GPS and BGAN Registration
BGAN uses the accurate position and timing information
obtained from GPS to help ensure efficient registration of a
BGAN Terminal with the BGAN network.
Dialing and Numbering
Dialing
- As the BGAN numbering system follows the same
pattern as the normal telephone system, dialing is carried out in
exactly the same manner as making a normal telephone call. The
subscriber number is used with the same international and area
codes as any other telephone network. Start the dialed number
with 00 and terminate it with #. If you are calling another
BGAN unit dial 00 + 870 number plus # to initiate the call.
Multi-Subscriber Numbering (MSN)
- The BGAN SIM card
has a master MS-ISDN number that is used for making voice
calls and sending SMS messages to another BGAN terminal.
PDP Context
A Packet Data Protocol (PDP) Context defines connection
aspects such as routing, Quality of Service (QoS), security and
billing between a mobile user terminal, such as the BGAN
Terminal, and a data network. PDP Contexts are essential to the
General Packet Radio Service (GPRS) system, which is used by
GSM and UMTS-based 3G networks worldwide for transmitting
data.
In order for a user to be able to transfer data across a network, a
PDP Context must be activated in the Terminal and associated
Core Network. The procedure for this is as follows:
1.
After registration with the network, the user activates a
PDP Context using an application on the computer or
Terminal, and requests sufficient radio resources (that is,
power and bandwidth) to support the context activation
procedure.
2.
Once the resources are allocated, the Terminal sends the
Activate PDP Context request to the Core Network. This
request includes key information about the mobile user's
PDP address (for example an IP address), PDP type (that
is, static or dynamic address) the QoS requested for this
context, the APN of the external network to which
connectivity is requested, the user's identity (IMSI) and
any necessary IP configuration parameters (for example,
security settings).
