Abstract:
1. In a communication system having a radio access network that interfaces between wireless client stations and a wireless carrier's core packet network, wherein the core packet network is in turn connected with a public packet network, and wherein content requests from the wireless client stations to content servers on the public packet network pass through the core packet network on their way, a method comprising: operating an intermediation system on the core packet network, wherein the content requests pass through the intermediation system on their way from the wireless client stations to the content servers; receiving into the intermediation system a given one of the content requests being transmitted from a given one of the client stations to a given one of the content servers, the content request defining a request for particular content and carrying a user-ID indicative of a user of the given client station; confirming, at the intermediation system, that the user has a right to access the requested content, and responsively inserting into the content request, at the intermediation system, an access-token indicative of the right; and sending the content request, including the access-token, along from the intermediation system to the content server, whereby the content server may use the access-token as proof that the user has the right to access the requested content, wherein the method further comprises generating the access-token at the intermediation system, wherein generating the access-token comprises encrypting one or more values, and wherein the one or more values includes a timestamp.
