Abstract

The invention provides a bandwidth scheduling method. In the method, a bandwidth allocation device receives a bandwidth request message sent by a message conversion device, wherein the bandwidth request message comprises a bandwidth requirement, and the bandwidth requirement is a bandwidth needed by a user side to complete service transmission. The bandwidth required. The bandwidth allocation device performs calculation according to the bandwidth requirement to obtain first bandwidth grant information and second bandwidth grant information, wherein the first bandwidth grant information is bandwidth information corresponding to the service and allocated to user side equipment, and the second bandwidth grant information is bandwidth information corresponding to the service and allocated to second access equipment. The bandwidth allocation device transmits the first bandwidth grant information to the user side equipment through the message conversion device. The bandwidth allocation device transmits the second bandwidth grant information to the second access equipment through first access equipment.

Description

technical field [0001] The present application relates to the communication field, and in particular to a bandwidth scheduling method and device. Background technique [0002] figure 1 It is a schematic diagram of an existing bandwidth scheduling method. Such as figure 1 As shown, in the existing bandwidth scheduling method, the user side device sends a first bandwidth request message to the second access device, and the first bandwidth request message includes the bandwidth requirement of the user side device. After receiving the first bandwidth request message, the second access device allocates bandwidth to the user-side device according to the bandwidth requirement of the user-side device. The second access device sends a first bandwidth response message to the user-side device, where the first bandwidth response message carries bandwidth information allocated to the user-side device. The user side device may send uplink data to the second access device according to ...
