Technical Field

The present invention relates to the field of wireless communications, and in particular, to a method and apparatus for monitoring service quality, related devices, and a storage medium.

Background

Edge computing is an important feature of the fifth generation mobile communication technology (5G), and by providing data forwarding and capability calling near the user side, requirements of industry applications on data non-presence, low latency, and the like are met. As shown in fig. 1, in the edge computing architecture, the user plane function (UPF, user Plane Function) on the edge side provides a data forwarding function for the edge application (i.e., implements local data offloading), and the capability open platform (such as the edge computing platform (MEP, mobile Edge computing Platform)) provides a local capability call for the edge application (i.e., edge capability call).

Of the various capabilities that a capability open platform can provide for edge applications, quality of service Monitoring (english may be expressed as QoS Monitoring) is one of the more critical capabilities. For some delay-sensitive edge applications, the core requirement for edge computation is low delay, so dynamic monitoring of quality of service is critical for such applications. The edge application can dynamically adjust the service logic according to the service quality condition through the service quality monitoring capability of the capability opening platform.

However, in the related art, there is no effective solution for how to invoke the quality of service monitoring subscription capability at the edge side.

Detailed Description

The present application is described in further detail below with reference to the accompanying drawings and examples.

In the related art, as shown in fig. 2, when an edge application needs to subscribe to a quality of service monitoring event, an application program interface (API, application Programming Interface) provided by a network open function (NEF, network Exposure Function, which may also be referred to as a network capability open network element) needs to be called; after receiving the subscription request of the edge application, the NEF issues a relevant strategy for monitoring the service quality to the SMF through a strategy control function (PCF, policy Control Function); the SMF further issues service quality monitoring instructions to the UPF and the wireless side respectively to instruct the UPF and the wireless side to cooperate to execute the measurement corresponding to the service quality monitoring event. When a quality of service monitoring event subscribed by the edge application occurs, the UPF may send a notification directly to the edge application through the capability open platform.

The above-mentioned service quality monitoring mode has the following problems:

1) The edge application needs to call a capability opening interface (i.e. the API) provided by the hub side (also called core side) NEF to create a subscription for the quality of service monitoring event, but the UPF sends a notification to the edge application through the capability opening platform; in other words, the edge application needs to implement the quality of service monitoring through two interfaces, and the difficulty of managing the subscription of the quality of service monitoring event and establishing the association between the subscription and the notification is great.

2) Because the NEF, PCF and SMF are generally deployed centrally on the center side, the edge application can only bypass to the center side to invoke the quality of service monitoring subscription capability, but cannot invoke the quality of service monitoring subscription capability on the edge side, i.e., the delay of invoking the quality of service monitoring subscription capability by the edge application is higher.

Based on this, in various embodiments of the present application, the UPF can provide a service quality monitoring subscription capability, and through an interaction mechanism between the first functional body, the UPF, the SMF and the first network device, the edge application can implement, on the edge side, invocation of the service quality monitoring subscription capability, so that a delay of invoking, by the edge application, the service quality monitoring subscription capability can be reduced; meanwhile, the edge application can realize the service quality monitoring through only one interface of the UPF, and not only sends a subscription request through the interface, but also receives a subscription notification through the interface, so that the complexity of managing the subscription of the service quality monitoring event and establishing the association between the subscription and the notification by the edge application can be reduced.

An embodiment of the present application provides a method for monitoring service quality, which is applied to UPF, as shown in fig. 3, and includes:

step 301: receiving first information sent by a first functional body;

here, the first information is used for requesting subscription to a first quality of service monitoring event; the UPF can provide service quality monitoring subscription capability;

step 302: transmitting second information to the SMF;

here, the second information is used to trigger the SMF to send third information to the first network device; the second information characterizes the UPF to receive the first information; the third information is used for indicating the first network device to execute measurement corresponding to the first service quality monitoring event in cooperation with the UPF.

In actual use, the first network device may comprise a radio access network (RAN, radio Access Network) device, such as a base station or the like.

In practical application, the first functional body may also be called a first functional entity. The first functional body can comprise an electronic device (such as a server) with an edge application installed, and can also comprise a capability open platform; the capability open platform may include MEPs, local NEFs, and the like. It will be appreciated that edge applications may interact with the UPF directly or through the capability open platform.

In practical application, the UPF can provide a service interface for performing service quality monitoring subscription; in other words, the first functional body may locally invoke the interface provided by the UPF to send the first information.

Based on this, in an embodiment, the specific implementation of step 301 may include:

and receiving first information sent by the first functional body through a first interface of the UPF.

In practical application, the step 302 may be implemented by a subscription mechanism, that is, before the UPF sends the second information to the SMF, the SMF may subscribe to the UPF in advance to a service quality monitoring event requested (i.e., subscribed) by the UPF, so that the SMF sends the second information to the SMF after receiving the first information.

Based on this, in an embodiment, the method may further include:

Accordingly, in practical applications, the specific implementation of step 302 may include:

and transmitting the second information to the SMF based on the fifth information.

In actual application, the SMF can send the fifth information to the UPF through an N4 interface; the UPF may also send the second information to the SMF over an N4 interface.

Based on this, in an embodiment, the receiving the fifth information sent by the SMF includes:

the fifth information is received during creation or modification of the PDU session.

Specifically, in practical application, the UPF may receive signaling that is used by the SMF to create or modify a PDU session, where the signaling carries the fifth information.

In actual application, after the SMF receives the second information, a quality of service monitoring instruction facing the wireless side may be generated according to the second information, that is, the third information may be generated, and the third information may be sent to the first network device through an AMF; in other words, the second information is used to trigger the SMF to send third information to the first network device through the AMF.

In practical application, after the first network device receives the third information, the first network device may cooperate with the UPF to execute measurement corresponding to the first quality of service monitoring event.

Based on this, in an embodiment, the method may further include:

Specifically, in actual application, the UPF may determine, according to the first information, a first monitoring policy corresponding to the first quality of service monitoring event, and execute, based on the first monitoring policy, measurement corresponding to the first quality of service monitoring event in cooperation with the first network device; correspondingly, the first network device may determine a second monitoring policy corresponding to the first quality of service monitoring event according to the third information, and execute measurement corresponding to the first quality of service monitoring event in cooperation with the UPF based on the second monitoring policy. Here, the specific manner in which the UPF and the first network device each determine the monitoring policy may be set according to requirements, which is not limited in the embodiments of the present application.

In practical application, in order to reduce the complexity of managing subscriptions of the service quality monitoring event by the edge application and establishing an association between the subscriptions and the notifications, the UPF may receive a subscription request and send a subscription notification through the same interface (i.e. the first interface).

Based on this, in an embodiment, the sending fourth information to the edge application may include:

According to the scheme provided by the embodiment of the application, the UPF can provide the service quality monitoring subscription capability, and the edge application can realize the calling of the service quality monitoring subscription capability on the edge side through the interaction mechanism among the first functional body, the UPF, the SMF and the first network equipment, so that the time delay of calling the service quality monitoring subscription capability by the edge application can be reduced; meanwhile, the edge application can realize the service quality monitoring through only one interface of the UPF, and not only sends a subscription request through the interface, but also receives a subscription notification through the interface, so that the complexity of managing the subscription of the service quality monitoring event and establishing the association between the subscription and the notification by the edge application can be reduced.

The present application is described in further detail below in connection with examples of application.

In the present application embodiment, the quality of service is simply referred to as QoS; the first functional body comprises electronic equipment provided with an edge application, which is called edge application for short; the first network device is a base station.

The reason why the QoS subscription needs to be completed through the interaction among the NEF, PCF and SMF in the related art is that the QoS monitoring process needs to be mutually matched with the radio side on the core network side, so that the SMF needs to issue QoS monitoring instructions to the UPF and the radio side simultaneously to instruct the UPF to cooperatively execute the measurement corresponding to the QoS monitoring event with the radio side.

In the application embodiment, the UPF can provide the QoS monitoring subscription capability, and the SMF only needs to send the QoS monitoring command to the wireless side without receiving the QoS monitoring command sent by the SMF; the edge application directly calls a capability interface (namely the first interface) opened by the UPF to carry out QoS monitoring subscription, after the UPF receives a subscription request (namely the first information), subscription information (namely the second information) is reversely reported to the SMF through an N4 interface, and the SMF further sends a corresponding QoS monitoring control instruction (namely the third information) to the base station to instruct the base station to execute measurement corresponding to the QoS monitoring subscription in cooperation with the UPF.

In this application embodiment, as shown in fig. 6, the QoS monitoring process may specifically include the following steps:

step 601: in the process of creating or modifying the PDU session, the SMF sends a subscription (i.e. the fifth information described above) of the QoS monitoring subscription request to the UPF; step 602 is then performed;

step 602: the edge application sends a QoS monitoring subscription request (i.e., the first information described above) to the UPF; step 603 is then performed;

here, after the UPF receives the QoS monitoring subscription request, the core network monitoring policy (i.e., the first monitoring policy) may be loaded according to the QoS monitoring subscription request;

step 603: the UPF sends a QoS monitoring subscription request notice (namely the second information) to the SMF; step 604 is then performed;

step 604: the SMF sends QoS monitoring control instructions (namely the third information) to the AMF; step 605 is then executed;

step 605: the AMF sends QoS monitoring control instructions to the base station; step 606 is then performed;

here, after receiving the QoS monitoring control command, the base station may load a base station side monitoring policy (i.e., the second monitoring policy) according to the QoS monitoring control command;

step 606: the base station and UPF cooperate to measure the data transmission of the user plane; then executing step 607 when the measurement result meets the triggering condition corresponding to the QoS monitoring subscription request;

Step 607: the UPF sends QoS monitoring notifications (i.e., the fourth information described above) to the edge application.

According to the scheme provided by the embodiment of the application, unified QoS monitoring subscription and notification of the interface are realized at the edge side, namely, the interface of the edge application for sending the QoS monitoring subscription request to the UPF is consistent with the interface of the UPF for sending the QoS monitoring notification to the edge application, so that the complexity of managing the subscription of the service quality monitoring event by the edge application and establishing association between the subscription and the notification can be reduced; meanwhile, the time delay of calling the service quality monitoring subscription capability by the edge application can be reduced.
