Abstract
A method of enabling a legacy host, attached to a local network, to discover a service provided by a remote server. The method comprises the following steps to be performed by an IP Multimedia Subsystem Gateway within said local network. (1) Subscribing to an IP Multimedia Subsystem presence service and receiving presence information published by the presence service including Globally Routable User agent URIs. (2) Receiving a service discovery message sent by said legacy host. (3) Searching said presence information to identify a requested service and an associated Globally Routable User agent URI. (4) Sending a response to said legacy host including a local network address of the Gateway, whilst maintaining a mapping between said local network address and said Globally Routable User agent URI.
