Fig. 2 is the schematic diagram of apparatus of the present invention embodiment;
Fig. 3 is another schematic diagram of apparatus of the present invention embodiment.
Embodiment
Basic thought of the present invention is when whether the network side judgement inserts new user or business, for network side provides the more control factor, thereby to make network side flexible way judgement user's access more.
For making those skilled in the art understand the present invention better, method provided by the invention is specified below in conjunction with embodiment more specifically.Fig. 1 is the flow chart of embodiment.
In step 11, adopt the uplink/downlink sub-carriers load of the mode calculation plot that triggers.
Business in can the sub-district increases/removes as trigger condition, when the business in the sub-district increase/trigger network stresses the traffic load of new calculation plot when removing;
User in also can the sub-district leaves as trigger condition, and trigger network stresses the traffic load of new calculation plot when having the user to leave in the sub-district;
Perhaps, directly insert the sub-district as trigger condition with new user, when new user wishes to insert the sub-district, the current business of trigger network side calculation plot load.
At up direction, all the professional upstream rate summations that can utilize the sub-district to admit are represented the uplink service load condition of sub-district.For example, suppose that the business of having admitted in the sub-district has 3, the upstream rate that 3 business are asked is respectively 100kbps (kilobits/second), 200kbps and 300kbps, and then the uplink service of sub-district load is 600kbps.
At up direction, also can utilize all users' that the sub-district has been admitted received power summation to represent the uplink service load condition of sub-district.For example, suppose that the user who has admitted in the sub-district has 3, to 3 users' received power be respectively 0.1w (watt), 0.1w and 0.2w, then the uplink service of sub-district load is 0.4w.
At down direction, correspondingly, all the professional downstream rate summations that can utilize the sub-district to admit are represented the downlink business load condition of sub-district, perhaps utilize all users' that the sub-district has been admitted transmitted power summation to represent the downlink business load condition of sub-district.
In step 12, when new user wishes to insert the sub-district, determine the uplink/downlink sub-carriers load that the sub-district is current.
The uplink/downlink sub-carriers load that network side can the lastly calculate is as the current uplink/downlink sub-carriers load in sub-district.Network side also can calculate new user earlier and insert the uplink/downlink sub-carriers load increment that the sub-district causes, on the basis of the uplink/downlink sub-carriers of the last time load result of calculation, increase described uplink/downlink sub-carriers load increment then, with the uplink/downlink sub-carriers load of new acquisition as the current uplink/downlink sub-carriers load in sub-district.
It is to be noted: if in step 11, insert the sub-district as trigger condition with new user, then when new user wishes to insert the sub-district, the cell uplink that network side calculates/downlink business load calculates for the last traffic load, and the cell uplink that this moment, network side calculated/downlink business load is exactly the current uplink/downlink sub-carriers load in sub-district.
In step 13, determine the corresponding access probability of uplink/downlink sub-carriers load that the sub-district is current.
The uplink and downlink traffic load situation of sub-district and the corresponding relation of access probability set in advance.When the corresponding relation of Zone load condition and access probability is set, at first divide the traffic load grade separately for the uplink and downlink traffic load of sub-district, the access probability of a correspondence is set for each traffic load grade then.When all professional upstream rate summations of utilizing the sub-district to admit are represented the uplink service load condition of sub-district, suppose the sub-district the maximum receiving velocity that can provide be 1200kbps, can be with receiving velocity (0kbps, 400kbps], (400kbps, 800kbps], (800kbps, 1200kbps) be set to 3 traffic load grades, can access probability 1,0.7,0 be set respectively for 3 traffic load grades.Suppose that the business of having admitted in the sub-district has 3, the upstream rate that 3 business are asked is respectively 100kbps, 200kbps and 300kbps, and then the uplink service of sub-district load is 600kbps, and this moment, corresponding access probability was 0.7.If have new user to wish to insert the sub-district this moment, then will carry out this user's up access judgement with 0.7 access probability.Suppose that the upstream rate that 3 business are asked is respectively 200kbps, 300kbps and 400kbps, then the uplink service of sub-district load is 900kbps, and this moment, corresponding access probability was 0.If have new user to wish to insert the sub-district this moment, then refuse to insert this user at up direction.Suppose that the upstream rate that 3 business are asked is respectively 100kbps, 100kbps and 100kbps, then the uplink service of sub-district load is 300kbps, and this moment, corresponding access probability was 1.If have new user to wish to insert the sub-district this moment, then can directly obtain to insert and permit at up direction.
