US Patent 9622032, titled "Method and system for monitoring a mobile station presence in a special area," was issued on April 11, 2017, from an application filed on June 12, 2015. The sole inventor is Carlos A. Pérez LaFuente. The patent was originally assigned to AFIRMA CONSULTING & TECHNOLOGIES SL, and is currently assigned to Avant Location Technologies LLC and AFIRMA CONSULTING & TECHNOLOGIES SL.

Abstract:
The patent describes a method for monitoring a mobile station's presence in a specific "special area." A radio communication defining device broadcasts a distinctive signal that outlines this special area. The mobile station processes received signals to identify if it is receiving this distinctive defining signal. If so, the mobile station sends an updating signal to a mobile telephone network. This network then routes the signal to special operating means, which adjust an operating parameter based on the mobile station's presence in the special area. A key aspect of the invention is that the special area is linked to the mobile station by transmitting "checking data" to the mobile station. This checking data is then used by the mobile station to determine if the received signal is indeed the distinctive defining signal for that special area. The same checking data is sent to all mobile stations whose presence in this special area is being monitored.

Independent Claims Overview:

• Independent Claim 1 (Method Claim): This claim describes a method for monitoring a mobile station's presence in a special area. It involves a radio communication defining device transmitting a distinctive signal that defines the special area. The mobile station observes and processes signals to identify this distinctive defining signal. Upon detection, the mobile station sends an updating signal to a mobile telephone network, which then uses "special operating means" to adjust an operating parameter based on the mobile station's presence. The method is characterized by associating the special area with the mobile station by transmitting "checking data" to the mobile station. This checking data enables the mobile station to determine if a received defining signal is distinctive for its associated special area, and the same checking data is provided to all monitored mobile stations for that area. [Claim 1]

• Independent Claim 13 (Mobile System Claim): This claim defines a mobile system for monitoring a mobile station's presence in a special area. The system includes "checking means" to detect the mobile station's presence, comprising a radio communication defining device that transmits a distinctive signal. The mobile station itself has "observing means" and "processing means" to identify the distinctive defining signal. The system also includes "transmission means" for sending an updating signal from the mobile station's processing means to "special operating means" within the mobile telephone network, which then adapt an operating parameter. The system is characterized by having "storing means" in the mobile station for the "checking data," which the processing means use to determine if a defining signal is distinctive for the special area. The same checking data is sent to any mobile station whose presence in this special area is monitored. [Claim 13]

• Independent Claim 16 (Server Claim): This claim describes a server for use in the mobile system. It is characterized by containing at least some of the "special operating means" as defined in Independent Claim 13. [Claim 16]

• Independent Claim 17 (Radio Communication Defining Device Claim): This claim describes a radio communication defining device. It is characterized by carrying out the method described in Independent Claim 1. [Claim 17]

• Independent Claim 19 (Mobile Station Claim): This claim describes a mobile station. It is characterized by being suitable to carry out the method described in Independent Claim 1. [Claim 19]
