具体实施方式Detailed ways
Near-RT RIC通过E2接口连接基站，可以通过E2接口获取基站上报的用户级和/或QI级和/或小区级的数据，以及通过E2接口向基站下发控制信息或策略信息，以优化RAN。QI是指服务质量(QoS，Quality of Service)标识。另外，现有E2接口以及能力开放接口，具有低时延获取无线基站和外部增强数据的潜在能力。 Near-RT RIC connects to the base station through the E2 interface, and can obtain user-level and/or QI-level and/or cell-level data reported by the base station through the E2 interface, and send control information or policy information to the base station through the E2 interface to optimize the RAN. QI refers to the Quality of Service (QoS) identifier. In addition, the existing E2 interface and capability exposure interface have the potential to obtain wireless base station and external enhanced data with low latency.
Non-RT RIC可获取从管理面和云平台上报的数据，并支持无线网络管理面的智能优化。Non-RT RIC与Near-RT RIC之间通过A1接口连接；目前仅支持Non-RT RIC通过A1接口向Near-RT RIC发送信息，例如，策略信息、辅助信息(enrichment information)，以辅助Near-RT RIC实现无线网络优化；不支持Near-RT RIC通过A1接口向Non-RT RIC发送信息。Non-RT RIC can obtain data reported from the management plane and cloud platform, and support intelligent optimization of the wireless network management plane. Non-RT RIC and Near-RT RIC are connected through the A1 interface; currently only Non-RT RIC is supported to send information to Near-RT RIC through the A1 interface, such as policy information and enrichment information, to assist Near-RT RIC in achieving wireless network optimization; Near-RT RIC is not supported to send information to Non-RT RIC through the A1 interface.
为进一步支持网络和业务协同优化，O-RAN中进一步引入了无线能力开放接口，即，Near-RT RIC可以向业务应用开放实时的无线数据分析的相关信息，例如，定位或链路质量信息、辅助业务优化信息等。To further support the coordinated optimization of networks and services, O-RAN further introduced a wireless capability exposure interface, namely, Near-RT RIC, which can open relevant information of real-time wireless data analysis to business applications, such as positioning or link quality information, auxiliary service optimization information, etc.
如图1所示，O-RAN定义了Non-RT RIC架构，包含Non-RT RIC框架(framework)和无线智能应用(rApp)。其中，rApp为运行在Non-RT RIC framework上的无线智能应用，rApp可通过R1接口消费Non-RT RIC提供的R1服务。As shown in Figure 1, O-RAN defines the Non-RT RIC architecture, which includes the Non-RT RIC framework and wireless intelligent applications (rApp). Among them, rApp is a wireless intelligent application running on the Non-RT RIC framework, and rApp can consume the R1 service provided by Non-RT RIC through the R1 interface.
相关技术中，Near-RT RIC可以获取大量的RAN侧数据，并对获取到的数据进行分析，可得到对Non-RT RIC有价值的数据，例如，RAN分析数据。但是目前O-RAN架构中，Near-RT RIC不支持向Non-RT RIC提供RAN相关信息，例如，RAN分析数据、从外部获取的RAN侧数据、用户相关信息或者环境信息；Near-RT RIC不支持Non-RT RIC中的rApp访问Near-RT RIC，也不支持将RAN相关信息提供给Non-RT RIC中的rApp，这样一来，Non-RT RIC中的rApp无法获得Near-RT RIC中的RAN相关信息。In the related technology, Near-RT RIC can obtain a large amount of RAN-side data and analyze the obtained data to obtain data valuable to Non-RT RIC, such as RAN analysis data. However, in the current O-RAN architecture, Near-RT RIC does not support providing RAN-related information to Non-RT RIC, such as RAN analysis data, RAN-side data obtained from the outside, user-related information or environmental information; Near-RT RIC does not support rApp in Non-RT RIC to access Near-RT RIC, nor does it support providing RAN-related information to rApp in Non-RT RIC. As a result, rApp in Non-RT RIC cannot obtain RAN-related information in Near-RT RIC.

