Description
Technical field
The present invention relates to LTE communication technical field, relate in particular to a kind of edge customer attribute determining method and device.
Background technology
Long Term Evolution (Long Term Evolution, LTE) system descending transfer of data adopts OFDM (OFDMA) technology as transmission means, and transmitting uplink data adopts single-carrier frequency division multiple access (SC-FDMA) technology as transmission means.These multiple access technologies utilize the orthogonality between frequency, make in theory, and between this community user, be non-interfering.All users disturb and are mainly derived from the co-channel interference that other edge customers that use community, especially this community of same frequency resources can be subject to serious neighbor cell.LTE system is using the performance of improving Cell Edge User as an importance improving throughput of system performance, and for the performance that how to improve edge customer, proposed a lot of solutions.Its frequency domain Inter-Cell Interference Coordination (Inter-Cell Interference Coordination, ICIC) technology is exactly by the orthogonalized a kind of interference coordination technique of edge customer frequency range used.
In order to guarantee effectively carrying out of Inter-Cell Interference Coordination technology, need to first to the attribute of subscriber equipment in community (User Equipment, UE), carry out correct division, define the edge customer in community.
In existing technology of dividing for user property, there are three kinds of relevant processing methods, method one is that Signal to Interference plus Noise Ratio (Signal to Interference plus Noise Ratio, the SINR) value based on user is carried out the division of edge customer and central user; Method two is that the path loss difference based on UEDao Zhe community and adjacent cell is carried out the judgement of user property; Method three is that the CQI or the MCS grade that based on UE, report are carried out the judgement of user property.Below these three kinds of methods are described in detail:
Method one, all users' Signal to Interference plus Noise Ratio SINR in calculation plot, according to Signal to Interference plus Noise Ratio thresholding SINR
thresholdthe central user of division of cells and edge customer.Wherein Signal to Interference plus Noise Ratio be calculated as follows formula,
wherein, H
lfor the channel gain matrix of Serving cell to user l, w
lthe pre-coding matrix of Serving cell, P
lfor the transmitted power of Serving cell, H
kfor the channel gain matrix of community k to user l, w
kfor the pre-coding matrix of community k, P
kfor the transmitted power of community k, N is noise power, || || represent function wherein to get norm.Work as SINR
i>=SINR
thresholdsigh.During throat, user l is Cell Center User; Otherwise, be edge customer, wherein threshold value is by default.This user property based on Signal to Interference plus Noise Ratio is determined method, need to estimate the channel gain matrix of this community, the channel gain matrix of adjacent cell and noise power, also need to measure transmitting power and the pre-coding matrix of adjacent cell, algorithm is realized very difficult, and amount of calculation is large.
Method two, the base station in this community is p1 to user's path loss, the community nearest with community is p2 to this user's path loss, if p2-p1>x, region centered by this user region; If p2-p1<x, the fringe region of this Wei Zhe community, user region; If p2-p1=x, the central area of this Wei Zhe community, user region and the border of fringe region, wherein x is default path loss threshold value.Path loss difference based on UEDao Zhe community and adjacent cell is carried out the judgement of user property, need to estimate this community and the adjacent cell path loss to this user, and algorithm is realized difficulty.
Method three, UE is by measuring cell special reference (Cell-specific reference signals, CRS) obtain descending channel quality information, and reported to base station, this channel quality information can adopt channel quality indication (Channel Quality Indicator, CQI) grade or modulation coding mode (Modulation and coding scheme, MCS) grade is represented; The attribute that UE is carried out according to channel quality information in base station is divided.But this CQI reporting based on UE or MCS grade are carried out the judgement of user property, not accurate enough to user's attribute division, certain requirement of giving the correct time on CQI or MCS, for example, just, switch to the UE of this community, understand because not reporting in time CQI or MCS, and be not divided into edge customer.

Embodiment
In order to provide algorithm, realize simple, the implementation of again can be in real time and accurately the UE of access base station being carried out to attribute differentiation, the embodiment of the present invention provides a kind of edge customer attribute determining method and device, below in conjunction with Figure of description, the preferred embodiments of the present invention is described.
Consult shown in Fig. 1, in the embodiment of the present invention, it is as follows that the definite idiographic flow of edge customer attribute is carried out in base station:
Step 100: base station is issued to the measurement configuration information based on event A2 each UE of this base station of access, should the measurement configuration information based on event A2 at least comprise triggering rule.
Concrete, the UE that accesses this base station is receiving that Radio Resource control connection reprovision completes (RRC Connection Reconfiguration Complete) message, complete RRC (Radio Resource Control, Radio Resource control) after connecting, the base station of Serving cell is issued to the measurement configuration information based on event A2 the UE of this base station of access, for these UE configuration event A2 triggers periodic report, the above-mentioned measurement configuration information based on event A2 at least comprises triggering rule, this triggering rule comprises report cycle, report number of times, trigger thresholding and trigger duration etc.
