Abstract: A method and an apparatus to perform sending towards a communication network node, information comprising a radio resource control setup request message an add slice request of at least one requested slice for fulfillment of at least one service characteristic, receiving an indication of one of an acceptance or a rejection by the network node of each of the at least one requested slice. The method and the apparatus is configured to perform receiving information comprising, a radio resource control setup request message for call admission with a network device of the communication network, wherein the information comprises an add slice request indication of at least one requested slice for fulfillment of at least one service characteristic for the network device and, based on the receiving, determining one of an acceptance or a rejection by the network node of each of the at least one requested slice.

Abstract: There are disclosed measures of address assignment for a network element being operable in a multi-level network, comprising retrieving a network prefix of said multi-level network and network prefix information including at least one of a top-level indication, a suffix length parameter and a maximum prefix length parameter, generating a first address in accordance with a topology of said multi-level network on the basis of said retrieved network prefix and network prefix information, and assigning said generated address to an egress interface of said network element.

Abstract: The present invention refers to establishing of a point-to-point connection between a mobile node and a network entity by use of an access link of the network entity, wherein the network entity is configured to manage mobility related signalling for mobile nodes attached to the access link of the network entity. According to the present invention, the mobile node is attached to the access link of the network entity. Further, a router advertisement message is transmitted from the network entity to the mobile node, wherein the router advertisement message comprises a home network prefix and a mobile node identifier. Then, a home address of the mobile node is configured from the home network prefix by the mobile node, if the node identifier represents a node identifier of the mobile node.
