Description
Technical field
The present invention relates to LTE communication technical field, more particularly to a kind of edge customer attribute determining method and device.
Background technology
Long Term Evolution (Long Term Evolution, LTE) system descending data transfer uses OFDM
(OFDMA), used as transmission means, transmitting uplink data is using single-carrier frequency division multiple access (SC-FDMA) technology as transmission side for technology
Formula.These multiple access technologies are using the orthogonality between frequency so that be in theory, between this community user non-interfering.
All user's interference are mainly derived from other cell for using same frequency resources, especially edge customers of this cell and can be subject to
The co-channel interference of serious neighbor cell.The performance that LTE system will improve Cell Edge User is gulped down as improvement system
One importance of the amount of telling performance, and for how improving the performance of edge customer, it is proposed that many solutions.Its intermediate frequency
Domain Inter-Cell Interference Coordination (Inter-Cell Interference Coordination, ICIC) technology is exactly by edge customer
A kind of interference coordination technique of frequency range orthogonalization used.
In order to ensure effectively carrying out, it is necessary to first to intra-cell users equipment (User for Inter-Cell Interference Coordination technology
Equipment, UE) attribute correctly divided, specify the edge customer in cell.
In the existing technology divided for user property, there are three kinds of processing methods of correlation, method one is based on use
Signal to Interference plus Noise Ratio (Signal to Interference plus Noise Ratio, the SINR) value at family is carried out
The division of edge customer and central user；Method two is the path loss difference based on UE to this cell and adjacent cell carries out user property
Judgement；Method three is CQI the or MCS grades that are reported based on UE carries out the judgement of user property.Below to these three methods
It is described in detail：
Method one, calculates the Signal to Interference plus Noise Ratio SINR of all users in cell, according to Signal to Interference plus Noise Ratio thresholding SINRthresholdDraw
Divide the central user and edge customer of cell.Wherein Signal to Interference plus Noise Ratio is calculated as follows formula,

Specific embodiment
Realized simply to provide algorithm, but energy is real-time and accurately the UE to access base station carries out the realization side of attribute differentiation
Case, the embodiment of the invention provides a kind of edge customer attribute determining method and device, below in conjunction with Figure of description to this hair
Bright preferred embodiment is illustrated.
Refering to shown in Fig. 1, in the embodiment of the present invention, the idiographic flow that base station carries out edge customer attribute determination is as follows：
Step 100：Measurement configuration information based on event A2 is issued to each UE for accessing this base station for base station, and this is based on
The measurement configuration information of event A2 comprises at least triggering rule.
Specifically, the UE for accessing this base station is receiving wireless heterogeneous networks connection again with completion (RRC Connection
Reconfiguration Complete) message, complete RRC (Radio Resource Control, wireless heterogeneous networks) even
After connecing, the measurement configuration information based on event A2 is issued to the UE for accessing this base station for the base station of Serving cell, is that these UE match somebody with somebody
Event A2 triggering periodic reports are put, the above-mentioned measurement configuration information based on event A2 comprises at least triggering rule, triggering rule
Including report cycle, report number of times, triggering thresholding and triggering duration etc..
Wherein, the definition of event A2 (Event A2) is：Serving cell is worse than absolute threshold value (Serving becomes
Worse than threshold), for representing that serving cell signal quality, less than setting thresholding, meets the event quilt of this condition
On give the correct time, node B (eNodeB) start different frequency/different system measurement.
Meeting event entry condition：Ms+Hys<During threshold_RSRP, UE triggers periodic report next time；
Condition is left event is met：Ms-Hys>During threshold_RSRP, UE will not trigger periodic report next time；
Wherein, Ms is the measurement parameter of Serving cell, can such as use Reference Signal Received Power (Reference
Signal received power, RSRP) value or Reference Signal Received Quality (Reference signal received
Quality, RSRQ) value etc., it is introduced using RSRP values below, unit is dBm；Hys is sluggishness, and unit is dB；
Threshold_RSRP is triggering thresholding, and unit is dBm, and in embodiments of the present invention, the absolute threshold value namely the present invention are real
Apply the triggering thresholding in example.
Step 110：Base station receives the first measurement parameter that each UE is returned according to the measurement configuration information based on event A2,
And it is respectively started the timer set for each UE.
Specifically, determine UE attribute for edge customer or centered on user be to be continually changing according to the current states of UE
, accordingly, it is determined that the process of UE attributes is also what is be continually changing, unlimited judgement cycle is classified into the embodiment of the present invention, no
Attribute disconnectedly to UE judges, is all introduced as a example by a judgement cycle below.
