Discrepancies

B5

Brandon: No. of measurement periods, after a call has been established on a TCH, before the full set of measurements shall be used.

B6

Brandon: Desired initial SS measured by the receiver in the BTS

B7

Brandon: Length of the initial SS filter. Recommended: INILEN < SSLEN

B8

Brandon: Power Margin - used on the new channel at assignment of a TCH, on the old channel at assignment failure or HO failure, and on the new channel at intracell HO and subcell change.

B9

Brandon: How much of the path loss that shall be compensated for

B10

Brandon: The weight of the quality compensation

B11

Brandon: Desired quality level measured by the receiver in the BTS

B12

Brandon: Length of the quality filter

B13

Brandon: Desired signal strength at the outerrim of the regulation area

B14

Brandon: Length of the stationary signal strength filter

B15

Brandon: Minimum time period between two consecutive power orders

B20

Brandon: Target value for desired SS measured by receiver in the MS at outer rim of the regulation area

B21

Brandon: Target value for desired quality measured by receiver in MS (transformed into dB units before used in algorithm)

B22

Brandon: How much path loss that shall be compensated for in the algorithm that regulates towards quality

B23

Brandon: Determines the weight of the quality compensation

B24

Brandon: Defines the regulation interval

B25

Brandon: Defines the length of the frequency plan filter

B26

Brandon: Defines the length of the quality filter

B27

Brandon: Switch for the regulation of SDCCH channels

B28

Brandon: Defines the minimum allowed output power for the BTS on the non-BCCH frequencies

B29

Brandon: ratio between the up and down regulation speed
