PCH : p *782 bit/s (GSM 05.01)
combined BCCH: (p=2) : 1564 bit/sec throughput on air interface
“paging request” message = 22 octets = 176 bit
==> 8,9 paging messages per second
32000 messages/ hr
1 .. 4 MS can be paged per paging message
depends on paging method used and statistics
take 1,5 MS per message as average
approx. 48000 paging events per hour
paging load depends on call statistics and
size of location area

Average subscriber has 90 sec air-time in Busy Hour,
1/3 thereof are terminating calls
average call duration: 120 sec
2 pagings per call (network parameter)
==> ~30 sec MTC = 0,25 call ==> 0,5 paging/hr/sub needed
Approx. 96000 subs per location area
location area ~ 80 ...120 cells
Approx. 800 ... 1200 subs per cell
average subscriber = 20 mErl traffic load
==> 16 .. 24 Erl/cell ==> 4 TRX/cell should be o.k.
