Description

In UMTS based on the wireless access control method of multi-service priority
Technical field
The present invention relates to a kind of wireless access control method that in the third generation (3G) mobile communication system UMTS (UniversalMobile Telecommunication System, universal mobile telecommunications system), carries out load adjustment and rate consulation according to sub-district radio bearers situation and requested service access priority.This method is according to the situation of different business load in the cell load, under the wireless traffic overload situation in sub-district, make way for the strategy of high-priority service adjusts flexibly the cell load business according to low priority traffice, and can adjust the transmission rate of access service, maximize the quantity of high priority and real-time service in this sub-district, satisfy the requirement of system.
Background technology
In 3-G (Generation Three mobile communication system) UMTS, the network planning no longer relates to the problem of channel allocation, but wireless access control is because " soft capacity " problem in WCDMA (Wideband Code Division MultipleAccess, the Wideband Code Division Multiple Access (WCDMA)) system becomes very complicated.
In fact, the WCDMA system is an interference limiting system, can't reflect its cell capacity by calling out linking number at all.Can inserting certain calling, can all have existed calling keep required signal to noise ratio (SIR) to decide according to inserting after this calling this sub-district.Sir value is the ratio of received power and interference level, and the distance of it and power control mechanism and calling party and base station distance has confidential relation.Because each base station transmitting power is limited, near more from the base station as the calling party, the required transmitting power in base station is more little, but the access customer number order is just many more.The power control of being adopted among the UMTS makes receiver obtain suitable performance index by adjusting SIR, as the Block Error Rate (BLER) and the error rate (BER).Received power changes more greatly, and the target SIR value needs just high more.Insert request so can insert certain, confidential relation is arranged with the load state of current area and the type of service of access request itself (needing different power and SIR level to keep the desired quality of this business).
When inserting request, certain can bring two kinds of situations when inserting:
1. this request is normally inserted, and other users come back to poised state because of the variation of disturbing in the sub-district under power control;
2. should business be inserted by mistake, certain user in the sub-district causes call drop because the variation of disturbing can not get back to poised state under power control.Main because interference level is too high, and transmit power limited causes SIR can not reach some professional needed minimum SIR level.
In the ideal case, wireless access control method only can normally insert this calling party, just is access in when other users can reach poised state.But this perfect condition only just may exist when obtaining the accurate information of all-calls user propagation channel.Actual way is to determine whether inserting this calling party according to the partial information that is obtained in the sub-district.
Wireless access control adopts following several method basically at present.
Interactive connection control method: this method also is a kind of connection control method of perfect condition.This method is asked first access with the calling party, and tests all user SIR and whether can reach poised state and determine whether inserting this call request.This method because can run into serious convergence problem when whether the test subscriber reaches poised state, and can't be assessed non real-time user's convergence situation in real-time system and inapplicable.
Connection control method based on power: this method is come controlling call user's access according to the relation of capacity in cdma system and Power Limitation.Under descending situation, base station transmitting power is limited, and whether connection control method can be called out required transmitting power according to this and can make base station transmitting power exceed total emission power limiting and judge whether to insert this calling.
Based on the connection control method that disturbs: for fear of mobile phone when the up access control frequently to base station report power level, the current area load can be assessed by measuring current interference level in the base station, and judges whether insert this calling according to inserting the noise elevated levels that the calling party caused.
Based on the connection control method that call out to connect: this method is converted into the number that the calling that can insert connects to the average size of sub-district, implements very simple.But in the WCDMA system, because the relation of " soft capacity ", this method efficient is lower, and practicality is relatively poor.
In UMTS, the general connection control method based on interference in up employing connection control method discussed above is at the descending connection control method that then adopts based on power.Connection control method is assessed uplink and downlink respectively owing to inserting new the calling or the change load rise that RAB caused, and has only when satisfying uplink and downlink access criterion simultaneously, and this new access request could be granted to be inserted.
Traditional wireless access control method flow chart as shown in Figure 1.When receiving new call request, handoff request or transmission channel change on carrier frequency C1, flow process advances to step SP102 from step SP101.
In step SP102, whether wireless access control method detects the overload warning, if there is wireless overload warning, then handling process advances to step SP108, refuses described new request and end process.
If judging in step SP102 does not have wireless overload warning, then in step SP103, detect this request back uplink interference of access and whether surpass thresholding, determine whether to receive the uplink service request.If determine to receive the uplink service request, then handling process advances to step SP108, refuses described new request and end process.
Do not surpass thresholding if in step SP103, determine to insert this request back uplink interference, whether then in step SP104, detect down transmitting power, determine whether to receive descending real-time business request greater than total transmitting power.If determine to receive descending real-time business request, then handling process advances to step SP108, refuses described new request and end process.
