Overview
ISO/TR 11769:2010 is an informative Technical Report that reviews data retention (DR) provisions in the context of Intelligent Transport Systems (ITS) and the Communications Access for Land Mobiles (CALM) family of standards. The analysis is made with respect to Directive 2006/24/EC and focuses on IPv6 domain services offered by CALM/ITS. The report explains how retained data categories identified by the EU directive relate to CALM deployments and highlights the roles and responsibilities of Communications Service Providers (CSPs) and Law Enforcement Agencies (LEAs).
Key Topics
- Scope and purpose: DR is primarily to support LEAs in criminal and terrorist investigations; it can also assist other societal functions such as locating missing persons.
- Reference framework: The report maps data categories from Directive 2006/24/EC to CALM/ITS capabilities and notes where CALM provides or lacks the necessary constructs.
- CALM characteristics: CALM is presented as a data-only network that provides IPv6 connectivity over multiple wireless access media and offers an abstraction layer for link technologies.
- Retained data examples: The report identifies how CALM/ITS may provide data such as user IDs, IP addresses, timestamps (log-in/log-off), Station-ID, Cell ID, IMSI and IMEI where applicable, and IPv6 header fields.
- CSP obligations: CSPs operating PLMNs or providing home-agent-like services are expected to meet DR and lawful interception (LI) obligations, maintain data integrity, and report DR system failures.
Applications
ISO/TR 11769:2010 has practical value for:
- CSPs implementing ITS/CALM services who must map service elements to retained-data categories and design secure retention storage and handover mechanisms.
- LEAs and supervisory authorities that need to understand what retained data CALM/ITS deployments can realistically supply (e.g., location labels, subscriber identifiers) and how IPv6-based services are affected.
- Policy makers and regulators who require a technical perspective on how Directive 2006/24/EC applies to evolving ITS access media and mobility services.
Benefits include clearer compliance mapping for DR, guidance on data integrity and reporting expectations, and improved coordination between CSPs and LEAs for lawful access to retained data.
Related Standards
- Directive 2006/24/EC (EU Data Retention Directive) - primary legal reference used in the report
- CALM family standards (ISO/TC 204) - underlying ITS communications and access media specifications
- Relevant PLMN standards (GSM/UMTS/CDMA, satellite, emerging access technologies) - where CSP-originated subscriber records may satisfy DR requirements
