To make the objectives, technical solutions, and advantages of the present invention clearer, below in conjunction with attached drawing to the present invention make into
It is described in detail to one step, it is clear that the described embodiments are only some of the embodiments of the present invention, rather than whole implementation
Example.Based on the embodiments of the present invention, obtained by those of ordinary skill in the art without making creative efforts
Every other embodiment, shall fall within the protection scope of the present invention.
Firstly, the part term in the application is explained.
1) mobile management entity (Mobile Managenment Entity, MME), can be used to implement the positioning to UE
And the paging etc. to UE.In practical applications, MME can be the network element in core net.
2) base station can refer to evolved base station (evolved Node B, eNB), eNB can respectively with terminal and MME
Between carry out information transmitting, and the interface between eNB and MME can be S1 interface.ENB can be direct-connected with MEE, or can also be with
MME is linked by a centralized agents node (such as eNB gateway).Alternatively, eNB can also be communicated with other eNB.In reality
In the application of border, eNB can according to the paging request message that MME is sent in eNB coverage area (in one or more cells)
Terminal is initiated to page.
3) eMTC terminal can access network by eNB, can be the UE in cell edge.
The network architecture applied by the application is introduced with reference to the accompanying drawing.
As shown in Figure 1, it is the system architecture of LTE.Within the system, paging request can be initiated by the MME in core net
Message, paging request message can arrive first at base station (eNB) by S1 interface, usually there is multiple cells under eNB, connection
Data transmit-receive of eating dishes without rice or wine is carried out under state between terminal and cell, the distinctive configuration of terminal is carried in the paging request message, such as eventually
The device identification at end and relevant paging message, such as paging cell.ENB is according to paging request message in coverage area
The terminal is paged, and is communicatively coupled to MME feedback paging as a result, can lead to X2 interface between base station and base station.
As shown in Fig. 2, the embodiment of the present invention provides a kind of terminal speed-measuring method, this method can be applied to shown in FIG. 1
In the network architecture.This method may comprise steps of:
EMTC is reported mobile management entity in core net in the context release message of the last time release by S11:eNB
(Mobility Management Entity, MME) receives the context release message.
Wherein, eNB can be the base station that eMTC terminal is accessed before the last release.
The last release of eMTC terminal can refer to radio resource control (Radio Resource
Control, RRC) RCC Connection Release, eMTC terminal enters idle state by connection status.
It may include the mark of eMTC terminal in the context release message of eMTC terminal, eMTC is locating in release goes through
The cell parameter of history cell and the coverage enhancement grade of eMTC terminal etc..
In practical applications, the machine type communication down control channel (MTC of coverage enhancement grade and eMTC terminal
Physical Downlink Control Channel, MPDCCH) number of repetition correlation.MPDCCH number of repetition can be
EMTC terminal the last time accesses the number of repetition (also referred to as history MPDCCH number of repetition) or eMTC terminal used when network
The number of repetition used for the last time before entering Idle state from connected state.For example, MPDCCH number of repetition can be 4 times, 8 times or
Other numerical value etc..Usually, the coverage enhancement bigger grade of eMTC terminal, then the MPDCCH number of repetition of eMTC terminal is also
It is bigger.
ENB, can be in the context for locally saving UE, and by eMTC terminal when the last time discharging UE (such as eMTC terminal)
Context release message in relevant parameter be sent to MME so that MME is when needing to page eMTC terminal according to upper
Hereafter release message generates paging request message.
S12:MME is generated and the paging request message for being directed to eMTC is occurred to eNB, which carries paging
Auxiliary parameter, the cell parameter of the paging auxiliary parameter historical cell that include eMTC terminal corresponding in the last time release and
Send out the paging interval time of paging when the release of distance the last time again to eNB, eNB receives paging request message.
In the embodiment of the present invention, after context release message is reported to core net, core net saves context and releases eNB
Relevant parameter in message is put, when paging the eMTC terminal next time, based on context core net can generate paging by release message
The paging auxiliary parameter of request message, for example, paging auxiliary parameter may include the eMTC terminal the last time release when institute it is right
The cell parameter for the historical cell answered and apart from the last time release when to eNB again initiate paging paging interval when etc. ginseng
Number.
