Abstract

Packet data gateway (PDG) in an integrated WLAN-GSM/3G core network, is disclosed comprising a router (R) having a number of gateways (Wi; OP INT 1, OP INT 2, INT DEFAULT) which are associated with various QoS traffic properties (BE, EF), an interface to a WLAN network (Wu) and an interface (Go) to a policy decision function (PDF), a translating unit (TLT). The packet data gateway engages in a service based local procedure (SBLP) whereby a negotiated QoS property is received for a given session identifier as negotiated between a user entity (UE), an Application Function (AF) and a Policy Decision Function (PDF). A WLAN user entity engaging with the PDG is defined. Moreover, a service based local policy procedure (SBLP) for a packet data gateway (PDG) and Service based local policy procedure for a dedicated gateway support node (GGSN) and a tunnel terminal gateway (TTG) is disclosed.