In order to the new UE that can be accessed in time and switch adds the candidate edge user for judging edge customer to concentrate,
Using solution below：
At the base station of access service cell, the base station that can all receive Serving cell is its configuration based on thing to each UE
The measurement configuration information of part A2, and newly switch and the UE that newly accesses is likely to be edge customer, therefore, new switching and newly connect
The UE for entering rigid connection it is fashionable will add candidate edge user concentrate, i.e., new UE complete RRC connection after, base station receive RRC company
After connecing configuration completion message, directly add candidate edge user to concentrate new UE, and corresponding timer is set for new UE, with
And before first time performs decision for new UE, whether judgement is overtime for the timer that new UE is set；If so, then existing
It is determined that when new UE does not return to the second measurement parameter, new UE being collected from candidate edge user and being deleted；Otherwise, performed directly against new UE
Decision.
Above-mentioned flow is only newly accessed in UE and used when newly switching to this base station, i.e., new UE adds when just starting in the judgement cycle
Enter, it is likely that new UE timer due in regard to reporting measurement parameter, the new UE of reporting measurement parameter remains in time
Select edge customer to concentrate, concentrated from candidate edge user the need for non-reporting measurement parameter and rejected, edge customer judgement is not participated in；
If new UE is added at the end of judging that the cycle is fast, in the non-due in of the timer of new UE, judge that the finish time in cycle has arrived,
Return measurement parameter is then needed not wait for, equally using new UE as determine object, edge customer is participated in and is judged.Treat system stabilization
Afterwards, other UE judge edge customer by report measurement information.
Each UE that the base station of Serving cell is received under the Serving cell is returned according to the measurement configuration information based on event A2
Return the first measurement parameter, here the first measurement parameter use RSRP values, each UE under the Serving cell is referred to newly
Switch and the new UE for accessing, and other belong to the UE of base station, the base station of Serving cell is preserved after RSRP values are received
Local.After each UE reports the first measurement parameter, the timer set for each UE is respectively started.
And except new switching and the new UE for accessing under the base station of Serving cell, the RSRP values of other UE measurements are in first fit
The event entry condition moment, it is not necessary to report RSRP values at once, but need after triggering duration (TimeToTrigger),
The periodic report of trigger event A2, wherein, above-mentioned report cycle is more than the triggering duration.Can so cause that those RSRP values are floated
Move and do not reported to base station in the upper and lower UE of triggering thresholding, but when RSRP values are consistently less than trigger gate limit for length up to the triggering for setting
The periodic report of parameter is measured after length again, it is possible to reduce the communication between UE and base station, so as to reduce be accounted for Internet resources
With, and the energy consumption of UE can be saved.
Refering to shown in Fig. 2, curved portion represents a RSRP value for UE itself measurements, the RSRP values with it is sluggish and expire
At the foot triggering threshold value moment, start timing, wherein it is possible to directly judge with triggering thresholding using RSRP values, it is also possible to which it is slow to add
Stagnant and RSRP values together judge with triggering thresholding；Determine that the measurement parameter of the UE is consistently less than triggering thresholding after triggering duration
When, periodic report is triggered, wherein, the number of times that will be reported is set to report infinitely, the moment UE's after triggering thresholding is met
Measurement parameter is all less than triggering thresholding, therefore, according to report cycle, RSRP values to UE are reported infinitely, until
The RSRP values meet event and leave condition.
Step 120：Base station judges in corresponding UE respectively according to the first measurement parameter that triggering rule and each UE are returned
Timer expiry before, if receive that corresponding UE returns for triggering the second measurement parameter for reporting next time, and will return
The UE for returning the second measurement parameter adds candidate edge user collection.
Specifically, after the first measurement parameter for receiving each UE returns, before the timer of corresponding UE has not timed out, sentencing
Whether disconnected to receive the second measurement parameter that corresponding UE triggers regular periodic report because meeting, first measurement parameter is except above-mentioned new
Access and newly other UE outside the UE of switching are consistently less than triggering thresholding and continue to triggering duration to report in RSRP values
, the UE of the new UE for accessing and new switching rigid connection enter this base station moment can be regarded as having reported the first measurement parameter and
Candidate edge user collection is directly added into, together with other UE, after base station receives the first measurement parameter, starts the timing of corresponding UE
Device, if corresponding UE measures the RSRP values of itself and is consistently less than triggering thresholding, corresponding UE can continue to base station according to report cycle
The second measurement parameter is reported, if corresponding UE measures the RSRP values of itself higher than triggering thresholding, UE no longer reports itself to base station
RSRP values.Therefore, base station is after receiving and preserving the first measurement parameter that UE is reported, judge corresponding UE timer expiry it
Before, if its second measurement parameter for reporting is received, will be received and reported the UE of the second measurement parameter to add candidate edge user to collect.
