A method of transferring positioning information using a set of data having a standardized set of formats for a single position entity comprises inclusion (212) of data representing at least two separate position entities or an entity having information beyond the standardized set of formats in data containers intended for points defining corners of a single polygon. The method further comprising arranging (214) of data within the set of data according to predetermined rules as an indication of an existence of such data. The set of data is transferred (230) over a communication network. In the transferred set of data, the indication of an existence of such data is detected (224) and data representing the original position is extracted (226) from the data containers intended for points defining corners of a single polygon. A communication network node performing at least a reception part or a transmission part of the method above is also presented.
