Below with reference to drawings and the specific embodiments, the enforcement of technical solution of the present invention is described in further detail.
Embodiment one
Via node accesses Donor-eNB jurisdiction district, is in normal duty, at back haul link, Donor-eNB
Supervisory relay node as common subscriber equipment, for its increase, amendment or delete DRB configuration, for its increase, amendment,
Or delete measurement configuration, set up for it or release semi-persistent scheduling (Semi-Persistent Scheduling is called for short SPS),
The configuration (MAC-MainConfig) configuring MAC layer for it and the configuration that physical layer is special
(physicalConfigDedicated) etc., usual Donor-eNB is reconfigured by RRC connection and realizes this partial function.Above-mentioned
Configuration content may send in a configuration signal and be likely to a point a plurality of configuration signal transmission.
Judgement and the processing procedure of errors of backhaul link see Fig. 2, comprise the steps:
Step 210, when via node receive base station RRC connect reconfigure signaling after, if judging, this via node is not
All or part of configuration (unable to comply with (part of) that base station sends can be observed
Configuration), then it is assumed that and the back haul link generation wireless link error between base station, via node triggers base station to be implemented
RRC connection reconfigures.Via node starts an enumerator simultaneously, and (N can start value from 0, it is also possible to opens from 1 to be set to N
Beginning value), this enumerator represents that via node triggers RRC and connects the number information reconfigured.If N starts value from 0, in
It is N+1 time that the node that continues trigger RRC to connect the number of times reconfigured.
When the part sent when base station configures errorless, via node can use this part not made a mistake to configure；
Or via node is after judging the Radio Link Failure of back haul link, this is not used to reconfigure all of configuration ginseng in signaling
Number.If via node can observe the configuration of base station, then perform according to normal flow.
Via node can one of in the following ways trigger base station to be implemented RRC and connects and reconfigure:
1, via node has reconfigured signaling (RRCConnection by not sending response signaling such as RRC connection
Reconfiguration Complete) notify that this configuration of base station makes a mistake, now base station was configured in the scheduled time
Inside not receiving response, then give tacit consent to the configuration existing problems this time issued, base station needs to reconfigure the configuration parameter of this via node；
2, via node directly is implemented to reconfigure by RRC signaling triggering base station, and concrete RRC signaling may is that relaying
Node sends RRC connection reconfiguration request, RRC connection reconfigures triggering or RRC connects reconfiguration failure.Preferably, can be
Carrying the reason of this configuration failure in RRC signaling, the reason that concrete configuration is failed can be the one in following reason or many
Kind: the parameter of configuration is incorrect, the form of configuration information is incorrect, configuration in DRB do not exist, configure in SRB do not exist,
In configuration measure mark do not exist, configure in measurement object do not exist, configure in report configuration
(reportingconfiguration) not existence etc..
Step 220, base station sends RRC connection to via node and reconfigures signaling；
In this step, base station knows that being sent to the RRC of this via node before connects and reconfigure and make a mistake, then check
The problem that parameter in reconfiguring before oneself exists, revises configuration parameter therein, rear send new joining to via node
Put parameter.
If step 210 via node comprises the reason of configuration failure in RRC signaling, then base station can be the most former according to it
Because of the configuration parameter that amendment is corresponding, reconfigured by RRC connection and resend new configuration parameter to via node.Need explanation
, parameter therein may be made during propagated to produce mistake, if base station checks thinks that the parameter configured is
Correct, it is likely to there occurs mistake during propagated, base station can send configuration parameter again.
Such as, sometime, base station connects by RRC to reconfigure to send to via node increases the signaling of measuring task,
Including measuring mark, measure mark instruction measure object and association report configuration, owing to this measuring task is corresponding
Report configuration not definition (this is deleted again after reporting configuration not definition or definition), via node can not observe this
Configuration, via node sends RRC and connects reconfiguration request signaling, comprises the information of configuration failure wherein, notify base to base station
The reconfiguration failure of this newly-increased measuring task of standing.After base station obtains failed information, no longer send identical to via node
Configuration information, and detect to via node send RRC connect reconfigure the information comprised in signaling, revise mistake therein and join
Put, again send new configuration information to via node.
Step 230, via node receives after the RRC that sends base station connects and reconfigure signaling, and can relay node judges complete
Complete in accordance with configuration therein.If it is, forward step 240 to；Otherwise forward step 250 to.
Step 240, via node application RRC connects the configuration in reconfiguring, and resets or stops the meter starting in step 210
Count device or delete described enumerator.
Step 250, if via node still can not observe part or all of configuration therein, described enumerator adds 1, should
Enumerator reaches to trigger the thresholding reconfigured, and via node triggers RRC connection reconstruction flow process or via node directly discharges currently
RRC connect enter idle condition.
In the present embodiment, via node prevents triggering Reconfiguration Procedure from endless loop occur by arranging enumerator.This reality
Execute a permission via node in example and trigger a RRC connection Reconfiguration Procedure, it is impossible to continuous several times triggers RRC connection and reconfigures.
