ABSTRACT:
To effectively prevent information leakage from a communication node, such as a cellular phone. Not an actual communication-destination telephone number, but a telephone number code which is arbitrarily assigned corresponding to the actual communication-destination telephone number, and information required for telephone number selection are registered in an address book of a cellular phone2. An actual telephone number of each cellular phone2, a telephone number code of a communication destination thereof, and information of the communication destination are registered in an address book of an address management server4in association with one another. When a communication-source cellular phone2makes a call to a communication-destination cellular phone2, the actual communication-source telephone number and the communication-destination telephone number code are sent from the communication source to the address management server4, and a communication-destination telephone number is searched for to obtain the actual communication-destination telephone number. The obtained telephone number is used to connect a call path between the communication source and the communication destination.
