- the dr as the subscript indicates the rate
- d1 indicates the delay
- p1r indicates the packet loss rate

- the weights corresponding to the above three QoS parameters are respectively passed: It is shown that, in combination with the description of step 102 of the embodiment, the QoS metric value U i (t) of the service i can be obtained by the following formula (0).
- the weights of all the QoS parameters of a service are 1 and, for example, in this embodiment:
- the required degree of the QoS parameter is positively correlated with the weight corresponding to the QoS parameter, that is, when the to-be-scheduled service has a high demand for any one of the QoS characteristics, the weight corresponding to the QoS characteristic parameter The weight corresponding to the remaining QoS parameters is larger.

- the delay parameter, the error packet rate parameter, the packet loss rate parameter, the delay jitter parameter, and the like are represented, and different service characteristics are distinguished by describing the parameters.
- the voice service in the real-time service requires a low transmission delay, which requires a high priority to reduce the scheduling delay when scheduling the service, and a low delay requirement for the video stream service in the non-real-time service.
- the rate requirement is high, then allocate more bandwidth when scheduling the service to ensure the data rate.
- the different proportions of the above various QoS parameters indicate different services, that is, the weights of these parameters can be used for service differentiation.
- the weights of these parameters can be used for service differentiation.
- the delay requirement is high, so the weight can be increased to ensure the priority scheduling right of the service.
- the determination of these weights is based on the characteristics of the service, and can also be determined based on the simulation service. Once the business is determined, its weight is determined and does not change over time.
- the QoS parameter included in the to-be-scheduled service may have one or several types, and correspondingly, the number of QoS parameters is equal.

- the technical solution provided by the embodiment of the present invention can calculate a more accurate QoS scheduling value of the service, thereby accurately implementing service scheduling and improving the success rate of service implementation.
- the existing QoS parameters indicates that, of course, when there is a new QoS requirement for the to-be-scheduled service, new QoS parameters, parameter values corresponding to the new QoS parameters, and weights corresponding to the new QoS parameters appear correspondingly, and for the sake of simplicity,
- the above three objects respectively pass: a new QoS parameter, a new parameter value, and a new weight description.
- a simplified description of the adaptation of different objects is performed. If there is a coincident part, it does not mean that the meaning is included.
- the parameter value is only a parameter value representing an existing QoS parameter
- the new parameter value is only Indicates the parameter value corresponding to the new QoS parameter
- the parameter value and the new parameter value are two independent objects, and there is no affiliation between them.

Based on the foregoing description of the embodiment shown in FIG. 1, a new method for calculating a QoS metric value is provided in this embodiment.

- the value corresponding to the service priority may be represented by a constant, and the value is different if the service is different.
- the real-time service is generally set to a high priority to ensure that the real-time service should have a higher scheduling priority.
- the value corresponding to the priority level can be set by each device manufacturer according to the result of the experiment. In the scheduling process of this embodiment, once the value is determined, the value is not adjusted to ensure the stability of the service scheduling.
- the QoS metric value when the QoS metric value is calculated, the value corresponding to the service priority is added, and the QoS scheduling value of the to-be-scheduled service is more guaranteed.
- both real-time services, voice services, and video call services assume that the values of the two service priorities are the same, but in the QoS parameters behind the respective services, the video call service must take into account the two QoS characteristics of delay and rate. Therefore, the calculated two service QoS metrics are different, and the order of the service adjustments is different.
- the scheduling method is that the first arriving service is scheduled first.
- the values corresponding to the respective priorities and the weights corresponding to the QoS parameters are the same, so that in the scheduling process, the pair cannot be The two services are better differentiated and scheduled.

- R i (t) (1- ⁇ )R i (t-1)+ ⁇ *r i (t)
- ⁇ is the weight of the updated average rate
- the device manufacturer can set the value by simulation, the value range [0, 1]. Therefore, based on the average rate threshold of the service, a metric of the data rate parameter of the service can be determined, and the average rate threshold can be obtained by the 3GPP protocol.

- target_jitter i is the delay jitter threshold of the service i.
- the jitter i can be monitored in real time, and the target_jitter i can be obtained through the 3GPP protocol.
- the base station configures a new QoS parameter for the new service or the new requirement, and assigns a corresponding weight to the new QoS parameter.
- the specific value of this weight can be determined by performing demand simulation on the new QoS parameters. Then, according to the newly obtained parameter value and weight, a calculation method is used to calculate a new QoS scheduling value according to the implementation flow shown in FIG. 1 and FIG. 2 described above.
- a method flow for how to perform service scheduling by combining parameter values of the new QoS parameter when a new QoS requirement occurs is provided, that is, the new parameter value is

- a QoS metric value of a service to be scheduled can be obtained, and the QoS metric value is applied to a scheduling process of a service to be scheduled, in order to be able to
- the performance evaluation may be performed by performing scenario simulation.
- the specific application scenario is described in Table 1 below.
- Table 1 it is determined by the two list items that at least the scenario needs to be The parameters involved, as well as the values of each parameter. These parameters include: cellular layout, system bandwidth, station spacing, base station transmit power, number of user equipment per cell, path loss model, wireless channel, transmission mode, service type, simulation time, 10 parameters, and in Table 1
- the corresponding numerical descriptions are given in the corresponding ones, and will not be repeated here. For details, refer to the description in Table 1 below. Combined with the description of Table 1, this example involves emulating a hybrid service model, namely video streaming service and video telephony service.
- the delay requirement is high, and a certain rate is also required, and for the video user (corresponding to the video stream service), the transmission rate has high requirements, so the QoS for the video telephony service is determined.
- Metric method The values are respectively [0.3, 0.7, 0], and for the high-definition video service QoS measurement method The values are [0.8, 0.2, 0] respectively.
- the symbols of the weights are listed, and the meanings of the specific representatives are the same as those of the similar symbols in the above formula.
- the prior art generally adopts an EPF (English full name: Enhanced Proportional Fair) algorithm to obtain a QoS scheduling value of a service.
- EPF Evolution full name: Enhanced Proportional Fair
- the EPF algorithm is widely used in existing products because it guarantees the characteristics of delay parameters and rate parameters in QoS characteristics.
- delay i and target_DL i are still expressed as the delay and delay threshold of the service data packet waiting for transmission.
- the delay threshold is small, and thus the priority variable c i is larger, more scheduling opportunities are obtained, and the QoS delay requirement can be satisfied.
- this method only considers the QoS characteristics of rate and delay, and is not easy to expand.
- the method fixes the weights of the QoS rate parameter and the delay parameter, and only adjusts the priority variable of the service scheduling. Therefore, the method cannot characterize new mobile Internet services and new QoS features, and fixes the weights of QoS parameters without obtaining better multiple QoS parameter optimization performance.
- Equation 8 ⁇ i (t) is the packet generation rate based on the traffic i delay, and ⁇ i (t) is the update weight of the delay and the average rate to track the traffic packet production.
- This scheduling algorithm must first simulate the business and model the mathematical expression, and then generate a QoS scheduling algorithm based on the expression for delay and rate characteristics.
- the method strongly relates the business mathematical model, considering the rate parameter and the delay parameter. It is difficult to extend to other QoS feature parameters.
- the weights of the rate and the delay are the same weights. Therefore, the weights cannot be adjusted to characterize the small characteristics of the service, and the service scheduling cannot be accurately implemented according to the QoS requirements.
- the second aspect is scheduling.
- the statistics on the delay in the process the second aspect is the statistics on the rate in the scheduling process. Specifically:
- the packet loss rate is about 2.2%.
- the packet loss rate is about 1.5%.
