Abstract: The present invention relates to access node device (1) arranged for receiving and forwarding data packets in a communication network (2), the device comprising at least one processor (20) arranged to: receive data packets from an user node (3); and forward the data packets in a stateless mode over a first path to a destination gateway node (4), the first path being a default path, or forward the data packets in a stateful mode over a second path to a destination node, the second path being determined by user and/or session specific information for said user node (3). Furthermore, the invention also relates to a corresponding gateway node device, a method in an access node, a method in a gateway node, a computer program, and a computer program product thereof.

Abstract: A method in a radio resource allocator of a radio access network is disclosed. The network comprises at least one first layer and at least one second layer, the first layer is higher than the second layer; and the method in a first radio resource allocator of the first layer comprises: decides if a second radio resource allocator of the second layer in an autonomous mode or in a controlled mode for at least one portion of available radio resources; when the second radio resource allocator in the autonomous mode, allocates the at least one portion of available radio resources to the second radio resource allocator; when the second radio resource allocator in the controlled mode, allocates the at least one portion of available resources to radio resource users of the radio resource users of the second radio resource allocator and/or radio resource allocators of a third lower layer.

Abstract: The present invention relates to a method for energy saving in a cellular communication system, the cellular communication system including one or more clusters of cells. Each cluster includes one or more base stations and one or more mobile stations. The method includes exchanging, between base stations belonging to a first cluster, measurement information associated with mobile stations of the first cluster, and changing energy saving configuration for cells belonging to the first cluster based on the measurement information.

Abstract: Channel resource allocation is disclosed. Embodiments of channel resource allocation allocate channel resources to plural cells or cell sections according to a classification depending on distribution statistics.
