The application belongs to the technical field of mobile communication, and specifically discloses a TDMA
access method based on mixed fixed and dynamic time slots of multi-service, which comprises the following steps: based on
time division multiple access (TDMA), a
time frame is divided into three segments, i.e., a synchronous
broadcast time slot segment, a fixed allocation time slot segment and a dynamic reservation time slot segment, and the three segments are cycled in a
time frame period to obtain a time slot structure of a mixed TDMA multiple access protocol; based on the time slot structure, time slot allocation is performed; frame structures corresponding to three types of service data, i.e., periodic data, burst data and real-time
voice data, are respectively constructed, service data frames are generated according to the frame structures corresponding to the service data, and the service data frames are configured in specified time slots in the fixed allocation time slot segment or the dynamic reservation time slot segment. Through the application, the requirements of small protocol control overhead, low
time synchronization precision requirement, no priori parameter and high time slot
utilization rate in a low-load network can be met in a multi-service complex environment.
