Power saving method for mobile terminal in wireless local area network

A power saving method for a wireless communication system comprising a plurality of stationary stations providing at least one mobile station in each stationary station cell with an access service, a mobile station transiting between an active mode and an idle mode, the method comprises the steps of:

• grouping the plurality of stationary stations into at least one paging group with a paging group boundary;
• determining if the mobile station is in the idle mode or the active mode;
• if the mobile station is in the idle mode, performing a handoff only when the mobile station moves across the paging group boundary, the handoff being a media access control level handoff;
• and
• performing handoff operations related to an activation of an internet protocol layer after a successful completion of paging,
• wherein the idle handoff comprises a home access point of the mobile station transmitting, to a most recently associated access point of the mobile station, a page-notify message that initiates an access point receiving the page-notify message to page the mobile station, and the most recently associated access point transmitting the page-notify message to at least one access point in a paging group of the most recently associated access point.

• determining if the mobile station is in the idle mode or the active mode;
• if the mobile station is in the idle mode, performing a handoff when the mobile station moves across the paging group boundary, not across a boundary of the stationary station cell, the handoff being a media access control level handoff;
• and
• performing handoff operations related to an activation of an internet protocol layer after a successful completion of paging,
• wherein the idle handoff comprises a home access point of the mobile station transmitting, to a most recently associated access point of the mobile station, a page-notify message that initiates an access point receiving the page-notify message to page the mobile station, and the most recently associated access point transmitting the page-notify message to at least one access point in a paging group of the most recently associated access point wherein the idle handoff comprises a most recently associated access point of the mobile station requesting, to a home access point of the mobile station, a media access control address of the mobile station, receiving, from the home access point, the media access control address, and validating the mobile station based on the media control address.
