Description
Technical field
The present embodiments relate to mobile communication technology field more particularly to a kind of cell switching control method and base stations.
Background technique
With the development of mobile communication technology, long term evolution (the Long Term of universal mobile communications technology
Evolution, LTE) a large amount of user market share already taken up with its superior characteristic.In LTE, the single nothing of enhancing
Line continuous voice call (Enhanced Single Radio Voice Call Continuity, ESRVCC) be one compared with
For important technology.ESRVCC is continuous (Single Radio Voice Call Continuity, SRVCC) to voice to list
Enhancing.Wherein, SRVCC refers to user in communication process from the UMTS Terrestrial radio access network of evolution (Evolved UMTS
Terrestrial Radio Access Network, E-UTRAN) roam into UMTS wireless access network (UMTS Radio
Access Network, UTRAN)/GSM EDGE wireless access network (GSM EDGE Radio Access Network, GERAN)
When, by the switching of user terminal (User Equipment, UE) and the network equipment, keep continuous voice call, i.e. user
It converses unbroken technology.
ESRVCC optimizes the networking of SRVCC.Specifically, ESRVCC passes through setting access conversion and control function (Access
Transfer Control Function, ATCF) ATCF/ access transfer gateway ATGW (Access Transfer Gateway,
ATGW) functional entity in Call-Establish-Success rate (Call Session Control Function, CSCF) node P-CSCF with
Between I-CSCF/S-CSCF, Media Stream is anchored to ATGW by the calling switched for SRVCC may occur, subsequent in this way to send out
When raw SRVCC switching, it is only necessary to update the media information on ATGW, the media information without updating distal end UE makes
Entire SRVCC switching time is shorter.
Specifically, the process of ESRVCC mainly includes preparation stage, IST stage and execution stage.The execution stage mainly wraps
It is synchronous in global system for mobile communications (Global System for Mobile communication, GSM) network to include UE
Access, and pass through base station controller (Base Station Controller, BSC), mobile switching centre (Mobile
Switching Center, MSC) inform enhancing mobile switching centre (Enhanced Mobile Switching Center,
EMSC) UE has been successfully accessed, and EMSC forwards PS to CS switching to be completed to mobile management entity by Sv interface later
(Mobility Management Entity, MME) informs that user switches successfully, then is triggered and deleted under all LTE of UE by MME
Layer carrying.
However, execute ESRVCC switching when may switch failure the case where, i.e., user target GSM cell without
The synchronous access of method, at this point, call drop, UE can not select wireless heterogeneous networks in order to keep VOLTE (Voice Over LTE) call
(Radio Resource Control, RRC) rebuilds back LTE cell, and Xiang Yuan LTE cell, which is sent back, builds request, and source LTE cell is received
It is built after request to time and sends handover cancelling request to MME, while source LTE cell will record the UE and execute ESRVCC handover failure one
It is secondary.
The case where for handover failure, in the prior art, there are source LTE cells for UE and the punishment machine of Target cell
System, penalty mechanism is usually following form: in this communication process, which may initiate to same Target cell again
ESRVCC switching attempt, and source LTE cell allow the UE to this Target cell continuously initiate x switching retry (x be a present count
Value)；After reaching x times, for this UE, the switching of Target cell is retried in view of this in this communication process, and source cell will no longer
Switching request is initiated to this Target cell, prevents the cutting off rate as caused by abnormal cause from rising.
However, above-mentioned penalty mechanism is the punishment of point-to-point form, i.e., just for a particular terminal during current talking
With a specific objective cell.For example, terminal UE a switches in source LTE cell to the ESRVCC of Target cell M when above-mentioned x is 1
Execute failure and return build source LTE cell after, in this call, switching request machine of the terminal UE a one more to Target cell M
Meeting；But under the low access property scene of some burst GSM (for example GSM interference unit is opened in examination), may there are UEb, UEc etc.
Multiple UE may be generated largely to the ESRVCC switching request of the lower Target cell X of access property in a short time, be occupied
Radio resource causes channel to block；And at this time due to be for the first time request, source LTE cell will not be refused, still can look for MME,
EMSC coordinates resource, and unsuccessfully returns in the execution stage and build back source LTE cell, and the source LTE for eventually leading to multiple UE such as UEb, UEc is small
Area side switch penalty is opened, and ESRVCC handover success rate is influenced.
