Definitions

  • This invention relates to a method of data transfer from a server to a mobile station. More specifically, the invention relates to a method for the server to personalize a subscriber identity module (SIM) of the mobile station that has been deployed in the field.
  • SIM subscriber identity module
  • SIM subscriber identity module
  • IMSI international mobile subscriber identity
  • Such personalization of an issued SIM is necessary, for example to fix an existing software bug in the SIM, to update the contents of the SIM, to load new applications on the SIM, etc.
  • There are several ways to carry out personalization of an issued SIM One way is for the subscriber to bring the SIM to the premises of a service provider where the SIM is removed from the mobile equipment and inserted into a card reader/writer of a programming system for programming by a trained service person to effect the personalization. Such a method is very inconvenient to the user, and is both labour and resource intensive for the service provider.
  • Another way for personalizing the SIM is via over-the-air (OTA) transfer of data from the server to the SIM using SMS.
  • OTA over-the-air
  • This method of "pushing.” data to the SIM is advantageous to the subscriber in that personalization can now be performed remotely without any inconvenience to the subscriber.
  • this method of personalization is nevertheless still “expensive" to the service provider since several short messages are required to personalize a single SIM.
  • To update a batch of SIMs a correspondingly large number of SMSs would be necessary. It is also possible that not all SMSs are safely delivered to the subscribers; some SMSs might be lost.
  • Another disadvantage associated with such a remote personalization method is the need for the short messages to be encrypted using transport keys. To do so, the service provider needs to provide a server that is able to store the transport keys of all the SIMs that it issues.
  • An improvement over the "push" mode of personalization is a "pull" mode.
  • the server does not initiate the transfer of data to the mobile station. Instead, the mobile station initiates the transfer of data. At the occurrence of a designated event, the mobile station sends a request for update to the server. If the server determines that there is an update for the mobile station, the server will send the updated data to the mobile station.
  • This mode of personalization requires that the mobile station check regularly with the server if there is an update for the mobile station. When there is no update, bandwidth needed for the sending of the requests is wasted.
  • a method for transferring data from a server to at least one mobile station includes the server first sending a notification to the mobile station for informing the mobile station that there is data to be transferred to the mobile station.
  • the mobile station receives the notification, the mobile station sends a request to the server for requesting the server to transfer data to the mobile station.
  • the server sends a response to the mobile station for transferring data to the mobile station.
  • the mobile station includes a mobile terminal or equipment, and a subscriber identity module (SIM) that is connectable to the mobile equipment. The data may thus be transferred to either the mobile equipment or the SIM.
  • SIM subscriber identity module
  • Transferring of data includes, but is not limited to, downloading of a new file and updating an existing file or configuration data. Downloading of a file may include the downloading of a script file to the SIM for personalization of the SIM.
  • the request and the response are sent by the mobile station and the server respectively using one of the protocols in the Internet Protocol suite. Some examples of the protocols of the IP suite include the Hypertext Transfer Protocol (HTTP), File Transfer Protocol (FTP), etc.
  • HTTP Hypertext Transfer Protocol
  • FTP File Transfer Protocol
  • each of the mobile station and the server includes a master key that is common to both the mobile station and the server.
  • the server when sending the notification generates a session key, encrypts the generated session key using the master key, and sends the notification that includes the encrypted session key to the mobile station.
  • the mobile station receives the notification, it decrypts the encrypted session key in the notification using the master key.
  • the mobile station next generates a transport key and encrypts the generated transport key using the session key from the server.
  • the mobile station sends the request that includes the encrypted transport key to the server.
  • the server decrypts the encrypted transport key using the session key it generated earlier.
  • the server next encrypts the data for transfer to the mobile station using the transport key; and sends a response that includes the encrypted data to the mobile station. In this manner, the transfer of data from the server to the particular mobile station is secured.
  • it is the SIM of the mobile station that receives the notification, sends the request and receives the response.
  • the master key is stored in the SIM. This master key may be common to two or more SIMs in a batch of SIMs. These two or more SIMs can thus be targeted for personalization by using the master key.
  • the notification may be a short message service - cell broadcast (SMS-CB) message.
