Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It is to be understood that the embodiments described are only some of the embodiments of the present application and not all of them. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1, a method for managing a small base station provided in the embodiment of the present application includes the following steps:
the wireless device is configured with at least one small cell site S100.
And a Small base station 13, namely Small Cells. They may be micro base stations, pico base stations, femto base stations. Typically covering a range of 10 meters to several hundred meters. Specifically, the small base station 13 has a small size and low power consumption. The whole system comprises a BBU, an RRU and an optional routing device. Flexible backhaul capability. The cellular mobile communication technology which can work in the authorized spectrum and the unlicensed spectrum is adopted, and the non-cellular technology such as WiFi is not included unless the LTE is integrated for access. The small base stations 13 are deployed to address network capacity issues in small areas, such as hot spots and important locations.
Further, in a preferred embodiment provided by the present application, in the case of a rapid development of communication technology, the application of the 4G small base station 13 deployed in a large amount before or the 5G small base station 13 deployed in a small amount now is very wide. The small base stations 13 known to us basically use the conventional tr069 protocol or the snmp protocol. the tr069 protocol or the snmp protocol manages the configuration, alarm, and performance of the small cell 13. In consideration of the characteristics of the 5G frequency band and the practical use situation of the indoor location, deployment in a dense networking manner is basically required. Because the management of the small base station 13 cannot achieve the ideal state of real accurate, no dead angle, and dynamic control anytime and anywhere, one wireless device is selected to be configured in the small base station 13, so that the small base station 13 can realize multi-directional management of the small base station 13 under the action of the wireless device.
Wireless device, namely Ble module 12 (bluetooth low energy module). The Ble module 12 is a very common wireless communication module, and supports the bluetooth protocol 4.0 or higher. The method has the greatest characteristic of reducing cost and power consumption, and is applied to products with high real-time requirements but low data rates. Compared with the traditional Bluetooth technology, a new function added by the low-power Bluetooth technology is a broadcast function. By this function, the slave device can inform it that it needs to send data to the master device. Bluetooth low energy technology employs variable connection time intervals, which may vary from milliseconds to seconds depending on the particular application. In addition, because the BLe technology employs a very fast connection, it can be in a "disconnected" state (saving power), where both ends of the link only know each other, open the link only when necessary, and then close the link in as short a time as possible. The main application comprises: location tags, asset tracking, motion and fitness sensors, medical sensors, smart watches, remote controls, toys, and the like.
It can be understood that, by the configuration of the Ble module 12, the small base station 13 can add a plurality of communication management modes on the basis of the original management, and perform multi-directional and multi-functional management on the small base station 13. The multifunctional management can be specifically interpreted as that after the Ble module 12 is configured in the small base station 13, other fault management functions for the small base station 13 can be added on the basis of the management of the remote network management system.
Referring to fig. 2, a block diagram of a communication connection of the management small base station 13 is provided according to an embodiment of the present application.
And S110, connecting the small base station configured by the wireless equipment with a remote network management system or a wireless equipment control end.
The control end of the wireless device controls the Ble module 12, and the control end of the wireless device may be a mobile phone with a bluetooth module, a computer, or other devices capable of transmitting a wireless network protocol. In the embodiment of the present application, the wireless device control terminal is a BLE control switch 14.
Further, in a preferred embodiment provided in the present application, a small base station 13 configured according to the Ble module 12 is connected to the remote network management system 10 or the Ble control switch 14. The method specifically comprises the following steps: the small base station 13 and the remote network management system 10 establish a first type of connection through a wireless transmission protocol. The Ble module 12 establishes a second type of connection with the Ble control switch 14 or the remote network management system 10 through a wireless transmission protocol.
It can be understood that, after the Ble module 12 is configured in the small cell 13, the original connection mode of the small cell 13 remains unchanged, that is, the first type of connection is established between the small cell 13 and the remote network management system 10 through a wireless transmission protocol. The second type of connection is that after the Ble module 12 is configured in the small cell 13, the Ble module 12 is connected to the remote network management system 10 or the Ble control switch 14, so as to add another function of managing faults of the small cell 13.
