Patent ID: 11895693
Assignee: NIPPON TELEGRAPH AND TELEPHONE CORPORATION
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. 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.
