[0031] The device switching method and electronic device provided in the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0032] In this article, the term "and / or" is merely a description of the relationship between related objects, indicating that there can be three relationships. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone.

[0033] The terms "first" and "second," etc., used in the specification and drawings of this application are used to distinguish different objects or to distinguish different treatments of the same object, rather than to describe a specific order of objects.

[0034] Furthermore, the terms "comprising" and "having," and any variations thereof, used in the description of this application are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the steps or units listed, but may optionally include other steps or units not listed, or may optionally include other steps or units inherent to such process, method, product, or apparatus.

[0035] It should be noted that in the embodiments of this application, the words "exemplary" or "for example" are used to indicate examples, illustrations, or explanations. Any embodiment or design scheme described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design schemes. Specifically, the use of the words "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0036] Figure 1 A schematic diagram of a scenario architecture provided for an embodiment of this application, such as Figure 1As shown, the scenario includes a terminal device 101, a serving cell 102 of the terminal device, and multiple inter-frequency neighboring cells 103. The terminal device 101, upon sensing excessive uplink interference noise in the serving cell 102, sends a first request message to the serving cell 102 to identify multiple inter-frequency neighboring cells 103. The terminal device 101 then determines which inter-frequency neighboring cells 103 have signal strengths that meet the signal quality requirements.

[0037] Serving cell 102 is the serving cell of terminal device 101. Serving cell 102 is used to determine the handover target cell from inter-frequency neighboring cells 103 that meet the signal quality requirements.

[0038] When the uplink interference of the serving cell 102 is high, the inter-frequency neighbor cell 103 provides the terminal device 101 with a switchable target cell.

[0039] Through the above description of the implementation methods, those skilled in the art will clearly understand that, for the sake of convenience and brevity, only the division of the above functional modules is used as an example. In practical applications, the above functions can be assigned to different functional modules as needed, that is, the internal structure of the network node can be divided into different functional modules to complete all or part of the functions described above. The specific working process of the system, modules, and network nodes described above can be referred to the corresponding process in the foregoing method embodiments, and will not be repeated here.

[0040] Domestic major operators generally use low-frequency bands such as 900MHz and 800MHz for their 4G and 5G networks as basic support networks. However, these frequency bands suffer from severe uplink interference in certain areas. The severe interference is generally caused by residents privately installing signal-blocking devices. Severe uplink interference noise can prevent base station cells from effectively analyzing and decoding uplink data, thus seriously affecting the communication quality of terminal devices.

[0041] Currently, the majority of solutions to these problems involve operators investigating and rectifying the interference, but this process is extremely difficult. One approach operators use to handle cells with severe uplink interference is to temporarily block the base station cell or implement strict access policies to prohibit terminal devices from using it; this leads to a significant waste of base station resources. Another approach is to eliminate co-channel interference in macro-Femtocells, reducing the probability of uplink transmission interruptions and thus improving the speed / network throughput for all users and network capacity. However, this method only avoids co-channel interference. Therefore, how to rationally switch terminal devices and ensure their communication quality is a pressing issue that needs to be addressed.

[0042] To address the problems in the prior art, embodiments of this application provide a method such as... Figure 2 The device handover method shown involves the following steps: First, the terminal device identifies at least one target inter-frequency neighbor cell, where the signal quality of the target inter-frequency neighbor cell is greater than a first threshold, indicating that the signal conditions of the target inter-frequency neighbor cell are good. Next, the terminal device determines the interference noise threshold of the at least one target inter-frequency neighbor cell. Then, the terminal device sends the interference noise threshold of the at least one target inter-frequency neighbor cell to the serving cell. The serving cell determines the target difference for each target inter-frequency neighbor cell based on the average interference noise value and the interference noise threshold of each target inter-frequency neighbor cell. The target inter-frequency neighbor cell with the largest target difference is selected as the handover target cell. A large target difference indicates that the signal quality of the target inter-frequency neighbor cell can cover the interference noise value, ensuring that the terminal device is not affected by interference noise. Therefore, the serving cell sends handover instruction information for the handover target cell to the terminal device, instructing the terminal device to initiate a handover to the handover target cell, thereby ensuring a reasonable handover for the terminal device and improving the communication quality of the terminal device.

[0043] like Figure 2 The diagram shown is a flowchart of a device switching method provided in an embodiment of this application. The device switching method provided in this embodiment can be applied to, for example... Figure 1 As shown in the schematic diagram of the scenario architecture, the device switching method provided in this application embodiment can be implemented through the following steps.

