As an optional way, the similarity between the current service capacity index and the historical service capacity index can be obtained, and then the prediction result is obtained according to the similarity. Since the prediction method is based on the similarity, the prediction can be made more accurate.
在进行相似度预测的时候，可以从数值的角度来得到相似度，此时就需要将业务容量指标转换为一系列的数据。在本实施例中提供了一种可选的实施方式，在该可选的实施方式中，将业务容量指标转换成了序列数据，这些序列数据中包括了多个数据，多个数据中的每一个数据对应一种进行预定业务的预定类型的终端在某个时刻对应的业务容量。When performing similarity prediction, the similarity can be obtained from a numerical perspective. At this time, it is necessary to convert the service capacity index into a series of data. An optional implementation is provided in this embodiment. In this optional implementation, the service capacity index is converted into sequence data, and these sequence data include multiple data, and each of the multiple data One piece of data corresponds to the service capacity corresponding to a predetermined type of terminal performing predetermined services at a certain moment.
在该可选实施方式中，在进行预测的时候，可以首先获取当前时刻的业务容量指标对应的第一序列数据和历史的业务容量指标对应的第二序列数据。由于得到的数据序列包括了多个数据，此时可以根据该多个数据构建第一序列数据对应的第一雷达图和第二序列数据对应的第二雷达图；然后，再根据第一雷达图和第二雷达图重叠率得到相似度。In this optional implementation manner, when forecasting, the first sequence data corresponding to the service capacity index at the current moment and the second sequence data corresponding to the historical service capacity index may be acquired first. Since the obtained data sequence includes a plurality of data, the first radar map corresponding to the first sequence data and the second radar map corresponding to the second sequence data can be constructed according to the multiple data; then, according to the first radar map The similarity is obtained from the overlapping ratio of the second radar map.

步骤S202，采集服务小区及其相邻小区的各种业务容量，例如，VoLTE终端VoLTE业务、VoLTE终端数据业务、VoLTE终端话音业务、空载VoLTE终端、非VoLTE终端数据业务、非VoLTE终端语音业务和空载非VoLTE终端容量，并形成分类容量时间序列矩阵，如表1所示：Step S202, collect various service capacities of the serving cell and its adjacent cells, for example, VoLTE terminal VoLTE service, VoLTE terminal data service, VoLTE terminal voice service, unloaded VoLTE terminal, non-VoLTE terminal data service, non-VoLTE terminal voice service and no-load non-VoLTE terminal capacity, and form a classified capacity time series matrix, as shown in Table 1:
表1小区分类容量时间序列矩阵Table 1 Time series matrix of community classification capacity
其中Cap(i,0,volte)括号内的3个标号分别代表时刻，终端类型(VoLTE终端、非VoLTE终端)和业务类型(VoLTE、data、voice和none)，如Cap(i,0,volte)代表第i时刻，VOLTE终端产生的VoLTE业务容量，Cap(i,1,data)为i时刻非VoLTE终端产生数据业务容量；The three labels in the brackets of Cap(i,0,volte) represent time, terminal type (VoLTE terminal, non-VoLTE terminal) and service type (VoLTE, data, voice and none), such as Cap(i,0,volte ) represents the VoLTE service capacity generated by the VOLTE terminal at the i-th moment, and Cap(i,1,data) is the data service capacity generated by the non-VoLTE terminal at the i moment;
步骤S204,与步骤S202类似，获取当前时刻服务小区及相邻小区的容量指标Cap(0,0,volte),Cap(0,0,data),Cap(0,0,voice),Cap(0,0,none),Cap(0,1,data),Cap(0,1,voice)和Cap(0,1,none)Step S204, similar to step S202, obtains capacity indicators Cap(0,0,volte),Cap(0,0,data),Cap(0,0,voice),Cap(0 ,0,none),Cap(0,1,data),Cap(0,1,voice) and Cap(0,1,none)
步骤S206：以步骤S202和步骤S204采集的序列数据构建当前时刻0和历史时刻i的业务容量雷达图，如图3所示，并计算将两者的重叠率Oi0作为其相似度，其中重叠率的计算如公式1所示：Step S206: Use the sequence data collected in steps S202 and S204 to construct a traffic capacity radar map at current time 0 and historical time i, as shown in Figure 3, and calculate the overlap rate Oi0 of the two as their similarity, where the overlap rate The calculation of is shown in Equation 1:
步骤S208：按照步骤S206，计算第i时刻服务小区及其相邻小区k的雷达图的重叠率Oik(Oik为第k个相邻小区当前时刻与第i时刻的容量相似度)；Step S208: according to step S206, calculate the overlap rate Oik of the radar image of serving cell and its adjacent cell k at the i moment (Oik is the capacity similarity between the kth adjacent cell at the current moment and the i moment);
步骤S210：按照公式2计算第i时刻的N个小区容量相似度:Step S210: Calculate the capacity similarities of the N cells at the i-th moment according to formula 2:
将该相似度最大的时刻i的容量，作为预测容量，其预测值为Cap(exp,0,volte),Cap(exp,0,data),Cap(exp,0,voice),Cap(exp,0,none),Cap(exp,1,data),Cap(exp,1,voice)和Cap(exp,1,none)。The capacity at time i with the highest similarity is taken as the predicted capacity, and its predicted values are Cap(exp,0,volte),Cap(exp,0,data),Cap(exp,0,voice),Cap(exp, 0,none), Cap(exp,1,data), Cap(exp,1,voice) and Cap(exp,1,none).
在根据上述实施例中的方案得到预测的业务容量之后，在一个可选的实施例中，可以参考业务容量的最大值来确定如何进行调整。After the predicted service capacity is obtained according to the solutions in the foregoing embodiments, in an optional embodiment, how to make adjustments may be determined by referring to the maximum value of the service capacity.
例如，可以根据小区的预测的VoLTE的业务容量与该小区的VoLTE的业务容量的最大值，确定是否对参数进行调整。For example, it may be determined whether to adjust the parameters according to the predicted VoLTE service capacity of the cell and the maximum value of the VoLTE service capacity of the cell.
由于业务容量的最大值是衡量一个小区业务处理能力的比较优的一个参考值，所以，至少根据该最大进行调整，可以使调整更加准确。在实际进行通信的时候，可以调整的参数有很多种，此时可以根据实际的需要来进行调整。Since the maximum value of the service capacity is a relatively good reference value for measuring the service processing capability of a cell, at least adjusting according to the maximum value can make the adjustment more accurate. In actual communication, there are many parameters that can be adjusted, which can be adjusted according to actual needs.
例如，确定是否对参数进行调整包括以下至少之一：在服务小区的业务容量预测结果小于服务小区的VoLTE业务容量最大值的第一预定比例的情况下，不对通信参数进行调整；在服务小区的业务容量预测结果大于或等于服务小区的VoLTE业务容量最大值的第一预定比例并且小于服务小区的VoLTE业务容量最大值的第二预定比例的情况下，进行以下调整：提高服务小区的PDCCH下行功率、PDSCH下行功率、和PUSCH上行功率；降低服务小区的相邻小区的TCH功率和BCCH功率，其中第二预定比例大于第一预定比例；并且在服务小区的业务容量预测结果大于或等于服务小区的VoLTE业务容量最大值的第二预定比例的情况下，调整切换门限以将服务小区的VoLTE业务引导至服务小区的相邻小区。For example, determining whether to adjust the parameters includes at least one of the following: when the service capacity prediction result of the serving cell is less than the first predetermined ratio of the VoLTE service capacity maximum value of the serving cell, the communication parameters are not adjusted; When the service capacity prediction result is greater than or equal to the first predetermined proportion of the maximum VoLTE service capacity of the serving cell and less than the second predetermined proportion of the maximum VoLTE service capacity of the serving cell, the following adjustments are made: increase the PDCCH downlink power of the serving cell , PDSCH downlink power, and PUSCH uplink power; reduce the TCH power and BCCH power of the adjacent cell of the serving cell, wherein the second predetermined ratio is greater than the first predetermined ratio; and the traffic capacity prediction result of the serving cell is greater than or equal to that of the serving cell In the case of a second predetermined ratio of the maximum value of the VoLTE service capacity, the handover threshold is adjusted to guide the VoLTE service of the serving cell to an adjacent cell of the serving cell.
