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.


Service Processes

Saves the bills received by network

module to form original bills

Front disk module

Combines and sorts bills as required,

and transmits bills to back disk module

Bill processing module

Saves bills by channel to form final

bills and provides bills to billing center

Back disk module

Service Processes

Operation and Maintenance Process

The operation and maintenance process integrates the operability and

maintainability functions of the CG9812.

Dual-system Process

It starts and manages kernel process to implement functionality details

of the dual system.

Parameter Configuration Process

It’s the parameter configuration module of the CG9812. The CG9812

supports remote parameter configuration through the GUI of the

parameter configuration console.

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.


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.

prevent unauthorized access to the system. In doing

so, two user levels, including the administrator and

the common user, are defined and supported.

Log management

It enables the querying of

user operation records and

system operation records.


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.


Performance Management

The CG9812 performance management function measures

the following items:

Heartbeat

CPU usage

Physical memory available/total

Front storage available/total

Back storage available/total


Fault Management

Fault Management

System Self-Test

The CG9812 regularly tests itself on working conditions of hardware,

software as well as heartbeat, working environment, and so on.

Alarm Management

Detect and report in real time any fault or abnormity of the equipment

Generate audio and visual alarm signals through the alarm box

Present the alarm information as well as handling suggestion at the local

maintenance terminal to help troubleshoot the faults efficiently.

Trace Management

The CG9812 trace management function supports to trace protocol

messages and workflow messages.


Fault Management

Fault management helps to check, find and fix faults. Fault

management involves two aspects:

Alarm Management

Maintenance Management

Alarm management provides the following functions:

Detect and report faults or errors of the CG9812 in real time.

Remind you of audio-visual alarms through the alarm box.

Provide you with troubleshooting tips to fix faults.
