Description

Technical Field

[0001] The present application relates to the field of communications, and in particular to a frequency band switching method, device, electronic device and storage medium. Background Art

[0002] At present, in order to improve the service perception rate of end users, operators usually use the method of inter-frequency switching. Inter-frequency switching is to perform cross-band collaborative work between the time division duplexing (TDD) network and the frequency division duplexing (FDD) network. Inter-frequency switching can give full play to the downlink experience advantages of the TDD network and the uplink coverage advantages of the FDD network.

[0003] At present, traditional inter-frequency switching (switching between frequency bands of TDD network and FDD network) is performed based on a fixed level value of the broadcast channel (for example, reference signal receiving power (RSRP)), without considering factors such as bandwidth, load, and interference of the broadcast channel. Therefore, the frequency band determined in the traditional inter-frequency switching has low adaptability to the terminal, and the terminal cannot switch to a better frequency band, resulting in a poor service experience for the terminal user. Summary of the invention

[0007] Based on the above technical solution, the present application obtains the index information of the terminal in the first frequency band and the second frequency band, and inputs the index information into the trained neural network model to determine the first parameter and the second parameter used to characterize the voice quality and service rate of the terminal in the two frequency bands. After that, the frequency band switching device determines the service perception parameter that can reflect the quality of the user's service perception experience based on the first parameter and the second parameter, and finally determines the RSRP switching threshold based on the service perception parameter, so that the frequency band switching device instructs the terminal to switch between the first frequency band and the second frequency band according to the RSRP of the terminal and the RSRP switching threshold. Therefore, the technical solution of the present application can determine the RSRP threshold for the terminal to switch between frequency bands in real time based on the multi-faceted indicators of the frequency band where the terminal is located, give full play to the advantages of different frequency bands in uplink transmission and downlink transmission, and realize that the terminal switches to a better frequency band during heterogeneous frequency switching, thereby ensuring the service experience of the terminal user.

[0031] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0032] In this article, the character " / " generally indicates that the objects before and after are in an "or" relationship. For example, A / B can be understood as A or B.

[0033] The terms "first" and "second" in the specification and claims of this application are used to distinguish different objects rather than to describe a specific order of objects. For example, a first edge service node and a second edge service node are used to distinguish different edge service nodes rather than to describe a characteristic order of edge service nodes.

[0034] In addition, the terms "including" and "having" and any variations thereof mentioned in the description of the present application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device comprising a series of steps or units is not limited to the listed steps or units, but may optionally include other steps or units that are not listed, or may optionally include other steps or units that are inherent to these processes, methods, products or devices.

[0035] In addition, in the embodiments of the present application, words such as "exemplarily" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplarily" or "for example" in the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplarily" or "for example" is intended to present concepts in a specific way.

[0036] At present, the fifth generation mobile communication technology (5G) is divided into two standards: time division duplexing (TDD) network and frequency division duplexing (FDD) network. Among them, the FDD network uses two different frequency bands, one for the uplink from the terminal to the base station and the other for the downlink from the base station to the terminal; the TDD network uses the same frequency band for uplink and downlink transmission.

[0037] Generally, TDD networks belong to the medium and high frequency bands. Compared with the low frequency bands of the fourth generation mobile communication technology (4G), such as 1.8GHz and 900MHz, the coverage of TDD networks is insufficient, mainly due to insufficient uplink capacity. When the base station transmits downlink to the terminal, the base station has a higher transmission power, coupled with technologies such as beamforming, which can significantly improve the downlink coverage. However, during uplink transmission, the antenna power of the terminal is very low, so the signal propagation distance is naturally short, which limits the uplink coverage of the base station.

[0038] At present, through cross-band collaboration between TDD networks and FDD networks, the downlink experience advantages of TDD networks and the uplink coverage advantages of FDD networks can be fully utilized to improve the service perception rate of end users.

[0039] However, the traditional inter-band switching threshold is determined by a fixed level value of the broadcast channel. However, since the influence of factors such as the bandwidth, load, and interference of the broadcast channel is not taken into account, the frequency band determined in the traditional inter-frequency switching has low adaptability to the terminal and cannot enable the terminal to switch to a better frequency band, resulting in a poor service experience for the terminal user.

