Back to today! (Not yet convergent world)
• What do I do before travelling 2 days to Lillehammer?
– I add the appointment to my Outlook Calendar
(already in April)
– I activate ‘out of office assistant’ in Outlook (for e-mail)
or instead I read mail via my Ericsson R380 with WAP
– I program my desktop phone (PABX-based)
• into absence (‘travelling untill ddmm’))
• or into forward to mobile
– I program my mobile not to ring during this presentation

A few examples of hybrid services possible today
• Using some combination of features from
• telecommunication
(PSTN, GSM, SMS, locations, IP-telephony, ...)
• data/IT/content
(calendar, web-pages, work schedules,…)
• media/content
( film trailers, web pages,….)
• and/or broadcast
(e.g. Redaksjon21 (SMS),BigBrother,RingInn,...)

UMTS: new concepts
• VHE (Virtual Home Environment)
– Same services ‘whereever you are’
independent of terminal, access
network,…. (to the extent possible)

OSA (Open Service Access)
• enabling new applications
• may be developped and operated by
3rd parties
• may utilize several features from
several networks
– e.g. combine Internet, mail, (UMS), PSTN
voice and new multimedia networks
• one user: several access types

Parlay (www.parlay.org)
• MERGE IT AND TELECOM.
• Goal : define API’s that provide enterprises
access to network information and allow them to
control a range of network capabilities.

Standardization of Parlay
3GPP R99 (CN5):
• Adoption of Parlay 2.1 APIs : TS 23.127 +TS 29.198
– Framework: Service View
– Generic Call Control
– User Interaction (also for WAP push)
– CAMEL based Mobility Management
– Terminal Capabilities (based on WAP UAProf)
– Data Session (GPRS charging)
• Informative mapping to network protocols: TR 29.998
ETSI (SPAN 3):
• will adopt all Parlay 2.1 APIs, base for ETSI, 3GPP and ITU
June 2001
23
Lill Kristiansen, Ericsson AS
Standardization of Parlay cont’d
Parlay 3.0 / UMTS R04 :
• OSA will become OISP: Open Interface for
Service Providers
• No longer have separate groups: One call control
group (within 3GPP) of Parlay, ETSI and 3GPP.
• Joint document ETSI - 3GPP.

Openness; the crucial role of the OSA Framework
• Framework provides controlled access to Service Capabilities
– authentication of applications (possibly from different domains)
– authorize access to one or more Service Capabilities
• Framework enables incorporation of new Service Capabilities
– enables to include non-standardized capabilities, and make them available
for (some) applications
– enables SCS’s from different vendors

Lill Kristiansen, Ericsson AS
Location application; interaction flow during traffic
• Terminal interacts via WAP with application, selects
ATM location option
Application Server
• application invokes ‘userLocationRequest’ method, gets
response
Application
• application produces suitable map (including term.caps
from WAP GW), provides this to terminal

VHE and OSA; subscriber ownership and openness
• Business model of UMTS VHE (3GPP); Home Environment in
control
– Home Environment (HE) owns subscriber
– Home Environment VAS-provider helps HE to offer service portfolio
– HE-VASP has relationship with HE, but not with subscribers. Examples:
• taxi service (or trafikanten)has agreement with GSM/UMTS operator to get
locations,
– but taxi/trafikanten need not have agreement with the end-user,
– end-user might even be anonymous towards the taxi/trafikanten-service
• web content provider have agreement with GSM/UMTS operator for epayment solutions
– end-user profile such as name, address, creditcard no. etc. reside within
GSM/UMTS operator

OSA Standardization Status and Ericsson Strategy
• UMTS OSA concept originally by Ericsson
• Parlay APIs fit well in OSA concept
• Ericsson joined Parlay and strives to harmonize Parlay and
UMTS OSA, joint effort with ETSI SPAN3
• One API standard, one developer community! Enabling
differentiated services
– 3GPP and ETSI joined forces on UMTS OSA, Parlay as input
– ITU refers to joint 3GPP/ETSI work on API’s
– continuous feedback and alignment with Parlay group
– ensure alignment with JAIN initiative and OMG

Ericsson and Telenor joint OSA project
• prOSA (proof of concept of OSA)
by Telenor Mobil, Telenor R&D,
Ericsson MU and Ericsson IPT:
– Using IPT2.0 for IP-telephony
– Adding OSA onto IPT2.0:
• User status and (Subset of) Call Control
– using call control on an IP-based telephony network
– combining with Gateway from VoIP to PSTN/GSM
• framework

What does Parlay/OSA help create?
• Get new and better services quicker
– e.g. get rid of my 4 ways of availability control
– better GUI’s with standard web/wap technologies
– bigger application developpers community
==> synergy, quicker development, richer applications
• Open up to information not present in ‘the
network’
– e.g. calendar info, friends and buddylists, work schedules (e.g.
which taxis, plumbers, ambulances), bus stop locations,…
– content (information and entertainment)
