the functions of NRF mainly include: service discovery; specifically, a NF discovery request is received from the NF instance and information of the NF instance that is discovered is provided to the NF instance.

In the network architecture, a service architecture is adopted between the control plane network elements, a partial service architecture is adopted between the control plane network elements and the user plane network elements (namely UPF), and communication protocols, interaction flows and the like between the control plane network elements and the user plane network elements are not service. In order to better integrate UPF into SBA system architecture of 5G core network (5 GC), in the related art, it is desirable to enhance the capability of UPF for the purpose of UPF servitization, the enhanced capability may be represented in the following aspects:

first, avoiding duplicate data transmissions, reducing transmission paths, for example, considering whether PCF service can be directly subscribed or unsubscribed from UPF service to obtain QoS monitoring delay report (english may be expressed as QoS monitoring latency report);

Second, retrieving raw state or real-time traffic flow information from the UPF, such as network data analysis function (NWDAF, network Data Analytics Function) services may subscribe/unsubscribe to the UPF service to retrieve real-time service flow information (english may be expressed as real-time service flow information), e.g., considering the effective sampling interval of different services to facilitate data collection and analysis (english may be expressed as e.g., to facilitate data collection and analysis considering efficient sampling intervals for the different services).

A third UPF event exposure, such as a 5G internet of things solution, requires that the UPF be connected to a NEF (which may also be referred to as a local NEF) in order to expose network information to the application server.

However, since much of the data in UPF is relatively sensitive, it may involve privacy of the user and the network, and this data is also a core asset for the operator. Therefore, it is necessary to open up the information of the UPF from the viewpoint of security. Specifically, for which other NFs the data in the UPF can be opened, specific time for which NFs are opened, which information can be opened, and so on, there is preferably corresponding authorization management, for example, only opening to a specific NF, opening to a specific NF specific information, and so on, whether the UPF is allowed to directly open to the specific NF, or indirectly open to the specific NF through NFs of other control planes, and so on.

Based on this, in various embodiments of the present application, the information of the open UPF is authorized by the user plane or the information of the open UPF is authorized by the control plane.

According to the scheme provided by the embodiment of the application, the information of the UPF is authorized to be opened, so that the security of opening the UPF capability can be improved.

First, a flow of information for opening the UPF by user plane authorization will be described.

The embodiment of the application provides an information opening method, which is applied to UPF, as shown in figure 2, and comprises the following steps:

step 201: receiving a first request sent by a first function, wherein the first request is used for requesting to open first information; the first request at least comprises an identification of the first function and/or an identification of a UPF;

step 202: and opening second information to the first function.

In practical application, the first request may be referred to as a subscription request (the english expression may be subscribe request), or may be referred to as an authentication request, or may be an authorization request (the english expression may be Authorization request), or may be an authentication request, or may be an authorization subscription request, etc., which is not limited in this embodiment of the present application, so long as the function thereof is implemented.

The first request is used for requesting to open the information of the UPF; accordingly, the information opened to the first function is the information of the UPF.

Wherein the first request may further comprise at least one of:

an open mode;

the effective duration of the opening;

user and/or session related information;

network and/or network function related information.

Wherein, the opening mode comprises periodic opening and/or event triggering opening (namely opening after meeting a certain condition). When the manner of opening includes periodic opening, the first request may also include a specific period of opening. The open manner may also be referred to as open frequency, and the embodiment of the present application is not limited thereto, as long as the function thereof is realized.

The user and/or session related information, and network and/or network function related information may be referred to as information desired to be opened. Here, in actual application, the information desired to be opened may contain various information, which forms a list.

The user related information may include location information of the user, and the session related information may include specific rate, bandwidth information of a certain session, which is not limited in the embodiment of the present application.

The network related information may include load information of a network, and the network function related information may include load information of a UPF, which is not limited in the embodiment of the present application.

It will be appreciated that the first function refers to NF that needs to obtain the information of the UPF, such as AF, PCF, NWDAF, NEF, or charging function (CF, charging Function), which is not limited by the embodiment of the present application.

In practical application, the identifier of the first function may include at least one of a name of the first function (english may be expressed as name), a type of the first function (english may be expressed as type), an Internet Protocol (IP) address, a Fully Qualified Domain Name (FQDN), etc., which is not limited in the embodiment of the present application, so long as the first function can be identified.

