Gn Interface

The interface between GSNs (including SGSNs and GGSNs) in the same PLMN is a Gn interface.

The interface between GSNs in different PLMNs is a Gp interface.

Gn interfaces are mandatory in GPRS and UMTS networks.

PORTNAME=Card1/Lan0;

EETH indicates an Ethernet electrical interface; FETH

indicates an Ethernet optical interface; ATM indicates an

STM optical interface.

Step 2 Configure the PFI interface.


Step 3 Configure the EPU process group. Configure the EPU process group.

ADD PROCESSGRP: SRN=0, SN=11, PSN=13, PROCGRP=EPUGP;

When configuring a process group, you must select the slot number for the per process. The mapping relations of slot numbers are as follows: 0 to 2, 1 to 3, 4 to 8, 5 to 9, 10 to 12, and 11 to 13.


Step 4.1 Set an IP address for the board. Set the IP address of the board.

ADD BRDIP: SRN=0, SN=11, MSTYPE=PRIMARY, IPT=IPV4,

IPV4=211.0.0.2, DESC=gtpc ip;

ADD BRDIP: SRN=0, SN=11, MSTYPE=SECONDARY,

IPT=IPV4, IPV4=211.0.1.2, DESC= gtpu ip;

You can set up to 48 addresses for an EPU.

You can set only one primary address for an EPU.


Step 4.2 Set the GTP-C IP address.

Set the GTPC IP address.

ADD BINDGTPCIP: IPT=IPV4, IPV4=211.0.0.2,

PTTP=PROTOCOL;

ADD BINDGTPCIP: IPT=IPV4, IPV4=211.0.0.2,

PTTP=LOCAL;

The GTP-C IP address must be selected from the IP addresses

of the boards.

The GTP-U address of the local type must be selected from the

addresses of the protocol type.


Step 4.3 Set the GTP-U IP address.

Set the GTP-U IP address.

ADD BINDGTPUIP: IPT=IPV4, IPV4= 211.0.1.2 ,

ITFDRT=GNGP;

ADD BINDGTPUIP: IPT=IPV4, IPV4=211.0.1.2 , ITFDRT=IUPS;

The GTP-U IP address must be selected from the IP addresses of the

boards.

The addresses of the Gn, Gp, and Iu-PS interfaces can be the same

or different from each other. You must set addresses for these

interfaces.


Step 4.4 Configure the public network segment. ADD PUBNWIP (optional)

ADD PUBNWIP: IP= 10.0.0.0 , MSK= 255.255.0.0;

You can set up to eight public network segments for the SGSN9810.

After public network segments are set, you can assign IP addresses that belong to the public network segments to the PFI interfaces.


Step 4.5 Set an IP address for the PFI interface. ADD IFIP

Using this command, you can set an IP address for each

interface of the PFI board

ADD IFIP: SRN=0, SN=11, IFTP=Physical, PN=0,

IPT=PRI, IP="10.0.0.2", MSK="255.255.0.0";

ADD IFIP: SRN=0, SN=11, IFTP=Physical, PN=0, IPT=PRI,

IP="10.0.0.2", MSK="255.255.0.0";


Step 4.6 Add static routes.

Configure a static route.

ADD IPRT: IP= 211.1.1.1, MSK= 255.255.0.0, GATE= 10.0.0.10,

PRE=40;

SGSN GGSN

GTP-C IP address: 211.1.1.1GTP-U IP address: 211.1.1.1

GTP-C IP address: 211.0.0.2GTP-U IP address: 211.0.1.2

Router

GW IP address: 10.0.0.10

IP address of the PFI port 10.0.0.2/10.0.0.4


Step 4.7 Set the default route.

ADD DFTRT

Using this command, you can set a default route for a certain

EPU.

ADD DFTRT: SRN=0, SN=11, GATE= 10.0.0.10;


Step 5.1: Configure dynamic routing: OSPF. SET OSPF

This command is used to enable OSPF.

Example:

SET OSPF: SW=ON;


Step 5.2: Configure dynamic routing: OSPF process. ADD OSPFPROCESS

This command is used to configure an OSPF process number. OSPF

supports multiple processes. Different OSPF processes do not affect each

other and run independently. The routing interaction between different

OSPF processes can be regarded as the routing interaction between

different routing protocols.

A process can contain multiple interfaces. An interface, however, can

belong to only one OSPF process. Multiple processes can be used to

isolate the routing domains of different interfaces.

Example:

ADD OSPFPROCESS: PID=1;


Step 5.3: Configure dynamic routing: OSPF area.

ADD OSPFAREA

This command is used to add an OSPF area and

configure the authentication type and area type for the

OSPF area. If area authentication is configured, running

this command is to use the same authentication mode

for all the interfaces in the specified area.