Further, in a preferred embodiment provided in the present application, the small cell 13 establishes a first type of connection with the remote network management system 10 through a wireless transmission protocol. The first type of connection is to implement a connection to the remote network management system 10 via tr069 network transport protocol. Through the first type of connection, management of the small base station 13 is achieved.
It should be noted that the TR069 protocol mainly accomplishes the following four aspects: user equipment auto-configuration and dynamic service configuration. And managing software and firmware of the user equipment. The status and performance of the user equipment is monitored. Diagnosis of communication failure.
It is important to note that the remote network management system 10 here can be a computer, a mobile phone or other software with the function of the wireless transmission protocol device. And a computer, a mobile phone or other equipment software with a wireless transmission protocol is used for carrying out fault management on the small base station 13.
Further, in a preferred embodiment provided in the present application, after the Ble module 12 is configured in the small cell 13, the Ble module 12 establishes a second type of connection with the remote network management system 10 or the Ble control switch 14. Through the second type of connection, the function of managing the fault by the small base station 13 is added.
Specifically, on the basis that the remote network management system 10 manages the small base station 13, the small base station 13 is configured with the Ble module 12, so that the small base station 13 is also controlled by the Ble module 12 at the same time. That is, the management method of the small base station 13 is changed to various methods. Through establishment in various ways, management ways of the small base station 13 are diversified.
Further, in a preferred embodiment provided herein, the Ble module 12 establishes a second type of connection with the remote network management system 10 or the Ble control switch 14. The method specifically comprises the following steps: the Ble module 12 and the Ble control switch 14 establish one of the second type of connection through a wireless transmission protocol. The Ble module 12 and the remote network management system 10 establish the second type of connection in the second type of connection through a wireless transmission protocol.
It should be noted that the connection of the Ble module 12 with the remote network management system 10 or the Ble control switch 14 of the second type needs to pass through the Ble mesh gateway 11. Mesh networks, i.e., wireless Mesh networks, are multi-hop (multi-hop) networks and are one of the key technologies for solving the problem of "last mile". In the process of evolving to the next generation networks, wireless is an indispensable technology. The wireless mesh can be cooperatively communicated with other networks, and is a dynamic and continuously expandable network architecture, and any two devices can be wirelessly interconnected. The Ble module 12 is a wireless communication protocol stack used by bluetooth mesh. Bluetooth mesh is not a wireless communication technology but a network technology. Bluetooth mesh networks rely on bluetooth low energy BLe. In the bluetooth Mesh network, low power consumption nodes can achieve the purpose of low power consumption by reducing the duty cycle of turning on a radio frequency transceiver (RF transceiver), and the low power consumption nodes can turn on the radio frequency transceiver only when needing to transmit and receive messages and are in a dormant state at other times. There is also a class of nodes in bluetooth Mesh networks that are dedicated to serving low power consuming nodes, which have a Friend property, and may also be referred to as Friend nodes. The Friend node and the low-power-consumption node can establish a Friend relationship. After the relation is established, the Friend node can temporarily store the information sent to the low-power-consumption node, and after the low-power-consumption node exits the sleep mode, the related information is retrieved from the Friend node.
There are various routing methods of the Ble mesh. The CSR Mesh networking technology based on Bluetooth 4.0 adopts the simplest and most reliable flooding routing algorithm. The flooding routing algorithm is also called a diffusion method, and the basic idea is that each node forwards a received data packet by using broadcasting, the distance between the nodes is 50m, and the data packet finally reaches a destination node through continuous one-level broadcasting of the nodes. The basic idea of the opportunistic routing algorithm is that each time a data packet is forwarded to a group of nodes, an optimal node is selected from the group of nodes, the optimal node is forwarded to the next group of nodes, and the data packet is received by repeating the steps until a target node, so that the success rate of data packet transmission can be greatly improved.
