Ericsson | Inspirational 5G use case example

At Mobile World Congress February 2019, BT, King’s College London and Ericsson collaborate on a demo
in Ericsson’s hall showcasing how to leverage the VoLTE service for 5G. We show an Ericsson concept –the IMS data channel – which enables adding on real-time remote interaction between people and things,
alongside the current VoLTE based HD voice and video calling services. The concept builds on 3GPP
standards in combination with some WebRTC features, combining telco assets with web technologies, inorder to create flexibility in combination with operator provided features like QoS and security Learn more
how to build on today’s telephony services and bring your voice network with the inherent telecom valuesof global find and connect with the phone number, authentication, mobility, session control,
quality-of-service and security into a 5G world.

Telephony services taken to the next level with 5G
Telephony was invented in the end of the 19th century – mobile telephony was made available for themass market in the end of the 20th century – and now 5G could enable us to touch, feel and interact on acompletely new level remotely through a simple phone call.

Build on VoLTE and evolve withIMS data channel

video communication session. This will enable“touch and interact” types of use cases.

Ericsson has put a lot of thought into how
VoLTE will play an enhanced role in 5G,and not only to make basic voice calls on
5G smartphones, but how can we take thecommunication service to the next level.

Learn how to enable 5G voice to prepare
your network for this kind of concept.

Ericsson has created a concept combining
VoLTE and WebRTC technologies. This
concept we call the “IMS data channel”,
which is a separate data path within a VoLTE
session. This means you, in addition to HD
voice and video calling, can add one or several
data channels. These data channels can beused to transport any types of data for any
purpose, all synchronized with the voice andWe teamed up with our customer, the service
provider BT in the UK, who were also curious
to research how the qualities of IMS could
be used for new 5G use cases for machineto-machine as well as person-to-person
communications. BT has a lot of customers
in the enterprise sector, and they are now
looking into how IMS and 5G can benefit
these businesses and enable new enterprise

Service provider opportunity andtheir customers’ needs

use cases, particularly those requiring
real-time, critical communication service
qualities. One example is in the health sector,
which this case will describe in more detail.

Services for the benefit to society
and public health
We teamed up with our academic partner
in London, UK, King’s College London,whom through their societal engagements
has identified important needs in thehealthcare sector where mobile and wirelesscommunication could add tremendous value.
The health care industry could capture thepotentials of mobile communications in the
day-to-day challenges they face.

A use case example with real-time interaction in the health industry
Bring doctors, paramedics
and patients closer via remoteultrasound using IMS data channelover 5G
Ericsson, BT and academics at King’s CollegeLondon have teamed up to demonstrate aremote health examination over 5G using theIMS data channel concept This places theeyes, ears and the hands of a doctor alongsidea paramedic, allowing faster diagnosis anddecision making for patient care ahead ofreaching the hospital. This new concept
enables the doctor to be part of the first
responder attendance where critical diagnosis
can be the difference between life and death,and once again shows how 5G technology canenable a raft of mission critical services, andwhy 5G will deliver so much more than justenhanced mobile broadband.
Today, ambulances and paramedics
have limited capability to engage remotehealthcare professionals and therefore must

rely on the expertise of the paramedic. Few
have the training or equipment to perform
ultrasound diagnosis. If the doctor can beavailable remotely for the patient, then theright diagnosis can be performed upfront
with the right decisions on which hospitalshould the patient be transferred to, andwhat preparation is needed ahead of arrival.
This can save precious time and money for
the Health Care Provider.

The technology opportunity in
5G building on today’s telephonyservice
The current telephony service network
infrastructure VoLTE (using IP MultimediaSubsystem, IMS) which is globally deployedwith service providers, enabling voice callson LTE smartphones, will also be used toenable voice calls on 5G smartphones. The
industry could take the next step and evolve
this infrastructure and services further for
a 5G world, adding on new capabilities“BT’s 5G network, which provides
faster speeds, lower latency andenhanced reliability, combined with
IMS technology, has the potential
to deliver significant benefits to
many different industry verticals. In
this research collaboration we havedemonstrated the types of benefits
that can be provided to healthcareorganisations, and in particular
to remote health examination, byenabling secure, highly reliable, realtime communications between an
ambulance and a centralised specialist,
as required for early diagnosis andallocation to the appropriate hospital/emergency team.”— Maria Cuevas
Head of Mobile Core Networks,BT Research3Ericsson | Inspirational 5G use case examplebuilding on IMS.
BT and Ericsson have been researching theflexibility of IMS to provide not just voice
and video calling connectivity but any kindof data stream within the same session. The
IMS platform inherently provides global
find and connect with phone number,authentication, quality-of-service, mobility,security and robustness, all qualities thatare essential for real-time critical point topoint communications, such as the patient
to doctor remote interaction use case. The
low latency of 5G will enable new types ofuse cases, where real-time interaction will bepossible over long distances.
Through the capabilities delivered withIMS, the WebRTC framework allows forconfigurable data channel definitions whilst
still ensuring quality-of-service, security androbustness. Couple this with high data rates
and low latency, provided by 5G, it is easy torealize this critical health care use case andthe benefits provided to patient and healthcare experts.