In actual applications, network can allow via node continuous trigger repeatedly RRC connection to reconfigure.The thresholding of such as this enumerator
It is configurable to 3 times or repeatedly, now, only reaches configuration when via node continuous trigger RRC connects the number of times reconfigured
Thresholding, via node just can trigger RRC connection reconstruction flow process or directly discharge current RRC connection entrance idle condition.
In the present embodiment, via node triggering RRC is connected the thresholding reconfigured and is configured by the predefined mode of agreement.
Embodiment two
Via node accesses the community under Donor-eNB, is in normal duty.Via node is in back haul link
Monitor base station send signal, base station for this via node be configured with AES (Ciphering Algorithm) and
Protection algorithm integrallty (Integrity Protection Algorithm).At back haul link, as receiving terminal, via node
Need to calculate X-MAC (Computed MAC-I, the calculating of packet PDU (Protocol Data Unit, protocol Data Unit)
Message integrity verification code), if the MAC-I (Message in the corresponding data bag of the X-MAC and the reception that calculate
AuthenticationCode for Integrity, message integrity verification code) be consistent, then prove that integrity protection is
Successfully, otherwise prove unsuccessful.
The parameter of X-MAC is calculated, including enumerator COUNT value, directioin parameter by via node or terminal maintenance
(DIRECTION), radio bearer identification (BEARER), key (Key i.e. KRRCint) etc..Wherein COUNT value is by HFN (Hyper
Frame Number, Hyper Frame Number) and PDCP SN (PacketData Convergence Protocol Sequence
Number, packet data convergence protocol serial number) constitute.
Judgement and the processing procedure of the errors of backhaul link of the present embodiment see Fig. 3, comprise the steps:
Step 310, relay node judges wireless link makes a mistake, and triggers base station by RRC signaling and implements RRC connection weight
Configuration, comprises, in this RRC signaling, the reason that integrity protection is failed；
After via node receives packet, judge that the data integrity protection that base station issues loses according to the content of packet
Lose, then it is assumed that and the back haul link generation wireless link error between base station, via node often receives packet and carries out a secondary data
The inspection that whether failed integrity protection is.When the X-MAC of the packet of relay node judges calculating is consistent with the MAC-I of reception,
Then think that data integrity protection is successful, otherwise it is assumed that failure.
Via node triggers the RRC signaling implementing to reconfigure in base station and specifically may is that via node sends RRC connection and heavily joins
The request of putting, RRC connect reconfigure triggering, RRC connects reconfiguration failure, or other RRC signaling.
Preferably, in this RRC signaling in addition to comprising the reason that integrity protection is failed, it is also possible to comprise integrity protection
The identification information of the RAB that failure is corresponding.Owing to now up-link is no problem, via node can edge
With original protection algorithm integrallty to base station transmission RRC signaling.
Moreover it is preferred that in this step, via node will start an enumerator, and (N can be from the beginning of 0 to be set to N
Value, it is also possible to start value from 1), this enumerator represents that via node triggers RRC and connects the number information reconfigured.As
Really N starts value from 0, and it is N+1 time that via node trigger RRC to connect the number of times reconfigured.
Step 320, base station sends RRC connection to via node and reconfigures signaling；
Base station, after knowing integrity protection failure, returns to via node and new reconfigures signaling, wherein can comprise
The configuration parameter of the protection algorithm integrallty reconfigured, such as the COUNT value reseted, or new protection algorithm integrallty (base station
Reconfigure Integrity Protection Algorithm) etc..It should be noted that owing to via node has been detected by
The integrity protection failure of downlink, in order to ensure that the connection of step RRC reconfigures the accurate delivery of signaling, base station should in calculating
During the MAC-I of signaling and via node is when calculating the X-MAC of this signaling, parameter therein such as enumerator COUNT value, direction
Parameter, radio bearer identification, key (KRRCint) all use predefined value；Or, base station and via node both sides weigh simultaneously
If COUNT value, now, then need not be notified these parameters of via node by base station；Or, via node triggers base station to be implemented
The Article 1 RRC signaling that RRC connects after reconfiguring does not uses protection algorithm integrallty.
Step 330, via node receive RRC connect reconfigure signaling after, relay node judges can completely observe wherein
Configuration, if it is, forward step 340 to；Otherwise forward step 350 to；
Step 340, via node application RRC connects the configuration in reconfiguring, and resets or stops the meter starting in step 310
Count device or delete described enumerator；
Step 350, if via node still can not observe part or all of configuration therein, described enumerator adds 1, should
Enumerator reaches to trigger the thresholding reconfigured, and via node triggers RRC connection reconstruction flow process or via node directly discharges currently
RRC connect enter idle condition.
In the present embodiment, via node prevents triggering Reconfiguration Procedure from endless loop occur by arranging enumerator.This reality
Execute a permission via node in example and trigger a RRC connection Reconfiguration Procedure, it is impossible to continuous several times triggers RRC connection and reconfigures.
Via node triggering RRC is connected the thresholding reconfigured and is configured by the predefined mode of agreement.
