Abstract
A method and apparatus are provided for excluding ineffective Inter System Page (ISPAGE) attempts in a mobile switching center (MSC). The present invention involves determining a time difference between an arrival time of an ISPAGE message and a time of a last seen activity of a mobile communications device. The ISPAGE message is dropped if the time difference exceeds an optimum time cutoff value. Also, the present invention provides a technique for determining the optimal time cutoff value by determining the fraction of all ISPAGE messages that may be dropped, and the fraction of all ISPAGE messages that produce page respones that will be admitted as a function of the optimal cutoff time value.
