Abstract:
본 발명은 그룹 탐지와 그룹 간 병합방법 및 그 장치에 관한 것으로, 서로 다른 BPST를 갖는 다수의 그룹이 존재하거나 혹은 서로 같은 BPST를 갖는 다수의 그룹이 존재 할 경우 BCC 및 DCC, 또는 가드 슬롯을 이용하여 상대그룹을 탐지하고, 각 그룹 간을 하나의 공통된 BPST를 갖는 그룹으로 병합함으로써, WiMedia UWB 환경에서 노드의 이동성 지원, 끊김 없는 서비스 지원 및 실시간 트래픽의 서비스 품질(quality of service)을 보장해 줄 수 있다. 그룹, 탐지, 병합, 프레임
Abstract:
PURPOSE: A group detecting and inter-group merging method and an apparatus thereof are provided to guarantee mobility support of a node, continuous service support and QoS(Quality of Service) of a real time traffic. CONSTITUTION: The BPST(Beacon Period Start Time) of a super frame is discriminated(S801). When the BPST belongs to a different group and BPST detection of a counterpart group is possible, a beacon interval of the counterpart group is detected in a signaling slot(S803,S805,S807). If the BPST detection of the counterpart group is impossible, the counterpart group is detected using CC(collision count)(S823). If the beacon interval is detected, a beacon slot is reset/merged(S811,S813). Resource reservation is performed using BCC(beacon collision count) and DCC(data collision count) according to a detection result of the counterpart group(S825).
Abstract:
An access control method in a wireless LAN is provided to prevent a brute-force attack and a repeat attack of a hacker by performing periodic change and distribution of a password using an authentication number. An access control method in a wireless LAN includes the steps of: managing an assigned authentication number whenever a password is changed through an authentication number management table, and managing the authentication number used in a wireless terminal through a MAC address management table(S300); receiving subscriber information and the currently used authentication number from an accessible wireless terminal(S305); checking whether the received authentication number is the same as a predetermined authentication number for the wireless terminal corresponding to the MAC(Medium Access Control) address management table(S310); if the received authentication number is the same as the authentication number recorded in the MAC address management table, checking whether the accessible wireless terminal is an authorized subscriber based on the password recorded in the authentication number management table(S320); and if the accessible wireless terminal is the authorized subscriber, informing authentication completion to the corresponding wireless terminal(S330).
Abstract:
A method and a device for setting up an initial configuration of a wireless device using a wireless gateway in the internet environment are provided. The method for setting up the initial configuration of the wireless device using the wireless gateway in the internet environment includes a step of receiving pairing information from the wireless gateway in a smart device, where the pairing information includes information about a target device which emits a paring signal to the wireless gateway; and a step of completing the pairing with the target device. Also, the method includes a step of emitting the pairing signal to the wireless gateway in the target device; and a step of performing pairing with the smart device which received the pairing signal from the wireless gateway. Also, the method includes a step of receiving the pairing signal emitted by the target device; a step of transmitting the pairing information including information about the target device which emits the pairing signal to the smart device; a step of receiving a first device registration request message from the target device after completing the pairing between the target device and smart device; and a step of requesting registration of the target device by transmitting a second device registration request message to a management server in response to the reception of the first device registration request message.
Abstract:
본 발명은 이종장치 및 시스템에 대한 원격 유지보수 및 모니터링 서비스 프레임워크에 관한 것이다. 본 발명에 따르면, 네트워크를 통하여 이종 장치 및 시스템에 대한 공통의 유지보수 서비스 프레임워크를 제공함으로써, 유지보수 관리자가 현장을 방문하지 않고 원격으로 유지보수할 수 있어 시간과 비용이 절약된다. 또한, 본 발명은 전용선을 설치하지 않고, 로컬 네트워크에 부하를 주지 않으면서 네트워크를 통한 원격 유지보수 관리를 할 수 있게 된다. 그리고, 장치의 종류에 관계없이 이종 장치 및 시스템을 공통적으로 관리하여 유지보수 및 관리의 복잡성이 현저히 줄어들게 된다.
