Abstract
Anchoring a communication session for a mobile node involves a signaling node that intercepts a routing information request sent by a switching center of a circuit-switched network. The routing information request requests routing information for the communication session. Subscription information associated with the mobile node is retrieved. Whether the mobile node is eligible to be anchored in a packet-switched network is established. Anchoring of the communication session in the packet-switched network is initiated if the mobile node is eligible to be anchored in the packet-switched network.
