COMMUNICATION SYSTEM AND BAND ALLOCATION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a communication system and a band allocation method that can use dynamic band allocation and improve the utilization efficiency of a transmission band when a passive optical communication network is used in a network between an aggregate station device and a base station device.SOLUTION: A communication system includes: an accommodation device that accommodates a user device by communication; a termination device connected with the accommodation device; and a terminal device connected with the termination device via a passive optical communication network. The accommodation device generates scheduling information on uplink communication from the user device to the accommodation device, and transmits the generated scheduling information to the user device and the termination device. The termination device transmits the scheduling information to the terminal device via the passive optical communication network. The terminal device determines the amount of band and start time of uplink communication from the termination device to the terminal device on the basis of the scheduling information, and transmits information representing the determined amount of band and start time to the termination device.SELECTED DRAWING: Figure 2
