In order to reduce the manual intervention to network, O＆M cost is reduced, while improving the performance and stability of network, third
For Partnership Program (Third Generation Partnership Projects, 3GPP) group be woven in the general land of evolution without
The version of line access (Evolved Universal Terrestrial Radio Access Network, E-UTRAN) system
This 8 (Release-8) starts to introduce self-organizing network (Self-Organized Network, SON) function.E-UTRAN includes
Evolution base station (evolved Node B, eNB), corresponding core net (Core Network, CN) includes mobile management entity
(Mobile Management Entity, MME) and gateway (Serving Gateway, S-GW) etc..ENB and MME/S-
It is connected by S1 interfaces between GW, can be connected by X2 interface between eNB.One eNB can manage one or more cells
(Cell).SON includes moving load balance optimizing (Mobility Load Balancing optimization, MLB), moves
The contents such as dynamic robustness optimization (Mobility Robustness Optimization, MRO).
MRO includes to switching (Too Late Handover), too early switching (Too Early Handover), mistake too late
The accidentally detection of cell switching (Handover to Wrong Cell) scene, analyzes and counts the result detected, counts
Number reach the mobility parameters after certain amount between relevant neighboring community and hold consultation the contents such as adjustment, cut with reducing
Change unsuccessfully (Handover Failure, HOF) or the relevant Radio Link Failure (Radio Link Failure, RLF) of switching.
Detection for MRO scenes is mainly receiving wireless heterogeneous networks reconstruction trial (RRCre- according to eNB
Establishment attempt, wherein RRC is the abbreviation of Radio Resource Control) or Radio Link Failure report
It accuses Radio Link Failure instruction (RLF INDICATION) message sent out after (RLFReport) and eNB is being received
Handover report (HANDOVER REPORT) message that is sent out after RLFINDICATION message judges and notifies.UE is having
When RLF Report need report, it can be completed in RRC connection re-establishments
(RRCConnectionReestablishmentComplete) or RRC connections are established and are completed
(RRCConnectionSetupComplete) instruction is carried in message to notify eNB, eNB that can be asked by user equipment information
(UEInformationRequest) message asks UE to report RLF Report, and then UE is responded by user equipment information
(UEInformationResponse) message reports the RLF Report to eNB.
As shown in Figure 1 for example, connection failure has occurred in cell 1 in user equipment (User Equipment, UE)
(HOF or RLF) then carries out RRC in cell 2 and rebuilds trial.Cell 2 receives RRC and rebuilds after trial message according in message
Content may know that connection failure has occurred in UE in cell 1, then to cell 1 send RLF INDICATION message.Cell 1
Receive after RLF INDICATION message according to the content in message may know that UE had occurred in cell 1 connection failure and
RRC has been carried out in cell 2 rebuilds trial.At this moment, cell 1 can inquire the context of its preservation, if it find that the UE is just by small
1 tangential cell 2 of area, then it can determine that for this be once from cell 1 to the switching too late of cell 2, the cell-of-origin for initiating switching is
Cell 1 (i.e. oneself), so without hair HANDOVER REPORT message；If it find that the UE is just by 2 tangential cell 1 of cell
, then it can determine that for this be once from cell 2 to the too early switching of cell 1, the cell-of-origin for initiating switching is cell 2, so wanting
HANDOVER REPORT message is sent out to cell 2, primary switching too early is had occurred with notifying cell 2；If it find that the UE be just by
The tangential cell 1 (different from cell 1 and cell 2) of cell 3, then can determine that as this it is once to be cut from cell 3 to the mistake of cell 1
It changes and (cell 2 should be switched to), the cell-of-origin for initiating switching is cell 3, so to send out HANDOVER REPORT to cell 3
Primary mistake switching has occurred with notifying cell 3 in message.
