For a better understanding of the embodiments of the present application, some of the terms or phrases appearing in the following description of the embodiments of the present application are explained as follows:

the edge configuration server: or as an Edge Data Network Configuration Server (Edge Data Network Configuration Server). An edge data network configuration server provides support functions required for a User Equipment (UE) to connect to an edge enabler server in an edge data network. An edge configuration server may also be called an edge service configuration server. The edge configuration server may be provided by a third party vendor. Similarly, the edge configuration server may be provided by the operator. A third party vendor herein refers to a service provider other than an operator.

The function of the edge data network configuration server is to provide edge data network configuration information to edge-enabled clients in the UE. The edge data network configuration information includes the following:

1) the UE connects to the edge data network by means of its service area information.

2) Information to establish a connection with an edge-enabled server (e.g., a URI) in an edge data network.

Edge-enabled servers: the edge-enabled server provides support functions required by the edge application to run in the edge data network.

The edge-enabled program server functions as: 1) providing configuration information for exchanging application data traffic with the edge application; and (2) provide information related to the edge application, such as availability, to the edge-enabled client.

An edge-enabled server may also be called an edge server.

Edge-enabled client: the edge-enabled client provides the support functions required to run the application client in the UE.

The edge-enabled client functions are: 1) retrieving and providing configuration information for exchanging application data traffic with the edge application; and 2) discovering available edge applications in the edge data network.

Example 1

According to an embodiment of the present application, an edge computing system is provided, as shown in fig. 1a, which illustrates an overall architecture of an edge computing, and an underlying network communication part of the edge computing may use a 3GPP network, a local area network, or other external network. And the middle platform part comprises a Mobile edge host (Mobile edge host) and a Mobile edge host management function (Mobile edge host level management). The Mobile edge host includes a Mobile edge platform (Mobile edge platform), a virtualization framework (e.g., NFVI), and a Mobile edge application (Mobile edge App) of the Mobile edge platform.

As shown in fig. 1b, which shows the architecture diagram of the mobile edge computing system after it is combined with the 5G core network. The host portion of the mobile edge computing system serves as the Data Network (DN) portion of the 5G core Network. The instantiated MEC coordinator acts as an Application Function (AF) part in 5G.

The AF may send a request to the SMF (session management Function) via PCF (policy Function) or NEF (network open Function) to affect User Plane Function (UPF) (User Plane Function) (re-) selection and session routing.

The corresponding relationships between the entities in fig. 1a and 1b and the related entities in fig. 2 are:

in FIG. 1a, Mobile edge host level management (Mobile edge host level management) represents an edge-enabled server. The Mobile edge application (Mobile edge app) represents an edge application. The edge configuration server provides a function of part of Mobile edge system level management (Mobile edge system level management).

In fig. 1b, the UE first obtains an IP address and a path to a Mobile edge host (Mobile edge host) through a registration and Packet Data Unit (PDU) session establishment procedure, and the path is provided by a session management function. Here the mobile edge host is the edge-enabled server. Then, the UE connects to the edge application on the edge-enabled server through a path provided by an Access Network (RAN) and the UPF.

In fig. 2, the user equipment may be connected to the corresponding edge-enabled server through the base station and different UPFs. For example, the UE may connect to a first edge-enabled server through UPF 1. The UE may also connect to the second edge-enabled server through UPF 2. In addition, an interface also exists between the UE and the edge configuration server. The UE may obtain configuration information for both edge-enabled servers from the edge configuration server. The edge configuration server may be connected to more edge-enabled servers. The edge configuration server may obtain configuration information of the edge-enabled server through an interface with the two edge-enabled servers. And the edge-enabled server may be maintained by configuration information.

