MEANS AND METHOD FOR CONTROLLING SERVICE PROGRESSION BETWEEN DIFFERENT DOMAINS

摘要

At present, the existing mechanisms for authorising a user of a service network operator to access a service provided by a third party service provider are valid for most of the existing services based on a request and an answer, but for transactional services, those where a service delivery implies several transactions, the existing techniques present serious limitations for the operators to fully control the progression of services. To overcome this limitation, the invention provides means and methods to control the progression of a service, service which requires a plurality of transactions, at a first domain where the service has been authorised while the user is using said service provided by a second domain, as well as a verification mechanism for verifying the use of the service between the service network operator and the service provider.
