In the related art, network switching policies of a terminal device mainly include two types: one is that the handover of the network depends on the control of the network device, e.g. the network device assigns the terminal device to be handed over to a certain network cell to which the terminal device is handed over; and the other is that after the terminal equipment has network abnormality (such as incapability of surfing the internet and slow network speed), a command is sent from the code to actively trigger the switching of the network.

However, for the above two network switching strategies, on one hand, since the terminal device cannot actively select a network, some known bad network environments cannot be avoided, and the change of the network is passively waited for; on the other hand, the terminal device attempts to trigger a network handover after a bad network experience has occurred. Therefore, both the above-mentioned network switching strategies cannot avoid some networks known or having a high probability of poor experience in advance, so that situations such as slow internet surfing, jamming and the like are easy to occur.

Based on this, the embodiment of the application provides a network switching method, which can be applied to terminal equipment, and in a historical time window, first network information for executing at least one service at least one position is determined; at the target moment, if the target position in the at least one position executes the target service in the at least one service, searching second network information for executing the target service in the target position from the first network information; determining a network switching strategy of the target service according to the second network information; wherein the end time of the historical time window is no later than the target time. In this way, the terminal device can obtain the network switching strategy of the target service according to the second network information. Therefore, the terminal equipment can avoid some networks which are known or have poor experience with high probability in advance, so that the situations of slow surfing, blocking and the like are not easy to occur.

In order to facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The above related technologies may be optionally combined with the technical solutions of the embodiments of the present application, which all belong to the protection scope of the embodiments of the present application. Embodiments of the present application include at least some of the following.

Fig. 2 is a flowchart of a method for network handover according to an embodiment of the present application, where the method may be applied to a terminal device, as shown in fig. 2, and the method may include the following steps.

S210, determining first network information for executing at least one service at least one position in a historical time window.

For example, the historical time window may be a period of time before the current time. For example, the historical time window may be one week before the current time.

The at least one service may be at least one of a game, a video watching, a novel watching, or other services, which is not limited in the embodiment of the present application.

In some embodiments, the at least one location includes at least one subspace and/or at least one time period; wherein at least one time period is within the historical time window.

It should be noted that, the subspace may be consistent with or inconsistent with the actual spatial distribution, which is not limited in this embodiment of the present application.

For example, as shown in fig. 3, taking a home scenario as an example, the actual space distribution inside the home is three bedrooms (bedroom 1, bedroom 2 and bedroom 3), one toilet, one kitchen, one living room (including dining room), while according to the current software algorithm (signal strength division based on the router wifi), the home interior may be divided into 8 subspaces, and some subspaces are consistent with the actual space distribution, for example, the bedroom 1 corresponds to subspace 1, the bedroom 2 corresponds to subspace 2, the bedroom 3 corresponds to subspace 3, the kitchen corresponds to subspace 4, and the bathroom corresponds to subspace 5; some subspaces are not consistent with the actual spatial distribution, e.g. the living room is divided into subspaces 6, 7 and 8.

It should be noted that at least one time period is located in the historical time window, and it is understood that the at least one time period may be at least one time period in the historical time window.

For example, the historical time window may be one week before the target time, at which point the at least one time period may be at least one time period within one week before the target time. For example, the historical time window is 1 month 1 day 00:00 to 1 month 7 day 24:00 (prior to the target time), and the at least one time period may be 12:00 to 14:00 for 1 month 1 day to 1 month 7 day, 14:00 to 16:00 for 1 month 1 day to 1 month 7 day.

In some embodiments, determining first network information for performing at least one service at least one location may include: acquiring historical data of executing at least one service at least one location; and inputting the historical data into the first model to obtain first network information.

The history data is data acquired in a history time window.

Further, inputting the history data into the first model may include: the history data is input into the first model for preliminary processing (e.g., converting the history data into feature vectors).

It should be noted that the first model may be a model downloaded from a cloud server.

It should be further noted that the first model may be trained in advance at the cloud server.

By the method, the first network information can be obtained by inputting the historical data into the first model, so that the network switching can be realized based on the prediction of the first model.

S220, at the target moment, if the target position in the at least one position executes the target service in the at least one service, searching the second network information for executing the target service in the target position from the first network information.

Wherein the end time of the historical time window is no later than the target time.

The target time may be the current time or a time after the current time, which is not limited in the embodiment of the present application.

In some embodiments, the target location may include a target subspace and/or a target time period, wherein the target time period may be the time period in which the target time is located.

