Description
Technical field
The present invention relates to communication technical field, relate in particular to processing method and the system of a kind of RLF.
Background technology
As shown in Figure 1, E-UTRAN is comprised of evolved base station (evolved Node B, eNB) network architecture of Evolved UTRAN (Evolved Universal Terrestrial Radio Access, E-UTRAN).ENB completes Access Network function, passes through air interface communication with subscriber equipment (User Equipment, UE).Between UE and eNB, not only exist chain of command to be connected but also exist user's face to connect.For each, be attached to the UE of network, by a Mobility Management Entity (Mobility Management Entity, MME), for it provides service, between MME and eNB, adopt control plane S1 interface (S1 for the control plane, S1-MME) to be connected.S1-MME interface, for UE provides chain of command service, comprises mobile management and bearer management function.Between S-GW and eNB, adopt user plane S1 interface (S1 for the user plane, S1-U) to be connected, the UE that is attached to network for each, has a S-GW to provide service for it.S1-U interface provides the service of user's face for UE, and the user face data of UE is carried between S-GW and eNB and is transmitted by S1-U.
In existing hierarchical network as shown in Figure 2, macro base station (note is Macro eNB) provides basis to cover, lower powered small base station (being referred to as Local eNB herein) provides focus to cover, between Local eNB and Macro eNB, have data/signaling interface (can be wired or wireless interface), UE can be operated under Macro eNB or Local eNB.The cell coverage area of controlling due to Local eNB is little, and the UE of service is few, so the UE that is connected to Local eNB often can obtain better service quality, as: obtain higher service rate, higher-quality link.Therefore,, when being connected to the UE of Macro eNB and entering the coverage of the corresponding community of Local eNB, can transfer to the service that Local eNB provides to obtain Local eNB; When UE is during away from the corresponding cell coverage area of Local eNB, need to transfer to the community that Macro eNB controls, to keep wireless connections.
The network architecture shown in Fig. 2 can support user to carry separation.In Macro eNB community and Local eNB community, when overlapping covered, can will under the different base station of being carried on of corresponding UE, dispatch and transmit.Especially, below, to realizing user's face (UP), give an example with the separated network architecture of chain of command (CP).Under which, when UE is in the region of only having Macro eNB community to cover, the chain of command of UE connects and is connected with user's face all at Macro eNB, when UE moves to/approach Macro eNB community and Local eNB community when overlapping covered, UE user plane bearer (all or part of) connection is transferred to Local eNB, to obtain higher service transmission rate; Chain of command connection still remains on Macro eNB, the signaling consumption bringing to reduce frequent switching.
Whether, in existing protocol, UE is used the determination methods of two constant N 310, N311 and timer T310 combinations, detect air interface wireless link and go wrong:
When UE is in Radio Resource control connection during RRC_CONNECTED state, physical layer is constantly measured the down channel quality of Serving cell, place, when channel quality being detected lower than a certain thresholding, to rrc layer, send " out-of-sync " indication, when channel quality being detected higher than a certain thresholding, to rrc layer, send " in-sync " indication.
When receiving N310 continuous " out-of-sync " indication, and when timer T300, T301, T304 and T311 do not open, the rrc layer of UE judges that now problem has temporarily appearred in radio link quality, opening timing device T310, the maximum permission time that this timer recovers for controlling radio link quality.When " in-sync " indication of receiving that N311 is continuous, and timer T310 has been when opened, and the rrc layer judgement radio link quality of UE is restored, and stops timer T310.
When UE detects following any one situation and occurs, think and Radio Link Failure (RLF) detected:
(1) timer T310 is overtime;
(2) receive the random access failure indication of MAC layer;
(3) maximum retransmission that reaches of receiving rlc layer is indicated.
Now, if the safety of Access Layer does not also activate, UE will discharge RRC and connect, and enter RRC_IDLE state; Otherwise UE initiates RRC connection reconstruction process.
