Lawful Access Industry
Challenges 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

TR-45 Lawfully Authorized
Electronic Surveillance
(LAES) Activity
Cheryl Blum, Chair TR-45
2016-04-05
TR-45 LAES Scope and
Purpose 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…
• Purpose
Produce 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 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.

submitted detailed text for stages 1, 2, and
3 for inclusion in J-STD-025-B
• T1P1 GPRS/UMTS—references for
detailed solution submitted for inclusion in
J-STD-025-B
• T1S1– references for detailed solution
submitted for inclusion in J-STD-025-B
GSC-9, Seoul
New 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-C
• Scope and Justification for Rev. C Project:
This proposed revision is intended to include standard maintenance following JSTD-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
Project
• 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 CarrierGrade 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 TR45 Committee.
