Network resource management method, apparatus, and system

A method of network resource management, comprising:

• receiving, by a second management network element from a first management network element, a first resource request message used to request a first network resource and to carry first network resource requirement information;
• and
• determining, by the second management network element based on the first resource request message:
• second network resource requirement information for a second network resource corresponding to the first network resource requirement information, wherein the first network resource comprises a network slice, and the second network resource comprises a network element;
• and
• sending, by the second management network element, a second resource request message to a third management network element, wherein the second resource request message is used to request the second network resource, and the second resource request message carries the second network resource requirement information.

A communications system, wherein the system comprises a first management network element and a second management network element,

• wherein the first management network element comprises:
• a processor;
• and
• a memory, coupled to the processor and configured to store computer executable program code comprising an instruction, and when the processor executes the instruction, the instruction enables the first management network element to perform the following operations:
• receiving a service request message used to manage a target service and to carry target-service requirement information;
• determining, based on the service request message:
• first network resource requirement information for a first network resource corresponding to the target-service requirement information;
• and
• sending a first resource request message to the second management network element, wherein the first resource request message is used to request the first network resource, and the first resource request message carries the first network resource requirement information;
• and
• wherein the second management network element comprises:
• a processor;
• and
• a memory, coupled to the processor and configured to store computer executable program code comprising an instruction, and when the processor executes the instruction, the instruction enables the second management network element to perform the following operations:
• receiving from the first management network element, the first resource request message;
• and
• determining based on the first resource request message:
• second network resource requirement information for a second network resource corresponding to the first network resource requirement information, wherein the first network resource comprises a network slice, and the second network resource comprises a network element;
• and
• sending a second resource request message to a third management network element, wherein the second resource request message is used to request the second network resource, and the second resource request message carries the second network resource requirement information.
