Why IP transport

IP is developing to allow the support of a mix of traffic types and to support low speed links.

The popularity of the Internet/World Wide Web and corporate LANs puts price pressure on IP networking equipment. the more economical IP network is preferred by a number of vendors.

Following the trend in network migration to protect your investment

SCTP layer in the protocol stack

Like TCP, SCTP is connection-oriented A connection-oriented protocol is one that requires a setup procedure to establish the

communication relationship (and state) between two parties In TCP, the communication relationship between two endpoints is called a

“connection” In SCTP, this is called an “association” this is because it is a broader concept than a

single connection (i.e. multi-homing) An SCTP association provides reliable data transfer of messages Messages are sent within a stream, which is identified by a stream identifier (SID) Messages can be ordered or un-ordered



Main features of SCTP Multi-homing support Multi-stream support Reliable data transfer



Multi-homing support Multi-homing can assist greatly in preventing single points of failure

Multi-stream support Streams are a powerful mechanism that allows multiple ordered flows of messages within a

single association. Messages are sent in their respective streams and if a message in one stream is lost, it will

not hold up delivery of a message in the other streams The application specifies the stream number to send a message on

IP Interface Board in NodeB

The DBS3800 of earlier versions has FE ports. Therefore, no hardware change is made.

To support the IP RAN feature, the BTS3812E and the BTS3812A require the NUTI board that can provide eight E1/T1 ports and two FE ports

Equipment data configuration

FG2 board works in stand alone mode

PEU board works in backup-binding mode MOD SUBRACK: SRT=RSS, PIUT14=FG2, REDT14=NO_Backup ,PIUT26=PEU,

REDT26=Backup_binding;

Remark:These boards may have other working mode depends on networking.


Configuring physical and data link layer

FE port settings: default values

%%LST ETHPORT: SRN=0, SN=14, PN=0, LstFormat=VERTICAL;%%RETCODE = 0 Execution succeeded.

List Ethernet Port Parameter---------------------------- Subrack No. = 0 Subrack name = RSS Slot No. = 14 Board type. = FG2 Port type = FE Port No. = 0 MTU = 1500 Self-confer = ENABLEFE port speed = <NULL> Duplex Mode = <NULL> Flow Control = <NULL> Act state = ACTIVATED(Number of results = 1)

--- END


Configuring physical and data link layer

FE port IP address:

ADD ETHIP: SRN=0, SN=14, PN=0, IPADDR="10.10.10.10", MASK="255.255.255.0", DETECTFLAG=DISABLED;

PPP link setting:

ADD PPPLNK: SRN=0, SN=26, PPPLNKN=0, DS1=0, TSBITMAP=all timeslot, IPADDR="20.20.20.20", MASK="255.255.255.0", PEERIPADDR="20.20.20.21", PPPMUX=Enable, AUTHTYPE=NO_V;

Remark:In this example, interface port IP will terminate the service.In a L3 network, a device IP is needed to terminate the service.


Add data on the control plane

NodeB information:

ADD NODEB: NodeBName="DBS3800-1", NodeBId=10, SRN=0, SN=2, SSN=0, TnlBearerType=IP_TRANS, IPTRANSAPARTIND=SUPPORT, IPAPARTTRANSDELAY=10, SharingSupport=SHARED;

NodeB algorithm parameter setting:

ADD NODEBALGOPARA: NodeBName="DBS3800-1", IubCongCtrlSwitch=ON;

SCTP server port information:

LST SCTPSRVPORT:; just use the default value

− NBAP service listening port No. = 58080

− M3UA service listening port No. = 2905

SET SCTPSRVPORT:; is an offline command.



