Paging Dimensioning •

There are 5 TMSI per TTI (10 ms), with assume that concurrent user for paging is maximum 5, that means only have 5 kanal in one time that can be use simultanesly. So, with erlang Table5 channel GoS 1% is around 1,36 Erlang, maksimum occupancy = 1.36 / 5 = 27.22 % For hurly, that meant if occupancy can reach 100%, the attempt is 3600 s *5 TMSI / 10 ms = 3600*5*1000/10 = 1.800.000 per hour 27.22% * 1.800.000 is 500.000 paging per hour

Site Cell Suggestion Number Number Paging attempt reach 2000k/hour, PCH Congestion rate reach 318 1295 26%, propose to split to 4 LAC PCH attempt reach 600k/hour, PCH Congestion rate reach 133 622 1%, suggest to split to 2 LAC PCH attempt reach 1400k/hour, PCH Congestion rate reach 222 999 10%, suggest to split to 3 LAC PCH attempt reach 1100k/hour, PCH Congestion rate reach 200 1013 5%, suggest to split to 3 LAC PCH attempt reach 800k/hour, PCH Congestion rate reach 179 888 1.6%, suggest to split to 2 LAC PCH attempt reach 1800k/hour, PCH Congestion rate reach 133 622 3.4%, suggest to split to 2 LAC PCH attempt reach 1600k/hour, PCH Congestion rate reach 324 1429 18%, suggest to split to 4 LAC PCH attempt reach 500k/hour, PCH Congestion rate reach 283 1088 0.9%, suggest to split to 2 LAC PCH attempt reach 600k/hour, PCH Congestion rate reach 224 874 0.8%, suggest to split to 2 LAC PCH attempt reach 1600k/hour, PCH Congestion rate reach 320 1387 18%, suggest to split to 4 LAC PCH attempt reach 200k/hour, PCH Congestion rate reach 173 628 0.14%, do not need LAC split

The LAC split should be consider if the paging congestion greater than 1% or paging attempt greater than 500k/hour

Why Paging Utilization= 1 % b. When VS.RANAP.CsPaging.Att > 300 K -> LAC SPLITTING c. Others -> RAC SPLITTING 1. For Multiple RAC  – LAC Case in RNC a. When Paging Attempt LAC-RAC > 500 K & Paging Congestion >= 1 % b. when Paging PS Portion in LAC-RAC < 40% -> LAC Splitting c. Others -> RAC Splitting