[0040] For example, Figure 1 As shown in the figure, in the 5G network, the inter-frequency switching between the existing TDD network and the FDD network is based on a fixed downlink RSRP method. Figure 1 The figure shows the situation where the TDD network and the FDD network are co-located. When the RSRP of the terminal is less than a certain threshold, the terminal switches from the TDD network to the FDD network. The current uplink and downlink decoupling technology allows the uplink and downlink to set the switching thresholds separately. However, the switching threshold in the prior art is a fixed value, which cannot automatically change according to the communication scenario and network load after setting, and cannot guarantee the user's service experience.

[0041] In order to solve the problem that the terminal cannot switch to a better frequency band in the current inter-frequency switching, the present application provides a frequency band switching method to enable the terminal to switch to a better frequency band during inter-frequency switching, thereby ensuring the service experience of the terminal user.

[0042] For example, Figure 2 , which is a schematic diagram of an application scenario of a frequency band switching method provided by the present application. This application scenario includes a terminal 21 and a base station 22.

[0043] Among them, the terminal 21 and the base station 22 can perform uplink and downlink transmission through the TDD network and the FDD network. In addition, when the RSRP of the terminal 21 is greater than or equal to the uplink switching threshold set in this application, the terminal will switch from the first frequency band to the second frequency band for uplink transmission; when the RSRP of the terminal 21 is less than or equal to the downlink switching threshold set in this application, the terminal will switch from the second frequency band to the first frequency band for downlink transmission.

[0044] The base station 22 can provide the indicator information of the terminal 21 in the TDD network and the FDD network. Exemplarily, the indicator information may include one or more of the following: the base station side noise floor parameter of the terminal 21 within a preset time length, the uplink physical resource block (PRB) utilization rate, the total uplink PRB number, the downlink PRB utilization rate, and the total downlink PRB number.

[0045] It should be noted that in the frequency band switching method provided in the present application, the execution subject is a frequency band switching device. The frequency band switching device can be an electronic device (such as a computer terminal, a server), a processor in an electronic device, a control module for frequency band switching in an electronic device, or a client for frequency band switching in an electronic device.

[0046] The following is an explanation of the process of the frequency band switching method provided by this embodiment.

[0047] For example, Figure 3 As shown, the present application provides a frequency band switching method, which specifically includes the following S301-S307:

[0048] S301. A frequency band switching apparatus obtains indicator information on a first frequency band and a second frequency band within a preset time period of a terminal.

[0049] The indicator information includes one or more of the following: base station side noise floor parameter, uplink PRB utilization, total uplink PRB number, downlink PRB utilization, total downlink PRB number. Exemplarily, the frequency band switching device can obtain the indicator information on the first frequency band and the second frequency band within a preset time length of the terminal through the base station.

[0050] Optionally, the first frequency band and the second frequency band may be of the same network standard or of different network standards, which is not specifically limited in the embodiment of the present application. For example, the frequency of the first frequency band is 3.5 GHz, and the frequency of the second frequency band is 900 MHz, wherein the network standard of the first frequency band may be a TDD network in a 5G network, and the network standard of the second frequency band may be an FDD network in a 5G network. Unless otherwise specified, the examples in the subsequent steps are the same as the examples here.

[0051] Optionally, the preset duration may be manually set in advance through a frequency band switching device, and the embodiment of the present application does not specifically limit this.

[0052] S302. The frequency band switching device inputs the indicator information of the terminal in the first frequency band into a first user experience model to determine a first parameter.

[0053] The first parameter is used to characterize the voice quality and service rate of the terminal in the first frequency band within a preset RSRP interval.

[0054] Optionally, the first parameter includes an average subjective opinion score (MOS) score, a terminal uplink rate, and a terminal downlink rate on a first frequency band when the terminal is within a preset duration and a preset RSRP interval. Accordingly, the voice quality of the terminal within the preset RSRP interval is reflected by the MOS score, and the service rate of the terminal within the preset RSRP interval is reflected by the terminal uplink rate and the terminal downlink rate.

[0055] Optionally, the first user experience model is a neural network model, which is constructed based on a related neural network model algorithm. For example, the first user experience model can be constructed and trained according to a gradient descent algorithm, and the trained first user experience model can be used to determine the first parameter in the embodiment of the present application.

