7.1 Overview

23.0323GPPRelease 16TSUniversal Geographical Area Description (GAD)

Tools: ARFCN - Frequency Conversion for 5G NR/LTE/UMTS/GSM

A bit string encoding a geographical description shall consist of the following parts:

– Type of Shape;

– Shape Description.

Such a bit string is usually part of an information element. The structure of the information element (e.g., element identifier, length) depends on the protocol in which the message containing the description is defined, and is specified in the protocol specification.

This organisation is illustrated in the example shown in figure 4.
