Wireless local area network router and communications method thereof

A WLAN router comprising:

• a controlling unit performing controlling to request a temporal relay terminal selected from among relay candidate terminals depending on a preset selection reference to perform a WLAN temporal relay, for the purpose of support target terminals, the support target terminals having first signal strengths lower than a first reference strength that is preset, the relay candidate terminals having second signal strengths higher than a second reference strength that is preset, the first signal strengths corresponding to signal strengths between the WLAN router and communications-enabled terminals capable of performing WLAN communications, and the second signal strengths corresponding to signal strengths between the support target terminals and the communications-enabled terminals;
• a WLAN communications unit performing the WLAN communications with the communications-enabled terminals depending on the controlling of the controlling unit to collect the first signal strengths and information required for selecting the temporary relay terminal from the communications-enabled terminals and provide the collected first signal strengths and information to the controlling unit;
• and
• a local area communications unit requesting that the temporal relay terminal perform the WLAN temporal relay of the support target terminals depending on the controlling of the controlling unit,
• wherein the controlling unit determines relay priorities as the selection reference based on the first and second signal strengths and selects a communications-enabled terminal having the highest priority as the temporary relay terminal.

A communications method of a WLAN router, comprising:

• determining support target terminals having first signal strengths lower than a first reference strength that is preset, the first signal strengths corresponding to signal strengths between the WLAN router and communications-enabled terminals capable of performing WLAN communications;
• determining that communications-enabled terminals having second signal strengths higher than a second reference strength that is preset are relay candidate terminals and selecting a temporal relay terminal among the relay candidate terminals depending on a preset selection reference, the second signal strengths corresponding to signal strengths between the support target terminals and the communications-enabled terminals;
• and
• requesting that the selected temporal relay terminal perform a WLAN temporal relay.
