Motivation – Why get involved?
Sao Paulo ICT-OSA/Parlay Workshop 2006 Motivation – Why get involved? HTML for the WWW Global availability “Access to anywhere, whenever” Fat clients (PC) Often fixed Parlay for the Telecom Personal availability “Access to anywhere, whenever from wherever” Thin clients (Phone) Often portable Getting access to the bank in the middle of the night. Getting access to the bank in the middle of the night in a taxi from the airport. With mobility comes new needs and new opportunities Mobility adds a new dimension for service creation! Ericsson AB 2006

How to create the next killer service?
Sao Paulo ICT-OSA/Parlay Workshop 2006 How to create the next killer service? Need for a foundation consisting of: technology competence ingenuity clear roles joined effort process understanding visibility joined effort clear roles Reach out ingenuity Deploy technology Develop service Identify need Know the possibilities Ericsson AB 2006

Know the possibilities
Sao Paulo ICT-OSA/Parlay Workshop 2006 Know the possibilities Parlay 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) Framework How applications authenticate themselves to the network How applications discover what facilities are available from the network Fault management Call Control - Generic, Multi-party, Conference, & Multi-media How applications set up calls in the network How applications set up multi-party (conference) calls in the network How applications are used to route calls from the network, e.g. so that an enterprise application can manage call diversions for an employee How applications can set up multi-media calls Mobility (Location) How applications find the location of a terminal How applications request notifications when terminals change location Terminal Capabilities How applications find out the features of the terminal Data Session Control How applications manage data sessions initiated from terminals Typically used for GPRS (and other 2.5G) applications Generic Messaging How applications interact with messaging systems, such as voice, FAX or Connectivity Manager How applications manage Quality of Service (QoS) and the configuration of Virtual Private Networks (VPNs) Account Management How applications query accounts and charge history Charging How applications request payment for services (“content-based charging”) How applications reserve payment for a future service Presence and Availability Management How 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 networks Policy Management How applications interact with policy-enabled networks Ericsson AB 2006

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)

Locate Operator / Service Enabler List supported Parlay services Get the preferred Gateway Supplier resources Locate Gateway Supplier Get compliance statement from current Gateway Supplier Get Parlay SDK (API, Simulators, Examples) Choose implementation specifics Programming language Good IDE (Borland JBuilder, Eclipse, Visual Studio .NET)

Identify a need Innovate on mobility as a key differentiator Reuse existing resources and technologies (simple solutions may yet be very powerful) Limit the service dependency – service by service approach Ericsson AB 2006

Develop service Consider various PGW vendors for their support in:
Code libraries, Application Program Interfaces (APIs) Test tools, Simulators, Emulators Documentation, Guides, Trainers Parlay Standard compliance Partnership program availability Example applications Access to online forums and customer support Certification Access standard specifications and download IDL (Parlay) or WSDL (Parlay X) files to generate code stubs.

Deploy To mass market and/or to target a specific PGW / Operator
Network protocol considerations Visibility to the end user (how to promote service) Visibility for the developer (who are buying) Visibility for the operator / service enabler (who are selling)

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.

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.

Parlay example – Sequence
Sao Paulo ICT-OSA/Parlay Workshop 2006 Parlay example – Sequence Consumer PGW Application 1. create notification 2. send sms 2. report notification 3. get user location 4. report user location 5. get info Access and authentication not shown Managers and callbacks Asynchronous communication 5. send mms 6. receive mms Ericsson AB 2006

Parlay example – Patterns
Sao Paulo ICT-OSA/Parlay Workshop 2006 Parlay example – Patterns GUI IpApp_XX Configuration Main IpApp_XX_Adapter Feature XX_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 and terminating execution of the feature logic (the H-OSA interaction). Terminating — refers to the process of closing the GUI and exiting the example application. Configuration — provides the example application with configuration data. It defines which parameters exist and how the configuration file should be parsed. GUI — provides a simple graphical user interface. The GUI is a window that contains an area for showing e.g. a description of the example application, and an area that holds buttons such as a button to start the example application. Feature — implements the logic (i.e. the functional behavior) of the example application. It uses an FWproxy class to obtain (and release) the service managers from the NRG that are used by the processors. YY_Processor — interacts with the NRG. It shields the Feature class from H-OSA details that are not relevant for the example application logic. It uses a service manager (Ip_XX_Manager) to send requests to the NRG, and extends a service manager callback adapter (IpApp_XX_ManagerAdapter) to receive callback responses. Processors extend the callback adapter rather than implement a callback interface directly. As a result, each processor only needs to implement those callback methods that are relevant within the scope of the example application/processor. feature can have multiple processors (for example, the GroupSMS example application uses a processor for determining whether or not a subscriber’s phone is reachable, but also a processor for receiving and sending SMS Ip_XX Ericsson AB 2006

