Abstract
The present invention discloses a resource planning method in a communication system. The method is characterized in that a part of system resources is set into reserved resources reserved for high-end users for use, and the rest system resources are used as the shared resources of the high-end user and low-end users. When the user applies network access, resources are firstly assigned from the shared resources for the user, and services are provided for the user. If the shared resources are finished to be assigned, whether the user is the high-end user is required to be judged. If true, resources are assigned for the high-end user from the reserved resources, and services are provided for the user. When the shared resources are finished to be assigned, and no resource to be assigned to the high-end user exists in the reserved resources, low priority level users are chosen for resource occupation, and occupied resources are used to serve the high-end user. The scheme is characterized in that the occurrence of the resource occupation can be prevented or reduced to some extent. Meanwhile, the problem that priority services are provided for high priority level users by the system can be effectively solved.
Description
Technical field
The present invention relates to the distribution and the management method of resource in the communication system.
Background technology
In present communication system, in the especially various mobile communication system, in some cases traffic peak can appear, and at this moment, the total resources that user applies is used is greater than available resources total amount in the system.The appearance of this situation will cause a part of user can't connecting system, perhaps can't obtain satisfied service behind the connecting system, and promptly the service quality of its traffic application (QOS) is not being met.Usually, for Virtual network operator, when traffic peak occurring, often need the quality of service requirement that guarantees the network insertion of the specific user in its customer group fully or as much as possible or satisfy the accessed network traffic.For this reason, need realize the demand by planning and management to system resource.Satisfy the most general way of the demand, must refuse some general user's access request exactly or interrupt its service or be reduced to the service quality that the general user provides.For example, the most general way that realizes above-mentioned purpose is to adopt system resource to seize method, and this method realizes by the use of system resource is monitored.When finding that system resource is not enough, the not low user's of interrupt priority level business makes it discharge resource by force, and the user higher for priority level uses.This method is reasonably from the angle of the level of resources utilization, high benefit principle management and using system resource that it can use according to resource.But in the network operation of reality, no matter for operator or user, the business of interrupting a user is than the delay of network insertion or wait for and more make us being difficult to accepting, so system always avoids the use of these means as far as possible in the reality.
One as said method substitutes, and also can adopt the method based on priority queueing to solve the problem that system resource is used.The essence of this method is: when system resource is not enough, the applicant waits in line, concrete queuing is finished successively according to user's priority, the user's that priority level is high business comes head of the queue all the time, the user that priority level is identical lined up successively by the application time, like this, in case system resource has the free time, other user of high priority will preferentially obtain service.
In above-mentioned two kinds of methods, the harm of the maximum of first method is the reduction of service credit worthiness, and side effect is bigger; Second method is for the user, the queue waiting time that can tolerate when inserting is shorter usually, especially when the application voice service, its general selection is to make a call again, and in the so short time, the probability that obtains resource owing to other user's traffics end is not high yet, and therefore this scheme in actual applications neither be very effective.
Summary of the invention
The object of the present invention is to provide MRP method in a kind of communication system, use this method effectively resolution system provide the problem of Priority Service as high-priority users, avoid or reduce the generation of resource race to control simultaneously.
For achieving the above object, MRP method in the communication system provided by the invention comprises:
The system resource quantity that setting keeps for high-priority users to use is with the shared resource of all the other system resources as high-priority users and low priority user;
When the user applies network insertion, at first from shared resource, provide service for user resource allocation and for the user, if shared resource assigns, judge then whether the user is high-priority users, if, from reserved resource,, otherwise refuse the network insertion of this low priority user for this high-priority users Resources allocation and for the user provides service.
When shared resource assigns, and during the resource that does not have in the reserved resource to distribute for high-priority users, select other user of low priority to carry out resource race to control, use the resource of seizing to be the high-priority users service.
Before selecting other user of low priority to carry out resource race to control, the high-priority users of log on access is sent into the high-priority users formation rank, when queuing time surpasses the threshold value of regulation, select other user of low priority again and carry out resource race to control.
