Description
Technical field
The present invention relates to wireless communication field, relate in particular to reverse admission control method, device and base station.
Background technology
At present, Traffic Channel in the wireless telecommunication system is with respect to power gain (the TrafficChannel to Pilot Channel transmit power ratio of pilot channel, be called for short: T2P) processing method is code division multiple access (Code Division Multiplex Access, be called for short: CDMA) 2000 1x only support evolution version (the Evolution Data Only of data service, be called for short: (Reverse Traffic Channel Medium Access Control is called for short: the core processing method of subtype (subtype) 3 RTC MAC) media access control protocol of reverse traffic channel EV-DO).(be called for short: the DOA system) in the revision version A of CDMA2000 EV-DO (RevA) system, introduced the notion of stream (flow), because homogeneous turbulence does not have different grades and different service quality (Quality of Service, be called for short: QoS) requirement, therefore prior art has adopted a kind of processing method of leaking bucket to come convection current to dispatch, and each stream all has a similar memory cell of leaking bucket to come storage resources.Fig. 1 is the schematic diagram of prior art power gain processing method.As shown in Figure 1, T2PInflow represents to inject the T2P resource of leaking the bucket memory cell, is current available T2P resource; PotentialT2POutflow is the potential T2P resource that current subframe can use; T2POutflow has then represented through the real T2P resource that flows out after the evaluation process, and promptly actual allocated is given user's T2P resource; BucketLevel shows the current state of bucket that leaks, and promptly leaks the current T2P stock number of accumulating of bucket, and BucketLevelSat represents to leak the maximum T2P stock number that bucket can hold.The T2P processing method comes each stream is dispatched by bringing in constant renewal in the leakage bucket.
As shown in Figure 1, the stream that grade is high, more T2P resource is arranged, can be dispatched faster, in a physical layer packet, can take more byte number, and can improve the grade of whole physical layer packet, thereby adopt higher T2P to send, therefore corresponding the mixing retransmits (Hybrid Automatic RepeatRequest automatically; Be called for short: HARQ) number of times also just still less, time delay is also just littler.Briefly, the T2P processing method has realized reverse rate scheduling, and the bag that has determined current subframe (subframe) to send out is long, the transmission mode of being given out a contract for a project, and the power of giving out a contract for a project.This processing method can realize the QoS with indoor (intra-user).
In 1X EV-DO Rev A system, the form with Business Stream between terminal and the base station is transmitted data.Terminal sent the request of connecting to the base station earlier before the base station transmits Business Stream; This base station allows each to connect with it to the terminal that it sends connection foundation request; Then, system is the traffic flow assignment T2P resource of this terminal transmission.In the prior art, system is that the method for traffic flow assignment T2P resource is: PF (pri function) curve that obtains the respective traffic flows that sets in advance; The load value of base station system is brought into described PF curve, thereby obtains the T2P resource that this Business Stream can be assigned to.
In realizing process of the present invention, the inventor finds that there are the following problems at least in the prior art: the base station allows each to connect with it to the terminal that it sends connection foundation request in the prior art, when the terminal use constantly inserts, terminal constantly increases to the Business Stream that the base station sends, and causes system loading constantly to increase; System can constantly reduce for the T2P resource that the user is assigned to thereupon; When there not being the T2P resource can divide timing,, can only just can reach the purpose that this terminal and base station connect by the service quality of all terminals in the reduction system if base station access by terminal is arranged again.But, this terminal and the QoS (quality of service requirement) of all terminals in the connecting system all can't be guaranteed.

Embodiment
To use the pri function curve in embodiments of the present invention, below it be carried out brief description:
In the DOA system, one accesses terminal and can support different stream to carry out reverse transfer.For example, operator is divided into Three Estate according to class of business with business: transmit class business (abbreviation: EF flows) fast, guarantee to transmit class business (abbreviation: AF flows) and transmit class business (abbreviation: BE stream) as far as possible.Wherein, homogeneous turbulence does not have different system parameters requirements when reverse transfer.Low as EF stream to bandwidth requirement, but to parameter request height such as time delay, shakes; AF stream needs the guarantee of bandwidth; The grade of BE stream is lower, and is also lower to the requirement of system parameters.The all kinds Business Stream has been defined different PF (pri function) curved surface for it in the T2P algorithm.This PF curved surface is a three-dimensional function, and input has 3 latitudes, is respectively FRAB (filtered busy not busy indication) axle, LoadAxis (system load) axle and T2Paxis (needing distribution T 2P resource) axle.More directly perceived for what represent, fixing FRAB value usually, thus on this cross section, find corresponding PF curve.The implication of this curve is, when the filtered busy spare time is designated as a certain fixed value, and when system loading reaches to a certain degree, the quantity of the average T 2P resource that corresponding reverse traffic stream can obtain.This curve is not directly definition in 1X EV-DO RevA system, but obtains by definition two function T 2PUp () and T2PDn ().The meaning of T2PUp () function curve is under certain system loading degree, when sector RAB is designated as the spare time, and the step-length that the T2P resource rises; The meaning of T2PDn () function curve is under certain system loading degree, when sector RAB is designated as when busy the step-length that the T2P resource descends.The PF curve then is these two results that function subtracts each other in the dB territory.Its derivation is as follows:
When the T2P resource allocation reached a kind of stable state, the T2P resource of every sub-frame allocation maintained a fixed value substantially, and promptly the rising total amount of T2P and decline total amount equate.Suppose that b is the ratio of the RAB of system for doing, and then has: T2PUp () * (1-b)=T2PDn () * b on linear domain
Be converted to: b/ (1-b)=T2PUp ()/T2PDn ()
Be transformed into the dB territory have 10log (b/ (1-b))=10log (T2PUp ())-10log (T2PDn ())=" PF
Therefore, by the value of T2PUp () and T2PDn () function, just can determine the shape of PF curve.
