Introduction
•
We all hear buzzwords or expressions
Internet for everything
All-IP services
Enhancement of home networks services
M2M services
Connectivity of home electronics between each other and with other
devices outside home etc
– Need to run across different devices and networks
–
–
–

•
•
All these buzzwords and expressions in one way or the other lead
to a concept known as ‘Home Environment Services’
One OMA enabler that can leverage other existing enablers and
offer these home-based services is CPNS
OMA TP Workshop on Home Environment Services- Honolulu 2011
What is CPNS?
• OMA CPNS enables universal access to services across a convergence of Personal Networks
and Wide Area Networks/Cellular Networks.
• OMA CPNS facilitates the service provision between two different networks that can be
interconnected by means of a Personal Network Gateway (PN GW) using a variety of mobile
and fixed devices.

Where does CPNS fit in the Home Environment?
 Customers want their devices to work
together any time, any place
CPNS meets this customer
requirement
CPNS provides the
convergence of these devices
and appliances
CPNS provides better
management of the device and
service relationship

OMA CPNS Use Cases – General
OMA CPNS has great potential in many areas, such as home
environment, Machine-to-Machine (M2M) communication, remote
personal networks etc., and is poised to help enable a wide variety of
interaction among the growing number of network connected devices and
services.
• From cars to home appliances, Internet-based services to viral content
distribution, OMA CPNS will greatly expand access capabilities to users, machines
and networks across the globe.
• OMA CPNS provides a wide range of functionality to support converged-network
services, including multimedia content delivery, end-to-end management of service
sessions, publication and discovery of services, and customization of service
characteristics based upon device capabilities.

OMA CPNS Use Cases – Multimedia Content Delivery
• An end user can watch high-quality movies on a big screen using a mobile
device serving as a gateway between a movie-streaming server via Cellular
network and home consumer electronic device via Wireless Personal Access
Network technologies.
• The mobile phone or fixed gateway provides access to the global network for
devices that only have local area connectivity (e.g. WiFi, Bluetooth).

OMA CPNS Use Cases – Multimedia Content Delivery (cont.)
• With an OMA CPNS enabled mobile phone connected to both a non-cellular
navigation device and an MP3 player with wireless personal access, a user can
simultaneously request relevant traffic updates and navigation information while
downloading music files.
• To provide multiple services simultaneously, OMA CPNS manages various factors
such as the personal network setup, service profiles, device profiles, and usage
statistics.

OMA CPNS Use Cases – In-Home Network
• OMA CPNS enables extension of Internet-based services to home appliances.
This extension enables interaction with M2M services and applications.
• An end user can access in-home appliances from outside the home using CPNS
connections between personal networks and the CPNS Server. This allows for
remote control, monitoring and content delivery.

OMA CPNS Use Cases – eHealth
• OMA CPNS provides an extension for e-health scenarios. Using a PN GW, Health
Sensors can access the CPNS server in the global network. This enables regular
monitoring and simple daily care.
• Businesses such as hospitals and pharmacies can access information from
monitoring devices attached to patients.
• Other eHealth uses could allow parents to access health sensors for their
children remotely.

OMA CPNS Architecture Diagram
• CPNS Server: Is a functional entity that provides resources to CPNS entities either in
response to requests or in a Push mode. In addition, it interacts with other external entities,
such as Content Provider Servers for the purpose of service provisioning.
• Personal Network Gateway (PN GW): A functional entity that interconnects entities that
reside in personal networks and wide area networks, instantiating a converged network that
provides CPNS services.
• Personal Network Entity (PNE): A functional entity making up a Personal Network. It may be
used either to consume or provide content and/or services, simultaneously or separately.

stretches over multiple personal networks
• PN Management
Manages personal networks and updates PN inventory
• Security
Provides the security required for CPNS when the required level of security is not
provided by the underlying technology
• Status Management
Manages the status and status information of CPNS entities, such as presence
information of PNE and PN GW -- online, offline, busy etc.
• Non-CPNS Device Proxy
Facilitates interaction between non-CPNS and CPNS devices

Market trends and main drivers for CPNS takeoff
• Market share of smart phones which can serve as a PN GW will increase
gradually. With this trend, the interoperable services between smart phone and
consumer electronic devices will become popular in both home and personal
networks.
• Data traffic on smart phones will continue to increase. Applications and content for
these smart phones will expand their target markets. With these innovations, OMA
CPNS is poised to have great impact and relevance in the growing markets.

Summary
• OMA CPNS enables full convergence between Cellular/WAN and Home Electronic
Devices
• OMA CPNS achieves better management of the device and service relationship
• OMA CPNS facilitates seamless integration of IP and non-IP networks
•Increasing demand for home network multimedia content will be the primary driver for
CPNS
• OMA CPNS working group will closely collaborate with other standards organizations
to enhance the co-existence between similar technologies, such as M2M and
DLNA/UPnP
•OMA and ETSI M2M are already collaborating on CPNS and ETSI M2M considers CPNS as
one of the enablers to be used for M2M
•OMA CPNS complements and can co-exist with M2M
•CPNS can also co-exists with DLNA and can make use of DLNA
•In particular, CPNS plays a key role when it comes to interaction with mobile handset and
non-CPNS proxy