According to present agreement, UE is only used a resource under base station, once UE detect timer T310 overtime or receive the random access failure indication of MAC layer or receive rlc layer reach maximum retransmission indication, the processing of Radio Link Failure is initiated in capital: discharge RRC and connect, or initiate RRC connection reconstruction process.And scene to a plurality of base station cells of UE polymerization resource, particularly to carrying the situation of separation (especially CP/UP is separated), even if Local has met the conditions such as timer T310 is overtime, because connecting, RRC may maintain Macro eNB, UE is connected with RRC between Macro eNB should be not influenced, therefore should not initiate by existing protocol the processing procedure of RLF.That is, how the lower Local RLF of the scene of a plurality of base station cells of user's polymerization resource (particularly carrying the separated network architecture) is processed, prior art does not also provide scheme.

Provide the explanation of several specific embodiments below.
Specific embodiment one: for the Local RLF of UE, separated (as Local eNB does not the possess RRC function) scene of the carrying based on CP/UP separation below describes.
Referring to Fig. 5, step S301:UE finds the Local RLF for UE;
Under the scene of CP/UP separation, for each Local community that maintains UE radio bearer, when meeting one of following situation, UE thinks Local RLF, and reports indication to the RRC entity of UE:
(1) if UE detects physical layer link quality problems corresponding to this Local community, and the T310 timer expiry of this Local community;
(2) corresponding UE side MAC layer entity indication Local RA failure;
(3) corresponding UE side RLC entity, when the transmission of certain AMD PDU or its fragment reaches RLC maximum retransmission.
Especially, in CP/UP separation process, if UE cannot obtain the uplink synchronous with Local eNB by random access procedure all the time within a period of time, by the respective handling of carrying after shifting unsuccessfully.
Step S302:UE reports Local RLF by Macro cell;
UE, after finding Local RLF, stops uplink and data processing that UE carrying on all Local eNB; And Local RLF(be can further include to the reason of RLF) report Macro eNB.This message can or be reused other RRC message and realize by the new RRC message defining, and reports by Macro cell.
Typical scene may comprise several as follows:
(1) Macro eNB only with Local eNB polymerization, and under Local eNB, only have a Local community that maintains UE radio bearer;
(2) Macro eNB only with Local eNB polymerization, and under Local eNB, there is the Local community of a plurality of UE of maintaining radio bearers;
(3) Macro eNB and a plurality of Local eNB polymerization, and Macro to the processing policy of Local RLF for all Local eNB.
Step S303:Macro eNB processes Local RLF, and processing policy is informed to Local eNB;
Macro eNB receives after the Local RLF information that UE reports, and according to situations such as current measurement result, the network carryings, judges, determine to initiate CP/UP merging process or and another one local eNB between heavily separation process of CP/UP.So-called heavy separated, the RB first CP/UP separation process being shifted is transferred back to Macro eNB, then by new CP/UP separation order, by part/all RB transfers to another one Local eNB again; Or by the part originally shifting/all RB directly transfers to another one LocaleNB.
If Macro determines to initiate CP/UP merging process:
(1) whether Macro eNB indication Local stops transfer of data and the processing of this UE under Local and (indicates the relevant radio-resource-configuration of mutual this UE of Local eNB to depend on whether Macro has still preserved relevant configuration information, if indication Local eNB intercorrelation wireless resource configuration, Local eNB carries out the information interaction of corresponding radio-resource-configuration between eNB);
(2) Macro eNB sends DRB transfer command to UE, and indication UE transfers to Macro eNB by DRB from Local eNB;
(3) UE receives after DRB transfer command, and the MAC that deexcitation is corresponding with Local eNB and PHY entity recover CP/UP separation MAC and PHY configuration before; And shifted order to Macro eNB transmission DRB;
Or,
(1) Macro eNB sends CP/UP combine command, and indication Local stops transfer of data and the processing of this UE under Local;
(2) Local eNB receives after this order, stops corresponding transmission, and feeds back RB relevant information, processes wireless resource configuration;
(3) Macro eNB, according to the feedback of Local eNB, carries out acceptance judging, if can receive, and (PDCP)/RLC/MAC entity of so direct reprovision Macro eNB, otherwise directly notify Local eNB and UE to discharge this carrying;
(4) Macro eNB sends DRB transfer command to UE, and indication UE transfers to Macro eNB by DRB from Local eNB;
(5) UE receives after DRB transfer command, and the MAC that deexcitation is corresponding with Local eNB and PHY entity recover CP/UP separation MAC and PHY configuration before; And shifted order to Macro eNB transmission DRB.
