Secure XDM communication between IMS networks

摘要

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.

1. A method of communication for XDM requests between first and second IMS network domains, the method comprising:
receiving an XDM request in the first domain, the XDM request comprising a request for access to an XML document from a location in the second domain; creating a SIP request, the SIP request including information identifying it as a request that relates to an XDM request; and sending the SIP request 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 and thereby establish a connection for XDM requests between the first and second domains; wherein the SIP request is a SIP INVITE MESSAGE comprising a request to establish an SDP negotiated SIP session between the first and second IMS network domains; wherein the SIP INVITE MESSAGE comprises an IMS service indicator indicating that the SIP request relates to the XDM request; and wherein the XDM request is sent to the location in the second domain using the SIP session that has been established.
