Therefore, for different core networks, the mobile communication network provided in this embodiment may be a 4G mobile communication network, a 5G mobile communication network, or a hybrid communication network.

Alternatively, the network access device may be, for example, a 4G base station or a 5G base station (the next Generation Node B, abbreviated as gNB) or the like, corresponding to the core network.

In practice, in order to ensure the normal provision of services in a private sub-network, real-time monitoring of the operation states of various network devices in the private sub-network is required. At this time, the method provided by the following embodiments of the present invention may be used to implement real-time monitoring of the operation state of the network device by the control server deployed in the public sub-network.

Based on the above description, fig. 2a is another communication network according to an embodiment of the present invention. As shown in fig. 2a, the communication network may further comprise proxy devices deployed in the private sub-network, on the basis of the embodiment shown in fig. 1 a. Similar to fig. 1a, three types of network devices are also schematically shown in fig. 2a, and the number of network device types is not limited by the embodiments of the present invention. The communication network shown in fig. 2a is also a mobile communication network and the operation of the mobile communication network can be described in particular as:

the proxy device in the private sub-network may collect the respective operation data of the different types of network devices in the private sub-network and send the operation data to the control server in the public sub-network. The control server may store the respective operational data of the different types of network devices in response to receipt of the operational data, such as storing the operational data in its own database. The control server may then monitor the respective operating states of the different types of network devices in the private sub-network based on the stored operating data. When an abnormality is detected in a certain network device, a control instruction for the abnormal network device can be further generated and sent to the abnormal network device. Finally, the abnormal network device can execute the control instruction to restore itself to normal, that is, to make the control server in the public sub-network realize the operation and maintenance of the network device in the private sub-network.

Alternatively, the proxy device may call a data collection interface of the network device to collect the respective operation data of the different types of network devices. Optionally, the operational data collected by the proxy device may include configuration data and/or status data of the network device. Alternatively, the configuration data may be written in a configuration file of the network device and the status data may be written in a log of the network device. The control server may determine whether the network device is abnormal through analysis of the status data of the various network devices to generate control instructions to implement the device operation. Optionally, the control instruction may be used to control the network device to restart, and may also be used to modify a configuration parameter of the network device, and so on.

Alternatively, the communication network shown in fig. 2a may be modified to fig. 2b, when the network devices included in the private sub-network in the communication network shown in fig. 2a may specifically include CPE, a network access device, a core network device, and a server. And different types of network devices may have different operational data.

In particular, when the network device is a CPE, the configuration data may include an IP address of the CPE, a network segment of a virtual local area network (Virtual Local Area Network, abbreviated as VLAN) to which the CPE accesses, an access number of the CPE, and a data network name (Data Network Name, abbreviated as DNN) to which an application server providing a target service used by the CPE belongs. The state data can be the flow of the CPE, namely the data quantity sent and received after the CPE is accessed to the special sub-network; resource usage of the CPE may also be included, such as computing resources, memory resources, hard disk resources, etc.; the number of load devices of the CPE may also be included. The load device may be considered as a device that connects the CPE as an access point and accesses the private sub-network.

When the network device is a base station, the configuration data may include configuration parameters of a Physical (PHY) layer, a medium access control (Media Access Control, abbreviated MAC) layer, a radio link control layer protocol (Radio Link Control, abbreviated RLC) layer, a packet data convergence protocol (Packet Data Convergence Protocol, abbreviated PDCP) layer, and a radio resource control (Radio Resource Control, abbreviated RRC) layer; the method can also comprise the bandwidth, the antenna, the frequency band and the frequency point used by the base station; and may also include carrier spacing of the base station, cell switch threshold, etc. The state data can be the flow of the packet base station, namely the data quantity sent and received after the base station is accessed to the special sub-network; and may also include the resource usage of the base station, such as the usage of air interface resources.

When the network device is a core network device, the configuration data may include a cell identifier corresponding to the core network device, a public land mobile network (Public Land Mobile Network, abbreviated as PLMN), a slice identifier, a DNN configuration, a domain name system (Domain Name System, abbreviated as DNS), an authentication parameter, and the like. The status data may include the traffic of the core network device, i.e. the amount of data sent and received by the core network device during operation of the private sub-network; resource usage of the core network device such as computing resources, memory resources, hard disk resources, etc. may also be included; the usage status of the core network device, such as registration success rate, paging success rate, handover success rate, etc., of the CPE may also be included.

When the network device is an application server, the configuration data may include an IP address of the application server, a port number, and a service type of a service provided by the application server. The status data may include traffic of the application server, i.e., the amount of data transmitted and received during the process of providing the target service by the application server; and may also include resource usage of the application server, such as computing resources, memory resources, hard disk resources, and the like.

