Description
Technical field
The present invention relates to admission control technique, particularly a kind of admittance control method that uses negotiation mechanism.
Background technology
Wideband Code Division Multiple Access (WCDMA) (WCDMA) system is a kind of advanced in performance cell mobile communication systems, and base station controller (RNC) is as the control core of the RRM of WCDMA system, the Radio Resource of management and dispatching whole system.
Wherein, the power resource of air interface is one of very important Radio Resource.In the WCDMA system, when new professional of one of access, for up link, total interference level that system receives, promptly total received power in broadband (RTWP) will improve; For down link, the down transmitting power of base station, promptly carrier transmit power (TCP) also will promote.In an overload system, the rising of RTWP or TCP all may cause speech quality to descend, and may cause the large tracts of land call drop when serious.
At present, for the communication quality of original business in the assurance system, sub-district cover and the utilance of resource, RNC has adopted certain admission control technique to come the sub-district access service is controlled.Switch when a mobile subscriber initiates new calling or application in a new sub-district, perhaps increase a new business in an existing calling procedure, perhaps existing business is carried out channel when reshuffling, RNC all will carry out access control.In the WCDMA system, access control is carried out respectively in up link and down link, that is to say, whole access control is divided into two parts: up access control and descending access control, have only the access control of uplink and downlink all to adjudicate in the time of can inserting new business, RNC just can admit this new business.But existing technology is when carrying out the upstream or downstream access control, and " comparison " mode of employing is handled.Existing scheme has following several usually: one, the number of users thresholding is set, does not surpass under the condition of thresholding at number of users, insert new user; Otherwise refusal inserts new user; Two, the load level of system after the estimation access new business compares this load horizontal estimated value and the load-threshold that is provided with in advance then, as if above load-threshold, just accepts this access request; Otherwise refuse this access request; Such as, the total down transmitting power thresholding in base station is set, obtain the current down transmitting power in base station, and with this down transmitting power and the power discreet value summation that is provided with for the new business of applying for access, as if the power that obtains with less than the total down transmitting power thresholding in base station, then insert new business, otherwise refusal inserts new business; Three, the thresholding that other is set according to managerial demand compares and determines whether inserting new business.
Because, in the WCDMA system,, business can be divided in real time and non-real-time service two classes according to the service performance requirement of business; Cause according to business and the controllability of load business can also be divided into controlled and uncontrollable professional two classes.Controllable traffic refers to those to the insensitive business of time delay, i.e. non-real-time service, as: Packet Service and adaptive multi-rate (AMR) speech business etc.; Uncontrollable business refer to those to delay sensitive, have the business of speed or minimum-rate restriction, i.e. real time business is as the AMR speech business of minimum-rate etc.Wherein, the load that is produced by controllable traffic is a controllable load, be uncontrollable load by the uncontrollable professional load that produces, thereby cell load is dimerous by controllable load and uncontrollable load.Therefore, the business that existing business of system and request insert all might be a controllable traffic, and the load of its generation also might be controllable load.Like this, for these controllable traffic, system not only can carry out access control by mode relatively, can also adjust in conjunction with speed controllable traffic, promptly carry out the mode of service negotiation, come the access of new business is controlled, thereby make the power system capacity maximization, Radio Resource is fully used.
But, existing access control scheme is all carried out service negotiation less than considering to controllable traffic, only use absolute " comparison " mode to control the access of new business, make some can also be rejected access by the new business that service negotiation inserts originally, therefore, existing technical scheme can not make full use of system resource and carries out access control.
Summary of the invention
In view of this, main purpose of the present invention is to provide a kind of admittance control method that uses negotiation mechanism, make RNC when carrying out access control, new business to existing controllable traffic of system and application access is carried out service negotiation, thereby make the power system capacity maximization, make full use of the Radio Resource of system.

Embodiment
The present invention is further described in more detail below in conjunction with drawings and the specific embodiments.
