Chapter 5: Software

Interface

Novatel Wireless™ has designed and developed a protocol which provides

facilities to monitor modem status while a data session on the host is active. In a

modem environment, modem status is typically accessed through AT commands

over the serial port. However, after a data session is activated on the host

through the modem, the serial port is deemed “in-use” and direct serial access

of AT Commands is not permitted. All data is now encapsulated through the data

session protocols.

The following items will be discussed within this chapter:

• wireline modem interface

• wrapper protocol

• pros and cons of the wrapper protocol

Revision 1.8 P/N 90023363

Point-to-Point Protocol Interface

A Point-to-Point (PPP) server implementation is supported within the GPRS module.

Remote Access Service (RAS) communication over the serial port is supported using the

AT commands to enter the PPP session and support PPP negotiation of IP and DNS

elements.

PPP negotiation will NOT complete until registration on the network has been completed.

In some cases, particularly where dynamic IP addressing is supported by the carrier, this

will not occur as it would be impossible to report an IP address until the unit had

performed the GPRS “attach request” on the network.

Status Interface

The Expedite and Merlin GPRS modem supports a method to retrieve modem status

information using AT commands while the modem is in a data session. This is

accomplished by using a unique driver called a Wrapper driver which exposes two serial

ports, one for data and the other for status. The Wrapper driver multiplexes or “wraps” the

information across the single serial or PCMCIA connection, and the data is then

“unwrapped” and routed to the appropriate location in the modem or over the air. This

allows status requests to occur in a separate stream to permit either the Novatel Wireless

Modem Manager or another user application to communicate with the modem. It is

anticipated that this approach will work for the majority of applications.

Revision 1.8 P/N 90023363

Wireline Modem Interface

All of the current Merlin based products implement a communication model that emulates

a wireline modem interface.

In a traditional modem model, users:

1. select the appropriate modem from the installation list

2. dial a number using that modem to contact their ISP

3. allow the host stack to establish a PPP session with another network entity.

Wrapper Protocol Overview

Novatel Wireless has created a protocol to provide facilities to monitor modem status

while a data session on the host is active. In a modem environment, modem status is

typically assessed through AT commands over the serial port. However, after a data

session is activated on the host through the modem, the serial port is deemed “in-use”

and direct serial access of AT commands is not permitted. All data is now encapsulated

through the data session protocols. The modem is limited in its processing of the

incoming data stream on the serial port to either passing the data along (as in a data

session) or processing it internally (as in AT commands).

180 Glossary

Revision 1.8 P/N 90023363

Connection Profile

See Network Connection Profiles on page 182.

dBm

dBm stands for decibels below 1 milliwatt. It is essentially a device’s signal output power

compared against a standard input signal strength of 1 (one) milliwatt. This number

represents a ratio and is expressed as a negative number (e.i. -60dBm)

Default Network Connection Profile

The default network connection profile is the connection profile, chosen by the user, that

the Modem Manager will use to connect to the network. The default network connection

profile can be thought of as the active network connection profile.

Direct Memory Access (DMA)

A fast method of moving data from a storage device or LAN device interface card directly

to RAM which speeds up processing. DMA by passes the CPU.

Domain Name

The name assigned to a computer or group of computers that constitute an IP network

domain. In general, a domain name is comprised of its local host name and its top-level

domain. The top-level domain can be made up of several names, each separated by a

period (.).

An example of a domain name is novatelwireless.com.

Domain Name System (DNS)

This is a network server used on IP networks, such as the Internet, for translating network

host names and Universal Resource Locators (URL’s) into IP addresses.

Domain Name System (DNS) Address

The IP (internet protocol) address of the Domain Name System (DNS).

Firmware

Firmware is a program or set of programs that have been set permanently into a computer

chip. The programs themselves usually are low-level programs that directly manipulate or

interact with the hardware. An example of firmware is your desktop computer’s BIOS.

Gateway GPRS Support Node (GGSN)

The SGSN communicates with what is called the Gateway GPRS Support Node (GGSN),

a system that maintains connections with other networks such as the Internet, X.25

networks or private networks.

GPRS

GPRS stands for General Packet Radio Service. GPRS is a high-speed data transfer

technique, used on GSM networks. It does not require that a continuous data stream be

opened between the data source and destination. Instead, it uses packet to move data

back and forth, making efficient use of the available radio spectrum.

GPRS Mobility Management and Session Management (GMM/SM)

Protocol stack between MS and SGSN that handles GPRS attach/detach and PDP context

activation/deactivation.

signaling.

GSM

GSM stands for Global System for Mobiles. It is an open, non-proprietary system with

international roaming capability providing seamless and same standardized same

number contact ability in more than 170 countries. GSM satellite roaming has extended

service access to areas where terrestrial coverage is not available.

GSM uses digital technology and time division multiple access transmission methods.

Voice is digitally encoded via a unique encoder, which emulates the characteristics of

human speech. This method of transmission permits a very efficient data rate/

information content ratio.

GSM-Data

See “Circuit Switched Data” on page 179.

Home Public Land Mobile Network (HPLMN)

The home network.

IMEI

IMEI stands for International Mobile Station Equipment Identity.

Internet Protocol (IP)

Internet Protocol works in conjunction with Transmission Control Protocol (TCP). TCP/

IP are part of a group of protocols that provide communication across interconnected

networks. TCP/IP is the protocol used on the Internet. The TCP protocol first

establishes a connection between the two systems in order to send and receive data,

and then breaks and sequentially marks the message into small packets. The IP

protocol routes and sends the packets based on the IP address.

Internet Control Message Protocol (ICMP)

IP network control protocol.

IP Addresses

As with personal computers that access the Internet, modems using GPRS technology

also have a dedicated Internet Protocol (IP) address, which is used to identify the node

or access point for the modem on the Internet. The service provider assigns this IP

address.

The 32-bit host address is usually represented in dotted decimal notation, e.g.

128.121.4.5. The address can be split into a network number (or network address) and

a host number unique to each host on the network and sometimes also a subnet

address.

IP Network

A network of computer networks that employ Internet Protocol allowing a user to

access the Internet, provided that the user has a modem; telephone line, cable line, or

wireless data network (e.g. CDPD); and a service provider.
