Method of efficiently transmitting data during a handover in a wideband radio access network
First Claim
1. A method of transmitting data from a mobile node (MN) to a core network (CN) through at least one intermediate router (IR) in a wideband radio access network system where the MN is wirelessly connected to the CN through a first IR and a second IR neighboring the first IR is tunneled to the first IR, comprising the steps of:
- transmitting data from the MN to the first IR and the second IR; and
if at least one of the first and second IRs receives the data normally, transmitting the received data to the CN through the first IR by the at least one of the first and second IRs.

Abstract
A wideband radio access network system in which a predetermined MN is wirelessly connected to a CN through a first IR and a second IR neighboring the first IR is tunneled to the first IR, to transmit data from the MN to the CN through at least one IR. The MN transmits data to the first and second IRs, and if at least one IR receives the data normally, the at least one IR transmits the received data to the CN through the first IR.

6. A method of transmitting data from a core network (CN) to a mobile node (MN) through at least one intermediate router (IR) in a wideband radio access network system in which the MN is wirelessly connected to the CN through a first IR and a second IR neighboring the first IR is tunneled to the first IR, comprising the steps of:
-
transmitting data from the CN to the first IR;
transmitting the data from the first IR to the MN;
forwarding the data from the first IR to the second IR; and
transmitting the data from the second IR to the MN. - View Dependent Claims (7, 8, 9, 10)

11. A method of transmitting data from a core network (CN) to a mobile node (MN) through at least one intermediate router (IR) in a wideband radio access network system in which the MN is wirelessly connected to the CN through a first IR and a second IR neighboring the first IR is tunneled to the first IR, comprising the steps of:
-
measuring channel conditions of the first and second IRs from signals received from the first and second IRs by the MN;
reporting the channel conditions from the MN to the first and second IRs;
transmitting data from the CN to the first IR;
forwarding the data from the first IR to an IR in the best channel condition; and
transmitting the data from the IR in the best channel condition to the MN. - View Dependent Claims (12, 13, 14, 15)

-
measuring channel conditions of the first and second IRs from signals received from the first and second IRs by the MN; and
transmitting data including information indicating an IR in a best channel condition from the MN to the first and second IRs. - View Dependent Claims (17, 18, 19, 20)
