Why 5G Slicing SLA Needs to Be Standardized?
Over the pas t year, 5G ne twork s l i c ing has
m a d e a s i g n i f i c a n t i m p a c t i n t h e t e l e c o m
indus t ry. Opera to rs and equ ipment vendors
unders tand the t remendous benef i ts o ffered
by network slicing, and are determined to take
full advantage. Consequently, an array of white
papers have been released, which expand on
network slicing technologies and architectures
and delve deep into its application benchmarks.
These white papers serve as valuable references
for the fur ther developing of network s l ic ing;
however, the technica l deta i ls conveyed are
quite complex and difficult for industry customers
to fol low, and the industry-specif ic use cases
provided do not lend themselves well to simple
application in other f ields by service suppliers
and device vendors. As such, this paper centers
on c lass i fy ing indust ry SLA requ i rements a t
different levels, aligning varied service demands
with specific technology implementation.
Clear SLA requirements and levels are crucial
to both network sl ic ing service providers and
consumers, so that both parties can jointly plan

an appropriate set of network capabi l i t ies for
certain service scenarios. In order to achieve
th is , we need to recogn ize and unrave l the
following issues:
• Industry players do not have a common
understanding of network slicing.
While a batch of industry applications have been
verified on SA networks, industry players suffer
f rom a lack of knowledge regard ing network
slicing capabilities. As a result, they are unclear
abou t how to pack such capab i l i t i es i n to a
network slice suitable for their industry sectors
and how to purchase a we l l -des igned s l ice ,
let a lone see the business opportuni t ies and
benefits that go along with network slicing.
• Operators do not sufficiently involve
industry partners when defining the SLA.
A well-rounded SLA framework must be able to
support all professional applications in different
industry segments, and i t cannot be def ined
by operators alone. Joint efforts with industry
customers, especia l ly leading enterpr ises in
each domain, are indispensable to formulate
01Page

a comprehens i ve , c l ea r, and adap t i ve SLA
framework.
• Current slice classification and SLA
levels are not ideal for efficient slice
management.
Network capabi l i t ies need to be orchestrated
with fine-grained control for flexible combination,
but too f ine a granular i ty wi l l c r ipp le s l ic ing
management. The operat ional complexity and
service requirement diversity must be balanced
v ia c lear SLA speci f icat ions and streaml ined
service quality management processes, so that
both service providers and consumers can seek
a cost-effective and beneficial slicing solution.
Such a solution will be the product of continuous
verification and iteration in the market.
As such, research on SLA levels for 5G network
slicing is of vital importance, as it will facilitate
t he ope ra t i on and managemen t o f ne two rk
slicing and benefit both operators and industry
players. To be specific:
• Appropriate SLA levels help industry
customers to understand and leverage
network slices.
Well-defined SLA metrics will effectively reflect
serv ice types and di fferences. Standard SLA
levels combined wi th these metr ics can help
industry customers efficiently select ideal slices
which f i t into industry characterist ics, thereby
avo id ing unnecessary commun ica t ions w i th
operators or service providers. Industr ies can
reap the benefits provided by 5G technologies
and applications in no time.
• Standard SLA enables operators to better
serve industries.
T h r e e m a i n b e n e f i t s e x i s t i n t h i s c o n t e x t :
First, by standardizing the SLA, operators wil l
gain valuable insights into the 5G application
requirements of different industries, based on
which operators can tai lor sl ices favorable to
most applicable fields. In addition, the standard
SLA framework wil l contribute to lower OPEX.
Opera to rs can p rov ide d i f f e ren t quo tes fo r
services at different SLA levels and negotiate
s e r v i c e p r i c e s a n d a s s u r a n c e l e v e l s w i t h
customers via a communication platform, while
network sl ices can be accurately and f lexibly
customized with cost-beneficial O&M. Last but
not least, the SLA framework helps yield higher
s l i ce serv ice qua l i ty by o f fe r ing sys temat ic ,
rat ional cr i ter ia to evaluate di fferent types of
sl ices. Consequently, operators can precisely
monitor and control services on each slice.
• SLA levels serve as valid reference for
industry authority decision-making.
Security is a common concern among industries

