Network resource management method and communication apparatus

A communication apparatus, comprising at least one processor coupled to at least one memory storing computer instructions, which when executed by the at least one processor, cause the communication apparatus to:

• receive a first message from a second network element, wherein the first message carries an identifier of a first terminal device, and the first message is used to request to create or select a first user service node corresponding to the first terminal device;
• obtain subscription information or policy information of the first terminal device from a third network element based on the identifier of the first terminal device;
• and
• create the first user service node based on the subscription information or the policy information of the first terminal device, wherein a network capability of the first user service node matches the subscription information or the policy information of the first terminal device and the first user service node is configured to provide a network service for the first terminal device.

A non-transitory computer-readable storage medium storing instructions which when executed by at least one processor cause a first network element to:

• receive a first message from a second network element, wherein the first message carries an identifier of a first terminal device, and the first message is used to request to create or select a first user service node corresponding to the first terminal device;
• obtain subscription information or policy information of the first terminal device from a third network element based on the identifier of the first terminal device;
• and
• create the first user service node based on the subscription information or the policy information of the first terminal device, wherein a network capability of the first user service node matches the subscription information or the policy information of the first terminal device and the first user service node is configured to provide a network service for the first terminal device.
