Problems solved by technology

[0093] In the prior art, the QoS negotiation mechanism given in the SBBC stage (stage) 2 baseline manuscript is not perfect, and it does not provide if the QoS authorized by the application layer cannot pass the local policy decision of the PCRF, or if it is determined after the PCRF decision. The authorized QoS cannot be accepted by the AGW, that is, when the authorized QoS after the PCRF ruling has exceeded the allowable range of resources that the AGW can provide, how to carry out subsequent processing to ensure that the service request initiated by the user can be executed

Embodiment Construction

[0182] The core idea of ​​the present invention is: the user sends a service request to the AF on the network side; the AF on the network side performs QoS authorization on the service requested by the user; QoS establishes bearer resources for the service; otherwise, the network side judges whether to accept the degraded QoS authorized by the application layer, and if so, establishes bearer resources for the service according to the degraded QoS; otherwise, the network side determines that the QoS negotiation fails.

[0183] The acceptance by the network side refers to: the local policy decision of the PCRF in the network side is passed, and the AGW determines that the bearer network resources can meet the requirements.

[0184] The system for implementing the QoS negotiation mechanism in the present invention includes: MS, RAN, AGW, PCRF unit, and AF unit, wherein, the MS exchanges application layer information with the AF unit through the RAN, AGW, and the PCRF unit receives...

Abstract

This invention discloses a system to realize QoS consultative mechanism, including: MS, RAN, AGW, PCRF module, AF module, and the system further includes: the space between PCRF module with AF between modules includes: the connectivity of PCRF unit to receive the information of quality degradation QoS form AF unit authorized by application layer. The space between AGW and PCRF unit includes: the connectivity of AGW to receive the information of quality degradation QoS form PCRF unit authorized by application layer. The invention also provides a method to realize QoS consultative mechanism.

Description

technical field [0001] The present invention relates to a bearer control technology in a mobile communication system, in particular to a system and method for implementing a quality of service (QoS) negotiation mechanism in a service-based bearer control technology (SBBC, Service Based Bearer Control). Background technique [0002] The basic process of SBBC technology is: when a user initiates a service request, the application layer function (AF, Application Function) unit receives the service request message from the user, and according to the standardized QoS parameter mapping rules, converts the service request message carried in the service request message to The service description is mapped to QoS parameters such as bandwidth, delay, and delay jitter, and is sent to the PCRF unit through the interface with the Policy and Charging Rules Function (PCRF, Policy and Charging Rules Function) unit, that is, the Tx interface Regarding the QoS requirements of the services aut...
