1 Cellular Network
2 Basic Goals of Networking Call management Call setup Call termination Different Service: voice over IP, call forwarding, 2
3 Basic Goals of Networking User Information Transport Modulation Duplexing Multiple Access Frequency Bands Above factors define channels Physical channels Logical channels traffic channel vs. control channel 3
4 Networking Issues Mobility Management How do you find users when calls arrive for them? Registration to keep track of users (HLR/VLR) Paging to connect calls Authentication and Encryption for Network Security Need to have better security and privacy than wired line Radio Resource Management Channel Reservation for handoff calls Maintaining call quality: power control Resource efficiency 4
5 Networking Issues Operation, Administrations and Maintenance (OAM) Traffic Monitoring Quality Monitoring 5
6 Network Elements Networking is system dependent AMPS is an example It s not cellular system It s an air-interface standard i.e. Protocol between mobile unit and BS Traffic channel: analog Control channel: digital 6
7 Network Components Air-interface PSTN MS BS T1/E1 MSC 7
8 Air-Interface between Mobile and BS Traffic channel Dedicated Control channel: call setup Intra-call Control channel: Handoff calls, Power control 8
9 Traffic channel xdma/xdd Modulation: FM in AMPS Channel spacing: 30kHz in AMPS, 25 khz by CEPT Frequency Band 9
10 Dedicated Control channel For call setup, frequency assignment, handoff Forward control channel (FOCC): paging channel Reverse control channel (RECC): Access channel Every cell site has one dedicated control channel in each direction 10
11 Dedicated Control channel A digital channel with ECC In AMPS, 10kbps/30kHz Repeat every message 5 times: A form of time diversity Standard Block ECC Forward (40, 28) code: kbps after overhead Reverse (48, 36) code: kbps 11
12 Intra-call Control Channel (Voice channel) In-band signaling over the voice channel to convey system control message 1) SAT (Supervisory Audio Tone) 2) ST (Signaling Tone) 3) Blank and Burst 12
13 Base Station Broadcasting signals Constantly monitors signal strength of on-going calls Locator receiver is used for handoff calls Radio link is a trunked system No trunking over the wired line from BS to MSC 13
14 MSC Switching function Administration/control function Database for billing Database for locations of users either in the system (HLR) or out of the system (VLR) Database for state of the system - cells, adjacent cells - available channels in every cell site - users signal that is degrading and requires handoff Authentication task for billing, verification of valid users 14
15 MSC Trend 1) Centralized core function to MSC Billing, Authentication 2) Distributed function to BSC/RNC Handoff, call control, channel assignment Mobile BS BSC/RNC MSC 15
16 AMPS AMPS consists of 1) Cellular idea 2) Spectrum allocation 3) Air-Interface standard Spectrum Allocation MHz: Mobile tx MHz: Mobile rx 50MHz/30kHz = 1664 ch 2 = 832 Duplex ch 2 = 416 Duplex ch/ carrier 21 control, 395 traffic 16
17 AMPS Air-interface standard AMPS developed by AT&T AMPS adopted by EIA and TIA: EIA/TIA 553 Standard EIA/TIA 533 standard Modulation scheme Voice filtering Power control Call setup/termination, Handoff protocol Structure of message 17
18 Digital in Wireless 1st Generation Cellular: AMPS (Analog) 2nd Generation Cellular: (Digital ) GSM: One Pan-European Standard Increase Capacity over Analog USDC (IS-54): Increase Capacity over AMPS CDMA (IS-95): Increase Capacity over AMPS 3rd Generation Cellular: UMTS/IMT-2000 (Digital) WCDMA: voice, video telephony, web document, VOD CDMA
19 Digital in Wireless All 2nd Generation Digital standards introduce ECC Interleaving Equalization (not in CDMA) Low rate vocoding (LPC, ) Encryption Embedded data channel MAHO 19
20 GSM, 2G Cellular Group System Mobile, Global System Mobile Goal 1. Pan-European standard (full international roaming) 2. To provide many different services voice, data service, pager 3. Security 4. Increased capacity: 20
21 GSM GSM is a comprehensive standard Air-interface standard: Mobile-BS Interface between BS and MSC BS system (to serve micro-cells) BTS: radio equipment BSC: network control operation and signal processing 21
22 Radio Tx in GSM Two 25 MHz Band : uplink : down link TDMA/FDD 200kHz radio carrier 1 frame (26frame/120ms) with 8 time slots Reverse frame is 3 TS retarded relative to the forward frame: unnecessary for a terminal to tx and rx simultaneously 22
23 GSM frequency bands and physical channel GSM frequency bands GSM physical channel 23
24 GSM frames and slots 24
25 Contents of a GSM time slot 25
26 Logical Channels Traffic channel: TCH/F: 22.8 kbps TCH/H: 11.4 kbps Control channel (signaling channel): Broadcast channel: Common control channel: Dedicated control channel: 26