Summary of the invention

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, those of ordinary skill in the art
Every other embodiment obtained without creative efforts, shall fall within the protection scope of the present invention.
Fig. 1 shows a kind of flow diagram of cell switching control method provided in an embodiment of the present invention.
As shown in Figure 1, cell switching control method provided in an embodiment of the present invention, is applied to source cell, the method tool
Body the following steps are included:
Step 101, when receiving the failure switchback request of terminal transmission, determine that the failure switchback requests corresponding target
Cell；The failure switchback request is that the single wireless voice calling continuity ESRVCC switching of terminal execution enhancing executes failure
Request is built in returning afterwards.
Wherein, terminal is any terminal in the source cell coverage area.Terminal is when executing ESRVCC switching, if switching
Failure, can fail switchback request to source cell transmission, i.e., terminal executes returning after ESRVCC switching execution fails and builds request, to return
It builds to source cell.
Source cell, according to failure switchback request, determines failure switchback request after the failure switchback request for receiving terminal
Corresponding Target cell, to determine the current accessibility situation of Target cell.Target cell i.e. failure switchback request is corresponding
Target cell in ESRVCC switching.
Under normal conditions, source cell is LTE cell, and Target cell is GSM cell.
Step 102, the request number of times that the failure switchback for corresponding to the Target cell is requested is determined.
Wherein, failure switchback described in this step request be the source cell coverage area in any terminal send,
Failure switchback corresponding to the Target cell is requested, i.e., identified request number of times is specific corresponding to one in this step
The request number of times of the failure switchback request of Target cell, and the originating end of failure switchback request is one or at least two UE；?
It is many-to-one relationship between terminal and Target cell.
For example, when there are 4 UE, respectively a, b, c and d in the source cell coverage area, wherein a, b, c difference
The failure switchback request corresponding to Target cell e is had sent to source cell, d sends the mistake for corresponding to Target cell f to source cell
Lose switchback request；At this point, the sum of failure switchback request number of times transmitted by a, b, c is the failure switchback corresponding to Target cell e
The request number of times of request, and failure switchback request number of times transmitted by d is asking for the failure switchback request corresponding to Target cell f
Seek number.
Step 103, it when the request number of times reaches the preset threshold of the Target cell, stops forwarding for the mesh
Mark the ESRVCC switching request of cell.
Specifically, when the request number of times reaches and (be greater than or equal to) preset threshold of the Target cell, it may be determined that
The Target cell is currently at the lower situation of accessibility, carries out penalty mechanism to the Target cell at this time, stops turning
Hairpin handovers request to MME to the ESRVCC of the Target cell, stops ESRVCC switching flow.
For example, having currently corresponded to the request number of times of failure switchback request of Target cell e for Target cell e
Through reaching the preset threshold of Target cell e, then source cell is received again by ESRVCC switching of any terminal to Target cell e later
When request, source cell no longer responds the switching request, does not forward this to handover request to MME, to avoid in the low access of Target cell e
Property scene under, occur more times of multiple and different UE in the coverage area of source cell in the short time and execute ESRVCC respectively switching and switch
Failure, influences ESRVCC handover success rate.
Optionally, the preset threshold of the Target cell can be preset.
As the first example, referring to fig. 2, in schematic diagram of a scenario shown in Fig. 2, show including UE, source cell, MME with
And the interaction schematic diagram of the cell switching control method including Target cell；Wherein, mainly include following main flow:
1.UE sends measurement report to source cell.
UE sends measurement report to source cell, carries Target cell title or identifier in measurement report.
2. source cell forwards ESRVCC switching request to MME.
3.MME sends ESRVCC switching request to Target cell.
4.UE switches to Target cell handover failure.
5.UE sends failure switchback request to source cell.
6. penalty mechanism is executed to Target cell when the request number of times reaches the preset threshold of the Target cell,
Stop forwarding the ESRVCC switching request for the Target cell.
