February 24, 2004 TR-45 Lawfully Authorized Electronic Surveillance (LAES) Packet Solutions Industry Meeting March 19 th, 2004 Terri L. Brooks Chair TR-45 LAES Ad Hoc

2 J-STD-025 and J-STD-025-A Packet Solutions  PacketEnvelope Message –intended for low-volume packet communications (e.g., SMS)  Sending packet stream –intended for high-volume packet communications –allows for, but does not require, separation of information based on type of court order –no specific guidelines given on stripping out unauthorized information

3 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.

4 J-STD-025-B  Transport systems approach J-STD-025-B follows a “transport-based” approach rather than a “services” approach, as proposed by Law Enforcement. Services evolve at a high rate, may be configured differently by different service providers, and may have different nomenclature used to refer to services, making it difficult to specify a long-term approach. In addition, the TR-45 LAES group does not attempt to dictate which services and/or platforms CALEA applies to, but provides the specifications necessary for a given technology to provide information to Law Enforcement in a standardized way for systems determined to be covered by CALEA.

6 J-STD-025-B Work Plan  Following the ballot and default ballot by both TIA and T1, one unresolved NO vote remained in the T1 ballots from Law Enforcement (FBI). Law Enforcement was notified of their right for appeal, but did not appeal.  J-STD-025-B was approved for publication as a TIA Standard/T1 (ATIS) Trial-Use standard in December 2003, pending editorial review. The document has been published.  TR-45 approved J-STD-025-B for a 60-day ANSI ballot. The close date for TIA is May 7, The close date for ATIS (T1) is April 14, 2004.

7 Standards Coordination for J-STD-025-B (cont)  TR-45.6 cdma2000 ® technology — submitted detailed text for stages 1, 2, and 3 for inclusion in J-STD-025-B  T1P1 GPRS/UMTS—normative references for detailed solution submitted for inclusion in J- STD-025-B  T1S1– normative references for detailed solution submitted for inclusion in J-STD-025-B

8 J-STD-025-B Section 4.9  Section 4.9 Packet Mode Technology added to describe the Packet Data LAES.  Provides ability to send communication-identifying information (CII) only, or CII in addition to call content (CC).

9 J-STD-025-B cdma2000 ® LAES Messages  cdma2000PacketDataSessionEstablishment –reports the successful or unsuccessful establishment of a packet data session  cdma2000PacketDataSessionTermination –reports the end of a Simple IPv4, Simple IPv6, or Mobile IPv4 packet data session  cdma2000PacketDataInterceptStart –reports the start of interception for each known established packet data session if the information is reasonably available at the IAP

10 J-STD-025-B cdma2000 ® LAES Messages (cont.)  cdma2000PacketDataServingSystem –reports the identity of the system currently serving the intercept subject  cdma2000PacketDataPacketFilter –reports the setup/change/release of a particular packet filter used to map downlink (forward direction) traffic to the MS  cdma2000Interception of Content –The cdma2000 ® lawful interception correlation (CLIC) header is prepended to each interception packet before the intercepted packet is transported to the LEA.