In the methods of the invention, the new business type with the application access is divided into: controllable traffic and uncontrollable business; The existing service conditions of current area is divided into: no controllable traffic with controllable traffic is arranged; The cell load desired value is set and current area load level is divided into: cell load is higher than load target value and cell load is lower than load target value.In following examples, in new business, controllable traffic is expressed as C, and uncontrollable traffic table is shown NC; In the existing service conditions of current area, no controllable traffic is expressed as CSN, has controllable traffic to be expressed as CSI; In current area load level, cell load is higher than load target value and is expressed as H, and cell load is lower than load target value and is expressed as L.
According to the regulation of the invention described above method, access control can be divided into following eight kinds of situations:
Situation one, current area load level are that the existing service conditions of L, current area is that CSN, new business type are NC.
Situation two, current area load level are that the existing service conditions of L, current area is that CSN, new business type are C.
Situation three, current area load level are that the existing service conditions of L, current area is that CSI, new business type are NC.
Situation four, current area load level are that the existing service conditions of L, current area is that CSI, new business type are C.
Situation five, current area load level are that the existing service conditions of H, current area is that CSN, new business type are NC.
Situation six, current area load level are that the existing service conditions of H, current area is that CSN, new business type are C.
Situation seven, current area load level are that the existing service conditions of H, current area is that CSI, new business type are C.
Situation eight, current area load level are that the existing service conditions of H, current area is that CSI, new business type are NC.
In the methods of the invention, system is provided with load target value for each sub-district in advance, receive the access request of new business as RNC after, main treatment step is as follows:
After a.RNC receives the access request of new business, obtain the new business type according to the new business services performance requirement in this access request, obtain the load measure value of present access subzone simultaneously and analyze the composition of current existing business, obtain the existing service conditions of current area load level and current area;
B. judge whether current area load level is lower than the cell load desired value, if current area load level is lower than the cell load desired value, execution in step c then; If current area load level is higher than the cell load desired value, and controllable traffic or new business are arranged in the existing business is controllable traffic, then execution in step d; If current area load level is higher than the cell load desired value, and existing professional and new business is uncontrollable business, then refuses this access request, the end access control;
C. judge that can current area insert this new business,, then accept this access request, finish access control if can insert new business; If can not insert new business, and controllable traffic or new business are arranged in the existing business is controllable traffic, execution in step d; If can not insert new business, and existing professional and new business is uncontrollable business, then refuses this access request, the end access control.
D. according to current existing service conditions and new business type, controllable traffic in definite existing business or the controlled new business or the rate adjustment scheme of the two combination, can judgement insert new business by current area after this project setting speed, if can, then adjust speed by this rate adjustment scheme, accept this access request, finish access control; Otherwise refuse this access request, finish access control.
Main treatment step based on above this method is illustrated respectively the access control of described eight kinds of situations respectively below in conjunction with accompanying drawing.
For situation one: current area load level is that the existing service conditions of L, current area is that CSN, new business type are NC, and system adopts the method for disposable comparison, and can judgement insert new business with request rate, thereby whether decision inserts new business.Fig. 1 is the access control one preferred embodiment handling process schematic diagram of the inventive method for situation one.As shown in Figure 1, concrete treatment step is as follows:
Step 101:RNC is according to parameters such as request rate in current area load measure value, the new business services performance requirement and types of service, estimates the load level of whole sub-district after the access new business.
Wherein, the base station measurements that can use total interference of cell uplink or downlink gross power in the inventive method is as cell load, also can use of the definition of the load factor of business throughput rate or equipment demodulation ability as load, but be not limited to above definition, also comprise the emerging load definition that may be used for correlation analysis of WeiLai Technology development; When the cell load level of estimating after new business inserts, if new service request is to be produced by low the rising because of the speed of related algorithm with certain link, then the current area load is deducted the existing load of this link, again according to the request rate of new business etc., estimate to insert the load level of whole sub-district after the new business.
In addition, the concrete scheme that is converted into loading index for the method for estimation of cell load, employed load measurement index, load measure value among the present invention all is not limited to a kind of, can adopt different load estimating methods, load measurement index and load measure value to be converted into the scheme of loading index according to actual needs, because it is not emphasis of the present invention that load estimating method, load measurement index and load measure value are converted into the scheme of loading index, therefore do not do detailed description here.
