| Abstract(in English) | The IMS networks defined in the 3rd Generation Partnership Project (3GPP) provides a reliable caller’s identity presentation service to a callees. This service is achived by the authentication during SIP registration procedure and the authorization process at a originating SIP functional entity to populate an E.164 number for the authenticated user into the SIP request as a network-provided caller’s identity, which will be transparently sent to succeeding trusted SIP functional entities and finally to a callee. Therefore, for the inter-connection between IMS network where both networks implement a given set of procedures needed for provision of a reliable caller’s identity presentation service, there is no need to take measures against caller’s identity spoofing. However, for the inter-connection between IMS network and non-IMS network, some kind of solution to prevent the spoofing is needed, as the terminating side can use only user-supplied caller’s identity like e-mail in order to identify a caller. This paper reports a study on the applicability of the solutions for verifying the user-supplied caller’s identity currently studied in IETF STIR working group to the IMS networks. |
