A method performed in a node comprised in a communication network is disclosed. The method includes obtaining a set of coordinates of a coordinate system used by the communication network, which set of coordinates specifies a geographical position held by the node. The method includes obtaining a first identifier for the node. The identifier comprises at least a part of the obtained set of coordinates, where the identifier can specify to the communication network a first geographical area in which the node is positioned. The method includes uploading data to a server in the communication network, the data being associated with the obtained identifier when uploaded to the server. The first identifier specifies to the network, such as other nodes in the communication network, a geographical area in which the node is positioned/located. The geographical area may be of any size, but includes the place where the node is positioned.
