Abstract: A method for connecting a network element to a telecommunication system comprising at least one network element, one network management system and one telecommunication network for transmitting data between the network element and the network management system. The method comprises creating, in the network management system, a registration service for registering, in the network management system, services comprised in the network elements; storing, in connection with the network element, an identifier of the registration service by means of which a data transmission connection is established from the network element to the registration service. From the network element, a registration message is transmitted to the registration service whereby the network element services are registered in the network management system wherefrom a registration message is transmitted to the network element. The network management services of the network management system are registered in the network element.
