The Origins of ORCA

• The Technology and Operations (“TOPS”) Council undertakes important strategic initiatives based on Board direction to meet the industry’s long-term technology needs and achieve member business objectives.

– The Unified Client Architecture Focus Group (UCA-FG) was launched to assess tools that will enable software developers to integrate core network capabilities into their applications.

• UCA-FG considered opportunities for WebRTC clients to access network functionality in a network-independent manner.

• The UCA-FG’s work led to the creation of ORCA, or Open Real-time Communications APIs.

to extend core network capabilities

into any device

Initial Focus - WebRTC

7

Enhanced Device Capabilities

• A WebRTC-enabled web browser – on any device – has the capability to deliver real-time audio and video.– WebRTC (real time communication) enables real-time

audio and video as part of other web-based applications.

– Potential to enable new capabilities for communications services:

• Customer interaction• Conferencing• Interactive sites• Integration of voice/videocommunications into a web environment

8

WebRTC Strategic Opportunity• Proposed WebRTC services do not leverage network

functionalities.

• Opportunity exists for WebRTC developers to connect to service providers’ networks and leverage network services:– QoS – Security– Interoperation– Reliability– Routing infrastructure/

session control/presence

WebRTC specifies media handling for real-time communications,but does not specify signaling for call setup.

E2E Quality of Experience Across Multiple Domains

Solution: Open Real-time Communications API

• Provide developers with ability to access network functions.

• JavaScript Library with APIs is necessary to access and utilize network services:– Enables developers to more easily

develop applications and enhances time-to-market

– Promotes service providers’ core capabilities that may otherwise not be leveraged

– Provides consistent access to network functionality

Phase 1: Harmonization for Call Control API

Potential WebRTC Based Communications Services

15

Call control:• Incoming call alert (including

callerID info)• Call origination • Call termination• Call hold• Call transfer• Prioritize and transport SDP offer

to remote end• Add/drop additional party

(conferencing)• Call waiting alert (including

callerID info)• Add/drop stream (video, sharing,

IM)

Presence:• Status control• Subscription• Change notification

Registration:• Client registration• Authentication (leveraging UICC?) CS Fallback (local API only):• Call handoff (webRTC->CS, CS-

>webRTC)

Other:• Network address book access (at

least retrieve access)• Network flow selection (in support

of QoS)• Network selection (wifi, 3G, 4G,

etc)

16

Traditional Interoperability Approach

1.Develop Standards

2.Compliant Implementations

3.Network Deployment

Standards Promote Interoperability

17

Interoperability in the Internet Age

1.Prototype2.Refine

3.Standardize(where necessary)

Rough Consensus, and Running Code

18

• ORCA is not a traditional standards project.

• Requires different skills:

– Contributions are actual code

– Must understand software development process

– Experience with Git

– Open source expertise

• Get involved in ORCA today

ORCA: A Different Kind of Project

ORCA Testing and Support Requirements

ORCA API Testing

• Applications that use ORCA APIs will require infrastructure to support testing and integration.

• Multiple levels of testing support are envisaged:

– Basic “reflector” to run in developer environment

– Test IMS environment

– Service Provider / Vendor developer programs

– Live network testing

• This presentation will discuss immediate requirements for a basic “reflector”.

21

ORCA Testing: Basic Reflector

• Aim:

– Allow developers to test client implementations

– Run entirely within developer infrastructure

– Be available on GitHub to download by developers

• Not supported:

– High availability

– Scaling for multiple clients

– High performance

Provides first level test environment

Functions Supported

• The basic backend “reflector” will support:– Register: allow client to register willingness to

receive WebRTC request – Call: allow a second client to initiate a call to a

previously allocated client – Reject: allow the registered client to reject the call

request– Accept: allow registered clients to accept the call

request– Disconnect: allow either party to terminate the

call– Event: notify the parties in the call of a change of

status (incoming call, call accept, call reject, disconnect etc.)

24

Future enhancements

• PSTN: Enable calls to/from PSTN / PLMN• NAT / Firewalls: Support traversing of

firewalls• Security: Provide authentication and

authorisation• Robustness: Be highly available and

scalable

25

Summary

• The basic backend “reflector” will allow application developers to complete initial verification of applications with ORCA functionality.

• Additional backend functionality will be made available as required.

Device Solutions Initiative (DSI)Overview

Problem StatementIntegrating network-based service enablers such as call signaling or network control requires developers to adapt applications to use unique network APIs for each service provider. Additionally, attracting application developers to traditional standards is challenging - they primarily contribute to open source projects.

SolutionThe DSI provides a framework to support and develop open source projects. Service provider and supplier members work together with application developers to provide client-side functionality that consistently exposes core network capabilities into real-time communications applications.

27

DSI Streamlines Network Innovation

• Existing service provider APIs offer similar functionality

• But, developer rework is required to accommodate service providers’ unique implementations

• The result:– Developer avoidance– Diluted scale– Decreased utilization

of service provider infrastructure

28

Problem Statement: Fragmented APIs

• Service providers’ unique APIs remain unchanged, but client-side abstraction normalizes the APIs

• APIs now operate consistently, reducing developer rework

• The result:– Developer adoption– Industry scale– Increased utilization

of service provider infrastructure



DSI provides a consistent mechanism to expose network APIs.

Solution: API Portability

• DSI can also provide client-side functionality

• Support and simplify interaction with network (e.g. normalize browser implementation of WebRTC)

• The result:– Complementary

functions– Simplify access to

network functionality– Additional value for

DSI and for the network



DSI libraries also provide client-side functionality.
