Biggest challenge for ICT-enabled construction in the manufacturing
industry: system integration
 Numerous ICT-enabled systems,
difficult to collaborate and integrate
ICT-enabled construction varies according
to manufacturing enterprises.
Take a large manufacturing company X as
an example. Company X has 7 business

Office collaboration and service
integration urgently await to be
achieved in a convergent office
solution.
Overall solution architecture: bearing office collaboration with
one network and integrating service experience with eSDK
③eSDK business middleware
The eSDK server is deployed in the
equipment room to offer the
interfaces for the following
functions to business systems: UC
service invoking, authentication,
message push, electronic name
card, and personal settings.

Enterprise-grade core voice gateways
are responsible for cross-region
scheduling and call control, and are
deployed in a distributed manner to
enable network-wide multi-service
planning and ONLY.

②IP and TDM compatibility
Huawei U19/29 series IP PBXs are used
to support No.7 signaling (not
supported by Cisco devices) and
interoperate with legacy PBXs,
enabling smooth evolution from the
TDM system to the IP voice system
and maximizing customer investments.
Collaboration difficulty and operation complexity
 Difficult to use the isolated
communication means
The communication means are mutually
separated: user interfaces are inconsistent and
functions are not interoperable.
Different communication means demand
different systems, contact numbers, and
operation processes.
 Difficult to reach the person in a timely
manner
One employee has 6+ contact numbers that
are mutually isolated and difficult to remember.
Users have to dial different contact numbers
and find the appropriate one when calling an
employee who is out of the office.
Company X has 6+ communication means,
involving communication systems from diverse
vendors.

Conflict: Company X wants to deploy a convergent conferencing
and collaborative office system, but legacy systems cannot
interoperate with the new system.
Costs:
Retaining the legacy
analog phone system
that accommodates
130,000 users
Adding an IP service
system that accommodates
130,000 users
Two networks, resulting in a tremendous waste
in O&M and investment

① A UC client requests authentication.
②③ The UC platform delegates the CA
center to perform authentication.
④ The UC server sends a token to the
