Random access wireless communication system and random access wireless communication method

A random access radio communication system configured to perform downlink communication from a radio base station to radio terminals by random access, wherein

• the radio terminals include one or more radio terminals (referred to as “low latency terminals” below) requiring low latency and one or more radio terminals (referred to as “non-low latency terminals” below) not requiring low latency, and
• the low latency terminals and the non-low latency terminals are configured to be distinguished by service set identifiers (SSIDs),
• the system comprising:
• a terminal assignment destination control unit configured to distinguish the low latency terminals and the non-low latency terminals in accordance with the SSIDs and evenly distribute the low latency terminals and the non-low latency terminals into a plurality of communication channels;
• and
• a random access control unit configured to perform priority control on the low latency terminals and the non-low latency terminals for each of the plurality of communication channels so that the downlink communication in each of the low latency terminals satisfies a predetermined delay time.
