Data stream transmission control method and device

Abstract

The present invention provides a data flow transmission control method and device, including: obtaining the priority of user data flow and / or the service category of user data flow according to user information and / or congestion information; sending the user data flow, the user The data flow carries the priority and / or the service class, so that the RAN node of the radio access network differentiates and processes the user data flow according to the priority and / or the service class of the user data flow. The data stream transmission control method provided by the embodiment of the present invention obtains the priority of the user data stream and / or the service category of the user data stream according to the user information and / or congestion information, and then according to the priority and / or service class Data streams are differentiated and processed, which can effectively improve network performance and alleviate RAN congestion.

Description

technical field [0001] The present invention relates to communication technology, in particular to a data stream transmission control method and device. Background technique [0002] With the popularization of communication terminals such as smartphones and tablet computers, more and more users access mobile communication networks through terminals such as smartphones and tablet computers to use packet data services. [0003] When these terminals use packet data services, the data flow occurs on the user plane (UserPlane) of the mobile communication network. As a large number of mobile terminals install more and more applications that use network services, a large amount of data flow is generated, and due to the limitation of network capacity, data flow transmission congestion on the user plane is caused, especially at the air interface of the operator network , such as the long-term evolution wireless interface (Local Thermodynamic Equilibrium-Uu, referred to as LTE-Uu), t...

Problems solved by technology

As a large number of mobile terminals install more and more applications that use network services, a large amount of data flow is generated, and due to the limitation of network capacity, data flow transmission congestion on the user plane is caused, especially at the air interface of the operator network , such as the long-term evolution wireless interface (Local Thermodynamic Equilibrium-Uu, referred to as LTE-Uu), the wireless transmission channel between the terminal and the base station, the wireless node, the radio access network (Radio Access Network, referred to as RAN) and the core network (Core Network , referred to as CN) between the backhaul interface RAN user plane congestion, resulting in network performance degradation, affecting the user experience when using data services

[0004] In the prior art, there is no technical solution for effectively alleviating RAN user plane congestion
