Description
Technical field
The present invention relates to moving communicating field, particularly relate to a kind of method of notifying Node B not have high-speed synchronous control channel operation change in the 3-G (Generation Three mobile communication system).
Background technology
In WCDMA (Wideband Code Division Multiple Access (WCDMA)) and TD-SCDMA (TD SDMA) system based on HSUPA/HSDPA (access of high speed uplink packet access/high speed downlink packet) technology, introduced CPC (Continuous Packet Connectivity, continuity transmitted in packets) technology.Proposed multiple technologies among the CPC, operated comprising HS-SCCH-less (no high-speed synchronous control channel).The HS-SCCH-less operation is specially at VoIP (Voice over IP, the IP speech) the professional design of class, adopted that transfer resource is prewired (promptly first, the transmission first of a grouping does not need to send the HS-SCCH channel), retransmit resource (promptly by the technical scheme of the scheduler schedules of NodeB (Node B), during re-transmission, need to send HS-SCCH).Because 90% transmitted in packets once just can success, thereby first the biography do not sent out HS-SCCH and will be reduced demand to the HS-SCCH control channel.As long as the reliability of transmission is kept certain level first, retransmission probability is not high, and then the control channel expense is very little.This technology sharpest edges are exactly to be that the VoIP business has been introduced AMC/HARQ (adaptive coding and modulating/automatic-answering back device retransmit) technology with very little cost, are proved to be simultaneously to have very high efficiency of transmission.
Retransmit HS-SCCH channel and the original HS-SCCH Channel Sharing physical resource that uses in the HS-SCCH-less operation, but strengthen on the basis of original frame structure, the frame structure after the enhancing is called HS-SCCH Type 2 (type 2).In new frame structure,, control informations such as transmission block size, HARQ merging indication, re-transmission RV Version Control have been designed at the VoIP business features.
When business was set up, RNC (radio network controller) can be provided with the parameter of HS-SCCH-less for UE, and disposed and give NodeB, and UE and NodeB judge whether to have activated the HS-SCCH-less function according to this parameter.Under the situation that HS-SCCH less has activated, for UE, as long as do not carry HS-SCCH less Information information in the UU mouth special RRC message, UE promptly can cancel HS-SCCH less operation.Yet under present protocol frame, RNC can't be NodeB cancellation HS-SCCH less operation or the parameter of revising HS-SCCH less operation by the standard procedure of IUB mouth.The flexibility that this has obviously limited system has greatly also damaged the integrality of protocol function.The HS-SCCH-less parameter of CPC is as shown in table 1 among Iub interface (interface between RNC and the Node B) NBAP (Node B application protocol) at present.

Embodiment
Below in conjunction with drawings and Examples technical scheme of the present invention is described in detail.
The invention provides a kind of method of notifying Node B not have high-speed synchronous control channel operation change, comprising:
For the arbitrary Radio Link that activates HS-SCCH less operation, if when RNC need change the HS-SCCH less operation of this Radio Link, RNC is by the HS-SCCH less operation change of this Radio Link of configuration signal notice NodeB;
Described change HS-SCCH less operation comprise following situation or wherein any:
Deactivating HS-SCCH less operation, modification HS-SCCH less operating parameter.
Wherein, when change HS-SCCH less operation was meant modification HS-SCCH less operating parameter, RNC was meant by the HS-SCCH less operation change of this Radio Link of configuration signal notice NodeB: RNC reshuffles HS-SCCH less operating parameter by sending configuration signal to NodeB.
Wherein, this method also comprises: after RNC reshuffled HS-SCCH less operating parameter by configuration signal, NodeB carried out the HS-SCCHless operation according to the parameter after reshuffling when reshuffling the activationary time arrival.
Wherein, described configuration signal comprise in the following signaling any or appoint several: Radio LinkSetup Request (Radio Link is set up request), Radio Link Addition Request (Radio Link increases request), Radio Link Reconfiguration Prepare (radio link reconfiguration preparation), Radio Link Reconfiguration Reuqest (radio link reconfiguration request) etc.
Further, this method also comprises: when RNC need activate the HS-SCCH less operation of a Radio Link, equally may further comprise the steps with prior art: RNC notified NodeB with the parameter of HS-SCCH less operation by configuration signal; NodeB receives configuration signal, if wherein there is the parameter of described HS-SCCH less operation, determines that then this Radio Link has activated HS-SCCH less operation.
Further, this method is applicable to the mobile communication system based on the HSUPA/HSDPA technology.
Wherein, RNC is meant by configuration signal notice NodeB HS-SCCH less operation change:
In " the CPC Information " of NBAP agreement (CPC information) cell, increase " Continuous Packet ConnectiVity HS-SCCH less Information To Modify " (modification of continuity transmitted in packets HS-SCCH less information) cell, this cell comprises one " CHOICEHS-SCCH less Information To Modify " (HS-SCCH less information is revised option) cell, should comprise two options by " CHOICE HS-SCCH less Information To Modfy " cell, one is " Modify " (modification), and another is " Deactivate " (it is invalid to make);
RNC carries in sending to the configuration signal of NodeB described " Continuous PacketConnectivity HS-SCCH less Information To Modiffy " cell; When RNC wants deactivating HS-SCCH less operation, described " CHOICE HS-SCCH less Information ToModify " is changed to " Deactivate "; When RNC will revise the parameter of HS-SCCH less operation, described " CHOICE HS-SCCH less Information To Modify " is changed to " Modify ".

According to the method described above, when needs during, only need the CHOICE HS-SCCH less Information To Modify in the Continuous Packet Connectivity HS-SCCH less Information To Modify cell is changed to Deactivate for NodeB deactivating HS-SCCH less; In addition, when needs are reshuffled HS-SCCH less for NodeB, only need the CHOICEHS-SCCH less Information To Modify in the Continuous PacketConnectivity HS-SCCH less Information To Modify cell is changed to Modify, and TransportBlock Size Index and/or the HS-PDSCH Second Code Support information upgraded are set get final product, can these two parameters not be provided with yet.
In this example, RNC notice Node B do not have high-speed synchronous control channel operation change method whole flow process as shown in Figure 1, comprising:
Step 1: RNC is NodeB configurating downlink HS-DSCH parameter and HS-PDSCH Radio Link, when this Radio Link need carry out HS-SCCH less operation, RNC sets up in the message at Radio Link, gives NodeB with the parameter configuration that HS-SCCH less operation relates to;
Step 2: during the HS-SCCH less content of parameter of this Radio Link of RNC desired modifications, prepare in the message in radio link reconfiguration, carry " Continuous Packet Connectivity HS-SCCHless Information To Modify " cell, and the content of cell is Modify, notify the HS-SCCH less content of parameter of this Radio Link of NodeB that modification is arranged, NodeB activates HS-SCCH less operation again when reshuffling activationary time arrival---carry out the HS-SCCHless operation according to the parameter after reshuffling;
When step 3: RNC wishes to cancel the HS-SCCH less operation of this Radio Link, prepare in the message in radio link reconfiguration, carry " Continuous Packet Connectivity HS-SCCH lessInformation To Modify " cell, and the content of cell is Deacitvate, notifies this Radio Link deactivating HS-SCCH of NodeB less operation.
During practical application, will deexcitation if after activation, do not revise, then there is not above-mentioned steps two; Iff being to activate, then there are not above-mentioned steps two and three; If only revise not deexcitation, then there is not above-mentioned steps three.
Certainly; the present invention also can have other various embodiments; under the situation that does not deviate from spirit of the present invention and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection range of claim of the present invention.