Utilizing standard IMS for securing point
to point HD voice, video calling and data
communication (over the IMS data channel)
a paramedic that requires remote healthcare
assistance can connect a voice and video
call for 2-way communication. With theuse of the IMS data channel, they can now
also extend the ultrasound equipment to
the doctor for remote control and have thedoctor communicate with the patient andremotely control the hand of the paramedic
via a haptic glove. In essence, the paramedic
becomes the extension of the doctor ininteracting directly with the patient andguiding the paramedic through the diagnosis.
When the paramedic determines the patient
would benefit from an ultrasound diagnosis
the paramedic can place a video call to thecentralized ultrasound unit. The doctor,
paramedic and patient can discuss andinteract to determine next steps. Should anultrasound scan be required the paramedic
can connect the doctor to the ultrasoundmachine with the doctor being able tosee and manage the ultrasound machine
directly. With the paramedic using the haptic
glove the doctor can direct the paramedic
using the joystick control sending small
vibrations to the paramedic’s glove to direct
the ultrasound sensor, whilst the doctor
studies the image. This allows for a nonverbal, tactile interaction between doctor,
paramedic and patient. Following diagnosis,
the choice of hospital in which to send thepatient saves valuable time and ambulance
resource and allows the team receiving thepatient to prepare ahead of arrival.
In a real scenario implementation in acommercial network, it is beneficial to deliver
such a service using a network slice, in thiscase a “national health care” slice, which

These data channels can be used to transport
any types of data for any purpose, all in synchwith the voice and video communication
session. The data channels are establishedwith operator provided characteristics forthe data to be sent, in order to meet therequirements of the specific use-case when it
comes to latency, robustness and bandwidth.

Live demonstration at Mobile
World Congress 2019 – Remoteultrasound
At Mobile World Congress 2019, BT, King’s
College London and Ericsson demonstrate
how using the IMS data channel, can enablea remote ultrasound between an ambulance
and a hospital. A patient is investigatedwith ultrasound by the paramedic in theambulance, with remote support from a
doctor in a hospital far away.

“Being a civic university, serving urban
societal problem is at heart of ourresearch strategy. We have worked
with our colleagues across King’s on thevision of bringing hospital to the patient
through the power of mobile andwireless connectivity. The connectedambulance and case of remoteultrasound we are demonstrating here,
allow fast and precise diagnosis, andsave the precious time potentially spentin traffic before patient arrives to thehospital”.

would be prioritized in the network overother non-critical traffic. Within the network
slice, different bearers/data flows withdifferent characteristics can be establishedon need basis between the equipment in theambulance and the hospital. This is to makesure that communication can be done, anddata exchanged with guaranteed end userexperience. An ambulance should of course
always be given highest priority from asocietal perspective, where regulators could
also decide on different kinds of requirementon such kind of services and network priorities.

Other types of use cases
for different businesses
and enterprises
There are hundreds of other types of use
cases which could benefit from using the IMS
data channels, with exploration of these justgetting started. The health sector is just one
example. Imagine use cases such as remotesurgery, VR with collaboration, field support
with AR, drone steering, remote support.

User feedback from health careproviderFor Health Care Providers such as national
health services as well as private healthproviders, the opportunities of centralizing
experts and providing that expertise whereit’s needed, when it’s needed, further
supports the extraordinary work thatparamedics do day to day. This provides
further confidence to patients that they arereceiving world class care in more locations
than what has been possible before.
Trials with Ambulance Trusts and NHS
Healthcare professionals to see the technology
in action is the natural next step to further
optimize the solution and bring the IMS datachannel and 5G into the hands of the experts.

“The East of England Ambulance trust
is focused on delivering outstanding
care to patients and looking at ways
we can achieve better outcomes for ourcommunities. We are encouraged to see
this 5G technology that could connect
ambulances to the right clinical experts
and how this can improve outcomesfor patients through faster decision
making. Allowing us greater use of ourvaluable resources. We see techniques,
such as remote examination, as a great
example of how 5G mobile networks
and health professionals can work muchcloser together for the benefit of ourpatients and NHS staff.”— Wayne Bartlett-Syree
