Abstract: A terminal, a method for operation of the terminal, and a method of interworking in a wireless communication system including an advanced network and a legacy network are provided. The method for operating the terminal includes monitoring a paging channel of the legacy network for a data paging message and a Circuit Switched (CS) paging message, when the terminal is in an idle state, receiving one of the CS paging message and data paging message, establishing a connection with the legacy network corresponding to the received one of the CS paging message and data paging message, wherein a CS voice connection is established with the legacy network if the CS paging message is received and a Packet Switched (PS) data connection is established with the legacy network if the data paging message is received, and performing a handover to the advanced network from the legacy network, if the PS data connection is established with the legacy network.

Abstract: A lighting device including: a light-emitting device unit including one or more light-emitting devices; a first reflector which faces the light-emitting device unit and reflects light emitted from the light-emitting device unit; and a second reflector which faces the first reflector and reflects light reflected by the first reflector.

Abstract: A bulb-type semiconductor light-emitting device lamp having wide light distribution characteristics which are similar to those of a typical incandescent bulb is provided. The semiconductor light-emitting device lamp includes: a plurality of light-emitting devices that are arranged such that light is emitted therefrom toward a central axis of the bulb-type semiconductor light-emitting device lamp. Also, the bulb-type semiconductor light-emitting device lamp includes a heat dissipation structure having a plurality of installation surfaces that surround the central axis and are separated from each other, wherein each of the plurality of light-emitting devices includes one or more light-emitting devices.

Abstract: Provided is a lighting apparatus including: a plurality of light-emitting devices; a mounting portion on which the plurality of light-emitting devices is disposed; and a light guide cover which guides light emitted from the plurality of light-emitting devices to the outside.

Abstract: The present invention relates to a method for estimating an optimized transmission bit rate in a wireless local area network (LAN) system, which is to provide an accurate data transmission bit rate according to channel status when block data are transmitted in the wireless LAN system. According to the present invention, there is provided a method for estimating an optimized transmission bit rate according to the status of a data transmission bit rate in a wireless LAN system, comprising the steps of determining whether to change a current data transmission bit rate in a wireless LAN network; and estimating an optimized transmission bit rate on the basis of results of the determination in the determining step, and reflecting the estimated transmission bit rate upon transmission of data. The method is effective in that when data blocks are transmitted in the wireless LAN system, the performance degradation of data transmission invited due to an inappropriate selection of a transmission bit rate can be reduced.

Abstract: A terminal and an advanced Base Station (BS), and methods for their operation in a wireless communication system including an advanced network that provides a data service and a legacy network that provides a Circuit Switched (CS) voice service, are provided.
