Embodiment

The embodiment of the invention provides a kind of acceptance controlling method, system, base station controller.

In order to make those skilled in the art person understand the present invention program better, the embodiment of the invention is described in further detail below in conjunction with drawings and embodiments.

Below introduce first embodiment of acceptance controlling method of the present invention.Fig. 1 shows the flow chart of first embodiment of the invention, and as shown in Figure 1, this embodiment comprises:

S101: determine power resource and code channel resource that the system unit bit rate provides.

At low rate (LCR, Low Chip Rate) time division duplex (TDD, Time Division Duplex) (Code Division Multiple Access, CDMA) in the wireless system, the topmost factor of restriction system capacity comprises code channel and power in the code division multiple access access.Code channel is meant spreading code, if code channel is not enough, then the user can't realize spread spectrum.If power is not enough, then UE also can't insert.And, because the near-far interference of CDMA if the UE that inserts is too much, can cause transmitting power to increase, increase thereby disturb, influence the performance of system.

Therefore, at first determine power resource and the code channel resource that system provides here under the unit bit rate, i.e. power resource and the code channel resource that provides for access service under the unit bit rate.

Concrete, S101 can be realized by following two steps:

S1011: determine the resources occupation rate of power in the system and the resources occupation rate of code channel respectively.

The power that takies of access service can pass through Iub mouth (base station (NodeB) and radio network controller (Radio Network Controller, RNC) (Received Total Wideband Power RTWP) obtains the measuring amount interface between)-reception total bandwidth power.

Below provide a kind of account form of resources occupation rate (Utilization_ROT) of power, as obtaining by following formula:

$\mathrm{Utilization}\_\mathrm{ROT}=\frac{\mathrm{PTWP}/N0}{\mathrm{ROT}\_\mathrm{thrshold}}---\left(1\right)$

(1) in, RTWP is the measuring amount that NodeB reports, and N0 is the white Gaussian noise power spectral density.ROT_threshold is that RNC is the ROT thresholding of NodeB configuration.ROT is the ratio of sub-district received power and white Gaussian noise.General white Gaussian noise is a constant, so ROT reflected the threshold value of received power, thus indirect reflection the threshold value of disturbing.

ROT_threshold generally is a fixed value.The power of current access service takies situation and also can not embody by the form of passing through occupation proportion shown in the following formula, and by received bandwidth total power (Received Total Wideband Power, RTWP) directly reflection.

Code channel is a valuable source in the cdma system, is a limited factor of power system capacity, if all code channels are occupied always, promptly resource utilization reaches 100%, and then might to reach capacity saturated in system, can not insert new user again.

Code channel occupancy (Utilization VRU) can calculate by following formula:

$\mathrm{Utilization}\_\mathrm{VRU}=\frac{\underset{k=1}{\overset{K}{\mathrm{\Σ}}}\underset{j=1}{\overset{N}{\mathrm{\Σ}}}{\mathrm{VRU}}_{k,j}}{\underset{j=1}{\overset{N}{\mathrm{\Σ}}}{\mathrm{VRU}\_\mathrm{TTI}}_j}---\left(2\right)$

(2) K represents the sequence number of the terminal of connecting system, and j represents Transmission Time Interval (Transmission Time Interval, sequence number TTI), VRU _{K, j}Represent the empty code channel number that k UE takies in j TTI of timing statistics.A code channel can take a plurality of empty code channels, and (Spreading Factor SF) is 8 code channel, also can think to have taken two empty code channels to take a spreading factor as certain class business.When statistics is utilized resource, having adopted the notion of empty code channel here, is the resource units unanimity that takies for all kinds of business.In a word, utilize empty code channel to reflect code channel resource here.Can certainly reflect code channel resource by alternate manner as the case may be.And the N in the summation symbol represents that the total number of TTI in the timing statistics, K represent the UE total number that has inserted.Then

K UE having inserted of expression takies the summation of empty code channel in timing statistics separately.

(2) VRU_TTI in the formula _jRepresent the empty code channel number that Traffic Channel can take among j the TTI, N represents the total number of TTI in the timing statistics, then Represent all empty code channel numbers that can take in N the TTI.

