34 Background 4 Phase II, scheduled for October 1, 2001 –PSAPs are to receive more precise location identification, within 125 m of the caller’s location –location information could only effectively provided by technologies based in networks (using triangulation of the handset’s signal) 4 However –the current rules only permit network-based solutions to meet Phase II requirements –not economically or logistically feasible to upgrade or replace all current handsets to meet the date 4 Revised the rule to permit handset-based solutions
35 Revision to current wireless E911 Rules 4 Handset based location technology –Without respect to any PSAP request for Phase II Selling and activating ALI (Automatic Location Identification) capable handsets NLT March 1, 2001 50% of all new handsets activated are ALI capable NLT October 1, 2001 95% of all new digital handsets activated are ALI capable NLT October, 2002
36 –Once a PSAP request is received then Within 6 months or by October 1, 2001 –100% ALI-capable –Implement any network upgrade or other steps necessary to locate handsets –Begin delivering to the PSAP location information that satisfies Phase II requirements Within 2 years or by December 31, 2004, achieve 100% penetration of ALI-capable handsets
37 4 Network-based location technologies –Initial rule was implementation be fully accomplished within 6 months of PSAP request –Revised rules to deploy Phase II to 50% of callers within 6 Month and to 100% of callers within 18 months of PSAP request
38 Revised Location Accuracy and Reliability 4 For network-base solution: –100 m for 67 % and –300 m for 98% of calls 4 For handset-based Solution: –50 m for 67% and –150 m for 95 % of calls
39 Current E9-1-1 Standards Status 4 PN-3890: E9-1-1 Phase II –TR45.2 approved for ballot pending editorial review –Will move forward for 30-day Ballot –Publication: July 2000 4 PN-4288 –Temporarily on HOLD, due to –Ripple effects from PN-3890 –Waiting for the completion of PN-3890 –Will resume development from August 2000
40 LAES Ad Hoc Lawfully Authorized Electronic Surveillance
41 Background 4 TIA published J-STD-025 in 12/1997 –Defines interface between TSP and LEA to assist the LEA in conducting LAES 4 In March 1998, CDT and FBI filed separate challenges to the standard –FBI: J-STD-025 failed to incorporate “nine punch-list” items –CDT: objected to the J-STD-025 provisions on location and packet data
42 4 On August 26, 1999 –FCC adopted “Six” of the nine punch-list items Rejected CDT’s criticisms of the location and packet data – Reaffirmed Phase II schedule revise J-STD-025 to incorporate the six punch list items revision to be completed by March 30, 2000 “core” J-STD-025 provisions must be implemented by June 30, 2000 Industry must install “Six Punch-List” items and Packet- data capability by September30, 2001
43 Required Six Punch Lists 4 post-cut-through digits (also known as dialed digit extraction) 4 conversations of parities on hold 4 party join/hold/drop 4 subscriber-initiated signaling –use of flash-hook and other feature keys 4 timing information 4 network-generated signaling –notification that a line is ringing or busy
44 PN-4464 (to be J-STD-025-A) 4 Provides requirements for Phase II 4 Currently under Ballot Resolution 4 Scheduled for publication on Sep. 2000
45 CALEA JEM 4 JEM (Joint Expert’s Meeting) –current J-STD-025 raised significant technical and privacy concerns: Packet Technologies in the CALEA insufficient only authorized call-identifying information provided 4 FCC 3rd R&O requires delivering Packet- Mode by September 30, 2001 4 Sponsored by TIA & T1 (CALEA: Communications Assistance for Law Enforcement Act)
47 Authentication Focus Group 4 Initial Four Proposals for ESA were from –Certicom: EPAC –CipherIT: ESA –Lucent Technology: LAES –3GPP AKA 4 During the initial deliberation in TR45.2 –Certicom withdraws its proposal –AFG decided not to consider CipherIT proposal 4 3GPP AKA and Lucent Technologies
48 4 AHAG voted for 3GPP AKA and recommended 3GPP AKA to TR-45 4 TR-45 members voted for 3GPP AKA 4 TR-45.2 re-evaluated 3GPP AKA against ESA Stage 1 Requirements (PN-4392) 4 Some members proposed its evaluation against 3GPP AKA but TR45 endorsed. ESA: Enhanced Subscriber Authentication
49 4 The Recent Deliberation in TR45.2.2.AFG –3GPP AKA needs to determine the methods to provide “Home Control” –Need to determine the specific method for using CK to perform encryption –Assess AKA’s impact on performance and resources (e.g., traffic channel utilization) 4 TR-45 AHAG recommended SHA-1 as Local Authentication Algorithm and TR-45 endorsed it with no objection
