[0037] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0038] The cell handover method in this application embodiment can be applied to vehicle-mounted terminals. A vehicle-mounted terminal refers to an electronic device installed in a vehicle, used to receive and transmit wireless signals. It enables the vehicle to communicate and exchange data via a wireless network, thereby realizing the vehicle's intelligence and automation capabilities. The introduction of vehicle-mounted terminals has brought revolutionary changes to vehicle communication systems, making vehicles more intelligent and automated, improving traffic efficiency and safety, reducing costs, and enhancing user experience.

[0039] Reference Figure 1 The diagram shows a flowchart of a cell handover method according to an embodiment of this application.

[0040] like Figure 1 As shown, the cell handover method may include the following steps:

[0041] Step 101: Obtain the candidate cell corresponding to the service scenario where the vehicle terminal is located, the quality parameters of the serving cell registered by the vehicle terminal, and the quality parameters of the neighboring cells corresponding to the serving cell.

[0042] The vehicle terminal can realize a variety of business scenarios, including but not limited to autonomous driving business scenarios, multimedia business scenarios, parking photography business scenarios, parking dormancy business scenarios, and so on.

[0043] Autonomous driving scenarios refer to vehicles that can control their own movement without direct driver intervention. Autonomous driving systems perceive the surrounding environment and traffic conditions, automatically making driving decisions such as acceleration, deceleration, and lane changes. Autonomous driving scenarios are low-latency services, requiring networks with even lower latency and rapid response capabilities.

[0044] Multimedia service scenarios refer to the playback of multimedia data such as video and audio. Multimedia service scenarios involve high download speeds, requiring the network to provide higher download speeds.

[0045] Parking photography involves taking photos and recording videos of the vehicle's surroundings after parking, and then uploading these images and videos to the corresponding devices. Parking photography is a high-upload-speed service, requiring a network capable of providing high upload speeds.

[0046] Parking hibernation scenarios refer to remote control functions of a vehicle, such as opening and closing doors and turning on lights, while the vehicle is parked and in hibernation mode. Parking hibernation scenarios are highly stable services, requiring networks with higher stability to reliably respond to remote control requests.

[0047] In this embodiment of the application, by obtaining the quality parameters of the candidate cells corresponding to the service scenario where the vehicle terminal is located, the quality parameters of the serving cell registered by the vehicle terminal, and the quality parameters of the neighboring cells corresponding to the serving cell, and analyzing this information, a more suitable cell can be selected for the vehicle terminal.

[0048] After the vehicle terminal is powered on, when connecting to the network, the network side will allocate a serving cell and the corresponding neighboring cells to the vehicle terminal based on the 3GPP guidelines. The relevant information of the serving cell and the relevant information of the neighboring cells will be returned to the vehicle terminal. The vehicle terminal will then initiate registration with the serving cell based on the relevant information of the serving cell, thereby registering with the serving cell.

[0049] In this embodiment, the vehicle-mounted terminal can obtain the serving cell it has registered based on the relevant information of the serving cell returned by the network side. The vehicle-mounted terminal can measure the quality of the registered serving cell to obtain its quality parameters. The quality parameters of the serving cell can be the average of multiple measurement results. The specific process for measuring the quality parameters of the serving cell can be handled based on practical experience, and will not be discussed in detail in this embodiment.

[0050] For example, the quality parameters of the registered serving cell may include, but are not limited to, at least one of the following: network quality parameters, signal quality parameters, etc. Network quality parameters may include, but are not limited to, at least one of the following: uplink packet loss rate, downlink packet loss rate, uplink retransmission rate, downlink retransmission rate, etc. Signal quality parameters may include, but are not limited to, at least one of the following: SNR (Signal-to-Noise Ratio), RSRP (Reference Signal Received Power), etc.

[0051] In this embodiment, the vehicle terminal can obtain the neighboring cells corresponding to its registered serving cell based on the relevant information of the neighboring cells corresponding to the serving cell returned by the network side. The vehicle terminal can measure the quality of the neighboring cells corresponding to the registered serving cell to obtain the quality parameters of the neighboring cells. The quality parameters of the neighboring cells can be the average of multiple measurement results. The specific process of measuring the quality parameters of the neighboring cells can be handled based on practical experience, and will not be discussed in detail in this embodiment.

[0052] For example, the quality parameters of neighboring cells corresponding to the registered serving cell may include, but are not limited to, signal quality parameters. Signal quality parameters may include, but are not limited to, at least one of the following: SNR, RSRP, etc.

[0053] When a user selects different services on the in-vehicle infotainment system, the system will enter different service scenarios accordingly. For example, if a user selects to play a video on the in-vehicle infotainment system, they will enter the multimedia service scenario; if a user selects autonomous driving on the in-vehicle infotainment system, they will enter the autonomous driving service scenario, and so on.

