The embodiment of the present invention one proposes a kind of network capacity extension method, as shown in Fig. 2 its concrete handling process is such as Following：

Step 20, the first user that prestores perceives the of rate threshold and first network dilatation criteria thresholds One corresponding relation.

Wherein it is possible to obtain first user perception rate threshold and first network dilatation index in the entire network First corresponding relation of thresholding.Can also network in a more wide region, obtain first user Perception rate threshold and the first corresponding relation of first network dilatation criteria thresholds.

Under normal conditions, when dilatation being carried out to cell, general only consideration network capacity extension index, wherein, In standard it is stipulated that：

Correspondingly, in network capacity extension index, the formulation mode of each criteria thresholds is as follows：

The formulation mode of network utilization thresholding：To ask for determining channel utilization thresholding according to Network Programe Design. (K value implication in definition：Consider that in the network planning up till now, system internal interference level controls requirement, introduce K Value is to determine system stability available resources.Network planning index is to formulate under the load of adjacent area 50% at present, because This preliminary advice value is K=0.5.Then as K=0.5, utilization rate dilatation thresholding is 100%, if K=1, Then network utilization dilatation thresholding is 50%).

Effectively RRC connects number of users thresholding：Take and determine business model, Binding experiment room LTE equipment effectively holds Loading capability test determines that the RRC having data transfer connects number thresholding, the such as number of users and little according to test The relation of area's speed, takes under the requirement of cell edge 1Mbps when determining the network planning, and number of users is 30 works For thresholding.

Traffic threshold：The cell speed of foundation channel utilization thresholding (50%, K=1) and actual measurement is (for example Average 22Mbps) calculate take determine busy cell flow thresholding (up 1GBytes, descending 5GBytes).

Above-mentioned only considered the network capacity extension criteria thresholds when under normal circumstances dilatation being carried out to cell, but It is that this kind of mode fails to consider user's perception, in the technical scheme that therefore embodiment of the present invention one proposes, permissible At least one in the following manner obtains described first corresponding relation：

First kind of way：Based on statistic algorithm, the user's perception speed in network and network capacity extension index are entered Row statistics, the user meeting setting network dilatation condition is perceived rate threshold is corresponding with network capacity extension index deposits Storage, as the first corresponding relation.

In this kind of mode, when being embodied as, can be required according to the network planning, to the user's perception in network Speed and network capacity extension criteria thresholds situation are counted, and according to dilatation scale plan overall in network, determine User's perception speed, total thresholding of network capacity extension criteria thresholds, thus obtain the first corresponding relation.

To be described in detail with an example：

First, count user's perception rate index of each cell of the whole network and the numerical value of network utilization index, have Effect RRC connects the numerical value of number of users index, the numerical value of cell flow index.

Secondly, according to statistical result, as shown in Fig. 3 a～Fig. 3 d, feel according to different users to obtaining data Know to be classified in the interval of speed, such as, shown in table 1, the cell according to every class carries out cumulative distribution function (English Literary composition：Cumulative distribution function, abbreviation：CDF) curve plotting, advises according to the whole network dilatation Mould plan x% (such as 5%) is 1-x% (such as 95%) as probability benchmark, to obtain the door of each index Limit value, forms dilatation assessment reference table (as a example the descending transmission channel of table 1) based on client perception. Wherein, x%=5%.Or directly obtain this table according to other modeling demands etc., such as 95%～100% is set to Confidence interval, obtains each criteria thresholds value on CDF curve on the basis of 95%.

In above-mentioned table 1, only provide a kind of signal, not preferred forms, related data needs further Enrich and improve curve and the threshold value of response.Network utilization thresholding takes based on perception thresholding and working standard Thresholding 50% (K=1) minima.

When determining dilatation index, need to consider control channel impact, consider that up-downgoing situation is different simultaneously, Uplink/downlink network utilization is separately defined.Correspondingly, up corresponding reference table can also be obtained.Such as table (reference table example, up, x%=5% are assessed in the dilatation based on client perception) shown in 2.Different x% can obtain Obtain different reference tables, reference table can periodically update according to network Development situation, user perceives rate requirement Scope can be self-defined according to demand.

Table 2

Wherein, taking LTE network as a example, network utilization is defined as follows：

Under normal circumstances, define LTE network utilization rate=MAX { busy up PUSCH PRB utilization rate； Busy descending PDSCH PRB utilization rate；Busy descending PDCCH CCE utilization rate }.

