1. A method for wireless communications by a user equipment (UE), comprising:
- determining, at the UE, if a serving base station of a Radio Access Network (RAN) supports interworking between wireless local area network (WLAN) and RAN;
based upon the determination, determining whether to access the serving base station before associating or exchanging transmissions with a WLAN access point (AP), wherein a policy from a core network (CN) indicates a type of traffic for which to access the serving base station before associating or exchanging transmissions with the WLAN AP for the type of traffic; and
associating or exchanging transmissions with the WLAN AP for the type of traffic after accessing the serving base station for the type of traffic, based on the policy,wherein the type of traffic comprises at least one of Internet Protocol (IP) flows, bearer, or access point name (APN) traffic.

Abstract
Methods and apparatus for offloading traffic from a cellular network to a wireless local area network (WLAN) are described. One example method generally includes receiving, from a serving base station, a request to measure one or more WLAN access points (APs), determining one or more metrics for the WLAN APs, comparing the metrics for the WLAN APs to a threshold, and reporting metrics for at least a first AP of the WLAN APs if the metrics for the first AP exceed the threshold.

9. An apparatus for wireless communications by a user equipment (UE), comprising:
-
means for determining, at the UE, if a serving base station of a Radio Access Network (RAN) supports interworking between wireless local area network (WLAN) and RAN; means for determining whether to access the serving base station before associating or exchanging transmissions with a WLAN access point (AP) based upon a result of determining if the serving base station supports the interworking between WLAN and RAN, wherein a policy from a core network (CN) indicates a type of traffic for which to access the serving base station before associating or exchanging transmissions with the WLAN AP for the type of traffic; and means for associating or exchanging transmissions with the W LAN AP for the type of traffic after accessing the serving base station for the type of traffic, based on the policy, wherein the type of traffic comprises at least one of Internet Protocol (IP) flows, bearer, or access point name (APN) traffic. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. An apparatus for wireless communications by a user equipment (UE), comprising:
-
at least one processor configured to determine, by the UE, if a serving base station of a radio access network (RAN) supports interworking between wireless local area network (WLAN) and RAN, based upon the determination, determine whether to access the serving base station before associating or exchanging transmissions with a WLAN access point (AP), wherein a policy from a core network (CN) indicates a type of traffic for which to access the serving base station before associating or exchanging transmissions with the WLAN AP for the type of traffic; and associate or exchange transmissions with the WLAN AP for the type of traffic after accessing the serving base station for the type of traffic, based on the policy, wherein the type of traffic comprises at least one of Internet Protocol (IP) flows, bearer, or access point name (APN) traffic; and a memory coupled with the at least one processor.

18. A non-transitory computer readable medium having instructions stored thereon that when executed on at least one processor causes the at least one processor to:
-
determine, by a user equipment (UE), if a serving base station of a radio access network (RAN) supports interworking between wireless local area network (WLAN) and RAN; based upon the determination, determine whether to access the serving base station before associating or exchanging transmissions with a WLAN access point (AP), wherein a policy from a core network (CN) indicates a type of traffic for which to access the serving base station before associating or exchanging transmissions with the WLAN AP for the type of traffic; and associate or exchange transmissions with the WLAN AP for the type of traffic after accessing the serving base station for the type of traffic, based on the policy, wherein the type of traffic comprises at least one of Internet Protocol (IP) flows, bearer, or access point name (APN) traffic.
