Fig. 2 is a schematic flow chart of a 5G core network hot standby method according to an embodiment of the present invention, and as shown in fig. 2, the method includes the following steps:
step S202, detecting the state of a first server of the overground core network, wherein the first server is a host server in the mine special network.
The 5G core network product in the embodiment of the application can adopt miniaturized equipment, is suitable for a production environment with space limitation, and meets the requirement of intrinsic safety in a mine, the 5GC and the IMS system can be arranged on a universal X86 and ARM platform server in a combined mode, the power of the equipment can meet the requirement of intrinsic safety through light-weight capacity design, the power supply of the equipment adopts 18V, and the integral power is not higher than 18W.
It should be noted that, in the present application, when the active-standby switching of the core network servers is implemented, a keepalive d tool may be used, the keepalive d is a lightweight-level high-availability solution under linux, and detects the state of each machine according to a third layer, a fourth layer, and a fifth layer switching mechanism of a TCP/IP reference model, if a certain machine node is abnormal or works fail, the keepalive d will detect, and remove the failed server node from a cluster system, all the works are automatically completed without manual intervention, the keepalive further includes a function of a VRRP (virtual Router Redundancy Protocol), and a purpose of the VRRP appearing is to solve a single point failure problem occurring in a static route, and the network may be implemented to operate stably through the VRRP without interruption. KeepaliveD may remove the failed machine from the server cluster in the entire mine private network and assign virtual IP to the high priority backup, which becomes the new host. However, the problem of insufficient reliability exists when the main/standby switch is performed by simply adopting KeepaliveD, so that the application provides a method of introducing a preset script to improve the reliability in the hot standby switch process.
In addition, the mine dedicated network may be a local area network specially used for a mine production site, and the network is used for connecting and managing fixed production equipment, movable equipment, communication tools, security tools, terminal equipment of operators and the like in the mine production site, and the mine dedicated network supports 5G communication and also can support 4G communication or Wifi communication, which is not limited herein.
And step S204, under the condition that the first server is detected to be in an abnormal state, executing a switching host script preset in the second server by the second server of the mine core network, and switching the second server serving as a standby server in the mine special network into a host server.
As an alternative embodiment, the second server may be switched to the host server as follows: the second server calls a host switching script from the configuration file of the second server, and deploys a host server running environment in the second server; deactivating a data backup function of the second server according to the switching host script, wherein the data backup function is used for controlling the standby server to acquire synchronous data from the host server; and starting the scheduling server in the second server according to the switching host script, and starting the second server as a host server.
Step S206, the first server executes a standby machine switching script preset in the first server, and switches the first server to the standby machine server.
As an alternative embodiment, the step of executing, by the first server, a standby machine switching script preset in the first server to switch the first server to the standby machine server includes the following steps: the first server calls a switching standby script from the configuration file of the first server, and starts a data backup function of the first server; and according to the standby machine switching script, the scheduling server in the first server is deactivated, and the first server is switched to the standby machine server.
As an optional embodiment, in the above step, the scripts that need to be called from the master to the slave or from the slave to the master may be respectively specified in the keepalive d configuration file (keepalive.
Switching the standby script: notify _ master "/etc/keepalive/fs _ master.
Switching the host script: notify _ backup "/etc/keepalive/fs _ slave.
Therefore, when the primary and standby machines are switched, the keepalived can automatically call the corresponding script, for example, fs _ master.
And step S208, under the condition that the first server is detected to be recovered to the normal state from the abnormal state, switching the first server of the overground core network back to the host server in the mine special network, and switching the second server of the underground core network back to the standby server in the mine special network. In a server hot standby application scene of a core network in a mining area, because the work of the overground core network is more convenient and efficient, the server in the overground core network usually executes the function of a host server, only when the host server in the overground core network has an abnormal condition, a second server serving as a standby machine in the underground core network (also called an underground core network) is temporarily switched into the host server, and a host scheduling task is temporarily executed to serve as the host server; when the first server in the local upper core network returns to normal, the first server can be switched back to the host server as soon as possible, and the problem that the overall performance of the network is reduced for a long time due to the fact that the second server in the mine lower core network is adopted as the host server in the whole mine special network for a long time is avoided.
Optionally, when the first server of the above-ground core network needs to be switched back to the host server in the mine dedicated network and the second server of the mine core network needs to be switched back to the standby server in the mine dedicated network, the first server may also call a switching host script preset in the first server, and the second server calls a switching standby script preset in the second server, so as to implement switching of the preparation states of the servers. In this optional embodiment, the first server and the second server may respectively preset a whole set of main/standby switching scripts, so as to implement free switching of the main/standby machines.
Through the steps, by adopting the mode of presetting scripts in the 5G core network server, the purpose of reliably switching the main standby state of the first server and the second server is achieved by respectively calling the switching standby script preset in the first server and the switching host script preset in the second server serving as the standby server when the first server serving as the host server is detected to be in an abnormal state, so that the technical effect of improving the reliability of the hot standby switching of the underground 5G core network and the ground 5G core network is realized, and the technical problem of unreliable hot standby switching of the underground 5G core network and the ground 5G core network caused by the defect of the existing hot standby scheme is solved.
