Abstract:
이동 단말의 현재 접속 네트워크에 대한 무선 접속 인터페이스만 활성화한 상태에서 타 무선 네트워크의 상태를 측정하여 핸드오버를 수행하기 위한 장치 및 방법이 제공된다. 핸드오버 제어자는, 단일 라디오 핸드오버를 수행하는 이동 단말 및 무선 네트워크별 접속 정보를 관리하는 정보 서버와 통신을 수행한다. 핸드오버 제어자는 이동 단말의 현재 위치에서 접속 가능한 네트워크에 접속하는데 이용되는 멀티 RAT 액세스 정보를 정보 서버로부터 획득한다. 핸드오버 제어자는 멀티 RAT 액세스 정보를 이용하여 측정된 네트워크 품질 측정 결과를 이동 단말로부터 획득하고, 네트워크 품질 측정 결과를 이용하여 이동 단말의 목적 네트워크를 결정한다.
Abstract:
According to an embodiment of the present invention, a method for receiving contents in a node of an overlay network is provided. A method for receiving contents receives contents from a node which transmitted a response for a contents inquiry message by flooding the contents inquiry message to an overlay network according to the minimum spanning tree when the node which received contents identification information from a user equipment does not have the contents. [Reference numerals] (201) Smart node 1;(202) Smart node n_1;(203) Smart node n_2;(AA) User equipment;(BB,EE,GG) Yes;(CC,DD,FF) No;(S200) Contents identification information;(S201,S205) Possessing the current contents?;(S202,S209) Serving smart node;(S203,S211) Providing contents;(S204) Flooding the contents inquiry message;(S206) Ignoring the contents inquiry message;(S207) Contents response message;(S208) Requesting contents transmission;(S210) Transmitting the contents

Abstract:
PURPOSE: A communication device for a car using an IPv6 network is provided to set an IPv6 connection with an electronic control device of a specific car. CONSTITUTION: An ECU(Electronic Control Unit)(110) controls the various automotive electric parts of the vehicles. A vehicle gateway(130) supports an inner communication and an external communication of the car. A terminal(170) of a service provider sends a packet to the electronic control device through a network(150).
Abstract:
PURPOSE: An apparatus and method for controlling a handover based on centralized control between a communication network and a broadcast network are provided to request a handover from a user terminal group which is watching broadcasting contents. CONSTITUTION: If the handover of a user terminal group is determined, a target network selecting unit(220) selects a target transmission network which is supposed to transmit broadcasting contents. A transmission unit(240) transmits a message requesting the transmission preparation for the broadcasting contents to the target transmission network. A transmission and reception unit transmits a handover request message to the user terminal group which requests the handover from the target transmission network.
Abstract:
PURPOSE: A resource allocation apparatus and a method thereof in a wireless communication system for improving the transmission efficiency of data are provided to improve data throughput by efficiently using resources in a wireless LAN. CONSTITUTION: A confirming unit(110) receives channel information and base station information from a system. The confirming unit confirms the number of available channels in the system. The confirming unit confirms the number of base stations from the base station information and the bandwidth of the channels where the base stations request allocation. The confirming unit confirms the number of base stations from the base station information and the bandwidths. An allocating unit allocates one or more channels to one base station. A generating unit transmits allocation information corresponding to the channel allocation to the base stations.