The identification of the UPF may include at least one of an IP address, a FQDN, etc. of the UPF, which is not limited in the embodiment of the present application, so long as the UPF can be identified.

The first information and the second information may be the same, and illustratively, it is assumed that the UPF openable information includes: the method comprises the steps that a first function requests to open five types of information, namely a QoS monitoring delay report, real-time service flow information, information related to internet of things (IoT) equipment, charging information and load information of a UPF, and when the five types of information are authorized to be open, the UPF opens the five types of information to the first function;

The first information and the second information may also be different, and it is assumed that the UPF openable information includes: qoS monitoring delay report, real-time service flow information, ioT device related information, charging information, etc., and UPF load information, when the first function requests to open the five types of information and authorizes three types of information in the five types of information to be able to be opened (such as QoS monitoring delay report, real-time service flow information, ioT device related information), the UPF opens the three types of information to the first function, that is, the UPF opens the authorized three types of information to the first function; when the first function requests to open the location information (which may be understood as a type of location information) of the user in the UPF, and authorizes to open only a specific location information (which may be understood as a specific instance of a type of location information) of the requested location information, the UPF opens the specific user location information to the first function.

In practical application, the first information may include: at least one of QoS monitoring delay reports, real-time service flow information, ioT device-related information, billing information, UPF loading information, etc.; accordingly, the second information may include: qoS monitoring delay reports, real-time service flow information, ioT device related information, billing information, UPF loading information, and/or the like. The embodiment of the application does not limit the specific content of the first information and the second information.

When the UPF has authorization decision rights, the UPF judges which information in the first information is allowed to be opened by itself; accordingly, in step 202, the UPF directly opens the second information to the second function.

Wherein, the UPF may determine which information is allowed to be opened based on the first request and a local policy (i.e., a preconfigured policy, such as which information may be opened, which NF is opened with information, etc.). Here, in actual application, when determining which information is allowed to be opened, the UPF may further acquire subscription information of the user from the UDM, and determine whether to open corresponding information of the UPF to the first function based on the first request, the local policy, and the subscription information of the user.

When the UPF determines that the first function cannot be authorized to open information, the UPF may send a response to the first function, where the response may indicate that the request of the first request is failed; the response may also carry a reject cause value (i.e., no openness allowed).

When the UPF has no decision rights, the method may further include, before the UPF opens the second information to the first function in step 202:

opening second information of a UPF to the first function;

disallowing opening fourth information to the first function;

indicating that the opening is allowed.

It is understood that the second function refers to NF having authority to make decisions, such as PCF, NEF, or SMF, which is not limited by the embodiment of the present application.

In practical application, the second request may be referred to as a subscription request, or may be referred to as an authorization request, or may be an access authorization request, or may be an authorization subscription request, or may be an open authorization request, etc., which is not limited in this embodiment of the present application, so long as the function thereof is implemented.

Wherein the second request may further comprise at least one of:

an open mode;

the effective duration of the opening;

user and/or session related information;

network and/or network function related information.

The content indicated by the third information may further include that opening is not allowed, and when the third information indicates that opening is not allowed, the information sent by the second function may be disagreeable (english may be expressed as no), and the UPF may send a response to the first function, where the response may indicate that the request of the first request is failed; the response may also carry a reject cause value (i.e., no openness allowed).

In the case where the third information indicates second information of an open UPF to the first function, the information transmitted by the second function may be specific content of the second information. Specifically, the third information may include at least one of:

An open mode;

the effective duration of the opening;

user and/or session related information;

network and/or network function related information.

Wherein the user and/or session related information, and network and/or network function related information may be referred to as authorization open information. Here, in actual application, the information for opening authorization may contain various kinds of information, which form a list.

In case the third information indicates that opening fourth information to the first function is not allowed, the fourth information is associated with the first information and the second information. Illustratively, assuming that the first information includes QoS monitoring delay reports, real-time service flow information, ioT device-related information, charging information, and UPF load information, the fourth information includes charging information and UPF load information, the second information includes QoS monitoring delay reports, real-time service flow information, ioT device-related information.

In case the third information indicates that opening is allowed, the information sent by the second function may be consent (english may be expressed as yes).

