3GPP BEARER-BASED QOS MODEL SUPPORT ON WIFI
First Claim
1. A method implemented by a network node in a broadband access network or a wireless local area network (WLAN) to provides broadband access to a packet data network from the WLAN via a packet data network gateway, wherein the broadband access is provided for a wireless terminal in the WLAN, the method comprising:
- receiving a bearer request from the packet data network gateway that includes one or more Quality of Service (QoS) requirements, and that requests creation of a dedicated bearer;
responsive to receiving the bearer request, sending a request to an access point in the WLAN for load information indicative of a load of the access point;
receiving the requested load information from the access point;
determining, based on the load information, whether the access point would be able to meet the one or more QoS requirements if the bearer request was granted; and
if the determining indicates that the access point would be able to meet the one or more QoS requirements, creating the dedicated bearer between the wireless terminal and the packet data network gateway according to the one or more QoS requirements.

Abstract
A method is disclosed for providing broadband access to a Packet Data Network (PDN) from a WLAN. A network node receives a request for a dedicated bearer from a PDN gateway, along with one or more Quality of Service (QoS) requirements. Responsive to the bearer request, the network node sends a request to an access point in the WLAN for load information indicative of a load of the access point, and receives the requested load information. Based on the load information, the network node determines whether the access point would be able to meet the one or more QoS requirements if the bearer request was granted. If the determining indicates that the access point would be able to meet the one or more QoS requirements, the network node creates the dedicated bearer between the wireless terminal and the PDN gateway according to the one or more QoS requirements.

9. A method implemented by an access point in a wireless local area network (WLAN) that is operative to connect a wireless terminal in the WLAN to a packet data network through a broadband access network, the method comprising:
-
receiving a request from a network node in the broadband access network for load information indicative of a load of the access point; transmitting the requested load information to the network node; subsequently receiving, based on the transmitted load information, a bearer identifier (ID) and a Differentiated Services Code Point (DSCP) indicator for a dedicated bearer; receiving uplink traffic from the wireless terminal that includes the DSCP indicator and the bearer ID; and transmitting the received uplink traffic to the packet data network using the dedicated bearer. - View Dependent Claims (10)

11. A method implemented by a wireless terminal that is operative to communicate with a packet data network through a wireless local area network (WLAN) that connects to the packet data network via a broadband access network and a core network, the method comprising:
-
transmitting a request to a policy controller in the core network for a new service; based on the request for a new service, receiving a bearer request to create a dedicated bearer for the new service, the bearer request including one or more Traffic Flow Templates (TFTs) for the bearer; and thereafter, if uplink traffic from the wireless terminal matches any of the one or more TFTs, using the dedicated bearer to transmit the uplink traffic to the packet data network through the WLAN, the broadband access network, and the core network. - View Dependent Claims (12, 13)

14. A network node configured for use in a broadband access network or wireless local area network (WLAN), to provide broadband access to a packet data network from the WLAN via a packet data network gateway, wherein the broadband access is provided for a wireless terminal in the WLAN, the network node comprising one or more processing circuits configured to:
-
receive a bearer request from the packet data network gateway that includes one or more Quality of Service (QoS) requirements, and that requests creation of a dedicated bearer; responsive to receipt of the bearer request, send a request to an access point in the WLAN for load information indicative of a load of the access point; receive the requested load information from the access point; determine, based on the load information, whether the access point would be able to meet the one or more QoS requirements if the bearer request was granted; and if the determining indicates that the access point would be able to meet the one or more requirements, create the dedicated bearer between the wireless terminal and the packet data network gateway according to the one or more QoS requirements. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21)