psychologist. He proposed a model for analyzing
innate human needs which were depicted as
hierarchical levels within a pyramid. Individuals
must sat is fy needs at the lower leve l o f the
hierarchy before progressing to those higher up,
and this model has become a general-purpose
theory used to c lass i fy needs. Accord ing to
Mas low 's mode l , t he indus t ry requ i rements
on 5G ne tworks can a lso be c lass i f i ed in to
a h i e ra r chy o f needs . F rom bo t t om to t op ,
these are: deterministic services, security and
trustworthiness, and self-management.
• Deterministic services
D i f f e r e n t u s e r g r o u p s i m p o s e d i f f e r e n t
requ i rements on bandwid th , la tency, packet
loss rate, jitter, service availability, and service
provisioning efficiency. To ensure deterministic
services for a certain user group, in addit ion
to SLA assurance , d i f fe ren t ia ted res t r i c t ion
measures such as l imit ing the traff ic rate for
po in t - to-po in t serv ice users may need to be
taken. In addit ion, AI- infused edge computing
02and posit ioning must be provided from end to
end for available services.
• Security and trustworthiness
Some industr ies have str ingent requirements
on network secur i ty and re l iab i l i ty, and may
demand a dedicated logical network in order to
secure their services with isolated resources.
They may further require data be encrypted and
authenticated, preventing services on their slices
from being tampered with. Such security rules
will be incorporated into the service systems of
industry customers, making these systems more
intelligent and adaptive.
• Self-management
Industry customers increasingly monitor KPIs,
such as latency and bandwidth, and configure
network sl ices by themselves. They may even
expect to use their own network devices, such as
core gateways and edge computing equipment.

Latency
In our survey, we selected bandwidth and latency as two major dimensions to reflect the deterministic
levels of services. The tests conducted in Zhejiang Unicom's 5G slicing project at a medical community
coincided with our selection, as the results showed that these two factors result in the greatest impact
on user experience. The table below lists the bandwidth and latency for different experiences with
image zoom and rotation in 3D image reconstruction.
Experience Bandwidth (Mbit/s) Latency (ms)
Smooth, with no noticeable latency 20 10
Slight latency 10 110
Obvious latency 3 179
The requirements for security and trustworthiness are primarily fulf i l led by isolating resources at
different levels, and those for self-management can be determined by the management capabilities
of industry customers. As the layered model becomes more widely applied, more dimensions can be
introduced to categorize and evaluate SLA needs.

03SLA Palette for 5G Network Slicing
To help industry customers easily understand SLA levels and match them with their service needs, we
have defined a palette to illustrate 5G slicing SLA requirements.
The requirements for bandwidth, latency, security and trustworthiness, and self-management are
arranged into levels B1-B5, T1-T5, S1-S2, and M1-M3, respectively. Customers can select levels to set
up an SLA for their services; for example, the SLA requirements for video monitoring at a power grid
can be a combination of B3, T2, S1, and M3.

We have used this palette to conduct surveys in three major industries — healthcare, manufacturing,
and energy. The following sections illustrate the SLA levels in these fields.
SLA Palette for 5G Network Slicing05Page
04Healthcare Slices and SLA Levels
The SLA requirements of the healthcare industry apply to three types of slicing: the diagnosis guidance
slice based on real-time interaction using images and videos, the remote operation slice based on
force feedback, and the monitoring and nursing slice based on wireless collection.

