Equipment of Third Generation Mobile 
Telecommunication  
The third -generation mobile communications (3G) service will be 
terminated in December 2018. Due to the requirement for CSFB, 3G network 
will still exist in the mobile broadband (4G) network as heterogeneous 
networks. In other words, the third generation mobile communication 
technolo gy can provide services by using the frequency of mobile broadband 
services.  In order to meet the development needs of domestic mobile broadband 
services , the NCC refer to relevant international technical standards, and the