Step 102: whether the cell load horizontal estimated value that determining step 101 obtains is greater than the load target value of this sub-district, if change step 103 over to; Otherwise change step 104 over to.
Step 103: refuse this access request, finish access control.
Step 104: accept this access request, finish access control.
Because so-called system available bandwidth is exactly under the restriction of cell load desired value, uses the parameters such as type of service in present load horizontal survey result, the new business services performance requirement, calculates the spendable maximum rate of this new business.Therefore, system's available bandwidth carries out access control after can also estimating here to insert new business, and then above-mentioned steps 101 and step 102 are corresponding becomes:
Step 101:RNC calculates current system available bandwidth according to the parameters such as type of service in present load horizontal survey result, the new business services performance requirement; Step 102: whether the estimated system's available bandwidth of determining step 101 is less than the request rate in the new business services performance requirement, if change step 103 over to; Otherwise change step 104 over to; Here, the concrete grammar of estimating system available bandwidth does not belong to emphasis of the present invention, does not therefore do detailed description.
For situation two: current area load level is that the existing service conditions of L, current area is that CSN, new business type are C, and can system at first judge and insert new business with request rate, if can, then accept this access request; Otherwise, the rate adjustment scheme of determining new business is promptly: the access rate of setting new business is estimated system's available bandwidth, judge that then can new business insert the sub-district with system's available bandwidth, thereby decision is to insert this new business or this access request of refusal with this system's available bandwidth.Fig. 2 is the access control one preferred embodiment handling process schematic diagram of the inventive method for situation two.As shown in Figure 2, concrete treatment step is as follows:
Request rate and type of service during step 201:RNC requires according to the service performance of current area load measure value and new business are estimated the load level of whole sub-district after the access new business.
Step 202: whether the cell load horizontal estimated value that determining step 201 obtains greater than the load target value of this sub-district, if, execution in step 203; Otherwise execution in step 207.
Step 203: the type of service during system requires according to the service performance of current area load measure value and new business is estimated the available bandwidth of system after the access new business, the rate adjustment scheme of determining new business promptly: the access rate of setting new business is estimated system's available bandwidth.
Such as: with the base station measurements of descending carrier transmitting power during as the cell load measured value, if current carrier transmit power is 75%, new business is the AMR speech business, the current area load-threshold is that the carrier transmit power threshold is 80%, then can estimate current supporting rate is 10kbps, therefore, current system available bandwidth is 10kb.
Step 204: whether the estimated system's available bandwidth of determining step 203 is less than the minimum-rate requirement in this new business services performance requirement, if change step 205 over to; Otherwise change step 206 over to.
Step 205: refuse the access request of this new business, finish access control.
Step 206: the available bandwidth that step 203 is estimated is configured to the access rate of new business.
Because system's available bandwidth is to estimate to obtain under certain system load threshold constraints, be that estimated admissible rate inserts new business therefore with available bandwidth, cell load is exceeded standard.
Wherein, the inventive method is not revised the maximum rate in the new business services performance requirement for new business configuration admissible rate the time, and the speed of configuration new business can dispose by basic resources to be finished.
Step 207: accept the access request of this new business, finish access control.
In addition, also can at first estimate to insert system's available bandwidth after the new business here, then above-mentioned steps 201 becomes to step 204 is corresponding:
Step 201:RNC calculates current system available bandwidth according to the parameters such as type of service in present load horizontal survey result, the new business services performance requirement; Step 202: whether the estimated system's available bandwidth of determining step 201 is less than the request rate in the new business services performance requirement, if change step 204 over to; Otherwise change step 207 over to; Step 203 cancellation; Step 204: whether the estimated system's available bandwidth of determining step 201 is less than the minimum-rate in the new business services performance requirement, if change step 205 over to; Otherwise change step 206 over to.
For situation three: current area load level is that the existing service conditions of L, current area is that CSI, new business type are NC, and can system at first judge and insert new business with request rate, if can, then accept this access request; Otherwise, determine existing controllable traffic rate adjustment scheme, reconvict and on the basis of this rate adjustment scheme, to insert new business, thereby decision is by inserting new business or this access request of refusal after the speed of the existing controllable traffic of this rate adjustment scheme adjustment.Fig. 3 is the access control one preferred embodiment handling process schematic diagram of the inventive method for situation three.As shown in Figure 3, concrete treatment step is as follows:
Request rate and type of service during step 301:RNC requires according to the service performance of current area load measure value and new business are estimated the load level of whole sub-district after the access new business.