- the real-time service video telephony has a higher delay requirement, so the scheduling priority is higher, the corresponding delay is smaller, the scheduling priority of the video streaming service is lower, and the delay is larger.
- the delay of both services can meet the delay threshold.
- the maximum delay of the real-time service video phone is 88 ms, and the maximum delay of the video stream service is 240 ms.
- the delay and the data rate are effectively balanced.
- the simulation results show that compared with the maximum delay threshold, the scheduling delay is less than the delay threshold of 90ms for video telephony services, and the scheduling delay is less than the threshold of 220ms for video streaming services. It also satisfies the requirements of QoS delay.
- the delay of video telephony is slightly increased, while the delay of video streaming service is slightly reduced, the fluctuation of the instantaneous delay is smaller, and the performance is more balance.
- the QoS metric algorithm proposed by the embodiment of the present invention schedules users so that the data rate can guarantee the average rate of the service, and the average rate of the video telephone users is 65 kbps, which ensures the average rate of the service is 64 kbps, and the average rate of the video stream users is 2.1. Mbps guarantees an average rate of 2Mbps for the service.
- the PF algorithm good channel conditions and high instantaneous rate user scheduling are selected, while for the EPF algorithm, the delay service has a greater priority weight, so the data rate of the real-time service is basically unaffected, but for non-real time.
- Video stream service scheduling priority is low, so can not choose good channel condition scheduling, so performance is reduced, the average rate is 1.89Mbps, the loss is about 13.7%, can not meet the average rate requirements, and the edge rate is 1.676Mbps, loss It is about 6.9%.
- the QoS metric algorithm considers the QoS characteristics of the delay in addition to the rate parameter of the user, resulting in the incomplete best channel condition and the highest instantaneous rate being scheduled, comparing the PF algorithm, performance.
- the delay is the most important QoS parameter to choose a large weight (0.7)
- the rate is more important.
- the parameters have large weights, while the delay has smaller requirements, but still has some impact (weight 0.2), so the data rate has a slight loss, only 4%.
- the proposed method achieves a balance between QoS delay and rate to obtain more optimized performance.
- the simulation examples given in Table 1 above are given, and three implementation methods are given.
- the statistics include the video streaming service and the Video telephony service.
- the comparison objects include the average user rate and the user edge rate.
- the specific simulation method is the same as described in Table 1. The description is repeated, and the numerical values representing the statistical results are described above, and in Table 2, these statistical values or comparison values are only expressed in a more intuitive form.
- the QoS metric method proposed in this embodiment characterizes the QoS characteristics of the service by changing the weights of the respective QoS parameters, thereby being in the scheduling. Optimized system performance based on the multi-QoS characteristics of the service.

Description
本发明涉及无线通信技术领域,尤其涉及一种服务质量度量方法、装置及一种基站。The present invention relates to the field of wireless communication technologies, and in particular, to a service quality measurement method and apparatus, and a base station.
在当前的无线通信技术中,为了满足用户的业务体验,提出了业务的QoS(英文全称为:Quality of Service,中文全称为:服务质量)概念,用户需求可以通过QoS特性体现。目前基站通过业务的QoS特性为业务分配无线资源,从而提高用户的业务体验。而基站对业务的无线资源分配过程,也就是基站通过业务的QoS度量方法实现业务QoS调度的过程,而在该调度过程中,通过业务的QoS度量算法得到业务的QoS度量值非常重要。In the current wireless communication technology, in order to satisfy the user's service experience, the concept of QoS (English: Quality of Service, full name: quality of service) is proposed, and user requirements can be reflected by QoS characteristics. Currently, the base station allocates radio resources to services through the QoS feature of the service, thereby improving the user experience. The radio resource allocation process of the base station to the service is a process in which the base station implements the service QoS scheduling by using the QoS measurement method of the service, and in the scheduling process, it is very important to obtain the QoS metric value of the service through the QoS measurement algorithm of the service.
现有对业务的调度过程中,基于QoS特性中的速率参数和时延参数进行QoS度量,并最终实现业务资源的分配。比如采用增强型比例公平算法实现QoS度量。在具体实现过程中,这一方法适用于传统的业务类型,比如视频流业务、话音业务,其中,视频流业务对业务的速率要求较高,话音业务对业务的实时性要求较高,所以通过现有方法能够实现对上述两类业务的无线资源分配。但是,随着无线通信网络的发展,未来移动互联网衍生出了一些新型业务,如移动支付,微信等。这些新型业务在实现过程中有不同QoS需求,如移动支付业务,不仅需要保证业务的带宽即速率,同时也要求低的端到端时延和低的丢包率和误码率,此时,如果继续沿用上述QoS的度量方法,只能兼顾到QoS中的速率参数和时延参数特性,而对于这一新型业务的其它QoS特性需求将不能被满足,在后续的业务调度过程中,就会因为未及时准
确地分配到资源而导致业务失败。In the existing scheduling process for services, QoS metrics are performed based on rate parameters and delay parameters in the QoS characteristics, and finally, service resources are allocated. For example, an enhanced proportional fairness algorithm is used to implement QoS metrics. In a specific implementation process, the method is applicable to a traditional service type, such as a video stream service and a voice service. The video stream service requires a higher rate of the service, and the voice service requires a higher real-time service, so The existing method can realize wireless resource allocation to the above two types of services. However, with the development of wireless communication networks, the mobile Internet has spawned some new services, such as mobile payment and WeChat. These new services have different QoS requirements in the implementation process, such as mobile payment services, which not only need to guarantee the bandwidth of the service, ie, the rate, but also require low end-to-end delay and low packet loss rate and bit error rate. If the metric method of the above QoS is continued, only the rate parameter and the delay parameter characteristic in the QoS can be taken into consideration, and other QoS characteristic requirements for the new service cannot be satisfied, and in the subsequent service scheduling process, Because it is not timely
Really assigned to resources and cause business to fail.

本发明一实施例提供了一种服务质量度量方法,该方法通过基站执行,如图1所示,这一方法包括:An embodiment of the present invention provides a service quality measurement method, which is performed by a base station, as shown in FIG. 1, the method includes:
101、获取待调度业务的已有QoS参数的参数值和已有QoS参数对应的权值。101. Obtain a parameter value of an existing QoS parameter of the to-be-scheduled service and a weight corresponding to the existing QoS parameter.
在本实施例中,已有QoS参数包括:速率参数、时延参数、丢包率参数、时延抖动参数、误报率参数等,参数值为,通过3GPP(英文全称为:3rd Generation Partnership Project,中文全称为:第三代合作伙伴计划)协议或公开研究的新业务特性获取的各已有QoS参数对应的参数值,且每一个QoS参数对应一个权
值,该权值根据对各已有QoS参数的需求进行配置获得。In this embodiment, the existing QoS parameters include: a rate parameter, a delay parameter, a packet loss rate parameter, a delay jitter parameter, a false alarm rate parameter, etc., and the parameter value is passed through 3GPP (English full name: 3rd Generation Partnership Project) , Chinese full name: Third Generation Partnership Project) protocol or publicly researched new service characteristics to obtain the parameter values corresponding to each existing QoS parameter, and each QoS parameter corresponds to a right
A value obtained by configuring the requirements for each existing QoS parameter.
102、通过已有QoS参数的参数值和已有QoS参数对应的权值,计算得到待调度业务的QoS度量值。102. Calculate a QoS metric value of the service to be scheduled by using a parameter value of the existing QoS parameter and a weight corresponding to the existing QoS parameter.