[0044] S201. The terminal device determines at least one target inter-frequency neighbor cell whose signal quality is greater than a first threshold, based on the signal quality of the inter-frequency neighbor cells of the serving cell, and the interference noise threshold of each target inter-frequency neighbor cell in the at least one target inter-frequency neighbor cell.

[0045] Among them, the serving cell is the serving cell of the terminal device.

[0046] It is worth noting that the terminal device presets a first threshold and a signal evaluation period for inter-frequency neighboring cells. The first threshold is a signal quality threshold for the inter-frequency neighboring cells. If the terminal device detects that the signal quality of the inter-frequency neighboring cells is less than the first threshold, the terminal device does not perform any action.

[0047] As one possible implementation, the above-mentioned S201 process can be as follows: when the terminal device detects that the signal quality of the inter-frequency neighboring cell is continuously greater than a first threshold during the signal evaluation period, the terminal device determines that the signal quality of the inter-frequency neighboring cell is good and can be identified as a target inter-frequency neighboring cell. There can be at least one target inter-frequency neighboring cell, or multiple target inter-frequency neighboring cells. Furthermore, the terminal device adds the signal quality of the target inter-frequency neighboring cell to a preset bias value to determine the interference noise threshold of the target inter-frequency neighboring cell.

[0048] The preset paranoia value is greater than or equal to 2dB.

[0049] For example, the terminal device determines the first threshold as -100dBm; the inter-frequency neighboring cells of the serving cell include inter-frequency neighboring cell A with a signal quality of -86dBm, inter-frequency neighboring cell B with a signal quality of -88dBm, and inter-frequency neighboring cell C with a signal quality of -101dBm.

[0050] If the signal quality of inter-frequency neighboring cell A is -86dBm, which is greater than the first threshold of -100dBm, the terminal device determines inter-frequency neighboring cell A as the target inter-frequency neighboring cell.

[0051] If the signal quality of inter-frequency neighbor B is -88dBm, which is greater than the first threshold of -100dBm, the terminal device determines inter-frequency neighbor B as the target inter-frequency neighbor.

[0052] If the signal quality of inter-frequency neighboring cell C is less than -101dBm and the first threshold is less than -100dBm, the terminal device determines that inter-frequency neighboring cell C does not belong to the target inter-frequency neighboring cell.

[0053] After the terminal device identifies inter-frequency neighboring cells A and B as target inter-frequency neighboring cells, it adds a preset offset value of -3dBm to the signal quality of inter-frequency neighboring cell A (-86dBm), determining the interference noise threshold of inter-frequency neighboring cell A to be -89dBm. Similarly, it adds a preset offset value of -3dBm to the signal quality of inter-frequency neighboring cell B (-88dBm), determining the interference noise threshold of inter-frequency neighboring cell B to be -91dBm.

[0054] S202, the terminal device sends the interference noise threshold of each target inter-frequency neighbor cell in at least one inter-frequency neighbor cell to the serving cell. Correspondingly, the serving cell receives the interference noise threshold of each target inter-frequency neighbor cell in at least one target inter-frequency neighbor cell sent by the terminal device.

[0055] Among them, at least one target inter-frequency neighbor cell is an inter-frequency neighbor cell whose signal quality is greater than a first threshold among the inter-frequency neighbor cells of the serving cell.

[0056] Referring to the example in S201, the terminal device sends the interference noise threshold of inter-frequency neighboring cell A (-89dBm) and the interference noise threshold of inter-frequency neighboring cell B (-91dBm) to the serving cell.

[0057] S203. The serving cell determines the average interference noise value of each target inter-frequency neighboring cell.

[0058] In one possible implementation, the terminal device sends each target inter-frequency neighbor cell and the interference noise threshold of each target inter-frequency neighbor cell to the serving cell, and requests the serving cell to obtain the average interference noise value of each target inter-frequency neighbor cell.

[0059] Referring to the example in S202, the serving cell receives the interference noise threshold of inter-frequency neighbor A as -89dBm and the interference noise threshold of inter-frequency neighbor B as -91dBm, and determines the average interference noise value of inter-frequency neighbor A as -105dBm and the average interference noise value of inter-frequency neighbor B as -108dBm.

[0060] S204. The serving cell determines at least one handover target cell among the target inter-frequency neighboring cells based on the average interference noise value of each target inter-frequency neighboring cell and the interference noise threshold of each target inter-frequency neighboring cell.

[0061] Among them, the average interference noise value of the target cell is less than the interference noise threshold of the target cell, and the target difference of the target cell is greater than the target difference of other target inter-frequency neighboring cells in at least one target inter-frequency neighboring cell.

