Currently, when a communication base station encounters external interference, the carrier under the base station has the problem of higher interference noise, and the common operator processes the problem of adjusting the parameters of the base station through measures such as locking, reducing power, inhibiting the downward inclination angle of the base station, but the measures easily cause serious damage to the efficiency of the base station, and are unfavorable for the maximized utilization of the base station resources; another measure is: firstly, pilot frequency intensity information of a switching user in a service cell is determined, then, an interference weight value of interference information of each adjacent cell is determined according to the pilot frequency intensity information, and finally, the interference information of each adjacent cell is balanced according to the interference weight value.

In the related art, when the carrier wave in the base station is affected by external interference, the demodulation capability of the base station to the data information of the user terminal is reduced, and the problems of high error rate, low rate and poor time-delay high-energy service perceptibility occur when the data transmission of the user terminal is affected. At this time, the terminal equipment is switched to the carrier with small interference noise, so as to ensure the communication quality; meanwhile, the excessive load of a plurality of carrier waves with small interference noise still causes the service perception capability of the terminal equipment to be damaged.

As shown in fig. 2, a flowchart of a device switching method provided by an embodiment of the present application is shown, where the device switching method provided by the embodiment of the present application may be applied to an electronic device shown in fig. 1, and the device switching method provided by the embodiment of the present application may be implemented by the following steps.

S201, the electronic device determines at least one first carrier and at least one second carrier.

The first carrier is a carrier with an average interference noise value smaller than an interference noise threshold value and a load larger than a first load threshold value; the second carrier is a carrier with an average interference noise value larger than an interference noise threshold and a load smaller than a second load threshold; the second carrier is a different frequency carrier covered by the first carrier.

In one possible implementation, when one or more first carriers exist, a handover adjustment is required for the ue under the first carrier, that is, a service equalization procedure is started.

Illustratively, the electronic device determines 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.

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

As a possible implementation manner, the implementation manner of S202 may be: because the first carrier interference noise is small, the user terminals are switched to the first carrier in a dispute way, and a plurality of first user terminals exist under one first carrier, so that the load of the first carrier is too high, and the communication quality of the user terminals is affected; the electronic device determines the interference noise immunity values of the plurality of user terminals on the other carriers under the first carrier.

In combination with the example in S201, the electronic device determines that the antijam noise value of the user terminal a on the carrier B is 28, the antijam noise value of the user terminal a on the carrier C is 20, the antijam noise value of the user terminal B on the carrier B is 15, and the antijam noise value of the user terminal B on the carrier C is 21.

S203, the electronic equipment determines the target switching user terminal and the target switching carrier based on the anti-interference noise value.

The anti-interference noise value of the target switching user terminal in the target switching carrier is the maximum anti-interference noise value in the anti-interference noise values.

In one possible implementation manner, the electronic device ranks the anti-interference noise values of the user terminals on the second carriers, determines the user terminal with the largest anti-interference noise value as the target handover user terminal, and uses the carrier corresponding to the target handover user terminal as the target handover carrier.

In combination with the example in S202, the electronic device sorts the antijam noise value 28 of the user terminal a on the carrier B, the antijam noise value 20 of the user terminal a on the carrier C, the antijam noise value 15 of the user terminal B on the carrier B, and the antijam noise value 21 of the user terminal B on the carrier C, so as to determine that the user terminal a is the target handover user terminal, and the carrier B is the target handover carrier.

S204, the electronic equipment sends switching indication information to the target switching user terminal.

The switching indication information is used for indicating the target switching user terminal to initiate switching to the target switching carrier.

In combination with the example in S605, the electronic device sends the handover indication information that carrier B is the target handover carrier to user terminal a, and user terminal a will initiate handover to carrier B.

