private network IP address not routable within the Internet) and others provide a routable public IP
address.
Static IP Address: A static IP address is assigned by service providers to BGAN Users when the USIM is
provisioned. This static IP address is used every time you connect to the BGAN network and is
associated with a specific username and password.
DHCP Address: Local IP address that is assigned by the UT DHCP server to the TE once connected to the
UT. This is a private IP address that is not routable within the Internet.
Terminal Local IP Address: IP address of the UT to access the Web MMI and talk to the UT via Telnet.
This address is configurable by the user.
Standard Connection: A standard connection is charged by volume of data sent. The bandwidth you are
allocated depends on terminal type and network availability, but is always "best effort," that is, you are
allocated bandwidth depending on your requirements and the requirements of other users of the BGAN
network or BGAN terminal. This connection class is suitable for most data types other than multimedia.
Streaming: A streaming connection is charged by time. You are charged for the amount of time the connection
is active. Streaming enables multimedia data, such as video, to be sent in a continuous data stream and
converted into sound and pictures. The bandwidth required for a streaming connection is difficult to predict,
and depends on factors such as length of connection and number of receivers.
Symmetrical Rate: The rate at which streaming data is transmitted, in kilobits per second (kbps). This rate
applies to transmitted (uplink) and received (downlink) data.
Desired Symmetrical Rate: From the drop-down list, choose the desired data rate for your Streaming
connection. This can be 32 kbps, 64 kbps, 128 kbps, or 256 kbps. This figure is guaranteed, unless the
connection cannot meet this requirement because of bandwidth restrictions. In this case, the rate defaults
to the minimum symmetrical rate.
Minimum Symmetrical Rate: From the drop-down list, choose the minimum data rate that you are
prepared to accept for your streaming connection. This can be 32 kbps, 64 kbps, 128 kbps, or 256 kbps.
This rate must be lower than the desired symmetrical rate. If the connection cannot meet this
requirement, an error message displays.
Terminal Equipment (TE): Terminal equipment refers to the piece of equipment connected to the BGAN UT
(laptop, video equipment, phone, etc.)
Traffic Flow Template: A traffic flow template, also called an application template, is a series of data filters such
as QoS, PDP context, and security settings that allow the core network to classify packets received from an
external network into the correct PDP context. When incoming data arrives at an access point in the core
network, a packet classifier will make a PDP context selection based on the traffic flow template, and map the
incoming data packets into the PDP context with the correct QoS attributes. The use of a traffic flow
template allows multiple PDP contexts to be associated with the same PDP address.
User Terminal (UT): The user terminal is the BGAN modem device, that is. the IDU.
USIM Card: Your BGAN service provider supplies you with a Universal Mobile Telecommunications System
Subscriber SIM (USIM) card.
The USIM card is similar to the SIM card commonly used in a GSM phone. The card holds a microchip that
stores information and encrypts voice and data transmissions, making it extremely difficult to listen in on calls.
The USIM card also stores data that identifies the caller to the BGAN service provider.
Virtual Private Network: A Virtual Private Network (VPN) enables remote offices or users to gain secure
access to their organization's network over the public telecommunications network. This provides the benefits
of remote access without the expense of dedicated leased or owned lines. VPNs work by using tunneling
protocols to encrypt data at the sending end, and decrypt the data at the receiving end. This "tunnel" cannot
be accessed by data that is not properly encrypted.
