[0125] Based on the above content and in conjunction with application scenarios, the technical solutions of this disclosure are illustrated below.

[0126] In one embodiment of this disclosure, the first network entity is a Non-RT RIC, and the network function is the intelligent control unit in the Near-RT RIC. In the following communication flow, Near-RT RIC can refer to the intelligent control unit in the Near-RT RIC. The Non-RT RIC includes rApp, OAM-related function, and A1 policy function, where rApp is equivalent to the first function described above, and the OAM-related function is equivalent to the second function described above. The relevant communication flow is as follows:

[0127] 1. rApp requests the OAM-related function in Non-RT RIC to query the scope of the wireless optimization policy. The query message carries the user identifier, which is the user's mobile phone number.

[0128] 2. The OAM-related function interacts with core network elements, associates the user's mobile phone number with the user's network identifier, and determines the cell and base station where the terminal corresponding to the user's mobile phone number is located based on the network identifier; the OAM-related function interacts with the TE&IV function (third network function), and can determine the Near-RT RIC where the terminal is located based on cell and / or base station information and the connection relationship between the cell and / or base station and the Near-RT RIC, thus serving as the target Near-RT RIC (Near-RT RIC under the action of radio optimization strategy).

[0129] 3. Based on the identification information of the target Near-RT RIC, rApp sends a request to the A1 policy function in the Non-RT RIC to create a wireless optimization policy, which carries the identification information of the target Near-RT RIC;

[0130] 4. The A1 policy function receives the wireless optimization policy sent by rApp and sends the wireless optimization policy to the target Near-RT RIC.

[0131] In another embodiment of this disclosure, the first network entity is a Non-RT RIC, and the network function is the intelligent control unit in the Near-RT RIC. In the following communication flow, Near-RT RIC can refer to the intelligent control unit in the Near-RT RIC. The Non-RT RIC includes rApp, OAM-related function, and A1 policy function, where rApp is equivalent to the first function described above, and the OAM-related function is equivalent to the second function described above. The relevant communication flow is as follows:

[0132] 1. rApp subscribes to the scope of the wireless optimization policy from the OAM-related function, and the subscription message carries the user identifier, which is the user's mobile phone number;

[0133] 2. The OAM-related function interacts with core network elements, associates the user's mobile phone number with the user's network identifier, and determines the cell and base station where the user's mobile phone number is located based on the network identifier. In some embodiments, the OAM-related function can subscribe to the location information of the corresponding terminal from the core network through the user's mobile phone number. When the cell and / or base station where the terminal is located changes, the core network will notify the OAM-related function.

[0134] 3. The OAM-related function interacts with the TE&IV function (third network function) and, based on cell and / or base station information and the connection relationship between the cell and / or base station and the Near-RT RIC, can determine the Near-RT RIC where the terminal is located, and thus use it as the target Near-RT RIC (the Near-RT RIC where the radio optimization strategy is applied).

[0135] 4. Based on the identification information of the target Near-RT RIC obtained through subscription, rApp sends a request to the A1 policy function in the Non-RT RIC to create a wireless optimization policy, which carries the identification information of the target Near-RT RIC;

[0136] 5. The A1 policy function receives the wireless optimization policy sent by rApp and sends it to the target Near-RT RIC;

[0137] 6. When the terminal's location changes due to movement, causing a change in its Near-RT RIC, the OAM-related function will notify rApp;

[0138] 7. rApp will send a new request to the A1 policy function to create a wireless optimization policy based on the latest Near-RT RIC identification information, which will carry the redefined identification information of the target Near-RT RIC.

[0139] 8. The A1 policy function sends the wireless optimization policy to the redefined target Near-RT RIC.

[0140] As can be seen from the two examples above, the technical solution provided in this disclosure, by introducing a mapping service from policy scope to network function, can determine the network function to which the wireless optimization policy applies through simple service calls, thereby supporting the accurate and effective distribution of wireless optimization policies. A universal and unified service can maintain the mapping relationship between policy scope and network function, achieving unified and efficient management. Simultaneously, a unified association method can reduce system signaling interaction overhead. Furthermore, considering changes in terminal mobility, the above can also help predict the network function to which the optimization policy may migrate in the future, achieving proactive prediction services. Through the prediction service, the migration of policies between network functions can be proactively triggered, ensuring the continuity of wireless optimization policy implementation.
