Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a device switching method, electronic device, and storage medium. Background Technology

[0002] In related technologies, when a carrier wave is affected by external interference, the interference noise level can become excessively high. If a terminal device communicates under a carrier with excessively high interference noise, the communication quality will be poor. In this case, the terminal device will switch to a carrier with lower interference noise to ensure communication quality. However, if the carrier with lower interference noise is overloaded, the terminal device's service perception capability will still be impaired. Therefore, how to rationally switch terminal devices is a problem that urgently needs to be solved. Summary of the Invention

[0011] In conjunction with the second aspect, in one possible implementation, the processing unit is specifically configured to: determine multiple carriers; the multiple carriers are multi-frequency carriers with the same coverage; obtain the average interference noise value and physical resource utilization rate of each of the multiple carriers; determine the carrier among the multiple carriers whose average interference noise value is less than the interference noise threshold and whose physical resource utilization rate is greater than a first physical resource threshold as the first carrier; and determine the carrier among the multiple carriers whose average interference noise value is greater than or equal to the interference noise threshold and whose physical resource utilization rate is less than a second physical resource threshold as the second carrier.

Next, based on the anti-interference noise value, the electronic device determines the target user terminal to be switched and the target switching carrier. Finally, the target user terminal is switched to the target switching carrier, thereby ensuring that the user terminal's service perception is not affected by external factors, and also ensuring that the electronic device can switch the terminal device reasonably.

[0027] The device switching method and device provided in the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0028] 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.

[0029] 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.

[0030] 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.

[0031] 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.

[0032] Currently, when a communication base station encounters external interference, the carrier under the base station will experience high interference noise. Operators typically address this by adjusting base station parameters through measures such as blocking, reducing power, and suppressing the base station's downtilt angle. However, these measures can severely impair base station performance and hinder the maximization of base station resource utilization. Another approach is to first determine the pilot strength information of users switching in the serving cell, then determine the interference weight value of interference information from neighboring cells based on the pilot strength information, and finally balance the interference information from neighboring cells based on the interference weight value. This approach can only address interference from neighboring cells within the system to the serving cell and cannot handle external interference.

[0033] In related technologies, when a carrier within a base station is affected by external interference, the base station's demodulation capability for user terminal data information decreases, leading to problems such as high bit error rate, low data rate, high latency, and poor service perception at the user terminal. In this situation, the terminal device will switch to a carrier with less interference noise to ensure communication quality. However, if the carrier with less interference noise is overloaded, it will still impair the service perception capability of the terminal device. Therefore, how to rationally switch terminal devices is a problem that urgently needs to be solved.

[0034] To address the problems in the prior art, this application provides a device handover method. The method includes: First, an electronic device determines at least one first carrier and at least one second carrier. Because the first carrier, with low interference noise, has excessive load, affecting the user terminal's service perception, a qualified user terminal needs to be switched to the second carrier, which has high interference noise but low load, ensuring normal communication for the user terminal on both carriers. Next, the electronic device determines the anti-interference noise value of the first user terminal on each first carrier for each second carrier. Then, based on the anti-interference noise value, the electronic device determines the target user terminal to be switched and the target switching carrier. Finally, the target user terminal is switched to the target switching carrier, thereby ensuring that the user terminal's service perception is not affected by external factors, and also ensuring that the electronic device performs reasonable handover of terminal devices.

[0035] Figure 1 This is a schematic diagram of the structure of an electronic device provided in an embodiment of this application, such as... Figure 1 As shown, the electronic device 100 includes at least one processor 101, a communication line 102, and at least one communication interface 104, and may also include a memory 103. The processor 101, memory 103, and communication interface 104 are connected to each other via the communication line 102.

[0036] The processor 101 may be a central processing unit (CPU), an application-specific integrated circuit (ASIC), or one or more integrated circuits configured to implement the embodiments of this application, such as one or more digital signal processors (DSPs), or one or more field-programmable gate arrays (FPGAs).

