Embodiment Construction

[0047] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments . Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0048] like figure 1 As shown, the RAN architecture in the 5G network is divided into CU and DU. CU contains the functions of PDCP, and DU contains the functions of RLC, MAC and PHY. The interface between CU and DU is F1, and the main functions performed include: node connection establishment, modification and deletion, user context establishment, modification and deletion, etc. Further, CU can be divided into wireless control plane (CU-C...

Abstract

Disclosed in the present invention are a service quality data stream processing method and apparatus. The method comprises: a first network element determines a mapping relation between a service quality data stream and a data radio bearer; and the first network element sends the mapping relation between the service quality data stream and the data radio bearer to a second network element.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a method and device for processing quality of service data streams. Background technique [0002] With the continuous evolution of 4G and the development of 5G technology, the mobile communication RAN (Radio Access Network) is undergoing a structural change to improve deployment flexibility and enhance network dynamics, so that the future 5G network can meet the needs of various services. Increased performance requirements. Among them, the direction of RAN architecture change includes "sinking" some functions to the edge of the network, increasing the flexibility of RAN, etc. The emerging RAN architecture should be able to improve spectrum resource utilization, hardware device performance, and energy efficiency. [0003] In 5G, the architecture of RAN is divided into CU (Central Uni, centralized unit) and DU (Distributed Unit, distributed unit). It includes the function...
