Abstract
A method for performing an opinion poll with a mobile communication system having a data processing block, a plurality of recipient mobile stations comprising a wireless communication block and a display, and service center having a buffer. A query message is entered to the data processing block, a predetermined answering period is defined, and the buffer is provided with the query message. This is followed by attempting to send wirelessly the query message from the buffer substantially simultaneously to the recipient mobile stations, attempting again if necessary, and storing at least temporarily the query message at the recipient mobile stations. The query messages are then presented at recipient mobile stations and their users are allowed, at a convenient moment, to enter a written answer message to the mobile station. The written answer messages are sent wirelessly to the service center, forwarded from the service center to the data processing block; and processed by the data processing block, if received by the processing block within the answering period.