[0037] Communication line 102 may include a path for transmitting information between the aforementioned components.

[0038] The communication interface 104 is used to communicate with other devices or communication networks. It can use any transceiver-like device, such as Ethernet, radio access network (RAN), wireless local area network (WLAN), etc.

[0039] The memory 103 may be a read-only memory (ROM) or other type of static storage device capable of storing static information and instructions, random access memory (RAM) or other type of dynamic storage device capable of storing information and instructions, or electrically erasable programmable read-only memory (EEPROM), compact disc read-only memory (CD-ROM) or other optical disc storage, optical disc storage (including compressed optical discs, laser discs, optical discs, digital universal optical discs, Blu-ray discs, etc.), magnetic disk storage media or other magnetic storage devices, or any other medium capable of including or storing desired program code having the form of instructions or data structures and accessible by a computer, but not limited thereto.

[0040] In one possible design, the memory 103 can exist independently of the processor 101, meaning the memory 103 can be an external memory of the processor 101. In this case, the memory 103 can be connected to the processor 101 via the communication line 102 to store execution instructions or application code, and its execution is controlled by the processor 101 to implement the network quality determination method provided in the following embodiments of this application. In another possible design, the memory 103 can also be integrated with the processor 101, meaning the memory 103 can be an internal memory of the processor 101. For example, the memory 103 can be a cache, which can be used to temporarily store some data and instruction information.

[0041] As one possible implementation, processor 101 may include one or more CPUs, for example Figure 1 CPU0 and CPU1 in the example. Alternatively, the electronic device 100 may include multiple processors, such as... Figure 1 The processors 101 and 107 are included. Alternatively, the electronic device 100 may also include an output device 105 and an input device 106.

[0042] 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.

[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 In the electronic device shown, the device switching method provided in this application embodiment can be implemented through the following steps.

[0044] S201, The electronic device determines at least one first carrier and at least one second carrier.

[0045] Wherein, the first carrier is a carrier whose average interference noise value is less than the interference noise threshold and whose load is greater than the first load threshold; the second carrier is a carrier whose average interference noise value is greater than the interference noise threshold and whose load is less than the second load threshold; the second carrier is a different frequency carrier that is covered by the first carrier.

[0046] In one possible implementation, when there is one or more first carriers, the user terminals under the first carrier need to be switched and adjusted, that is, the service balancing procedure needs to be started.

[0047] For example, an electronic device may identify carrier A with low interference noise and high load, carrier B with high interference noise and low load, and carrier C with high interference noise and low load.

[0048] S202, The electronic equipment determines the anti-interference noise value of the first user terminal in each first carrier in each second carrier.

[0049] As one possible implementation, the above S202 can be implemented as follows: because the interference noise of the first carrier is small, the user terminals switch to the first carrier one after another. There are multiple first user terminals under one first carrier, which leads to the overload of the first carrier and affects the communication quality of the user terminals; then the electronic equipment determines the anti-interference noise value of multiple user terminals under the first carrier on other carriers.

[0050] Referring to the example in S201, the electronic device determines that the anti-interference noise value of user terminal A on carrier B is 28, the anti-interference noise value of user terminal A on carrier C is 20, the anti-interference noise value of user terminal B on carrier B is 15, and the anti-interference noise value of user terminal B on carrier C is 21.

[0051] S203. The electronic equipment determines the target handover user terminal and the target handover carrier based on the anti-interference noise value.

[0052] Among them, the anti-interference noise value of the target handover user terminal on the target handover carrier is the maximum anti-interference noise value.

[0053] In one possible implementation, the electronic device sorts the anti-interference noise values ​​of user terminals on each second carrier, determines the user terminal with the largest anti-interference noise value as the target handover user terminal, and the carrier corresponding to the target handover user terminal is the target handover carrier.

