Detailed Description
For the purposes, technical solutions and advantages of the present application, the technical solutions of the present application will be clearly and completely described below with reference to specific embodiments of the present application and corresponding drawings. It will be apparent that the described embodiments are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present application based on the embodiments herein.
Referring to fig. 1, a method for managing a small cell according to an embodiment of the present application specifically includes the following steps:
and S100, configuring the wireless device at least one small base station.
Further, in a preferred embodiment provided in the present application, in the case of rapid development of communication technology, the application of the present application is very wide, whether the 4G small base station 13 is deployed in a large number or the 5G small base station 13 is deployed in a small number. The small cell 13, which is known per se, basically adopts the conventional tr069 protocol or the snmp protocol. the tr069 protocol or the snmp protocol manages the configuration, alarms, and performance of the small base station 13. Considering the characteristics of the 5G frequency band and the actual use condition of indoor places, the deployment basically needs to be carried out in a dense networking mode. Because the management of the small base station 13 cannot achieve the ideal state of real accurate dead angle-free dynamic control anytime and anywhere, a wireless device is selected to be configured in the small base station 13, so that the small base station 13 realizes multidirectional management of the small base station 13 under the action of the wireless device.
The wireless device, namely the Ble module 12 (bluetooth low energy module). The Ble module 12 is a very commonly used wireless communication module supporting bluetooth protocol 4.0 or higher. The biggest characteristic is cost and power consumption reduction, and the method is applied to products with high real-time requirements and low data rate. Compared with the traditional Bluetooth technology, a new function added by the low-power Bluetooth technology is a broadcasting function. By this function, the slave device can tell that it needs to send data to the master device. Bluetooth low energy technology employs a variable connection time interval, which may be set to vary from a few milliseconds to a few seconds depending on the particular application. In addition, because the BLe technology adopts a very fast connection mode, the BLe device can be in a non-connection state (energy saving) and the two ends of the link are only aware of each other, the link is opened only when necessary, and then the link is closed in a time as short as possible. The main applications include: positioning tags, asset tracking, motion and fitness sensors, medical sensors, smart watches, remote controls, toys, etc.
It can be understood that, by configuring the Ble module 12, the small base station 13 can increase a plurality of communication management modes based on the original management, so as to perform multi-directional and multifunctional management on the small base station 13. The multifunctional management can be specifically explained as that after the Ble module 12 is configured in the small base station 13, other fault management functions of the small base station 13 can be added on the basis of the management of a remote network management system.
Referring to fig. 2, a block diagram of communication connection of the management small base station 13 according to an embodiment of the present application is provided.
S110, connecting with a remote network management system or a wireless device control end according to the small base station configured by the wireless device.
The control end of the wireless device, i.e. the control of the Ble module 12, may be a mobile phone with a bluetooth module, a computer, or other devices capable of transmitting wireless network protocols. The wireless device control terminal is a BLE control switch 14 in the embodiment of the present application.
Further, in a preferred embodiment provided in the present application, the 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 cell 13 establishes a first type of connection with the remote network management system 10 via 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 via a wireless transmission protocol.
It can be understood that after the Ble module 12 is configured in the small bs 13, the original connection mode of the small bs 13 is still unchanged, that is, the small bs 13 and the remote network management system 10 establish the first type of connection through the wireless transmission protocol. The second type of connection is that after the Ble module 12 is configured in the small base station 13, the Ble module 12 is connected with the remote network management system 10 or the Ble control switch 14, so that other functions of managing faults of the small base station 13 are added.
Further, in a preferred embodiment provided in the present application, the small base station 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 a connection to the remote network 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 tasks: the user equipment is automatically configured and dynamically configured. Management of software and firmware of user equipment. The status and performance of the user equipment are monitored. Diagnosis of communication failure.
It should be noted that the remote network management system 10 may be a computer, a mobile phone, or other software having a function of a wireless transmission protocol device. Computers, cell phones or other device software with wireless transmission protocols perform 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 small base station 13 is added with the function of managing faults.
Specifically, on the basis of the management of the small base station 13 by the remote network management system 10, the small base station 13 is also controlled by the Ble module 12 by configuring the Ble module 12 to the small base station 13. That is, the management mode of the small cell 13 becomes various modes. The management mode of the small base station 13 is diversified by the establishment of various modes.
