  • Publication number: 20180091969
    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.

  • Publication number: 20180069706
    Abstract: A method (400) of generating a cryptographic checksum for a message M(x) is provided. The method is performed by a communication device, such as a sender or a receiver, and comprises calculating (405) the cryptographic checksum as a first function g of a division of a second function of M(x), f(M(x)), modulo a generator polynomial p(x) of degree n, g(f(M(x)) mod p(x)). The generator polynomial is calculated (403) as p(x)=(1?x)·P1(x), and P/(x) is a primitive polynomial of degree n?1. The primitive polynomial is selected (402), based on a first cryptographic key, from the set of primitive polynomials of degree n?1 over a Galois Field. By replacing a standard checksum with a cryptographic checksum, an efficient message authentication is provided. The proposed cryptographic checksum may be used for providing integrity assurance on the message, i.e., for detecting random and intentional message changes, with a known level of security.

  • Publication number: 20180020394
    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.
