Now to signaling and delays. The issue of delay has been in our system since the beginning of our operations in Nepal since MeroMobile times. The case get’s active every now and then and I also got interested in the technical logic of it. Our guys checked other operator call data too, their delay is also about 2 seconds which is natural cause they have same vendor as us, ZTE. Other operator do not sent end call notification, so our approach is very transparent and visible to everyone to see. The signal actually goes back and forth between handset and MSC (Mobile Switching Center) and MSC sends a “timestamp” to billing system to register the call to be charged. The standard 3GPP (http://en.wikipedia.org/wiki/3gpp) delay in this signaling is 1 second according to ZTE. We also checked our other vendors like Ericsson and the delay is the same in Azercell and Kcell. Why then 2-3 seconds? You remember old days when timing was made for 100 meters run: there was six guys sitting with a watch and some got 10,2 and some 10,6 seconds for the same. And world records was calculated on average base. Same thing here. We also checked differences with phones: if you use a phone with more sophisticated processor, the delay is less. And last but not least, because of rounding. 10,1 seconds is rounded to 11 which again is a business practice.

Naturally the signaling is only one part of how the “piano plays”. Ncell is always generous in tariffs, we just gave Every Second MINUTE free…well might been every 58 second slot free if someone wants to be very specific. But naturally we consider different tariff schemes according your proposals.

Weekend Ramaailo Garnus!
