This application discloses a method, apparatus, device, storage medium, and product for identifying illegal outbound calling behavior, relating to the field of big data technology. The method includes: constructing a knowledge graph based on multi-dimensional entity data that conforms to the characteristics of illegal outbound calling behavior; the multi-dimensional entity data including at least call data, base station data, order data, product data, merchant data, and location data; determining the importance ranking value of user number nodes based on the weights of user number nodes and the weights of their corresponding edges in the knowledge graph; identifying high-risk number nodes based on the importance ranking value of user number nodes and a pre-trained illegal outbound calling number identification model; and identifying high-risk products and high-risk merchants based on the link relationships of high-risk number nodes in the knowledge graph. Through the above methods, multi-dimensional data is integrated to construct a complex knowledge graph, calculate the importance ranking value of user number nodes, and accurately identify potential illegal outbound calling numbers.

This system utilizes inter-cell multiplexing gain through spatial processing of wireless communication networks. [Solution] A multiple antenna system (MAS) with multi-user (MU) transmission ("MU-MAS") that increases the capacity of a wireless communication network by utilizing inter-cell multiplexing gain through spatial processing. Over the past 30 years, the wireless cellular market has experienced a global increase in subscriber numbers, as well as a demand for better services shifting from voice to web browsing and real-time HD video streaming. This increasing demand for services requiring higher data rates, lower latency, and improved reliability has driven the rapid evolution of wireless technology through different standards.

This invention discloses a satellite trunking terminal number book and subscriber information data recovery system. When a terminal registers for network access, the system verifies the user's identity based on the Mobile Station International Subscriber Number (MSISDN) corresponding to the currently registered SIM card's International Subscriber Identity (IMSI). It checks the registration and binding relationship between the mobile trunking device identifier (TEID) and the MSISDN, as well as the binding relationship with the system. If the system determines that the user has changed their mobile phone, it prompts the user to rebind. After the user initiates binding, the core network modifies the MSISDN and TEID to the new binding relationship. When the user selects trunking data synchronization recovery, the system migrates and downloads the trunking number book and subscriber information to the new mobile phone. The data transmission path from the terminal to the gateway station's air interface must ensure the integrity and reliability of the downloaded data, allowing the user to restore all trunking functions—including individual calls, group calls, SMS, status, data communication, trunking group, location, and status management—simply by clicking "synchronize" on the satellite.