Wherein, to Target cell execute penalty mechanism when, source cell no longer forwards this to handover request to MME, to avoid
Under the low access property scene of Target cell, multiple and different UE more times occurred in the coverage area of source cell in the short time execute respectively
ESRVCC switching and handover failure, influence ESRVCC handover success rate.
In the above embodiment of the present invention, requested in the failure switchback corresponding to a Target cell for receiving terminal transmission
When, the request number of times of all failure switchback requests of the Target cell is corresponded to by determining, and reach default in request number of times
When threshold value, starts the penalty mechanism for the Target cell, stops forwarding the ESRVCC switching request for the Target cell,
No longer allow any terminal to execute ESRVCC to the Target cell to switch, realizes the linkage punishment of cell-level, avoid in target
Cell is under low access property scene, and multiple and different UE more times occurred in the coverage area of source cell in the short time execute respectively
The case where ESRVCC switching and handover failure, improve ESRVCC handover success rate.The embodiment of the present invention solves the prior art
The penalty mechanism of middle ESRVCC handover failure be easy to cause and generates a large amount of ESRVCC switching request in a short time, influences
The problem of ESRVCC handover success rate.
Optionally, in the embodiment of the present invention, the determination corresponds to the request that the failure switchback of the Target cell is requested
The step of number, comprising:
It determines in the first preset duration, the request number of times that the failure switchback corresponding to the Target cell is requested.
Wherein it is determined that correspond to the Target cell failure switchback request request number of times when be limited to first it is default when
It is long, to improve the accuracy of the result for the accessibility for determining Target cell, for example, if when the first preset duration is one shorter
Between, ten minutes or 15 minutes etc., if then request number of times is more than preset threshold, it can determine that the accessibility of Target cell is poor；
If not setting the first preset duration, request number of times may be the data in the long period, then whether can access to Target cell
Judgement result will lose referential.
Further, in the embodiment of the present invention, the determination is in the first preset duration, corresponding to the Target cell
The step of request number of times of failure switchback request, comprising:
Starting is directed to the first timer of the Target cell, and the timing of the first timer is described first pre-
If duration；
It determines in the timing of the first timer, the received failure corresponding to the Target cell is returned
Cut the request number of times of request.
Wherein, in source, LTE cell side receives first UE and executes returning after failure for the ESRVCC of Target cell and builds and ask
When asking, starting is directed to the first timer of the Target cell, and first timer is used to limit asking for statistics failure switchback request
The statistics duration of number is sought, to judge the accessibility of Target cell.
Optionally, which is the maintenance of source cell side, and initial stage can be set to 15 minutes.
After first timer starts timing, the request number of times of statistics (determination) failure switchback request.And counted
Failure switchback request be in the coverage area of source cell any terminal send, ask corresponding to the failure switchback of the Target cell
It asks.
Further, in the embodiment of the present invention, the determination is received in the timing of the first timer
Corresponding to the Target cell failure switchback request request number of times the step of, comprising:
Starting is directed to the first counter of the Target cell；
The failure switchback request corresponding to the Target cell is often received, first counter is controlled and adds count value
One；
According to the count value of first counter, the request number of times is determined.
Wherein, when starting first timer, while starting the first counter.First counter is for counting failure switchback
The request number of times of request.For example, receiving the failure switchback corresponding to Target cell every time in the timing of first timer
When request, the count value of the first counter is added one；Failure switchback request can come from different UE, but both correspond to this
Target cell.
For example, Target cell is X cell, the first timer for X cell is timer A, for the first meter of X cell
Counting device is counter B, in timer A starting, often receives an ERSVCC switching execution and unsuccessfully returns the failure time for building source cell
When cutting request, the count value of counter B increases by 1.
In the timing of first timer, according to the count value of the first counter, the request number of times is determined.
Optionally, in the embodiment of the present invention, the determination corresponds to the request that the failure switchback of the Target cell is requested
After the step of number, the method also includes:
When the request number of times is not up to the preset threshold of the Target cell, by the count number of first counter
It is worth zero setting.
That is, according to the count value of the first counter, determining request time in the timing of first timer
When number is not up to the preset threshold of the Target cell, it may be determined that Target cell is not currently in the lower situation of access property, no
Need to be implemented penalty mechanism, then by the count value zero setting of first counter, when to start first timer next time,
First counter can work normally.
