Description
Technical field
The present embodiments relate to penalty methods after wireless communication technology field more particularly to a kind of cell switching refusal.
Background technique
Currently target is being moved to from source LTE cell using the user terminal (User Equipment, UE) of network service
LTE cell, or due to the adjustment of radio services load, activation Operation and Maintenance, equipment fault etc., in order to guarantee to lead to
The communication link of the user and source cell are transferred in new cell by the continuity of letter and the quality of service, system, this
Process is exactly to switch.In LTE system, switching is (based on X2 mouthfuls of switchings or based on S1 between switching can be divided into switching in station, stand
Mouth switching).When the source cell where UE is not belonging to same base station eNodeB with the Target cell to be switched, cut between standing
It changes, switching flow is complicated between standing, and needs to be added the signaling manipulation of X2 and S1 interface.When X2 interface data configuration improves and works
X2 switching will occur in good situation, S1 switching otherwise will occur between base station.In general the priority of X2 switching is high
Switch in S1.Switching between regulation eNodeB in agreement 36.300 will generally be carried out by X2 interface, but when in following condition
Any one switches between then triggering the eNodeB of S1 interface when setting up: (1) not depositing between source eNodeB and target eNodeB
In X2 interface；(2) source eNodeB attempts to switch by X2 interface, but is refused by target eNodeB.Base station is according to different needs
Different types of measurement task is issued to UE using mobile management algorithm, is carried in radio resource control RRC reallocation message
MeasConfig cell is configured to UE sending measuring；After UE receives configuration information, to measurement object implement measure, and with measure
It reports standard to carry out outcome evaluation, sends corresponding measurement report to base station after assessment of the measurement result satisfaction reports standard, than
Such as A2 A3 event.Base station decides whether to execute switching by the measurement report that terminal reports.When judgment condition reaches, hold
Row following steps: switching prepares: target network completes resource reservation；Switching executes: source base station notice UE executes switching, and UE exists
It connects and completes on target BS；Switching is completed: source base station discharges resource, link, deletes user information.Wherein before X2 switching
The condition of mentioning is target BS and source base station is configured with X2.33 link, and link is available.It needs first to lead to after being connected to measurement report
It crosses X2 interface and sends handover request to Target cell (Target cell whether there is access-in resource)；After obtaining Target cell feedback
(Target cell resource preparation at this time is completed) Cai Huixiang terminal sends switching command, and sends to target side and have data packet
The SNStatus Transfer message of the information such as caching, data pack buffer number；After UE after Target cell access, Target cell
It can be to core net transmitting path replacement request, it is therefore an objective to notify core net that the business of terminal is transferred to Target cell, update and use
The node relationships in family face and control plane；After handover success, target eNodeB notifies source eNodeB to discharge radio resource.X2 is cut
It changes priority to switch greater than S1, ensure that handover delay is shorter, user's perception is more preferable.And in S1 switching flow, S1 switching stream
Journey is similar with X2 switching, and only interaction signaling and data forwarding require to carry out by S1 mouthfuls to core net between all stations
Forwarding, time delay ratio X2 switching are bigger.It, can be two eNodeB and mobile controlled entity from the point of view of LTE network structure
S1 interface between (Mobility Management Entity, MME) regards a logic X2 interface as together with MME entity.
It is compared to the process by X2 interface, the process switched by S1 interface has in switching preparation process and switching complete process
Institute is different.The precondition of S1 switching: target BS and source base station do not configure X2 link, or the X2 link of configuration can not
With.If being configured with X2 and S1 link simultaneously, X2 switching is preferentially walked.Process is not across MME and gateway (Serving
GateWay, SGW), it is relatively easy.Even if being related to across MME, main flow difference is little, mainly more in the signaling meeting of core net
A bit.The main distinction that X2 switching switches in handoff preparation phase with S1 mouthfuls is that target LTE cell is directly fed back
Switching prepares to reply or target LTE cell informs MME, then feeds back switching by MME and prepare to reply.
