Description
Technical field
The present invention relates to wireless communication technology, particularly improve the transport layer resource allocation management technology of wireless communication system the reliability of the call completing rate of business and transmission.
Background technology
Wideband Code Division Multiple Access (WCDMA) (Wideband Code Division Multiple Access is called for short " WCDMA ") mobile communication system is a kind of wireless access technology of 3-G (Generation Three mobile communication system) air interface part.Compare with second generation digital mobile communication system with first generation simulation mobile communication, the main feature of WCDMA is that mobile multi-media service can be provided.On system configuration and function, the WCDMA system can be divided into Radio Access Network (Radio Access Network is called for short " RAN ") and core net (Core Net is called for short " CN ").RAN is used to handle all and wireless function associated, and CN is responsible for then handling that all voice calls in the WCDMA system are connected with data and the exchange and the route of external network.Mainly comprise two category nodes among the RAN: base station and radio network controller (Radio Network Controller is called for short " RNC ").Wherein, the transmitting-receiving and the bottom layer treatment of wireless signal is responsible in the base station, otherwise and the signal that will from air interface, receive be transferred to RNC or.RNC is responsible for the interface of wireless access network and core net, also is responsible for the management of on-air radio transfer resource.
RNC mainly finishes wireless transmission resources management and controlled function, and the interface of RNC by standard is connected with the base station with CN respectively and is connected.Concerning RNC, its system can be divided into transfer resource part and control section.Transfer resource partly is made up of a plurality of transfer resource processing units, and each transfer resource processing unit is the system transmissions resource in order to the transmission data.The RNC control section is means by controlling the transport layer distribution of transmission resource situation that sub-district or user use with transport layer transmission resource management, allocation strategy, reaches the try one's best purpose of load sharing user telephone traffic of transport layer transfer resource.The transport layer transfer resource is load sharing user telephone traffic to greatest extent, avoid part transport layer transfer resource to be overused and the idle situation of other transfer resources, to make system insert the user to greatest extent, and guarantee that as far as possible inserting the user uses professional reliability, be the key factor of system safety, efficient operation.Therefore, transport layer transmission resource management allocation strategy is that extremely necessity also is extremely important to the system of a stable operation.
Three kinds of schemes that realize the transport layer transmission resource management are arranged in the prior art.
First method is to be the transport layer transfer resource allocation strategy of foundation with the number of users.The number of users that has inserted in the transfer resource processing unit of this scheme by statistics transport layer transfer resource place, obtain a transfer resource processing unit that current access customer number order is minimum, and be made as its priority the highest, when next customer requirements connecting system, preferentially be that it distributes the transport layer transfer resource on this transfer resource processing unit.Make this scheme easy operating and maintenance owing to objects of statistics is simple and clear, the allocation strategy algorithm is also simple, can play a role to transport layer transfer resource load sharing telephone traffic.
Second method is that the transmission resource consumption data with transport layer transfer resource real-time report are the transfer resource allocation strategy of foundation.The actual transmissions resource consumption data that this scheme reports by writing down each transfer resource processing unit, the priority of the processing unit that actual consumption is minimum is made as the highest, when next customer requirements connecting system, preferentially be that it distributes the transport layer transfer resource on this transfer resource processing unit.This allocation strategy is a foundation with real transmission resource consumption situation, can make control section control the consumption situation of transfer resource part in real time, transfer resource is distributed adjust.
The third method is that the transfer resource processing unit consumption figures that goes out with the discreet value of business accumulative total is the transfer resource allocation strategy of foundation.This scheme writes down distributable concrete transport layer transfer resource and disposal ability total amount in the current transfer resource part.When a sub-district foundation or a customer requirements access, by analyzing its transport layer transfer resource that need use and disposal ability data, if the transfer resource processing unit of current transmission layer transmission resource consumption and disposal ability consumes least can bear new business and insert the transport layer transmission resource consumption of bringing, then the concrete transfer resource of transport layer in this transfer resource processing unit is distributed to the sub-district or the user of current foundation, upgraded the record that concrete transport layer transfer resource of current transfer resource part and disposal ability consume then.Otherwise, then select transport layer transmission resource consumption and disposal ability consumption figures time little transfer resource processing unit to carry out the transport layer transfer resource and distribute, until no selectable process unit, then refuse the access of this business.
Need to prove that the transmission resource consumption discreet value is the maximum that this business of obtaining by statistical method can consumable transport layer transfer resource.This allocation strategy adopts the mode of pre-estimating transmission resource consumption to the business that inserts, estimate the transmission resource consumption of maximum cost with the maximum rate situation, but can guarantee professional transfer resource processing unit operate as normal when transmitting with maximum rate, and the load sharing of accomplishing big rate business that can be more accurate, in case system loading reaches the upper limit, the business of also can refusing guarantees the normal operation of access service and system.
In actual applications, there is following problem in such scheme:
The problem of first method is not consider to set up between the user professional otherness, brings basic error on the algorithm for thus the load sharing of transport layer transfer resource, and probably causes big rate business to converge to a transfer resource processing unit getting on.The service rate of supporting among the WCDMA is very abundant, bandwidth range is bigger, maximum rate can reach 384K/bps, minimum-rate but can be 1K/bps, therefore the speed difference between the business increases than second generation mobile communcations system greatly, professional speed difference is apart from having brought professional difference to transport layer transfer resource use amount, also caused the difference of using the transport layer transfer resource between the user, this difference is on the maximum rate difference of business, be very large, to the stage that definitely can not ignore, therefore transport layer transfer resource allocation strategy as above exists big defective.
The problem of second method is to control effectively big rate business load sharing to each transfer resource carrying.With the Packet data service is example, when business is set up the transmission of laggard line data, the maximum rate of registering during not always with service access carries out transfer of data, when the bigger business of access rate during with less rate transmissioning data, having triggered the transfer resource processing unit reports current transmission resource consumption sampling, the data that report have just reflected the transmission resource consumption situation under the present rate, and numerical value is less.Control section with this transfer resource processing unit priority establish higher, if insert the business of big speed again, in case the business that these speed are bigger is transmitted data with maximum rate, will cause the collapse of transfer resource processing unit, increased the unsteadiness of system's operation.
The problem of the third method then is to reckon without for existing big gap between service access reservation transfer resource and the professional actual transmissions institute consume transmission resources, causes inefficiency problem such as the system transmissions wasting of resources thus.The transfer resource static allocation that this method just needs when causing system that professional maximum rate is transmitted uses for this business, as long as this professional existence, no matter it is with which kind of speed rates, these transfer resources all are that it is monopolized, even big rate business is with very little speed rates, the transmission resource consumption of current transfer resource processing unit reality is very little, but the upper limit owing to the consumption of the consumption figures of estimating Danone power, also just no longer allow other service accesses, cause the waste of system transmissions resource, influence call completing rate, reduced the efficient of system's access service.
Summary of the invention
In view of this, main purpose of the present invention is to provide a kind of transport layer transfer resource distribution method, make system transmissions layer transfer resource can share each traffic carrying capacity more efficiently, thereby improved the utilance of system transmissions resource, guarantee professional call completion ratio, and strengthened the stability of service operation in the system.
For achieving the above object, the invention provides a kind of transport layer transfer resource distribution method, comprise following steps:
The transfer resource processing unit that the current transmission resource consumption actual value of A RNC control section surpasses the warning line that sets in advance is set to forbid distribution state;
B obtains the transmission resource consumption discreet value of transfer resource processing unit; When sub-district foundation or business need access, but in being in the transfer resource processing unit of distribution state, select the transfer resource processing unit of the aggregate-value minimum of transmission resource consumption discreet value, for setting up or service access distribution transport layer transfer resource described sub-district.
Wherein, described steps A comprises following substep:
Whether the current transmission resource consumption actual value of the described transfer resource processing unit detection of A1 self surpasses the warning line that sets in advance, if then report the overload alarm to described control section;
Described control section response of A2 and the alarm of record overload, described transfer resource processing unit is set to forbid distribution state.
Described step B also comprises following substep:
The selected transfer resource processing unit of B1 is that described sub-district is set up or service access is distributed the transport layer transfer resource;
B2 judges that described transport layer transfer resource distributes whether success, if, execution in step B3 then; Otherwise, execution in step B4;
B3 adds up described sub-district or professional transmission resource consumption discreet value into the aggregate-value of the transmission resource consumption discreet value of this transfer resource processing unit;
But B4 judges whether to be in addition other transfer resource processing units of distribution state, if then select the aggregate-value time little transfer resource processing unit of transmission resource consumption discreet value and execution in step B1; Otherwise, refuse described sub-district and set up or service access.
