US 2013/0156007 A1 · Handover in White Space Band

Abstract

A station forms a connection with a first access point (AP): a particular station for storing first active station identification information of an active station that manages the activation of the station serviced by said first AP accesses a region serviced by a second AP, and receives from said second AP a message for containing second active station identification information of the active station that manages the activation of the station serviced by said second AP; said first active station identification information is compared with said second active station identification information; and if said first active station identification information is different from said second active station identification information, a procedure for changing the active station and a handover to said second AP are performed to a second active STA corresponding to said second active station identification information.

Dependent claims

A method for performing handover by a station (STA) in a white space band wireless communication system, the method comprising:

allowing a specific STA to access a service region of a second access point (AP), wherein the specific STA is associated with (or connected to) a first access point (AP) and stores identification information (hereinafter referred to as first enablement STA identification information) of an enablement STA managing STA enablement provided by the first AP;
receiving a message including identification information of the enablement STA (hereinafter referred to as second enablement STA identification information) provided by the second AP, from the second AP;
comparing the first enablement STA identification information with the second enablement STA identification information;
if the first enablement STA identification information is different from the second enablement STA identification information, performing not only a procedure for changing an enablement STA to an enablement STA (hereinafter referred to as second enablement STA) corresponding to the second enablement STA identification information, but also a handover to the second AP.

1 more element

A station (STA) device for performing handover in a white space band wireless communication system, comprising:

a memory for storing identification information of an enablement STA managing STA enablement provided by a first access point (AP) (hereinafter referred to as a first AP) associated with the STA device;
a transceiver, if the STA device accesses a service region of a second access point (AP), for receiving a message including identification information of the enablement STA (hereinafter referred to as second enablement STA identification information) provided by the second AP, from the second AP;
and
a processor connected to the memory and the transceiver, for comparing the first enablement STA identification information with the second enablement STA identification information when receiving the message, if the first enablement STA identification information is different from the second enablement STA identification information, and performing not only a procedure for changing an enablement STA to an enablement STA (hereinafter referred to as second enablement STA) corresponding to the second enablement STA identification information, but also a handover to the second AP.
