OPPORTUNISTIC CARRIER AGGREGATION FOR DYNAMIC FLOW SWITCHING BETWEEN RADIO ACCESS TECHNOLOGIES
First Claim
1. An opportunistic cross radio access technology (RAT) bandwidth allocation system comprising:
- a wireless wide area network (WWAN) radio configured to be used as a primary cell (PCell) to communicate with a dual mode mobile wireless device on a licensed band; and
a wireless local area network (WLAN) radio integrated with the WWAN radio to form a dual mode eNB and configured to be used as a secondary cell (SCell) to provide additional wireless connectivity to the dual mode mobile wireless device in an unlicensed band that is controlled by the PCell;
wherein the PCell provides network access and mobility control for the dual mode mobile wireless device and also supports an opportunistic cross carrier bandwidth allocation through a multi-Radio Access Technology (RAT) aggregation and coordination (MRAT AC) module in the downlink and uplink of the SCell in the unlicensed band.

Abstract
Systems and methods for opportunistic cross radio access technology (RAT) bandwidth allocation are disclosed. The system comprises wireless wide area network (WWAN) radio configured to be used as a primary cell (PCell) to communicate with a dual mode mobile wireless device on a licensed band and a wireless local area network (WLAN) radio integrated with the WWAN radio and configured to be used as a secondary cell (SCell) to provide additional wireless connectivity to the dual mode mobile wireless device in an unlicensed band that is controlled by the PCell. The PCell provides network access and mobility control for the dual mode mobile wireless device and also supports an opportunistic cross carrier bandwidth allocation through a cross RAT coordination module in the downlink and uplink of the SCell in the unlicensed band.

16. A method for conducting cross radio access technology (RAT) bandwidth allocation across a wireless wide area network (WWAN) and a wireless local area network (WLAN) comprising:
-
providing a dual mode access point having a WWAN radio integrated with a WLAN access point, wherein the WWAN radio is configured to be used as a primary access cell (PCell) in a licensed band and the WLAN access point is configured to be used as a secondary access cell (SCell) in an unlicensed band; communicating discovery information for the WLAN access point via the PCell to a dual mode mobile wireless device; forming a data link between the WLAN access point and the dual mode mobile wireless device using the discovery information; receiving measurements at the dual mode access point regarding link quality indicators of the WLAN data link via the PCell; and opportunistically offloading traffic flows from the WWAN to the WLAN data link based, in part, on the received measurements to provide on-demand bandwidth allocutions to the dual mode mobile wireless device in at least one of the licensed band and the unlicensed band. - View Dependent Claims (17, 18, 19, 20)

21. A computer program product, comprising a computer usable medium having a computer readable program code embodied therein, the computer readable program code adapted to be executed to implement a method for conducting cross radio access technology (RAT) bandwidth allocation across a wireless wide area network (WWAN) and a wireless local area network (WLAN), comprising:
-
linking the WWAN and the WLAN in a dual mode access point having a primary access cell (PCell), configured to communicate via a WWAN access point in a licensed band, and a secondary access cell (SCell), configured to communicate via a WLAN access point in an unlicensed band, wherein the WWAN access point and WLAN access point are linked through a multi-Radio Access Technology (RAT) aggregation and coordination (MRAT AC) module; communicating discovery information for the WLAN access point via the PCell to a dual mode mobile wireless device; forming a data link between the WLAN access point and the dual mode mobile wireless device using the discovery information; receiving measurements at the dual mode access point regarding link quality indicators of the WLAN data link via the WWAN; and opportunistically offloading traffic flows from the WWAN to the WLAN data link using the MRAT AC module based, in part, on the received measurements to provide on-demand bandwidth allocations to the dual mode mobile wireless device. - View Dependent Claims (22, 23, 24)
