1 Brief Summary

With the development of wireless communication and the maturing of IoT business

mode, mobile network connections will increase rapidly from 7 billion to 100 billion.

Mobile networks can generate more revenues if the network capability is exposed

to third party service providers, such as over the top (OTT) and vertical industries.

Network Capability Exposure focuses on the monetization of the pipe capability of

mobile networks. It improves the efficiency of network management by combining

services and mobile networks, helping carriers and OTT service providers in the

Internet/vertical industries realize the win-win business mode of combining contents

and pipe.

Based on the in-depth analysis of demand in scenarios of exposing MBB network

capability, the following three aspects are critical in exposing network capability for

the industry chain.

Mobile network pipe capability exposure will become a new growth point for •

carriers. Major carriers in the world are providing capability exposure services.

Major OTTs in the world including Youtube, Amazon and Netflix are requiring

carriers to optimize services based on network capability exposure.

The realization of capability exposure depends on specific network architecture •

and exposure capability. Network architecture should be flexible and compatible

with both current deployment requirements of mobile networks and the features

of future 5G network evolution. Capability exposure should support different

application scenarios.

Successful mobile network capability exposure depends on the coordination •

and cooperation of the industry chain. Carriers provide network capability.

OTTs and industry service providers combine the pipe and concrete services.

Telecommunications equipment vendors implement architecture and solutions.

Standards organizations and industry alliances promote the standardization

and globalization of services. Terminal vendors optimize services based on their

network capability.

2 Scenarios and Requirements

2.1 Scenarios

Internet of Vehicles

Auto manufacturers hope to construct an interaction system between the driver,

automobile, and infrastructure based on vehicle-mounted communication module.

Based on mobile communication technology of low latency, high reliability and

density, as well as vehicle-mounted terminal information such as location and traffic

congestion, connection monitoring technology will support Internet of Vehicles better.

Telemedicine

With the miniaturization of professional/non-professional medical equipment and

popularity of implanted medical equipment, integration of medical equipment and

mobile network is increasing, especially for remote diagnosis system and wearable

medical monitoring equipment. Telemedicine has high requirement for reliability, low

latency, and customized interconnecting capability.

Industry in the Future

In recent years, Europe and the United States have proposed the notion of Industry

4.0 and Industrial Internet. Future industry is likely to be one of the largest potential

markets for mobile telecommunications. Future industry includes a wide variety

of equipment and has a high level of automation and requirement for operating

environment. Its most critical communication requirements are reliability, low latency,

and command capability over numerous mobile terminals.

Mobile Medical Detection

Industry Network Emergency Communication

Vehicle Connection HD Video

HD Video

Unlike the voice interaction in 2G and text/image interaction in 3G, video interaction

in LTE is thriving. However, video calling/transmission, especially online service of

HD video has not popularized since video occupies high bandwidth and consumes

much data traffic. The improvement in user experience and preference depends on

the existing network status of the terminal. The fluency of the video service can be

ensured by providing QoS and video service optimization. The efficiency of video

transmission can be improved by eMBMS.

Critical Communication

In natural disasters such as earthquakes and tsunamis, the communication capability

obtains partially paralyzed under extreme conditions. Casualty and property loss can be

reduced by ensuring the communication capability of public functional departments

such as fire fighting and public security. In tornadoes, floods, and fires, the efficiency

of service providers in the preceding industries will be improved by providing

communication capability dispatching and assurance, accurate survivor positioning,

and rescue information broadcasting with mobile terminals that can recognize rescue

teams.

Mobile Payment Security

With the development of mobile Internet, methods for payment are constantly

changing. Mobile payment and Internet finance bring risk alongside huge

convenience. The popularity of mobile payment can be realized by partially exposing

context information in the network such as the subscription, location, and terminal

information about UEs to mobile payment service providers so that they can provide

payment security solutions.

4

Network Capability Customization

In existing networks, the majority of third party services are transparent to mobile

network pipes. The network side cannot be optimized based on the features of

services and terminal status. By implementing the information interaction between

network and service with capability exposure, carriers can implement QoS control

and sponsored data service on relevant service processes, so that intelligent traffic

management of pipes can be achieved.

With the maturing of service chaining/eMBMS and other new technologies, mobile

network carriers are able to provide differentiated services for special requirements.

The requirements include security, encryption, and other service chain optimization

for services such as online payment, government-enterprise communication, eMBMS

transmission, video acceleration and rate optimization, and other service chain

optimization for online video services.

