1. A user equipment (UE), comprising:
- a transceiver to receive an Access Network Discovery and Selection Function (ANDSF) management object (MO) from an ANDSF server via an evolved NodeB (eNB), wherein the ANDSF MO is to comprise an ANDSF rule and a provisioned offload preference indicator (OPI) which is operator specific and is to indicate a preference between an Evolved Universal Terrestrial Radio Access Network (E-UTRAN)/UTRAN access and a Wireless Local Area Network (WLAN) access; and
an offloading processor to select between using the ANDSF rule and a Radio Access Network (RAN) rule, and to route a traffic flow between the E-UTRAN/UTRAN and the WLAN, at least in part based on the ANDSF rule and the OPI, wherein the ANDSF MO is to comprise a WLAN threshold, and the offloading processor is to route the traffic flow through comparing a measured WLAN result with the WLAN threshold.

Abstract
Some demonstrative embodiments include devices, systems and methods of Access Network Discovery and Selection Function (ANDSF) for traffic offloading. For example, an ANDSF Management Object (MO) may include one or more ANDSF policies, at least one ANDSF policy including ANDSF selection criteria to offload traffic between a cellular network and a Wireless Local Area Network (WLAN); and a preference indicator to indicate a preference between the ANDSF selection criteria and Radio Access Network (RAN) selection criteria from the cellular network.

8. An Access Network Discovery and Selection Function (ANDSF) server for use in a wireless network, comprising:
-
an ANDSF processor to generate an ANDSF management object (MO), wherein the ANDSF MO is to comprise an ANDSF rule and a provisioned offload preference indicator (OPI) which is operator specific and is to indicate a preference, which is to be used by a User Equipment (UE) to determine on routing traffic, between an Evolved Universal Terrestrial Radio Access Network (E-UTRAN)/UTRAN access and a Wireless Local Area Network (WLAN) access, wherein the ANDSF MO is to comprise a WLAN threshold to be used by the UE to route a traffic flow through comparing a measured WLAN result with the WLAN threshold; and a transceiver to transmit the ANDSF MO to the UE via an evolved NodeB (eNB). - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A non-transitory computer readable storage medium encoded with computer executable instructions, which when executed, cause a user equipment (UE) to:
-
receive an Access Network Discovery and Selection Function (ANDSF) management object (MO) from an ANDSF server via an evolved NodeB (eNB), wherein the ANDSF MO is to comprise an ANDSF rule and a pre-provisioned offload preference indicator (OPI) which is operator specific and is to indicate a preference between an Evolved Universal Terrestrial Radio Access Network (E-UTRAN)/UTRAN access and a Wireless Local Area Network (WLAN) access; and select between using the ANDSF rule and a Radio Access Network (RAN) rule, and route a traffic flow between the E-UTRAN/UTRAN and the WLAN, at least in part based on the ANDSF rule and the OPI, wherein the ANDSF MO is to comprise a WLAN threshold, the instructions, when executed, cause the UE to route the traffic flow through comparing a measured WLAN result with the WLAN threshold. - View Dependent Claims (16, 17, 18, 19, 20, 21)

22. A non-transitory computer readable storage medium encoded with computer executable instructions, which when executed, cause an Access Network Discovery and Selection Function (ANDSF) server to:
-
generate an ANDSF management object (MO), wherein the ANDSF MO is to comprise an ANDSF rule and a pre-provisioned offload preference indicator (OPI) which is operator specific and is to indicate a preference, which is to be used by a User Equipment (UE) to determine on routing traffic, between an Evolved Universal Terrestrial Radio Access Network (E-UTRAN)/UTRAN access and a Wireless Local Area Network (WLAN) access, wherein the ANDSF MO is to comprise a WLAN threshold to be used by the UE to route a traffic flow through comparing a measured WLAN result with the WLAN threshold; and transmit the ANDSF MO to the UE via an evolved NodeB (eNB). - View Dependent Claims (23, 24, 25, 26, 27, 28)
