My TR TKÜV Notes
My Notes from edition 8.3 English (draft)
Scope
The Technical Guideline (TR TKÜV) sets out technical specifications implementing legal measures for telecommunications surveillance, cooperation in technical identification measures for mobile terminals and information provision.
See spec for additional details.
Content
Edition 8.3 differs from 8.2 by including further developments in ETSI TS 103 120 for the transmission of orders from authorized bodies of obligated telecommunication companies.
Edition 8.3 includes four Parts (A, B, C, and X):
- Part A. Technical implementation of legal measures for telecommunications surveillance This section describes the technical details of the surveillance equipment and the required technical characteristics of recording lines.
- Part B. Technical implementation of legal measures for information provision This section contains the technical details of the facilities for retrieving user, inventory and traffic data and in particular the optional procedure for transmitting the copy of the order to implement measures.
- Part C. Technical implementation of the legal obligation to cooperate in technical identification measures for mobile terminals This section contains the technical provisions enabling use of the technical means of the authorised agencies in public mobile networks to find certain information from mobile terminals and provide automated information on the identifiers temporarily and permanently assigned in a mobile network.
- Part X. Information Annex This informative section contains the planned further changes to the TR TKÜV which are to form the basis for a discussion of the next edition, supplementary information relating to Parts A and B of this edition, regulations for the registration and certification authority TKÜV-CA and a history of the previous editions of the TR TKÜV.
Definitions
§ 3.1 Telecommunications content (content of communication, CC) The part of telecommunication under surveillance that contains the content of communication exchanged between users or their terminals (such as voice, email or IP traffic).
§ 3.2 Intercept-related information (IRI) Data to be provided as per § 7 TKÜV on the further circumstances of the telecommunication under surveillance. These data must be provided even if the telecommunications content is not successfully transmitted (e.g. user busy).
§ 3.3 Surveillance copy According to Section 2(14) TKÜV, the duplicate of the telecommunication under surveillance to be transmitted (CC and IRI).
§ 3.4 Internet gateway The transmission route that serves for direct user-specific access to the Internet as per Section 2(12) in conjunction with Section 3(2) (first sentence) (3) TKÜV.
§ 3.5 OP telecommunications system -(OPT-S) As a general rule, the Obligated Party’s Telecommunications System is the origin of the telecommunication on the line under surveillance (LuS) for outgoing traffic and its destination for incoming traffic (such as subscriber exchange, UMS, email server).
§ 3.6 Transmission network The network used to transmit the surveillance copy from the OPTS to the authorised agency (CC and/or IRI).
§ 3.7 Concept Documents as per Section 170(1)(4)(a) TKG (TODO: get reference and add it here)
