For those who know the telephone traffic theory, these daily ,
changing charging plans are nothing but mere gimmics of
the service providers to somehow enhance market share by
hoodwinking the public instead of really bringing down the cost.
The average talk time is about 150 seconds. At 1 paisa per second
the average cost of a local call will be 150 paise.
Compare this with the Per Minute Charging at 50 paise per minute charging plan.
In the universally accepted charging method according to Carlson's revised
charging plan, the call charge will be:-
Answer fee + ( Talk time / periodic charging duration, the end fraction ignored)
= 50 paise + 2 x 50 paise = 150 paise. So neither the Service Provider loose
anything nor the customer gain much.
However, compare this with the local call charge in a wired line net work which
is only Re. 1 per 3 minutes talk time.
According to standard method of charging, a local call of upto 180 seconds in the
fixed line network will be only Re. 1 whereas this will Re. 1.50 on an average
in a mobile network with one paise per second charging.
The cost of the end link in a wired line network being much higher than the wireless
connectivity in the Mobile system, the cost of Mobile call is still much high in local call
which will be about 65 percent of the total outgoing call from any phone.
The higher call charge in Mobile communication is justifiable for the mobility factor.
However, as the Mobile phone percentage becoming predominent, the mobile call
charge has scope for further reduction making it equal to land line call charge.
It would be wise for the regulator and the service providers to stick to standard
charging methods without confusing the users with umpteen charging plans.
Ultimately, the Service Provider that can offer good quality service across the
country will be the winner. Many of these companies indulging in so called
price wars do not qualify to that level.