[0056] In a possible implementation, the frequency band switching device obtains sample data for building and training the first user experience model through the base station. Exemplarily, the aforementioned sample data may include: voice service data and data service data of the first frequency band. Specifically, in combination with the example in the aforementioned S301, when the network standard of the first frequency band is a TDD network in a 5G network and the frequency is 3.5 GHz, the sample data may include: base station side background noise, uplink PRB utilization, total uplink PRB number, downlink PRB utilization, total downlink PRB number, user side RSRP.

[0057] It should be noted that the method in which the frequency band switching device constructs a first user experience model based on sample data based on a neural network model algorithm is a prior art in the art and will not be described in detail in this application.

[0058] In a possible implementation, the frequency band switching device sets the preset RSRP interval to -120dBm to -60dBm, and accordingly, the frequency band switching device obtains a first parameter of the terminal within the range of -120dBm to -60dBm within a preset time length. Exemplarily, the frequency band switching device determines an RSRP value at intervals of 1dBm within the range of -120dBm to -60dBm. For example, the frequency band switching device first determines an RSRP value of -120dBm, combines this RSRP value with the indicator information of the first frequency band obtained in S301, and determines the MOS score, terminal uplink rate, and terminal downlink rate of the terminal at this RSRP value through the first user experience model. Furthermore, the frequency band switching device obtains the MOS score, terminal uplink rate and terminal downlink rate of the terminal corresponding to all RSRP values ​​with an interval of 1dBm in the range of -120dBm to -60dBm (that is, integer values ​​between -120dBm and -60dBm, a total of 61) through the first user experience model, and determines it as the first parameter.

[0059] S303: The frequency band switching device inputs the indicator information of the terminal in the second frequency band into a second user experience model to determine a second parameter.

[0060] The second parameter is used to characterize the voice quality and service rate of the terminal in the second frequency band within a preset RSRP interval.

[0061] Optionally, the second parameter includes an average subjective opinion score (MOS) score, a terminal uplink rate, and a terminal downlink rate on the second frequency band when the terminal is within a preset duration and a preset RSRP interval. Accordingly, the voice quality of the terminal within the preset RSRP interval is reflected by the MOS score, and the service rate of the terminal within the preset RSRP interval is reflected by the terminal uplink rate and the terminal downlink rate.

[0062] Optionally, the second user experience model is a neural network model, which is constructed based on a related neural network model algorithm. For example, the second user experience model can be constructed and trained according to a gradient descent algorithm, and the trained second user experience model can be used to determine the second parameter in the embodiment of the present application.

[0063] In a possible implementation, the frequency band switching device obtains sample data for building and training the second user experience model through the base station. Exemplarily, the aforementioned sample data may include: voice service data and data service data of the second frequency band. Specifically, in combination with the example in the aforementioned S301, when the network standard of the second frequency band is the FDD network in the 5G network and the frequency is 900MHz, the sample data may include: base station side background noise, uplink PRB utilization, total uplink PRB number, downlink PRB utilization, total downlink PRB number, user side RSRP.

[0064] It should be noted that the method in which the frequency band switching device constructs a second user experience model based on sample data based on a neural network model algorithm is a prior art in the art and will not be described in detail in this application.

[0065] In a possible implementation, the frequency band switching device sets the preset RSRP interval to -120dBm to -60dBm, and accordingly, the frequency band switching device obtains the second parameter of the terminal within the preset time length within the range of -120dBm to -60dBm. Exemplarily, the frequency band switching device determines an RSRP value at every interval of 1dBm within the range of -120dBm to -60dBm. For example, the frequency band switching device first determines an RSRP value of -120dBm, combines this RSRP value with the indicator information of the second frequency band obtained in S301, and determines the MOS score, terminal uplink rate and terminal downlink rate of the terminal under this RSRP value through the second user experience model. Further, the frequency band switching device obtains the MOS score, terminal uplink rate and terminal downlink rate of the terminal corresponding to all RSRP values ​​(that is, integer values ​​between -120dBm and -60dBm, a total of 61) within the range of -120dBm to -60dBm, and determines it as the second parameter.

[0066] S304: The frequency band switching device determines a service perception parameter of the first frequency band according to the first parameter.