Based on the above technical solution, in the device switching method provided by the embodiment of the present application, first, the electronic device determines at least one first carrier and at least one second carrier, and the service perception of the ue is affected by the overload of the first carrier with low interference noise, so that the ue that meets the conditions needs to be switched to the second carrier with high interference noise and low load, thereby ensuring that the ue can perform normal communication under both carriers; and then the electronic equipment determines the anti-interference noise value of the first user terminal in each first carrier wave in each second carrier wave, and then the electronic equipment determines the target switching user terminal and the target switching carrier wave based on the anti-interference noise value, and finally the target switching user terminal is switched into the target switching carrier wave, so that the service perception of the user terminal is not influenced by the outside, and meanwhile, the electronic equipment is ensured to reasonably switch the terminal equipment.

The device switching method provided by the embodiment of the application is described in detail above.

In a possible implementation manner, as shown in fig. 3 in connection with fig. 2, the determining, by the above-mentioned S201, the at least one first carrier and the at least one second carrier by the electronic device may be specifically implemented by the following S301-S304.

S301, the electronic device determines a plurality of carriers.

Wherein the plurality of carriers are pilot frequency carriers covered by the same carrier.

In one possible implementation, the electronic device in the present application may be a serving cell.

S302, the electronic equipment acquires the average interference noise value and the physical resource utilization rate of each carrier in the plurality of carriers.

For example, in order to avoid the situation that the loads of a plurality of carriers are uneven in a preset period, the electronic device periodically obtains that the average interference noise value of the carrier a is-95 dBm and the utilization rate of physical resources is 80%, the average interference noise value of the carrier B is-115 dBm and the utilization rate of physical resources is 60%, and the average interference noise value of the carrier C is-120 dBm and the utilization rate of physical resources is 50%.

S303, the electronic device determines a carrier with an average interference noise value smaller than an interference noise threshold and a physical resource utilization rate larger than a first physical resource threshold from the plurality of carriers as a first carrier.

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

S304, the electronic device determines a carrier with an average interference noise value larger than or equal to an interference noise threshold value and a physical resource utilization rate smaller than a second physical resource threshold value from the plurality of carriers as a second carrier.

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

The electronic equipment compares the average interference noise value of the carrier C of-120 dBm with an interference noise threshold of-105 dBm, compares the physical resource utilization rate of the carrier C of 50% with a first physical resource threshold of 65%, and determines that the carrier C is a carrier with large interference noise and low load.

Based on the technical scheme, the electronic equipment accurately determines the carrier waves in different conditions, and provides a favorable basis for the switching of the subsequent user terminals.

In a possible implementation manner, as shown in fig. 4 in conjunction with fig. 2, the antijam noise value of a first ue on a second carrier may be specifically determined by the following S401-S402:

s401, when the electronic equipment acquires that a first user terminal accesses a second carrier, the signal quality and the average interference noise value of the second carrier are obtained.

In one possible implementation manner, the first ue is a ue in the first carrier, and because the load of the first carrier is too high, the ue in the first carrier is considered to be switched to the second carrier with low load, so the electronic device obtains the RSRP value and the average interference noise value of the second carrier when the first ue in the first carrier accesses the second carrier.

In combination with the examples in S303 and S304, when the user terminal a in the carrier a accesses the carrier B, the signal quality of the carrier B is-80 dBm, and the average interference noise value is-108 dBm.

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

In combination with the examples in S303 and S304, when the user terminal B in the carrier a accesses the carrier B, the signal quality of the carrier B is-78 dBm, and the average interference noise value is-108 dBm.

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

S402, the electronic device determines a difference value between the signal quality of a first user terminal accessing a second carrier and the average interference noise value of the second carrier, and the difference value is an anti-interference noise value of the first user terminal at the second carrier.

In combination with the example in S401, the electronic device subtracts the signal quality-80 dBm of the carrier B from the average interference noise value-108 dBm, and determines that the anti-interference noise value of the user terminal a at the carrier B is 28.

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

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

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

Based on the technical scheme, the application determines the anti-interference noise value of a first user terminal on a second carrier through the difference value between the signal quality of the first user terminal accessing to the second carrier and the average interference noise value of the second carrier, so as to determine the anti-interference noise values of a plurality of user terminals under the first carrier when accessing to different second carriers, and provide reliable information for the switching of subsequent user terminals.

In a possible implementation manner, as shown in fig. 5 in connection with fig. 2, S203, the electronic device determines the target handover user terminal and the target handover carrier based on the anti-interference noise value, which may be specifically implemented by the following S501-S503.

