Subsystem Number
Signalling Connection Control Part (SCCP) subsystem numbers are used to identify applications within network entities which use SCCP signalling. GSM and UMTS SSNs In Global System for Mobile Communications (GSM) and Universal Mobile Telecommunications System (UMTS), subsystem numbers may be used between Public land mobile networks (PLMNs), in which case they are taken from the globally standardized range (1 - 31) or the part of the national network range (129 - 150) reserved for GSM/UMTS use between PLMNs. For use within a PLMN, numbers are taken from the part of the national network range (32 - 128 & 151 - 254) not reserved for GSM/UMTS use between PLMNs. The following globally standardized subsystem numbers have been allocated for use by GSM/UMTS: 0 Not used/Unknown 1 SCCP MG 6 HLR (MAP) 7 VLR (MAP) 8 MSC (MAP) 9 EIR (MAP) 10 is allocated for evolution (possible Authentication Centre).

SMLC
Serving Mobile Location Center In GSM Networks, the SMLC is a network element that resides in the BSC (Base Station Controller) and calculates network-based location of mobile stations (handsets). The SMLC may control several LMUs (Location Measurement Units), which measure radio signals to help find mobile stations in the area served by the SMLC. It can calculate location using the TA (Timing Advance) method. The SMLC communicates with the GMLC {{context, date=January 2020 The Gateway Mobile Location Centre (GMLC) contains functionality required to support location-based service (LBS).

Intelligent Network
The Intelligent Network (IN) is the standard network architecture specified in the ITU-T Q.1200 series recommendations. It is intended for fixed as well as Global System for Mobile Communications, mobile telecommunication, telecom networks. It allows operators to differentiate themselves by providing value-added services in addition to the standard telecom services such as PSTN, ISDN on fixed networks, and GSM services on Mobile phone, mobile phones or other mobile devices. The intelligence is provided by network nodes on the service layer, distinct from the telephone exchange, switching layer of the core network, as opposed to solutions based on intelligence in the core telephone exchange, switches or equipment. The IN nodes are typically owned by telecommunications service providers such as a telephone company or mobile phone operator. IN is supported by the Signaling System 7, Signaling System #7 (SS7) protocol between network switching centers and other network nodes owned by ...

Local Number Portability
Local number portability (LNP) for fixed lines, and full mobile number portability (FMNP) for mobile phone lines, refers to the ability of a "customer of record" of an existing fixed-line or mobile telephone number assigned by a local exchange carrier (LEC) to reassign the number to another carrier ("service provider portability"), move it to another location ("geographic portability"), or change the type of service ("service portability"). In most cases, there are limitations to transferability with regards to geography, service area coverage, and technology. Location Portability and Service Portability are not consistently defined or deployed in the telecommunication industry. In the United States and Canada, mobile number portability is referred to as WNP or WLNP (Wireless LNP). In the rest of the world it is referred to as mobile number portability (MNP). Wireless number portability is available in some parts of Africa, Asia, Australia, Latin America and most European countri ...

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_S ...

GGSN
The GPRS core network is the central part of the general packet radio service (GPRS) which allows 2G, 3G and WCDMA mobile networks to transmit IP packets to external networks such as the Internet. The GPRS system is an integrated part of the GSM network switching subsystem. The network provides mobility management, session management and transport for Internet Protocol packet services in GSM and WCDMA networks. The core network also provides support for other functions such as billing and lawful interception. It was also proposed, at one stage, to support packet radio services in the US D-AMPS TDMA system, however, in practice, all of these networks have been converted to GSM so this option has become irrelevant. PRS module is an open standards driven system. The standardization body is the 3GPP. GPRS tunnelling protocol (GTP) ''GPRS Tunnelling Protocol'' is the defining IP-based protocol of the GPRS core network. Primarily it is the protocol which allows end users of ...

RANAP
In telecommunications networks, RANAP (Radio Access Network Application Part) is a protocol specified by 3GPP in TS 25.413 and used in UMTS for signaling between the Core Network, which can be a MSC or SGSN, and the UTRAN. RANAP is carried over Iu-interface. RANAP signalling protocol resides in the control plane of Radio network layer of Iu interface in the UMTS (Universal Mobile Telecommunication System) protocol stack. Iu interface is the interface between RNC (Radio Network Controller) and CN (Core Network). nb. For Iu-ps transport RANAP is carried on SCTP if IP interface used on this. RANAP handles signaling for the Iu-PS - RNC and 3G SGSN and Iu-CS - RNC and 3G MSC . It also provides the signaling channel to transparently pass messages between the User Equipment (UE) and the CN. In LTE, RANAP has been replaced by S1AP. In SA (standalone) installations of 5G, S1AP will be replaced by NGAP. Functionality Over the Iu interface, RANAP is used to: - Facilitate general UTRAN ...

Base Station Subsystem
The base station subsystem (BSS) is the section of a traditional cellular telephone network which is responsible for handling traffic and signaling between a mobile phone and the network switching subsystem. The BSS carries out transcoding of speech channels, allocation of radio channels to mobile phones, paging, transmission and reception over the air interface and many other tasks related to the radio network. Base transceiver station The base transceiver station, or BTS, contains the equipment for transmitting and receiving radio signals (transceivers), antennas, and equipment for encrypting and decrypting communications with the base station controller (BSC). Typically a BTS for anything other than a picocell will have several transceivers (TRXs) which allow it to serve several different frequencies and different sectors of the cell (in the case of sectorised base stations). A BTS is controlled by a parent BSC via the "base station control function" (BCF). The BCF is imp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
