Problems solved by technology

[0008] Therefore, according to the definition of the current 3GPP standard, the HSUPA scheduler cannot obtain the QoS information about the service delay, which will cause the HSUPA scheduling to be unable to effectively guarantee the service quality requirements of a certain service for the SDU transmission delay

Embodiment Construction

[0029] In order to facilitate a deep understanding of the technical content of the present invention, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0030] The present invention adopts the E-DCH Logical Channel Information (E-DCH Logical Channel Information) and the E-DCH Logical Channel Information (E-DCH Logical Channel To Modify) in the Node B Application Part (NBAP: Node B Application Part) protocol Introduce a new DelayU information element (IE, Information Element) to notify the HSUPA scheduler on the Node B to obtain the delay-related QoS parameters of the service. Scheduling transmission authorization to meet the requirements of the service on the delay index, thus improving the guarantee of the scheduler for the service delay characteristics.

[0031] The definition of the Delay U information element to be added in the NBAP protocol is shown in Table 1, and the Delay U information eleme...

Abstract

A method for object service QoS information by HSUPA dispatcher includes using Delay U message in NBAP protocol to inform HSUPA dispatcher of Node B to obtain delay relevant QoS parameter of service when QoS information related to service is required to be sent to Node B by RNC and containing said Delay U information in either E-DCH logical channel information of NBAP protocol or in E-DCH logical channel information to be revised. The method for raising uplink service quality of radio communication is also disclosed.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for improving the quality of uplink services in a wireless communication system. Background technique [0002] The WCDMA (Wideband Code Division Multiple Access) system is a broadband cellular wireless communication system based on CDMA. The WCDMA system supports more types of services and higher data rate service transmission capabilities. HSUPA (High Speed ​​Uplink Packet Access) is a WCDMA system enhancement technology for uplink transmission capability. HSUPA technology includes shorter TTI (Transmission Time Interval), Node B-based scheduler and HARQ (Hybrid Automatic Retransmission reQuest), the new transmission channel E-DCH (Enhanced Dedicate Channel) adopts these key technologies, and the HSUPA system can perform better than traditional The WCDMA version of WCDMA has significantly improved the transmission performance of uplink services, about 50%-70% increase in syst...
