Claim:
A method of reducing a number of page messages transmitted by a last registered mobile switching center (MSC) of a mobile communications device to one or more MSCs that border the last registered MSC, the method comprising the steps of: receiving an Inter System Page (ISPAGE) message from the last registered MSC to transmit a page message to the mobile communications device; retrieving a stored record of a time of a last seen activity of the mobile communications device, wherein the time of the last seen activity of the mobile communications device is stored regardless of a registration status of the mobile communications device; determining a time difference between an arrival time of the ISPAGE message and the time of the last seen activity of the mobile communications device; and dropping the ISPAGE message if the time difference between the arrival time of the ISPAGE message and the time of the last seen activity of the mobile communications device exceeds an optimum time cutoff value.