In the technical scheme that the embodiment of the present invention one proposes, LTE uplink network utilization rate=MAX is { in busy Row PUSCH PRB utilization rate；Busy PDCCH CCE utilization rate }.

LTE downlink network utilization rate=MAX { busy descending PUSC H PRB utilization rate；Busy PDCCH CCE utilization rate }.

Wherein：Busy up PUSCH PRB utilization rate=busy up PUSCH PRB occupancy average/ (busy up PUSCH PRB can use average × K).

User's perception rate index can be divided into：

User's descending perception speed=downlink user Mean Speed=community user face descending byte number * 8/ cell PDCP layer sends the business total duration of downlink data.

User uplink perceives speed=uplink user Mean Speed=community user face up byte number * 8/ cell PDCP layer sends the business total duration of upstream data.

Wherein, for the determination of x%, the embodiment of the present invention also provides a kind of determination method here：

Multiple dilatations based on client perception speed can be given and assess reference table according to said method 1,2 ..., n, correspond to expansion planning x1%, x2% ..., xn% respectively, are then issued to different regions, then Each areas case, carries out cell carrier frequencies dilatation assessment, obtains its this cell capacity-enlarging scale, to waiting in region to expand The dilatation scale holding region is integrated, and according to investment situation or market situation, or other expansion planning feelings Condition, determines dilatation scale plan, that is, determine x%.

The second way：To cell each in network, respectively each cell is carried out with single operational trials, obtain user Perception rate threshold, and according to the user's perception rate threshold obtaining, obtain and meet user's perception speed door The network capacity extension criteria thresholds of limit, user are perceived rate threshold and meet the network that user perceives rate threshold The corresponding storage of dilatation criteria thresholds, as the first corresponding relation.

It is described in detail with an example：

Rate requirement is perceived according to user, for example, opens certain service delay and require as z second (such as 3s～5s), Then this user perception requirement is mapped to network requirement is pMbps～qMbps, in the case of this kind, can pass through Following manner determines network capacity extension criteria thresholds：

Step 22, determines region active user perception speed to be assessed and current network dilatation index.

Step 23, compares in active user's perception speed and current network dilatation index and the second corresponding relation Second user perception rate threshold and the second network capacity extension criteria thresholds.

Step 24, judges whether comparative result meets cell capacity-enlarging condition.If it is judged that when being, execution Step 25, conversely, end is processed.

Judge whether comparative result meets cell capacity-enlarging condition, can include：

For each cell in region to be assessed however, it is determined that go out cell current network dilatation index be more than or When being equal to or more than equal to the second network capacity extension criteria thresholds in the second corresponding relation, determine this comparative result Meet cell capacity-enlarging condition.

It is less than however, it is determined that going out described cell active user perception speed for each cell in region to be assessed Or be equal to or when cell is equal to the second user perception rate threshold in the second corresponding relation, and current dilatation When criteria thresholds are more than or equal to or are more than or equal to the second network capacity extension criteria thresholds, determine that comparative result meets Cell capacity-enlarging condition.

Step 25, when the comparative result obtaining meets cell capacity-enlarging condition, enters to the cell of pending dilatation Row carrier frequency dilatation.

Alternatively, after above-mentioned steps 24, can also include：

Count user's perception speed and the network capacity extension index in the setting cycle of each cell；

If in setting cycle, active user perceives speed and the meansigma methodss of network capacity extension index meet dilatation bar During part, then carrier frequency dilatation is carried out to cell preference other cell.

In this kind of mode, the active user of cell perceives the meansigma methodss of speed and the meansigma methodss of network capacity extension index, Can be in setting cycle, cell perceives meansigma methodss and the network of speed from the active user of this cell of busy The meansigma methodss of dilatation index.Can also be in setting cycle, cell at the appointed time section when this cell work as Front user's perception meansigma methodss of speed and the meansigma methodss of network capacity extension index.

If in setting cycle, user perceives speed and the meansigma methodss of network capacity extension index do not meet dilatation condition, And the user of cell perceives speed and the meansigma methodss of network capacity extension index meet dilatation in the first setting duration During condition, according to scene, carrier frequency dilatation assessment is carried out to cell.

Wherein, first set duration less than setting cycle.

If in setting cycle, the user of cell perceives speed and the meansigma methodss of network capacity extension index do not meet expansion Appearance condition, and the user of cell perceives speed and the meansigma methodss value of network capacity extension index sets in duration second When meeting dilatation condition, to cell monitoring.

Wherein second sets duration is less than described setting cycle.

