    • An aspect of the exemplary embodiments of this invention is a method that includes receiving information from a plurality of spatially distributed user devices (10), where the information includes at least observations of a radio environment of each user device (10). Based on the received information, the method creates a model of time evolution of a spatio-temporal map (12E) for a plurality of spatial locations. The method further includes creating a policy based on the model of time evolution of the spatio-temporal map (12E), and transmitting the policy to the plurality of user devices (10). A further aspect of exemplary embodiments of this invention is a method that includes generating a probabilistic model based at least on observations of a radio environment of a user device (10); transmitting the probabilistic model to a network access node (12) of a wireless communication network; receiving information from the network access node (12); and operating the user device (10) at least in part based on the received information. Also described are apparatus (10, 12) and computer program products that operate in accordance with the methods.
    • 本发明的示例性实施例的一个方面是一种方法,其包括从多个空间分布的用户设备(10)接收信息,其中所述信息至少包括每个用户设备(10)的无线电环境的观测值。 基于所接收的信息,该方法创建用于多个空间位置的时空映射(12E)的时间演化模型。 该方法还包括基于时空映射(12E)的时间演化模型创建策略,以及将策略发送到多个用户设备(10)。 本发明的示例性实施例的另一方面是一种方法,其包括至少基于对用户设备(10)的无线电环境的观察来生成概率模型; 将所述概率模型发送到无线通信网络的网络接入节点(12); 从所述网络接入节点(12)接收信息; 以及基于所接收的信息至少部分地操作所述用户设备(10)。 还描述了根据该方法操作的装置(10,12)和计算机程序产品。
