The Telecom Regulatory Authority of India on Thursday indicated that the existing tariffs of all types of services, be it basic or cellular, may come down with the introduction of the new Interconnect User Charge regime.

"The revised Access Deficit Charge regime will impose a lower overall burden due to lower overall access deficit and thus will allow competition in market to sustain and even to leave scope to reduce the prevailing tariff levels in all services," TRAI said in a statement.

According to TRAI, the principles for new IUC -- charges paid by operators for using other's network -- have been finalised and the same would be notified in the third week of October.