Step 302: whether the cell load horizontal estimated value that determining step 301 obtains is greater than the load target value of this sub-district, if change step 303 over to; Otherwise change step 308 over to.
Wherein, the processing of step 301 and step 302 also can for:
Step 301:RNC calculates current system available bandwidth according to the parameters such as type of service in present load horizontal survey result, the new business services performance requirement; Step 302: whether the estimated system's available bandwidth of determining step 301 is less than the request rate in the new business services performance requirement, if change step 303 over to; Otherwise change step 308 over to.
Step 303: determine the existing controllable traffic rate adjustment scheme in sub-district.
Here, described rate adjustment scheme, require to set according to the service performance of this existing each controllable traffic in sub-district by RNC, can be set at and reduce one or several grade until being reduced to its minimum-rate of service performance requirement defined separately, also can be set at the existing service rate of part is reduced one or several grade until being reduced to its minimum-rate of service performance requirement defined separately all having controllable traffic speed.
Step 304: the load level of whole sub-district after estimating the existing controllable traffic speed of 303 determined rate adjustment scheme adjustment set by step and inserting new business.What use when estimating the load level here, is request rate in the new business services performance requirement.
Step 305: whether the cell load horizontal estimated value that determining step 304 obtains is greater than the load target value of this sub-district, if change step 306 over to; Otherwise change step 307 over to.
Wherein, the processing of above-mentioned steps 304 and step 305 also can for:
Step 304: on the set rate adjustment scheme basis of step 303, RNC calculates current system available bandwidth according to the parameters such as type of service in present load horizontal survey result, the new business services performance requirement; Step 305: whether the estimated system's available bandwidth of determining step 304 is less than the request rate in the new business services performance requirement, if change step 306 over to; Otherwise change step 307 over to.
Step 306: refuse the access request of this new business, finish access control.
Step 307: the speed of adjusting existing controllable traffic in the sub-district according to the determined rate adjustment scheme of step 303.Here, when existing professional speed is adjusted, can use the scheme of dynamic channel configuration to finish, not do qualification but specifically adopt any scheme to carry out speed adjustment the present invention, and also do not influence validity of the present invention.
Step 308: accept the access request of this new business, finish access control.
In addition, according to the actual system design needs, if system requirements access service as much as possible, then can also before step 306, further comprise step 306 ': judge that whether will all have the controllable traffic rate setting in the fixed rate adjustment scheme is separately minimum-rate, if, execution in step 306; Otherwise return step 303; Then, RNC will redefine rate adjustment scheme in step 303.Like this, system can pass through to adjust repeatedly the speed of existing controllable traffic, thereby as much as possible inserts new business.
For situation four: current area load level is that the existing service conditions of L, current area is that CSI, new business type are C, and can system at first judge and insert new business with request rate, if can, then accept this access request; Otherwise, determine the rate adjustment scheme of new business and existing controllable traffic, adjudicate then on the basis of this rate adjustment scheme and can insert new business, thereby decision is to insert new business or this access request of refusal after adjusting speed by this rate adjustment scheme.Fig. 4 is the access control one preferred embodiment handling process schematic diagram of the inventive method for situation four.As shown in Figure 4, concrete treatment step is as follows:
Type of service and request rate during step 401:RNC requires according to the service performance of current area load measure value and new business are estimated the load level of whole sub-district after the access new business.
Step 402: whether the cell load horizontal estimated value that determining step 401 obtains greater than the load target value of this sub-district, if, execution in step 403; Otherwise execution in step 411.
Step 403: system estimates the available bandwidth of current system according to the type of service in the service performance requirement of current area load measure value and new business.
Step 404: whether the estimated system's available bandwidth of determining step 403 is greater than the minimum-rate in this new business services performance requirement, if change step 405 over to; Otherwise change step 406 over to.
Step 405: the available bandwidth that step 403 is estimated is configured to the access rate of new business, execution in step 411.
