Method of mapping scheduler priority level mark in high speed down packet access system

Abstract

The method comprises: RNC pre-configures a mapping relation table between RAB parameters appointed by core network and the sign of scheduling priority; the RAB parameters comprise service class, allocation / reservation priority and service processing priority; said mapping relation table comprises a classification table of allocation / reservation priority, a classification table of service processing priority and a mapping relation sub-table of scheduling priority sign of all kind services; after the reception and control layer allows the RAB service access to high speed downlink packet access system, the RNC read out the RAB parameters in RAB appointing request, and based on the parameters, gets the scheduling priority sign corresponding to the service from the mapping relation table.

Description

Technical field [0001] The present invention relates to the field of communications, and in particular to a method for determining packet scheduling priority in a high-speed downlink packet access system (High Speed ​​Downlink Packet Access, hereinafter referred to as HSDPA). Background technique [0002] HSDPA is a new technology proposed by 3GPP (Third Generation Mobile Communication Partnership Project) in the R5 protocol in order to meet the asymmetric demand of uplink / downlink data services. It can well solve the contradiction between system coverage and capacity. Greatly increase the system capacity to meet the high-speed business needs of users. HSDPA introduces a short transmission time interval (2ms), adaptive modulation and coding (Adaptive Modulation and Coding, hereinafter referred to as AMC), multi-code transmission and hybrid automatic repeat request (Hybrid Automatic Repeat Request, hereinafter referred to as HARQ), and group The scheduler is transferred from a rad...

[0007] Chinese patent specification "Supporting method of high-speed downlink data packet access system for different service quality services" (patent application number: 01130571.1; authorization announcement number: CN1173500C; authorization announcement date: October 27, 2004) discloses a system The mapping and configuration method of quality of service parameters, but this method only mentions that the relative priority of the HS-DSCH data frame needs to be considered during packet scheduling, but does not provide a method for mapping the priority

[0008] However, in other published materials, when considering WCDMA packet scheduling priority mapping, either only the combination of service class priority and allocation / reservation priority is considered, or only the service class priority and interactive service processing priority are considered. level, and only consider the priority mapping between public channels and shared channels, which cannot truly and fully reflect the actual situation, so that the quality of service of users or services cannot be guaranteed, resulting in the interests of operators and users affected and damaged
