Prepaid Telephone Call
Prepaid telephone calls are a popular way of making telephone calls which allow the caller to control spending without making a commitment with the telephone company. Prepaid phone cards are provided by various telecom companies. When you purchase a prepaid phone card, you are paying for long distance connection time in advance. When you make calls using the phone card, the card's value is deducted based on connection fee, duration of connection, surcharges and any maintenance charges associated with the phone card. Prepaid telephone calls are usually implemented in the company's network using the intelligent network functionality. The competitive prices these operators offer are usually made possible by least cost routing and lower overheads than the larger telephone operators. Types of prepaid calling * Telephone prepaid calling cards (commonly known as Phone Cards in the US and the UK) are available from newsstands and drugstores. They are often the cheapest means of making ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Telephone Call
A telephone call, phone call, voice call, or simply a call, is the effective use of a connection over a telephone network between the calling party and the called party. Telephone calls are the form of human communication that was first enabled by the development of the telephone and several inventions in the mid- to late-19th century. Initial technology involved point-to-point electrical wire connections between telephone installations, until centralized exchanges evolved where Switchboard operator, telephone operators established each interconnection manually at a telephone switchboard after asking the calling party for their call destination. After the invention of automatic telephone exchanges in the 1890s, the process became increasingly automated, eventually leading to the widespread adoption of digital exchanges in the second half of the 20th century, including the transition to wireless communication via mobile telephone networks and cellular networks. With the developm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
PSTN
The public switched telephone network (PSTN) is the aggregate of the world's telephone networks that are operated by national, regional, or local telephony operators. It provides infrastructure and services for public telephony. The PSTN consists of telephone lines, fiber-optic cables, microwave transmission links, cellular networks, communications satellites, and undersea telephone cables interconnected by switching centers, such as central offices, network tandems, and international gateways, which allow telephone users to communicate with each other. Originally a network of fixed-line analog telephone systems, the PSTN is now predominantly digital in its core network and includes terrestrial cellular, satellite, and landline systems. These interconnected networks enable global communication, allowing calls to be made to and from nearly any telephone worldwide. Many of these networks are progressively transitioning to Internet Protocol to carry their telephony tra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prepayment For Service
Prepaid refers to goods and services paid for in advance. Examples include postage stamps, attorneys, tolls, public transit cards like the Greater London Oyster card, pay as you go cell phones, and stored-value cards such as gift cards and preloaded credit cards. Prepaid services and goods are sometimes targeted to marginal customers by retailers. Unlike postpaid or contract based services, prepaid accounts can be obtained with cash. As a result, they can be established by people who have minimal identification or poor credit ratings. Minors, immigrants, students, defaulters, and those on low incomes are typical prepaid customers. In accounting terms, a prepayment is treated as an asset by a buyer, and as a liability by a seller.AccountingTools LLC.How to account for prepayments published 19 June 2023, accessed 15 November 2023 Prepaid mobile phones Recent statistics (OECD ''Communications Outlook'' 2005) indicate that 40% of the total mobile phone market in the ...

Camel Application Part
The CAMEL Application Part (CAP) is a signalling protocol used in the Intelligent Network (IN) architecture. CAP is a Remote Operations Service Element (ROSE) user protocol, and as such is layered on top of the Transaction Capabilities Application Part (TCAP) of the SS#7 protocol suite. CAP is based on a subset of the ETSI Core and allows for the implementation of carrier-grade, value added services such as unified messaging, prepaid, fraud control and Freephone in both the GSM voice and GPRS data networks. CAMEL is a means of adding intelligent applications to mobile (rather than fixed) networks. It builds upon established practices in the fixed line telephony business that are generally classed under the heading of (Intelligent Network Application Part) or INAP CS-2 protocol.3GPP TS 29.078 - The 3GPP specification for CAP |
INAP
INAP stands for Intelligent Network Application Protocol or Intelligent Network Application Part. It is the signalling protocol used in Intelligent Networking (IN). It is part of the Signalling System No. 7 (SS7) protocol suite, typically layered on top of the Transaction Capabilities Application Part (TCAP). It can also be termed as logic for controlling telecommunication services migrated from traditional switching points to computer based service independent platform. Applications The International Telecommunication Union (ITU) defines several "capability levels" for this protocol, starting with Capability Set 1 (CS-1).{{cite web , url=https://www.informit.com/library/content.aspx?b=Signaling_System_No_7&seqNum=107 , title=Signaling System No. 7 | Intelligent Network Application Protocol (INAP) , publisher=InformIT , date=2008-07-18 , accessdate=2014-02-26 , archive-url=https://web.archive.org/web/20140304220101/https://www.informit.com/library/content.aspx?b=Signaling_ ...

