[0055] For better understanding of the embodiments of this application, the wireless network AI related to this application is described.

[0056] The application of artificial intelligence (AI) to the standardization work of mobile communications has been gradually carried out in the 3rd Generation Partnership Project (3GPP). Among them, research and standardization work have been carried out on three use cases: mobility optimization, load balancing, and network energy saving. The AI function deployment options for the three use cases are the same, including the following two methods:

[0057] Method 1: The AI training function is deployed in Operation Administration and Maintenance (OAM), and the AI inference function is deployed in the base station;

[0066]

[0067] As can be seen from Tables 1 to 3 above, the network-side data mainly includes the current service status and future service status predictions of the serving cell and neighboring cells.

[0068] This application proposes a performance optimization scheme. The terminal reports the preference of the terminal for performing the first operation or the information obtained based on the AI model-based mobility inference, so that the network-side device can perform terminal-level configuration optimization based on the preference information of the terminal to achieve UE centric performance improvement, and can solve the problem of terminal-level performance improvement that cannot be achieved by network-centric data collection and optimization.

[0069] It should be noted that UE centric data collection and optimization can reduce the probability of extremely poor user experience and improve the lower limit of the user experience level, which is called Self-Optimizing Experience (SOE).

[0070] To facilitate the understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The above related technologies can be arbitrarily combined with the technical solutions of the embodiments of the present application as optional solutions, and all of them fall within the protection scope of the embodiments of the present application. The embodiments of the present application include at least some of the following content.

[0071] Figure 2 is a schematic flowchart of a wireless communication method 200 according to an embodiment of the present application. As Figure 2 shown, the wireless communication method 200 may include at least some of the following content:

[0072] S210, the terminal sends first information to the network-side device;

[0073] wherein, the first information is used to indicate at least one of the following: the terminal's preference for performing a first operation, information obtained based on AI model-based mobility inference; wherein, the first operation includes at least one of the following: cell handover, cell redirection, connection reestablishment, cell selection, cell reselection, activation of a deactivated cell, entering the idle state, leaving the connected state, shutting down, entering the flight mode, AI model-based mobility inference;

[0074] S220, the network-side device receives the first information from the terminal.

[0075] It should be understood that Figure 2 shows the steps or operations of the wireless communication method 200, but these steps or operations are only examples. The embodiments of the present application may also perform other operations or Figure 2 variations of each operation in.

[0076] In the embodiments of the present application, the terminal sends at least one of the following to the network-side device: the terminal's preference for performing a first operation, information obtained based on AI model-based mobility inference; so that the network-side device can perform terminal-level configuration optimization based on the information reported by the terminal to achieve performance improvement centered on the terminal (UE centric).

[0077] In some embodiments, the first information may be carried by dedicated signaling. For example, the first information is carried by the UE Assistance Information, or a new dedicated signaling is introduced to carry the first information.

[0078] In some embodiments, the terminal's preference for performing the first operation further includes: related information of at least one cell.

[0079] In some embodiments, the at least one cell includes but is not limited to at least one of the following:

[0080] The cell to which the terminal expects to handover, the cell to which the terminal expects to be redirected, the cell that the terminal expects to select, the cell that the terminal expects to reselect, the cell to which the terminal expects to reconnect during connection reestablishment, the cell that the terminal expects to activate.

[0081] It can be understood that, taking the first operation as cell handover as an example, the terminal can send an indication that the terminal expects to perform handover (for example, an explicit 1-bit indication) and the cell information to which the terminal expects to handover. The terminal can also only send the information related to the cell to which the terminal expects to handover, and this information can implicitly indicate the terminal's preference for performing cell handover.

[0082] In some embodiments, the related information of the at least one cell includes but is not limited to at least one of the following:

[0083] Cell Global Identity (CGI), Physical Cell Identifier (PCI), carrier frequency information, Tracking Area Code (TAC), Tracking area Identity (TAI).

[0084] Exemplarily, the first information is associated with MRO or MLB. The first information includes the terminal's preference for performing the first operation, and the terminal's preference for performing the first operation includes the related information of at least one cell.

It can be understood that the network side can perform mobility management on the terminal based on the first information. For example, the network side can handover / redirect the terminal to its preferred cell. For another example, the network side can release the terminal and configure the information for the terminal to perform cell reselection; for some terminals (such as high-priority terminals), the network side can determine whether to preferentially balance to other cells or keep the terminal in the current cell according to the terminal's preferences.

