Abstract: A digital content provider, representing an author, provides copyright-protected digital content data and a metadata file appended to it for the electronic distribution of the digital content over a network. The electronic distribution metadata describes various data about the digital content such as the title, the author, the content provider, the royalty, and the redistribution parameters. A primary content receiver receiving the digital content and the metadata, generates and transmits a notice of completion based on the metadata parameters. Upon receipt, an electronic distribution management system within a service provider (xSP) provides fee assessment and proceeds distribution services.

Abstract: A NSP network is disclosed for providing a platform service for providing data communication security in an IP-based communications network. The platform service includes connections to various private networks, a subscriber data management unit for managing information about the mobile terminals using the network, and a platform unit. The platform unit determines from the subscriber data management unit the status of the mobile terminals requesting connections to private networks and the status of the mobile terminals for which private networks target for connection. The platform unit includes applications for querying the subscriber data management unit for subscriber status, applications to command the transmission of authorization data, and applications to provide secure virtual private network communication lines for connecting the mobile terminals and the private networks.
