Patent ID: 7916732

Claim:
Packet data gateway in an integrated Wireless Local Access Network (WLAN) - Groupe Speciale Mobile/3rd Generation (GSM/3G) core network, comprising a router having a number of gateways which are associated with various Quality of Service (QoS) traffic properties, an interface to a WLAN network and an interface to a policy decision function, and a translating unit; the translating unit engaging in a service based local procedure in whereby a negotiated QoS property is received for a given session identifier as negotiated between a user entity, an Application Function, and a Policy Decision Function and whereby: the translating unit controls the router to distribute incoming packets according to the negotiated QoS property for the given session identifier; the router selectively discarding packets not being associated with a QoS class or forwarding data to a default gateway, and forwarding packets associated with a high QoS class to a given gateway providing a high QoS; wherein said translating unit receives packets tagged with Differentiated Services (Diffserv) Code Points on a bearer from the user entity and said router distributes the tagged packets to appropriate gateways by applying differentiated QoS according to the Diffserv Code Points; and wherein said translating unit is able to receive packets tagged with Diffserv Code Points on the bearer from the user entity and said router is able to distribute the tagged packets to appropriate gateways by applying differentiated QoS according to the Diffserv Code Points because said translating unit previously interfaced with the user entity and received a token that identified a service which a bearer request is to be used for and a Diffserv Code Point that identified a QoS, and then said translating unit interfaced with the policy decision function and received authorization for a given bearer and opened one of the gateways for the Diffserv Code Point.
