Abstract:
A method of managing mobile station operational parameters in a wireless communication network, comprising:transmitting a message from a network to a mobile station to indicate an initiation of an update of the mobile station operational parameters; and updating the mobile station operational parameters after completing a mutual authentication between the mobile station and the network, wherein the mutual authentication comprises generating a first random number at the network and transmitting the first random number to the mobile station, and generating a first authentication at the network utilizing the first random number; generating at the mobile station a second authentication utilizing the first random number received from the network and generating a second random number, said mobile station transmitting the second random number with the second authentication to the network and generating a third authentication utilizing the second random number; comparing the second authentication with the first authentication; generating at the network a fourth authentication utilizing the second random number from the mobile station; transmitting from the network the fourth authentication to the mobile station if the first authentication and the second authentication are equivalent; comparing the third authentication with the fourth authentication; and completing a mutual authentication if the third authentication and the fourth authentication are equivalent.
