Background
At present, in order to improve the service sensing rate of the terminal device, an operator generally uses an inter-frequency handover method.

In practical applications, the computing device 103 may be an entity server of the communication carrier, and may also be a virtual server of the communication carrier, such as a cloud server.
In addition, the communication system described in the embodiment of the present application is for more clearly illustrating the technical solution of the embodiment of the present application, and does not constitute a limitation to the technical solution provided in the embodiment of the present application, and it is known by a person of ordinary skill in the art that the technical solution provided in the embodiment of the present application is also applicable to similar technical problems with the evolution of network architecture and the appearance of new communication systems.
At present, the fifth generation mobile communication technology (5th generation mobile communication technology, 5G) is divided into two systems, i.e., TDD network and FDD network. The FDD network adopts two different frequency bands which are respectively used for an uplink from the terminal equipment to the access network equipment and a downlink from the access network equipment to the terminal equipment; TDD networks use the same frequency band for uplink and downlink transmissions.
Generally, a TDD network belongs to a medium-high frequency band, and compared with a low frequency band (e.g., 1.8 Gigahertz (GHZ) and 900 Megahertz (MHZ)) of the fourth generation mobile communication technology (4G), the coverage capability of the TDD network is insufficient, mainly due to insufficient uplink capability. When the access network device transmits data (i.e. downlink transmission) to the terminal device, the access network device has higher transmission power, so that the data transmission distance is longer, and the downlink coverage area is further expanded. However, when the terminal device transmits data (i.e., uplink transmission) to the access network device, the antenna power of the terminal device is low, which results in a short distance for data transmission, thereby reducing the uplink coverage.
At present, through cross-frequency band cooperation between a TDD network and an FDD network, the downlink coverage advantage of the TDD network and the uplink coverage advantage of the FDD network are fully exerted, so that the service perception rate of the terminal device is increased.
However, the conventional inter-band handover threshold is determined by the broadcast channel fixed level value, but RSRP does not reflect the voice quality and traffic perception of the terminal device. The frequency band determined in the traditional pilot frequency switching has low adaptability to the voice quality and the service perception of the terminal equipment, so that the terminal equipment cannot be switched to the frequency band with better voice quality and service perception, and the service experience of the terminal equipment is poor.
Exemplarily, as shown in fig. 2, in the 5G network, the inter-frequency handover between the existing TDD network and the existing FDD network is based on a fixed downlink RSRP manner. Fig. 2 shows uplink and downlink coverage of the 3.5G band, and uplink and downlink coverage of the 900M band. When the terminal device moves to the position of the uplink switching point a1, the uplink RSRP of the terminal device on the 3.5G frequency band at this time is smaller than the first preset threshold, and the difference between the uplink RSRP of the terminal device on the 3.5G frequency band and the uplink RSRP of the terminal device on the 900M frequency band at this time is larger than the second preset threshold, in this case, the terminal device may perform uplink switching to the 900M frequency band. When the terminal device moves to the position of the uplink switching point a2, the downlink RSRP of the terminal device on the 3.5G frequency band at this time is smaller than the third preset threshold, and the difference between the downlink RSRP of the terminal device on the 3.5G frequency band and the downlink RSRP of the terminal device on the 900M frequency band at this time is larger than the fourth preset threshold, in this case, the terminal device may perform downlink switching to the 900M frequency band. As can be seen from the above, the existing uplink and downlink decoupling technology allows the uplink and the downlink to set the handover threshold respectively. The switching threshold value in the prior art is a fixed value of RSRP, so that the switching threshold value can ensure that the terminal device is always connected with the access network device with higher RSRP in the moving process, thereby avoiding call drop caused by poor RSRP and ensuring service continuity of the terminal device. However, RSRP cannot reflect the voice quality and service awareness of the terminal device, which results in that the frequency band determined in the existing inter-frequency handover has low adaptability to the voice quality and service awareness of the terminal device, and the terminal device cannot be handed over to a frequency band with better voice quality and service awareness, which results in poor service experience of the terminal device.