Parlay Gateway Access A P application server(s) application 1 4 5(+) Parlay/OSA P G W 2 3 6(+) service(s)) framework service capability server(s) Application registers with the framework and provides authentication and requested service id Once the application is authorized the framework will contact the service and retrieve the service manage together with the SLA information. The service crates a SLA manager for the application. The service returns a manager reference that the application may use The Framework returns the service manager to the application The application now starts communication directly to the application. The framework is only contacted again for service termination. MM7 PAP SMPP SMTP N E T WAP GW MMC SMSC Ericsson AB 2006

Parlay Gateway – Lifecycle
Restaurant analogy Where do you want to eat? (IP on port?) Request menu (Get PGW services) Call on waiter (Chose service manager) Order food (Send service request) Receive food (Receive response) Eat food (Perform action on response) Start all over again (optional) Pay and leave (Dispose resources and disconnect) Initialization phase Execution phase Termination phase

Parlay example - Initialization
Sao Paulo ICT-OSA/Parlay Workshop 2006 Parlay example - Initialization Getting access to services Application Framework 1: initiateAuthentication 2: selectEncryptionMethod 3: authenticate 4: authenticationSucceeded 5: authenticate 6: authenticationSucceeded Application initiates authentication on frameworks public interface application provides what encryption it supports application request the framework to answer a challenge to authenticate it self application signals that the authentication succeeded the application and framework exchange challenges and responses to authenticate each other framework signals that it authenticated application the application request the framework for a access interface _ In this third step the application requests for a service that matches its needs by tuning the service properties This method is used by the client application to identify the service that the client application wishes to use. If the client application is not allowed to access the service, then the P_SERVICE_ACCESS_DENIED exception is thrown. application requests to start the SLA signing application is requested to sign the “contract” to use the service the framework is also requested to sign the “contract” now approved by the application 7: requestAccess 8: obtainInterfaceWithCallback 9: obtainInterface 10: discoverService 11: selectService 12: initiateSignServiceAgreement 13: signServiceAgreement 14: signServiceAgreement Ericsson AB 2006

Benefit for the whole industry
Public interface to access the telecom network resources (availability) Any IT application on any telecom network (portability) “Off-the-shelves” market computer components (ATX standard) analogy batteries analogy Definition of roles and business processes  Key actor specialization

Cross dependencies Parlay / Parlay X Application Developer
clear requirements Parlay / Parlay X Application Developer Service Provider enhanced services easier implementation loyalty easier maintenance increased traffic richer services Network operator Consumer cheaper traffic LESS TEAMWORK = LESS BENEFIT

Application Developer
Definition Software oriented innovator and creator of stable and easy manageable services for the telecom community Rights Limit requirement scope together with Service the Provider and decide technology consideration together with the Network Operator. Responsibilities Must verify and test implementation as agreed with the Service Provider and Network Operator

Parlay / Parlay X benefits Simple Effortless startup - easy to learn! Notifications, Requests and Responses No need for telecom specific knowledge CAPv2, CAPv3, CS1, CS1+, SIP are available only for voice communication Learn one! That’s enough! Similar pattern for all Parlay and Parlay X services Shared common data (TpAddress) Common programming language of choice IDL/WSDL generation Less code – easier debugging Full set API’s, Utility classes simplify reoccurring events

Parlay / Parlay X benefits Powerful Access to capabilities new to the IT industry positioning availability / access Wide variety of intuitive mappings towards available telecom services Location, Status, Messaging, Voice, Charging… Stable Create once, run anywhere Isolation from network changes Farewell spaghetti code!

Parlay / Parlay X benefits Revolutionizes the developer possibilities Less operator dependency Free market, everyone’s invited! Free development tools = small risks = low costs! Possible to develop a new service for your mobile phone within days instead of weeks True integration of IT and Telecom

Network Operator Definition Rights Responsibilities
Infrastructure oriented enabler of stable and accessible services for the telecom community Rights Determine access distributed in the system Runtime and maintenance considerations Responsibilities Authorization, Availability, Authentication

Network Operator Parlay / Parlay X benefits
Popular services increase traffic Increased traffic equals higher revenues Easier maintenance with presumably fewer bugs Statistical information of the traffic Simple control over network resources

Service Provider Definition Rights Responsibilities
Market analyzer close to the telecom service consumer Rights Decides requirements together with the Application Developer and the Network Operator To receive fully tested and verified service solutions that are persistently available to the consumer Responsibilities Discover needs and foresee future expectations

Service Provider Parlay / Parlay X benefits Less development costs
Faster time to market New types of services, increased level of interaction New markets Increased customer loyalty Business monitoring and surveillance through statistics Business rules (load etc.)

Consumer Definition Rights Responsibilities
User of the telecom system, predominantly uninterested in the technology and implementation specifics Rights Stable and accessible services at justified prices Responsibilities Financier of the telecom network system maintenance, operating costs and research and development.

