Design Goals Flexibility Extensibility Re-configurability Scalability Service Mobility User Mobility Heterogeneous Data (Services) Integration Adaptive Communication Deregulated Access

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.

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

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

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

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

Real-time and isochronous multimedia over wireless end-to-end connectivity

Services are platform-unique and cannot be exported/imported to/from Internet

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

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

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

Service Classification

Three main types of service classification can be considered:

Execution Site based classification Equipment based classification Functional classification

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

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

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

Business Models Provide flexible and well defined

foundation for design and management of complicated corporate service architectures. They define: Business entities and roles Reference points for business relationships Service provision procedures and

frameworks

Business Models in E-Commerce

B2B – Business to business

B2C – Business to consumer

C2B – Consumer to business

A2A – Application to Application

C2C – Consumer to Consumer

M2M – Market to market

Business Models in E-Commerce

Peer-to-peer (machine to machine, with or without human guidance)

B2B2C – Business to Business to Consumer

Direct Commerce – Vendor Managed Inventory shipped directly from warehouses

Collaborative Commerce – Multiple partners working to supply a seamless experience

Transparent Commerce – a persona with data wake that predictably engages commerce
