June 2001 Lill Kristiansen, Ericsson AS 5 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 ) 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

June 2001 Lill Kristiansen, Ericsson AS 6 I continuously update my calendar :

June 2001 Lill Kristiansen, Ericsson AS 8 How do I handle during absence

June 2001 Lill Kristiansen, Ericsson AS 9 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,...)

June 2001 Lill Kristiansen, Ericsson AS 12 Today on PC: type in your location into web-page:

June 2001 Lill Kristiansen, Ericsson AS 13 Tomorrow: Avoid typing, get location automatic e.g. into WAP page (or into SMS content) Bank services Location services Leisure News

June 2001 Lill Kristiansen, Ericsson AS 19 UMTS: new concepts VHE (Virtual Home Environment) –Same services ‘whereever you are’ independent of terminal, access network,…. (to the extent possible)

June 2001 Lill Kristiansen, Ericsson AS 20 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

June 2001 Lill Kristiansen, Ericsson AS 21 Parlay and UMTS Open Service Access; Migration and Convergence

June 2001 Lill Kristiansen, Ericsson AS 22 Parlay ( MERGE IT AND TELECOM.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.

June 2001 Lill Kristiansen, Ericsson AS 23 Standardization of Parlay 3GPP R99 (CN5): Adoption of Parlay 2.1 APIs : TS TS –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 ETSI (SPAN 3): will adopt all Parlay 2.1 APIs, base for ETSI, 3GPP and ITU

June 2001 Lill Kristiansen, Ericsson AS 24 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.

June 2001 Lill Kristiansen, Ericsson AS 25 framework Loc.informationCall control Service capability server(s) Interface class OSA interface Open Service Architecture discovery Application server HLRCSE Msg. server WAP server 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 MMoIP* *MMoIP: H323 GK in R’99 SIP server in R04

June 2001 Lill Kristiansen, Ericsson AS 26 Location application; interaction flow before traffic Application registers and authenticates towards FW FW checks SLA, and starts suitable UserLocationManager, returns reference to application

June 2001 Lill Kristiansen, Ericsson AS 27 Location service for private subscribers full example this time…. Bank services Location services Leisure News

June 2001 Lill Kristiansen, Ericsson AS 28 Location service for private subscribers Directions From To ATM Bank Police Default

June 2001 Lill Kristiansen, Ericsson AS 29 Location service for private subscribers

June 2001 Lill Kristiansen, Ericsson AS 30 Location application; interaction flow during traffic Terminal interacts via WAP with application, selects ATM location option application invokes ‘userLocationRequest’ method, gets response application produces suitable map (including term.caps from WAP GW), provides this to terminal

June 2001 Lill Kristiansen, Ericsson AS 31 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 e- payment solutions –end-user profile such as name, address, creditcard no. etc. reside within GSM/UMTS operator

June 2001 Lill Kristiansen, Ericsson AS 32 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 OSA Standardization Status and Ericsson Strategy

June 2001 Lill Kristiansen, Ericsson AS 34 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

June 2001 Lill Kristiansen, Ericsson AS 37 Prototyping 2: Trial Participants and contact persons: Full presentation of this demo can be downloaded from (project manager)

June 2001 Lill Kristiansen, Ericsson AS 38 Some Market Objectives for the Trial Telenor: Explore the possibility to open up the value chain Define service provider ’ s requirements Development of new services based on integration of IP and telephone network access Service initiated call (Call out of the blue) Ericsson: Get operator, vendor and 3rd party working together Refine elements of Ericsson Parlay Developer Support program (see Net4Call: Verify the Service provider ’ s requirements Verify the business model

June 2001 Lill Kristiansen, Ericsson AS 39 Some Technical Objectives for the Trial Telenor Test of 3G service platform based on Parlay/OSA Network Integration Network and SLA Security Requirements Capacity and load testing Ericsson: Test the Jambala SCS Parlay\OSA Gateway in a live network Parlay Framework Parlay Services Verify the integration needs of implementing an end-to-end Parlay based solution Net4Call: Test of Net4Call Parlay/OSA Connector Test of Net4Call Service Suite

June 2001 Lill Kristiansen, Ericsson AS 40 Services tested Net4Call –Net4Call Parlay Connector functionality Framework Call Control User Interaction – Net4Call Phone, Net4Call 800, Net4Call FindMe Telenor –Click to Call –Number translation

June 2001 Lill Kristiansen, Ericsson AS 41 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)

June 2001 Lill Kristiansen, Ericsson AS 42 Richer applications! Just compare... Customizing mail-handling depending on ….
