Let's start with the principles and history of fees。
The old method of charging charges is to call and receive local numbers locally, receive local calls locally, call local calls locally, charge local calls locally + long-distance calls, take off off-site calls, and, with the exception of the special case of cruise calls with the same city, to collect cruise calls + long-distance calls, to call off-site local roaming calls, to make off-site calls elsewhere, to collect cruise calls + long-distance calls。
There's a logic, or technical reason, to charge this fee。
Ab is a beijing mobile user, b goes to shanghai, a calls b in beijing. This is a long-distance call. Who's paying for the long-distance bill? He couldn't find a, and he didn't know if b was in beijing. He had to find b。
If the mobile user c in shanghai at this time calls b, which is a beijing number, b and c are in a network, and c now discovers that b will be connected directly after shanghai, this call is not a long-distance call, called "a special case in the same city" and the call c is not a long-distance call。
If this is the time when shanghai telecom's user d calls b, not a network, shanghai telecom does not know b is in shanghai, so it will be transferred to beijing, which will then be connected to shanghai's user b. So wherever b is, d calls him long distances。
It sounds complicated and brutal, but it's not far from it。
In the middle ages, mobile phone subscribers skyrocketed, prepaid, moving and connecting to a global system that pays monthly rents or other fees. World wind users reduced the local call fee from 0. 6 to 0. 4, but the non-fixed prepaid payer was 0. 6, the earliest differentiated fee。
And then it's coming into the modern age。
In 2008, the government issued a document, " two sectors noticed reduction of the minimum domestic rover telephone fees for mobile phones " :
“simplify the roaming fee structure by combining domestic roaming calls and domestic long-distance calls in a roaming state; do not distinguish between late payment and prepaid charges; and domestic roaming calls are capped for differential pricing。
Domestic mobile phone roaming charges have been reduced to a ceiling of 0. 6 per minute and 0. 4 per minute. The use of domestic long-distance circuits is no longer subject to additional domestic long-distance calls.”
In 2009, the government issued an additional document, the circular of the ministry of industry and information technology of the national development and reform commission on simplified mobile phone billing:
“the current charge for both local and long-distance calls is combined into a charge for “long-distance calls” when mobile phones are dialed locally。
Mobile phones are charged only for international and long-distance calls under domestic roaming conditions and are no longer charged at the same time as domestic roamers.”
The two documents have changed significantly in the form of fees. In the middle of this, there was a quiet occurrence of one-way charges, which, although locally called free, had changed considerably. This time, the market was done spontaneously, the government had no intention of saying anything, then entering modern times, when china entered the age of 3g, and the country was free of charge, and the main call was a local free-rider and long-distance package, with the threshold of such a set falling and the unit price falling。
