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

The Enhancement Method of high-speed down data access

Technical field

The present invention relates to 3G (Third Generation) Moblie, particularly a kind of method that provides high-speed down data to insert.

Background technology

The high-speed down data access technology be introduce among the 3GPP provide the service bearer mode of down high-speed data for the user.A notable attribute is to have introduced h-arq HARQ in this method.HARQ mechanism refers to transmitting terminal Node B and sends data for user UE, if user side is correctly received these data, just sends out message to transmitting terminal and confirms, if user side can not correctly receive packet, just sends to transmitting terminal and denies message.If it is acknowledge message that transmitting terminal is received, so just stops to send this packet, otherwise just resend this packet.Whether the affirmation that the user sends to the base station recognizes message transmits by physical layer channel HS-DPCCH, because the data carried by data reliability is not very high on this channel, therefore proposed a kind of to its method that strengthens at 3GPP, that is exactly that subscriber equipment not only sends and confirms and deny, has also increased two other amount of information newly: front signal preamble and back signal postamble.These four signals send with different power and coded system, and Node B is by these four different signals of differentiation, thereby raising is to confirmation of receipt and the correct degree of denying.

Whether Node B uses this HARQ pattern, be that the .CRNC that CRNC controlled by control Node B network radio resources is the controlled entity with respect to Node B. and hereinafter employed SRNC and DRNC to be controlled entity .CRNC with respect to subscriber equipment be present in same physical entity with SRNC and DRNC, just function in logic is different. because Node B always can not support this mode, promptly Node B does not support to receive the signal of four patterns of HS-DPCCH.If Node B does not support this mode, the control radio network controller CRNC under the Node B just can not dispose this function at Node B so, otherwise the reliability decrease that causes Node B confirmation of receipt easily and deny.If but Node B does not support this function in the present standard, Radio Link will be rejected so, and inform that CRNC Node B does not support this function.After CRNC knows, resend message again and give Node B, this message does not require that Node B activates this message, thereby sets up new Radio Link.Referring to Fig. 1.This method can cause CRNC set up the message of Radio Link for twice will for Node B transmission, increases the weight of the system signaling load.And if when the lur interface is arranged, can bring heavier load to network.

Summary of the invention

The purpose of this invention is to provide a kind of by successfully setting up Radio Link and informing that the method for the ability of CRNC NodeB solves the problem that present system exists.

According to an aspect of of the present present invention, a kind of Enhancement Method of high-speed down data access comprises step:

Radio network controller CRNC sends a request message to the base station, activates the HARQ enhancement mode;

If the HARQ enhancement mode is supported in the base station, the base station just receives front signal preamble or back signal postamble on HS-DPCCH, and in the response message that returns, inform radio network controller CRNC/DRNC base station activation HARQ enhancement mode, wherein, described request message is that Radio Link is set up request, radio link reconfiguration is prepared or the radio link reconfiguration request, and described response message is that Radio Link is set up response, radio link reconfiguration finishes or the radio link reconfiguration response.

According to another aspect of the present invention, a kind of Enhancement Method of high-speed down data access comprises step:

The first radio network controller SRNC sends first request message and activates the HARQ enhancement mode to the second radio network controller DRNC;

The second radio network controller DRNC/CRNC sends second request message to the base station, activates the HARQ enhancement mode;

If the HARQ enhancement mode is supported in the base station, the base station just receives front signal preamble or back signal postamble on HS-DPCCH, and informs that in first response message that returns DRNC/CRNC supports the HARQ enhancement mode;

DRNC/CRNC informs that in second response message SRNC supports the HARQ enhancement mode, wherein, first and second request messages are that Radio Link is set up request, radio link reconfiguration is prepared or the radio link reconfiguration request, and described first and second response messages are that Radio Link is set up response, radio link reconfiguration finishes or the radio link reconfiguration response.

Can set up Radio Link quickly by the present invention, reduce the signaling of transmitting between network node.

Embodiment

Below with reference to accompanying drawing the present invention is described.As shown in Figure 2, the present invention utilizes existing lub and lur message: Radio Link is set up request and response message.Set up the enhancement mode (HARQ preamble pattern) that SRNC in the request message allows DRNC or CRNC (this CRNC can be present in an entity with SRNC, also can be present in a physical entity with DRNC) allow Node B set up Radio Link and activates HARQ at Radio Link.If Node B supports this method, so just set up Radio Link, and the pattern that receives HS-DPCCH is four kinds, set up at the Radio Link that returns and tell CRNC Node that B supports this method in the response message.If Node B does not support this method, Node B also sets up this Radio Link so, but the pattern that receives HS-DPCCH has only two kinds, and set up at the Radio Link that returns and to tell CRNC Node that B does not support this method in the response message, thereby the sending mode that makes SRNC to reconfigure to confirm on user's the HS-DPCCH or deny etc.

Said method also is adapted to when lub and lur interface carry out wireless link synchronization or asynchronous reconfiguring.

Fig. 3 provides is when carrying out the signaling process figure of synchronised radio link when reconfiguring.

When SRNC decision is carried out synchronous reconfiguring to Radio Link, send radio link reconfiguration to DRNC and prepare message, DRNC/CRNC sends radio link reconfiguration to Node B and prepares message, and the parameter of carrying in this message can be referring to 3GPP TS 25.423 and 25.433.Require Node B to activate the HARQ enhancement mode in this message, promptly Node B will receive four kinds of patterns of HS-DPCCH.If Node B supports this pattern, so just in finishing message, the radio link reconfiguration of returning tells DRNC/CRNC, tell SRNC Node the ability of B by DRNC then.If Node B does not support this pattern, so also in finishing message, the radio link reconfiguration of returning tells DRNC/CRNC, tell SRNC Node that B does not support this method by DRNC then.

Fig. 4 provides is when carrying out the signaling process figure of non-synchronous wireless links when reconfiguring.

When the SRNC decision is carried out asynchronous reconfiguring to Radio Link, send radio link reconfiguration request message to DRNC, DRNC/CRNC sends radio link reconfiguration request message to Node B, and the parameter of carrying in this message can be referring to 3GPP TS 25.423 and 25.433.Require Node B to activate the HARQ enhancement mode in this message, promptly Node B will receive four kinds of patterns of HS-DPCCH.If Node B supports this pattern, so just in the radio link reconfiguration response message that returns, tell DRNC/CRNC, tell SRNC Node the ability of B by DRNC then.If Node B does not support this pattern, so also in the radio link reconfiguration response message that returns, tell DRNC/CRNC, tell SRNC Node that B does not support this method by DRNC then.