下面结合图4对参数调整的示例性步骤进行说明。Exemplary steps of parameter adjustment will be described below with reference to FIG. 4 .
在预测小区及其相邻小区的各类业务容量后，通过动态调整切换门限、功率控制和波束赋形参数，确保VoLTE终端覆盖和VoLTE业务的SINR需求。After predicting the various service capacities of the cell and its adjacent cells, dynamically adjust the handover threshold, power control, and beamforming parameters to ensure the coverage of VoLTE terminals and the SINR requirements of VoLTE services.
步骤S402，若某小区的Cap(exp,0,volte)<MaxCap*60％(MaxCap为本小区VoLTE业务容量最大值，在激活RoHC配置的情况下，若VoLTE业务为高清VoLTE，则Maxcap＝288，若VoLTE业务为标清VoLTE时，Maxcap＝576)时，切换门限、功控和波束赋形参数不做调整，VoLTE业务直接接入，否则转入步骤S404；Step S402, if Cap(exp, 0, volte)<MaxCap*60% of a certain cell (MaxCap is the maximum value of the VoLTE service capacity of this cell, in the case of activating RoHC configuration, if the VoLTE service is high-definition VoLTE, then Maxcap=288 , if the VoLTE service is standard-definition VoLTE, Maxcap=576), the handover threshold, power control and beamforming parameters are not adjusted, and the VoLTE service is directly connected, otherwise proceed to step S404;
步骤S404，若某小区的Cap(exp,0,volte)>＝MaxCap*60％，Cap(exp,0,volte)<MaxCap*80％，Cap(exp,0,volte)－Cap(0,0,volte)>0，将PDCCH和PDSCH的下行功率调高3dB，同时指示终端启动功率控制将PUSCH上行功率调高3dB，于此同时将3G相邻小区的TCH和BCCH功率降低3dB，一方面提升VoLTE的覆盖范围，另一方面降低VoLTE业务启用CSFB回落到CS域，或语音业务切换至eSRVCC的切换概率；Step S404, if Cap(exp,0,volt)>=MaxCap*60% of a certain cell, Cap(exp,0,volte)<MaxCap*80%, Cap(exp,0,volte)-Cap(0,0 ,volte)>0, increase the downlink power of PDCCH and PDSCH by 3dB, and at the same time instruct the terminal to start power control to increase the uplink power of PUSCH by 3dB, and at the same time reduce the TCH and BCCH power of 3G adjacent cells by 3dB. The coverage of VoLTE, on the other hand, reduces the switching probability of VoLTE business enabling CSFB to fall back to CS domain, or switching voice business to eSRVCC;
步骤S406，若某小区的Cap(exp,0,volte)>＝MaxCap*80％，且Cap(exp,0,volte)－Cap(0,0,volte)>0，本方法将调整切换门限A1至-115dB，并将VoLTE业务导引切换至其他相邻小区，备选相邻小区优先选择容量满足Cap(exp,0,volte)<MaxCap*60％的相邻小区。Step S406, if Cap(exp,0,volt)>=MaxCap*80% of a certain cell, and Cap(exp,0,volt)-Cap(0,0,volt)>0, this method will adjust the handover threshold A1 to -115dB, and guide the VoLTE service to be switched to other neighboring cells, and the candidate neighboring cells are preferentially selected as neighboring cells whose capacity satisfies Cap(exp,0,volte)<MaxCap*60%.
在得到预测的业务容量之后，在另一个实施例中，还可以调整进行VoLTE业务的资源和/或进行非VoLTE业务的资源。After obtaining the predicted service capacity, in another embodiment, resources for performing VoLTE services and/or resources for performing non-VoLTE services may also be adjusted.
