Abstract
An efficient interface for service exchange is provided between a circuit-switched communications network and a domain naming system (DNS) in a packet-switched communications network. A node in the circuit-switched communications network receives from a first entity a request for a first service involving a second entity associated with a second entity identifier. A message is sent from the circuit-switched network node to a DNS server in the packet-switched network requesting a second service related to the second entity identifier. The result of the second service from the DNS server is used in providing the first service.