[0054] Referring to the example in S202, the electronic device sorts the anti-interference noise value 28 of user terminal A on carrier B, the anti-interference noise value 20 of user terminal A on carrier C, the anti-interference noise value 15 of user terminal B on carrier B, and the anti-interference noise value 21 of user terminal B on carrier C, and determines that user terminal A is the target handover user terminal and carrier B is the target handover carrier.

[0055] S204. The electronic device sends a handover instruction to the target user terminal.

[0056] The handover indication information is used to instruct the target handover user terminal to initiate a handover to the target handover carrier.

[0057] Referring to the example in S605, the electronic device sends a handover instruction to user terminal A, indicating that carrier B is the target carrier for handover, and user terminal A will initiate a handover to carrier B.

[0058] Based on the above technical solution, the present application provides a device switching method. First, the electronic device determines at least one first carrier and at least one second carrier. Because the first carrier with low interference noise has excessive load, affecting the user terminal's service perception, the qualified user terminal needs to be switched to the second carrier with high interference noise but low load to ensure that the user terminal can communicate normally under both carriers. Then, the electronic device determines the anti-interference noise value of the first user terminal in each first carrier in each second carrier. Next, based on the anti-interference noise value, the electronic device determines the target user terminal to be switched and the target switching carrier. Finally, the target user terminal is switched to the target switching carrier, thereby ensuring that the user terminal's service perception is not affected by external factors, and also ensuring that the electronic device switches the terminal device reasonably.

[0059] The device switching method provided in the embodiments of this application has been described in detail above.

[0060] In one possible implementation, combining Figure 2 ,like Figure 3 As shown, in S201 above, the electronic device determines at least one first carrier and at least one second carrier, which can be specifically achieved through the following S301-S304.

[0061] S301, Electronic equipment determines multiple carriers.

[0062] Among them, multiple carriers are different frequency carriers with the same coverage.

[0063] In one possible implementation, the electronic device in this application can be a serving cell.

[0064] S302. Electronic equipment acquires the average interference noise value and physical resource utilization rate of each carrier among multiple carriers.

[0065] For example, to avoid uneven load distribution among multiple carriers within a preset period, the electronic device periodically acquires the average interference noise value of carrier A as -95dBm and the physical resource utilization rate as 80%, the average interference noise value of carrier B as -115dBm and the physical resource utilization rate as 60%, and the average interference noise value of carrier C as -120dBm and the physical resource utilization rate as 50%.

[0066] S303. The electronic device determines that among multiple carriers, the carrier with an average interference noise value less than the interference noise threshold and a physical resource utilization rate greater than the first physical resource threshold is the first carrier.

[0067] Referring to the example in S302, the electronic device compares the average interference noise value of carrier A, -95dBm, with the interference noise threshold, -105dBm, and compares the physical resource utilization rate of carrier A, 80%, with the first physical resource threshold, 65%, to determine that carrier A is a carrier with low interference noise and high load.

[0068] S304. The electronic device determines that among multiple carriers, the carrier with an average interference noise value greater than or equal to the interference noise threshold and a physical resource utilization rate less than the second physical resource threshold is the second carrier.

[0069] Referring to the example in S302, the electronic device compares the average interference noise value of carrier B, -115dBm, with the interference noise threshold, -105dBm, and compares the physical resource utilization rate of carrier B, 60%, with the first physical resource threshold, 65%, to determine that carrier B is a carrier with high interference noise and low load.

[0070] The electronic device compares the average interference noise value of carrier C (-120dBm) with the interference noise threshold (-105dBm) and compares the physical resource utilization rate of carrier C (50%) with the first physical resource threshold (65%) to determine that carrier C is a carrier with high interference noise and low load.

[0071] Based on the above technical solution, the electronic device in this application accurately determines the carrier under different conditions, providing a favorable basis for the subsequent handover of user terminals.