[0054] In this embodiment, a database corresponding to each service scenario can be set up to store candidate cells for that service scenario. Initially, the databases for each service scenario are empty. During the use of a vehicle terminal in a certain service scenario, candidate cells corresponding to that service scenario are obtained and stored in the database corresponding to that service scenario. Here, a candidate cell refers to a cell that can meet the service quality requirements of that service scenario.

[0055] In one optional implementation, after the vehicle-mounted terminal registers with any serving cell and enters any service scenario, it can record the duration of its stay in that serving cell within that service scenario and obtain the quality parameters of that serving cell during that stay. If the duration of the vehicle-mounted terminal's stay in that serving cell within that service scenario exceeds a target duration, and the quality parameters of that serving cell during that stay meet a fourth condition, then the serving cell can be considered to meet the service quality requirements of that service scenario, and therefore, it is added as a candidate cell for that service scenario. This method simplifies the processing by simply judging the dwell time and quality parameters.

[0056] It should be noted that, since this is to determine whether a cell meets the service quality requirements of the business scenario, the quality parameters of the serving cell during the stay in that serving cell can include network quality parameters. Network quality parameters can include, but are not limited to, at least one of the following: uplink packet loss rate, downlink packet loss rate, uplink retransmission rate, downlink retransmission rate, etc.

[0057] The specific value of the target duration can be set according to actual needs, and this embodiment does not impose any restrictions on it.

[0058] The fourth condition may include the fact that the network quality parameters of the serving cell are less than a preset network quality parameter threshold during the period the user stays in the serving cell. Specifically, the fourth condition may include at least one of the following: the uplink packet loss rate of the serving cell is less than a preset uplink packet loss rate threshold during the period the user stays in the serving cell; the downlink packet loss rate of the serving cell is less than a preset downlink packet loss rate threshold during the period the user stays in the serving cell; the uplink retransmission rate of the serving cell is less than a preset uplink retransmission rate threshold during the period the user stays in the serving cell; and the downlink retransmission rate of the serving cell is less than a preset downlink retransmission rate threshold during the period the user stays in the serving cell. The specific values ​​of each of the above thresholds can be set according to actual needs, and this embodiment does not limit this. For example, the uplink packet loss rate threshold can be set to 20%, the downlink packet loss rate threshold to 20%, the uplink retransmission rate threshold to 20%, the downlink retransmission rate threshold to 20%, and so on.

[0059] In this embodiment of the application, the vehicle terminal can obtain the business scenario it is in and obtain the candidate cell corresponding to the business scenario from the database corresponding to the business scenario.

[0060] In one optional implementation, the vehicle terminal can monitor in real time or periodically whether the service scenario it is in has changed. After the service scenario of the vehicle terminal changes, it can obtain the candidate cell corresponding to the service scenario of the vehicle terminal, the quality parameters of the serving cell registered by the vehicle terminal, and the quality parameters of the neighboring cells corresponding to the serving cell.

[0061] In one optional implementation, the vehicle terminal can monitor whether the cell it has registered has changed in real time or periodically. After the cell registered by the vehicle terminal changes, it can obtain the candidate cell corresponding to the service scenario in which the vehicle terminal is located, the quality parameters of the serving cell registered by the vehicle terminal, and the quality parameters of the neighboring cells corresponding to the serving cell.

[0062] In one optional implementation, the vehicle-mounted terminal can acquire, at preset time intervals, the candidate cell corresponding to the service scenario in which the vehicle-mounted terminal is located, the quality parameters of the serving cell registered by the vehicle-mounted terminal, and the quality parameters of the neighboring cells corresponding to the serving cell. The specific value of the preset time interval can be set according to actual needs, and this embodiment does not impose any restrictions on it.

[0063] Step 102: Based on the quality parameters of the candidate cell, the serving cell, and the neighboring cells, determine whether the handover conditions are met.

[0064] In this embodiment of the application, by analyzing the quality parameters of the candidate cell, the serving cell, and the neighboring cells, it can be determined whether the handover conditions are met.

[0065] In one optional implementation, the process of determining whether the handover conditions are met based on the quality parameters of the candidate cell, the serving cell, and the neighboring cells may include: determining whether a first condition, a second condition, and a third condition are met based on the quality parameters of the candidate cell, the serving cell, and the neighboring cells; determining that the handover conditions are met when all three conditions are met; and stopping the determination and determining that the handover conditions are not met when any one of the three conditions is not met.

[0066] The first condition is that the quality parameters of the serving cell do not meet the network quality requirements of the service scenario. When the quality parameters of the serving cell do not meet the network quality requirements of the service scenario, it means that the serving cell cannot adequately support the services executed in the service scenario.

[0067] Specifically, the quality parameters of the serving cell may include, but are not limited to, at least one of the following: network quality parameters and signal quality parameters. Correspondingly, the network quality requirements of the service scenario may include, at least one of the following: the network quality parameters of the serving cell are less than a preset network quality parameter threshold, and the signal quality parameters of the serving cell are greater than a preset signal quality parameter threshold.