Certainly, paging auxiliary parameter can also include other parameters, such as MPDCCH number of repetition.In practical applications,
For eMTC terminal after being released, the MPDCCH number of repetition of eMTC terminal can be reported to core net by eNB, be saved by core net
The MPDCCH number of repetition that eMTC terminal uses, so that when paging the user equipment next time, core net is by the eMTC of preservation
The corresponding MPDCCH number of repetition of terminal is sent to the base station for needing to be paged to user equipment, so as to need to eMTC terminal
The MPDCCH number of repetition that the base station paged is notified using core net is paged.
S13:eNB pages eMTC terminal according to paging request message, determines the Target cell of eMTC terminal, and root
The spacing distance between historical cell and Target cell is determined according to paging auxiliary parameter, and when according to spacing distance and paging interval
Between determine eMTC terminal movement speed.
In S13, eNB can initiate to page according to paging request message to eMTC terminal, determine corresponding to eMTC terminal
Target cell.The Target cell can be cell locating for the eMTC terminal determined according to paging result, such as Target cell
It can be cell locating for eMTC terminal when paging successfully.In practical applications, which may be identical as historical cell
Or it can also be different.
After determining Target cell, eNB can be determined between historical cell and Target cell according to paging auxiliary parameter
Spacing distance, and then be the movement speed that can determine eMTC terminal according to the spacing distance and paging interval time, realization is being sought
It tests the speed during exhaling to eMTC terminal.
In the embodiment of the present invention, eNB determines the interval distance between historical cell and Target cell according to paging auxiliary parameter
From can realize in the following ways.
Mode one: eNB determines the station spacing between historical cell and Target cell according to the location parameter in cell parameter.
Wherein, the location parameter in cell parameter can be according to the cell deployment situation determination under eNB, can be with table
The location of cell is levied, such as the position can be the center of cell.Therefore, in which, determining station spacing can
To be the distance between center and the center of Target cell of historical cell.
That is, the mobile distance of eMTC terminal is the station spacing in the paging interval time, then, in S13, eNB
The ratio between station spacing and paging interval time can be calculated, which is the movement speed of eMTC terminal.
Mode two: if paging auxiliary parameter further includes that eMTC terminal corresponds to machine type communication down control channel MPDCCH weight
Again it counts, then:
Firstly, eNB can according to location fingerprint in MPDCCH number of repetition, the position of historical cell and historical cell with
Bitmap relationship between MPDCCH number of repetition determines eMTC terminal historical position locating in historical cell.
Wherein, the position of historical cell can be according to the location parameter determination of cell parameter in paging auxiliary parameter.
Bitmap relationship in historical cell between location fingerprint and MPDCCH number of repetition can be to be preset in advance, therefore can determine
EMTC terminal is in MPDCCH number of repetition, the location of in Target cell.That is, eNB can be small according to history
The MPDCCH number of repetition in area and history determines specific location of the eMTC terminal in historical cell, i.e. historical position.
Then, eNB is according to history MPDCCH number of repetition (the MPDCCH number of repetition carried in paging auxiliary parameter)
Determine the current MPDCCH number of repetition when success of eMTC paging terminal.
Current MPDCCH number of repetition, which can refer to, to be carried in paging request message that eNB is sent according to MME
Paging of the MPDCCH number of repetition to eMTC terminal determines eMTC paging terminal success when institute number of repetition.For example, if MME refers to
The history MPDCCH number of repetition shown is 8 times, if eNB is paged successfully in the 6th repetition, current MPDCCH number of repetition
As the 6th time.
In turn, eNB determines the specific location in Target cell according to Target cell and current MPDCCH number of repetition.
At this point, eNB can be according in current MPDCCH number of repetition and Target cell between location fingerprint and MPDCCH number of repetition
Bitmap relationship determines the corresponding location fingerprint of current MPDCCH number of repetition, then the position is eMTC terminal in Target cell
In locating specific location (i.e. target position).
In practical applications, current MPDCCH number of repetition is also possible to be recorded in paging auxiliary parameter.For example, core
Net can also carry relevant calling optimization parameter when providing coverage strength grade, be that UE selection is suitable to assist eNB
MPDCCH number of repetition improves the success rate of paging.The calling optimization parameter may include paging number of attempt, current paging meter
Number, paging domain etc..
Finally, eNB determines spacing distance by calculating the distance between historical position and target position.For example, by two
Relative distance between position is as spacing distance.
After determining spacing distance by above two mode, eNB can be between counting period distance and paging interval total time
Ratio, which is the movement speed of eMTC terminal.