• Diagnosis guidance slice based on real-

(B3, T2, S1, and M1)
T h i s t y p e o f s l i c e p r o v i d e s s e r v i c e s s u c h

demonst ra t ions , and main ly t ransmi ts v ideo
streams and examination images in real time.
The user bandwidth level is B3 (20–50 Mbit/s).
Services such as real-time teleconsultations and
surgery demonstrations rely on the transmission
of HD videos, and some services also require the
backhaul of medical operation images from the
patient's side. As such, network bandwidth must
reach 10–30 Mbit /s. In terms of f i le transfers
such as pathological sections, a 1 GB fi le can
be transferred within 3 minutes in cases where
bandwidth reaches 50 Mbit/s and the theoretical
transmission rate is 6.25 MB/s.
The latency level is T2 (20–50 ms). Video stream
appl icat ions, such as te leconsul tat ions, may
experience latency at the following three points.
First, stream pushing: Latency occurs when the
col lected audio and v ideo data is processed
and encoded. Second, st ream pushing using
a specif ied streaming media protocol: Latency
occurs due to the impact of a used protocol
on a certain network condit ion. Third, stream
pu l l ing: Latency occurs when the aud io and
video data stream is pul led and decoded. As
such, live streams are not sensitive to network
la tency. However, te leconsu l ta t ion invo lves
mutual interaction, and excessively high latency
wil l severely impact the interactive experience
offered. Consequently, a network latency of less
than 50 ms is recommended for teleconsultation
services.
The iso la t ion leve l i s S1 ( log ica l i so la t ion) .
As teleconsultat ion does not typical ly involve
s e n s i t i v e d a t a , o n l y l o g i c a l i s o l a t i o n i s
performed, and network resources can be shared
with other users and services.
The management level is M1 (visualized). Users
in the hea l thcare indust ry are not equ ipped
w i th p ro fess iona l know ledge o f SLA-based
slicing. According to their feedback, they expect
telecom operators to be responsible for s l ice
management, while hospitals can access slice
status, user information, and SLA reports.
• Remote operation slice based on force
feedback (B2, T5, S2, and M1)
This type of s l ice prov ides serv ices such as
remote surgery and ultrasonic examination, and
primarily transmits data such as patient surgery
i m a g e s , B - m o d e u l t r a s o n i c p r o b e i m a g e s ,
control signals from operation rockers, and force
feedback tactile signals.
The user bandwidth level is B2 (10–20 Mbi t /
s). As low-latency applications such as remote
surgery and B-mode u l t rason ic examinat ion
require real-time backhaul of images of patients
and p robes , ne twork bandwid th mus t reach
approximately 20 Mbit/s to transmit stutter-free
video streams.
The latency level is T5 (less than 5 ms). Remote
surgery is currently performed based on human-
mach ine in te rac t ion . Wi th the he lp o f v ideo
backhaul and medical robots, medical experts
remotely assist onsite doctors in planning and
implementation before and during a surgery. As
human-machine interaction can lead to latency
with a human's response, the network latency
Healthcare Slices and SLA Levels07Page
requirements should be lowered. Upon receiving
an onsite doctor's confirmation, a remote expert
per forms the next s tep, wi th latency ranging
from 10 ms to 100 ms. However, actual remote
surgery is performed based on machine-machine
interaction. Specifically, a remote expert directly
opera tes a robo t i c a rm to pe r fo rm surgery.
This type of surgery requires network latency
to be less than 5 ms to ensure synchronized
operations at the local and remote ends.
The isolation level is S2 (physical isolation). This
type of sl ice must be physical ly isolated from
other services and requires exclusive resources
(E2E hard slice) to prevent surgery from being
affected by factors such as external network
f l uc tua t ion . The i so la t i on l eve l mus t be S2
(physical isolation) to ensure network security
and high performance.
The management level is M1 (visualized). Users
in the hea l thcare indust ry are not equ ipped
w i th p ro fess iona l know ledge o f SLA-based
slicing. According to their feedback, they expect
telecom operators to be responsible for s l ice
management, while hospitals can access slice
status, user information, and SLA reports.
• Monitoring and nursing slice based on
wireless collection (B1, T1, S1, and M1)
This type of s l ice prov ides serv ices such as
wireless monitor ing and mobi le ward rounds,
and mainly transmits data such as patients' vital
signs, electronic medical records, and doctors'
orders.
The user bandwidth level is B1 (1–10 Mbit/s). B1
will suffice as multi-terminal access applications
are s imi la r to IoT connect ions. Add i t iona l ly,
the serv ice data does not inc lude images or
videos, the data volume is small, and the data
transmission is infrequent.
The la tency leve l i s T1 (50–100 ms) . Mul t i -
terminal access applications are used to monitor
da ta such as pat ien ts ' v i ta l s igns . The on ly
requirement is to ensure that the data can be
transmitted to medical personnel. As such, these
services are insensitive to latency.
The isolation level is S1 (logical isolation). Data
transmission of information such as vital signs
and patho logy requi res log ica l iso la t ion and
secure encryption authentication (slice resources
can be shared).
The management level is M1 (visualized). Users
in the hea l thcare indust ry are not equ ipped

