Data processing method and apparatus, and system

A system comprising:

• a data analytics device configured to receive first data of a terminal from an access device in an access network;
• and
• a user plane function device configured to send second data of the terminal to the data analytics device,
• wherein the first data comprises first association information,
• wherein the first association information comprises a first identifier that is associated with an interface between the access device and the user plane function device,
• wherein the second data comprises the first association information, and
• wherein the data analytics device is further configured to associate the first data with the second data based on the first association information.

A method comprising:

• receiving, by a data analytics device through a network management device, first data of a terminal from an access device in an access network, wherein the first data comprises first association information, and wherein the first association information comprises a first identifier associated with an interface between the access device and a user plane function device;
• receiving, by the data analytics device, second data of the terminal from the user plane function device, wherein the second data comprises the first association information;
• and
• associating, by the data analytics device, the first data with the second data based on the first association information.

An apparatus comprising:

• a memory configured to store instructions;
• and
• at least one processor coupled to the memory and configured to execute the instructions to cause the apparatus to:
• receive first data of a terminal from an access device in an access network, wherein the first data comprises first association information, and wherein the first association information comprises a first identifier associated with an interface between the access device and a user plane function device;
• receive second data of the terminal from the user plane function device, wherein the second data comprises the first association information;
• and
• associate the first data with the second data based on the first association information.
