- 20. GSM Neighbors This windowis very helpful in case of 2G – 3G Handovers as we can see all the 2G neighbors of that particular 3G cell in the compressed mode state.
- 21. Serving/Active Set +Neighbors Cell I.D – This is the identity or name given to a particular Node B and its cell by the operator. UARFCN – It is the frequency band allotted to the operator. One spectrum bandwidth is of 5MHz in WCDMA or 3G.This window shows us the centre frequency of the bandwidth allotted to the operator.
- 22. Serving/Active Set +Neighbors Cell Name – It is the name given to particular Node B’s by the operator generally along the lines of the name of the area the Node B is located in. Scrambling Code – Scrambling code is a code assigned to a particular cell. There are 512 such codes for the network to differentiate among different Node B’s and these codes can be repetitive. They are of two types primary and secondary.
- 23. Serving/Active Set +Neighbors AS – This stands for Active Set. Active Set is the set of Scrambling Code which the U.E is currently latched on and there can be a maximum of 3 Scrambling codes in Active Set. MN – MN Stands for monitored neighbor i.e. the neighbor cell that is detected by the U.E as a neighbor and is also defined as a neighbor in the network. U.E will initiate a Handover onto the monitored neighbor in case the monitored neighbor has a stronger RSCP or EcNo than the AS.
- 24. Serving/Active Set +Neighbors DN - DN stands for Detected Neighbor and as the name suggests it is the neighbor detected by the UE but, is not defined in our network . Hence, the U.E does not handover to the detected neighbor. It can be because of Overshooting of a site, incomplete neighbor list or in case of a new site. It is very important to optimize and have no DN’s as they are one of the major reasons of Call drops in 3G.
- 25. Radio Parameters CPICHEc/No – Common Pilot channel Ec/No is the ratio of energy of the chip and the combined power of all the signals including the pilot itself received by the UE at that particular point. It is a very important factor for call quality. CPICH RSCP – Received Signal Code Power is the level of the signal received by the U.E from a particular pilot.
- 26. Radio Parameters Radio parametersare the parameters of a Mobile equipment – Tx Power – As the name suggests it is the transmitting power of a Mobile Station. Its value can vary from -50 to 50. The minimum the Tx power of the Mobile station the better it is for call quality. UTRA Carrier RSSI - It is the Received Signal Strength Indicator of the Mobile Station or the U.E. It tells us the total Power Received by the Mobile Station from all the Pilots including itself at that particular location.
- 27. Radio Parameters SIR– It is the signal to interference Ratio is the ratio of Energy in the DPCC(Dedicated Physical Control Channel) to that of the interference and noise received by the U.E. Target SIR – It is the target Signal to Interference ratio that Mobile Equipment is supposed to achieve by increasing or decreasing its power. It is set by the use of Power Control procedure.
- 28. Radio Parameters SQI- It is the speech Quality Index which is a parameter to rate the voice Quality on that particular call. It ranges from 0 – 30 with 30 being the best quality. RRC State – It tells the current state and channel as in Idle or dedicated. Mode – It is the mode that we are using GSM or WCDMA.
- 29. HSPA/GSM Line Chart This window gives us the data speed for both 3G and 2G modes depending on which mode the mobile equipment is. RLC DL Throughput – This is the total throughput on the downlink at that particular point. The speed shown in this window as throughput is in Kilobits/sec.
