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.

Abstract: A network node (600), a wireless device (602) and methods therein, for enabling access to a radio network. System signatures are associated with corresponding system information configurations that can be used for accessing the radio network in a first area. The system signatures are reused in a second area as associated with system information configurations which are different than in the first area. The network node (600) indicates (6:3) that at least one system information configuration stored in the wireless device (602) is invalid and should not be used. The wireless device (602) then makes (6:4) the at least one invalid system information configuration unusable in the wireless device, e.g. by deleting it from the wireless device (602). Thereby, the risk of using an incorrect system information configuration based on a reused system signature can be reduced or eliminated.