Wherein, event A2 (Event A2) is defined as: Serving cell is worse than absolute door limit value (Serving becomes worse than threshold), be used for representing that Serving cell signal quality is lower than setting thresholding, when the event that meets this condition is reported, Node B (eNodeB) starts different frequency/different system measurement.
Meeting event entry condition: during Ms+Hys<threshold_RSRP, UE triggers periodic report next time;
Leave condition meeting event: during Ms-Hys>threshold_RSRP, UE can not trigger periodic report next time;
Wherein, Ms is the measurement parameter of Serving cell, as adopted Reference Signal Received Power (Reference signal received power, RSRP) value or Reference Signal Received Quality (Reference signal received quality, RSRQ) value etc., below adopt RSRP value to be introduced, unit is dBm; Hys is sluggish, and unit is dB; Threshold_RSRP is for triggering thresholding, and unit is dBm, and in embodiments of the present invention, this absolute door limit value is also the triggering thresholding in the embodiment of the present invention.
Step 110: base station receives the first measurement parameter that each UE returns according to the measurement configuration information based on event A2, and start respectively the timer arranging for each UE.
Concrete, the attribute of determining UE be edge customer or centered by user according to the current state of UE, constantly change, therefore, the process of determining UE attribute is also constantly to change, in the embodiment of the present invention, will be divided into a unlimited determination cycles, constantly the attribute of UE is judged, below all be take in a determination cycles as example is introduced.
Concentrated in order the new UE of access and switching to be added for judging candidate's edge customer of edge customer in time, adopt following solution:
Each UE is when the base station of access service community, capital receives the measurement configuration information based on event A2 that the base station of Serving cell is its configuration, and the new UE that switches and newly access is probably edge customer, therefore, new switch and the UE of new access concentrates rigidly connecting the fashionable candidate's edge customer that will add, at new UE, complete after RRC connection, base station receives that RRC connection has configured after message, directly new UE is added candidate's edge customer to concentrate, and for new UE, corresponding timer is set, and before carrying out decision for new UE for the first time, whether the timer that judgement arranges for new UE is overtime, if so, when definite new UE does not return to the second measurement parameter, new UE is deleted from candidate's edge customer collection, otherwise, directly for new UE, carry out decision.
Above-mentioned flow process is only used when UE newly accesses and newly switches to this base station, be that new UE adds when determination cycles just starts, probably at the timer due in of new UE with regard to reporting measurement parameter, the new UE of reporting measurement parameter continues to be retained in candidate's edge customer and concentrates, need to rejecting from candidate's edge customer is concentrated of reporting measurement parameter, does not participate in edge customer and judges; If new UE adds when determination cycles finishes soon, at the timer of new UE due in not, arrive the finish time of determination cycles, do not need return measurement parameter by the time, using new UE as judging object, participates in edge customer and judge equally.After system stability, other UE judge edge customer by report measurement information.
The base station of Serving cell receives the first measurement parameter that each UE under this Serving cell returns according to the measurement configuration information based on event A2, what the first measurement parameter adopted here is RSRP value, each UE under this Serving cell refers to the UE of new switching and new access, and other belong to the UE of base station, the base station of Serving cell, after receiving RSRP value, is kept at this locality.At each UE, report after the first measurement parameter, start respectively the timer arranging for each UE.
And under the base station of Serving cell except the UE of new switching and new access, the RSRP value that other UE measure in first fit event entry condition constantly, needn't report RSRP value at once, but need through triggering after duration (TimeToTrigger), the periodic report of ability trigger event A2, wherein, above-mentioned report cycle is greater than this triggering duration.Like this can be so that those RSRP values float on and trigger the upper and lower UE of thresholding and do not report to base station, but carry out again the periodic report of measurement parameter continue to reach lower than trigger gate limit for length the triggering duration of setting in RSRP value after, can reduce communicating by letter between UE and base station, thereby minimizing takies Internet resources, and can save the energy consumption of UE.
Consult shown in Fig. 2, curved portion represents the RSRP value that UE self measures, this RSRP value with sluggish with meet the trigger gate limit value moment, start timing, wherein, can adopt RSRP value and triggering thresholding directly to judge, also can add sluggishness and RSRP value together to judge with triggering thresholding; The measurement parameter of determining this UE after triggering duration continues to prescribe a time limit lower than trigger gate, trigger periodic report, wherein, the number of times reporting is set to unlimited reporting, the measurement parameter of moment UE after meet triggering thresholding is all lower than triggering thresholding, therefore, and according to report cycle, the unlimited RSRP value to UE reports, until this RSRP value meets event, leaves condition.
Step 120: the first measurement parameter that base station is returned according to triggering rule and each UE judged respectively before the timer expiry of corresponding UE, whether receive that corresponding UE returns for trigger the second measurement parameter reporting next time, and the UE that returns to the second measurement parameter is added to candidate's edge customer collection.