Wherein, above-mentioned steps 401 to step 405 can also for:
Step 401:RNC calculates current system available bandwidth according to the parameters such as type of service in present load horizontal survey result, the new business services performance requirement; Step 402: whether the estimated system's available bandwidth of determining step 401 less than the request rate in the new business services performance requirement, if, execution in step 404; Otherwise execution in step 411; Step 404: whether the estimated system's available bandwidth of determining step 401 greater than the minimum-rate in this new business services performance requirement, if, execution in step 405; Otherwise execution in step 406; Step 405: the available bandwidth that step 401 is estimated is configured to the access rate of new business, execution in step 411.Because, estimated the available bandwidth of system in step 401, so here step 403 cancelled.
In the above treatment step, in order to guarantee existing professional speed, estimate current system available bandwidth in step 403 or step 401 earlier, judge in step 404 whether new business can insert with available bandwidth then, if new business can not insert with available bandwidth, ability execution in step 406, thus carry out next step negotiation.If system does not need at first to guarantee existing service rate, but need at first to guarantee to insert new business as far as possible, then also not execution in step 403 that is:, replace with execution in step 406 to step 405 with execution in step described in the step 402 403 or execution in step 404.
Step 406: the rate adjustment scheme of determining existing controllable traffic in sub-district and new business.
In the inventive method, the rate adjustment scheme of existing controllable traffic in described definite sub-district and new business, require to determine according to the service performance of existing each controllable traffic in this sub-district and new business by RNC, can be set at the independent controllable traffic speed that will all have and reduce one or several grade until being reduced to its minimum-rate of service performance requirement defined separately, also can be set at the independent existing controllable traffic speed of part of inciting somebody to action and reduce one or several grade until being reduced to its minimum-rate of service performance requirement defined separately, also can be set at separately new business speed is reduced one or several grade until the minimum-rate that is reduced to its service performance requirement defined, also can be set at simultaneously with all or part of existing controllable traffic, reduce one or several grade until being reduced to its minimum-rate of service performance requirement defined separately with new business speed, but the present invention does not limit for the method for concrete setting.
Step 407: the load level of estimating sub-district after 406 set rate adjustment scheme adjustment have the speed of controllable traffic and new business and insert new business set by step.
Step 408: whether the cell load horizontal estimated value that determining step 407 obtains is greater than the load target value of this sub-district, if change step 409 over to; Otherwise change step 410 over to.
Step 409: refuse this access request, finish access control.
Step 410: adjust the speed of the existing controllable traffic in sub-district according to the determined rate adjustment scheme of step 406, and for the new business speed set in the new business Configuration Adjustment Plan as access rate.
Step 411: accept this access request, finish access control.
Wherein, above-mentioned steps 406 to the processing of step 410 can also for:
Step 406: the rate adjustment scheme of determining the existing controllable traffic in sub-district; Step 407: according to the type of service in sub-district present load measured value and the new business services performance requirement, estimate the available bandwidth of system after the existing controllable traffic speed of 406 determined rate adjustment scheme adjustment set by step, and the access rate of setting new business is estimated system's available bandwidth; Step 408: whether system's estimation of available bandwidth value that determining step 407 obtains less than the minimum-rate in the new business services performance requirement, if, execution in step 409; Otherwise execution in step 410; Step 409 remains unchanged; Step 410: adjust the speed of the existing controllable traffic in sub-district according to the set rate adjustment scheme of step 406, and be that the estimated available bandwidth of new business configuration step 407 is as access rate.
In addition, according to the actual system design needs, if system requirements access service as much as possible, then can also before step 409, further comprise step 409 ', if in the rate adjustment scheme of step 406 for definite existing controllable traffic and new business, step 409 then ' be: judge that whether will all have controllable traffic and new business rate setting in the fixed rate adjustment scheme is separately minimum-rate, if, execution in step 409; Otherwise return step 406; If in step 406 for determining the rate adjustment scheme of existing controllable traffic, then step 409 ' be: judge that whether will all have the controllable traffic rate setting in the fixed rate adjustment scheme is separately minimum-rate, if, execution in step 409; Otherwise return step 406; Then, RNC will redefine rate adjustment scheme in step 406.Like this, system can pass through to adjust repeatedly the speed of existing controllable traffic, thereby is inserting new business under the condition as much as possible.
