Description
Technical field
The present invention relates to the capacity-enlargement technology in wireless communication system, particularly relate to a kind of dilatation appraisal procedure and device of wireless communication system.
Background technology
At present, usually wireless resource utility efficiency is assessed with the occupied situation of wireless communication system physical carrier frequency resource, and wireless resource utility efficiency is the important reference of assessment wireless communication system service condition, be also wireless communication system dilatation or the important references index subtracting appearance.
Wireless resource utility efficiency assessment can for the resource usage characteristic of different network formats, the use of reasonable characterizing network Radio Resource and load condition.For global system for mobile communications (GSM, GlobalSystemforMobileCommunications), physical carrier frequency resource is split into multiple time slot according to time dimension, when a user uses GSM network to carry out communication service, one or more time slot will be taken.Therefore the wireless resource utility efficiency of gsm system adopts busy carrier frequency occupied timeslot number to assess: in timing statistics section, and community is the wireless resource utility efficiency of this community divided by the total number of timeslots that community can provide by the timeslot number that on average takies; For TD SDMA (TD-SCDMA, TimeDivision-SynchronousCodeDivisionMultipleAccess) system, physical carrier frequency resource is split into multiple code channel according to time and mutually orthogonal spreading code two dimensions, a user, when using TD-SCDMA system to carry out communication service, will take multiple code channel.Therefore the wireless resource utility efficiency of TD-SCDMA system adopts the occupied code channel number of busy to assess: namely in timing statistics section, the total wireless resource utility efficiency being this community of code channel that community can be provided divided by community by the code channel number on average taken; In like manner, for Long Term Evolution (LTE, LongTermEvolution) system, the situation that takies of physical resource also can be adopted to assess the resource utilization of LTE system.The physical carrier frequency resource of LTE system is split into multiple Resource Block according to time and frequency two dimensions, wherein control channel minimum resource allocation unit is control channel unit (CCE, ControlChannelElement), Traffic Channel minimum resource allocation unit is Physical Resource Block (PRB, PhysicalResourceBlock).Therefore, the wireless resource utility efficiency of LTE system can be considered in timing statistics, and during busy cells, control channel CCE occupancy and Traffic Channel PRB utilance are assessed.
At present for GSM and TD-SCDMA system, wireless resource utility efficiency is its System Expansion of assessment or the important references index subtracting appearance, and such as busy wireless resource utility efficiency is greater than certain thresholding, then need carrier frequency dilatation.For the dilatation appraisal procedure of this above-mentioned wireless communication system utilance of GSM and TD-SCDMA, effective when exclusive physical resource is taken for each business, namely when each user communication service shared by Radio Resource start just to be assigned with in business and carry out in business keeping in process always, adopt the situation that takies of physical resource can reflect the utilance of wireless communication system.This is because the distributive property of dedicated resources makes this physical resource can not by other CUs in the communication process of user, even if this user does not have data to send sometimes in communication process, physical resource still for this user retain be considered as occupied, therefore Radio Resource to take situation clearer and more definite.
But along with the introducing of shared channel resources, the above-mentioned situation for user's distributing radio resource there occurs change.From the high-speed slender body theory (HSDPA of 3G, HighSpeedDownlinkPacketAccess) start, until LTE, the physical resource of system is no longer exclusively distribute to some users, but the data that network side considers user send demand, the priority of business, the channel quality etc. of user, are dispatched by physical resource in real time to the user needed.Therefore, when subscriber traffic is large, network side may distribute more Radio Resource to user; And when subscriber traffic hour, network side then can distribute less Radio Resource to user.Such allocation of radio resources mechanism method of salary distribution that is relative and DCH is more reasonable, but such phenomenon can be produced: when user is little, the user of a high traffic may take all physical resources on this community or carrier frequency, and this situation can often exist in HSPA network and LTE network.Under this scene, if still adopt the occupied situation of physical resource to carry out the utilance of critic network, then can produce: when user is little, the result that wireless resource utility efficiency is still very large.Now, if still adopt physical resource utilance to subtract appearance to instruct the expansion of network, be obviously improper or even incorrect.

In addition, based on the number of users measured and user capacity thresholding, can also determine the size of dilatation, namely dilatation is to how many carrier frequency.
Suppose, the number of users of measurement is A
ii represents the number of samples of measurement, i=1,2 ..., the time long correlation of i and measurement, the user capacity thresholding that single carrier frequency is corresponding is N, the number that the number of users measured is greater than user capacity thresholding is x, or the accounting thresholding that number of users is greater than user capacity thresholding is k%, so pre-dilatation to carrier frequency number M be:
Mode 1:
or

represent the number that rounds up,
represent and get average, max (A
i) represent and get maximum;
Mode 2: the number increasing M one by one, in the number of users that as if statistics is measured, the number that the number of users of measurement is greater than M × N is less than x, then determine that carrier frequency number is M,
Mode 3: the number increasing M one by one, in the number of users that as if statistics is measured, the accounting that the number of users of measurement is greater than M × N is less than k%, then determine that carrier frequency number is M,
In the embodiment of the present invention, about how to add up or to measure number of users, and how to determine the thresholding of user capacity.Undertaken adding up or measuring by following several mode.
Statistics or measurement number of users: usually adopt RRC connection number of users to be used as the number of users of existing network statistics or measurement.
Connect number of users: can refer to that RRC connects number of users (maximum or mean value) or refers to that effective RRC connects number of users (maximum or mean value).Here can, for the statistics in statistics duration, also can be the result effectively transmitted in duration.
Effective RRC connects number of users and refers to have the RRC of transfer of data to connect maximum number or average.Be the cycle with 100ms, record effective RRC linking number, and get maximum number or the mean value in each cycle.Within every 100ms, if any one E-RAB (EvolvedRadioAccessBearer, evolution RAB) that certain RRC is correlated with has transfer of data, then it is effective for connecting depending on this RRC.
