Media Gateway Control Protocol Architecture
The media gateway control protocol architecture is a methodology of providing telecommunication services using decomposed multimedia gateways for transmitting telephone calls between an Internet Protocol network and traditional analog facilities of the public switched telephone network (PSTN). The architecture was originally defined in RFC 2805 and has been used in several prominent voice over IP (VoIP) protocol implementations, such as the Media Gateway Control Protocol (MGCP) and Megaco (H.248), both successors to the obsolete Simple Gateway Control Protocol (SGCP). The architecture divides the functions required for the integration of traditional telecommunication networks and modern packet networks into several physical and logical components, notably the media gateway, the media gateway controller, and signaling gateways. The interaction between the media gateway and its controller is defined in the media gateway control protocol. Media gateway protocols were developed bas ...

Cellular Network
A cellular network or mobile network is a communication network where the link to and from end nodes is wireless. The network is distributed over land areas called "cells", each served by at least one fixed-location transceiver (typically three cell sites or base transceiver stations). These base stations provide the cell with the network coverage which can be used for transmission of voice, data, and other types of content. A cell typically uses a different set of frequencies from neighboring cells, to avoid interference and provide guaranteed service quality within each cell. When joined together, these cells provide radio coverage over a wide geographic area. This enables numerous portable transceivers (e.g., mobile phones, tablets and laptops equipped with mobile broadband modems, pagers, etc.) to communicate with each other and with fixed transceivers and telephones anywhere in the network, via base stations, even if some of the transceivers are moving through more than ...

Softswitch
A softswitch (''software switch'') is a call-switching node in a telecommunications network, based not on the specialized switching hardware of the traditional telephone exchange, but implemented in software running on a general-purpose computing platform. Like its traditional counterparts it connects telephone calls between subscribers or other switching systems across a telecommunication network. Often a softswitch is implemented to switch calls using voice over IP (VoIP) technologies, but hybrid systems exist. Although the term ''softswitch'' technically refers to any such device, it is conventionally applied to a device that handles IP-to-IP phone calls, while the phrase '' access server'' or "media gateway" is used to refer to devices that either originate or terminate traditional land line phone calls. In practice, such devices can often do both. An access server might take a mobile call or a call originating from a traditional telephone line, convert it to IP traffic, then s ...

ITU-T
The ITU Telecommunication Standardization Sector (ITU-T) is one of the three sectors (divisions or units) of the International Telecommunication Union (ITU). It is responsible for coordinating standards for telecommunications and Information Communication Technology such as X.509 for cybersecurity, Y.3172 and Y.3173 for machine learning, and H.264/MPEG-4 AVC for video compression, between its Member States, Private Sector Members, and Academia Members. The first meeting of the World Telecommunication Standardization Assembly (WTSA), the sector's governing conference, took place on 1 March of that year. ITU-T has a permanent secretariat called the Telecommunication Standardization Bureau (TSB), which is based at the ITU headquarters in Geneva, Switzerland. The current director of the TSB is Chaesub Lee (of South Korea), whose first 4-year term commenced on 1 January 2015, and whose second 4-year term commenced on 1 January 2019.

Network-based Call Signaling
Network-based Call Signaling (NCS) is a profile of the Media Gateway Control Protocol (MGCP) for use in PacketCable applications for voice-over-IP. A network implementing NCS is designed according to the media gateway control protocol architecture for interconnecting a packet network with the traditional public switched telephone network (PSTN). This architecture physically decomposes the functionality of providing complete end-to-end multimedia telecommunication sessions into several discrete components, notably a media gateway (MG) located at the customer premises that performs the physical translation between analog voice or video streams to packetized digital data, and a media gateway controller (MGC) which is a centralized server that controls typically many media gateways and manages the complexity of call setup, resource negotiation, call routing, and tear-down. In addition, the architecture also uses signaling gateways to the traditional telecommunication channels, such as ...

PacketCable
PacketCable network is a technology specification defined by the industry consortium CableLabs for using Internet Protocol (IP) networks to deliver multimedia services, such as IP telephony, conferencing, and interactive gaming on a cable television infrastructure. The PacketCable technology is based on the DOCSIS base with extensions that enable cable operators to deliver data and voice traffic efficiently using a single high-speed, quality-of-service (QoS)-enabled broadband (cable) architecture. The PacketCable effort dates back to 1997 when cable operators identified the need for a real-time multimedia architecture to support the delivery of advanced multimedia services over the DOCSIS architecture. The original PacketCable specifications were based on the physical network characteristics of operators in the U.S. For the European market, Cable Europe Labs, maintains a separate, but equivalent effort, ''EuroPacketCable'', based on European network implementations.

Internet Standard
In computer network engineering, an Internet Standard is a normative specification of a technology or methodology applicable to the Internet. Internet Standards are created and published by the Internet Engineering Task Force (IETF). They allow interoperation of hardware and software from different sources which allows internets to function. As the Internet became global, Internet Standards became the lingua franca of worldwide communications. Engineering contributions to the IETF start as an Internet Draft, may be promoted to a Request for Comments, and may eventually become an Internet Standard. An Internet Standard is characterized by technical maturity and usefulness. The IETF also defines a Proposed Standard as a less mature but stable and well-reviewed specification. A Draft Standard was an intermediate level, discontinued in 2011. A Draft Standard was an intermediary step that occurred after a Proposed Standard but prior to an Internet Standard. As put in RFC 2026: In ge ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Lucent
Lucent Technologies, Inc. was an American Multinational corporation, multinational telecommunications equipment company headquartered in Murray Hill, New Jersey, Murray Hill, New Jersey. It was established on September 30, 1996, through the divestiture of the former AT&T Technologies business unit of AT&T Corporation, which included Western Electric and Bell Labs. Lucent was merged with Alcatel SA of France on December 1, 2006, forming Alcatel-Lucent. Alcatel-Lucent was absorbed by Nokia in January 2016. Name Lucent means "light-bearing" in Latin (language), Latin. The name was applied for in 1996 at the time of the split from AT&T. The name was widely criticised, as the logo was to be, both internally and externally. Corporate communications and business cards included the strapline 'Bell Labs Innovations' in a bid to retain the prestige of the internationally famous research lab, within a new business under an as-yet unknown name.
