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 MME, 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 MME is up-to-date based on the message from the UE and the response from the MME. If the UE holds updated UE capabilities the eNodeB can request updated UE capability information from the UE.
