Negotiation method and system provided by cross-domain service

Abstract

The invention relates to a negotiation method and a system provided by cross-domain service. The method is used to satisfy the need to provide cross-domain service among service platforms of cable operators, and concretely comprises negotiation on service supporting capability and negotiation on reserved resources. The negotiation on service-supporting capability comprises that: a session controller of a self domain receives a service request and forwards the service request to a session controller of an exotic domain which a service belongs to if judging the service is an exotic-domain service; the exotic domain gets a service-supporting capability list and corresponding service description information according to the service-supporting capability of a service server and network of the domain, and returns the list and the information to the session controller of the self domain; the session controller of the self domain decides that the capability with the fewest needed resources isa final service-supporting capability according to the intersection of the service-supporting capabilities of the self domain and the exotic domain, as well as the quantity of needed resources. During the negotiation on reserved resources, resource managers of the self domain and the exotic domain independently decide the amount of resource reservation according to relevant index parameters, and both the self domain and the exotic domain need to perform resource reservation.

Description

technical field [0001] The invention relates to the technical field of service operation support of a radio and television network, in particular to a negotiation method and system for providing cross-domain services. Background technique [0002] With the development of network convergence and information technology, cable operators have begun to open their network capabilities and service capabilities to the outside world by building an open service platform, supporting various types of terminal access methods, and supporting service sharing and cooperation among operators. Users provide more personalized services to improve their business support and operation capabilities. [0003] In the present invention, a domain refers to a management domain distinguished by a cable operator, and the management domains are connected through a metropolitan backbone network and a provincial backbone network. In the present invention, the cross-domain service means that users belonging...

Problems solved by technology

However, the scheme given by the IMS specification and the scheme of the patent "a method for negotiating service support capabilities" are still mainly aimed at the negotiation of the media parameter capabilities of the calling and called terminals. Both perform resource reservation. During the peak period of session negotiation, it is easy to cause excessive resource reservation and result in session negotiation failure.

[0008] Therefore, the existing negotiation method for cross-domain service provision cannot meet the requirements for cross-domain service provision between service platforms of cable operators
