... before W3C, I've been involved in 3GPP, IETF, OMA
... want to share today our thoughts how telecos can work with
Web technologies
... We still have some unclear areas how vendors and telcos can
work in W3C
Ryoichi Kawada: KDDI, visiting researcher in Keio University
InGeeKim: SK telecom (in Korea)
RuinanSun: Huawei AC Rep
GangLiang: [present slides]
... both operators and network equipment providers have gotten
involved in W3C
... that's a clear sign they see the importance of the Web to
their business
... internet economy extends to the real economy
... everything is moving to digital
... Web technology have been and will be widely used
everywhere, every time
... more and more people use their mobile to access the
network
... I think this will be the main trend in the future
... Web technologies have affected telecoms
... social networks provide services similar to telecoms, e.g.
audio/video call, file transfer, messaging
... telcos revenues have been falling year over year
... (diagrams illustrating how OTT are increasing while
revenues of telecos are decreasing)
... the global mobile 3G subscribers is growing very
quickly
... up from 1.1B to 1.59B last year (globally)
... another trend is the increasing share of smartphone usage,
with their underlying platforms (e.g. android, tizen)
... increasingly mobile phones are used to access
internet
... mobile traffic represents 10% of total internet
traffic
... openness is very important to telecom — a lot of operators
open their ecosystem to 3rd parties, users
... OMA has developed RESTful APIs to provide standards
interfaces for that
... including an open connection manager API, and a Web Runtime
API
... these make it easier for Web developers to get access to
these services
... European operators and some from China have opened up their
platforms using these APIs
... Operators have also telecom quality of service
imperatives
... they have to manage how bandwidth is spread across users
depending on theirs needs
... via load balancing, congestion control
... What are the advantages of telecom they can use?
... a large base of subscribers
... mobility is extremely popular
... we have already an open platform that can be reused and
offered via APIs
... QoS is another asset
... The topic we wanted to raise today are:
... * how telecom should get involved in W3C?
... almost all mobile companies, incl network vendors and
operators, have to bring influence in requirements
... we need browsers to support considerations around service
priority, congestion control, etc
... W3C has ongoing important work relevant to us, WebRTC,
WebTV; it's important that operators look at what kind of APIs
they can bring to the table
Dom: Payments sounds like a pretty good match for operators
Qiuling: not only operators can provide service here; internet companies have a strong role
Dom: clearly operators will be in
a competition with other systems
... they have to rely on their assets (strong billing system,
large subscriber base)
<Ruinan> taobao pay
<BoYang> www.taobao.com
Qiugling: taobaoo is a very
popular internet based solution in China
... will be difficult for operators to compete with it
LingCheng: operators have a
strong system to charge on mobile
... Another advantage in China, China operators have a strong
advantage in their connection with banks
... Either China Mobile or China Unicom have an agreement with
a bank to enable NFC-based payment
BoYang: we can enable payments
via cell phone without a credit card
... we require developers to be certified before they can
access this payment system
... Part of our difficulties is actually to get agreements with
each or every bank
... we don't have an advantage in this
Ruinan: it's hard for operators
to support many business model
... they would need to use very different billing systems
DKA: in Europe, operators are
regulated into what they can use their billing system to pay
for
... forbidden to e.g. pay a cup of coffee
... there were even worries about extending it to e.g. mobile
apps
... Paypal can do what ever they want
... We have a program deployed in Spain on Google Market and
Microsoft app store, and in UK on Microsoft app store
... you can pay with your mobile phone number in a very
seamless manner
... (they don't have to enter their PIN codes)
... available for low cost operations
... program also available in Mexico
... Google e.g. was very eager to get access to the operator
system payment, as this removes a barrier to people buying
apps
Qiuling: how much changes were needed in your billing system to enable this?
DKA: some, but mostly small, and mostly in the middleware system
Tatsuy_Sony: did that need to ship with special software?
DKA: the client is shipped by
Google / Microsoft
... and then there is server integration
... currently not standardized; this is close to what GSMA had
suggested in OneAPI, but we haven't seen much commercial
adoption of that API
... Standardization would be useful, but most of the time, the
API being used is imposed by the partner (e.g. Google)
RyochiKawada: can you clarify the goals of listing operator advantages here? is it for people to join W3C?
