A schedule for a desired call, obtained, for example as an SMS message sent from a user's mobile station, enables a server to automatically initiate set-up of a voice call for the user's mobile station at a scheduled time selected by the user and indicated in the message. The user can specify time and a telephone number for the call, in advance, in the call scheduling request message. However, at the time of the call, the user does not need to read a reminder or dial the call. The call scheduling and automatic set-up services described by way of examples herein may be very useful, for example, for attending important conference calls. This may also be very useful for setting a reminder to call a special person to wish him/her well on his/her birthday/anniversary etc.
