  1. Brye Bonner Chair SA3-LI 3GPP SA3 Lawful Intercept

  2. Services Aspect (SA); Security (SA WG3); Lawful Intercept (SA WG3-LI) 3GPP Organization • UMTS, GSM. • 3GPP - WLAN IW 3GPP TS 33.106 (stage 1) GSM TR 01.33 3GPP TR 41.033 3GPP TS 33.107 Stage 2 Interworking GSM TS 02.33/03.33 3GPP TS 42.033/43.033 3GPP TS 33.108 Stage 3

  3. 3GPP Schedule for latest release • Release 6 developed over last 14 months • Frozen September 2004 • All 3GPP documents frozen at same time to allow manufacturers to develop product across all 3GPP standards. Partnership companies (ETSI is one) then ballot the release with or without national addendums. • Four times a year Plenary meets and approves change requests. Once approved by the plenary the document becomes stable and can be implemented if needed. • SA3-LI expects to freeze 33.106 (Stage 1) now. • Does not expect to change 33.108 (Stage 3) but is asking that it be left open until October • Is asking that 33.107 (stage 2) be left open to complete WLAN stage 2 work.

  4. Work Items for LI rel 6 • Justification: • to develop IP-based Services, which need to be addressed by lawful interception. SA WG3-LI will study IMS phase 2, Multimedia Broadcast and Multicast Services, Priority Service, Presence Service,Subscriber Certificates, and WLAN for possible lawful interception systems. • Objective • The objective of this work item is to create a lawful interception specification for the latest Rel-6 architecture and services as described in the above justification. • The enhancements to specification TS 33.108 addresses the additional work to specify the HI2 (Intercepted Related Information) and the HI3 (Content) interfaces for Packet Data, Circuit Switched and IMS delivery to the Law Enforcement Monitoring Facilities for 3G networks for Release 6. In the first step the 3G Packet Domain and phase 1 Multi Media Domain have been addressed in this specification for Rel 5. The Circuit-Switched Domain was already addressed by different regional specifications for 2G networks, and for 3G networks the Circuit-Switched Domain will be based on these documents and incorporated into Rel 6. HI1 (Administration) is not covered in this specification and is considered to be a matter of national regulation.
