A network bandwidth guarantee method, device, system and terminal

Abstract

The invention discloses a network bandwidth method, device, system and terminal, which are used to adjust the network bandwidth according to the actual network state and notify the terminal side, so as to improve the reliability of the network bandwidth guarantee method. The network bandwidth guarantee method implemented by the network side includes: obtaining QoS parameter information reported by the terminal, the QoS parameter information at least including the current wireless network environment parameter value of the terminal; according to the obtained QoS parameter information and recorded network bandwidth allocation information , determining the network bandwidth actually applied for by the terminal; applying for corresponding network bandwidth according to the determined network bandwidth actually applied for by the terminal, and notifying the terminal of the network bandwidth actually applied for.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a network bandwidth guarantee method, device, system and terminal. Background technique [0002] VoLTE, or Voice over LTE, is a voice solution that uses LTE (Long Time Evolution, long-term evolution) network as service access and IMS (IP Multimedia Subsystem, IP Multimedia Subsystem) network to realize service control. It supports high-definition voice, high-definition video, etc. The communication service can also realize voice compatibility and intercommunication with the existing network 2G / 3G. VoLTE can provide high-definition voice and low-latency video calls. At present, some parameters of VoLTE video calls can be set as shown in Table 1: [0003] Table 1 [0004] [0005] For different video resolutions and frame rates, the terminal applies for network bandwidth from the network side. The current VoLTE video call network bandwidth guarantee uses...

Problems solved by technology

However, the following problems may still exist in practical applications: the wireless network quality of the network where the terminal is currently located is poor, and there is enough network bandwidth allocated to the terminal on the network side. The actual network bandwidth available to terminals with poor quality is not all the network bandwidth allocated by the network, and the terminal still uses the code rate corresponding to the applied network bandwidth for encoding and decoding. Since the actual network bandwidth used by the terminal is lower than the applied network bandwidth, this will cause the terminal to encode On the other hand, during a VoLTE call, even when the video call starts, the actual network bandwidth used by the terminal is the same as the network bandwidth applied for, but with the VoLTE service in the cell Due to the increase of terminals and other reasons, the network status of the wireless network, transmission network and core network is constantly changing. During a VoLTE video call, the actual network bandwidth provided by the network side may be lower than the network bandwidth requested by the terminal. This will also lead to decoding errors on the terminal side, reducing the quality of VoLTE video calls

It can be seen that the reliability of the existing network bandwidth guarantee method is low, and how to improve the reliability of the network bandwidth guarantee method to ensure the quality of business processing such as VoLTE video calls has become one of the technical problems to be solved urgently in the prior art
