Abstract:
A method of registration control in a mobile communication system, comprising the steps of:(a) assigning a base station and a registration interval to a mobile terminal according to a system acquisition operation;(b) performing location registration at a timing determined from the registration interval;(c) calculating a velocity of the mobile terminal;(d) evaluating the assigned registration interval according to the calculated velocity, the step of evaluating comprising comparing the calculated velocity with a lower threshold and an upper threshold corresponding to the assigned registration level;(e) selecting and assigning a new registration interval corresponding to the calculated velocity if the assigned registration interval is inappropriate, comprising sub-steps of:increasing the assigned registration interval if the calculated velocity is less than the lower threshold; anddecreasing the assigned registration interval if the calculated velocity is greater than the upper threshold; and(f) performing location registration at a timing determined from the new registration interval.
