ABSTRACT:
A packet communication system is constructed with a plurality of terminal side devices and a network side device including a dynamic identifier assigning portion141and a time slot allocation portion1242.The dynamic identifier assigning portion141transmits an identifier information assigned to the respective terminal side devices in an initial setting state to the respective terminal side devices by means of a control signal. When an identifier assignment release request is received from an identifier control portion100of the terminal side device in a usual state, the dynamic identifier assigning portion changes the state of an identifier assigned to the terminal side device to the non-assigned state. When an identifier assigning request is received, the dynamic identifier assigning portion searches identifiers in the non-assigned state and, when there is an identifier in the non-assigned state, changes the state of the identifier to the assigned state and notifies the terminal side device from which the identifier assigning request is transmitted of the identifier assigned to the terminal side device.
