本发明涉及无线网络技术领域，具体涉及一种LTE载波调度装置及方法。The present invention relates to the technical field of wireless networks, in particular to an LTE carrier scheduling device and method.
背景技术Background technique
随着移动网络的不断发展，用户终端的不断换代升级及运营商提速降费的推进，当前LTE网络负荷的变化呈现出越来越明显的复杂化，但当前现网资源有限，不可能实现每个站点充分扩容，这就需要通过载波资源的调度来适应小区状态的变化，从而在确保用户体验度的前提下充分发挥每一份调度资源的价值，With the continuous development of mobile networks, the continuous upgrading of user terminals and the advancement of operators to increase speed and reduce fees, the current LTE network load changes are becoming more and more complicated. However, the current network resources are limited, and it is impossible to realize every To fully expand the capacity of each site, it is necessary to adapt to the change of the cell status through the scheduling of carrier resources, so as to give full play to the value of each scheduling resource under the premise of ensuring user experience.
现有技术中LTE载波调度的策略包括以下3个步骤：1、调度小区的选择：将现网有辅载波或者多频点共覆盖的载波批量纳入调度小区范畴，以供后续调度使用；2、调度策略的确定：对已纳入调度小区的站点近期的负荷变化进行手动统计分析，人为对调度时间做出选择判定；3、调度策略的执行：根据人为做出的调度策略，在相应时间节点对相应调度小区实施调度策略。也即，首先确定调度小区的范畴，然后手动统计分析其近期负荷的变化情况，根据负荷的变化情况人为判定调度时间，最后被纳入调度范畴的小区根据调取策略在相应时间节点实施相对应的调度。The LTE carrier scheduling strategy in the prior art includes the following three steps: 1. Selection of the scheduling cell: the existing network has auxiliary carriers or carriers covered by multiple frequency points into the scope of the scheduling cell in batches for subsequent scheduling; 2. Determination of scheduling strategy: Manual statistical analysis of the recent load changes of the sites that have been included in the scheduling area, and artificial selection and judgment of scheduling time; 3. Execution of scheduling strategy: According to the scheduling strategy made artificially, at the corresponding time node The corresponding dispatching cell implements the dispatching strategy. That is to say, first determine the scope of the dispatching cell, then manually analyze the recent load changes, manually determine the scheduling time according to the load change, and finally the cells that are included in the scheduling category implement corresponding time nodes according to the call strategy. scheduling.
但是，发明人在实现本发明的过程中发现现有技术至少存在以下不足：1、准确性方面：目前调度策略的决策是基于人工手动对小区近期负荷变化情况的统计分析而做出的，人工操作必然会引起误差，影响调度策略的准确性；2、及时性方面：目前调度策略的调度时长一般以天为单位，且一旦确定调度时长后很少再去更改，但网络的负荷每时每刻都在发生着巨大的变化，负荷变化不明显的时候需要延长调度时长、反之则需要缩短调度周期以更快速的适应负荷变化，因此目前的调度策略在应对小区负荷变化的及时性方面也略显不足；3、节能性方面：当前的调度策略是一旦某站点被执行调度指令，该站点下所有的调度小区均被批量调度，但有时候小区状态波动不大，仅需调度少量小区即可满足小区负荷的变化，批量的调度反而会造成资源的浪费。However, the inventor found that the prior art has at least the following deficiencies in the process of realizing the present invention: 1. In terms of accuracy: the decision-making of the current scheduling strategy is based on manual statistical analysis of the recent load changes in the community. The operation will inevitably cause errors and affect the accuracy of the scheduling strategy; 2. Timeliness: the scheduling duration of the current scheduling strategy is generally in days, and once the scheduling duration is determined, it is rarely changed, but the network load is Huge changes are taking place all the time. When the load changes are not obvious, the scheduling duration needs to be extended, and vice versa, the scheduling cycle needs to be shortened to adapt to the load changes more quickly. Therefore, the current scheduling strategy is not as good as the timeliness of responding to the load changes in the community. Insufficient; 3. In terms of energy saving: the current scheduling strategy is that once a site is executed a scheduling command, all the scheduling cells under the site will be scheduled in batches, but sometimes the status of the cells does not fluctuate much, and only a small number of cells need to be scheduled. To meet the change of cell load, batch scheduling will cause waste of resources.

