Abstract

A sponsored-call service feature enables callers to obtain network-provided telecommunication services toil-free or at a subsidized rate. The sponsored-call service permits a third party sponsor to convey commercial messages to and interact with a caller prior to the caller's access to the network-provided services. After the caller's interaction with the sponsor, the network gives the caller a sponsored-specified restricted access to the network-provided services.
