Packet Data User Authentication; Tetra Network Protocol 1 - Motorola ST7500 Product Information Manual

Addressing
Description
Mode
Mobile Terminal applications use this address as the source address in IP
packets delivered to the infrastructure.
Local IP Address By default both Terminal Equipment and the radio have their own IP address-
es. Terminal Equipment and Mobile Terminal use these addresses for local
datagram transmissions between Terminal Equipment and Mobile Terminal
only and are not passed to the SwMI.
Static or Dynamic The terminals support static and dynamic IP address assignment. The dynam-
IP Address As- ic support is requested in the following situations:

Packet Data User Authentication

The Packet Data (PD) user authentication is a method of authenticating the Terminal Equipment user.
Authentication is done before allowing activation of the packet data link.
A PD Authentication server connected to the SwMI authenticates the Terminal Equipment user. The
terminal only sends the messages between the Terminal Equipment and the SwMI. In the wide mode,
the terminal offers Point-to-Point Protocol (PPP) user authentication between Mobile Terminal and
Terminal Equipment. The terminal uses Password Authentication Protocol (PAP) or Challenge
Handshake Authentication Protocol (CHAP), before the IP link is established. The terminal always
attempts to negotiate usage of the CHAP method. The radio agrees to use PAP when the Terminal
Equipment application insists. If the terminal does not require PD user authentication, it operates
without any user authentication. If the terminal requires the PD user authentication, it rejects the
Packet Data Protocol (PDP) context activation.
NOTICE: If the SwMI does not agree for the authentication method, for example PAP, the SwMI
can reject it.

TETRA Network Protocol 1

TETRA Network Protocol type 1 (TNP1) is a bridge protocol based on the TETRA layer 3 over the air
protocol. The TNP1 supports all TETRA dispatch functionality.
In the Trunked Mode Operation (TMO), the TNP1 specifies a protocol for use over the PEI, that allows
Terminal Equipment (TE) to have control over the TETRA services: mobility management, call control,
short data service, and supplementary services: send GNSS/GPS reports, software information, and
battery state information. In addition, commands to access the radio configuration and storage
parameters are available.
The radio supports TETRA standard packet data using the IP network layer protocol.
The radio operates on the single slot packet data channel.
Packet data applications reside internally, for example: GNSS/GPS reports, WAP, or in an external
device connected to the 8–wire RS232 data port on the radio. Communication to the external device is
initialized using AT commands.
The system provides point-to-point IP connectivity allowing the following datagram exchanges:
• Radio ←→ External Equipment (TE) (for example PC).
Request a Dynamic IP Address is set to Dynamic and the PD Applica-
tion Type is the radio internal PD application.
Request a Dynamic IP Address is set to Dynamic and the PD Applica-
tion Type is a PEI PD application requesting dynamic IP address.