Example:

ADD OSPFAREA: PID=1, AREA="0.0.0.0", ATP=NULL,

AREATYPE=TRANSIT;


Step 5.4: Configure dynamic routing: OSPF network.

ADD OSPFNW This command is used to add the network segment and area in which the

interface running OSPF is located. If the IP address of the interface is within

the command-specified network segment, the interface runs OSPF. The

interface can be an EETH or an FETH interface.

Example:

ADD OSPFNW: PID=1, IP="10.0.0.2", MASK="0.0.255.255",

AID="0.0.0.0"; //Add an OSPF network to which an interface address

belongs.

ADD OSPFNW: PID=1, IP=" 211.0.1.2 ", MASK="0.0.0.0",

AID="0.0.0.0"; //Add an OSPF network to which a board address belongs.

Step 3 Configure the DNS server.

ADD DNSS ADD DNSS:IP= 211.13.1.1, PRI=PRI1;

The SGSN9810 supports configuration of up to six universal DNS servers and 32 special DNS servers.

Each DNS server has a unique priority.

Special DNS servers are only used to select DNS servers according to the APN-OI or PLMN in the PDP activation process.


Step 4 Configure mapping from the APN OI to the DNS server.

ADD APNOIDNSS ADD APNOIDNSS: APNOI= MNC000.MCC460.GPRS, IP=

Step 5 Configure the mapping from the PLMN to the DNS server. ADD PLMNDNSS

ADD PLMNDNSS: MCC= 460, MNC= 01, IP= 211.13.1.1, PRI=200;

If a specified PLMN is not configured with a corresponding DNS

Server, the SGSN9810 selects a universal DNS server.

Certain parameters, such as the timer and counter, are related to the configuration of the DNS sever.

Generally, DNS parameters need not be modified.

……


The flow of time calibration for the SGSN9810 is as follows:

The active OMU synchronizes its time with the NTP server

regularly and applies its time to the operating system of the active

OMU and the RTC of the rear board. If the NTP server is unavailable,

the OMU synchronizes its time with the RTC regularly and applies the

time to the operating system. The time calibration between the OMU

and NTP server adopts NTP. Between the OMU and RTC is a drive

interface.

Flow of Time Calibration


The standby OMU synchronizes its time with the active OMU regularly and applies the time to the operating system of the standby OMU and the RTC of the rear board. When the standby OMU synchronizes time with the active OMU, you should eliminate network delay on the active OMU. The NTP time calibration processing logic does not operate on the standby OMU. Only when the standby OMU switches to the active OMU, the NTP time calibration processing function is enabled. When synchronizing time with the standby OMU and the host, the active OMU obtains time signals from the RTC first.

The active OMU obtains time signals from the operating system only when failing to obtain time signals from the RTC.

Boards of the host synchronize time with the OMU regularly through NTP. If the communications between the host and the OMU fail, each board operates independently.

GGSN


Optional Routing Function of the GGSN9810

To increase the reliability of network and service operation

the active and standby mode to routing GGSN

DNS response multiple GGSN IP, 1 active+ N standby

load-sharing mode to routing GGSN

DNS response multiple GGSN IP which work in load-sharing mode


Optional Routing Function of the GGSN9810

To routing GGSN based on the IMSI segment

For example: select a GGSN for content-based charging.

To routing GGSN based on APNOI

When multiple carriers use one SGSN, each carrier can have its

own DNS server and make independent DNS resolving policies and

analyze the address to a particular GGSN.


Availability of Optional Routing Functions of the GGSN9811 The routing function of the active and standby mode and the

load-sharing mode is available only after the license is

obtained.

Selecting a GGSN based on the IMSI segment or selecting

a DNS based on the APN OI does not need support of the

license.


Selecting a GGSN According to the IMSI Segment Selecting a GGSN according to the IMSI segment

When a GGSN is selected according to the IMSI, the

SGSN9810 checks whether the signaling plane IP address of

the corresponding GGSN is configured according to the IMSI

of the user during the activation process.

If yes, the SGSN9810 does not initiate DNS resolving and uses

the IP address directly.

If not, the SGSN9810 queries the IP address of the

corresponding GGSN by constructing the APN and performing

DNS resolving.


Selecting a GGSN According to the IMSI Segment

The GGSN IP address based on the IMSI segment is

configured.

SET SERVICE_PARA: GGSN=YES;

ADD IMSISMCHAR: BEGIMSI= 460001234560000, ENDIMSI=

Selecting a DNS According to the APN OI

The SGSN9810 selects the DNS server according to the APN

OI.

ADD APNOIDNSS

ADD APNOIDNSS: APNOI= MNC000.MCC460.GPRS, IP=

211.13.1.1, PRI=30;

If a special APN OI is not configured with a corresponding DNS

Server, the SGSN9810 selects a universal DNS server.

ADD DNSS:IP="123.111.100.102", PRI=PRI6;
