Embodiment Construction

[0075] The system for realizing data flow service quality and charging policy control includes local gateway and policy charging rule function (PCRF).

[0076] The local gateway is configured to notify the policy and charging rule function of the identifier of the offloaded data flow after determining the offloaded data flow to be transmitted locally;

[0077] The policy and charging rule function is used to provide the local gateway with a quality of service policy and / or a charging policy rule for the offloaded data flow.

[0078] The policy charging rule function is also used to establish a session association relationship between the connection access network session established by the local gateway and the access network session established by the core network gateway in the network connection of the same user; When the assigned QoS policy and / or charging policy rule changes, the updated QoS policy and / or accounting policy is issued to the core network gateway and the loc...

Abstract

The invention discloses a method and a system for controlling service quality and charging policies of data stream. The method comprises the following steps that: a local gateway informs a policy and charging rule function (PCRF) of an identifier of split-flow data stream after the split-flow data stream which is required to be transmitted locally is determined; and the PCRF provides rules of a service quality policy and/or a charging policy of the split-flow data stream for the local gateway. By the method, the service quality and charging policies of the data stream of the local gateway can be flexibly controlled, so that the service performance of the system is improved.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method and system for realizing data flow service quality and charging policy control. Background technique [0002] In order to maintain the competitiveness of the third-generation mobile communication system in the communication field, provide users with faster rate, lower delay, and more personalized mobile communication services, and at the same time reduce the operating costs of operators, the Third Generation Partnership Project (3rd Generation Partnership Project, 3GPP for short) standard working group is working on the research of Evolved Packet System (EPS for short). figure 1 A schematic diagram showing the structure of an evolved packet domain system, such as figure 1 As shown, the entire EPS system is divided into two parts, the wireless access network and the core network. The core network includes a Home Subscriber Server (HSS for short), a Mobility Managemen...