In this embodiment, the mobile communication network may include a public sub-network in which the control server is disposed and a private sub-network in which different types of network devices are disposed. Based on the network structure, the control server can receive and store the operation data of different types of network devices in the private sub-network, which are collected by the proxy device, and monitor the operation state of the network devices according to the operation data. When the network equipment is monitored to be abnormal, a corresponding control instruction can be sent to the abnormal network equipment, namely, the operation and maintenance of the network equipment are realized.

Based on the operation of the communication network described in the embodiments shown in fig. 2a or fig. 2b, the main operations of the proxy device include collecting operational data and transmitting operational data, which may alternatively be performed by a collecting component and a transmitting component in the proxy device, respectively. Specifically, the acquisition component is used for acquiring the operation data of different types of network equipment, and the sending component is used for sending the acquired operation data to the control server.

Similar to the proxy device, the main work of the control server includes the storage of the operation data and the generation of the control instructions. The control server may include in particular a controller and a memory. The memory is used for storing the operation data sent by the sending component. The controller is configured to monitor an operational state of the network device based on the operational data stored in the memory. The controller may also generate and send control instructions to the abnormal network device when the network device is abnormal.

Based on the proxy device and the control server with the above structures, on the basis of the embodiment shown in fig. 2b, the embodiment of the present invention may also provide a further communication network, as shown in fig. 3. The proxy device and the control server in each communication network according to each of the embodiments of the present invention, and the proxy device and the control server according to each of the embodiments of the present invention may have the above-described configuration.

As can be seen from the description of the above embodiments, for any network device to be monitored in the private sub-network, that is, the target network device, the control server may acquire the operation data of the target network device before monitoring the device, and the source identifier of the operation data is needed to be used to acquire the operation data. The target network device may be any one of the different types of network devices mentioned in the above embodiments, for example, any one of CPE, access network device, core network device, and application server. The process by which the proxy component gathers operational data for different types of network devices and adds source identification to the operational data may be described below.

When the target network device is a CPE or a network access device, which is typically a network device in a hardware form (abbreviated as a hardware network device), the proxy device may invoke a data acquisition interface of the target network device to acquire operation data of the target network device. Alternatively, in the mobile communication network, the proxy devices may be in one-to-one correspondence with the hardware network devices, and the proxy devices may be installed in the hardware network devices in the form of software. Meanwhile, as the source identifier needs to indicate which network device the operation data is collected by which proxy device and the one-to-one correspondence between the proxy device and the hardware network device, the proxy device corresponding to the target network device can directly determine the first device identifier of the proxy device to be the source identifier of the operation data of the target network device, and add the first device identifier to the operation data.

When the target network device is an application server or a network device such as a core network device, which is typically represented in a software form (simply referred to as a software network device), a plurality of software network devices of the same type as the target network device may constitute one network device cluster, and at least one network device cluster may be deployed in the same hardware device. In this case, the proxy devices may correspond one-to-one to the network device cluster. Alternatively, the proxy device may be installed in the same hardware device as the network device cluster in the form of software. The proxy device corresponding to the network device cluster to which the target network device belongs may call the data acquisition interface of the target network device in the network device cluster to acquire the operation data of the target network device, where the target network device may be any network device in the network device cluster. Meanwhile, the proxy equipment can also call the access interface of the network equipment cluster to acquire the second equipment identification of the target network equipment. Finally, the proxy device may determine the first device identity of itself and the second device identity of the target network device itself as source identities of the operational data collected from the target network device.

When a private sub-network is deployed in the communication network, according to the correspondence between the proxy component and the different types of network devices described in the above two cases, the embodiment of the present invention may further provide the communication network shown in fig. 4, and the control server may collect the operation data of each network device in the communication network and add the source identifier for the operation data according to the above described manner.

Alternatively, the number of dedicated sub-networks in the communication network may be at least one, and the types of network devices included in the respective dedicated sub-networks may be the same or different. Embodiments of the present invention may also provide the communication network shown in fig. 5, based on the type of network device comprised in the embodiment shown in fig. 2b, when a plurality of private sub-networks are deployed in the communication network.

Based on the communication network shown in fig. 5, the objective network device and the relative relation between the proxy component and the network device in the embodiment shown in fig. 4 are accepted at the same time, when the objective network device is any hardware network device in any private sub-network, the proxy device corresponding to the objective network device can call the data acquisition interface of the objective network device to acquire the operation data of the device, and meanwhile, the network identifier of the private sub-network where the objective network device is located can be determined. Finally, the proxy device may determine the network identity and the first device identity of the proxy device itself as source identities and add to the operational data of the target network device. Wherein a plurality of private networks may be assigned network identifications during deployment to the mobile communication network. The network identification is associated with a network device in the private sub-network.

When the target network device is any software network device in any special sub-network, the proxy device corresponding to the network device cluster to which the target network device belongs can call the data acquisition interface of the target network device to acquire the operation data of the software network device, and can call the access interface in the network device cluster to acquire the second device identifier of the target network device. And the proxy device may also determine the network identification of the private sub-network in which the target network device is located. Finally, the proxy device may determine the network identifier, the second device identifier of the target network device, and the first device identifier of the proxy device itself as source identifiers, and add the source identifiers to the operation data of the target network device.

