Air interface paging dimensioning for 2G The Air interface capacity in terms of paging attempts is related to several parameters such as BCCH combined mode or not and the number of AGCH Blocks in the CCCH, here after the results for some examples. Combined mode CCCH | 2 PCH, 1 AGCH | 2 | Not combined mode (2 AGCH) | 9 CCCH (7 PCH and 2 AGCH) | 7 | Not combined mode (1 AGCH) | 9 CCCH (8 PCH and 1 AGCH) | 8 | paging per PCH | | 3 | needed paging per mobile busy hour | | 2 | Frame (s) | 51 TDMA | 0.235 | MAX LAC load per hour | Combined mode CCCH | 45957 | | Not combined mode (2 AGCH) | 160851 | | Not combined mode (1 AGCH) | 183830 | |
