Telecommunications tariffs
Encyclopedia
A telecommunications tariff is an open contract between a telecommunications service provider and the public, filed with a regulating body such as a Public Utilities Commission

. Such tariffs outline the terms and conditions of providing telecommunications service to the public including rates, fees, and charges.

Why are tariffs charged?

At a minimum, tariffs imposed must cover the cost of providing the service to the consumer. The consumer may be the final user or an intermediary such as a service provider

 and other indirect costs associated with providing the service. However, telecommunications service providers must be careful not to over-price each service, as prices have a direct influence on demand for that service (see supply and demand

It concludes that in a competitive market, the unit price for a particular good will vary until it settles at a point where the quantity demanded by consumers will equal the quantity supplied by producers , resulting in an...

If an operator charges too much, it risks alienating its customers, resulting in a loss of traffic and therefore revenue; if they charge too little, they will have insufficient capital to maintain the network's Quality of Service

Components of tariffs

Tariffing systems vary from country to country and company to company, but in general they are based on several simple principles. Tariffs are generally made up of two components:
  • Standing charges: these are fixed charges that are used to pay for the cost of the connection to the nearest exchange and the equipment to monitor that customer's phone line or service connection. They are usually paid on a monthly basis, and called rental.
  • Call charges: these charges are variable and are used to pay for the cost of the equipment to route a call from the caller's exchange to the recipient's exchange. These call charges can be calculated on a fixed per call basis, a variable basis depending on the time or distance of the call, or a combination of the two. Call charges can even vary at different times of the day. For many local calls the charge is zero; see flat rate
    Flat rate
    A flat fee, also referred to as a flat rate or a linear rate, refers to a pricing structure that charges a single fixed fee for a service, regardless of usage. Rarely, it may refer to a rate that does not vary with usage or time of use...

    .


These components form a basic tariff system but there are much more complex versions in existence too. For example, there is generally a connection fee to connect a new user to the network

 known as reversing charges), where responsibility for charges normally paid by the caller is accepted by the recipient.

Tariffs also depend on the bandwidth provided. For example, dial-up modem

Special tariffs

Increasingly, in some countries, the call charges are fixed at a monthly rate and included as a supplement to the standing charges, known as inclusive calls.

Most countries have a number sequence that enable the caller to make calls without charge, sometimes known as free calls or freephone, these are usually used by companies for their sales line (in the UK these are 0800 and 0808 numbers).

Tariffs substantially in excess of the normal rate, known as premium rate

Impact of tariffs on traffic

Call minutes are highly elastic against price

, this means that the demand for call minutes varies greatly according to price. A slight decrease in price leads to a great increase in call minutes. The higher the price, the more this effect is noticeable, for both business and residential customers on international or local calls. This means that it is often the case that more revenue is achievable at lower prices, that is, E < -1.

Internet traffic research show that the traffic intensity is directly affected by the tariffs charged in connecting customers to their Internet Service Provider

 (ISP). For example, a circuit-switched network provider charges different tariffs at different times of the day. It was noted that at the time that the rates decreased, the traffic intensity logged by the ISP increased dramatically and then decayed over time at an exponential rate. The conclusion of the research was that by varying prices over time, a telecommunications service provider can reduce the level of the traffic intensity at peak periods, resulting in lower equipment costs because of the reduced need to provision to meet peak demand, which in turn leads to increases in long-term revenue and profitability.

Time-based pricing

The rational background of time-based pricing is expected or observed change of the supply...
