Augmented Location Information for Wireless Communication

摘要

An Augmented Information server enables inclusion of augmented location data, in relation to an emergency call, expanded beyond that which can be fit into a pre-determined fixed length ALI data response field. A specific type of URI (Uniform Resource Identifier) is included in the ALI data response field, addressing specific augmented location data maintained by the augmented information server, e.g., a map image file, building floor plan, etc. The Augmented Information URI addresses to information accessed by the Augmented Information Server, inserted into an ALI data response field. The augmented, extended or additional location information is stored at a particular web address accessed through a query to the Augmented Information server.

1. A method of obtaining augmented location information in relation to an incoming call, comprising:
querying an automatic location information (ALI) database for basic location information; receiving, in response to said ALI query, location information relating to a location of a caller, together with a universal resource indicator (URI) indicating an address of augmented location information relating to said location of said caller; initiating a universal resource indicator (URI) de-reference request to an augmented location information server; and receiving, in return to said URI de-reference request, augmented location information augmenting said location of said caller.
