A method performed by a policy and charging rules function (PCRF) node for selecting an Online Charging System (OCS), the method comprising:
- receiving at said PCRF node, a session establishment request for a subscriber;
- selecting an OCS realm for said subscriber session based on, in order of priority:
- policy rules;
- subscriber attribute;
- or system preference;
- selecting an OCS host for said subscriber session based on, in order of priority:
- policy rules;
- subscriber attribute;
- or system preference;
- and
- creating an Sy session using the selected OCS realm and selected OCS host.
A tangible and non-transitory machine-readable storage medium encoded with instructions thereon for execution by a policy and charging rules function (PCRF) node, wherein the tangible and non-transitory machine-readable storage medium comprises instructions for:
- receiving at said PCRF node, a session establishment request for a subscriber (subscriber session);
- selecting an OCS realm for said subscriber session based on, in order of priority, policy rules, subscriber attribute or system preference;
- selecting an OCS host for said subscriber session based on, in order of priority, policy rules, subscriber attribute or system preference;
- and
- creating an Sy session using the selected OCS realm and selected OCS host.
A Policy and Charging Rules Function (PCRF) node for a 3GPP-compliant packet data network, the PCRF node configured to:
- receive at said PCRF node, a session establishment request for a subscriber (subscriber session);
- select an OCS realm for said subscriber session based on, in order of priority, policy rules, subscriber attribute or system preference;
- select an OCS host for said subscriber session based on, in order of priority, policy rules, subscriber attribute or system preference;
- and
- create an Sy session using the selected OCS realm and selected OCS host.
