Embodiment 1

[0060] Miniaturized base station and RRU RUDP link building

[0061] A RUDP link needs to be established between the miniaturized base station and the RRU as a transmission channel for control plane data between the two. The miniaturized base station and the RRU cooperate to complete the RUDP link establishment software implementation process as follows: figure 2 As shown, the description is as follows:

[0062] Step 202, the miniaturized base station constructs an RRUID (RRU Identification) according to the RRU physical rack number configured in the background (OMC-B), and constructs an RRU optical port IP (Internet Protocol, Internet Protocol) and optical port according to the topology of the RRU MAC (Medium Access Control, Media Access Control) address;

[0063] Step 204, the miniaturized base station adds the optical port IP address of the RRU to its own host routing table;

[0064] Step 206, the miniaturized base station sends the RRUID to the RRU through FPGA (Field P...

[0070] Implementation of operation and maintenance functions

[0071] The combination of the miniaturized base station and the RRU needs to implement the operation and maintenance functions between the two. Here, the version management, parameter configuration functions, and alarm functions are described in detail.

[0072] version management

[0073] The version management function completes the RRU version update to ensure the consistency between the version used by the RRU and the background (OMC-B) version. The version management adopts the main control and agent design architecture. The main control process resides on the miniaturized base station, completes the function of downloading the version from the background, and completes the update of the RRU version by interacting with the agent process; the agent process resides on the RRU, and communicates with the main The control process cooperates to complete the RRU version update. Version management includes two parts...

Embodiment 3

[0123] This embodiment is used to describe the overall implementation process of the method of combining a miniaturized base station and an RRU. Figure 8 shown, the steps are described as follows:

[0124] Step 802, the miniaturized base station and the RRU complete the establishment of a UDP and RUDP link, as the bearer link of the control plane data between the two;

[0125] Step 804, the RRU completes the version update through the version management function to ensure the consistency between the version used by the RRU and the background version;

[0126] Step 806, the RRU obtains various parameters required for the normal operation of the RRU from the miniaturized base station through the parameter configuration module, including the center frequency, carrier, power level, IQ channel, VSWR and environmental monitoring threshold, dry node configuration and delay Wait;

[0127] Step 808 , the miniaturized base station and the RRU exchange IQ data according to the IQ exch...

Abstract

The invention discloses a cabinet-combining method and a device for a miniaturization base station and a radio frequency remote unit. The method comprises the following steps of: configuring a first port on the miniaturization base station, and a first light port is matched with an existing second light port of the radio frequency remote unit; establishing the miniaturization base station to be connected to the radio frequency remote unit through the first light port and the second light port, so that radio frequency resources of the radio frequency remote unit can be applied by the miniaturization base station. Due to the adoption of the invention, so that utilization ratios of base band resources can be improved, and carrier wave capacity of the base station can be improved.

Description

technical field [0001] The present invention relates to the field of communications, and in particular, to a cabinet merging method and device for a miniaturized base station and a remote radio unit. Background technique [0002] There are many types of mobile communication base station products. Traditional base station types can be divided into two types according to the degree of combination of baseband and radio frequency: distributed base station and integrated base station. The distributed base station separates the baseband and radio frequency to form BBU (Base Band Unit, baseband processing unit) and RRU (Remote Radio Unit, radio frequency remote unit). This design architecture can maximize the respective advantages of baseband and radio frequency. Get maximum integration, while RF focuses on maximizing its own power and efficiency. The integrated base station is different from the distributed base station. This type of station completes the hardware implementation ...