If Macro determines to initiate heavily separation process of CP/UP (DRB directly shifts):
(1) Macro eNB indication Local stops the transfer of data of this UE under Local and processing (whether indicating the wireless resource configuration of mutual this UE of Local eNB to depend on that Macro is whether for new Local eNB provides relevant configuration information); If Macro does not indicate Local eNB to carry out the mutual of resource allocation information, Macro eNB sends the relevant wireless resource configuration of this UE to new Local eNB, otherwise the Local eNB of generation RLF sends the relevant wireless resource configuration of this UE to Macro or new Local eNB by the interface between base station;
(2) Macro eNB is designated as Local eNB2 to the another one Local eNB(of polymerization) send CP/UP separation order, to need Local eNB2 be the reserved Radio Resource of UE by Macro eNB or Local eNB1 alternately to Local eNB2;
(3) Local eNB2 replys the separated confirmation order of Macro eNB carrying to Macro eNB;
(4) Macro eNB receives after the positive response of Local eNB2, to UE, sends DRB transfer command;
(5) UE receives after DRB transfer command, with synchronizeing of Local eNB2, and has shifted order to Macro eNB transmission DRB.
If heavily separation process of CP/UP (separated after first merging) is initiated in Macro eNB decision: first initiate CP/UP merging process, then the CP/UP separation process between initiation and another one Local eNB.
If arbitrary carrying that Macro eNB can not receive Local eNB according to situation judgements such as current measurement result, the network carryings, indicates UE and Local eNB to discharge relevant carrying.In addition, UE and Local eNB can introduce a Timer separately, for the treatment of the wireless resource configuration retaining separately.
Explanation, in step S303, except above-mentioned Macro eNB indication Local eNB stops the complete control program of Macro of transfer of data, can also take Macro eNB only to inform problem, do not indicate Local eNB how to process, and by Local eNB, stopped voluntarily the scheme of transfer of data.
Specific embodiment two: the problem Local cell(corresponding for UE maintain UE radio bearer, and the Local community of generation Local RLF), separated (as Local eNB does not the possess RRC function) scene of the carrying based on CP/UP separation below describes.
Referring to Fig. 6, step S401:UE finds for corresponding problem Local cell
Under the scene of CP/UP separation, for each Local community that maintains UE radio bearer, when meeting one of following situation, UE thinks that Local RLF occurs the Local cell that maintains UE radio bearer, and reports the RRC entity of indicating to UE:
1) if UE detects physical layer link quality problems corresponding to this Local community, and the T310 timer expiry of this Local community;
2) corresponding UE side MAC layer entity indication Local RA failure;
3) corresponding UE side RLC entity, when the transmission of certain AMD PDU or its fragment reaches RLC maximum retransmission.
Especially, in CP/UP separation process, if UE cannot obtain the uplink synchronous with Local eNB by random access procedure all the time within a period of time, by the respective handling of carrying after shifting unsuccessfully.
Step S402:UE reports Local RLF by Macro cell;
UE, after finding Local RLF, stops uplink and the data processing of UE on the auxiliary cell of problem Local cell and this Local cell; And Local RLF and problem Local cell sign (can further include the reason of RLF) are reported to Macro eNB.This message can or be reused other RRC message and realize by the new RRC message defining, and reports by Macro cell.