In order to solve the problems in the prior art, an embodiment of the present application provides a pilot frequency switching method, which can ensure that a terminal device after pilot frequency switching has better service experience. As shown in fig. 3, the method includes:
s301, the computing device determines parameters corresponding to at least one frequency band in the target time period.
The parameters corresponding to the frequency band include the voice quality and/or the uplink and downlink service rate of the terminal device on the frequency band.
In one example, the speech quality is a mean opinion score/subjective mean score (MOS) score. The uplink service rate is the uplink rate of the terminal device. The downlink service rate is a terminal downlink rate of the terminal device.
Optionally, at least one frequency band may be of the same network system or of different network systems, and this embodiment of the present application is not particularly limited. Illustratively, the at least one frequency band includes a first frequency band and a second frequency band, the first frequency band is 3.5GHZ, the second frequency band is 900MHZ, wherein a network system of the first frequency band may be a TDD network in a 5G network, and a network system of the second frequency band may be an FDD network in the 5G network. Examples in the subsequent steps are the same as those herein, unless otherwise specified.
It should be noted that the target time period may be set by the computing device according to an actual situation, and this is not specifically limited in this embodiment of the application.
S302, the computing device determines a target frequency band in the target time period according to the parameter corresponding to at least one frequency band in the target time period.
The target frequency band is a frequency band with optimal voice quality and/or uplink and downlink service rate in at least one frequency band.
As a possible implementation manner, the specific implementation process of S302 may be: the computing equipment determines the service type of the terminal equipment, and determines a corresponding index from the parameters corresponding to at least one frequency band according to the service type of the terminal equipment. And the computing equipment compares the indexes in the parameters corresponding to the at least one frequency band in the target time period, and determines the frequency band corresponding to the parameter with higher index in the at least one frequency band as the target frequency band in the target time period.
In one example, the at least one frequency band includes a first frequency band and a second frequency band. If the first frequency band and the second frequency band are represented by preset numbers (for example, the first frequency band is represented by 1, and the second frequency band is represented by 0), the target frequency band is also represented by the preset numbers (for example, the target frequency band is 1, or the target frequency band is 0).
S303, the computing device determines whether the target frequency band in the target time period is different from the current frequency band of the terminal device.
It should be noted that the target time period may be set by the computing device according to actual conditions, for example, the computing device sets the target time period to a minimum time period that can avoid frequent switching of the terminal device. The above is merely an example of the target time period, and the computing device may set the target time period to other values, which is not limited in this application.
If the target frequency band in the target time period is different from the current frequency band of the terminal device, the computing device executes S304.
S304, the computing device indicates the terminal device to switch to the target frequency band.
It can be understood that, if the target frequency band is different from the current frequency band of the terminal device, it may indicate that the voice quality and/or the uplink and downlink service rate of the terminal device on the current frequency band are poor, and the voice quality and/or the uplink and downlink service rate of the terminal device on the target frequency band are good. And in the target time period, the voice quality and/or the uplink and downlink service rate of the target frequency band are superior to those of the current frequency band. Therefore, under the condition, the computing device instructs the terminal device to switch to the target frequency band, so that on the basis that the terminal device switched to the target frequency band can obtain better voice service experience and data service experience, frequent switching can be avoided, and the use experience of the terminal device is improved.
If the target frequency band in the target time period is the same as the current frequency band of the terminal device, the computing device executes S305.
S305, the computing device does not indicate the terminal device to switch to the target frequency band.
Optionally, the computing device may periodically execute the above S301 to S305, so that the switching indication determined by the computing device may change according to the network index of the terminal device and the change of the network environment, thereby improving the voice service experience and the service experience of the terminal device in different time periods.
