METHOD, APPARATUS AND SYSTEM FOR BANDWIDTH DYNAMIC ALLOCATION

摘要

A method for bandwidth dynamic allocation, comprises: determining the channel bandwidth need for voice cluster signals; according to the channel bandwidth need for voice cluster signals, allocating channel bandwidth resources from the total channel bandwidth resources of a private network to a cluster communication device to transmit voice cluster signals; allocating the residual channel bandwidth resources of the private network to an Ethernet data transmission device; when the channel bandwidth currently allocated to the Ethernet data transmission device changes, notifying the Ethernet data transmission device to adjust the Ethernet data transmission rate according to the channel bandwidth currently allocated. The present invention also provides another method for bandwidth dynamic allocation, a transmitting device, a receiving device and a communication system correspondingly.
