Patent ID: 8385191

Claim:
A radio base station in which a radio control equipment is connected to a plurality of radio equipment via a Common Public Radio Interface (CPRI) link using a common public radio interface, comprising: a communication line directly connecting between the plurality of radio equipment, a vendor specific area on the CPRI link of another radio equipment and the communication line are defined as a bypass route of the CPRI link connecting a pertinent radio equipment to the radio control equipment, the radio control equipment comprises a plurality of line switch/data extraction and insertion units corresponding to the plurality of radio equipment for switching a line and inserting and extracting data in the vendor specific area; and a bypass communication route interconnecting the plurality of line switch/data extraction and insertion unit, the line switch/data extraction and insertion unit switches a line route from the CPRI link to the bypass communication route when there occurs a fault in the CPRI link to the corresponding radio equipment, inserts transmission data to the other radio equipment transmitted through the bypass communication route into the vendor specific area on the CPRI link for the corresponding radio equipment when the vendor specific area on the CPRI link to the corresponding radio equipment is used as a bypass route of another radio equipment other than the corresponding radio equipment, and transmits uplink data from the other radio equipment transmitted after inserted into the vendor specific area on the CPRI link for the corresponding radio equipment to the bypass communication route; and the line switch/data extraction and insertion unit corresponding to the other radio equipment fetches the uplink data from the other radio equipment through the bypass communication route.
