Sao Paulo ICT-OSA/Parlay Workshop 2006How to create the next killer service?Need for a foundation consisting of:technology competenceingenuityclear rolesjoined effortprocess understandingvisibilityjoined effortclear rolesReach outingenuityDeploytechnologyDevelop serviceIdentify needKnow thepossibilitiesEricsson AB 2006
9 Know the possibilities Sao Paulo ICT-OSA/Parlay Workshop 2006Know the possibilitiesParlay specifications:Framework (access and authentication)Call Control (voice)User Interaction (SMS, MMS, WAP, )Mobility (geographic location, general status)Terminal Capabilities (phone features)Generic Messaging (message system)Charging (payment)Data Session Control (typically GPRS session management)Connectivity Manager (quality of service, virtual private network)Account Management (charging event notification)Presence and Availability Management (status on various devices)Multi-Media Messaging (voice mail, , multimedia)Policy Management (policy enabled network access)FrameworkHow applications authenticate themselves to the networkHow applications discover what facilities are available from the networkFault managementCall Control - Generic, Multi-party, Conference, & Multi-mediaHow applications set up calls in the networkHow applications set up multi-party (conference) calls in the networkHow applications are used to route calls from the network, e.g. so that an enterprise application can manage call diversions for an employeeHow applications can set up multi-media callsMobility (Location)How applications find the location of a terminalHow applications request notifications when terminals change locationTerminal CapabilitiesHow applications find out the features of the terminalData Session ControlHow applications manage data sessions initiated from terminalsTypically used for GPRS (and other 2.5G) applicationsGeneric MessagingHow applications interact with messaging systems, such as voice, FAX orConnectivity ManagerHow applications manage Quality of Service (QoS) and the configuration of Virtual Private Networks (VPNs)Account ManagementHow applications query accounts and charge historyChargingHow applications request payment for services (“content-based charging”)How applications reserve payment for a future servicePresence and Availability ManagementHow applications manage presence “I am at my computer” / “I am away”and availability “I am in a meeting” / “I am available to be contacted”Typically used in Instant Messaging types of applications and their extension to wireless networksPolicy ManagementHow applications interact with policy-enabled networksEricsson AB 2006
10 Know the possibilities Parlay X specifications:Third Party Call (application generated calls)Call Notification (call information)Short Messaging (sms)Multimedia Messaging (mms)Payment (charging)Account Management (balance information)Terminal Status (state of terminal)Terminal Location (geographic position)Call Handling (rule management)Audio Call (playing audio)Multimedia Conference (group “broadcasts”)Address List Management (user group management)Presence (messaging availability)
11 Know the possibilities Locate Operator / Service EnablerList supported Parlay servicesGet the preferred Gateway Supplier resourcesLocate Gateway SupplierGet compliance statement from current Gateway SupplierGet Parlay SDK (API, Simulators, Examples)Choose implementation specificsProgramming languageGood IDE (Borland JBuilder, Eclipse, Visual Studio .NET)
12 Sao Paulo ICT-OSA/Parlay Workshop 2006 Identify a needInnovate on mobility as a key differentiatorReuse existing resources and technologies (simple solutions may yet be very powerful)Limit the service dependency – service by service approachEricsson AB 2006
13 Develop service Consider various PGW vendors for their support in: Code libraries, Application Program Interfaces (APIs)Test tools, Simulators, EmulatorsDocumentation, Guides, TrainersParlay Standard compliancePartnership program availabilityExample applicationsAccess to online forums and customer supportCertificationAccess standard specifications and download IDL (Parlay) or WSDL (Parlay X) files to generate code stubs.
14 Deploy To mass market and/or to target a specific PGW / Operator Network protocol considerationsVisibility to the end user (how to promote service)Visibility for the developer (who are buying)Visibility for the operator / service enabler (who are selling)
15 A Parlay example - Foundation Know the possibilities:Parlay User Interaction (SMS & MMS)Parlay Mobility (User Location)Identify a need:Hard to find somewhere to eat (mobility)Develop service:Java development on Eclipse using the Ericsson Network Resource Gateway Software Development Kit.Deploy:Local Swedish operator agrees to become the “first offer” customer.
16 A Parlay example – Use Case Sending SMS to a service number will return a MMS with directions for the nearest restaurant that matches the criteria of the search. User can then optionally decide to call the restaurant to make reservations.

