Communication method, apparatus, and system

A communication method, comprising:

• receiving, by a data orchestration network element, a first service request message;
• determining, by the data orchestration network element, first requirement information and second requirement information based on requirement information, first data service capability information, and second data service capability information, wherein the requirement information is a service requirement that is on first data and that is determined based on a service requested by using the first service request message, the first data service capability information corresponds to a first-domain data orchestration network element, the second data service capability information corresponds to a second-domain data orchestration network element, the first requirement information is a service requirement that is on the first data and that corresponds to the first-domain data orchestration network element, and the second requirement information is a service requirement that is on the first data and that corresponds to the second-domain data orchestration network element;
• and
• sending, by the data orchestration network element, the first requirement information and the second requirement information.

A communication apparatus, comprising a processor coupled to a memory storing instructions, which when executed by the processor, cause the apparatus to perform:

• receiving first requirement information, wherein the first requirement information is a service requirement that is on first data and that corresponds to the domain data orchestration network element;
• determining, based on the first requirement information and one or more pieces of domain data service capability information, at least one domain data agent network element and operation configuration information corresponding to each of the at least one domain data agent network element, wherein the one or more pieces of domain data service capability information are in one-to-one correspondence with one or more domain data agent network elements, the at least one domain data agent network element is at least one of the one or more domain data agent network elements, the first requirement information corresponds to at least one of the one or more pieces of domain data service capability information, and the operation configuration information of any one of the at least one domain data agent network element indicates an operation performed by the any one domain data agent network element on the first data;
• and
• sending the operation configuration information.

A communication apparatus, comprising a processor coupled to a memory storing instructions, which when executed by the processor, cause the apparatus to:

• receive a first service request message;
• determine first requirement information and second requirement information based on requirement information, first data service capability information, and second data service capability information, wherein the requirement information is a service requirement that is on first data and that is determined based on a service requested by using the first service request message, the first data service capability information corresponds to a first-domain data orchestration network element, the second data service capability information corresponds to a second-domain data orchestration network element, the first requirement information is a service requirement that is on the first data and that corresponds to the first-domain data orchestration network element, and the second requirement information is a service requirement that is on the first data and that corresponds to the second-domain data orchestration network element;
• and
• send the first requirement information and the second requirement information.
