1. 1 Michael Clayton 3GPP SA EMTEL Workshop Priority Service Activities 26-27 February 2002

2. 2 Agreed to Perform a Feasibility Study –Outline the technical requirements –Identify the scope of work required –Perform a gap analysis to determine the extent existing 3GPP specifications can support these Priority Service requirements The Work Item Description (WID) will then address all the necessary changes to 3GPP specifications to satisfy Priority Service requirements Priority Services

3. 3 Approved at TSG-SA#13, Beijing, China –24-27 September 2001 (SP-010523) Supported by –AT&T Wireless –Cingular –National Communications System –SBC Communications –Telcordia Technologies –VoiceStream WID allocated to SA Working Group 1 Priority Services Work Item

4. 4 End-to-End Service –Informative Annex: ITU-T Recommendation E.106 Scenarios –Mobile-Mobile –Mobile-Fixed –Fixed-Mobile Priority Services WID

5. 5 Identify high-level requirements of Priority Service Determine existing relevant 3GPP specifications that support Priority Service requirements Perform Gap Analysis –Assess the ability of existing 3GPP specifications to meet the Priority Service requirements Feasibility Study – A Multi-Step Process

6. 6 Priority Call Origination Priority Call Termination Priority Progression Priority Queuing Priority Level & PIN Invocation on Demand Applicable to Voice & Data Authorized by Subscription Authorized by PIN Priority Service Feature Code Priority Service Supported during Intersystem Roaming Priority Service Supported during Intersystem Handover Priority Service Call Detail Record High-Level Requirements
