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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Mobile gateway selection using a direct connection between a PCRF node and a mobility management node","description":"There is provided mobile gateway selection performed by a PCRF node in communication with an MME node or an S4-SGSN.
