Network parameter optimization method and apparatus

A network parameter optimization apparatus, comprising:

• a sending unit, configured to send an evaluation model to a second function entity, wherein the evaluation model is used by the second function entity to determine a first network parameter adjustment action performed by a network element in a first network environment state;
• a receiving unit, configured to receive information about the first network parameter adjustment action;
• and
• a model training unit, configured to update the evaluation model based on information about the first network environment state, the information about the first network parameter adjustment action, information about a return obtained after the network element performs the first network parameter adjustment action, and information about a second network environment state after the network element performs the first network parameter adjustment action, wherein
• the sending unit is further configured to send an evaluation model obtained after update to the second function entity, wherein the evaluation model obtained after the update is used by the second function entity to determine a second network parameter adjustment action performed by the network element in the second network environment state,
• wherein the receiving unit is further configured to:
• before the model training unit updates the evaluation model, receive configuration information of a rule, wherein the rule includes at least one of the following:
• a type and/or a calculation apparatus of a network environment status, a range and a step of a network parameter adjustment action, and a type and/or a calculation apparatus of a return;
• and
• the model training unit is further configured to:
• obtain, based on the rule received by the receiving unit, network data of this type of network environment status and of this type of return from a third function entity, and determine, based on the network data, the information about the return obtained after the network element performs the first network parameter adjustment action and the information about the second network environment state.

A communications system, comprising a first function entity and a second function entity, the first function entity and the second function entity each comprise a processor and a memory, respectively, wherein

• the first function entity is configured to send an evaluation model to the second function entity;
• the second function entity is configured to:
• receive the evaluation model from the first function entity, and determine, based on the evaluation model, a first network parameter adjustment action performed by a network element in a first network environment state;
• and
• the first function entity is further configured to:
• receive information about the first network parameter adjustment action;
• update the evaluation model based on information about the first network environment state, the information about the first network parameter adjustment action, information about a return obtained after the network element performs the first network parameter adjustment action, and information about a second network environment state after the network element performs the first network parameter adjustment action;
• and
• send, to the second function entity, an evaluation model obtained after update, wherein the evaluation model obtained after the update is used by the second function entity to determine a second network parameter adjustment action performed by the network element in the second network environment state,
• wherein the first function entity is further configured to receive configuration information of a rule, wherein the rule includes at least one of the following:
• a type and/or a calculation method of a network environment status, a range and a step of a network parameter adjustment action, and a type and/or a calculation method of a return;
• obtain, based on the rule, network data of this type of network environment status and of this type of return from a third function entity;
• and
• determine, based on the network data, the information about the return obtained after the network element performs the first network parameter adjustment action and the information about the second network environment state.