If determine that in step SP104 down transmitting power is not more than total transmitting power, then base stations detected hardware resource in step SP105 determines whether BTS hardware transships.If BTS hardware transships, then handling process advances to step SP108, refuses described new request and end process.
If determine that in step SP105 the BTS hardware resource is enough, then in step SP106, detect the channel code resource, determined whether the channel code distribution.If there is not channel code can distribute to new access request, then handling process advances to step SP108, refuses described new request and end process.
If determine to be the new request distributing channel mode that inserts in step SP106, handling process advances to step SP107.In step SP107, after all above-mentioned detections were all passed through, described request was access in.
But the cut-in method of present this routine can not satisfy the requirement of wireless access control among the UMTS fully, and they put on an equal footing the user of different priorities, and the adjustment of load flexibly is not tactful after overload.
Summary of the invention
Consider the multi-service user of UMTS system and the characteristics of multipriority service access, the present invention proposes among a kind of UMTS the wireless access control method based on multi-service, multipriority and rate consulation.
According to the present invention, a kind of wireless access control method of consulting based on multi-service, multipriority and transmission rate in the UMTS system is provided, it is characterized in that comprising the following steps: a) to be provided with the priority of new access request according to the multiple services QoS of request; B) calculate all professional total loads that comprise described new access request in the sub-district that this new access request will insert; C) detect according to the total load of being calculated in the step b) whether wireless overload warning is arranged in the sub-district that this new access request will insert; D) if detected the warning of wireless overload in step c), the transmission rate that then reduces the low business of the priority of the described new access request of priority ratio lowers the total load level, returns step b); E) if in step c), do not detect wireless overload warning, then insert described new access request.
Wherein, the warning of wireless overload is defined as " pre-overload " state and " overload " state by load control unit according to the capacity of current load condition and sub-district, if detected wireless overload warning does not then insert described new access request for " overload " state in step d).
According to the situation of wireless access control method of the present invention according to different business load in the cell load, under the wireless traffic overload situation in sub-district, make way for the strategy of high-priority service adjusts flexibly the cell load business according to low priority traffice, and can adjust the transmission rate of access service, maximize the quantity of high priority and real-time service in this sub-district, thereby satisfy the requirement of system.

Embodiment
Describe the preferred embodiments of the present invention in detail below in conjunction with accompanying drawing.How in the present invention, according to 3GPP (3 RdGeneration partnership project) QoS (Quality of Service, quality of service) classification, all are inserted the user classifies according to its priority, and according to the priority that inserts the user, inserting under the congested situation, carry out rational rate consulation and maximize high-priority users.
Basic thought of the present invention is, the user of high priority user than low priority when inserting enjoys higher authority, the user of low priority is ready that when congested the access message transmission rate of sacrifice (reduction) oneself lowers the load level, thereby allows high-priority users insert.If the user QoS of low priority does not have the requirement of real-time, when congested acquiring a certain degree, the user of low priority even be suspended allows the high and real-time access customer number of priority reach maximum.After this cell load reduced, the user that these low priorities and low real-time require can be allowed to carry out transfer of data again and be improved the peak transfer rate that oneself speed is asked to reach gradually.
Table 1 illustrates the defined priority of classifying according to different business user QoS.
Table 1 is according to the QoS defined priority of classifying
Figure C0382669600091
It should be noted that classification 3, can further this type of service priority be subdivided into the n class according to " Traffichandling priority " (Business Processing grade) in RAB (radio access bearer) attribute.
Be described with reference to the accompanying drawings according to wireless access control method of the present invention based on above-mentioned classification below.Fig. 2 illustrates according to of the present invention in the UMTS system, the flow chart of the wireless access control method of consulting based on multi-service, multipriority and transmission rate.
As shown in Figure 2, at step SP1, when receiving new call request, handoff request or transmission channel change on carrier frequency C1, according to the RAB attribute, according to the classification of table 1, it is Q that this user's Request Priority classification is set.If should business be compound business (multiple business combination), then according to its access priority of lowest priority business setting in this composite services.For example, when access service is " session+backstage ", according to " backstage " business setting Q=4 of low priority wherein.
Then, carry out initialization and P=4 is set, i=3.Wherein, the priority service rank that on behalf of minimum permission, P insert, it is 3 that i represents professional adjustable transmission rate grade, as for " data flow " and " alternately " user, adjustable transmission rate is respectively 128kps, 64kbps, 28.8kbps and 384kbps, 128kbps, 64kbps.Minimum transmission rate R1 is respectively 28.8kbps and 64kbps.In the middle of the Qos of table 1 classification, priority x=1 and 2 is a real-time service, and requires minimum transmission rate (Guaranteed bit rate).Therefore, though x=1 class service priority is greater than x=2 class business, but the time when wireless traffic overload and the access of Q=i class service request, priority x=2 class business can be reduced to transmission rate minimum transmission rate at most, and non-real-time services such as priority x=3 or x=4 class then may be suspended or discharge.
