Abstract
There is disclosed a system and method for over the air (OTA) activation of a mobile station in a wireless telecommunications network. During activation, a network OTA processor requests the data configuration of the mobile station. The mobile station may issue a challenge the OTA processor and in so doing transmits a challenge message including certain mobile station parameters and a code lock indicator to the OTA processor. The OTA activation processor determines if a new or first code lock parameter has been forwarded to the OTA activation processor by the network for the code lock indicator. If so, the OTA activation processor includes the first code lock parameter in a challenge message forwarded to the authentication center for processing a response to be validated by the mobile station. If not, the OTA activator forwards the challenge message to the home location register that has previously stored the code lock parameter. The home location register substitutes the stored code lock parameter for the code lock indicator and forwards the challenge message so revised to the authentication center for processing. The authentication center uses a code lock parameter comprising one…
