Control method and system for network bandwidth

Abstract

The invention relates to the mobile communication technology field, in particular to a network bandwidth control technology. The invention discloses a network bandwidth control method, a system, a device and a network device thereof which are used for reducing the resource contention of the network bandwidth and improving the resource utilization of the network bandwidth. The network bandwidth control method includes the following steps: predicting the usable bandwidth for the network device according to the current flow data and the historic flow data of the network device; respectively generating the bandwidth control information for each network device according to the pre-allocated control policy and the predicted usable bandwidth of each network device; and controlling the corresponding network device flow respectively according to the bandwidth control information of each network device. The network bandwidth control device comprises a usable bandwidth predicting module, a control information generating module and a control module. The invention also provides a network bandwidth control system and the network device.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a network bandwidth control technology. Background technique [0002] With the rapid development of mobile communication technology, various data services relying on network broadband have become the development trend in the field of mobile communication. Vigorously developing network broadband services and stimulating network broadband applications have become the primary task and long-term development strategy in the field of mobile communication technology. Compared with the traditional voice service, the data service has great advantages, especially the packet data service. The packet data service means that the user can exchange data and transfer files with other user equipment at any fixed location or in motion through the user equipment. Extract data, access databases, etc. Packet data services only need to use the idle bandwidth to transmit data, and the ch...

Problems solved by technology

[0003] The rapid development of various data services has increased the demand for network broadband and brought huge challenges to mobile communication networks. At the same time, some problems have also arisen: for example, the data transmission rate provided by the network is limited, making the network traffic of various data services Due to limitations, it cannot meet the increasing needs of users; the resource utilization rate of network bandwidth is not high, in order to ensure that the services with high real-time requirements can be carried out normally, in the prior art, each service is divided into different services on the IP layer According to the business type, the corresponding network bandwidth resources are pre-allocated for each business. This reserved method makes a large amount of idle network bandwidth in the network unable to be effectively used, resulting in a waste of network bandwidth resources; it cannot respond to various emergencies in real time. Business needs, when there is a sudden business, it will often lead to network congestion, etc.

[0004] In the prior art, a network bandwidth adaptive control method for a single service network is also proposed, through the detection and control of the network equipment involved in the service network, to ensure the normal development of various services, such as the streaming media playback system, through detection Control the network equipment involved in this business to achieve the fluency of playback, etc., but cannot realize the adaptive control of the network bandwidth of the entire mobile communication network