[0067] Optionally, the service perception parameter of the first frequency band includes a first uplink service perception parameter and a first downlink service perception parameter. It can be understood that the service perception parameter reflects the quality of the user's experience of the terminal after perceiving the service in a communication environment based on the first parameter. The higher the parameter value of the service perception parameter, the better the user's experience of the service is; conversely, the lower the parameter value of the service perception parameter, the worse the user's experience of the service is.

[0068] Optionally, a method for determining the first uplink service perception parameter and the first downlink service perception parameter is described below:

[0069] (1) The frequency band switching device determines a first uplink service perception parameter.

[0070] The frequency band switching device determines the first uplink service perception parameter according to the MOS score, the terminal uplink rate, the first weighting coefficient and the second weighting coefficient on the first frequency band when the terminal is located within the preset time length and the preset RSRP interval.

[0071] In a possible implementation manner, calculation of the first uplink service perception parameter satisfies the following formula 1:

[0072] First uplink service perception = α × terminal uplink rate + β × MOS score Formula 1

[0073] Wherein, α represents the first weighting coefficient, and β represents the second weighting coefficient. For example, the first weighting coefficient is 0.5, and the second weighting coefficient is 0.5. The specific values ​​of the first weighting coefficient and the second weighting coefficient may be determined according to the actual situation, and the embodiment of the present application does not make specific limitations.

[0074] Exemplarily, corresponding to the example in S302, the frequency band switching device determines the first uplink service perception based on the MOS score of the terminal and the terminal uplink rate corresponding to all RSRP values ​​of the terminal in the range of -120dBm to -60dBm with an interval of 1dBm (that is, integer values ​​between -120dBm and -60dBm, a total of 61) in the 3.5GHz frequency band (that is, the first frequency band), combined with formula 1.

[0075] (2) The frequency band switching device determines the first downlink service perception parameter.

[0076] The frequency band switching device determines the first downlink service perception parameter according to the MOS score, the terminal downlink rate, the first weighting coefficient and the second weighting coefficient on the first frequency band when the terminal is located within the preset time length and the preset RSRP interval.

[0077] In a possible implementation manner, calculation of the first uplink service perception parameter satisfies the following formula 2:

[0078] First downlink service perception = α × terminal downlink rate + β × MOS score Formula 2

[0079] Wherein, α represents the first weighting coefficient, and β represents the second weighting coefficient. For example, the first weighting coefficient is 0.5, and the second weighting coefficient is 0.5. The specific values ​​of the first weighting coefficient and the second weighting coefficient may be determined according to the actual situation, and the embodiment of the present application does not make specific limitations.

[0080] Exemplarily, corresponding to the example in S302, the frequency band switching device determines the first downlink service perception based on the MOS score of the terminal and the terminal downlink rate corresponding to all RSRP values ​​of the terminal in the range of -120dBm to -60dBm with an interval of 1dBm (that is, integer values ​​between -120dBm and -60dBm, a total of 61) in the 3.5GHz frequency band (that is, the first frequency band), combined with formula 1.

[0081] The method for determining the first uplink service perception parameter and the first downlink service perception parameter is described above.

[0082] S305. The frequency band switching device determines a service perception parameter of the second frequency band according to the second parameter.

[0083] Optionally, the service perception parameter of the second frequency band includes a second uplink service perception parameter and a second downlink service perception parameter. It can be understood that the service perception parameter reflects the quality of the user's experience of the terminal after perceiving the service in a communication environment based on the second parameter. The higher the parameter value of the service perception parameter, the better the user's experience of the service is; conversely, the lower the parameter value of the service perception parameter, the worse the user's experience of the service is.

[0084] Optionally, a method for determining the second uplink service perception parameter and the second downlink service perception parameter is described below:

[0085] (1) The frequency band switching device determines the second uplink service perception parameter.

[0086] The frequency band switching device determines the second uplink service perception parameter according to the MOS score, the terminal uplink rate, the second weighting coefficient and the second weighting coefficient on the second frequency band when the terminal is within the preset time length and the preset RSRP interval.

