Abstract: An apparatus and a method for selecting a service network in a multi-hop relay BWA(Broadband Wireless Access) communication system are provided to increase the whole system performance by providing a relay service even for an MS(Mobile Station) which cannot recognize relay mode. If an SBC(SS Basic Capability Negotiation)-REQ(Request) message is received from an MS which is entering into a network, a BS analyzes the received message and judges whether the MS can recognize a relay mode(601-605). In case it is judged that the MS cannot recognize the relay mode, the BS transmits an SBC-RSP message to the MS and completes basic capability negotiation procedures(607). Then, the BS executes data communication after executing the remaining network entry procedures with the MS(609). At this moment, the BS transmits a MOB_SCN-RSP(Mobile Scanning Interval Allocation Response) message to the MS(611). If the MS transmits a MOB_SCN-REPORT message in response to the MOB_SCN-RSP message, the BS calculates inter-link rates, such as an MS-RS rate, an RS-BS rate, and an MS-BS rate, by using the channel state information between the MS and the BS, the channel state information between an RS and the BS, and the channel state information between the MS and the RS(613,615). Then, the BS determines whether the MS's handover to the RS is required(617). If so, the BS transmits a MOB-SCN-RSP to the MS in order to request handover to the RS(619).

Abstract: Disclosed is a method of managing a Motion Picture Expert Group-2 Transport Stream (MPEG-2 TS) in an object unit of an MPEG-4 by efficiently matching the MPEG-4 with the MPEG-2 TS, in order to broadcast an internet protocol (IP). The method manages MPEG-4 object information in an MPEG-2 TS status, by adding the object information to a program map table (PMT) in the course of converting an MPEG-4 data into an MPEG-2 TS. The method includes the steps of: a) receiving an MPEG-4 SL (Sync Layer) to be transmitted as an MPEG-2 TS; b) acquiring an object information from the MPEG-4 SL; c) aligning the acquired object information corresponding to a program map table (PMT) of the MPEG-2 TS; and d) creating an MPEG-2 TS which has the PMT corresponding to the object information.

Abstract: PURPOSE: An apparatus and a method for monitoring/correcting a wavelength path in an optical cross-connect are provided to reduce a fabrication cost by reducing the number of optical receivers and optical fiber grids for monitoring a movement path of an optical signal. CONSTITUTION: Laser diodes(110) have wavelength for optical modulation of the ith frequency as generated. Optical delay modules(120) delay the optical modulated ith frequency for a certain time. The first to the Nth wavelength demultiplexer(30) demultiplex the input 1 to input N, respectively. Optical couplers(40) couple outputs of the wavelength demultiplexers(30) with path monitoring information generated by a path monitoring information generator. Optical switches(50) switch optical signals coupled in the optical couplers(40) according to pre-set switching information. Wavelength multiplexers(60) receive signals transmitted from the optical switches(50) and multiplex them. Optical circulators(70) detect path monitoring wavelength from path monitoring information-coupled data outputted from the wavelength multiplexers(60). Optical receivers(80) convert the path monitoring wavelength detected from optical circulators(70) into an electric signal. Optical fiber grids(90) generate output 1 to output N. The ith frequency and time slot detector(150) detects the ith frequency and a tie slot from the electric signal. A comparator(140) compares previously stored routing/switching information and calculated movement path monitoring information. If a path has an error, a switching controller(130) corrects the error by controlling switching of the optical switches(50).