例如，调整进行VoLTE业务的资源和/或进行非VoLTE业务的资源可以包括：根据服务小区和N个相邻小区的当前时刻的业务容量指标和历史时刻的业务容量指标计算所有业务容量指标的最小值、最大值、均值和方差值；根据服务小区的VoLTE业务容量指标的最小值预留用于服务小区的VoLTE业务的资源块，作为预留业务容量；在预留业务容量小于预定值并且服务小区的VoLTE业务量大于预留业务容量情况下，继续为服务小区的VoLTE业务分配资源块，拒绝为VoLTE终端所产生的普通语音业务分配资源块，并将普通语音业务重定向至VoLTE业务量较小的相邻小区中；并且在服务小区的VoLTE业务量大于预定值的情况下，拒绝为服务小区的VoLTE业务分配资源块，并将服务小区的VoLTE业务重定向至VoLTE业务量较小的相邻小区。For example, adjusting resources for VoLTE services and/or resources for non-VoLTE services may include: calculating the minimum value of all service capacity indicators according to the service capacity indicators at the current moment and the service capacity indicators at historical moments of the serving cell and N neighboring cells value, maximum value, mean value and variance value; according to the minimum value of the VoLTE service capacity index of the serving cell, resource blocks reserved for the VoLTE service of the serving cell are used as the reserved service capacity; when the reserved service capacity is less than the predetermined value and When the VoLTE business volume of the serving cell is greater than the reserved business capacity, continue to allocate resource blocks for the VoLTE business of the serving cell, refuse to allocate resource blocks for ordinary voice services generated by VoLTE terminals, and redirect ordinary voice services to VoLTE traffic In a smaller adjacent cell; and when the VoLTE traffic of the serving cell is greater than a predetermined value, refuse to allocate resource blocks for the VoLTE traffic of the serving cell, and redirect the VoLTE traffic of the serving cell to a smaller VoLTE traffic Neighboring district.
下面结合图5对资源分配的示例性步骤进行说明。Exemplary steps of resource allocation are described below with reference to FIG. 5 .
在对参数调整之后，VoLTE终端的VoLTE覆盖得到最大限度的保证，但并不意味着VoLTE业务的容量及稳定性达到最佳，可以进一步根据容量预测结果系统地协同调整VoLTE业务及其他业务资源分配，以保证VoLTE业务的稳定性，降低掉线率。After adjusting the parameters, the VoLTE coverage of VoLTE terminals is guaranteed to the maximum extent, but it does not mean that the capacity and stability of VoLTE services are optimal. Further, the resource allocation of VoLTE services and other services can be systematically adjusted according to the capacity prediction results. , to ensure the stability of VoLTE services and reduce the drop rate.
步骤S502，基于上述的时间序列，得到各小区及其相邻小区的各类业务容量的最小值Cap(min,0,volte)k、均值Cap(avg,0,volte)k、最大值Cap(max,0,volte)k和方差Cap(sqr,0,volte)k；Step S502, based on the above time series, obtain the minimum value Cap(min,0,volte)k, the average value Cap(avg,0,volte)k, and the maximum value Cap( max,0,volte)k and variance Cap(sqr,0,volte)k;
步骤S504，为保证VoLTE业务的稳定性，按Min(Cap(max,0,volte)k)预留VoLTE业务容量的PRB，预留的PRB数量满足公式3：Step S504, in order to ensure the stability of the VoLTE service, reserve PRBs for the VoLTE service capacity according to Min(Cap(max,0,volt)k), and the number of reserved PRBs satisfies Formula 3:
[Min(Cap(max,0,volte)k)*(1.1～1.5)]/[20(TTI)*Min(Cap(max,0,volte)k)/Cap(max,0,volte)k](公式3)；[Min(Cap(max,0,volt)k)*(1.1～1.5)]/[20(TTI)*Min(Cap(max,0,volt)k)/Cap(max,0,volt)k] (Formula 3);
步骤S506,若进入小区的VoLTE业务容量大于预留业务容量Min(Cap(max,0,volte)k),但预留业务量小于200时，继续为VoLTE分配PRB，PRB系数由1.5增加2，同时拒绝为VoLTE终端产生的普通语音业务分配资源，将其重定向至VoLTE业务容量较小的相邻小区；否则进入步骤S508；Step S506, if the VoLTE service capacity entering the cell is greater than the reserved service capacity Min(Cap(max,0,volt)k), but the reserved service volume is less than 200, continue to allocate PRBs for VoLTE, and the PRB coefficient is increased by 2 from 1.5, Simultaneously refuse to allocate resources for the ordinary voice service generated by the VoLTE terminal, and redirect it to an adjacent cell with a smaller VoLTE service capacity; otherwise enter step S508;
步骤S508,若接入小区的VoLTE业务容量>200时，则拒绝继续为其分配PRB资源，将其重定向至VoLTE业务容量较小相邻小区。Step S508, if the VoLTE service capacity of the access cell is >200, refuse to continue to allocate PRB resources to it, and redirect it to an adjacent cell with a smaller VoLTE service capacity.