05Manufacturing Slices and SLA Levels
Based on SLA requirements, manufactur ing sl ices can be high-upl ink-bandwidth auxi l iary non-
production slices, massive-information-based auxiliary production slices, and high-reliability precise-
control core production slices.

This type of slice applies in the transmission of big video data, and predominantly involves HD video
monitoring and HD video quality monitoring. It features:
Manufacturing Slices and SLA Levels09Page
Bandwidth level B3 (20–50 Mbit/s): As 4K video
monitor ing is widely used in enterpr ises, and
there are currently no requirements for 8K video
monitoring, the maximum bandwidth is 40 Mbit/s.
La tency leve l T2 (20–50 ms) : The to le rab le
latency is approximately 50 ms.
Isolat ion level S1 ( logical isolat ion): As video
monitoring slices do not involve sensitive data
relat ing to their corresponding services, only

services.
Management level M1 (visualized): Enterprise
customers are unfamiliar with slicing SLA, and
instead require the v iewing of s l ice statuses
and user information, in addition to SLA reports.
Such customers have operators manage slices,
rather than util izing self-management and self-
operation.
• Massive-information-based auxiliary
production slices (B1, T2, S1, and M1)
This type of slice applies in massive connection
scenar ios, and predominant ly involves basic
device information collection and environment
monitoring. It features:
Bandwidth level B1 (1–10 Mbi t /s) : In factory
environment monitoring and device information
collection, the uplink and downlink bandwidths of
a single node are less than 200 kbit/s. As only a
small amount of control data is sent to collection
devices in the downlink, bandwidth requirements
are not high.
Latency level T2 (20–50 ms). System control

Isolat ion level S1 ( logical isolat ion): As video

This type o f s l i ce app l ies in remote cont ro l
scenarios, and predominantly involves control
data transmission. It features:
Bandwid th leve l B1 (1–10 Mbi t /s ) : Bo th the

leakage, or damage to ensure data integrity and
stability.
Management level M2 (manageable): Enterprise
customers can modify and terminate services,
manage UE lifecycles, and perform simple fault

06Electric Power Slices and SLA Levels
The SLA requirements of the electric power industry apply to three types of slices: inspection slice
based on HD videos, power grid control slice based on low latency, and monitoring slice based on
wireless collection.

