Abstract

The embodiment of the invention provides a management system, a management method, network equipment and a storage medium of a communication network, wherein access equipment in the system can acquire actual service quality parameters of target data flow, and the target data flow corresponds to target service. When the actual service quality parameter does not meet the reference service quality parameter corresponding to the target service, the access device can generate an abnormal notification corresponding to the target service, and report the abnormal notification to a management platform in the system by using a first communication interface of the access device. The management platform may forward this exception notification to a core network in the system via a second communication interface corresponding to the first communication interface to process the exception notification by the core network. The abnormal notification can indicate that the transmission of the data stream on the air interface side is abnormal, and the core network can timely sense and process the abnormality by means of the respective interfaces of the management platform and the access equipment, so that the situation that the data stream is accumulated at the access equipment due to the fact that the core network cannot sense the abnormality on the air interface side is improved.

In the case where there is no conflict between the embodiments, the following embodiments and features in the embodiments may be combined with each other. In addition, the sequence of steps in the method embodiments described below is only an example and is not strictly limited.

Fig. 1 is a communication network according to an embodiment of the present invention. The communication network may in particular be a private network deployed in a specific area, such as in an industrial park. As shown in fig. 1, the communication Network may include a Data Network (DN), a core Network, and a radio access Network (Radio Access Network, RAN). Meanwhile, the terminal equipment used by the user can also access the communication network to run various services, and specific content of the services can be seen from the following related description.

Alternatively, the private network may in particular be embodied as a cloud network or as a localization network.

Optionally, the Core Network may be a 5G Core Network (5G Core Network, 5 GC) based on the fifth generation mobile communication technology (5 th Generation Mobile Communication Technology, 5G for short), a 4G Core Network of the fourth generation mobile communication technology (4 th Generation Mobile Communication Technology, 4G for short), or a Core Network of a mixture of 4G and 5G. Wherein, the 5G core network and the 4G core network can have a common core network structure, and are not described in detail herein.

Alternatively, the RAN may comprise an access device. The access device may in particular be embodied as a base station. When the core network is specifically 5GC, the base station may be a 5G base station (the next Generation Node B, abbreviated as gNB).

Alternatively, the DN may include a data server providing a service, which may be a separate server or a cluster of servers. A data server may provide at least one service.

Alternatively, the service provided by the data server may be an instant messaging service, a live broadcast service, an information search service, or the like mentioned in the background art. The voice call service may be a call service provided by various instant messaging applications installed in the terminal device, or a call service provided by a mobile operator. The live video corresponding to the live service can be specifically a live video of a sports event or a game, or can be a live video for realizing remote education and remote medical treatment, and the like. In addition, the services provided by the data server may also include an autopilot service, an Extended Reality (XR) service, and so on. The XR services may specifically further include Virtual Reality (VR) services, augmented Reality (Augmented Reality, AR) services, mixed Reality (MR) services, and so on.

Optionally, the above services provided by the data server may be further classified into a guaranteed rate (Guarantee Bit Rate, GBR) type and a non-guaranteed rate (Non Guarantee Bit Rate, NGBR) type. The information search service may be NGBR type, and the other service may be GBR type.

For the terminal device and the data server, optionally, the terminal device corresponding to the voice call service, the live broadcast service, and the information search service may be a mobile terminal device installed with a corresponding application program, such as a mobile phone, a plane computer, a notebook computer, and so on. The data server for providing the service can store streaming media data such as teaching live video, event live video, medical live video and the like. The terminal device corresponding to the XR service may be a mobile terminal device with application programs such as VR, AR, MR, etc., or may be a wireless, wearable VR device, AR device, MR device, etc. The XR video may be stored in a data server providing this service. The terminal device corresponding to the autopilot service may be a vehicle-mounted terminal device. The data server providing the service can store various vehicle state data collected and reported by the vehicle-mounted terminal equipment, and can also generate control instructions according to the respective vehicle state data so as to control the vehicle to realize automatic driving by utilizing the control instructions.

Based on the communication network shown in fig. 1, in the process of running the target service, the terminal device and the data server providing the target service can both generate a target data flow (QoS flow), and when the target data flow specifically generates a downlink data flow for the data server, the target data flow can be transmitted from the data server to the 5GC and then transmitted to the RAN, and after receiving the target data flow, the access device in the RAN can finally forward the target data flow to the terminal device by using the allocated air interface resource, so that the user can normally use the target service. Alternatively, the target service running on the terminal device may be at least one of the various services mentioned above.

For simplicity of the following description, transmission of the target data stream represented as a downlink data stream between the terminal device and the access device may be referred to as air-side transmission, and transmission between the access device and the core network may be referred to as core network-side transmission.

In order to ensure the service quality of the target service, each device involved in the transmission process of the target data stream represented by the downlink data stream on the air interface side and the core network side can control the transmission of the data stream according to the reference service quality parameter corresponding to the target service. The details of the reference quality of service parameters may be found in the description of the embodiments described below. In practice, when the transmission of the target data stream represented as the downlink data stream on the air interface side is abnormal, the target data stream acquired by the core network cannot be forwarded normally by the access device, and finally the target data stream is accumulated at the access device and finally discarded by the access device, at this time, network packet loss occurs.

In order to improve the problem of network packet loss of the downlink data stream, the management system of the communication network provided by the following embodiments of the present invention may be used. Fig. 2a is a schematic structural diagram of a management system of a communication network according to an embodiment of the present invention. As shown in fig. 2a, the management system of the communication network may comprise a management platform, a communication network and terminal devices accessing the communication network. The communication network is specifically a private network, and the terminal device accesses the private network. And the private network may in turn comprise a core network and an access device.

It should be noted that, the target data stream in the embodiment shown in fig. 2a is a downstream data stream generated by the data server. The working procedure of the management system provided in this embodiment can be described as follows:

in the process of operating the target service by the terminal device, the data server providing the target service can generate a target data stream corresponding to the target service, and the target data stream can be sequentially transmitted on the core network side and the air inlet side so as to finally reach the terminal device.

The access device may also acquire, in real time, an actual quality of service parameter of the target data stream while the target data stream is transmitted on the air interface side, where the actual quality of service parameter indicates an actual transmission state of the target data stream in the current network state. The access device may then compare whether the actual quality of service parameter meets a reference quality of service parameter corresponding to the target service. Wherein the reference qos parameter is a transmission state reached by the target data flow when the qos of the target service is satisfied.

If the actual qos parameter meets the reference qos parameter, which indicates that the transmission of the data stream on the air interface side is normal and the qos of the target service can be guaranteed, the access device may continue to control the transmission of the target data stream on the air interface side according to the reference qos parameter.

If the actual quality of service parameter does not meet the reference quality of service parameter, the access device may generate an exception notification corresponding to the target data stream, and send the exception notification to the management platform by using the first communication interface of the access device. The exception notification may include identity information of the terminal device, such as AMF UE NGAP ID. An access and mobility management (Access and Mobility Management Function, abbreviated as AMF) network element in the core network is configured to distinguish between terminal devices using the AMF UE NGAP ID. Then, the management platform may receive the abnormality notification by using a second communication interface corresponding to the first communication interface, and further forward the abnormality notification to the core network, even if the core network senses an abnormality on the air interface side. Finally, the core network may process the anomaly notification to improve the accumulation of data flows at the access device due to air-side transmission anomalies. The process flow of the core network for the exception notification may be described in the embodiments shown in fig. 4a to fig. 4c below.

The above-described operation of the management system can also be understood in connection with the signaling diagram shown in fig. 2 b.

Optionally, the actual qos parameter and the reference qos parameter of the same service may contain the same index, and may include, for example, allocation reservation priority (Allocation and Retention Priority, ARP for short), guaranteed stream bit rate (Guaranteed Flow Bit Rate, GFBR for short), maximum stream bit rate (Maximum Flow Bit Rate, MFBR for short), aggregate maximum bit rate (AggregateMaximum Bit Rates, AMBR for short), and maximum packet loss rate (Maximum Packet Loss Rate). Meanwhile, when the core network is specifically a 5G core network, the quality of service parameter may further include a 5G quality of service Identifier (5G QoS Identifier, abbreviated as 5 QI).

Alternatively, the access device may generate an exception notification when any of the above parameters does not meet the reference quality of service parameters. In practice GFBR is one of the most often unsatisfied parameters.

The AMBR in the quality of service parameter may specifically further include Session-AMBR and UE-AMBR, and the meanings of both may be understood in conjunction with the following description.

In practice, the transmission of data streams between a terminal device and a DN depends on the session connection between the two and on the different types of transmission channels associated with the session connection. Alternatively, the session connection may specifically be a protocol data unit (Protocol Data Unit, PDU) based session connection (PDU session). The session connection may be created by a control plane network element in the core network after registration of the terminal device. Optionally, there may be at least one session connection between the terminal device and the DN.

In particular, one session connection may be associated with at least one transmission channel of a first type between the access device and the core network, and one session connection may also be associated with at least one transmission channel of a second type between the access device and the terminal device. Any one of the first-type transmission channels is used for transmitting data streams corresponding to at least one service respectively; any of the second class of transmission channels is also used for transmitting data streams corresponding to each of the at least one service. Alternatively, the first type of transmission channel may be a wired transmission channel, such as a GTP (General Packet Radio ServiceTunnelingProtocol) tunnel. The second type of transmission channel may be a wireless transmission channel, such as a data radio bearer (Data Radio Bearer, DRB) channel.

The first type of transmission channel can be used to transmit the target data stream from the core network to the access network, i.e. the transmission of the target data stream on the core network side is realized. Similarly, the second type of transmission channel can also be used to transmit the target data stream from the access device to the terminal device, i.e. the transmission of the target data stream on the air interface side is achieved.

Based on the above description of Session connection and different kinds of transmission channels, the meaning of Session-AMBR may be: the sum of transmission rates of respective corresponding data streams of at least one NGBR-type service in any type of transmission channel associated with a session connection between the terminal device and the DN. The meaning of the UE-AMBR may be: the sum of the transmission rates of the data flows respectively corresponding to the at least one NGBR type service in any type of transmission channel associated with a session connection, which is all session connections between the terminal device and the DN.

In this embodiment, the access device may obtain an actual quality of service parameter of a target data stream, where the target data stream may be generated during the operation of the target service by the terminal device. When the actual service quality parameter does not meet the reference service quality parameter corresponding to the target service, it indicates that the transmission of the target data stream between the access device and the terminal device is abnormal, that is, the transmission of the data stream on the air interface side is abnormal, the access device can generate an abnormal notification corresponding to the target service, and report the abnormal notification to the management platform by using the first communication interface of the access device. The management platform can receive and forward the abnormality notification to the core network by means of a second communication interface corresponding to the first communication interface, so that the core network senses the abnormality on the air interface side. Finally, the core network may handle this exception notification.

In addition, the technical effects achieved by the above embodiments can be further understood in combination with the following:

in practice, the access device may communicate with the core network by means of its own conventional interface, i.e. the N2 interface. However, since the N2 interface does not have a function of transmitting an abnormality notification, when the access device senses that an abnormality occurs in the transmission of the data stream on the air interface side, the abnormality is also not sensed by the core network, which further causes the data stream to be accumulated at the access device and eventually discarded.

In the embodiment described above, the access device may newly set the first communication interface, and the access device may report the abnormality notification to the core network using the newly added first communication interface and the second communication interface provided by the management platform. The interface is newly added for the access equipment, and meanwhile, a management platform is deployed in the network, so that the core network can timely sense transmission abnormality of the data flow on the air interface side, and the problem of network packet loss is finally improved.

Fig. 3a is a schematic structural diagram of another management system of a communication network according to an embodiment of the present invention. As shown in fig. 3a, on the basis of the system shown in fig. 2a, the management platform may specifically include a core network management platform and an access device management platform.

It should be noted that, the target data stream in the embodiment shown in fig. 3a is a downstream data stream generated by the data server.

The working procedure of the management system provided in this embodiment can be described as follows: after the access device generates the exception notification by comparing the quality of service parameters, the access device may send the exception notification to the access device management platform using its own first communication interface. The access device management platform may further forward the exception notification to the core network management platform using a second communication interface that corresponds to the first communication interface itself. The core network management platform is used for forwarding the abnormal notification to the core network by utilizing a third communication interface of the core network management platform. The core network may receive the abnormality notification by using a fourth communication interface corresponding to the third communication interface, where the core network senses that the transmission abnormality of the target data stream occurs on the air interface side.

The workflow of the system in this embodiment can also be understood in conjunction with the signaling diagram shown in fig. 3 b.

Optionally, the fourth communication interface of the core network may be added to a conventional interface and corresponds to the third communication interface of the core network management platform. Alternatively, the core network management platform and the access device management platform may be provided by different providers, respectively.

In this embodiment, the management platform is split into the access device management platform and the core network management platform, and then the exception notification may be sent to the access device management platform by using the first communication interface newly added by the access device and the second communication interface of the access device management platform. And then the abnormal notification can be sent to the core network by means of the third communication interface of the core network management platform and the newly added fourth communication interface of the core network, so that the core network senses transmission abnormality at the air interface side. The interface is newly added between the access equipment and the core network, and the deployment management platform can enable the core network to sense abnormal transmission of the data stream at the air interface side. Meanwhile, after the management platform is split, different providers can respectively provide the core network management platform and the access equipment management platform, so that the deployment difficulty of the whole communication network management system can be reduced. In addition, the details of the embodiment that are not described in detail and the technical effects that can be achieved can be referred to the related descriptions in the above embodiments, which are not described herein.

In practice, the target data stream, whether it appears as a downstream or upstream data stream, can be transmitted from the data server to the terminal device by means of different types of class transmission channels.

For the first type transmission channel, optionally, the core network may set up a first type transmission channel for transmitting a target data stream corresponding to the target service between the core network and the access device in response to a start operation of the target service triggered by the user on the terminal device.

The core network may also determine a reference quality of service parameter corresponding to the target service according to the subscription data of the terminal device and a preset policy (QoS policy) while creating the first type of transmission channel. Optionally, the core network may match the subscription data of the terminal device with a preset policy in multiple sets of parameters, and determine the matched parameters as the reference quality of service parameters corresponding to the target service. If the parameters are not matched in the plurality of groups of parameters, the default parameters can be determined as the reference service quality parameters corresponding to the target service. And then, the core network can also send the reference service quality parameter corresponding to the target service to the access equipment and the terminal equipment, and the access equipment can control the transmission of the target data stream at the core network side according to the reference service quality parameter.

For the second class transmission channel, optionally, the access device may determine configuration data of the second class transmission channel according to a reference quality of service parameter corresponding to the target service sent by the core network, and establish the second class transmission channel for transmitting the target data stream between the access device and the terminal device according to the configuration data. The terminal equipment can control the transmission of the target data stream on the air interface network side according to the reference service quality parameter corresponding to the target service.

Alternatively, in practice, for some services with smaller data traffic, such as the above-mentioned information search service, which has a smaller possibility of generating transmission anomalies on the air interface side, the anomaly notification corresponding to such services may not be reported to the core network. For services with larger data traffic, such as the live service, XR service, etc., the corresponding exception notification needs to be reported to the core network.

The core network may further determine, while determining the reference quality of service parameter corresponding to the target service, a notification message corresponding to the target service, where the notification message is used to indicate whether to allow the access device to report an abnormal notification corresponding to the target service to the management platform. The notification message may be issued to the access device together with the reference quality of service parameter corresponding to the target service, so that the access device may determine, according to the notification message, whether to report an abnormality notification to the core network when the data flow has a transmission abnormality on the air interface side.

Optionally, in practice, multiple services may be simultaneously run on the terminal device, and when the target data stream is specifically expressed as an uplink data stream corresponding to each of different services generated by the terminal device, the terminal device may determine, according to a recognition rule (QoSrule) sent by the core network, a second type transmission channel for transmitting an uplink data stream corresponding to each service, and further may control, according to a reference quality of service parameter corresponding to the service, transmission of the uplink data stream corresponding to the service in the corresponding second type transmission channel.

The core network may determine a reference quality of service parameter corresponding to any service according to subscription data and a preset policy of the terminal device, and may determine an identification rule according to the subscription data and the preset policy. The core network may send the identification rule and the reference quality of service parameter corresponding to the service to the terminal device.

As described in the above embodiments, at least one session connection may exist between the terminal device and the DN, and the DN may provide at least one service. Each session connection may also be associated with at least one first type of transmission channel and at least one second type of transmission channel. And the data streams corresponding to the at least one service can be transmitted in different first-type transmission channels and different second-type transmission channels.

Based on the above description, for a target data stream generated by the data server and represented as a downlink data stream, optionally, in a case where there is a transmission abnormality on the air interface side, the target service to which the target data stream belongs is a part of at least one service provided by the DN. For the case that at least one part of the service is abnormal in normal part, the core network processes the abnormal notification in the following manner: and deleting the first type transmission channel for transmitting the target data stream corresponding to the target service from at least one first type transmission channel associated with the session connection. And simultaneously, the access equipment also responds to the deletion of the first-type transmission channels, and deletes the second-type transmission channel for transmitting the target data stream corresponding to the target service in at least one second-type transmission channel associated with the session connection. At this time, the different kinds of transmission channels have been deleted, and the user cannot use the target service.

The above process can also be understood in connection with fig. 4a based on the management system shown in fig. 3 a.

In this embodiment, when an abnormality occurs in a part of at least one service provided by one session connection, a first type transmission channel and a second type transmission channel for transmitting a data stream corresponding to the abnormality service may be deleted. The method for deleting part of the transmission channels can ensure the normal use of other services. When the user restarts the abnormal service, the core network and the access device can reestablish the first-type transmission channel and the second-type transmission channel to provide the user with the service which has the abnormal service before.

Alternatively, in another case, the target service to which the target data stream with the transmission abnormality belongs at the air interface side may be all services in at least one service provided by the DN, and the processing procedure of the core network for the abnormality notification may be: in response to receipt of the anomaly notification, the session connection providing the at least one service is directly deleted. At this time, since the session connection has been deleted, the user cannot use the target service.

The above-described process can also be understood in connection with fig. 4b based on the management system shown in fig. 3a, but DN is not shown in fig. 4 b.

In this embodiment, when all services provided by one session connection are abnormal, the session connection directly deleted by the terminal device and DN may be deleted. And when the user restarts the abnormal service, the core network and the access device can reestablish the first-type transmission channel and the second-type transmission channel to provide the user with the service which has the abnormal service before.

Optionally, in another case, the target service to which the target data stream with the transmission abnormality exists on the air interface side may be a part or all of at least one service provided by the DN, and at this time, the processing manner of the core network for the abnormality notification may further be: and in response to the receiving of the abnormal notification, adjusting the reference service quality parameter corresponding to the target service, and respectively sending the adjustment result to the access equipment and the terminal equipment. For example, the actual GFBR of the target data stream collected by the access device may be Abps, and the reference GFBR corresponding to the target service may be bps, where a is less than B. At this time, after the anomaly notification generated by the access device is received by the core network, the core network may adjust the reference GFBR to C bps, where C is smaller than B.

The access device may then further adjust configuration data of the second type of transmission channel for transmitting the target data stream according to the adjustment result, so that the access device controls transmission of the target data stream in the reconfigured second type of transmission channel according to the adjustment result.

The above process can also be understood in connection with fig. 4c based on the management system shown in fig. 3 a.

In this embodiment, when at least one service provided by one session connection is abnormal, the core network may adjust a quality of service parameter corresponding to the abnormal service, and the user may not normally use the target service by adjusting the parameter, but the quality of service of the target service may be reduced due to adjustment of the reference quality of service parameter.

Fig. 5 is a schematic structural diagram of a management system of another communication network according to an embodiment of the present invention. As shown in fig. 5, the management system of the communication network may include a management platform, a communication network, and a terminal device accessing the communication network. The communication network is embodied as a private network, which may further include a core network and an access device.

In this embodiment, the private network may specifically be a localized network, and the managed private network may be a plurality of private networks, and the management platform may be deployed in a cloud network. At this time, the management system, that is, the management platform of the cloud end, is used to perform centralized management on the local multiple private networks.

Optionally, the management platform may specifically further include a core network management platform and an access device management platform.

In addition, the specific working process and the technical effects that can be achieved by the management system can be referred to the related descriptions in the above embodiments, and are not described herein again.

The specific working procedure of the management system provided in the above embodiments will be described below by taking a live service and an autopilot service as examples.

The 5G private network may be deployed in an industrial park where mobile terminal devices used by users may access the 5G private network via a gNB in the 5G private network, and on which live applications providing live services are installed. Meanwhile, the vehicle-mounted terminal equipment used by the user can also provide automatic driving service for the user after being accessed to the 5G private network. In the case that the mobile terminal device and the vehicle-mounted terminal device are connected to the 5G private network, the core network may establish a session connection for the mobile terminal device and the vehicle-mounted terminal device, and optionally, the live broadcast service and the automatic driving service may use one session connection.

Alternatively, the 5G private network may be a localized network, and the access device management platform and the core network management platform may be deployed in a cloud network.

The basic implementation procedure of the live service can be as follows: in response to a user triggering a start operation of the live application, the core network may create a GTP tunnel between the core network and the gNB for the live service, and the gNB may create a DRB tunnel between the gNB and the mobile terminal device for the live service. And then, the live data stream stored in the data server can be used as a downlink data stream to be finally transmitted to the mobile terminal equipment by means of a GTP tunnel and a DRB channel which are related to the session connection, and a user can watch the live video.

Similarly, the basic implementation of the autopilot service may be: the in-vehicle terminal device on the vehicle may be installed with an application program for providing an automatic driving service for collecting various status data generated during the running of the vehicle in real time. In response to a user triggering a start operation of the application program, the core network may create a GTP tunnel between the core network and the gNB for the autopilot service, and the gNB may create a DRB tunnel between the gNB and the vehicle terminal device for the autopilot service. The status data collected by the application may be transmitted as an upstream to the data server providing the autopilot service by means of the DRB channel and GTP tunnel associated with the session connection in succession. The data server can generate a control instruction for enabling the vehicle to realize automatic driving based on the received state data, the control instruction can be used as a downlink data stream to be fed back to an application program of the vehicle-mounted terminal device through a GTP tunnel and a DRB channel which are connected with the session in sequence, and the application program can control the vehicle to run according to the control instruction so as to realize automatic driving.

Alternatively, the data flows corresponding to the two services may be transmitted in GTP tunnel 1 and GTP tunnel 2 associated with the session connection respectively, and may also be transmitted in DRB channel 1 and DRB channel 2 associated with the session connection respectively.

In practice, in the process that the live data stream is transmitted in the DRB channel 1 and the control instruction is transmitted in the DRB channel 2, the gNB may further acquire the actual quality of service parameters of the live data stream and the control instruction in real time. The gNB may compare the actual quality of service parameter with the reference quality of service parameters for each of the two services.

In one case, the gNB may determine that there is an anomaly in the transmission of the live data stream on the air interface side. At this time, the gNB may generate an exception notification corresponding to the live broadcast service, where the exception notification may be transmitted to the access device management platform by using a communication interface newly added to the gNB, and further may be further transmitted to the core network management platform. Finally, the core network can receive the abnormal notification generated by the gNB by means of the newly added communication interface, namely, the transmission abnormality of the live data stream at the air interface side is perceived by the core network.

At this time, the core network may process this abnormality notification. In an optional processing manner, the core network may directly delete the GTP tunnel 1 and the DRB tunnel 1 for transmitting the live video stream, which does not affect the normal use of the autopilot service. Alternatively, the core network may adjust the reference qos parameters of the live service so that the obtained actual service parameters meet the adjusted reference qos parameters.

The above procedure can also be seen in fig. 6a and the flow shown in fig. 4a and 4c above.

In another case, the gNB may determine that the transmission of the live data stream and the control instruction at the air interface side is abnormal, at this time, the gNB may generate an anomaly notification corresponding to each of the live service and the autopilot service, where the anomaly notification may be transmitted to the access device management platform by using a communication interface newly added to the gNB, and further may be further transmitted to the core network management platform. Finally, the core network can receive the abnormal notification generated by the gNB by means of the newly added communication interface, namely, the transmission abnormality of the live data stream and the control instruction at the air interface side is perceived by the core network.

At this time, in an optional processing manner, the core network may directly delete session connection corresponding to the live service and the autopilot service. Alternatively, the core network may adjust the reference qos parameters of the live service and the autopilot service, respectively, so that the obtained actual service parameters meet the adjusted reference qos parameters.

The specific process may also be understood in conjunction with fig. 6b and fig. 4b to fig. 4c, and will not be described herein.

Optionally, the above procedure is also applicable to other services mentioned in the embodiment shown in fig. 1, and the detailed procedure is not repeated.

On the basis of the description of the overall working process of the management system in the above embodiments, the management process of the network from the perspective of the management platform can be described below.

Fig. 7 is a flowchart of a method for managing a communication network according to an embodiment of the present invention, where the method for managing a communication network according to the embodiment of the present invention may be executed by a management platform in the management system according to the embodiment shown in fig. 2 a. As shown in fig. 7, the method may include the steps of:

s101, receiving an abnormal notification corresponding to a target service sent by an access device by using a second communication interface corresponding to a first communication interface of the access device, wherein the abnormal notification is generated when an actual service quality parameter of a target data flow corresponding to the target service does not meet a reference service quality parameter corresponding to the target service, and the access device is deployed in a private network.

S102, forwarding the abnormal notification to a core network in the special network so that the core network processes the abnormal notification.

The access device and the core network in the embodiment may be deployed in a private network, and the management platform in the embodiment may be deployed in a cloud network. In this embodiment, the target data stream may be a downlink data stream generated by the data server.

In the transmission process of the target data stream corresponding to the target service on the air interface side, the access equipment can acquire the actual service quality parameter of the target data stream. The access device can determine whether to generate the abnormal notification by comparing the obtained actual service quality parameter with the reference service quality parameter corresponding to the target service. After the generation of the abnormality notification, the access device may send the abnormality notification to the management platform using its own first communication interface, and the management platform may receive the abnormality notification using its own second communication interface. The management platform can further forward the abnormal notification to the core network, so that the core network senses abnormal data stream transmission at the air interface side, and finally the core network can process the abnormal notification to improve the problem of data stream accumulation caused by abnormal transmission at the air interface side.

The generation process of the exception notification and the processing process of the core network for the exception notification may refer to the related descriptions in the foregoing embodiments, which are not repeated herein.

In addition, the details of the embodiment that are not described in detail and the technical effects that can be achieved can be referred to the related descriptions in the above embodiments, which are not described herein.

As shown in fig. 8, the method may include the steps of:

s201, using a second communication interface corresponding to the first communication interface of the access device, receiving an abnormal notification corresponding to the target service sent by the access device, wherein the abnormal notification is generated when the actual service quality parameter of the target data flow corresponding to the target service does not meet the reference service quality parameter corresponding to the target service, and the access device is deployed in the private network.

S202, forwarding the exception notification to a core network management platform in the cloud network, so that the core network management platform forwards the exception notification to a core network in the private network, and the core network processes the exception notification.

The access device and the core network in the embodiment may be deployed in a private network, and the access device management platform and the core network management platform in the embodiment may be deployed in a cloud network.

In the transmission process of the target data stream corresponding to the target service on the air interface side, the access device can compare the actual service quality parameter of the target data stream with the reference service quality parameter corresponding to the target service. If the actual quality of service parameter does not meet the reference quality of service parameter, the access device may generate an exception notification. Then, the access device may send the abnormality notification to the access device management platform using its own first communication interface, and the access device management platform may receive the abnormality notification using its own second communication interface. The access device management platform may further forward the exception notification to a core network management platform, which may send the exception notification to the core network by means of its own third communication interface. The core network may receive the abnormality notification by using its own fourth communication interface corresponding to the third communication interface, that is, sense that the data stream transmission on the air interface side is abnormal. Finally, the core network can process the anomaly notification to improve the problem of data stream accumulation caused by transmission anomalies occurring on the air interface side.

In addition to the management platform's perspective, the management process of the network may also be described from the perspective of the access device. Fig. 9 is a flowchart of a management method of another communication network according to an embodiment of the present invention. The method for managing the communication network provided by the embodiment of the invention can be executed by the access device in the management system provided by the above embodiments.

s301, acquiring actual service quality parameters of a target data stream, wherein the target data stream corresponds to a target service running on the terminal equipment.

S302, if the actual service quality parameter does not meet the reference service quality parameter corresponding to the target service, the first communication interface of the access device is utilized to send an exception notification corresponding to the target service to the management platform, so that the management platform receives the exception notification by utilizing the second communication interface corresponding to the first communication interface, and sends the exception notification to the core network in the private network, so that the core network processes the exception notification, and the management platform is deployed in the cloud network.

If the actual service quality parameter does not meet the reference service quality parameter corresponding to the target service, the access device can generate an abnormal notification, which indicates that the transmission of the target data stream on the air interface side is abnormal. The abnormal notification can be finally sent to the core network by means of the interface and the management platform, so that the core network senses the transmission abnormality of the target data stream on the air interface side, and the core network can eliminate the transmission abnormality of the target data stream by processing the abnormal notification.
