Method for multi-business scheduling based on communication system real buffer memory

Abstract

The invention relates to a method for modulating multi-service, which is based on the actual cache amount of a communication system and comprises: firstly calculating the weight priority of each user who will be modulated only according to the actual cache amount without differentiating the weight priority of each user who will be modulated, distributing sub-channels of the communication system to each user who will be modulated according to the weight priority, then judging if all communication channels of the communication system are distributed to users who will be modulated with high professional work priority according to the professional work priority of each user which will be modulated or not, if all communication channels of the communication system are not distributed to users which will be modulated with high professional work priority, further judging if the users with high professional work priority are waiting for distributing communication channels or not, if all communication channels of the communication system are distributed to users which will be modulated with high professional work priority, redistributing the communication channels which are corresponded to the users which will be modulated and are distributed with the communication channels with low professional work priority and low weight priority to the users which will be modulated with high professional work priority and are waiting for distributing communication channels, thereby the diversity efficiency of the users can be intensified, the filling probability can be reduced, the increase of system throughput can be realized, and multi-service treating principles can be satisfied.

Description

technical field [0001] The invention relates to a method for multi-service scheduling based on the actual buffering capacity of a communication system. Background technique [0002] In recent years, Orthogonal Frequency Division Multiple Access (OFDMA: Orthogonal frequency division multiple access) technology has been adopted by the International Telecommunication Standardization Organization because of its advantages of making full use of various diversity effects and eliminating interference in the cell. The third generation partnership (3GPP) is defined as the downlink air interface technology of the future mobile communication system. [0003] Orthogonal Frequency Division Multiplexing (OFDM) access technology combines multiple subcarriers into one subchannel and distributes it to one user at a time. Multiple subchannels form a channel set, and multiple users select different subcarriers in the channel set according to channel conditions and service requirements. channe...

In this way, when some users with high service priority but small data volume coexist with some users with low service priority but large data volume, such as VOIP users and FTP users, the actual buffer size will not be considered. It appears that VOIP users occupy good channels first, but for VOIP users, it is extremely wasteful to occupy too good channels, because they do not have too much data to transmit, and FTP users with a large amount of data can only occupy poor channels , which will reduce the throughput of the system
