When a mobile network delivers a call to a called user, it also sends a command signal for commanding the called user's mobile telephone to enter a predetermined menu function related to that call. For example, if the call is an SMS message, the command signal contains a numeric sequence command code, e.g. "23", and the control unit of the mobile telephone responds by treating this code as a menu shortcut and entering its Write Message function. This anticipates that the most likely next action of the called user is to create a reply message. The called user does not have to select manually the Write Message function from the Messages function of the menu. |
