Carrying Location Objects in RADIUS and Diameter
Abstract
This document describes procedures for conveying access-network
ownership and location information based on civic and geospatial
location formats in Remote Authentication Dial-In User Service
(RADIUS) and Diameter.
The distribution of location information is a privacy-sensitive task.
Dealing with mechanisms to preserve the user's privacy is important
and is addressed in this document.
