- CCO Coverage Control Operator
- CCO allows the system to adapt to changes in traffic (i.e., load and location) and radio environment by automatically adjusting cell coverage. Issues related to CCO function detection include:
- MRO Mobility Robustness Optimization
- Mobility Load Balancing primarily handles inter-frequency load distribution scenarios. CCO, however, should address the situation where UEs are at the cell/beam edge, where "edge" refers to cells/beams utilizing the same resources.
- coverage and capacity optimization typically involves first identifying problems and then resolving them. For example, if coverage holes or cell edge interference are detected, the base station/OAM (Operational Management Center) formulates strategies to address these issues.
- Each NG-RAN node can choose optional coverage configurations for its OAM.
- an NG-RAN node detects a coverage problem or receives a CCO (Content Control Order) configuration adjustment notification from a neighboring NG-RAN node, it will automatically adjust its CCO configuration. After adjusting its coverage configuration, the NG-RAN node can provide the results to neighboring NG-RAN nodes, allowing them to make corresponding adjustments.

- AI/ML technology can be used to predict cell capacity and coverage issues in NG-RAN nodes and infer corresponding adjustment strategies.

- Base station 1 triggers a decision to adjust its coverage configuration (from configuration 1 to configuration 2). After the coverage configuration of base station 1 is adjusted, it will notify neighboring stations that its coverage configuration has been adjusted through the NG-RAN NODE CONFIGURATION UPDATE message. The neighboring stations adjust their own coverage according to the adjusted coverage configuration information.
- FIG. 2 is another schematic diagram of traffic hotspots at the cell edge. If the coverage area is reduced as shown in Figure 2, it may cause a large number of UEs in the traffic hotspots to trigger reselection/switching from base station 1 to base station 2, which will have a certain impact on users and cause a large number of UEs to experience service interruption in a short period of time.
- base station 1 can notify base station 2 of the cell coverage to be modified during the next reconfiguration by sending an NG-RAN NODE CONFIGURATION UPDATE message and setting a pre-change notification for the cell deployment status. However, it still does not notify when the coverage information will be modified. Base station 1 still needs to modify the coverage before notifying the neighboring station that its coverage has been modified.

To ensure that the coverage configuration modification time is consistent, this time information can be represented by UTC time.
- the reason for modifying the coverage configuration may be: whether a coverage problem is about to occur, or a capacity problem at the cell edge.
- the neighboring station receives the first prediction information and infers the corresponding modification of its own coverage configuration based on the predicted modification of the coverage configuration.

- the base station Before modifying the coverage configuration in step 2, the base station records/acquires/stores the UE performance information before the coverage configuration modification and marks the coverage configuration in which the performance information is located; after the coverage configuration modification is completed, the UE performance information is collected again, and the performance before and after the coverage configuration modification is compared to determine whether there is performance degradation; furthermore, the base station can specify to record the performance information of a specific UE; for information such as measurement reports obtained from the UE, the base station sets a reporting time threshold, and after the reporting time threshold is reached, or after the UE has completed reporting the measurement report, the current base station modifies the CCO configuration; in the case of performance degradation, the above coverage configuration modification process is repeated to modify the coverage configuration information for optimization.

- the UE performance information in 1) can be obtained by the base station sending a request message to the UE, requesting the UE to report the existing measurement report, and setting a reporting time threshold.

