After Logging into OSS, login to RNC (Procedure Described in Node B Part above)

>get RncCapacity . value (for checking capacity of RNC-Iubthroughput & user )

107

>strt (for checking status of Iublink, Cells, Transport Network whether ATM or IP &

RNC Module)

Explanation of Parameters:

CFRPHEM1: The first digit is the state of the Utrancell ,the next four digits show the state of the common channels (Fach/Rach/Pch/Hsdsch). The sixth digit (if present) represents the state of the EUL.

ICDS: The first digit is the state of the IubLink

The second digit is the state of NbapCommon signalling protocol.

The third digit is the state of NbapDedicated signalling protocol.

The last digit indicates status of sync.

(L means Locked, 0 means Disabled, and 1 means Enabled.) TN: Transport network (A means ATM & I means IP) MOD: RNC Module for a particular Iub Link

>Q[Quit] or bye (To exit from RNC or Node B)

108

>Lst UAP099 (To observe status of particular NODE B)

For working site: Adm status should be 1(unlocked) and Op. Status are normally 1(Enabled).

Otherwise they are 0.

For example: (i)

This signifies the site is Locked.

109 Example: (ii)

This signifies site is down

>lst iub_<iub number> [To see Iublink status of a Node B]

The first row represents Iublink status.

The second row represents synchronization status.

The last two rows represent nbap signalling protocol status. For IP site no need to check status of NBAP-C & NBAP-D

>Altk (To observe all alarms of a RNC)

110

Detailed alarm, alarm log & event log analysis will be given later on

>STD (used to check status of CC,DC & PDR)

Common Channel (CC), which deals with RRC, RLC, MAC-C for Common Channels

Dedicated Channel (DC), which deals with RRC, RLC, Ciphering, MAC-D for dedicated channels as well as Diversity Handling (DHO). This means that control signalling, circuit switched connections and packet switched data connections are handled by the same SP (Support Processor)

Packet Data Router (PDR), which deals with UDP/IP, GTP-U. Packet Data is mapped in both directions between Iu and UE . This RNC application uses AAL5. PDR is only implemented in the RNC modules of the main sub-rack. Only 5 PDRs are defined, irrespective of the size of the RNC

>cabl (to check temperature of Boards in RNC, Operational status of boards, load of GPB, SPB, SPM (SPM resides inside SPB boards). Load of GPB in slots MS-14 to 16, and in

ES-12 to 17 needs to be checked (depending on how many Extension Subracks are there. Load should be within 62%. )

> cedh (for checking ASE uses, Total Radio

Resources. Iublinks with hanging resources will be shown in the.bottom of the output )

111

for checking ASE uses, Total Radio Links & IubLinks with Hanging Resources. Iublinks with hanging resources will be shown in the.bottom of the Links & IubLinks with Hanging Resources. Iublinks with hanging resources will be shown in the.bottom of the command

112

---To solve this problem at first we need to block Iublink & then deblock it again. If problem not solved then check GPB_MODULE LOAD in which IubLink is located.

As described above It should be within 62%. If load is more than 62% then Change the Subrack of Iublink. For that use

 Resub Iub_(Iub no.) Subrack=ms or es-1 or es-2 as desired.

But before using resub we need to block IubLink. Then use resub command & then again deblock IubLink.

>lkra (used to see iublink located in different subrack than their ATM Port and Net module,net IubLink,net cell & avg. cell subrack wise. Care should be taken to maintain similar type load in each subrack. As already described use resub command to change subrack)

113

114

>cvls (to check last created cv, loaded cv, current package, whether autocreate , cv enabled or not, whether rollback status is on or not & total number of CVs. Total No. of should be less than 50 otherwise automatic backup will stop)

>st cs (for checking status of Iu-cs link. All op. state should be enabled)

*Note- If Iu-CS link is down then check corresponding ATM port. If it is also down check media upto GMGW. In this case customers can surf data but cannot make voice calls.

>st ps (for checking status of Iu-ps link. All op. state should be enabled)

115

*Note-If Iu-PS link is down then check corresponding ATM port. If it is also down check media upto SGSN. In this case customers can make voice calls but cannot surf data.

>st atmport (to check status of atm port. Specially atmport=ms-6-1/2/3/4 & ms-7-1/2/3/4 should be checked as it connected to Core network.

116

>pget 495 (to check error in ATM Port)

If pmSecondsWithUnexp value is continuously increasing then there is media issue

>pdiff 495& pdiff 1330 (for checking pmSecondsWithUnexp for 30 secs)

*Note- pget & pdiff commands can also be used at Node B end also

117

>sti (for checking IP pool of RNC. We can also check IpAccessHostGpb(Iub CP) of IubLink)

>get ‘3G site ID’ cid (To see cell id of cells in a NODE

>get ‘3G site ID’ primaryscramblingcode

*Note- Same scrambling code

>get ‘3G site ID’ location area

For Deleting & Creating IubLink 1 U- Command.

Finally copy the highlighted link appears in th Wndow

118

(To see cell id of cells in a NODE-B )

>get ‘3G site ID’ primaryscramblingcode (To get Scrambling Code of cells in a Node

Same scrambling code should not defined in nearby cells

>get ‘3G site ID’ location area (To see LAC of cells of a particular NODEB)

For Deleting & Creating IubLink 1^st use U+ command then use rdel iub_00001

Finally copy the highlighted link appears in the u- command & paste it to the WinFiol (To get Scrambling Code of cells in a Node-B)

(To see LAC of cells of a particular NODEB)

rdel iub_00001 & at last use

command & paste it to the WinFiol

119

>lst packet (to know the status of Packet Data Router)

>st ima (to know the status of imagroup) Most of the above commands can also be used at Node B end
