互联网络费
参考段落：
Network interconnection is big business.BT,for example,received [pound]2.8 bn ([euro]3.08 bn) from other operators in the UK in its financial year ending March 2001.This represents 15 per cent of BT's total income.And as BT's interconnect rates are amongst the lowest in Europe,this percentage is even higher for many other incumbents.For carriers (operators that carry calls for other operators as their main business) interconnect revenue will represent their largest source of income.