Then,, calculate the uplink and downlink total load of current area medium priority from 1 to P according to following described formula at step SP2, and when overload, hang up or the Release priority level greater than all business of P.The computational methods of relevant uplink and downlink total load for example, are calculated according to uplink interference as up, and descending according to transmitting power calculating, at HarriHolma, and Antti Toskala shows, JohnWiley﹠amp; Describe in detail in " WCDMA for UMTS " chapter 9 that Sons calendar year 2001 publishes, omit at this.
L UL = Σ P = 1 P L UL , p
L DL = Σ P = 1 P L DL , p
L wherein UL, pAnd L DL, pBe that all priority are the uplink and downlink business load of p, L ULAnd L DLIt is this sub-district uplink and downlink total load.
Next, whether in step SP3, detecting current area has the overload warning of being sent by " load control (LC) " unit, if the overload warning appears in uplink and downlink, then enter transmission rate negotiation section (step SP4～SP5, SP51～54, and SP20) based on priority, if the overload warning does not occur, then enter normal access load detecting part (step SP6, SP71～SP72, SP81～SP85, SP9, and SP11～SP14).
Both of these case is described respectively below.
At first, if in step SP3, detected the overload warning, then detect the state of wireless overload at step SP4.
Wireless mistake is loaded with two states, and " pre-overload " state and " overload " state determined according to the capacity of present load state and sub-district by " load control (LC) " unit.
If determine that in step SP4 " overload " state occurs, show that then this cell-overload is quite serious, be not suitable for inserting any request, adjust cell load by " load control (LC) " unit and get back to normal condition.At this moment, handling process advances to step SP20, and refusal inserts newly asks and finish whole flow process.
In step SP4, when " pre-overload " when state occurs, show that this moment, cell load might transship, can adjust according to the priority that inserts request, allow high-priority service to insert and prevent that low priority user from inserting.At this moment, handling process advances to step SP5.
In step SP5, if determine to insert Request Priority Q=4, show that this accesss request is a lowest priority, then handling process advances to step SP20, and this request is rejected immediately and finishes whole flow process.
If determine that in step SP5 inserting Request Priority Q is not equal to 4, then handling process proceeds to step SP51.
In step SP51, judge and insert whether Request Priority is 4＞Q 〉=3.If determine to insert Request Priority 4＞Q 〉=3, then this service request is " alternately " class business, and handling process advances to step SP53.If in step SP51, determine to insert Request Priority Q＜3, should business be the higher real-time service of priority then, handling process advances to step SP52.
In step SP53, after determine inserting Request Priority 4＞Q 〉=3, at first hang up or refusal, and the business of sub-district medium priority x=Q is carried out " rate consulation " being in the business that access state and priority is lower than Q in the sub-district at present, that is, with the business load transmission rate R of same priority x=Q jBe reduced to next rank R simultaneously j=R J-1Such as, insert customer service priority Q=3.1, when overload, the service transmission rate of all x=3.1 can be from R 3=384kbps drops to R gradually 1=32kbps, and the higher priority user is unaffected.
Then, handling process advances to step SP54, after this determines through " rate consulation ", whether can guarantee the business load transmission rate R of same priority x=Q jGreater than its minimum transmission rate R 1If can guarantee the business load transmission rate R of same priority x=Q jGreater than its minimum transmission rate R 1, then explanation might allow to insert this new service request, and flow process is returned step SP2.Otherwise handling process advances to step SP20, refuses this new service request and finishes whole flow process.
In step SP52, after determining to insert Request Priority Q＜3, this business is the higher real-time service of priority.At this moment, for quickening method is regulated the speed, the real-time that guarantees service request requires and minimum transmission rate (Guaranteed bit rate) requirement, at first non-real-time services such as priority x=3 or x=4 class are hung up or release, progressively reduce priority x=2 class service transmission rate then, until minimum transmission rate.Equally, after this " rate consulation ", handling process also advances to step SP54.In step SP54, determine whether to guarantee the load transmission rate R of priority x=2 class business iGreater than its minimum transmission rate R 1If can guarantee the load transmission rate R of priority x=2 class business iGreater than its minimum transmission rate R 1, then explanation might allow to insert this new service request, and flow process is returned step SP2.
All priority x=2 service transmission rates are adjusted to minimum transmission rate when the sub-district, and the sub-district still is in overload, and handling process advances to step SP20 so, and this service request will be rejected and finish whole flow process.
After transmission rate was reduced to a certain degree, cell load no longer was in overload, and then this priority service just can be access in, and entered normal access load detecting part then.
The normal load that describes below when not having wireless overload to warn in determining the sub-district inserts detection.
