Abstract: An anti-miss alarm system, method, and a shoe supporting the anti-miss alarm is provided. The anti-miss alarm method receives a radio signal emitted from a portable article having an interface for a wireless personal area network (WPAN), extracts channel status information from the radio signal, calculates a relative distance from the portable article based on the channel status information, and outputs alarm signals in a stepwise manner according to the relative distance. A mobile terminal includes an interface of a WPAN, a control unit, and an output unit. The interface receives radio signals emitted from a portable article having a similar interface. The control unit extracts channel status information from the radio signals and estimates a relative distance from the portable article based on the channel status information. The output unit controllably outputs alarm signals in a stepwise manner according to the relative distance.

Abstract: An apparatus and method for a handover in a mobile communication system are provided. The handover apparatus includes an interface unit for setting a first path used before the handover and a second path used after the handover, for the mobile terminal undergoing the handover. A controller determines whether or not data to be transmitted to the mobile terminal is real-time data upon receipt of the data, transmits the data to the mobile terminal through the first and second paths when it is determined to be real-time data, and buffers the data and transmits the buffered data to the mobile terminal through the second path after completion of the handover when it is determined not to be real-time data. A buffer stores the buffered data until the handover is completed.
