GGSN and Mobile IP Service in a Single System Configuration Example
Required Information
GGSN charging
characteristics (CC)
(optional)
PLMN policy
Ga Interface Configuration
Ga interface name
IP address and subnet
Physical port number
OL-22944-02
Description
Behavior Bits:If charging characteristics will be configured on the GGSN, behavior bits for the
following conditions can be configured:
GGSN use of the accounting server specified by the profile index
GGSN rejection of Create PDP Context Request messages
GGSN ceases sending accounting records
Each value must be a unique bit from 1 to 12 to represent the 12 possible behavior bits allowed for in
the standards. The default configuration is disabled (0).
Profile Index:If the GGSN‟s charging characteristics will be used for subscriber PDP contexts, profile
indexes can be modified/configured for one or more of the following conditions:
The number of statistics container changes is met or exceeded causing an accounting record
to be closed. The number can be configured from 1 to 15. The default is 4.
The up and/or downlink traffic volume limits are met or exceeded within a specific time
interval causing a partial record to be generated. The up and downlink volumes can be
configured from 0 to 1000000 octets. The interval can be configured from 60 to 40000000
seconds.
The up and/or downlink traffic volume limits are met or exceeded causing an accounting
record to be closed. The up and downlink volumes can be configured from 100000 to
4000000000 octets.
The number of SGSN switchovers is met or exceeded causing an accounting record to be
closed. The number can be configured from 1 to 15. The default is 4.
Specific tariff times within a day are reached causing an accounting record to be closed. Up to
four times can be configured using the hour of the day (1-24) and the minute (1-60).
Prepaid accounting can be disabled for a specified profile index.
The system supports the configuration of up to 16 profile indexes numbered 0 through 15
The GGSN can be configured treat communications from unconfigured SGSNs in one of the following
ways:
Treat the SGSN as if it is on a foreign PLMN
Treat the SGSN as if it is on a home PLMN
Reject communications from unconfigured SGSNs (default)
An identification string from 1 to 79 characters (alpha and/or numeric) by which the interface will be
recognized by the system.
Multiple names are needed if multiple interfaces will be configured.
These will be assigned to the Ga interface.
Multiple addresses and/or subnets are needed if multiple interfaces will be configured.
The physical port to which the interface will be bound. Ports are identified by the chassis slot number
where the line card resides in, followed by the number of the physical connector on the line card. For
example, port 17/1 identifies connector number 1 on the card in slot 17.
A single physical port can facilitate multiple interfaces.