As an alternative embodiment, the method further comprises: after the second server is switched to be the host server and the first server is switched to be the standby server, the second server generates a MySQL database table at regular time, wherein the MySQL database table is used for recording at least one of the following files: a registration information file, a configuration information file and an account opening information file; the second server imports the MySQL database table into the sql file; and the second server sends the registration information file, the configuration information file and the sql file to the first server, and the first server performs backup according to the data backup function.
In this optional embodiment, the registration information file and the configuration information file may be used to record registration information and configuration information of the host server and software and scripts in the server, and may also be used to record user account opening information of field workers who are used by the mine private network for service, such as a phone card account number of a mine private mobile terminal of the worker, a phone account in a coal mine private network, and the like. In the related art, the information adopts the data transmission synchronization function of MySQL when performing primary and standby synchronization, so that the risk of data mistransmission or data transmission failure exists, and the data synchronization is not stable. By adopting the method provided by the optional embodiment, the key data is imported into the sql file and the sql file is transmitted between the main server and the standby server, so that the data can be stably synchronized from the original host server to the standby server, and the necessary configuration data and service data serving as the host server are not lacked when the standby server is switched to the host server.
As an alternative embodiment, the importing, by the second server, the MySQL database table into the sql file includes: and the second server calls a syncServer script included in the switching host script, starts an rsync daemon process according to the syncServer script, and regularly exports the MySQL database table to the sql file.
As an alternative embodiment, the second server sends the registration information file, the configuration information file, and the sql file to the first server, and the first server performs backup according to the data backup function, including: the first server calls a syncClient script included in the switching standby script, and regularly calls an rsync client to request a second server for data backup according to the syncClient script; the second server responds to a data backup request sent by the second server and sends the registration information file, the configuration information file and the sql file to the first server; and the first server imports the received SQL file into an SQL database of the first server according to the syncClient script.
Fig. 3 is a timing diagram of data backup in active-standby switching of a 5G core network according to an alternative embodiment of the present invention, where during data backup, registration information is required to be uninterrupted and configuration information is synchronized after active-standby switching, so that it is determined that the following content needs to be synchronized: data for recovery registration, data stored in AUSF, synchronized once in 30 seconds. Configuration files for network management configuration, stored under UDM, are synchronized every 3 minutes. Configuration data for network management configuration is stored in UPF and synchronized every 3 minutes.
All synchronization is that the host is responsible for generating files at regular time, the standby machine acquires files from the server at regular time (through virtual IP), and the standby machine can directly acquire configuration files and db files, but the mysql database table needs the host to import the table to be synchronized into the sql file, and after the standby machine acquires the table, the sql file is imported into the local database through mysql dump.
The primary and standby synchronization adopts an rsync scheme, and as a host, a path capable of being synchronized and a synchronous authentication password need to be specified in a configuration file, and then a daemon (rsync-daemon) is started to wait for the standby machine to actively acquire a file; as a standby machine, the rsync client needs to be called regularly to synchronize files.
Synchronization is performed by two scripts, one is a syncServer, the synchronization is only started in a host, and is in charge of starting an rsync daemon process, and exporting the mysql table to the sql file at regular time, the recovery table is once every 3 seconds, and the other tables are once every 3 minutes. The other is syncClient which is only started at the standby machine and is responsible for synchronizing the data of the host machine to the local at regular time and importing the sql file into the mysql database. These two scripts are automatically called in fs _ master.sh and fs _ slave.sh as described above.
In the service, after the standby machine is switched to the host machine, the service is restarted and the configuration file is loaded, so that the standby machine runs the latest configuration in reality, but user data (registration state, online state, call state and the like) and service data (call service, conference service and the like) need to be actively recovered by the scheduling server.
In the current IMS service, most voice services are based on the sip protocol and the RTP protocol, both protocols are based on UDP, and after switching between the main and standby devices, the standby device binds a virtual IP, so that an original UDP packet can be normally sent to the standby device, and then the standby device acquires an IP and a port of an opposite party of a certain service from recovered user data, and re-creates a UDP session, so that the services can be connected.
Fig. 4 is an architecture diagram of a core network provided according to the related art, and as shown in fig. 4, a 5G network node (network element) in the core network may include the following functional modules: AMF: access and Mobility Management Function module, which executes Access control and Mobility Management Function in MME; SMF: session Management Function, which is equivalent to the aggregation of Session Management Function, SGW-C and PGW-C functions in MME; AUSF: the Authentication Server Function Authentication Server Function is matched with the UDM to be specially responsible for the relevant processing of user Authentication data; and (2) UDM: the Unified Data Management is responsible for Unified processing of foreground Data, including user identification, user subscription Data, authentication Data and the like; UPF: user plane Function, which is responsible for data forwarding; PCF: policy Control Function.
After the main and standby servers in the server cluster of the mine private network are switched, the registration information is required to be uninterrupted, the configuration information is also synchronous, the following data for synchronization can be respectively stored in the functional modules in the following mode for recovering the registered data, and the data are stored in the AUSF and synchronized once every 30 seconds; the configuration file for network management configuration is stored below the UDM and is synchronized every 3 minutes; configuration data for network management configuration is stored in UPF and synchronized every 3 minutes.