Optionally, in the embodiment of the present invention, the preset threshold that the Target cell is reached when the request number of times
After step, the method also includes:
Close the first timer.
That is, if the timing of first timer not yet at the end of (when i.e. first timer has not timed out), if
Request number of times has reached preset threshold, it may be determined that Target cell is currently at the lower situation of accessibility, at this time to described
Target cell carries out penalty mechanism, and closes the first timer.
Optionally, in the embodiment of the present invention, the ESRVCC switching request stopped forwarding for the Target cell
Step, comprising:
Starting is directed to the second timer of the Target cell；
In the timing of the second timer, the switching stopped forwarding for the ESRVCC of the Target cell is asked
It asks.
It, can be true when the request number of times reaches and (be greater than or equal to) preset threshold of the Target cell in this step
The fixed Target cell is currently at the lower situation of accessibility, carries out penalty mechanism, starting to the Target cell at this time
For the second timer of the Target cell, and in the timing of the second timer, stop forwarding for described
The ESRVCC of Target cell handovers request to MME, stops the ESRVCC switching flow in the timing of the second timer
Only, in the timing of the second timer, the multiple and different UE occurred in the coverage area of source cell can be effectively prevented from
The case where repeatedly executing ESRVCC switching and handover failure respectively occurs, to improve ESRVCC handover success rate.
Optionally, in the embodiment of the present invention, after described the step of starting the second timer for being directed to the Target cell,
The method also includes:
When the second timer time-out, starting is directed to the third timer of the Target cell；
In the third timer timing, if receiving the failure switchback request corresponding to the Target cell,
Start the second timer.
Wherein, when the second timer time-out, source cell can normally forward the ESRVCC corresponding to Target cell to cut
Request is changed, and starting is directed to the third timer of the Target cell at this moment, to verify in second timer time-out
Whether (i.e. the timing of third timer) receives the mistake corresponding to the Target cell again in preset time period afterwards
Lose switchback request；If receiving the failure switchback request corresponding to the Target cell again, start the second timing again
Device, and in the timing of the second timer, stop forwarding the switching request of the ESRVCC for the Target cell.
Further, in the embodiment of the present invention, the step of the starting second timer, comprising:
Start the second timer, and this timing length of the second timer is increased by a default value.
Wherein, after being again started up the second timer, show that the failure switchback corresponding to current goal cell is asked
It asks more intensive, under the timing length of a second timer, the lower situation of accessibility can not be alleviated, at this time by institute
This timing length for stating second timer increases by a default value, to optimize the timing length of second timer, improves
ESRVCC handover success rate.
In the above embodiment of the invention, it is asked in the failure switchback corresponding to a Target cell for receiving terminal transmission
When asking, starting is directed to the first timer of Target cell, true by the first counter in the timing of first timer
Surely the request number of times corresponding to all failure switchback requests of the Target cell, and when request number of times reaches preset threshold, it opens
It is dynamic that the penalty mechanism of the Target cell is stopped forwarding in the timing of second timer for the Target cell
ESRVCC switching request, no longer permission any terminal to the Target cell execute ESRVCC switch, realize the connection of cell-level
Dynamic punishment, avoids in the case where Target cell is in low access property scene, occur in the short time in the coverage area of source cell it is multiple not
The case where executing ESRVCC switching and handover failure respectively with UE more times, improves ESRVCC handover success rate.
Below with the second example, cell switching control method provided in an embodiment of the present invention is introduced.
Referring to Fig. 3, in schematic diagram of a scenario shown in Fig. 3, source cell is source cell X, and Target cell is Target cell Y；Knot
Fig. 4 is closed, flow chart shown in Fig. 4 is this exemplary method flow diagram.
Specifically, it is mainly comprised the steps that in method flow diagram shown in Fig. 4
Step 401, it when source cell X receives the failure switchback request of terminal U1, determines corresponding in failure switchback request
Target cell is Target cell Y.
Wherein, when the side source cell X receives the failure switchback request of first terminal U1, determine that failure switchback request is corresponding
Target GSM cell is Target cell Y.
