ETSI and CALEA Compliance Guide for Telecom Operators

Telecommunication providers operating within regulatory frameworks must adhere strictly to lawful interception standards, notably ETSI (European Telecommunications Standards Institute) and CALEA (Communications Assistance for Law Enforcement Act). This comprehensive guide details best practices to ensure compliance for telecom operators using S32 Technologies' InterceptPlus Telecom solution.

Understanding ETSI and CALEA Requirements

ETSI Compliance Overview

ETSI standards define technical specifications and procedures telecom operators must follow in the European region for lawful interception (LI). Key components include:

  • Handover Interfaces (HI): Clearly defined interfaces (HI1, HI2, HI3) for administrative information, intercept-related information, and content of communications, respectively.

  • Real-Time Delivery: Operators must deliver intercepted communications promptly and securely.

  • Security & Confidentiality: Ensure robust encryption, secure data handling, and strict access controls.

CALEA Compliance Overview

CALEA regulations mandate telecom operators in the United States to support lawful interception requirements by law enforcement agencies. Essential criteria include:

  • Call-Identifying Information: Provision of accurate caller identification and associated data.

  • Content Delivery: Ability to deliver intercepted communication content securely.

  • Access Control: Secure processes to manage intercept authorizations and maintain detailed audit logs.