Source LTE cell receives switching and prepares to judge to carry out next step process according to result is replied after replying, if this
When the switching that receives to prepare to reply be resources-type admission rejection, then enter penalty mechanism.If target LTE cell A feeds back (X2
Switching) for/MME feedback (S1 switching) the resources-type refusal of handoff preparation phase to source LTE cell, source LTE cell analyzes failure cause
(failure of resource access fails with non-resource access) be not if feeding back following cause value (has available wireless money in Target cell
Source No radio resources available in target cell, the unavailable Transport of transfer resource
Resource unavailable, user surface treatment inadequate resource Not enough User Plane Processing
Unavailable Radio resources not available of Resources, radio resource, control plane processing overload Control
Processing Overload), then it is judged as that resource access fails, source LTE cell can take time mechanism to punish.Now net is set
It setting generally 30 seconds, i.e. the UeA is in this communication process, once the switching request for reporting Target cell A to occur again, source LTE
Cell does not respond.Once (terminal UeA, which switches in 30 seconds, rebuilds etc., causes source LTE cell context to discharge, terminal
After UeA returns to source eNodeB, LTE cell in source prepares unsuccessfully punishment timer counter resetting at this time, and terminal UeA can be again
It initiates switching to attempt).If returning to other reasons value than that described above, it is judged as that non-resource access fails, source LTE is small
Area will carry out number punishment to Target cell A.If source LTE cell is successfully received the measurement report of the UeA and contains the target
Cell A, then eNodeB will not initiate switching request to Target cell A, while punish that number adds 1.When the punishment of Target cell A
To (now net setting predominantly 60 times) after 60 times, the measurement report that eNodeB receives UeA again contains Target cell A for number accumulation,
Could switching request be initiated to Target cell A again.If there is non-resource access failure situation again in Target cell A, for
This UeA, source LTE cell no longer initiate switching request to the Target cell A retried.Prevent the call drop as caused by abnormal cause
Rate rises.
The prior art carries out the punishment of point-to-point form just for terminal UeA during current talking and Target cell A,
After when source, LTE cell receives the resources-type refusal of the handoff preparation phase about UeA, in this call in certain period of time not
The switching request of Target cell A is directed to MME forwarding UeA again.But under the big traffic scene that happens suddenly, there certainly will be terminal
The UE such as UeB, UeC are directed to the first time switching request of Target cell A, and at this time due to being to request for the first time, source LTE cell will not
Refusal, still can look for target A cell coordination resource, certainly, as a result certainly will still resources-type preparation fail, finally result in and be directed to
The resources-type refusal of the source LTE cell side handoff preparation phase of UeB, UeC is opened, but the switching of first time LTE of UeB, UeC is asked
Seek failure objective reality.Now gateway can still result in the resources-type refusal for the big traffic scene that happens suddenly there are certain loophole
Occur under the big traffic scene that happens suddenly repeatedly, the LTE handoff preparation phase failure of different UE triggerings, to cause a large amount of letter
Enable consumption and the wasting of resources.

Specific embodiment
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention
In attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is
A part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, ordinary skill people
Member's every other embodiment obtained without creative efforts, shall fall within the protection scope of the present invention.
Fig. 1 is penalty method flow chart after the cell switching of the embodiment of the present invention is refused, as shown in Figure 1, the method packet
It includes:
Step S01, the measurement report sent by user terminal is received, the measurement report includes at least Target cell.
In order to guarantee the continuity and service quality of user terminal communication, cell where the user terminal, i.e. source is small
Area, it includes measurement task in RRC reallocation message that corresponding source base station, which can be sent according to itself needs to user terminal,
So that user terminal reports standard according to the measurement in the measurement task in the monitoring process to measurement object, meeting
Under conditions of measurement reports standard, measurement report is sent to source base station.Such as the measurement task that source base station is sent to user terminal
For A2 A3 event, if the A2 indicates that the user terminal measurement correspond to reference signal power RSRP less than in advance to place cell
If power threshold then triggers reporting measurement reports, if the A3 indicates that the user terminal measurement is corresponding to other cells
RSRP compared to place cell RSRP be higher than a preset difference threshold, then trigger reporting measurement reports.
Meet the measurement report of cell switching condition when user terminal is sent according to the measurement task received to source base station
When, including at least in the measurement report has Target cell.
If punishment timer step S02, corresponding with the Target cell is in off state, to the Target cell
Corresponding target BS sends switching request, so that the target BS carries out resource preparation.
The source base station is receiving any user terminal after the measurement report that source cell is sent, and can be reported according to measurement
Content in announcement judges whether the measurement report meets cell switching condition, switches if satisfied, can then start to execute cell
User terminal is switched to Target cell by source cell by cell switch process by journey.
The Target cell is in situations such as such as high traffic scene at this time in order to prevent, makes handoff procedure at one section
It cannot achieve in time, source base station can set one and the unique corresponding punishment timer of the Target cell, when source base station is sentenced
The fixed Target cell may turn on punishment timer when being high traffic scene, and start timing.
