the development technique of a series of IT field also can be used for the exploitation of telecommunication service, and this has made things convenient for third-party business development undoubtedly, can accelerate professional generation.Solve the professional problem that does not rely on bearer network simultaneously, made heterogeneous network pass through the Parlay homogeneity.
The Network ability is come out by Parlay is open, and under the big distributed environment of NGN, each business element also needs to be managed and undertaken integratedly by different service logics, could generate new business quickly and easily.This thereon generates business (application) with distributed business integration environment for professional generation person or service provider with regard to an opening of needs.In several distributed computing technology of main flow, RMI needs communicating pair to possess the environment of JAVA, and CORBA and DCOM are not suitable under the Internet environment even the loosely-coupled distributed service the integration environment of the interior structure of the scope of bigger next generation network.As a kind of pattern of Distributed Calculation, Web Services technology be a kind of simple, based on the standard of Distributed Calculation that is used to describe isomery of Internet.And based on the open grid service architecture of grid and WebServices technology for the open service build environment that makes up on many bearer services platform, be a kind of good solution.Because the basic premise of OGSA is that all things all are expressed as grid service.OGSA has defined the standard mechanism that is used to generate, name and find the grid service example.The most important thing is that OGSA has defined the semanteme of grid service.The business model that OGSA proposes provides professional virtual and high-level business integration.These also are consistent with the service feature that NGN needs.Based on the open grid service architecture, carry out business integration by the semantic association of creating between the grid service, improved professional interconnect integrated scale and extensibility, the business that has embodied " as required " supplies a pattern.
Technical scheme
Parlay provides the series of standards interface, really network capabilities will be opened away by Parlay, in the method, needs the mapping between realization Parlay and the Session Initiation Protocol on the one hand; On the other hand, in order to be supported on the open grid plane, also need to realize the communication mechanism between Parlay and grid platform towards the business integration of semanteme.Therefore, this method mainly is divided into three links: the mapping between (1) SIP and the Parlay; (2) communication between Parlay and the grid platform; (3) integrated based on the business association of OGSA towards semanteme.
First link is that the ability of SIP is come out by this open standard opening of Parlay.Mapping is mainly carried out between the interface method of SIP entity and Parlay, is divided into address resolution and message maps.The SIP entity comprises SIP User Agent (UA) and SIP Servers.The SIP entity comes SIP entity of unique representative by SIP URL usually.Also define many address styles in the data definition of Parlay, wherein just comprised the address style of SIP.The SIP effective address character string that meets RFC 3261 is effectively same in Parlay.Address resolution is just passable as long as the address parameter among the Parlay API is corresponded to parameter field appropriate in the sip message.Such as, Parlay method routeReq (), originatingAddress parameter value wherein just should be mapped to the From territory of sip message head; Equally, the value of parametric t argetAddress should be mapped to the To territory of sip message head.In addition, in SIP, a Dialog (Call just) is represented by a CallID.A pair of signaling relation between two SIP UAs of its expression.So in SIP, a Multi-Party Conference comprises a plurality of Calls.Yet in Parlay, a Multi-Party Conference just only is equivalent to a Call.Parlay represents the related of a Call and an end subscriber with Callleg.In message maps, such as, Parlay is connected to a Call by method routeReq () with a Callleg, therefore correspondingly routeReq () is mapped as the INVITE of SIP, and the latter is used for setting up a Dialog.Again such as, our the INVITE method by SIP changes current Dialog attribute to realize method attachMedia () or the detachMedia () of Parlay.Message maps also depends on the role of SIP Server: UA, B2BUA (UA back-to-back), Redirect server, Proxy server or third party effector.Usually the rule of foundation as: (1) different Parlay incident can change the role of SIP Server; (2) the different role Parlay incident that can take different control modes to handle to receive.Such as, receive a following Parlay incident as a UA role's SIP Server: application/business wishes that it handles one during from calling that network is sent according to the mode of B2BUA, and it is B2BUA that SIPServer will change its role UA.
Second link is to set up communicating by letter between Parlay and grid platform, just wishes the open network capabilities that comes out of Parlay further by carrying out integrated towards semantic association in this distributed environment of grid platform.Concrete method is: set up a kind of communication mode of service-oriented between Parlay and grid platform, Parlay interface and Parlay service/application are encapsulated into grid service and are deployed on the grid platform.Be divided into three main modules: (1) modular converter mainly is that Parlay interface and service/application encapsulation are converted to the grid service that meets the OGSA standard, is called the Parlay grid service; (2) Registering modules can be registered in this module by the grid service that is converted to, and the searching of Parlay grid service of this module after supporting other grid service to these conversions; (3) Parlay access engine module is supported dynamically the obtaining of Parlay grid service visited the physics Parlay platform of bottom then.Owing to do not need to increase new middleware entity or increase new agreement, this link can guarantee higher communication efficiency.