The threshold value that does not surpass regulation when the queuing time of high-priority users, and when there have been the shared resource that can distribute for high-priority users or reserved resource in system, for this high-priority users Resources allocation and for it provides service, remove the queuing timer of this high-priority users simultaneously.
Before the network insertion of refusal low priority user, this low priority user is sent into the low priority user formation rank, when queuing time surpasses the threshold value of regulation, refuse the network insertion of this low priority user again.
In addition, the present invention can determine the system resource of keeping for high-priority users to use according to the ratio of the number of the number of high-priority users in the system and low priority user; Also can dynamically adjust the system resource quantity of keeping for high-priority users to use according to the historical occupied information of system resource; If adopt the latter, then adopt following method dynamically to adjust the system resource quantity of keeping for high-priority users to use: if the behavior of shared resource took place to seize in the stipulated time before the current time, then increase the system resource quantity of keeping for high-priority users to use, if the behavior of low priority user network insertion failure or queuing took place in the stipulated time before the current time, and reserved resource is not used or utilization rate is lower than the threshold value of regulation, then reduces the system resource quantity of keeping for high-priority users to use.
Whether whether when the system resource quantity of high-priority users use is kept in increase, at first checking has idling-resource in the shared resource, if having, be empty in the reexamine low priority Subscriber Queue, if be empty, is reserved resource with idle shared resource setting.
The present invention also is provided with the amount threshold that increases reserved resource, when idle shared resource setting is reserved resource, is provided with in the scope of this threshold value.
Because the present invention adopts reservation system resource to high-priority users is set, and with the method for all the other system resources as the shared resource of high-priority users and low priority user, like this, when the user applies network insertion, can be at first from shared resource, provide service for user resource allocation and for the user, if shared resource assigns, and this user is when being high-priority users, then can avoid or reduce the generation of resource race to control so to a certain extent for this high-priority users Resources allocation and for the user provides service from reserved resource; Simultaneously, when shared resource assigns, and during the resource that does not have in the reserved resource to distribute for high-priority users, select other user of low priority to carry out resource race to control again, use the resource of seizing to be the high-priority users service, thereby effective resolution system provide the problem of Priority Service for high-priority users.

Embodiment
In the reality of communication system, occurring high-priority users when traffic peak occurring inevitably seizes the system resource that low priority user is taking, because the service disconnection that too much resource race to control causes more makes us being difficult to receiving than temporarily not inserting, so needs to avoid the generation of this phenomenon in the reality as far as possible.Based on this, essence of the present invention is, by planning management to system resource, keep for high-priority users to use the system resource of some, and all the other resources are as the shared resource of high and low priority users, to guarantee providing service by reserved resource for high-priority users when system resource is not enough, avoid the resource of low priority user is seized as far as possible, also guarantee to provide simultaneously the quality of service for high-priority users.
Specific implementation of the present invention is such: the system resource quantity of keeping for high-priority users to use at first is set, with the shared resource of all the other system resources as high-priority users and low priority user.Concrete reservation system value can be configured by the system network management center, when initial, the quantity of reserved resource can rule of thumb be provided with, also can be according to determining with the ratio value of the number of signatory high-priority users number of Virtual network operator and low priority user.10% reserved resource for example can be set give high-priority users, 90% remaining resource is a shared resource, for high priority and low priority user are owned together.Like this, under normal circumstances, when the user applies network insertion, at first from shared resource, provide service for user resource allocation and for the user, it is Resources allocation in the shared resource pond only under the normal condition, if but shared resource assigns, for the new resource bid that proposes owing to new subscriber access system afterwards, to judge then whether the user is high-priority users, if, from reserved resource for this high-priority users Resources allocation and for the user provides service, if the then network insertion of this low priority user of low priority user.But also has such situation in the reality, when being the high-priority users access, shared resource assigns, and do not have in the reserved resource to be the resource of high-priority users distribution, at this moment, be the service quality that the assurance system provides for high-priority users, select other user of low priority to carry out resource race to control, use the resource of seizing to be the high-priority users service then.
