  • Publication number: 20110190019
    Abstract: Provided is an apparatus and a method for managing s system frame number (SFN) in a wireless communication system. A base station allocates information about the SFN to a physical downlink control channel (PDCCH) and transmits the PDCCH, and a mobile terminal reads the PDCCH at each discontinuous reception (DRX) cycle to inspect whether the mobile terminal received a paging message, and determines whether an SFN of the mobile terminal is identical to an SFN of the base station using the information about the SFN included in the PDCCH, thereby solving a difference in SFN.
