backbone

� APN defines the external PDN which is connected to GGSN,

such as the ISP network and enterprise network


APN — Structure

� APN OI defines the external network

� Transparent mode

� Fit for mobile operator acts as the ISP

� The IP address allocate to the MS belong to the operator’s network

� Generally, no need to authenticate the subscriber

� None transparent mode

� Fit for the mobile operator and ISP separate mode

� The IP allocate to MS belong to the operator or ISP

VPN — GRE

� GRE:

� Network tunneling protocol (Generic Routing Encapsulation), GRE

can enable data packets encapsulated to transport on the IP network

� When transporting in a tunnel, a packet needs to experience

the following two processes:

� Encapsulation process

� Decapsulation process

Gnif Data Configuration

� Gnif is used to identify the Gn logical interface and configured

on SPU board, it does not occupy the physical port. It is the

source IP or destination IP of the GTP package

� Step

� Create the Gnif interface, the slot number is the odd SPU slot number

ADD INTF: INTFN="gnif3/0/0";

� Configure the IP address and mask of the Gnif interface

ADD IP: INTFN=“gnif3/0/0”, IPADDR=“217.164.95.80",

MASK="255.255.255.255";

� Configure the GTP protocol parameter:

SET GTP: ESW=ON, INTV=60, T3=10, N3=5, PRISW=OFF, PRIID=0,

IDLSW=OFF, IDLE=48


Giif

LPU SPU

Physical interface

Gi interface

Data

Giif interface is used in Radius protocol stack

If the APN service requires authentication、accounting、authorization,

GGSN will send message to Radius after it receives PDP active

request from MS. In this message, the IP address is Giif IP.

If the APN doesn’t need AAA service, then this IP will not be configured

Giif interface

� Basic concept


Giif

� Giif is used to identify the Gi logical interface and configured

on SPU board, it does not occupy the physical port. It is just

configured when you have the AAA server

� Step

� Create the Gnif interface, the slot number is the odd SPU slot number

ADD INTF: INTFN="giif3/0/0";


ADD IP: INTFN=“giif3/0/0”, IPADDR=“10.99.77.10",

MASK="255.255.255.255";


Gaif

� Gaif is used to identify the Ga logical interface and configured

on SPU board, it does not occupy the physical port.

� Step

� Create the Gaif interface, the slot number is the odd SPU slot number

ADD INTF: INTFN="gaif3/0/0";


ADD IP: INTFN=“gaif3/0/0”, IPADDR=“10.99.75.3", MASK="255.255.255.255";

� GGSN is a router with GPRS function，so there are two kinds

of data to come in GGSN: the IP package (black line) which

sends to MS and ordinary data package (red line). None but the MS IP package needs to be transfer to Gnif interface to

conduct GTP encapsulation, ordinary data package needn’t


Gif� G interface is an inner interface of the equipment, it’s a

logical interface, identified by Gif.

� Step

� Create the Gif interface

ADD INTF: INTFN="gif0";

Reliability Networking� Basic Concept

� If the physical interface work abnormally, all of the service

connect to this equipment fail. The resolution is the reliability networking which can bind two physical interfaces together with

one Eth_trunk, the two interface work in active and standby

mode, if the active one failed, system can switch to the standbyinterface

� At most, one Eth_trunk can bind with 16 physical interfaces, but

for the reliability networking, it is recommended to bind only two

physical interfaces with one trunk

� One Eth_trunk has only one IP address, all of the interface bind

with the Eth_trunk has the same IP

� Eth_trunk is identified by the trunk id which is from 0~15

� Eth_trunk is a logical concept


Reliability Networking� Step (just give the interface connect to SGSN)

� Create the Eth_trunk logical interface

� ADD INTF: INTFN = "Eth-Trunk0";

� Active this Eth_trunk

� ACT INTF: INTFN = "Eth-Trunk0";

� Configure the IP address of this Eth_trunk

� ADD IP: INTFN = "Eth-Trunk0", IPADDR = "10.220.154.2",MASK =

"255.255.255.0";

� Set the Eth_trunk interface work in active and standby mode,

otherwise, all of the interface work in load sharing mode

� SET TRKHAMODE: INTFN="eth-trunk0";


Reliability Networking

� Create the ethernet1/0/0 interface that should bind with the

Eth_trunk0

� ADD INTF: INTFN = “Ethernet1/0/0";

� ACT INTF: INTFN = “Ethernet1/0/0";

� Create the ethernet2/0/0 interface that should bind with the

Eth_trunk0

� ADD INTF: INTFN = “Ethernet2/0/0";

