Abstract: A telecommunications network adapted to process data packets according to the client mobile internet protocol domain is extended to provide bearer capability, such that sub-sessions can be used to distinguish one portion of traffic from another. A different Quality of Service (QoS) can be assigned to each bearer. The bearers can be setup by a mobile node or a home agent in the telecommunications network.

Abstract: The present invention relates to a method and a transceiver device in a wireless communication system that enable tuning of the polarization generated by a cross-polarized transmitting antenna configuration of an eNB. This is addressed by a solution where the polarization is adjusted (320) based on a quality indicator e.g. received (310) from one or more UEs. The quality indicator indicates the quality of the communication between the eNB and the UEs, and is used to determine if the adjustment of the antenna configuration is improving the quality of the communication or not. The tuning is thus an iteration (330) of the steps of adjusting (320) the polarization and of receiving (310) the quality indicator, and when the quality indicator has reached a pre-determined value, the iteration is stopped.

Abstract: In accordance with an embodiment of the present invention, a network node is presented which is configured to associate each of a plurality of MAC addresses with an IP address on a network level. The network node is configured to, upon reception of a link level message comprising a target IP address and destined to multiple network nodes, compare the target IP address with associated MAC/IP addresses on a network level, and to selectively send the received link level message to at least one other network node on a link level based on the network level comparison. A method and a computer program product are also presented, according to embodiments of the present invention.
