Lawful Access Industry Lawful Access Industry Challenges TodayChallenges Today
• Converging on a common global model and standards– Also capabilities for LAES beyond national law mandates (e.g., CALEA
in USA)• Effective distributed LI capabilities, especially for
– Small-scale access providers– Promiscuous local access points (especially WiFi® hotspots)
• Transnational capability implementations– Architectures and standards– Processes– Satellite systems
• Subscriber authentication and a common interface to stored data– Data retention requirements emerging in many countries– Costs of compliance with subpoena requests are dramatically
scaling for providers

Need to be revised to “plug into” TS 102 232 for handover, and with interoperable ASN.1
code modules
Work may be redundant with existing standards
and should be reviewed for termination Need to be revised to be
compatible with multiple appropriate application modules

TR-45 LAES Scope and TR-45 LAES Scope and Purpose of J-STD-025-BPurpose of J-STD-025-B
• Scope (excerpt)
…focus on a revision of the joint standard J-STD-025-A Lawfully Authorized Electronic Surveillance with the purpose of refining the current packet mode communications requirements for the interface to the Collection Function, represented as interface “e” in J-STD-025-A, a safe harbor specification. The packet mode communications surveillance definitions and requirements for stages 1, 2 and 3 are within the scope of the project…
• PurposeProduce a revision of J-STD-025-A containing the requirements for
support of packet mode communications surveillance.
GSC-9, Seoul
J-STD-025-B Work PlanJ-STD-025-B Work Plan
• Proposed standard Revision was balloted by both TIA and Committee T1
• J-STD-025-B was approved for publication as a TIA/T1 (ATIS) Trial-Use standard in December 2003, pending editorial review.
• The TR-45 LAES Ad Hoc recommended J-STD-025-B text for a 60-day ANSI ballot at the TR-45 March 2004 meeting. T1P1 and T1S1 have agreed to support and follow the decision of TR-45.
• J-STD-025-B in ANSI Balloting process

New LAES ProjectsNew LAES Projects
• TIA TR-45 approved two new LAES projects at its June 2003 meeting. Both were proposed as joint projects with T1 (T1S1 and T1P1).
• The 3GPP2 IMS/MMD Platform will be included in both new projects.
• The new projects were originally proposed as TIA/T1 Trial-Use level. A TR-45 LAES Ad Hoc recommendation to convert both projects to ANSI projects was submitted to the TR-45 March 2004 meeting.
GSC-9, Seoul
Proposed J-STD-025-CProposed J-STD-025-C
• Scope and Justification for Rev. C Project:This proposed revision is intended to include standard maintenance following J-STD-025-B
implementation fixes and improvements from field deployment and possible CALEA capabilities resulting from an analysis of Law Enforcement’s requirements expressed in various forms (e.g., Electronic Surveillance Needs for Carrier-Grade Voice over Packet service (CGVoP), IMS/MMD for 3GPP2 systems, support for TIA-835-C Mobile IPv6, support for Direct Signal reporting, circuit/packet terminology cleanup, support for MEID) and information related to additional Packet Mode technologies.
(Note: A copy of the CGVoP document may be obtained by going to http://www.askcalea.net> and clicking on the link in the lower left corner [“askcalea a question”]. When the dialog box comes up, type a request for a copy of the CGVoP document.)
Neither the requirements, messaging, protocol, or any additional text developed for the new revision of J-STD-025 is intended to conflict with other lawful intercept standards for CALEA.
NOTE: Bold, underscored text represents clarifications added since the original project approval by TR-45 Committee.
GSC-9, Seoul
Additional LAES Capabilities Additional LAES Capabilities ProjectProject
• Scope and Justification for additional LAES capabilities:
Produce a new TIA STD containing the messaging for support of additional LAES capabilities. Expected sources for contributions on these capabilities include, but are not limited to, distributed documents from Law Enforcement (e.g., Packet Surveillance Fundamental Needs Document (PSFND), Electronic Surveillance Needs for Carrier-Grade Voice over Packet Service (CGVoP)), previous ESTS contributions to the TR-45 LAES Ad Hoc Group (e.g., Surveillance Status, Continuity Check Tone, Feature Status, Non-communication signaling for information services), and carrier and vendor discussions with LEA (e.g., location tracking, Call Release information, LNP Considerations). Messages should be able to toggle on/off, as implementations of these capabilities are optional and to be provided upon request with negotiated terms. This STD assumes a J-STD-025 embedded architecture, messaging and protocol for communications surveillance. This standard is not being developed to meet the requirements of CALEA, and CALEA references are outside the scope.
NOTE: Bold, underscored text represents clarifications added since the original project approval by TR-45 Committee.
