Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a flowchart of a control method of a terminal device according to an embodiment of the present invention, where the control method of the terminal device is applied to the terminal device, and as shown in fig. 1, the method includes the following steps:
In this step, the terminal device obtains cell information of a first cell of the terminal device, where the first cell at least includes a serving cell of the terminal device. The cell information at least comprises the cell identification code, and further, the cell information can also comprise cell service quality.
And 102, predicting the network environment of the terminal equipment according to the cell information and a preset model.
In this step, the terminal device predicts a network environment of the terminal device according to the cell information and a preset model, where the preset model may be a preset AI (artificial intelligence) model. The terminal device may predict whether a target network satisfying a first preset condition exists in a network environment of the terminal device.
The target network meeting the first preset condition may be a network having a higher access priority than a current access network of the terminal device. Specifically, when the terminal device is a terminal device supporting a target network, but a network to which the terminal device is currently connected is a first network, where the first network is a generation network prior to the target network, the terminal device may predict whether the terminal device is about to enter an environment covered by the target network. For example, for a terminal device supporting a 4G (fourth generation mobile communication technology) network, when a network to which the terminal device is currently connected is a 2G (second generation mobile communication technology) or 3G (third generation mobile communication technology) network, the terminal device may predict whether the terminal device is about to enter an environment covered by the 4G network.
The target networks satisfying the first preset condition may include a first target network having a duration longer than a preset duration, for example, a 5G (fifth generation mobile communication technology) network having a duration longer than a preset duration. For example, when the terminal device supports a 5G network, the terminal device may predict whether the 5G network having a duration longer than a preset duration exists in a network environment of the terminal device.
In some embodiments of the present invention, before the step 102, the terminal device may further determine whether a serving cell of the terminal device is a preset cell, and execute the step 102 when the serving cell of the terminal device is the preset cell.
In this step, when there is no target network satisfying a first preset condition in the predicted network environment of the terminal device, the search for the target network is stopped. Specifically, when the target network satisfying the first preset condition is a network having a higher access priority than the network to which the terminal device currently accesses, for example, a 4G network, in the case that the predicted network environment of the terminal device does not include the 4G network, the terminal device stops searching for the 4G network, which can reduce power consumption of the terminal device.
When the target network meeting the first preset condition is a first target network with duration longer than the preset duration, for example, a 5G network with duration longer than the preset duration, and under the condition that the predicted network environment of the terminal device does not have the 5G network with duration longer than the preset duration, the terminal device stops searching for the 5G network, so that power consumption of the terminal device can be reduced. It is understood that, for a terminal device in which a 5G modem (modem) is independent of other network modems, the manner in which the terminal device stops searching for a 5G network may specifically include turning off the 5G modem of the terminal device.
In this embodiment of the present invention, the terminal device may be a mobile terminal device, for example: mobile phones, Tablet Personal computers (Tablet Personal computers), Laptop computers (Laptop computers), Personal Digital Assistants (PDAs), Mobile Internet Devices (MIDs) or Wearable devices (Wearable devices), digital cameras, and the like; but also fixed terminal equipment such as computers and the like.
In this embodiment, the control method of the terminal device obtains cell information of a first cell of the terminal device, where the first cell at least includes a serving cell of the terminal device; predicting the network environment of the terminal equipment according to the cell information and a preset model; and stopping searching the target network under the condition that the predicted network environment of the terminal equipment does not have the target network meeting the first preset condition. In this way, when the target network meeting the first preset condition does not exist in the predicted network environment, the target network is stopped to be searched, and the power consumption of the terminal equipment can be effectively reduced.
Optionally, before the obtaining the cell information of the first cell of the terminal device, the method further includes:
collecting multiple groups of training data of the terminal equipment, wherein each group of training data at least comprises cell information of a first cell of the terminal equipment and network service state information of the terminal equipment;
and importing the multiple groups of training data into a model for training to obtain the preset model.
In this embodiment, before obtaining the cell information of the first cell of the terminal device, the terminal device may collect data to train, so as to obtain the preset model. Specifically, the terminal device may collect a plurality of sets of training data of the terminal device, and then import the plurality of sets of training data into a model for training to obtain the preset model. Each set of training data at least includes cell information of a first cell of the terminal device and network service state information of the terminal device.
