Abstract: A mapping service in the mobile core network located after a packet data network gateway examines content requests from user equipment across a first PDN connection to determine if content associated with the content request is cached at an edge server outside of the packet data network. If the content from the packet data network is cached at the edge server, the mapping service redirects the user equipment to request the content from the edge server across a second PDN connection. By using a mapping service located after the packet data network gateway, the content requests may have already passed restrictions such as parental controls.

Abstract: Wireless offloading provides tools to a service provider to encourage or direct a subscriber to offload from a first network, e.g., a cellular network, to a second network, e.g., a Wi-Fi network. The cellular service provider can use network data to determine wireless offloading priorities for cellular subscribers on an individual or group basis. The cellular service provider may use wireless network data it has and/or wireless network data it learns about networks from the wireless devices (which may obtain Wi-Fi network data from beacon frames of Wi-Fi networks or active scanning and which may report to the cellular service provider). Each wireless device can be given scanning assignments to ensure that the reporting task is shared among subscribers or adjusted to fill in gaps in data. With the network data, the cellular service provider is capable of generating useful prioritized network lists for wireless devices, either individually or as a group.
