Abstract
A method of performing, and an apparatus to perform, handover in a mobile node, the method including selectively performing the handover according to neighbor information received from a predetermined access point, wherein the neighbor information comprises information regarding at least one access point neighboring the predetermined access point.
Claims19
A method of performing handover in a mobile node, the method comprising:
- receiving neighbor information, obtained by a predetermined access point from at least one access point neighboring the predetermined access point, to allow the mobile node to connect to a subnet among a plurality of subnets;
- and
- selectively performing the handover according to a change in the subnet that is connected to the mobile node based on the received neighbor information.
An apparatus to perform handover in a mobile node, comprising:
- a receiver to receive neighbor information, obtained by a predetermined access point from at least one access point neighboring the predetermined access point, to allow the mobile node to connect to a subnet among a plurality of subnets;
- and
- a handover performer to selectively perform the handover according to a change in the subnet that is connected to the mobile node, based on the neighbor information received by the receiver.
A computer readable medium having recorded thereon a computer readable program to perform a method of performing handover in a mobile node, wherein the method comprises:
- receiving neighbor information, obtained by a predetermined access point from at least one access point neighboring the predetermined access point, to allow the mobile node to connect to a subnet among a plurality of subnets;
- and
- selectively performing the handover according to a change in the subnet that is connected to the mobile node based on the received neighbor information.
A method of supporting handover in a predetermined access point to allow a mobile node to connect to a subnet among a plurality of subnets, the method comprising:
- obtaining neighbor information from at least one access point neighboring the predetermined access point;
- and
- transmitting the obtained neighbor information to the mobile node;
- wherein the mobile node selectively performs the handover according to a change in the subnet that is connected to the mobile node based on the received neighbor information.
An apparatus to support handover in a predetermined access point to allow a mobile node to connect to a subnet among a plurality of subnets, the apparatus comprising:
- a neighbor information obtainer to obtain neighbor information from at least one access point neighboring the predetermined access point;
- and
- a transmitter to transmit the neighbor information obtained by the neighbor information obtainer to the mobile node;
- wherein the mobile node selectively performs the handover according to a change in the subnet that is connected to the mobile node based on the received neighbor information.
A computer readable medium having recorded thereon a computer readable program to perform a method of supporting handover in a predetermined access point to allow a mobile node to connect to a subnet among a plurality of subnets, wherein the method comprises:
- obtaining neighbor information from at least one access point neighboring the predetermined access point;
- and
- transmitting the obtained neighbor information to the mobile node;
- wherein the mobile node selectively performs the handover according to a change in the subnet that is connected to the mobile node based on the received neighbor information.
A frame including neighbor information, obtained by a predetermined access point from at least one access point neighboring the predetermined access point, to allow a mobile node to connect to a subnet among a plurality of subnets, the frame comprising:
- a field to record an ID of an access router that provides routing service in the subnet in which the neighboring access point is located.
A method of performing handover in a mobile node, the method comprising:
- selectively performing the handover according to neighbor information received from a predetermined access point, without IP layer communication between the mobile node and an access router;
- wherein the neighbor information comprises information regarding at least one access point neighboring the predetermined access point.
