Abstract

Calls to a wireless telephone number that are to be redirected by a gateway switch to another number can be properly billed, even if the wireless telephone number is ported to another service provider by billing the wireless telephone number subscriber for the charge that would have been incurred by placing a call to the forwarded number from the mobile telephone located in its home service area.
