Method and system enabling prepaid service in an all-ip network

摘要

The invention relates to a system and method for enabling prepaid service in a packet-based communications system, in particular in an All-IP network which comprises one or more subscriber terminals. At least one subscriber database stores subscriber information including identification data of one or more server means, and the at least one server means stores prepaid accounts for subscribers. When a subscriber terminal is initiating the establishment of a connection to another network entity, the server means is adapted to transmit a subscriber-prepaid-account related value informing a control means on an available charge threshold value for the connection to be established.
