METHOD FOR INTERNET PROTOCOL-BASED SLEEP MODE CONTROL USING SYNCHRONIZATION INFORMATION

摘要

A method for Internet Protocol based sleep mode control using synchronization information includes setting some of the IP-based internal hosts of a sleep mode control network to a sleep mode, providing, by a base station, a synchronization signal with respect to the overall network, thereby transferring the synchronization information of a PHY/MAC layer based on a response thereto to an internal router, and updating, by the internal router having received the synchronization information of the network layer from the base station, the state of the corresponding hosts to a sleep mode, and then transmitting, by the internal router, information about the internal hosts in a sleep mode to the external hosts of a history information list because the internal router stores the history information of the external hosts that have communicated with the internal hosts in a sleep mode in the form of a list.

1. A method for Internet Protocol (IP)-based sleep mode control using synchronization information, the method being performed by IP-based hosts in a network including a sleep mode control network including the internal hosts and an internal router responsible for communication of the internal hosts, and also including an external router connected to the internal router responsible for communication of the sleep mode control network, IP-based external hosts connected via the external router, and a base station configured to provide a synchronization signal, the method comprising:
setting some of the IP-based internal hosts of the sleep mode control network to a sleep mode; providing, by the base station, a synchronization signal with respect to the overall network, thereby transferring synchronization information of a PHY/MAC layer based on a response thereto to the internal router; and updating, by the internal router having received the synchronization information of the network layer from the base station, a state of the corresponding hosts to a sleep mode, and then transmitting, by the internal router, information about the internal hosts in a sleep mode to the external hosts of a history information list because the internal router stores history information of the external hosts that have communicated with the internal hosts in a sleep mode in a list form.