In the related art, when modifying the quality of service parameters (i.e., quality of service management information) of an application session, the quality of service management information (e.g., priority policy) needs to be handed over to an operator for processing. For example, the edge-enabling server may send the identifier and type of the edge application and the priority parameter of the desired edge application (e.g., 5G QoS Indicator (5QI), etc.) to the PCF through the 5G core network, so that the PCF may support the SMF to establish the PDU session with the priority parameter of the desired edge application in the session establishment procedure phase. However, exposing information such as the edge application identifier, the type, and the expected priority parameter to the network element of the core network of the operator may affect the privacy of the user data, and in order to solve the above technical problem, in the embodiment of the present application, the edge-enabled server manages the QoS management information of all the edge applications, such as QoS priority ranking; and according to the requirement, the service quality parameters of the corresponding edge computing application are changed by sending a request to the NEF, namely, the edge computing platform directly modifies the service QoS parameters of the corresponding application session through a session modification request (PDU session modification), and the priority policy of the edge cloud is not given to an operator, so that the control of the edge computing platform on the application session policy is enhanced.

There is also provided, in accordance with an embodiment of the present application, a method embodiment for quality of service management, it being noted that the steps illustrated in the flowchart of the figure may be performed in a computer system, such as a set of computer-executable instructions, and that, although a logical order is illustrated in the flowchart, in some cases the steps illustrated or described may be performed in an order different than here.

In the embodiment of the present application, two schemes are mainly provided for an edge-enabled server to request an NEF to manage quality of service Management information, one is that the edge-enabled server sends a request message (for example, a session QoS modification message) to the NEF, and the other is that the edge-enabled server sends a request message (for example, a parameter update request message) to a Unified Data Management function (UDM), where the two implementation manners are slightly different in an interaction flow between entities, which is described in detail below.

Fig. 2 is a flow chart of an alternative method of quality of service management according to an embodiment of the application. As shown in fig. 2, the method comprises the steps of:

step S202, the edge application 1 sends an edge application registration request message to an edge-enabled server (edge enabler server), wherein the request message comprises an identifier of the edge application 1 and an edge application type;

specifically, the registration request message may also be called an edge application information registration request message or other name. In summary, the main function of this message is to make the edge-enabled server obtain the identification of the edge application, and the edge application type, etc. Optionally, the message may also carry information of the quality of service parameters that the edge application desires to acquire. The acquisition of this message facilitates the edge-enabled server to manage the quality of service for all edge applications. In all embodiments of the inventive arrangements, the quality of service parameter information (or quality of service parameters) may be equated with QoS profile (profile) data. The quality of service priority information (or priority information) may also be equivalent to QoS profile (profile) data.

Step S204, the edge enabling server sends an edge application registration reply message to the edge application 1, wherein the reply message comprises state information of whether the registration is successful or not;

specifically, the edge application registration reply message may also be called an edge application information registration reply message or other name. In summary, the main function of this message is to return information about whether the edge application sends and registers the edge application identifier, the edge application type, and the like to the edge-enabled server.

Step S206, the edge application 2 sends an edge application registration request message to the edge enabling server, wherein the request message comprises the identifier of the edge application 2 and the type of the edge application;

step S208, the edge enabling server sends an edge application registration reply message to the edge application 2, wherein the reply message comprises state information of whether the registration is successful or not;

step S210, the edge enabling server obtains a service quality list from PCF through NEF, the service quality list includes QoS priority information corresponding to each edge application type, the edge enabling server can also obtain the service quality list by sending a request message to the edge configuration server, and the edge enabling server performs priority ordering on all edge applications according to the service quality list;

in particular, the quality of service list may also be a quality of service data set. In summary, the edge computing enabling server may obtain the qos priority information of all types of applications or a part of types of applications by sending a request message to the PCF through the NEF. Optionally, in order to obtain the qos priority information of the partial application type, the edge-enabled server may carry an identifier of the partial application type, such as an identifier of a video and an identifier of an interactive game, in the request message sent by the edge-enabled server. The PCF only returns the service quality priority information corresponding to the application type identifier carried in the request message in the reply message. Without including quality of service priority information for all application types. Here, the QoS Priority information may refer to a 5G QoS Identifier (5G QoS Identifier,5QI), an Allocation and Retention Priority (ARP), a Guaranteed Uplink and Downlink Flow Bit Rate (GFBR) -Uplink and Downlink), a Maximum Flow Bit Rate (MFBR) -Uplink and Downlink), a Notification control message (Notification control), and a Maximum packet Loss Rate (Maximum ack low Rate-Uplink and Downlink).

