System and Methods for Dual Mode Network Selection

摘要

Embodiments are provided for supporting network selection for dual mode user equipment that access both WiFi and 3GPP networks. The embodiments allow a UE to determine network selection for a WLAN using an Access Network Discovery and Selection Function (ANDSF) according to the UE's capability to support a HotSpot 2.0 (HS2.0) WiFi selection mechanism. In an embodiment, the ANDSF server provides the UE with network selection policy and discovery information indicating available wireless access networks to the UE. The information provided to the UE includes both information for HS2.0 capable UEs and information for non-HS2.0 capable UEs. The UE then selects the suitable information for network selection according to UE support or lack thereof for HS2.0. In another embodiment, the ANDSF receives capability information from the UE regarding support for HS2.0, and accordingly provides suitable selection policy and network discovery information to the UE.