在本发明实施例的具体实现过程中,通过对已有QoS参数的参数值和已有QoS参数对应的权值进行计算,得到QoS度量值。其中,计算形式包括:加权积计算,或者乘积计算等。In the specific implementation process of the embodiment of the present invention, the QoS metric value is obtained by calculating the parameter value of the existing QoS parameter and the weight value corresponding to the existing QoS parameter. Among them, the calculation form includes: weighted product calculation, or product calculation, and the like.
值得说明的是,在包括本实施例在内的本发明实施例中,为了描述简便,通过“参数值”描述“已有QoS参数的参数值”,通过“权值”描述“已有QoS参数对应的权值”,这两组对象代表的含义分别相同,只是为了更为简洁的描述,以简化形式出现。It should be noted that, in the embodiment of the present invention including the present embodiment, for the sake of simplicity of description, "parameter value" describes "parameter value of existing QoS parameter", and "weight" describes "existing QoS parameter". The corresponding weights, the two groups of objects represent the same meaning, but for a more concise description, appear in a simplified form.
当通过乘积形式计算时,比如,待调度业务包括两种已有QoS参数,其对应的参数值分别通过U1和U2表示,这两种QoS参数对应的权值分别通过w1和w2表示,则相应的该待调度业务的QoS度量值U=w1×U1+w2×U2。当然该举例中,待调度业务的QoS度量值还可以通过参数值和其对应的权值进行加权积计算得到,而这一加权积的计算方法可以通过下述公式(0)详述。When calculating by the product form, for example, the to-be-scheduled service includes two existing QoS parameters, and the corresponding parameter values are respectively represented by U1 and U2, and the weights corresponding to the two QoS parameters are respectively represented by w1 and w2, and corresponding The QoS metric value of the to-be-scheduled service is U=w1×U1+w2×U2. Of course, in this example, the QoS metric value of the service to be scheduled can also be calculated by weighted product of the parameter value and its corresponding weight, and the calculation method of the weighted product can be detailed by the following formula (0).
此外,值得说明的是,相比于现有技术,上述提到的参数值与权值的乘积后并作和的运算虽然可以对待调度业务进行区分,但是,相较于乘积运算,参数值和权值进行加权积计算时,收敛要快,并且对QoS度量值的变化敏感,能够以更细微差别进行业务区分,所以下述实施例将详细介绍参数值和权值进行加权积计算以得到QoS度量值的计算流程。In addition, it is worth noting that, compared with the prior art, the above-mentioned operation of summing the product of the parameter value and the weight may be distinguished from the service to be scheduled, but compared with the product operation, the parameter value and When the weight is calculated by weighted product, the convergence is fast, and it is sensitive to the change of the QoS metric value, and the service can be distinguished by more nuances. Therefore, the following embodiments will introduce the weighted product calculation of the parameter value and the weight in detail to obtain the QoS. The process of calculating the metrics.
在本实施例中,以参数值与权值进行加权积计算,得到QoS度量值为例进行说明。比如,待调度业务为业务i,该业务i的QoS参数包括:速率参数、时延参数、丢包率参数,其各自对应的参数值分别通过:表示,其中,作为下
标的dr表示数率、d1表示时延、p1r表示丢包率,t表示时间,且上述三种QoS参数对应的权值分别通过:表示,结合本实施例步骤102的描述,则业务i的QoS度量值Ui(t)可以通过下述公式(0)获得。In this embodiment, the weighted product is calculated by using the parameter value and the weight, and the QoS metric value is obtained as an example. For example, the service to be scheduled is the service i, and the QoS parameters of the service i include: a rate parameter, a delay parameter, and a packet loss rate parameter, and the corresponding parameter values respectively pass through: In the above, the dr as the subscript indicates the rate, d1 indicates the delay, p1r indicates the packet loss rate, and t indicates the time, and the weights corresponding to the above three QoS parameters are respectively passed: It is shown that, in combination with the description of step 102 of the embodiment, the QoS metric value U i (t) of the service i can be obtained by the following formula (0).
……公式(0)...form (0)
为了保证一个业务中的所有的QoS参数对应的权值指示一个业务,在本实施例中,一个业务的全部QoS参数对应的权值,和为1,比如在本实施例中即为:且在本发明提供的实施例中,QoS参数的需求度与QoS参数对应的权值正相关,即当待调度业务对任意一种QoS特性需求较高时,则该QoS特性参数对应的权值比其余QoS参数对应的权值大。比如,话音业务涉及的QoS参数包括:时延参数、速率参数,而话音业务对业务的实时性要求较高,则时延参数对应的权值要大于速率参数对应的权值,且其中的,需求度用于表征表征QoS参数在待调度业务中受重视的程度,需求度越高,QoS参数在待调度业务中越受重视。To ensure that all the QoS parameters in a service indicate a service, in this embodiment, the weights of all the QoS parameters of a service are 1 and, for example, in this embodiment: In the embodiment provided by the present invention, the required degree of the QoS parameter is positively correlated with the weight corresponding to the QoS parameter, that is, when the to-be-scheduled service has a high demand for any one of the QoS characteristics, the weight corresponding to the QoS characteristic parameter The weight corresponding to the remaining QoS parameters is larger. For example, the QoS parameters involved in the voice service include: a delay parameter and a rate parameter, and the voice service has a higher real-time requirement for the service, and the weight corresponding to the delay parameter is greater than the weight corresponding to the rate parameter, and wherein, The demand degree is used to characterize the extent to which the QoS parameters are valued in the service to be scheduled. The higher the demand degree, the more attention is paid to the QoS parameters in the service to be scheduled.
值得说明的是,在本实施例中,每种待调度业务设置有至少一种QoS参数,并且待调度业务不同,待调度业务对应的权值中至少有一个不同,比如有两种待调度业务A、B,其中,业务A涉及3个权值,分别为:A1、A2、A3;业务B同样涉及三个权值分别为:B1、B2、B3,则其中这两组数中,每组中至少有一个数的数值与另一组中的数值不同。这样就能够通过权值的差别来进行业务区分。It is to be noted that, in this embodiment, each to-be-scheduled service is configured with at least one QoS parameter, and the to-be-scheduled service is different, and at least one of the weights to be scheduled is different, for example, there are two to-be-scheduled services. A, B, where service A involves 3 weights, respectively: A1, A2, A3; Service B also involves three weights: B1, B2, B3, then each of the two groups The value of at least one of the numbers is different from the value in the other group. This makes it possible to differentiate the business by the difference in weights.
在具体应用过程中,业务的QoS特性包括数据速率,时延,误包率,丢包率,时延抖动等,这些特性可以分别通过速率参数、
时延参数、误包率参数、丢包率参数、时延抖动参数等表示,通过对这些参数的描述来区分不同业务特性。如实时业务中的话音业务,则要求传输时延低,这就需要调度该业务时优先级高以减小调度时延;而又如非实时业务中的视频流业务,则对时延要求低,而对速率要求高,则调度该业务时分配更多的带宽,以保证数据速率。因此,上述的各项QoS参数的比重不同就表示不同的业务,也就是说,可以用这些参数的权值来进行业务区分。比如,话音业务中时延要求高,故可以加大权值,确保该业务的优先调度权。而这些权值的确定是基于业务的特性来确定,也可以根据仿真业务的来确定。一旦业务确定,其权值就确定,不会随时间变化而变化。In a specific application process, the QoS characteristics of the service include data rate, delay, packet error rate, packet loss rate, delay jitter, etc., and these characteristics can respectively pass the rate parameter,
The delay parameter, the error packet rate parameter, the packet loss rate parameter, the delay jitter parameter, and the like are represented, and different service characteristics are distinguished by describing the parameters. For example, the voice service in the real-time service requires a low transmission delay, which requires a high priority to reduce the scheduling delay when scheduling the service, and a low delay requirement for the video stream service in the non-real-time service. And the rate requirement is high, then allocate more bandwidth when scheduling the service to ensure the data rate. Therefore, the different proportions of the above various QoS parameters indicate different services, that is, the weights of these parameters can be used for service differentiation. For example, in the voice service, the delay requirement is high, so the weight can be increased to ensure the priority scheduling right of the service. The determination of these weights is based on the characteristics of the service, and can also be determined based on the simulation service. Once the business is determined, its weight is determined and does not change over time.
