Procedures

Augere Pakistan

1) Note down the details from the field engineer2) Details are: Username, GPS Lat/Long,

Vendor, CPE type and model, Antenna type, BTS id, MAC, Height and Engineer Name.

3) Note down these details either on a writing pad or on PC using Notepad application and give time to call back for confirmation (10-15 Min)

4) Create the “Subscriber Information Trace” and observe the parameters.

5) In case of RF parameters are not according to KPIs or error packets on uplink are continuous then suggest for repointing in case of HG antenna.

M2000

• M2000 is the proprietary network monitoring system which works on client-Server architecture.• M2000 provides management functionality and other configurations of the entire network (BTS and ASN Gateway)• It also facilitate CPE (MS in M2000) related information in the form of traces.• There are two commands which are used to get the subscriber information : 1) DSP MSINFO and 2) DSP MSONLINEINFO• Subscriber live traces can be create from “Trace Collection Management” found under the tab “Monitor”.• Refer to the diagrams

Entity Selection for DSP MSINFO

Augere Pakistan

You can select either a BTS to run a command or ASN (But New ASN does not support this function from M2000 directly )(This option is now unavailable in New version of ASN)

* DBS3900 is the Huawei BTS name

Running the Command On BTS

To run DSP MSINFO command you need to select a BTS this show the RF stats of an instant. You can run the DSPMSONINEINFO by selecting multiple BTS by putting check. To search a CPE on entire Network you can run DSPMSINFO on all BTS if you are unaware of CPE

Live Subscriber Trace

Advantages- Real-time physical layer statistics- More information in contrast to DSPMSINFO command- Uplink Errors and abnormal power adjustments can be observed- Reliable way for observation of a CPE

Disadvantages- Time consuming- More parameters are required to be known

Creating a Live Subscriber Trace

Select this option to open trace interface

This is the main window of Trace Management

Augere Pakistan

Select the BTS

Give a desired name

Double click this to open this window

Uncheck start and end time so that tracing start immediately. (Optional) If you are putting start time then you need to run the trace by R-clicking on trace and select run.

Now insert the MAC ID of the CPE and set the “Report period to “1” the units are in Second”

After pressing Finish button the trace will show on main window with “Running” status in case of any error it will have “initialize” status. You can recreate the same trace by coping it and put different BTS or MAC.

Normal Traces

Ping Response

Erroneous Traces

Augere Pakistan

This field is showing uplink error packets count

This is showing frequent power adjustments which is due to uplink interference

Ping Response

Outdoor CPEs are having wider beamwidth and TX power.

Misaligned CPEs causes disturbance in the same frequency sectors of other BTS

Results in----- > BadPackets/Outerloop (power Adjustments)

Causes problems in Urban Areas(Note: No interference within the same sector. Y? OFDM)

Uplink Interference Causes

Proper alignment of CPEs even in case of HG antannas.

Minimize the Outdoor CPEs from the Network as coverage become good.

Minimum possible height Downtilt

How to avoid this?

Our KPIs

CPE Model CINR RSSI MCS

Siemens >14dB > -80dBm QPSK 1/2

Indoor HGA > 16dB >-85dBm 16 Qam

Outdoor CPE >20dB -65dBm to – 80dBm

16QAM or 64 QAM

Zyxel CPE >14dB > -80dBm QPSK 1/2

Criteria for Outdoor CPEIf Location meets the following conditions:

-Distance from BTS is more than 1km (Within 600m Strictly not allowed).

-RSSI < -55

-CINR values are not too HIGH (28dB, 30dB etc).

-Height is not too High that I could potentially interfere other Sectors.- Coordinates

Known Issues Faced by Teams

Uplink Interference: Solution is Reposition the CPE or HG by reducing height

Augere Pakistan

Authentication Issues: Possible reasons are :1) Username/Password is wrong 2) The insufficient balance.

In case of about mentioned problem ask team to refer to call center for a password Reset or contact distributor if balance is insufficient in the subscriber account

IP Stuck: RF stats are very good but not internet service. This problem can be Solved by kicking the CPE form the network .
