Method and system for performing charging on network resource, and related device

A method for performing charging on a network resource, comprising:

• receiving, by a network slice management function device from a network slice charging function device, a subscription request message that comprises an identifier of a network slice instance, wherein the subscription request is used to request information for charging on the network slice instance corresponding to the identifier;
• obtaining, by the network slice management function device based on the subscription request message, data corresponding to a network slice performance indicator of the network slice instance, wherein the network slice performance indicator describes a network performance of the network slice instance;
• and
• sending, by the network slice management function device to the network slice charging function device, a subscription notification message that comprises the data corresponding to the network slice performance indicator.

A network slice charging function device, comprising:

• at least one processor and a memory, wherein the memory is configured to store a program, and wherein the program, when executed by the at least one processor, causes the network slice charging function device to carry out a method comprising:
• sending, to a network slice management function device, a subscription request message comprises an identifier of a network slice instance, wherein the subscription request message is used to request information for charging on the network slice instance corresponding to the identifier;
• receiving, from the network slice management function device, a subscription notification message that comprises data corresponding to a network slice performance indicator of the network slice instance, wherein the network slice performance indicator describes a network performance of the network slice instance;
• and
• performing charging on the network slice instance based on the data corresponding to the network slice performance indicator.

A network slice management function device, comprising:

• at least one processor and a memory, wherein the memory is configured to store a program, and wherein the program, when executed by the at least one processor, causes the network slice management function device to carry out a method comprising:
• receiving, from a network slice charging function device, a subscription request message that comprises an identifier of a network slice instance, wherein the subscription request is used to request information for charging on the network slice instance corresponding to the identifier;
• obtaining, based on the subscription request message, data corresponding to a network slice performance indicator of the network slice instance, wherein the network slice performance indicator describes a network performance of the network slice instance;
• and
• sending, to the network slice charging function device, a subscription notification message that comprises the data corresponding to the network slice performance indicator.

A system for performing charging on a network resource, comprising:

• a network slice management function device;
• and
• a network slice charging function device,
• wherein the network slice charging function device comprises at least one first processor and a first memory, wherein the first memory is configured to store a first program, and wherein the first program, when executed by the at least one first processor, causes the network slice charging function device to carry out the operations of:
• sending, to a network slice management function device, a subscription request message that comprises an identifier of a network slice instance, wherein the subscription request message is used to request information for charging on the network slice instance corresponding to the identifier;
• receiving, from the network slice management function device, a subscription notification message that comprises data corresponding to a network slice performance indicator of the network slice instance, wherein the network slice performance indicator describes a network performance of the network slice instance;
• and
• performing charging on the network slice instance based on the data corresponding to the network slice performance indicator;
• and
• wherein the network slice management function device comprises at least one second processor and a second memory, wherein the second memory is configured to store a program, and wherein the second program, when executed by the at least one second processor, causes the network slice management function device to carry out operations of:
• receiving the subscription request message from the network slice charging function device;
• obtaining, based on the subscription request message, the data corresponding to a network slice performance indicator of the network slice instance;
• and
• sending the subscription notification message to the network slice charging function device.
