Background technology

Since the recent two decades, the development of the cellular mobile communication technology of multiple technologies standard is rapid, and various standards all have conventional capacity planning and the expansion planning method of oneself.

Conventional method for planning capacity generally is based on telecom operators' requirement, and the user behavior parameter is generally default value, empirical value or macroscopic statistics value with calling switching proportion value; The configuration of sub-district keystone resources normally is configured by the whole network standard value, mean value.Expansion planning can be divided into two levels usually: the first is based on big regional (certain administrative area in certain city or city); This zone of unified budget needs newly-increased contained fan scale; It two is particular geographic location of confirming that newly-increased scale is implemented, generally is according to radio network planning network optimization experience, preestablishes the threshold criterion of some definite cell-overload; In case the actual traffic in certain sub-district meets wherein one or more criterion, then list dilatation sub-district object in.To CDMA (Code Division Multiple Access, code division multiple access) system, the usual way of dilatation is to increase to authorize CE (Customer Edge, user network boundary device) quantity, or expands contained fan.

Though it is simple and convenient that above method uses, shortcoming is also clearly, and is specific as follows:

1, adopt the whole network mean value or empirical value that parameters such as user behavior parameter, soft-switch proportion are set, often the network actual conditions with particular geographic location have than mistake; As shown in Figure 1; Service area in a city; Multiple society and geographical function division are arranged, and traffic behavior (containing telephone traffic, the uplink downlink speed etc.) characteristic in these subregions is different usually, and the network topology layout of each subregion, user geographical position characteristics also have difference; Integrate, the telephone traffic characteristic of each subregion, actual capacity bearing capacity possibly differ greatly.

2, the analysis of dilatation and judgement are simple relatively; The load condition that does not have analysis-by-synthesis existing network different resource; The resource bottleneck that does not spell out existing network where, whether the bottleneck of network zones of different different, different bottleneck types; Whether expansion method is identical; The keystone resources of cdma wireless sub-district mainly comprises maximum activation number of users (or the equivalent user number) restriction of the preceding uplink throughput of eating dishes without rice or wine, mandate CE quantity, down transmitting power, OMC (Operations Maintenance Center operation maintenance center) configuration etc., and different resources is crossed the different adjustment mode that is loaded with, and just considers increase contained fan quantity in limited time when resource reaches.

When 3, selecting dilatation sub-district object, do not take all factors into consideration the load of existing network and the target scale that the user increases newly, formulate the dilatation scale of sub-district, the newly-increased back of user.

4, during expansion planning, the newly-increased scale of user does not carry out that geographical distribution is uneven to be handled, maybe be bigger with the error of objective circumstances.

As a whole, traditional, conventional expansion planning method belongs to extensive method, and also there is big distance in the target of planning with becoming more meticulous.Along with the raising that the user requires network service quality, telecom operators need meticulousr, more comprehensive expansion planning analytical method to the concern of input-output ratio, operation benefits.

Embodiment

In order to solve the extensive offending problem of prior art subregion dilatation, the invention provides a kind of subregion expansion method and device of cell communication network, below in conjunction with accompanying drawing and embodiment, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, does not limit the present invention.

As shown in Figure 2, the embodiment of the invention relates to a kind of subregion expansion method of cell communication network, comprising:

Step S101 carries out geographical zone in the goal programming scope, make the user behavior parameter when each base station cell traffic is busy in the subregion identical in error range, and the traffic of each base station cell is identical when busy;

In this step, the user behavior parameter the when traffic of each sub-district behind the subregion is busy is identical in error range, is appreciated that each base station cell user behavior parameter basically identical or more approaching when traffic is busy into subregion inside.Error can be provided with and change.Average every user activation connected duration, the average downstream rate of active link, the average upstream rate of active link when wherein, the user behavior parameter mainly referred to hurry.Traffic is meant when busy: in one day 24 hours, the cell call telephone traffic is the highest one hour.The traffic of each base station cell is identical when busy, also is meant, the traffic of each base station cell is identical in error range when busy, is not the identical of absolute sense.When for example, the traffic of certain sub-district is busy is 21:00～22:00; The traffic of another one sub-district is 20:00～21:00 when busy, but the call traffic of this sub-district 21:00～22:00 is 83% of 20:00～21:00 call traffic also than higher; The error of setting be peak hour call traffic 80%～100%, then these two sub-districts can think that traffic is identical when busy, at 21:00～22:00.Need enlarge the data service userbase with certain colleges and universities' zone C DMA2000 1x network below is example, divides teaching district, dormitory area and mixed zone in the school, carries out the expansion planning analysis respectively.Professional and the speech business difference allocation carriers of this area data, two kinds of business are independent of each other, and can solely analyze the data business sheet easily, and hereinafter is only discussed data business content.To the zone of other types, for example economic development zone, central business district etc., operation gets final product with reference to same thread; To the CDMA20001xEV-DO network, it is also similar that it analyzes thinking, is that concrete system parameters is different.