Wherein, the timing length of the timer is more than report cycle.
Step 130：Base station judges that edge customer is total according to the judgement cycle of setting according to default edge bandwidth ratio
Number, and candidate edge user concentrates the priority of each UE, and selection is sentenced with the equal number of UE of edge customer sum successively
It is set to edge customer.
Specifically, according to the judgement cycle of setting, the second measurement ginseng is not returned to before the timer expiry for judging corresponding UE
Several UE are determined directly as central user, are all no longer measured to base station periodic report before meeting event entry condition and joined
Number, while the RSRP values that base station can be reported are deleted in a base station.
The UE for adding candidate edge user to concentrate, in addition it is also necessary to further confirm finally determine the category of UE by base station
Property.Concentrated from candidate edge user and determine that the flow of edge customer number is as follows：
Judge the number of users N that candidate edge user concentratesHWhether used less than or equal to default edge bandwidth minimum service
Amount b；
If so, the number of users N for then concentrating candidate edge userHAs edge customer sum N；
Otherwise, according to default edge bandwidth ratioIt is determined that accessing the number of users N of this base stationTIn theoretical margin user
Number, and choose the number of users N of candidate edge user concentrationHWith smaller value in theoretical margin number of users as the first numerical value, and
The higher value in the first numerical value and edge bandwidth minimum service number of users b is chosen as edge customer sum N.
Above-mentioned flow can be represented with below equation：
Wherein, round () is the fortune that rounds up
Calculate；
For example,B=3, NT=6, if NH=2 (being less than b), then N=2；If NH=4 (being more than b), then
N=max (3, min (4,2))=3.
For another example,B=3, NT=12, if NH=3 (being equal to b), then N=2；If NH=5 (being more than b), that
N=max (3, min (5,4))=4.
After determining edge customer sum, the priority of each UE is concentrated according to candidate edge user, chosen successively and edge
The equal number of UE of total number of users is defined as edge customer, chooses process as follows：
Refering to shown in Fig. 3, the priority for concentrating each UE according to candidate edge user is ranked up, generally from other cells
Newly switch to the base station of this cell, it may be determined that the UE mono- is set to edge customer；And report the UE, its RSRP of its own RSRP value
Value is lower show the UE from center of housing estate more away from, therefore, the priority of each UE is respectively from high in the end：Newly switch to this base station
UE, return to each UE of the second measurement parameter and newly access the UE of this base station, wherein, return to each of the second measurement parameter
The priority of UE is determined from low to high according to the second measurement parameter for returning；Candidate edge user is concentrated
After UE is according to above-mentioned prioritization, number identical with edge customer sum is chosen from high to low according to the priority of each UE successively
Purpose UE is defined as edge customer.
Above-mentioned flow is in a judgement cycle process for determining user property, but UE in Serving cell is continuous
Mobile, state constantly changes, therefore, the process for judging user property is a continual process, therefore, the present invention is real
Apply in example, the process for judging user property is divided into the numerous judgement cycle, the judgement cycle is greater than above-mentioned timer
Duration.It is above-mentioned to be only only presented in a judgement cycle, judge the process of user property.
During actual determination user property, the UE that attribute can change is added in some attribute sets, so as to
For the statistic processes of next step, for example, the central user in the upper judgement cycle to be judged to currently judge the edge in cycle
During user, the UE is added and increases to Cell Edge User set (add to cell edge set), the cycle is judged by upper one
In edge customer when being judged to currently judge the central user in cycle, the UE is added and deletes Cell Edge User set
(remove from cell edge set), by add to cell edge set and remove in the current judgement cycle
From cell edge set are input into power control module and packet scheduling algorithm module, in order to follow-up power adjustment and
Packet scheduling treatment.
It is above-mentioned in the judgement cycle, the processing procedure to edge customer is as follows：Determine access base station in the current judgement cycle
UE for edge customer or centered on after user, current will judge the first edge user of the edge customer composition that the cycle determines
Collect the second edge user collection constituted with edge customer determined by the upper judgement cycle to be compared；
Judge that whether identical first edge user collection collects with second edge user；
When first edge user collection is different from second edge user collection, first edge user collection is updated to second edge
User collects, and the related functional module of second edge user collection input is used for being processed in next judgement cycle.
