Abstract: Handling of UE capability information in a mobile telecommunications network wherein an eNodeB receives information regarding the UE capability information from the UE and stores the information. The eNodeB sends the UE capability information to the EPC, i.e., to an MME, which receives and stores the UE capability information. When the UE transits from idle to active state, does an initial attach, or when a part of the UE capabilities have changed, it sends a message to the eNodeB regarding the update. The eNodeB forwards the message to the UE, which sends a response associated with the previously stored UE capability information to the eNodeB. The eNodeB decides whether the UE capabilities stored in the NUB is up-to-date based on the message from the UE and the response from the MME. If the UE holds updated OF capabilities the eNodeB can request updated UE capability information from the UE.

Abstract: Small base station, micro, femto or pico BTS (PBS) are connected via Un interface to a donor eNB DeNB. In case of a handover from that PBS packets that had not been acknowledged by a UE need to be forwarded to the target base station. Forwarding them via Un and DeNB to the target eNB causes latency and wast radio resources on Un. Thus, the DeNB uses information about the handover to buffer packets and, after being informed by PBS, forward those packets that had not been acknowledged by the UE. This procedure, therefore, saves resources on Un interface and reduces latency. No forwarding of those packets from PBS to DeNB is required. There is provided a method for forwarding data to a wireless terminal. The method is performed by a proxy node. The method comprises receiving data on a link between a core network and a backhaul hub node. The data is addressed to a wireless terminal served by, or handed over from, a serving network node.
