Feasibility study on IMS security extensions
Editor’s Note: The current version of this document represents the state of discussion in 3GPP SA3 after meetings #39 and #40. It consists of a compilation of input documents to SA3 #39 and SA3 #40. The annexes describe solutions proposed for signalling protection for fixed broadband access to IMS. They are based on input documents to SA3 #39 and SA3 #40 (S3-050402, S3-050539, S3-050571). Section 5 (Analysis) represents the contents of the analysis contributions discussed (S3-050333, S3-050372, S3-050427, S3-050570). The current text in section 5 is not endorsed by SA3 at this point of time.
The scope of the present document is to study security requirements and solutions related fixed broadband access to IMS. Both solutions for ETSI TISPAN NGN R1 and ETSI TISPAN NGN R2 need to be studied. Based on this document, solutions to meet the fixed broadband access security needs are to be specified in TS 33.203 within the time frame of NGN R1 and NGN R2.