Interactive Voice Response
Interactive voice response (IVR) is a technology that allows telephone users to interact with a computer-operated telephone system through the use of voice and DTMF tones input with a keypad. In telephony, IVR allows customers to interact with a company's host system via a telephone keypad or by speech recognition, after which services can be inquired about through the IVR dialogue. IVR systems can respond with pre-recorded or dynamically generated audio to further direct users on how to proceed. IVR systems deployed in the network are sized to handle large call volumes and also used for outbound calling as IVR systems are more intelligent than many predictive dialer systems. IVR systems can be used to create self-service solutions for mobile purchases, banking payments, services, retail orders, utilities, travel information and weather conditions. In combination with systems such an automated attendant and automatic call distributor (ACD), call routing can be optimized for a ...

Mobile Phone Operator
A mobile phone operator, wireless provider, or carrier is a mobile telecommunications company that provides wireless Internet GSM services for mobile device users. The operator gives a SIM card to the customer who inserts it into the mobile device to gain access to the service. There are two types of mobile operators: * a mobile network operator (MNO) which owns the underlying network and spectrum assets required to run the service. * a mobile virtual network operator (MVNO) which buys wholesale service from an MNO and sells on to its own customers. (and for years before), the world's largest individual mobile operator by subscribers is China Mobile with over 835 million mobile subscribers. Over 50 mobile operators have over 10 million subscribers each, and over 150 mobile operators had at least one million subscribers by the end of 2009. In February 2010, there were 4.6 billion mobile subscribers, a number that is estimated to grow. Total mobile‐cellular subscriptions r ...

Prepaid Mobile Phone
A prepaid mobile device, also known as a pay-as-you-go (PAYG), pay-as-you-talk, pay and go, go-phone, or prepay, is a mobile device such as a smartphone, phone for which credit is purchased in advance of service use. The purchased credit is used to pay for telecommunications services at the point the service is accessed or consumed. If there is no credit, then access is denied by the cellular network or Intelligent Network. Users can top up their credit at any time using a variety of payment mechanisms such as the Pay as you go, Pay-as-you-go (PAYG). In 2020, 155 countries had the mandatory SIM registration laws for the prepaid mobile SIM cards such as the mandatory Know Your Customer (KYC) or other type of Identity verification service, legal identification verification at the point of sale to prevent the anonymous use of unregistered prepaid mobile which facilitates criminal or terrorist activities.

Mobile Phone
A mobile phone or cell phone is a portable telephone that allows users to make and receive calls over a radio frequency link while moving within a designated telephone service area, unlike fixed-location phones ( landline phones). This radio frequency link connects to the switching systems of a mobile phone operator, providing access to the public switched telephone network (PSTN). Modern mobile telephony relies on a cellular network architecture, which is why mobile phones are often referred to as 'cell phones' in North America. Beyond traditional voice communication, digital mobile phones have evolved to support a wide range of additional services. These include text messaging, multimedia messaging, email, and internet access (via LTE, 5G NR or Wi-Fi), as well as short-range wireless technologies like Bluetooth, infrared, and ultra-wideband (UWB). Mobile phones also support a variety of multimedia capabilities, such as digital photography, video recordin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Toll Free
A toll-free telephone number or freephone number is a telephone number that is billed for all arriving calls. For the calling party, a call to a toll-free number is free of charge, unless air-charges apply for mobile telephone service. A toll-free number is identified by a dialing prefix similar to an area code. The specific service access varies by country. History The features of toll-free services have evolved as telephone networks have evolved from electro-mechanical call switching to computerized stored program controlled networks. Originally, before the automatic system was developed, a call billed to the called party had to be placed through a telephone company operator as a collect call, often long-distance. The operator had to secure acceptance of the charges at the destination number, or even transfer that decision to a long-distance operator, before manually completing the call. Some large businesses and government offices received large numbers of collect calls, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Telephone Company
A telecommunications company is a kind of electronic communications service provider, more precisely a telecommunications service provider (TSP), that provides telecommunications services such as telephony and data communications access. Many traditional solely telephone companies now function as internet service providers (ISPs), and the distinction between a telephone company and ISP has tended to disappear completely over time, as the current trend for supplier convergence in the industry develops. Additionally, with advances in technology development, other traditional separate industries such as cable television, Voice-over IP (VoIP), and satellite providers offer similar competing features as the telephone companies to both residential and businesses leading to further evolution of corporate identity have taken shape. Due to the nature of capital expenditure involved in the past, most telecommunications companies were government owned agencies or privately-owned mono ...

Personal Identification Number
A personal identification number (PIN; sometimes RAS syndrome, redundantly a PIN code or PIN number) is a numeric (sometimes alpha-numeric) passcode used in the process of authenticating a user accessing a system. The PIN has been the key to facilitating the private data exchange between different data-processing centers in computer networks for financial institutions, governments, and enterprises. PINs may be used to authenticate banking systems with cardholders, governments with citizens, enterprises with employees, and computers with users, among other uses. In common usage, PINs are used in ATM or PO transactions, secure access control (e.g. computer access, door access, car access), internet transactions, or to log into a restricted website. History The PIN originated with the introduction of the automated teller machine (ATM) in 1967, as an efficient way for banks to dispense cash to their customers. The first ATM system was that of Barclays in London, in 1967; it accepted ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