Concrete, after receiving the first measurement parameter that each UE returns, before the timer of corresponding UE is not overtime, judge whether to receive that corresponding UE is because meeting the second measurement parameter of triggering rule periodic report, this first measurement parameter is in RSRP value, to continue to report after triggering thresholding and continuing to triggering duration with other UE the new UE switching except above-mentioned new access, the UE of new access and the new UE switching can regard as and report the first measurement parameter and directly added candidate's edge customer collection rigidly connecting into this base station constantly, together with other UE, in base station, receive after the first measurement parameter, start the timer of corresponding UE, if measuring the RSRP value of self, corresponding UE continues lower than triggering thresholding, corresponding UE can continue to report to base station the second measurement parameter according to report cycle, if corresponding UE measures the RSRP value of self higher than triggering thresholding, UE no longer reports the RSRP value of self to base station.Therefore, whether base station, after receiving and preserve the first measurement parameter that UE reports, before judging the timer expiry of corresponding UE, receives the second measurement parameter that it reports, and by receiving, reports the UE of the second measurement parameter to add candidate's edge customer collection.Wherein, the timing length of this timer is greater than report cycle.
Step 130: edge customer sum, according to the determination cycles of setting, is judged according to default edge bandwidth ratio in base station, and candidate's edge customer concentrates the priority of each UE, and choose successively with the UE of edge customer sum similar number and be judged to be edge customer.
Concrete, according to the determination cycles of setting, judge that the UE that does not return to the second measurement parameter before the timer expiry of corresponding UE is directly defined as central user, until meet event entry condition before all no longer to base station periodic report measurement parameter, the RSRP value that base station can be reported is simultaneously deleted in base station.
Add the concentrated UE of candidate's edge customer, also need further to confirm finally to determine the attribute of UE through base station.From candidate's edge customer, concentrate and determine that the flow process of edge customer number is as follows:
The concentrated number of users N of judgement candidate's edge customer
hwhether be less than or equal to default edge bandwidth minimum service number of users b;
If so, by the concentrated number of users N of candidate's edge customer
has edge customer sum N;
Otherwise, according to default edge bandwidth ratio
determine the number of users N of this base station of access
tin theoretical margin number of users, and choose the concentrated number of users N of candidate's edge customer
has the first numerical value, and choose higher value in the first numerical value and edge bandwidth minimum service number of users b as edge customer sum N with smaller value in theoretical margin number of users.
Above-mentioned flow process can represent with following formula:
For example,
b=3, N
t=6, if N
h=2 (being less than b), so N=2; If N
h=4 (being greater than b), so N=max (3, min (4,2))=3.
For another example,
b=3, N
t=12, if N
h=3 (equaling b), so N=2; If N
h=5 (being greater than b), so N=max (3, min (5,4))=4.
Determine after edge customer sum, according to candidate's edge customer, concentrate the priority of each UE, choose successively with the UE of edge customer sum similar number and be defined as edge customer, choose process as follows:
Consult shown in Fig. 3, according to candidate's edge customer, concentrate the priority of each UE to sort, conventionally from other communities, newly switch to the base station of this community, can determine that this UE mono-is decided to be edge customer; And report the UE of himself RSRP value, its RSRP value is lower show this UE from center of housing estate more away from, therefore, the priority of each UE is respectively from high in the end: the UE that newly switches to this base station, return to each UE of the second measurement parameter and the UE that newly accesses this base station, wherein, the priority of returning to each UE of the second measurement parameter is to determine from low to high according to the second measurement parameter returning from high to low; By the concentrated UE of candidate's edge customer according to above-mentioned prioritization after, according to the priority of each UE, choose from high to low with the UE of edge customer sum similar number and be defined as edge customer successively.
Above-mentioned flow process is the process of determining user property in a determination cycles, but the UE in Serving cell is continuous movement, state constantly changes, therefore, the process of judging user property is a continual process, therefore, and in the embodiment of the present invention, the process of judging user property is divided into numerous determination cycles, and this determination cycles is the duration that is greater than above-mentioned timer.Above-mentioned only introduction in a determination cycles, the process of judgement user property.
In the process of actual definite user property, the UE that attribute can be changed adds in some community sets, for use in next step statistic processes, for example, when the central user in a upper determination cycles is judged to be to the edge customer of current determination cycles, this UE is added and is increased to Cell Edge User set (add to cell edge set), when the edge customer in a upper determination cycles is judged to be to the central user of current determination cycles, this UE is added and deletes Cell Edge User set (remove from cell edge set), in current determination cycles, add to cell edge set and remove from cell edge set are inputed to power control module and packet scheduling algorithm module, so that follow-up power adjustment and packet scheduling are processed.
Above-mentioned in determination cycles, edge user's processing procedure is as follows: current determination cycles determine the UE of access base station be edge customer or centered by after user, the first edge customer collection that the definite edge customer of current determination cycles is formed compares with the second edge customer collection of the determined edge customer composition of a upper determination cycles;
Judge that whether the first edge customer collection is identical with the second edge customer collection;
At the first edge customer collection, when different, the first edge customer collection is updated to the second edge customer collection from the second edge customer collection, and the second edge customer collection is inputted to relevant functional module is used for processing in next determination cycles.
Below in conjunction with accompanying drawing, with specific embodiment, device provided by the invention is described in detail.