Do not have the overload warning if in step SP3, judge the sub-district, show that then present sub-district is in the normal load state.Handling process advances to step SP6.
When being in the normal load state in the sub-district, need to check the access service request after, whether the sub-district still retainable normal load poised state.And it is relevant with loadtype whether to insert new load, and the criterion of real-time service and non-real-time service is different, and method is also different.If should business be compound business (multiple business combination), then real-time and non real-time all will be checked, have only when all composite services all just can be access in when checking.
At first, in step SP6, judge that the type of RAB is real-time loadtype or non real-time loadtype.If real-time loadtype, then handling process advances to step SP71.If the non real-time loadtype, then handling process advances to step SP72.Carry out concrete description at these two kinds of service conditions respectively below.
For real time business,,, search and select suitable carrier frequency Cm according to the specific requirement of each carrier frequency loading condition and professional classification situation and operator at step SP71.For example, can new service request be inserted the lighter sub-district of load according to " balanced load " algorithm.Also can be according to " professional classification " algorithm, the business that transmission rate request is higher and the lower business of transmission rate request insert the sub-district of different carrier frequency respectively.
Then, in step SP81, check the ascending load of new request real time business, determine whether to receive the uplink real-time service request.If this moment, uplink service surpassed load-threshold, then handling process advances to step SP85, and this request is rejected and finishes whole flow process.
If determine to receive this uplink real-time service request in step SP81, then handling process proceeds to step SP83.In step SP83, check the down load of new request real time business, determine whether to receive descending real-time business request.If this moment, downlink business surpassed load-threshold, then handling process advances to step SP85, and this request is rejected and finishes whole flow process.
If determine to receive this descending real-time business request in step SP83, then handling process proceeds to step SP9.
Equally, for non-real-time service,,, search and select suitable carrier frequency Cm according to the specific requirement of each carrier frequency loading condition and professional classification situation and operator at step SP72.For example, can new service request be inserted the lighter sub-district of load according to " balanced load " algorithm.Also can be according to " professional classification " algorithm, the business that transmission rate request is higher and the lower business of transmission rate request insert the sub-district of different carrier frequency respectively.
Then, in step SP82, check the ascending load of new request non-real-time service, determine whether to receive up non-real-time service request.If this moment, uplink service surpassed load-threshold, then handling process advances to step SP85, and this request is rejected and finishes whole flow process.
If determine to receive this up non-real-time service request in step SP82, then handling process proceeds to step SP84.In step SP84, check the down load of new request non-real-time service, determine whether to receive descending non-real-time service request.If this moment, downlink business surpassed load-threshold, then handling process advances to step SP85, and this request is rejected and finishes whole flow process.
If determine to receive this descending non-real-time service request in step SP84, then handling process proceeds to step SP9.
Should be noted that, in above-mentioned processing, need check the uplink and downlink load of new request real time business and non-real-time service respectively according to the business situation of classifying.Under the situation of compound business (multiple business combination), then all business all will be checked in this composite services.If the professional load-threshold that surpasses of the upstream or downstream of any business wherein, then this request is rejected and finishes whole flow process.
When all Radio Resources all check pass through after, when promptly allow inserting new service request, at step SP9, whether the base stations detected hardware resource satisfies the demand of this request of access.If the BTS hardware resource can not satisfy the demand of this new request of access, then handling process advances to step SP20, refuses this request and finishes whole flow process.
If judge that in step SP9 the BTS hardware resource can satisfy the demand of this new request of access, check in step SP11 that then this sub-district has or not unnecessary channel code to distribute, do not distribute to this new request if there is unnecessary channel code, then handling process advances to step SP20, refuses this request and finishes whole flow process.
If determining has unnecessary channel code to distribute to this new request in the sub-district, determine in step SP12 then whether Cm equals C1 in step SP11.If Cm=C1 then inserts this request on the C1 carrier frequency in step SP14; As Cm ≠ C1, then in step SP13, insert this request, and initiate direct-cut operation to carrier frequency Cm.
As can be seen from the above description, the wireless access control method that in the third generation (3G) mobile communication system UNITS, carries out load adjustment and rate consulation disclosed in this invention according to sub-district radio bearers situation and requested service access priority, can be according to the situation of different business load in the cell load, under the wireless traffic overload situation in sub-district, make way for the strategy of high-priority service adjusts flexibly the cell load business according to low priority traffice, and can adjust the transmission rate of access service, thereby maximize the quantity of high priority and real-time service in this sub-district, satisfy the requirement of system.
More than although the present invention has been described according to the preferred embodiment, can in the spirit and scope of present disclosure, further revise the present invention.Thereby the application covers any modification of the present invention, use or modification by its general principles.In addition, the application is intended to cover from the relevant with the present invention technically of present disclosure and the known or coml practice within the qualification of appended claims.
