Abstract
A cellular phone includes a random number generator. When the cellular phone performs location registration operation, a time of executing location registration is determined by random numbers. Therefore, in a situation where a large number of cellular phones must perform location registration substantially simultaneously, an event where a large number of the location registration operations overlap with one another can be avoided. Hence, simultaneous concentration of loads on a network is eliminated, and stable communications between the cellular phones and an administrative server are maintained.
