24、,and high-quality wireless communication services.Femto cell,also called home base station,originated from 3G.It is mainly proposed toaddress the indoor coverage shortage caused by the higher frequency band of 3G systemscompared to 2G systems,as well as the challenge of diverting voice and data serv

25、ices from WiFitechnology.The Femto Cell can access operators network by utilizing DSL,cables,or fiber,thereby enhancing indoor signal and data transmission rates.Compared with traditional basestations,Femto Cell is inexpensive and has become an important solution for improving indoorsignals.4G wirel

26、ess data traffic has rapid growth,with 70%of business occurring in indoor scenarios.The rapid popularization of high-speed multimedia services has put forward higher requirementsfor network coverage and capacity.The traditional cellular network,which mainly relies on thecoverage of macro stations,is

27、 prone to blind spots or insufficient coverage in some discreteindoor scenarios.The construction and operation costs of using macro stations are relatively high,and the difficulty of building property coordination using indoor distribution systems is high,resulting in large construction and renovati

32、usAs a kind of cost-effective solution for indoor coverage enhancement,5G Femto solution hasreach the consensus of ICT industry.At first,the industry heat is now emerging.Secondly,industrial standard is gradually constructed and improved.Thirdly,chipset solutions are becomingmore and more diverse.5G

33、 Femto Products have matured and the industrial ecology is graduallyprospering.1.2.1.Standard Specification3GPP began to work on the Femto base station(HNB)standard in 2007.Later,3GPP 4G LTEnamed Femto base station as HeNB,and broadcast HeNB information to mark the type of HeNBstation in the radio i

34、nterface.It introduced the concept of CSG(Closed Subscriber Group)tosupport black and white name list based access and features of interoperability.At the same time,the optional HeNB GW function is introduced into wireless architecture to adapt to differentbackhauling network scenarios.In the 3GPP 5

35、G NR standard,RAN4 has included the Femto RFindex in the definition of Local area base station.CCSA in China has developed a series of standards for TD-LTE Femto cell in the 4G era.In5G Femto Technical Requirement White Paper92022,It has completed the technical research for 5G Femtocell,then launche

37、ndustry is in a high-speeddevelopment stage,and many manufacturers are committed to developing high-performancechipset supporting 5G technology to meet the needs of high-speed data transmission andlow-latency communication.At present,Qualcomm and NXP have mature chipsets for 5G Femto,and their chips

38、ets andsoftware have reached the commercial state.In addition,several chipset schemes of SmartLogic,Picocom and Ultichip in China have products or are under development.5G Femto chipsetsshow a trend of increasing integration,evolving to a one-piece solution that supports multi-mode,multi-band and co

40、f 5G technology andsemiconductor industry,more manufacturers may emerge in the future to launch new solutions.1.2.3.ProductsThe miniaturization and flexibility of the 5G Femto make it an ideal low-cost solution to fillthe coverage gap and provide high-speed data services.Operators and equipment manu

41、facturershave announced corresponding solutions and products to embrace this expected market.In 2022,China Mobile officially released the worlds first 2.6GHz 5G Femto,and furtherreleased 4G/5G dual-mode commercial Femto product in 2023,which can achieve DL 800Mbpsand UL 230Mbps throughput.NOKIA,SAMS

43、tion.5G Femto Technical Requirement White Paper102.Requirements Analysis2.1.Residential ScenariosAs previously discussed,there are dual challenges in current residential scenarios.On theone hand,certain residential settings experience issues of weak coverage and blind spots.On theother hand,with the

44、 gradual widespread adoption of applications such as ultra-high-definitionlivestreaming,video conferencing,online education,cloud gaming,and even virtual reality,thedemand for networks with high data rates,low latency,and extensive capacity has become anessential requirement.Considering the inconven

45、ience associated with deploying transmission lines withinresidential environments and the variable placement of devices,there is a notable demand forequipment deployment that is flexible,convenient,environmentally friendly,and energy-efficient.5G Femto have the capability to leverage existing reside

46、ntial broadband networks for Backhaul,and enable the Plug and Play feature,they significantly mitigate the challenges and costs ofdeployment.This allows for the rapid attainment of comprehensive indoor coverage,whileboasting attributes such as compact and aesthetically pleasing designs,low power con