In actual application, for the first request, the UPF may send a response to the first function, where the purpose of sending the response is to answer the request of the first function, and the response may indicate whether to subscribe to open information content that is successful and/or subscribed successfully, and so on. Specifically, as previously described, when the UPF cannot open information to the first function, the response may indicate that the request of the first request is failed; the response may also carry a reject cause value; when the UPF opens the second information to the first function, the response may indicate how to open the information, which aspects of the information to open, which information to open, and so on.

In an embodiment, according to the different open information, the UPF may open the second information to the first function in an event-triggered manner, or may open the second information to the first function periodically.

Step 401: receiving a third request sent by a fourth function, wherein the third request is used for requesting fifth information of an open UPF; the third request at least comprises an identification of the fourth function and/or an identification of a UPF;

step 402: and sending sixth information to the UPF, wherein the sixth information indicates that the UPF opens seventh information to the fourth function.

It is understood that the third function refers to NF having authority to make decisions, such as PCF, NEF, or SMF, which is not limited by the embodiment of the present application. Accordingly, the fourth function refers to NF, such as AF, PCF, NWDAF, NEF, CHF, etc., that needs to obtain the information of the UPF, which is not limited by the embodiment of the present application.

The third request is used for requesting to open the information of the UPF; accordingly, the information opened to the fourth function is the information of the UPF.

In practical application, the third request may be referred to as a subscription request, or may be referred to as an authorization request, or be an access authorization request, or be an authorization subscription request, or be an open authorization request, etc., which is not limited in this embodiment of the present application, so long as the function thereof is implemented.

The third request may further comprise at least one of:

An open mode;

the effective duration of the opening;

user and/or session related information;

network and/or network function related information.

The identifier of the fourth function may include at least one of a name of the fourth function (english may be expressed as name), a type of the fourth function, an IP address, a FQDN, etc., which is not limited in the embodiment of the present application, so long as the fourth function can be identified.

In actual application, the third function determines which information is allowed to be opened based on the third request and a local policy (i.e., a preconfigured policy, such as which information can be opened, which NF open information, etc.). Here, in actual application, when determining which information is allowed to be opened, the third function may further acquire subscription information of the user from the UDM, and determine whether to authorize (may also be referred to as allowing) the UPF to open corresponding information of the UPF to the fourth function based on the third request, the local policy, and the subscription information of the user.

The fifth information and the seventh information may be the same, and exemplarily, it is assumed that the UPF openable information includes: the fourth function requests to open the five types of information, and when the five types of information can be authorized to be opened, the UPF opens the five types of information to the fourth function;

The fifth information and the seventh information may also be different, and it is exemplarily assumed that the UPF openable information includes: qoS monitoring delay report, real-time service flow information, ioT device related information, charging information, etc., and UPF load information, when the fourth function requests to open the five types of information and authorizes three types of information in the five types of information to be able to be opened (such as QoS monitoring delay report, real-time service flow information, ioT device related information), the UPF opens the three types of information to the fourth function, that is, the UPF opens the authorized three types of information to the first function; when the fourth function requests to open the location information (which may be understood as a type of location information) of the user in the UPF, and authorizes to open only a specific location information (which may be understood as a specific instance of a type of location information) of the requested location information, the UPF opens the specific user location information to the fourth function.

In practical application, the fifth information may include: at least one of QoS monitoring delay reports, real-time service flow information, ioT device-related information, billing information, UPF loading information, etc.; accordingly, the seventh information may include: qoS monitoring delay reports, real-time service flow information, ioT device related information, billing information, UPF loading information, and/or the like. The embodiment of the present application is not limited to the specific contents of the fifth information and the seventh information.

In an embodiment, the sixth information may indicate one of:

opening seventh information to the fourth function;

disallowing opening eighth information to the fourth function;

indicating that the opening is allowed.

Wherein, the content indicated by the sixth information may further include disallowing opening, and when the sixth information indicates that opening is disallowed, the information sent by the third function to the UPF may be disagreeable, and the third function may send a response to the fourth function, where the response may indicate that the request of the third request is failed; the response may also carry a reject cause value (i.e., no openness allowed). In the case where the sixth information indicates that no opening is allowed, the UPF does not open information to the fourth function.

In the case where the sixth information indicates seventh information of the open UPF to the fourth function, the information transmitted by the third function may be a specific content of the seventh information.

