  • Publication number: 20200021993
    Abstract: Techniques for identity-based message integrity protection and verification between a user equipment (UE) and a wireless network entity, include use of signatures derived from identity-based keys. To protect against attacks from rogue network entities before activation of a security context with a network entity, the UE verifies integrity of messages by checking a signature using an identity-based public key PKID derived by the UE based on (i) an identity value (ID) of the network entity and (ii) a separate public key PKPKG of a private key generator (PKG) server. The network entity generates signatures for messages using an identity-based private key SKID obtained from the PKG server, which generates the identity-based private key SKID using (i) the ID value of the network entity and (ii) a private key SKPKG that is known only by the PKG server and corresponds to the public key PKPKG.

    Abstract: The present disclosure provides a method implemented by a radio network node for determining a Route Update Radius (RUR) for a Radio Base Station (RBS) and the radio network node. The method comprises determining a first radius (RUR_CCH) which defines a largest circular area centered at the RBS and excluding a first number of RBSs among the RBS's neighboring RBSs, wherein CCH occupancies for the first number of RBSs are higher than a CCH occupancy threshold. The method further comprises determining a second radius (RUR_ACH) which defines a smallest circular area centered at the RBS and covering a second number of RBSs among the RBS's neighboring RBSs, wherein ACH occupancies for the second number of RBSs are higher than an ACH occupancy threshold. The RUR is determined based on a comparison between the first radius (RUR_CCH) and the second radius (RUR_ACH).
