Alternatively, the core network devices may include respective devices required to implement the core network functions. When the core Network device is embodied as software, the core Network device in the form of software may be a Virtualized Network Function module (VNF) deployed in a Network Function Virtualization Infrastructure (NFVI).

The Core Network may be a 5G Core Network (5G Core Network, abbreviated as 5 GC) based on a fifth Generation Mobile Communication Technology (5G), may also be a 4G Core Network based on a 4th Generation Mobile Communication Technology (4G), and may also be a Core Network of a mixture of 4G and 5G. Both the 5G core network and the 4G core network may have a common core network structure, and will not be described in detail herein. Therefore, for different core networks, the mobile communication network provided in this embodiment may specifically 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 (gNB) corresponding to the core network.
In practice, in order to ensure the normal provision of services in the private sub-network, the operation status of various network devices in the private sub-network needs to be monitored in real time. At this time, the method provided by the following embodiments of the present invention can be used to implement real-time monitoring of the operation status 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 provided by the embodiment of the present invention. As shown in fig. 2a, on the basis of the embodiment shown in fig. 1a, the communication network may further comprise a proxy device deployed in a dedicated sub-network. Similar to fig. 1a, fig. 2a only schematically shows three types of network devices, and the number of types of network devices is not limited in each embodiment of the present invention. The communication network shown in fig. 2a is also a mobile communication network, and the operation process of the mobile communication network can be specifically described as follows:
the agent device in the private sub-network may collect operation data of each of the different types of network devices in the private sub-network and transmit the operation data to the control server in the public sub-network. The control server may store the operational data in response to receipt of the operational data for each of the different types of network devices, such as by storing the operational data in its own database. The control server can then monitor the respective operating states of the different types of network devices in the dedicated sub-network on the basis of the stored operating data. When it is monitored that a certain network device is abnormal, 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 command to restore itself to normal, that is, the control server in the public sub-network implements the operation and maintenance of the network device in the private sub-network.
Alternatively, the proxy device may collect the respective operation data of the different types of network devices by calling a data collection interface of the network device. Optionally, the operation data collected by the agent device may include configuration data and/or status data of the network device. Alternatively, the configuration data may be written to a configuration file of the network device and the status data may be written to a log of the network device. The control server may determine whether the network device is abnormal through analysis of the state data of the various network devices to generate a control instruction for implementing the operation and maintenance of the device. Alternatively, the control instruction may be used to control the network device to restart, or may be used to modify the configuration parameters of the network device, and so on.
Alternatively, while in the communication network shown in fig. 2a, the network devices included in the dedicated sub-network may specifically include CPE, network access device, core network device and server, the communication network shown in fig. 2a may be modified to fig. 2b. And different types of network devices may have different operational data.
Specifically, 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 (VLAN) accessed by the CPE, an access number of the CPE, and a Data Network Name (DNN) to which an application server providing a target service used by the CPE belongs. The state data can include the flow of the CPE, namely the data volume sent and received by the CPE after the CPE accesses the special sub-network; the resource utilization rate of the CPE can also be included, such as computing resources, memory resources, hard disk resources, and the like; 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 a dedicated sub-network.
When the network device is a base station, the configuration Data may include configuration parameters of a Physical (PHY) layer, a Media Access Control (MAC) layer, a Radio Link Control (RLC) layer, a Packet Data Convergence Protocol (PDCP) layer, and a Radio Resource Control (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 the carrier spacing of the base station, cell switching thresholds, etc. The state data can include the flow of the base station, namely the data volume sent and received by the base station after the base station is accessed into 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 (PLMN for short), a slice identifier, DNN configuration, a Domain Name System (DNS for short), an authentication parameter, and the like. The status data may include traffic of the core network device, i.e., the amount of data sent and received by the core network device during the operation of the private sub-network; the resource utilization rate of the core network device, such as computing resource, memory resource, hard disk resource, etc., may also be included; the usage status of the core network device may also be included, such as registration success rate, paging success rate, handover success rate, etc. of the CPE.
When the network device is an application server, the configuration data may include an IP address, a port number of the application server, and a service type of a service provided by the application server. The state data may include traffic of the application server, i.e., the amount of data sent 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 so on.
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 equipment in the special sub-network, which is collected by the agent equipment, and monitor the operation state of the network equipment 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.
In the above process, the operation data of each network device in the dedicated sub-network, which is collected by the agent device, may be centrally acquired and stored by the control server, so that the control server may use the stored operation data to monitor the network devices. Meanwhile, the operation data are stored in the local control server, so that the control server does not need to acquire the operation data by sending a call request to the network equipment, but can directly read the operation data from the local control server, that is, the acquisition difficulty and cost of the operation data of the network equipment in the special sub-network are reduced, and the control server can monitor the network equipment in the special sub-network more conveniently and efficiently.
