Implementation and Application of One Mobile Phone Direct Connection Satellite Service Acquisition System Based on Wireless Link Monitoring
The development of mobile phone direct connection satellite technology will bring billions of users,which not only facilitates communication but also poses a serious challenge to information security.For this situation,a satellite service acquisition system for wireless link monitoring is designed to obtain satellite voice,short message and other services for commercial mobile phones.Similar to the DU-CU mode of ground mobile systems,the RF and baseband processing parts of the system are installed in a distributed form in outdoor signal towers,while the business processing part is centrally installed in the computer room to complete the business processing of multiple wireless receiving points.Tests have shown that the system can intercept satellite phone call services normally,and can store and replay them.
