Abstract: Provided is to technology for moving a virtual entity in a virtual network. A method of moving a virtual entity implemented in a virtual network includes providing a service to a user terminal located at a first position by using a virtual entity implemented in a first host located in a first virtual network and when a position of the user terminal is changed, moving the virtual entity to another host capable of providing the service at a close distance to the position-changed user terminal.

Abstract: Provided are a screen compression service method and a virtual network apparatus performing the method. Specifically, the screen compression service method relates to a method which compresses a remote screen of a virtual machine remotely accessed through a virtual network apparatus of a network function virtualization (NFV) infrastructure separate from a cloud infrastructure where the virtual machine runs, and transmits the compressed remote screen to a user device.

Abstract: An apparatus for allocating base station resources based on virtualization. The apparatus includes a virtual scheduling part configured to comprise virtual schedulers each of which is operated for each of mobile virtual network operators (MVNOs) and performs virtual scheduling based on characteristics of a mobile service provided by each of the MVNOs, and to request resource allocation according to a virtual scheduling result; a physical scheduling part configured to comprise a channel scheduler and a quality of service (QoS) scheduler and allocate physical resources using either the channel scheduler or the QoS scheduler according to the virtual scheduling result, in response to the request for resource allocation from the virtual scheduler; and a control agent configured to interface between the virtual scheduling part and the physical scheduling part.

Abstract: In a mobile IPTV system, a multicast coordination entity (MCE) acquires information for radio resource allocation for satisfying all terminals through a counting procedure, and determines a radio bearer by considering a share of usage anticipation subcarrier for respective identifiers of contents. A scheduling subject is variable by a characteristic of the determined radio bearer.

Abstract: An apparatus and method of searching a preamble signal in a search window for reducing a chip size of a preamble searcher in a transceiver of a base station is enclosed. By using a plurality of small window preamble searchers searching the preamble signal in a small search window, which is a division of a large search windows of a conventional preamble searcher divided by search start times, the preamble searcher of the entire search window can be implemented and the size of semiconductor chip is reduced by implementing distributing small preamble searcher in a small semiconductor chips.