In the case where the sixth information indicates that opening eighth information to the fourth function is not allowed, the eighth information is associated with the fifth information and seventh information. Illustratively, assuming that the fifth information includes QoS monitoring delay reports, real-time service flow information, ioT device-related information, charging information, and UPF load information, the eighth information includes charging information and UPF load information, the seventh information includes QoS monitoring delay reports, real-time service flow information, ioT device-related information.

In the case where the sixth information indicates that opening is permitted, the information transmitted by the third function may be consent.

In practical application, for the third request, the third function may send a response to the fourth function, where the purpose of sending the response is to answer the request of the fourth function, and the response may indicate whether to subscribe to open information content successfully and/or successfully subscribed to, and so on. Specifically, as previously described, when the third function does not authorize the UPF to open information to the fourth function, the request in the response may indicate that the request of the third request is a failure; the response may also carry a reject cause value; when the third function authorizes the UPF to open the seventh information to the fourth function, the response may indicate how to open the information, which aspects of the information to open, which information to open, and so on.

Wherein the operations of the third function sending a response to the fourth function and sending sixth information to the UPF are not sequentially ordered in execution.

In an embodiment, in a case of the seventh information indicating that the UPF is opened to the fourth function, the sixth information may include at least one of:

An open mode;

the effective duration of the opening;

user and/or session related information;

network and/or network function related information.

Correspondingly, the embodiment of the application also provides an information opening method which is applied to the fourth function and comprises the following steps:

Wherein, in an embodiment, the method may further comprise:

and receiving a response sent by the fourth function.

The embodiment of the application also provides an information opening method which is applied to UPF, as shown in figure 5, and comprises the following steps:

step 501: receiving sixth information sent by a third function, wherein the sixth information indicates that the UPF opens seventh information to a fourth function;

step 502: and opening seventh information to the fourth function.

And after receiving the sixth information sent by the third function, the UPF opens the seventh information to the fourth function according to the instruction of the sixth information.

In an embodiment, according to the different open information, the UPF may open seventh information to the fourth function in an event-triggered manner, or may open seventh information to the fourth function periodically.

According to the information opening method provided by the embodiment of the application, the fourth function sends a third request to the third function, wherein the third request is used for requesting to open fifth information of UPF; the third request at least comprises an identifier of the fourth function and/or an identifier of the UPF, and after the third request is received by the third function, sixth information is sent to the UPF, and the sixth information indicates that the UPF opens seventh information to the fourth function; and after the UPF receives the sixth information, opening seventh information to the fourth function. According to the scheme provided by the embodiment of the application, the control plane authorizes the information of the open UPF, so that the security of the open UPF capability can be improved.

The present application will be described in further detail with reference to examples of application.

Application example one

In this embodiment of the application, the information of the user plane is authorized through the control plane.

The application embodiment authorizes the information opening process of the user plane through the control plane, as shown in fig. 6, and comprises the following steps:

step 601: NF1 calls a first service of NF 2, and requests to open UPF information to NF 1;

here, the first service request message carries UPF identification information (such as an IP address, FQDN, etc.), and NF1 identification information (such as NF name, NF type, IP address, FQDN, etc.).

The first service request may also carry a manner of opening the UPF (such as event triggered opening and period opening; where, if the period is opened, a specific period may be carried), and an effective duration of opening, that is, how long, information that is not opened and is expected to be opened.

Among them, for information that is desired to be opened, since NF1 may request information of a UPF open session level or information of an open network element level to NF1, the following two cases are divided:

in the first case, the information of the open session level is requested, and the first service request message may carry a user related identifier, such as an ID (e.g., IP, flow ID, mobile phone number, general public user identifier (GPSI), session ID, etc. of the user), and may also carry a list of information (e.g., bandwidth of the session, user location, etc.) that is desired to be opened.

In the second case, information of the network element level is requested to be opened, and the first service request only carries an information list (such as a load of a UPF and the like) which is expected to be opened.

Step 602: after the NF2 receives the request, authorizing UPF opening information to NF1, and sending the opening request information to UPF;

here, NF2 determines whether to allow the UPF open information to NF 1; specifically, NF2 may combine the identification of NF1 and the content of the request according to the local policy, and may also combine subscription information related to the user obtained from the UDM, and combine these factors to comprehensively determine whether to authorize (may also be referred to as allow) NF1 to be opened by the information of the UPF, and which information to open.

