It is therefore expected that the vast majority of current GSM operators will become involved in deploying UMTS networks GSM Evolution Towards UMTS : GSM Evolution Towards UMTS Evolution of GSM towards UMTS can be explained in terms of “generations”: The entire cellular systems since intoduced has effectively been replaced at times. These major changes are referred to as a new “generation” of cellular systems. 2.5G Standard A Transition 2G-3G : 2.5G Standard A Transition 2G-3G HSCS High Speed Circuit Switched Data Enhancement to the GSM standard Utilises: Multiple channel coding schemes (4.8kbps, 9.6kbps, 14.4kbps per timeslot) Multiple timeslots Circuit Switched Data rates to 57.6kbps 4 slots with 14.4kbps channel coding per slot GPRS : GPRS General Packet Radio Service Enhancement to the GSM standard Utlilises Multiple Timeslots Packet Switching Packet Switched Data typically to rates of 56kbps Theoretically 171.2kbps for 8 timeslots UMTS Introduces serving GPRS support node - SGSN EDGE : EDGE Enhanced Data for GSM Evolution Sometimes called E-GPRS (Enhanced GPRS) Enhancement to the GSM and TDMA standards Utlilises: 8PSK Modulation Possible 1.6 MHz carrier under IS-136 8 Channel Coding Schemes Multiple Timeslots (similar frame structure to GSM) TDMA Data up to rates of 384kbps (typically less) Difference GSM and UMTS : Difference GSM and UMTS Major difference is air interface – GSM: TDMA and FDMA – UMTS: Wide-band code division multiple access (WCDMA) UMTS Modes : UMTS Modes UMTS UMTS-FDD UMTS-TDD UMTS FDD : UMTS FDD • Universal Mobile Telecommunications System Frequency Division Duplexing Mode • Built onto enhanced GSM core network • Utilises: • QPSK modulation (Quadrature phase shift keying) • Multiple channel coding and bearer rates • Variable spreading factors and multi-code transmission • CDMA • FDD • Asynchronous operation • Data up to rates of 2Mbps UMTS TDD : UMTS TDD Universal Mobile Telecommunications System Time Division Duplexing Mode Built onto enhanced GSM core network Utilises: QPSK modulation Multiple channel coding and bearer rates CDMA TDD Asynchronous operation • Data up to rates of 2Mbps • Will happen after UMTS FDD Slide 13: UMTS Architecture Overview User Equipment UE : User Equipment UE The UMTS UE is based on the same principles as the GSM MS— the separation between mobile equipment (ME) and the UMTS subscriber identity module (SIM)card (USIM). UE consists of : · Display and User Interface · Holds the Authentication Algorithms and keys · User End Termination of the Air Interface · Application Platform Slide 17: Mobile Equipment The radio terminal is used for radio communication over the Uu interface UMTS Subscriber Identity Module The smartcard that holds the subscriber identity, authentication and encryption keys Etc Terminal Equipment The terminal equipment connects to the UE. This carries the application specific user interface General Core Network Architecture : General Core Network Architecture Home Location Register (HLR) The database storing the master copy of a users profile Visitor Location Register (VLR) The database holding a copy of a visiting users profile Mobile Switching Centre (MSC) Switch for Circuit Switched Services Gateway MSC (GMSC) Serving GPRS Support Node (SGSN) Router for Packet Switched Services Gateway GPRS Support Node (GGSN) UMTS Terrestrial Radio Access Network UTRAN : UMTS Terrestrial Radio Access Network UTRAN Node B Acts as the radio basestation (BTS in GSM) Converts the data flow between the Iub and Uu interfaces RNC • Responsible for the use and integrity of the radio resources within the RNS • Responsible for the handover decisions that require signalling to the UE • Provides a combining/splitting function to support macrodiversity between different Node Bs Major Interfaces in UMTS : Major Interfaces in UMTS • There are four major new interfaces defined in UMTS • Iu The interface between UTRAN and the CN • Iur The Interface between different RNCs • Iub The interface between the Node B and the RNC • Uu The air interface Radio Planning for UMTS : Radio Planning for UMTS Principle Design Considerations There are two design considerations when planning a 3G network. 3G is a multiservice network and 3g requires the practical implementation of WCDMA Planning can be broken into 3 phases : Planning can be broken into 3 phases Dimensioning: To determine the approximate number of sites, cells and number of network elements. · Radio Link Budget · Coverage Analysis · Capacity estimation · Required numbers of network elements eg RNC’s Detailed planning: Involves the use of a radio network planning tool.
