Description
The name of the context configured on the system in which the processing of GTPP accounting
records is performed.
The context name is an identification string from 1 to 79 characters (alpha and/or numeric).
By default, the system attempts to use the same context as the one in which the GGSN service is
configured.
The port used by the GGSN service and the SGSN for communicating GTPC sockets for GTPv1. The
UDP port number and can be any integer value from 1 to 65535. The default value is 2123.
Mobile Country Code (MCC):The MCC can be configured to any integer value from 0 to 999.
Mobile Network Code (MNC):The MNC can be configured to any integer value from 0 to 999.
The GGSN can be configured with information about the SGSN(s) that it is to communicate with. This
includes the SGSN‟s IP address and subnet mask and whether or not the SGSN is on a foreign PLMN.
Multiple SGSNs can be configured.
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
.
