12.4 Connection setup
12.4.1 PS setup
This use case presents a simplified description of how to do a PS setup of a primary
PDP context from a module in the application processor.
12.4.1.1 General note on AT commands for PS setup
As described in section 7.6.4 on page 7-21, parameters for a PDP context family can be
manipulated on the BGAN XL Radio Module via an AT shell on the RM. In order to
create a telnet connection into the RM on which to issue commands to this AT-Shell,
an IP address is needed on the RM. This IP address is however not available until after
the PPPoE connection has been established (primary PDP context is activated).
This means that AT commands for PS setup that fall before activation of the primary
PDP context must be handled on the application processor and not the RM.
12.4.1.2 Define an activate PDP context
The first step in the setup procedure is to define the PDP context and QoS parameters.
This corresponds to the functionality of the AT commands +CGDCONT and +CGEQREQ
(see TS 27.007 [1]).
When the PDP context has been defined, activate it by starting a PPPoE connection
using above AT commands in the service name (7.6.3 on page 7-19):
Example:
XBB:AT+CGDCONT=2,ip,bgan.inmarsat.com;+CGEQREQ=2,3
Wait for the PPPoE connection to become active. If it fails, status parameters described
in 6.7.7.1 on page 6-42 can be used to determine the reason.
Once the PPPoE connection is active it is possible to telnet to the IP address of the
PPPoE end-point on the RM to get access to the AT shell. On this AT shell the primary
PDP context can be modified or secondary PDP contexts can be added / deleted /
modified (using +CGDCONT, +CGEQREQ, +CGEQMIN, +CGACT, +CGCMOD etc).
This AT shell is only valid as long as the PPPoE connection is active.
12.4.2 CS setup
To be able to dial out or receive incoming calls using the default CS configuration
(section 6.9.1 on page 6-56) of the BGAN XL Radio Module, you must setup the SIP
