Problems solved by technology

[0007] At present, in the 3G standard formulated by 3GPP, there is no detailed description and specific implementation method for the priority scheduling configuration and priority scheduling strategy of the forward access channel FACH in the common channel CCH, that is, the forward access channel The 3G standard does not give a description of the corresponding technical solution for the implementation process of the priority scheduling of the incoming channel FACH, which makes it difficult to implement in the field of FACH priority scheduling

Embodiment 1

[0100] Embodiment 1, assuming that there are two types of service data streams on the same DTCH, and their CmCH-PIs are 5 and 4 respectively, if the total transmission bandwidth that MACC can allocate to these two service data streams at a certain moment supports the transmission of 8 TB , and the two service data streams have 6 and 7 TB to be sent respectively, the transmission bandwidth allocated to the two service data streams supports the transmission of 6 and 2 TB respectively.

Embodiment 2

[0101] Embodiment 2, assuming that there are two types of service data streams on the same DTCH, and their CmCH-PIs are 5 and 4 respectively. The following table lists the number of TBs to be sent at 6 times and the actual transmission of TBs after priority scheduling quantity. Since the service data flow with a CmCH-PI of 5 has a higher priority, in the first four moments, the transmission bandwidth is preferentially allocated to it. However, in order to prevent the service data flow with CmCH-PI of 1 from being transmitted for a long time, at time 4 priority scheduling, the CmCH-PI of the service data flow with CmCH-PI of 4 is temporarily increased so that the actual CmCH-PI is 5, and at the time of priority scheduling at time 5, the CmCH-PI of the service data flow whose CmCH-PI is 4 is further increased, so that the actual CmCH-PI is 6, and then MACC will give priority to the original CmCH-PI of 4 Allocate the transmission bandwidth to the business data flow, so that it c...

Abstract

The invention discloses a channel priority scheduling realization method for executing priority scheduling processing to service data stream transmitted on same dedicated service channel DTCH. The method comprises A: separately configuring different common channel priority indication for different service data stream transmitted on same dedicated service channel; B: according to sequence from high to low of public channel priority indication for different data stream, priorly scheduling public channel high priority indication service data stream for transmitting at every moment; C: if service data stream of low common channel priority indication being not scheduled in a preset reference time period, then upgrading the service data stream common channel priority indication, then return to B. The invention enables scheduling process practical for service data stream of different priority sequence transmitted on same DTCH.

Description

[0001] This application is a divisional application for the invention patent application with the filing date of May 26, 2005 and the application number of 200510071896.3, which is named Channel Priority Scheduling and Service Priority Scheduling Realization Method. technical field [0002] The invention relates to the technical field of third-generation mobile communication, in particular to a method for realizing channel priority scheduling and service priority scheduling. Background technique [0003] In the 3G standard formulated by 3GPP, the universal terrestrial radio access network (UTRAN, Universal Terrestrial Radio Access Network) transmission channel is a channel provided by layer 2 (L2) to layer 1 (L1), which is used for layer 1 (physical layer) to transfer data between layers. According to different data transmission methods, the transmission channel can be divided into two parts: common channel (CCH, Common Channel) and dedicated channel (DCH, Dedicate Channel);...