Step 402, starting is directed to the timer A and counter B of Target cell Y.
Wherein, start the timer A that whether can access for judging Target cell Y, which is the maintenance of source cell side,
Initial stage can be set to 15 minutes, while the counter B whether starting can access for judging Target cell.Wherein, in timing
When device A starts, often receive in the X coverage area of source cell any terminal (can be terminal U1, terminal U2 ..., terminal
Any one in Un) send the request of failure switchback when, the technology numerical value of counter B increases by 1.
Step 403, in the timing of timer A, judge whether the count value of counter B reaches Target cell Y
Preset threshold:
If so, thening follow the steps 404；
Otherwise, step 405 is executed, timer A is stopped, after waiting ERSVCC handover execution stage failure next time again
Starting.
Step 404, starting is stopped forwarding and is directed in the timing of timer C for the timer C of Target cell Y
The switching request of the ESRVCC of the Target cell.
Wherein, timer C punishes timer.Punishment timer has not timed out, and the source cell side X is all for mesh to what is received
The ESRVCC switching request of mark cell Y is ignored, and is not forwarded to the side MME.
Step 406, in timer C time-out, starting is directed to the timer D of Target cell Y.
Wherein, timer D verifies timer.It is opened when timer C stops, for verifying in timer C stopping
In preset time period, if be received again by the failure switchback request for Target cell Y.
Step 407, if in the timing of timer D, it is received again by the failure switchback request for Target cell Y, then
It is again started up timer C, starting is directed to the penalty mechanism of Target cell Y.
Wherein, in the timing of timer D, once source cell X is received again by the failure switchback request of Target cell Y,
Then stop timer D, and the timing of adjust automatically timer C, for example timer time is increased to 2 points on the original basis
Clock.
It is again started up timer A and counter B simultaneously.
In the second example of the invention, requested in the failure switchback corresponding to Target cell Y for receiving terminal transmission
When, starting is directed to the timer A of Target cell Y, in the timing of timer A, is determined by counter B and corresponds to mesh
The request number of times of all failure switchback requests of cell Y is marked, and when request number of times reaches preset threshold, is started for the target
The penalty mechanism of cell stops forwarding the ESRVCC switching request for Target cell Y, no in the timing of timer C
Any terminal is allowed to execute ESRVCC switching to the Target cell again, the linkage punishment for realizing cell-level and source cell X are certainly
It is main whether to judge opposite end GSM cell there may be low access character condition, it avoids in the case where Target cell is in low access property scene, it is short
Multiple and different UE more times occurred in the coverage area of source cell in time execute the case where ESRVCC switches simultaneously handover failure respectively,
Reduce a possibility that ESRVCC handover success rate caused by the low access property of burst GSM drops suddenly.
Cell switching control method provided in an embodiment of the present invention is described above, introduces the present invention below in conjunction with attached drawing
The base station that embodiment provides.
Referring to Fig. 5, the embodiment of the invention provides a kind of base station 500, the base station 500 includes:
Receiving module 501 when for receiving the failure switchback request of terminal transmission, determines the failure switchback request pair
The Target cell answered；The failure switchback request is the single wireless voice calling continuity ESRVCC switching that terminal executes enhancing

The request number of times of failure switchback request, and the originating end of failure switchback request is one or at least two UE；Namely terminal and mesh
Marking between cell is many-to-one relationship.
Stopping modular 503 stops forwarding needle when for reaching the preset threshold of the Target cell when the request number of times
To the ESRVCC switching request of the Target cell.
Specifically, when the request number of times reaches and (be greater than or equal to) preset threshold of the Target cell, it may be determined that
The Target cell is currently at the lower situation of accessibility, carries out penalty mechanism to the Target cell at this time, stops mould
Block 503 stops forwarding the ESRVCC for the Target cell and handovers request to MME, stops ESRVCC switching flow.
For example, having currently corresponded to the request number of times of failure switchback request of Target cell e for Target cell e
Through reaching the preset threshold of Target cell e, then source cell is received again by ESRVCC switching of any terminal to Target cell e later
When request, source cell no longer responds the switching request, does not forward this to handover request to MME, to avoid in the low access of Target cell e
