A data sending method, device and computer program product

Abstract

An embodiment of the present invention provides a data transmission method, the method comprising: a first device acquires configuration information; receiving first data and indication information in a first stream transmitted by a second device through the first radio bearer; wherein, the The indication information is used to instruct the first device to select a radio bearer for the second data in the first flow according to the configuration information; The radio bearer of the second data is selected as the second radio bearer; and the second data is sent to the third device through the second radio bearer. It can be seen that the present application establishes a mapping relationship between radio bearers during data transmission through configuration information, and instructs the first device to select an appropriate radio bearer for data transmission through indication information to ensure data transmission. In addition, the embodiment of the present application also provides a corresponding data transmission device and related equipment.

Description

technical field [0001] The present application relates to the communication field, in particular to a data sending method, device and computer program product. Background technique [0002] At this stage, the communication technology of the Internet of Vehicles based on the cellular network is constantly developing, and the V2X communication technology has become a research hotspot of 5G; V2X communication refers to the communication method between the vehicle and other things, for example, the vehicle can communicate with the vehicle (Vehicle to Vehicle, V2V) or vehicle and roadside infrastructure communication (Vehicle to Infrastructure, V2I) or vehicle and pedestrian communication (Vehicle to Pedestrian, V2P) or vehicle and network communication (Vehicle to Network, V2N) to timely Obtaining road condition information or receiving information services, these communication methods can be collectively referred to as V2X communication (where X represents anything).

Problems solved by technology

However, in actual transmission, the data transmission requirements will change dynamically. If one device side adapts to change the corresponding relationship in order to meet the data transmission requirements, but the other device cannot perceive this dynamic change in time, it still follows the The preset corresponding relationship is used for data transmission, which leads to the inability to guarantee the data transmission performance; for example, the base station side and the device side are independently configured with the corresponding relationship between the flow identifier and the radio bearer; during the data transmission process, due to changes in business needs, The base station migrates the data in flow1 from the original radio bearer to another radio bearer for transmission to ensure the data transmission performance requirements of flow1, but when the device receives the data in flow1, it still uses the pre-configured flow ID and radio bearer Corresponding relationship, determine the wireless bearer to transmit the data in the flow1, the device cannot sense the change of the data transmission in the flow1 in time, and cannot guarantee the quality of data transmission