Network Context Pattern

In future scenarios of mobile Internet application, the network context information

about UEs (location, ID, terminal capability, service type, access type, QoS, historical

location track, cell congestion) will become an important factor for the monetization

of network resources. Based on preceding context pattern about UEs, mobile

network carriers can optimize network resource more efficiently, or implement load

sharing, paging optimizing, and other functions. Third party also needs to optimize

corresponding services based on context information about UE.

2.2 Requirements

In the 2/3G era, service types are scarce and Internet capability is in surplus. With

the rapid increasing of mobile Internet application/traffic, future mobile internet will

become the foundation of Industrial Internet, IOT, and other vertical industries. Only

the convergence of intelligent pipes and services can ensure ideal service experience

and enable carriers to provide more services. This is the main goal for mobile network

capability exposure. To achieve the preceding goal, mobile network capability

exposure needs to meet the requirements after analysis into preceding scenarios:

network capability customization and network context pattern.

Network layer

Network layer is the network infrastructure, including RAN, EPC, Gi-LAN, eMBMS,

OSS, and other systems of traditional mobile network, as well as MANO in the next

generation network based on SDN/NFV and various VNF. The network layer is the

foundation of network capability exposure, mainly implementing information reporting

and policy implementing. Network layer reports various information concerning UE

and NE granularity. The network layer receives and implements the policy delivered

by capability layer, such as adjusting QoS, implementing eMBMS service, congestion

control, resource allocation, and other policies.

Capability layer

Capability layer (also known as Open Mobile Foundry) is a primary platform for

network capability exposure located between network layer and application layer. Its

functions consist of Mobile Network Service Fabric (MNSF), Service Capability Opening

Function (SCEF), Analytics, and Mobile Network Programming Function (MNPF). MNSF

and capability exposure bus converge information on the network side. Analytics

implements big data analysis for network information. MNPF abstracts network

information analyzed and orchestrates network capability. SCEF defines functional unit

for 3GPP, supports capability exposure services with process framework, and providing

application layer with specific API.

3 Architecture and Scheme for Network Capability Exposure

3.1 Architecture for Network Capability Exposure

The architecture for network capability exposure requires efficient and simple

interaction between the carrier network and third party application server, promoting

convergence of CT and IT. The Control, Context, Customization, and Content capability

of mobile network need to be abstracted, converged, and orchestrated by a unified

Open Mobile Foundry (OMF) node, the network capability exposure architecture based

on which includes network layer, capability layer, and application layer.

Application layer

Application layer is the API management body located on the top of the entire carrier

network, interacting with Open Mobile Foundry southbound, connected with third

party application platform/server on external network northbound. The application

layer on carrier network can directly invoke the internal API in the mobile network

provided by the capability layer and implement network optimization functions, such

as load sharing and network fragmenting. For the external API provided to third party

applications (such as vertical industry, government and enterprise services, third party

OTT, and other applications), the third party API management platform in application

layer is responsible for the authentication, charging, security of the API, and other

managements.

3.2 Capability for Mobile Network Exposure

Based on the preceding service scenarios and requirements, existing network needs

improving in network exposure capability in the following aspects:

QoS Exposure

Latency, bandwidth, and packet loss rate are the most intuitive and important

among all user experience. In a mobile network, end-to-end QoS is used to provide

differentiated services. OTT/industry service providers can apply for specific QoS to

mobile network on the network capability exposure platform. The network side will

assign bearer resources for service processes based on the service subscription and

network status.

Location Information Exposure

UE's location information is important for mobile networks, by the exposure of which

carriers can optimize their services and implement the monetization of network

information. In outdoor scenarios, based on positioning and historical location analysis

functions provided by mobile network, carriers can implement accurate advertisement

delivery, customer insight, and passenger traffic management at hot spots. In indoor

scenarios, by deploying indoor lampsites, mobile network carriers can overcome the

absence of GPS signal, implementing indoor positioning with precision of 5 meters.

Charging Capability Exposure

With the diversification of OTT services, traditional business mode where users pay to

the information has changed in many fields. Tencent Music, Xiami Music, and Youtube

all provides sponsored data services, where the traffic generated by subscribers is

paid by service providers to carriers. As services paid by third party increase, the

O&M cost can be slashed if unified management of sponsored data charging rules is

implemented on the network capability exposure platform.

