Abstract
When the radio net controller (RNC) finds out lost synchronization of the comm. link between the user end (UE) and the service cell NodeB, RNC reconfigures asynchronously NodeB to complete the resource reconfiguration of the radio link. Via RADIO LINK RECONFIGURATION REQUEST MESSAGE, RNC sends reconfigured physic parameters to NodeB. After the reconfigured data become effective, NodeB sends back the RADIO LINK RECONFIGURATION RESPONSE message. Via the non-synchronization procedure of radio link, this invention completes the protocol interaction between RNC and NodeB; further completes the reconfiguration of physic layer parameters of NodeB. The aim of configuring fast and effectively the radio link physic resource is reached. The radio link losing synchronization restores rapidly to the synchronization state.
Description
Technical field
The present invention relates to the communications field, relate in particular to the method for recovering again behind the Radio Link Failure.
Background technology
In the TD-SCDMA communication system, when user (UE) communicates with network side, exist at present owing to the link-quality difference link failure takes place and then causes that the incident that communications is obstructed takes place.After the user detects the down wireless link failure, can carry out one time cell reselection process usually, and send cell update message in the sub-district of choosing.If the cell update that UE still reports Radio Link Failure to cause from the common signal channel of former Serving cell illustrates that then the signal quality of former Serving cell is better, need be to NodeB (Serving cell) and UE reprovision parameter, the communication on the recovery Radio Link.
See also Fig. 1, it is the flow chart of existing down link failure back wireless link re-recovering.It comprises: at first, after UE detects the down wireless link failure, the cell update (CELL UPDATE) that reports Radio Link Failure to cause from the common signal channel of former Serving cell, then, RNC makes a strategic decision out by measurement report and algorithm needs to adjust physical resource, and use the synchronized reconfiguration process that NodeB and UE are carried out the parameter renegotiation configuration: RNC sends RADIO LINK RECONFIGURATIONPREPARE (radio link reconfiguration preparation message) to Serving cell NodeB earlier, requires NodeB to finish the configuration set-up procedure of the Radio Link of communicating by letter with UE; NodeB is after finishing the configuration set-up procedure of the Radio Link of communicating by letter with UE, return the ready RADIO LINK of its Radio Link RECONFIGURATIONREADY (the ready message of radio link reconfiguration) to RNC, subsequently, RNC sends RADIO LINK RECONFIGURATIONCOMMIT (radio link reconfiguration submission message) and sends CELL UPDATECONFIRM (cell update acknowledge message) to UE to NodeB after receiving the ready message of radio link reconfiguration.
Synchronised radio link reconfigure is engraved in when requiring coming into force of reprovision parameter and keeps among NodeB and the UE synchronously, just synchronized radio link reconfiguration procedure requires the NodeB reconfiguration parameters to come into force constantly and UE stresses configuration parameter moment of coming into force and is consistent, be activationary time (the Activation time in the reconfiguration message on the Uu interface, be that parameter comes into force constantly) should be set to identical value with the CFN (Connection Frame Number) in the RADIO LINKRECONFIGURATION COMMIT message (radio link reconfiguration submission message), NodeB and UE reprovision parameter synchronization come into force on the assurance wave point, avoid the transmission course loss of data.That is to say, being engraved in NodeB during the new configuration take-effective of synchronized reconfiguration process receives after the RADIO LINK RECONFIGURATION COMMIT message and arrives the CFN time point and just come into force, the CFN time point is difficult to estimation accurately, can not guarantee that NodeB new configuration after receiving RADIO LINKRECONFIGURATION COMMIT message comes into force, also just can not activate the new configuration of Radio Link immediately, inevitably prolong the out of alignment time of Radio Link thus.
Under the situation of Radio Link Failure, RNC wishes as early as possible the resource of Radio Link to be reshuffled and come into force, and shortens the time of radio link failure as far as possible, and then avoids UE to go offline because of Radio Link Failure.Yet, above-mentioned wireless link re-recovering method utilizes synchronised radio link reconfigure to carry out link-recovery, because NodeB and UE reprovision parameter synchronization come into force on the needs assurance wave point, therefore the inevitable out of alignment time that prolongs Radio Link, and then increase the probability that UE goes offline because of the Radio Link Failure overlong time.
Summary of the invention

RNC knows that by following steps described radio link failure: RNC receives UE and receives the described Radio Link Failure message that NodeB reports from cell update or the RNC that the common signal channel of former Serving cell reports Radio Link Failure to cause.
The present invention also comprises: RNC finishes resource reconfiguration to the UE side by the cell update acknowledge message.
RNC carries out asynchronous reshuffling further to NodeB and comprises: RNC issues NodeB by the physical parameter that radio link reconfiguration request message RADIO LINK RECONFIGURATION REQUEST will need to dispose; After the NodeB configuration data comes into force, return radio link reconfiguration response message RADIO LINK RECONFIGURATION RESPONSE.
Having added the up sign indicating number that needs increase in radio link reconfiguration request message divides combination channel attribute field UL CCTrCH ADD IE, needs the descending sign indicating number of increase to divide combination channel attribute field DLCCTrCH Add IE.
In radio link reconfiguration request message, also can increase initial downlink through-put power field Initial DLTransmission Power IE.
Divide combination channel attribute field UL CCTrCH Modify IE to expand to the up sign indicating number that needs in the radio link reconfiguration request message to revise, increase son field " DPCH Add ", " DPCH Modify ", " DPCH Delete ".

Embodiment
Below in conjunction with accompanying drawing, specify the present invention.
