Description
Technical field
The present invention relates to the capacity-enlargement technology of the communications field, particularly relate to a kind of dilatation parameter determination method and device.
Background technology
Along with TD SDMA (Time Division-Synchronous Code Division Multiple
Access, TD-SCDMA) lifting of covering quality of network and the market of TD-SCDMA terminal popularizes,
Number of users and the telephone traffic of TD-SCDMA all increase at high speed.The carrier configuration at networking initial stage is the most not
Can meet the demand of existing network user, website cell telephone traffic is congested more and more frequent, has a strong impact on the key of network
Performance indicators (Key Performance Indicator, KPI) and user's perception wellness.
What the most a lot of places were done is all dilatation afterwards (i.e. carrying out dilatation again after generation is congested), neither one
The most pre-dilatation scheme, because dilatation has a delayed time difference afterwards.So gathering around
Persistent period caused traffic, the economic loss of data filled in are very big, and can have a strong impact on user's use
Perception.
At present TD-SCDMA carrier frequency dilatation works increasingly normalization, particularly colleges and universities the new term begins, great
When festivals or holidays and movable guarantee, the accuracy of dilatation solution formulation is even more important.But dilatation scheme accurately
Formulate and be built upon accurately on the basis of business model, owing to the use habit of zones of different user is different,
Under different business models, TD-SCDMAS network generation dilatation demand differs greatly.And TD-SCDMAS
Business model is constantly in change at a high speed, and traditional method is difficult to determine accurate traffic model, and traffic
Model is difficult to transplant, and existing dilatation instrument is based on fixing business model, also results in traditional
Dilatation instrument is not suitable for new business model, it is impossible to calculate dilatation scheme accurately.
The most general dilatation parameter determination method is generally:
In the panel region (such as some colleges and universities) specified, statistics peak hour (such as 22:00-23:00)
Number of users, produce telephone traffic/data traffic, obtaining single user peak hour can produce how many telephone traffics and data
Flow, is multiplied by overall telephone traffic and data in amount (original subscriber's number+number of users of distributing telephone numbers) obtains this region
Flow.
Then estimate according to the empirical value of network optimization engineer, telephone traffic that single carrier can carry and data
Flow, required R4 carrier number=anticipated busy telephone traffic/single carrier can traffic carried, required H
Carrier number=anticipated busy data traffic/single carrier can carry data traffic.Calculate required R4/H carrier wave
After number, deduct existing R4/H carrier number and can get final dilatation parameter.
The problem that above-mentioned dilatation parameter determination method exists includes:
1, business peak hour is chosen unreasonable: as a example by colleges and universities, teaching area, library, dormitory area,
Business summit that the zones of different such as dining room occurs also differs, and business tidal effect is obvious, than
As higher in 8-12:00 class period section teaching building portfolio but dormitory is relatively low, and evening, 9:00 was with junior scholar
The raw higher teaching building of dormitory portfolio is relatively low, and the business peak hour of each community is different, but existing method is adopted
And do not conform to as the way of peak hour (being typically chosen 22:00-23:00) with unified certain time point of the whole network
Reason.
2, different districts business model is not treated with a certain discrimination: the use habit of user incomplete phase under different districts
With, such as A community user uses the OTT class business such as QQ, wechat, microblogging more, and B community user
Use HTTP web page browsing, Taobao, video class business more, so taking same code under A, B community
In the case of resource, the data traffic that B community produces is far longer than A community.That is A, B community
Business model difference relatively big, but according to prior art, all carriers carry data traffics, telephone traffic
For definite value, not differentiating between business model and calculate, result of calculation can cause differing greatly with existing network practical situation.
3, result of calculation can not be accurate to cell-level: final dilatation scheme is to need to implement to cell-level to come real
Execute, need to accurately calculate R4, H carrier number of each cell capacity-enlarging, but prior art to be both for certain a piece of
Region overall calculation, such as some colleges and universities' entirety need the carrier number of dilatation, but each community needs dilatation
R4, H carrier number cannot continue calculate, cause dilatation scheme the most accurate.
4, portable and sustainability is poor: along with number of users be continually changing, being continually changing of service package,
The change of user's use habit so that the business model of community is constantly in being continually changing, the most not
Becoming, prior art cannot accurately calculate business model, more cannot accomplish that service model self-adapting changes,
Affect business model accuracy and can continuity.
5, process is calculated loaded down with trivial details, inefficiency: existing computational methods, screen cell business volume, take code money
Source, existing network configuration carrier number, H carrier wave configuration high-speed physical down link sharing channel (High-Speed
Physical Downlink Shared Channel, HS-SCCH) data such as number need manually statistics to fill in, whole
Individual data calculation process is required to manual calculations, wastes time and energy and easily makes mistakes.

Below in conjunction with technique scheme, a kind of base station being applied to TD-SCDMA network presented below
The determination of dilatation parameter.
TD-SCDMA network traffic up-downgoing is fixing takies 2 BRU, so telephone traffic and shared BRU
It is directly proportional.Data traffic is the most different, and HSDPA carrier wave (HSDPA carrier wave can be called for short H carrier wave) is descending
Continuous three time slot configuration are HS-PDSCH channel, carry user face downlink data with the form of resource pool,
If carrier wave be configured with N to HS-SCCH channel (existing network typically configure two to or a pair), then synchronization is altogether
Having N number of user averagely to take this carrier resource pond, the descending BRU of taking of all users is identical simultaneously,
Without distributing different resource according to type of service.