The terminal device may introduce the multiple sets of training data into an AI model for training, where the AI model may be an AI model in which training data have a timing relationship, such as LSTM (Long Short-Term Memory).
In some embodiments of the present invention, the accuracy of the preset model is greater than a preset accuracy, specifically, in the training process, the terminal device may evaluate the accuracy of the preset model, and if the accuracy of the preset model is greater than the preset accuracy, the preset model may be used for prediction; conversely, if the accuracy of the preset model is not greater than the preset accuracy, the training data may be continuously collected, and the collected training data may be introduced into the model for continuous training until the obtained preset model with the accuracy greater than the preset accuracy is obtained.
It can be understood that, because the change of the network deployment environment may affect the prediction result, in some embodiments of the present invention, the terminal device may estimate the false positive probability of the preset model after predicting the network environment of the terminal device, and in a case that the false positive probability of the preset model is greater than the preset false positive probability, recollect the training data, and introduce the collected training into the model for training again. Therefore, the accuracy of the prediction result can be effectively improved.
Optionally, each set of training data includes N pieces of training data, where each piece of training data includes cell information of a first cell of the terminal device and network service state information of the terminal device;
the N pieces of training data include N1 pieces of training data before the terminal device receives preset configuration information, and N2 pieces of training data after the terminal device receives the preset configuration information, where N, N1 and N2 are positive integers, and N is N1+ N2.
In this embodiment, each set of training data includes N pieces of training data, where each piece of training data includes cell information of a first cell of the terminal device and network service state information of the terminal device. Specifically, the terminal device may detect whether preset configuration information is received, and if the preset configuration information is received, may collect N1 pieces of training data before the preset configuration information is received, and N2 pieces of training data after the preset configuration information is received as a set of training data. In some embodiments of the present invention, the terminal device may buffer each set of training data for a circular queue of N using a window (window).
In a case that the target network satisfying the first preset condition is the first target network having a duration longer than a preset duration, the terminal device may collect only data of a period of time before and after receiving the preset configuration information as training data, so as to accurately collect meaningful training data.
For example, when the first target network is a 5G network, the preset configuration information may be EN-DC (E-UTRA New Radio Dual Connectivity, which refers to Dual Connectivity between a 4G Radio access network and a 5G) configuration information, and the EN-DC configuration information is sent to the terminal device by a network side device. Specifically, the terminal device collects N1 pieces of training data before receiving the EN-DC configuration information and N2 pieces of training data after receiving the EN-DC configuration information as a set of training data.
When the first target network is a 5G network, the network service status information of the terminal device may be used to indicate whether the terminal device uses a 5G network service. In particular, the first identification code may be used to indicate a 5G network service and the second identification code to indicate other network services.
It should be noted that the terminal device may import the collected training data into the model for training when the time for collecting the training data reaches a preset time and/or when the number of sets for collecting the training data reaches a preset number. In some embodiments of the present invention, each piece of training data may further include time information corresponding to the piece of training data.
Optionally, the cell information comprises at least a cell identification code.
In this embodiment, the Cell information at least includes a Cell identification code, such as a CGI (Cell Global Identifier). In some embodiments of the present invention, the cell information may further include a cell service quality.
Optionally, the first cell further includes a neighboring cell of the terminal device, and the cell information further includes a cell service quality.
In this embodiment, the first cell may further include a neighboring cell of the terminal device, and the cell information may further include cell service quality. The cell service Quality may include RSRP (Reference Signal Receiving Power) and/or RSRQ (Reference Signal Receiving Quality).
Optionally, before predicting the network environment of the terminal device according to the cell information and a preset model, the method further includes:
judging whether a service cell of the terminal equipment is a preset cell or not;
predicting the network environment of the terminal equipment according to the cell information and a preset model, wherein the predicting comprises the following steps:
and under the condition that the service cell of the terminal equipment is a preset cell, predicting the network environment of the terminal equipment according to the cell information and a preset model.
In this embodiment, before the step 102, the terminal device may further determine whether a serving cell of the terminal device is a preset cell, and execute the step 102 when the serving cell of the terminal device is the preset cell.
