  • Patent number: 9392455
    Abstract: A method and an apparatus for handling closed subscriber groups in a relay-enhanced system are provided in the invention. The method includes: retrieving setting information relating to closed subscriber groups of a donor base station and a relay node of a relay-enhanced cellular system; acquiring a whitelist defining one or more closed subscriber groups in which a terminal is a member, the terminal requesting access to the relay-enhanced cellular system via the relay node; and verifying (i.e. checking and/or validating) a membership of the terminal for both closed subscriber groups of the donor base station and the relay node based on the retrieved setting information and the acquired whitelist. With the method and apparatus of the invention, user access control via the relay node in the relay-enhanced access networks can be improved.

  • Patent number: 9338736
    Abstract: Improved systems and techniques for controlling access to network resources. A base station broadcasts extended access barring (EAB) and access class barring (ACB) information. Upon a determination by a user equipment that the user equipment requires service from the base station, the user equipment determines its EAB category and call type. The user equipment receives the EAB and ACB information broadcast by the base station and determines if it is subject to EAB based on its EAB category. If the user equipment is not subject to EAB, the user equipment determines if its call type is subject to ACB and, if the call type is subject to ACB, applies access class barring based on its call type.
