<p>One major problem solved by the invention is the challenge of managing client replies, when a client has been given a number of questions and the client is using SMS text messages or similar technology in which a reply does not automatically include an explicit reference to the inquiry. The invention solves this problem using dynamic dialog matrices. An inquiry always includes some kind of receiver's address or identification. In the SMS text message case that is so called B subscriber 's number. On the other hand, sender's A subscriber 's number or Calling Line Identity (CLI), or similar identification is also attached to each text message. If a mediator service that sends inquiries to a client, uses different A subscriber numbers in different inquires, it is possible to differentiate between answers based on which number the client is sending replies to. Using a dialog matrix, a mediator keeps track on inquires and answers. In the matrix, there is column for each client and a row for each A subscriber number the mediator is using. After sending an inquiry from a certain A subscriber number to a client, the status and the reply is stored in the corresponding shell of the matrix. As a result, the mediator is able to find out whether the client has replied to a certain inquiry and what the answer was.</p> |