[0085] Exemplarily, the terminal can determine its preference for performing the first operation based on implementation, for example, based on the information already available to the terminal, or the terminal can determine its preference for performing the first operation based on the related information inferred by the AI mobility model.

[0086] Exemplarily, the first information is associated with the NES. The first information includes the terminal's preference for performing a first operation, and the terminal's preference for performing the first operation includes relevant information about at least one cell. In this case, the at least one cell may include or be the cell that the terminal expects to activate, that is, it indicates to the network side the cell that the terminal expects to connect and activate. It can be understood that for some terminals (such as high-priority UEs), the network side can determine which cells to turn off / activate according to the terminal's preferences.

[0087] In some embodiments, the information obtained by mobility inference based on the AI model includes, but is not limited to, at least one of the following:

[0088] Measurement results of the serving cell, and the measurement results of the serving cell include at least one of the following: Reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), Signal to Interference plus Noise Ratio (SINR);

[0091] In some embodiments, the abnormal handover includes, but is not limited to, at least one of the following: ping-pong handover, premature handover, late handover, handover to the wrong cell.

[0092] Exemplarily, the ping-pong handover may refer to: the terminal switches back and forth between two cells.

[0093] Exemplarily, premature handover may refer to: RLF occurs shortly after handover from a source cell to a target cell, or handover fails during the process of handover from a source cell to a target cell and based on the measurement results obtained by the terminal, the source cell is still a suitable cell.

[0094] Exemplarily, late handover may refer to: RLF occurs in the source cell when the terminal has not yet performed handover and based on the measurement results obtained from the terminal, there is a cell that is a suitable cell, and the cell is a cell different from the source cell.

[0095] Exemplarily, handover to the wrong cell may refer to: RLF occurs shortly after handover from a source cell to a target cell, or handover fails during the process of handover from a source cell to a target cell, and based on the measurement results obtained from the terminal, there is a cell that is a suitable cell, and the cell is a cell different from the source cell and the target cell.

[0096] In some embodiments, the abnormal PSCell change includes but is not limited to at least one of the following: ping-pong PSCell change, premature PSCell change, late PSCell change, change to the wrong PSCell.

[0097] Exemplarily, ping-pong PSCell change may refer to: The terminal performs PSCell changes back and forth between two PSCs.

[0098] Exemplarily, premature PSCell change may refer to: SCG failure occurs shortly after a successful PSCell change from a source PSCell to a target PSCell, or PSCell replacement fails during the PSCell change, and based on the measurement results obtained from the terminal, the source PSCell is still a suitable PSCell.

[0099] Exemplarily, late PSCell change may refer to: SCG failure occurs when the terminal has not yet performed PSCell change, and based on the measurement results obtained from the terminal, there is a cell that is a suitable PSCell, and the cell is a cell different from the source PSCell.

[0100] Exemplarily, change to the wrong PSCell may refer to: SCG failure occurs shortly after a successful PSCell change from a source PSCell to a target PSCell, or failure occurs during the PSCell change, and based on the measurement results obtained from the terminal, there is a cell that is a suitable cell, and the cell is a cell different from the source PSCell and the target PSCell.

[0101] Exemplarily, the first information is associated with the information obtained by the mobility inference based on the AI model. The first information includes the information obtained by the mobility inference based on the AI model, and the information obtained by the mobility inference based on the AI model includes at least one of the following: the measurement result of the serving cell, the measurement results of at least one neighboring cell, and the inference result of the AI model. Thus, the network-side device can configure the terminal to perform operations such as handover or redirection according to the information obtained by the mobility inference based on the AI model.

[0108] In some embodiments, the terminal performs a second operation according to the second information;

[0118] Wherein, the second cause information is used to indicate the reason why the network side does not activate the cell that the terminal expects to activate.

[0119] In this embodiment, the network side may configure the time information when the terminal is not allowed to send the first information, so as to avoid the terminal sending the first information frequently. As long as it is not within the time indicated by the time information when the terminal is not allowed to send the first information, when the terminal re-sends the first information can be based on the terminal implementation.

[0120] In this embodiment, the terminal may determine the reason why the network side does not configure the terminal to perform the first operation based on the first cause information, or the terminal may determine the reason why the network side does not activate the cell that the terminal expects to activate based on the second cause information.
