METHOD AND APPARATUS FOR SAVING ENERGY IN DEVICES OF A SERVICE PROVIDER

摘要

Disclosed are a method and an apparatus for saving energy in devices of a service provider (DA) who provides a service to several clients (DNx) in an at least partly sequential order by means of said devices. According to the inventive method, an appointment of a client (DNx) is registered in a queue (WS) of the service provider (DA), and a client (DNx) address is assigned to said appointment in a telecommunication network. Additionally, an expected travel time of the client (DNx) is assigned to said appointment. A message concerning the appointment is subsequently sent to the client's (DNx) address, the time of sending being chosen such that the time of the appointment and the expected travel time are taken into account, whereby it is ensured that the client (DNx) is actually ready to use the service at the agreed time.
