Embodiment Construction

[0036] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0037] figure 1 The mechanism of the downlink data packet scheduling method for the mobile communication system according to the embodiment of the present invention is described.

[0038]As shown in the figure, in the data packet scheduling mechanism, it is assumed that m users are stored in the real-time data buffer 10 and n users are stored in the non-real-time data buffer 20 at the same time.

[0039] The real-time video services of m users are input and stored in the real-time data buffer 10, so that the real-time video services are generated in parallel and corresponding to the number of users. In addition, non-real-time video services of n users are stored and accumulated in the non-real-time data buffer 20, thereby generating non-real-time video services in parallel and corresponding to the number of users.

[0040] The packet scheduler 30 serve...

Abstract

A system and method for downlink packet scheduling in a mobile communication system includes inputting real-time video traffic and non-realtime Internet traffic included in multimedia traffic into a packet scheduler positioned in a base station; providing service priority in input real-time video traffic, and performing packet scheduling of the real-time video traffic using a signal-to-interference ratio and an accumulation counter; discarding packets having a buffering window delay exceeding a predetermined reference value, the discarding of packets being performed during the packet scheduling of the real-time video traffic; and performing packet scheduling of the non-realtime Internet traffic using a signal-to-interference ratio in the case where there is no real-time video traffic to be serviced.

Description

[0001] priority [0002] This application is based on Patent Application No. 2002-80314 filed with the Korean Intellectual Property Office on December 16, 2002, the contents of which are incorporated herein by reference. technical field [0003] The invention relates to a system and method for scheduling downlink data packets in a mobile communication system, as well as a recording medium storing its program. More particularly, the present invention relates to a downlink data packet scheduling system and method in a mobile communication system in which priority is given to real-time video services and multimedia services are provided simultaneously. Background technique [0004] The performance of the downlink data packet scheduling algorithm in the mobile communication system affects the overall performance of the system. Therefore, the new downlink data packet scheduling must be able to support multimedia services with different QoS (Quality of Service). In addition, whe...
