Abstract: A method for automated selection of an access interface and a source address for communication between a communication device and a network node in a communication system, comprising: executing a first selection routine for considering at least one first policy on access interface allocation; and executing a second selection routine for considering at least one second policy on source address allocation; wherein at least one first output of the first selection routine is inputted into the second selection routine or at least one second output of the second selection routine is inputted into the first selection routine.

Abstract: A system, network entities and computer programs to provide a dynamic configuration data storage system for both a standard DHCPv4 and DHCPv6 framework. Together with standard DHCPv4 and DHCPv6 protocol functionalities, the invention provides auto-configuration of configuration parameters from network servers to hosts, e.g. to mobile terminals.

Abstract: A method for handling connections of a first node located in a first network having a private address space is described. The method comprises receiving a service query for requesting a service concerning the first node from a second node, the service query comprising a global identifier of the first node, obtaining a local identifier of the first node for identifying the first node in the first network, sending the local identifier of the first node to a network element providing a connection to the first node, receiving a public identifier of the network element, and sending the public identifier of the network element to the second node. In this way, global reachability of nodes also in private networks can be achieved.

Abstract: The invention relates to a method wherein a transport layer association is established. Thereafter, a handover condition is detected in the first mobile node, which obtains a second address. The second address is updated to a first name server node. A query message is sent to a second name server node for an address of the second mobile node. The second address is indicated to the second mobile node. The first mobile node waits for a response from the second name server node or the second mobile node. Upon receiving a new address for the second mobile node from the second name server node, the first mobile node repeats the indication of the second address of the first mobile node to the second mobile node using the new address as a destination address for the second mobile node.

Abstract: The present invention concerns a method of network layer load balancing for a server farm (group of servers located on the same link) that provide identical, transaction and UDP based services, e.g. DNS service. Load balancing functionality is based on the use of the IPv6 anycast addressing for the service queries and specific Neighbour Advertisement messaging.

Abstract: The invention relates to a method for the performing of handover in a communication system. In the method a transport connection establishment request is sent from a first network node to a second network node. A node name is obtained for the second network node. A handover condition is detected by the first network node. A new address is obtained for the first network node. The new address for the first network node is updated to a name service node. A transport connection migration request is sent from the first node to the second network node. The transport connection migration request comprises a token, which identifies the connection.