It should be noted that, in the case that the at least one location includes at least one subspace, the target location in the at least one location may be a target subspace in the at least one subspace. For example, assuming that at least one subspace includes bedroom 1, bedroom 2, and living room, the target subspace may be the living room.

It should be further noted that, in the case where the at least one location includes at least one time period, the target location in the at least one location may be a target time period in the at least one time period, where the time period represents the time period itself, and does not represent a specific time at which the time period is located. For example, assuming that the at least one time period includes 12:00 to 14:00, 14:00 to 16:00, 16:00 to 18:00, the target time period may be 16:00 to 18:00.

By way of example, the target service may be a game, provided that the at least one service includes a game, a video-watch, a novice.

It should be noted that, in the case that the target time is a time after the current time, after the terminal device obtains the network information of the target service executed in the target time period, the subsequent terminal device may directly use the network information when reaching the target time period to obtain the corresponding network switching policy.

It should be noted that, when the target time is a time after the current time, after the terminal device obtains the network information of the target subspace for executing the target service, the subsequent terminal device may directly use the network information when reaching the target subspace to obtain the corresponding network switching policy.

It will be appreciated that the target location at which the terminal device is located may be a changed location at the target time as compared to the previous time to the target time.

The target subspace in which the terminal device is located may be a changed subspace, for example. For example, the subspace in which the terminal device is located at the time immediately before the target time may be a bedroom, and the target subspace in which the terminal device is located at the target time may be a living room.

The target time period in which the terminal device is located may be a changed time period, for example. For example, the period of time in which the terminal device is located at the time immediately before the target time may be 14:00 to 16:00, and the target period of time in which the terminal device is located at the target time may be 16:00 to 18:00.

It will be appreciated that the target service performed by the terminal device at the target time may be a changed service, as compared to the previous time of the target time.

For example, the service executed by the terminal device at the time immediately before the target time may be a video, and the service executed by the terminal device at the target time may be a novice.

In some embodiments, the second network information may include at least one of:

priority of each of at least two network cells of the target service;

The network score of 4G and/or the network score of 5G of the target service; the method comprises the steps of,

the network score of the main card and the network score of the auxiliary card of the target service, and the flow value used by the main card and the flow value used by the auxiliary card.

By the method, after the terminal equipment obtains the second network information, the network switching strategy of the target service can be obtained subsequently based on the second network information. Therefore, the quality of the current network can be known in advance according to the historical experience, whether to switch to other networks can be determined in advance according to the quality of the current network, and situations of slow internet surfing, blocking and the like can be avoided in advance.

S230, determining the network switching strategy of the target service according to the second network information.

In some embodiments, the second network information may include priorities of respective at least two network cells; according to the second network information, determining the network switching policy of the target service may include: determining a target network cell of at least two network cells of the target service; determining the priority of the target network cell according to the priorities of at least two network cells; and determining a network switching strategy according to the priority of the target network cell.

It should be understood that the target network cell is a network cell to which the terminal device accesses.

It should be noted that, one network cell corresponds to one priority. The higher the priority of the network cell, the better the network after the terminal equipment is accessed to the network cell; the lower the priority of the network cell, the worse the network the terminal device has access to the network cell.

In the embodiment of the present application, the network handover policy is determined according to the priority of the target network cell, and the following several possible implementations are possible.

In one possible implementation, if the priority of the target network cell is located after the mth priority of the priorities of the at least two network cells, the operation of switching the target network cell or reselecting the target network cell is triggered.

Wherein M is a positive integer.

It should be noted that, the priority of the target network cell is located after the mth priority in the priorities of the at least two network cells, which is understood as the priority of the target network cell is located at the mth priority and the priority after the mth priority in the priorities of the at least two network cells.

It should be understood that, after the priority of the target network cell is located in the mth priority of the priorities of the at least two network cells, it is indicated that the network after the terminal device accesses the target network cell is worse, at this time, the terminal device may directly report the radio link failure (Radio Link Failure) to the network device and no longer report the measurement condition of the target network cell to the network device, so as to directly trigger the operation of switching the target network cell; or the terminal device may gradually reduce the measurement condition of the target network cell reported to the network device, and trigger the reselection of the target network cell.

By the method, the terminal equipment can trigger the operation of switching the target network cell or reselecting the target network cell under the condition that the network after the terminal equipment is accessed to the target network cell is poor, so that the conditions of slow surfing, blocking and the like of a plurality of known or high-probability networks with poor experience can be avoided in advance.

In another possible implementation, if the priority of the target network cell is located at the first priority of the priorities of the at least two network cells, the operation of switching the target network cell or reselecting the target network cell is not triggered.