In said method, in order further to reduce the number of times that the shared resource race to control of low priority user is taken place, when the other user applies resource of high priority and reserved resource when also not having idling-resource can consider to allow it participate in priority level queuing earlier.When its queuing time surpasses a certain threshold value (for example 5 seconds) and still do not wait until the resource of distributing to it, come into effect resource race to control again to the low side low priority user.Therefore, also to set in advance the queue queue of high-priority users, and the threshold value of waiting in line that high-priority users is set, like this, when the high-priority users connecting system, and system does not have to distribute to the resource of high-priority users, then before selecting other user of low priority to carry out resource race to control, the high-priority users of log on access is sent into the formation of formation high-priority users ranks, start the queuing timer of this high-priority users simultaneously, when learning that by timer queuing time surpasses the threshold value of regulation, select other user of low priority again and carry out resource race to control.If when the queuing time of high-priority users does not surpass the threshold value of regulation, when there have been the shared resource that can distribute for high-priority users or reserved resource in system, then, remove the queuing timer of this high-priority users simultaneously for this high-priority users Resources allocation and for it provides service.
In like manner, more perfect for making systemic-function, when other user access network of low priority,, also can consider to allow it participate in priority queueing rather than refusal immediately if No Assets can distribute.Therefore, for realizing aforesaid operations, also to set in advance the queue queue of low side low priority user, and the threshold value of waiting in line that the low side low priority user is set, like this, before the network insertion of refusal low priority user, this low priority user is sent into the low priority user formation ranks, start the queuing timer of this low priority user simultaneously, when queuing time surpasses the threshold value of regulation, refuse the network insertion of this low priority user again.Certainly, if when the queuing time of low priority user does not surpass the threshold value of regulation, system has just had and can then for this low priority user Resources allocation and for it provides service, remove the queuing timer of this low priority user simultaneously for the shared resource of low priority user distribution.
In specific implementation process of the present invention, since system resource take or operating position in dynamic change, only rule of thumb or with the ratio value of the number of signatory high-priority users number of Virtual network operator and low priority user determine that it may be irrational keeping for the resource quantity of high-priority users, because the variation of the difficult usually system resource of reflection comprehensively of the static like this numerical value that is provided with user mode, the also situation that may cause system resource not to be fully utilized.Therefore, the present invention also dynamically adjusts the system resource quantity of keeping for high-priority users to use according to the historical occupied information of system resource, promptly according to historical statistics information, determine reliable traffic model, on this basis, dynamically adjust for high-priority users reserved resource quantity according to the occupation condition of last period.Concrete dynamic adjusting method is such: if the behavior of shared resource took place to seize in the stipulated time before the current time, show that amount of resources reserved is less, can consider increases the system resource quantity of keeping for high-priority users to use in the next time period, for example the shared region resource that discharges is drawn immediately and makes reserved resource; If the behavior of low priority user network insertion failure or queuing took place in the stipulated time before the current time, and reserved resource is not used or utilization rate is lower than the threshold value of regulation, illustrate that then amount of resources reserved is bigger than normal, can consider to reduce the system resource quantity of keeping for high-priority users to use.
Keep in the system resource quantity process of high-priority users use in concrete increase, at first check whether idling-resource is arranged in the shared resource, if have, illustrate to have and to supply the reserved resource of increase, at this moment, whether be empty in the reexamine low priority Subscriber Queue, if be empty, illustrating that shared resource can be used as reserved resource, is reserved resource with idle shared resource setting therefore.For the quantity regulating that makes reserved resource the minimum that influences to system, the amount threshold that increases reserved resource can be set in the reality, when idle shared resource setting is reserved resource, in the scope of this threshold value, is provided with or increases.
In like manner, keep in the system resource quantity process of high-priority users use in concrete minimizing, at first check whether idling-resource is arranged in the reserved resource, if have, illustrate to have to supply the reserved resource of minimizing, at this moment, whether reexamine in the high-priority users formation is empty, if be empty, illustrate that shared resource can be used as resources shared, therefore idle reserved resource is set to shared resource.Certainly, when reducing reserved resource, the amount threshold that just reduces can be set also, when reducing dynamically to adjust reserved resource quantity to the influence of system.
In addition,, can consider to adopt the short time period, as consider the per 30 minutes pre-allowances of adjusting first resource in order to make resource reservation more accurate.
