Description
Technical field
The present invention relates to field of wireless communication, be reoriented to the method for dedicated channel service in the particularly a kind of TD-SCDMA system from high speed downlink grouping access business.
Background technology
Introduced HSDPA (high speed downlink packet access) technology in the Release5 version of TD-SCDMA (Time Division-Synchronous Code Division Multiple Access, TD SDMA inserts) system.In order to keep compatibility to the front version, be convenient to the exploitation of equipment, the change of TD-SCDMA standard in the Release5 version is also little, mainly is to add a new Media Access Control (MAC-hs) at Node B (Node B) to be used to control high speed data transfer.HSDPA (high speed downlink packet access) technology can improve the transmission rate of data significantly, thereby can greatly satisfy the demand of users to multimedia, two-forty mobile communication business.For the HSDPA business, the peak rate of single carrier frequency of TD-SCDMA can reach 2.8Mbps.
In the moving of UE, when the Serving cell signal quality decays to certain limit, system need switch to UE on the network quality better cell, when Serving cell and Target cell do not belong to same RNC (radio network controller), need switch by the mode of CN (core net) use reorientation.When carrying out reorientation, (between source RNC and the Target RNC) needs to transmit some rrc messages by RRC (Radio Resource control) information container (RRC in-formation container) between the network node of UTRAN.At first source RNC passes to Target RNC current UE all relevant informations on the interface aloft by the cell Source RNC toTarget RNC Transparent Container in the Relocation Required message; comprise encryption and integrity protection information, UE information element, UTRAN mobility information element, CN information element, metrical information element, RB information element and transmitting channel information element etc.Target RNC is according to the reference of these information as distributing radio resource.Target RNC is according to the reorientation resource allocation request from CN then, the current occupation condition in combining target sub-district, be the UE distributing radio resource, if the resource allocation success can return to source RNC to ready switching message by Target RNC to Source RNC TransparentContainer cell in the reorientation resource allocation success response message then.CN sends the reorientation command messages to source RNC then, after source RNC receives the reorientation order, by the resource allocation conditions of the new sub-district of RB reallocation message notice UE.
In actual applications, the version of RNC in the whole network (radio network controller) possibility disunity is when causing once finishing switching because of compatibility issue when support highest version network system switches to the lowest version network system.For example when the sub-district in the network that to switch to a RNC be the Release4 version of the sub-district the network that a UE with HSDPA business is the Release5 version from SRNC (source RNC), because DRNC (Target RNC) version can not be upward-compatible, can not decode the Source RNC to Target RNC Transparent Container cell of Release5 version, caused can not be disposable by reorientation mode by the rrc message container the rrc message among the SRNC be delivered to DRNC.SRNC must be before the trigger re-positioning process earlier the mode of the UE that carries out the HSDPA business by RB (radio bearer) reprovision from HS-DSCH (high speed descending sharing channel) channel switch to DCH (dedicated channel) channel, and then the trigger re-positioning process is carried out the sub-district switching.
Along with the network equipment of supporting the HSDPA technology is progressively upgraded, will occur switching to the lowest version network and incompatible situation from the highest version network, for example the UE of HSDPA business switches to the situation of ordinary groups business in the Release4 network from Release5 version network, if by the mode of RB reprovision UE is carried out repositioning process again from the HS-DSCH channel migration to the DCH state earlier for this situation is each, will waste the resource of network, also strengthen time delay for switching (at every turn all will carry out the channel conversion of HS-DSCH earlier) simultaneously to DCH; If this situation is not carried out the operation of HS-DSCH channel to the DCH channel migration earlier, then can't fill in HS-DSCH channel information in the rrc message container again.
Therefore, need in a kind of TD-SCDMA system, disposable in repositioning process UE (subscriber equipment) is switched to the technical scheme of Release4 version d CH business from HSDPA (high speed downlink packet access) business of Release5 version.
Summary of the invention

Embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments.
