Core functionality in PSM is mapping of subscriber ID (SID) to the then current IP address or IP addresses, which enables policies to be defined per subscriber, even when IP addresses are dynamically assigned. This is done by integrating PSM with operations (OSS) and authentication systems like RADIUS, policy control (PCRF) and DHCP through standard interfaces. Now individual and personalized service plans can be implemented, managed and monitored. Standard PSM interfaces are also used to export billing and charging information to BSS and OCS.
