3 Architecture of the GSM system GSM is a PLMN (Public Land Mobile Network) several providers setup mobile networks following the GSM standard within each country GSM system comprises 3 subsystems Radio Access Network: covers all radio aspects MS (mobile station) BSS (base station subsystem) or RAN (radio access network) BTS (base transeiver station) BSC (base station controller) Core Network: call forwarding, handover, switching MSC (mobile services switching center) LR (location register): HLR and VLR OMC (operation and maintenance centre) AuC (authentication centre) EIR (equipment identity register) 3

4 GSM: cellular network segmentation of the area into cells possible radio coverage of the cell cell idealized shape of the cell use of several carrier frequencies not the same frequency in neighboring cells cell radius varies from some 100 m up to 35 km depending on user density, geography, transceiver power etc. hexagonal shape of cells is idealized (cells overlap, shapes depend on geography) if a mobile user changes cells -> handover of the connection to the neighbor cell 4

5 Cellular systems: Frequency planning I Frequency reuse only with a certain distance between the base stations Typical (hexagon) model: f 4 f 5 f 6 reuse-3 cluster: f 3 f 1 reuse-7 cluster: f 1 f 3 f 2 f 7 f 3 f 1 f 2 f 3 f 1 f 4 f 5 f 1 f 6 f 4 f 5 f 6 f 2 f 2 f 3 f 2 f 7 f 1 f 3 f 2 f 7 Other regular pattern: reuse-19 the frequency reuse pattern determines the experienced SIR Fixed frequency assignment: certain frequencies are assigned to a certain cell problem: different traffic load in different cells Dynamic frequency assignment: base station chooses frequencies depending on the frequencies already used in neighbor cells Frequency Hopping (fixed or random sequence of frequencies) Improves quality for slow moving or stationary users (frequency diversity) Reduces impact of intercell interference by statistical averaging 5

6 GSM: Air Interface FDMA (Frequency Division Multiple Access) / FDD (Frequency Division Duplex) Uplink 890 MHz 915 MHz Downlink 935 MHz 960 MHz khz frequency TDMA (Time Division Multiple Access) Downlink Uplink ,615 ms = 1250 bit time 6

7 GSM: Voice Coding Voice coding Channel coding Framing Modulation (GMSK) 114 bit/slot bit GSM TDMA frame ms Guard (8.25 bits): avoid overlap with other time slots (different time offset of neighboring slot) Training sequence: select the best radio path in the receiver and train equalizer Tail: needed to enhance receiver performance Flag S: indication for user data or control data GSM time-slot (normal burst) guard space tail user data S Training S user data tail 3 bits 57 bits 1 26 bits 1 57 bits 3 guard space µs 577 µs 7

8 Mobile Terminated Call (MTC) 1: calling a GSM subscriber 2: forwarding call to GMSC 3: signal call setup to HLR 4, 5: request MSRN from VLR 6: forward responsible MSC to GMSC 7: forward call to current MSC calling station 8, 9: get current status of MS 10, 11: paging of MS 12, 13: MS answers 14, 15: security checks 16, 17: set up connection PSTN 1 2 BSS HLR 3 6 GMSC BSS VLR MSC MS BSS

9 Location Management / Mobility Management The issue: Compromise between minimizing the area where to search for a mobile minimizing the number of location updates Solution 1: Large paging area RA RA Solution 2: Small paging area Location RA Update TOTAL Signalling Cost + = Paging Signalling Cost Paging Area Update Signalling Cost RA RA Location RA Update RA Location Update RA Location Update Location Update RA 9

10 Handover The problem: Change the cell while communicating Reasons for handover: Quality of radio link deteriorates Communication in other cell requires less radio resources Supported radius is exceeded (e.g. Timing advance in GSM) Overload in current cell Maintenance Link quality cell 1 cell 2 cell 1 cell 2 Handover margin (avoid ping-pong effect) Link to cell 1 Link to cell 2 time 10

SRES Authentication Response (SRES 32 bit) SRES K i : individual subscriber authentication key SRES: signed response 12

15 GPRS (General Packet Radio Service) Introducing packet switching in the network Using shared radio channels for packet transmission over the air: multiplexing multiple MS on one time slot flexible (also multiple) allocation of timeslots to MS (scheduling by PCU Packet Control Unit in BSC or BTS) using free slots only if data packets are ready to send (e.g., 115 kbit/s using 8 slots temporarily) standardization 1998, introduction 2001 advantage: first step towards UMTS, flexible data services GPRS network elements GSN (GPRS Support Nodes): GGSN and SGSN GGSN (Gateway GSN) interworking unit between GPRS and PDN (Packet Data Network) SGSN (Serving GSN) supports the MS (location, billing, security) HLR (GPRS Register GR) maintains location and security information 15

16 GPRS: Multiplexing and multislot allocation Multiplexing TS carrier Multislot capability

17 GPRS services End-to-end packet switched traffic (peak channel rates) 28 kbps (full use of 3 time slots, CS-1: FEC) kbps (full use of 8 time slots, CS-4: no FEC) Average aggregate throughput of a cell (Source: H. Menkes, WirelessWeb, Aug. 2002) 95 kbps (for both up and downlink) Assumptions: 4/12 reuse, realistic RF conditions, random traffic Worse figures for individual TCP traffic Adaptive Coding Schemes (adaptive Forward Error Control FEC) CS 1: 9.05 Kbps/slot CS 2: 13.4 Kbps/slot CS 3: 15.6 Kbps/slot CS 4: 21.4 Kbps/slot (no FEC) Problems and limits IP-based network => high latency, no guarantees Limited data rate: 28 kbps (3 slot/cs-1) kbps (3 slot/cs-4) Latency/flow control problems with TCP 17

18 EDGE (Enhanced Data Rates for GSM Evolution) Enhanced spectral efficiency depends on: Size of frequency band Duration of usage Level of interference with others (power) Near-far problem EDGE Technology: EDGE can carry data speeds up to kbit/s for 4 timeslots (theoretical maximum is kbit/s for 8 timeslots) Adaptation of modulation depending on quality of radio path GMSK (GSM standard 1 bit per symbol) 8-PSK (3 bits per symbol) Adaptation of coding scheme depending on quality of radio path (9 coding schemes) Gain: data rate (gross) up to 69,2kbps (compare to 22.8kbps for GSM) complex extension of GSM!