In the such scheme, if step 407 judge be load horizontal estimated value whether greater than load target value, then can also before step 409, further comprise: judge whether the minimum-rate in the new business services performance requirement is 0, if, insert new business with 0 speed, finish access control; Otherwise execution in step 409.Because 0 speed inserts new business and can not produce load, can not impact existing other business of system, therefore, for can access the new business that speed is not limited.
For situation five: current area load level is that the existing service conditions of H, current area is that CSN, new business type are NC, because current area load level is higher than load target value, and existing business in sub-district and new business are uncontrollable, so this type of access request is directly refused by system.
For situation six: current area load level is that the existing service conditions of H, current area is that CSN, new business type are C, estimate current system's available bandwidth, the access rate of setting new business is estimated system's available bandwidth, and whether whether system accept this access request less than system's available bandwidth decision according to the minimum-rate of new business.Fig. 5 is the access control one preferred embodiment handling process schematic diagram of the inventive method for situation six.As shown in Figure 5, concrete treatment step is as follows:
Step 501:RNC judges whether the minimum-rate of the service performance of new business in requiring is 0, if change step 502 over to; Otherwise change step 503 over to.
Here, because current area load level has been higher than load target value, therefore can direct estimation be 0, in rate adjustment scheme, the new business access rate is set at 0, and judge that system's available bandwidth is 0 whether less than the minimum-rate of new business to system's available bandwidth.Because the minimum-rate of new business is non-negative, then described judgement is: whether the minimum-rate of judging new business is 0.
Step 502: for new business disposes 0 speed as access rate, insert this new business, finish access control.
Step 503: refuse this access request, finish access control.
For situation seven: current area load level is that the existing service conditions of H, current area is that CSI, new business type are C, determine the rate adjustment scheme of new business and existing controllable traffic, adjudicate then on the basis of this rate adjustment scheme and can insert new business, thereby decision is to adjust speed by this rate adjustment scheme to insert new business or this access request of refusal afterwards.Fig. 6 is the access control one preferred embodiment handling process schematic diagram of the inventive method for situation seven.As shown in Figure 6, concrete treatment step is as follows:
Step 601: the rate adjustment scheme of determining existing controllable traffic in sub-district and new business.
Step 602: the load level of sub-district after estimating the speed of existing controllable traffic of 601 determined rate adjustment scheme adjustment set by step and new business and inserting new business.
Step 603: whether the cell load horizontal estimated value that determining step 602 obtains is greater than the load target value of this sub-district, if change step 604 over to; Otherwise change step 605 over to.
Step 604: refuse this access request, finish access control.
Step 605: adjust the speed of existing controllable traffic in the sub-district according to the determined rate adjustment scheme of step 601, and for the new business speed set in the new business Configuration Adjustment Plan as access rate.
Step 606: accept this access request, finish access control.
Wherein, above-mentioned steps 601 to the processing of step 605 can also for:
Step 601: the rate adjustment scheme of determining the existing controllable traffic in sub-district; Step 602: estimate the available bandwidth of system after the existing controllable traffic speed of 601 determined rate adjustment scheme adjustment set by step, the access rate of setting new business is estimated system's available bandwidth; Step 603: whether system's estimation of available bandwidth value that determining step 602 obtains less than the minimum-rate in the new business services performance requirement, if, execution in step 604; Otherwise execution in step 605; Step 604 remains unchanged; Step 605: adjust the speed of the existing controllable traffic in sub-district according to the determined rate adjustment scheme of step 601, and be that the estimated available bandwidth of new business configuration step 602 is as access rate.
