Abstract: A method for obtaining capabilities of a Policy and Charging Enforcement Function (PCEF) includes these steps: a Policy Control and Charging Rules Function (PCRF) obtains capability information of the PCEF; and the PCRF performs processing according to the capability information. A PCRF is also disclosed. With the present disclosure, the PCEF reports its capabilities in advance so that the PCRF makes policy decisions for a service or subscribes to appropriate application events from the PCEF when it knows the capabilities of the PCEF. This avoids possible subscription errors and decision failures arising when the PCRF is unable to know the capabilities of the PCEF.
