CELLULAR-WIRELESS LOCAL AREA NETWORK (WLAN) INTERWORKING

摘要

A device for facilitating cellular-wireless local area network (WLAN) interworking may include at least one processor circuit. The processor circuit may be configured to receive a packet including a first tunnel identifier and addressed to a user equipment (UE). The processor circuit may be configured to identify a radio bearer associated with the first tunnel identifier, where the radio bearer is configured to facilitate transmission of the packet to the UE via cellular communications. The processor circuit may be configured to determine whether the radio bearer has been offloaded over a WLAN. The processor circuit may be configured to, when the radio bearer has been offloaded over the WLAN, identify a second tunnel identifier mapped to the radio bearer; encapsulate the packet based on the second tunnel identifier, where the encapsulated packet includes the second tunnel identifier; and transmit the encapsulated packet to the UE over the WLAN.

1. A device, comprising:
at least one processor circuit configured to:
receive a packet comprising a first tunnel identifier, the packet being addressed to a user equipment (UE);identify a radio bearer associated with the first tunnel identifier, the radio bearer configured to facilitate transmission of the packet to the UE via cellular communications;determine whether the radio bearer has been offloaded over at least a portion of a wireless local area network (WLAN); andwhen the radio bearer has been offloaded over the at least the portion of the WLAN:
identify a second tunnel identifier mapped to the radio bearer;encapsulate the packet based on the second tunnel identifier, wherein the encapsulated packet comprises the second tunnel identifier; andtransmit the encapsulated packet to the UE over the at least the portion of the WLAN.
