Abstract:
PURPOSE: A mobility management method of a mobile router in a mobile communication network and an apparatus therefor are provided to offer a path re-routing function to a new mobile router. CONSTITUTION: A controller(800) periodically scans the reference signals which are transmitted through an access link from an one or more adjacent mobile routers. The controller controls the procedures of forming an adjacent mobile router and a feed link using the collected scanning result. A transceiver(802) transmits and receives whole signals of the mobile router.

Abstract:
PURPOSE: A handover message transmitting power control method and apparatus in a mobile communications system is provided to control a ranging code for ranging with a target BS(Base Station) and the transmitting power of a ranging request message according to calculated maximum transmitting power, thereby increasing the successive reception probability of the target BS. CONSTITUTION: An MS(Mobile Station) performs synchronization with a handover target BS(Base Station)(314). The MS calculates the maximum transmitting power of a handover ranging message through uplink information previously obtained. The MS transmits a CDMA(Code Division Multiple Access) ranging code to the target BS at a power level less than the calculated maximum transmitting power(316). The target BS station transmits a ranging response message or a CDMA assignment information element message to the MS(318). The target BS transmits a ranging response message including information about power control to the MS(322).
Abstract:
PURPOSE: A session connection control device in a communication system and method thereof are provided to control the connection of a session and to determine the characteristic of each layer through network supplying information. CONSTITUTION: A session characteristic determination unit(211) determines the characteristic of a transport layer, a network layer, and a physical layer. A path characteristic determination unit(213) selects a transport path for the connection of a session. The session characteristic determination unit determines the characteristic of the selected transmission path. A session connection control unit(215) controls the connection of the session.
Abstract:
A user terminal and a method thereof for providing a service through handover are provided to maintain the quality of end-to-end service and to reduce the help of network in uplink layer. A service quality manager(220) determines the service quality customer satisfaction measurement of a service flow. A sequence manager(230) combines a service flow providing the same service transmitted through multi-path for handover. A handover manager(240) selects handover access network performing handover. When the handover manager provides the service through multi-path, the service flow satisfying a handover completion condition is connected.