Step S102 according to the configuration data and the traffic data of existing network resource, judges the bottleneck of sub-district.

According to actual conditions, obtain existing network resource distribution data and important traffic data respectively.Wherein, existing network resource distribution data comprise: existing number of cells, number of carriers, mandate CE quantity, radio configuration (RC, Rradio Configuration) value, descending power Configuration Values.The configuration data of existing network resource, concrete resource is relevant with system type, and for example the CDMA20001x system mainly comprises: Traffic Channel CE authorized quantity, Walsh number of codes, the throughput of eating dishes without rice or wine, descending power etc.; The CDMA20001xEV-DO system mainly comprises: Traffic Channel CE authorized quantity, MacIndex quantity, the throughput of eating dishes without rice or wine, excited user number thresholding etc.Important traffic data all refers to the busy-hour statistics value, comprising: existing network is distributed telephone numbers or active users, each cell call telephone traffic, soft handover telephone traffic, More Soft Handoff telephone traffic, subregion down link data total flow, subregion uplink data total flow, the descending Mean Speed of active link, the up Mean Speed of active link.Above data can obtain through configuration record, data statistics or the inspection of existing network.

Then,, fill in the projecting parameter input, represent dilatation target, system bearing ability, fill in by the developing goal requirement according to the requirement of telecommunication network operators.Comprise: the scale that Adds User, communication service levels (GOS; Grade of Service; Also claim blocking rate), dilatation load thresholding (be also referred to as the target resource utilance, default value is 70%), forward power load thresholding, sub-district can carry maximum downstream throughput, sub-district and can carry that maximum uplink throughput, radio configuration (RC) are selected, average every contained fan increases the CE authorized quantity.

Concrete, in this step, need to calculate following 7 kinds of parameters:

1, " soft, More Soft Handoff ratio ", computing formula is: this subregion is should business soft, the ratio of More Soft Handoff telephone traffic and call traffic;

2, " descending SCH (Supplemental Channel; Supplemental Channel) takies the CE ratio "; Computing formula is: descending SCH takies CE duration and FCH (frequency correction channel: Frequency Correction Channel; Be called for short FCH) take the ratio of duration, to 6700 channel boards commonly used now;

3, " descending SCH takies Walsh sign indicating number ratio ", computing formula is: (descending SCH takies Walsh sign indicating number duration * speed multiple) and FCH take the ratio of duration;

4, " existing network resource utilization ", computing formula is: existing network telephone traffic/(but existing network contained fan number * every contained fan traffic carried);

5, " descending, uplink throughput limits to a number or amount "; The computing formula of down link is: contained fan maximum downstream throughput/active link Mean Speed/(1+ switching proportion); Notice that descending complement channel do not participate in soft handover, and the complement channel of up link is participated in soft handover;

6, " average every contained fan CE limits to a number or amount ", computing formula is: (average every contained fan CE can use number+average every contained fan to increase the CE authorized quantity)/(1+ soft-switch proportion+descending SCH takies the CE ratio);

7, " the Walsh sign indicating number limits to a number or amount ", computing formula is: the Walsh that RC is corresponding can use number/(1+ soft-switch proportion+More Soft Handoff ratio+descending SCH takies Walsh sign indicating number ratio); The available number of RC3 is 61, and the available number of RC4 is 122.

In the aforementioned calculation, need existing network user behavior parameter, existing network user behavior parameter comprises:

1) " descending, the up Mean Speed of active link "; Computing formula is: subregion downlink or uplink physical layer flow * 8/ (call traffic+soft handover telephone traffic+More Soft Handoff telephone traffic)/3600/1000;

2) " user's average data telephone traffic when hurrying ", computing formula is: subregion call traffic/1x data service number of users.

At last, contrast the clean effectively quantity that above-mentioned 7 kinds of keystone resourceses can carry the user activation link, a kind of resource that the peek amount is minimum is denoted as " bottleneck " of this subregion or sub-district; Clean effectively quantity is meant, rejects after soft handover redundancy and the More Soft Handoff redundancy, but various resource bearing activation number of links.

The final traffic bearing capacity of bottleneck decision subregion or sub-district.Wherein, this subregion or sub-district present situation resource utilization equal present situation when busy telephone traffic (be designated as T _Cur) (be designated as T divided by the traffic bearing capacity _Bear).

Step S103 judges whether said bottleneck can expand, if then change step S104; If, then do not change step S105.

To bottleneck, perhaps can expand in the sub-district, perhaps can not expand again in the sub-district; If bottleneck is can expand in the sub-district; Can allocate by Virtual network operator (optional); Purpose is to make the type no longer become bottleneck, can improve the traffic bearing capacity of sub-district like this, and the present situation resource utilization of subregion or sub-district will change behind the resource allocation.

