METHOD AND DEVICE FOR TRANSMITTING SCANNING START INFORMATION OF DIFFERENT RADIO ACCESS NETWORK
First Claim
1. A receiver for supporting a plurality of radio access technologies (RATs), the receiver comprising:
- a receiving circuit configured to receive a network boundary indication for indicating that the receiver is located in a boundary area of a network from a transmitter; and
a measuring module configured to scan a neighboring cell that belongs to other RAT when a channel quality of a serving cell is below a scanning threshold.

Abstract
A method and device for providing reference information for starting scanning a different radio access network to a terminal in a boundary area is provided. A receiver supporting a plurality of access systems includes a receiving circuit for receiving a scanning threshold from a transmitter, a first measuring module for measuring channel quality of a serving cell, and a second measuring module for starting scanning a neighboring cell that is a different radio access network when channel quality of the serving cell is less than the channel quality threshold. The receiver may further include a handover module for performing handover to the neighboring cell when the channel quality of the neighboring cell measured by the second measuring module is greater than that of the serving cell.

10. A method for supporting a handover of a receiver supporting a plurality of radio access technologies (RATs) in a transmitter, the method comprising:
-
transmitting a network boundary indication for indicating that the receiver is located in a boundary area of a network to the receiver; and transmitting information on other RAT to the receiver, wherein the network boundary indication and the information on the other RAT are included in an AAI-L2-XFER message that is transmitted from the transmitter to the receiver. - View Dependent Claims (11, 12)