Be illustrated in figure 2 as BE stream at the priority curve of FRAB for-0.625 o'clock.This curve is by T2PUp () and these two function decisions of T2PDn (), and these two functions also all are the three-dimensional linear interpolating functions by FRAB, T2PAxis, three axle decisions of LoadAxis.When the FRAB value in (0.625,0.875) scope, the PF curve is identical.Therefore, under the fixing situation of FRAB, this moment the PF curve just to be reduced to T2PAxis and LoadAxis be the two-dimensional linear interpolating function of axle.
The coordinate that can obtain T2PUp () function interpolation point according to the agreement regulation is as follows: the value on the T2Paxis axle is respectively: T2PAxis00, T2PAxis01, T2PAxis02, T2PAxis03 among the T2P parameter set T2PTransitionFunctionNN (NN＞0); Value on the LoadAxis axle is respectively: T2PUpT2PAxis00FRABAxis4, T2PUpT2PAxis01FRABAxis4, T2PUpT2PAxis02FRABAxis4, T2PUpT2PAxis03FRABAxis4 among the T2P parameter set T2PTransitionFunctionNN (NN＞0).
The coordinate of T2PDn () function interpolation point is as follows: the value on the T2Paxis axle is respectively: T2PAxis00, T2PAxis01, T2PAxis02, T2PAxis03 among the T2P parameter set T2PTransitionFunctionNN (NN＞0); Value on the LoadAxis axle is respectively: T2PDnT2PAxis00FRABAxis4, T2PDnT2PAxis01FRABAxis4, T2PDnT2PAxis02FRABAxis4, T2PDnT2PAxis03FRABAxis4 among the T2P parameter set T2PTransitionFunctionNN (NN＞0).
What can release BE stream according to the interpolation point of two above-mentioned functions is-0.625 o'clock at FRAB, and the coordinate of the pairing interpolation point of priority curve is as follows:
Value on T2PAxis is respectively: T2PAxis00, T2PAxis01, T2PAxis02, T2PAxis03 among the T2P parameter set T2PTransitionFunctionNN (NN＞0); Value on LoadAxis is respectively: (T2PUpT2PAxis00FRABAxis4-T2PDnT2PAxis00FRABAxis4), (T2PUpT2PAxis01FRABAxis4-T2PDnT2PAxis01FRABAxis4), (T2PUpT2PAxis02FRABAxis4-T2PDnT2PAxis02FRABAxis4), (T2PUpT2PAxis03FRABAxis4-T2PDnT2PAxis03FRABAxis4) among the T2P parameter set T2PTransitionFunctionNN (NN＞0).Like this four interpolation points are connected, just obtained the priority curve of BE stream.
For the unconfined permission Business Stream of resolution system inserts, cause the problem of the QoS difference of access service stream, the embodiment of the invention provides a kind of reverse admission control method, device and base station.
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail:
The embodiment of the invention provides a kind of reverse admission control method, is illustrated in figure 3 as the reverse admission control method flow chart of the embodiment of the invention, may further comprise the steps:
S301: the access threshold value of obtaining all kinds Business Stream in advance;
S302: receive to set up the connection request of eating dishes without rice or wine, determine that described request determines traffic flow types,, from the access threshold value of the various traffic streams obtained in advance, determine the access threshold value of this Business Stream according to this traffic flow types;
S303: obtain system's present load;
S304: judge that whether system's present load is smaller or equal to described access threshold value;
If the present load of system smaller or equal to described access threshold value, then allows to set up this and eats dishes without rice or wine to connect; Otherwise, forbid setting up this and eat dishes without rice or wine to connect.
Along with the continuous increase of access service stream in the system, the load of system also constantly promotes, and can not give request access service stream distribution T 2P resource again up to system; In order to ensure the service quality and the stability of a system of access service stream, the embodiment of the invention further comprises the steps:
Obtain the dismounting threshold value of all kinds Business Stream in advance;
The present load of acquisition system;
Select and remove the Business Stream that thresholding is not higher than present load;
In all kinds Business Stream of selecting, determine the poorest Business Stream of service quality;
Disconnect this Business Stream and system eat dishes without rice or wine be connected.
