Abstract:
An operating method, a base station, and terminal of a cell of a first communication system for a handover between the first communication system and a second communication system are provided. The method includes, when a terminal initiates a handover between the first communication system and the second communication system, transmitting, by the base station, a message, requesting to measure a signal level of a downlink, to the terminal, when a signal level measured by the terminal falls below a preset threshold, requesting, by the base station, a handover to the second communication system over a core network, receiving, by the base station, a message, including radio channel parameters the that is required when the terminal accesses to the second communication system, from the second communication system, and forwarding, by the base station, the message, including the radio channel parameters of the second communication system, to the terminal.
Abstract:
An apparatus and method for determining operation of location update in a broadband wireless communication system are provided. The apparatus includes a receiver, an interpreter, and a determiner. In an idle mode, the receiver receives a paging advertisement message from a Base Station (BS). The interpreter identifies paging group identification information included in the paging advertisement message. The determiner determines one of execution and non-execution of a location update process due to a change of a paging group if the paging group identification information is different from paging group identification information included in a previously received paging advertisement message.
Abstract:
A semiconductor memory device includes a source signal generation unit configured to generate a source pulse signal having a pulse width which is determined depending on an interval between an input of an active signal and an input of a column command signal, which is inputted after an active command, and a column decoding unit configured to generate a column select signal in response to an address and the source pulse signal.
Abstract:
A semiconductor chip package with a flash memory portion and a method and system for testing the same are provided. After an internal cycling test is automatically and independently initiated on the flash memory chip, a test on other memory portions in the semiconductor chip package is performed. The semiconductor chip package includes a first flash memory portion, at least one second memory portions, and an internal cycling tester repetitively performing a batch programming operation and a batch erase operation on the first flash memory portion.
Abstract:
A multi-chip package is provided. The multi-chip package includes semiconductor chips. The multi-chip package receives selection signals for selecting two or more chips in response to the selection signals. Any number of chips may be simultaneously selected for a test and the test time can be reduced.
Abstract:
Provided are a method for transmitting and receiving broadcasting service information and a mobile station for a broadcasting service. The method for transmitting broadcasting service information at a base station, includes registering a mobile station in a first cell, wherein the first cell is a cell managed by the base station, receiving vehicle related information from the mobile station mounted on a vehicle, and broadcasting the received vehicle related information to target cells.
