Abstract
The PCRF Selection Function selects the PCRF for an IP-CAN session. In embodiments, the PCRF Selection Function is located in the HSS and/or the 3GPP AAA server. The PCRF Selection Function is only required to be located in the HSS if a Bearer Binding and Event Reporting Function (BBERF) is deployed in the serving gateway. In this case, the PCRF selection takes place at the time that the PDN Gateway is selected and returned by the HSS to the serving gateway over the HSS to MME interface (S6a).
Claims28
A system, comprising:
- a policy control rules function (PCRF) Selection Function module housed in a non-Diameter Routing Agent (DRA) element within a home subscriber server (HSS), wherein the PCRF Selection Function module is adapted to deliver PCRF information via a Sh interface;
- and
- a second PCRF Selection Function module housed in a 3GPP AAA server, wherein the PCRF Selection Function module and the second PCRF Selection Function module share a common state store.
A method, comprising:
- receiving a request for policy control rules function (PCRF) information by a PCRF Selection Function module housed in a non-Diameter Routing Agent (DRA) element within a home subscriber server (HSS);
- and
- delivering the requested PCRF information, wherein the PCRF Selection Function module is adapted to deliver the requested PCRF information via a Sh interface;
- wherein the receiving uses a second PCRF Selection Function module housed in a 3GPP AAA server, and the second PCRF Selection Function module and the PCRF Selection Function module share a common state store.
A non-transitory computer-readable medium containing instructions for controlling at least one processor by a method, comprising:
- receiving a request for policy control rules function (PCRF) information by a PCRF Selection Function module housed in a non-Diameter Routing Agent (DRA) within a home subscriber server (HSS) element;
- and
- delivering the requested PCRF information, wherein the PCRF Selection Function module is adapted to deliver the requested PCRF information via a Sh interface;
- wherein the receiving uses a second PCRF Selection Function module housed in a 3GPP AAA server, and the second PCRF Selection Function module and the PCRF Selection Function module share a common state store.
A non-transitory computer-readable medium containing instructions for controlling at least one processor by a method, comprising:
- receiving a request for policy control rules function (PCRF) information by a PCRF Selection Function module housed in a non-Diameter Routing Agent (DRA) element within a home subscriber server (HSS);
- and
- delivering the requested PCRF information, wherein the PCRF Selection Function module is adapted to deliver the requested PCRF information via a Sh interface;
- wherein the receiving uses a second PCRF Selection Function module housed in a 3GPP AAA server, and the second PCRF Selection Function module and the PCRF Selection Function module share a common state store.
