  • Patent number: 9706466
    Abstract: The present invention relates to a method for localization of peer-to-peer packet data traffic in a mobile network comprising a core network and at least one radio access network (RAN). The method comprises obtaining data traffic information for a packet data connection between two peers located in the RAN and where the connection is passing through a packet gateway node P-GW in the core network. If it is determined that the packet data connection is carrying peer-to-peer traffic, the PG-W requests localization policy information from a policy control function entity PCRF. The PCRF returns localization policy information related to the two peers and if localization is permitted, the P-GW requests a mobile management function entity to move the data traffic from the existing packet data connection to another packet data connection passing through another (local) packet gateway node L-GW which could be located in the same RAN as the peers.
