3 SRHO Functional Requirements Architectural Considerations For WiFi<>WiMAX SRHO use WiMAX Forum WiMAX-WiFi IWK Architecture For WiMAX<>xG (2G/3G/4G) use WiMAX Forum IWK Architecture For other use cases specify the architecture and general mechanism for SRHO Protocol Considerations Define Rx and Ry interfaces for WiFi<>WiMAX SRHO Define R9 interface for WiMAX<>xG SRHO Use MIH Protocol for L3 tunneling. Define complete details in specification. Cell Selection/reselection Define the cell selection and reselection criteria for active/idle mode Define measurement report format and measurement parameters used to initiate Single/dual radio HO between different access networks. Network Discovery and Selection Define mechanisms that assist the mobile device to detect the presence of WiFi SFF and WiMAX SFF and their services before attaching to the access network (independent of single/dual radio HOs) Define mechanisms/criteria that assist the mobile device to select appropriate WiFi and WiMAX. Specify what is needed from access network. Define mechanisms that assist the mobile device to know if the network supports Single/Dual radio HO