The preset cell may be a serving cell to which the terminal device is accessed in a daily movement trajectory of a user, that is, a serving cell in which the number of times of access of the terminal device is greater than a preset number of times. It can be understood that, only in the case that the serving cell of the terminal device is a preset cell, the network environment of the terminal device can be predicted more quickly and accurately according to a preset model. The method comprises the steps that the terminal equipment predicts the network environment of the terminal equipment under the condition that the service cell is the preset cell, so that the prediction accuracy can be improved, and the terminal equipment can be prevented from carrying out meaningless prediction, so that the power consumption of the terminal equipment is reduced.
Specifically, the terminal device determines, through the CGI, whether a serving cell of the terminal device is a preset cell, that is, may determine whether the CGI of the serving cell of the terminal device is a preset CGI (CGI of the preset cell).
Optionally, after predicting the network environment of the terminal device according to the cell information and a preset model, the method further includes:
and starting to search the target network when the predicted network environment of the terminal equipment has the target network meeting the first preset condition.
In this embodiment, when the predicted network environment of the terminal device has the target network that meets the first preset condition, the target network is searched, so that the target network can be searched in advance when the predicted network environment of the terminal device has the target network that meets the first preset condition, and the terminal device can be effectively prevented from residing in the currently accessed network for a long time. In addition, the situation that the terminal equipment misses the target network service due to the fact that the terminal equipment is not in time to access the target network when entering the target network meeting the first preset condition can be avoided.
For example, when the target network meeting the first preset condition is a 4G network, and if the predicted network environment of the terminal device has a 4G network, the terminal device starts to search for the 4G network, so that the terminal device can be prevented from staying in the 2G or 3G network for a long time after entering the environment with the 4G network.
When the target network meeting the first preset condition is a 5G network with duration longer than the preset duration, and under the condition that the predicted 5G network with duration longer than the preset duration exists in the network environment of the terminal equipment, the terminal equipment starts to search for the 5G network. For a terminal device with a 5G modem independent from other network modems, the manner in which the terminal device starts searching for a 5G network may specifically include turning on the 5G modem of the terminal device.
Referring to fig. 2, fig. 2 is a second flowchart of a method for controlling a terminal device according to an embodiment of the present invention, where the method is applied to the terminal device, and a main difference between the present embodiment and the previous embodiment is that a target network that meets a first preset condition in the present embodiment specifically includes a first target network whose duration is greater than a preset duration, as shown in fig. 2, the method includes the following steps:
Step 201 and step 202 are the same as step 101 and step 102 shown in fig. 1 of the present invention, and are not described again here.
In this embodiment, the target networks meeting the first preset condition include a first target network having a duration longer than a preset duration, and in this step, when the predicted network environment of the terminal device does not have the first target network having a duration longer than the preset duration, the modem corresponding to the first target network is turned off.
In this step, in a case that a first target network having a duration longer than a preset duration exists in the predicted network environment of the terminal device, a modem corresponding to the first target network is turned on.
The following describes the present embodiment in detail by taking the first target network as a 5G network as an example, but the present invention is not limited thereto.
In the early stage, the 5G network only partially covers and is sporadically distributed due to cost consideration and the spectrum characteristic of the 5G technology, and in the current 5G terminal equipment, a 5G modem is independent from modems of other networks, and the 5G modem is relatively high in power consumption when being turned on due to the fact that the complexity of the 5G technology is relatively high.
The EN-DC is a dual connection between a 4G radio access network and a 5G network, and in the dual connection, a data plane radio bearer may be independently served by an MeNB (macro base station) or an SeNB (secondary base station), or may be served by both the MeNB and the SeNB. The bearers are called MCGs (Master Cell Group) when served only by MeNB, SCGs (Secondary Cell Group) when served only by SeNB, and split bearers when served by MeNB and SeNB. In the embodiment of the invention, the SCG is configured by 5G, namely, a main control process is carried out on an LTE (Long Term Evolution) cell, and the speed is increased through a 5G auxiliary cell group, so that the high-speed low-delay effect of 5G is achieved. Although an LTE primary cell is accessed, and the characteristics of 5G are supported, such an LTE cell may be used as a 5G cell, and hereinafter, such a cell is collectively referred to as an EN-DC cell.
