Abstract

Requests between first and second IMS network domains are communicated by receiving an XDM request in the first domain. The XDM request relates to an XML document that can be accessed via the XDM request from a location in the second domain. A SIP request is created that includes information identifying it as a request that relates to an XDM request. The SIP request is sent to the second domain so that the SIP request can be routed to the location in the second domain based on the identifying information in the SIP request. A connection for XDM requests between the first and second domains is established.