[0087] In a possible implementation manner, calculation of the second uplink service perception parameter satisfies the following formula 3:

[0088] Second uplink service perception = α × terminal uplink rate + β × MOS score Formula 3

[0089] Wherein, α represents the second weighting coefficient, and β represents the second weighting coefficient. For example, the second weighting coefficient is 0.5, and the second weighting coefficient is 0.5. The specific second weighting coefficient and the value of the second weighting coefficient can be determined according to the actual situation, and the embodiment of the present application does not make specific limitations.

[0090] Exemplarily, corresponding to the example in S302, the frequency band switching device determines the second uplink service perception based on the MOS score of the terminal and the terminal uplink rate corresponding to all RSRP values ​​of the terminal in the range of -120dBm to -60dBm with an interval of 1dBm (that is, integer values ​​between -120dBm and -60dBm, a total of 61) in the 3.5GHz frequency band (that is, the second frequency band), combined with formula 1.

[0091] (2) The frequency band switching device determines the second downlink service perception parameter.

[0092] The frequency band switching device determines the second downlink service perception parameter according to the MOS score, the terminal downlink rate, the second weighting coefficient and the second weighting coefficient on the second frequency band when the terminal is located within the preset time length and the preset RSRP interval.

[0093] In a possible implementation manner, calculation of the second uplink service perception parameter satisfies the following formula 4:

[0094] Second downlink service perception = α × terminal downlink rate + β × MOS score Formula 4

[0095] Wherein, α represents the second weighting coefficient, and β represents the second weighting coefficient. For example, the second weighting coefficient is 0.5, and the second weighting coefficient is 0.5. The specific second weighting coefficient and the value of the second weighting coefficient can be determined according to the actual situation, and the embodiment of the present application does not make specific limitations.

[0096] Exemplarily, corresponding to the example in S302, the frequency band switching device determines the second downlink service perception based on the MOS score of the terminal and the terminal downlink rate corresponding to all RSRP values ​​of the terminal in the range of -120dBm to -60dBm with an interval of 1dBm (that is, integer values ​​between -120dBm and -60dBm, a total of 61) in the 3.5GHz frequency band (that is, the second frequency band), combined with formula 1.

[0097] The method for determining the second uplink service perception parameter and the second downlink service perception parameter is described above.

[0098] S306: The frequency band switching apparatus determines an RSRP switching threshold of the terminal between the first frequency band and the second frequency band according to the service perception parameters of the first frequency band and the second frequency band.

[0099] Optionally, the RSRP switching threshold includes an uplink switching threshold and a downlink switching threshold, which are respectively applied to frequency band switching of the terminal during uplink transmission and downlink transmission.

[0100] In one possible implementation, Figure 4 As shown, the frequency band switching device establishes a two-dimensional rectangular coordinate system, the horizontal coordinate of which is RSRP. The vertical coordinate is the service perception parameter. Further, the frequency band switching device determines the fitting curves corresponding to the first uplink service perception parameter, the first downlink service perception parameter, the second uplink service perception parameter, and the second downlink service perception parameter in the coordinate system.

[0101] After that, the frequency band switching device determines the horizontal coordinate of the intersection of the fitting curve corresponding to the first uplink service perception parameter and the second uplink service perception parameter as the uplink switching threshold; the frequency band switching device determines the horizontal coordinate of the intersection of the fitting curve corresponding to the first downlink service perception parameter and the second downlink service perception parameter as the downlink switching threshold.

[0102] For example, in Figure 4 In the figure, curve 1 and curve 2 represent the fitting curves corresponding to the first uplink service perception parameter and the second uplink service perception parameter, respectively. Curve 1 and curve 2 intersect at point a, and the horizontal coordinate x of point a is a The corresponding RSRP value is the uplink switching threshold.

[0103] For example, similarly, in Figure 4 In the figure, curve 3 and curve 4 represent the fitting curves corresponding to the first downlink service perception parameter and the second downlink service perception parameter, respectively. Curve 3 and curve 4 intersect at point b. The horizontal coordinate x of point b is b The corresponding RSRP value is the uplink switching threshold.

[0104] S307: The frequency band switching apparatus instructs the terminal to switch between the first frequency band and the second frequency band according to the RSRP of the terminal and the RSRP switching threshold.