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 Ble control switch 14. The method specifically comprises the following steps: the Ble module 12 establishes one of the second type of connection with the Ble control switch 14 via a wireless transmission protocol. The Ble module 12 establishes a second one of the second type of connection with the remote network management system 10 via a wireless transmission protocol.
It should be noted that the second type of connection established by the Ble module 12 with the remote network management system 10 or the Ble control switch 14 is required to pass through the Ble mesh gateway 11.Mesh networks, i.e., wireless Mesh networks, are multi-hop (multi-hop) networks, which are one of the key technologies to solve the "last kilometer" problem. In the evolution towards the next generation network, wireless is an indispensable technology. The wireless mesh can cooperatively communicate with other networks, is a dynamic network architecture which can be continuously expanded, and any two devices can keep wireless interconnection. The Ble module 12 is a wireless communication protocol stack used by bluetooth mesh. While bluetooth mesh is not a wireless communication technology, but a network technology. Bluetooth mesh networks rely on low power bluetooth BLe. In the bluetooth Mesh network, low power consumption nodes can achieve the purpose of low power consumption by reducing the duty cycle of the radio frequency transceiver (RF transceiver) on, and the low power consumption nodes only turn on the radio frequency transceiver when message transmission and reception are needed, and are in a dormant state at other times. In bluetooth Mesh networks, a further class of nodes is dedicated to low power nodes, which have a Friend property, which may also be referred to as Friend nodes. The Friend node and the low power node may establish a Friend relationship. After the relation is established, the Friend node can temporarily store information sent to the low-power-consumption node, and after the low-power-consumption node exits from the sleep mode, the related information is retrieved from the Friend node.
There are various routing methods for the Ble mesh. The CSR Mesh networking technology based on Bluetooth 4.0 adopts the simplest and most reliable flooding type routing algorithm. The basic idea of the flooding routing algorithm is that each node forwards the received data packet by using broadcast, the distance between the nodes is 50m, and the destination node is finally reached by continuous one-stage 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, the optimal node is selected from the group of nodes, and then the optimal node is forwarded to the next group of nodes, so that the data packet is received by repeating the process to a destination node, and the success rate of data packet transmission can be greatly improved.
Further, in a preferred embodiment provided herein, the Ble module 12 and Ble control switch 14 establish a first one of the second type of connection via the Ble mesh protocol.
Specifically, the BLE control switch 14 controls the BLE module 12 through the BLE mesh protocol. After receiving the Ble control switch 14 command, the Ble module 12 sends a command to the small base station 13. After receiving 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 piece of software on a notebook computer, a cell phone, or a device with wireless transmission protocol capability. Software on a notebook computer, a mobile phone, or a device with wireless transmission protocol functions controls the plurality of small base stations 13. In the specific embodiment of the application, when a single-point device fails or a site manager needs to control the single device, the site manager can perform precise control through a mobile phone or a Bluetooth APP on a device with a wireless transmission protocol function.
Further, in a preferred embodiment provided herein, the Ble module 12 establishes a second one of the second type of connection with the remote network management system 10 via a wireless transmission protocol. The Ble module 12 is configured in the small cell 13, and the remote network management system 10 is the 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 through the Ble mesh protocol. The protocol converter is connected with the remote network management system 10 through tcp transmission protocol. Through the connection among 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 corotators, are also called interface converters. The method can enable hosts which are positioned on a communication network and adopt different high-layer protocols to still cooperate with each other, so as to finish 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 Ethernet or V.35 data interface of IEEE802.3 protocol to 2M interface of standard G.703 protocol. The conversion CAN also be performed between a 232/485/422 serial port and an E1, CAN interface and a 2M interface. Protocol conversion is a mapping, that is, mapping a sequence of transception information (or events) of one protocol to a sequence of transception information of another protocol. The information that needs to be mapped is important information, so the protocol conversion can be regarded as a mapping between important information of two protocols. The important information and the non-important information are relatively speaking, and different converters are obtained by selecting different important information to map according to specific needs.
