Embodiment Construction

[0022] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] One of the core concepts of the embodiments of the present invention is to distinguish the types of services carried on the DRB. When it is determined that the service carried on the DRB is a video service, the bit rate is determined according to the definition of the video service. The bit rate is greater than The basic bit rate is the lower limit for guaranteeing the service carried by the DRB; furthermore, in the process of carrying the video service by the DRB, the bit rate corresponding to the video definition is used as the MinBR of the DRB, thereby increasing the The MinBR method of the DRB improves the transmission rate of the video data corresponding to the video service and ensures the smoothness of the video.

Abstract

Embodiments of the present invention provide a data processing method and device, wherein the method includes: judging whether the service carried is a video service; if the service carried is a video service, determining the corresponding Definition; determine the first bit rate according to the definition, the first bit rate is greater than the basic bit rate, and the basic bit rate is the lower limit of the rate for ensuring the service carried by the DRB; the video service is carried by the DRB During the process, the first bit rate is used as the minimum bit rate MinBR of the DRB. Therefore, the embodiment of the present invention improves the data transmission rate corresponding to the video service by increasing the MinBR in the process of DRB carrying the video service, thereby ensuring the smoothness of the video.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a data processing method and a data processing device. Background technique [0002] In the communication system, QCI (QoS Class Identifier, quality of service level) corresponding to each service is defined in 3GPP (3rd Generation Partnership Project, third generation partnership project), for example, the voice call service corresponds to QCI1, and HTTP (Hyper Text Transfer Protocol, hypertext transfer protocol) business to QCI9. Among them, QCI1-4 are GBR (Guaranteed Bit Rate, guaranteed bit rate) bearers, and QCI5-9 are Non-GBR bearers; for GBR's DRB (Data Radio Bearer, data radio bearer), respectively define the lower limit of rate guarantee and The upper limit of rate guarantee; for Non-GBR DRB, the upper limit of UE-level rate guarantee is defined, but because Non-GBR business is a best-effort business, the protocol does not define the rate guarantee of Non...