NF2 sends a message to the UPF, i.e. NF2 sends authorization information to the UPF to indicate how the UPF is open (e.g. event-triggered open, period open, if period open, the message may carry a specific period, openable duration), who is open (open user session or network element related), and which information is open to NF 1.

NF2 may send messages directly to the UPF or may relay messages to the UPF through one or more intermediate NFs, such as SMF, NEF, etc.).

Here, when NF2 does not allow the information of the UPF to be opened to NF1, NF2 directly replies the NF1 with the first service response, carrying the reject cause value. .

When NF1 is AF and NF 2 is PCF, the PCF sends an open request message to the UPF through the SMF in step 602.

Step 603: NF 2 sends a first service response to NF 1;

here, it should be noted that the timing of the response message may be before or after step 602, that is, steps 602 and 603 are not sequentially performed. The response message indicates that the request of the first service request message was successful or failed. If it fails, then the reject cause value is carried. If successful, the response message may carry how the UPF is opened (e.g., event-triggered opening, periodic opening, if periodic opening, specific periods may be carried in the message, and the duration of the openable), who is opened (to which the user session or network element is associated), and which information is opened to NF1.

Step 604: the UPF defines a service through a Nupf_EventExposure_Notify service, and opens the information of the UPF to NF1.

Here, the open information may include one or more of QoS monitoring delay reports, real-time service flow information, ioT device-related information, billing information, UPF loading information, and the like.

Application example II

In this embodiment of the present application, the information of the user plane is authorized to be opened through the user plane.

In the application embodiment, a service operation nupf_eventExposure_ Subscribe service operation, namely a second service, is added in the UPF;

here, the purpose of adding this service operation is to have other NFs subscribe to the UPF message.

The application embodiment authorizes the information opening process of the user plane through the user plane, as shown in fig. 7, and comprises the following steps:

step 701: NF1 calls Nupf_EventExposure_ Subscribe service operation of the UPF, namely a second service, and requests to open UPF information to NF1;

here, the second service request message carries UPF identification information (such as an IP address, FQDN, etc.), and NF1 identification information (such as NF name, NF type, IP address, FQDN, etc.).

The second service request may also carry a manner of opening the UPF (such as event triggered opening and period opening; where, if the period is opened, a specific period may be carried), and an effective duration of opening, that is, how long, information that is not opened and is expected to be opened.

in the first case, the information of the open session level is requested, and the first service request message may carry a user related identifier, such as an ID (e.g., IP, flow ID, handset number, GPSI, session ID, etc. of the user), and may also carry a list of information (e.g., bandwidth of the session, user location, etc.) that is desired to be opened.

When NF1 is NWDAF and NF 2 is SMF, NWDAF sends the second service request, which is the open request message, to UPF through SMF.

Step 702: the UPF may or may not have decision rights, and when the UPF has decision rights, the UPF directly replies a response to the NF1 after receiving the request. When the UPF has no decision right, the NF 2 is requested to make a decision, after the NF 2 makes a decision, the UPF sends a decision result to the NF1;

here, NF 2 with decision authority may be SMF (UPF and SMF are directly connected, through N4 interface), or PCF (UPF goes through SMF to PCF). NF 2 judges whether to allow UPF open information to NF1; specifically, NF 2 may combine the identification of NF1 and the content of the request according to the local policy, and may also combine subscription information related to the user obtained from the UDM, and combine these factors to comprehensively determine whether to authorize (may also be referred to as allow) NF1 to be opened by the information of the UPF, and which information to open.

Step 703: the UPF sends a second service response to the NF1;

here, the response message indicates that the request of the second service request message is successful or failed. If it fails, then the reject cause value is carried. If successful, the response message may carry how the UPF is opened (e.g., event-triggered opening, periodic opening, if periodic opening, specific periods may be carried in the message, and the duration of the openable), who is opened (to which the user session or network element is associated), and which information is opened to NF 1.

Step 704: the UPF opens the UPF information to NF1 through the Nupf_EventExposure_Notify service.

From the above description, it can be seen that the scheme of the embodiment of the present application is an authorized user plane opening scheme, and by authorizing the user plane, it can be clear which NFs can be opened to data in the UPF, and which information can be opened when the data is opened, so that the security of UPF capability opening can be improved.
