Embodiment 1

[0060] Small base station and RRURUDP 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 RRUID (RRUIidentification) according to the RRU physical rack number configured by background (OMC-B), and constructs RRU optical port IP (Internet Protocol, Internet Protocol) and optical port MAC ( MediumAccessControl, medium 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 Programmable Gate Array, Field Programmable Gate Array);...

Embodiment 2

[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 illustrate the overall implementation process of the method of combining miniaturized base stations and RRU cabinets, as shown in Figure 8 As shown, the steps are explained as follows:

[0124] Step 802, the miniaturized base station and the RRU complete the UDP and RUDP link establishment, 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 that the version used by the RRU is consistent with 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 center frequency point, carrier, power level, IQ channel, standing wave ratio and environmental monitoring threshold, dry node configuration and delay Wait;

[0127] In step 808, the miniaturized base station and the RRU perform I...

Abstract

The invention discloses a cabinet merging method and device of a miniaturized base station and a remote radio unit. The method includes: configuring a first port on the miniaturized base station, the first optical port and the existing first port of the remote radio unit. The two optical ports are matched; the connection between the miniaturized base station and the remote radio unit is established through the first optical port and the second optical port, so that the miniaturized base station uses the remote radio unit radio frequency resources. By adopting the invention, the utilization rate of baseband resources can be improved, and the carrier capacity of the base station can be improved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a cabinet combining 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. The traditional base station types can be divided into two types according to the degree of combination of baseband and radio frequency: distributed base stations and integrated base stations. The distributed base station separates the baseband and radio frequency to form a BBU (BaseBandUnit, baseband processing unit) and RRU (RemoteRadioUnit, remote radio unit). This design architecture can maximize the respective advantages of the baseband and radio frequency, and the baseband can achieve maximum integration degree, while RF focuses on maximizing its own power and efficiency, each takes what it needs. The integrated base station is different from the distributed base station. This type ...
