Methods and apparatus to identify the accessibility of base stations in communication systems

摘要

A system and method for identifying the accessibility of a base station in a communication system. The system includes at least one Closed Subscriber Group (CSG)-Open (hybrid) base station. The base station can apply a base station identifier, such as a CSG identifier, as a cyclic redundancy check (CRC) mask to a first broadcast channel communication and can include the base station identifier in the payload of, or as a CRC mask applied to, a second broadcast channel communication. A mobile station can determine from the base station identifier in the first broadcast communication if the mobile station is a member authorized closed access to the base station. The mobile station can determine from the base station identifier in second first broadcast communication if the mobile station is a non-member authorized open access to the base station.

1. For use in a wireless communications network, a mobile station capable of communicating with a plurality of base stations, the mobile station comprising:
a receiver configured to receive a first broadcast channel communication from at least one of the plurality of base stations; and a processor configured to extract a base station identifier from a cyclic redundancy check (CRC) mask in the first broadcast channel communication, and use the extracted base station identifier to determine if the mobile station is a member authorized closed access to the at least one of the plurality of base stations.