[0062] It is worth noting that the target difference is the difference between the average interference noise value of a target inter-frequency neighboring cell and the interference noise threshold of a target inter-frequency neighboring cell.

[0063] As one possible implementation, the above S204 implementation process can be as follows: when the average interference noise value of the target inter-frequency neighbor cell is greater than the interference noise threshold of the target inter-frequency neighbor cell, the serving cell determines the target inter-frequency neighbor cell as the non-handover target cell.

[0064] When the average interference noise value of the target inter-frequency neighboring cell is less than the interference noise threshold of the target inter-frequency neighboring cell, the serving cell calculates and determines the difference between the average interference noise value of the target inter-frequency neighboring cell and the interference noise threshold of the target inter-frequency neighboring cell, and determines the target inter-frequency neighboring cell with the largest difference as the handover target cell.

[0065] For example, if the average interference noise value of inter-frequency neighboring cell A is -105dBm, which is less than the interference noise threshold of inter-frequency neighboring cell A, which is -89dBm, the serving cell calculates and determines the target difference value of inter-frequency neighboring cell A to be 16.

[0066] When the average interference noise value of neighboring cell B is -108dBm, which is less than the interference noise threshold of neighboring cell B, which is -91dBm, the serving cell calculates and determines the target difference value of neighboring cell B to be 17.

[0067] If the target difference 16 of inter-frequency neighboring cell A is determined to be less than the target difference 17 of inter-frequency neighboring cell B, then the serving cell determines inter-frequency neighboring cell B as the handover target cell.

[0068] S205. The serving cell sends a handover instruction to the terminal device. Correspondingly, the terminal device receives the handover instruction sent by the serving cell.

[0069] The handover instruction information is used to instruct the terminal device to initiate a handover to the target cell.

[0070] Referring to the example in S204, the serving cell sends a handover instruction to the terminal device, indicating that the inter-frequency neighboring cell B is the target cell for handover. The terminal device will then initiate a handover to the inter-frequency neighboring cell B.

[0071] Based on the above technical solution, this application provides a device handover method. First, the terminal device determines at least one target inter-frequency neighbor cell, wherein the signal quality of the target inter-frequency neighbor cell is greater than a first threshold, indicating that the signal conditions of the target inter-frequency neighbor cell are good. Then, the terminal device determines the interference noise threshold of the at least one target inter-frequency neighbor cell. Next, the terminal device sends the interference noise threshold of the at least one target inter-frequency neighbor cell to the serving cell. The serving cell determines the target difference of each target inter-frequency neighbor cell based on the average interference noise value of each target inter-frequency neighbor cell and the interference noise threshold of each target inter-frequency neighbor cell. The target inter-frequency neighbor cell with the largest target difference is determined as the handover target cell. A large target difference indicates that the signal quality of the target inter-frequency neighbor cell can cover the interference noise value, ensuring that the terminal device is not affected by interference noise. Therefore, the serving cell sends the handover instruction information of the handover target cell to the terminal device, instructing the terminal device to initiate a handover to the handover target cell, thereby ensuring a reasonable handover of the terminal device and improving the communication quality of the terminal device.

[0072] The device switching method provided in the embodiments of this application has been described in detail above.

[0073] In one possible implementation, combining Figure 2 ,like Figure 3 As shown, before determining at least one target inter-frequency neighbor cell and the interference noise threshold of each target inter-frequency neighbor cell in S201 above, the electronic device also needs to determine the signal quality of the inter-frequency neighbor cells of the serving cell, which can be achieved through the following S301-S303.

[0074] S301. The terminal device sends a first request message to the serving cell. Correspondingly, the serving cell receives the first request message sent by the terminal device.

[0075] The first request message is used to request frequency point information and measurement configuration of the serving cell's inter-frequency neighboring cells.

[0076] It is worth noting that when the average interference noise value of the serving cell is greater than the interference noise threshold of the serving cell, a first request message is sent to the serving cell.

[0077] As one possible implementation, the above S301 can be achieved through the following process: the terminal device presets the interference noise threshold of the serving cell, and when the average interference noise value of the serving cell is less than the interference noise threshold of the serving cell, the terminal device does not perform any processing action.

[0078] If the terminal device detects that the average interference noise value of the serving cell is greater than the interference noise threshold of the serving cell, the terminal device believes that the reason for the high packet loss rate despite good signal conditions in the serving cell is that the interference noise of the serving cell is too high. Therefore, the terminal device will send a first request message to the serving cell to request the frequency point information and measurement configuration of the inter-frequency neighboring cells of the serving cell.

