Network analysis method, function entity, and storage medium

A network analysis method, performed by a second function entity or a third function entity, comprising:

• obtaining analysis information of a target network, wherein the analysis information of the target network comprising at least one of the followings:
• analysis information of a first network, or analysis information of a second network;
• the first network is a Home Public Land Mobile Network (HPLMN), and the second network is a Visited Public Land Mobile Network (VPLMN);
• or, the first network is a VPLMN, and the second network is an HPLMN;
• sending the analysis information of the target network to a first function entity, wherein the analysis information of the target network is used by the first function entity to perform management of a Protocol Data Unit (PDU) session in a roaming scenario.

A function entity, wherein the function entity is a first function entity, comprising:

• a memory, a transceiver, and a processor, wherein
• the memory is configured to store a computer program;
• the transceiver is configured to receive and send data under the control of the processor;
• the processor is configured to read the computer program in the memory and perform the following operations:
• obtaining analysis information of the target network, wherein the analysis information of the target network comprises at least one of the followings:
• analysis information of a first network, or analysis information of a second network;
• wherein the first network is a Home Public Land Mobile Network (HPLMN), and the second network is a Visited Public Land Mobile Network (VPLMN);
• or, the first network is a VPLMN, and the second network is an HPLMN;
• performing, based on the analysis information of the target network, management of a Protocol Data Unit (PDU) session in a roaming scenario.
