METHOD FOR ALLOCATING CHANNEL TIME TO INTERNAL GROUP OF PICONET, PARTICULARLY FOR ENHANCING GENERAL PERFORMANCE OF THE PICONET BY REDUCING A CHANNEL TIME ALLOCATION BURDEN OF A PNC AND APPLYING OTHER TIME ALLOCATION METHOD THAN THE TDMA
METHOD FOR ALLOCATING CHANNEL TIME TO INTERNAL GROUP OF PICONET, PARTICULARLY FOR ENHANCING GENERAL PERFORMANCE OF THE PICONET BY REDUCING A CHANNEL TIME ALLOCATION BURDEN OF A PNC AND APPLYING OTHER TIME ALLOCATION METHOD THAN THE TDMA
A kind of purpose: method, one internal group of one piconet is arranged to enhance the performance of a piconet by reducing by a PNC (piconet coordinator) of weighing on for distributing a channel time, several channel times is received from more equipment and requests and handle it. Construction: the device of an entire piconet is grouped according to QoS characteristics (S710). One of group device is set as one group of head device (S720). Group head device estimates a time slot request of entire group members and the request time slot from a PNC (S730). PNC distributes message elements according to the existence or non-existence one suitable channel time of configuration of resource, broadcasts it to piconet by a floor lamp tower (S740). Group membership's device search channel time configuration block, PNC have broadcasted it by a floor lamp tower, successively (S750), it is determined whether the fields SrcID of each channel distribution block are equal with an ID of group head device (S760). If SrcID is equal with the ID of group head device, group membership's device is known that the channel time for being assigned to their piconet group. Each group membership's device is assigned time for communication allocated channel time (S770) and uses. Group membership's device sendes or receive data during the allocated channel time (S780) each other.