When a plurality of private sub-networks are deployed in the communication network, according to the correspondence between the proxy components and the different types of network devices described in the above two cases, the embodiment of the present invention may further provide the communication network shown in fig. 6, and the control server may collect the operation data of each network device in the communication network and add the source identifier for the operation data according to the above described manner. The specific structure of the server cluster and the core network cluster in fig. 6 can be seen from the embodiment shown in fig. 4.

Optionally, according to the characteristics of the state data and the configuration data in the operation data, that is, the change frequency of the state data is high, the change frequency of the configuration data is relatively fixed, the proxy component can also add source identifiers for different types of data at different occasions.

Optionally, the proxy device may collect different types of status data of different types of network devices according to a preset period. Alternatively, different types of status data of different types of network devices may be provided with the same or different preset periods, and the proxy device may perform adding source identification for the status data as a timed task. One type of status data of a network device corresponds to one timing task.

Optionally, the proxy device may also collect different types of configuration data of different types of network devices in response to a configuration operation triggered by the operator on the network device. I.e. the proxy device may perform the addition of source identification for the configuration data as a triggered task. One configuration operation of the operation and maintenance personnel corresponds to one trigger type task.

The above can also be understood in connection with fig. 7. For example, assuming that the proxy device shown in fig. 7 is used to collect operation data of the CPE, the proxy device may collect the traffic of the CPE and the number of load devices by executing tasks 1 to m. Wherein the value of m is equal to the number of types of state data. The proxy equipment can also collect IP addresses, DNNs, computing resource utilization rates, storage resource utilization rates and the like of the CPE through at least tasks m+1 to n. Wherein the value of n-m-1 is equal to the number of types of configuration data.

In the communication network provided in the foregoing embodiments, different types of network devices may be deployed in the private sub-network, and the operation data of these network devices may be stored in the control server in the public sub-network, specifically, in the database deployed by the control server.

The operation data may be stored in a sub-table in the database, i.e. the control server may store the same operation data of the same type of network device in the same data table of the database according to the source identifier of the operation data. Wherein the source of the operational data identifies which network device in which private sub-network the operational data is deployed to indicate which proxy device collected by which network device. The proxy device may respond to the collection of the operation data, add for the collected operation data, and send the operation data with the source identifier to the control server.

The control server may monitor whether each network device in the private sub-network is abnormal using the data table to which the operation data has been written. And because the monitoring process of the control server to any network device in the private sub-network, namely the target device, is the same, the monitoring process can be described by taking the target device as an example:

The controller server may first determine the target device to be monitored from a locally stored list of device connections. And inquiring the operation data of the target equipment from the data table according to the source identification, and monitoring the operation state of the target equipment according to the inquiry result. The device connection relation list reflects communication connection relations among agent devices and network devices in the private sub-network. If the network devices in the private sub-network include CPE, network access device, core network device and application server, fig. 8 shows a schematic diagram of the connection relationship between the devices in the network.

Since the operation data may include configuration data and status data, and as described in the above embodiments, the configuration data and status data of different types of network devices may further include different types, the sub-table storage of operation data may be more specifically: the control server may store any type of status data for the same type of network device in a first data table and any type of configuration data for the same type of network device in a second data table.

In addition, the characteristics of the state data and the configuration data, namely, the change frequency of the state data is high, the configuration data is relatively fixed, and the change frequency is low, so that different types of data can be stored in corresponding data tables in different modes. Alternatively, the control server may write the received first latest data as delta data into the first data table in which the first history data is recorded; the control server may also be arranged to receive the second latest data over the second historical data already recorded in the second data table. Wherein the first history data and the first latest data are any type of data in the status data of the same type of network device, such as the traffic of the CPE. The second history data and the second latest data are any one type of data among configuration data of the same type of network device, such as PHY layer parameters of the network access device.

It can be seen that the control server stores the running data in a sub-table according to the source identification, so that the isolation storage of different types of running data of different types of network data can be realized. That is, each new or updated operation data only relates to one data table, and the data in other data tables is not affected, so that the new or updated operation data is more accurate, and the error storage of the data is avoided.

Optionally, when a plurality of private sub-networks are deployed in the communication network, the base control server may still monitor any network device in any private sub-network in the manner described in the embodiments shown in fig. 2a to 3. In this case, alternatively, for the storage of the operation data, the same operation data of the same type of network device deployed in different private sub-networks may be written in the same data table.

As can be seen from the above description, the communication network provided in the above embodiments may be a 5G mobile communication network, and in this case, the operation and maintenance procedure of the control server on the network device in the private sub-network of the 5G mobile communication network may be illustrated:
