NOTIFICATION OF A CELLULAR USER'S CONNECTION TO THE CELLULAR NETWORK

摘要

A method by a cellular network for notifying a caller when a called user is connected to the cellular network includes the steps of storing a phone number associated with a caller that wants to be notified when a called user is connected to the cellular network, registering the called user with the cellular network when a communication device associated with the called user becomes active on the network, and notifying the caller indicating that the communication device is active on the network responsive to the step of registering by the called user.
