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 Delay_U 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 elem...

Abstract

The invention discloses a method for an HSUPA scheduler to obtain service QoS information, which is characterized in that: when RNC needs to transmit service-related QoS information to Node B, the HSUPA scheduling of Node B is notified through Delay_U information in the NBAP protocol The device acquires the delay-related QoS parameters of the service, wherein the Delay_U information is included in any channel information of the E-DCH logical channel information of the NBAP protocol and the E-DCH logical channel information to be modified. The invention also provides a method for improving the quality of wireless communication uplink service. By using the method of the invention, the HSUPA scheduler can obtain the QoS information about the service delay, thereby effectively guaranteeing the service quality requirement of a certain service on the SDU transmission delay.

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...
