Description

Technical Field

[0001] The present invention belongs to the fields of wireless communication and terminals, and more specifically, particularly relates to a management system for a prru power amplifier. At the same time, the present invention also relates to a method for activating a prru power amplifier. Background Art

[0002] A prru power amplifier is a device that upgrades the power of a traditional small radio frequency remote unit (prru) micro base station product and enhances the product's coverage ability. It can amplify the output power of the prru from (17 dBm to 23 dBm) to (40 dBm to 43 dBm), thereby transforming prru products into products that solve indoor and outdoor coverage problems in large and medium-sized scenarios, improving the breadth and depth of network coverage;

[0003] Problems existing in the existing prru power amplifiers:

[0004] (1) The output power of prru products is low, generally used for covering small-range scenarios. After being transformed and upgraded into prru power amplifiers, the coverage range is greatly expanded, and the parameters configured by the original prru need to be dynamically adjusted according to the application scenario, and this adjustment process is relatively professional and complex; the present invention can intelligently configure the parameters of the prru according to the application scenario, simplifying the activation process of the prru power amplifier;

[0005] (2) After the prru product is transformed and upgraded into a prru power amplifier, the prru is still monitored through the original base station network management system, and the newly added power amplification module cannot be directly incorporated into the monitoring of the original base station network management system. If a failure occurs in the newly added module and causes network coverage problems, the original base station network management system cannot identify it, and network coverage faults will not be able to be effectively excluded and solved in a timely manner;

[0006] In view of the above problems, we propose a management system and activation method for a prru power amplifier. Summary of the Invention

[0007] The purpose of the present invention is to solve the shortcomings existing in the prior art, and to propose a management system for a prru power amplifier.

[0008] To achieve the above purpose, the present invention provides the following technical solutions:

[0009] A management system for a prru power amplifier, comprising:

[0010] An Internet of Things module, which is built into the prru power amplifier and is used to upload the configuration and status information of the prru amplifier to the operator's Internet of Things gateway;

[0011] An interoperability server, which is established within the operator's internal network and is used for bridging and interoperability between the PRRU network management and the PRRU amplifier;

[0012] A monitoring server, which is established in the public network and is used to provide integrated status and alarm monitoring services of PRRUs and amplifiers to construction and maintenance personnel;

[0013] The monitoring server is connected to the interoperability server through the firewall via VPN, provides an RPC interface for the interoperability server to call, and the interoperability server regularly saves the common status and alarm status of PRRUs and PRRU amplifiers to the monitoring server, and then the monitoring server provides status and alarm monitoring services externally.

[0014] Preferably, the MQTT publish-subscribe protocol is adopted between the PRRU amplifier and the IoT gateway to provide an operation interface for the PRRU. The IoT module is only connected to the specified IoT gateway and cannot be connected to other network addresses except this IoT gateway.

[0015] Preferably, the interoperability server is connected to the IoT gateway through the MQTT protocol to implement the operation and management of the PRRU amplifier;

[0016] Moreover, the interoperability server is connected to the PRRU network management server through an IPSec tunnel, and through the rest interface provided by the PRRU network management server, the operation and management of the PRRU are realized.

[0017] A method for activating a PRRU power amplifier includes the following steps:

[0018] S1. Engineering personnel configure and write the PRRU serial number and application scenario information used by the PRRU amplifier into the PRRU amplifier; the PRRU amplifier uploads this information and the device's own information to the interoperability server;

[0019] S2. The interoperability server reads the parameters of the PRRU from the PRRU network management according to the PRRU serial number;

[0020] S3. The interoperability server calculates the cell coverage radius parameter according to the application scenario and configuration information of the PRRU amplifier and according to a preset configuration table, and then configures the cell coverage radius parameter to the PRRU network management;

[0021] S4. The interoperability server calculates the uplink noise floor alarm threshold according to the application scenario and configuration information of the PRRU amplifier and according to a preset configuration table, and then configures the uplink noise floor alarm threshold to the PRRU network management;

[0022] S5. The interoperability server reads the status of the PRRU from the PRRU network management, and after confirming that the PRRU is working properly, it turns on the output of the PRRU amplifier.

[0023] S6. After the output of the PRRU amplifier is turned on, the engineering personnel use a test terminal in the coverage area to search for the information of adjacent cells, and then configure and write the adjacent cell information into the PRRU amplifier.

[0024] Preferably, the parameters of the PRRU described in step 2 include:

[0025] PRRU connection status, RF working status, standing wave alarm status, cell coverage radius, uplink noise floor alarm threshold.

[0026] Preferably, the application scenario information described in step S1 includes:

[0027] Indoor distribution coverage, outdoor coverage, number of antennas, dual-channel coverage type.

[0028] Preferably, the device itself information described in step S1 includes:

[0029] Operating frequency band, maximum gain, maximum output power.

[0030] Preferably, in step S5, after turning on the output of the PRRU amplifier, the status of the PRRU and the amplifier is detected again to confirm that no standing wave alarm occurs in the PRRU and the amplifier.

[0031] Preferably, in step S6, the PRRU amplifier uploads the adjacent cell information to the interoperability server, and then updates the adjacent cell information to the PRRU.

[0032] Technical effects and advantages of the present invention:

[0033] 1. The present invention simplifies the commissioning and configuration project of the PRRU and the amplifier. After the engineering personnel complete the construction and installation, the management system can automatically complete the configuration update and status monitoring of the PRRU by inputting necessary information.

[0034] 2. The present invention centrally incorporates the alarm status information of the PRRU and the amplifier into the monitoring server through the interoperability server, realizes the unified monitoring of the PRRU and the amplifier, and can effectively eliminate network faults during the installation and maintenance process.

[0035] 3. The present invention physically isolates the PRRU configuration information and status information through the monitoring server, and only provides the PRRU and amplifier alarm information for public network access through the monitoring server, effectively protecting the information security of telecommunication network equipment.

[0043] A monitoring server, which is established in the public network and is used to provide integrated status and alarm monitoring services of the prru and the amplifier to construction and maintenance personnel;

[0044] The monitoring server is connected to the interoperability server through a VPN after passing through the firewall, provides an RPC interface for the interoperability server to call, and the interoperability server regularly saves the common status and alarm status of the prru and the prru amplifier to the monitoring server, and then the monitoring server provides status and alarm monitoring services externally;

[0045] It is worth noting that the MQTT publish-subscribe protocol is adopted between the prru amplifier and the Internet of Things gateway to provide an operation interface for the prru, and the Internet of Things module is only connected to the specified Internet of Things gateway and cannot be connected to other network addresses except this Internet of Things gateway.

[0046] In the above design, the PRRU configuration information and status information are physically isolated through the monitoring server, and only the PRRU and amplifier alarm information is provided for public network access through the monitoring server, effectively protecting the information security of telecommunication network devices.

[0048] Specifically for this embodiment,

[0049] This embodiment also provides a method for activating a PRRU power amplifier, including the following steps:

[0050] S1. Engineering personnel configure the PRRU serial number and application scenario information used by the PRRU amplifier into the PRRU amplifier; the PRRU amplifier uploads this information and the device's own information to the interoperability server;
