About MAPS™ MAPS stands for Message
Automation and Protocol
Simulation
It is a generic framework for the
generation of telecommunications
protocol messages and
transmission of bearer traffic.
MAPS™ is built on a proprietary
scripting language developed by
GL Communications.
All MAPS™ products come with
out-of-the-box scripts that act as
fully functional state machines for
the relevant protocol.
![Page 32: 5G Network Emulation Suite Presentation · 4 • End-to-End 5G Network Simulation • Simulates UE+gNodeB and AMF nodes. • Supports Control plane signaling and User plane traffic](https://reader033.fdocuments.us/reader033/viewer/2022050600/5fa932b910875273f2053e58/html5/thumbnails/32.jpg)
32
About MAPS™ Scripts: Scripts act as the state-
machine, or engine for a given call.
The logic of what messages to send
when is all contained in a script.
Messages: MAPS has an inventory
of generic Message Templates (ex:
Invite.txt) which it loads from the
hard drive when transmitting an
actual message. Messages are
completely customizable.
Profiles: Scripts and Messages are
kept as generic as possible. Specific
information (ex: Contact =
[email protected]) about a call
is sourced from .xml profiles
