A method and device for realizing the dynamic QoS control during the dispatching of HSUPA base station

Abstract

The related method for dynamic scheduling QoS in HSUPA BS comprises: using reported state message from user, message measured by BS and the configuration message in BS controller, applying delay control and / or speed control, and realizes the fast scheduling for dynamic grouping business. This invention can treat all QoS control problems in RNC and UE, reduces dependence on RNC, and improves wireless resource utility.

Description

technical field [0001] The present invention relates to UMTS (Universal Mobile Telecommunications System, Universal Mobile Communication System), in particular to a method and device for realizing dynamic QoS control in base station scheduling of UTRAN (UMTS Terrestrial Radio Access Network, UMTS terrestrial radio access network). Background technique [0002] UTRAN is composed of user equipment (UE), base station (Node B) and RNC (Radio network controller, radio network controller). The protocol structure of the radio interface (UE-UTRAN) is divided into physical layer and data link layer; RNC is responsible for Management of various interfaces, responsible for radio resource management (RRM); Node B is controlled by the RNC, completes the code conversion between the RNC and the wireless channel, and realizes related processing between the wireless interface and the physical layer, such as wireless channel coding, interleaving, and rate Matching and spread spectrum, etc., i...

Problems solved by technology

[0013] However, for method one, only the priority of logical channels is considered in UE-based ETFC selection

Although this method distinguishes the relative priority, it does not fundamentally guarantee the QoS information of the service such as delay

[0014] For method two, in the RRM related to E-DCH (Enhanced dedicated channel, enhanced dedicated transport channel) in the RNC, the control of QoS is adjusted by setting the HARQ attribute of each MAC-d flow, but the method for controlling QoS is only very simple. It controls the retransmission characteristics of HARQ well, and indirectly introduces QoS control in the scheduler, which can well control the packet loss rate and the average number of retransmissions, but it cannot control the service QoS such as waiting delay and minimum bit rate well. In addition, the RNC-based control method has a relatively large delay

In addition, if the service is mapped to the NST, the cell resources will be wasted, because the base station scheduling is not responsible for the scheduling of the business on the NST

[0015] Therefore, the QoS control in the current HSUPA is distributed in RNC and UE, and the base station scheduler only supports the parameters configured in the RNC for scheduling. It should be said that there is no perfect solution for processing service QoS in the scheduler controlled by the current base station
