Content delivery involves the transport of information from a
source (content provider) to its destination (customer). The
customer usually selects to receive content (such as travel
directions or flight status information). The service provider
may charge a fee for access or may receive a percentage of the
fee paid by the recipient to the content provider (royalty fee).
Some of the more popular content providers include mapping
companies (for directions), music, flight status, weather information,
and other real-time or near real–time information
sources. The actual information content is often provided
through an application service provider (ASP) and transferred
through an Internet portal (gateway). The ASP usually manages
and updates the content, and the wireless provider provides
the transport to the end customer.