Core of the present invention is, finish protocol interaction between RNC and NodeB by the asynchronous process of Radio Link, and then the physical layer parameter of finishing NodeB is reshuffled, reach the purpose of collocation wireless link physical resource rapidly and efficiently, make the Radio Link that is in desynchronizing state recover synchronous regime as early as possible.
The invention discloses a kind of method of wireless link re-recovering, it comprises: after RNC is known user terminal UE and radio link failure that Serving cell NodeB communicates by letter, RNC carries out asynchronous reshuffling to Serving cell NodeB, to finish the resource reprovision to described Radio Link.
After RNC can know that a certain radio link failure: UE detects the down wireless link failure that is connected with NodeB by dual mode at least, and the cell update that still reports Radio Link Failure to cause from the common signal channel of former Serving cell, after perhaps NodeB detects the up-link wireless link failure of communicating by letter with a certain UE, report this Radio Link Failure message of RNC.
RNC can finish protocol interaction between RNC and NodeB by asynchronous mode, and RNC issues NodeB with the new physical parameter of a cover, to finish the resource reprovision to this Radio Link.The characteristics of this process are that configuration can come into force for the data instant of NodeB, guarantee the fast quick-recovery of Radio Link as far as possible, reduce the possibility that Radio Link goes offline.
With next instantiation the present invention is described.
See also Fig. 2, it is the realization flow figure of the example of wireless link re-recovering of the present invention.It comprises:
S11: when user terminal UE detects down wireless link when failure, the cell update message (CELL UPDATE) that reports Radio Link Failure to cause from the common signal channel of former Serving cell.
S12:RNC issues NodeB by the physical parameter that radio link reconfiguration request message (RADIO LINKRECONFIGURATION REQUEST) will need to dispose.
S13:NodeB returns radio link reconfiguration response message (RADIOLINK RECONFIGURATION RESPONSE) to RNC after the data that dispose are come into force.
S14:RNC finishes resource reconfiguration to the UE side by the cell update acknowledge message.
UE monitor and NodeB between down wireless link when failure, if the cell update that the common signal channel of UE by this sub-district reports Radio Link Failure to cause, this moment, UE and NodeB can not obtain down-going synchronous, the dedicated channel of distributing for UE can not be used to transmit the RRC signaling, RRM (RRM) makes a strategic decision out by measurement report and algorithm to be needed to adjust physical resource, so that NodeB and UE can obtain in new configuration synchronously.
RADIO LINK RECONFIGURATION REQUEST/RESPONSE is a standard procedure of 3GPPNBAP agreement (the Node B application protocol of third generation communication system), and a wireless links is carried out asynchronous reshuffling.This process is mainly used in issues Nodeb with a cover new argument, to finish the resource reprovision to RL (Radio Link).The characteristics of this process are that configuration can come into force for the data instant of NodeB, and protocol procedures is simple, saved a submission process, but shortcoming is to guarantee the radio-resource-configuration of NodeB and the configuration synchronization of UE, may cause NodeB in configuration 1, to send out data in other words, and UE prepares to accept in configuration 2, in normal processes, may cause losing of data.The inventor considers: guaranteeing (because failure has appearred in link, loss of data is inevitable) under the situation that data are not lost, should utilize the quick of this process, characteristics of high efficiency guarantees the fast quick-recovery of conversation as far as possible.
In order to guarantee that physical parameter is very intactly disposed to NodeB, can be with the RADIO LINK RECONFIGURATION REQUEST message in the 3GPP agreement, such as, the parameter in the RADIO LINK RECONFIGURATION PREPARE message of existing synchronous layoutprocedure is added RADIO LINK RECONFIGURATION REQUEST message.The Radio Link physical parameter that the present invention can also will be referred to is adjusted, as resource parameters such as time slot, code channel, channel are sent to NodeB by RNC by RADIO LINK RECONFIGURATION REQUEST message again, enable new configuration by NodeB.
With reference to existing synchronized reconfiguration process, the present invention has added the up sign indicating number that needs increase and has divided combination channel attribute field UL CCTrCH ADD IE, needs the descending sign indicating number of increase to divide combination channel attribute field DL CCTrCH Add IE in radio link reconfiguration request message.
In the wireless link re-recovering process, consider may exist the DPCH channel to adjust or newly-increased situation, in radio link reconfiguration request message, can add initial downlink through-put power field InitialDL Transmission Power IE.When the DPCH channel adjusts or increases newly,, reach the purpose that improves power control efficient by the Radio Link power control initial value that initial downlink through-put power field is informed NodeB.Certainly, initial downlink through-put power field can not added yet, even have under the situation of adjusting or increasing newly at DPCH, controls the initial value that (closed-loop control, open loop control etc.) also obtain power control at existing power, reaches the reduction effects of jamming.
In addition, divide combination channel attribute field UL CCTrCH Modify IE to expand to the up sign indicating number that needs in the radio link reconfiguration request message to revise, increase son field " DPCH Add (DPCH increase) ", " DPCH Modify (DPCH modification) ", " DPCH Delete (DPCH deletion) ".And, divide combination channel attribute field DL CCTrCHModify IE to expand to the descending sign indicating number that needs in the radio link reconfiguration request message to revise, increase son field " DPCH Add ", " DPCH Modify ", " DPCHDelete ".
And, for can compatible multifrequency point communication system, in radio link reconfiguration request message, also can expand UARFCN (frequency) IE, in order to the center frequency point value of notice wireless transmission in the multifrequency point communication system.This IE can expand the back (as table 1) in radio link reconfiguration request message, but the position that this IE expanded is not limited thereto.