值得说明的是,在本发明实施例中,在计算待调度业务的QoS度量值时,这一待调度业务包括的QoS参数可以有一种或者几种,相应的,有与QoS参数个数等同的权值个数。结合上述描述,这些参数值和权值进行乘积或者进行加权积计算得到待调度业务的QoS度量值。It should be noted that, in the embodiment of the present invention, when calculating the QoS metric value of the service to be scheduled, the QoS parameter included in the to-be-scheduled service may have one or several types, and correspondingly, the number of QoS parameters is equal. The number of weights. Combined with the above description, these parameter values and weights are multiplied or weighted product is calculated to obtain a QoS metric value of the service to be scheduled.
本发明实施例提供了一种服务质量度量方法,在获取到当前待调度业务的已有QoS参数的参数值和已有QoS参数对应的权值之后,通过这些参数值和权值来计算待调度业务的QoS度量值,由于不同业务的权值不同,能够通过权值进行业务区分,从而能够计算出业务更为准确的QoS度量值。而现有技术的QoS度量方法中,很大程度上得到的业务的QoS度量值相同,从而在业务调度过程中难以进行业务区分,从而导致业务实现失败。但是本发明实施例提供的技术方案,能够计算出业务更为准确的QoS调度值,从而准确地实现业务调度,提高业务实现的成功率。The embodiment of the present invention provides a QoS measurement method. After obtaining the parameter value of the existing QoS parameter of the current to-be-scheduled service and the weight corresponding to the existing QoS parameter, the parameter value and the weight are used to calculate the to-be-scheduled. The QoS metric of the service can be differentiated by the weights because the weights of different services are different, so that more accurate QoS metrics can be calculated. In the QoS measurement method of the prior art, the QoS metrics of the services are obtained in the same manner, so that it is difficult to perform service differentiation in the service scheduling process, and the service implementation fails. However, the technical solution provided by the embodiment of the present invention can calculate a more accurate QoS scheduling value of the service, thereby accurately implementing service scheduling and improving the success rate of service implementation.
值得说明的是,在本发明下述实施例中,“已有QoS参数”
通过“QoS参数”表示,当然在待调度业务存在新的QoS需求时,会相应出现新的QoS参数、新的QoS参数对应的参数值、新的QoS参数对应的权值,而为了简便描述,在本实施例中,上述三个对象分别通过:新的QoS参数、新的参数值、新的权值描述。结合上述步骤102中的描述,只是为不同的对象进行了适应的简化描述,如果有重合的部分,不代表包含意思,比如,参数值只是代表已有QoS参数的参数值,新的参数值只是表示新的QoS参数对应的参数值,而参数值和新的参数值是两个独立的对象,之间不存在从属关系。It should be noted that in the following embodiments of the present invention, "the existing QoS parameters"
The "QoS parameter" indicates that, of course, when there is a new QoS requirement for the to-be-scheduled service, new QoS parameters, parameter values corresponding to the new QoS parameters, and weights corresponding to the new QoS parameters appear correspondingly, and for the sake of simplicity, In this embodiment, the above three objects respectively pass: a new QoS parameter, a new parameter value, and a new weight description. In combination with the description in the above step 102, only a simplified description of the adaptation of different objects is performed. If there is a coincident part, it does not mean that the meaning is included. For example, the parameter value is only a parameter value representing an existing QoS parameter, and the new parameter value is only Indicates the parameter value corresponding to the new QoS parameter, and the parameter value and the new parameter value are two independent objects, and there is no affiliation between them.
本发明另一实施例提供了一种服务质量度量方法,基于上述如图1所示实施例的描述,在本实施例中提供了一种新的计算QoS度量值的方法,在这一计算方法中,在获取参数值和权值时,同时考虑了待调度业务的优先级,如图2所示,这一方法包括:Another embodiment of the present invention provides a service quality measurement method. Based on the foregoing description of the embodiment shown in FIG. 1, a new method for calculating a QoS metric value is provided in this embodiment. In the process of obtaining the parameter value and the weight, the priority of the service to be scheduled is considered, as shown in FIG. 2, the method includes:
201、获取待调度业务对应的业务优先级。201. Obtain a service priority corresponding to the service to be scheduled.
202、通过业务优先级对应的数值、参数值和权值,计算得到QoS度量值。202. Calculate the QoS metric value by using a value corresponding to the service priority, a parameter value, and a weight.
值得说明的是,在本实施例中步骤202与上述的步骤102相对应,只是本实施例中得到的QoS度量值,由上述步骤102中得到的QoS度量值与业务优先级对应的数值作乘积得到。It should be noted that, in the embodiment, the step 202 corresponds to the step 102 described above, except that the QoS metric value obtained in the embodiment is multiplied by the QoS metric value obtained in the above step 102 and the value corresponding to the service priority. get.
具体的结合上述步骤102中给出的公式(0)的描述,综合业务优先级之后,QoS度量值的计算方法,可通过下述公式(0-1)得到。Specifically, in combination with the description of the formula (0) given in the above step 102, after the integrated service priority, the calculation method of the QoS metric value can be obtained by the following formula (0-1).
……公式(0-1)...form (0-1)
在该公式(0-1)中,λi为业务i的优先级对应的数值,该公式中的其余参数,与上述公式(0)中的相关描述相同,在此
不再重复说明。In the formula (0-1), λ i is a value corresponding to the priority of the service i, and the remaining parameters in the formula are the same as those in the above formula (0), and the description thereof will not be repeated here.
结合上述描述,本发明实施例中,业务优先级主要用于区分大类的业务,如实时业务和非实时业务,业务优先级对应的数值可以通过一个常量表示,业务不同,这个值就不同。一般设定实时业务为高优先级,以确保实时业务应该有更高的调度优先级。该优先级对应的数值是可以由各设备厂商根据自己的实验结果来设置,且在本实施例调度过程中,该值一旦确定便不再调整,以保证业务调度的稳定性。With reference to the foregoing description, in the embodiment of the present invention, the service priority is mainly used to distinguish a large class of services, such as a real-time service and a non-real-time service. The value corresponding to the service priority may be represented by a constant, and the value is different if the service is different. The real-time service is generally set to a high priority to ensure that the real-time service should have a higher scheduling priority. The value corresponding to the priority level can be set by each device manufacturer according to the result of the experiment. In the scheduling process of this embodiment, once the value is determined, the value is not adjusted to ensure the stability of the service scheduling.
此外值得说明的是,在本实施例中,在计算QoS度量值时添加业务优先级对应的数值,更能保证待调度业务的QoS调度值不同。比如,都是实时业务,话音业务和视频通话业务,假设这两种业务优先级对应的数值相同,但各自业务后面的QoS参数中,视频通话业务要兼顾时延和速率两个QoS特性参数,所以计算出来的两个业务QoS度量值不同,进而业务调的度次序也就不同。当然,即使最后计算得到的QoS度量值结果相同,那么调度方法就是先到达的业务先调度。而在现有技术中,对于同是实时业务的话音业务和视频通话业务来说,其各自对应的优先级对应的数值和QoS参数对应的权值均相同,这样在调度过程中,就不能对该两种业务较好地进行区分调度。It should be noted that, in this embodiment, when the QoS metric value is calculated, the value corresponding to the service priority is added, and the QoS scheduling value of the to-be-scheduled service is more guaranteed. For example, both real-time services, voice services, and video call services assume that the values of the two service priorities are the same, but in the QoS parameters behind the respective services, the video call service must take into account the two QoS characteristics of delay and rate. Therefore, the calculated two service QoS metrics are different, and the order of the service adjustments is different. Of course, even if the last calculated QoS metric result is the same, the scheduling method is that the first arriving service is scheduled first. In the prior art, for the voice service and the video call service that are both real-time services, the values corresponding to the respective priorities and the weights corresponding to the QoS parameters are the same, so that in the scheduling process, the pair cannot be The two services are better differentiated and scheduled.
本发明另一实施例提供了一种服务质量度量方法,结合上述如图1或如2所示的实施例中,在计算QoS度量值时涉及到参数值,QoS参数至少包括:速率参数、时延参数、丢包率参数、时延抖动参数、误报率参数等,在这一实施例中将详细介绍前四个参数值的获取方法,具体包括:Another embodiment of the present invention provides a QoS measurement method. In combination with the foregoing embodiment shown in FIG. 1 or FIG. 2, when calculating a QoS metric value, a parameter value is involved, and the QoS parameter includes at least: a rate parameter, a time The delay parameter, the packet loss rate parameter, the delay jitter parameter, the false alarm rate parameter, etc., in this embodiment, the method for obtaining the first four parameter values will be described in detail, and specifically includes:
a、当QoS参数包括丢包率参数时,获取待调度业务的平均丢包率和待调度业务的丢包率门限,并根据该平均丢包率和丢包
率门限计算,得到丢包率参数对应的参数值。a. When the QoS parameter includes the packet loss rate parameter, the average packet loss rate of the service to be scheduled and the packet loss rate threshold of the to-be-scheduled service are obtained, and the average packet loss rate and packet loss are obtained according to the average packet loss rate.
The rate threshold is calculated, and the parameter value corresponding to the packet loss rate parameter is obtained.
在具体实现过程中,可以通过下述公式(1)计算丢包率参数对应的参数值:In the specific implementation process, the parameter value corresponding to the packet loss rate parameter can be calculated by the following formula (1):
......公式(1) ......Formula 1)
在该公式(1)中,i表示业务类型,t表示时间,表示业务i的丢包率参数值,avr_PLRi是平均丢包率,target_PLRi是业务i的丢包率门限。其中,平均丢包率是在调度过程中不断统计业务i传输情况获得的,而丢包率门限为3GPP协议中对该值的定义值,在此不再重复说明。In the formula (1), i represents the type of service, and t represents time. Indicates the packet loss rate parameter value of service i, avr_PLR i is the average packet loss rate, and target_PLR i is the packet loss rate threshold of service i. The average packet loss rate is obtained by continuously counting the traffic of the service i during the scheduling process, and the packet loss rate threshold is a defined value of the value in the 3GPP protocol, and is not repeated here.
b、当QoS参数包括时延参数时,获取待调度业务等待传输的时延和待调度业务的时延门限,并根据该时延和时延门限计算,得到时延参数对应的参数值。When the QoS parameter includes the delay parameter, the delay of the to-be-scheduled service and the delay threshold of the to-be-scheduled service are obtained, and the parameter value corresponding to the delay parameter is obtained according to the delay and the delay threshold.
在具体实现过程中,可以通过下述公式(2)计算丢包率参数对应的参数值:In the specific implementation process, the parameter value corresponding to the packet loss rate parameter can be calculated by the following formula (2):
......公式(2)...formula (2)
在该公式(2)中,i表示待调度业务,t表示时间,表示时延参数值,delayi是业务数据包等待传输的时延,target_DLi是业务的时延门限。其中,delayi可以通过对业务i的数据包实施检测得到,target_DLi的取值与3GPP中定义的该类业务的该取值相同。In the formula (2), i represents the service to be scheduled, and t represents the time. Indicates the delay parameter value, delay i is the delay of the service data packet waiting for transmission, and target_DL i is the delay threshold of the service. The delay i can be obtained by detecting the data packet of the service i, and the value of the target_DL i is the same as the value of the service defined in the 3GPP.
c、当QoS参数包括速率参数时,获取待调度业务数据包的瞬时传输速率、待调度业务的平均速率门限和待调度业务的实际传输平均速率,并根据瞬时传输平均速率、平均数率门限和实际
传输平均速率计算,得到速率参数对应的参数值。c. When the QoS parameter includes the rate parameter, obtain the instantaneous transmission rate of the service data packet to be scheduled, the average rate threshold of the service to be scheduled, and the actual transmission average rate of the service to be scheduled, and according to the instantaneous transmission average rate, the average rate threshold, and Actual
The average transmission rate is calculated, and the parameter value corresponding to the rate parameter is obtained.
......公式(3)...formula (3)
在该公式(3)中,i表示待调度业务,t表示时间,表示业务i的速率参数值,ri(t)是业务i数据包传输的瞬时传输速率,是业务i的平均速率门限,Ri(t)是业务i数据包实际传输平均速率。且在本实施例中,Ri(t)与ri(t)存在如下关系,表示为公式(4)。In the formula (3), i represents the service to be scheduled, and t represents the time. Representing the rate parameter value of service i, r i (t) is the instantaneous transmission rate of the service i packet transmission, Is the average rate threshold of service i, and R i (t) is the average transmission rate of the service i packet. In the present embodiment, R i (t) and r i (t) have the following relationship and are expressed as formula (4).
Ri(t)=(1-τ)Ri(t-1)+τ*ri(t)R i (t)=(1-τ)R i (t-1)+τ*r i (t)
......公式(4)...formula (4)
其中,τ是更新平均速率的权值,设备制造商可以通过仿真来设定该值,取值范围[0,1]。因此,基于业务的平均速率门限,就能确定该业务的数据速率参数的度量方法,而这一平均速率门限可以通过3GPP协议得到。Where τ is the weight of the updated average rate, the device manufacturer can set the value by simulation, the value range [0, 1]. Therefore, based on the average rate threshold of the service, a metric of the data rate parameter of the service can be determined, and the average rate threshold can be obtained by the 3GPP protocol.
d、在具体的实现过程中,QoS参数还包括时延抖动参数,而在具体实现过程中,时延抖动参数对应的参数值可以通过下述公式(5)计算得到。d. In the specific implementation process, the QoS parameter further includes a delay jitter parameter, and in the specific implementation process, the parameter value corresponding to the delay jitter parameter can be calculated by the following formula (5).
......公式(5)...formula (5)
在该公式(5)中,i表示待调度业务类型,t表示时间,表示时延抖动参数值,jitteri是业务i数据包传输的时延抖动值,target_jitteri是业务i的时延抖动门限。且其中的jitteri可以实时监
测得到,target_jitteri可以通过3GPP协议得到。In the formula (5), i represents the type of service to be scheduled, and t represents time. Indicates the delay jitter parameter value, jitter i is the delay jitter value of the service i packet transmission, and target_jitter i is the delay jitter threshold of the service i. And the jitter i can be monitored in real time, and the target_jitter i can be obtained through the 3GPP protocol.