Described transmission resource consumption discreet value is the maximum that this business of obtaining by statistical method can consumable transport layer transfer resource.
Described warning line can be arranged on this transfer resource processing unit the transfer resource total amount 75% to 85%.
By relatively finding, technical scheme difference with the prior art of the present invention is, abandoned on the one hand in the prior art scheme with the number of users is according to being that the user inserts the notion of distributing the transport layer transfer resource, and do not re-use static transfer resource and can distribute total amount to be used as the upper limit judgement of service access, transfer the transport layer transmission resource management strategy that uses professional transmission resource consumption discreet value to combine with the actual transmissions resource consumption; Whether reach warning line by dynamic monitoring transfer resource processing unit transmission resource consumption numerical value on the other hand and provide effective guarantee for system normally moves, utilize the actual overload alarm that reports of transfer resource processing unit as the assurance that system runs well, solved the problem of the low and systematic jitters of access efficiency that existing conventional art may cause.
Difference on this technical scheme, brought comparatively significantly beneficial effect, the present invention refuses access service by transfer resource processing unit dynamic monitoring transmission resource consumption situation after the transfer resource load reaches warning line, thereby has guaranteed the stable of system's operation effectively.The setting of the warning line by leaving certain transfer resource surplus has guaranteed in the transfer resource processing unit with the professional of maximum rate operation in case can normally operation in the general probability of statistics with the maximum rate operation.The stability of whole system operation can be improved like this, the efficient utilization of system transmissions resource can be guaranteed again.
In a word, the invention provides the reliable and efficient transmission resource management allocative decision of moving of a safeguards system.

Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with accompanying drawing.
Generally speaking, the present invention program carries out dynamic monitoring by the transfer resource situation to the transport layer actual consumption, and in conjunction with transfer resource discreet value thought, management system transport layer transfer resource distributes efficiently.
Specifically, the present invention program dynamically writes down distributable concrete transport layer transfer resource of transfer resource part and disposal ability total amount, and when the transfer resource processing unit arrives the load warning line to control section report and alarm information, professional again to the transfer resource processing unit distribution of alarm to forbid, the assurance system runs well.Simultaneously, estimate thought by transfer resource and distribute the transport layer transfer resource efficiently for each access service, the required transport layer transfer resource of distribution service on the transfer resource processing unit of the aggregate-value minimum of overload alarm and transmission resource consumption discreet value not.
Fig. 1 shows the service access transfer resource distribution structure schematic diagram of one embodiment of the present of invention;
As shown in Figure 1, radio network controller (Radio Network Controller is called for short " RNC ") 20 mainly is divided into two parts: transfer resource part 21 and control section 25.Professional first 10 is that a kind of transmission rate is the data service of 384kbps, and professional second 11 then is telephone service.Wherein, transfer resource part 21 is made up of a plurality of transfer resource processing units, as transfer resource processing unit A22, transfer resource processing unit B23 among Fig. 1 and transfer resource processing unit C24 three parts, these transfer resource processing units are the system transmissions resources in order to the transmission data.Control section 25 is to be that means are being controlled the transfer resource that service access is used with transmission resource management and allocation strategy.The transfer resource load total amount of each transfer resource processing unit is 100, and in the present embodiment, its warning line is 80.The warning line that need to prove the transfer resource processing unit rule of thumb is provided with, and generally can be arranged in 75% to 85% the scope of transfer resource processing unit transfer resource total amount.
When professional first 10 and the 11 request accesses of professional second, the RNC20 dynamic monitoring is 76 to the load of current transfer resource processing unit A22, and the load of transfer resource processing unit B23 is 77, and the load of transfer resource processing unit C24 is 81.According to the principle of the invention, the load of transfer resource processing unit C24 has surpassed the warning line numerical value that present embodiment is provided with, therefore transfer resource processing unit C24 needs to report the overload alarm to control section 25 immediately, then control section 25 writes down these warning information, and forbids that this alarm transfer resource processing unit C24 inserts any business.
