Abstract

The invention relates to a method and system for policy control in a data packet network comprising a user equipment, a gateway and a home policy control node. The method comprises the steps of establishing a session between the user equipment and an application function. Then a session identifier is generated by the user equipment, and the same session identifier is generated by the home policy control node. The user equipment requests bearer establishment from the data packet network and marks bearer establishment packets with said session identifier. The gateway derives a user equipment identifier from the bearer establishment packets and determines policy decisions based on the session identifier and the user equipment identifier. The user equipment marks data packets sent over the established bearer with the session identifier; and the gateway applies policy and charging information for the session to the marked data packets.

Description

technical field [0001] The present invention relates to methods and systems for policy control in data packet networks. Background technique [0002] In UMTS (Universal Mobile Telecommunications System) with a packet-switched core network, the services provided constitute an advantage over circuit-switched mobile telecommunications systems such as GSM (Global System for Mobile Communications). For example video or voice calls require guaranteed quality of service (QoS), while non-real-time packet data can be provided on a best-effort basis. Said advancement in the various offered services should be properly managed by the network, which was the subject of a standardization meeting. [0003] 3GPP (Three Generation Partnership Project) has implemented a Policy Control Architecture in Release 5 to allow Service Based Local Policing (SBLP) for the IP Multimedia Subsystem (IMS). Through SBLP, a control plane (eg, IMS) can authorize and control bearer traffic based on Session De...
