METHOD AND SYSTEM FOR IMPLEMENTATION OF SBLP FOR A WLAN-GSM/3G INTEGRATED SYSTEM

摘要

Packet data gateway (PDG) in an integrated WLAN - GSM/3G core network, is dis-closed 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 deci-sion function (PDF), a translating unit (TLT). The packet data gateway engages in a ser-vice 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 Func-tion (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.