上述步骤S202-S210、步骤S402至步骤S406、步骤S502至步骤S508可以作为一个实施例来进行实施，图6是根据本发明实施例的另一可选的VoLTE业务处理方法的流程图，如图6所示，该流程可以包括如下步骤：The above steps S202-S210, step S402 to step S406, and step S502 to step S508 can be implemented as an embodiment. FIG. 6 is a flowchart of another optional VoLTE service processing method according to an embodiment of the present invention, as shown in FIG. 6, the process may include the following steps:
步骤S601，采集当前时刻与历史时刻的业务容量序列，计算相似度，以此预测将来业务容量；Step S601, collect the business capacity sequence at the current time and the historical time, and calculate the similarity, so as to predict the future business capacity;
步骤S602，基于业务容量预测值，调整切换门限、功控以及赋形参数以保证VoLTE无线覆盖及SINR指标；Step S602, based on the service capacity prediction value, adjust the handover threshold, power control and shaping parameters to ensure VoLTE wireless coverage and SINR indicators;
步骤S603，在步骤S601和步骤S602的基础上，进一步协调本小区及相邻小区的资源分配，从系统角度保证VoLTE业务容量的连续性和稳定性。Step S603, on the basis of steps S601 and S602, further coordinate the resource allocation of the local cell and adjacent cells, and ensure the continuity and stability of the VoLTE service capacity from the perspective of the system.
通过上述实施例及可选的实施方式，可以取得如下技术效果：Through the above embodiments and optional implementation modes, the following technical effects can be obtained:
VoLTE容量预测：借助服务小区及相邻小区的在线终端情况及终端能力建立VoLTE话务模型，对VoLTE容量进行预测，作为VoLTE无线网覆盖和资源分配参数调整的依据；VoLTE capacity prediction: establish a VoLTE traffic model based on the online terminal conditions and terminal capabilities of the serving cell and adjacent cells, and predict the VoLTE capacity as the basis for adjusting VoLTE wireless network coverage and resource allocation parameters;
覆盖参数优化：VoLTE承载的语音业务不仅对时延有较高要求，对BLER等要求也较一般的数据业务要求高，对SINR比较比普通数据业务高3dB左右，对无线网络覆盖产生了更高要求，既要保证上下行RSRP的信号覆盖，又要避免因信号增强对其他用户的影响；Coverage parameter optimization: Voice services carried by VoLTE not only have higher requirements on delay, but also have higher requirements on BLER than general data services. The SINR is about 3dB higher than that of ordinary data services, which has higher wireless network coverage. Requirements, not only to ensure the signal coverage of uplink and downlink RSRP, but also to avoid the impact on other users due to signal enhancement;
资源协同分配：VoLTE使用的是数据通道，在进行PRB分配时，一方面需要考虑同一终端VoLTE和其他数据业务并存情况下的分配，另一方面需要考虑与非VoLTE终端共存情况下的资源分配，降低终端接受信号强但无法接通VoLTE业务的概率。Resource coordination allocation: VoLTE uses data channels. When performing PRB allocation, on the one hand, it is necessary to consider the allocation of the same terminal VoLTE and other data services, and on the other hand, it is necessary to consider resource allocation in the case of coexistence with non-VoLTE terminals. Reduce the probability that the terminal receives a strong signal but cannot connect to the VoLTE service.