It should be understood that the priority of the target network cell is located at the first priority of the priorities of at least two network cells, which indicates that the network after the terminal device accesses the target network cell is better, and the terminal device may not trigger the operation of switching the target network cell or trigger the operation of reselecting the target network cell.

By the method, the terminal equipment can not trigger the operation of switching the target network cell or reselecting the target network cell under the condition that the network after being accessed into the target network cell is good, and the situations of slow surfing, blocking and the like are not easy to occur at the moment.

In another possible implementation manner, if the priority of the target network cell is located at an nth priority among the priorities of the at least two network cells, determining whether to trigger the operation of switching the target network cell or reselecting the target network cell according to the accumulated network delay times.

Wherein N is a positive integer and N < M.

It should be understood that the priority of the target network cell is located at the nth priority of the priorities of the at least two network cells, where N < M indicates that the network may be unstable after the terminal device accesses the target cell, and the terminal device may determine whether to trigger the operation of switching the target network cell or reselecting the target network cell according to the accumulated network delay times.

It should also be appreciated that in the case where N is equal to 1, it may be determined whether to trigger the operation of switching the target network cell or reselecting the target network cell, not according to the accumulated number of network delays, but directly to perform the operation of not triggering the switching the target network cell or reselecting the target network cell.

Further, determining whether to trigger the operation of switching the target network cell or reselecting the target network cell according to the accumulated network delay times may include: if the accumulated network delay times are greater than a first preset value, triggering the operation of switching the target network cell or reselecting the target network cell; or if the accumulated network delay times are smaller than or equal to the first preset value, the operation of switching the target network cell or reselecting the target network cell is not triggered.

The first preset value may be a parameter value predefined by a protocol, or may be a parameter value set in other manners, which is not limited in the embodiment of the present application.

According to the method, the terminal equipment can determine whether to trigger the operation of switching the target network cell or reselecting the target network cell according to the accumulated network delay times under the condition that the network after the terminal equipment is connected with the target network cell is unstable, so that the conditions of slow surfing, blocking and the like of a network which are known or have high probability of poor experience can be avoided in advance.

In some embodiments, the second network information may include a network score of 4G and a network score of 5G; determining a network switching policy of the target service according to the second network information may include: and if the difference between the network score of 4G and the network score of 5G is greater than a second preset value, triggering the operation of closing 5G.

The second preset value may be a parameter value predefined by a protocol, or may be a parameter value set in other manners, which is not limited in the embodiment of the present application.

In the case where the second network information includes the network score of 4G and the network score of 5G, it is described that both of 4G and 5G are in the on state.

It should be appreciated that the difference between the network score of 4G and the network score of 5G is greater than the second preset value, indicating that the terminal device is in a network under 5G is poor, and at this time, the operation of closing 5G may be triggered so that the terminal device is in a network under 4G.

By the method, the operation of closing the 5G can be triggered under the condition that the network of the terminal equipment under the 5G is poor, so that the conditions of slow surfing, blocking and the like can be avoided in advance, which are known or have high probability of poor experience.

In some embodiments, the second network information may include a network score of 4G; according to the second network information, determining the network switching policy of the target service may include: determining a recommended 5G network score of the target service; and if the difference between the recommended network score of 5G and the network score of 4G is greater than a third preset value, triggering the operation of reselecting 4G and 5G.

The third preset value may be a parameter value predefined by a protocol, or may be a parameter value set in other manners, which is not limited in the embodiment of the present application.

In the case where the second network information includes the network score of 4G, the 4G is implicitly indicated to be in an on state, and the 5G is in an off state.

It should be further noted that the recommended 5G network score may be determined by the terminal device according to its own network state, or may be determined according to another manner, which is not limited in the embodiment of the present application.

It will be appreciated that the difference between the recommended network score for 5G and the network score for 4G is greater than the third preset value, indicating that the network with the terminal device under 5G may be better than the network with the terminal device under 4G at this time, and thus may trigger the operations of reselecting 4G and 5G, increasing the probability of returning to 5G.

By the method, when the difference between the recommended network score of 5G and the network score of 4G is larger than a third preset value, the operation of reselecting 4G and 5G can be triggered, so that the conditions of slow surfing, blocking and the like of a plurality of known or high-probability networks with poor experience can be avoided in advance.

