The Network management equipment includes an input section for inputting a network resource required for a network service, which is provided through the communication network system in the form of real entity in a service equivalent to said network service being provided without using the communication network system; and a conversion section for converting to the network resource the real entity input from the input section, and creating policy data based on said network resource.

Abstract: An IP address recognizing unit determines whether or not an IP address of a mobile IP terminal whose charging information is to be processed is managed by a local station. If the IP address is not managed, a MobileIP-Server searching unit determines which station is the home station of the IP address. Then, a different station information transmission determining unit and a different station IP charging apparatus transmitting unit transmit the charging information to the apparatus that is a different station IP charging apparatus and the home station of the IP address. Additionally, a different station IP charging apparatus receiving unit receives the charging information of the IP address, and stores the charging information in a charging information database (for different station transmission) and manages the charging information.
