  • Method and apparatus for adapting policy control
    Patent number: 8718075
    Abstract: Method and network nodes for adapting policy control function, wherein a load of a first network entity on which a policy execution function like a policy and charging enforcement function (PCEF) or a bearer binding and event reporting function (BBERF) is located is monitored (S4) and policy decisions are adapted based on said load. Particularly, the load may be reported to (N) or determined by a second network entity on which a policy supervision function like a policy and charging rules function (PCRF) is located, and said second network entity adapts policy decisions based on said load. When making policy decisions, the load status of a network entity like a gateway may thus be taken into account in addition to other factors.
