Abstract
A system and method with policy control function (PCF) for multimedia broadcast/multicast system (MBMS) services that includes a core network, one or more application servers, and one or more policy control functions (PCF). In one embodiment, the core network includes one or more gateway GPRS support nodes (GGSN). One of the application servers provides a MBMS service. At least one policy control function is operatively connected between each GGSN and application server. MBMS session request information is sent from the MBMS service server to the policy control function. The policy control function provides authorization information for a MBMS session to the GGSN.
