1、SEPTEMBER 28,2023 ERICSSON TECHNOLOGY REVIEW ERICSSON TECHNOLOGY REVIEW SEPTEMBER 28,2023BY:ERIK EKUDDEN,CTOBuilding the platform for next-level digitalization One of the most exciting aspects of my career at Ericsson is the opportunity to participate in shaping transformative innovations.Over the c

2、ourse of the last two decades,the tandem evolution of internet technology and mobile networks has played a pivotal role in the digitalization that has utterly transformed both business and society.A high degree of embedded openness has enabled the rapid creation of a wide variety of novel,highly inn

3、ovative services,and we see that new technologies are being adopted more quickly than ever before.For example,global 5G subscriptions topped the 1 billion milestone at the end of 2022,which is two years faster than the 1 billion milestone for 4G.The digitalization of industry and society has profoun

4、dly changed how most people and organizations consume products and services.As a next step,the mobile industry will transition toward a business platform model that enables the creation of a truly open platform for business and technology innovation.Cloud and artificial intelligence(AI)technologies,

5、programmable networks,application programming interface(API)exposure and as-a-service business models are all instrumental in this process.A network platform providing seamless and efficient connectivity and communication services will be essential to link consumers,enterprises and society at large.

6、The network platform will have the ability to handle a large variety of use cases,from best-effort mobile broadband services to guaranteed quality of service(QoS),building a global platform for anyone or anything to consume its services.At the same time,it will minimize the cost and resource usage f

7、or these differentiated services,as well helping society and industry to reach net-zero emissions and other sustainability goals.The network platform is a cornerstone of a future world that is distance-free:a place where the physical and digital worlds coexist seamlessly and where both humans and ma

8、chines can connect,collaborate and engage with each other regardless of their geographical locations.Universal,resilient and trustworthy connectivity is the keystone of this cyber-physical world.With all of this in mind,I have chosen to focus on three key trends in this years article:1.Technologies

9、that enable a cyber-physical world2.The need for an open platform for business innovation3.The high-performing network infrastructureKEY TERMSThe business innovation platform is open,global and without boundaries,connecting consumers,enterprises and society at large,to enable the creation of new and

10、 innovative services that generate exponential business growth.It will be realized by the network platform.The network platform will aggregate and abstract the network capabilities from the distributed network infrastructure into monetizable,globally available services for developers and enterprises

11、.These services are enhanced by the integration of other value-adding functions originating from the global ecosystem.The network platform embeds interoperability and routing across the actors in the ecosystem to secure service continuity for global scale and reach.The distributed network infrastruc

14、ned a lot of attention in industry and society in recent years.At the same time,technology giants around the world have made significant investments to speed up technology development in this area,which has led to progress in both extended reality(XR)devices and applications.The evolution of immersi

15、ve communication that ties user experience to the physical world has been a recurring theme in my CTO Technology Trends articles for several years now.This year,I want to focus on two specific capabilities that are vital for a cyber-physical world.The first,massive twinning,connects and aggregates t

16、he physical world of senses,actions and experiences,and uses that information to generate a programmable digital representation.The second,situational awareness,refers to the use of sensing technologies to monitor the surrounding environment,locate objects,and navigate for smooth and safe interactio

17、n in a cyber-physical environment.Massive twinning real-time digital replicationThe creation of a digitalized and programmable physical world without temporal or spatial constraints will require massive twinning that is,the creation of accurate,fully synchronized digital twins of everything that exi

18、sts in the physical world,including humans,physical objects,processes and networked systems.Each digital twin knows its history,can predict its future and has full control of its real-time status.In massive twinning,all digital twins are fully synchronized.Vast amounts of data from the physical worl

19、d are sent in real time to update the digital twins for use by applications.Actuators and interfaces in the real world carry out functions from the applications for action and experiences.Massive twinning offers support to minimize resource use and fault prediction.One example of such a use case is

20、a real-time programmable digital twin of an entire smart city that enables precise modeling,monitoring and managing of almost any public or private service,such as utilities,public transportation,public health and environmental monitoring.Another important use case for massive twinning is process op

21、timization in a smart factory to improve productivity,flexibility,quality and sustainability.Massive twinning will also be of great use to communication service providers(CSPs)themselves by making it possible for the CSP to generate a digital representation of the entire network that can be used to

22、simulate network rollout,optimize network operations and initiate predictive maintenance.Ubiquitous connectivity and integrated sensing are essential components of massive twinning solutions.Massive twinning can involve hundreds of sensors and actuators per square meter,which means that the network

23、needs to provide advanced service coverage wherever and whenever it is needed to a broad range of devices and applications.This includes the aggregation of data rates up to gigabits per second,which leads to stringent requirements on very low latency and high throughput.In the 6G time frame,the netw

24、ork will provide connectivity using new and significantly more energy-efficient signaling protocols,and many of the sensors and actuators used in digital twins will be zero-energy devices that do not require any batteries or manual charging.To ensure massive twinning deployments at scale,a fully aut

