Abstract

A method, system and network device routes a message to a temporarily unavailable network user, wherein a subscription to a registration state of the network user is initiated if the network user is indicated as being unavailable. Then, a notification is generated, when the registration state of the network user is changed to indicate a state when the network user is available again or when the network user is registered again, and the message is routed to the network user in response to receiving the notification. Thereby, network elements or servers generating messages can be informed about the connection state of the network user.
