Synthesizing user perception and usage data for better network planning using a service evaluation map for self-intelligent 5G networks.
New network technologies are constantly iterating, putting forward higher requirements for autonomous operation and maintenance of communication networks, and the requirements for communication services in various sectors of society have far exceeded the scope of traditional services. By implementing the Smart 5G business philosophy of being smarter, more agile and greener，our Catalyst project will solve the needs of the transformation from traditional communication services to new information services, improve the supply capacity of information services, promote the coordinated development of the upstream and downstream of the 5G industry chain, and help realize the value goal of the digital intelligence transformation of the whole society. In promoting the project forward，there are three major challenges： Challenge 1, How to deeply integrate AI technology with 5G new technology, and embed AI and data intelligence into all aspects of 5G operation and network operation and maintenance is still the focus of current operators. Aiming at reducing enterprise operation and maintenance costs, improving operational efficiency, and upgrading network intelligence through self-configuration, self-optimization, and self- healing. Challenge 2, How to collect and sort out user perception data by intelligent means, predict business quality and user experience changes in advance, and finally achieve network supply capacity based on user experience needs, and consolidate customer understanding and heart-level service feelings is still a major topic. Challenge 3, How to achieve hierarchical management of network self-intelligence capabilities, provide differentiated network information services according to the needs of various industries in society, incubate more business scenarios, help various industries improve service capabilities, green management, and help realize the transformation of social digital intelligence is the biggest challenge we are currently facing.