18 Parlay example – Patterns Sao Paulo ICT-OSA/Parlay Workshop 2006Parlay example – PatternsGUIIpApp_XXConfigurationMainIpApp_XX_AdapterFeatureXX_Processor• Main — Initializes, starts, stops and terminates the example application.Initializing — refers to the process of reading configuration,showing the GUI, etc.Starting and Stopping — refer to the process of initiating andterminating execution of the feature logic (the H-OSA interaction).Terminating — refers to the process of closing the GUI and exitingthe example application.Configuration — provides the example application with configurationdata. It defines which parameters exist and how the configuration fileshould be parsed.GUI — provides a simple graphical user interface. The GUI is a windowthat contains an area for showing e.g. a description of the exampleapplication, and an area that holds buttons such as a button to start theexample application.Feature — implements the logic (i.e. the functional behavior) of theexample application. It uses an FWproxy class to obtain (and release) theservice managers from the NRG that are used by the processors.YY_Processor — interacts with the NRG. It shields the Featureclass from H-OSA details that are not relevant for the exampleapplication logic. It uses a service manager (Ip_XX_Manager) tosend requests to the NRG, and extends a service manager callbackadapter (IpApp_XX_ManagerAdapter) to receive callback responses.Processors extend the callback adapter rather than implement a callbackinterface directly. As a result, each processor only needs to implementthose callback methods that are relevant within the scope of the exampleapplication/processor.feature can have multiple processors (for example, the GroupSMS exampleapplication uses a processor for determining whether or not a subscriber’sphone is reachable, but also a processor for receiving and sending SMSIp_XXEricsson AB 2006

52 Web ServicesWeb services, in the general meaning of the term, are services offered by one application to other applications via the World Wide Web.Clients of these services can aggregate them to form an end-user application, enable business transactions, or create new Web services.In a typical Web services scenario, a business application sends a request to a service at a given URL using the SOAP protocol over HTTP. The service receives the request, processes it, and returns a response.
53 Web Services Web services are software components that Are described and found using XML technologiesCan be accessed with standards-based internet protocolsHTTPHTTPSSMTPExchange XML-formatted dataClient and service may be implemented with different languages on different hardware and software platforms
54 Web Service technologies Accessing Web Services: SOAP (XML)Describing Web Services: WSDLPublishing Web Services: UDDIWeb Services vs. CORBAWeb ServiceWSDLSOAPUDDICORBAIDLIIOPName Server
55 XML Language for defining structured data Example... <customer> <firstname>Johan</firstname><lastname>Svensson</lastname><birthday> </birthday></customer>
56 SOAP Simple Object Access Protocol XML-based message format Defines a message between the sender and an ultimate receiverpossibly via intermediariesEnvelopeHeaderBodyHeaders can be targeted at certain intermediariesThe SOAP message transfer is done by another underlying protocol. HTTP is standardized but SMTP and other are possible

68 Parlay X benefits No need to authenticate all requests towards the PGW Simplified, more abstract less detailedEasy popular functions (good enough)Targets web based applications and Web ServicesEasy network configurations (http posts)Good tools available for WSDL stub generation (AXIS or JWSDP)
69 SummarizationParlay X services are Web Service components sent by SOAP calls defined by WSDL usually over HTTPMain benefits are the simplification of access and authorizationComponent based programmingMuch of the implementation is done by the WSDL compiler that generate stubs to use in your codeParlay X makes network resource access faster and simpler than ever before!

71 Sao Paulo ICT-OSA/Parlay Workshop 2006 PARLAY & PARLAY X DEVELOPMENT TRAININGPart OneEricsson AB 2006
72 PreparationCopy the parlay_training_course.zip file onto your computerUnzip it to any location without spaces in the path (C:\Documents and Settings should be avoided!) Preferably use something similar to c:\parlayDisable any firewall currently active on your laptop as it might disallow certain ports to be used
73 How to work with this package Use runEclipse to start the Eclipse IDE.In Eclipse there are several projects, either for Parlay or Parlay X that will illustrate a certain feature of the standard.Each exercise has a solution. Use the solution to compare your results but try your best before doing so.Each exercise will take about 30 minutes. (Some less some more). First there will be an introduction and last will be a summarization of the intended solution.
74 How to work with this package Use runSimulator to start the Ericsson Network Resource Gateway Simulator, this will act as a PGW, phones and a network emulator on your local laptop.The Simulator needs to be running in order for the Parlay applications to work.In order to run the Parlay X applications you need to have an Internet access.
