Bandwidth management, aggregation and internet protocol flow mobility across multiple-access technologies
First Claim
1. A method implemented in a local gateway (LGW) communicatively coupled with a gateway of a mobile core network via a reference point over which the LGW and the gateway use tunneling to exchange internet protocol (“
- IP”
) traffic, the method comprising;
establishing a single packet data network (“
PDN”
) connection with a wireless transmit/receive unit (WTRU) via a plurality of access systems, wherein the single PDN connection terminates at the LGW;
selecting, from the plurality of access systems, first and second access systems over which to transport respective flows of the IP traffic to, from or to and from the WTRU;
sending, to the WTRU, at least one request to associate the first and second flows with the selected first and second access systems;
transporting the first flow, to, from or to and from the WTRU, via a first interface in a general packet radio service (GPRS) Tunneling Protocol (GTP) tunnel;
transporting the second flow, to, from or to and from the WTRU, via a second interface using IP connectivity;
performing protocol conversion to at least the second flow to facilitate exchange of one or more packets of the second flow to, from or to and from the gateway; and
transporting, to, from or to and from the gateway, at least one of the converted one or more packets.

Abstract
Systems, apparatuses and methods for bandwidth management, aggregation and internet protocol (“IP”) flow mobility (“IFOM”) across multiple-access technologies are provided. Included is a method that includes selecting, from a packet data network (“PDN”) connection formed through a plurality of access systems communicatively coupled with a wireless transmit and/or receive unit (“WTRU”), an access system over which to transport a flow of internet protocol (“IP”) traffic to and/or from the WTRU. The method may also include sending, to the WTRU, a request to associate the flow of IP traffic with the selected access system.

17. A local gateway (LGW) comprising a transmitter, a receiver and a processor, wherein:
-
the transmitter and receiver are configured to; communicatively couple with a gateway of a mobile core network via a reference point over which the LGW and the gateway use tunneling to exchange internet protocol (“
IP”
) traffic; andestablish a single packet data network (“
