Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
Example one
Referring to fig. 1, a flowchart illustrating steps of a method for switching between a master server and a standby server according to an embodiment of the present invention is shown, which may specifically include the following steps:
step 101: a first file transfer rate of a host server interface is obtained.
The embodiment of the invention can be applied to an OMC operation maintenance system, and the OMC can be used for managing all eNBs. In the management of the eNB network element, it is necessary to acquire various file information such as a performance original file, an MR original file, a signaling file, and the like of the eNB. And the eNB network element transmits the file information to the server in a periodic form within basically the same period of time.
The system is provided with a main server and a standby server in advance, where the main server and the standby server may be FTP servers, and the FTP servers are computers providing file storage and access services on the internet, and of course, the main server and the standby server may also be other types of servers, which is not limited in this embodiment of the present invention.
The main server may be used to receive various file information transmitted by the eNB. The OMC may detect a first file transfer rate of the main server interface in real time. A detection timer may also be preset, and when the set interval time is reached, the first file transmission rate of the host server interface is detected once, which is not limited in the embodiment of the present invention.
It can be understood that the OMC detecting the file transfer rate of the main server interface is a mature technology in the field, and any scheme in the prior art that can detect the first file transfer rate of the main server interface can be applied to the present invention, and the embodiments of the present invention are not described herein again.
After the first file transfer rate of the host server interface is obtained, step 102 is performed.
Step 102: and sending a wake-up command to the standby server under the condition that the first file transmission rate is greater than the file transmission congestion threshold.
The OMC system stores a file transmission congestion threshold corresponding to the main server in advance, the file transmission congestion threshold of the main server is obtained by research and development personnel according to actual experience, and the embodiment of the invention does not describe too much for the setting mode of the file transmission congestion threshold.
After obtaining the first file transfer rate of the primary server interface, the first file transfer rate may then be compared to a file transfer congestion threshold.
And when the first file transmission rate is less than or equal to the file transmission congestion threshold, the situation that the master server receives the file sent by the eNB is normal, and the situation that the file transmission congestion does not occur, the OMC continues to detect the first file transmission rate of the interface of the master server.
When the master server receives the eNB normally, the standby server corresponding to the master server is in a standby state. And under the condition that the first file transmission rate is greater than the file transmission congestion threshold, the situation that the number of the eNB sending files received by the main server interface is too large and file transmission congestion may occur is indicated, an awakening command is sent to the standby server corresponding to the main server by the OMC, and the awakening command can be used for indicating the standby server to enter an awakening state from a standby state.
After sending the wake-up command to the standby server, step 103 is performed.
Step 103: and receiving a response message for entering the awakening state returned by the standby server.
After the standby server receives the wake-up command sent by the OMC, the standby server may enter the wake-up state from the standby state according to the wake-up command, and after the standby server enters the wake-up state, a response message corresponding to the wake-up command may be generated and returned to the OMC.
After receiving the response message of entering the wake-up state returned by the standby server, the OMC executes step 104.
Step 104: and selecting at least one base station from a plurality of base stations connected to the main server by the file transmission link according to a preset rule.
The base station with the file transmission link connected to the main server means that a file transmission link protocol, such as an FTP protocol, is established between the base station and the main server, and then a normal file transmission process can be performed between the base station and the main server according to the file transmission link protocol.
In the OMC system, base station identifiers of a plurality of base stations connected to the main server by each file transmission link are pre-stored, and the base station identifiers may be digital identifiers, such as "1", "5", "6", and the like, or may be in other forms. The base station identification of each base station is unique, and a plurality of base stations which are connected to the main server through the file transmission link can be obtained through the pre-stored base station identification.
It should be understood that the above examples are only examples for better understanding of the technical solutions of the embodiments of the present invention, and are not to be construed as the only limitations of the present invention.
Of course, in the prior art, a person skilled in the art may also use other methods to obtain multiple base stations where the file transmission link is connected to the main server, and the embodiments of the present invention are not described in detail herein.
In the embodiment of the present invention, the preset rule may be a file non-transmission rule, and the master server does not currently receive a file uploaded by a certain eNB, for example, if the master server does not receive a file uploaded by eNB3, eNB3 is the selected base station.
The preset rule may also be a percentage threshold that the number of files needs to reach the total number of enbs that are transmitting files, that is, the number of files that the eNB transmits to the main server reaches a set percentage of the total number that needs to be uploaded, for example, the set percentage is 50%, the total number of files that the eNB2 needs to upload to the main server is 100, and when 60 files are uploaded, the eNB2 is the selected base station.
In practical applications, other rules may also be used to select the base station, and the embodiment of the present invention is not limited thereto.
