METHOD OF MANAGING THE CONNECTIVITY OF A SECURITY ELEMENT TO A CELLULAR TELECOMMUNICATIONS NETWORK
The invention concerns a method of managing the connectivity to a mobile telecommunications network of a SIM cooperating with an IoT Device. The method includes modifying a parameter of the SIM to temporarily prohibit it from connecting to the mobile telecommunications network during a certain period of time.
1 . A method of managing the connectivity to a mobile telecommunications network of a SIM cooperating with an IoT Device, said method comprising modifying a parameter of said SIM to temporarily prohibit it from connecting to said mobile telecommunications network during a certain period of time.
2 . Method according to claim 1 , wherein said parameter is the MCC/MNC of the network to which said SIM connects.
3 . Method according to claim 2 , wherein said MCC/MNC is set to 001/01.
4 . Method according to claim 2 , wherein said MCC/MNC is a different Mobile Operator code than a Home Network of the SIM.
5 . Method according to claim 1 , wherein said parameter is the ACC file (Access Control Class) of said SIM, said parameter being set to 0 so that the priority of said SIM to connect to said network is nil.
6 . Method according to claim 1 , wherein a Home Network code is stored in the FPLMN of said SIM so that said SIM no longer connects to its home network.
7 . Method according to claim 1 , the method is implemented by an applet installed in a security element that includes the SIM.
8 . Method according to claim 1 , the method is implemented by said mobile telecommunications network.
9 . Method according to claim 1 , wherein said period of time is random.
10 . Method according to claim 9 , wherein said random period of time is defined within a time interval.
11 . A SIM for cooperating with an IoT Device, wherein the SIM comprises an applet capable of triggering the suspension of the modification and/or modifying a parameter of said SIM to temporarily prohibit the SIM from connecting to a mobile telecommunications network.
12 . Element of a mobile telecommunications network, wherein the element comprises a unit configured to trigger the suspension of the modification and/or to modify a parameter of a SIM cooperating with an IoT Device, in order to temporarily prohibit the SIM from connecting to said mobile telecommunications network.
