Hi

Hi All

All Need your suggestions for the Topics to be discussed for the next week.

For Fresher : We are going to Start basic concept blog everyday.Please go through it.

For others : we are covering now 2G Planning and Optimization first
after it, we will start CDMA Planning and Optimization and then 3G Planning and Optimization with parameter tunning.


Meanwhile We need your suggestions to make it better.

1. What is the function of SDCCH & SACCH?

Ans. (a) SDCCH---- Slow Dedicated Control Channel.

Function----

a) Location updates

b) SMS

c) Ciphering Initiation

d) Equipment Validation

e) Subscriber authentation

f) Call set up signaling

(b) SACCH---Slow Associated Control Channel.

Function:

(a) Timing advance data

(b) Transmit power control

(c) transmission of signaling data

(d) radio link supervision measurements

2. What are the reasons for Hand Overs?

(Ans) . (a) Signal Strength (RX LEVEL)

(b) Signal Quality (RX Qual)

(c) Power Budget

(d)Timing Advance.

(e) Interference

3. What are the shortcomings in handovers?

a) Call Dropping.

b) Ping- Pong handover

c) Far- Away cell effect

4. What is intelligent hand over?

(Ans)

a) Fuzzy logic

b) Neutral networks

5. What are internal & external hand over?

Ans

(1)INTERNAL HANDOVER

a) ( INTER BTS) ---- Transfer between two channels (time slot) in same cell.

b) ( INTRA BSC ( BTS –BTS)-----1 . transfer between BTS under control of same Bsc

2 Measuring the quality of radio connection

3 Power levels

2. EXTERNAL HANDOVER.

( a) INTER BSC (BSC_ BSC)---- 1. Transfer between BTS under

the control of diff BSC

2. BSC TO BSC

3 . NSS to attends the hand over

4. MSC controls.

( b) INTER MSC ( MSC- MSC) ----1. transfer between cell under the control of diff MSC

6.What is the frequency Hopping its imp?

(Ans)

· It is defined as sequential change of carrier frequency on the radio link between mobile & base station.

· Two types of freq hopping----- 1. Base band freq hopping.

2. synthesized frequency hopping.

7. Explain the major diff between BBH & SFH?

Ans

· In BBH the no of hopping freq is same as no of TRX.

· In SFH the no of Hoping freq can be in the range of 1to 63.

8. what are the advantages of Frequency Hopping?

1. Frequency Diversity
2. Interference Averaging
3. capacity

9. How in frequency hopping there is enhancement of network capacity?

· Freq hopping implement will enable more aggressive freq reuse pattern, that leads to better spectrum efficiency.

· It can add more transceiver in the existing sites , while maintaing the net work quality/

· Freq hopping compressing the available spectrum to make room for extra capacity

.

10. Define the freq. hopping parameters?

Frequency Hopping Parameters

GSM defines the following set of parameters:

Mobile Allocation (MA): Set of frequencies the mobile is allowed to hop over. Maximum of 63 frequencies can be defined in the MA list.

Hopping Sequence Number (HSN): Determines the hopping order used in the cell. It is possible to assign 64 different HSNs. Setting HSN = 0 provides cyclic hopping sequence and HSN = 1 to 63 provide various pseudo-random hopping sequences.

Mobile Allocation Index Offset (MAIO): Determines inside the hopping sequence, which frequency the mobile starts do transmit on. The value of MAIO ranges between 0 to (N-1) where N is the number of frequencies defined in the MA list. Presently MAIO is set on per carrier basis.

Motorola has defined an additional parameter, FHI.

Hopping Indicator (FHI): Defines a hopping system, made up by an associated set of frequencies (MA) to hop over and sequence of hopping (HSN). The value of FHI varies between 0 to 3. It is possible to define all 4 FHIs in a single cell.

Motorola system allows to define the hopping system on a per timeslot basis. So different hopping configurations are allowed for different timeslots. This is very useful for interference averaging and to randomize the distribution of errors.

11. What are the effects of freq hopping?

(Ans)

1 Handovers:

2 Call setup:

3 Frame Erasure Rate (FER):

12 .Explain in brief what is FER.

• Ans FER= Number of erased blocks\ total no of blocks *100
• It is the right measure of voice quality.
• FER is performed on speech& signaling frames
• FER------- 0 to 4%, GOOD.

4 to 15% , slightly degraded

Greater than 15%, useless

13. What happens when speech frames discarded in FER?

· System will interpolate.

14. What happens when signaling frames discarded in FER?

· MS is instructed to resend.

15. What is TCH_ TCH Interference? How it is measured.

· When TCH carries are reused that leads to co-channel interference.

· When TCH carrier have call activity.

· This is measured by delta measurement. --- 1. BCCH carries are diff

2. TCH carriers in both cell 1& cell2 are same AFRCN TCH

16. Define the terms?

· BER--- The number of erroneous bits received

Total no of bits received.

· RBER---1 Residual bit error rate

2 It is performed on demodulated speech frames that are not mark corrupt

.

· BFI -- Bad frame indication.