[0105] It should be noted that, combined with the examples in the previous steps, due to the characteristics of TDD and FDD networks, when RSRP is low, uplink transmission uses the 3.5GHz frequency band (i.e., the first frequency band) corresponding to the TDD network; when RSRP is high, downlink transmission uses the 900MHz frequency band (i.e., the second frequency band) corresponding to the FDD network. It is not difficult to see that this is also related to Figure 4 The situation shown is consistent.

[0106] The following specifically describes the process of the frequency band switching device instructing the terminal to switch between the first frequency band and the second frequency band according to the RSRP of the terminal and the RSRP switching threshold according to different situations:

[0107] Case 1: The RSRP of the terminal is greater than the uplink switching threshold.

[0108] This is aimed at the uplink transmission of the terminal, combined with Figure 4 , it can be seen that if the terminal switches to the second frequency band, the corresponding service perception parameter will be higher, that is, the service perception experience of the terminal user after switching will be better. Therefore, the frequency band switching device instructs the terminal to switch from the first frequency band to the second frequency band for uplink transmission at this time.

[0109] Case 2: The RSRP of the terminal is less than or equal to the uplink switching threshold.

[0110] This is aimed at the uplink transmission of the terminal, combined with Figure 4 It can be seen that even after the terminal switches to the second frequency band, the corresponding service perception parameters will remain unchanged or decrease, that is, the service perception experience of the terminal user after switching will be worse. Therefore, the frequency band switching device instructs the terminal not to switch the frequency band at this time and continue to maintain uplink transmission in the first frequency band.

[0111] Case 3: The terminal RSRP is less than the downlink switching threshold.

[0112] This is aimed at the downlink transmission of the terminal, combined with Figure 4, it can be seen that if the terminal switches to the first frequency band, the corresponding service perception parameter will be higher, that is, the service perception experience of the terminal user after switching will be better. Therefore, the frequency band switching device instructs the terminal to switch from the second frequency band to the first frequency band for downlink transmission at this time.

[0113] Case 4: The terminal RSRP is greater than or equal to the downlink switching threshold.

[0114] This is aimed at the downlink transmission of the terminal, combined with Figure 4 It can be seen that even after the terminal switches to the first frequency band, the corresponding service perception parameters will remain unchanged or decrease, that is, the service perception experience of the terminal user after switching will be worse. Therefore, the frequency band switching device instructs the terminal not to switch the frequency band at this time and continue to maintain the downlink transmission in the second frequency band.

[0115] Understandably, reference Figure 4 It can be seen that when the RSRP of the terminal is within the uplink switching threshold (i.e. Figure 4 The horizontal coordinate x of point a in a ) to (i.e. Figure 4 The horizontal coordinate x of point b in b ), according to the switching process of the present application, the terminal uses the second frequency band for uplink transmission at this time, and the first frequency band for downlink transmission. Exemplarily, in combination with the example of the above steps, at this time, the terminal uses 900MHz corresponding to the FDD network for uplink transmission, and 3.5GHz corresponding to the TDD network for downlink transmission.

[0116] Therefore, the present application can fully utilize the advantages of different frequency bands in uplink and downlink transmission through cross-frequency band collaboration between the first frequency band and the second frequency band, thereby improving the service experience of terminal users.

[0117] The above specifically describes the process of the frequency band switching apparatus instructing the terminal to switch between the first frequency band and the second frequency band according to the RSRP of the terminal and the RSRP switching threshold according to different situations.

[0118] Based on the above technical solution, the frequency band switching device in the embodiment of the present application obtains the index information of the terminal in the first frequency band and the second frequency band, and inputs these index information into the trained neural network model to determine the first parameter and the second parameter used to characterize the voice quality and service rate of the terminal in the two frequency bands. After that, the frequency band switching device determines the service perception parameter that can reflect the quality of the user's service perception experience based on the first parameter and the second parameter, and finally determines the RSRP switching threshold based on the service perception parameter, so that the frequency band switching device instructs the terminal to switch between the first frequency band and the second frequency band according to the RSRP of the terminal and the RSRP switching threshold. Therefore, the technical solution of the present application can determine the RSRP threshold for the terminal to switch between frequency bands in real time based on the multi-faceted indicators of the frequency band where the terminal is located, give full play to the advantages of different frequency bands in uplink transmission and downlink transmission, and realize that the terminal switches to a better frequency band when switching between different frequencies, thereby ensuring the service experience of the terminal user.
