Embodiments of the present invention provide a short range communications method, device, and system, and relate to the field of communications, so that a UE can distinguish, on a short range link, a radio bearer corresponding to transmission of data information. The method includes: establishing, by a benefited UE, a mapping between a short range bearer and a first radio bearer, where a mapping is performed between the short range bearer and a second radio bearer on a supporting UE side, and a mapping is performed between the first radio bearer and the second radio bearer on a base station side; and performing, by the benefited UE, data receiving and sending by using the mapping between the first radio bearer and the short range bearer.
