Abstract
Techniques for supporting location services with roaming are described. A method of supporting location services (LCS) for a mobile station roaming from a home network and communicating with a visited network includes receiving a domain name system (DNS) query at a DNS of the home network from a packet data serving node (PDSN) of the home network. The method also includes sending to the mobile station from the DNS of the home network an address of a serving position determining entity (S-PDE) in the visited network.