计算模块22，适于根据小区状态信息计算采样周期内的小区平均拥塞度。The calculation module 22 is adapted to calculate the average congestion degree of the cell within the sampling period according to the state information of the cell.
具体地，计算模块通过执行以下几个步骤来小区平均拥塞度：Specifically, the calculation module calculates the cell average congestion degree by performing the following steps:
步骤1，根据eNODEB采集的小区状态信息，计算该eNODEB下单个小区拥塞度Ωi；Step 1, according to the cell status information collected by the eNODEB, calculate the congestion degree Ωi of a single cell under the eNODEB;
步骤2，计算采样周期内小区的平均拥塞度其中x表示第x次采样周期。Step 2, calculate the average congestion degree of the cell within the sampling period Where x represents the xth sampling period.

其中，小区状态波动数据px为小区平均拥塞度与小区历史平均拥塞度的差值与小区历史平均拥塞度/>的商，具体计算公式如下：Among them, the cell state fluctuation data px is the average congestion degree of the cell Compared with the historical average congestion degree of the cell The difference between the difference and the average congestion degree of the cell history/> The specific calculation formula is as follows:
然后，对小区状态波动数据px进行鲁棒函数校验，初步获得本次需调度的小区数量Then, perform a robust function check on the cell state fluctuation data px to initially obtain the number of cells to be scheduled this time
其中，y＝{yi|i＝1,…,w}是用户可以自行设定的鲁棒校验系数，用以表征站点下小区波动状态的敏感度。Wherein, y={yi |i=1,...,w} is a robust calibration coefficient that can be set by the user to represent the sensitivity of the fluctuating state of the cell under the site.
决策模块24，适于将初始调度小区数量与可调度小区数量进行比较，根据比较结果确定目标调度小区数量。The decision module 24 is adapted to compare the number of initially scheduled cells with the number of schedulable cells, and determine the target number of scheduled cells according to the comparison result.
将初步获得的调度小区数量同目前站下可调度的小区数量做比较，根据比较结果决策出最终的调度小区数量Φx。The number of scheduling cells that will be initially obtained Compared with the number of cells that can be dispatched under the current station, the final number of dispatched cells Φx is decided according to the comparison result.
具体地，若初始调度小区数量小于或等于0，则确定目标调度小区数量为初始调度小区数量与激活态调度组小区数量的负值之间的最大值；若初始调度小区数量大于0，则确定目标调度小区数量为初始调度小区数量与总调度组小区数量和激活态调度组小区数量的差值之间的最大值。公式表示如下：Specifically, if the number of initial scheduling cells is less than or equal to 0, then determine that the number of target scheduling cells is the maximum value between the number of initial scheduling cells and the negative value of the number of cells in the active scheduling group; if the number of initial scheduling cells is greater than 0, then determine The number of target scheduling cells is the maximum value between the number of initial scheduling cells and the difference between the number of cells in the total scheduling group and the number of cells in the active scheduling group.

若则/>like Then />
若则/>like Then />

例如，若Φx＝-1，则激活1个调度小区，若Φx＝2，则激活2个未激活的调度小区。For example, if Φx =-1, one scheduling cell is activated, and if Φx =2, two inactive scheduling cells are activated.
第一更新模块26，适于根据目标调度小区数量对采样周期的时长进行更新，通过更新动态采样周期，能够更好地适应小区的状态变化。The first update module 26 is adapted to update the duration of the sampling period according to the number of target scheduled cells, and by updating the dynamic sampling period, it can better adapt to the state changes of the cells.
具体地，若目标调度小区数量为零，则按照周期延长规则延长采样周期的时长，如果最终确定的需要调度的小区数量为零，说明小区当前鲁棒性较好，为了节省空口资源，可以对采样周期进行延长，下一次调度时按照延长的采样周期采集数据进行调度处理。一种可选的计算公式如下：Specifically, if the number of cells to be scheduled is zero, then the sampling period is extended according to the cycle extension rule. If the number of cells that need to be scheduled is finally determined to be zero, it means that the current robustness of the cell is good. In order to save air interface resources, you can use The sampling period is extended, and the next scheduling will collect data according to the extended sampling period for scheduling processing. An optional calculation formula is as follows:
下一次采样周期＝min{当前采样周期+15分钟，60分钟}Next sampling period = min{current sampling period+15 minutes, 60 minutes}
若目标调度小区数量不为零，则按照周期缩短规则缩短采样周期的时长，若最终确定的需要调度的小区数量为零，说明小区当前鲁棒性较差，为了更快速地适应小区的状态变化，需要缩短采样周期，下一次采样时按照延长的采样周期采集数据进行调度处理。一种可选的计算公式如下：If the number of target scheduling cells is not zero, shorten the sampling period according to the cycle shortening rule. If the number of cells that need to be scheduled is finally determined to be zero, it means that the current robustness of the cell is poor. In order to adapt to the state changes of the cell more quickly , the sampling period needs to be shortened, and the next sampling will collect data according to the extended sampling period for scheduling and processing. An optional calculation formula is as follows:
下一次采样周期＝max{当前采样周期-|Φx|*15分钟，15分钟}The next sampling period = max{current sampling period-|Φx |*15 minutes, 15 minutes}
由此可见，本实施例的装置通过更新动态采样周期，能够更好地适应小区的状态变化。It can be seen that, by updating the dynamic sampling period, the apparatus of this embodiment can better adapt to the state change of the cell.

