METHOD FOR ESTABLISHING COMMUNICATION CONNECTION

PROBLEM TO BE SOLVED: To connect a user with an arbitrary switchboard, regardless of the access identifier of the user by routing a call by referring to a concentrated data base. SOLUTION: A concentrated data base operates translation between an access identifier, such as the number and name of a called side or the other handle(for example, an electronic mail address) and a destination switchboard 2. This translation offers the identification of a port or port group at an incoming side, so that access from the destination switchboard 2 to a destination terminal 11 can be performed. In this case, the port is an exit (outlet) from the switchboard for transmitting a communication signal with a user. Thus, a call to a certain number can be connected with the subscriber of the arbitrary port of an arbitrary switchboard, including a port for offering a service to wireless equipment.