[0072] In one possible implementation, combining Figure 2 ,like Figure 4 As shown, the anti-interference noise value of a first user terminal on a second carrier can be specifically determined through the following steps S401-S402:

[0073] S401. When a first user terminal accesses a second carrier, the electronic device obtains the signal quality and average interference noise value of the second carrier.

[0074] In one possible implementation, the first user terminal is a user terminal on the first carrier. Because the load on the first carrier is too high, it is considered to switch the user terminal on the first carrier to the second carrier with a lower load. Therefore, the electronic device obtains the RSRP value and average interference noise value of the second carrier when the first user terminal on the first carrier accesses the second carrier.

[0075] Referring to the examples in S303 and S304, when user terminal A in carrier A accesses carrier B, the signal quality of carrier B is -80dBm and the average interference noise value is -108dBm.

[0076] When user terminal A in carrier A accesses carrier C, the signal quality of carrier C is -90dBm and the average interference noise value is -105dBm.

[0077] Referring to the examples in S303 and S304, when user terminal B in carrier A accesses carrier B, the signal quality of carrier B is -78dBm and the average interference noise value is -108dBm.

[0078] When user terminal B in carrier A accesses carrier C, the signal quality of carrier C is -88dBm and the average interference noise value is -105dBm.

[0079] S402. The electronic device determines the difference between the signal quality of a first user terminal accessing a second carrier and the average interference noise value of the second carrier as the anti-interference noise value of the first user terminal on the second carrier.

[0080] Referring to the example in S401, the electronic device subtracts the signal quality of carrier B -80dBm from the average interference noise value -108dBm to determine that the anti-interference noise value of user terminal A on carrier B is 28.

[0081] The electronic device subtracts the signal quality of carrier C (-85dBm) from the average interference noise value (-105dBm) to determine that the anti-interference noise value of user terminal A on carrier C is 20.

[0082] The electronic device subtracts the signal quality of carrier B (-90dBm) from the average interference noise value (-108dBm) to determine that the anti-interference noise value of user terminal A on carrier B is 18.

[0083] The electronic device subtracts the signal quality of carrier C (-93dBm) from the average interference noise value (-105dBm) to determine that the anti-interference noise value of user terminal A on carrier C is 12.

[0084] Based on the above technical solution, this application determines the anti-interference noise value of a first user terminal on a second carrier by measuring the difference between the signal quality of a first user terminal accessing a second carrier and the average interference noise value of the second carrier. In this way, the anti-interference noise values ​​of multiple user terminals under the first carrier when accessing different second carriers are determined, providing reliable information for subsequent user terminal handover.

[0085] In one possible implementation, combining Figure 2 ,like Figure 5 As shown, in the above S203, the electronic equipment determines the target handover user terminal and the target handover carrier based on the anti-interference noise value, which can be specifically achieved through the following S501-S503.

[0086] S501, The electronic device determines the anti-interference threshold of the first user terminal.

[0087] For example, the electronic device determines the anti-interference threshold to be 20.

[0088] S502. The electronic device identifies multiple alternative user terminals whose anti-interference noise values ​​are greater than the anti-interference threshold.

[0089] In one possible implementation, in a real-world scenario, there may be too many first user terminals under the first carrier. Therefore, the anti-interference noise values ​​of multiple first user terminals are compared with the anti-interference threshold, and some user terminals that do not meet the threshold are filtered out to determine multiple candidate user terminals with anti-interference noise values ​​greater than the anti-interference threshold.

[0090] Based on the examples in S402 and S501, the electronic device compares the anti-interference noise value 28 of user terminal A on carrier B with the anti-interference threshold 20 to determine user terminal A as a candidate user terminal.

[0091] The electronic device compares the anti-interference noise value 20 of user terminal A on carrier C with the anti-interference threshold 20 to determine user terminal A as a candidate user terminal.

[0092] The electronic device compares the anti-interference noise value 18 of user terminal B on carrier B with the anti-interference threshold 20 to determine that user terminal B is not a candidate user terminal.