According to the cell average congestion degree in the sampling period is included in the cell history congestion degree, the current cell history average congestion degree is updated, and the updated cell history average congestion degree is used as a reference for scheduling processing in the next sampling period.
由此可见，通过采集小区状态信息，装置自行计算所有调度站点的小区拥塞度，用来进行鲁棒函数的校验，整个过程由装置自动执行完成，避免了人工参与，提升了调度的准确性。其次，将小区周期内的平均拥塞度与历史拥塞度做比较，得出小区周期内的波动，并引入鲁棒函数进行校验，判决出需要调度的小区数，相比传统的批量调度，提高了算法的精准性，节能性；另外，装置根据鲁棒函数校验的结果来评估小区当前的鲁棒性，并以此来增加或减少采样周期，从而更好更快速的适应小区状态的变化，提高了调度的及时性。It can be seen that, by collecting cell status information, the device calculates the cell congestion degree of all dispatching sites by itself, which is used to verify the robust function. The entire process is automatically executed by the device, which avoids manual participation and improves the accuracy of dispatching. . Secondly, compare the average congestion degree in the cell cycle with the historical congestion degree to get the fluctuation in the cell cycle, and introduce a robust function for verification, and determine the number of cells that need to be scheduled. Compared with traditional batch scheduling, it improves In addition, the device evaluates the current robustness of the cell according to the results of the robust function verification, and increases or decreases the sampling period, so as to adapt to changes in the state of the cell better and faster , improving the timeliness of scheduling.

具体地，若目标调度小区数量为零，则按照周期延长规则延长采样周期的时长，如果最终确定的需要调度的小区数量为零，说明小区当前鲁棒性较好，为了节省空口资源，可以对采样周期进行延长，下一次采样时按照延长的采样周期采集数据进行调度处理。Specifically, if the number of cells to be scheduled is zero, then the sampling period is extended according to the cycle extension rule. If the number of cells that need to be scheduled is finally determined to be zero, it means that the current robustness of the cell is good. In order to save air interface resources, you can use The sampling period is extended, and the next sampling will collect data according to the extended sampling period for scheduling and processing.
若目标调度小区数量不为零，则按照周期缩短规则缩短采样周期的时长，若最终确定的需要调度的小区数量为零，说明小区当前鲁棒性较差，为了更快速地适应小区的状态变化，需要缩短采样周期，下一次采样时按照延长的采样周期采集数据进行调度处理。If the number of target scheduling cells is not zero, shorten the sampling period according to the cycle shortening rule. If the number of cells that need to be scheduled is finally determined to be zero, it means that the current robustness of the cell is poor. In order to adapt to the state changes of the cell more quickly , the sampling period needs to be shortened, and the next sampling will collect data according to the extended sampling period for scheduling and processing.
在一种可选的方式中，方法进一步包括：根据本采样周期内的小区平均拥塞度对小区历史平均拥塞度进行更新。根据采样周期内的小区平均拥塞度纳入到小区历史拥塞度中，对当前的小区历史平均拥塞度进行更新，更新后的小区历史平均拥塞度作为在下一个采样周期内进行调度处理的参照。In an optional manner, the method further includes: updating the historical average congestion degree of the cell according to the average congestion degree of the cell in the current sampling period.
