[0029] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

It should be understood that the terms used in this way are interchangeable where appropriate, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited.

In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.
[0031] The cell access method, apparatus, device and medium provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings through specific embodiments and their application scenarios.
[0032] Figure 1 : is a flowchart of a cell access method provided in an embodiment of the present application. The cell access method may include:
[0033] Step 101: Obtain frequency band information, channel information, and reference signal received power of at least two first cells;
[0034] In some possible implementations of the embodiments of the present application, when performing cell selection (eg, cell reselection or cell switching), the electronic device obtains frequency band information, channel information, and reference signal received power of at least two first cells.
[0035] In some possible implementations of the embodiment of the present application, before step 101, the cell access method provided in the embodiment of the present application may further include: determining a cell that satisfies a first condition among the at least two second cells as the first cell; the first condition includes:
[0036] The signal strength corresponding to the cell is greater than a first threshold;
[0037] The signal quality corresponding to the cell is greater than a second threshold;
[0038] The operator corresponding to the cell is the same as the operator of the Subscriber Identity Module (SIM) card of the electronic device.
[0039] In some possible implementations of the embodiments of the present application, the first threshold and the second threshold can be set according to actual needs.
[0040] When the signal strength corresponding to the cell is greater than the first threshold, it means that the signal strength of the cell is strong; when the signal quality corresponding to the cell is greater than the second threshold, it means that the signal quality of the cell is good; when the operator corresponding to the cell is the same as the operator of the user identity card of the electronic device, it means that the SIM card of the cell and the electronic device are provided by the same operator.
[0041] In an embodiment of the present application, when the cell signal strength is strong, the cell signal quality is good, and the cell and the SIM card of the electronic device are provided by the same operator, the cell is used as an alternative cell when the electronic device accesses, which can prevent the electronic device from accessing a cell with poor signal strength or a cell with poor signal quality or a cell provided by other operators, thereby ensuring the communication effect of the electronic device.
[0042] In some possible implementations of the embodiments of the present application, a cell selection reception level value Srxlev is usually used to measure the cell signal strength, and a cell selection signal quality value Squal is used to measure the cell signal quality.
[0043] In some possible implementations of the embodiments of the present application, the cell selection reception level value may be calculated according to the following formula (1):
[0044] Srxlev=Qrxlevmeas-(qRxLevMin+qRxLevMinOffset)-pCompensation (1)
[0045] Wherein, in formula (1), Srxlev is the cell selection reception level value, Qrxlevmeas is the reference signal reception power of the cell, qRxLevMin is the minimum reception level of the cell, qRxLevMinOffset is the minimum reception level offset of the cell, pCompensation is the compensation power, pCompensation = max(pMax-puMax), pMax is the maximum uplink transmission power allowed by the cell for the electronic device, and puMax is the maximum uplink transmission power supported by the electronic device capability.
[0046] In some possible implementations of the embodiments of the present application, the cell selection signal quality value may be calculated according to the following formula (2):
[0047] Squal=Qqualmeas-(qQualMin+qQualMinOffset) (2)
[0048] In formula (2), Squal is the cell selection signal quality value, Qqualmeas is the reference signal reception quality of the cell, qQualMin is the minimum reception signal quality of the cell, and qQualMinOffset is the minimum reception signal quality offset of the cell.
[0049] Step 102: determining a first radio frequency power consumption of an electronic device corresponding to the first target cell according to the frequency band information and channel information of the first target cell and a preset correspondence relationship between the frequency band, channel and power consumption, wherein the first target cell is any one of the at least two first cells;
[0050] In some possible implementations of the embodiments of the present application, before step 101, the cell access method provided by the embodiments of the present application may also include: obtaining a first DC power consumption when the electronic device transmits a signal of first power on a first channel in a first frequency band; wherein the first frequency band is any one of multiple frequency bands, and the first channel is any one of multiple channels of the first frequency band; obtaining a second DC power consumption when the electronic device transmits a signal of second power on the first channel; determining the RF power consumption corresponding to the electronic device on the first channel based on the first DC power consumption and the second DC power consumption; and establishing a corresponding relationship between the RF power consumption, the first frequency band, and the first channel.
[0051] In some possible implementations of the embodiments of the present application, a correspondence between frequency bands, channels, and power consumption may be established before the electronic device leaves the factory. After the correspondence is established, the correspondence is configured in the electronic device.
[0052] In some possible implementations of the embodiments of the present application, the first power and the second power may be set according to actual needs. The second power may be the minimum transmit power of the electronic device. Since the radio frequency power consumption of the electronic device will only significantly affect the power consumption of the communication system of the electronic device in a high-power scenario, the first power may take the maximum transmit power typical value specified in the 3GPP protocol.
