Method for accessing at least one service and corresponding system
View Patent ↗The invention relates to a method for accessing at least one service. A host device is coupled to a chip. The chip stores data relating to at least one test Subscriber Identity Module (SIM) type application and/or data relating to at least one SIM type application. The host device sends to the chip a command for switching from a first application to a second application. The first application is either a test SIM type application or a SIM type application. The second application is either a SIM type application or a test SIM type application. And the chip carries out an activation of the second application and a de-activation of the first application. The invention also relates to a corresponding system for accessing at least one service.
1. A method for accessing at least one service, via a host device coupled to a chip, the chip storing data relating to at least one test Subscriber Identity Module (SIM) type application and/or data relating to at least one SIM type application,
comprising the following steps:
the host device sends to the chip a command for switching from a first application to a second application, the first application being either a test SIM type application or a SIM type application, the second application being either a SIM type application or a test SIM type application; and
the chip carries out an activation of the second application and a de-activation of the first application.
2. The method according to claim 1 , wherein a computer device is connected to the host device, and further including a step in which the computer device sends to the host device the command for switching from the first application to the second application.
3. The method according to claim 1 , wherein a computer device is connected to the host device, and further including steps in which the computer device modifies data relating to at least one SIM type application and/or data relating to at least one test SIM type application and sends, through the host device, to the chip at least one command for modifying a content of at least one file stored by the chip accompanied with modified data relating to at least one SIM type application and/or modified data relating to at least one test SIM type application, and the chip stores the modified data relating to at least one SIM type application and/or the modified data relating to at least one test SIM type application.
4. The method according to claim 1 , wherein a remote server is connected to the host device, and further including a step in which the remote server sends to the host device the command for switching from the first application to the second application.
5. The method according to claim 1 , wherein a remote server is connected to the host device, and further including steps in which the remote server modifies data relating to at least one SIM type application and/or data relating to at least one test SIM type application and sends, through the host device, to the chip at least one command for modifying a content of at least one file stored by the chip accompanied with modified data relating to at least one SIM type application and/or modified data relating to at least one test SIM type application, and the chip stores the modified data relating to at least one SIM type application and/or the modified data relating to at least one test SIM type application.
6. The method according to claim 1 , wherein, before de-activating the SIM type application or the test SIM type application, the chip stores non-executable data relating to the SIM type application or the test SIM type application respectively.
7. The method according to claim 6 , wherein the non-executable data relating to the SIM type application or the test SIM type application includes at least one piece of data that enables an entity to be authenticated to either at least one mobile radio-communication network or a test equipment simulating operation of at least one mobile radio-communication network.
8. The method according to claim 1 , wherein the command for switching from the first application to the second application includes a command using Application Protocol Data Unit.
9. The method according to claim 1 , wherein, once chip has activated the second application and de-activated the first application, the chip sends to the host device a command for re-initializing the chip.
10. A system for accessing at least one service, the system comprising a host device and a chip coupled to the host device, the chip comprising means for storing data relating to at least one test Subscriber Identity Module (SIM) type application and/or data relating to at least one SIM type application,
wherein the host device is configured to send to the chip a command for switching from a first application to a second application, the first application being either a test SIM type application or a SIM type application, the second application being either a SIM type application or a test SIM type application; and
wherein the chip is configured to carry out an activation of the second application and a de-activation of the first application.
