Claims
- 1. A telecommunication terminal comprising:a smart card providing at least one application, means of access to the card by a telecommunication network, means of access to the card from a microcomputer processing unit, and means for managing the accesses from the telecommunication network and/or the microcomputer which: operates in a first operating mode to keep the two access means active, to change to a blocking mode to momentarily block one of the means of access to the card from the microcomputer or from the network while leaving the other access open, and to put on stand-by commands arriving through the blocked access means; and operates in a second operating mode to temporarily deactivate one of the access means, so that the terminal functions exclusively in a smart card read mode or exclusively in a telecommunication terminal mode.
- 2. A telecommunication terminal according to claim 1, wherein said access means comprise means for interpreting a command sent from at least one of the microcomputer and the network, for causing the terminal to execute those commands which can be executed by the terminal and for transmitting to the card those commands which can be executed by the card.
- 3. A telecommunication terminal according to claim 1, wherein the access management means keeps the two access means active and puts on standby the commands arriving through the network access means when the microcomputer requests access for an application different from one which is able to be used by the network.
- 4. A telecommunication terminal according to claim 1 wherein the access management means temporarily deactivates the network access means when the microcomputer requests access to an application that is able to be used by the network.
- 5. A telecommunication terminal according to claim 1, wherein the means of managing accesses to the card include means for the logical blocking and unblocking of access to the card by the network which is activated by the terminal after reception of a blocking command sent by the microcomputer.
- 6. A telecommunication terminal according to claim 5, wherein the blocking means have a timeout, during which the terminal is able to receive one or more commands from the telecommunication network and to store said commands until unblocking.
- 7. A telecommunication terminal according to claim 6, wherein the duration of the timeout corresponds to the maximum period required by the card for executing a microcomputer application command.
- 8. A telecommunication terminal according to claim 1, wherein the means of managing access to the card include reversible means of changing to an exclusive card read mode in which the telecommunication terminal operating mode is deactivated, said changing means being activated by the terminal after reception of a read mode command.
- 9. A telecommunication terminal comprising:a smart card providing at least one application, means of access to the card by a telecommunication network, means of access to the card from a microcomputer processing unit, and means for managing the accesses from the telecommunication network and/or the microcomputer which temporarily deactivates the network access means when the microcomputer requests access to an application that is able to be used by the network.
- 10. A telecommunication terminal according to claim 9, wherein said access means comprise means for interpreting a command sent from at least one of the microcomputer and the network, for causing the terminal to execute those commands which can be executed by the terminal and for transmitting to the card those commands which can be executed by the card.
- 11. A method for managing access to a smart card in a telecommunication terminal by each of a telecommunication network and a microcomputer processing unit, comprising the following steps:operating in a first mode to momentarily block one of said telecommunication network and said microcomputer processing unit from access to the card, while maintaining communication with each of said telecommunication network and said microcomputer processing unit; and operating in a second alternative mode to temporarily deactivate communications with one of said telecommunication network and said microcomputer processing unit, so that the terminal functions exclusively in a smart card read mode or exclusively in a telecommunication terminal mode.
- 12. The method of claim 11, further including the step of storing commands in said terminal that are received from the blocked one of said telecommunication network and said microcomputer processing unit while operating in said first mode.
- 13. A method for managing access to a smart card in a telecommunication terminal in which each of a telecommunication network and a microcomputer can access at least one application stored on the smart card, comprising the step of temporarily deactivating access to the smart card by the telecommunication network when the microcomputer requests access to an application that is capable of being used by the network.
