APPARATUS AND METHOD FOR MANAGING SLOT

摘要

PURPOSE: An apparatus and a method for managing a slot are provided to manage a slot through the three times of command frame exchange and the primitive exchange of MLME(MAC sublayer management entity) and an upper layer. CONSTITUTION: A node 3 transmits a DSME-GTS(Deterministic And Synchronous Multi-Channel Extension Guaranteed Time Slot) request command for requesting the allocation of a slot to a node 1(S310). The DSME-GTS request command includes the number of a requested slot and information about a current DSME slot allocation bit-map sub block. DSME SAB(Slot Allocation Bitmap), sub block information has a bit-mapped form. The node 1 broadcasts assigned slot information and a DSME-GTS response command, which includes a destination address, to an adjacent node(S320). The assigned slot information includes the DSME SAB sub block information A node 3 broadcasts the slot information assigned to inform an allocation result to the adjacent node and the DSME-GTS notification command including the destination address to the adjacent node(S330).