It should be noted that in the second communication mode of the second type of connection, the protocol converter is the Ble mesh gateway 11. 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, the small base station 13 and the first type connection and the second type connection are formed. In the state that the first type connection and the second type connection are in operation, the Ble modules 12 of the mesh network, which are respectively configured in the small base station 13, can also be connected to each other to serve as a repeater. Mesh networks, i.e., wireless Mesh networks, are multi-hop (multi-hop) networks, which are one of the key technologies to solve the "last kilometer" problem. In the evolution towards the next generation network, wireless is an indispensable technology. The wireless mesh can cooperatively communicate with other networks, and is a dynamic network architecture which can be continuously expanded. 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, a first type of connection and a second type of connection are formed among the Ble module 12, the Ble control switch 14, the small base station 13, and the remote network management system 10. The first type connection and the second type connection perform fault management on the small base station 13 in multiple modes.
Further, in a preferred embodiment provided herein, 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 base station 13 is achieved. Specifically, the connection between the small base station 13 and the remote network management system 10 is the first type, and for the small base station 13, the connection 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 base station 13.
It should be noted that the first type of connection manages the faulty interface that the small base station 13 has to make, i.e. through the remote network management system 10. In the face of a specific failure, the remote network management system 10 is required to remotely control or maintain the small base station 13 in the field to solve the problem. Specific faults which can be solved by the remote control include various fault problems such as TRX frequency band and frequency point mismatch alarm, standing wave ratio alarm, wireless link prompt alarm and the like. The remote network management system 10 handles the above-described failure occurring in the small cell 13. For example, alarms for radio link cues are:
channel activation anomaly alert: the main reason for this failure is that the bsc and the channels inside the base station are inconsistent, so that the log and the signaling tracked by the carrier maintenance station can be obtained, and the feedback problem is solved.
Channel abnormal release prompt alarm: and performing radio frequency loop-back test to observe whether uplink code is available. The phone system is viewed. The data configuration is checked. Look at sdcch performance measurement session. An uplink frequency bin scan is used. And replacing the carrier frequency position. It is checked whether the tightly covered cell is erroneously accessed. And acquiring field information.
The main bcch has no traffic prompt alarm: the operation steps are the same as the abnormal release prompt alarm of the channel, and the difference is the problem of the bcch carrier frequency.
And (5) uplink and downlink balance prompt alarm: the level imbalance of the uplink and downlink signals requires checking the uplink channel and the downlink channel.
Further, in a preferred embodiment provided herein, the small cell 13 establishes a second type of connection with the remote network management system 10. Through the second type of connection, remote fault management of the small base station 13 is achieved. Specifically, the small cell 13 is connected to the second type of connection established by the remote network management system 10 or the BLE control switch 14. The management interface is mainly used for managing abnormal hanging and death occurring at least including the small base station 13. .
It should be noted that the small cell 13 establishes a second type of connection with the remote network management system 10 or the BLE control switch 14, because the small cell 13 cannot resolve the failure through the first type of connection in case of abnormal suspension. 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 management personnel is not needed. Meanwhile, the device with the fault may also be controlled by a fault site manager using an app on the device with the BLE control switch 14. The problem that the small base station 13 is abnormally hung up is solved through the two modes, and field management personnel are not required to carry out field maintenance in the past.
Further, in a preferred embodiment provided in the present application, remote fault management is performed on the small base station 13 through connection, and specific location information of the small base station 13 with the fault may be specifically determined.
It can be understood that the remote network management system 10 can accurately obtain the specific location of the small cell 13 through the Ble mesh gateway 11.
It should be noted that, by means of the connection, the operation state of the small base station 13 can also be controlled in real time according to the service demand state of the small base station 13. In the embodiments provided in this application, it is necessary for many office buildings to be present. Most staff in the office building on the daytime is vigorous in the amount of service provided by the small base station 13, and the flow of people at night is reduced, and correspondingly, the service provided by the small base station 13 is also reduced. Thus, the small cell 13 may be managed with or without timing by a remote management system. The resource can be reasonably utilized by the remote management system for the timing or non-timing management of the small base station, so that the energy-saving effect is achieved.
It should also be noted that the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
