Problems solved by technology

[0014] However, in the existing enhanced uplink, when a mobile station UE communicating with data streams of multiple priority classes receives a common absolute speed control channel (E-AGCH), it needs to manage The transmission speed of each data stream has a problem that the configuration of the mobile station UE or the radio base station NodeB becomes complicated

Embodiment Construction

[0032] (Mobile communication system according to the first embodiment of the present invention)

[0033] The configuration of the mobile communication system according to the first embodiment of the present invention will be described with reference to FIGS. 1 to 8 . Among them, as shown in FIG. 10 , the mobile communication system according to this embodiment includes a plurality of radio base stations NodeB#1-#5 and a radio network controller RNC.

[0034] In addition, in the mobile communication system according to this embodiment, "HSDPA" is used for the downlink, and "EUL (Enhanced Uplink)" is used for the uplink. In addition, in both "HSDPA" and "EUL", HARQ-based retransmission control ((N process stop and wait (N process stop and wait)) is performed.

[0035] Therefore, in the uplink, the Enhanced Dedicated Physical Channel (E-DPCH) composed of the Enhanced Dedicated Physical Data Channel (E-DPDCH) and the Enhanced Dedicated Physical Control Channel (E-DPCCH), and the ...

Abstract

It is possible to simplify management of data flow transfer rate of a plurality of priority levels and suppress load on a mobile station and a radio base station. A transfer rate control method includes: a step that a radio base station (Node B) transmits a common absolute rate control channel containing the priority level and the transfer rate; and a step that when a mobile station has data flows of a plurality of priority levels, all the data flows are transmitted with the transfer rate contained in the common absolute rate control channel corresponding to the highest priority level.

Description

technical field [0001] The present invention relates to a transmission rate control method, a mobile station, and a radio base station for controlling a transmission rate in an uplink. Background technique [0002] In a conventional mobile communication system, the radio network controller RNC is configured to consider the radio resource of the radio base station NodeB, the amount of interference in the uplink, the mobile station The transmission power of the UE, the transmission processing performance of the mobile station UE, or the transmission speed required by the upper layer application determine the transmission speed of the dedicated channel. According to the message of the third layer (Radio Resource Control Layer), the mobile station UE and the wireless base station NodeB Each of them sends a notification of the determined transmission rate of the dedicated channel. [0003] Here, the radio network controller RNC exists in the upper layer of the radio base station...
