The network comprises a plurality of optical line terminals which communicate with a plurality of optical network units over an optical distribution network. The optical distribution network includes a plurality of optical filters controlled by a network controller. A first optical line terminal sends a request for optical communication with at least one optical network unit to the network controller. The request is sent over the optical distribution network and indicates an operating wavelength of the first optical line terminal and of the at least one optical network unit. The network controller configures at least two of the optical filters to allow a passing through of the operating wavelength or of a further operating wavelength. The optical communication between the first optical line terminal and the at least one optical network unit in the operating or in the further operating wavelength is established through the optical filters.

The invention relates to a method for routing a bi-directional end-to-end connection between an end subscriber and the domain of a service provider by means of a signalling protocol via an interposed firewall with address transformation device, wherein by means of a security and tunnel device, located in the end-to-end connection between the end subscriber and the firewall with address transformation device in the domain of the end subscriber, and a session border controller, located in the end-to-end connection in the domain of the service provider, a tunnel is set up between the security and tunnel device and the session border controller and a bi-directional data exchange takes place via the tunnel between the end subscriber and the domain of the service provider in the area between the security and tunnel device and the session border controller by means of a tunnel protocol, and also a telecommunication network and a security and tunnel device for this.

The invention concerns a method of providing session mobility to an IP based real-time session in a telecommunications network whereby the telecommunications network uses the session initiation protocol for the setup and control of the session. The session comprises a media stream between a first terminal associated to a first network access point of the telecommunications network and a second terminal associated to a second network access point of the telecommunications network. A re-invite session initiation protocol signalling message related to session mobility of said session is intercepted at a session-related session border controller of the telecommunications network. Said session border controller initiates a corresponding session hand-over of said session. In said session hand-over, the media stream of said session is redirected to a new network access point of the first terminal and/or a new terminal.

Method of providing session mobility

It is the object of the invention to make available a method of transferring user data packets from a terminal to a mainframe of an S-CDMA point-to-multipoint system, in which the data transfer is optimized. The method includes the steps of a repeated transmission of reference data packets coded with pilot codes for the duration of the connections between terminals and a mainframe, wherein the reference data packets contain previously known information, and the transmission of user data packets coded with communication codes include the user information to be transferred. In a preferred embodiment of the invention the user data packets are coded synchronously in time to the reference data packets, superimposed on these, and then modulated. Each terminal is allocated a pilot code, and at least one communication code.
