What Can We Learn from the LTA ? (1)

Platforms must be carrier-grade> Communications applications are real-time

• While the passenger is waiting for information, the bus may already have passed by...

> Scalable from a few to hundreds of bus users

• Service must work at peak and off-peak hours...

> Reliable and always available• Passengers won’t change habits unless the service works !• It’s about money: no swindling with charging and payment



Services may implement highly distributedand complex business processes> Interaction between different players/partners

• Bus Co, Telco, G.I.S. provider, banks• Distribution of systems, services and data• Each party must be able to manage his own assets

> Flexible rating, charging and payment• Occasional users, family accounts, bonus schemes, …• Prepaid/postpaid, debit/credit, e-wallet, …

> User orientation and simplicity• Simple to explain and easy to use !• All implementation complexity must be hidden from the user



Need for common integration tools> Network Systems Integration

• Adaptation to network protocols and dialects• Control of heterogeneous, multi-vendor networks? INAP - CAMEL - SIP - DIAMETER - COPS - ...

> Systems Integration• Partner and 3rd party business logic and data (EAI)• Operators’ communications applications (CAI)• Operators’ business applications (OSS/BSS)

? XML Web Services look like a good choice ...


What’s Missing to Make LTA Real ? (1)

A robust underlying foundation and network> Always availability and fairness

• “Web service not reachable” is not acceptable

> Real-time with guaranteed QoS• To support multimedia and streaming

> Privacy and security• For web service providers and web service users• Fraud resistance (no “denial of service”)

The “WEB NET”The “WEB NET”



A common “service infrastructure”> Trust and service brokering

• Taking web-services beyond “peer to peer”• Similar to the Parlay Framework

> Sharing of User Profile Data• Service personalisation and customisation

> Rating - charging - payment• Web services charged on Telco payment system• Easy settlement between all parties

The “WEB GRID”The “WEB GRID”



Services - Services - Services> Web service components in all ICT domains

• Conversation, messaging, user interaction, work-flow, information access, management, etc.

> Applications composed with these components• Driven by end-user needs, not by technology

> Simple web service creation and integration tools• To address non ICT professionals

“WEB APPS”“WEB APPS”


Opportunities for Telcos

Providing the WEB NET> Real-time, scalable and reliable> Using network features like QoS, security, distribution

Building the WEB GRID> A reliable infrastructure for sharing and brokering> Rating - charging - payment services

Offering WEB APPS> Real-time communication components

• Session control, routing, messaging, IVR, management, …> Applications based on web technology

• For own OSS/BSS use and for the market
