Abstract:
A wireless communications network system for activating over the air (OTA) a mobile station, comprising:an over the air processor for activating the mobile station and for receiving from the mobile station a first challenge request message of the activation that includes certain mobile station parameters and a code lock indicator, the over the air processor determining if a first code lock parameter corresponding to the code lock indicator has been received from the network and and if so, the over the air processor replacing the code lock indicator with the first code lock parameter and forwarding the first challenge request message including the certain mobile station parameters and the first code lock parameter to the an authentication center, and, in the event the over the air processor has not received the code lock parameter, the over the air processor forwarding the first challenge request message including the certain mobile station parameters and the code lock indicator to a first predetermined node in the network;the first predetermined node upon receipt of the first challenge request message including the code lock indicator, replacing the code lock indicator with a stored code lock parameter stored in the predetermined node for the mobile station and corresponding to the code lock indicator, and the first predetermined node forwarding the first challenge request message including the certain mobile station parameters and the stored code lock parameter to the authentication center; and,the authentication center upon receipt of the first challenge request message using the certain mobile station parameters and a forwarded one of the first code lock parameter and stored code lock parameter to generate a return challenge response message and forwarding the return challenge response message to the over the air processor and onto the mobile station for validation.