CCO是无线接入网络的优化方式之一,是自优化网络的典型用例。CCO功能的主要目的是检测并解决覆盖或者容量问题,如:弱覆盖、覆盖空洞等场景,其中,覆盖与容量的优化之间存在权衡,对于容量的增强通常以覆盖范围缩小为代价,反之依然。因此,对于覆盖与容量的优化需要平衡这两个关键因素。
CCO允许系统通过自动调整小区的覆盖范围,适应流量(即负载和位置)和无线电环境的变化。CCO功能检测的问题包括:
1、覆盖问题:
覆盖问题关注的是参考信号的覆盖不是最优,使得终端性能下降的场景,如:覆盖空洞、上行链路(UpLink,UL)或下行链路(Downlink,DL)覆盖不匹配等。值得注意的是,在一个具有良好小区规划的网络中,移动健壮性优化(Mobility Robustness Optimisation,MRO)将处理由于移动性设置有问题而导致的所有类型的故障问题。而CCO应解决由于不合适的覆盖规划导致的故障问题。
2.容量问题:
在小区或波束容量饱和的情况下,会导致一个或多个UE出现性能不佳的情况,造成这种情况的原因有很多,如:业务的高需求超过了小区/波束的可用资源、无线环境过于恶劣,影响了大量UE(大量UE位于小区边缘,对其他UE造成高干扰并消耗大量资源)。值得注意的是,移动负载均衡(Mobility Load Balancing,MLB)主要处理频率间(inter frequency)的负载分配场景。而CCO应解决UE在小区/波束边缘的情况,其中“边缘”是利用相同资源的小区/波束之间。
相关技术中,对于覆盖与容量优化通常是先发现问题,再解决问题,如:检测到出现覆盖空洞、小区边缘干扰等问题,然后基站/OAM制定策略解决检测到的问题。每个NG-RAN节点可以选择OAM配置可选的覆盖配置,当某个NG-RAN节点检测到覆盖问题或收到邻NG-RAN节点的CCO配置调整通知时,会自行调整CCO配置。NG-RAN节点调整覆盖配置后,可将调整结果提供给相邻NG-RAN节点,这样,相邻的NG-RAN节点也可以进行相应的调整。但在这种机制下,无法提前预测和避免覆盖与容量问题。
相关CCO机制的性能可以通过AI/ML技术进一步提高。AI/ML技术可用于预测NG-RAN节点的小区容量和覆盖问题,并推断相应的调整策略。
对于小区边缘用户,为提升边缘用户吞吐量,会尽量提高UE UL发射功率,UL发射功率提高后势必对邻区造成UL干扰。而当小区边缘存在流量热点时,此类问题可能会更严重。
如图1所示,图1为小区边缘存在流量热点的示意图;当基站1检测到小区边缘存在流量热点后,发现当前基站的覆盖配置存在小区边缘干扰问题需要解决,基站1触发决策,对基站1的覆盖配置进行调整(从配置1调整为配置2),基站1的覆盖配置调整后,会通过NG-RAN NODE CONFIGURATION UPDATE消息通知邻站其覆盖配置已调整,邻站根据调整的覆盖配置信息调整自身的覆盖。
然而,在覆盖配置调整过程中,由于目前是在发现小区边缘干扰问题后才进行问题解决的,若此时基站1的容量已趋于极限,如图1中再扩大覆盖范围,对基站1的容量也是一种挑战;图2为又一种小区边缘存在流量热点的示意图;若如图2一样缩小覆盖范围,则可能会导致流量热点中大量的UE会触发从基站1重选/切换到基站2,对用户产生一定的影响,使得短时间内大量UE的业务中断。
相关技术中,基站1可以通过发送NG-RAN NODE CONFIGURATION UPDATE消息,并设置小区部署状态的预先变更通知来通知基站2,下次重配会修改的小区覆盖,但仍未通知何时会修改覆盖信息,仍需要基站1覆盖修改后再通知邻站其覆盖已修改,该内容可以结合图3和图4进行理解,图3为小区部署状态的预先变更参数的示意图;图4为小区部署状态的预先变更的示意图;因此,会存在如图4中的出现覆盖空洞的短暂中间状态。
基于此,在对覆盖与容量优化方面,考虑先预测覆盖与容量问题,提前修改基站覆盖配置,并在基站间及时同步覆盖配置修改信息,可以实现更优的覆盖与容量优化,减少覆盖问题、小区边缘干扰问题的发生概率。

