摘要

中国在2019年11月底正式实施已经试行了9年的携号转网政策。该政策会加强通信市场的流动性和竞争性，使运营商用户流失的问题更加突出。提出、验证并产品化了一种博弈论辅助的机器学习方案，以帮助运营商主动应对携号转网市场的竞争。所提方案为运营商提供了一种机器学习模型，检测用户的携转倾向，并给予差异化待遇。实验结果证明，所提方案能够指引运营商制定有针对性的携号转网策略，准确识别出有携入或者携出倾向的“异常”用户。此外，所提方案已被成功地产品化，极大地提高了运营商的营销效率，增加了用户的满意度，为中国某主要运营商减少了大约50%的用户流失。

Abstract

At the end of November 2019

China officially implemented the number portability policy (MNP) that has been in trial for 9 years.The policy will strengthen the liquidity and competitiveness of the telecommunication market

making the problem of subscriber churn more prominent.A game theory-assisted machine learning methodology was proposed

verified and commercialized timely

which could help mobile network operator (MNO) actively respond to competition in the MNP market.The proposed methodology provides MNO with a machine learning model to detect subscriber portability and give differentiated treatment.Experimental results show that the proposed methodology can guide MNOs to make a targeted MNP strategy

and precisely identify “abnormal” subscribers who tend to churn-out and potential new subscribers who may churn-in.In addition

the proposed methodology has been successfully commercialized

greatly improving the marketing efficiency of operators

increasing user satisfaction

and reducing the loss of users by about 50% for a tier-1 MNO in China.
