Abstract: Systems and methods are provided for determining precedence between Radio Access Network (RAN) rules and Access Network Discovery and Selection Function (ANDSF) rules when a mobile communication device has access to more than one set of rules for offloading data. Systems and methods for transmitting an offloadable Access Point Name (APN) to a mobile communication device when RAN rules are used. Embodiments of the present disclosure combine the advantages of signaling methods when offloading information to a mobile communication device after a RAN rule has been satisfied such that a base station is able to broadcast a signal that enables all devices camped on an serving cell to offload to the APN.

Abstract: Systems and methods are disclosed to provide offloading procedures that reduce signaling load. Specifically, embodiments of the present disclosure provide offloading techniques that enable signaling overhead caused by attachment procedures to be avoided when user equipment (UE) reconnects to a cellular network after offloading data to a Wireless Local Area Network (WLAN). According to an embodiment, at least one Public Data Network (PDN) is kept connected through the cellular network access when other PDN connections are offloaded to WLAN. According to another embodiment, a PDN connection through cellular network access is suspended, rather than detached, when data is offloaded to WLAN.

Abstract: 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.
