CALLER INFORMATION NOTIFICATION SYSTEM, CALLER INFORMATION NOTIFICATION DEVICE, AND CALLER INFORMATION NOTIFICATION METHOD

摘要

PROBLEM TO BE SOLVED: To minutely notify a user of caller information when an incoming call is received by telephone.

SOLUTION: A home gateway (HGW) 1 inquires of an application server 4 caller information with the telephone number of an origination source extracted from an incoming call as a key. The application server 4 transmits the caller information to display terminals 31, 32, 33 and a portable telephone terminal 34 and allows the terminals to display the caller information returned from the application server 4. Thus, a user is notified of minute information of the origination source when the incoming call is received by telephone.
