Abstract
A method and a home location register for starting a short message transmission in a mobile telephone network. To ensure that a short message is delivered successfully, a time supervision is started upon including an identity of a short message service centre in a subscriber-specific list. When a time preset in the time supervision expires, a short message transmission starting message is transmitted to each one of the short message service centres the identity of which is included in the list. The identity of the short message service centre is deleted from the list contained in the home location register. Each short message service centre transmits, in response to a short message transmission starting message, the short message to a gateway mobile exchange for the short message to be forwarded to the subscriber.