Alternatively, connection failure has occurred in cell 1 in UE, subsequently into Idle state (idle), subsequently within the cell 4
RRC is carried out to be successfully established.Cell 4 gets and may know that UE has occurred in cell 1 according to content therein after RLF Report
Connection failure then sends RLF INDICATION message to cell 1, and carries the content in RLF Report and indicate to be somebody's turn to do
RLF Report establish the instruction of (rather than RRC connection reconstructions) from RRC connections.Cell 1 receives RLF INDICATION and disappears
After breath, find containing the RLF Report after RRC connections foundation in message, it can thus according to the content in RLF Report
Know that connection failure has occurred in UE in cell 1, RRC has also been carried out in which cell and has rebuild trial (it is assumed that being small
Area 2), which (it is assumed that being cell 3) cell-of-origin which switches is, the last time switching is initiated to connection to lose
The time lost is how many, which is HOF or RLF, and wireless measurement when generation connection failure is as a result, connect
Location information etc. when connecing unsuccessfully.At this moment, cell 1 can be judged (here first according to the content understood from RLF Report
Assuming that can determine that the connection failure is RLF according to relevant information in RLF Report, and it is related to the last switching, and occur
The reason of RLF is MRO problems rather than covering problem), if it find that cell 3 be equal to cell 1, then can determine that for this be once from
Cell 1 arrives the switching too late of cell 2, and the cell-of-origin for initiating switching is cell 1 (i.e. oneself), so without hair HANDOVER
REPORT message；If it find that cell 3 is equal to cell 2, then can determine that for this be once from cell 2 to the too early switching of cell 1,
The cell-of-origin for initiating switching is cell 2, so to send out HANDOVER REPORT message to cell 2, is had occurred with notifying cell 2
Primary switching too early；If it find that cell 3 is other cells different from cell 1 and cell 2, then can determine that for this be once from
Cell 3 is to the mistake switching (should be switched to cell 2) of cell 1, and the cell-of-origin for initiating switching is cell 3, so will be to small
HANDOVER REPORT message is sent out in area 3, and primary mistake switching has occurred with notifying cell 3.
It is belonging to cell when above-mentioned RLF INDICATION message, the specific implementation of HANDOVER REPORT message

The MRO scenes being able to detect that in the embodiment of the present invention can there are many, common MRO scenes include following three
One of：Switching too late, too early switching and wrong cell switching.According to network environment and the difference of switching mode, MRO
Also there is likely to be other types for scape, as the case may be depending on.
Flow as shown in Figure 2, before step S202, the cell-of-origin to switch needs first to determine the MRO scenes of detection
Type, it is contemplated that the cell-of-origin to switch will receive HANDOVER REPORT message, and then be disappeared according to HANDOVERREPORT
Content in breath determines the type of MRO scenes, it is therefore possible to use following judgment mode determines MRO scenes：
When the cell-of-origin to switch receives HANDOVER REPORT message, this MRO scene for needing to detect is determined
For switch too early or wrong cell switching, wherein carry CRE relevant informations in HANDOVER REPORT message.
After HANDOVER REPORT message, the cell-of-origin that switches can also receive RLF INDICATION and disappear
Breath, can judge MRO scenes according to the message at this time：
According to the RLF INDICATION message received, the MRO scenes confirmly detected are for the cell-of-origin to switch
Switch too late, wherein carry CRE relevant informations in RLF INDICATION message.
Mentioned above, the cell-of-origin to switch can determine MRO scenes according to HANDOVER REPORT message, at this point,
The cell-of-origin to switch can receive HANDOVER REPORT message from first community, wherein first community is that UE connects
Connect the cell of failure.
In a preferred embodiment, the cell-of-origin for sending switching receives HANDOVER REPORT message from first community
Before, first community needs to send the HANDOVER REPORT message as follows, and process flow is as follows：
Step A, first community receives the RLF INDICATION message that second community is sent, wherein RLF
Carry CRE relevant informations in INDICATION message, second community is the cell accessed after UE connection failures；
Step B, first community determines the MRO scenes of this detection according to RLF INDICATION message；
It is different according to the MRO scenes of this detection, three kinds of different states can occur, correspond to step C respectively to step
E；
Step C, when the MRO scenes of this detection are to switch too late, first community determines that cell-of-origin is itself, need not send out
Send HANDOVER REPORT message；
Step D, when MRO scenes of this detection are switching too early, first community determines that cell-of-origin is second community, to the
Two cells send HANDOVER REPORT message；
Step E, when the MRO scenes of this detection are that wrong cell switches, first community determines that cell-of-origin is that third is small
Area sends HANDOVER REPORT message to third cell, wherein third cell is to be different from first community and second community
Other cells.
And before step A refers to the MRO scenes that first community determines this detection according to RLF INDICATION message,
Second community receives the RRC that UE is sent and rebuilds after trial or RLF Report before step A, can just trigger corresponding operating, i.e.,
RLF INDICATION message is sent to first community；Disappear alternatively, sending RLFINDICATION to first community from the 4th cell
Breath, the 4th cell are that UE connection failures enter the cell accessed again after idle (idle) state, and the 4th cell receives UE hairs
After the RLF Report sent, RLF INDICATION message is sent to first community.
Specifically, when if second community receives the RRC reconstruction trials that UE is sent, UE is utilized
RRCConnectionReestablishmentRequest message carry CRE relevant informations, later second community from
RRCConnectionReestablishmentRequest message obtains CRE relevant informations, and carries in RLF INDICATION
First community is sent in message.