[0053] In some possible implementations of the embodiments of the present application, in different frequency bands, the RF front end of the electronic device usually calls different hardware paths. Due to device insertion loss, RF power amplifier matching, frequency characteristics of the power amplifier, etc., the RF power consumption of the electronic device is different. Therefore, it is necessary to test and record the RF power consumption of the electronic device in each frequency band.
[0054] In some possible implementations of the embodiments of the present application, in order to reduce the amount of test data, frequency sampling can be performed from the frequency band to test the radio frequency power of the electronic device at each sampling frequency.
[0055] In some possible implementations of the embodiments of the present application, the frequency band may be divided into several channels, and the central frequency band of each channel may be used as a sampling point.
[0056] In some possible implementations of the embodiments of the present application, for a certain frequency point, the DC power consumption corresponding to the signal with the first power transmitted at the frequency point and the DC power consumption corresponding to the signal with the second power transmitted at the frequency point can be tested, and the RF power consumption of the electronic device at the frequency point can be calculated based on the two DC power consumptions.
[0057] In some possible implementations of the embodiments of the present application, for a frequency division duplex (FDD) frequency band, the radio frequency power consumption may be calculated according to the following formula (3):
[0058] P dBm =10*log 10 (P max -P min )(3)
[0059] In formula (3), P dBm is the RF power consumption, P max is the first DC power consumption corresponding to the signal transmitting the first power, P min The second DC power consumption corresponding to transmitting the signal with the second power.
[0060] In some possible implementations of the embodiments of the present application, for a time division duplexing (TDD) frequency band, the radio frequency power consumption may be calculated according to the following formula (4):
[0061] P dBm =10*log 10 [(P max -P min ) / D] (4)
[0062] In formula (4), P dBm is the RF power consumption, P max is the first DC power consumption corresponding to the signal transmitting the first power, P min is the second DC power consumption corresponding to transmitting the signal with the second power, and D is the transmission duty cycle when testing the power consumption in the TDD frequency band.
[0063] In some possible implementations of the embodiments of the present application, after calculating the RF power of the center frequency of a channel in a certain frequency band, a correspondence between the frequency band, the center frequency of the channel and the RF power consumption can be established. It can be understood that the correspondence between the frequency band, the center frequency of the channel and the RF power consumption is the correspondence between the frequency band, the channel and the RF power consumption.
[0064] Exemplarily, the correspondence between the frequency band, the center frequency of the channel and the RF power consumption is shown in Table 1 below.
[0065] Table 1
[0066] Frequency 1 Frequency 2 …… Frequency n Band 1 PdBm11 PdBm12 …… PdBm1 Band 2 PdBm21 PdBm22 …… PdBm2 Band 3 PdBm31 PdBm32 …… PdBm3 …… …… …… …… …… Frequency band m PdBmm1 PdBmm2 …… PdB
[0067] The frequencies of the center frequency points of the channels in each frequency band are shown in Table 2 below.
[0068] Table 2
[0069] Frequency 1 Frequency 2 …… Frequency n Band 1 1930MHz 1940MHz …… …… Band 2 1865MHz 1880MHz …… …… Band 3 1725MHz 1740MHz …… …… …… …… …… …… …… Frequency band m …… …… …… ……
[0070] Assume that the frequency band of the cell is band 3 and the channel is channel number 1400, wherein the channel number 1400 is hereinafter referred to as channel 1400; the frequency of channel 1400 of band 3 is 1730 MHz, and 1730 MHz is close to 1725 MHz. Therefore, according to Table 2, it can be determined that the frequency point corresponding to channel 1400 of band 3 is frequency point 1 of band 3. Furthermore, according to Table 1, it can be determined that under channel 1400 of band 3, the RF power consumption of the electronic device is PdBm31.
[0071] In some possible implementations of the embodiments of the present application, after calculating the radio frequency power consumption of the electronic device at the center frequency of each channel in each frequency band, the radio frequency power consumption of the electronic device at each frequency point in each frequency band can also be obtained by curve fitting. The embodiments of the present application do not specify the method used for fitting power consumption, and any available method can be applied to the embodiments of the present application.
[0072] Step 103: determining a cell selection reception level value corresponding to the first target cell according to the reference signal reception power of the first target cell;
[0073] In some possible implementations of the embodiments of the present application, step 103 may include: determining the compensation power corresponding to the electronic device based on the maximum uplink transmit power allowed by the first target cell for the electronic device and the maximum uplink transmit power supported by the electronic device's capabilities; calculating the sum of the compensation power, the minimum receiving level of the first target cell, and the minimum receiving level offset corresponding to the first target cell to obtain the first receiving power; calculating the difference between the reference signal receiving power and the first receiving power to obtain the cell selection receiving level value.