Based on the working process of the communication network described in the embodiment shown in fig. 2a or fig. 2b, the main work of the agent device includes collecting operation data and sending operation data, which may optionally be performed by a collecting component and a sending component in the agent 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 agent device, the main job of the control server includes storage of operation data and generation of control instructions. The control server may specifically comprise a controller and a memory. The memory is used for storing the operation data transmitted by the transmitting component. The controller is used for monitoring the operation state of the network equipment according to the operation data stored in the memory. When the network equipment has the abnormality, the controller can also generate and send a control instruction to the abnormal network equipment.
Based on the proxy device and the control server with the above structures, on the basis of the embodiment shown in fig. 2b, another communication network may also be provided in the embodiment of the present invention, as shown in fig. 3. It should be noted that the proxy device and the control server in each communication network according to each embodiment of the present invention described below, and the proxy device and the control server according to each embodiment described below may have the above-described configuration.
As can be seen from the descriptions in the foregoing embodiments, for any network device that needs to be monitored in the dedicated sub-network, that is, the target network device, the control server may first obtain the operation data of the target network device and then monitor the target network device, and the obtaining of the operation data needs to use the source identifier of the operation data. The target network device may be any one of the different types of network devices mentioned in the embodiments, for example, any one of a CPE, an access network device, a core network device, and an application server. The process of the broker component collecting operational data of different types of network devices and adding a source identification to the operational data may be described below.
When the target network device is a network device (hardware network device for short) that is usually in a hardware form, such as a CPE or a network access device, the proxy device may call 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 correspond to the hardware network devices one to one, and the proxy devices may be installed in the hardware network devices in the form of software. Meanwhile, the source identifier needs to indicate which network device the running data is acquired by which agent device, and a one-to-one correspondence relationship between the agent device and the hardware network device, so that the agent device corresponding to the target network device can directly determine the first device identifier of the agent device itself as the source identifier of the running data of the target network device, and add the first device identifier to the running data.
When the target network device is a network device (software network device for short) that is usually represented in a software form, such as an application server or a core network device, a plurality of software network devices of the same type as the target network device may form a 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 clusters of network devices. 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 a data acquisition interface of the target network device in the network device cluster to acquire operation data of the target network device, and the target network device may be any network device in the network device cluster. Meanwhile, the proxy device can also call an access interface of the network device cluster to acquire a second device identifier of the target network device. Finally, the agent device may determine its own first device identifier and its own second device identifier as the source identifiers of the operation data collected from the target network device.
When a dedicated sub-network is deployed in the communication network, according to the correspondence between the proxy components and the different types of network devices described in the two cases, an 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 a source identifier to the operation data according to the above-described manner.
Alternatively, there may be at least one dedicated sub-network in the communication network, and the types of network devices included in the respective dedicated sub-networks may be the same or different. When a plurality of dedicated sub-networks are deployed in the communication network, the embodiment of the present invention may also provide the communication network shown in fig. 5 based on the types of network devices included in the embodiment shown in fig. 2b.
Based on the communication network shown in fig. 5, the target network device and the relationship between the proxy component and the network device in the embodiment shown in fig. 4 are simultaneously accepted, when the target network device is any hardware network device in any dedicated sub-network, the proxy device corresponding to the target network device may invoke the data acquisition interface of the target network device to acquire the operation data of the device, and at the same time, may also determine the network identifier of the dedicated sub-network in which the target network device is located. Finally, the agent device may determine the network identifier and the first device identifier of the agent device itself as the source identifier, and add the source identifier to the operation data of the target network device. Wherein, in the process of deploying a plurality of private networks to the mobile communication network, the network identification can be allocated. 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 may invoke the data acquisition interface of the target network device to acquire the operating data of the software network device, and may invoke 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 identity of the private sub-network in which the target network device is located. Finally, the agent device may determine the network identifier, the second device identifier of the target network device, and the first device identifier of the agent device itself as the source identifier, and add the source identifier to the operation data of the target network device.
When a plurality of special subnetworks are deployed in the communication network, according to the correspondence between the proxy components and 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 to 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 refer to the embodiment shown in fig. 4.
Optionally, according to respective characteristics of the state data and the configuration data in the operation data, that is, the change frequency of the state data is high, and the change frequency of the configuration data is relatively fixed and low, the agent component may further add a source identifier to different types of data at different times.
Alternatively, the proxy device may collect different types of status data of different types of network devices according to a preset period. Optionally, different types of status data of different types of network devices may be set with the same or different preset periods, and the proxy device may add a source identifier to the status data as a timing task to execute. One type of status data of a network device corresponds to a timing task.
Optionally, the agent device may further collect different types of configuration data of different types of network devices in response to configuration operations triggered by the operation and maintenance staff on the network devices. I.e. the proxy device may perform the addition of the source identification for the configuration data as a triggered task. One configuration operation by 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 for collecting the operation data of the CPE, the proxy device can collect the traffic and the number of load devices of the CPE by performing tasks 1 to m. Where the value of m is equal to the number of types of state data. The agent equipment can also acquire the IP address and DNN of the CPE, the computing resource utilization rate and the storage resource utilization rate of the CPE and the like through at least the 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 dedicated sub-network, and the operation data of the network devices may be stored in the control server in the common sub-network, specifically, in the database deployed by the control server.
