Abstract
A method of filtering and gating data flow in a QoS connection between a remote host and user equipment in a packet data network using policy control mechanisms includes a remote host initiating an application in an application server and a corresponding session between the remote host and the user equipment ('UE') via the application server. The UE requests, to a gateway support node ('GGSN') of the network, establishment of a network bearer service between the UE and the remote host. A corresponding policy control function ('PCF') in a policy server receives, from the application server, filtering data derived from session data received by the application server during the session. The GGSN interrogates the corresponding PCF in the policy server to initialize a gate using policy control filtering data at the GGSN. The gate then filters the data flow in the QoS connection according to the policy control filtering data.
