Apparatus and methods are provided for LWA PDU routing. In one novel aspect, LTE PDU packets are routed through a WLAN AP to a UE by encapsulation of the data packets. An adaption layer encapsulate the whole packet as an Ethernet frame by appending the Ethernet MAC header to the payload. In other embodiments, the adaption layer encapsulates LTE PDU as GRE packet, configures VLAN for WLAN AP. In another novel aspect, the LTE PDU is identified by at least one of methods comprising the EtherType value, the source address, the GRE header, and the GTP header. In another embodiment, the default path is always used for LWA routing. In yet another novel aspect, the LTE PDU is forwarded by the MAC address, by the GRE tunnel configuration, or by the GTP tunnel configuration. |
