SDP components
Mr. Sup of ETRI showed the evolution trend on convergence
from fixed mobile convergence, telecom and IPTV convergence,
telecom and Internet, and forthcoming multiple industry domain
convergence along with M2M and IoT.
He stressed that SDP is becoming more and more important
as the focal point of the value provisioning according to his
rich experiences from 2004 of their initial production of Parlay
gateway.
He introduced ETRI SDP, which already extends the current ITU-T
Rec. to support social networking and knowledge sharing. Open
source components adopted by ETRI was also introduced.
His view expands to Future Smart SDP, whose requirements
include data-awareness, such as big data handling, and
content-oriented networking as is just started under Smart
Ubiquitous Networks (SUN) concept in ITU-T.
He is now studying modules suitable for distinct services
across multiple industry domains beyond telecommunication and
ICT.

Views from vendors
Mr. Wang of ZTE showed several successful
deployments of SDP with four domains, i.e.,
factory behind store mode, IPTV, IMS/M2M, and
cloud. The deployments ranges from China to
many other countries including multi-country
SDP model.
He concluded with requirements in standard,
which are interfaces between different SDP
subsystems (e.g., access gateway, management,
and portal), mechanisms to support distributed
deployment in different administrations and
countries, and API enhancement.

Views from vendors
Mr. Kenyoshi of NEC shed light on SDP from carrier cloud perspective in
his humble manner.
He would like to seek the path from IT-centric to ICT-centric model (i.e.,
contribution from Communication part) to increase carrier opportunities.
His view explores agricultural and ITS with protocol implications, such
as more simplicity, tolerability, and real-time sensitivity brought by
his signalling competence as SG11 vice-chairman. Unified architecture
should be considered to meet possible distinct requirements.
He referred to Japan’s consortium of M2M and cloud services in Japan
(http://www.ngm2m.jp/index.shtml).
To make it successful, carrier cloud needs deep consideration of IT,
network, and device technologies and their cooperation.
Cooperation beyond industries becomes more important as well.
In addition to the current data center simply residing over the network,
further interaction with network should be considered.
SDP modules specific to M2M need further study.

View from service provider
Mr. Budzisz of Telekomunikacja Polska introduced
their valuable experiences of IMS
deployment. He reminded us of the importance
of speed, cost, and interoperability for service
deployment.
Some services are already available such as highdefinition voice and parallel ringing.
On hardware, the latest IMS implementation
allows more compact packaging of multiple
functional elements (e.g., HSS and several
CSCFs) into a single ATC chassis.
Further standards may be necessary when rich
communication services extends to multiple
operators.
