System Features
Multi-access
The CG9812 supports the simultaneous accesses from GSN
(GGSN/SGSN) with different versions.
Flexible CDR Format Conversion
The CG9812 allows you to configure and convert the CDR format.
Large Capacity and Powerful Processing Capability
Currently, the valid capacity of the hard disk configured for the CG is
enough to support 1,800,000 subscribers. The CDR processing
capability can be 3000 CDRs/second. The CDR data can be stored for
at least seven days in the CG.

System Features
High Reliability
The CG9812 employs two servers to compose a High Availability (HA) System
which supports auto-switchover between the primary and the secondary nodes.
The storage device is highly secured with 1+1 backup, each of which adopts
RAID5 +1.
Key interface/Path redundancy for the Ga interface and CG-BC interface.
Scalability
The CG9812 employs a modular structure.
To satisfy the requirement of increased system capacity, the following
measures can be considered, including adding CPU and memory, adding hard
disks, and so on.

Service Processes
Kernel Process
The kernel process is the core of the whole software. It acts as the
Transmission Control Protocol/Internet Protocol (TCP/IP) server for
the other processes. It is responsible for starting, stopping, and
monitoring the access point process and the operation and
maintenance process.
Access Point Process
Incorporates the main service functions of the CG9812, including CDR
reception, CDR processing, and CDR storage. The service functions
are integrated to be a network module, a front disk module, a CDR
processing module, and a back disk module.

Network Functions
Interface to GSN
CG9812 supports standard Ga interface to GSN, and collects CDRs
from GSN in real time through GTP’ protocol, and processes the
CDRs and output final CDRs which will be provided to the billing
center.
Interface to Billing Center
The CG9812 provides industry standard FTP/FTAM protocol interface
to the billing center. The CDRs can be transferred to the operator’s
designated billing center. Both pull mode and push mode can be
supported.
Copyright © 2006 Huawei Technologies Co., Ltd. All rights reserved. Page28
Services Functions
CDR Processing
Collecting CDRs
Collects CDRs from SGSN/GGSN. Currently, the supported CDR formats
include S-CDR, G-CDR, M-CDR, S-SMO-CDR, S-SMT-CDR, LCS-MT-
CDR, LCS-MO-CDR, and LCS-NI-CDR.
Pre-processing CDRs
Consolidating CDRs(Optional).
Sorting CDRs
– The CG stores the collected CDRs to different channels according to some
sorting condition.
Confirming CDR validity
– The CG supports CDR validity confirmation. The CG decodes the collected
CDRs.

Services Functions
CDR Processing
Storing CDRs
Original CDR storage
Final CDR storage
Auto-deleting CDRs
The CG supports auto-deletion of original and final CDRs. The original and
final CDRs are stored as files. The expired CDR files will be deleted
automatically. You can set the number of days the original and final CDRs
are stored. The default value is seven days.
Auto-backup CDRs
The CG supports auto-backup of original and final CDRs. After proper
configuration, the CDRs can be backed up to local or remote disks or other
storage media

Services Functions
Cluster System Function
Auto switchover
The CG supports auto switchover between active and standby servers.
Auto synchronization
The CG supports auto synchronization between the active and standby
servers. The active server can transmit the status information of the local
end to the peer end regularly.
Manual switchover
The CG supports manual switchover between active and standby servers.

Configuration Management
Configuration management is essential for the CG9812 and
has the following features:
Configuring the parameters through a graphical user interface
(GUI).
Configuring the parameters offline and remotely.
Only the administrator can configure the parameters.
Compare, back up, or restore the parameters.