Main design of the present invention is: SRNC is DCH ID of HSDPA traffic assignments temporarily and brings DRNC, radio bearer reallocation message and the local information of taking back according to DRNC compared then, and the mode of finally determining to fill in the radio bearer reallocation message that sends to UE is finished directly the DCH business that is reoriented to the network of Release4 version from the HSDPA business of the network of Release5 version.
As shown in Figure 1, the method that directly is reoriented to the DCH business from the HSDPA business of the present invention is applied to the TD-SCDMA system, specifically comprises as follows:
Step 110, UE is after the HSDPA business is set up in source high speed descending sharing channel (HS-DSCH) sub-district, and this moment, UE was in the CELL_DCH state, and SRNC sends to UE and measures control messages;
Measure in the control messages and indicate the information that UE need measure, comprise information of adjacent cells etc.
Step 120, the SRNC return measurement report of UE under HS-DSCH sub-district, source;
Measurement report comprises adjacent measurement result with frequency or alien-frequency district.
Step 130, SRNC determines the target DCH sub-district that UE switches to according to the result of measurement report, and SRNC (source RNC) brings DRNC (Target RNC) with the resource allocation of current UE by Source RNC to Target RNC Transparent Container cell (need fill in the message cell of Release4 version) by Relocation Required (reorientation preparation) message;
SRNC prepares message and brings DRNC with the resource allocation of current UE by Source RNC to Target RNC Transparent Container cell by send reorientation to CN, and extends this as the resource allocation information of UE and be the professional interim parameters such as DCH information of distributing of HSDPA in the rrc message container of message is prepared in reorientation.
CN sends to DRNC reorientation resource allocation message after receiving that message is prepared in the reorientation of SRNC, is the SRNC side resource allocation information that brings DRNC in the rrc message container of reorientation resource allocation message.
Target DCH sub-district belongs to the sub-district of the RNC that only supports the Release4 structure.
Reorientation prepares to force in the message the professional downlink information of UE is mapped on the target DCH, is not with any HS-DSCH information.
The structure that Source RNC to Target RNC TransparentContainer cell need be filled in Release4 in the message is prepared in the reorientation that SRNC fills in, and can not fill in any cell relevant with HSDPA.
It is DCHN1 that SRNC need distribute a DCH ID separately for the HSDPA of UE is professional, and the descending transmission channel informational needs in the Source RNC to Target RNC Transparent Container cell is filled in the information that SRNC is the professional transmission channel DCH that distributes separately of HSDPA.
In the Source RNC to Target RNC Transparent Container cell in the RB mapping relations of the HSDPA business of UE descending logic channel need be mapped on the DCH N1.
Step 140, after DRNC receives Relocation Request (reorientation resource allocation) message of CN, and be the UE Resources allocation according to the rrc message container, set up Radio Link in target DCH sub-district, fill in Target RNC to Source RNC Transparent Container cell then, finish (Relocation Request Acknowledge) message by the reorientation resource allocation and bring SRNC;
After DRNC received the reorientation resource allocation message of CN, after DRNC was the success of UE Resources allocation, DRNC returned the reorientation resource allocation to CN and finishes (Relocation Request Acknowledge) message.
DRNC can redistribute transmission channel ID and transmitting channel information, the also transmitting channel information that can still use SRNC to bring, and DRNC must fill in RB reallocation message structure in the rrc message container.
Step 150, SRNC receives Relocation Command (reorientation) message of CN, the RB reallocation message of Release4 version is converted to the RB reallocation message of Release5 version among the Target RNC to Source RNC Transparent Container that DRNC is brought, and add the information of deleted HS-DSCH resource, send to UE then;
CN issues SRNC reorientation message after receiving that message is finished in the reorientation resource allocation of DRNC, brings the RB reallocation message parameter of SRNC in the rrc message container of reorientation message for DRNC.
SRNC sends RB reprovision (Radio Bearer Reconfig) message to UE, and fills in RB relevant parameter information in message.
