Zone Points (Telecommunication Charging part 1)

Now, I would to share a little about CHARGING in Telecommunication

Call change are generally calculated on the basis of the distance between the calling and called parties and in dependence upon the network provider (carrier). In other words, a local call can be lest expensive than a long-distance call because it uses fewer network resources. Also, two calls, for example, made from the same terminal to the same destination may incur defferent carrier are used.

     

     * Note : Telephone network with  six zones and 4 carrier

       Thus, there are separate zones for :

                                  - Local calls

                                  - Long-distance calls

                                  - International calls

                                  - Intercontinental calls

Each is governed by a uniform call-change policy, comprising the currently valid tariffs and the times set for tariff swithovers(from daytime to night-time tariff, etc). The tariff for these zones must be entered before the zone points are created. In call processing, the zone is identified by the digit-zone translator by interpreting the dialed digits.

The Translator must perform the following function on the basis of predefined digit combinations, line codes(e.g. category and origin), the transmission quality and – if applicable – the carrier: 

                         

                              -Identify zone destination point :

                   o   Home exchange

                   o   Long distance exchange

                   o   No exchange(i.e. zone point not created

                 -Zone destination point = home exchange :

                   o   Provide zone(1-126, 128-254, 256-511) 

That All about my post. Don't worry, I'll write the next part soon ..
Thanks..