Of course, in the embodiment of the present invention, the base station whose file is not transmitted to the main server is preferentially selected as the selected base station, and the rest of the base stations whose files have been uploaded are randomly selected from the base stations.
After selecting at least one base station among the plurality of base stations connected to the main server from the file transmission link according to a preset rule, step 105 is performed.
Step 105: transmitting a first link handover command to the at least one base station.
After selecting the at least one base station, the OMC may send a first link switching command to the selected at least one base station, and the first link switching command may be used to instruct the selected at least one base station to switch the file transmission link to the standby server.
And if the eNB transmitting the file is selected, the eNB needs to wait for the eNB to complete the transmission of the file currently being transmitted and then respond to the first link switching command.
After responding to the first link switching command, the base station can switch the file transmission link to the standby server, and further can transmit the file to the standby server, so that the file transmission congestion phenomenon of the FTP host can be relieved or solved.
The embodiment of the invention provides a method for switching a main server and a standby server, which comprises the steps of acquiring a first file transmission rate of an interface of the main server, sending a wake-up command to the standby server under the condition that the first file transmission rate is greater than a file transmission congestion threshold, wherein the wake-up command indicates that the standby server enters a wake-up state, receiving a response message returned by the standby server to enter the wake-up state, selecting at least one base station from a plurality of base stations connected to the main server by a file transmission link according to a preset rule, and sending a first link switching command to the at least one base station, wherein the first link switching command indicates that the at least one base station switches the file transmission link to the standby server. By the scheme provided by the embodiment of the invention, the standby server can be awakened to receive the file transmitted by the selected base station when the file transmission rate of the interface of the main server is seriously reduced, so that the equipment resources can be effectively utilized, the waste of the equipment resources is avoided, the occurrence of file transmission congestion is further reduced, and the file transmission efficiency is further improved.

After the first file transfer rate of the host server interface is obtained, step 202 is performed.
Step 202: and starting a hysteresis timer under the condition that the first file transmission rate is greater than a file transmission congestion threshold.
The OMC system stores a file transmission congestion threshold corresponding to the main server in advance, the file transmission congestion threshold of the main server is obtained by research and development personnel according to actual experience, and the embodiment of the invention does not describe too much for the setting mode of the file transmission congestion threshold.
After obtaining the first file transfer rate of the primary server interface, the first file transfer rate may then be compared to a file transfer congestion threshold.
And when the first file transmission rate is less than or equal to the file transmission congestion threshold, the situation that the master server receives the file sent by the eNB is normal, and the situation that the file transmission congestion does not occur, the OMC continues to detect the first file transmission rate of the interface of the master server.
When the master server receives the eNB normally, the standby server corresponding to the master server is in a standby state. And when the first file transmission rate is greater than the file transmission congestion threshold, indicating that the number of the eNB-sent files received by the main server interface is too large and a file transmission congestion situation may occur, the OMC may start a preset hysteresis timer.
After starting the hysteresis timer, step 203 is performed.
Step 203: and judging whether the first timing time of the hysteresis timer is greater than a first set time.
The OMC system is preset with a first set time, which may be 3min, 5min, and the like, and this is not limited in the embodiment of the present invention.
After the hysteresis timer is started, timing is started, and the magnitude relation between the first timing time of the hysteresis timer and the first set time is judged.

Step 204: and sending a wake-up command to the standby server and closing the hysteresis timer.
And when the first timing time of the hysteresis timer is longer than the first set time, sending a wake-up command to the standby server corresponding to the main server by the OMC, wherein the wake-up command can be used for indicating the standby server to enter a wake-up state from a standby state.
After the wake-up command is sent by the OMC to the standby server, the hysteresis timer is turned off by the OMC and step 205 is performed.
Step 205: and receiving a response message for entering the awakening state returned by the standby server.
After the standby server receives the wake-up command sent by the OMC, the standby server may enter the wake-up state from the standby state according to the wake-up command, and after the standby server enters the wake-up state, a response message corresponding to the wake-up command may be generated and returned to the OMC.
After receiving the response message of entering the awake state returned by the standby server, the OMC executes step 206.
Step 206: and selecting at least one base station from a plurality of base stations connected to the main server by the file transmission link according to a preset rule.
The base station with the file transmission link connected to the main server means that a file transmission link protocol, such as an FTP protocol, is established between the base station and the main server, and then a normal file transmission process can be performed between the base station and the main server according to the file transmission link protocol.
In the OMC system, base station identifiers of a plurality of base stations connected to the main server by each file transmission link are pre-stored, and the base station identifiers may be digital identifiers, such as "1", "5", "6", and the like, or may be in other forms. The base station identification of each base station is unique, and a plurality of base stations which are connected to the main server through the file transmission link can be obtained through the pre-stored base station identification.
