This method will cause CRNC to send two messages to Node B to establish a wireless link, which will increase the signaling load of the system.
And if there is an Iur interface, it will bring a heavier load to the network

Embodiment Construction

[0018] The present invention is described below with reference to the accompanying drawings. Such as figure 2 As shown, the present invention utilizes existing lub and lur messages: radio link setup request and response messages. In the radio link establishment request message, SRNC asks DRNC or CRNC (this CRNC can exist in one entity with SRNC, can also exist in one physical entity with DRNC) to ask Node B to establish a radio link and activate the enhanced mode of HARQ (HARQ preamble model). If Node B supports this method, then establish a wireless link, and receive HS-DPCCH in four modes, and tell CRNC Node B to support this method in the returned wireless link establishment response message. If Node B does not support this method, then Node B also establishes the wireless link, but there are only two modes for receiving HS-DPCCH, and tells CRNCNode B in the returned wireless link establishment response message that it does not support this method, thus It enables the S...

Abstract

A high-speed downward data cut-in mode enhancement method, the steps are: when CRMC activate HARQ enhancement mode by the Node B, the method set or reconfigure the wireless link successfully whether or not the Node B sustain the method; the repeat information from the Node B to RNC informs whether or not the Node B sustain the method. The invention can set the wireless link quickly, reduces the signal order that transmits between the network nodes.

Description

technical field [0001] The invention relates to the third generation mobile communication, in particular to a method for providing high-speed downlink data access. Background technique [0002] The high-speed downlink data access technology is introduced in 3GPP to provide users with downlink high-speed data service bearer. A notable feature of this method is the introduction of Hybrid Automatic Repeat Request (HARQ). The HARQ mechanism refers to that the Node B at the sending end sends data to the user UE. If the user end receives the data correctly, it sends a message to the sending end for confirmation. If the user end cannot receive the data packet correctly, it sends a deny message to the sending end. If the sending end receives a confirmation message, it stops sending the data packet, otherwise it resends the data packet. The acknowledgment and denial messages sent by the user to the base station are transmitted through the physical layer channel HS-DPCCH. Since the ...
