Remote smart card personnalization without third party

A method for personalizing a smart card coupled with a communication device of a user being a subscriber of a first telecommunication network and wishing to become a subscriber of a second telecommunication network, a first international identity and a first authentication key being stored in the smart card, the method comprising the following steps in an application server included in a second telecommunication network:

• receiving a message comprising the first international identity and the first authentication key from another application server included in the first telecommunication network, after said another application server has received a request of subscription change comprising an identifier of the second telecommunication network and established a secured session with the application server of the second telecommunication network identified by the identifier,
• allowing the smart card to use resources of the second telecommunication network being authenticated by means of the first international identity and the first authentication key,
• sending another message comprising a personalization command, an admin code, a second international identity and a second authentication key to the communication device, the smart card being able to interpret the personalization command to delete the first international identity and the first authentication key and replace them by the second international identity and the second authentication key if the admin code is valid.

An application server for personalizing a smart card coupled with a communication device of a user being a subscriber of a first telecommunication network and wishing to become a subscriber of a second telecommunication network, a first international identity and a first authentication key being stored in the smart card, the application server (AS) being included in the first telecommunication network and comprising:

• means (MM1) for receiving a request of subscription change comprising an identifier of the second telecommunication network,
• means (MM1) for establishing a secured session with a second application server of the second telecommunication network identified by the identifier, and
• means (MM1) for sending a message comprising the first international identity and the first authentication key to said second application server that allows the smart card to use resources of the second telecommunication network being authenticated by means of the first international identity and the first authentication key,
• in order that said second application server sends second message comprising a personalization command, an admin code, a second international identity and a second authentication key to the communication device, the smart card being able to interpret the personalization command to delete the first international identity and the first authentication key and replace them by the second international identity and the second authentication key if the admin code is valid.

• means for allowing the smart card to use resources of the second telecommunication network being authenticated by means of the first international identity and the first authentication key,
• means for sending a second message comprising a personalization command, an admin code, a second international identity and a second authentication key to the communication device, the smart card being able to interpret the personalization command to delete the first international identity and the first authentication key and replace them by the second international identity and the second authentication key if the admin code is valid.

A computer-implemented method executed in an application server for personalizing a smart card coupled with a communication device of a user being a subscriber of a first telecommunication network and wishing to become a subscriber of a second telecommunication network, a first international identity and a first authentication key being stored in the smart card, the application server being included in the first telecommunication network, said program including instructions which, when said program is executed in said application server, execute the following steps:

• receiving a request of subscription change comprising an identifier of the second telecommunication network,
• establishing a secured session with another second application server of the second telecommunication network identified by the identifier,
• sending a message comprising the first international identity and the first authentication key to said second application server that allows the smart card to use resources of the second telecommunication network being authenticated by means of the first international identity and the first authentication key,
• in order that said second application server sends a second message comprising a personalization command, an admin code, a second international identity and a second authentication key to the communication device, the smart card being able to interpret the personalization command to delete the first international identity and the first authentication key and replace them by the second international identity and the second authentication key if the admin code is valid.

A smart card coupled with a communication device of a user being a subscriber of a first telecommunication network and wishing to become a subscriber of a user being a subscriber of a first telecommunication network and wishing to become a subscriber of a second telecommunication network, a first international identity and a first authentication key being stored in the smart card, a first application server being included in the first telecommunication network and a second application server being included a second telecommunication network, the smart card comprising:

• means for receiving a message comprising a personalization command, an admin code, a second international identity and a second authentication key from the second application server,
• after that the second application server has received a message comprising the first international identity and the first authentication key from the first application server, said first application server having initially received a request of subscription change comprising an identifier of the second telecommunication network and has established a secured session with the second application server of the second telecommunication network identified by the identifier, and after that the second application server has allowed the smart card to use resources of the second telecommunication network being authenticated by means of the first international identity and the first authentication key,
• means for interpreting the personalization command to delete the first international identity and the first authentication key and replace them by the second international identity and the second authentication key if the admin code is valid.