In some embodiments, the second network information may include a network score of the primary card and a network score of the secondary card, a traffic value used with the primary card and a traffic value used with the secondary card; according to the second network information, determining the network switching policy of the target service may include: and if the difference between the network score of the auxiliary card and the network score of the main card is larger than a fourth preset value and the ratio of the flow value used by the main card to the flow value used by the auxiliary card is smaller than a fifth preset value, triggering the operation of switching from the main card to the auxiliary card.

The fourth preset value may be a parameter value predefined by a protocol, or may be a parameter value set in other manners, which is not limited in the embodiment of the present application.

The fifth preset value may be a parameter value predefined by a protocol, or may be a parameter value set in other manners, which is not limited in the embodiment of the present application.

It should be noted that, the ratio of the flow value used by the main card to the flow value used by the auxiliary card is smaller than the fifth preset value, so that the auxiliary card can be guaranteed to have a flow package.

It should be understood that the difference between the network score of the sub-card and the network score of the main card is greater than the fourth preset value, and the ratio of the flow value used by the main card to the flow value used by the sub-card is less than the fifth preset value, which indicates that the network is poor when the terminal device uses the main card, and at this time, the operation of switching from the main card to the sub-card can be triggered, so that the terminal device is in the network under the sub-card.

By the method, under the condition that the network is poor when the terminal equipment uses the main card, the operation of switching from the main card to the auxiliary card can be triggered, so that the conditions of slow internet surfing, blocking and the like can be avoided in advance, which are known or have high probability of poor experience.

It should be noted that, in the embodiment of the present application, the terminal device may perform at least one of the following: triggering an operation of switching the target network cell or reselecting the target network cell, triggering an operation of switching off 5G or reselecting 4G and 5G, and triggering an operation of switching from the main card to the sub card.

For example, after the terminal device triggers the operation of switching the target network cell or reselecting the target network cell, the operation of switching off 5G or reselecting 4G and 5G may be triggered.

For example, after the terminal device triggers the operation of switching the target network cell or reselecting the target network cell, the operation of switching from the main card to the sub card may be triggered.

The embodiment of the application provides a network switching method which can be applied to terminal equipment and is used for determining first network information for executing at least one service at least one position in a historical time window; at the target moment, if the target position in the at least one position executes the target service in the at least one service, searching second network information for executing the target service in the target position from the first network information; determining a network switching strategy of the target service according to the second network information; wherein the end time of the historical time window is no later than the target time. In this way, the terminal device can obtain the network switching strategy of the target service according to the second network information. Therefore, the terminal equipment can avoid some networks which are known or have poor experience with high probability in advance, so that the situations of slow surfing, blocking and the like are not easy to occur.

The method for network switching provided in the above embodiment is described in detail below in connection with a specific application scenario.

In this embodiment of the present application, the terminal device may collect historical data based on a specific environment (e.g., a home environment), input the historical data into the first model, output first network information that is located at least one location and performs at least one service, store the output result in a local offline database, and subsequently search, at a target moment, second network information that is located at a target location and performs a target service from the offline database, and obtain a network switching policy of the target service based on the second network information, so as to implement network advanced switching (e.g., switching of a target network cell, switching of another 4G/5G, and switching of another dual card, for example), so as to avoid an abnormal state, and promote user internet experience.

The technical scheme of the embodiment of the application mainly comprises the following two parts:

the first part is the prediction of the historical data (namely, inputting the historical data into a first model to obtain network information) and the preservation of the network information, and has the main functions of reading the historical data from a semantic map module, performing preliminary processing (such as vectorizing the historical data to obtain a feature vector), inputting the historical data into the first model downloaded from a cloud server, outputting the first network information of the terminal equipment in at least one position to execute at least one service after data operation in the model, and preserving the output result (namely, the first network information) in an offline preservation module, so that the subsequent use is convenient.

Fig. 4 is a schematic diagram of a framework for determining network information according to an embodiment of the present application. As shown in fig. 4, the framework may include a semantic map module 410, a data reading and processing module 420, a model management module 430, a cloud server 440, and an offline save module 450, wherein:

the data reading and processing module 420 may periodically read the history data (typically 1-2 weeks) from the semantic map module 410 and input the history data into the model management module 430; if the first model does not exist in the model management and control module 430, an http request may be sent, the first model may be downloaded from the cloud server 440, then the model management and control module 430 may input the historical data into the first model to perform operation, output the first network information that the terminal device is at least one location to perform at least one service, and store the output result in the offline storage module 450. In addition, in the offline saving module 450, old network information may be deleted and new first network information may be saved.

