METHOD AND SYSTEM FOR SUBSCRIBING TO SERVICES VIA EXTENDED UPNP STANDARD AND NASS TISPAN AUTHENTICATION

摘要

The present invention relates to a subscription method and system providing a modification of the UPnP standard, which by means of TISPAN delegated NASS authentication allows a user to play contents provided by a service provider via subscription by means of a control point which can be any consumer electronic device of the user. The modification of the standard is based on adding a field called 'subscriptionURL' and a variable called 'subscriptionStatus'. These modifications, the association established by the TISPAN CLF module between the user IP and the user IMSI and the implementation of a UPnP device in the user equipment, allow subscribing to the services provided by several service providers.