S501, the electronic equipment determines an anti-interference threshold of the first user terminal.

Illustratively, the electronic device determines the tamper threshold to be 20.

S502, the electronic equipment determines a plurality of alternative user terminals with anti-interference noise values larger than an anti-interference threshold value.

In a possible implementation manner, in an actual scenario, there may be too many first user terminals under the first carrier, so that the anti-interference noise values of the first user terminals are compared with the anti-interference threshold, a part of user terminals that do not meet the anti-interference threshold are screened out, and a plurality of candidate user terminals with anti-interference noise values greater than the anti-interference threshold are determined.

In combination with the examples in S402 and S501, the electronic device compares the antijam noise value 28 of the user terminal a on the carrier B with the antijam threshold 20, and determines that the user terminal a is an alternative user terminal.

The electronic device compares the anti-interference noise value 20 of the user terminal a on the carrier C with the anti-interference threshold 20, and determines that the user terminal a is an alternative user terminal.

The electronic device compares the anti-interference noise value 18 of the user terminal B at the carrier B with the anti-interference threshold 20, and determines that the user terminal B is not an alternative user terminal.

The electronic device compares the anti-interference noise value 12 of the user terminal B at the carrier C with the anti-interference threshold 20, and determines that the user terminal B is not an alternative user terminal. The present application is not limited to the above data.

S503, the electronic equipment sorts the anti-interference noise values of the plurality of alternative user terminals, and determines the alternative user terminal corresponding to the maximum anti-interference noise value as the target switching user terminal.

The carrier corresponding to the maximum anti-interference noise value is the target switching carrier.

In combination with the example in S502, the electronic device ranks the anti-interference noise values of the user terminals a, and determines the user terminal a corresponding to the maximum anti-interference noise value 28 as the target handover user terminal; and carrier B corresponding to the maximum antijam noise value 28 is the target switching carrier.

Based on the technical scheme, because the number of the user terminals under the first carrier is excessive, the application screens a part of non-conforming user terminals by comparing the anti-interference noise value of the user terminal access carrier with the anti-interference threshold value, thereby being more beneficial to effectively and rapidly determining the target switching user terminal and the target switching carrier.

In a possible implementation manner, as shown in fig. 2, before the electronic device determines at least one first carrier and at least one second carrier in S201 and as shown in fig. 6, the ue may be further switched to a carrier with low interference noise, which may be specifically implemented by the following S601-S606.

S601, the electronic equipment acquires the signal quality and the average interference noise value of the first service carrier when the second user terminal is accessed to the first service carrier.

In one possible implementation manner, the first service carrier is a carrier where the second user terminal is located, and when the electronic device periodically acquires the user terminal access carrier, the signal quality and the average interference noise value of the carrier.

The electronic device obtains the signal quality of the carrier D of-100 dBm and the average interference noise value of-95 dBm when the user terminal B is on the carrier D.

S602, the electronic equipment determines an anti-interference noise value of the second user terminal on the first service carrier based on the signal quality and the average interference noise value of the first service carrier.

In combination with the example in S601, subtracting the signal quality of-100 dBm of the carrier D from the average interference noise value of-95 dBm determines that the anti-interference noise value of the user terminal B on the carrier D is-5.

S603, the electronic device judges whether the anti-interference noise value of the second user terminal on the first service carrier is smaller than an anti-interference standard value.

In combination with the example in S602, the electronic device determines whether the antijam noise value-5 of the user terminal B on the carrier D is smaller than the antijam standard value 2.

And S604, if the interference noise value is smaller than the second service carrier, the electronic equipment determines the interference noise resistance value of the second user terminal on a plurality of second service carriers.

In combination with the example in S603, the anti-interference noise value-5 of the ue B on the carrier D is smaller than the anti-interference standard value 2, which indicates that the service experience of the ue B is greatly affected by interference at this time, and the ue B needs to be migrated to the carrier with smaller interference as soon as possible; thus, the electronic device determines the anti-interference noise value of the user terminal B at the other service carrier.