Correspondingly, when all professional downstream rate summations of utilizing the sub-district to admit are represented the downlink business load condition of sub-district, suppose the sub-district the maximum transmission rate that can provide be 2000kbps, can be with transmission rate (0kbps, 800kbps], (800kbps, 1000kbps], (1000kbps, 1600kbps], (1600kbps, 2000kbps) be set to 4 traffic load grades, can access probability 1,0.9,0.5,0 be set respectively for 4 traffic load grades.Suppose that the business of having admitted in the sub-district has 3, the downstream rate that 3 business are asked is respectively 200kbps, 300kbps and 500kbps, and then the downlink business of sub-district load is 1000kbps, and this moment, corresponding access probability was 0.9.If have new user to wish to insert the sub-district this moment, then will carry out this user's descending access judgement with 0.9 access probability.Suppose that the downstream rate that 3 business are asked is respectively 500kbps, 800kbps and 400kbps, then the downlink business of sub-district load is 1700kbps, and this moment, corresponding access probability was 0.If have new user to wish to insert the sub-district this moment, then refuse to insert this user at down direction.Suppose that the downstream rate that 3 business are asked is respectively 200kbps, 300kbps and 300kbps, then the downlink business of sub-district load is 800kbps, and this moment, corresponding access probability was 1.If have new user to wish to insert the sub-district this moment, then can directly obtain to insert and permit at down direction.
When reception/transmitted power summation of utilizing all users that the sub-district has been admitted represent the sub-district on/during the downlink business load condition, can the rest may be inferred, no longer repeat specification here.
Wherein, the setting that should be inversely proportional to of the traffic load grade access probability corresponding with it, that is, the traffic load grade is low more, and the access probability of this grade correspondence should be high more.
In step 14, described user is adjudicated in the access of up/down direction with the sub-district corresponding access probability of current uplink/downlink sub-carriers load.
Adoptable a kind of method is:
For up direction, in span [0,1], generate a number at random, if when the described number that generates is at random loaded pairing access probability greater than the current uplink service of sub-district, then refuse to insert described user at up direction; Otherwise, permit inserting described user at up direction.
For example, the current uplink service of the supposing the sub-district pairing access probability P=0.7 that loads is if the several x=0.7 that generate at random for up direction in step 14 then permit inserting described user at up direction; If several x=0.8 of Sheng Chenging then refuse to insert described user at up direction at random.
For down direction, in span [0,1], generate a number at random, if when the described number that generates is at random loaded pairing access probability greater than the current downlink business of sub-district, then refuse to insert described user at down direction; Otherwise, permit inserting described user at down direction.
When the uplink and downlink direction is all permitted described user and inserted, insert described user.
In the above-described embodiments, network side adopts the traffic load of triggering mode calculation plot, the also traffic load of calculation plot periodically of network side when practical application.
In the above-described embodiments, with on all business of actual measurement in the sub-district/the downstream rate summation, or the summation of the needed reception/transmitted power of all users of actual measurement, the traffic load situation of expression sub-district.In actual applications, also can not adopt actual measured value and relative value after adopting normalization is represented the traffic load situation of sub-district.
On the sub-district/the downlink business load condition can by on all business of having admitted in the sub-district/downstream rate summation and this sub-district the ratio value representation of the maximum reception/transmission rate that can provide.For example, suppose that the business of having admitted in the sub-district has 3, the upstream rate that 3 business are asked is respectively 100kbps, 200kbps and 300kbps; The maximum receiving velocity that this sub-district can provide is 1000kbps, and then the uplink service of sub-district load is (100+200+300)/1000=0.6.
If the relative value after the employing normalization is represented the traffic load situation of sub-district, then when pressing the traffic load degree, also should correspondingly carry out normalization and handle the traffic load divided rank of sub-district.
Suppose the sub-district the maximum receiving velocity that can provide be 1000kbps, can with (0/1000,400/1000], (400/1000,800/1000], (800/1000,1000/1000), promptly (0,0.4], (0.4,0.8], (0.8,1) be set to 3 traffic load grades.
In the above-described embodiments, know nothing for the information of other sub-district each sub-district.And for the mobile network of distributed structure/architecture, when system's actual motion, may carry out a certain amount of information interaction between each sub-district, and the information between a plurality of sub-districts of same NodeB under covering can be shared.In this case, a sub-district can utilize the traffic load information of its neighbor cell, and auxiliary this sub-district is carried out the user and inserted judgement.
For example, if the traffic load that its neighbor cell is learnt in sub-district is heavier, then can reduce the pairing access probability of each uplink/downlink sub-carriers load level of this sub-district, to reduce the phase mutual interference of minizone as far as possible; On the contrary,, then can improve the pairing access probability of each uplink/downlink sub-carriers load level of this sub-district, utilize system resource as much as possible if the traffic load that its neighbor cell is learnt in sub-district is lighter.Wherein, interactive service information on load periodically between each neighbor cell also can adopt trigger-type to carry out the mutual of traffic load information.
In addition, because the bandwidth and the available resources of each sub-district are not quite similar, therefore can pass through O﹠amp; M (operation and maintenance) center is provided with its traffic load grade and corresponding access probability according to the actual conditions of each sub-district separately for each sub-district, and the optimum parameters configuration can be determined by system emulation.
