Problems solved by technology

But for the drift radio network controller (DRNC) and the base station (NodeB) in the system, it is impossible to know the QoS of each RAB, and because the radio network subsystem application part protocol (RNSAP) and DRNC used between the current DRNC There are no parameters such as RABQoS requirements in the Base Station Application Part Protocol (NBAP) used between the NodeB, so that the DRNC and NodeB in the system cannot know the QoS information of the application layer, and cannot carry out the transmission network of the Iub and Iur interfaces Layer QoS distinction
[0005] Therefore, in the process of IP-based data transmission in UTRAN, because there is no QoS information of

Embodiment Construction

[0021] During the establishment of the wireless link, the RAB parameters delivered by the CN to the SRNC include QoS parameters corresponding to specific service types, and corresponding service data can be transmitted according to the QoS parameters. Since the established link channel is used to bear the transmission of downlink and uplink service data, in practice, the QoS of uplink service data can be determined completely according to the QoS included in the RAB parameters. DiffServ provides a variety of externally visible forwarding processing characteristics (PHB) type values, including: EF (Expedited Forwarding), AF (Assured Forwarding), BE (Best Effort), NC (Network Control), etc. Among them, EF is suitable for applications that support low loss rate and low delay to ensure bandwidth, and the corresponding DSCP value is 101110. AF can ensure that the IP packet loss probability of the application is very low when the service flow sent by the application to the network d...

Abstract

The invention discloses a transmission method of service priority in wireless access network, the method sets the correspondence relation between IE value of DCH or DSCH and the type value of DiffSer PHB; thus, when the wireless link is created or reconfigured, the SRNC receives the RAB parameter assigned by CN, it determines the value of frame process priority of DCH or DSCH according to the service type and the priority; SRNC uses wireless link to create or reconfigure message, and transmits the value to DRNC and NodeB, acquires the PHB value of upwards service by DRNC and NodeB according to the correspondence relation, and marks the DSCP value of upwards service. The project can make DRNC and NodeB acquire the QoS information of application layer, it solves the QoS specification problem of the Iub interface transmission network layer data based on IP data transmission process.

Description

technical field [0001] The invention relates to a data transmission method in a third-generation mobile communication system (3G), in particular to a data transmission method in a wireless access network of a wideband code division multiple access (WCDMA) system. Background technique [0002] In the 3G system, according to the regulations of the third generation partnership project 3GPP R5 version, the transmission technology based on the network (IP) layer is an optional data transmission technology, but due to the advantages of IP transmission, such as the current Internet, most Most terminal applications are based on IP, which can support multiple business mixes and low-speed links, automatic configuration, dynamic routing, etc., making it more and more widely used. In IP transmission, quality of service (QoS) is the most basic requirement. For example, in Universal Mobile Telecommunications System (UMTS), there are four main types of services: session, flow, interaction,...
