2 © NOKIA FILENAMs.PPT/ DATE / NN SIP Needs Needs for Accounting Authentication Authorization Are these needs modular? Should they be?

3 © NOKIA FILENAMs.PPT/ DATE / NN Architecture Needed? Do we need to sketch out a roaming architecture for SIP where AAA is used, possibly in a modular way? Does multi-access make this interesting?

4 © NOKIA FILENAMs.PPT/ DATE / NN Examples ‘Simple’ 3GPP example WLAN roaming using 3 rd party service providers

5 © NOKIA FILENAMs.PPT/ DATE / NN General Requirements Ability To Integrate Different Networks, Services and Users Distribution of Profiles Updating SIP Server Entries Indication of Assigned Server User Deregistration SIP Server Allocation Ability to Provide Session Information to the Parties Involved Security

6 © NOKIA FILENAMs.PPT/ DATE / NN Authentication Authentication Based on SIP REGISTER Flexible Authentication Authentication Based on Policy

7 © NOKIA FILENAMs.PPT/ DATE / NN Authorization Ability to Authorize SIP Registration

8 © NOKIA FILENAMs.PPT/ DATE / NN Accounting Separation of Accounting Information Accounting Information Related to Session Progression Accounting Information Not Related to Session Progression Support for One-Time and Session-based Accounting Records SIP Session Changes Support for Accounting on Different Media Components Support for Cumulative and Non-Cumulative Accounting Configuration of Accounting Generation Parameters Ability to Relate SIP Session to Access Bearer Used Ability to Transfer Accounting Server Information
