A method of managing access areas in a communication system is disclosed. In the method information regarding a detected access area is received from at least one mobile device, the detected access area being an access area that is not included in a set of available access areas. Potential of the detected access area is then predicted based on the information received from the at least one mobile device. A decision is then made, based on the predicted potential, if the detected access area can be included into the set of available access areas.
