Abstract
The present invention relates to methods and arrangements for handling UE capability information a mobile telecommunications network wherein an eNodeB (100) receives (60) information regarding the UE capability information from the UE (120) and stores (70) the information. The eNodeB (100) sends (80) the UE capability information to the EPC, i.e. the MME (130). The MME (130) receives and stores (90) the UE capability information. When the UE (120) transits from idle to active state, does an initial attach or when a part of the UE capabilities have changed, it sends (10) a message Ma to the eNodeB (100) regarding the update. The eNodeB (100) receives the message and sends (20) it to the MME (130). The MME (130) sends (30) a response associated with the previously stored UE capability information to the eNodeB (100). The eNodeB (100) decides (40) if the UE capabilities stored in the MME (130) is up-to-date based on the message sent from the UE (120) and the received response from the MME (130). If the UE (120) holds updated UE capabilities the eNodeB (100) could request (50) updated UE capability information from the UE (120).