Owing under different districts, user uses the custom of business different, under such as A community user use QQ,
The small-flow services such as wechat are more, and under B community, user uses that to browse the business such as webpage, brush microblogging more, by
The code utilization of resources in the case of the difference of the business of use, the data traffic that A, B Liang Ge community generation is same
Rate difference can be very big, in order to obtain accurately dilatation parameter, need accurately to calculate the two cell business volume and
Corresponding relation between BRU.
The configuration of yard resource is carried out in specifying community；The code resource configured carries out a yard resource occupation.
As it is shown on figure 3, the configuration of usual code resource can be described as again configuration code resource.Configuration code resource includes that configuration is every
The BRU quantity that one carrier wave is corresponding.
Taking of code resource, takies including business and controls channel occupancy.Business takies and can be divided into circuit domain
Exchange CS takies and packet switch takies PS business and takies.CS herein takies and i.e. may correspond to telephone traffic
Taking, described PS business takies and i.e. may correspond to above-mentioned data traffic and take.
Controlling channel occupancy can be divided into main carrier configuration control channel occupancy and H carrier wave configuration control channel to account for
With.
Configuration code resource: cell configuration auxiliary carrier wave TS0 is not typically available, so 1 carrier wave generally carries out letter
The time slot of breath transmission has six available time slot, and each time slot has 16 can be provided that 6 BRU.Main carrier
Upper 1st time slot TS0 can use.The BUR quantity of the information that the can be used for transmission of cell configuration can be according to as follows
Formula calculates: the BRU number of the configuration=each carrier wave of cell carrier number * available time slot each time slot of *
The number of the TS0 of available BRU number+main carrier.The most in the present embodiment, the BRU number of configuration=
Cell carrier number * 6*6+16.
Take a yard resource: being divided into business take yard resource and control channel occupancy code resource, it is main for controlling channel
The control channel of carrier wave and the control channel of H carrier wave.The control channel of main carrier include PCCPCH,
SCCPCH, FPACH, PICH and PRACH channel, HS-SICH and HS-SCCH of H carrier wave configuration
Channel, HS-SICH and HS-SCCH is to be organized in pairs, and up-downgoing takies 2 BRU, different loads respectively
The control channel logarithm of the H carrier wave of ripple is different, and possible configuration a pair or two is right.The control of all cell configuration
Channel BRU quantity reads from existing network configuration file (MML).
Traffic Channel takies a yard resource: what Traffic Channel took BRU number=total takies BRU number-control channel
Taking BRU number, Traffic Channel takies BRU and is divided into again CS business to take taking, wherein with PS business
CS business is up-downgoing symmetrical service, and telephone traffic takies BRU number and is directly proportional and (ignores and take BRU number to it
The little deviation of measurement period), so CS business is taken BRU number and can be calculated by this equation:
CS business is up to be taken=and CS business is descending takies BRU number=telephone traffic * N；Wherein, described N is
The BRU number that each traffic upstream or downstream of traffic take.The most described N can be 2.
Can show that the PS business of each community takies the BRU for uplink of BRU number=appointment community
Number CR.MeanNbrAssnBruDl+ specifies the BRU number for downlink transfer of community
CR.MeanNbrAssnBruUl-main carrier controls channel occupancy BRU number-H carrier Control channel occupancy BRU
Number (HS-SCCH logarithm * 4)-this cell telephone traffic takies BRU number.
Understand described main carrier to control channel occupancy BRU number can be 12 by statistics in the present embodiment；Institute
Stating H carrier channel and take BRU number can be HS-SCCH logarithm * 4.Wherein 4 for described in every a pair
HS-SCCH takies BRU number.
Described HS-SCCH logarithm is that this community all H carrier wave is configured with how many couples of HS-SCCH altogether.
Can get, by above formula, the BRU number that under different districts, PS business takies, further we
This cell data flow and the corresponding relation taking between BRU can be obtained.
Flow (the MB)/data traffic in the every BRU in this community carrying data traffic=this cell group territory takies
BRU。
After being calculated the every BRU in all communities carrying data traffic, can get each community by below scheme
R4, H number of carrier wave of required dilatation.According to specifying in community on configured R4 carrier wave and H carrier wave
BRU number, determine the BRU number needing dilatation, then according to the relation between carrier wave and BRU quantity,
Determine and need how many R4 carrier waves of dilatation and H carrier wave.
After obtaining the data traffic that the every BRU in each community can carry, can be according to terminal quantity, service package
Alteration calculates the number of users in a region and single user peak hour portfolio, and then obtains each community
The telephone traffic of peak hour, data traffic.R4, H carrier number required for the peak hour of community can be according to following
Formula calculates:
Required R4 carrier number=peak hour telephone traffic * is estimated number growth ratio * and is estimated single user traffic growth ratio
Example * 4/ ((16*6) * (0.6*0.75))
Required HS carrier number=peak hour data traffic * is estimated number growth ratio * and is estimated the increasing of single user data stream
Data traffic/((16*6) * (0.6*0.75)) of long ratio/every BRU carrying
Described peak hour data traffic * is estimated number growth ratio * and is estimated single user data stream growth ratio/every
The data traffic of BRU carrying, under the business model of this community, estimating peak hour data traffic needs how many
BRU carries.Denominator is the BRU reasonable value that single carrier can be provided by, be equally according to divided by 0.75 it
The utilization rate of rear 60% calculates.