25、omated process to handle sensor and actuator devices in bulk will be required.High network reliability and availability,as well as stringent end-to-end data and privacy protection,will also be needed to meet the required levels of trustworthiness.To fully unlock the potential of zero-energy devices,

26、a holistic approach is needed.For the devices themselves,the energy-harvesting technologies as well as the packaging and low-power integrated circuit design will need to be advanced.In collaboration with Massachusetts Institute of Technology(MIT),Ericsson is exploring new materials and ultra-low ene

27、rgy designs to harvest the radio signal itself.3ERICSSON TECHNOLOGY REVIEW SEPTEMBER 28,2023 The evolution from todays radio network simulators to network digital twins that utilize 3D gaming and computer-generated imagery technologies enables new features such as high-resolution of city and indoor

28、environments,detailing surface materials that influence radio frequency propagation as well as the representation of dynamic scene features such as automotive traffic and user mobility.Recent technological advances have improved Ericssons capability in several aspects such as visualization,integrati

29、on,standardization of formats,collaboration and modeling accuracy.Together,these advances enable leaps in our ability to accurately simulate a radio network in a digital twin.NETWORK DIGITAL TWIN FOR OPTIMIZING 6G NETWORKS CTO TECHNOLOGY TRENDS 2023CTO TECHNOLOGY TRENDS 2023 ERICSSON TECHNOLOGY REVI

33、CTORSEricsson has teamed up with NXP Semiconductors to investigate potential new use cases for a network where communication and sensing functionalities are fully integrated into the same transmission/reception nodes.Together,we will also investigate implementation aspects of such future systems and

34、 evaluate the technical challenges and opportunities for JCAS use cases.INTEGRATING SENSING INTO NETWORK INFRASTRUCTURES123ERICSSON TECHNOLOGY REVIEW SEPTEMBER 28,2023SEPTEMBER 28,2023 ERICSSON TECHNOLOGY REVIEW Situational awareness sensing surroundings and locating objectsSituational awareness is

35、the ability to understand the environment and its elements in real time and derive meaningful insights in order to make informed decisions and take appropriate actions.This capability is instrumental to building a cyber-physical world and is based on massive twinning data.The digital world is create

36、d by processing the sensing and localization information provided by simultaneous location and mapping(SLAM)algorithms.The SLAM information is used for a variety of purposes including AR,3D mapping,3D reconstruction and real-time object tracking.Spatial sensing capabilities will be an integral part

37、of the future network and have been identified as an innovative feature of future 6G systems.The future network will support spatial sensing by reusing network communication signaling,utilizing the same principles as radar technologies to determine the presence,characteristics and trajectory of obje

38、cts.This solution is referred to as joint communication and sensing(JCAS)and will enable services for evolving use cases such as smart cities,transportation systems and public safety applications.The network will collect not only JCAS sensor data but also other data from non-JCAS sensors.The network

39、 platform has the capability to process the aggregated sensor data to be used for services such as SLAM,navigation and geofencing.The network platform will offer the processed sensor data through network APIs that are easily consumable for the developer ecosystem.The main advantage of the network pl

40、atform in terms of future sensing is that most of the network infrastructure is already in place,providing full-area coverage that facilitates a synchronized multi-static sensory mesh.Another useful feature of the network infrastructure is that the radio signals for sensing work in complete darkness

41、 and can even sense local weather conditions.58 CTO TECHNOLOGY TRENDS 2023CTO TECHNOLOGY TRENDS 2023 ERICSSON TECHNOLOGY REVIEW SEPTEMBER 28,2023SEPTEMBER 28,2023 ERICSSON TECHNOLOGY REVIEW 7throughput.These capabilities will be exposed as network APIs tailored for next-generation use cases such as

42、immersive communication and situational awareness.Such future use cases can be further enhanced through the integration of other value-adding functions provided by the global ecosystem.For the most efficient and scalable implementation,the network platform will aggregate and abstract exposed network

43、 APIs from the distributed network infrastructures.Further,the network platform will embed interoperability and routing across the actors in the ecosystem to secure global scale and reach.The first step in this process will be the transformation of the existing network infrastructure architecture in

44、cluding functions such as the radio-access network,the core network,operations support systems and business support systems by strengthening the network API enablement suite in areas such as resource management and service orchestration.The second step will ensure that the network API enablement sui

45、te is equipped with state-of-the-art exposure frameworks and service definition;in other words,a network abstraction layer.As network infrastructure capabilities such as positioning,sensing and embedded compute evolve through 5G Advanced and 6G,the network API enablement suite will build new service

46、 segments and policies for service differentiation.An open platform for business innovation links consumers,enterprises and society at large across sectors and without boundaries.All producers develop and offer their own products,services or content through the platform.The platform will create conn

47、ections and enable transactions between producers and consumers.Existing platform users,both producers and consumers,will receive a benefit from every new user that enters the platform.As more users join,the advantage for existing users continuously increases.In economics,this is referred to as the“

48、network effect.”An additional advantage for users is that the platform scales without any significant investments.Inherent to the open platform for business innovation is its capability to support different use case characteristics from the simplest to the most advanced.The services are segmented ba

