Patent ID: 8265046

Claim:
A method, comprising: (a) identifying an access point available for connection over an air interface by a radio transceiver mobile station; (b) making a secure connection to a gateway over the air interface via the access point; (c) using the secure connection, making a connection to a generic access network controller over the air interface; (d) making a request to register with the generic access controller; (e) receiving a request rejected message from the generic access controller; (f) receiving a rejection cause field from the message; (g) determining a connection status field from the rejection cause field of the message; (h) if the connection status field indicates the connection is to be released, releasing the connection to the generic access network controller and the security gateway; (i) if the connection status field indicates the connection is to be maintained, maintaining the connections to the generic access network controller and the security gateway; (j) waiting for an elapsed time; and (k) repeating steps (a)-(i), wherein (j) waiting for an elapsed time further comprises: receiving a timer value from the message; loading a timer TU 3902 with the timer value; and decrementing the timer until the timer reaches an end condition, wherein the loading of the timer TU 3902 with the timer value further comprises: generating a random number between zero and the timer value; adding the random number to the timer value to form a sum; and loading the timer TU 3902 with the sum.
