Data management method and apparatus

A communication apparatus configured to implement a first management function unit, the communication apparatus comprising:

• a processor;
• and
• a memory configured to store computer readable instructions that, when executed by the processor, cause the communications apparatus to:
• determine association information, wherein
• the association information comprises instance information of a first management data function unit,
• the association information is used to configure an association relationship between the first management function unit and the first management data function unit,
• the first management data function unit is configured to store management data corresponding to the first management function unit,
• the first management function unit includes any of a network slice management function (NSMF), a network slice subnet management function (NSSMF), and a network function management function, and
• the first management data function unit includes a management data center;
• and
• send an association relationship configuration request to a management service function unit, wherein
• the association relationship configuration request carries the association information, and
• the management service function unit configures and stores, in the management service function unit, the association relationship between the first management function unit and the first management data function unit;
• send a first query request to the management service function unit, wherein
• the first query request carries the instance information of the first management function unit or instance indication information of the first management function unit,
• the first query request indicates to query the first management data function unit corresponding to the first management function unit, and
• the management service function unit determines instance information of the first management data function unit based on the association relationship, between the first management function unit and the first management data function unit, stored in the management service function unit;
• and
• receive the instance information of the first management data function unit sent by the management service function unit.

A system, comprising:

• a first server including:
• a processor, and
• a memory;
• and
• a second server including:
• a processor, and
• a memory, wherein
• the first server is configured to implement a first management function unit,
• the second server is configured to implement a management service function unit,
• the first management function unit is configured to:
• determine association information, wherein
• the association information comprises instance information of a first management data function unit,
• the association information is used to configure an association relationship between the first management function unit and the first management data function unit,
• the first management data function unit is configured to store management data corresponding to the first management function unit;
• the first management function unit includes any of a network slice management function (NSMF), a network slice subnet management function (NSSMF), and a network function management function,
• the first management data function unit includes a management data center, and
• the management service function unit includes a management service management function;
• and
• send an association relationship configuration request to the management service function unit, wherein the association relationship configuration request carries the association information;
• and
• the management service function unit is configured to:
• receive the association relationship configuration request;
• configure and store the association relationship between the first management function unit and the first management data function unit, wherein the association relationship is stored in the management service function unit;
• receive a first query request sent by the first management function unit, wherein
• the first query request carries instance information of the first management function unit or instance indication information of the first management function unit, and
• the first query request indicates to query the first management data function unit corresponding to the first management function unit;
• and
• determine, based on the first query request and the association relationship between the first management function unit and the first management data function unit stored in the management service function unit, the instance information of the first management data function unit, wherein the instance information of the first management data function unit corresponds to the instance information of the first management function unit;
• or
• determine, based on the first query request and the association relationship between the first management function unit and the first management data function unit stored in the management service function unit, the instance information of the first management data function unit, wherein the instance information of the first management data function unit corresponds to the instance indication information of the first management function unit;
• and
• send the instance information of the first management data function unit to the first management function unit.
