Cell Global Identity

	Cell Global Identity Cell Global Identity (CGI) is a globally unique identifier for a Base Transceiver Station in mobile phone networks. It consists of four parts: Mobile Country Code (MCC), Mobile Network Code (MNC), Location Area Code (LAC) and Cell Identification (CI). It is an integral part of 3GPP specifications for mobile networks, for example, for identifying individual base stations to "handover" ongoing phone calls between separately controlled base stations, or between different mobile technologies. MCC and MNC make up a PLMN identifier, and PLMN and LAC make up a location area identity (LAI), which uniquely identifies a Location Area of a given operator's network. So a CGI can be seen as a LAI with added Cell Identification, to further identify the individual base station of that Location Area. Overview * a CGI (e.g. 001-02-3-4) consists of: a LAI (001-02-3), which consists of: * a PLMN (001-02), which consists of: ** MCC (001) MNC (02) * and a LAC (03), and a CI (4) ...

	Base Transceiver Station A base transceiver station (BTS) is a piece of equipment that facilitates wireless communication between user equipment (UE) and a network. UEs are devices like mobile phones (handsets), WLL phones, computers with wireless Internet connectivity, or antennas mounted on buildings or telecommunication towers. The network can be that of any of the wireless communication technologies like GSM, CDMA, wireless local loop, Wi-Fi, WiMAX or other wide area network (WAN) technology. BTS is also referred to as the ''node B'' (in 3G networks) or, simply, the '' base station'' (BS). For discussion of the LTE standard the abbreviation '' eNB'' for evolved node B is widely used, and GNodeB for 5G. Though the term BTS can be applicable to any of the wireless communication standards, it is generally associated with mobile communication technologies like GSM and CDMA. In this regard, a BTS forms part of the base station subsystem (BSS) developments for system management. It may also have equi ...

	Mobile Country Code The ITU-T Recommendation E.212 defines mobile country codes (MCC) as well as mobile network codes (MNC). Overview The mobile country code consists of three decimal digits and the mobile network code consists of two or three decimal digits (for example: MNC of 001 is not the same as MNC of 01). The first digit of the mobile country code identifies the geographic region as follows (the digits 1 and 8 are not used): * 0: Test networks * 2: Europe * 3: North America and the Caribbean * 4: Asia and the Middle East * 5: Australia and Oceania * 6: Africa * 7: South and Central America * 9: Worldwide (Satellite, Air—aboard aircraft, Maritime—aboard ships, Antarctica) An MCC is used in combination with an MNC (a combination known as an "MCC/MNC tuple") to uniquely identify a mobile network operator (carrier) using the GSM (including GSM-R), UMTS, LTE, and 5G public land mobile networks. Some but not all CDMA, iDEN, and satellite mobile networks are identified with an MCC/MNC t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]

	Mobility Management Mobility management is one of the major functions of a GSM or a UMTS network that allows mobile phones to work. The aim of mobility management is to track where the subscribers are, allowing calls, SMS and other mobile phone services to be delivered to them. Location update procedure A GSM or UMTS network, like all cellular networks, is basically a radio network of individual cells, known as base stations. Each base station covers a small geographical area which is part of a uniquely identified location area. By integrating the coverage of each of these base stations, a cellular network provides a radio coverage over a much wider area. For GSM, a base station is called a base transceiver station (BTS), and for UMTS it is called a Node B. A group of base stations is named a location area, or a routing area. The location update procedure allows a mobile device to inform the cellular network whenever it moves from one location area to the next. Mobiles are responsible for detecti ...

	Handover In cellular telecommunications, handover, or handoff, is the process of transferring an ongoing call or data session from one channel connected to the core network to another channel. In satellite communications it is the process of transferring satellite control responsibility from one earth station to another without loss or interruption of service. Terminology American English uses the term ''handoff'', and this is most commonly used within some American organizations such as 3GPP2 and in American originated technologies such as CDMA2000. In British English the term ''handover'' is more common, and is used within international and European organisations such as ITU-T, IETF, ETSI and 3GPP, and standardised within European originated standards such as GSM and UMTS. The term handover is more common in academic research publications and literature, while handoff is slightly more common within the IEEE and ANSI organisations. Purpose In telecommunications there may be diffe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Public Land Mobile Network In telecommunication, a public land mobile network (PLMN) is a combination of wireless communication services offered by a specific operator in a specific country.3GPP TS 21.905 https://www.etsi.org/deliver/etsi_tr/121900_121999/121905/15.00.00_60/tr_121905v150000p.pdf A PLMN typically consists of several cellular technologies like GSM/ 2G, UMTS/ 3G, LTE/ 4G, offered by a single operator within a given country, often referred to as a cellular network. PLMN code A PLMN is identified by a globally unique PLMN code, which consists of a MCC (Mobile Country Code) and MNC (Mobile Network Code). Hence, it is a five- to six-digit number identifying a country, and a mobile network operator in that country, usually represented in the form 001-01 or 001–001. A PLMN is part of a: * Location Area Identity (LAI) (PLMN and Location Area Code) * Cell Global Identity (CGI) (LAI and Cell Identifier) * IMSI (see PLMN code and IMSI) Leading zeros in PLMN codes Note that an MNC can be of two ...