Further, in a preferred embodiment provided herein, the Ble module 12 and the Ble control switch 14 establish the first of the second type of connection through a Ble mesh protocol.
Specifically, the BLE control switch 14 controls the BLE module 12 through the BLE mesh protocol. After the Ble control switch 14 command is received by the Ble module 12, the corresponding Ble module 12 will issue a command to the small base station 13. After the small base station 13 receives the instruction sent by the Ble module 12, the small base station 13 changes its own operation state according to the instruction. The BLE control switch 14 may be a software on a laptop, a cell phone, or a device with wireless transmission protocol functionality. Software on a notebook computer, a mobile phone, or a device with a wireless transmission protocol function controls the plurality of small base stations 13. In the specific embodiment of this application, when single-point device trouble or field management personnel need control single equipment, field management personnel accessible cell-phone or have the bluetooth APP on the wireless transmission agreement function equipment to carry out accurate control.
Further, in a preferred embodiment provided in the present application, the Ble module 12 and the remote network management system 10 establish the second type of connection in the second type of connection through a wireless transmission protocol. The Ble module 12 is a Ble module configured in the small cell 13, and the remote network management system 10 is an original remote network management system 10 passing through the conventional tr069 protocol small cell 13.
It should be noted that the remote network management system 10 and the Ble module 12 cannot be directly connected through a protocol, the Ble module 12 is based on a bluetooth module, and the remote network management system 10 implements remote control through a network transmission protocol. Therefore, a protocol converter should be provided between the Ble module 12 and the remote network management system 10.
Specifically, the connection mode between the small base station 13 and the remote network management system 10 is as follows: a protocol converter is provided between the remote network management system 10 and the small base station 13. The Ble module 12 is connected to the protocol converter via the Ble mesh protocol. The protocol converter is connected to the remote network management system 10 via the tcp transport protocol. By the connection of the three, the mode of the remote network management system 10 for managing the small base station 13 is added, namely, the function of the remote network management system 10 for managing the small base station 13 is added.
Protocol converters, abbreviated as protocol converters, are also called interface converters. It can make the hosts adopting different high-level protocols on the communication network still cooperate with each other to complete various distributed applications. The protocol converter operates at the transport layer or higher. The interface protocol converter is typically implemented using an ASIC chip. The protocol converter has low cost and small volume. It can convert the Ethernet or V.35 data interface of IEEE802.3 protocol and the 2M interface of standard G.703 protocol. Or the conversion CAN be carried out on 232/485/422 serial ports, E1 interfaces, CAN interfaces and 2M interfaces. Protocol conversion is a mapping that maps a sequence of information (or events) transmitted and received from one protocol to a sequence of information transmitted and received from another protocol. The information that needs to be mapped is important information, so the protocol conversion can be regarded as mapping between the important information of the two protocols. The important information and the non-important information are relative, and are determined according to specific needs, different important information is selected for mapping, and different converters can be obtained.
It is important to note that in the second communication mode of the second type of connection, the protocol converter is a Ble mesh gateway 11. And the manager of the remote network management system 10 realizes the starting of the corresponding 5G small base station 13 by remotely controlling the Ble mesh gateway 11.
It can be understood that the remote network management system 10, the Ble mesh gateway, the Ble module 12, the Ble control switch 14, and the small base station 13 form a first connection type and a second connection type therebetween. In the operating state of the first type connection and the second type connection, the mesh network may also be interconnected to each other at the Ble modules 12 configured in the small cell 13 to serve as a relay. Mesh networks, i.e., wireless Mesh networks, are multi-hop (multi-hop) networks and are one of the key technologies for solving the problem of "last mile". In the process of evolving to the next generation networks, wireless is an indispensable technology. The wireless mesh can be cooperatively communicated with other networks, and is a dynamic and continuously expandable network architecture. Any two devices can keep wireless interconnection under the mesh network.