[0079] This includes the frequency point information of the inter-frequency neighboring cell to the downlink frequency point of the inter-frequency neighboring cell, such as: downlink frequency point 300, downlink frequency point 100, and downlink frequency point 1650. The measurement configuration of the inter-frequency neighboring cell includes, but is not limited to: the object to be measured by the terminal device (frequency point and PCI information), the reporting method, the measurement identifier, and the event parameters.

[0080] For example, the terminal device presets the interference noise threshold of the serving cell to be -88dBm. The average interference noise value of the serving cell is -70dBm, which is greater than the interference noise threshold of the serving cell to be -88dBm. The terminal device requests the serving cell to send frequency point information and measurement configuration of multiple inter-frequency neighboring cells.

[0081] S302. The serving cell sends a first response message to the terminal device. Correspondingly, the terminal device receives the first response message sent by the serving cell.

[0082] The first response information contains frequency information and measurement configuration of the serving cell's inter-frequency neighboring cells.

[0083] For example, the serving cell sends the frequency information and measurement configuration of inter-frequency neighboring cells A, B, and C to the serving cell of the terminal device.

[0084] The frequency information and measurement configuration of inter-frequency neighboring cells can be understood as facilitating the serving cell to identify inter-frequency neighboring cells.

[0085] S303. Based on the first response information, the terminal device measures the inter-frequency neighboring cells of the serving cell to determine the signal quality of the inter-frequency neighboring cells of the serving cell.

[0086] Referring to the example in S302, the terminal device measures inter-frequency neighboring cell A, inter-frequency neighboring cell B, and inter-frequency neighboring cell C, and determines that the signal quality of inter-frequency neighboring cell A is -86dBm, the signal quality of inter-frequency neighboring cell B is -88dBm, and the signal quality of inter-frequency neighboring cell C is -101dBm.

[0087] Based on the above technical solution, the terminal equipment determines the signal quality of the inter-frequency neighboring cells of the serving cell, in order to prepare for whether the inter-frequency neighboring cells meet the handover conditions.

[0088] In one possible implementation, combining Figure 2 ,like Figure 4As shown in the above S301, before the terminal device sends the first request message to the serving cell, the electronic device also needs to determine the average interference noise value of the serving cell, which can be achieved through the following S401-S403.

[0089] S401. The terminal device determines the signal quality and current packet loss rate of the serving cell.

[0090] In one possible implementation, the terminal device is equipped with a network quality awareness module, which is used to evaluate the matching between network quality and the user's actual perception.

[0091] For example, terminal device A determines, through the network quality awareness module, that the signal quality of the serving cell of terminal device A is -85dBm and the current uplink packet loss rate is 30%.

[0092] It is worth noting that the signal quality of the serving cell can be measured by the Reference Signal Receiving Power (RSRP).

[0093] S402. When the signal quality of the serving cell is greater than the signal threshold and the current packet loss rate of the serving cell is greater than the packet loss rate threshold, the terminal device sends a second request message to the serving cell. Correspondingly, the serving cell receives the second request message sent by the terminal device.

[0094] The second request message is used to request the average interference noise value of the serving cell.

[0095] Referring to the example in S401, the terminal device presets the signal threshold of the serving cell to be -95dBm and the packet loss rate threshold to be 15%. When the terminal device detects that the signal quality of the serving cell is -85dBm, which is stronger than the signal threshold of the serving cell to be -95dBm, it determines that the signal conditions of the serving cell are good.

[0096] When the terminal device detects that the current packet loss rate of the serving cell is 30%, which is higher than the packet loss rate threshold of 15%, the ability to determine the true serving cell is poor.

[0097] Therefore, when the signal conditions of the serving cell are good but the actual perception capability is poor, the terminal device sends a request message to the serving cell, requesting the serving cell to send its own average interference noise value.

[0098] S403. The serving cell sends a second response message to the terminal device. Correspondingly, the terminal device receives the second response message sent by the serving cell.

[0099] The second response information contains the average interference noise value of the serving cell.

[0100] Referring to the example in S402, the serving cell sends its average interference noise value of -70dBm to the terminal device.

[0101] Based on the above technical solution, if the terminal device determines that the communication conditions of the serving cell cannot meet its own needs, and determines that the poor communication of the serving cell is due to excessive interference noise, then the terminal device requests the average interference noise value from the serving cell to prepare for subsequent handover to a neighboring cell of a different frequency.

[0102] This application embodiment can divide an electronic device into functional modules or functional units according to the above method examples. For example, each function can be divided into its own functional modules or functional units, or two or more functions can be integrated into one processing module. The integrated module can be implemented in hardware or as a software functional module or functional unit.