It should be noted that, if the target time period is less than or equal to one cycle time period, the computing device may perform inter-frequency handover by using the method shown in fig. 3. If the target time period is greater than one cycle time period, the computing device needs to determine at least one cycle time period corresponding to the target time period, and then determine the target frequency band in each cycle time period of the at least one cycle time period by using the method shown in fig. 3. In this case, if the target frequency band in the at least one period time period is consistent and the target frequency band is different from the current frequency band, the computing device instructs the terminal device to switch to the target frequency band. If the target frequency band in the at least one periodic time period includes at least two different frequency bands, it indicates that there is no frequency band with a better index persistence in the network, and in this case, the computing device does not instruct the terminal device to switch to the target frequency band.
The technical scheme at least has the following beneficial effects: according to the pilot frequency switching method, the computing device firstly determines the voice quality and/or the uplink and downlink service rate on at least one frequency band, and determines a target frequency band with better voice quality and/or service rate according to the parameters. And under the condition that the target frequency band in the target time period is different from the current frequency band of the terminal equipment, the computing equipment indicates the terminal equipment to switch to the target frequency band. Therefore, according to the technical scheme, the target frequency band can be determined based on the voice quality and/or the service perception rate of the frequency band where the terminal is located, and the terminal device is indicated to switch to the target frequency band under the condition that the target frequency band is different from the current frequency band of the terminal device, so that the terminal device switched to the target frequency band can obtain better voice service experience and data service experience, and the service experience of the terminal device is guaranteed.
In an optional embodiment, as shown in S301, the computing device needs to determine a parameter corresponding to at least one frequency band in the target time period in advance, so that the subsequent computing device determines the target frequency band in the target time period according to the parameter corresponding to the at least one frequency band in the target time period. Therefore, this embodiment provides a possible specific implementation manner on the basis of the method embodiment shown in fig. 3, and with reference to fig. 3 and as shown in fig. 4, a specific implementation process of determining, by a computing device, a parameter corresponding to at least one frequency band in a target time period may be determined through the following steps S401 to S402.
S401, the computing device obtains indexes corresponding to at least one frequency band in the target time period.
The index corresponding to the frequency band is index information of the terminal device on the frequency band, and the index information includes: at least one of background noise, the number of RRC connection users, uplink and downlink cache, uplink and downlink RSRP, uplink and downlink SINR, uplink and downlink CQI, uplink and downlink PRB utilization rate, total downlink PRB number and uplink and downlink QCI.
As an optional implementation manner, the computing device may obtain the index from a network management system. The number of the bottom noise and the number of the RRC connected users are indexes of an access network device side in the network management system (namely, indexes of a cell side), uplink and downlink buffers, uplink and downlink RSRP, uplink and downlink SINR, uplink and downlink CQI, uplink and downlink PRB utilization rate, and total downlink PRB number, and the uplink and downlink QCI is an index of a terminal device side in the network management system (namely, an index of a user side).
It should be noted that, if the network system of the frequency band is an FDD network, the noise floor includes: uplink background noise and downlink background noise.
S402, the computing equipment determines a parameter corresponding to at least one frequency band in the target time period according to the index corresponding to the at least one frequency band in the target time period.
As an optional implementation manner, the specific implementation process of S402 includes: the computing device may input the index information corresponding to the frequency band in the target time period into the user experience model corresponding to the frequency band, so as to obtain a parameter corresponding to the frequency band in the target time period. The computing device may perform the above operation on the index corresponding to each of the at least one frequency band to obtain a parameter corresponding to the at least one frequency band. The technical scheme at least has the following beneficial effects: according to the pilot frequency switching method, the computing device obtains the index corresponding to at least one frequency band, and then determines the parameter corresponding to the at least one frequency band according to the index corresponding to the at least one frequency band. Therefore, according to the technical scheme, the parameters corresponding to at least one frequency band subsequently used for determining the target frequency band can be determined based on various indexes (such as indexes of bandwidth, load, interference and the like) of the frequency band where the terminal is located, and data preparation is provided for switching the terminal equipment to a better frequency band subsequently during pilot frequency switching.