47、sumption,and the capacity for effective management and control.As such,they stand as a preferred andoptimal solution.2.2.Retail ScenariosWith the widespread adoption of mobile smart terminals such as smartphones and tablets,along with the rapid proliferation of services like mobile payments,short-fo

48、rm video content,cloud gaming,and extended reality(XR),there is a pronounced demand for high-quality networksin various contexts.This demand extends to traditional retail spaces like shops,restaurants,andand business halls,as well as emerging venues like immersive gaming experiences and temporary5G

49、Femto Technical Requirement White Paper11e-Sports competitions.These establishments seek robust network connectivity to enhance theirbrand image and provide finely-tailored customer services,thus unlocking additional avenues forbusiness growth.The retail environment is characterized by its inherent

50、complexity and numerous internalpartitions.It is susceptible to signal attenuation due to architectural obstructions andgeographical barriers,leading to significant signal penetration losses and the emergence of signaldead zones within.In commercial zones with high foot traffic,wireless signal conge

51、stion canoccur,significantly compromising the user experience.Addressing these discrete areas of weakcoverage and blind spots using a distributed small cell approach often requires substantialinvestment.Moreover,installation work such as laying cables and drilling holes can disrupt theaesthetic appe

52、al of store interiors,causing inconveniences for business owners.5G Femto does not require new transmission lines.by utilizing the existing broadbandinfrastructure,its possible to achieve comprehensive coverage of retail spaces quickly and at alow cost,and deliver high-speed,stable,secure,and high-c

53、apacity networks,ultimatelyenhancing the user experience.5G Femto with mmWave is attractive to offload traffic byco-channel deployment in this scenario,because the inter-cell interference is mitigated naturallyby large penetration loss.2.3.Isolated Island ScenariosLimited spaces such as elevators an

54、d basements are enclosing environment,and outdoormacro and indoor base station signals cant penetrate in,so it is easy to become wireless signalcoverage of the island blind area.In such regions,there is a strong user perception foruninterrupted coverage,making them frequent sources of network compla

55、ints.These scenariostypically involve fewer users,short stay durations,and lower data demands,thus emphasizing theneed for cost-effective coverage solutions.Additionally,the closure of limited space is not5G Femto Technical Requirement White Paper12conducive to device heat dissipation,and there is a

56、lso a high demand for device miniaturizationand low power consumption.5G Femto can be rapidly deployed within enclosed island scenarios,offering a stable signalstrength without signal loss,thereby enhancing the user experience.Simultaneously,theirfeatures of low cost,compact size,and energy efficien

57、cy make them well-suited to effectivelymeet the demands of such scenarios.2.4.Special ScenariosWith the large-scale deployment and application of 5G,the demand for coverage in uniquesettings such as sea areas and mountainous regions is becoming increasingly urgent.Determininghow to accomplish 5G cov

58、erage in these specialized scenarios with minimal resources andinvestments has become a key area of focus.Typical application scenarios encompass a wide range,including low-traffic expansive areaslike oceans,mountainous regions,and plateaus;hazardous environments like oil,gas,petrochemical,and coal

59、mining sites;and emergency situations such as firefighting,rescueoperations,and disaster relief.Diverse scenarios present distinct requirements for networkequipment.5G Femto,due to their advantages of being cost-effective,energy-efficient,easy to deployand maintain,and capable of plug-and-play opera

60、tion through existing fixed broadband orsatellite backhaul,are well-positioned to promptly and effectively fulfill these varying demands.Wide-Area Low-Traffic ScenariosThe defining characteristic of wide-area low-traffic scenarios such as sea are,mountainousregions,and plateaus is the overall low tr

61、affic volume spread across these areas.These scenariosexhibit a heightened demand for seamless coverage communication,particularly critical in5G Femto Technical Requirement White Paper13emergency situations,yet sporadic instances of elevated traffic demands can also arise.Challenges encompass both t

62、ransmission and power supply in such environments,and there is asubstantial need for base station equipment with low power consumption and flexible backhaulmethods.Hazardous EnvironmentsThe intelligent construction within hazardous environments,such as oil and gas,petrochemical,and coal mining sites

63、,underscores a compelling demand for high-quality 5Gcommunication.These environments are characterized by adverse conditions,often featuringelevated temperatures,high humidity,and substantial dust levels.On-site situations are complex,characterized by high uncertainty and significant danger factors.

