Abstract: An integrated circuit card with a memory space includes memory space locations for storing user profile data of a plurality of user profiles. The memory space can be partitioned in segments of memory space locations. A segment map includes segment map memory locations with the memory space locations in the memory space coupled to respective segment map memory locations in the segment map. The memory space locations in the memory space can be allocated to the user profile data by recording in the respective segment map memory locations in the segment map the profile in the plurality of user profiles to which the memory space locations in the memory space are reserved.

Abstract: A method of managing an integrated circuit memory includes having an integrated circuit card with a memory space including memory space regions for storing user profile data. The memory space is partitioned into segments of memory space regions, where the segments of memory space regions includes allocated regions and empty regions. From the empty regions, the biggest empty region of the memory space is selected. The selected biggest empty region is widened by moving memory blocks positioned in a subset of allocated regions that are at boundaries of the selected biggest empty region into other available empty regions.

Abstract: A method for concealing a subscription identifier at a user equipment including a mobile equipment and an integrated circuit card storing the subscription identifier, the method including receiving a corresponding request by a server to provide a corresponding subscription identifier, performing an elliptical curve encryption of the subscription identifier generating a concealed subscription identifier, the concealing operation including the mobile equipment sending an identity retrieve command to the card, performing, before receiving the identity retrieve command at the card, a pre-calculation of the ephemeral key pair including an ephemeral private key and ephemeral public key and the shared secret key, and in response to the respective state of completion indicating that completion of the computation of a valid ephemeral key pair or shared secret key, storing the corresponding values of the ephemeral key pair and shared secret key in a table in a memory of the card.

Abstract: A method for transmitting an Internet Protocol (IP) data packet from a first device to a second device, includes: transmitting a message from the first device to a telephone number associated with the second device; receiving the message at the second device and, in response to the message, determining a first IP address of the first device and transmitting a first IP packet from the second device to the first IP address; receiving the first IP packet at the first device and determining a source IP address of the first IP packet; and transmitting a second IP packet from the first device to the source IP address of the first IP packet.

Abstract: A communication method includes receiving a first message of a Short Message Service containing a first command that requests execution of a proactive command. The first message is decrypted according to protocol SCP80 to extract the first command. The execution of the proactive command is requested in order to obtain a response to the proactive command. A second message of the Short Message Service is transmitted to the remote server and indicates that the response to the proactive command has been obtained. A third message of the Short Message Service is received and contains a second command from the remote server. The third message is decrypted according to the protocol SCP80. A response message is generated as a function of the response and encrypted according to the protocol SCP80 to generate a fourth message of the Short Message Service transmitted to the remote server.