GangLiang: goals is to understand what we come in the market with and how W3C can help us use these advantages
DKA: I think the perspective
you've presented is closer to the "traditional" view of
operators business
... One thing that Telefonica Digital is trying to push another
approach to this
... e.g. our collaboration with Firefox on FirefoxOS
... or TokBox that uses WebRTC
... Telecom companies are shifting their model to incorporate
more internet services
... and/or combine them with telco services
... For these, WebRTC, SysApps, WebApps, Web Payments, Data on
the Web are very important
Ruinan: so the idea is to reuse
internet technologies to provide them the end user
... what is the benefit to integrate them with existing
systems?
DKA: we have an app available in the UK, soon in Argentina, called Tugo
<BoYang> Tugo?
DKA: it's a voip application that
incorporates messaging and voice
... it uses WebRTC
... but it's not a pure voip solution : it integrates in our
corenetwork
... it uses the internet to integrate to my operator network
even when I'm not connected to my operator network
... applicable to roaming situations, underground
disconnectivity, multi-devices usage
... an additional advantage is that it even reduces our
bandwidth usage
... it's an example of hybrid application of teleco/internet
services
<BoYang> same fee for voip and cs call?
DKA: we want to extend that to other examples (e.g. video)
Dom: this shows that phone number is also a big assets operaetors have
LingChen: huge opportunity here
for operators
... IMS gateway to WebRTC
Ruinan: W3C has many internet
players, but harder to find momentum behind operators
proposals
... Push API has been proposed by operators but have lacked
adoption
DKA: Firefox will implement
it
... hopefully with the PAG now being resolved, others will
follow suite
Dom: Push API is a pretty
advantage for operators if they manage to bring other players
in this space
... Safari has been shipping a similar API for their desktop
which shows the need is broader than just telecos
GangLiang: how would you deploy Push on your network? (@@@ not sure)
DKA: big debate on the future of
RCS; lots of disagreement in this space
... Telefonica's approach is to have a foot in both camps
... We have tugo for WebRTC, and Joyn for RCS
Ruinan: W3C focus has been on the
client side
... Operators have traditionally focused on the network side of
standardization
... For instance, Push API is only defining the API used by the
browser, not what's the underlying system used to Push
DKA: by design; it's something
configurable and get configured when the device gets
shipped
... it's a user configurable
LingChen: W3C works on the
API
... IETF looks at the protocol layer
... Assuming W3C stays focused on APIs, what is the opportunity
for operators to look at that layer?
BoYang: we need a unified API
across vendors
... it's important for us to have compatibility across
browsers
... we don't care about the details of the API, as long as it
matches our requirements
... (for WebRTC)
LingChen: Imagine Baidu develops
an OTT application on top of Firefox
... how would you compete with them with a Firefox app?
BoYang: we would let the market
choose what work best for users
... Even if Baidu does it, that doesn't mean we should not
provide a solution
LingChen: I guess the key is for operators is to find what unique advantages operators have that they can push into W3C work
BoYang: we do want to make the
best app out there
... but it's clear we can't assume we will win by being the
only providers
... it used to be geolocation was something only operators
could provide via cell towers
... now there are many other ways to get the same
Qiuling: operators are no longer
the only one in position to provide a service
... they have to compete on the market
BoYang: for instance, we can provide a much better customer service
Qiuling: but this becomes harder are things are moving to the service layer
Ruinan: internet companies have shown their abilities to deploy new services much more quickly
DKA: that's why operators have
moving to similar approaches as OTT companies
... e.g. Telefonica digital
... although plugging into legacy systems remain always long
and difficult$
... but once you've plugged it, it opens a lot of new
possibilities in terms of services and applications
Ryoichi: I think operators are more focused on the network side
KepengLi: operators can also
integrate with existing OTT services to create new business
opps
... we discussed advantages in payments
... others include possibly geolocation; Web identity
... part of the discussions is what advantages we can exploit
more quickly
Tatsuya: I think we need to look
at this at a higher level
... there are two layers we can look at
... @@@
... and APIs to access hardware feature
... Should W3C also focus on APIs that build on operators
advantage?
KepengLi: the TTML Working Group is looking at a simplified profile for mobile
Dom: My goal with the Web and Mobile IG was to enable that kind of discussion