64、Furthermore,these scenariosencounter limitations in available space.As such,there is an urgent requirement for base stationequipment with a simplified network structure that allows for agile deployment andstraightforward maintenance.These stations must not only meet safety requirements forexplosion-

65、proofing but also minimize deployment complexities and maintenance workloads.Thisdual focus on safety and efficiency is essential in achieving secure and effective operations withinsuch high-risk environments.Emergency ScenariosWithin emergency scenarios like firefighting,rescue operations,and disas

66、ter relief,thedemandforcommunicationisnotlongerlimitedtothevoiceintercomforkeycommunication.With real-time image and data transmission becoming pivotal for frontlinecommand decisions,the role of intelligent emergency robots has transcended human limitations,allowing them to operate within perilous e

67、nvironments and perform various tasks.Such contextscall for base station equipment that is readily deployable without the need for installation,capable of quickly providing communication services and real-time image transmission.5G Femto Technical Requirement White Paper143.Technical Requirement3.1.

68、Network Requirement3.1.1.Network Architecture5G Femto network architecture diagram is as follows.The main network elements include5G Femto,security gateway,signaling gateway,and network management system.5G Femto canaccess the core network through the dedicated transmission networks for operator,whi

69、chbelongs to the trusted domain network.The security gateway is an optional network element inthis case.It can also access the core network through fixed broadband or other IP networks,which belongs to the untrusted domain network.In this case,the security gateway is amandatory element.The 5G Femto

70、and security gateway establish IPsec tunnels to encrypt datapackets and protect data security.FigFigure 3-1 5G Femto Network ArchitectureThe functions of the main devices in the 5G Femto network architecture are as follows:5G Femto:Implements complete base station functionality.Security gateway:Perf

71、orms mutual authentication with the 5G Femto on behalf of thecore network.Signaling gateway:Aggregates signaling between 5G Femto and the core network.Network management system:Performs location verification of 5G Femto,devicemanagement for 5G Femto,security gateways,and signaling gateways,and achie

73、dropped calls and poor user experience.Synchronization includes frequency synchronization andtime synchronization.The synchronization technologies for 5G Femto mainly include air interfacesynchronization,GNSS synchronization,and IEEE 1588v2 synchronization.Consideringthat5GFemtoismainlydeployedinind

74、oorenvironments,GNSSsynchronization has higher costs and installation difficulties,while implementing IEEE 1588v2synchronization requires upgrading and modifying the transmission network equipment.Therefore,air interface synchronization is the preferred solution.It involves listening to thesynchroni

75、zation and broadcast signals of surrounding base stations to obtain the frame offsetinformation between 5G Femto and macro base stations,ensuring synchronization betweenneighboring cell clusters.Table3-1 Comparison of synchronization technologiesTechnologyBackhaulRequirementsEnvironmentRequirementsE

77、High3.1.3.SONTraditional network configuration and optimization typically require a large amount ofmanual intervention and adjustment,consuming time and resources.Self-Organizing Network(SON),as an automated network management technology,can automatically perform systemparameter configuration and op

78、timization through self-configuration,self-optimization,andself-healing.This reduces manual intervention,improves network deployment and maintenanceefficiency,and has been widely applied in mobile communication network systems.Due to the large number of deployments and the private and flexible locat

79、ions of 5G Femto,5G Femto Technical Requirement White Paper16it is more necessary to rely on SON to avoid dependence on manual network configuration andoptimization.Through wireless network intelligence and automation management,5G Femto canachieve“plug and play”functionality,improving network effic

84、 list,and increasing handover success rate.3.1.4.IPSecFor non-trusted domain backhaul,such as connecting to fixed broadband networks,an IPSectunnel is established between the 5G Femto and the security gateway to encrypt the data packetsand ensure data security.Communication parties use IPSec at the

85、IP layer to encrypt data packets,perform integrity checks,and authenticate data sources,ensuring confidentiality and integrity ofIP data packets transmitted on the network.It also provides features to resist replay attacks,supports certificate and EAP-AKA authentication methods.Data source authentic
