Abstract: A system comprising a secure element cooperating with a telecommunication terminal is provided. The secure element or the terminal comprises files in which MCC/MNC codes of MNOs are stored. The telecommunication terminal is configured to select the files in order to attach the terminal to the telecommunication network of a MNO. The secure element or the terminal also comprise a file, called National like network file, for storing national network codes (MCC/MNC) of networks of the country of the Home PLMN of the secure element. The terminal selects the National like network file in order to try to connect the terminal to one of the networks referenced in the National like network file. Other embodiments are disclosed.

Abstract: Provided is a method to operate a subscriber identification module connected to a communication equipment configured to operate in a cellular network and communicatively coupled with a remote server. The method includes receiving from the communication equipment an information element indicating a time range relating to a suspend time of the communication equipment, receiving from the remote server a target access time information element indicating an expected time for an access request from the subscriber identification module to the remote server, and determining a suspension time period considering the suspend time range. The method includes providing to the communication equipment the suspension time period, and in case after resuming from the suspension instructed by the communication equipment the accumulated duration of at least one successive time period derived from the suspension time period exceeds the target access time, sending a polling message.

Abstract: Provided is a method for attaching a terminal cooperating with a secure element to the network of a MNO of a visited country. The method includes steps of switching a set of files of said secure element to a new value, including a new SUPI, called entity support SUPI; Building at the level of said secure element an entity support SUCI; Routing an attachment request to said support entity with said entity support SUCI; Decrypting in said support entity said entity support SUCI back in said entity support SUPI; and Swapping said support entity SUPI to the SUPI corresponding to the MNO of the home country. If an authentication is performed that is positive, an attachment acknowledgement message is sent to connect said terminal to said network of said MNO of said visited country.

Abstract: The present disclosure relates to a method for sending a message from a remote server to a terminal, the remote server and the terminal sharing a secret key, the method comprising: i—Sending from the terminal to the remote server a first identity; ii—Retrieving at the remote server the first identity and retrieving the secret key based on the first identity; iii—At the remote server, choosing a random number and generating a second identity thanks to the first identity, the random number and the secret key; iv—At the remote server, generating a signature from the first identity, the message, a counter value, the random number and the secret key; v—At the remote server, generating a first response for the terminal, the first response being a concatenation of the message, a counter value, the signature and the random number, and ciphering the first response with the secret key and sending the first ciphered response to the terminal; vi—At the terminal, deciphering the first ciphered response with the secret

Abstract: Provided is a method for connecting a terminal cooperating with a secure element to a second network, the secure element having a subscription from a first network whilst the secure element is roaming on a third network, the secure element storing the PLMN code of the second network, called second PLMN code, and the PLMN code of the third network, called third PLMN code, the second PLMN code having a higher priority than the third PLMN code in the OPLMN roaming file, the second PLMN having no roaming agreement with the first network nor the third network, and the third network having a coverage that overlaps at least a part of the coverage of the second network, the method comprising, when it is detected that the second network has rejected the attachment request of the terminal.

Abstract: Provided is a method to operate a secure chip card for connecting to a user equipment operating in a cellular network comprising a plurality of network slices, wherein for at least one network slice a slice authentication server is operational, the secure chip card comprising a secured memory with at least one slice authentication application

Abstract: A method for updating a terminal comprising a secure element is provided by way of an Over-the-Air (OTA) platform. The OTA receives at least a location data reflecting the location of the terminal and a request for downloading a list of preferred networks in the terminal. Each of said preferred networks may be associated with its own target roaming quota usage, at least one weighting factor associated to a given list of the set may be updated as a result of an optimization function which aims at generating one weighting factor based on a target roaming quota usage associated to each preferred network of the given list. Other embodiments are disclosed.

Abstract: A method for detecting that a removable secure element has been temporarily disconnected from a first device includes: Providing by the secure element to the first device a first Temporal Global Identity; Entering the first device in the sleeping mode; If the secure element is inserted and used by a second device during the sleeping mode of the first device, replacing in the secure element the first Temporal Global Identity by a second Temporal Global Identity and providing the second Temporal Global Identity to the second device; When getting out from the sleeping mode by the first device, reading by the first device the Temporal Global Identity stored in the secure element; If the Temporal Global Identity read is not the same than the stored Temporal Global Identity, sending to an MNO server a message to indicate that the secure element has been used by another device.

Abstract: 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.
