<p>The present provides a RAN system, and which including: core network CN; a plurality of radio access gateway RAG each of which accomplishes the processing of all L1/L2/L3 protocol of the radio interface access layer; a plurality of remote radio unit RRU; wherein, a plurality of said RAG are connected with said CN via Iu interface, connecting between each RAG via Iur interface or via interface Iur+ interface, and said a plurality of RAG is connected respectively with the corresponding one of a plurality of said RRU via Iua interface for realizing a plurality of said RAG controlling, the corresponding one of a plurality of said RRU and digitalwireless signal transferring between RAGS and RRUs. In one specific embodiment of the present invention, each said RAG is separated two separated network unit of radio bearing server RBS and radio controlling server RCS. The above RAN structure proposed in the present invention overcomes the problem existing in the old UTRAN structure, solves the problem of frequent mobile management, and supports the structure that the RAN user's interface is separated from control interface with clear structure and. divided definitely function.</p> |
