Abstract: Embodiments of the present invention relate to a router able to cooperate with a mobile host of a home network for initializing a communication between said mobile host and a correspondent node over at least a first and a second networks, said mobile host comprising at least a first and a second network interfaces able to connect respectively to said first and second networks, said router being further able to: Attach the mobile host to said second network ; Receive a request for a communication address ; Transmit a communication address to said mobile host ;and Configure said mobile host with a predefined model indicator for enabling said mobile host to receive through its second network interface some data sent by the correspondent node towards the first network interface. Embodiments of the invention also relate to a mobile host with which the router cooperates.

Abstract: In an embodiment, there is provided a method for enhancing a network-based IP mobility management protocol to provide multihoming support, said method including providing multihoming support based on multihoming group information, said information identifying a group of interfaces of a Mobile Node MN to be managed by a Local Mobility Anchor LMA on a Mobile Access Gateway MAG demand under a same mobility session.

Abstract: A method is disclosed, by which a local mobility anchor (LMA) In a proxy mobile IP network can perform address assignment for a mobile node in cooperation with network address translation, so that the mobile node can be configured with a private HoA. In one embodiment, the LMA obtains the NAI of a mobile node (MN) that is: (i) operating as an IPv4 host and (ii) seeking entry to the network as its home network. The LMA identifies a DHCP server located in the network and serving at least one NAT, and sends it a request message in which the ClientId is set equal to the NAI of the mobile node. The LMA receives a private HoA from the DHCP server, which it forwards in a PBA message to a mobile access gateway (MAG) connected to the MN.

Abstract: A method for performing route optimization between two nodes in network based mobility management, wherein each of the two nodes is associated with an access network via attachment to an access router, the access routers having directly or indirectly assigned a Mobility Access Gateway (MAG) that signals the node's presence to a Mobility Anchor (MA) which maintains the current IP address information along with location information of the node, is characterized in that some specific control for setting up a route optimized path for data packet exchange between the two nodes is assigned to the Mobility Anchors (MA).

Abstract: A method for operating a mobile node, wherein the node (1) has such a dual functionality that it can be operated in a mobile radio network (2) working with optimized area coverage, preferably a 3GPP network, as well as in a wireless local area network (WLAN) (3), preferably a WLAN according to IEEE 802.11 standard, and wherein the node (1) can change in the context of a vertical handover from one network (2;3) to another network (3;2) is with regard to a possibly smooth handover where the loss of packets is minimized as far as possible, and where the continuity of services maximize characterized in that that two thresholds (4, 5) are defined for the WLAN signal strength received at the node (1), wherein in case of exceeding the first threshold (4) a change to the WLAN (3) and in case of falling below the second threshold (5) a change back to the mobile radio (2) network is performed.

Abstract: A method for providing information concerning broadcast contents for a user is designed and further developed in such a way that the user sets preferences regarding the broadcast contents via the network, achieving the option of a systematic selection of program contents in an infrastructure that is at the same time as simple as possible. The user is connected to a network—a mobile radio network, Internet or the like —and can receive broadcast. From the broadcast contents one or more program lists representing the broadcast contents corresponding to the set preferences are generated by using the set user-specific preferences. On the base of the program lists status lists reflecting the current states and changes of state of the broadcast contents that are handed over together with the program lists are generated by a software program executed at the user.

Abstract: A method of providing information concerning broadcast contents to a user wherein the user is connected to a network—mobile radio network, Internet or the like—and is able to receive broadcasting, is characterized in—regarding the possibility of a systematical selection of broadcast contents by the user—that the user sets preferences regarding broadcast contents via the network, and that the user-specific, set preferences are combined with the sent broadcast contents by creating status lists capturing current statuses and status changes referring to the broadcast contents as set in the preferences, and that the status lists are made available to the user by a Presence server.
