Problems solved by technology

[0008] This scheduling method only relies on logical channel priority to determine the transmission order of service data packets. Since packet data does not require high real-time performance, it usually has a lower priority and cannot be prioritized for scheduling, which may cause packet data to be delayed. Congestion, so this scheduling method is not suitable for packet service transmission in a real-time environment; and the existing scheduling method only adjusts the transmission rate through the dynamic change of TFCS, and cannot effectively, high-speed, and real-time schedule data services

Embodiment Construction

[0043] The services supported by 3GPP (Third Generation Partnership Project) are divided into four categories according to QoS (Quality of Service), background services, such as SMS, multimedia messages, etc.; interactive services, such as WAP (Wireless Application Protocol), games, E- mail (e-mail), Internet browsing, etc.; streaming services, such as audio streaming and video streaming; conversational services, such as voice, video telephony, fax, etc. These services have different requirements for data transmission speed; even for the same business, the data transmission speed is different due to the different data volume, but there is a range of data transmission speed. Most of the grouping services belong to the interactive services and background services. Usually, the interactive packet service has higher delay requirements than the background packet service, so the priority of the interactive service is generally higher than that of the background service.

Abstract

This invention discloses one method for mobile communication system set business transfer, which comprises the following steps: setting each business time lag and when one user requires for multiple set business, wireless linkage control RLC layer determines each business data priority according to each set of business time lag; media interface control MAC layer selects the user business transmission form combination of TFC according to each logic signal channel priority and each business data priority.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method for dispatching packet services in a mobile communication system. Background technique [0002] In the mobile communication system, the function of packet scheduling is mainly implemented in RRM (Radio Resource Management) and the data link layer of the radio interface. The so-called packet scheduling refers to allocating corresponding wireless resources for packet services according to the occupancy of system resources, and balancing the transmission of service data according to the QoS (Quality of Service) requirements of the packet services. [0003] Packet scheduling controls the distribution of packet data, including monitoring system packet load and available capacity, selecting transmission channels, and assigning and modifying air interface rates. Packet scheduling allocates transmission channels according to data volume, delay requirements, uplink ...
