Patent ID: 8670375

Claim:
A tracking area setting apparatus comprising: one or more processors; wherein the one or more processors are configured to: measure a frequency of occurrence of a service request transmitted by a user equipment terminal to a cell where the user equipment terminal is located based on a paging channel transmitted in all cells belonging to a tracking area where the user equipment terminal is located and where an identifier of the tracking area is reported from each cell of the tracking area, the user equipment terminal being a target user equipment terminal to receive a call and updating location registration based on the reported identifier of the tracking area, the tracking area including one or more cells; measure a frequency of occurrence of the location registration; and make a first determination whether a number of the frequency of occurrence of the service request in a first cell is equal to or greater than a first threshold value based on the frequency of occurrence of the service request, separate, based on the first determination that the number of frequency of occurrence of the service request in the first cell is equal to or greater than the first threshold value, the first cell from the tracking area to which the first cell belongs, based on the first determination, select a second cell having a maximum frequency of updating the location registration among cells adjacent to the first cell, make a second determination whether the second cell is to be combined with the first cell into a same tracking area, select, based on the first determination that the number of frequency occurrence of the service request in the first cell is less than the first threshold value and less than a second threshold value which is less than the first threshold value, a second cell having a maximum frequency of updating the location registration among cells adjacent to the first cell, and make a third determination whether the second cell is to be combined with the first cell into a same tracking area.
