"AIR ACTIVATION PROCESS FROM A MOBILE STATION PREVIOUSLY ACTIVATED IN A WIRELESS COMMUNICATION NETWORK AND AIR ACTIVATION SYSTEM FOR USE IN A WIRELESS TELECOMMUNICATIONS NETWORK TO ACTIVATE A PREVIOUSLY ACTIVATED MOBILE STATION". a system and process for air activation (OTA) of a previously activated mobile station (14) on a wireless telecommunications network is presented. During the new activation, a function processor requests the data configuration of the mobile station. The mobile station can issue a first challenge inquiry to the function processor (12) and in doing so transmit a question message that includes certain parameters from the mobile station to the function processor. The function processor then communicates this information to the network authentication center (22) which produces a query return message for certain parameters of the mobile station and transmits the query return message to the mobile station. The mobile station validates the return interrogation message and if validation is beneficial the mobile station completes the configuration transfer of data from the mobile station to the function processor. The authentication center uses one of the security locks Shared Secret Data Challenge (SSD_C) and Shared Secret Data Subsidy (SSD_S) not broadcast through radio waves in the generation of the return to interrogation message. The authentication center stores the SSD_C and SSD_SS for this purpose and is notified by the mobile station about which of these two parameters should be used by a Shared Secret Data Select (SSD_Select) parameter indicator sent by the mobile station as one of the parameters transmitted in the request for interrogation. The function processor then forwards new operating parameters to the mobile station and requests the mobile station to reset to these parameters. The mobile station can then issue a new interrogation to the function processor to reestablish where the second interrogation is handled by the network in a similar way to the first interrogation.
