Abstract
Adding the optional QoS parameters of the relevant message of the radio network subsystem application part (RNSAP) and the node B application part (NBAP) makes the node B and the drift radio network controller (DRNC) know the QoS information in the application layer of the dedicated transmission channel frame protocol data unit (DCH FP PDU). Based on the QoS parameter, the QoS differentiation of the DCH FP PDU Iub/Iur interface transmission network layer is carried out. When low-speed link is adopted in the Iub/Iur, based on the QoS information in the DCH FP PDU application layer, the mapping between the Node B/RNC and the ML/MCPPP priority can carry out. The different categories of the transmission network layer QoS can be provided for DCH FP PDU with different types of operations so as to utilize the network resources more effectively.
Description
Technical field
The present invention relates to Wideband Code Division Multiple Access (WCDMA) (WCDMA) mobile communication system, the method that a kind of user's face transport network layer service quality (QoS) the when wireless access network system that relates in particular to the WCDMA system transmits based on IP is distinguished.
Background technology
Universal mobile telecommunications system (UMTS:Universal Mobile TelecommunicationSystems) is to adopt the 3-G (Generation Three mobile communication system) of WCDMA air interface.Usually also the UMTS system is called the WCDMA communication system.The logical network unit of UMTS system can be divided into UMTS grounding wireless access network (UTRAN:UMTS Terrestrial Radio Access Network) and core net (CN:Core Network) on function.Wherein UTRAN is used to handle all and wireless function associated, and all voice calls in the UMTS system are connected with data and the exchange and the route of external network and CN handles.Above-mentioned two network element have constituted whole UMTS system with subscriber terminal equipment (UE:User Equipment).
Referring to UTRAN network configuration shown in Figure 1, UTRAN comprises many RNSs (RNS) that are connected to CN by the Iu interface.A RNS comprises a radio network controller (RNC:Radio Network Control) and one or more wireless base station (Node B).Node B comprises one or more sub-districts, is connected to RNC by Iub interface.RNC is responsible for determining the switching of UE, has merging/separation function, in order to be supported in the grand diversity between the different N ode B.By Iur interactive interfacing information, the Iur interface can be the directly continuous of physics between the RNC or pass through suitable transmission network and realize between RNC.
In the process that RAB (RAB) is set up, core net CN issues by wireless access network applying portion (RANAP) in " RAB request for allocation " (RABAssignment Request) message of Serving RNC (SRNC) and comprises the RAB parameter, wherein indicate professional type (TrafficClass) and comprised session, stream, mutual, background, Maximum Bit Rate, guarantee bit rate, transfer delay or the like.RANAP is the wireless network layer of Iu interface.The concrete parameter of the RAB attribute of different kinds of business can be joined and is shown in Table 1.

The QoS of UMTS can be divided into four classes: session, stream, mutual, background.Real time business comprises session and stream, and typical conversation applications such as voice, typical stream are used as video etc.Non real-time is used and is comprised mutual and background, typical interactive application such as web browsing, typical background applications such as email etc.These the four types difference of using the QoS demand are very big.
SRNC has known the relative and absolute QoS demand of RABs, can carry out the mapping with transport network layer QoS.For Iu interface, the SRNC Iub interface to the Iur interface of Drift Radio Network Controller (DRNC) direction, SRNC to Node B direction, the simplest method can be distinguished according to the QoS that the type of service in the RAB qos parameter (Traffic Class) carry out transport network layer.
For the Iub/Iur interface user plane, when the transmission of the UTRAN of WCDMA system terrestrial interface is based on AAL2/ATM, perhaps do not provide the transport network layer QoS of Iub/Iur interface to distinguish, all business all adopt the urgent type of service of time delay, perhaps rely on SRNC to set up in request (ALCAP Establish Request) message at transmission network control protocol ALCAP and have path type parameter (PathType IE), the QoS that is used for carrying out transport network layer to DRNC/Node B distinguishes.
Because the plurality of advantages of IP and the impact of global ip tide, the WCDMA system introduces IP as optional transmission technology in UTRAN, is adopting the IP technology to come command transmitting and user data under the situation that does not change the UTRAN network configuration on the Iu/Iur/Iub interface.For DRNC and Node B, do not exist owing to resemble the such parameter of RAB QoS demand among present wireless application layer RNSAP, the NBAP, DRNC and NodeB do not know the QoS information of application layer.And the foundation of Iub/Iur interface user plane transmission bearer does not need transmission control protocol ALCAP when transmitting based on IP, therefore, the QoS information that does not have application layer among Node B, the DRNC can't be carried out Node B and be distinguished to the QoS of the Iur interface user plane transport network layer of SRNC direction to the Iub interface of controlling RNC (CRNC) direction, DRNC.
Because when prior art UTRAN transmits based on IP, the QoS information that does not have application layer among Node B, the DRNC, can't carry out Node B and distinguish to the QoS of the Iur interface user plane transport network layer of SRNC direction, tend to bring a lot of problems to the Iub interface of CRNC direction, DRNC.For example:
When if Iub/Iur interface physical layer adopted low speed chain circuit such as E1/T1 when 1, IP transmitted, the propagation delay time of circuit is bigger, packet as 1500 byte Byte needs 6.25 milliseconds (ms) by E1, in order to prevent that real-time voice parcel from not blocked by big packet, need to adopt the multi-class peer-peer protocol ML/MCPPP of branch chip technology multilink of data link layer, the ML/MCPPP priority class different to different traffic assignments.Have only Node B/DRNC to know that the QoS information of application layer just can carry out the mapping between ML/MCPPP priority class and the application layer QoS information.
Even 2 Iub/Iur adopt high-speed interface, to distinguish if do not carry out the QoS of transport network layer, all types business all adopts real-time QoS grade, the resource of waste IP network that also can be a large amount of.
