Number of reserved access grant blocks. Number of CCCH blocks reserved for the
access grant channel. The remaining CCCH blocks are used for the paging channel.

Multiframes period. Defines period of transmission for PAGING REQUEST messages
to the same paging subgroup. (Please refer to table MFRMS)
AGBLK : 1 ; 8 CCCH blocks in each multi frames and possible to have 16 to 72 Paging Group
A high number of paging groups means that the mobiles have to wait for a longer time than the low
number case before the right paging block arrives. This increases the time for paging. It also
reduces the paging capacity compared to using fewer paging groups. This is because with a high
number of paging groups, each paging group will have a short paging queue in the BTS.

Defines period of transmission for PAGING REQUEST messages to the same paging subgroup. (Please refer to table MFRMS) AGBLK : 1 ; 8 CCCH blocks in each multi frames and possible to have 16 to 72 Paging Group A high number of paging groups means that the mobiles have to wait for a longer time than the low number case before the right paging block arrives. This increases the time for paging. It also reduces the paging capacity compared to using fewer paging groups. This is because with a high number of paging groups, each paging group will have a short paging queue in the BTS.

HYSTSEP takes a positive value that represents the corresponding negative value in calculations. Note: HYSTSEP is only valid for the Ericsson3 locating algorithm. MICROCELL STREETCELL INDOOR OFFSET -63 TO 63 GSM1800 (MACRO) d B 0 0 Signal strength offset. The parameter is represented by OFFSETN, if the value is in the range (−63, -1) dB. Positive values, (0, 63) dB, is represented by OFFSETP. Note: OFFSET is only valid for the Ericsson3 locating algorithm. MICROCELL STREETCELL 0 INDOOR 0 Locating (ericsson3)
