INTERNET PROTOCOL-BASED SLEEP MODE CONTROL METHOD

摘要

A method for Internet Protocol (IP)-based sleep mode control is disclosed. The method includes, when a request for a sleep mode is made from any one of internal hosts, transmitting a sleep mode request message to an internal router, updating the state of the corresponding host to a sleep mode, transmitting a sleep mode ACK message to the internal host requiring a sleep mode, switching to a sleep mode, and transmitting 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 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 in a network including a sleep mode control network including one or more 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 the communication of the sleep mode control network, and IP-based external hosts connected via the external router, the method comprising:
when a request for a sleep mode is made from any one of the internal hosts: transmitting, by one of the internal hosts requiring a sleep mode, a sleep mode request message to the internal router; updating, by the internal router having received the sleep mode request message from the internal host requiring a sleep mode, a state of the corresponding host to a sleep mode; transmitting, by the internal router, a sleep mode ACK message to the internal host requiring a sleep mode; switching, by the internal host having received the sleep mode ACK message from the internal router, to a sleep mode; and transmitting, by the internal router, information about the internal hosts in a sleep mode to external hosts of a history information list because the internal router stores history information of the external hosts that communicated with the internal hosts in a sleep mode in a list form.