The second part is recommendation of second network information and switching of the network, and the second part is mainly used for triggering a recommendation service module to search second network information in the current subspace, the time period (namely a target position) and the service state (namely a target service) from an offline storage module according to the change of different states (such as subspace, time period and service state), and then recommending the second network information to an optimization module, wherein after receiving the second network information, the optimization module can obtain a network switching strategy based on the second network information and execute the network switching strategy, and then can feed back a network switching result to the recommendation service module.

Fig. 5 is a detailed flowchart of a method for network handover according to an embodiment of the present application. As shown in fig. 5, the detailed flow may include the steps of:

s510, registering the recommended service.

The optimization module registers the recommended service, and can subsequently receive the recommended second network information of the recommended service module.

S520, returning home.

After entering the fence (coming home), the recommendation service module starts working.

S530, acquiring second network information.

The recommendation service module waits for a state and monitors whether the subspace, the time period and the service state of the terminal equipment are changed or not; in the case where a subspace change (e.g., subspace ID change), a time period change (e.g., 3-point to 4-point), and a traffic state change (e.g., game play to video) occur, and the currently performed traffic is the target traffic, the recommendation service module may search the offline storage module for second network information in the current subspace, time period, and traffic state.

S540, adjusting the second network information according to the user preference.

The recommendation service module may adjust the second network information in the current subspace, time period, and traffic state according to user preferences. For example, in the case where the second network information includes a 5G network score in the current subspace, time period, and traffic state, the 5G network score may be increased according to user preferences.

S550, recommending second network information.

The recommendation service module recommends the second network information to the optimization module.

S560, feeding back a network switching result.

After receiving the second network information, the optimization module can execute a corresponding network switching strategy according to the second network information, and feed back a network switching result to the recommendation service module.

Wherein the network handover policy may include at least one of:

(1) In case the second network information comprises the priorities of the at least two network cells in the current subspace, the time period and the traffic state, the at least two network cells may be divided into a network cell of the best priority and a network cell of the worst priority, and a target network cell in the current subspace, the time period and the traffic state may be determined, the target network cell being the network cell to which the terminal device accesses.

If the priority of the target network cell is located after the mth priority of the priorities of the at least two network cells (the network cell corresponding to the worst priority), the measurement condition of the target network cell can be directly reported Radio Link Failure and no longer reported to the network device, so as to directly trigger the operation of switching the target network cell, or gradually reduce the measurement value reported to the network device, and trigger the reselection of the target network cell.

If the priority of the target network cell is located in the first priority (the network cell corresponding to top 1) of the priorities of at least two network cells, the operation of switching the target network cell or reselecting the target network cell is not triggered, i.e. no operation is performed.

If the priority of the target network cell is located in the nth priority of the priorities of the at least two network cells, whether to trigger the operation of switching the target network cell or reselecting the target network cell can be determined according to the accumulated network delay times.

(2) In case the second network information comprises a network score of 4G and/or a network score of 5G in the current subspace, time period and traffic state,

if the network score of 4G is greater than the network score a of 5G (i.e., the second preset value), the operation of closing 5G may be triggered, so that the terminal device is located under the 4G network; if the terminal device is currently in the 4G network and the recommended network score of 5G is > the network score b of 4G (i.e., the third preset value), then reselection from 4G to 5G is triggered, increasing the probability of returning to 5G.

(3) In the case that the second network information includes the network score of the main card and the network score of the sub card in the current subspace, the time period and the service state, and the traffic value used by the main card and the traffic value used by the sub card, if the network score of the sub card > the network score c score of the main card (i.e. the fourth preset value), and satisfies the traffic value used by the main card/the traffic value used by the sub card < d (i.e. the fifth preset value) (the traffic package is guaranteed for the sub card), the switch from the main card to the sub card can be triggered.

It should be noted that, the scenario to which the embodiment of the present application is applicable is not limited to a home scenario, but may also be extended to an office, etc.

It should be noted that the service executed by the terminal device is not limited to the game, but may be video watching, novice watching, or the like.

It should be noted that, when the current time is the same, the network information of the next time (for example, after half an hour) may be queried first, so that after the next time is entered, the network switching policy may be determined directly according to the network information of the next time; when the network information of the current subspace is searched, the network information of the adjacent subspace can be searched at the same time, so that after the adjacent subspace is accessed, the network switching strategy can be directly determined according to the network information of the adjacent subspace.

In the embodiment of the application, the terminal equipment can know the quality of the current network in advance according to the history experience under the current subspace, the time period and the service state, so that whether to switch to other networks can be determined in advance according to the quality of the current network, and the situations of slow internet surfing, blocking and the like can be avoided in advance.
