Abstract: Embodiments of the disclosure provide a radio access method, apparatus, and system, which can implement mutual transmission and processing of collaborative data between sites on a basis of low-cost deployment and high availability, and improve network performance. In the method, a basic DU is deployed in a site, and the method may include: receiving, by a switching device, a first data packet sent by a first basic DU; determining to send the first data packet to a second basic DU for collaborative processing; and sending the first data packet to the second basic DU, so that the second basic DU performs collaborative processing on the first data packet and a second data packet, where the second data packet and the first data packet are of a same data type. Embodiments of the disclosure are applicable to the communications field.

Abstract: A apparatus and system for exchanging data of an edge area user on a C-RAN are provided. The apparatus includes: at least one collaborative station of at least one neighboring C-RAN is determined for the edge area user on the C-RAN; control data is exchanged with the neighboring C-RAN collaborative station; a data exchange path used for exchanging first data with the neighboring C-RAN collaborative station is established according to the control data; the neighboring C-RAN collaborative station exchanges second data with the edge area user according to the control data. Based on the foregoing innovative mechanism, the C-RAN master station performs coupled collaboration with the neighboring C-RAN collaborative station by establishing the data exchange path, so that the neighboring C-RAN collaborative station may also exchange data with the edge area user, thereby enabling the edge area user on the C-RAN to obtain a better gain and improving system performance.
