Embodiment Construction

[0028] Network service quality of service (QoS for short) is an agreement on the quality of information transmission and sharing between users on the network and between users communicating with each other on the network. In 3GPP, the services carried in the future communication system are divided into four categories according to their QoS requirements: conversational services, streaming services, interactive services, and background services. As shown in Table 1, the rates and delays required by various services are different.

Abstract

The disclosed wireless resource scheduling method for grouping business based on QoS comprises: determining business PRI for resource scheduling; to different type user, allocating resource for user with average data rate less GBR; calculating PRI for every user according to current rate, average rate and overtime threshold or based on buffer ratio, and allocating resource as user PRI. This invention allocates resource more flexibly, and can adapt resource management in future.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a wireless resource scheduling method for packet services. Background technique [0002] High Speed ​​Downlink Packet Access (HSDPA) is a technology to improve the downlink data transmission rate of Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) system. (Release 5) version of the system standard proposed, under the existing TD-SCDMA system network structure, the user downlink service data rate can be increased to above 2.8Mbps. [0003] FIG. 1 is a schematic diagram of a partial structure of a cell in a WCDMA or TD-SCDMA system. As shown in Fig. 1, the system includes a radio network controller (RNC), a base station and a user equipment (UE). The resources related to HSDPA in the cells of the TD-SCDMA system include High Speed ​​Physical Downlink Shared Channel (HS-PDSCH, High Speed-Physical Downlink Shared Channel), which is used to transmit se...
