Specifies the timeout duration in seconds for RAN procedure timer in GGSN which is started on arrival of
every secondary ―Create PDP Context Request‖ message.
This is an optional keyword. If no timeout period is specified then default value of 10 seconds will be
assigned to timeout period.

must be an integer between 1 through 40.
Usage
Use this command to enable the RAN Procedure Ready feature for the particular GGSN service and to
specify the timeout period for RAN procedure timer in GGSN which is started on arrival of every secondary
―Create PDP Context Request‖ message.
Once a ―Create PDP Context Request‖ is received by GGSN from SGSN, a timer will be started at GGSN
and GGSN will wait till the Radio Access Bearer setup is completed and ―Update PDP Context Request‖ is
sent by SGSN. If any downlink data is received before arrival of ―Update PDP Context Request‖ or before
timer expire, that downlink packets will be queued or buffered. Currently buffer limit of sub-system is 1024
packets.
To support this feature each sub-session uses a common flag ‗ran procedure ready state‘, whenever a ―Create
PDP Context Request‖ is received for secondary PDP context and sub-session is allocated, this flag will be
set to TRUE by default. This common flag is checked while sending downlink traffic, if this flag is FALSE
then GGSN permit flow of downlink data but, if it is TRUE, GGSN will queue the downlink packets.
In case if the buffer becomes full ( total buffer limit is of 1024 packets) then, all the newly coming packets
will be dropped.
