| cgprsGtpT3TunnelTimer |
.1.3.6.1.4.1.9.10.48.1.1.1.1 |
|
The T3-TUNNEL timer for mobility management. This timer is
started by the 'Old SGSN'. Whilst the timer is running, the
T-PDUs received by the 'Old SGSN' (from the GGSN), and any
buffered T-PDUs are forwarded to the 'New SGSN'.
|
| cgprsGtpT3ResponseTimer |
.1.3.6.1.4.1.9.10.48.1.1.1.2 |
|
The T3-RESPONSE timer for retransmission. This timer is started
by GGSN, upon the transmission of a signalling request message; it is
used for message retransmission purposes, in the event that no response
is received by the time the timer expires. Note that the total wait
time (cgprsGtpT3ResponseTimer*cgprsGtpN3Requests) must be shorter than
the Mobile System (MS) wait time between retries of Attach and RA
Updates; The product of cgprsGtpT3ResponseTimer and cgprsGtpN3requests
must be less than the minimum value of the Attach Timer(T3310) and the
Routing Area Update timer(T3330). The cgprsGtpT3ResponseTimer timer,
according to the standards, recommends an adaptive back-off mechanism,
using increasing values, e.g., 1, 2, 4, and 8 seconds.

Charging Gateway table. Charging information in GPRS
is collected for each MS by SGSNs and GGSNs that are serving
the MS. The information that the operator uses to generate
the bill to a subscriber is operator-specific, such as
usage of the radio interface, PDP addresses, duration of
PDP context, usage of general GPRS resources, location of
MS, traffic distination, usage of external data network
and so on.
Charging Gateways act as a storage buffer for real time
Charging Data Record (CDR) collection. It provides the
CDRs to the billing system.
Charging Gateway Table lists all the charging gateways
and their operational states. Backup charging gateway type
is not allowed if there is no primary charging gateway type
entry in the table. In addition, there is only one primary
charging gateway entry.

|
| cgprsGtpGSNTable |
.1.3.6.1.4.1.9.10.48.1.2.1.12 |

GSN peer table. The SGSN-GGSN peer relationship is established
as following:
o A table in DNS listing the APN and corresponding ip
address of GGSN.
o When Mobile System (MS) wants service, it sends packets to
a SGSN with specific APN.
o SGSN asks DNS for ip address of a GGSN that service this
APN.
o DHCP returns a GGSN.
o SGSN requires a path to the GGSN using GTP protocol.
o The SGSN and GGSN peer maintains path by sending echo
request message to each other. If one side fails in echo
reply for certain times, the other side will send a trap to
NMS.
Note:
o Multiple-Multiple peer relationship, i.e. a SGSN have
multiple GGSN as peers, while a GGSN have multiple SGSN
peers, depending on routing path.
o Path is kept in database.
