Problems solved by technology

[0004] However, the fifth-generation (5th-Generation, 5G) communication system puts forward higher requirements for data QoS management, that is, it is necessary to implement more refined QoS management for data. In the prior art, the DRB-based Information transmission cannot meet the requirements of 5G communication system for QoS management

Embodiment Construction

[0092] The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings.

[0093] figure 1 A communication network applicable to the embodiments of the present application is shown. Such as figure 1 As shown, the communication system includes a core network 110, a primary base station 120, a secondary base station 130, and a user equipment (User Equipment, UE) 140. The core network 110 communicates with the primary base station 120 and the primary base station 120 through a protocol data unit (Protocol Data Unit, PDU) session, respectively. / or the secondary base station 130 communicates. A PDU session may include multiple flows (as shown by the arrows in the figure), and the QoS requirements of different flows may be the same or different. 130 provides the QoS requirement of the flow, and the primary base station 120 and / or the secondary base station 130 completes the mapping of the flow to the DRB. Co...

Abstract

The invention discloses an information transmission method and an information transmission device. The information transmission method comprises steps that a main base station is used to transmit a request message to an auxiliary base station, and the request message comprises identification information of a flow; or the request message comprises the identification information of the flow and a mapping relation between the flow and a data radio bearer DRB; the main base station is used to receive a response message used for responding to the request message from the auxiliary base station. According to the information transmission method and the information transmission device provided by the invention, the DRB mapped by the flow is determined according to the identification information ofthe flow by the main base station, the auxiliary base station, core network equipment, and user equipment, and then the QoS management of the information transmission is more refined, and therefore requirements of a 5G communication system in a dual connectivity scene on the information transmission are satisfied.

Description

technical field [0001] The present application relates to the communication field, and in particular to a method and device for information transmission. Background technique [0002] The Quality of Service (QoS) mechanism is a security mechanism of the network. Network devices process data with different priorities through the QoS mechanism, which is beneficial to avoid problems such as network delay and congestion. [0003] In the Long Term Evolution (LTE) system, the core network equipment maps different flows into Evolved Packet System (EPS) bearers, and an EPS bearer includes an S1 bearer and a Data Radio Bearer (Data Radio Bearer) , DRB), the core network equipment and the base station communicate through the S1 bearer, and the base station and the terminal equipment communicate through the DRB. In the dual connectivity (Dual Connectivity, DC) scenario, when the primary base station decides to transfer the DRB to the secondary base station , the primary base station n...
