Introduction

Analysis of the core framework of the standard

This technical standard constructs a four-layer business architecture: user layer-interaction layer-platform layer-network layer, and realizes protection against harassing calls through the linkage of the user call answering willingness database and the industry entity information database.

Functional modules	Technical points	Data interaction frequency
User willingness registration	Support 6 types of registration channels, 3 levels of willingness classification	Regular reporting at 01:00 every day
Industry subject library	10 major industry classification standards	Regular issuance at 20:00 every day
Network side protection	Combined with AI analysis and real-time blocking	Real-time interaction on demand

Key technology implementation path

Interface specification case

A provincial operator uses the SFTP protocol to achieve data docking. The file naming strictly follows the UserWishUpload_CMCC_20230801_001.csv format and uses UTF-8 encoding to ensure multi-language compatibility.

Implementation Suggestions

1. Phase-based deployment: Prioritize the establishment of the basic functions of the user willingness database, and complete the full business chain docking within 6 months
2. Data governance: It is recommended to use blockchain technology to ensure that the willingness data cannot be tampered with
3. User experience: Set up the "Willingness Radar" function to display the protection effect in real time
