Abstract
In an IP Multimedia setting, a proxy server of a visited network receives a request for a geo-local service from a roaming user agent. The proxy server modifies the received request and forwards the modified request to the user agent's home network. The modification is such that the modified request or a related request message is routed back to the visited network from the user agent's home network, and the geo-local service requested by the roaming user agent is routed to an appropriate IMS entity in the visited network.