[0068] Specifically, the network quality requirements for the service scenario may include at least one of the following: the uplink packet loss rate of the serving cell is less than a preset uplink packet loss rate threshold; the downlink packet loss rate of the serving cell is less than a preset downlink packet loss rate threshold; the uplink retransmission rate of the serving cell is less than a preset uplink retransmission rate threshold; the downlink retransmission rate of the serving cell is less than a preset downlink retransmission rate threshold; the RSRP of the serving cell is greater than a preset RSRP threshold; and the SNR of the serving cell is greater than a preset SNR threshold. The specific values ​​of each of the above thresholds can be set according to actual needs, and this embodiment does not impose any restrictions on this. For example, the uplink packet loss rate threshold can be set to 20%, the downlink packet loss rate threshold to 20%, the uplink retransmission rate threshold to 20%, the downlink retransmission rate threshold to 20%, the RSRP threshold to -110dB, the SNR threshold to 5dB, and so on.

[0069] The second condition is that there exists at least one first neighboring cell, which is a neighboring cell belonging to the candidate cell.

[0070] The third condition is that there exists a cell among the first neighboring cells with higher quality parameters than the serving cell. Specifically, higher quality parameters for the first neighboring cell mean that the signal quality parameters of the first neighboring cell are higher than those of the serving cell. For example, the RSRP of the first neighboring cell is higher than that of the serving cell, or the SNR of the first neighboring cell is higher than that of the serving cell.

[0071] Step 103: When the handover conditions are met, select a target cell from the neighboring cells and hand over to the target cell.

[0072] When it is determined that the handover conditions are met, a target cell is selected from the neighboring cells, and registration is initiated with the target cell, thereby handing over to the target cell.

[0073] In the process of determining whether the handover conditions are met, if it is determined that there is only one first neighboring cell with a quality parameter higher than that of the serving cell, then that first neighboring cell with a quality parameter higher than that of the serving cell is selected as the target cell; if it is determined that there are multiple first neighboring cells with a quality parameter higher than that of the serving cell, then the first neighboring cell with the highest quality parameter among those first neighboring cells with a quality parameter higher than that of the serving cell is selected as the target cell. Specifically, the first neighboring cell with the highest RSRP and / or SNR can be selected as the target cell.

[0074] In this embodiment, by analyzing the quality parameters of the candidate cells corresponding to the service scenario of the vehicle terminal, the serving cell registered by the vehicle terminal, and the quality parameters of the neighboring cells corresponding to the serving cell, when it is determined that the handover conditions are met, the vehicle terminal can be switched to a target cell that better meets the network quality requirements of the service scenario, thereby improving the accuracy of the registered cell.

[0075] Reference Figure 2 The diagram shows a flowchart of another cell handover method according to an embodiment of this application.

[0076] like Figure 2 As shown, the cell handover method may include: powering on the vehicle terminal; initiating a service scenario determination process to determine the current service scenario, which is divided into four types: autonomous driving service scenario, multimedia service scenario, parking photography service scenario, and parking hibernation service scenario; determining whether the handover conditions are met for the current service scenario; if the handover conditions are met, switching to the target cell; after detecting a change in the current service scenario or a change in the registered serving cell, returning to the service scenario determination process; if the handover conditions are not met, returning to the service scenario determination process after a preset time interval. For the specific processing steps, please refer to the relevant description above; this embodiment will not repeat them here.

[0080] The judgment module 302 is used to determine whether the handover conditions are met based on the quality parameters of the candidate cell, the serving cell, and the neighboring cell.

[0081] The handover module 303 is used to select a target cell from the neighboring cells and hand over to the target cell when the judgment module determines that the handover conditions are met.

[0082] Optionally, the judgment module 302 is specifically used to determine whether the first condition, the second condition, and the third condition are met based on the quality parameters of the candidate cell, the serving cell, and the neighboring cells; when the first condition, the second condition, and the third condition are all met, it is determined that the handover condition is met; wherein, the first condition is that the quality parameters of the serving cell do not meet the network quality requirements of the service scenario; the second condition is that there is at least one first neighboring cell, which is a neighboring cell belonging to the candidate cell; the third condition is that there is a cell among the first neighboring cells with a quality parameter higher than that of the serving cell.

[0085] Optionally, the acquisition module 301 is specifically used to acquire, after the service scenario of the vehicle terminal changes, the candidate cell corresponding to the service scenario of the vehicle terminal, the quality parameters of the serving cell registered by the vehicle terminal, and the quality parameters of the neighboring cells corresponding to the serving cell.

[0088] Optionally, the business scenario includes one of the following: autonomous driving business scenario, multimedia business scenario, parking photography business scenario, and parking hibernation business scenario.

[0089] In this embodiment, by analyzing the quality parameters of the candidate cells corresponding to the service scenario of the vehicle terminal, the serving cell registered by the vehicle terminal, and the quality parameters of the neighboring cells corresponding to the serving cell, when it is determined that the handover conditions are met, the vehicle terminal can be switched to a target cell that better meets the network quality requirements of the service scenario, thereby improving the accuracy of the registered cell.
