Proximity location system and method thereof for locating a communications device
First Claim
1. A method for locating a communications device, the method comprising:
- transmitting data from the communications device to a receiver;
detecting a proximity location tag in a predetermined proximity of the communications device;
sending a proximity location key from the proximity location tag to the communications device;
embedding the proximity location key in a SIP-INVITE message and forwarding the SIP-INVITE message, via a call server, to a Voice over Internet Protocol Position Center (VPC) for processing;
querying, by the VPC, a location information server for location information associated with the proximity location key;
routing the data to the receiver based on the location information; and
providing the location information to the receiver.

Abstract
A proximity location system and method thereof for locating a communications device. A radio-frequency identification (RFID) proximity location tag is arranged in a proximity of the communications device and detected thereby. A proximity location key included in the RFID proximity location tag is acquired by the communications device and forwarded to a location information server. The location information is queried for location information associated with the proximity location key. Based on the location information, data transmitted by the communications device is routed to the appropriate receiver of the data. The location information is also provided to the receiver.