ADD SCTP link for NCP,CCP

ADD SCTPLNK: SRN=0, SN=2, SSN=0, SCTPLNKN=10, MODE=SERVER, APP=NBAP, LOCIPADDR1="20.20.20.20", PEERIPADDR1="20.20.20.21", PEERPORTNO=8021, VLANFlAG=DISABLE;

ADD SCTPLNK: SRN=0, SN=2, SSN=0, SCTPLNKN=11, MODE=SERVER, APP=NBAP, LOCIPADDR1="20.20.20.20", PEERIPADDR1="20.20.20.21", PEERPORTNO=8022, VLANFlAG=DISABLE;

Remark:Peer ip address/port no should consistent with NodeB



ADD NCP/CCP port information

ADD NCP: NODEBNAME="DBS3800-1", CARRYLNKT=SCTP, SCTPLNKN=10;

ADD CCP: NODEBNAME="DBS3800-1", PN=100, CARRYLNKT=SCTP, SCTPLNKN=11;

Remark:1) CCP port no should consistent with NodeB2) When Huawei RNC and Huawei NodeB connected, one CCP link is enough. To be consistent with the 3GPP protocol, Huawei RNC&NodeB also support multiple CCPs, but it is not recommended by Huawei.3) The bandwidth of NCP&CCP is no need to be configured, the DSCP priority guarantees the signaling transmission


Add data on the user plane

Set traffic to path mappings

ADD TRMMAP: TMI=10, ITFT=IUB_IUR_IUCS, TRANST=IP, HDCONVPRIPATH=IPRT, HDCONVSECPATH=NULL, HDSTRMPRIPATH=IPRT, HDINTPRIPATH=IPNRT, HDBKGPRIPATH=IPNRT, HUCONVPRIPATH=IPRT, HUSTRMPRIPATH=IPRT, HUINTPRIPATH=IPNRT, HUBKGPRIPATH=IPNRT;

Remark:1) In this example, only 2 IP PATH configured, they are IPRT/IPNRT2) All R99 service use default settings3) All hsdpa/upa services mapped to RT/NRT path



Set active factor table

ADD FACTORTABLE: FTI=10, NAME="IUB", CCH=20, PSSTRM=75, PSINTERACT=75;

Remark:1) Value should get from network planning,2) Most of the parameters use default value



Set adjacent node information

ADD ADJNODE: ANI=10, NAME="DBS3800-1", NODET=IUB, NODEBID=10, TRANST=IP, TMI=10, FTI=10;

Remark:1) In V2.9, AAL2 and IP types of adjacent node are set by this

command.2) The purpose of this command is to set traffic map and active factor

attributes for the PATH of the questioned NodeB



Set port controller

ADD PORTCTRLER: SRN=0, SN=26, PT=PPP, CARRYPPPN=0, CTRLSN=2, CTRLSSN=0;

ADD PORTCTRLER: SRN=0, SN=14, PT=ETHER, CARRYEN=0, CTRLSN=2, CTRLSSN=0;

Remark:1) Port should bound to the SPU subsystem in a load sharing

way to increase reliability and better utilizing the resource in a balanced way.



Add IP PATH

ADD IPPATH: ANI=10, PATHID=1, PATHT=RT, IPADDR="20.20.20.20", PEERIPADDR="20.20.20.21", PEERMASK="255.255.255.0", TXBW=1984, RXBW=1984, VLANFlAG=DISABLE, PATHCHK=DISABLED;

ADD IPPATH: ANI=10, PATHID=2, PATHT=NRT, IPADDR="10.10.10.10", PEERIPADDR="10.10.10.11", PEERMASK="255.255.255.0", TXBW=30000, RXBW=30000, VLANFlAG=DISABLE, PATHCHK=DISABLED;

Remark:1) TX/RXBW configured is equal to physical link bandwidth or

maximum requirement bandwidth according to actual traffic2) The Physical Link BW is the minimum bandwidth of physical

link connection between RNC and NodeB.



Add IP route

In a layer 2 or PPP connection, no route is needed.

In a layer 3 network, route should set for both direction on interface boards.


Check the Iub status

Control plane

DSP IUBP:; to check the NCP/CCP port status.

DSP SCTPLINK:; to check the SCTP link status.

DSP PPPLINK:; to check the data link layer status.

DSP E1T1:; to check the physical layer status.

User plane

DSP IPPATH:; to check the IP PATH status.

PNG IPADDRESS:; to check the IP layer status of the PATH.

DSP FEPORT:; to check the FE port status.