Set certain region downlink user perception rate threshold (i.e. second downlink user sense in the second corresponding relation Know rate threshold) it is 5Mbps.To be described in detail with an example:

First, for each cell in region to be assessed, arbitrary cell pair in each cell determined The active user's perception speed answered and current network dilatation index.

Secondly, in the second corresponding relation prestoring, obtain second user perception rate threshold corresponding Second network capacity extension criteria thresholds.

For example, according to table 3, the corresponding downlink network utilization rate of descending 5Mbps is 58%, user Number 11, during descending busy cells, flow is 3GB.

Then, active user's perception speed of each cell of region to be assessed, current network dilatation index are counted Each indexs such as (network utilization, number of users, flows), is compared with the second network capacity extension criteria thresholds, Carry out cell capacity-enlarging assessment.

When carrying out dilatation assessment, can be using any in following two ways：

First kind of way：For each cell in region to be assessed however, it is determined that going out cell active user perception When speed is less than or equal to or cell is equal to the second user perception rate threshold in the second corresponding relation, and work as When front dilatation criteria thresholds are more than or equal to or are more than or equal to the second network capacity extension criteria thresholds, determination is compared Result meets cell capacity-enlarging condition.

In this kind of mode, consider active user's perception rate requirement, current network dilatation index (utilizes Rate, number of users, flow) index.

I.e. in this kind of mode, first determine whether whether active user's perception speed of this cell is more than or equal to second User perceives rate threshold, if so, not dilatation；If it is not, investigating current network dilatation index further, when When front dilatation index is all higher than or is equal to the second network capacity extension thresholding, then carry out cell capacity-enlarging.

For example：Assume to be directed to region to be assessed, set second user perception rate threshold as 5Mbps；

By consulting the second corresponding relation prestoring, obtain the second network capacity extension criteria thresholds.

Wherein, if descending active user's perception speed of the network of cell to be assessed is more than or equal to 5Mbps, Not dilatation.If descending active user's perception speed of subzone network to be assessed is less than 5Mbps, sentence further Disconnected, if the network utilization utilization rate in the current network dilatation index of downlink network is more than or equal to 58% and has Effect RRC connects number of users and is more than or equal to 11, and descending cell flow is more than or equal to 3.0GB, then need Dilatation, or up current network dilatation index is all higher than thresholding, carries out cell capacity-enlarging, otherwise not dilatation.

The second way：For each cell in region to be assessed however, it is determined that the current network going out cell expands When appearance index is more than or equal to or is more than or equal to the second network capacity extension criteria thresholds in the second corresponding relation, really Determine comparative result and meet cell capacity-enlarging condition.

In this kind of mode, only consider based on the second network capacity extension criteria thresholds in the second corresponding relation.

In this kind of mode it is assumed that：For region to be assessed, according to the service conditions in this region, obtain descending The second user perception rate threshold of network is 5Mbps.

By consulting the second corresponding relation, obtain the second network capacity extension criteria thresholds.

If network utilization is more than or equal to 58% in the current network dilatation index of the downlink network of cell to be assessed And effectively RRC connects number of users and is more than or equal to 11, and descending cell flow is more than or equal to 3.0GB, then Need dilatation, or up dilatation index is all higher than thresholding, then carry out cell capacity-enlarging, otherwise not dilatation.

The each indicator-specific statisticss of above-mentioned judgement are it is proposed that put down from a days (such as one week 7 days) of busy based on cell Average is judged.Wherein the maximum busy of network utilization can be defined as from busy.If each index a Its average situation is satisfied by requiring then to carry out urgent capacity expansion, if average is unsatisfactory for requirement but has b days in a days Index meets requirement and then considers that branch scape dilatation (has 5 days satisfactions for such as 7 days, for colleges and universities, office building etc. The scene of daily schedule on working day related intimate can consider dilatation), if average is unsatisfactory for requiring in a days But have c days indexs to meet to require then to consider that emphasis supervises these cells, keep a close eye on change, or according to other Condition considers whether dilatation.

Said process can also form the early warning mechanism of cell capacity-enlarging, as shown in figure 4, in early warning mechanism, A kind of embodiment can include：

Average dilatation evaluation index meets requirement, urgent capacity expansion within one week.

One week average dilatation evaluation index is unsatisfactory for requiring, but has 5 days dilatation indexs to meet in 7 days and require, Consider the factors such as scene and carry out dilatation.

One week average dilatation evaluation index is unsatisfactory for requiring, but has 3 days dilatation indexs to meet in 7 days and require, Emphasis is supervised.