[0093] The electronic device compares the anti-interference noise value 12 of user terminal B on carrier C with the anti-interference threshold 20 to determine that user terminal B is not a candidate user terminal. This application does not limit the above data.

[0094] S503. The electronic equipment sorts the anti-interference noise values ​​of multiple candidate user terminals and determines the candidate user terminal with the largest anti-interference noise value as the target handover user terminal.

[0095] Among them, the carrier corresponding to the maximum anti-interference noise value is the target switching carrier.

[0096] Referring to the example in S502, the electronic device sorts the anti-interference noise values ​​of user terminal A and determines that user terminal A corresponding to the maximum anti-interference noise value 28 is the target handover user terminal; while carrier B corresponding to the maximum anti-interference noise value 28 is the target handover carrier.

[0097] Based on the above technical solution, since there are too many user terminals under the first carrier, this application compares the anti-interference noise value of the user terminal access carrier with the anti-interference threshold to screen out some user terminals that do not meet the requirements, which is more conducive to the equipment effectively and quickly determining the target user terminal and the target switching carrier.

[0098] In one possible implementation, combining Figure 2 ,like Figure 6 As shown, before the electronic device determines at least one first carrier and at least one second carrier in S201, the user terminal can be switched to a carrier with less interference noise, which can be achieved through the following S601-S606.

[0099] S601. The electronic device obtains the signal quality and average interference noise value of the first service carrier when the second user terminal accesses the first service carrier.

[0100] In one possible implementation, the first serving carrier is the carrier where the second user terminal is located, and the electronic device periodically acquires the signal quality and average interference noise value of the carrier when the user terminal accesses the carrier.

[0101] For example, the electronic device obtains that the signal quality of carrier D of user terminal B is -100dBm and the average interference noise value is -95dBm.

[0102] S602. The electronic device determines the anti-interference noise value of the second user terminal on the first service carrier based on the signal quality and average interference noise value of the first service carrier.

[0103] Referring to the example in S601, the signal quality of carrier D -100dBm is subtracted from the average interference noise value -95dBm to determine that the anti-interference noise value of user terminal B on carrier D is -5.

[0104] S603. The electronic device determines whether the anti-interference noise value of the second user terminal on the first serving carrier is less than the anti-interference standard value.

[0105] Referring to the example in S602, the electronic device determines whether the anti-interference noise value -5 of user terminal B on carrier D is less than the anti-interference standard value 2.

[0106] S604. If it is less than, the electronic device determines the anti-interference noise value of the second user terminal on multiple second service carriers.

[0107] Referring to the example in S603, the anti-interference noise value of user terminal B on carrier D, -5, is less than the anti-interference standard value of 2. This indicates that the service experience of user terminal B is significantly affected by interference, and user terminal B needs to be migrated to a carrier with less interference as soon as possible. Therefore, the electronic equipment determines the anti-interference noise value of user terminal B on other serving carriers. For example, through S601-S602, the anti-interference noise value of user terminal B on carrier E is determined to be 1, the anti-interference noise value on carrier F is 6, and the anti-interference noise value on carrier G is 10.

[0108] S605. The electronic equipment sorts the anti-interference noise values ​​of multiple second service carriers and determines the second service carrier corresponding to the maximum anti-interference noise value as the pre-switching carrier.

[0109] Referring to the example in S604, the electronic device sorts the anti-interference noise value 1 of user terminal B on carrier E, the anti-interference noise value 6 of user terminal B on carrier F, and the anti-interference noise value 10 of user terminal B on carrier G, and determines the carrier G corresponding to the maximum anti-interference noise value 10 as the carrier to be switched.

[0110] S606. The electronic device sends a handover instruction to the user terminal.

[0111] The handover indication information is used to instruct the user terminal to initiate a handover to the carrier to be handed over.

[0112] Referring to the example in S605, the electronic device sends a handover indication message that carrier G is the carrier to be switched to to user terminal B, and user terminal B will initiate a handover to carrier G.