Alternatively, the edge-enabled server may send a request to the UDM through the NEF to obtain the qos priority information corresponding to each type of edge application. And the UDM sends a reply message to the edge enabling server through the NEF, wherein the reply message comprises the service quality priority information corresponding to the requested edge application type. Optionally, the edge-enabled server may also obtain the qos priority information corresponding to each type of edge application in a preset manner, which is not limited in the present invention.

Step S212, the UE1 establishes a connection to the edge application 1 on the edge-enabled server through the PDU session established by the SMF, and the UE2 establishes a connection to the edge application 2 on the edge-enabled server through the PDU session established by the SMF;

step S214, the Edge enable Server (Edge Enabler Server) sends a session QoS modification request message (Nnef _ AFsessionWithQoS _ Modify _ Req) to the NEF, wherein the session QoS modification request message comprises a PDU session ID and a QoS profile, and the QoS profile comprises 5QI and ARP;

specifically, the first request message may be a session QoS modification request message (Nnef _ AFsessionWithQoS _ modification _ Req). Any one or more of a 5G quality of service Identifier (5G QoS Identifier,5QI), an Allocation and Retention Priority (ARP), an Uplink and Downlink Guaranteed stream Bit Rate (GFBR) -Uplink and Downlink), a Maximum stream Bit Rate (MFBR) -Uplink and Downlink), a Notification control message (Notification control), and a Maximum Packet Loss Rate (Maximum Packet Loss Rate-Uplink and Downlink) may be included in the QoS profile (profile) data. The QoS profile data included in the first request message may be preset on the edge-enabled server after the edge-enabled server has negotiated with the application provider in advance. The negotiated QoS profile data corresponds to the application identification of the application. Alternatively, the QoS profile data may be dynamically generated. For example, the application service provider may dynamically require the edge computing service provider to modify the QoS parameters corresponding to the application session. The modification here can increase the QoS parameters, e.g. increase the 5QI level, as well as the ARP level, increase the reserved bit rate of uplink and downlink guarantees, etc. In other words, the edge-enabled server may dynamically obtain QoS profile data and send a first request message to modify quality of service parameters of a session for the edge application in accordance with the data.

Optionally, the first request message may not include the session identification. The first request message may include an edge application identification. The SMF may determine a corresponding PDU session by the edge application identity and modify quality of service parameters of the PDU session in accordance with the quality of service parameters in the first request message.

Alternatively, the modification of the QoS parameter may be to lower the QoS parameter, such as to lower the 5QI level and the ARP level, to reduce the bit rate of the uplink and downlink guarantees, and so on.

Optionally, the first request message may further include time information for changing the quality of service parameter. The time information indicates a maximum time interval during which the PDU session can be modified with quality of service parameters. For example, the time information may be 5 minutes. The time information indicates that the qos modification of the PDU session can only last 5 minutes. The SMF may modify the quality of service of the PDU session and start timing at the same time upon receiving the request message. When the timing reaches 5 minutes, the SMF will resume the original service quality of the PDU session through signaling.

The first reply message corresponding to the first request message may be Nnef _ AFSessionWithQoS _ Modify _ Res.

Step S216, NEF authenticates the edge-enabled server.

Step S218, the NEF sends a PDU session update request to the SMF, wherein the PDU session update request comprises a PDU session ID and a QoS profile, and the QoS profile comprises 5QI and ARP;

specifically, the QoS profile (profile) data may include any one or more of a 5G quality of service Identifier (5G QoS Identifier,5QI), an Allocation and Retention Priority (ARP), an Uplink and Downlink Guaranteed stream Bit Rate (GFBR) -Uplink and Downlink), a Maximum stream Bit Rate (MFBR) -Uplink and Downlink), a Notification control message (Notification control), and a Maximum Packet Loss Rate (Maximum Packet Loss Rate-Uplink and Downlink).