It should be noted that in mode two, due to by conjunction with current MPDCCH number of repetition and bitmap relationship come really
Determine specific location of the eMTC terminal in historical cell and Target cell, help to improve the accuracy to eMTC terminal positioning,
To improve the precision to test the speed to eMTC terminal.
In practical applications, eNB is after paging eMTC terminal according to paging request message, however, it is determined that eNB is pressed
According to MPDCCH number of repetition to the paging failure of eMTC terminal, then eNB can be updated place to MPDCCH number of repetition parameter
Reason.Usually, eNB is the number of repetition for being stepped up paging, before updated MPDCCH number of repetition is greater than update
MPDCCH number of repetition.
For example, eNB for the first time from the paging auxiliary parameter that core net receives MPDCCH number of repetition be 8, eNB just according to
It is paged for 8 times.If paging failure, second of paging request message is received from core net, then eNB can repeat MPDCCH
Count parameter is updated, such as eNB can be with reference to the raw value of the MPDCCH number of repetition in paging auxiliary parameter, such as 8
It is secondary, then MPDCCH number of repetition can be increased to 16 times.
In turn, eNB is using updated MPDCCH number of repetition as the corresponding MPDCCH number of repetition of eMTC terminal, and presses
Repeated paging is carried out to eMTC terminal according to updated MPDCCH number of repetition, such as the cell in eNB coverage area carries out
Paging.
In the embodiment of the present invention, eMTC terminal is paged in the paging request message that eNB is issued according to MEE same
When, the paging time interval for initiating paging again can also be recorded.In record, it can use but be not limited only to following
Mode carries out:
Mode 1:eNB initiates to seek again according to the paging time interval record carried in paging auxiliary parameter to eMTC terminal
The paging time interval exhaled is recorded.
That is, in the paging request message of transmission, carrying is sought if core net when paging eMTC terminal again
Exhaling includes the time interval paged again to eMTC terminal in assistance messages, then between the paging time that eNB can be sent based on MME
The paging time interval of paging is initiated again every record.
For example, core net directly paging auxiliary parameter in carry page again transmission time interval be T2-T1, that is, work as
Preceding calling time subtracts the last traffic release moment, then eNB also may directly learn that the paging time interval for paging transmission again
T2-T1。
The last traffic release time of the eMTC terminal carried in the paging request message that mode 2:eNB is sent according to MME
Record the paging time interval that paging is initiated eMTC terminal again.
That is, if core net again page eMTC terminal when, by the last traffic release time of eMTC terminal
It carries and is sent to eNB in paging auxiliary parameter, then the last traffic release time statistic record that eNB can be sent based on core net
The paging time interval of paging is initiated again.For example, can will be between last traffic release time and the current time for initiating paging
Time difference, as record initiate again paging paging time interval.
For example, if historical cell is reported to core net by eNB, and core net in paging next time by release time last time T1
It is placed in paging auxiliary parameter and informs target eNB.So, it is assumed that eNB the T2 moment receive the paging request message of the user and
It pages successfully, then eNB can learn the time interval T2-T1 for paging transmission again.
In practical applications, when the statistics at paging time interval is also based on the previous release business of eNB oneself preservation
Time.So, the release time record pair when eNB can also be according to the last release of the eMTC terminal of itself storage
EMTC terminal initiates the paging time interval of paging again.
Further, release time when eNB can be by the last release of the eMTC terminal of storage is sent to by interface
Other eNB, release time record when being discharged so as to other eNB according to the last time of eMTC terminal send out eMTC terminal again
Play the paging time interval of paging.So, in practical applications, historical cell information and previous industry that eNB can stop UE
The information such as business release time are sent to other eNB by interface, so that other eNB can be according between cell deployment between different eNB
Gauge tests the speed from the paging interval time for eMTC terminal.
In the embodiment of the present invention, if release time when eNB is discharged according to the last time of the eMTC terminal itself stored
Having recorded the paging time interval for initiating eMTC terminal paging again, then eNB also actively can initiate to page to eMTC terminal, into
And it tests the speed to eMTC terminal.
When paging is initiated in active, the free context for the eMTC terminal that eNB can be saved according to itself initiates to seek again
It exhales, and determines the interval between historical cell position locating when the eMTC terminal position being presently in and release when paging successfully
Distance, when which may include the release that the historical cell information that eMTC terminal stops and the last business discharge
Between.In turn, eNB can according to the determining position being presently in and it is the last discharge when locating historical cell between
Gauge from, and according to eMTC terminal the last time business of storage release release time record eMTC terminal is initiated again
Paging time interval, and calculate the movement speed of eMTC terminal.
