Embodiment Construction

[0044] The core idea of ​​the present invention is: the HSDPA system generally includes background class, interactive class and streaming media, and the transmission delay, service priority and user's service quality requirements of different services are all different. All the services required above are necessary and an important factor reflecting the overall service quality of the HSDPA system. Aiming at the transmission delay requirements of mixed services in the HSDPA system and the user's service quality requirements, the present invention proposes a service priority determination method and a scheduling method, which fully considers the transmission delay requirements and service quality requirements, and combines the system's The transmission capacity and the proportional fairness of the transmission, the priority determined by the present invention are more three-dimensional and can better meet the service requirements of users, thereby improving the service quality of...

Abstract

The invention discloses a method for determining the business priority for a high-speed downlink package access (HSDPA) system, and relates to a mixed business scheduling technology in the HSDPA system. The technical proposal adopted is put forward to improve the service quality under the condition of mixed services of three types, which is to determine the scheduling priority at least according to the priority indicator parameter of the scheduling service and the priority parameter determined by the Proportional Fair Scheduling (PFS). The invention simultaneously discloses a device of achieving the method, which is to schedule the services according to the priority determination method. The invention further discloses a scheduling device based on the scheduling method. The invention enhances the service quality of HSDPA system.

Description

technical field [0001] The present invention relates to a scheduling technology for mixed services in a wireless communication system, more specifically, a method and device for determining the priority of mixed services in a High Speed ​​Downlink Packet Access (HSDPA) system, and a method and device for scheduling services. Background technique [0002] Future wireless cellular networks will support integrated multimedia applications with different QoS (Quality of Service) requirements. Providing QoS differentiation is considered to be a good solution to the increasing multimedia demands of wireless end users. In the HSDPA system, a high-speed downlink shared channel is shared by multiple users in the same cell. There are differences in service characteristics between multiple users, and a single user may simultaneously transmit several service data with different QoS requirements. For example, a user can browse video streaming media while downloading via FTP (File Transfe...