Like this, (2) formula is represented the code channel occupancy of access service.(2) in the formula, divide the actual code channel resource that takies in the subrepresentation timing statistics, denominator is represented operable total code channel resource (comprising occupied and unappropriated) in the timing statistics.For example, timing statistics is 100 milliseconds, and per 5 milliseconds is a TTI, and each TTI has 64 empty code channels (concrete code channel number is relevant with the number of time slot that Traffic Channel takies), then the operable code channel number of timing statistics is 64*20=1280, and this value is denominator value.In these 100 milliseconds, be not that each TTI has the user to have data to send, therefore divide subrepresentation the actual code channel situation that takies, taken 1000 code channels as actual, then resource utilization is 1000/1280, is in 20 TTI the code channel occupancy of access service.

S1012: the bit rate that provides is provided.

Among the S1011,, can obtain the situation that takies of code channel and power by (1) and (2) formula.Take under the situation at such power and code channel, the bit rate that provides (Provided_Bit_Rate) can obtain by following formula:

$\mathrm{Provided}\_\mathrm{Bit}\_\mathrm{Rate}=\underset{i=1}{\overset{I}{\mathrm{\Σ}}}E\_\mathrm{DCH\; ProvidedBiteRateMeasurem}{\mathrm{ent}}_i---\left(3\right)$

Wherein, i represents the sequence number of mac-d stream.UE different in the system may carry out different business, as speech business, web page browsing etc.Different business belongs to different mac-d stream at high level when carrying out Data Receiving or sending, be exactly total this formula is wanted speed of all business that computing system can provide.E_DCH and E_DCHProvidedBiteRateMeasurement also introduce.E-DCH is the transmission channel of HSUPA, and E_DCHProvidedBiteRateMeasurement is the measuring amount of NodeB, statistics be in a period of time, the bit rate of E-DCH channel.

S1013: according to the resources occupation rate of power in the system and the resources occupation rate of code channel, and the bit rate that provides, determine power resource and code channel resource that the system unit bit rate provides.

By above-mentioned several amounts, the power resource that can obtain unit speed needs is:

$\frac{\mathrm{Utilization}\_\mathrm{ROT}}{\mathrm{Provided}\_\mathrm{Bit}\_\mathrm{Rate}}---\left(4\right)$

The code channel resource that unit speed needs is:

$\frac{\mathrm{Utilization}\_\mathrm{VRU}}{\mathrm{Provided}\_\mathrm{Bit}\_\mathrm{Rate}}---\left(5\right)$

(4), (5) two formulas have illustrated the resource that the unit bit rate provides.For example in (4) formula, Utilization_ROT is 80%, current 80% the power resource that taken in the expression system, and this moment, Provided_Bit_Rate was 100k, expression provides the speed of 100k, and then the resource of unit speed needs is that every k speed needs 80%/100k=0.8%.The principle of the code channel resource that the unit bit rate needs similarly.

S102: power resource that provides in the bit rate of the UE that inserts according to request and the described unit bit rate and code channel resource obtain the power and the code channel resource of the UE needs that described request inserts.

(4), power resource and code channel resource that the unit bit rate provides have been drawn in (5) two formulas.

If there is new UE to insert, the rate requirement of the UE that inserts as new request is 64k, and the power that unit speed (every K) provides is 0.8%, and the resource that then should the new UE of access needs is 0.8%*64k, obtains the power resource that needs.The power resource that the new UE of access needs is expressed as Needed_ROT_Resource here _New, the rate representation that newly inserts UE is UE_Rate _New, then can be as shown in the formula expression:

$\mathrm{Needed}\_\mathrm{ROT}\_\mathrm{Re}{\mathrm{source}}_{\mathrm{new}}=\mathrm{UE}\_{\mathrm{Rate}}_{\mathrm{new}}*\frac{\mathrm{Utilization}\_\mathrm{ROT}}{\mathrm{Provided}\_\mathrm{Bit}\_\mathrm{Rate}}---\left(6\right)$

The code channel resource that new UE needs is similar to the above, if the rate requirement of new UE is 64k, and the code channel that unit speed (every K) provides is 0.4%, and the resource that then should newly insert UE needs is 0.4%*64k.The code channel resource that the new UE of access needs is expressed as Needed_VRU_Resource here _New, newly insert UE speed such as before be expressed as UE_Rate _New, then can be as shown in the formula expression:

$\mathrm{Needed}\_\mathrm{VRU}\_\mathrm{Re}{\mathrm{source}}_{\mathrm{new}}=\mathrm{UE}\_R{\mathrm{ate}}_{\mathrm{new}}*\frac{\mathrm{Utilization}\_\mathrm{VRU}}{\mathrm{Provided}\_\mathrm{Bit}\_\mathrm{Rate}}---\left(7\right)$

Like this, in case there is new UE request to insert,, can calculate the power and the code channel resource that need according to the rate requirement of UE.