Wherein, the historical cell information that eMTC terminal stops may include small where when the previous business of eMTC terminal discharges
The cell information in area, such as subdistrict position or cell ID etc..It is of course also possible to small including all history that history stopped
Area, alternatively, being also possible in preset time the information of the cell (in such as one week), the embodiment of the present invention does not limit this specifically
System.
In an alternative embodiment of the invention, if eNB paging failure in this base station range, eNB can ask paging
Message is asked to be sent to other eNB, such as neighbouring eNB, to initiate to page by other eNB, and according to the paging of other eNB
Response is to test the speed to eMTC terminal.Specifically, paging request message can be sent to other eNB by interface by eNB,
And trigger other eNB and eMTC terminal paged, in turn, eNB can receive the page response of other eNB with according to paging at
The spacing distance when position that eMTC terminal is presently in when function and release between locating historical cell position and nearest one
The paging interval time between the release time of secondary business release and the time paged again tests the speed to eMTC terminal.
For example, eNB is after paging eMTC terminal according to paging request message, however, it is determined that in the small of eNB covering
EMTC terminal is not paged within the scope of area, then shows that eMTC terminal may have moved out in the coverage area of eNB.At this point, eNB can
Paging request message is sent to other eNB, such as is sent to other eNB with eNB, triggers other eNB in its coverage area
It is interior that eMTC terminal is paged, and tested the speed according to the page response that other eNB are fed back to eMTC terminal.
It therefore,, can by triggering paging of its other eNB initiation to eMTC terminal when eNB does not page eMTC terminal
To improve the success rate of paging eMTC terminal, and then realizes and test the speed to eMTC terminal.
Further, if determining that other eNB lose the paging of eMTC terminal after eNB receives the page response of other eNB
It loses, then eNB can determine that eMTC terminal is in except the cell range of eNB and other eNB covering.At this point, eNB can determine root
The historical cell position of historical cell is determined according to the cell parameter of historical cell, and according to the cell of historical cell position and covering
Paging interval between the release time of spacing distance and the last business release between range and the time paged again
Time, to estimate the movement speed of eMTC terminal.For example, eNB can determine historical cell according to the cell parameter of historical cell
Historical cell position, and determine historical cell position and covering cell range marginal position between maximum distance, into
And the movement speed of eMTC terminal is calculated according to maximum distance and paging interval time.
It certainly, in practical applications, can also be direct after free context is sent to other eNB by interface by eNB
It initiates to page and test the speed to eMTC terminal by triggering other eNB.For example, when other eNB are paged successfully, other eNB
Seeking between the release time that can be discharged according to cell deployment spacing distance and the last business and the time paged again
Interval time is exhaled to test the speed eMTC terminal.
Alternatively, if other eNB paging is unsuccessful, show eMTC terminal be in cell range that eNB and other eNB are covered it
Outside.At this point, other eNB can determine the historical cell position for determining historical cell according to the cell parameter of historical cell, and root
According to spacing distance and the release of the last business between historical cell position and the cell range of covering release time with again
The paging interval time between the time of secondary paging, estimate the movement speed of the eMTC.
It therefore, can be according to the marginal position of the coverage area of eNB to eMTC end in the case where eNB pages unsuccessful situation
The band of position after end is mobile is speculated, to estimate eMTC terminal in conjunction with the band of position of paging interval time and supposition
Movement speed, realization test the speed to eMTC terminal.
Illustrate the concrete application of this method below by several scenes.
Scene 1:eNB initiates to page when paging according to historical cell information and again successful cell to the progress of eMTC terminal
It tests the speed.
ENB discharges the business of eMTC terminal at the T1 moment, and by cell (Cell1) where current UE as on historical cell
Registration core net.It is taken on S1 interface with paging request message in subsequent core net using the historical cell as paging auxiliary parameter
It include Cell1 in band, such as paging auxiliary parameter " Recommended Cells for Paging ", eNB receives paging request
After message, the paging to target terminal (i.e. e-MTC terminal) is initiated.
If eNB successful page in Target cell Cell2 is according to historical cell and Target cell to the eMTC terminal
No is same cell, can be divided into following situations:
Situation one: if Cell1 and Cell2 is same cell, shows historical cell and Target cell is same cell, then
Mean the eMTC terminal Hypomobility, such as its movement speed may be 0.
Situation two: it if Cell1 and Cell2 is different community, is tested the speed accordingly according to the determination of base station belonging to each cell
Processing.
