Description

Semantic communication network capability service gateway component, network system and method for work

Technical field

The present invention relates to a kind of semantic communication network capability service gateway component, network system and method for work, belong to telecommunication service network technical field.

Background technology

Business intelligentization is one of next generation network (comprising 3G, NGN, 4G etc.) focus that technical development is paid close attention to.Intelligentized business platform can be caught the residing environmental information of user and personal attribute's data in real time according to user's request, carries out the intelligent reasoning based on business contexts, satisfies users ' individualized requirement.Business model will by present serve as the main business model that progressively carries out the transition to based on " machine-machine " of intelligent agent alternately with " people-people " and " people-machine ", intelligent agent can be understood user's demand, searches, makes up and carry out the business that satisfies condition then and be user's service.In order to realize this intelligence communication environment, the telecommunication network services ability is carried out semantization, make various communication network capability service can be automatically by machine or intelligent agent is understood and processing is the basis.

Following network will be the fusion of the network of a fusion, especially telecommunications network and the Internet.At present, at internet arena, Semantic Web and Semantic Web Services are becoming a hot research direction that has potentiality, researchs have been carried out now in a large number, the Automatic Combined of dynamically finding, serving, the execution monitoring of service etc. as the ontology describing framework (OWL-S) of Semantic Web Services, based on the service of body at Semantic Web Services technology itself.Semantic Web Technology makes the original static resource in the Internet (as the Web info web) have semanteme, can carry out intelligentized search and reasoning.Semantic Web Services (the Semantic Web Service) technology that mutually combines and produced as the clear and definite formalization normalized illustration-body (Ontology) of shared ideas model and Web service technology, allow user or intelligence software agency automatically to locate, select, use, make up, monitor network-based services, feasible service becomes machine understandable, and the interoperability of impelling the network service is to automation, intelligent direction development.

At present, Internet technology has begun by the grammer aspect to the semantic level transition.In order to make telecommunications network and the Internet on operation layer, realize merging completely, can solve collaborative work and the interoperability problem of telecommunication service in heterogeneous network at semantic level, must on semantic level, carry out research to the communication network capability service.

The telecommunication opening service architecture has become the inexorable trend of telecommunication service development, and telecommunication service will continue to develop towards open direction.Next generation network (comprising 3G, NGN, 4G etc.) is exactly a kind of network architecture that the comprehensive opening of multiple business such as voice, data and multimedia can be provided, can support fastext to dispose and the professional control of third party, and value-added service can be provided fast and neatly.In next generation network, in order to realize third party's business development, adopt open distributed interface, the ability of communication network is provided out in some way, as the Parlay/OSA API of 3GPP and Parlay Group proposition, the Parlay X interface of Parlay WebService and higher abstraction hierarchy.Wherein, in realization mechanism based on Web Service, Parlay Web Service gateway is published to the communication network capability service registration center (Web Services Registry) of Web service, its needed capability service is searched by the registration center that the application server of Parlay can arrive Web service as required, calls the respective service that the Parlay gateway provides according to the description of WSDL WSDL then.But these communication network capability service open interfaces of describing based on WSDL do not have the description of semantization, can not be understood by machine and handle automatically.And the communication network capability service of describing based on WSDL, can only support match query based on the grammer aspect of keyword, can't support service search and accurate coupling, thereby be difficult to support the telecommunication service of following intellectuality more and personalization based on the semantic level of body.
