IN-BAND CONTROL SIGNALING FOR INTEGRATED WLAN/3GPP RAT ARCHITECTURES
First Claim
Patent Images
1. An integrated radio access technology (“
- RAT”
) system, comprising;
a wireless local area network (“
WLAN”
) component to communicate with a user equipment (“
UE”
) using unlicensed frequency spectrum; and
processing circuitry configured to;
receive information from the UE, the received information being associated with a bearer between the UE and the WLAN component, the received information being received via a Packet Data Convergence Protocol (“
PDCP”
) layer;
determine, based on the received information, one or more parameters relating to the bearer between the UE and the WLAN component; and
provide the one or more parameters to the UE, the one or more parameters causing the UE to modify a manner in which traffic is transmitted from the UE over the bearer between the UE and the WLAN component.

Abstract
An integrated WLAN/WWAN Radio Access Technology (“RAT”) architecture is described, in which signaling used to control the integration of the WLAN/WWAN architecture is performed over the Packet Data Convergence Protocol (“PDCP”) layer, and/or at other layers (e.g., a layer between the PDCP layer and the Internet Protocol (“IP”) layer). When involving the PDCP layer, non-standard PDCP packets, including variable length PDCP packets, may be used. The integrated architecture may provide a network controlled framework for performing traffic steering and radio resource management.