S103: power resource that the UE that inserts when the judgement described request needs and the power resource sum that has taken are less than total provided power resource, and code channel resource that the UE that the judgement described request inserts needs and the code channel resource sum that has taken allow the UE of described request access to insert less than total provided code channel resource.

The power resource that can provide in the system and the upper limit of code channel resource are generally all determined.For example a sub-district disposes according to it, and the power resource that can provide and the upper limit of code channel resource are generally all determined.

Concrete, can obtain system's available code channel and power resources at most according to Utilization_ROT and Utilization_VRU, for example available code channel and power resources at most in sub-district.Certainly, also can obtain system's available code channel and power resource at most by alternate manner.Here, system's available code channel resource at most is expressed as VRU_Total, and system's available power resource at most is expressed as ROT_Total.

System is before the UE that permits new request inserts, and there are a definite value respectively in power resource that provides and code channel resource.If the UE desired power resource sum that power resource that provides and new request insert is less than ROT_Total, and the needed code channel resource sum of UE that the code channel resource that provides and new request insert then has the ability to insert the UE of this new request less than VRU_Total in the illustrative system.

Like this, can insert the UE of new request according to following two condition criterion systems:

Needed_VRU_Resource _New+ VRU_Resource _Old＜VRU_Total condition 1

Needed_ROT_Resource _New+ ROT_Resource _Old＜ROT_Total condition 2

If the UE that i.e. request inserts can satisfy above-mentioned condition 1 and condition 2, the UE that then can allow this request to insert inserts.Otherwise, can refuse the access of this UE or do other processing.

Wherein, VRU_Resource _OldThe code channel resource that expression provides, ROT_Resource _OldThe power resource that expression provides.

The account form of a kind of code channel resource that provides and power resource below is provided:

$\mathrm{VRU}\_\mathrm{Re}{\mathrm{source}}_{\mathrm{old}}=1-\underset{i=1}{\overset{I}{\mathrm{\Σ}}}{\mathrm{GBR}}_i*\mathrm{Utilization}\_\mathrm{VRU}---\left(8\right)$

$\mathrm{ROT}\_\mathrm{Re}{\mathrm{source}}_{\mathrm{old}}=1-\underset{i=1}{\overset{I}{\mathrm{\Σ}}}{\mathrm{GBR}}_i*\mathrm{Utilization}\_\mathrm{ROT}---\left(9\right)$

Above in (8) and (9) formula, i is the sequence number of the mac-d stream that exists in the system, I represents the sum of mac-d stream.Guarantee bit rate (Granted Bite Rate, GBR) Ye Wu situation, the bit rate of GBR value for existing for guaranteeing; Whom for the situation that does not have the GBR business, can according to demand GBRi be made as (to set?) value or be made as 0.The implication of top formula be the user that inserted under the prerequisite that satisfies its QoS demand, the resource that need take.GBR is its rate requirement value.

By the foregoing description, can obtain under the current channel condition needed code channel resource of unit of transfer's bit information and power resource.Like this, in case when having new UE request to insert, can calculate according to the demand rate of this UE and insert needed code channel resource and power resource, all not reach under the situation of system's upper limit with code channel resource that provides and power resource sum respectively, can allow to insert this UE.Among this embodiment, owing to considered the topmost factor of restriction system capacity---code channel and power, therefore, when admitting control, can guarantee newly to insert the service rate (especially for the GBR business) of UE, can at utmost utilize simultaneously the code channel and the power resource of system again, therefore can improve the performance of system.

It should be noted that, if when carrying out power division according to dispatching algorithm, power and code channel resource can be changed mutually, when being resource allocation, under certain channel condition, can reduce the power resource that needs by the increase of code channel resource, perhaps can be by increasing the code channel resource that power resource reduces to be needed, then in code channel and the power, the factor of restriction system capacity may be based on wherein a kind of.At this moment, only needing one in decision condition 1 and the condition 2 gets final product.
