Embedded subscriber identity module including communication profiles

A system comprising:

• a communications terminal;
• an embedded subscriber identity module that co-operates with the communications terminal, the module comprising:
• a plurality of communication profiles, at least two of said communication profiles being active at the same time so as to allow the communications terminal to communicate with each mobile telephone network associated with said at least two active communication profiles;
• a receive module for receiving, from the communications terminal, a command that has one of the at least two active communication profiles as a destination, wherein the one of the at least two active communication profiles is referred to as the destination profile;
• and
• a determination module for determining the destination profile from among the at least two active communication profiles on the basis of one or more bits included in said command, wherein said command is an application protocol data unit (APDU) command, and wherein the destination profile identifier of the destination profile is included in a CLA class byte of the APDU command, the CLA class byte being modified by replacing one or more bits dedicated for identifying a logic channel with one or more bits indicative of the destination profile corresponding to the destination of the ADPU command;
• and
• at least one device comprising:
• a send module that sends the command to one of the at least two active communication profiles that are active at the same time in the embedded subscriber identity module, each active communication profile enabling the communications terminal to communicate with a respective mobile telephone network;
• and
• a processor module that, prior to sending the command, modifies the one or more bits of the CLA byte of the APDU command to indicate the destination profile.

A processing method implemented by an embedded subscriber identity module co-operating with a communications terminal, the method comprising-:

• maintaining at least two active communication profiles in the activated state at the same time, whereby each active communication profile enables the communications terminal to communicate with a respective mobile telephone network associated with said active communication profile;
• receiving, from the communications terminal, a command that has one of the at least two active communication profiles as a destination, wherein the one of the at least two active communication profiles is referred to as the destination profile;
• and
• determining the destination profile from among said at least two active communication profiles on the basis of one or more bits included in a CLA byte of said command, wherein said command is an application protocol data unit (APDU) command, and wherein the one or more bits are indicative of the destination profile, the CLA class byte being modified by replacing one or more bits dedicated for identifying a logic channel with the one or more bits indicative of the destination profile corresponding to the destination of the ADPU command.

A non-transitory computer readable data medium on which there is stored a computer program including instructions that, when executed by a processor of an embedded subscriber identity module, cause the embedded subscriber identity module to perform operations comprising:

• maintaining at least two active communication profiles in an activated state at the same time, whereby each active communication profile enables a communications terminal to communicate with a respective mobile telephone network associated with the active communication profile;
• receiving, from the communications terminal, a command that has one of the at least two active communication profiles as a destination, wherein the one of the at least two active communication profiles is referred to as the destination profile;
• and
• determining the destination profile from among the at least two active communication profiles on the basis of one or more bits indicative of the destination profile included in a CLA byte of the command, wherein said command is an application protocol data unit (APDU) command, the CLA class byte being modified by replacing one or more bits dedicated for identifying a logic channel with the one or more bytes indicative of the destination profile corresponding to the destination of the ADPU command.
