Abstract
A 1xEVDO network includes an access terminal that generates an access terminal ID as a part of the call setup signals it generates when setting up a data call. In order to determine whether the user ID is authorized to access the 1xEVDO wireless data network, a AAA server is formed to include a table that identifies authorized access terminals, by access terminal ID, for access to the 1xEVDO wireless data packet network. In one embodiment of the present invention, the wireless access terminal also is formed to perform an algorithmic calculation upon a received random number and to produce the results to an access network controller. The AAA server, then, is formed to determine whether the results produced by the access terminal are correct. In one embodiment of the invention, the AAA server is formed to perform the same algorithmic calculation. In another embodiment of the invention, the AAA server is formed to compare the received results from the access terminal's algorithmic calculation to a value stored in memory.
