The document discusses Xura's RCS API Gateway, which enables network operators to leverage their existing assets to create innovative IP services for RCS. The RCS API Gateway connects RCS core components like IMS in a carrier-grade way using web APIs, eliminating the need for developers to understand telco infrastructure. This allows network operators to develop new monetizable RCS services easily by integrating with the core network through the standardized RCS UNI interface, avoiding traditional overhead and allowing services to be deployed quickly.

Fact sheet
Open the Door to RCS Monetization Opportunities
Xura’s RCS API Gateway enables network operators to leverage their existing assets and
strengths to create innovative services. The next generation of blockbuster IP enabled
services will most likely be enabled by a combination of network operator assets plus
chatbots, 3rd party applications or mash-ups with existing internet services.
The evolution to a rich communications ecosystem involves many key components
including the IMS infrastructure and standards-based user interfaces. The RCS API
Gateway connects these components in a carrier grade manner but with the simplicity
enabled by web based APIs.

The API approach eliminates the need for developers to become telco infrastructure
experts and understand the complexities of how IMS, OMA messaging or SIP works.
Functional RCS complexities are enabled by web-based APIs using successful
development paradigms widely used by internet firms and large enterprises.
Xura’s RCS API Gateway
The RCS API Gateway enables a network operator to easily develop, or enable, new
monetizable RCS services. Integration with the core network is based on the RCS User to
Network Interface or UNI, avoiding the overhead, delays and costs of traditional approaches:
–– Services are subject to the same controls as RCS subscribers: security, policy, interception
–– RCS UNI is a very well understood and tested interface, independent from the core
–– Existing IMS and RCS servers are used, with no ad-hoc configuration
–– No requirements over provisioning or other OSS/BSS systems
–– A subscriber just needs an RCS enabled terminal to access applications and services,
no extra software or specific configuration is needed

2. The streamlined UNI allows the relationship a network operator has with developers
to become more “internet-like” than the traditional model that required long periods of
development and testing. The bulk of network integration is enabled by the RCS API
Gateway which means using RCS UNI eliminates the need for complete testing cycles
for each application. As a result, service providers remain fully in control and existing
procedures and systems can be effectively managed and re-used.
This lightweight network integration enables services to be deployed easily for API stores,
bot stores or even for pilots and trials. With minimal overhead, services are enriched with
genuinely useful functionality allowing the network operator to explore business models
and developer engagements before a full launch.
RCS API Capabilities
–– Can be deployed In-Network or Cloud
–– Runs on standard Linux Servers
–– RCS Blackbird certified. Supports Crane as well
–– Supports REST API, Web services
RCS API Benefits
–– Implemented as a virtual client. Easy integration with existing network operator core
network through RCS UNI interface
–– Increased security – IP services subjected to same controls as RCS subscribers
–– No special apps, software or provisioning required
–– High ROI - monetize RCS with innovative IP services including “RCS App Stores”
and chatbots for customer services, in-chat apps, or innovative contextual
advertisement experiences
–– Simplifies the creation of alternative web based access to RCS communications
and services.
Leading Innovation
Xura has held patents in the gateway technology since 2010 that enable IP messaging
to interact with and take advantage of core network functionality in the same manner as
chatbot interactions.
The Xura RCS API Gateway won an award at the GSMA RCS DevChallenge in 2011,
continuing to innovate since then, which includes features such as file transfer
(audios, pics) and geolocation push to enrich potential use cases for plain text chatbots.
