12Sao 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
13Develop 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.
14Deploy 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)
15A 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.
16A 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.

18Parlay 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

52Web 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.
53Web 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
54Web Service technologies Accessing Web Services: SOAP (XML)Describing Web Services: WSDLPublishing Web Services: UDDIWeb Services vs. CORBAWeb ServiceWSDLSOAPUDDICORBAIDLIIOPName Server
55XML Language for defining structured data Example... <customer> <firstname>Johan</firstname><lastname>Svensson</lastname><birthday> </birthday></customer>
56SOAP 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

68Parlay 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)
69SummarizationParlay 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!

72PreparationCopy 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
73How 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.
74How 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.
