Problems solved by technology

However, when the IP bearer contains a variety of different media components, and these different media components have different QoS requirements, this QoS control method based on the IP bearer cannot be implemented for different service data flows in the bearer. The problem of precise QoS control, thus, makes the utilization of network resources inefficient

example 1

[0146] Example 1. The flow rate negotiation process based on the GPRS QoS negotiation method is shown in Figure 8.

[0147] In Figure 8, in step 1, the UE sends an activation PDP context request message to the SGSN in the network according to the needs of its own application, and the request message contains the traffic identification information of each service data flow in the PDP context and its corresponding traffic Rate requirements, traffic identification information such as IP quintuple, transport layer protocol number, application layer protocol number, etc.; in addition, the request message can also contain other QoS control parameters, such as QoS type, which is traffic type, priority and and delays etc.

[0148] In step 2, after receiving the PDP context activation request message from the UE, the SGSN independently judges the traffic rate requirements in the PDP context activation request message according to its own capabilities, load conditions and subscription i...

example 2

[0155] Example 2. The flow rate negotiation process based on the SBLP QoS negotiation method is shown in FIG. 9 .

[0156] In Figure 9, in step 1, the session initiating terminal UE and the peer terminal or application server negotiate the session media parameters including the QoS requirements of each media component through the application layer signaling SIP / SDP, the AF learns the negotiation result, and the AF learns the negotiation The result is mainly the service information related to QoS, such as the bandwidth negotiation result of each media component. The AF can choose whether to send the business information to the PDF at this time, or to send the business information to the PDF later when the PDF requests the business information. If AF chooses to send business information to PDF at this time, PDF will authorize each media component after receiving the business information, and the authorization result will be saved on PDF in the form of IP QoS. IP QoS can include ...

example 3

[0168] Example 3. The flow rate negotiation process based on the PCC QoS negotiation method is shown in FIG. 10 .

[0169] In this embodiment, the bearer environment selects GPRS, therefore, the basic IP bearer unit is the PDP context. In addition, this embodiment does not include an AF functional entity, that is, the PCRF cannot obtain any information related to upper-layer services before traffic rate negotiation.

[0170] In Fig. 10, in step 1, the UE sends an activation PDP context request message to the SGSN in the network, and the request message includes the traffic identification information and the corresponding traffic rate requirements of each service data flow in the PDP context. In addition, The request message may also include other QoS control parameters, such as QoS type, that is, traffic type, priority, and delay.

[0171] In step 2, after receiving the activation PDP context request message transmitted by the terminal, the SGSN judges the traffic rate requir...

Abstract

The provided control method for QoS comprises: setting the relation for business data flow mark information and QoS control parameter in the node past by IP loading, letting the node provide QoS control for business data flow, and letting network have QoS control for business data above data flow level, so refining the QoS control precision for IP loading. This invention is flexible, can avoid system resource waste, and improves network control and resource utility capacity.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a QoS control method and system. Background technique [0002] In a mobile communication network, QoS (Quality of Service, Quality of Service) guarantee for services is a network characteristic that operators must implement, and is a prerequisite for developing services in the network. [0003] In UMTS (Universal Mobile Telecommunications System, Universal Mobile Communications System) network, different services can be divided into four types based on different QoS requirements. These four types of services are conversational (conversational) services, streaming (streaming) ) business, interactive business and background business. Among them, the conversational service and the streaming service belong to the real-time service, while the interactive service and the background service belong to the non-real-time service. Different types of services have different Q...
