US 9119030

US Patent 9119030, titled "Method and system for monitoring a mobile station presence in a special area," was issued to Avant Location Technologies LLC, with Carlos A. Perez Lafuente listed as the inventor. The application was filed on December 5, 2014, and the patent was granted on August 25, 2015.

Abstract:
The patent describes a method for monitoring the presence of a mobile station in at least one special area. A radio communication defining device repeatedly transmits a distinctive radio defining signal that outlines the special area by its coverage. The mobile station processes received signals to determine if it is receiving a defining signal and, more precisely, a distinctive one that defines the special area. The mobile station then sends an updating signal to a mobile telephone network, which routes it to special operating means that adjust the value of an operating parameter. A key characteristic is that the special area is linked to the mobile station by transmitting "checking data" to the mobile station. This checking data is used by the mobile station to determine if a received defining signal is distinctive and defines the associated special area, either alone or with other distinctive defining signals. The same checking data is sent to all mobile stations whose presence in that special area is being monitored.

Independent Claims Overview:

• Independent Claim 1 (Method): 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 if it's receiving such a distinctive defining signal. Upon detection, the mobile station sends an update to a mobile telephone network, which then uses special operating means to adjust an operating parameter based on the mobile station's presence in the special area. Crucially, the special area is associated with the mobile station by providing the mobile station with "checking data." This checking data is then used by the mobile station to determine if a received signal is the distinctive defining signal for that special area. The same checking data is provided to all mobile stations being monitored in that specific special area.

• Independent Claim 13 (Mobile System): This claim outlines a mobile system designed to monitor a mobile station's presence in a special area. The system includes checking means for detecting the mobile station's presence, which comprises at least one radio communication defining device transmitting a distinctive signal. The mobile station itself has observing means to detect signals and processing means to determine if a received signal is a distinctive defining signal. Transmission means are present to send an updating signal from the mobile station's processing means to special operating means within the mobile telephone network. These special operating means adapt an operating parameter based on the mobile station's presence. The system is characterized by storing means within the mobile station for holding "checking data," which the processing means use to identify distinctive defining signals. Similar to the method claim, the same checking data is sent to any mobile station monitored within that special area.

• Independent Claim 22 (Server): This claim defines a server characterized by containing at least some of the "special operating means" as described in the mobile system of the invention. The special operating means are responsible for adapting operating parameters based on the mobile station's presence in a special area.

• Independent Claim 23 (Radio Communication Defining Device): This claim specifies a radio communication defining device that is configured to carry out the method described in the invention. In a particular embodiment, this device is a wireless device with means to transmit a distinctive wireless signal defining the special area and means to obtain reliable information confirming its location within a predetermined environment.

• Independent Claim 25 (Mobile Station): This claim describes a mobile station that is suitable for carrying out the method of the invention.
