5G offers communication service providers an unprecedented opportunity
to enhance their position in the value chain and tap into new revenue
streams in a variety of industry verticals. A successful transition will require
business support systems (BSS) that are evolved to fit the 5G economy.
JAN FRIMAN,
MICHAEL NILSSON,
ELISABETH MUELLER
The rapidly expanding Internet of Things
(IoT) and all the new capabilities available
in 5G have opened up a wealth of opportunities
for communication service providers (CSPs)
beyond their traditional markets, particularly
in verticals such as automotive, health care,
agriculture, energy and manufacturing.
To monetize them, CSPs will need to meet
the expectations of a broader range
of stakeholders and be able to handle
complex ecosystems.
■ One of the primary roles of business support
systems (BSS) is to manage a CSP’s relationships
with its stakeholders by keeping track of
agreements, handling orders, generating reports,
sending invoices and so on. In the past, these
stakeholders were generally limited to consumers,
resellers, partners and suppliers. In the 5G/IoT
business context, though, more complex
ecosystems are arising that BSS must evolve to
support. To do so, the requirements of a larger,
more diverse group of stakeholders must be taken
5G BSS:

into account, and mechanisms must be established
to manage the relationships between them.
Examplesofnewstakeholdergroupsthatneed
tobeconsideredinthe5G/IoTbusinesscontext
include:
❭ Enterprises and industry verticals that require
solutions beyond telecoms
❭ New types of suppliers such as IoT device
providers and suppliers of eSIM (embedded
SIM) and related technologies
❭ Platform providers that specialize in specific IoT
or edge clusters or groups of use cases such as
massive and broadband IoT platforms, industrial
IoT platforms and content data networks
❭ Integrators that specialize in specific verticals
such as asset management, mission-critical
services or automotive that combine
capabilities from multiple stakeholders to
address consumer needs.
