Service quality negotiation method, system and device

Abstract

The invention discloses a negotiation method, a system and a device of quality of service (QOS). The method of the invention comprises the steps that: a network-side receives a request sent by a request end for negotiating the configuration of service quality and judges whether the request for negotiating the service-quality configuration is accepted; if a plurality of service quality configurations requested for negotiation are partly accepted and partly refused, the parameters of the accepted service quality configuration and the corresponding refusal reasons of service quality configurations which are refused in part or in whole can be carried by the response information to be sent back to the request end; according to the response message, the request end correspondingly processes the service quality configurations which are refused and given refusal reasons on the basis of refusal reasons; and the request end processes the service quality configurations which are refused but not given refusal reasons on the basis of system conventions. The negotiation method, the system and the device of quality of service of the invention can partly accept and partly refuse a plurality of service quality configurations sent by the request end, ensuring that request end can process the refused service quality configuration accordingly, thereby, saving the network resource cost.

Description

technical field [0001] The present invention relates to the communication field, and in particular relates to a service quality negotiation method, a service quality management system, a policy decision-making functional entity and a radio network controller. Background technique [0002] With the enrichment of wireless business types, it is the development trend of wireless communication from circuit switching to packet switching. Packet switching technology can support the application of multimedia services. Generally speaking, users have different service quality requirements for different multimedia applications, which requires the network to allocate and schedule resources according to user requirements. [0003] QoS (quality of service, QoS for short) is a service quality guarantee mechanism of the network, and is a technology used to solve problems such as network delay and congestion. The network needs to have the ability to provide QoS management for different pack...

Problems solved by technology

[0017] If the AT requests too many reserved resources at one time, it is easy for the request to be unable to be fully satisfied. When the requested reserved resources cannot be satisfied, AN will reject all the requests, and AT will continue to open the resource reservation request. The sending of messages takes up network resources and increases network overhead.

[0018] In addition, the resource request opening message combines the configuration and the opening request, and the AN may reject the request because the requested QoS parameter configuration is inappropriate, or the parameters are reasonable but the network resources are insufficient.

For the former case, it is necessary to conduct new negotiation on the configuration attributes to form new network configuration parameters; for the latter case, re-negotiation of the configuration parameters will occupy network resources and increase network overhead