Wherein, described dismounting thresholding is, in the priority curve, and the load value when being zero with respect to the power gain of pilot channel than resource system assignment for the Traffic Channel of the minimum of corresponding Business Stream.
Below reverse admission control method is elaborated:
S301: the access threshold value of obtaining all kinds Business Stream in advance; As shown in Figure 4, may further comprise the steps:
S401: determine that terminal sends all kinds Business Stream, system is for satisfying the minimum-rate that its quality of service requirement disposes;
S402: the Traffic Channel of obtaining corresponding minimum by described minimum-rate compares resource with respect to the power gain of pilot channel; Concretely, the described terminal minimum-rate of setting up Business Stream can transmit the needed T2P resource of minimum-rate by be protected this Business Stream of following form.For example: suppose that operator ensures that the minimum speed limit of the qos requirement of reverse BE Business Stream is 38.4kbps, looking into the bag length that following table obtains its correspondence is 1024bit, and the T2P resource that needs is 10dB.
| Packet Size (bits) | Data Rates (after 16-slots) | Average T2P |
| 128 | 4.8 | 0.75 |
| 256 | 9.6 | 3.75 |
| 512 | 19.2 | 7 |
| 768 | 28.8 | 8.75 |
| 1024 | 38.4 | 10 |
| 1536 | 57.6 | 11 |
| 2048 | 76.8 | 13 |
| 3072 | 115.2 | 14.25 |
| 4096 | 153.6 | 15.5 |
| 6144 | 230.4 | 17 |
| 8192 | 307.2 | 18.5 |
| 12288 | 460.8 | 21.25 |
S403: according to the Traffic Channel of described minimum with respect to the power gain of pilot channel than resource, on the priority curve, obtain the access threshold value of all kinds Business Stream.Wherein, described access threshold value is to send all kinds traffic stream service quality requirement, the maximum of system's present load for satisfying terminal.For example: above-mentioned hypothesis operator ensures that the minimum speed limit of the qos requirement of reverse BE Business Stream is 38.4kbps, at first looking into the bag length that table obtains this Business Stream correspondence is 1024bit, the T2P resource that needs is 10dB, then, according to two-dimensional linear interpolating function computational methods, the T2P resource is updated in the PF curve of this Business Stream, the dB thresholding that calculates corresponding system load value b/ (1-b) is the access threshold value.
S303: obtain system's present load; As shown in Figure 5, comprise the steps:
S501: set up when eating dishes without rice or wine connection request the busy not busy ratio of system in the measurement period of base station when system receives; Wherein, comprise the traffic flow types that to set up in the described request; The number of the busy indication RAB=1 of terminal is handed down to by register system in described base station, and counting ratio busy in the cycle is b, thereby can calculate the busy not busy than being b/ (1-b) of system;
S502: it is not busy than the current load value that is converted to system to hurry, will hurry exactly the spare time than b/ (1-b) be transformed into the dB territory just can push away the current load value of system.
Below by specific embodiment shown in Figure 2 the above-mentioned dismounting thresholding that obtains all kinds Business Stream is described:
As shown in Figure 2, the PF curve that flows for BE.The intersection value of the embodiment of the invention PF curve and the longitudinal axis (bearing axle) is set to remove threshold value.Because along with the terminal of connecting system be on the increase that access service stream also increases accordingly or system in the continuous lifting of sector interference, when system load value rises to the intersection point of the PF curve and the longitudinal axis, this moment, the current load value of system was 10dB, the T2P resource of distributing to corresponding BE stream is 0dB, this just means the setting according to this Business Stream priority, and system can not give corresponding BE traffic flow assignment resource this moment.Therefore, when system's current load value reached this thresholding, the judgement of removing the terminal access service stream was made in the base station.
The oppositely the highest Business Stream of Packet Error Ratio (PER) is chosen in the system in the base station, discharges eating dishes without rice or wine between this Business Stream and the system and is connected.During to next cycle, if load has still reached the dismounting thresholding in the system, the base station can continue to make and removes judgement, and then the base station is continued eating dishes without rice or wine between oppositely PER is the highest in the delivery system Business Stream and the system and is connected, reduces to below the dismounting thresholding until system load.
The reverse admission control method that the embodiment of the invention provides, for the service quality of assurance system access service stream, system has set up the access thresholding for the Business Stream that request inserts; By the present load of comparison system and the size of access threshold value, whether decision allows new Business Stream to be linked in the system; If the present load of system can be satisfied the required minimum load value of Business Stream that request inserts, system just allows this Business Stream to insert; Otherwise do not allow this Business Stream to insert.Compare with the scheme of the unconfined permission Business Stream of prior art connecting system; The embodiment of the invention has not only guaranteed in the system service quality of access service stream; And, ensured the stability of system.Also be provided with the dismounting thresholding in embodiments of the present invention, by judging whether system's current load value reaches the dismounting thresholding, determine whether removing the highest Business Stream of reverse Packet Error Ratio and system eat dishes without rice or wine be connected, can ensure the stability of system from reducing the present load of system in essence like this.
