Title: COMMUNICATION METHOD, DEVICE, AND SYSTEM
Abstract:
Disclosed in the embodiments of the present invention are a communication method, device, and system, belonging to the field of communication technologies. The communication method comprises: a first terminal determining, according to first mapping relation configuration information, the data priority corresponding to the identifier of a first radio bearer, the first radio bearer being configured by an access network device for the first terminal, the first mapping relation configuration information comprising the mapping relation between the identifier of the radio bearer of the first terminal and the data priority, the mapping relation being configured by the access network device for the first terminal; and the first terminal sending to a second terminal, according to the determined data priority, data to be transmitted corresponding to the first radio bearer. By configuring the first mapping relation configuration information for the first terminal by means of the access network device, the invention can determine the data priority of the data to be transmitted according to the identifier of the first radio bearer, and further can ensure the efficient transmission of the data of high-priority services.