SRNC need be with DRNC the RB reallocation message of the Release4 structure of filling in the rrc message container of coming to extend this as the RB reallocation message of Release5 structure.
SRNC need contrast the RB reallocation message in the rrc message container that local wireless resource information of preserving and DRNC band come, if have SRNC in the transmission channel of descending deletion because HSDPA business and the DCH N1 of particular allocation, SRNC can not fill in this DCH ID in the transmission channel of filling out to the descending deletion of the RB reallocation message of the Release5 of UE so; If in the RB reallocation message that DRNC brings, all there is not DCH N1 in the transmitting channel information of the transmitting channel information of descending deletion and descending increase reprovision, need to add DCH ID in the transmitting channel information of filling out to the descending increase reprovision of the RB reallocation message of the Release5 of UE be the transmission channel of DCH N1 to SRNC so, and the information of transmission channel this transmitting channel information of correspondence when bringing DRNC is the same.
SRNC need need to be added to the Mac-dFlow ID (the sub-traffic identifier of Mac-d) of HSDPA traffic assignments in the transmission channel of descending deletion in the RB reallocation message.
Step 160, DRNC is converted into source RNC from Target RNC after receiving that the RB reprovision of UE is finished message, sends Relocation Detect (reorientation detection) message and RelocationComplete (reorientation is finished) message then to CN (core net);
After UE receives the RB reallocation message,, after Target cell success synchronously, send the RB reprovision and finish the DRNC of (Radio Bearer Reconfig Complete) message to Target cell according to parameter configuration in the RB reallocation message.
Step 170, after SRNC received the IU release message of CN, the Radio Link in the deletion HS-DSCH sub-district, source was finished the DCH business that is reoriented to the Release4 version from the HSDPA business of Release5 version.
CN sends the IU release message to SRNC, and the Radio Link in the SRNC deletion HS-DSCH sub-district, source is finished the DCH business that is reoriented to the Release4 version from the HSDPA business of Release5 version.
SRNC fills in the flow process fragment that message is prepared in reorientation, and is specific as follows:
UE is after the HSDPA business is inserted in HS-DSCH sub-district, source, and when the SRNC judgement need be carried out reorientation, and the DRNC under the Target cell is the Release4 version, and SRNC need fill in the rrc message container of Release4 structure and give DRNC.
Wherein, SRNC at first is DCH ID of HSDPA traffic assignments of UE, generates corresponding DCH information then, and preserves, and sends reorientation and prepares message to CN.
Wherein, in the professional corresponding RB map information of HSDPA in the Source RNC to Target RNC Transparent Container cell of rrc message container, the descending transmission channel type of descending logic channel mapping is T_TRRC_DL_TransportChannelType_dch, and transmission channel ID fills in the DCH ID that distributes the front.
Wherein, the professional corresponding descending transmission channel information cell of HSDPA among the Source RNC to Target RNC Transparent Container of rrc message container, transmission channel kinds extends this as TRRC_dch, and transmission channel ID fills in the DCH ID that distributes the front.
Wherein, the Source RNC to Target RNC Transparent Container of rrc message container need fill in the cell of Release4 structure, and other cell is all filled in according to the resource allocation of SRNC side.
If the DRNC under the Target cell is the Release5 version, then the cell in the message is prepared in the SRNC reorientation of filling in the Release5 structure according to resource allocation, sends reorientation and prepares message to CN.
If cell-of-origin, UE place does not have the HSPDA business, then the cell in the message is prepared in the SRNC reorientation of filling in the Release4 structure according to resource allocation, sends reorientation and prepares message to CN.
SRNC fills in the flow process fragment of RB reallocation message, and is specific as follows:
After SRNC received the reorientation message of CN, the resource allocation information of the RB message content in the rrc message container of the Release4 structure of coming according to DRNC band and the UE of own preservation was filled in the RB reallocation message of Release5 structure, is issued to UE then.
Wherein, SRNC judges the rrc message container cell of resolving the reorientation message of receiving, if the RB reallocation message of Release5 structure directly sends the RB reallocation message to UE.
