About this document

The purpose of this document is to describe the alarms and alarm handling of the Nokia UltraSite WCDMA Base Station (BTS) family, the Nokia MetroSite WCDMA Base Station and the Nokia MetroSite 50 WCDMA Base Station. BTS software (SW) uses t hese alarms as a basis for internal diagnosis and fault reporting through the Ra dio Network Controller (RNC) to the Operations Support System (OSS) and BTS Site Manager.

Alarm handling General

Base Station (BTS) alarm handling is based on unit state information. It prevent s the sending of unnecessary alarms by checking and updating unit states. Fault messages come either from hardware devices or software components. The faults ar e system or hardware specific. The Fault Diagnosis System creates upper network alarms, which are based on an analysis of the faults, and sends them to the BTS Site Manager and RNC. In addition to routing to the RNC, the alarms are buffered and, for example, active BTS alarms can be seen from the RNC. NetAct is used fo r handling the BTS alarms. The BTS is able to maintain alarm handling after it h as been commissioned and is in a configured state. During the start-up, the BTS waits for the real time clock from the Network Time Protocol (NTP) server, and t he fault diagnosis starts after the time has been set or a time-out has been det ected. If the BTS is unable to set the time using the NTP server, the default ti me (1.1.1990) will be used.

2.2

Instructions for solving problems

When starting to solve a problem, first refer to the instructions given in the i ndividual alarm descriptions. Verify the configuration of a BTS by checking the commissioning, cabling and correct installation of the units at the BTS. Make su re the environment does not cause the fault. For more information on implementat ion, normal daily operations, maintenance, and troubleshooting, refer to Nokia U ltraSite WCDMA Base Station (BTS) family, Nokia MetroSite WCDMA Base Station and Nokia MetroSite 50 WCDMA Base Station Product Documentation sets.

(10)

If an active alarm is a 'Start' alarm, a unit block/unblock (if supported by the unit) or site reset is required to cancel it. If the site reset or unit block/u nblock does not help, replace the faulty unit. See the fields 'Source of the ala rm' and 'Instructions' in the corresponding alarm description. If you cannot sol ve the problem by yourself, contact the local Help Desk.

2.3

Blocking and locking

The 'Cancel' alarms are always sent to hosts (BTS Site Manager and RNC). When th e unit or cell is in a blocked state, the 'Start' alarms are only sent to the BT S Site Manager. When a unit or cell is unblocked, all the active alarms related to the unblocked unit or cell are automatically sent to the hosts. The locked or unlocked state of a cell has no effect on sending alarms to the hosts.

2.4

Identifying faulty units

This section describes how the plug-in units are identified in different WCDMA B TS cabinets and how a faulty unit can be located with the NetAct system. See bel ow the explanations of an example 'Alarm Dialog' window for different fields in Figure NetAct Alarms window.

.

7652 *: reported severity Suppl info field: fault name Diag info field: (01) (02 ) (0A) (0010) (WFAA 04) number of the rack where the plug-in unit is located (HE X) number of the shelf where the plug-in unit is located (HEX) number of the slo t where the plug-in unit is located (HEX) not applicable faulty unit and ID .

(11)

Unit location numbers are used in alarm information to locate a failed unit. The main principle for numbering locations is from top to bottom and from the left to the right. Location numbers are defined with the following parameters: RACK S HELF SLOT Specifies the rack of the cabinet and separates BB and RF compartments from each other Specifies the shelf in the cabinet Specifies the location on th e shelf

The figures below indicate how the rack, shelf and slot are defined in different WCDMA BTS cabinets.

Difference between BTS master clock and reference frequency

Name Difference between BTS master clock and reference frequency Supreme; Optima ; Optima IBBU; Optima Compact RF Extension; MetroSite; Triplemode; MetroSite 50 WAM WSC/WMC The reference frequency that the BTS master clock receives from the transport part has changed by about 0.2 ppm or more (which equals the change mag ni tude of 204 DAC steps or more) during the measurement period (about 20 min ut es), compared to the BTS master clock frequency. The cause of the alarm can be: 1. The Iub reference frequency has changed due to a fault in the transmission ne twork synchronisation (which in turn is caused by an equipment fault or a settin g error). Note that if the network synchronisation malfunction lasts a long time , the alarm is cancelled when the BTS frequency reaches the faulty Iub synchroni sation. The alarm can also be activated if the faulty Iub synchronisation is cor rected and there is again the difference of 0.2 ppm or more. The alarm is cancel led whenever the difference becomes smaller than 0.2 ppm.

