Main 3G technologies include UMTS and CDMA2000. Aim of 3GPP was to produce globally applicable technical specifications for third generation mobile systems based on evolved GSM Core Networks and the radio access technology Universal Terrestrial Radio Access (UTRAN). FTP was first defined as a standard in Request for Comments (RFC 959).Glossary 3G 3G refers to next generation of mobile communication systems. and services & systems aspects. These offer enhanced services. such as multimedia and video. Confidential and Proprietary Information of ZTE CORPORATION 229 . It uses the services of Transmission Control Protocol (TCP) to provide reliability in the transfer of data files between network nodes. wireless packet data inter-working. It is comprised of five Standards Development Organizations similar to Organizational Partners in 3GPP. CDMA2000. 3GPP2 mainly deals with the following five areas: A-interface system. FTP A client server application protocol using well known ports 20 and 21. American National Standards Institute-41 (ANSI-41). Access Point An Access Point is a network device which provides the point of interconnection between wireless station (laptop computer. These standards bodies are referred to as Organizational Partners. 3GPP 3GPP was formed in December 1998 as a collaboration agreement bringing together a number of telecommunication standards bodies. Broadband Broadband in radio systems identifies a type of communication channel capable of carrying a large portion of electromagnetic spectrum. It may also be applied to fixed communication systems when referring to bearers capable of carrying high volumes of traffic. GE Gigabit Ethernet (GE) is the Ethernet standard offering Gigabit services and typically employs fibre. Bearer Service Bearer Service is a type of telecommunication service that provides the capability for transmission of signals between access points. PDA) and wired network. This technology has been used for backbone networks and desktops for high end servers and intensive graphical applications. It is comprised of the Mobile Country Code (MCC).

Accounting and Security. Fault.164 defined telephone number used to route telephone calls in a mobile network from a Gateway Mobile Switching Centre (GMSC) to the target MSC. This may be pulses of light. ITU-T have developed a series of standards for Network Management which are referred to as the Telecommunication Management Network (TMN). is the process in which a cellular phone is handed from one cell to the next in order to maintain a radio connection with the network IMEI International Mobile Equipment Identity is a unique identifier allocated to each Mobile Equipment (ME). It consists of a Mobile Country Code (MCC). a Mobile Network Code (MNC) and a Mobile Station Identification Number (MSIN). MSISDN Mobile Station ISDN (MSISDN) Number is the standard international telephone number used to identify a given subscriber. IMSI International Mobile Subscriber Identity is a unique identifier allocated to each mobile subscriber in a GSM and UMTS network. LAI Location Area Identity uniquely identifies a Location Area (LA) within any Public Land Mobile Network (PLMN). or Handover. Configuration. This sub-divides Network Management into the following five categories.164 standard. Iu-CS This is the interface in UMTS which links the Radio Network Controller with MSC Server. MAC Address MAC address refers to hardware address and uniquely identifies a device within a defined network area. usually in an encoded format. MSRN Mobile Station Roaming Number is an E. Iu-PS This is the interface in UMTS which links the RNC with SGSN. RANAP Radio Access Network Application Part (RANAP) is used in a UMTS system on the Iu interface. layers within a station are represented in hierarchical order. high capacity mobile communications offering data rates as high as 2Mbps under stationary conditions with global roaming and other advanced capabilities. reliably. A MS may be allocated two TMSI. UMTS will deliver low cost. hence the introduction of ISDN User Part (ISUP). STCP also detects data corruption. VLR and SGSN must be capable of correlating an allocated TMSI with IMSI of MS to which it is allocated. RAN typically includes a controller Radio Network Controller (RNC) in 3GPP and BSC in 3GPP2 and several transmitter/receivers Node B in 3GPP. QoS Performance of a communications channel or system is usually expressed in terms of Quality of Service (QoS). loss of data and duplication of data by using checksums and sequence numbers. It is responsible for function including setting up of a Radio Access Bearer (RAB) between the Core Network and RNC. priority and other factors specific to each service. Signal to Noise Ratio (SNR). TMSI In order to ensure subscriber identity confidentiality VLR and SGSN may allocate Temporary Mobile Subscriber Identities (TMSI) to visiting mobile subscribers. maximum and mean throughput rate.

SCTP Streaming Control Transmission Protocol (SCTP) is a reliable transport protocol operating on top of IP. SCCP Signalling Connection Control Part is used to provide a means for the transfer of messages between any two signalling points in the same or different SS7 networks. UMTS A 3G mobile communications system which provides an enhanced range of multimedia services. media and content industries to deliver new services and create fresh revenue generating opportunities. Each layer in the protocol stack is defined in generic terms describing functionality and mode of operation. Signaling Gateway A Signaling Gateway is used to support the transport of signalling traffic received from one network and passed into another network. QoS may relate to service performance. as well providing connection to Core Network. BTS in 3GPP2. and the other known as the Packet TMSI (P-TMSI) services provided through the SGSN. The specifications defining UMTS are formulated by 3GPP. UMTS will speed convergence between telecommunications. IT.Glossary Protocol Stack Conceptual model of layered architecture of communication protocols in which. Radio Access Network Radio Access Network (RAN) performs the radio functionality of network.
