The invention is related to a method and equipment used by a radio communication device (2) in a cellular network to determine whether a particular area specific service is applicable. A base station (6) transmits a first character sequence (4) which is advantageously a binary number. The radio communication device (2) selects on the basis of a second character sequence (5) stored in its memory (12) certain characters of the first character sequence (4) for examination. A logic AND or OR function (15-20) is performed for these characters indicating whether said service is applicable. By adding area specific character sequences (7) to the message sent by the base station (6) and making the recognition algorithms of the radio communication device more complex it is possible to establish a versatile service system with geographical and temporal variation. Said service can be, for example, area specific pricing.
