A data call control method for a mobile station includes detecting
reception of a Release order message from a corresponding base station
during a data call for a service option, determining if call retry
restriction is necessary on the basis of the received Release order
message, and restricting, if call retry restriction is necessary,
retrying of the data call for the service option for a retry delay
period. A device that implements such methods includes a radio frequency
unit and a control unit to restrict retrial of a data call during the
data call delay period.