If i) Cell1 and Cell2 is the different community under eNB, according between cell deployment spacing distance between eNB and paging
It can test the speed every the time for eMTC terminal.
At this point, eNB can learn distance between the two according to the deployment scenario of Cell2 and Cell1, then it can be according to small
Area's deployment spacing distance and paging interval time can test the speed for eMTC terminal, such as the two station spacing (S) and interval time
(T2-T1) ratio between then obtains UE and was discharged into the movement speed paged in this period again from last time.
Ii) if Cell1 and Cell2 is to show to page successful Target cell again and go through across the different community under eNB
History cell is not at the same eNB.At this point it is possible to be according to cell deployment spacing distance between different eNB and paging interval time
EMTC terminal tests the speed, calculation with i) in it is similar, details are not described herein again.
Scene 2: in paging interval twice, if the tracking area (TA Tracking Area) of core net does not occur for UE
Newly, then core net all will page user using the same S-TMSI when paging twice, i.e., in paging, eMTC is whole
Corresponding S-TMSI is held not change.
Under the scene, eNB can record the time T1 that UE is discharged in previous business, until next time, moment T2 was initiated in paging,
ENB will find the previous business release time of the eMTC terminal in historical record by same No. S-TMSI, thus eNB can
To learn the time interval T2-T1 for paging transmission twice.
For the ii in scene 1) across eNB scene, then eNB can be by historical cell information (optional geography that the UE is stopped
Location information) and the information such as release time last time other eNB are sent to by interface, so that the target eNB of UE is receiving core
It can be surveyed when net paging message according to cell deployment spacing distance between different eNB and paging interval time for eMTC terminal
Speed.
Scene 3: statistics MPDCCH number of repetition increases measurement accuracy;
If eNB discharges the business of the eMTC terminal at the T1 moment, and by cell Cell1 where current UE and currently
The MPDCCH number of repetition of scheduling is reported to core net as paging auxiliary information.In subsequent core net by the paging auxiliary information
Include Cell1 in the paging auxiliary parameter carried on S1 interface with paging request message, notifies eNB, while carrying MPDCCH
Number of repetition initiates the paging to target terminal convenient for eNB.
If eNB is still in Cell1, and using the MPDCCH number of repetition successful page of history to the eMTC terminal, then
Mean the eMTC terminal Hypomobility;And if eNB is still in Cell1, but on the basis of the MPDCCH number of repetition of history
Number of repetition ability successful page is gradually increased to the eMTC terminal, then means that the eMTC terminal moves the margin location to cell
It sets, and the promotion of MPDCCH number of repetition is bigger, then means the UE closer to edge.If network can be successfully established decoding in advance
The bitmap relationship of the fingerprint (Fingerprint) of position, then can orient and page again in MPDCCH number of repetition and cell
When UE, the specific location that UE is moved to, to further increase measurement accuracy.
After the release of scene 4:eMTC terminal, other than core net is initiated to page again and be tested the speed to eMTC terminal, eNB
Also paging can be actively initiated to test the speed to eMTC terminal.
After the release of eMTC terminal, eNB also can actively be initiated according to the free context of preservation paging to eMTC terminal into
Row tests the speed.
For not across eNB scene, i.e. UE is arrived in paging to eNB again at this eNB, then it can be disposed and be spaced according to different community
Distance and paging interval time can test the speed for eMTC terminal.
For across eNB scene, i.e. history eNB can not be paged at this eNB to UE, then the history that can be stopped the UE is small
The information such as area's information (optional geographical location information) and release time last time are sent to other eNB by interface, while triggering it
His eNB initiates paging, so that the target eNB of UE can be according to cell deployment spacing distance between different eNB and paging interval time
It can test the speed for eMTC terminal.
Alternatively, triggering other eNB if eNB can not be paged at this eNB to UE and initiating paging, while receiving other
ENB pages feedback information, so that eNB can be able to be according to cell deployment spacing distance between different eNB and paging interval time
EMTC terminal tests the speed.
Furthermore, it is possible to there is the case where final paging is less than terminal, at this time it is considered that UE has moved out eNB and its week
Side eNB coverage area (including having carried out TAU update), i.e. UE is in the paging time interval moved at least into eNB and its week
Except the eNB coverage area of side, its rate can be estimated at this time.For example, according to the side of historical cell position and coverage area
Maximum distance and paging interval time between edge position estimate the movement speed of eMTC terminal.