The present invention is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the embodiment flow chart of the method for the invention.According to Fig. 1, when the user carries out network insertion and during the application system resource in step 1, system checks in step 2 whether idle resource is arranged in the shared resource, if have, be this user resource allocation then in step 3, provide service for this user simultaneously, if there is not idling-resource, then judge in step 4 whether this user is high-priority users, if not, in network insertion request this time of step 5 refusing user's or do other processing; If high-priority users, then continue to judge whether idling-resource is arranged in the reserved resource, if having, be this user resource allocation from shared resource, and provide service for this user in step 7; If not can be the resource that this user distributes in the shared resource yet, then this user is delivered to the high-priority users formation queuing that sets in advance in step 8, and, the user is handled accordingly according to the state of timer in step 9 at last for this user is provided with timer.The concrete operations of step 9 are such: before described timer expiry, if this user's timer is then removed in the access that the user initiatively exits network; If before described timer expiry, waited for idling-resource, then this user resource allocation, for this user provides service, and remove timer; If described timer expiry then selects other user of low priority to carry out resource race to control from shared resource.
In the described embodiment running of Fig. 1, also to carry out the self adaptation adjustment to giving high-priority users reserved resource quantity, detailed process is with reference to figure 2.At first a T minute timer is set in step 21, check each statistical value relevant in step 22 then with the system resource operating position, as the high-priority users of the current access of network and the number of low priority user, reserved resource and shared resource utilize situation etc., whether resource race to control to low priority user then in judging in the past T minute, step 23 has taken place, if the resource race to control phenomenon has taken place, the reserved resource deficiency is described, then a mark J is set in step 25, divide K reserved resource of increase in the clock time with indication at next T, described K value can rule of thumb be worth setting, also can dynamically adjust according to the system resource utilization situation.If in step 23 is judged in the past T minute the resource race to control phenomenon does not take place, the quantity that reserved resource be described does not need to increase at present to be adjusted, and continues judgement but whether need to reduce to adjust then also will do.Therefore whether the phenomenon that other user of low priority is rejected network insertion in continuing to judge in the past T minute, step 24 has taken place, if above-mentioned phenomenon did not take place, the quantity that reserved resource is described is appropriate, therefore do not carry out the adjustment operation of resource in step 26, but proceed other system operation; If the phenomenon that low priority other user is rejected network insertion took place in T in the past minute, the shared resource deficiency is described, can't determine whether the part of reserved resource can be converted into shared resource when at this moment, also will be in step 27 continue to be judged in the past T minute the peak use rate of reserved resource whether less than pre-set threshold, if less than, illustrate that reserved resource quantity is too much, can transform a part as shared resource, therefore in step 28, according to predefined conversion values, the part reserved resource is converted into shared resource; Otherwise illustrate that reserved resource quantity is appropriate, can not transform, therefore do not carry out the adjustment operation of resource, but proceed other system operation in step 29.
In the adjustment process of above-mentioned reserved resource resource, K reserved resource of the described increase of step 25 realized according to following process, with reference to figure 3: at first system will not discharged by the shared resource of CU in step 251, and put in order, check in step 252 whether the low priority user formation has the user of queuing then, if having, then at the user resource allocation of step 254 for queuing, and, carry out step 257 then for it provides service; If check that in step 252 the low priority user formation does not have the user of queuing, then whether be provided with the mark J that enlarges reserved resource in step 253 check system, if do not have, illustrating does not need to adjust reserved resource, finish adjustment process in step 256, otherwise be converted into reserved resource according to predefined strategy at step 255 shared resource that this is idle; Then check in step 257 whether the adjustment amount of reserved resource reaches the requirement of predefined K value,, finish adjustment process, and remove the mark J that increases reserved resource in step 259 if reach; Otherwise also will judge whether T minute timer be overtime through step 258, if overtime, also execution in step 259, if not overtime, then return the adjustment that step 251 proceeds to increase reserved resource.
In a word,, can avoid or reduce the generation of resource race to control phenomenon to greatest extent, the service quality that provides for high-priority users is provided by MRP method of the present invention.