Consumer Parlay / Parlay X benefits Timelier deliveries
World Cup in football Fuller range of personalized services Richer, more satisfying experience Cheaper services (??)

Summarization An “off-the-shelves” solution makes common sense!
Need for a teamwork understanding of the telecom industry Definition of once role(s) is the first step to become true specialists in a certain area – too broad scope may slow down progress Lot of benefits throughout the telecom community – biggest risk is that networks will not open up Parlay is the standard to make this happen

PARLAY & PARLAY X BENEFITS Part Two: Parlay and Parlay X at a comparison Ericsson AB 2006

Agenda Parlay and Parlay X overview
Sao Paulo ICT-OSA/Parlay Workshop 2006 Agenda Parlay and Parlay X overview Web Services Fitting Parlay X into the picture Technologies overview Comparison between Parlay and Parlay X Simple working example Summarization Ericsson AB 2006

Web Services Web 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.

Web Services Web services are software components that
Are described and found using XML technologies Can be accessed with standards-based internet protocols HTTP HTTPS SMTP Exchange XML-formatted data Client and service may be implemented with different languages on different hardware and software platforms

Web Service technologies
Accessing Web Services: SOAP (XML) Describing Web Services: WSDL Publishing Web Services: UDDI Web Services vs. CORBA Web Service WSDL SOAP UDDI CORBA IDL IIOP Name Server

XML Language for defining structured data Example... <customer>
<firstname>Johan</firstname> <lastname>Svensson</lastname> <birthday> </birthday> </customer>

SOAP Simple Object Access Protocol XML-based message format
Defines a message between the sender and an ultimate receiver possibly via intermediaries Envelope Header Body Headers can be targeted at certain intermediaries The SOAP message transfer is done by another underlying protocol. HTTP is standardized but SMTP and other are possible

SOAP – the envelope metaphor
Functional aspects SOAP Send MMS to User X Application Ericsson 1 Euro Send request Receive request Receive letter (Platform) Read letter (Application) Post letter Write letter Msg: 1:2 TransId: 352 To: Vodafone From: Yahoo Verified by: Verisign Approved by: User X Authentication Authorization Confidentiality Integrity Privacy Transaction (Coordinated) Reliable … Maybe payments? Non-functional aspects

SOAP Message structure SOAP Envelope SOAP Header SOAP Body
Information individually targeted for intermediaries and end points SOAP Body Information for the ultimate receiver

WSDL Web Service Description Language
Describes what a service does Available operations Input and output messages How a service is accessed Data encoding format Protocols supported Where a service is located Service endpoint URL In our case the Parlay X WSDLs are standardized and downloadable from internet (e.g.

UDDI Universal Description, Discovery and Integration
Registry for businesses and their Web Services Name of business Contact information Type of business Interfaces (WSDL) Access information (URL)

Parlay X A set of simple Web Services
Simple and high level access to widely used telecom functions Aimed at Web developers Leading to: A principle: Keep Interface Specifications Simple “Limited” sets of building blocks for web developers Number of developers Thousands Parlay-X Parlay/OSA Voice & data protocols Hundreds Network detail

Parlay and Parlay X compared
More complex More complete functionality CORBA based Publish/Find via Parlay Framework SLA/Policy negotiation via Parlay Framework Authentication via Parlay Framework Parlay X Simple Limited functionality Web Services based Publish/Find via UDDI – Industry standard SLA/Policy negotiation via local bind process (not the same level) Authentication via WS-Security

A Parlay X example Send SMS message
Find the appropriate WSDL file(s) ( Find a suitable WSDL compiler for the programming language of choice ( Compile the WSDL files to get the stubs and interfaces needed to create the SOAP message Make certain that proper security credentials are added as SOAP message headers (operator specific) Use a URL to identify where the service is located Invoke the service interface method to send the SOAP message

Parlay X benefits No need to authenticate all requests towards the PGW
Simplified, more abstract less detailed Easy popular functions (good enough) Targets web based applications and Web Services Easy network configurations (http posts) Good tools available for WSDL stub generation (AXIS or JWSDP)

Summarization Parlay X services are Web Service components sent by SOAP calls defined by WSDL usually over HTTP Main benefits are the simplification of access and authorization Component based programming Much of the implementation is done by the WSDL compiler that generate stubs to use in your code Parlay X makes network resource access faster and simpler than ever before!

PARLAY & PARLAY X DEVELOPMENT TRAINING Part One Ericsson AB 2006

Preparation Copy the parlay_training_course.zip file onto your computer Unzip it to any location without spaces in the path (C:\Documents and Settings should be avoided!) Preferably use something similar to c:\parlay Disable any firewall currently active on your laptop as it might disallow certain ports to be used

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.

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.
