DETAILED DESCRIPTION

In order to make the technical problems, technical solutions and advantages to be solved by the present disclosure clearer, a detailed description will be given below with reference to the accompanying drawings and specific embodiments.

As shown in FIG1 , an embodiment of the present disclosure provides an information distribution method, which is performed by a first network element. The method includes:

Step 101: Obtain or receive first information, where the first information includes at least one of the following: user ID information, a Quality of Service (QoS) profile, the number of user IDs associated with a terminal ID, the number of concurrently active user IDs associated with a terminal ID, and an indication of being behind a UE or RG (5G-RG for short). The user ID information includes: identifiers of different users, applications, or devices associated with a terminal or a gateway, and/or names of different users, applications, or devices associated with a terminal or a gateway, and/or a list of identifiers of different users, applications, or devices associated with a terminal or a gateway.

Optionally, QoS profile can also be called QoS contract, QoS configuration file, or QoS view, or QoS information, etc., without specific limitation here.

Step 102: Send the first information to the terminal.

Optionally, the terminal identifier can be a user permanent identifier (SUbscription Permanent Identifier, SUPI); or, the terminal identifier can also be a generic public subscription identifier (Generic Public Subscription Identifier, GPSI).

In one implementation, the “number of simultaneously active user identifiers per SUPI” is the number of simultaneously active user identifiers per SUPI, which can also be understood as the number of simultaneously active user identifiers per SUPI.

As an optional embodiment, step 101 includes:

Sending a first request message to the second network element, where the first request message carries an identifier of the terminal;

Obtain or receive a first response message sent by the second network element, where the first response message carries the first information.

In one implementation, the first network element is a session management function network element, such as a session management function (SMF) network element or other network elements with session management functions, and the second network element is an authentication, authorization and accounting server, such as an authentication, authorization and accounting (AAA) server, or other servers with authentication, authorization and accounting functions.

Accordingly, in the case where the second network element is an authentication, authorization and accounting server,

The first request message is an authentication or authorization request message;

The first response message is an authentication or authorization response message.

Correspondingly, step 102 includes: sending the first information to the terminal through a third network element.

Optionally, the third network element is an access and mobility management function network element, such as an access and mobility management function (AMF) network element, or other network elements with access and mobility management functions.

For example, in the secondary authentication and authorization process, the SMF sends an authentication or authorization request message to the AAA server, carrying the SUPI and/or GPSI. The AAA server returns an authentication or authorization response message to the SMF, carrying the first information. In the subsequent process of establishing a Protocol Data Unit (PDU) session, the SMF sends this first information to the terminal via the AMF.

In another implementation method, the first network element is a session management function network element, such as a session management function (SMF) network element or other network element with session management function, and the second network element is a unified data management function network element or a unified data storage function network element, such as a unified data management function (UDM) network element or other network element with unified data management function or a unified data storage function (UDR) network element or other network element with unified data storage function.

In another implementation, the first network element is a session management function network element, such as a session management function (SMF) network element or other network element with session management function, and the second network element is a policy control function network element, such as a policy control function (PCF) network element, or other network element with policy control function.

Correspondingly, in the case where the second network element is a unified data management function network element or a unified data storage function network element,

The first request message is an acquisition message for acquiring session management contract information;

The first response message is the session management contract information.

And/or, in the case where the second network element is a policy control function network element,

The first request message is a session management policy association modification request message;

The first response message is a session management policy association modification response message.

Accordingly, step 102 includes:

A session management container is sent to the terminal, where the session management container carries the first information.

For example, in the PDU session establishment process, the SMF sends an acquisition message to the UDM or UDR to obtain the session management contract information, carrying the SUPI or GPSI. The UDM or UDR returns the session management contract information, carrying the above-mentioned first information. Alternatively, the SMF initiates a session management policy association modification (SM Policy Association Modification) process to the PCF, carrying the SUPI or GPSI; the PCF returns the above-mentioned first information. Further, the SMF returns the first information to the terminal, carried in the N1 SM container.

In summary, the embodiments of the present disclosure assign different identifiers to different users or different applications or different devices under a terminal in the secondary authentication process or PDU session process, thereby providing different differentiated services to different users or different applications or different devices under the same terminal or gateway.

As shown in FIG2 , an embodiment of the present disclosure further provides an information distribution method, which is performed by a second network element. The method includes:

Step 201: Send first information to a first network element, where the first information includes at least one of the following: user ID information, a quality of service (QoS) profile, the number of user IDs per terminal ID, the number of concurrently active user IDs per terminal ID, and an indication of being behind a UE or RG (5G-RG).

The user identification information includes: the identification of different users or different applications or different devices under a terminal or a gateway, and/or the names of different users or different applications or different devices under a terminal or a gateway, and/or a list of identifications of different users or different applications or different devices under a terminal or a gateway.

Optionally, QoS profile can also be called QoS contract, QoS configuration file, or QoS view, or QoS information, etc., without specific limitation here.

Optionally, the terminal identifier can be a user permanent identifier (SUbscription Permanent Identifier, SUPI); or, the terminal identifier can also be a generic public subscription identifier (Generic Public Subscription Identifier, GPSI).

In one implementation, the “number of simultaneously active user identifiers per SUPI” is the number of simultaneously active user identifiers per SUPI, which can also be understood as the number of simultaneously active user identifiers per SUPI.

As an optional embodiment, the method further includes:

Obtaining or receiving a first request message sent by the first network element, where the first request message carries an identifier of the terminal;

The sending the first information to the first network element includes:

A first response message is sent to the first network element, where the first response message carries the first information.

In one implementation, the first network element is a session management function network element, such as a session management function (SMF) network element or other network elements with session management functions, and the second network element is an authentication, authorization and accounting server, such as an authentication, authorization and accounting (AAA) server, or other servers with authentication, authorization and accounting functions.

Accordingly, in the case where the second network element is an authentication, authorization and accounting server,

The first request message is an authentication or authorization request message;

The first response message is an authentication or authorization response message.

For example, in the secondary authentication and authorization process, the SMF sends an authentication or authorization request message to the AAA server, carrying the SUPI and/or GPSI. The AAA server returns an authentication or authorization response message to the SMF, carrying the first information. In the subsequent process of establishing a Protocol Data Unit (PDU) session, the SMF sends this first information to the terminal via the AMF.

In another implementation method, the first network element is a session management function network element, such as a session management function (SMF) network element or other network element with session management function, and the second network element is a unified data management function network element or a unified data storage function network element, such as a unified data management function (UDM) network element or other network element with unified data management function or a unified data storage function (UDR) network element or other network element with unified data storage function.

In another implementation, the first network element is a session management function network element, such as a session management function (SMF) network element or other network element with session management function, and the second network element is a policy control function network element, such as a policy control function (PCF) network element, or other network element with policy control function.

Correspondingly, in the case where the second network element is a unified data management function network element or a unified data storage function network element,

The first request message is an acquisition message for acquiring session management contract information;