And S120, performing remote fault management on the small base station 13 through connection.
Further, in a preferred embodiment provided in the present application, the Ble control switch 14, the small base station 13, and the remote network management system 10 form a first type of connection and a second type of connection. The first connection mode and the second connection mode perform fault management of multiple modes on the small cell 13.
Further, in a preferred embodiment provided in the present application, the small cell 13 establishes a first type of connection with the remote network management system 10. Through the first type of connection, remote fault management of the small cell 13 is achieved. Specifically, the first-type connection established between the small cell 13 and the remote network management system 10 is mainly used for managing at least one of a configuration fault management interface, an alarm fault management interface, and a performance fault management interface of the small cell 13, for the small cell 13.
It should be noted that the first type of connection manages the fault interface of the small base station 13 through the remote network management system 10. When a specific fault is faced, the remote network management system 10 is required to remotely control the small base station 13 or repair the small base station in the field to solve the problem. The specific faults which can be solved by the remote control include various fault problems such as TRX frequency band and frequency point mismatching alarm, standing-wave ratio alarm, wireless link prompt alarm and the like. The remote network management system 10 handles the above-mentioned failure occurring in the small cell 13. For example, the radio link prompts for alerts are:
and (3) warning of channel activation abnormity: the main reason for this failure is that the bsc is inconsistent with the channel in the base station, so that the signaling and feedback problems of the log and the carrier frequency maintenance station can be obtained.
And (3) prompting and alarming for abnormal release of the channel: and performing radio frequency loopback test to observe whether the uplink code exists or not. And checking the session. The data configuration is checked. Look at sdcch performance measurement session. And using uplink frequency point scanning. The carrier frequency position is changed. It is checked whether the tightly covered cell is accessed by mistake. And acquiring field information.
Main bcch does not have the telephone traffic to point out and report to the police: the operation steps are the same as the channel abnormal release prompt alarm, and the difference is the bcch carrier frequency problem.
And (3) uplink and downlink balance prompt and alarm: the uplink and downlink levels are not balanced, requiring inspection of the uplink and downlink channels.
Further, in a preferred embodiment provided in the present application, the small cell 13 establishes a second type connection with the remote network management system 10. And remote fault management of the small base station 13 is realized through the second type of connection. Specifically, the small base station 13 is connected with the second type established by the remote network management system 10 or the BLE control switch 14. The method is mainly used for managing an abnormal hang-up management interface at least comprising the small base station 13. .
It should be noted that the second type of connection between the small cell 13 and the remote network management system 10 or the BLE control switch 14 is established because the small cell 13 cannot solve the fault through the first type of connection in the case of abnormal hang-up. The remote network management system 10 can remotely manage the small base station 13 through the second type of connection to solve the problem that the small base station 13 is abnormally hung up, and field maintenance by field managers is not needed. Meanwhile, the app on the device with the BLE control switch 14 can be used to control the failed device by the failed field manager. Through the two modes, the problem that the small base station 13 is abnormally hung is solved, and field management personnel are not needed to carry out field maintenance in the prior art.
Further, in a preferred embodiment provided by the present application, remote fault management is performed on the small cell 13 through connection, and specific location information of the failed small cell 13 can be further specifically determined.
It can be understood that, through the Ble mesh gateway 11, the remote network management system 10 can accurately obtain the specific location of the small cell 13.
It should be noted that, through the connection, the operation state of the small cell 13 can also be controlled in real time according to the service demand state of the small cell 13. In the embodiment provided by the application, the method is necessary for many office buildings at present. Most of the staff in the office building in the daytime have a great demand for the service provided by the small base station 13, and the flow of people is reduced at night, and correspondingly, the service provided by the small base station 13 is also reduced. Therefore, the small cell 13 can be managed by the remote management system in a timed or non-timed manner. The resource can be reasonably utilized by the timing or non-timing management of the small base station through the remote management system, and the energy-saving effect is achieved.