Subsequently, in transfer resource processing unit A22 that does not have alarm and transfer resource processing unit B23, by the traffic assignments transfer resource of transfer resource processing unit of analyzing the aggregate-value minimum of selecting the transmission resource consumption discreet value for asking to insert.If this transfer resource processing unit is successfully distributed transfer resource, then again the resource consumption discreet value of business is added up into this transfer resource processing unit.Otherwise, but need further judge whether to be in addition all the other transfer resource processing units of distribution state, if but there are not all the other transfer resource processing units of distribution state, the request of then directly refusing this business inserts.If but all the other transfer resource processing units that are in distribution state are still arranged, then select the aggregate-value time little transfer resource processing unit of transmission resource consumption discreet value to adjudicate access again, at this simple and clear just repeated description no longer for article.
For professional first 10, its transmission resource consumption discreet value is 4, the aggregate-value minimum of transmission resource consumption discreet value is 76, principle according to the present invention program, if corresponding transfer resource processing unit A22 is professional first 10 successful allocation of transmission resources, then need resource consumption discreet value 4 with professional first 10 to add up among this transfer resource processing unit A22.And for professional second 11, its transmission resource consumption discreet value is 0.2, minimum value to the aggregate-value of transmission resource consumption discreet value that should be professional is 76, equally, if corresponding transfer resource processing unit A22 is professional second 11 successful allocation of transmission resources, then need again resource consumption discreet value 0.2 with professional second 11 to add up among this transfer resource processing unit A22.
Describe the idiographic flow that monitors the system handles operation when having reached warning line of the current resource consumption value of transfer resource processing unit according to an embodiment of the invention in detail below with reference to Fig. 2.
At first, in step 200, transfer resource processing unit C24 monitors current transmission resource consumption value 81 and has reached warning line.So, enter step 205 subsequently.
In step 205, transfer resource processing unit C24 reports the overload warning information to control section 25.In step 210 subsequently, control section 25 responses and the alarm of record overload, and the transfer resource processing unit C24 that this transmission resource consumption value reaches warning line is set to forbid distribution state, do not allow this transfer resource processing unit C24 to insert any business.
Refer again to Fig. 3 below and describe the service access processing of request flow process that monitors a time according to an embodiment of the invention in detail.
At first in step 220, system monitoring is to there being business need to insert.Suppose that system monitoring subsequently, enters step 230 to there being professional second 11 requests to insert at this moment.
In step 230, be that access service distributes transfer resource but in being in the transfer resource processing unit of distribution state, select the transfer resource processing unit of the discreet value minimum of transmission resource consumption aggregate-value.Be in the transfer resource processing unit of forbidding distribution state for those and then do not need to consider to insert any business.Next, the step 260 that improves.
In step 260, consider that the transfer resource processing unit not necessarily can both be allocated successfully a such fact when being access service distribution transfer resource at every turn, need this transfer resource processing unit of judgement be whether traffic assignments transport layer resource is successful.If this transfer resource processing unit successfully is the traffic assignments transfer resource, then in step 270 subsequently, the resource consumption discreet value of business is added up into this transfer resource processing unit.If this transfer resource processing unit successfully is not the good transfer resource of traffic assignments, then this transfer resource processing unit can't insert the business that this request inserts, so, enter step 280 subsequently.
In step 280, but system detects all the other transfer resource processing units that whether are in distribution state in addition, but, then enter the directly request access of this business of refusal in the step 300 if in this RNC21, be not in the transfer resource processing unit of distribution state.But because except the processing unit of the aggregate-value minimum of the transmission resource consumption discreet value that is in distribution state in abovementioned steps, chosen among the RNC21 all the other whole transfer resource processing units all be in and forbid distribution state, and but this processing unit of aggregate-value minimum that is in the transmission resource consumption discreet value of distribution state can't be that this access service distributes transfer resource, so the access request of this business can only be refused by system.And on the other hand, if but system detects all the other transfer resource processing units that are in distribution state in RNC21 in addition, then return in the step 230 and again the transfer resource processing unit is adjudicated access, at this simple and clear just repeated description no longer for article.In a word, but by select the transfer resource processing unit of the aggregate-value minimum of transmission resource consumption discreet value in being in all the other transfer resource processing units of distribution state is the service access allocation of transmission resources, finally refuses the access requirement of this business until there not being optional transfer resource processing unit.
Though by reference some preferred embodiment of the present invention, the present invention is illustrated and describes, but those of ordinary skill in the art should be understood that, can do various changes to it in the form and details, and the spirit and scope of the present invention that do not depart from appended claims and limited.