Based on said method, the device that the present invention also provides a kind of user of judgement to insert, Fig. 2 is this schematic representation of apparatus, this device comprises traffic load determining unit S21, access probability determining unit S22 and inserts decision unit S23.
Traffic load determining unit S21 can triggering mode or the uplink/downlink sub-carriers load of calculation plot periodically.
With the traffic load of triggering mode calculation plot the time, the business in can the sub-district increases/removes as trigger condition, when the business in the sub-district increase/trigger network stresses the traffic load of new calculation plot when removing;
User in also can the sub-district leaves as trigger condition, and trigger network stresses the traffic load of new calculation plot when having the user to leave in the sub-district;
Perhaps, directly insert the sub-district as trigger condition with new user, when new user wishes to insert the sub-district, the current business of trigger network side calculation plot load.
At up direction, all the professional upstream rate summations that can utilize the sub-district to admit are represented the uplink service load condition of sub-district, also can utilize all users' that the sub-district has been admitted received power summation to represent the uplink service load condition of sub-district.
At down direction, correspondingly, all the professional downstream rate summations that can utilize the sub-district to admit are represented the downlink business load condition of sub-district, perhaps utilize all users' that the sub-district has been admitted transmitted power summation to represent the downlink business load condition of sub-district.
In actual applications, also can not adopt actual measured value and relative value after adopting normalization is represented the traffic load situation of sub-district.
The uplink service load than value representation sub-district of the maximum receiving velocity that all the professional upstream rate summations that can admit by the sub-district and sub-district can provide, all professional downstream rate summations of having admitted by the sub-district are loaded with the downlink business than value representation sub-district of the maximum transmission rate that the sub-district can provide.
Perhaps, the uplink service load than value representation sub-district of received power summation with receiver Gaussian noise by all users that the sub-district has been admitted, the downlink business than value representation sub-district of the maximum transmit power that transmitted power summation and the sub-district by all users that the sub-district has been admitted can provide is loaded.
When new user wishes to insert the sub-district, traffic load determining unit S21 will determine the uplink/downlink sub-carriers load that the sub-district is current.Traffic load determining unit S21 can be the last traffic load result of calculation as the current uplink/downlink sub-carriers load in sub-district, also can calculate new user earlier and insert the uplink/downlink sub-carriers load increment that the sub-district causes, on the basis of the uplink/downlink sub-carriers of the last time load result of calculation, increase described uplink/downlink sub-carriers load increment then, and with the uplink/downlink sub-carriers load of new acquisition as the current uplink/downlink sub-carriers load in sub-district.
It is to be noted: if traffic load determining unit S21 inserts the sub-district as trigger condition with new user, then when new user wishes to insert the sub-district, the cell uplink that traffic load determining unit S21 calculates/downlink business load calculates for the last traffic load, and the cell uplink that this moment, traffic load determining unit S21 calculated/downlink business load is exactly the current uplink/downlink sub-carriers load in sub-district.
After obtaining the current traffic load in sub-district, the uplink/downlink sub-carriers load that access probability determining unit S22 will be current according to the sub-district is determined corresponding access probability.
The uplink and downlink traffic load situation of sub-district and the corresponding relation of access probability set in advance.When the corresponding relation of Zone load condition and access probability is set, at first be that up, the downlink business load of sub-district divided the traffic load grade separately, the access probability of a correspondence is set for each traffic load grade then.
Can utilize all business that the sub-district admitted on/the downstream rate summation represent the sub-district on/the downlink business load condition, also can utilize reception/transmitted power summation of all users that the sub-district admitted represent the sub-district on/the downlink business load condition.
Wherein, the setting that should be inversely proportional to of the traffic load grade access probability corresponding with it, that is, the traffic load grade is low more, and the access probability of this grade correspondence should be high more.
Inserting decision unit S23 will adjudicate in the access of up/down direction described user with the sub-district corresponding access probability of current uplink/downlink sub-carriers load.Inserting decision unit S23 can be at up/down direction, in span [0,1] generates a number at random,, then refuse to insert described user at up/down direction if when the described number that generates is at random loaded pairing access probability greater than the current uplink/downlink sub-carriers of sub-district; Otherwise, permit inserting described user at up/down direction.
Described device can also comprise that is inserted a performance element, when inserting decision unit S23 judgement uplink and downlink direction and all permit described user and insert, inserts performance element and will carry out described user's access.
In the above-described embodiments, know nothing for the information of other sub-district each sub-district.And for the mobile network of distributed structure/architecture, when system's actual motion, may carry out a certain amount of information interaction between each sub-district, and the information between a plurality of sub-districts of same NodeB under covering can be shared.In this case, a sub-district can utilize the traffic load information of its neighbor cell, and auxiliary this sub-district is carried out the user and inserted judgement.
