Traffic that proceeds by telecommunication network, in one-day full operation, will have variation density. Switching equipment plans and network invented based on traffic estimation on busy hour.
Outer busy hour, for the greater part of equipment that available in the network is usually in idle condition.
In order to traffic variation density can distributed flatten, telecommunication services provider usually applied variation charging on a certain hours in one day. So the costumer can choose the right time to call.
This charging variation method, generally with speedup or slowdown duration per meter pulse, even though pulse cost is constant. Seed up time duration between pulse usually do on busy hour, so that costumer that call on that time the pulse meter will move quickly from the standard time, and for call time duration that is same will charge with a high charge then if that conversation performed in another time that speed between pulse is not accelerate. With this method hopingly un-important conversation can postpone, performed in outer busy hour.
Delayed time duration between pulse usually performed on outer busy hour, example night, dawn, or weekend, so that costumer who call in that time the pulse meter will move slower then the standard time, and for call time duration will charge lower then if that conversation performed in another time that speed between pulsed not slow down.
This charge variation is usually only for local connection type or trunk, is not for international connection. Speed variation between pulse that confirmed, between telecommunication services operator or inter country usually also different, in spite of generally model that a lots used is such as that showed on table 4.1.
Day period Rate between meter pulse
06.00 – 18.00 T
18.00 – 21.00 3/4T
21.00 – 24.00 1/2 T
00.00 – 06.00 1/4T
Table 4.1 Generally charge variation model (only as sample)
For long distance connection, besides formed by time call, charge variation also formed by distance between caller and who called. The longer a distance, shorter duration between pulses. Limits distance it self usually already formed clearly by local telecommunication services provider.