本公开提出一种AI/ML辅助的覆盖与容量优化方法,提前预测并解决覆盖与容量问题,减少覆盖问题、小区边缘干扰问题对用户的影响。具体步骤如下:
1.基站新增接收第一信息,第一信息用于指示基站的覆盖与容量相关信息,和UE及流量的分布信息。
具体地,
1)基站获取邻站的第一信息,用于判断覆盖配置是否需要调整,第一信息可包含如下信息的一项或多项:
邻基站的覆盖配置;
邻基站的UE分布及其对应流量;
邻基站的资源使用情况;
邻基站的失败事件及其对应的RLF报告等;
邻基站成功事件及对应的报告,如:RA报告、SHR报告等;
邻基站小区负载。
2)其中,1)中所述的第一信息,通过如下方式获得:
方式一:当基站1发出请求时,基站2发送请求的相应信息给基站1;
方式二:基站2在配置更新时,直接通过NG-RAN NODE CONFIGURATION UPDATE发送配置更新的时候,新增携带覆盖配置相关信息到基站1。
3)基站获取第一信息后,在基站侧存储,并为每项信息标记时间信息,以用作AI模型训练/推断的输入信息;
4)第一信息可为当前测量的数据,也可为AI预测的数据,具体看基站1发出请求消息中携带的请求信息;
2.基于1的第一信息,基站可获取第一预测信息,并在基站间交互第一预测信息,第一预测信息用于指示基站即将变化的覆盖配置方案相关信息,其中,第一预测信息可包括时间信息,用于指示当前基站、邻站的覆盖配置修改时间;或邻站可根据第一预测信息,判断其本身的覆盖范围是扩大还是缩小,优先变动覆盖范围扩大的覆盖配置,避免覆盖空洞。
1)当前基站基于技术方案一获取的第一信息进行预测,预测输出第一预测信息,并发送给邻站;主要包括以下信息的一项或多项:
预测修改的覆盖配置,可包括覆盖配置的具体参数,如:实际波束宽度、影响的小区等;
预测覆盖配置修改的时间,考虑到当前基站发送第一预测信息到基站2需要一定的时间,为保证覆盖配置修改时间一致,此时间信息可用UTC时间表示;
修改覆盖配置的原因,如:是即将出现覆盖问题,还是小区边缘容量问题。
2)邻站接收第一预测信息,并根据其中预测修改的覆盖配置,推断出邻站自身将对应修改的覆盖配置;
3)基于交互的第一预测信息,覆盖配置修改可通过如下方式进行:
3.1)若第一预测信息中携带预测覆盖配置修改时间,则需修改覆盖配置的基站依据此时间进行修改;
3.2)基站还可以依据第一预测信息,判断其自身的覆盖范围需要扩大还是缩小;对于覆盖范围扩大的操作优先执行,避免覆盖配置修改过程中出现短时覆盖空洞;
4)根据3.2)中所述的覆盖配置修改方法,邻站接收到第一预测信息后,需在对应的响应消息中携带是否优先修改覆盖配置信息;并在覆盖配置修改完成后,通知其邻站进行覆盖配置的修改;该内容可以结合图8进行理解,图8为本公开实施例基站节点1和基站节点2的交互示意图。
标识1表示node2的覆盖配置是否优先修改,使用枚举值或布尔值表示;
标识2指示node2的覆盖配置已完成修改。
在实际应用中,作为一种示例,获取第一预测信息的过程中,即:AI模型训练/推断过程中,需考虑基站1/2的UE及其流量分布情况,避免出现覆盖配置修改后,局部(单个基站)性能下降(出现过载等情况),综合考虑多个基站的性能。
3.所述2中的覆盖配置修改前,基站记录/获取/存储覆盖配置修改前的UE性能信息,并标记该性能信息所处的覆盖配置;在覆盖配置修改完成后再次进行UE性能信息收集,进行覆盖配置修改前后性能对比,判断是否有性能恶化;更进一步地,基站可指定记录特定UE的性能信息;对于从UE获取的测量报告等信息,基站设置上报时间阈值,待达到上报时间阈值后,或UE上报完成测量报告后,当前基站修改CCO配置;对于出现性能恶化的情况,重复上述覆盖配置修改过程,修改覆盖配置信息进行优化。
1)在基站覆盖配置修改前,基站记录第一性能信息,包括:自身的性能及UE性能信息(吞吐量、时延、丢包率等),并标记该性能信息所处的覆盖配置,以便于后续对比;
2)其中,获取1)中的UE性能信息可通过基站向UE发送请求消息,请求UE上报现有测量报告,并设置上报时间阈值,待达到上报时间阈值后,或UE上报完成测量报告后,当前基站修改CCO配置,并通知其邻站;其中,上报时间阈值可参考预测的修改CCO配置时间来进行设置;
3)针对2)中的UE性能信息的获取,基站可指定记录特定UE在覆盖配置变化前后的性能变化,并通知邻站覆盖配置修改完成后反馈UE性能信息,其中,特定UE包括但不限于:
覆盖配置修改前后,变更覆盖波束/接入基站的UE;
特定类型的UE;
特定行业的UE。
4)覆盖配置修改完成后,基站记录第二性能信息,包括:自身的性能及UE性能信息,标记该性能信息所处的覆盖配置,并与之前记录的性能信息进行对比;
若第二性能信息相比于第一性能信息出现明显恶化,则重复上述覆盖配置修改付出;
5)若基站指定特定UE收集性能信息,则基站需对比覆盖配置修改前后的UE变化,并发送新增UE的性能信息给邻站;图9为本公开实施例基站指定特定UE收集性能信息的示意图,如图9所示,基站2在覆盖配置修改后,新增接入UE2、UE3,则基站2需发送UE2、UE3的性能信息给基站1;
6)所述5)中UE性能信息可通过Data Collection Reporting过程反馈给邻站。
在实际应用中,作为一种示例,基站接收到UE性能反馈数据后,可用于如下方面:
可用于后续的AI/ML模型训练/推断的输入数据,或用于AI/ML模型更新;
若第二性能信息相比于第一性能信息出现明显恶化,基站可通过为此类UE分配更多的资源,或者重新再次调整覆盖配置来进行UE性能的优化增强;。
本公开提出一种AI/ML辅助的覆盖与容量优化方法,通过收集邻站覆盖与容量相关数据,基站可以此为输入数据作为AI/ML模型的输入,并推断出预测的覆盖配置修改和修改时间等,基站间交互预测信息可在覆盖配置修改前同步覆盖配置修改时间和需要修改到的覆盖配置,避免在修改过程中出现覆盖空洞等问题,导致短时间内大量UE的业务中断/性能下降。基站还可指定收集特定UE在覆盖配置修改前后的性能信息进行对比,及时了解覆盖配置修改对用户的影响,并做出后续决策。
