The PDSN also supports triggering of online charging via the policy interface. 3GPP Release 8 Gy interface as defined
in 32.299 is used for online charging.

sessions across multiple servers are achieved by using a round robin algorithm. Redundancy between servers can be
achieved by configuring multiple weighted sets of servers.
The configuration allows Policy support to be enabled on a per subscriber/APN basis.