In this step, be example,, maybe not need expand contained fan if following two kinds of bottlenecks then have the leeway (in the projecting parameter input step) of allocating allocated resource with cdma2000 1x system; If be other bottleneck, then need expand contained fan quantity.

1), bottleneck is CE (channel) resource;

2), bottleneck is " a Walsh sign indicating number resource ".

Step S104 to said bottleneck allotment, changes step S102 then.

For bottleneck is CE (channel) resource, then increases the CE authorized quantity; For bottleneck is " Walsh sign indicating number resource ", need check that then " the RC selection " of existing network is RC3 or RC4, if be RC3, then can change RC4 into, works to expand Walsh sign indicating number resource.

In this step, owing to after the bottleneck that step S101 the judges expansion, cause parameter to change, original bottleneck possibly no longer be a bottleneck, therefore, need look for the bottleneck that rejudges the sub-district.

Step S105, the contained fan quantity of dilatation sub-district.

Setting needs newly-increased userbase, target resource utilance.Can the dilatation userbase be set by the mode unification of the whole network and the target resource utilance (is designated as U _Obj, promptly need the load recognitiion gate limit for tonnage of dilatation sub-district), also can be provided with respectively by the per minute district.The mode of the whole network is unified to be provided with if press, and then the dilatation userbase is assigned to the default method of each subregion, is the weight allocation by the per minute district, and the per minute district accounts for the weight of the whole network, equals the ratio that existing network per minute district telephone traffic accounts for the whole network telephone traffic.

Can also can the traffic growth ratio be set respectively by the unified traffic growth ratio that is provided with in the subregion by each sub-district in the subregion; If press unified set-up mode in the subregion, think that then the traffic increasing degree of each sub-district is identical, equal the subregion scale that Adds User and (be designated as N _Inc) (be designated as N divided by the present situation userbase _Cur).

In this step, need obtain the descending power dimension respectively needs dilatation contained fan quantity and conventional resource to need dilatation contained fan quantity; Taking off capable power dimension needs dilatation contained fan quantity and conventional resource to need higher value in the dilatation contained fan quantity as the contained fan quantity of sub-district.

For the dilatation of descending power dimension, need to judge whether descending power transships behind the newly-increased capacity, that is: behind the capacity that Adds User; Telephone traffic must rise; This parameter is approximate judgment value, surpasses the power load value of appointment if the descending power that newly-increased traffic causes rises, and being judged as needs dilatation; Otherwise, be judged as and need not dilatation.

Concrete judgment formula is formula (2):

(P-P _max×R _control)×(1+T _new/T _cur)＞P _max×(1-R _control)×R _t (2)

Formula (2) is set up then to be judged as needs dilatation, and formula (2) is false, and then is judged as and need not dilatation.Wherein, P is the average descending power of the every carrier wave of present situation, P _MaxBe the maximum power of every carrier wave configuration, R _ControlBe overhead channel power ratio, T _NewBe newly-increased telephone traffic, T _CurBe the average every contained fan telephone traffic in sub-district, R _tBe service channel power given load thresholding.

((P-P _max×R _control)×(1+T _new/T _cur)/(R _t×P _max×(1-R _control))-1)×C _cur (1)

Wherein, formula (1) the institute's value that rounds up is said descending power dimension and needs dilatation contained fan quantity, C _CurBe professional present situation number of carriers.

For conventional resource capacity expansion, need judge whether conventional resource needs dilatation according to formula (4).Wherein, conventional resource refers to except that descending power, considers that from other resource dimension (for example Walsh sign indicating number, CE, interface-free resources etc.) of system whether need dilatation, computing formula is:

Whether judgment formula (4) is set up,

$\frac{T_{\mathrm{cur}}\·(1+\frac{N_{\mathrm{inc}}}{N_{\mathrm{cur}}})}{T_{\mathrm{bear}}}>U_{\mathrm{obj}}---\left(4\right)$

Wherein, C _CurBe professional present situation number of carriers, T _CurBe the average every contained fan telephone traffic in sub-district, N _IncBe the subregion scale that Adds User, N _CurBe present situation userbase, U _ObjFor needing the load recognitiion gate limit for tonnage of dilatation sub-district, T _BearThe telephone traffic that can carry for the sub-district.

Obtaining after the contained fan quantity of sub-district, to the dilatation scale of whole subregion, is adding up to each sub-district result; Can whether need dilatation to each sub-district in the subregion, need the judgement of what carrier frequency of dilatation, add up each sub-district required dilatation carrier frequency number at last, obtain the subregion carrier frequency number of required dilatation altogether.To the dilatation scale of the whole network, be adding up to each subregion result.

It should be noted that The above results is conservative requirement, wait other factors, finally need the scale of dilatation also possibly further increase if consider the unification of subregion intercarrier quantity configuration requirement.