Similarly, when second community or the 4th cell receive the RLF Report of UE, UE is utilized
UEInformationResponse message carries CRE relevant informations, later second community or the 4th cell from
UEInformationResponse message obtains CRE relevant informations, and carries and be sent to the in RLF INDICATION message
One cell.
In this example, UE carries CRE relevant informations using UEInformationResponse message, sends it to second
Cell or the 4th cell, it is contemplated that between UE and second community or the 4th cell can have different instruction information, different signalings
And the transmission of different data, therefore, how UE transmits CRE relevant informations can be there are many mode, and now two kinds of offer is preferably
Processing method.
Method one
UE is in RRCConnectionReestablishmentComplete or RRCConnectionSetupComplete
The instruction of available RLF Report is carried in message；
After second community or the 4th cell receive the instruction of available RLF Report, sent out to UE
UEInformationRequest message, wherein UEInformationRequest message carries RLF Report requests and refers to
Show；
After UE receives UEInformationRequest message, returned to second community or the 4th cell
UEInformationResponse message, wherein RLF Report are carried in UEInformationResponse message,
CRE relevant informations are carried in RLFReport.
Method two
UE is in RRCConnectionReestablishmentComplete or RRCConnectionSetupComplete
The instruction of available CRE relevant informations is carried in message；
After second community or the 4th cell receive the instruction of available CRE relevant informations, sent to UE
UEInformationRequest message, wherein the request of CRE relevant informations is carried in UEInformationRequest message
Instruction；
UE is received after the request instruction of CRE relevant informations, it is preferable that second community or the 4th cell in the present embodiment
Return to UEInformationResponse message, wherein CRE correlations letter is carried in UEInformationResponse message
Breath.
In above-mentioned preferred embodiment, however, it is determined that MRO self-optimizing schemes be then the when not counting this MRO problem
One cell need not send HANDOVER REPORT message to cell-of-origin.
It is clearer to become apparent from MRO scene detection methods provided in an embodiment of the present invention with illustrating, now with specific implementation
Example is described.
Embodiment one
It is compared for convenience of the MRO scene detection methods provided with the relevant technologies, the application environment and phase of the present embodiment
Pass technology is identical, that is, the UE of the present embodiment is also as shown in Figure 1, the present embodiment carries in the connection of minizone and switching mode
1) the MRO scene detection methods of confession are mainly included the following steps that step 5)：
1) connection failure (HOF or RLF) has occurred in UE in cell 1 (i.e. first community)；
2) UE progress RRC in cell 2 (i.e. second community), which are rebuild, attempts, and
CRE relevant informations are carried in RRCConnectionReestablishmentRequest message；Or report RLF to cell 2
Report carries CRE relevant informations in UEInformationResponse message；Or UE connection failures enter idle states
It accesses cell 4 (i.e. the 4th cell) again afterwards, RLF Report is reported to cell 4, in UEInformationResponse message
Middle carrying CRE relevant informations；
3) cell 2 is after receiving RRC and rebuilding trial or RLF Report or cell 4 is after receiving RLF Report, according to
Connection failure has occurred in UE known to its content in cell 1, then sends RLF INDICATION message to eNB belonging to cell 1,
Carry CRE relevant informations；
4) after eNB belonging to cell 1 receives RLF INDICATION message, can be judged according to its content；Such as it is determined as
Switch too late, then the cell-of-origin for initiating switching is cell 1 oneself, so without hair HANDOVER REPORT message；Such as judgement
To switch too early, then the cell-of-origin for initiating switching is cell 2, is disappeared so to send out HANDOVERREPORT to eNB belonging to cell 2
Primary switching too early has occurred with notifying cell 2 in breath；Such as it is determined as that wrong cell switches, then the cell-of-origin for initiating switching is not
Other cells of cell 1 or cell 2 are same as, so HANDOVERREPORT message is sent out to other affiliated eNB of cell, with logical
Know that a wrong cell switching has occurred in it；CRE relevant informations are carried in HANDOVER REPORT message.
5) receive the affiliated eNB in cell-of-origin of HANDOVER REPORT message according to message content be have occurred it is primary
Switching too early caused by oneself or wrong cell switching, but also need according to the CRE relevant informations carried in message come comprehensive analysis,
It could finally determine MRO self-optimizing schemes, such as：Whether the secondary MRO problems (switching too early or wrong cell switch) are counted
Inside；Or to having used CRE and the MRO problems of CRE not used to count respectively；Then be separately optimized mobility parameters and
CRE offsets, or two sets of mobility parameters are separately optimized.It is not send out HANDOVERREPORT message for switching too late,
But the affiliated eNB in cell-of-origin could finally determine MRO self-optimizing schemes after should also combining CRE relevant information comprehensive analysis.
