Abstract: 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.

Abstract: Optical network units are connected to at least one optical routing element. The optical network units and the at least one optical routing element are controlled by an optical controller. The two endpoints are controlled by a wireless controller. A communication request between the two endpoints is created by the wireless controller. The communication request is sent from the wireless controller to the optical controller. Further the optical controller identifies the optical network units connected to the two endpoints. The optical controller checks if the optical network units belong to the same optical distribution network and configures the optical network units to transmit and receive a first wavelength spectrum and the at least one optical routing element to route the first wavelength spectrum. The optical controller requests the wireless controller to establish the communication between the two endpoints over the optical distribution network.

Abstract: 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.

Abstract: A requested communication session on a user terminal of a subscriber in a communication network via one of a plurality of access networks. The proposed method comprises the steps of checking for available network resources on all active access networks of the plurality of access networks usable by the subscriber; freeing network resources in one or a plurality of the active access networks by transferring at least one already established communication session from a first access network of the plurality of access networks to a second access network of the plurality of access networks; allocating freed network resources of the first access network for the requested communication session; and establishing the requested communication session using the allocated resources. In this way, utilization of available network resources is optimized for a given subscriber while obviating the need for complex technical decisions as to setting up or terminating communication sessions by the user.

Abstract: The invention concerns a method of managing real-time services in a packet-based telecommunications network (1) of a plurality of coequal nodes (10 to 14) and a telecommunications network (1) for executing this method. A rule base for each node (10 to 14) is defined in consideration of the capabilities of each node (10 to 14) and/or the capabilities of all other nodes (10 to 14).

Media data and/or signaling data associated with said real-time services are routed based on the determined action.

Abstract: A method for seamless handover of a multimedia stream session to a roaming terminal. In accordance with the proposed method, a first mediating network element is comprised in a communication path to the roaming terminal. Said first mediating network element first secures a session context of the multimedia stream session for to allow identification of the roaming terminal. Said first mediating network element then observes an address change of the roaming terminal on a media overlay level of the multimedia stream session and subsequently redirects the multimedia stream to the new address. Alternative mediating network elements for replacing the first mediating network element are determined on a control level of the network.

Abstract: The present invention refers to a call server for establishing a bi-directional peer-to-peer communication link between at least two user agents within a call-based environment by means of signaling messages to be exchanged between the at least two user agents. The communication link is established across a network via at least one network address translation device, which is adapted for translating private identifiers of the user agents into corresponding public identifiers usable in the network and vice versa. In order to allow build-up of the communication-link by means of signaling messages via network address translation devices, it is suggested that the call servers have an additional functionality for exploring translation information for the at least one network address translation device. This is done by exchanging explore messages between the call servers via the at least one network address translation device.