In addition, according to the actual system design needs, if system requirements access service as much as possible, then can also before step 604, further comprise step 604 ', if in the rate adjustment scheme of step 601 for definite existing controllable traffic and new business, step 604 then ' be: judge that whether will all have controllable traffic and new business rate setting in the fixed rate adjustment scheme is separately minimum-rate, if, execution in step 604; Otherwise return step 601; If in step 601 for determining the rate adjustment scheme of existing controllable traffic, then step 604 ' be: judge that whether will all have the controllable traffic rate setting in the fixed rate adjustment scheme is separately minimum-rate, if, execution in step 604; Otherwise return step 601; Then, RNC will redefine rate adjustment scheme in step 601.Like this, system can pass through to adjust repeatedly the speed of existing controllable traffic, thereby is inserting new business under the condition as much as possible.
In the such scheme, if step 603 judge be load horizontal estimated value whether greater than load target value, then can also before step 604, further comprise: judge whether the minimum-rate in the new business services performance requirement is 0, if, insert new business with 0 speed, finish access control; Otherwise execution in step 604.
For situation eight: current area load level is that the existing service conditions of H, current area is that CSI, new business type are NC, system determines existing controllable traffic rate adjustment scheme, reconvict and on the basis of this rate adjustment scheme, to insert new business, thereby decision is to adjust speed by this rate adjustment scheme to insert new business or this access request of refusal afterwards.Fig. 7 is the access control one preferred embodiment handling process schematic diagram of the inventive method for situation eight.As shown in Figure 7, concrete treatment step is as follows:
Step 701: the rate adjustment scheme of determining the existing controllable traffic in sub-district.
Step 702: the load level of sub-district after estimating the speed of the existing controllable traffic of 701 determined rate adjustment scheme adjustment set by step and inserting new business.What use when estimating the load level here, is request rate in the new business services performance requirement.
Step 703: whether the cell load horizontal estimated value that determining step 702 obtains is greater than the load target value of this sub-district, if change step 704 over to; Otherwise change step 705 over to.
Wherein, the processing of above-mentioned steps 702, step 703 can also for:
Step 702: the available bandwidth of estimating system after the existing controllable traffic speed of 701 determined rate adjustment scheme adjustment set by step; Step 703: whether system's estimation of available bandwidth value that determining step 702 obtains less than the request rate in the new business services performance requirement, if, execution in step 704; Otherwise execution in step 705.
Step 704: refuse this access request, finish access control.
Step 705: the speed of adjusting existing controllable traffic in the sub-district according to the determined rate adjustment scheme of step 701.
Step 706: accept this access request, finish access control.
In addition, according to the actual system design needs, if system requirements access service as much as possible, then can also before step 704, further comprise step 704 ': judge that whether will all have the controllable traffic rate setting in the fixed rate adjustment scheme is separately minimum-rate, if, execution in step 704; Otherwise return step 701; Then, RNC will redefine rate adjustment scheme in step 701.Like this, system can pass through to adjust repeatedly the speed of existing controllable traffic, thereby is inserting new business under the condition as much as possible.
In the WCDMA system, when initiating new calling or application in a new sub-district, a mobile subscriber switches, perhaps in an existing calling procedure, increase a new business, perhaps existing business is carried out channel and reshuffle the described access control of Shi Junke execution the inventive method.Here, be that new business inserts with initiating new calling in the new sub-district and in an existing calling procedure, increasing a new service definition; To apply for switching being defined as switching a new sub-district, and switching will be divided into switching and alien frequencies switch two classes frequently; To carry out channel to existing business reshuffles and is defined as channel and reshuffles; Then the access request of new business can be divided into: new business inserts, reshuffles four classes with switching frequently, alien frequencies switching and channel.When carrying out access control, the uplink and downlink link carries out access control respectively in addition, has only when the uplink and downlink link and all adjudicates can accept the access request time, inserts new business thereby system just accepts this access request.The foregoing description can be applied to the access control that new business access, alien frequencies switching and channel are reshuffled the upstream or downstream link of three kinds of access requests.
When the inventive method is applied to together the down link access control of switching frequently, the scheme and the such scheme that adopt are basic identical, because, can not directly reduce its original service rate with the user of switching frequently, need reshuffling of through-rate to finish the adjustment of speed, therefore need and to replace with for new business disposes access rate: for new business proposes the suggestion that speed is reshuffled, and refuse the access request of this new business, after reconfiguring speed by this new business by this suggestion, resubmit the access request with this speed that reconfigures again.
