Question: In 3GPP-compliant networks, when Lawful Interception (LI) is authorized for location reporting, how does a Communication Service Provider (CSP) typically provide supplemental cell site location information to Law Enforcement Agencies (LEAs) for a given Cell Identity in an Intercept Related Information (IRI) report?
Option 1: By manually querying the LEA's database for matching cell site records.
Option 2: Through automated Cell Site Reporting (CSR) capability, utilizing data from the CSP's network engineering and planning facilities.
Option 3: By sending an SMS with location details to a designated LEA phone number.
Option 4: Via a periodic bulk transfer of all cell site information to the LEA, regardless of active intercepts.
Explanation: This is the correct answer because, when location reporting is authorized, CSPs can utilize an automated Cell Site Reporting capability to provide supplemental cell site location information to LEAs. This process leverages the CSP's internal network records to assemble and deliver the required geo-location or civic location information for each relevant Cell Identity in the IRI report, ensuring efficiency and accuracy.
