METHOD AND APPARATUS FOR HANDLING CLOSED SUBSCRIBER GROUPS IN RELAY-ENHANCED SYSTEM

摘要

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.