The identification mode of the EN-DC cell can be determined by the EN-DC support Information of the network side device in the System Information 2(System Information 2). The mode of configuring the 5G auxiliary cell group in the connected state is as follows: under the requirement of throughput or time delay, configuring a 5G secondary cell group for the terminal equipment through an RRC (Radio Resource Control) reconfiguration message of the LTE cell.
However, since the 5G network coverage is sporadic, if the user can use the 5G service for a short time while moving, turning on the 5G modem consumes a large amount of power. In addition, the terminal device does not receive the EN-DC support information sent by the network side device in the LTE cell, but receives the 5G cell measurement command or the EN-DC configuration information sent by the network side device in the connected state, and the terminal device may miss the EN-DC service because it is not time to start the 5G modem to perform the 5G cell measurement.
According to the embodiment provided by the invention, the future network environment of the terminal equipment is predicted, and when a 5G network with the duration longer than the preset duration exists in the predicted network environment of the terminal equipment, the 5G modem is started; and when the predicted 5G network with the duration longer than the preset duration does not exist in the network environment of the terminal equipment, closing the 5G modem.
In this way, under the condition that a 5G network exists but the duration is short, the 5G modem is turned off, and the power consumption of the terminal equipment is reduced; and under the condition that the 5G network is predicted to exist and the duration is longer than the preset duration, the 5G modem is started, so that the condition that the EN-DC service is missed because the terminal equipment cannot start the 5G modem for 5G cell measurement is avoided.
In this embodiment, the control method of the terminal device obtains cell information of a first cell of the terminal device, where the first cell at least includes a serving cell of the terminal device; predicting the network environment of the terminal equipment according to the cell information and a preset model; under the condition that a first target network with duration longer than preset duration does not exist in the predicted network environment of the terminal equipment, closing a modem corresponding to the first target network; and under the condition that a first target network with duration longer than preset duration exists in the predicted network environment of the terminal equipment, starting a modem corresponding to the first target network. Therefore, when the first target network with the duration longer than the preset duration does not exist in the predicted network environment, the modem corresponding to the first target network is closed, and the power consumption of the modem corresponding to the first target network is reduced, so that the power consumption of the terminal equipment can be effectively reduced.
Optionally, in a case that there exists a first target network with a duration longer than a preset duration in the predicted network environment of the terminal device, before turning on a modem corresponding to the first target network, the method further includes:
judging whether the terminal equipment meets a second preset condition, wherein the second preset condition comprises that the electric quantity of the terminal equipment is higher than a preset threshold value and/or the mobile network transmission rate of the terminal equipment is lower than a preset rate;
the starting a modem corresponding to a first target network when the predicted first target network with duration longer than a preset duration exists in the network environment of the terminal device includes:
and starting a modem corresponding to a first target network when the predicted network environment of the terminal equipment has the first target network with the duration longer than the preset duration and the terminal equipment meets the second preset condition.
In this embodiment, the terminal device may comprehensively determine, in combination with the predicted network environment of the terminal device and the current state of the terminal device, to turn on or turn off the modem corresponding to the first target network.
Specifically, the terminal device determines whether the terminal device meets a second preset condition, and starts a modem corresponding to a first target network when the predicted network environment of the terminal device has the first target network with duration longer than a preset duration and the terminal device meets the second preset condition.
The second preset condition includes that the electric quantity of the terminal equipment is higher than a preset threshold value, and/or the mobile network transmission rate of the terminal equipment is smaller than a preset rate. In this way, even if a first target network with a duration longer than a preset duration exists in the predicted network environment, the terminal device only starts a modem corresponding to the first target network when the electric quantity is higher than a preset threshold and/or the transmission rate of the mobile network is lower than a preset rate.
Optionally, after determining whether the terminal device meets a second preset condition, the method further includes:
and closing the modem corresponding to the first target network under the condition that the terminal equipment does not meet the second preset condition.
In this embodiment, when the terminal device does not satisfy the second preset condition, the terminal device closes the modem corresponding to the first target network. In this way, no matter whether a first target network with duration longer than the preset duration exists in the predicted network environment or not, if the terminal device does not meet the second preset condition, the modem corresponding to the first target network is closed. Therefore, the power consumption of the terminal equipment can be reduced, and the endurance time of the terminal equipment is effectively prolonged.