• Inspection slice based on HD videos (B3, T2, S1, and M3)
This type of sl ice mainly provides big video services, and appl ies to scenarios such as mobi le
inspection of power transmission lines, comprehensive video monitoring of power distribution rooms,
robot inspection of substations, and AR/VR-based intelligent inspection.
Electric Power Slices and SLA Levels11Page
The user bandwidth level is B3 (20–50 Mbit/s).
The required bandwidth var ies depending on
the type of video. For example, AR inspection
requires at least 30 Mbit /s bandwidth, drone/
robo t i nspec t i on requ i res a t l eas t 2 Mb i t / s
bandwidth, and video monitoring requires 4–10
Mbit/s bandwidth.
The latency level is T2 (20–50 ms). Inspection
applications do not have high requirements on
latency, with the latency of AR inspection less
than 50 ms, that of drone/robot inspection less
than 300 ms, and that of video monitoring less
than 200 ms.
The iso la t ion leve l i s S1 ( log ica l i so la t ion) .
Power grid appl icat ions are used for services
in the production control area and management
information area. Video monitoring applications
a r e u s e d f o r s e r v i c e s i n t h e m a n a g e m e n t
in fo rmat ion a rea and need to be phys ica l l y
i s o l a t e d f r o m p u b l i c n e t w o r k s e r v i c e s ,
applications of other industries, and services in
the power production control area. In addition,
services in the product ion management zone
(security zone III) need to be logically isolated
from those in the information management zone
(security zone IV) in the same area. Considering
the balance between service requirements and
network construction costs, it is recommended
that the 5G core network and bearer network
implement physical isolation, and that the RAN
implement the resource preemption mechanism
based on priority scheduling to achieve logical
isolation.
The management level is M3 (operable). Electric
power inspection applications involve mult iple
areas, and self-defined user group management,
new service rollout and commissioning, self-help
troubleshooting, and access permission control
are general ly required. As such, management
achieves the M3 level (operable).
• Power grid control slice based on low
latency (B1, T3, S2, and M3)
This type of slice includes intelligent distributed
power distr ibut ion automation, electr ical load
requirement response, and distr ibuted energy
control.
The per-user bandwidth level is B1 (1–10 Mbit/s).
Control data is mostly instruction data, and the
data bandwidth is approximately 2 Mbit/s.
The la tency leve l i s T3 (10–20 ms) , as the
latency of differential protection cannot exceed
15 ms. With the wide application of intell igent
distributed power distribution network terminals,
more distributed point-to-point connections will
emerge, and more local control and linkage with
the main network wil l be required. In addition,
millisecond-level latency will be required.
The isolat ion level is S2 (physical isolat ion).
A p p l i c a t i o n s s u c h a s p o w e r d i s t r i b u t i o n
automation and precise load control are used
for serv ices in the power product ion cont ro l
area, and these need to be physically isolated
f rom publ ic network serv ices, app l ica t ion o f
o ther indus t r ies , and serv ices in the power
management area. In addition, services in the
real- t ime control zone (secur i ty zone I) need
to be logically isolated from those in the non-
c o n t r o l p r o d u c t i o n z o n e ( s e c u r i t y z o n e I I )
in the same area . E2E phys ica l i so la t ion is
recommended. That is, in addition to the 5G core
network and bearer network, the RAN network
implements the resource block (RB) reservation
mechanism to achieve physical isolation.

T h e m a n a g e m e n t l e v e l i s M 3 ( o p e r a b l e ) .
The electr ic power industry involves mult ip le
provincial and municipal companies. Through
open APIs, users can take advantage of self-

• Monitoring slice based on wireless
collection (B1, T1, S1, and M3)
This type of slice applies to scenarios such as
electr ic i ty consumption information col lect ion
and power distribution network status monitoring.
The collected content mainly includes basic data
and images, and requires massive connectivity.
The per-user bandwidth level is B1 (1–10 Mbit/
s). Most control data and monitoring data to be
transmitted consist of small data packets, and
1–100 bit/s bandwidth is required for a single
data transmission.
T h e l a t e n c y l e v e l i s T 1 ( 5 0 – 1 0 0 m s ) . T h e
moni tor ing on the device running status and
running environment is intended to improve the
management of key devices and facilities, while
the required latency ranges from hundreds of
milliseconds to seconds.

area, and need to be physical ly isolated from
publ ic network services, appl icat ions of other
industries, and services in the power production
control area. In addit ion, services in securi ty
zone III need to be logically isolated from those
in security zone IV in the same area. Considering
the balance between service requirements and
network construction costs, it is recommended
that the 5G core network and bearer network
implement physical isolation, and that the RAN
network implement the resource preempt ion
mechan ism based on p r io r i t y schedu l ing to
achieve logical isolation.
The management leve l is M3 (operab le) : As
wireless collection applications involve a large
number of power terminals and devices, self-

troubleshooting, and access permission control
are general ly required. As such, management
achieves the M3 level (operable).