值得说明的是,上述五个公式,只是列举了四种参数值的一种计算方法,且上述提出的参数值的计算方法较为简单,能够节约计算资源,但是为了实现更好的调度性能,上述参数值可以通过其余方法计算方法得到,现有技术中,任何可以获得数据速率参数,时延参数,和丢包率参数等参数值的计算方法均在本发明的保护范围之列。It is worth noting that the above five formulas only enumerate a calculation method of four parameter values, and the calculation method of the parameter values proposed above is relatively simple, which can save computational resources, but in order to achieve better scheduling performance, the above The parameter value can be obtained by the remaining method calculation methods. In the prior art, any calculation method for obtaining parameter values such as a data rate parameter, a delay parameter, and a packet loss rate parameter is included in the protection scope of the present invention.
此外,随着网络技术的发展,会不断产生新的业务,或者对已有业务产生新的QoS需求。当产生新业务时或者业务的新需求时,基站会为该新业务或者新需求配置新的QoS参数,并为新的QoS参数分配相应的权值。这一权值的具体取值,获取可以通过对新的QoS参数进行需求仿真来确定。进而根据该新得到的参数值和权值,结合或者根据上述如图1和图2所示的实现流程给出计算方法计算新的QoS调度值。In addition, with the development of network technology, new services will continue to be generated, or new QoS requirements will be generated for existing services. When a new service or a new requirement of the service is generated, the base station configures a new QoS parameter for the new service or the new requirement, and assigns a corresponding weight to the new QoS parameter. The specific value of this weight can be determined by performing demand simulation on the new QoS parameters. Then, according to the newly obtained parameter value and weight, a calculation method is used to calculate a new QoS scheduling value according to the implementation flow shown in FIG. 1 and FIG. 2 described above.
结合上述四种获取QoS参数对应的参数值的计算方法,在出现新的QoS需求时,同样可以根据上述类似方法得到一个针对给新的QoS需求对应的新的参数值的计算公式。In combination with the above four methods for calculating the parameter values corresponding to the QoS parameters, when a new QoS requirement occurs, a calculation formula for the new parameter value corresponding to the new QoS requirement can also be obtained according to the similar method described above.
值得说明的是,如果要描述具有相同QoS参数的新业务,则可调整权值的取值,进而通过不同的QoS参数权值来表征该业务。It is worth noting that if a new service with the same QoS parameter is to be described, the value of the weight can be adjusted, and then the service is characterized by different QoS parameter weights.
此外值得说明的是,在本实施例中,提供了在出现新的QoS需求时,如何结合这一新的QoS参数的参数值进行业务调度的方法流程,也就是将该新的参数值与该新的的权值进行计算,并将计算后得到的值,直接与该待调度业务已存在的参数值和权值的计算结果继续进行乘积运算,当然的这一新的参数值与该新的权值的计算方法与前述步骤102中描述的方法相同,在此不再赘述。而现有技术在业务调度过程中,计算业务的QoS度量值时,一般采用增强比例公平算法,只考虑了速率参数和时延参数,并且这两种参数中的一种参数是在另一个
参数的基础上得到的,比如,一种参数值是通过另一种参数值的对数或者指数形式计算得到,所以当出现了新的QoS参数需求,如果继续使用上述算法,将无法得到包括新的QoS需求的业务QoS度量值。而结合上述描述,本发明实施例提供的QoS度量方法易于扩展QoS参数。In addition, it should be noted that, in this embodiment, a method flow for how to perform service scheduling by combining parameter values of the new QoS parameter when a new QoS requirement occurs is provided, that is, the new parameter value is The new weight is calculated, and the calculated value is directly multiplied with the calculation result of the existing parameter values and weights of the to-be-scheduled service, of course, the new parameter value and the new one. The calculation method of the weight is the same as the method described in the foregoing step 102, and details are not described herein again. In the prior art, in the service scheduling process, when calculating the QoS metric value of the service, the enhanced proportional fair algorithm is generally adopted, only the rate parameter and the delay parameter are considered, and one of the two parameters is in another
Based on the parameters, for example, one parameter value is calculated by the logarithm or exponential form of another parameter value, so when new QoS parameter requirements appear, if you continue to use the above algorithm, you will not be able to get new Service QoS metrics for QoS requirements. With the above description, the QoS metric method provided by the embodiment of the present invention is easy to extend QoS parameters.
在本发明的另一实施例中提供了一种服务质量度量方法,该方法具体阐述了,在得到QoS度量值之后,如何根据这一度量值进行业务调度的方法,这一调度方法具体包括下述两个方面。In another embodiment of the present invention, a method for measuring a quality of service is provided. The method specifically describes, after obtaining a QoS metric value, how to perform service scheduling according to the metric value, and the scheduling method specifically includes Two aspects are mentioned.
第一方面,当存在多个待调度业务时,通过上述公式(0)或者公式(0-1)得到每个所述待调度业务对应的QoS度量值,对QoS度量值进行比较,得到最大QoS度量值,则优先调度该最大QoS度量值对应的待调度业务。In the first aspect, when there are multiple to-be-scheduled services, the QoS metric corresponding to each to-be-scheduled service is obtained by using the above formula (0) or formula (0-1), and the QoS metric values are compared to obtain the maximum QoS. The metric value is used to preferentially schedule the to-be-scheduled service corresponding to the maximum QoS metric value.
第二方面,当存在多个待调度任务时,可以将上述获取到的QoS度量值作为加权因子加权调度算法来得到更优的QoS调度算法,以获取系统性能和业务QoS体验的折中,优先调度QoS度量值调度算法加权后的最大数值,并优先调度该最大数值对应的待调度业务。比如,用户调度算法为ci(t),QoS度量值为Ui(t),获取的最大数值为:maxiUi(t)*ci(t)。In a second aspect, when there are multiple tasks to be scheduled, the obtained QoS metric value can be used as a weighting factor weighted scheduling algorithm to obtain a better QoS scheduling algorithm, so as to obtain a compromise between system performance and service QoS experience. The maximum value weighted by the QoS metric scheduling algorithm is scheduled, and the to-be-scheduled service corresponding to the maximum value is preferentially scheduled. For example, the user scheduling algorithm is c i (t), the QoS metric value is U i (t), and the maximum value obtained is: max i U i (t)*c i (t).
其中,调度算法值表示待调度业务通过调度算法得到的数值,调度值用于表示待调度业务被调度的顺序。The scheduling algorithm value represents a value obtained by the scheduling algorithm by the scheduling algorithm, and the scheduling value is used to indicate the order in which the to-be-scheduled services are scheduled.
值得说明的是,在上述第二方面中提到的,对调度算法作加权,实际是指对通过该调度算法得到的具体数值作加权,则在本实施例中,ci(t)称为调度算法值。如在上述第二方面中,ci(t)可以是一些的高性能调度算法,如基于博弈论的调度算法,基于总的分配资源和用户实时的环境条件进行调度以达到系统最优的性能。因此在该调度算法中根据资源和用户信道条件参数确定了用户调度的ci(t)值,再通过Ui(t)加权,就获得满足业务QoS特性
的高性能调度算法。It should be noted that, in the second aspect mentioned above, the weighting of the scheduling algorithm actually refers to weighting the specific values obtained by the scheduling algorithm, and in this embodiment, c i (t) is called Scheduling algorithm values. As in the second aspect above, c i (t) may be some high performance scheduling algorithms, such as a game theory based scheduling algorithm, based on total allocated resources and real-time environmental conditions of the user to achieve optimal system performance. . Therefore, in the scheduling algorithm, the c i (t) value of the user scheduling is determined according to the resource and user channel condition parameters, and then U i (t) weighting is performed to obtain a high performance scheduling algorithm that satisfies the service QoS characteristics.
