1. A method, comprising:
- detecting, by a communication device, a plurality of proximity location tags, 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;
detecting a closest proximity location tag of the plurality of proximity location tags;
receiving, by the communication device, the proximity location key from the closest proximity location tag;
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; and
as the communications device changes location, when the communications device senses that it is no longer in sufficient proximity to 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.

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.

12. A system, comprising:
-
a plurality of proximity location tags, 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; a communication device configured to; detect a closest proximity location tag of the plurality of proximity location tags, receive the proximity location key from the closest proximity location tag, embed the proximity location key of the closest proximity location tag in a message, and as the communications device changes location, when the communications device senses that it is no longer in sufficient proximity to any proximity location tags, the communications device is configured to determine that the location of the communications device is unknown until the communications device detects one or more proximity location tags; and a Voice over Internet Protocol Position Center (VPC) configured to receive the message from the communication device, query a location information server for location information associated with the proximity location key of the closest proximity location tag, and transmit the location information and to a receiver, wherein the location information comprises Master Street Address Guide (MSAG) valid location information, and the VPC is configured to extract the proximity location key from the message and to query the location information server for the MSAG-valid location information. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)

20. An apparatus, comprising:
-
a detector configured to; detect a plurality of proximity location tags when the apparatus is proximate to the plurality of proximity location tags, each of the plurality of proximity location tags comprising a proximity location key that identifies a location of one of the plurality of proximity location tags, detect a closest proximity location tag of the plurality of proximity location tags, and as the apparatus changes location, when the detector senses that the apparatus is no longer in sufficient proximity to any proximity location tags, the detector is configured to determine that the location of the apparatus is unknown until the detector detects one or more proximity location tags; an acquisition component configured to receive the proximity location key from the closest proximity location tag; and a transmitter configured to transmit a message comprising the proximity location key to a voice over internet protocol position center (VPC), wherein the location comprises Master Street Address Guide (MSAG) valid location information, and the VPC is configured to extract the proximity location key from the message and to query the location information server for the MSAG-valid location information.