After the measurement report that the source base station receives, punishment timer corresponding with the Target cell can be first detected
State.If the punishment timer is open state, source base station, which can directly be ignored, meets cell switching in the measurement report
Condition does not execute cell switch process；And if the punishment timer is in off state, source base station can be to the Target cell
Corresponding target BS sends switching request.For example, if the corresponding punishment timer of the Target cell C1 is PT1, source base
Stand S0, and the Target cell obtained in receiving the measurement report sent by user terminal UeA is C1, then source base station can be checked
The state of PT1 decides whether to send switching request to the corresponding target BS S1 of C1.
If the Target cell corresponding with the source cell is the same base station, i.e. source base station and target BS is same
One base station, subsequent cell switch process are switching in station；Otherwise, if source base station and target BS are not same base station, after
Continuous cell switch process is to switch between standing.In order to express easily, in the following embodiments still with source base station and target base
Station is illustrated for respectively indicating source cell and the corresponding base station of Target cell.
When target BS is after receiving switching request, resource preparation process will do it, it is specific to need in Target cell
The user terminal to come in network for request switching prepares corresponding resource.
Step S03, it receives and is replied message by the switching that the target BS is sent.
Target BS during carrying out resource preparation can according to itself the case where come decide whether allow user terminal
Switching request, then to the source base station send switching reply message.If agree to switching, it is described switching reply message for
Otherwise admission message is refuse information, and can include specific Reason For Denial in the refuse information.The Reason For Denial
Can be divided into it is resources-type and two kinds of non-resource class, so that the refuse information can also be divided into resources-type refuse information and non-money
Source class refuse information.The resources-type Reason For Denial indicates that the resource in current goal cell is unable to satisfy switching request, example
It such as, include No radio resources available in target cell, Transport in refuse information
resource unavailable、Not enough User Plane Processing Resources、Radio
The information such as resources not available, Control Processing Overload.
Step S04, if it is determined that the switching replies message as resources-type refuse information, and it is opposite with the Target cell
The refusal timer answered is open state, then increases the value of refusal counter corresponding with the Target cell.
If source base station after replying message and parsing to the switching received, determines that the switching replies message as money
Source class refuse information.It can detect whether refusal timer corresponding with the Target cell is open state, if the refusal is fixed
When device be open state, then can be determined that refusal counter corresponding with the Target cell is also at open state and
It counts, the value of the refusal counter can be added 1.
Further, the method also includes:
If it is determined that the switching replies message as resources-type refuse information, and refusal corresponding with the Target cell
Timer is in off state, then opens the refusal timer and start timing.
If detection obtains and Target cell after source base station receives the resources-type refuse information sent by target BS
Corresponding refusal timer is in off state, then opens the refusal timer and start timing, is both to open refusal counter to open
Begin to count.
Step S05, if it is determined that it is described refusal counter value be more than preset refusal count threshold, then open with it is described
The corresponding punishment timer of Target cell, closes the refusal timer, and resets the refusal counter.
Source base station can monitor the value of the refusal counter in real time, and after each increase, with preset refusal
Count threshold, such as 5, it is compared.If the value for refusing counter at this time has been more than the refusal count threshold, and due at this time
The refusal timer is still open state, i.e., the time of the current refusal timer is not up to preset refusal time threshold
Value such as 15 minutes, then can be determined that the case where Target cell be in such as high traffic scene, need unlatching with it is described
The corresponding punishment timer of Target cell.The refusal timer is simultaneously closed off, and resets the value of the refusal counter.
So far, within the period that the punishment timer is opened, any user terminal that the source base station receives exists
Source cell, which is sent, meets the measurement report of cell switching condition, if the measurement report Target cell that includes and the unlatching are punished
It penalizes timer corresponding, does not then initiate cell switch process.
The embodiment of the present invention is by being arranged corresponding with Target cell punishment timer in source cell, and described in the judgement
When Target cell is high traffic scene, punishment timer is opened, and ignore institute within the period that the punishment timer is opened
There is corresponding measurement report not send switching request to Target cell, so that the cell handover success rate of LTE system is improved,
Save a large amount of signaling consumption, the service efficiency of the resource of raising.
Based on the above embodiment, further, the method also includes
Refuse timer described in real-time monitoring；
If the time of the refusal timer has met or exceeded preset refusal time threshold, the refusal is closed
Timer simultaneously resets refusal counter corresponding with the refusal timer.
After opening the refusal timer and refusal counter, source base station can refusal timer described in real-time monitoring with
Refuse counter.As described above, if the refusal is fixed when the value of the refusal counter is more than the refusal count threshold
When device time not up to or be more than the refusal time threshold when, source base station can open corresponding punishment timer, close simultaneously
The refusal timer is closed, and resets refusal counter.And if the refusal timer is more than refusal in the refusal counter
The refusal time threshold is first reached before count threshold, has then determined that the feelings of high traffic scene are not present in corresponding Target cell
Condition, and the refusal timer is closed, reset the refusal counter.
