Storing subscriber location indication at DNS, to enable location specific provision of internet content

摘要

Methods, apparatus, and software for accessing location based Internet services by automatically populating DNS tables with subscriber location information. The DNS tables are updated responsive to information provided on subscriber call set-up. The location may be derived directly for the content of the call set-up, or may be derived in conjunction with one or more pre-existing databases. Ideally the DNS entry is a mapping from IP address (or subnet address) to location, though a mapping from domain name to location will also be effective. When a location based service is requested by a subscriber, the requested service may interrogate the DNS table to retrieve the requesting user's location without requiring further subscriber intervention.
