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).