49、sed on shared requirements and needs to optimize fast deployments and minimize cost.The platform offers flexibility for the differentiation of products,services and content.In the future,enterprises will consume network connectivity and features as a service that fit their specific needs,similar to

50、the way cloud service works today.Depending on the use case,the service will be handled by a public network or by self-contained and independent logical network slices created in the public network that can extend into purpose-built private networks.Either way,the result is a virtual network offerin

51、g that is both secure and dedicated,with a single enterprise management system for enhanced asset control and visibility,including assets connected through the macro network.The role of the network platform Todays network platforms provide communication-as-a-service APIs by,for example,offering SMS,

52、video calling and voice services for developers to integrate into their application offerings.In the not-so-distant future,it will be possible to provide developers with much more advanced and programmable network capabilities tailored to application requirements on latency,reliability and Together

53、with three CSPs and a few of our ecosystem partners,we took the opportunity at MWC 2023 to showcase how to make advanced open-network APIs easily available to the developer ecosystem.The demo exposed 5G network APIs to enable QoS-on-demand for interactive HD videoconferencing on mobile devices and l

57、enness Open access interfaces,open service interfaces via network APIs,open network infrastructure layers to cloud,transport and data pipeline interfaces as well as open network applications,such as rApps,are all crucial architectural principles of the network infrastructure.Service differentiation

58、and deployment flexibility will be enabled with the help of end-to-end managed network slicing that dynamically optimizes the network resources within the stipulated QoS during the network slice life cycle.Programmable networks will allow for the optimization of the overall network performance as we

59、ll as the customization of device behavior targeting specific use cases.Programmable networks build on cloud technologies for faster feature development,faster bug fixing and DevOps-like operations.This will enable CSPs to adopt a software-as-a-service business model for network applications such as

60、 billing,management systems and core network functions.Network-aware applications use knowledge of network capabilities to intelligently place application components where they will run with the greatest efficiency,performance and energy efficiency,taking into consideration factors such as where spe

61、cific hardware-acceleration capabilities are available.An architecture built on distributed network infrastructures also provides limitless connectivity that is,connectivity that provides the required data rate and latency,and is available wherever needed.Multi-connectivity,multipoint connectivity a

62、nd distributed MIMO(multiple-input,multiple-output)will be utilized to ensure robustness,performance and consistent quality,which will contribute to increased network reliability,availability and resilience(NRAR).Multipoint connectivity and distributed MIMO provide the ability to use many tightly co

63、ordinated network nodes to communicate to each specific device,which greatly enhances performance.To provide truly global coverage,the distributed network infrastructures will include non-terrestrial access components such as satellites and drone networks.As part of the longer-term radio-access evol

64、ution,spectrum utilization will extend into the sub-THz frequency bands.These very high frequencies create the possibility of highly accurate sensing for use cases such as JCAS.Energy-efficient networks will be built by optimizing energy performance end to end.At node level,hardware accelerators and

65、 related software components such as operating systems and drivers are essential for low-energy solutions.They will provide scalable traffic processing including features like multiple sleep states and fast activation.Further,smart network and AI-based features for site energy orchestration will be

66、embedded for network energy optimization.In the 6G time frame,the network infrastructure will be capable of providing more than 100 times higher capacity in comparison with todays network infrastructure,with peak rates over 100Gbps,wide-area consistency latency below 5ms and centimeter-level positio

67、n accuracy.The always-available,high-performance network infrastructure will offer truly global coverage in indoor,outdoor and non-terrestrial environments.This is made possible through interoperable service interfaces that interconnect all ecosystem actors on a global scale.Embedding trustworthines

68、sThe openness of the network infrastructure requires security assurance based on zero-trust principles never trust and always verify to secure all communication while constantly monitoring the trustworthiness of the communication.A secure,resilient and privacy-preserving network infrastructure is a

69、cornerstone in supporting all society-,mission-and business-critical use cases for humans and intelligent machines in a verifiable way.This requires seamless integration of AI-based automated security controls and assurance mechanisms to make it possible to respond in real time to both known and unk

70、nown threats.This will secure trustworthy network infrastructure that performs tasks reliably,maintains data provenance,confidentiality and privacy,as well as protecting against unauthorized access or manipulation.In a trustworthy system,secure identities are needed at all layers of the system infra

71、structure,connectivity,devices and the edge as well as in network-slicing functions.This can be enabled by means of root-of-trust mechanisms for identities.To ensure both security and privacy,the network infrastructure will use state-of-the-art protocol stacks including quantum-proof algorithms and

72、confidential computing capabilities to protect data when it is being processed and stored.Finally,the network infrastructure will support security assurance throughout the application communication path,including devices,all network domains and the application cloud.In the long term,this will includ

73、e support for bystander and spatial privacy-preserving solutions for immersive user experiences.Artificial intelligence in programmable networksNetwork infrastructure must have the flexibility to handle a large variety of use cases,which will be achieved through greater automation of network managem

74、ent.Programmability and distributed intelligence are the best ways to achieve this.Fully autonomous system operation is based on zero-touch deployment and operation across all stages of the life cycle,as well as on the ability to continuously optimize performance in real time.Network services will b
