Patent ID: 8255549

Claim:
A system comprising: a processing device for detecting a terminal device roaming in a communication zone of an access point; an aggregating device for aggregating a plurality of IP multimedia subsystem services supplied by a plurality of disparate service providers, the aggregating device producing aggregated IP multimedia subsystem services; a presentation device for presenting a web page to the terminal device showing the aggregated IP multimedia subsystem services, wherein the web page is presented to the terminal device when the terminal device is detected; and a communications device for receiving a selection from the terminal device of at least one of the aggregated IP multimedia subsystem services to identify a selected service, wherein the selected service is enabled for the terminal device by providing to the terminal device at least one IP multimedia subsystem client corresponding to the selected service, wherein the at least one IP multimedia subsystem client is configured for automatic removal from the terminal device responsive to expiration of the selected service, wherein the aggregating device temporarily enables the selected service for a time period, wherein the communications device establishes communications with the terminal device by way of the access point, wherein during the time period a quality of service associated with the selected service is negotiated between the plurality of disparate service providers and a provider associated with the access point, wherein the communications device transmits to the terminal device the at least one IP multimedia subsystem client corresponding to the selected service and authorizes the temporary enablement in response to a valid authentication of the terminal device, wherein the processing device detects the expiration of the selected service and submits a charge to an account associated with the terminal device according to the selected service, and wherein the charge is limited to use of the selected service by the terminal device.