Typical scene may comprise several as follows:
(1) Macro eNB only with Local eNB polymerization, and under Local eNB, there is the Local community of a plurality of UE of maintaining radio bearers, and Macro to the processing policy of Local RLF only for problem Local community;
(2) Macro eNB and a plurality of Local eNB polymerization, and Macro to the processing policy of Local RLF only for the Local community that maintains UE radio bearer that RLF occurs.
Step S403:Macro eNB informs that the Local cell of corresponding its polymerization of Local eNB goes wrong, and Local carries out respective handling;
After Macro eNB receives that UE reports, the Local RLF that UE is reported and problem Local cell inform Local eNB.Local eNB, after receiving the mutual message of Macro eNB, stops scheduling, transmission and data processing to this UE correspondence on the auxiliary cell of correspondence problem Local cell and this problem Local eNB.In addition, this Local eNB merges to Macro eNB(correspondence CP/UP) the heavy separation of the corresponding CP/UP of/other Local eNB() mutual wireless resource configuration corresponding to DRB of transmitting on problem Local cell.The wireless resource configuration of the RB that on this Local eNB, the problem Local cell of reservation is corresponding can directly discharge, also can the overtime rear release at the timer of self maintained.
Step 404:Macro eNB is according to situations such as current measurement result, the network carryings, initiates to this UE the CP/UP merging process at RB corresponding to correspondence problem Local cell, or and another one local eNB between heavily separation process of CP/UP.In addition, if corresponding RB is used RLC AM mode transfer,, from the angle of data lossless transmission, Local eNB can or not send successful downlink data the upper untreated complete upstream data of DRB corresponding to this UE yet, and transferring to follow-uply provides on the base station of respective service for this UE.
Meanwhile, Macro eNB initiates to merge or heavily separation process for the CP/UP of corresponding RB (s):
If Macro eNB initiates the CP/UP merging process for corresponding RB (s):
(1) Macro eNB sends the transfer command for corresponding DRB (s) to UE, and it is transferred to Macro eNB from Local eNB;
(2) UE receives after described transfer command, revises the MAC corresponding with the affiliated Local eNB of problem Local cell and PHY physical arrangements and MAC and the PHY physical arrangements corresponding with Macro eNB, and has shifted order to Macro eNB transmission DRB.
If Macro determines to initiate the heavily separation process of CP/UP (RB directly shifts) for corresponding RB (s):
(1) Macro eNB is designated as Local eNB2 to the another one Local eNB(of polymerization) send CP/UP separation order, the RB configuration information that need to be carried by Local eNB2 is given Local eNB2 alternately by Macro eNB or Local eNB1;
(2) can Local eNB2 carry the relevant issues RB of this UE according to factor judgements such as receiving control, if can, to Macro eNB, reply Macro eNB carrying separation and confirm order;
(3) Macro eNB receives after the positive response of Local eNB2, to UE, sends the RB transfer command for corresponding RB, is transferred to Local eNB2;
(4) UE receives after RB transfer command, activate the special-purpose PHY of the RB corresponding with Local eNB2, MAC entity, realization is synchronizeed with Local eNB2's, revises the special-purpose PHY of the RB corresponding with Local eNB1, MAC entity, and has shifted order to Macro eNB transmission RB.
If the heavily separation process of CP/UP (separated after first merging) for corresponding RB is initiated in Macro eNB decision: first initiate the CP/UP merging process for corresponding RB, then the CP/UP separation process between initiation and another one Local eNB.
If Macro eNB can not receive the arbitrary carrying on problem cell according to situation judgements such as current measurement result, the network carryings, indicate UE and Local eNB to discharge relevant carrying.In addition, UE and Local eNB can introduce a Timer separately, for the treatment of the wireless resource configuration retaining separately.
Illustrate, except the indication problem only of the Macro eNB described in the present embodiment, the scheme that Local eNB carries out respective handling is, can also adopt similar to Example 1ly, and how Macro eNB judgement is processed, and informs the scheme how Local eNB operates.
