5. Design Perspectives
Transaction management perspective: the designed architecture must provide the base for construction/implementation of efficient transaction processing scheme that can solve existing transaction management problems;
Communication network perspective: the designed architecture must support the mechanisms for dealing with different communication network types specifics (user mobility, frequent disconnections, network domain infrastructure, etc.);
Service management perspective: the designed architecture must enable possible differentiation of services to be provided with respect to concrete user preferences.

Terminal and location independence
Distributed service execution
End-to-end service negotiation
Shared service knowledge introduction
Service export/import to/from other networks/Internet

15. 2G (GSM) Service Architecture
Mobile device authentication: HLR location report
Circuit switching of radio channels
SMS is limited packet data service
Services are mutually exclusive
Internet access via WAP GW only
Restricted WML support
No asynchronous applications

16. 2.5G (GPRS, EDGE)
Mobile device authentication: Gateway GPRS Support Node (GGSN)
IP addressing of mobiles by GGSN
Traffic differentiation
Support for CS GSM and PS GPRS
Data transfer reliability and radio efficiency
Operator’s multimedia services

17. 2.5G: JAIN SIP
Session Initiation Protocol (SIP) belongs to JAIN API family
SIP server is used to setup multimedia communication between end-points
Parlay-API can be added to SIP server to execute servlets on a web server
Scripted mobile code can be sent for execution to application client

18. 2.5G: Parlay Parlay API is based on CORBA interfaces
Allows hosting applications outside specific networks while accessing network resources
Relies upon operator-installed gateways
Open and techology-independent
Requires synchronization between application client and server
Services can move only within Parlay domains

19. 2.5G: Parlay Architecture

20. 3G Phase 1 (UMTS)
Mobile device authentication: combined Support GPRS Support Node (SGSN) and GGSN
IP addressing by combined SGSN/GGSN
Real-time and isochronous multimedia over wireless end-to-end connectivity
Services are platform-unique and cannot be exported/imported to/from Internet

21. 3G Phase 1:VHE Virtual Home Environment(VHE) provides
service portability accross network boundaries
UI personalization
location-independent access to services
For UMTS VHE consists of
GSM services
Roaming principles
Service capabilities

22. Virtual Home Environment Architecture

23. 3G Phase 2
Mobile device authentication and IP addressing: integrated SGSN and GGSN (IGSN) sends information to AAA-server and HLR
Services are negotiated end-to-end, also outside the service network
Necessity of dynamic restoring service shared knowledge inside mobile device

24. 4G
Public locations provide broadband Internet access and are equipped with WLAN extensions
High bandwidth (up to 11 Mbps)
High scalability due to mobility mechanisms (Mobile-IP, IPv6)
No traditional subscription for Internet access (e.g.E-Cash)
Third party services without intervention of network operator

25. Internet Service Architectures
Universal Plug & Play (UPnP) and JINI
enable devices use each other’s services dynamically
JINI uses a server; UPnP relies upon a control point, co-located with the resource
Registration of profiles and resources, and event services
Tuple Spaces
Devices and resources share common application knowledge
Special tuple-server, and hence scaling problem

32. Service Classification
Three main types of service classification can be considered:
Execution Site based classification
Equipment based classification
Functional classification

33. Execution Site Based Classification
Refers to classifying the services according to the site in the network where the services are executed
Server based services – executed on server side
User terminal based services – executed locally on user terminals
Network based services – performed by network functionality

34. Equipment Based Classification
Refers to classifying the services into groups according to network standard or applied equipment capabilities
Network specific services – services specific for certain network standard or for certain network hardware
User terminal specific services – services specific for certain terminal capabilities

35. Functional Classification
Refers to classifying the services according to useful function performed by them
Communication services – services which enable communication between two or more network users
Content Delivery services – services which enable information delivery to users in appropriate form
Remote Management services – services which enable a user to remotely accomplish certain activities through the network

36. Existent and possible mobile services
