  • MOBILE GATEWAY SELECTION USING A DIRECT CONNECTION BETWEEN A PCRF NODE AND A MOBILITY MANAGEMENT NODE
    Publication number: 20150382386
    Abstract: There is provided mobile gateway selection performed by a PCRF node in communication with an MME node or an S4-SGSN. The mobile gateway selection is based on a direct MME/S4-SGSN-PCRF interface. A request message for a Packet Data Network Gateway Internet Protocol address to be used for establishing a session for a first user equipment is transmitted from the MME/S4-SGSN to a Policy and Charging Rules Function node through a direct MME/S4-SGSN-PCRF interface. The Policy and Charging Rules Function node determines a PDN GW IP address to be used for establishing the session based on policies for the first user equipment and transmits the PDN GW IP address through the direct MME/S4-SGSN-PCRF interface to the MME/S4-SGSN.