The embodiment of the present invention is by being arranged corresponding with Target cell punishment timer in source cell, and by described
Refusal timer and refuse the monitoring of counter when determining the Target cell for high traffic scene, to open punishment timer,
And ignore all corresponding measurement reports within the period that the punishment timer is opened not ask to Target cell transmission switching
It asks, to improve the cell handover success rate of LTE system, saves a large amount of signaling consumption, the use effect of the resource of raising
Rate.
Further, the method also includes:
Timer is punished described in real-time monitoring；
If the time of the punishment timer meets or exceeds preset Penalty time threshold value, it is fixed to close the punishment
When device.
When determining the Target cell for high trafficwise situation, source base station will be opened corresponding with the Target cell
Punishment timer.
Source base station takes real-time monitoring to the punishment timer of unlatching, by it is described punishment timer time with it is preset
Penalty time threshold value, such as 10 minutes, it is compared, when the time of the punishment timer meeting or exceeding the punishment
Between threshold value when, source base station can close the punishment timer, i.e. Penalty time terminates.At this point, the source base station receive with
When the corresponding measurement report of the Target cell, it can be started to execute cell switch process, Xiang Suoshu mesh according to the measurement report
It marks cell and sends switching request.
The embodiment of the present invention is by being arranged corresponding with Target cell punishment timer in source cell, and described in the judgement
When Target cell is high traffic scene, punishment timer is opened, and ignore institute within the period that the punishment timer is opened
There is corresponding measurement report not send switching request to Target cell, while monitoring the punishment timer, and in punishment timing
The time of device closes the punishment timer when reaching Penalty time threshold value, so that the cell for improving LTE system switches successfully
Rate saves a large amount of signaling consumption, the service efficiency of the resource of raising.
Based on the above embodiment, further, if the time of the punishment timer meets or exceeds preset punish
Time threshold is penalized, then closes the punishment timer, specifically:
If the time of the punishment timer meets or exceeds preset Penalty time threshold value, punished described in closing
Timer is penalized, and opens verification timer corresponding with the Target cell；Correspondingly, the method also includes:
If it is determined that the switching replies message as resources-type refuse information, and it is corresponding with the Target cell verify it is fixed
When device be open state, then close the verification timer, while opening punishment timer corresponding with the Target cell,
Increase the Penalty time threshold value simultaneously.
If the case where Target cell is in high traffic scene for a long time, even across a Penalty time threshold value,
The Target cell, which is still not present, meets the resource of switching condition to receive user terminal.In order to further save letter
Consumption is enabled, the Penalty time threshold value can be met or exceeded in the time of the punishment timer, and close the punishment timing
Verification timer corresponding with the Target cell is opened while device.
At this point, due to the punishment timer of closing, so when source base station receives the measurement report including the Target cell
When announcement, it can start to execute cell switch process, Xiang Suoshu target BS sends switching request, then can receive by target base
The corresponding switching sent of standing replies message.
If before the time for verifying timer reaches preset verification time threshold, such as 1 minute, do not receive source
In the resources-type refuse information of Target cell, then determine that the Target cell has been no longer on high traffic scene, and verifying timing
The time of device closes the verification timer when reaching the verification time threshold.
If receiving and before the time of the verification timer reaches preset verification time threshold from Target cell
Resources-type refuse information, i.e., when source base station determines that the switching that receives replies message as resources-type refuse information, if monitoring
Verification timer corresponding with the Target cell is open state, then closes the verification timer, while directly opening and corresponding to
Punishment timer.At this point, source base station can also update verification time threshold, that is, increase the verification time threshold, such as increase
2 minutes, by original 10 minutes, become 12 minutes, to increase the opening time of this punishment timer.
The embodiment of the present invention is by being arranged corresponding with Target cell punishment timer in source cell, and described in the judgement
When Target cell is high traffic scene, punishment timer is opened, and ignore institute within the period that the punishment timer is opened
There is corresponding measurement report not send switching request to Target cell, when punishing that timer reaches Penalty time threshold value, opens
Timer is verified, and determines that the Target cell is still in high traffic scene, then punishment timer is directly opened, to mention
The high cell handover success rate of LTE system, saves a large amount of signaling consumption, the service efficiency of the resource of raising.
Based on the above embodiment, further, the method also includes:
If it is determined that the switching replies message as admission message；
If the refusal timer is open state, the refusal timer is closed, and resets the refusal and counts
Device；
If the verification timer is open state, the verification timer is closed, and reset the Penalty time threshold
Value.
