Problems solved by technology

[0006] 1. The bearer level division of QCI is too rough. For example, the bearer level can only be roughly divided according to the type of service. As a result, the DSCP configured on the PGW / SGW network element side is not flexible, and it cannot be flexibly configured according to user level / brand
[0007] 2. Since each network element device may be produced by different manufacturers, and there is no uniform configuration standard for QCI in the industry, it may lead to inconsistent DSCP between network element devices, and differential service processing of user data packets in the network inconsistent

Embodiment 1

[0051] Such as Figure 4 As shown, taking the establishment process of a packet data network as an example, when the first request message is a credit control request message, the first node is a PGW, and the first response message is a credit control response message.

[0052] Specifically, after the mobile management entity (Mobile Management Entity, MME) entity receives the ATTACH or PDN connection establishment request of the user UE:

[0053] 1) The MME entity first sends a Create Session Request message to the SGW entity;

[0054] 2) The SGW entity forwards the Create Session Request message to the PGW entity.

[0055] 3) The PGW entity initiates a Credit Control Request credit control request message to the PCRF entity, requesting authorization of the PCC rule.

[0056] 4) According to the user information contained in the Credit Control Request, the PCRF entity includes the authorized PCC rules and QoS information in the Credit Control Answer credit control response ...

Embodiment 2

[0060] Such as Figure 5 As shown, for the process of establishing a dedicated bearer initiated by the network side, when the second request message is a RAR message, the first node is a PGW.

[0061] Specifically, 1) The PCRF entity initiates the Re-Auth-Request re-authorization request message process to the PGW entity, and the message carries the IP quintuple information, PCC rules, and QoS information of the established service flow, and the QoS information includes its corresponding DSCP value.

[0062] 2) After receiving the Re-Auth-Request, the PGW entity performs the binding of the service flow and the bearer, and extracts the corresponding DSCP for configuration. If it is confirmed that a new bearer needs to be established, it initiates a Create Bearer Request to the SGW entity to create a bearer request message, the message carries the QoS information of the bearer, including the DSCP authorized and configured by the PCRF.

[0063] 3) The SGW entity forwards the Cr...

Abstract

The invention discloses a configuration method, device and system of DSCP information and relates to the technical field of communication, wherein the configuration method, device and system of the DSCP information is based on the strategy and charging control PCC framework and different DSCP values can be flexibly configured for different users according to the configuration method, device and system of the DSCP information. The configuration method comprises the following steps that after a first request message sent by a first node is received or before a second request message is sent to the first node, the corresponding DSCP information used for representing the priority of messages is searched according to user information contained in the request message, the found DSCP information is packaged into a first response message corresponding to the first request message or is packaged into the second request message, and the first response message is fed back to the first node, or the second request message is sent to the first node.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, device and system for configuring DSCP based on policy and charging control PCC framework. Background technique [0002] With the continuous emergence of new applications and new services on the IP network, new requirements are put forward for the service quality of the IP network. High requirements, if the message transmission delay is too long, it will be unacceptable to users (comparatively speaking, E-Mail and FTP services are not sensitive to time delay). In order to support services such as voice, video, and data with different service requirements, the network is required to be able to distinguish different communications, and then provide corresponding services for them. The best-effort service of the traditional IP network cannot identify and distinguish various communication types in the network, and the ability to distinguish communication typ...
