22 Theoretical bitrates Theoretical bitrates seem to remain theory Specified rates are: Circuit Switched bit Packet Switched bit Coverage Type rate (kbit/s) rate (kbit/s) 144 kbit/s 144 kbit/s peak rate Basic coverage,rural/suburban, fast moving vehicles, outdoor 384 kbit/s 384 kbit/s peak rate Extended Coverage, urban, moving vehicles, outdoor 2 Mbit/s 2 Mbit/s peak rate Hot Spot areas, urban, centre, walking speeds, indoor In commercial deployments maximum bit rates are expected to be 384 kbit/s and basic service bit rate 64 kbit/s Indoor coverage for UMTS? One issue is also the availability of high speed terminals 22

23 Quality of Service Radio capacity optimisation Core Network and UTRAN independent from each other and surrounding networks Transport Network optimisation QoS classes: Conversational class: minimum fixed delay, no buffering, symmetric traffic, guaranteed bit rate = Real Time Traffic Streaming class: minimum variable delay, buffering allowed, asymmetric traffic, guaranteed bit rate = Near Real Time Traffic Interactive class: moderate variable delay, buffering allowed, asymmetric traffic, no guaranteed bit rate = Not Real Time Traffic Background class: big variable delay, buffering allowed, asymmetric traffic, no guaranteed bit rate = Data synchronisation 23

24 Quality of Service (cont.) QoS parameters in UMTS: Maximum bit rate (kbit/s) Guaranteed bit rate (Kbit/s) Allowed transfer delay (ms) UE UTRAN CN Is QoS class negotiable? UMTS End-to-end Service UMTS Bearer Service: Request for UMTS QoS Class RAB Assignment Request RRM: - Admission Control QoS Negotiation Radio Bearer and Radio Link establishment RAB Assignment Response UMTS Bearer Service with Negotiated QoS RAB = Radio Access Bearer, RRM = Radio Resource Management 24

25 Quality of Service (cont.) Conversational Streaming Interactive Background Max. Bit < 2048 < 2048 < 2048 < 2048 rate (kbit/s) Guaranteed < 2048 < 2048 N/A N/A Bit rate (kbit/s) Symmetry Symmetric Asymmetric Asymmetric Asymmetric Transfer delay (ms) > 250 N/A N/A Challenges: First typical use cases will be in hybrid networks (UMTS/GPRS/GSM), How is this taken into account? How much can content compression and background synchronisation solve user needs? 25

26 Service capabilities Principle: Connections are separated from service maintaining Network components called service capabilities = service platforms Initially identified service capabilities (Release 99) WAP Server / WAP Gateway - Mobile browser capabilities Positioning servers - UE position information, Location Based Services Mobile Station Application Execution Environment - Provides information to other services about UE information handling capabilities UMTS SIM Application Toolkit (USAT) - SIM card handling tools Customised Applications for Mobile network Enhanced Logic (CAMEL) - Service interconnection point (Service control, implementation and provisioning) 26

27 Service capabilities (cont.) In Release 4 there are new possibilities for service creation OSA = Open Service Architecture Common centralized point for Service Creation = Service Creation Environment (SCE) All capabilities implemented are accessible via APIs Practically CAMEL is required for effective service creation Possibility to make the services roam between networks Challenge: Will the operators open the networks for open service creation? 27

28 Location Communication Services There are different methods to provide UE position information to services or users Cell ID based positioning Round-Trip Time (RTT) based positioning Timing Advance, Received Signal Strength (TA/Rx) Time-of-Arrival (TOA) positioning Time Difference of Arrival (TDOA) positioning Enhanced Observed Time difference (E-OTD) Angle of Arrival (AOA) positioning Reference Node Based Positioning (RNBP) Assisted Global Positioning System (Assisted GPS) 28

29 Accuracy of different positioning systems Always an estimate Different methods for different usage Most accurate isn t always the best choise GPS E-OTD TA/Rx Cell-ID 10m 100m 1 km 10 km Accuracy 29

31 MExE Terminals will have different capabilities - how to tell to the service which are the current capabilities? Mobile Application Execution Environment (MExE) was introduced to handle terminal capabilities MExE Classmark 1: Numeric keypad, limited screensize, fixed character amounts (WAP type Terminal) MExE Classmark 2: Colour screen, full keypad, wide application support (JAVA supporting terminal) MExE Service Environment: Set of supported services Personalisation database - interacts with USIM 31

32 USAT USIM Application Toolkit Extension to GSM SIM Application Toolkit to support USIM properties Applications executed in USIM Most likely to be closed environment - operators are in control of USAT applications 32

33 CAMEL SCE Customised Applications for Mobile network Enhanced Logic - Developed to provide automatic roaming with full service set - Mobility and Service Portability on top of IN Circuit Switched Call Control Subscriber Location and State Retrieval GPRSinterworking CAMEL - functioning environment Subscription Data Handling SMS - MMS Mobility Management 33

34 Virtual Home Environment Idea: To have the same, personalised individual interface through the terminal regardless of the UMTS network the user is attached to Requirements for Release 99 based network are based on CAMEL Subscriber profiles are handled in MExE Service Environment Location Based Services information can be transferred through CAMEL Provisioned services and their usage information is transferred between Networks through CAMEL Number portability can be handled through CAMEL Question: Would this be easier in All IP environment? 34

35 Service Concepts GSM inherited Services supported in R99 are quite BASIC: Voice FAX Alternate FAX/Voice Circuit Switched Data Bearer services Supplementary Services USSD (Unstructured Supplementary Service Data) MMS Packet Switched Services are actually same as in GPRS, but Bigger bit rate Smaller delay 35

36 UMTS Security There are three key principles behind 3G security: 3G security will build on the security of second generation systems. Security elements within GSM and other secondgeneration systems that have proved to be needed and robust shall be adopted for 3G security. 3G security will improve on the security of second generation systems - 3G security will address and correct real and perceived weaknesses in second generation systems. 3G security will offer new security features and will secure new services offered by 3G. 36

37 UMTS Security (cont.) High Level objectives of security: To ensure that information generated by or relating to a user is adequately protected against misuse or misappropriation; Environments are adequately protected against misuse or misappropriation; To ensure that the security features standardised are compatible with worldwide availability. (There shall be at least one ciphering algorithm that can be exported on a worldwide basis (in accordance with the Wassenaar agreement)); To ensure that the security features are adequately standardised to ensure world-wide interoperability and roaming between different serving networks; To ensure that the level of protection afforded to users and providers of services is better than that provided in contemporary fixed and mobile networks (including GSM); To ensure that the implementation of 3GPP security features and mechanisms can be extended and enhanced as required by new threats and services. 37

ISUP) IPSec is needed to ensure integrity of SIP-sessions» Still no decision of end-to-end multimedia session ciphering 43