Product

(55)

2. The Iub reference frequency fluctuates continuously due to a great deal of ji tter/wander in the transmission network. The alarm is continuously activated/can celled (however, the alarming state may predominate). There is always some jitte r/wander in the transmission network; the limits are defined in ITUT G.823/824/8 25. 3. If the BTS integrated transport part receives the synchronisation informa tion via the 2.048 MHz synchronisation input (external clock source), the alarm situation may be caused by a fault of that signal. In that case, the alarm behav iour notifications listed with the Iub signal (see above) are also valid in this case. 4. There is an equipment fault in the BTS. The equipment fault is, howeve r, not the most common reason. Normally the reason can be found in the Iub/refer ence signal behaviour (see the descriptions above). Note that if the alarm 7651 BASE STATION OPERATION DEGRADED: 'WSC oven oscillator fault' becomes active, it may cause the alarm 7652 BASE STATION NOTIFICATION: 'Difference between BTS mast er clock and reference frequency' to cancel. Event type Unit status Effect Start / Cancel Degraded This fault does not immediately affect the operations of the BTS, but it is a noti fication that the BTS frequency deviates from the Iub refe rence. The BTS master clock tuning continues in spite of the alarm, but because the BTS master clock adjustment is quite slow in order to filter the instabiliti es of the Iub interface, it takes some time (even several hours) before the BTS operations start to be af fected. 7652 BASE STATION NOTIFICATION Blinking red (W SC/WMC)

Reported alarms LED display Instructions 54 (148)

(56)

Because there are several possibilities for the alarm activation, a BTS Clock Fr equency History feature has been de veloped. The stored history data can be acce ssed via the BTS Site Manager. The history data can be used as a tool for findin g out the reason for the fault/ alarm situation (for further instructions about the history feature, see the online Help of the BTS Site Manager). Depending on the possible reason, fol low the instructions below: 1. In case of fault in the transmission network synchronisation, the network synchronisation must be correc ted. The long-term accuracy of the Iub signal must be 0.015 ppm or better (check the correct Iub accuracy by measuring it). No actions on the BTS are necessaril y needed. 2. If the basic accuracy of the Iub signal is in order but there is to o much instability, that is, the jitter/wander is outside the acceptable limits, the synchronisation of the transmission network must be corrected. The limits f or the jitter/wander are defined in the ITU-T G.823/824/825. No actions on the B TS are needed. 3. In case of BTS equipment fault, the location may be: a. Transp ort part

.

First check the alarms of the AXC node with the AXC Manager and act accordingly. If there are no alarms, check the AXC synchronisation settings. If both the Iub reference signal accuracy and the AXC node are in order but the WSC unit is sti ll alarming, run the fast tuning with the BTS Site Manager. If the alarm is stil l active after the fast tuning is finished, reset the site. If that does not hel p, replace the WSC unit.

.

b. WSC unit .

. .

(57)

Note that if the reason is in the transmission network synchronisation, replacin g the WSC unit does not correct the situation. Furthermore, the alarm activity ( frequent alarms/ cancels) points to instability in the transmission network, not to a fault in the unit. 4. After the fault situation has been cleared, the BTS master clock may also require tuning because the BTS master clock adjustment is quite slow. The tuning may be done:

.

manually by changing the DAC word (during a site visit) or with fast tuning, in which the BTS master clock is tuned in a few minutes automatically near the Iub reference (normal tuning takes care of the fine tuning). Note, however, that the fast tuning should only be used in case the Iub reference signal is known as a good one. Otherwise the BTS frequency may be tuned into a totally incorrect valu e, causing serious problems in the network performance.

.

Background information: The principle is that in the mobile network, the synchro nisation goes from MSC => RNC => BTS. But in reality that chain might be broken somewhere and, for example, when using leased lines, the BTS may take the refere nce synchronisation from the transmission network of another operator. This does not harm the system if the synchronisation of the leased line service provider is also accurate/stabile enough. The BTS uses the incoming synchronisation signa l as a reference for the Air interface, the accuracy requirement of which is set by 3GPP.
