Title (EN) MULTICAST SYSTEM AND METHOD USING ABBREVIATED ADDRESS BASED ON NEAR FIELD COMMUNICATION, AND DEVICE APPLIED THERETO
(FR) SYSTÈME ET PROCÉDÉ DE MULTIDIFFUSION UTILISANT UNE ADRESSE ABRÉGÉE BASÉE SUR UNE COMMUNICATION EN CHAMP PROCHE, ET DISPOSITIF APPLIQUÉ À CEUX-CI
(KO) 근거리 무선통신 기반의 단축주소를 이용하는 멀티캐스트 시스템 및 방법, 그리고 이에 적용되는 장치
Abstract: front page image
(EN)The present invention provides a multicast system and method using an abbreviated address based on near field communication, and a device applied thereto. According to the present invention, the multicast system using the abbreviated address based on the near field communication comprises a configuration for supporting the multicast at the IEEE 802.15.4 MAC (Medium Access Control) layer. Thus, when the multicast is processed through an address system of the MAC layer, the invention performs the multicast more efficiently during a power management or handling procedure by receiving data, only when a self group broadcasts the data, through simple scheduling like a beacon signal of a coordinator device is received.
(FR)La présente invention porte sur un système et un procédé de multidiffusion utilisant une adresse abrégée basée sur une communication en champ proche, et sur un dispositif appliqué à ceux-ci. Selon la présente invention, le système de multidiffusion utilisant l'adresse abrégée basée sur la communication en champ proche comprend une configuration pour prendre en charge la multidiffusion au niveau de la couche MAC (commande d'accès au support) IEEE 802.15.4. Ainsi, lorsque la multidiffusion est traitée par l'intermédiaire d'un système d'adresse de la couche MAC, l'invention réalise la multidiffusion de façon plus efficace durant une procédure de gestion de puissance par réception de données, seulement lorsqu'un groupe propre diffuse les données, par une planification simple telle que la réception d'un signal de balise d'un dispositif coordinateur.
(KO)본 발명은 근거리 무선통신 기반의 단축주소를 이용하는 멀티캐스트 시스템 및 방법, 그리고 이에 적용되는 장치를 개시한다. 본 발명에 따른 근거리 무선통신 기반의 단축주소를 이용하는 멀티캐스트 시스템은, IEEE 802.15.4 MAC(Medium Access Control) 계층에서의 멀티캐스트를 지원하기 위한 구성으로 이루어진다. 따라서, 본 발명은 MAC 계층의 주소체계를 통해 멀티캐스트를 처리할 때에는 코디네이터 장치의 비콘 신호의 수신과 같은 간단한 스케줄링을 통하여 자신의 속한 그룹의 브로드케스트가 있을 때만 수신하여 전력관리나 처리과정에서 보다 효율적으로 멀티캐스트를 수행할 수 있다.
