Guidance information notification apparatus in communication network system, communication network system and guidance information notification method

摘要

There is provided a guidance information notification apparatus in a communication network system which enables improvement of convenience to a user by dispensing with a particular operation other than a normal origination operation required when a user obtains a guidance message in an understandable language such as a native language, with a terminal unit, and by enabling the user to receive support from a communication operator of the user's contract network even when a roaming service is provided. If an originator inputs a destination telephone number with a normal origination operation at a mobile telephone set 18, a guidance information notification apparatus 22-1 notifies guidance message information in a language associated with the origination telephone number to the origination mobile telephone set 18. Similarly, a guidance information notification apparatus 22-2 notifies guidance message information in the language associated with the destination telephone number to the destination fixed telephone set 20. Furthermore, a direction to process guidance message information is received from a switchboard 12 or 14, and the guidance message information is notified to the telephone set 18 or 20 in response to this direction.