� ACT INTF: INTFN = “Ethernet2/0/0";

� Bind the two physical interface with this trunk

� ADD ETHTRK: INTFN = "Ethernet1/0/0", TRKID = 0;

� ADD ETHTRK: INTFN = "Ethernet2/0/0", TRKID = 0;

GRE VPN Configuration

� Concept

� VPN instance

� It needs to create a VPN instance before using GRE, there are

three parameters bind with this instance

� VPN instance name (APN, interface, tunnel), G interface and Gi

interface may be included in the interface according to the

requirement

� APN is used to judge the route of the uplink data package;

G interface is used to judge the route of the downlink data package

Gi interface is used between GGSN and AAA server

Tunnel is used to encapsulate the subscriber’s data package



� Between different APN, APN and global route is

separate entirely, they are sightless with each other

Other Billing Methods

� Besides G-CDR, GGSN supports radius charging, content charging and prepaid

� Radius charging� In active procedure, GGSN will send a charging request package to

Radius, active succeed after its response, service is running, GGSN must inform Radius often of data package usage

� Content charging� It’s analyze the subscriber’s service IP package deeply to master

usage of the subscriber on different service. Billing center shall charge according to different service

� Prepaid � In active procedure, GGSN send service usage to SCP to charging



GGSN Charging Principle

GGSN Charging Data Configuration


Data Configuration Procedure� Configuration procedure

� Confirm charging version

� Confirm optional field which is provide in CDR format

� Confirm normal charging characteristic

� Confirm generated condition of partial CDR in three charging

characteristic

� Confirm processing to charging characteristic in the three user

mode

� Confirm information of CG

� Confirm tariff parameters


Data Configuration Procedure� Confirm charging version

� Command: SET CHARGE:;

� This command should consult with the peer CG

� Confirm optional field which is provide in CDR format


� Optional field is O and C attribute field of CDR which is defined

in protocol, it will be configured by operator’s choice

� Confirm normal charging parameter


� Including node ID, alarm threshold, time zone and generated

condition of partial CDR


Data Configuration Procedure

� Confirm generated condition of partial CDR in three

charging characteristic

� Command: SET CHGTHRSHOLD:;

� If this command is not configured, then use the

information configured in “SET CHARGE”

� Partial CDR has different generating condition of the three

charging characteristic



� Set the APN-based or global-based charging

characteristics

� In three user mode, confirm its processing on charging

characteristic

� Command: SET CHGCHARAC:;

� GGSN divide user area to home subscriber, roaming subscriber

and visiting subscriber

� MS will get the charging characteristic from SGSN, otherwise,

from GGSN



� When a problem occurred on the charging server,

GGSN9811 uses a method called Radius charging

message retransmission to prevent the G-CDR from

losing

� SET RADIUS

� SET RADIUS : RETRY=3, TIMEOUT=10;

� LST RADIUS

� RMV RADIUS



� Confirm information of CG

� Command: SET CG:;

� GGSN selects CG of different priority by data

configuration

� Confirm tariff parameters

� As same as the procedure in SGSN


Data Configuration Procedure� SET FESTIVAL

� E.g.

� SET FESTVL: YEAR=2004, MONTH=1, DAY=1;

� LST FESTVL;

� RMV FESTVL: YEAR=2004, MONTH=1, DAY=1;


Data Configuration Procedure� SET WEEKDAY

� Define the workday and weekend in one week

� E.g.

� SET WEEKDAY: WKD=MON, TP=WORK;

� SET WEEKDAY: WKD=TUE, TP=WORK;

� SET WEEKDAY: WKD=WED, TP=WORK;

� SET WEEKDAY: WKD=THU, TP=WORK;

� SET WEEKDAY: WKD=FRI, TP=WORK;

� SET WEEKDAY: WKD=SAT, TP=WEEKEND;

� SET WEEKDAY: WKD=SUN, TP=WEEKEND;

� LST WEEKDAY:;



� SET TARIFF

� Define the tariff for different days.

� E.g.

� SET TARIFF: TP=WEEKEND, ST=0, ET=7;

� SET TARIFF: TP=WORK, ST=7, ET=21;

� SET TARIFF: TP=FESTIVAL, ST=21, ET=23;

� LST TARIFF:;

� RMV TARIFF:;



� SET CG

� Add CG information which is connected with

GGSN9811

� E.g

� SET CG: IP="10.3.10.4", GRD=0, TP=UMTS;

� Related commands:

� LST CG:;

� RMV CG: IP="10.3.10.4";


Summary

� After this slides, you know the important part and parameter

of the data configuration, and you can complete the

exercise in the trainee’s manual
