Claim Text:
1. A method, comprising: simultaneously detecting, by a communication device, a plurality of proximity location tags, when the communication device is proximate to the plurality of proximity location tag, each of the plurality of proximity location tags comprising a proximity location key identifying a location of one of the plurality of proximity location tags; automatically adjusting, by the communication device, a radio frequency output of the communication device to limit a size of a radio frequency envelope of the communication device until a closest proximity location tag of the plurality of proximity location tags is detected; receiving, by the communication device, a proximity location key from the closest proximity location tag of the plurality of proximity location tags; embedding, by the communication device, the proximity location key of the closest proximity location tag in a message and forwarding the message to a Voice over Internet Protocol Position Center (VPC); querying, by the VPC, a location information server for location information associated with the proximity location key of the closest proximity location tag; providing, by the VPC, the location information to a receiver; when out of range of any proximity location tags, determining, by the communications device, that the location of the communications device is unknown until the communications device detects one or more proximity location tags.
