Radio access method, apparatus, and system for implementing mutual transmission and processing of collaborative data between sites
First Claim
1. A radio access method for implementing a cloud radio access network (RAN) architecture that includes digital processing units (DUs) deployed in sites of an evolved universal terrestrial radio access network (E-UTRAN) architecture, the method comprises:
- receiving, by a switching device, first and second data packets sent by first and second DUs, respectively, in respective first and second sites, wherein the DUs support the E-UTRAN architecture;
determining, by the switching device, to send the first data packet to the second DU in the second site for collaborative processing that involves mutual transmission and processing of collaborative data between the first and second DUs,wherein the determination is based on a routing policy at the switching device for implementing the cloud RAN architecture based on the DUs arranged to support the E-UTRAN architecture; and
sending, by the switching device, the first and second data packets to the second DU, so that the second DU performs collaborative processing on the first and second data packets,wherein the first and second data packets are of a same data type comprising layer 2 (L2) scheduling data, hard bit data, frequency-domain in-phase-quadrature (IQ) data and time-domain IQ data.