If in the rrc message container be the RB reallocation message of Release4 structure, need to compare the resource information of RB reallocation message and SRNC preservation.If UE does not have the HSDPA business in the cell-of-origin, the RB reallocation message of filling in the Release5 structure according to the RB reallocation message of Release4 structure sends to UE.
If in the rrc message container be the RB reallocation message of Release4 structure, and UE has the HSDPA business in the cell-of-origin, if it is the professional interim DCH ID that distributes of HSDPA that SRNC is arranged in the transmission channel of descending deletion in the RB reallocation message, then in filling in the RB reallocation message of Release5 structure, do not fill in the transmission channel of this DCH ID in the transmission channel of descending deletion.
If in the rrc message container be the RB reallocation message of Release4 structure, and UE has the HSDPA business in the cell-of-origin, if all not having SRNC in the RB reallocation message in the transmitting channel information of the transmitting channel information of descending deletion and descending increase reprovision is the professional interim DCH ID that distributes of HSDPA, SRNC need add the transmitting channel information of DCH ID in the transmitting channel information of filling out to the descending increase reprovision of the RB reallocation message of the Release5 of UE so, and transmitting channel information needs the transmitting channel information filled in when bringing DRNC the same.
If in the rrc message container be the RB reallocation message of Release4 structure, and UE has the HSDPA business in the cell-of-origin, and SRNC need add the Mac-dFlow ID that original HSDPA business is distributed in the transmitting channel information of filling out to the descending deletion of the RB reallocation message of the Release5 of UE.
If in the rrc message container be the RB reallocation message of Release4 structure, and UE has the HSDPA business in the cell-of-origin, and SRNC fills out the RB reallocation message of the Release4 structure in the rrc message container that all brings according to DRNC to other resources in the RB reallocation message of the Release5 of UE and fills in.
RNC and CN have been described according to the consensus standard message interaction process in this part, and RNC and the UE flow process of carrying out reorientation alternately.
As shown in Figure 2, SRNC reorientation preparation flow process is as follows:
SRNC sends reorientation to CN and prepares message, and extends this as the resource allocation information of UE and be the professional interim parameters such as DCH information of distributing of HSDPA in the rrc message container of message;
CN issues SRNC reorientation message after receiving that message is finished in the reorientation resource allocation of DRNC, brings the RB reconfiguration message parameter of SRNC in the rrc message container of reorientation message for DRNC.
As shown in Figure 3, DRNC reorientation resource allocation flow process is as follows:
CN sends to DRNC reorientation resource allocation message after receiving that message is prepared in the reorientation of SRNC, is the SRNC side resource allocation information that brings DRNC in the rrc message container of reorientation resource allocation message;
After DRNC received the reorientation resource allocation message of CN, after DRNC was the success of UE Resources allocation, DRNC returned the reorientation resource allocation to CN and finishes message.
As shown in Figure 4, to reshuffle flow process as follows for the mutual RB of SRNC and UE:
SRNC sends the RB reallocation message to UE, and fills in RB relevant parameter information in message;
After UE receives the RB reallocation message,, after Target cell success synchronously, send the RB reprovision and finish message to Target cell according to parameter configuration in the RB reallocation message.
By above-mentioned method for relocating, when being reoriented to the RNC that only supports the Release4 version, the RNC of the Release5 version of supporting the HSDPA business is HSDPA traffic assignments DCH by SRNC temporarily, the resource information of the resource allocation conditions that DRNC is brought and oneself preservation compares the operation of filling in the RB reconfiguration message that sends to UE then, can effectively reduce the time delay that is reoriented to the DCH business of Release4 version from the HSDPA business of Release5 version, reduce unnecessary carrying out in advance professional time of HSDPA, improved the performance of system to the conversion of DCH Traffic Channel.
The above; only for the preferable embodiment of the present invention, but protection scope of the present invention is not limited thereto, and anyly is familiar with the people of this technology in the disclosed technical scope of the present invention; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection range of claim.
