Abstract

A cellular telephone maintains a screening list of calling party numbers, and specifies call handling therefor. A mobile switching center is responsive to selected types of the specified call handling. The call handling can depend on whether the call is local or non-local, which is affected by the location of the cellular telephone. The call handling can also depend on the time at which the call is made. A subscriber updates his or her screening list via personal computer, and transmits via a communication network the updated screening list to a message center which sends the updated screening list to the cellular telephone via wireless communication. A calling party number can be specified as a wildcard.
