A method associated with one or more providers of presence related services in connection with the use of a mobile station (100, 200, 300) and at least a first radio communication defining device (105, 212, 212b, 305) that transmits a first distinctive defining signal (214, 214b) and a second radio communication defining device (105, 212, 212b, 305) that transmits a second distinctive defining signal (214, 214b), the first distinctive defining signal at least partly defines a first special area (104, 203, 203b, 304, 606, 608) by its coverage, the second distinctive defining signal at least partly defining a second special area (104, 203, 203b, 304, 606, 608) by its coverage, the method comprising: electronically storing in special operating means (600, 700) data capable of linking the mobile station to the first and second special areas, the data including a first checking data (408, 454, 650, 652, 654, 656, 660) of the first radio communication defining device, a second checking data (408, 454, 650. 652, 654, 656, 660) of the second radio communication defining device, and a mobile station identifier, transmitting via a mobile telephone network to the mobile station the first checking data, and transmitting via the mobile telephone network to the mobile station the second checking data, receiving at least one of (i) periodically, (ii) at times recent to when the mobile station enters into or exits from the first special area, (iii) when the mobile station remains in the first special area and (iv) when the mobile station remains outside the first special area from the mobile station via the mobile telephone network a first updating signal that identifies the mobile station's presence in at least the first special area, and receiving at least one of (i) periodically, (ii) at times recent to when the mobile station enters into or exits from the second special area, (iii) when the mobile station remains in the second special area and (iv) when the mobile station remains outside the second special area from the mobile station via the mobile telephone network a second updating signal that identifies the mobile station's presence in at least the second special area, deriving from the first updating signal by the special operating means that the mobile station is present in the first special area, and deriving from the second updating signal by the special operating means that the mobile station is present in the second special area; and enabling or disabling by use of the special operating means a presence related service (AAA, BBB, QQQ, RRR, YYY, ZZZ) based upon the mobile station's presence being identified in the first special area, and enabling or disabling by use of the special operating means a presence related service (AAA, BBB, QQQ, RRR, YYY, ZZZ) based upon the mobile station's presence being identified in the second special area. electronically storing in special operating means (600, 700) data capable of linking the mobile station to the first and second special areas, the data including a first checking data (408, 454, 650, 652, 654, 656, 660) of the first radio communication defining device, a second checking data (408, 454, 650. 652, 654, 656, 660) of the second radio communication defining device, and a mobile station identifier, transmitting via a mobile telephone network to the mobile station the first checking data, and transmitting via the mobile telephone network to the mobile station the second checking data, receiving at least one of (i) periodically, (ii) at times recent to when the mobile station enters into or exits from the first special area, (iii) when the mobile station remains in the first special area and (iv) when the mobile station remains outside the first special area from the mobile station via the mobile telephone network a first updating signal that identifies the mobile station's presence in at least the first special area, and receiving at least one of (i) periodically, (ii) at times recent to when the mobile station enters into or exits from the second special area, (iii) when the mobile station remains in the second special area and (iv) when the mobile station remains outside the second special area from the mobile station via the mobile telephone network a second updating signal that identifies the mobile station's presence in at least the second special area, deriving from the first updating signal by the special operating means that the mobile station is present in the first special area, and deriving from the second updating signal by the special operating means that the mobile station is present in the second special area; and enabling or disabling by use of the special operating means a presence related service (AAA, BBB, QQQ, RRR, YYY, ZZZ) based upon the mobile station's presence being identified in the first special area, and enabling or disabling by use of the special operating means a presence related service (AAA, BBB, QQQ, RRR, YYY, ZZZ) based upon the mobile station's presence being identified in the second special area.
