How to achieve the convergence
between Telecom and Internet
What we need from operator side
IP based network Architecture to provide telecom service
capabilities, such as Voice, Video, MMS, SMS, Presence,
address book, Conference, Charging etc
Open APIs for different service capabilities, such as Parlay
APIs, Restful APIs
Authorization, authentication, security ,and management
functions for the apps, third party service provider, and
developers
Operators may benefit from IMS/NGN and SDP
technologies
IMS/NGN is an IP based network, which provides various
service capabilities and carrier class operating and
management functions
SDP is an platform to support the open APIs, and app
developing environment etc

Functional Architecture of wIMS (2/2)
The main functions of wIMS include:
Application Access Gateway (AAG):
Authentication & Authorization （SSL、HTTP basic auth）
Service Virtualization（Service discovery and publishing）
Data protection (Digital Signature, XML Firewall)
Service Composition Environment (SCE) :
Different service capabilities may be composed to be the new
service capability through this function
Open Service Gateway (OSG):
Interface with service enablers and networks
Protocol transformation
APIs
Progress of IMS deployment in China
Mobile
The global largest commercial IMS system has
been developed in China Mobile
Scale and Status
•IMS
network were deployed in the
whole country at 2010，and could
be able to support 20M+ users
•At 2011, China Mobile also
deployed several IMS service
enablers, such as MMTEL,
converged IP Centrex, PGM etc.
Now China Mobile has around 8M+
IMS subscribers
•The prototype of wIMS (wIMS1.0)
was also deployed at 2011
Until AUG 2011
Completed
Under construction
wIMS1.0 is the prototype of wIMS
wIMS1.0 is deployed in China Mobile to support
the open APIs of Voice, SMS and MMS
Similar as a SDP without SCE
Support the basic voice and message capability, such as Click
to Dial, SMS, MMS etc
Support the RESTful API, it’s easy to use for the internet app
developers
Use Case 1:
Enterprise Conference Mobile widget
Alex is on a business trip.
He needs to book a
conference between Bob
and Nick for emergency
The conference goes on
very well.
When the last one leave,
the conference is over
Alex use his mobile , pad or
pc to run the app ,login into
the OA and Initiate a
conference quest with Bob
and Nick
The AS calls all the contact
info listed in the API
parameters. Mobile, POTS
and PC client are all
supported
The
APP
Invoke
the
Conf
APIs
Use Case 2:
Internet Business Advertisement
Bob wants to rent out his
apartment. put this information
on the Facebook with a clickclicktoto-dial name card to hide his
mobile number
Nancy browses the
information, ,and wants to rent
Bob’
Bob’s apartment. She clicks
the icon to make a call. Here
the SMS API can also be used
for security
When Bob answer the call,
Nancy and Bob may talk to
each other
Firstly AS calls Nancy, the IVR is
coming to tell Nancy to wait for
Bob joining in
The
APP
Invoke
the
CTD
APIs
Thanks!
