What is telecom value-added service

Telecom value-added service refers to the use of public telecommunications network resources and other communication equipment The value realized by the developed additional communication services increases the economic benefits or functional value of the original network. Sometimes called enhanced services.

Value-added services are broadly divided into two categories: one is services in the form of value-added network (VAN). The value-added network can rely on the transmission equipment rented from the public network and use the department's switches, computers and other special equipment to form a private network to meet the needs of the department. For example, fax storage and forwarding networks composed of rented high-speed channels, conference television networks, private packet switching networks, virtual private networks (VPN), etc.; the second is services that appear in the form of value-added services. It refers to services developed in addition to the basic services of the original communication network (telephone and telegraph services), such as database retrieval, data processing, electronic data interchange, electronic mailbox, electronic directory inquiry and electronic file transmission.

The main value-added services currently available on my country’s telecommunications network are:

(1) Electronic mailbox, also known as email. The latest generation of electronic mailboxes is the Message Handling System (MHS), which enables interoperability between dissimilar computers. E-mail provides users with the ability to access and deliver texts, data, charts or other forms of written information. It is usually transmitted through a packet-switched data network, but can also be implemented through a telephone network or a user telegraph network.

(2) Visual text. As an additional value-added service for telephone users, it is interconnected through the database on the public telephone network and the packet switching network. It can retrieve various text and image (color) information on demand, and can also be used as a terminal device for electronic mailboxes.

(3) Electronic data interchange (EDI). It is a means of using computers to conduct trade or information exchange in accordance with prescribed formats and protocols, so it is also called "paperless trade". It is the most modern trade method in developed countries and has been adopted by many countries. The "gold letter" promoted by our country The "golden pass" in the project is the development and application of EDI in our country.

(4) Fax storage and forwarding. It is a device that stores and forwards users' fax signals through a computer or has a fax information retrieval function, providing users with high-performance fax services. Dedicated lines or public packet networks are usually used to provide users on the telephone network with services such as busy retransmission, multi-address or broadcast transmission, scheduled delivery, voice prompt inquiry, and fax/telex conversion. Fax storage and forwarding is non-real-time communication, and the circuit utilization rate can be increased by more than five times. It is a promising business.

(5) Online database search. It connects data terminals or PCs to various information databases through telecommunications networks. With the support of retrieval software, users can easily and quickly obtain the required information and data. In addition to users searching the database directly, users can also easily find the database they need through an intermediary computer system. Its application range is extremely wide, such as scientific and technological information retrieval, news, finance, stocks, futures, flights, trains and other public services. It is also used in various professional databases such as books, chemical industry, light industry, petroleum, etc.

(6) International Internet (Internet), also known as the Internet. It is the world's largest computer Internet, and it is also a value-added service that utilizes existing communication networks and open computer resources. In recent years, the network has developed from a scientific research and educational network into a commercial network. It currently connects more than 150 countries and regions, more than 40,000 computer networks, nearly 4 million computers, and has more than 100 users. Thirty-five million. In order to meet the needs of Chinese users, the Ministry of Posts and Telecommunications uses Beijing, Shanghai, and Guangzhou as the national entrance and exit bureaus to interconnect with the U.S. Internet. Users can access the Chinese Internet Chi?nanet through the telephone network, public packet switching network, e-mail system or dedicated line, and connect with the U.S. Internet. Communication between domestic and foreign Internet users. This network can provide users with services such as e-mail, file transfer, database retrieval, remote information processing, data query, multimedia communication, electronic conference, image transmission, etc.

(7) Voice information service.

The voice platform provides users with voice information services, such as 160 artificially assisted information stations, 168 automatic voice services, and 166 voice mailboxes. Its service scope covers news, sports, technology, finance, securities, real estate, medical care, and entertainment. , transportation, shopping guides, tourism, talent exchanges, hotspot tracking and other aspects, these services are gradually transitioning to the national information network, database retrieval and other methods to achieve maximum sharing of resources.

Others such as "200" telephone calling card service, "800" recipient pay service, virtual private network (VPN) service, centralized user switch service, etc. are all value-added services. There are also some new value-added services such as frame relay services, video conferencing, video on demand (VOD), etc., which are also booming.