It should be understood that the above examples are only examples for better understanding of the technical solutions of the embodiments of the present invention, and are not to be construed as the only limitations of the present invention.
Of course, in the prior art, a person skilled in the art may also use other methods to obtain multiple base stations where the file transmission link is connected to the main server, and the embodiments of the present invention are not described in detail herein.
In the embodiment of the present invention, the preset rule may be a file non-transmission rule, and the master server does not currently receive a file uploaded by a certain eNB, for example, if the master server does not receive a file uploaded by eNB3, eNB3 is the selected base station.
The preset rule may also be a percentage threshold that the number of files needs to reach the total number of enbs that are transmitting files, that is, the number of files that the eNB transmits to the main server reaches a set percentage of the total number that needs to be uploaded, for example, the set percentage is 50%, the total number of files that the eNB2 needs to upload to the main server is 100, and when 60 files are uploaded, the eNB2 is the selected base station.
In practical applications, other rules may also be used to select the base station, and the embodiment of the present invention is not limited thereto.
Of course, in the embodiment of the present invention, the base station whose file is not transmitted to the main server is preferentially selected as the selected base station, and the rest of the base stations whose files have been uploaded are randomly selected from the base stations.
After selecting at least one base station among the plurality of base stations connected to the main server from the file transmission link according to a preset rule, step 207 is performed.
Step 207: saving the at least one base station to a link switching list.
A link switching list may also be preset in the OMC system, where the link switching list may store the selected at least one base station, and the link switching list may store a base station name or a base station identifier of the selected at least one base station, and the like.
After saving the selected at least one base station to the link switching list, step 208 is performed.
Step 208: transmitting a first link handover command to the at least one base station.
After selecting the at least one base station, the OMC may send a first link switching command to the selected at least one base station, and the first link switching command may be used to instruct the selected at least one base station to switch the file transmission link to the standby server.
And if the eNB transmitting the file is selected, the eNB needs to wait for the eNB to complete the transmission of the file currently being transmitted and then respond to the first link switching command.
After responding to the first link switching command, the base station can switch the file transmission link to the standby server, and further can transmit the file to the standby server, so that the file transmission congestion phenomenon of the FTP host can be relieved or solved.
Step 209 is performed in transmitting a first link handover command to the selected at least one base station.
Step 209: and starting the hysteresis timer under the condition that the first file transmission rate is less than or equal to the file transmission congestion threshold.
In the embodiment of the present invention, the OMC always detects the first file transmission rate of the interface of the main server during and after the switching of the main server and the standby server, and starts the hysteresis timer when the detected first file transmission rate is less than or equal to the file transmission congestion threshold and indicates that the file sent by the eNB and received by the main server is recovered to normal, thereby performing step 210.
Step 210: and judging whether the second timing time of the hysteresis timer is greater than a second set time.
The second set time is preset in the OMC system, and the second set time may be 3min, 5min, and the like, which is not limited in the embodiment of the present invention.
And starting timing after the hysteresis timer is started, and judging the magnitude relation between the second timing time of the hysteresis timer and the second set time.
When the second timing time of the hysteresis timer is greater than the second set time, step 211 is executed.
Step 211: sending a second link switch command to at least one base station in the link switch list.
When the second timing time of the hysteresis timer is greater than the second set time, the OMC may send a second link switching command to at least one base station in the link switching list, where the second link switching command may be used to instruct the at least one base station to switch the file transmission link to the main server.
Step 212 is performed after sending the second link switch command to the at least one base station in the link switch list.
Step 212: and receiving a return message of switching the file transmission link returned by the at least one base station to the main server.
After at least one base station in the link switching list receives the second link switching command, when a certain base station is transmitting a file to the standby server, the base station needs to wait for the completion of the transmission of the file being transmitted, and then respond to the second link switching command to switch the file transmission link of the base station to the main server.
And when the base station does not perform file transmission with the standby server, the file transmission link of the base station is switched to the main server by directly responding to the second link switching command.
And after the base station switches the file transmission link to the main server, generating a return message for switching the file transmission link to the main server, and sending the return message to the OMC.
The OMC receives a return message of switching the file transmission link returned by at least one base station to the main server, and executes step 213.
Step 213: and sending a standby command to the standby server.
After receiving a return message from the main server to which the file transmission links returned by all the base stations in the link switching list are switched, the OMC may send a standby command to the standby server, where the standby command may be used to instruct the standby server to enter a standby state, and after receiving the standby command, the standby server switches the awake state to the standby state according to the instruction command.