In an optional embodiment, as shown in S402, the computing device needs to determine a parameter corresponding to at least one frequency band in the target time period according to an index corresponding to at least one frequency band in the target time period, so that the subsequent computing device determines the target frequency band in the target time period according to the parameter corresponding to at least one frequency band in the target time period. Therefore, this embodiment provides a possible specific implementation manner on the basis of the method embodiment shown in fig. 4, and with reference to fig. 4 and as shown in fig. 5, a specific implementation process of determining, by a computing device, a parameter corresponding to at least one frequency band in a target time period according to an index corresponding to at least one frequency band in the target time period may be determined through S501 below.
S501, inputting the index corresponding to the target frequency band in the target time period into the user experience model corresponding to the target frequency band by the computing equipment to obtain the parameter corresponding to the target frequency band in the target time period.
The target frequency band is any one of at least one frequency band.
It should be noted that the user experience models corresponding to different frequency bands may be different, and the user experience models corresponding to different frequency bands may be the same. As an example, the at least one frequency band includes a first frequency band and a second frequency band.
Example 1, the first frequency band corresponds to a first user experience model, and the second frequency band corresponds to a second user experience model.
In the case shown in example 1, the computing device may input the index corresponding to the first frequency band in the target time period into the first user experience model, so as to obtain the parameter corresponding to the first frequency band in the target time period. The computing device may input the index corresponding to the second frequency band in the target time period into the second user experience model, to obtain a parameter corresponding to the second frequency band in the target time period.
Example 2, the first frequency band and the second frequency band both correspond to a third user experience model.
In the case shown in example 2, the computing device may input the index corresponding to the first frequency band and the index corresponding to the second frequency band in the target time period into the third user experience model, so as to obtain the parameter corresponding to the first frequency band and the parameter corresponding to the second frequency band in the target time period.
In a possible implementation manner, the computing device obtains a plurality of sample data from a network system through the access network device, inputs the sample data into the initial neural network model for training for a plurality of times until a test result of the initial neural network model meets a preset condition, and determines that the initial neural network model is the user experience model. Exemplarily, the sample data may include: voice quality and/or uplink and downlink traffic rates on the target frequency band. Specifically, with reference to the foregoing example in S401, when the network standard of the target frequency band is a TDD network in a 5G network and the frequency is 3.5GHZ, the sample data may include: the method comprises the following steps of bottom noise, the number of RRC connection users, uplink and downlink cache, uplink and downlink RSRP, uplink and downlink SINR, uplink and downlink CQI, uplink and downlink PRB utilization rate, total downlink PRB number and uplink and downlink QCI.
In one example, as shown in fig. 6, the at least one frequency band includes a first frequency band and a second frequency band, the first frequency band is 3.5GHZ, and the second frequency band is 900 MHZ. The calculation device needs to input the pre-acquired index at 3.5GHZ and the pre-acquired index at 900MHZ into the user experience model corresponding to 3.5GHZ and the user experience model corresponding to 900MHZ, respectively, to obtain the parameter at 3.5GHZ and the parameter at 900MHZ, so as to determine the target frequency band subsequently. Specifically, the parameters are combined with the description in the foregoing S301, for example, the parameters at 3.5GHZ may include: the voice quality and/or the uplink and downlink service rate of the terminal equipment on the 3.5 GHZ; as another example, parameters at 900MHz may include: the voice quality and/or the uplink and downlink traffic rate of the terminal equipment at 900 MHz.
The technical scheme at least brings the following beneficial effects: according to the pilot frequency switching method provided by the application, the index corresponding to the target frequency band (namely any frequency band in at least one frequency band) is input into the user experience model corresponding to the target frequency band by the computing equipment, and the parameter corresponding to the target frequency band is determined. Because the user experience model is obtained according to multiple times of training and testing, the accuracy of the output result of the user experience model is higher, so that the accuracy of the parameter corresponding to at least one frequency band is improved, and more accurate data preparation is provided for the follow-up switching of the terminal to a better frequency band during pilot frequency switching.