By the parsing replied message to the switching sent by target BS that source base station receives, if it is determined that described cut
It changes when replying message as admission message, i.e., the described Target cell has had been prepared for enough resources to receive corresponding user whole
End.Source base station can close the associated timer still opened in above-described embodiment, wherein if the refusal timer and refusal
Counter is open state, then closes the refusal timer and refusal counter, and resets the value of the refusal counter；
If the verification timer is open state, the verification timer is closed, and it is default for resetting the Penalty time threshold value
Initial value.Source base station will continue to execute the subsequent step of cell switch process simultaneously, not illustrate herein.
The embodiment of the present invention is by being arranged corresponding with Target cell punishment timer in source cell, and described in the judgement
When whether Target cell is high traffic scene, if having received admission message, the corresponding timer opened at this time and meter are closed
Number devices, and if determine the Target cell finally for high traffic scene, open punishment timer, and in punishment timing
Ignore all corresponding measurement reports in the period that device is opened and do not send switching request to Target cell, to improve LTE
The cell handover success rate of system saves a large amount of signaling consumption, the service efficiency of the resource of raising.
Based on the above embodiment, further, if the punishment timer corresponding with the Target cell is to close shape
State then sends switching request to the corresponding target BS of the Target cell, so that the target BS carries out resource preparation,
Specifically:
If punishment timer corresponding with the Target cell is in off state, and terminal penalty timer and terminal are punished
It penalizes counter to be in off state, then switching request is sent to the corresponding target BS of the Target cell, so that the target base
It stands and carries out resource preparation；Wherein, the terminal penalty timer and terminal penalty counter with the user terminal and described
Target cell uniquely corresponds to.
The source base station can also be set and each user other than punishment timer corresponding with the Target cell
Terminal and the corresponding terminal penalty timer of Target cell and terminal penalty counter.
Wherein, the terminal penalty timer be the source base station receive resource refuse class message it is post-opening, and
And before the terminal penalty timer reaches default terminal penalty time threshold, such as 30 seconds, if receiving whole by same user
The measurement report comprising same Target cell issued is held, then ignores the measurement report and meets cell switching condition, not to the mesh
The target BS for marking cell sends switching request.For example, the corresponding punishment timer of Target cell C1 is set as PT1, and and user
The corresponding terminal penalty timer of terminal UeA and Target cell C1 is OT1, if the PT1 is opened, any user terminal
The Target cell for including in the measurement report that UeA, UeB or UeC are issued then ignores the measurement report and meets cell if C1
Switching condition does not execute corresponding cell switch process；And if open be OT1, source base station can only be ignored to be issued by UeA
The measurement report comprising C1 still can be to the corresponding target of C1 and for the measurement report comprising C1 that UeB and UeC are issued
Base station S1 sends switching request.
Further, the method also includes:
If it is determined that the switching replies message as non-resource class refuse information, then the terminal penalty counter is opened.
Unlocking condition for terminal penalty counter is to determine that the switching received replies message to refuse for non-resource class
Exhausted message.
If the terminal penalty counter OC1 is corresponding with UeA and C1, when OC1 is opened, if receiving UeA sending
Measurement report comprising C1, then ignore, and the terminal penalty counter is added 1, until the terminal penalty counter reaches
When preset terminal penalty count threshold, such as 60 times, then close the terminal penalty counter.With the terminal penalty timing
Device is identical, and the measurement report that the terminal penalty timer can not similarly issue other user terminals is punished.
When source base station receives measurement report, corresponding punishment timer, terminal penalty timer and terminal are punished
Penalizing the judgement sequencing of counter can be set according to the actual needs, not limited specifically herein.For example,
It can first monitor whether corresponding punishment timer is opened, whether judge the terminal penalty timer again if being not turned on
It opens；Or can also first monitor whether corresponding terminal penalty timer is opened, judge again if being in off state corresponding
Whether punishment timer is opened.It can certainly be set in and directly close the terminal penalty timing when punishment timer is opened
Device and/or terminal penalty counter.
The embodiment of the present invention is by being arranged corresponding with Target cell punishment timer in source cell, and described in the judgement
When Target cell is high traffic scene, punishment timer is opened, and ignore institute within the period that the punishment timer is opened
There is corresponding measurement report not send switching request to Target cell, while being arranged corresponding with user terminal and Target cell
Terminal penalty timer and terminal penalty counter, to punish the measurement comprising same Target cell that same terminal issues
Report saves a large amount of signaling consumption, the use of the resource of raising to improve the cell handover success rate of LTE system
Efficiency.