[0074] In some possible implementations of the embodiments of the present application, the cell selection reception level value of the first target cell may be calculated with reference to the above (1).
[0075] Step 104: determining a cell selection criterion corresponding to the first target cell according to the first radio frequency power consumption and the cell selection reception level value;
[0076] In some possible implementations of the embodiments of the present application, the cell selection criterion is used to characterize the relative relationship between the radio frequency power consumption of the electronic device when accessing different cells.
[0077] In some possible implementations of the embodiment of the present application, step 104 may include: determining the difference between the cell selection reception level value and the first radio frequency power consumption as a cell selection criterion corresponding to the first target cell.
[0078] Specifically, the cell selection criterion corresponding to the first target cell may be calculated according to the following formula (5):
[0079] C=Srxlev-P dBm (5)
[0080] Wherein, in formula (5), C is the cell selection criterion corresponding to the first target cell, Srxlev is the cell selection reception level value corresponding to the first target cell, P dBm is the radio frequency power consumption of the electronic device; Srxlev is used to characterize the signal size received by the electronic device in the first target cell and is used to determine the power size required for uplink transmission of the electronic device, P dBm It is used to characterize the size of the RF power consumption in the corresponding frequency band and channel, which takes into account the power consumption level of the electronic device's own hardware.
[0081] Step 105: Determine the first cell corresponding to the maximum cell selection criterion among the at least two first cells as the cell that the electronic device needs to access.
[0082] Exemplarily, assuming there are two cells, namely cell A and cell B, and the cell selection criterion of cell B is greater than the cell selection criterion of cell A, cell B is determined as the cell that the electronic device needs to access, and then the electronic device accesses cell B.
[0083] Generally speaking, the greater the reference signal receiving power of a cell, the greater the signal strength of the cell, and the better the signal representing the cell. The closer the electronic equipment is to the cell, the lower the RF power of the signal transmitted by the electronic equipment. The power consumption difference caused by the frequency band and channel can be compensated by combining the hardware power consumption of the electronic equipment to achieve the cell selection with the optimal power consumption.
[0084] It should be noted that the greater the cell selection criterion, the lower the power consumption when the electronic device accesses the cell.
[0085] In an embodiment of the present application, by acquiring the frequency band information, channel information and reference signal receiving power of at least two first cells; determining the first radio frequency power consumption of the electronic device corresponding to the first target cell according to the frequency band information and channel information of the first target cell and the correspondence between the pre-set frequency band, channel and power consumption, wherein the first target cell is any one of the at least two first cells; determining the cell selection receiving level value corresponding to the first target cell according to the reference signal receiving power of the first target cell; determining the cell selection criterion corresponding to the first target cell according to the first radio frequency power consumption and the cell selection receiving level value; determining the first cell corresponding to the maximum cell selection criterion among the at least two first cells as the cell that the electronic device needs to access. In this way, through the scheme disclosed in the present application, the radio frequency power consumption of the electronic device is taken into account when accessing the cell, and the electronic device accesses the cell determined by the radio frequency power consumption, which can reduce the power consumption of the electronic device.
[0086] Figure 2 : is a schematic diagram of the process of establishing the correspondence between RF power consumption, frequency band and channel provided by an embodiment of the present application. The process of establishing the correspondence between RF power consumption, frequency band and channel includes the following steps:
[0087] Step 201: Before the electronic mobile phone leaves the factory, the electronic device is tested for a first DC power consumption corresponding to a signal of a first power transmitted at each sampling frequency point in each frequency band and a second DC power consumption corresponding to a signal of a second power transmitted;
[0088] Step 202: Calculate the radio frequency power consumption of the electronic device corresponding to each sampling frequency point in each frequency band according to the first DC power consumption and the second DC power consumption;
[0089] Step 203: Establish a correspondence between the frequency band, the center frequency of the channel and the radio frequency power consumption.

[0091] Step 204: when performing cell access, determining a cell that satisfies the first condition among the at least two second cells as the first cell;
[0092] Step 205: Obtain frequency band information, channel information, and reference signal received power of at least two first cells;
[0093] Step 206: determining a first radio frequency power consumption of an electronic device corresponding to the first target cell according to the frequency band information and channel information of the first target cell and the correspondence between the frequency band, the channel and the radio frequency power consumption, wherein the first target cell is any first cell of the at least two first cells;
[0094] Step 207: determining a cell selection reception level value corresponding to the first target cell according to the reference signal reception power of the first target cell;
[0095] Step 208: Determine the difference between the cell selection reception level value and the first radio frequency power consumption as a cell selection criterion corresponding to the first target cell;