The fourth request is used to request registration of the wireless data types supported by the Near-RT RIC; the fourth request carries at least the information of the Near-RT RIC and the corresponding supported wireless data types, and may also carry description information of the supported wireless data types.

也就是说，业务特征信息和无线网络状态信息为可选项。That is to say, the service feature information and the wireless network status information are optional.

For example, the wireless data corresponding to the first data type, the second data type, and the third data type respectively provide this information to the Non-RT RIC, which helps the Non-RT RIC to further enhance the comprehensive perception of the real-time status of the user or wireless network and the service of the Non-RT RIC. At the same time, the wireless data corresponding to the first data type, the second data type, and the third data type respectively are obtained after being processed by the first Near-RT RIC; the first Near-RT RIC reports the processed wireless data instead of directly reporting the original data to the Non-RT RIC, which can reduce the overhead of reporting useful data and achieve more efficient data utilization and data collaboration.
另外，上述四种类型的无线数据均具有实时性特性，例如可以是百毫秒级或者秒级的无线数据，有利于Non-RT RIC实时进行网络资源优化决策以及实时的网络状态监控。In addition, the above four types of wireless data all have real-time characteristics.

在一实施例中，所述用户的位置相关描述信息包括以下至少之一：In one embodiment, the user's location-related description information includes at least one of the following:
用户的位置坐标；The user's location coordinates;
用户所属的无线网络虚拟栅格标识；The wireless network virtual grid identifier to which the user belongs;
用户的波达角(AOA，Angle Of Arrival)；The user's Angle of Arrival (AOA);
用户的波达方向(DOA，Direction Of Arrival)。The user's direction of arrival (DOA).
这里，第一Near-RT RIC对用户的接入小区的RSRP及同频邻区的RSRP，进行聚类得到无线网络虚拟栅格标识；或第一Near-RT RIC将RSRP的区间划分为不同区间，将不同的区间记为不同的无线网络虚拟栅格标识。Here, the first Near-RT RIC clusters the RSRP of the user's access cell and the RSRP of the same-frequency neighboring cell to obtain a wireless network virtual grid identifier; or the first Near-RT RIC divides the RSRP interval into different intervals, and records the different intervals as different wireless network virtual grid identifiers.
下面以统计一个波束下的用户数为例进行说明。The following takes counting the number of users under a beam as an example for explanation.
在存在N个波束的情况下，Near-RT RIC可以统计每个最小时间粒度(例如1小时)在每个波束下的用户数。When there are N beams, Near-RT RIC can count the number of users under each beam at each minimum time granularity (e.g., 1 hour).
Near-RT RIC基于用户测量的水平AOA和/或垂直AOA，确定用户的空间范围，将用户测量的水平AOA和/或垂直AOA划分为多个物理空间区域，分别确定在不同的物理空间区域内的用户数。Near-RT RIC determines the spatial range of the user based on the horizontal AOA and/or vertical AOA measured by the user, divides the horizontal AOA and/or vertical AOA measured by the user into multiple physical space areas, and determines the number of users in different physical space areas.
为得到用户数在时间和物理空间上的分布情况，还可将时间周期长度T划分为多个时间段，并确定每个时间段内的用户数在物理空间上的分布情况。比如，T为24小时，每个时间段为1个小时，第一Near-RT RIC还可以确定24小时内每个小时在AOA区域内的用户数。In order to obtain the distribution of the number of users in time and physical space, the time period length T can also be divided into multiple time periods, and the distribution of the number of users in each time period in physical space can be determined. For example, T is 24 hours, each time period is 1 hour, and the first Near-RT RIC can also determine the number of users in the AOA area every hour within 24 hours.
第一Near-RT RIC还可以基于统计的用户数，利用ML算法预测出在时间和/或空间上分布的用户数。First, Near-RT RIC can also use ML algorithms to predict the number of users distributed in time and/or space based on the statistical number of users.