The 3rd link is under grid environment to be related integrated towards semanteme of elementary cell with the grid service.Utilized the business model of OGSA definition, this model also provides professional virtual and high-level business integration on the semantic basis of definition grid service.Concrete method is to have defined some functional entitys, comprises service log-on, professional route, operation code, service management etc.These functional entitys to as if be all grid service of host with the grid environment, comprise the conversion of second link and be registered to Parlay grid service in the grid environment.In dynamic integrity, grid service can have access to different network capabilitiess by interconnected Parlay grid service.
The user is from any network insertion, own demand to business is proposed whenever and wherever possible, by the carrying of SIP to different network protocol, through of the mapping of first link to Parlay, and the communicating by letter of second link Parlay and grid platform, in the 3rd link, can under grid environment, press the grid service element of the integrated necessity of demand, then back transfer arrives user side again, and whole process is transparent to the user, because the user only is concerned about the business that needs whether can provide, and be indifferent to business and how to provide.
A kind of method that interconnects of the isomeric telecommunication network service towards semantic association, the Network ability is opened, and converge by signaling in the middle of a kind of and controlling mechanism Network abilities that these are open, according to certain new service logic they are integrated into new business again, the seamless user side that is delivered to has smoothly adopted three topmost technological means: suitable middle signaling SIP; Open network interface standard P arlay and open grid service architecture (OGSA), mainly divide three links to realize:
Mapping between first link: SIP and the Parlay;
Communication between second link: Parlay and the grid platform;
The 3rd link: the business association towards semanteme based on OGSA is integrated.
By adopting this middle signaling of SIP, utilize its characteristic that is fit to other procotol of carrying, can solve the problem of professional crossover heterogeneous networks.
By adopting the open network interface standard, the opening of Network ability to be come out, the business that can solve does not rely on the problem of bearer network, makes heterogeneous network pass through the Parlay homogeneity.
Based on the open grid service architecture, carry out business integration by the semantic association of creating between the grid service, can improve business interconnect integrated scale and extensibility, the business that embodies " as required " supplies a pattern.
First link mainly is that the ability of SIP is come out by this open standard opening of Parlay, and the mapping between SIP and the Parlay is mainly finished by address resolution and message maps between SIP entity and Parlay interface method.
In second link by setting up communicating by letter of Parlay and grid platform, Parlay can be opened the network capabilities that comes out and further be packaged into grid service, in this distributed environment of grid platform, carry out integrated towards semantic association, communication between Parlay and the grid platform is that the mode by a kind of service-oriented is encapsulated into grid service and is deployed to grid platform Parlay interface and Parlay service/application and sets up, do not need to increase new middleware entity or increase new agreement, thereby can guarantee higher communication efficiency.
The 3rd link is under grid environment to be related integrated towards semanteme of elementary cell with the grid service, and the business model of having utilized OGSA to provide needs the many functional entitys of definition, comprises service log-on, professional route, service management etc.
The user proposes own demand to business whenever and wherever possible from any network insertion, experiences first link and second link, can translate grid environment, business element is after the 3rd link is integrated by grid environment, and back transfer is to user side again, and whole process is transparent to the user.
Towards the method that interconnects of the isomeric telecommunication network service of semantic association, its step is as follows:
Step S1 realizes the mapping between SIP and the Parlay, comprises address resolution and message maps between SIP entity and the Parlay interface method, and the realization of this mapping is called the Parlay gateway, is deployed in the core network edge;

Step S3: under grid environment, grid service is carried out integratedly, comprise registration, search, route, management to business.
The advantage that has, characteristics or good effect
This method at first is by open network capabilities standard, by this standard the Network ability is opened, converge signaling by a kind of suitable centre again and converge different open network abilities, therefore than the interconnected method of network level in the complexity aspect network design and the enforcement from O (n
2) be reduced to O (n) (wherein n the number networks) greatly for need connecting.
Present heterogeneous-network service is interconnected to be to write a mutual service logic for new composite service, yet need add or existing business element withdraws from as new business element, all need remodify service logic.If there is new service needed interconnected, also need to write new service logic, so the maintenance of service logic is big.And employing is carried out instant business integration towards the model of semantic association by the semantic association between the grid service, has improved professional interconnect integrated scale and extensibility.
Network is by homogeneity and encapsulation, and topmost characteristics are exactly that opening, extensibility are strong.Relation between them is reciprocity, meets the structure of P2P, can solve the business nesting problem in the service conflict.If the professional interconnected relation of our definition " " operator representations, then Xia Mian formula can be represented the interconnected of business: service service=service, the interconnected business of remaining that obtains that is to say still to meet open, extendible characteristics in form.
What realize is the professional interconnected pattern of " as required ".Business can be carried out integrated at an easy rate according to demand and other business, comprise combination or separation.The process of business integration is not subjected to the influence in time place yet, can carry out whenever and wherever possible.
The research that at present grid is applied to the interconnected fusion of next generation network service field is still rare both at home and abroad.The present invention by between the suitable integrated grid service model of grid platform and grid service towards the associate feature of semanteme, the business under the field of telecommunications multi-access network of can solving the preferably problem that interconnects.