7

Service Chain Capability Exposure

In the existing networks, carriers provide service process acceleration, encryption,

and other services through their service chains for video service and government/

enterprise service. Due to the inability to obtain accurate service information and

complexity in deployment, the benefits of service chain optimizing function based on

service identification are hard to exploit. This can be solved by providing third party

application servers with access to the service chain capability deployed in the network

and enabling the servers to optimize specific service chain with EPSN (Enhanced Packet

Service Node) based on the features of the service (service category, application tag,

video coding scheme, and other features) through the capability exposure platform of

network carriers.

eMBMS Capability Exposure

Traditional eMBMS services are only available to carriers' self-operated or government

affair clustering services. OTT cannot invoke clustering services of carriers. As video

service and network broadcasting rapidly develops, traditional unicast bearing

preceding services inflicts a huge burden upon terminal UEs and the network side.

Therefore, content providers should access to the network capability exposure

platform to invoke eMBMS capability. OTT and end users can initiate service request

with the network side, which will adopt eMBMS to bear corresponding service process

based on network status.

Mobile Edge Computing Exposure

With the exposure of network capability, content/services moves downward. Reasonable

deployment of computation capability at network boundary can significantly reduce

service latency and improve network efficiency. By deploying local applications at

network boundary, users are able to access local service resource through network

boundary. By providing third party application hosting service at mobile network

boundary, mobile network carriers can establish local application service platform for

small and medium-sized OTTs, and vertical industry service providers.

4 Industry Chain

Mobile network capability exposure mainly aims on digging into the relation between

network capability and service optimization. The exposure can also optimize user

experience, improve network efficiency, expand scope of service and increase service

profit by providing network capability for the optimizing of specific service. The main

beneficiaries of network capability exposure will be carriers, OTTs and various industry

service providers (such as vertical industry, finance, retailing, education, government,

enterprise, public security, transportation). The convergence of network and services

will generate new business modes, raising higher requirement for collaboration among

members in the industry chain.

4.1 Business Mode

In the traditional mobile communication business mode, carriers and end users are

main player. As mobile network application scenarios become increasingly diversified,

both service providers and charging modes will change. In scenarios such as IoT and

vertical industries, service providers will be heavily involved in the network with carriers

and end users. Service providers of video, music and game can pay for the traffic

generated by users accessing relevant services. M2M service providers can pay for the

communication cost generated by the corresponding M2M terminals. When service

providers or end users invoke specific network capability, carriers can charge based on

the capability invoked. Carriers will expand its B2C business mode to include B2B by

providing service providers with network capability and unified charging. Stable and

high-quality services in large quantity will bring considerable profit increase to carriers.

New business mode will change the industry chain. Carriers will evolve from network

service provider to network service/capability provider. By digging into and exposing

the network capability, carriers can strengthen their leadership in the new industry

chain. An industry chain of mobile network capability exposure is formed with the

participation of mobile network carriers, OTTs, industry service providers, equipment

providers/standards organizations, industry alliances and terminal equipment vendors.

Value innovation of the industry chain requires collaboration from every member.

Carriers provide network capability for third party to invoke. OTTs and industry service

providers propose specific requirements for mobile network capability and converges

network capability with features of service, improving service experience and network

efficiency. Network equipment vendors provide concrete architecture and scheme for

network capability exposure. Standards organizations formulate universal standardized

procedures. Industry alliances promote development by coordinating interests of all

parties involved. Terminal equipment vendors develop new terminal capabilities based

on network capability and features of service.

4.3 Industry Interaction

Standards organizations: join efforts with major carriers and equipment vendors across

the globe to formulate standardized end-to-end network capability exposure service

procedure covering end users, network, service platforms and application servers.

Different regions and regulations will generate different capability exposure scenarios.

It is the main responsibility of standards organizations to ensure the interconnectivity

between exposure services of different carriers and network elements of equipment

vendors. Major standards organizations including 3GPP, GSMA, OMA, IMT-2020 and

CCSA have collaboratively engaged in the standardization of mobile network capability

exposure.

Industry Alliance: parties in the industry chain rapidly promote the maturity and

evolution of the entire industry by collaboration and cooperation. Industry alliances

are an important entity for existing enterprises to promote innovative capability and to

implement joint development. Network capability exposure can become influential in

certain fields with the help of global or regional industry alliances, and bring member

enterprises new business, customers, markets and profit.

Industrial joint innovation lab: carriers, network equipment providers, OTTs and

industry service providers jointly establish core technology team, conducting relevant

researches. Based on the technological and resource advantages in their respective

fields, they can cooperate in developing, verifying, and business deployment

optimizing in multiple aspects such as technology innovation, product development,

solution and marketing, while accelerating innovation of service application on mobile

networks, so that an end-to-end multi-win innovative business mode is forged.
