Abstract
A mobile device may select between multiple networks in order to offload network traffic from one network to another. Policies under which network selection happens are established by network operators. A hierarchy of policy servers are established where a central policy server with policies established by a network operator can delegate authority for network switching to a local policy server with policies established by the same or a different network operator. The central policy server can establish criteria under which network switching or network selection is delegated to a local server. Policies from the local policy server can include information about local network conditions. A mobile device can use the policies from the central server and local server to select a network.
