Abstract
An access network discovery and selection (ANDSF) module includes a first transceiver that receives an service continuity signal from a service centralization and continuity application server (SCC AS). A first control module generates a preference and policy information signal based on the service continuity signal. The preference and policy information signal includes a list of access networks available for selection by a service request device (SRD). The first transceiver transmits the preference and policy information signal from the ANDSF module to the SRD.
