Abstract

Cloud communication center system and method for processing data in a cloud communication system. An apparatus for supporting a cloud communication system may include at least one remote unit and a centralized unit. The at least one remote unit may be configured to process one of radio signals received from a user equipment or radio signals to be transmitted to a user equipment according to at least one sub-layer of an open system interconnection reference model. The centralized unit may be configured to receive the processed signal from the remote unit and to process the received signal based on the remaining sub-layers of the open system interconnection reference model.

Claims

1. A cloud communication system, comprising:

at least one remote unit included in a base station;

i) installed at a corresponding service area for forming a cell, as one part of the base station and ii) each of the at least one remote unit configured to process a first radio signal received from a user equipment and a second radio signal to be transmitted to the user equipment using a radio signal interface, wherein the radio signal interface generates a first processed signal by processing the first radio signal according to a physical layer of an open system interconnection reference model and transmit the first processed signal, wherein;

the remote unit includes

a radio unit configured to control a transmission and reception of signals to and from the user equipment; and

a physical layer unit configured to i) receive a second processed signal as data signals according to the physical layer of the open system interconnection reference model, and transmit the second processed signals as the second radio signals to the user equipment and ii) receive the first radio signals from the user equipment, process the received the first radio signals according to the physical layer and transmit the first processed signals; and

a digital unit i) included in a central office installed at a location physically separated from the at least one remote unit, as a remaining part of the base station, and connected to a core network through a switching system and ii) configured to receive the first processed signal from the physical layer unit and to process the received first processed signal using a data signal interface that process the first processed signal according to a media access control layer, a radio link control layer, a packet data convergence protocol layer and a radio resource control layer of the open system interconnection reference model, the digital unit further configured to transmit the second processed signal to the physical layer unit,

wherein the digital unit and the at least one remote unit perform operations together as one base station.

2. The system of claim 1, wherein the central office is connected to a core network of a mobile communication system.

3. The system of claim 1, wherein the at least one remote unit is coupled to the digital unit through an inter-protocol interface.

4. The system of claim 3, wherein the inter-protocol interface comprises an L1/L2 interface that couples together a L1 layer and a L2 layer of the open system interconnection reference model.

5. The system of claim 3, wherein the inter-protocol interface comprises a transport channel of a radio interface protocol.

6. The system of claim 1, further comprising:

a control unit configured to control a signal transmission and a signal reception of the digital unit and the at least one remote unit.

7. The system of claim 6, wherein the control unit is contained within the second processing unit.
