Patent ID: 8331940

Claim:
A receiver for supporting a plurality of radio access technologies (RATs), the receiver comprising: a receiving circuit configured to receive a network boundary indication from a transmitter, the network boundary indication indicating that the receiver is located in a boundary area of a first radio access network; a measuring module configured to scan a first neighboring cell that belongs to a second radio access network if a channel quality of a serving cell is below a scanning threshold and the receiving circuit has received the network boundary indication; and a handover module configured to decide a handover based on a channel quality of the first neighboring cell, wherein the first and second radio access networks correspond to different RATs, wherein the measuring module is configured to scan a second neighboring cell that belongs to the first radio access network if the channel quality of the serving cell is less than the scanning threshold, the second neighboring cell being adjacent to the serving cell in the first radio access network, wherein the handover module is configured to perform the handover to the second neighboring cell if the channel quality of the second neighboring cell is greater than the channel quality of the serving cell, and wherein the handover module is configured to perform the handover to the first neighboring cell if the channel quality of the second neighboring cell is less than the channel quality of the serving cell and the channel quality of the first neighboring cell is greater than the channel quality of the serving cell.