The operation data can be stored in the database in a sub-table manner, that is, the control server can store the same operation data of the same type of network equipment in the same data table of the database according to the source identifier of the operation data. Wherein, the source identifier of the operation data is used to indicate which network device is deployed in which special sub-network and the operation data is collected by which agent device. The agent device may respond to the acquisition of the operation data, add to the acquired operation data, and send the operation data with the source identifier to the control server.
By means of the data table into which the operating data have been written, the control server can monitor the private sub-network for abnormalities in the respective network devices. And since the monitoring process of the control server to any network device in the dedicated sub-network, i.e. 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 a target device to be monitored from a locally stored device connection relationship list. And inquiring the operating data of the target equipment from the data table according to the source identifier, and monitoring the operating state of the target equipment according to an inquiring result. The device connection relation list reflects communication connection relations between the proxy devices and the network devices in the private sub-network. If the network devices in the private sub-network include a CPE, a network access device, a core network device, and an 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 can be seen from the description in the foregoing embodiments, the configuration data and status data of different types of network devices each include different categories, the sub-table storage of the operation data may be more specifically: the control server may store any type of status data of the same type of network device in the first data table, and store any type of configuration data of the same type of network device in the second data table.
And considering the characteristics of the state data and the configuration data, that is, the change frequency of the state data is high, the configuration data is relatively fixed, and the change frequency is low, so different types of data can be stored in corresponding data tables in different ways. Optionally, the control server may write the received first latest data as incremental data into a first data table in which the first history data is recorded; the control server may also be arranged to overwrite the second history data already recorded in the second data table with the second latest data received. The first history data and the first latest data are any type of data in status data of the same type of network device, such as traffic of the CPE. The second history data and the second latest data are any type of configuration data of the same type of network device, such as PHY layer parameters of the network access device.
Therefore, the control server stores the operation data in the sub-table according to the source identification, so that the isolation storage of different types of operation 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 does not affect the data in other data tables, 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 dedicated sub-networks are deployed in the communication network, the base control server may still monitor any network device in any dedicated sub-network in the manner described above in the embodiments shown in fig. 2a to fig. 3. In this case, optionally, for the storage of the operation data, the same kind of operation data of the same type of network devices deployed in different dedicated 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 specifically be a 5G mobile communication network, and in this case, the operation and maintenance process of the control server on the network device in the private sub-network of the 5G mobile communication network may be illustrated as follows:
it is assumed that a dedicated subnetwork in the 5G mobile communication network is deployed in an industrial park, and the dedicated subnetwork can provide voice service for mobile terminal devices in the park, automatic driving service for vehicles in the park, and control service for a manipulator on an industrial production line.
The network devices to be operated and maintained in the special sub-network may include CPE devices using various services, specifically, mobile terminal devices such as a mobile phone, a laptop, and a tablet computer using voice services, a robot arm using control services, and vehicle-mounted terminal devices installed in a vehicle using automated driving services. These devices may be considered as CPEs, that is, hardware network devices, which are the same as those described in the embodiments shown in fig. 1a and 1b, and are not described herein again. The network devices in the simultaneous private sub-network may further include a base station, a core network device in the 5GC, and an application server providing the above-described various services, and the like. The CPE normally uses the relevant service by accessing the base station. The base station may be a hardware network device, and the core network device and the application server may be a software network device. And optionally, different services may use different application servers or one application server may be common.
Any of the hardware network devices in the private sub-network may have a proxy device corresponding thereto, which may be installed in the hardware network device in the form of software. The network device cluster to which any software network device in the private sub-network belongs may have a proxy device corresponding thereto, and the proxy device may also be installed in the same hardware device as the network device cluster in the form of software.
At this time, each agent device corresponding to different network devices may collect operation data of each corresponding network device by performing different types of tasks and add a source identifier to the collected data, the operation may specifically include configuration data and status data of the network device, and the operation data with the source identifier may be sent to the control server in the common subnetwork. The process of collecting the operation data and adding the source identifier by the proxy device may refer to the description in the related embodiments, and is not described herein again.
After receiving all the operation data, the control server can store the operation data sublist in the database, and when the operation state of a certain network device in the special sub-network needs to be monitored, the control server finds the operation data of the network device in the special sub-network in the database through the source identifier, and then analyzes the operation data to determine whether the network device is abnormal. And if the network equipment is abnormal, generating and sending a corresponding control instruction to the abnormal network equipment. Finally, the abnormal network device can restore itself to normal by executing the control instruction. For example, the control instruction may control a network device to restart, or may control the network device to modify its own configuration data. For the specific storage process of the operation data and the process of monitoring the network device by the control server, reference may be made to the description in the foregoing related embodiments, which is not described herein again.