Step S220, SMF carries out strategy control operation and judges whether the QoS management request of the edge enabling server can be accepted, the strategy can be that whether the application can be allowed to improve the QoS priority, whether the application reaches the maximum upper limit times of QoS management every day, and whether the edge enabler server reaches the maximum upper limit times of QoS management in the day;

specifically, if the SMF determines that the edge-enabled server cannot perform qos management according to the policy, the SMF sends a reply message (Nnef _ AFSessionWithQoS _ modification _ Res) to the edge-enabled service through the NEF, where the reply message includes information that the policy determination fails and reason information for rejecting the qos modification request. Alternatively, the above policy decision may be performed at the PCF side. After receiving the PDU session update request message sent by the NEF, the SMF sends a request message to the PCF to check the corresponding policy, where the request message may include the identifier of the edge-enabled server and the application type. Optionally, the request message may further include information about a desired quality of service parameter, an edge application identifier, and the like. After the PCF obtains the information, the PCF judges whether the service quality modification request can be carried out according to the strategy, if so, the PCF sends a reply message to the SMF, and the reply message carries confirmation information which can carry out the service quality modification. If not, the PCF carries the information that the strategy judgment fails and optionally the reason information for rejecting the service quality modification request in the reply message sent to the SMF.

Optionally, a white list or a black list may also be preset in the SMF or the PCF. The white list or black list may include an edge-enabled service identification, an edge application type, or an edge application identification. The SMF or PCF may determine whether the identifier is included in the white list according to the edge-enabled service identifier, the edge application type, or the edge application identifier carried in the received request message. If so, subsequent session quality of service modifications may be made. If not, the session quality of service modification request is denied. Similarly, the SMF or the PCF may determine whether the identifier is included in the blacklist according to the edge-enabled service identifier, the edge application type, or the edge application identifier carried in the received request message. If so, the session quality of service modification request is denied. If not, a subsequent session quality of service modification may be made.

Step S222, the SMF sends a communication N1N2message transfer message (Namf _ communication _ N1N2MessageTransfer) to an Access and Mobile Management Function (AMF), wherein the transfer message comprises a PDU session identifier, a QoSflow ID, a QoS profile and a session-aggregation Maximum Bit Rate (Aggregate Maximum Bit Rate);

step S224, AMF sends N2 conversation request message to access network base station, the request message includes PDU conversation mark, QoS flow ID, QoS profile, conversation-gathering Maximum bit rate (Aggregate Maximum BitRate);

in step S226, the base station adjusts the physical layer resources of the PDU session according to the QoS parameters (5QI, etc.).

Fig. 3 is a flow chart of another alternative method of quality of service management according to an embodiment of the application. As shown in fig. 3, the method includes the following steps:

step S302, the Edge application 1 sends an Edge application registration request message (Edge application registration request) to an Edge enabled server (Edge enabler server), wherein the Edge application registration request message comprises an identifier of the Edge application 1 and an Edge application type;

step S304, the Edge enabling server sends an Edge application registration reply message (Edge application registration response) to the Edge application 1, wherein the Edge application registration reply message comprises state information of whether the registration is successful or not;

step S306, the edge application 2 sends an edge application registration request message to the edge enabling server, wherein the request message comprises the identifier of the edge application 2 and the type of the edge application;

specifically, the registration request message may also be called an edge application information registration request message or other name. In summary, the main function of this message is to make the edge-enabled server obtain the identification of the edge application, and the edge application type, etc. Optionally, the message may also carry information of the quality of service parameters that the edge application desires to acquire. The acquisition of this message facilitates the edge-enabled server to manage the quality of service for all edge applications.

Step S308, the edge enabling server sends an edge application registration reply message to the edge application 2, wherein the reply message comprises state information of whether the registration is successful or not;

Step S310, the edge enabling server obtains a service quality list from PCF through NEF, the service quality list includes QoS priority information corresponding to each edge application type, the edge enabling server can also obtain the service quality list by sending a request message to the edge configuration server, the edge enabling server carries out priority ordering on all edge applications according to the service quality list, namely, the edge enabling server carries out ordering on QoS priority of applications of different providers (ordering the QoS priority for application with different traffic channels);

in particular, the quality of service list may also be a quality of service data set. In summary, the edge computing enabling server may obtain the qos priority information of all types of applications or a part of types of applications by sending a request message to the PCF through the NEF. Optionally, in order to obtain the qos priority information of the partial application type, the edge-enabled server may carry an identifier of the partial application type, such as an identifier of a video and an identifier of an interactive game, in the request message sent by the edge-enabled server. The PCF only returns the service quality priority information corresponding to the application type identifier carried in the request message in the reply message. Without including quality of service priority information for all application types. Here, the QoS Priority information may be any one or more of a 5G QoS Identifier (5G QoS Identifier,5QI), an Allocation and Retention Priority (ARP), a Guaranteed upstream and downstream Flow Bit Rate (GFBR) -Uplink and Downlink), a Maximum Flow Bit Rate (MFBR) -Uplink and Downlink), a Notification control message (Notification control), and a Maximum Packet Loss Rate (Maximum Packet Loss Rate-Uplink and Downlink).

Step S312, the UE1 establishes a connection to the edge application 1 on the edge-enabled server through the PDU session established by SMF, and the UE2 establishes a connection to the edge application 2 on the edge-enabled server through the PDU session established by SMF;

step S314, the edge enabling server sends a parameter updating request message to the NEF, wherein the parameter updating request message comprises a PDU session ID and a QoS profile, and the QoS profile comprises 5QI and ARP; the parameter update request message is used for requesting to modify the specific parameter information of the core network.

In step S316, the NEF sends a parameter configuration update Request message (numdm _ parameterprovisioning _ update _ Request) to the UDM, where the parameter configuration update Request message includes a PDU session ID and a QoS profile, including 5QI, and an ARP.

Step S318, the UDM sends a Data management update Request message (Nudr _ DM _ update _ Request) to a Unified Data storage function (UDR), where the Request message is used to update parameter information in the UDR;

specifically, if the UDM determines that the QoSprofile information or the QoS change information is included in the data management update request message received from the NEF, the UDM may directly send a data management Notification message (numm _ DM _ Notification) to the SMF, where the data management Notification message includes the QoS profile information or the QoS change information. Without first sending a data management update message to the UDR. Optionally, the UDM may also send the QoS profile information to the SMF through other messages, which is not limited in the present invention.

Step S320, receiving a data management update Response message (Nudr _ DM _ update _ Response) sent by the UDR, where the data management update Response message is used to enable the UDR to feed back a result of parameter information update through a reply message;

specifically, if the UDM directly sends the data management update request message to the SMF without passing through the UDR, the QoS profile information in the data management update request message may be carried by another message, and thus the data management update response message may also adopt another message name. In summary, the main function of this message is to return information on whether the modification of the edge computing application quality of service parameters was successful.

Step S322, the UDM sends a parameter configuration update response message (numdm _ parameterprovisioning _ update _ Res) to the NEF, where the parameter configuration update response message is used for feeding back a result of updating the UDM parameter information in S316;

step S324, the UDR sends a data management update notification message (nurr _ DM _ update notification) to the UDM;

it should be noted that if the UDM detects a session-level QoS modification, steps S318-S320 may be skipped

Step S326, the UDM sends a data management notification message (numm _ DM _ notification) to the SMF, where the notification message includes a PDU session ID and a QoS profile, which includes 5QI, and an ARP;

specifically, the QoS profile information may refer to any one or more of a 5G quality of service Identifier (5G QoS Identifier,5QI), an Allocation and Retention Priority (ARP), a Guaranteed upstream and downstream Flow Bit Rate (GFBR) -Uplink and Downlink), a Maximum Flow Bit Rate (MFBR) -Uplink and Downlink), a Notification control message (Notification control), and a Maximum Packet Loss Rate (Maximum Packet Loss Rate-Uplink and Downlink).

Step S328, the SMF performs policy control operation (for example, performs policy control on the enabling server corresponding to the edge-enabling server ID according to the edge-enabling server ID), and determines whether the QoS management request of the edge-enabling server is acceptable, where the policy may be whether such application is allowed to improve QoS priority, whether such application reaches the maximum upper limit number of QoS management each day, and whether the edge enabler server reaches the maximum upper limit number of QoS management on the same day (for example, the total management number of the edge-enabling server reaches the maximum upper limit number no matter what application is managed);

in particular, the quality of service list may also be a quality of service data set. In summary, the edge computing enabling server may obtain the qos priority information of all types of applications or a part of types of applications by sending a request message to the PCF through the NEF. Optionally, in order to obtain the qos priority information of the partial application type, the edge-enabled server may carry an identifier of the partial application type, such as an identifier of a video and an identifier of an interactive game, in the request message sent by the edge-enabled server. The PCF only returns the service quality priority information corresponding to the application type identifier carried in the request message in the reply message. Without including quality of service priority information for all application types. Here, the QoS Priority information may refer to any one or more of a 5G QoS Identifier (5G QoS Identifier,5QI), an Allocation and Retention Priority (ARP), an Uplink and Downlink Guaranteed stream Bit Rate (GFBR) -Uplink and Downlink), a Maximum stream Bit Rate (MFBR) -Uplink and Downlink), a Notification control message (Notification control), and a Maximum Packet Loss Rate (Maximum Packet Loss Rate-Uplink and Downlink).

Step S330, the SMF sends a communication N1N2message transfer message (Namf _ communication _ N1N2MessageTransfer) to the AMF, wherein the transfer message comprises a PDU session identifier, a QoSflow ID, a QoS profile and a session-aggregation Maximum Bit Rate (Aggregate Maximum Bit Rate);

step S332, AMF sends N2 Session Request message (N2 Session Request) to access network base station, the N2 Session Request message includes PDU Session identification, QoS flow ID, QoS profile, Session-aggregation Maximum Bit Rate (Aggregate Maximum Bit Rate);

in step S334, the base station adjusts AN-specific resource modification (AN-specific resource modification) of the PDU session according to the QoS parameter (5QI, etc.).

By adopting the scheme in the embodiment of the application, the management and control of the edge computing platform on the service quality are realized, the service quality does not need to be modified by an operator, the safety of the user privacy is enhanced, and the technical problems that the user privacy is required to be involved when the service quality of the edge application is modified and the safety is not high in the related technology are solved.

Based on the flows in the embodiments shown in fig. 2 and fig. 3, another method for quality of service management is provided in the embodiment of the present application, and fig. 4 is a flowchart of another method for quality of service management according to the embodiment of the present application. As shown in fig. 4, the method includes the following processing steps:

In an optional embodiment, the qos management information may further include, but is not limited to: the first session identifies priority information for the corresponding session, including but not limited to: when the service quality of the session is adjusted, the priority of the sequence is adjusted; when the quality of service of the session is adjusted, priority (e.g., network bandwidth, etc.) of more resources is preferentially allocated.

Step S404, the edge-enabled server receives a first response message corresponding to the first request message sent by the network openness function entity, where the first response message includes a management result of the service quality of the session.

Wherein, the first request message includes but is not limited to: 1, a session QoS modification request message, wherein the session QoS modification request message comprises a PDU session ID and a QoS profile, and the QoS profile comprises 5QI and ARP; parameter update request message parameters, the parameter update request message including a PDU session ID and a QoS profile, the QoS profile (profile) including any one or more of a 5G quality of service Identifier (5G QoS Identifier,5QI), Allocation and Retention Priority (ARP), Uplink and Downlink Guaranteed stream Bit Rate (GFBR) -Uplink and Downlink), Maximum stream Bit Rate (MFBR) -Uplink and Downlink), Notification control message (Notification control), and Maximum Packet Loss Rate (Maximum Packet Loss Rate-Uplink and Downlink).

Wherein, the second request message includes but is not limited to: a PDU session update request message, wherein the PDU session update request message comprises a PDU session ID and a QoS profile, and the QoS profile comprises 5QI and ARP.

There are various ways for the edge-enabled server to obtain the qos information, for example, the following ways may be adopted:

1) before the edge enabling server sends the first request message to the network open functional entity, the edge enabling server sends a third request message to the network open functional entity; the edge-enabled server receives a third response message corresponding to the third request message, wherein the third response message includes a quality of service list, and the quality of service list includes: and the service quality priority information corresponds to the type of the edge application, wherein the service quality priority information is the service quality priority of the session between the user equipment and the edge application on the edge enabling server.

2) The edge enabling server sends a request message to the edge configuration server; the edge enabling server receives a service quality list fed back by the edge configuration server according to the request message, wherein the service quality list comprises: and the service quality priority information is the service quality priority of the session between the user equipment and the edge application on the edge enabling server. The request message may be an existing request message between the edge-enabled server and the edge configuration server, or may be a request message configured between the edge-enabled server and the edge configuration server and dedicated to sending the qos list, and is flexibly selected according to an actual situation.

3) The edge enabling server determines a session type corresponding to the edge application; the method comprises the steps that an edge enabling server determines first target service quality information corresponding to a session type according to the session type; the edge enabling server determines the service quality information corresponding to at least one edge application type included in the first request message based on the first target service quality information.

Optionally, there are various ways for the edge-enabled server to determine the session type, such as: receiving a registration request message sent by an edge application; determining a corresponding application type according to the application identifier in the registration request message; since the application type is often related to the service or service provided by the application, for example, the type corresponding to the video playing application is video, the session type can be determined according to the application type. For another example, a session establishment request message sent by the edge application is received; determining a corresponding application type according to an application identifier in the session establishment request message; the session type is determined according to the application type.

It should be noted that the first target qos information may be used in combination with the qos management information obtained in the modes 1) and 2), that is, the qos management information in the first request message is determined based on the first target qos information and the qos management information obtained from other ways. For example, the priority of the quality of service of the edge application is determined based on the sum of the weight of the quality of service management information in the first request message and the weight of the first target quality of service information, such as: the first target qos information indicates an increase in priority, and the quality management information increases a priority based on the original priority.

The session types may further include: a vehicle navigation service session, an AR or VR scene session, etc.

4) The edge enabling server receives second target service quality information sent by the user equipment running the edge application; and the edge enabling server determines the service quality information corresponding to at least one edge application type included in the first request message based on the second target service quality information.

Optionally, there are various ways for the edge-enabled server to receive the second target quality of service information, for example: receiving a PDU session establishment request message sent by the UE, wherein the PDU session establishment request message comprises reflection QoS (reflective QoS) information. The edge-enabled server may obtain the reflection QoS information and determine target QoS profile information from the reflection QoS information. As another example, a session establishment request message sent by an edge application is received; second target quality of service information is extracted from the session establishment request message.

It should be noted that the second target qos information may be used in combination with the qos management information obtained in the modes 1) and 2), that is, the qos management information in the first request message is determined based on the second target qos information and the qos management information obtained from other ways. For example, the priority of the quality of service of the edge application is determined based on the sum of the weight of the quality of service management information in the first request message and the weight of the second target quality of service information, such as: the second target qos information indicates an increase in priority, and the quality management information increases a priority based on the original priority.

5) The edge-enabled server receives location information of a user device running an edge application; the edge-enabled server determines the area to which the position information belongs; the method comprises the steps that an edge enabling server determines the number of user equipment requesting to establish a session with the edge enabling server in an area; the edge enabling server determines third target service quality information of the user equipment according to the number of the user equipment; and the edge enabling server determines the service quality information corresponding to the at least one edge application type included in the first request message based on the third target service quality information.

Optionally, there are various ways for the edge-enabled server to obtain the location information, for example: receiving a registration request message sent by an edge application; the location information is extracted from the registration request message. As another example, a session establishment request message sent by an edge application is received; the location information is extracted from the session establishment request message. As another example, the above location information from the edge application is received directly through a dedicated message.

It should be noted that the third target qos information may be used in combination with the qos management information obtained in the modes 1) and 2), that is, the qos management information in the first request message is determined based on the third target qos information and the qos management information obtained from other ways. For example, the priority of the quality of service of the edge application is determined based on the sum of the weight of the quality of service management information in the first request message and the weight of the third target quality of service information, such as: the third target qos information indicates an increase in priority, and the quality management information increases a priority based on the original priority.

In some embodiments of the present application, after the network open function entity sends the second request message to the session management function entity, the session management function entity determines whether to accept a management request of the edge-enabled server according to the policy, where the management request is used to request to modify a quality of service parameter of a session corresponding to the first session identifier. Specifically, the method comprises the following steps:

The edge-enabled server sends a fourth response message corresponding to the fourth request message to the edge application, the response message including but not limited to: a registration reply message, the registration reply message comprising: whether the edge application registers successful state information.

In the embodiment of the application, the edge-enabled server sets the first session identifier and the qos management information corresponding to at least one edge application type in the first request message sent to the network open functional entity, so that the network open functional entity can send the second request message to the session management functional entity to request the session management functional entity to modify the qos parameter information of the session corresponding to the first session identifier, thereby implementing qos control by the edge computing platform without modifying the qos by an operator, enhancing the security of user privacy, and further solving the technical problems of low security and user privacy requirement when modifying the qos of the edge application in the related art.

a sending module 90, configured to send a first request message to the opennetwork function entity, where the first request message includes a first session identifier and qos management information corresponding to each edge application type, and the qos management information includes first qos indication information and first priority information of a session corresponding to the first session identifier, the first request message is used to enable the opennetwork function entity to send a second request message to the session management function entity, and the second request message is used to request the session management function entity to modify priority parameter information of the session corresponding to the first session identifier;

the receiving module 92 is configured to receive a first response message corresponding to a first request message sent by the network openness function entity, where the first response message includes result information of modifying a priority parameter of a session.

Example 8

Fig. 11 is a flow chart of an alternative method of quality of service management according to an embodiment of the application. As shown in fig. 11, the method comprises the steps of:

step S1102, an edge-enabled server sends an eighth request message to a session management function entity, where the eighth request message includes a first session identifier and qos management information corresponding to at least one edge application type, where the qos management information includes first qos indication information, and the eighth request message is used to request the session management function entity to modify qos parameter information of a session corresponding to the first session identifier;

specifically, the eighth request message may be an SMF PDU session Update request message (Nsmf _ PDU _ Update _ Req). The edge-enabled server may send the SMF PDU session update request message directly to the session management function SMF without going through the network open function entity NEF. The first QoS indication information may include any one or more of a 5G QoS Identifier (5G QoS Identifier,5QI), an Allocation and Retention Priority (ARP), a Guaranteed Uplink and Downlink stream Bit Rate (GFBR) -Uplink and Downlink), a Maximum stream Bit Rate (MFBR) -Uplink and Downlink), a Notification control message (Notification control), and a Maximum Packet Loss Rate (Maximum Packet Loss Rate-Uplink and Downlink). The qos indicator included in the first request message may be preset on the edge-enabled server after the edge-enabled server negotiates with the application provider in advance. The negotiated service quality indication information corresponds to the application identifier of the application. Alternatively, the service quality indication information may be dynamically generated. For example, the application service provider may dynamically require the edge computing service provider to modify the QoS parameters corresponding to the application session. The modification here can increase the QoS parameters, e.g. increase the 5QI level, as well as the ARP level, increase the reserved bit rate of uplink and downlink guarantees, etc. In other words, the edge-enabled server may dynamically obtain the quality of service indication information and send the first request message to modify the quality of service parameters of the session to which the edge application corresponds according to the data.

Alternatively, the SMF PDU session Update request message (Nsmf _ PDU _ Update _ Req) may be replaced by another message. In summary, the function of the eighth request message is to allow the edge-enabled server to send the quality of service management information directly to the SMFs. All messages supporting this function may be eighth request messages.

Step S1104, the edge-enabled server receives an eighth response message corresponding to the eighth request message sent by the session management functional entity, where the eighth response message includes a management result of the service quality of the session.

Specifically, the eighth request message may be an SMF PDU session Update reply message (Nsmf _ PDU _ Update _ Res). The main function of this message is to return information on whether the modification of the edge computing application quality of service parameters was successful. For example, when the bit indicating whether the QoS parameter update is successful in the SMF PDU session update reply message is 1, it indicates that the QoS parameter update is successful. If the bit is 0, it indicates that the update of the QoS parameter fails. Optionally, if the QoS parameter update fails, the SMF PDU session update reply message may also include update failure cause information.
