PACKET USAGE AMOUNT CALCULATION DEVICE AND PACKET USAGE AMOUNT CALCULATION METHOD

摘要

Provided are a packet usage amount calculation device and a packet usage amount calculation method with which the usage amount of a local network can be calculated from the home network side when communication is performed using local-network-use subscriber information. A subscriber profile storage unit (101) in a proxy device (100) stores token information associated with local network subscriber information (local network numbers), and a SMS instruction unit (103) transmits tokens to the local network numbers. A connection reception unit (104) receives the token information and IP address information from a terminal device (400), and a usage amount calculation unit (105) calculates a usage amount on the basis of the IP address.
