As an important approach to the digital transformation of operators, capacity opening has always been one of the key research and investment directions in the industry. With the commercial deployment of 5G networks, 5G capacity opening is also on the agenda. What capabilities 5G can provide, what application scenarios it has, and how to deploy and develop capacity openness are all hot topics at present.
5G network capability and application scenarios
In 3 GPP R 15, gives the NEF (Network Exposure Function) of the relevant specification definition, open Function for 5G Network capacity, for AF (Application Function) to provide 8 standard open service ability, through the eight service can provide QoS capabilities, event monitoring, parameter configuration, equipment trigger, PFD billing management, traffic flow guidance, background and strategy, etc. On the one hand, the R16 specification complements and enhances the open services defined in R15, while adding NIDD (non-IP Data Delivery), Data analysis, and network status, MSISDN-less MO message, IPTV configuration and other open services. 5G open service capability will have a wide range of application scenarios in transportation, industry, agriculture and forestry, energy, industrial parks and other industries. Application scenarios of traffic strategy (QoS, traffic guidance, policy billing, etc.) service capability include OTT directional acceleration, QoS guarantee in campus, mobile office acceleration, MEC local traffic unloading, merchant sponsored traffic, etc. Application scenarios of equipment and event monitoring capabilities include asset inventory, logistics tracking, regional traffic management, emergency rescue, equipment failure handling, etc.
In addition to the 3 GPP NEF definition of service ability, along with the network section, edge computing, big data, the application of AI techniques in 5G network development, 5G network will abstracts more ability to provide to the business application layer, which includes network section, edge computing service, voice, and message, location services, 5G, data analysis service, etc.
Section refers to a specific network capabilities and features of logical network, through the ability to slice abstraction can open biopsy order, biopsy to create, sign, and monitoring ability such as API service, makes the third party to fulfill the sliced through the way of ability call quick definition, creating and end-user oriented slice dynamic contract and use.
5G combined with edge computing can provide strong support for more time-sensitive industry applications in the URLLC scenario, open basic resource service capabilities such as IaaS and PaaS for apps or cloud apps residing in MEC, and SaaS service capabilities such as flow optimization, encoding and decoding, firewall, NAT service, etc.
5G LMF can provide high-precision positioning capability based on wireless, terminal, user surface and other means, including single positioning, periodic positioning, event triggered positioning, etc. Its positioning service capability can better meet the positioning needs of low terminal power consumption and no need for APP residence in the field of Internet of things. It can be widely used in various scenarios such as road transportation, freight monitoring, environmental monitoring, and farming and animal husbandry tracking.
5G voice and message capabilities include message, voice, HD voice, multi-party call, multi-party video, etc., SMS/voice verification code, virtual number, etc., which has become a necessary network capability in enterprise communication, park service, transportation and other industries and has been widely used.