In an optional embodiment, as shown in S302, the computing device needs to determine a target frequency band in a target time period in advance according to a parameter corresponding to at least one frequency band in the target time period, so that a subsequent computing device determines a handover indication according to the target frequency band in the target time period and a current frequency band of the terminal device. Therefore, this embodiment provides a possible specific implementation manner on the basis of the method embodiment shown in fig. 3, and with reference to fig. 5 and as shown in fig. 7, a specific implementation process of determining, by a computing device, a target frequency band in a target time period according to a parameter corresponding to at least one frequency band in the target time period may be determined through the following steps S701 to S702.
S701, the computing device determines the service type of the terminal device.
Wherein the service type includes at least one of: voice traffic, uplink data traffic, and downlink data traffic.
In an alternative embodiment, the service types can be divided into the following three cases: case 1, the service type is voice service. Case 2, the service type is an uplink data service. Case 3, the service type is a downlink data service. In different situations, the computing device determines the target frequency band differently. The following description will be made for different cases.
Case 1, the service type is voice service.
In case 1, the computing device performs S702.
S702, the computing device determines a frequency band with higher voice quality in at least one frequency band as a target frequency band.
In one example, the at least one frequency band includes a first frequency band and a second frequency band. The first speech quality, i.e. the speech quality of the terminal device in the first frequency band, is 10 and the second speech quality, i.e. the speech quality of the terminal device in the second frequency band, is 15. In this case, the computing device determines the second frequency band as the target frequency band.
Case 2, the service type is an uplink data service.
In case 2, the computing device performs S703.
S703, the computing device determines that, in the at least one frequency band, a frequency band with a higher uplink service rate is a target frequency band.
In one example, the at least one frequency band includes a first frequency band and a second frequency band. The first uplink traffic rate (i.e., the uplink traffic rate of the terminal device on the first frequency band) is 8, and the second uplink traffic rate (i.e., the uplink traffic rate of the terminal device on the second frequency band) is 4. In this case, the computing device determines that the first frequency band is the target frequency band.
Case 3, the service type is a downlink data service.
In case 3, the computing device performs S704.
S704, the computing device determines that a frequency band with a higher downlink service rate in the at least one frequency band is a target frequency band.
In one example, the at least one frequency band includes a first frequency band and a second frequency band. The first downlink traffic rate (i.e. the downlink traffic rate of the terminal device in the first frequency band) is 10, and the second downlink traffic rate (i.e. the downlink traffic rate of the terminal device in the second frequency band) is 15. In this case, the computing device determines the second frequency band as the target frequency band.
Optionally, if the service of the terminal device includes multiple services (e.g., a voice service and a downlink data service), the computing device needs to determine the frequency band with higher voice quality (denoted as frequency band 1) and the frequency band with higher downlink service rate (denoted as frequency band 2). If the frequency band 1 is consistent with the frequency band 2, the computing device determines that the frequency band 1 (or the frequency band 2) is the target frequency band. If the frequency band 1 is inconsistent with the frequency band 2, the computing device determines that the service with higher service priority is the target service in the voice service and the downlink data service, and determines that the frequency band with higher parameter corresponding to the target service is the target frequency band, for example, if the service priority of the voice service is higher than the service priority of the downlink data service, the computing device determines that the frequency band 1 is the target frequency band; if the service priority of the downlink data service is higher than the service priority of the voice service, the computing device determines that the frequency band 2 is the target frequency band.
The technical scheme at least has the following beneficial effects: according to the pilot frequency switching method, the computing device determines the service type of the terminal device firstly, and then determines the target frequency band according to the index corresponding to the service type in the parameter corresponding to at least one frequency band, so that the target frequency band can be determined to be more suitable for the service requirement of the terminal device, and the service experience of the terminal device is improved.
