Segment type time slot distributing method and device

The embodiment of the invention provides a segment type time slot distributing method and device, wherein the segment type time slot distributing method is applied to a node in a wireless network, wherein the segment type time slot distributing method comprises the following steps: the node determines a starting boundary value, which is used for distributing a time slot, of the time slot in a current time slot distributing stage; the node calculates a time slot length required in the current time slot distributing stage; the node selects a time slot index required by the current time slot distributing stage from the starting boundary value. The time slot is distributed by using the method provided by the embodiment of the invention, the time slot distribution and business volume are combined in a network, and the time slot index of each node is relatively appropriate. Meanwhile, one packet corresponds to one time slot, and no case that the time is reserved but not used is caused. Further, compared with most of existing methods, the segment type time slot distributing method has the advantage that the number of time slots completely used in a process of collecting all packets by a convergent node is less.
