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.
Claims25
An apparatus comprising a memory and a processor configured to cause a user equipment (UE) to:
- receive an Access Network Discovery and Selection Function (ANDSF) management object (MO) from an ANDSF server via a base station, 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
- 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 Radio Access Network (RAN) parameter which is supported by the E-UTRAN/UTRAN, wherein the RAN parameter is to comprise a WLAN threshold, and wherein routing of the traffic flow is through comparing a measured WLAN result with the WLAN threshold in the ANDSF MO.
An apparatus comprising a memory and a processor configured to cause an Access Network Discovery and Selection Function (ANDSF) server in a wireless network to:
- generate an ANDSF management object (MO), 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
- (EUTRAN)/UTRAN access and a Wireless Local Area Network (WLAN) access, wherein the ANDSF MO is to comprise a Radio Access Network (RAN) parameter which is supported by the E-UTRAN/UTRAN, wherein the RAN parameter is to comprise a WLAN threshold configured for routing a traffic flow through comparison of a measured WLAN result with the WLAN threshold;
- and
- transmit the ADNSF MO to a User Equipment (UE) via a base station.
A product comprising a non-transitory computer readable storage medium encoded with executable instructions, which when executed by at least one processor, cause a user equipment (UE) to:
- receive an Access Network Discovery and Selection Function (ANDSF) management object (MO) from an ANDSF server via a base station, 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
- 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 Radio Access Network (RAN) parameter which is supported by the E-UTRAN/UTRAN, wherein the RAN parameter is to comprise a WLAN threshold, and wherein routing of the traffic flow is through comparing a measured WLAN result with the WLAN threshold in the ANDSF MO.
