1. Channel Element concept

The "channel Element" is the minimum base band resource to support a UMTS (3G) service.

2. NodeB/RNC ULCE and DLCE license.

The current resource ULCE and DLCE configuration can be downloaded from the M2000 using the following commands:

a) With the option “performance” and “query result” using the counters

b) With the option mml command using the command:

“DSP LICENSE”

c) With the option

3. ULCE and DLCE hardware capacity.

The capacity depends on the sort of WBBP Board installed in the nodeB.

WBBP_Board_descrition

The current resource ULCE and DLCE hardware capacity can be downloaded from the M2000 using the following commands:

a) With the option “performance” and “query result” using the counters

b) With “mml command” using:

“LST BRD” and “LST BRDINFO”

4. Channel Element Utilization

The utilization of the channel element resources in uplink and downlink is provided by the counters:

5. Channel Element Congestion

The congestion of the channel element resources in uplink and downlink is provided by the counters:

CRITERIA FOR INCREASE CE LICENSES

Criteria for increase.

Three consecutive days with (Occupancy > 70%) Or (Congestion > 0.2%).

Once the criteria is met (any of the two conditions), then apply the following formula in order to increase number of licenses in steps of 16, setting the node to an occupancy of 40% using the current occupancy and current number of licenses.

Where:#_Current_CE =Current number of Channel elements

%_Occupancy=Percentage of occupation corresponding of days calculated.

ROUND_UP_MULT_16= Is the meaning of round in multiples of 16.

This criteria must to be used for UL and DL

Uplink and Downlink must to be handled separately.

The way to calculate the OCCUPANCY and CONGESTION by War-Room is described in following slides.

CRITERIA FOR DECREASE CE LICENSES

Criteria for decrease.

Three consecutive weeks with (Occupancy < 20%) AND (Congestion = 0%) AND

(Current number of CE_UL > 128) For calculation in uplink or

(Current number of CE_DL > 64) For calculation in downlink.

Once the criteria is met (the three conditions), then apply the following formula in order to decrease number of licenses in steps of 16, setting the node to an occupancy of 50% using the current occupancy and current number of licenses.

Where:#_Current_CE =Current number of Channel elements

%_Occupancy=Percentage of occupation corresponding of days calculated.

ROUND_MULT_16= Is the meaning of round in multiples of 16.

= ROUND_MULT_16 #_Current_CE UL - MAX (No_Current_CE UL * %_Occupancy)# CE_UL to decreasing 0.5

= ROUND_MULT_16 #_Current_CE DL - MAX (No_Current_CE DL * %_Occupancy)# CE_DL to decreasing 0.5

OCCUPANCY CALCULATION BY WAR-ROOM

Current(VS.LC.ULCreditAvailable.Shared)

Max_per_day (VS.LC.ULMax.LicenseGroup.Shared) DAY 1

Max_per_day (VS.LC.ULMax.LicenseGroup.Shared) DAY 2

Max_per_day (VS.LC.ULMax.LicenseGroup.Shared) DAY 3...

Average

OCCUPANCY =

Occupancy = The average of the maximum per day of VS.LC.ULMax.LicenseGroup.Shared counter divided by current number of CE (VS.LC.ULCreditAvailable.Shared).

CONGESTION CALCULATION BY WAR-ROOM

SUM(VS.RAB.AttEstabCS.Conv+VS.RAB.AttEstabCS.Str+VS.RAB.AttEstabPS.Conv+ VS.RAB.AttEstabPS.Str+VS.RAB.AttEstabPS.Int+VS.RAB.AttEstabPS.Bkg)

SUM (VS.RAB.FailEstabCS.DLCE.Cong+ VS.RAB.FailEstabPS.DLCE.Cong)

CONGESTION =

Congestion =The sum of PS & CS RAB Fails divided by PS & CS RAB Attempts.

This formula will be used for UL & DL, only change counters in numerator.