本发明另一实施例提供了一种服务质量度量方法,通过这一方法能够获取到待调度业务的QoS度量值,并将这一QoS度量值应用到对待调度业务的调度过程中,为了能够更为直观的介绍本发明给出的技术方案,本实施例以具体实例的形式进行说明,且结合了针对该实例的现有业务调度形式来对比说明本发明实施例的技术效果。Another embodiment of the present invention provides a service quality measurement method, by which a QoS metric value of a service to be scheduled can be obtained, and the QoS metric value is applied to a scheduling process of a service to be scheduled, in order to be able to In order to introduce the technical solution of the present invention in an intuitive manner, the present embodiment is described in the form of a specific example, and the technical effect of the embodiment of the present invention is compared with the existing service scheduling form for the example.
在本实施例的具体实现过程中,可以通过对场景仿真来进行性能评估,这一具体应用场景描述如下表1所示,在该表1中,通过两列表项确定了这一场景中至少需要涉及的参数,以及各参数的取值。这些参数包括:蜂窝布局、系统带宽、站间距、基站发射功率、每个小区下的用户设备数、路径耗损模型、无线信道、传输模式、业务类型、仿真时间10项参数,且在该表1中给出了其对应的数值描述,在此不再一一重复,具体内容可参见下述表1中的描述。结合该表1的描述,本实例中涉及仿真混合业务模型,即视频流业务和视频电话业务。由于视频电话用户传输实时业务,故对时延要求较高,同时也要求一定的速率,而对于视频用户(对应视频流业务),对传输速率有较高的要求,所以确定对于视频电话业务QoS度量方法中分别取值为[0.3,0.7,0],而对于高清视频业务QoS度量方法中
分别取值为[0.8,0.2,0]。在本实例中,列举的是各权值的表示符号,其具体代表的意义,与上述公式中同类标示符号所表示的意义相同。In the specific implementation process of the embodiment, the performance evaluation may be performed by performing scenario simulation. The specific application scenario is described in Table 1 below. In the table 1, it is determined by the two list items that at least the scenario needs to be The parameters involved, as well as the values of each parameter. These parameters include: cellular layout, system bandwidth, station spacing, base station transmit power, number of user equipment per cell, path loss model, wireless channel, transmission mode, service type, simulation time, 10 parameters, and in Table 1 The corresponding numerical descriptions are given in the corresponding ones, and will not be repeated here. For details, refer to the description in Table 1 below. Combined with the description of Table 1, this example involves emulating a hybrid service model, namely video streaming service and video telephony service. Since the video telephony user transmits the real-time service, the delay requirement is high, and a certain rate is also required, and for the video user (corresponding to the video stream service), the transmission rate has high requirements, so the QoS for the video telephony service is determined. Metric method The values are respectively [0.3, 0.7, 0], and for the high-definition video service QoS measurement method The values are [0.8, 0.2, 0] respectively. In the present example, the symbols of the weights are listed, and the meanings of the specific representatives are the same as those of the similar symbols in the above formula.
表1Table 1
基于上述应用场景,现有技术一般采用EPF(英文全称为:Enhanced Proportional Fair,中文全称为:增强型比例公平)算法来获取业务的QoS调度值。EPF算法由于保证了QoS特性中时延参数和速率参数的特征而在现有产品中得到广泛的应用。Based on the above application scenarios, the prior art generally adopts an EPF (English full name: Enhanced Proportional Fair) algorithm to obtain a QoS scheduling value of a service. The EPF algorithm is widely used in existing products because it guarantees the characteristics of delay parameters and rate parameters in QoS characteristics.
目前采用的,EPF基本算法为:Currently used, the basic EPF algorithm is:
......公式(6)...Formula (6)
在该公式(6)中,表示比例公平(英文全称为:Proportional Fair,英文简称为:PF)调度算法,这里ri(t)是业务i数据包传输的瞬时速率,Ri(t)是业务i数据包实际统计出的传输平均速率,且这两者之间的关系如上述公式(4)所示。ci是业务优先级变量,通过下述公式(7)表示。In the formula (6), The proportional fair (English full name: Proportional Fair, English abbreviation: PF) scheduling algorithm, where r i (t) is the instantaneous rate of packet transmission of service i, and R i (t) is the actual statistics of the packet of service i. The average rate of transmission is transmitted, and the relationship between the two is as shown in the above formula (4). c i is a business priority variable and is expressed by the following formula (7).
......公式(7)...Formula (7)
在该公式(7)中,delayi和target_DLi仍然表示为业务数据包
等待传输的时延和时延门限。In the formula (7), delay i and target_DL i are still expressed as the delay and delay threshold of the service data packet waiting for transmission.
结合对上述公式(7)的描述,对于实时业务,时延门限小,因而优先级变量ci更大,获得更多的调度机会,QoS时延要求也就能得到满足。但是该方法只考虑了速率和时延的QoS特性,不易于扩展。同时该方法固定了QoS速率参数和时延参数的权值,只调整业务调度的优先级变量。因此该方法不能表征移动互联网新业务和新QoS特征,且固定了QoS参数的权值而不能获得更好的多个QoS参数优化性能。Combined with the description of the above formula (7), for the real-time service, the delay threshold is small, and thus the priority variable c i is larger, more scheduling opportunities are obtained, and the QoS delay requirement can be satisfied. However, this method only considers the QoS characteristics of rate and delay, and is not easy to expand. At the same time, the method fixes the weights of the QoS rate parameter and the delay parameter, and only adjusts the priority variable of the service scheduling. Therefore, the method cannot characterize new mobile Internet services and new QoS features, and fixes the weights of QoS parameters without obtaining better multiple QoS parameter optimization performance.
现有技术中,对于考虑了平均速率和时延门限的EPF调度算法,其表达式为:In the prior art, for an EPF scheduling algorithm that considers an average rate and a delay threshold, the expression is:
......公式(8)...Formula (8)
在该公式8中,αi(t)是基于业务i时延的包生成速率,βi(t)是时延和平均速率的更新权值,以跟踪业务数据包生产。In Equation 8, α i (t) is the packet generation rate based on the traffic i delay, and β i (t) is the update weight of the delay and the average rate to track the traffic packet production.
这种调度算法必须先模拟业务而建模数学表达式,然后基于该表达式生成时延和速率特征的QoS调度算法,但该方法强相关业务数学模型,考虑了速率参数和时延参数,很难扩展到其他的QoS特性参数。同时,速率和时延的权值采用相同的权值,故不能通过调整权值来表征业务的微小特性,不能按照QoS需求准确实现业务调度。This scheduling algorithm must first simulate the business and model the mathematical expression, and then generate a QoS scheduling algorithm based on the expression for delay and rate characteristics. However, the method strongly relates the business mathematical model, considering the rate parameter and the delay parameter. It is difficult to extend to other QoS feature parameters. At the same time, the weights of the rate and the delay are the same weights. Therefore, the weights cannot be adjusted to characterize the small characteristics of the service, and the service scheduling cannot be accurately implemented according to the QoS requirements.
