GPS and BGAN Registration
ISDN
Dialing and Numbering
PDP Context
BGAN uses the accurate position and timing information
obtained from GPS to help ensure efficient registration of a
BGAN Terminal with the BGAN network.
The Satellite Terminal provides an ISDN (Integrated Services
Digital Network) interface to connect devices for Circuit
Switched voice and data services. It is a Basic Rate (also known
as 2B+D) interface and uses the Euro ISDN protocol. Note that
the Satellite Terminal can only provide service for one 64Kbps
B-channel at a time.
Dialing - As the ISDN 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 a #.
Multi-Subscriber Numbering (MSN) - ISDN supports Multi-
Subscriber Numbering (MSN). MSN is a facility whereby more
than one telephone number can be allocated to an ISDN line.
The BGAN Satellite Terminal assigns different MSNs for Voice,
3.1KHz Audio, UDI and RDI devices. Each incoming call will
be directed to the appropriate MSN depending on the type of
call. This allows proper routing of incoming calls to the correct
ISDN device (e.g. ISDN phone, data card or Fax).
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:
