BANDWIDTH MANAGEMENT METHOD, EVOLUTION BASE STATION, SERVICE GATEWAY AND COMMUNICATION SYSTEM

摘要

In the field of communications technologies, a bandwidth management method, an evolved Node B (eNodeB), an S-GW, and a communication system are provided. The bandwidth management method is applicable to at least two first network devices and a second network device. The at least two first network devices share a transmission channel to perform data transmission with the second network device. The method includes: receiving, by the second network device, real-time traffic information sent by the first network devices; adjusting, by the second network device, transmission bandwidth of the at least two first network devices according to the traffic information and a preset adjustment rule; and sending, by the second network device, the adjusted transmission bandwidth information to the first network devices, so that the first network devices perform the data transmission based on the adjusted transmission bandwidth. Through the technical solutions, use efficiency of the transmission bandwidth between the first network devices and the second network device may be increased, and fairness of using the transmission bandwidth between the first network devices may be realized.