在介绍完上述三种度量算法之后,现结合上述表1所示的具体实例,通过这三种方法进行仿真,得到的仿真结果具体为,且分为两个方面进行介绍,第二方面为调度过程中时延方面的统计,第二方面为调度过程中速率方面的统计。具体为:After introducing the above three measurement algorithms, the simulation results obtained by the three methods are combined with the specific examples shown in Table 1 above, and the obtained simulation results are specifically described in two aspects. The second aspect is scheduling. The statistics on the delay in the process, the second aspect is the statistics on the rate in the scheduling process. Specifically:
第一、时延方面:First, the delay:
PF算法中,调度信道条件好和瞬时速率高的用户以保证用户的吞吐量,而忽略了业务的其他QoS特性,如时延特性,所以使用户调
度时延大于业务的最大时延门限而造成数据丢包,尤其是对于实时业务,如视频电话,可以看出丢包率约为2.2%。对于非实时的视频流业务也造成一定的丢包,大约在1.5%。In the PF algorithm, users with good channel conditions and high instantaneous rate are guaranteed to ensure the throughput of the user, while ignoring other QoS characteristics of the service, such as delay characteristics, so that the user adjusts
The data delay is greater than the maximum delay threshold of the service, which causes data loss. Especially for real-time services, such as video telephony, the packet loss rate is about 2.2%. For non-real-time video streaming services, it also caused a certain amount of packet loss, about 1.5%.
EPF算法中,由于实时业务视频电话有更高的时延要求,因此调度的优先级更高,相应的时延较小,视频流业务的调度优先级较低,时延较大。但由于增加了时延因子,故两种业务的时延都能满足时延门限的要求,实时业务视频电话的最大时延是88ms,视频流业务的最大时延是240ms。In the EPF algorithm, the real-time service video telephony has a higher delay requirement, so the scheduling priority is higher, the corresponding delay is smaller, the scheduling priority of the video streaming service is lower, and the delay is larger. However, due to the increase of the delay factor, the delay of both services can meet the delay threshold. The maximum delay of the real-time service video phone is 88 ms, and the maximum delay of the video stream service is 240 ms.
采用本发明提出的多QoS度量算法,由于采用不同的权值来度量两个QoS参数,故有效地平衡时延和数据速率。仿真结果看出,比较PF调度,由于受到最大时延门限的约束,对于视频电话业务,调度时延小于时延门限90ms的要求,而对于视频流业务,调度时延也小于门限220ms的要求,同样满足QoS时延的要求。但由于在加权因子中也考虑了时延和速率的影响,比较改进的PF算法,视频电话的时延稍微增加,而视频流业务的时延稍微减小,即时延的波动更小,性能更加平衡。With the multi-QoS metric algorithm proposed by the present invention, since different QoS parameters are measured by using different weights, the delay and the data rate are effectively balanced. The simulation results show that compared with the maximum delay threshold, the scheduling delay is less than the delay threshold of 90ms for video telephony services, and the scheduling delay is less than the threshold of 220ms for video streaming services. It also satisfies the requirements of QoS delay. However, due to the influence of delay and rate in the weighting factor, compared with the improved PF algorithm, the delay of video telephony is slightly increased, while the delay of video streaming service is slightly reduced, the fluctuation of the instantaneous delay is smaller, and the performance is more balance.
第二、速率方面:Second, the rate aspect:
通过本发明实施例提出的QoS度量算法来调度用户,使其数据速率能够保证业务的平均速率,视频电话用户平均速率65kbps,保证了业务的平均速率64kbps需求,而视频流用户的平均速率为2.1Mbps,保证了业务的平均速率2Mbps需求。在PF算法中,选择好的信道条件和高瞬时速率的用户调度,而对于EPF算法,时延业务有更大的优先级权值,故实时业务的数据速率基本不受影响,但对于非实时视频流业务,调度的优先级低,因此不能选择好的信道条件调度,故性能降低,平均速率为1.89Mbps,损失约为13.7%,不能满足平均速率的要求,而边缘速率为1.676Mbps,损失约为6.9%。
The QoS metric algorithm proposed by the embodiment of the present invention schedules users so that the data rate can guarantee the average rate of the service, and the average rate of the video telephone users is 65 kbps, which ensures the average rate of the service is 64 kbps, and the average rate of the video stream users is 2.1. Mbps guarantees an average rate of 2Mbps for the service. In the PF algorithm, good channel conditions and high instantaneous rate user scheduling are selected, while for the EPF algorithm, the delay service has a greater priority weight, so the data rate of the real-time service is basically unaffected, but for non-real time. Video stream service, scheduling priority is low, so can not choose good channel condition scheduling, so performance is reduced, the average rate is 1.89Mbps, the loss is about 13.7%, can not meet the average rate requirements, and the edge rate is 1.676Mbps, loss It is about 6.9%.
结合上述描述,通过本发明提供的QoS度量算法,除了考虑用户的速率参数外,还考虑时延的QoS特性,导致不完全是最好信道条件和最高的瞬时速率被调度,比较PF算法,性能同样有一定的损失,但对于实时视频电话业务,由于时延是最重要的QoS参数选择大的权值(0.7),所以数据速率基本没有损失,而对于非实时视频流业务,速率是更重要的参数有大的权值,而时延有更小的要求,但仍有一定影响(权值为0.2),所以数据速率有轻微的损失,仅为4%。比较EPF算法,由于非实时业务调度算法中,时延的权值仅为0.2,更大的权值应用在速率QoS特性上,故平均速率性能增加约为11.2%,边缘速率性能增益约为4.7%。可以看出,提出的方法取得QoS时延和速率的平衡,获得更优化的性能。In combination with the above description, the QoS metric algorithm provided by the present invention considers the QoS characteristics of the delay in addition to the rate parameter of the user, resulting in the incomplete best channel condition and the highest instantaneous rate being scheduled, comparing the PF algorithm, performance. There is also a certain loss, but for real-time video telephony services, since the delay is the most important QoS parameter to choose a large weight (0.7), there is basically no loss of data rate, and for non-real-time video streaming services, the rate is more important. The parameters have large weights, while the delay has smaller requirements, but still has some impact (weight 0.2), so the data rate has a slight loss, only 4%. Compared with the EPF algorithm, since the weight of the delay is only 0.2 in the non-real-time service scheduling algorithm, and the larger weight is applied to the rate QoS characteristic, the average rate performance is increased by about 11.2%, and the edge rate performance gain is about 4.7. %. It can be seen that the proposed method achieves a balance between QoS delay and rate to obtain more optimized performance.
此外,为了能够更为直观的了解PF算法、EPF算法、本发明实施例提出的度量算法这三种度量算法的实现效果,现结合上述表1给出的仿真实例,给出三种实现方法的关于速率统计的比较。如下表2所示,统计的内容包括涉及Video streaming业务、Video telephony业务两种业务,比较的对象包括用户平均速率和用户边缘速率,而具体的仿真方法与表1中描述相同,在此不再重复说明,而表示统计结果的数值在上述已描述,在该表2中只是以更为直观的形式将这些统计值或比较值表示出来。In addition, in order to more intuitively understand the implementation effects of the three measurement algorithms of the PF algorithm, the EPF algorithm, and the measurement algorithm proposed by the embodiment of the present invention, the simulation examples given in Table 1 above are given, and three implementation methods are given. A comparison of rate statistics. As shown in Table 2 below, the statistics include the video streaming service and the Video telephony service. The comparison objects include the average user rate and the user edge rate. The specific simulation method is the same as described in Table 1. The description is repeated, and the numerical values representing the statistical results are described above, and in Table 2, these statistical values or comparison values are only expressed in a more intuitive form.
表2Table 2
结合上述三种度量调度算法的说明,以及针对同一具体实例的仿真结果,不难看出,本实施例提出的QoS度量方法通过改变各个QoS参数的权值来表征业务的QoS特性,从而在调度中满足业务的多QoS特性基础上获得优化的系统性能。Combining the descriptions of the above three metric scheduling algorithms and the simulation results for the same specific example, it is not difficult to see that the QoS metric method proposed in this embodiment characterizes the QoS characteristics of the service by changing the weights of the respective QoS parameters, thereby being in the scheduling. Optimized system performance based on the multi-QoS characteristics of the service.
