1, multiple users * * * enjoy one carrier frequency.
2. Discontinuous transmission makes handover easier.
3. Time slots can be allocated according to the requirements of dynamic TDMA.
4. Because the interference between cells is small, the power control is looser than CDMA.
Disadvantages are:
1, the synchronization overhead is higher than CDMA.
2. Complexity of frequency allocation
Time division multiple access allows multiple users to use the same frequency in different time slots. Users transmit quickly, one by one, and each user uses his own time slice. This allows multiple users to enjoy the same transmission medium (e.g. radio frequency).

Time division multiple access in mobile phone system
2G system mainly uses two systems:
One is GSM (Global System for Mobile Communications) proposed by the European Telecommunications Standardization Association (which later became the global cellular radio communication system standard). There are three main systems: GSM, DCS 1800, PCS 1900. More than 6,543.8 billion people in more than 200 countries and regions around the world are using GSM mobile phones. In People's Republic of China (PRC), China Mobile and China Unicom operate GSM networks respectively.
The other is called IS-95, and its core patent is owned by Qualcomm. In People's Republic of China (PRC), China Unicom operates its evolved CDMA2000 1X network (which has been handed over to China Telecom as its 3G network).
