Problems solved by technology

For example, the maximum bandwidth of an activated PDP context is 128K. In the activated state, due to insufficient bandwidth resources, the SGSN initiates the PDP context modification process to reduce the maximum bandwidth to 32K. After a period of time, the bandwidth resources of the SGSN are no longer limited, but the SGSN does not Will actively initiate the PDP context modification process again, and the maximum bandwidth has been reduced to 32K, so the existing QoS parameter adjustment method cannot meet the user's service quality requirements to a greater extent

Embodiment Construction

[0020] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0021] In the method of the invention, each node device in the mobile packet network determines how to adjust the QoS parameter according to its own resource status and the record of the QoS parameter adjusted by itself as the initiator or receiver. Each node device in the mobile network includes UE, SGSN and GGSN and so on.

[0022] In the initial state, when the mobile network node device is successfully activated using the PDP context, an initial QoS parameter will be negotiated. When the mobile network resources are sufficient, the initial QoS parameter should be the QoS parameter requested by the UE and the user subscription QoS. The smaller one, and when the mobile network resources are insufficient, this initial QoS parameter should be smaller than the QoS ...

Abstract

The invention discloses a method for regulating the service quality parameters, which utilizes the PDP context modify process to reduce the QoS when the resource of mobile network is lacked, and increases the QoS parameter when the resource of node device is recovery. Said inventive method for automatically regulating the QoS according to the resource condition of mobile network can fully utilize present PDP context modify process while only requests the node device stores the unmodified QoS parameter and modified QoS parameter for deciding the following regulation of QoS, when its generates the PDP context modify process according to the self-condition of resource. Since the interface process and the information are avoided modified, the invention can be processed easily, while it can supply better network service quality, improve the satisfaction of users and increase the benefits of operators.

Description

technical field [0001] The present invention relates to the control technology of service quality (QoS) in the communication system, especially a method for adjusting service quality parameters. Background technique [0002] With the combination of mobile communication technology and Internet (Internet) technology, the use of mobile data services will become more and more extensive. How to provide users with reliable end-to-end service quality assurance is one of the most concerned issues for every operator. [0003] QoS control in the mobile network is mainly considered in three parts: user terminal, access network and core network. The SGSN is the edge node of the mobile network connecting the core network and the access network, and the GGSN, as the gateway of the mobile network, is the intercommunication node with the external IP network. In the mobile network, packet data bearer is implemented through a packet data protocol context (PDP context) connection. When a te...
