Detailed ways

In order to make those skilled in the art better understand the solutions of the present application, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application.

When the electronic device is disconnected from the network, it will conduct a network search to find and access the mobile communication network with the best signal. With the development of mobile communication technology, the current common mobile communication networks include the second generation mobile communication (2-Generation wireless telephone technology, 2G) network, the third generation mobile communication (3rd-Generation, 3G) network, the fourth generation mobile communication network. Communication (the 4th generation mobile communication technology, 4G) network, 5G network, etc. In some embodiments, the electronic devices that support 5G network connection usually perform network searches in the order of 5G, 4G, 3G, and 2G, wherein, when the network search for the network type in the first order fails, the network type in the order of the second order is performed. The network type of network to search for.

However, it is still in the early stage of 5G construction. The coverage of 5G base stations is very small, and only a few areas can search for 5G networks. The 5G network searches performed by electronic devices that support 5G network connections in these areas are usually ineffective. Regionally searching for 5G networks will lead to an unnecessary increase in the number of searches.

After long-term research, the inventor proposes a network search method, device and electronic equipment, which can reduce unnecessary network search times of electronic equipment, thereby improving network search speed and reducing power consumption waste of electronic equipment. The content is described in detail below.

Please refer to FIG. 1 . FIG. 1 is a schematic diagram of an application environment suitable for an embodiment of the present application. The electronic device 100 can access the mobile communication network through the network-side device 200, thereby realizing communication with other devices.

Wherein, the electronic device 100 can be any device that supports various generations of wireless communication services (such as the above-mentioned 2G, 3G, 4G, 5G), for example, can be an intelligent terminal (such as a mobile phone, a vehicle-mounted device, etc.), a tablet computer, a personal computer ( PersonalComputer, PC), etc. The network side device 200 can be any device that can be used by the electronic device 100 to access the mobile communication network, for example, it can be a base station, or it can be a remote radio unit (Remote Radio Unit, RRU) used to form a distributed base station. The embodiment is not limited in this regard.

The mobile communication network is usually a cellular network, and each network-side device 200 in the cellular network has a corresponding wireless signal coverage area, which is usually referred to as a cell or a cell (Cell). In the cell, the electronic device 100 can communicate with the network-side device 200 through wireless signals. As the location of the electronic device 100 changes, it can access different network-side devices 200, and the cell where the electronic device 100 is located will also change.

Please refer to FIG. 2 . FIG. 2 is a schematic flowchart of a network search method provided by an embodiment of the present application, and the method can be applied to the electronic device 100 shown in FIG. 1 . The steps included in the method are described below.

Step S110: Record the network type of the network to which the electronic device is currently connected as the priority search type, and use the location of the electronic device when the priority search type is recorded as the target location.

In this embodiment, the electronic device 100 may determine the network type to which the network to which the device is currently connected belongs one or more times. Wherein, in the scenario of multiple determinations, the time interval between each two determination operations may be the same, for example, the network type of the network currently connected to the electronic device 100 is determined according to a fixed time interval. The time interval may also be different, for example, after each time the network type of the network currently connected to the electronic device 100 is determined, the time to perform the next determination operation is randomly determined; for another example, an initial time interval may be set, according to The time interval is adjusted according to the motion state (eg, moving speed) of the electronic device 100, and the subsequent determination operation is performed according to the adjusted time interval. Specifically, the moving speed and the time interval may be in an inverse proportional relationship.

In the implementation process, when the electronic device 100 performs a determination operation, the determined network type can be directly recorded as the priority search type of the electronic device 100, wherein the location where the electronic device 100 records the priority search type is the target location.

When the electronic device 100 performs multiple determination operations, in one embodiment, the network type determined each time may be recorded as the priority search type of the electronic device 100, and the recording time of each priority search type may be saved; In one embodiment, the network type determined for the first time may be recorded as the priority search type of the electronic device 100, and when the network type of the network connected to the electronic device 100 is subsequently re-determined, the recorded priority search type may be updated to be determined again. Network Type. Wherein, the position of the electronic device 100 when the priority search type is recorded or updated for the latest time is the target position.

Step S120, when the electronic device is disconnected from the network, determine the relative distance between the current position of the electronic device and the target position.

In practical applications, when the electronic device 100 enters a range where the mobile communication network is not covered or the mobile communication signal is poor, or a period of time (eg, within a few seconds) after being turned off and turned on again, the electronic device 100 will be in a disconnected state. When the electronic device 100 detects that the device is in a disconnected state, it can detect the relative distance between the current position of the device and the aforementioned target position.

Step S130, determining whether the relative distance reaches a set value. If no, go to step S140, if yes, go to step S150.

Step S140, searching for the network of the priority search type.

In step S150, a network search is performed according to the set search order.

In this embodiment, the set value can be set flexibly, for example, it can be set according to experience or statistical data. Wherein, if the relative distance between the location of the electronic device 100 when the network is disconnected and the target location does not reach the set value, it can be determined that the location of the electronic device 100 when the network is disconnected is relatively close to the target location. In view of the fact that the network coverage is basically fixed in a certain area, if the location of the electronic device 100 when the network is disconnected is relatively close to the target location, the network coverage of the location of the electronic device 100 when the network is disconnected and the network coverage of the target location are likely to be different. Likewise, thus, the network to which the electronic device 100 is connected at the target location (the network of the recorded priority search type) may be searched first. For example, assuming that the 5G network is not deployed in the area A, the priority search type recorded or updated by the electronic device 100 at the location s1 in the area A is usually 4G. Correspondingly, if the relative distance between the electronic device 100 and the location s1 is less than the set At the position s2 of the value, for example, if the network is disconnected due to entering an elevator or an underground garage, the 4G network can be searched first instead of the 5G network, which can reduce the number of network searches.

Correspondingly, if the relative distance between the location of the electronic device 100 when the network is disconnected and the target location reaches the set value, it means that the location of the electronic device 100 when the network is disconnected is far away from the target location, and the network coverage at the two locations is likely to be different. , so that the network search can be performed according to the network search order set in the electronic device 100 . The set search order may be a search order optimized according to a specific strategy, or may be a default search order, such as searching in the order of 5G, 4G, 3G, and 2G.

Through the process shown in Figure 2, in most cases, the network that the electronic device searches first when the network is disconnected is the network covered by the current location, which can reduce the number of network searches and improve the speed of network searching, thereby reducing unnecessary waste of power consumption of electronic devices. .

Please refer to FIG. 3 , which is a schematic flowchart of a network search method provided by another embodiment of the present application. The method can be applied to the electronic device 100 shown in FIG. 1 , and the steps included in the method are described below.

Step S210: Record the network type of the network to which the electronic device is currently connected as the priority search type, and use the location of the electronic device when the priority search type is recorded as the target location.

Step S220, when the cell where the electronic device is located changes, re-determine the network type to which the network that the electronic device is currently connected to belongs to, and update the priority search type to the re-determined network type.

In this embodiment, the process of repeatedly determining the network type to which the network currently connected to the electronic device 100 belongs may be implemented through steps S210-S220. The cell where the electronic device 100 is located refers to the cell where the electronic device 100 resides. The network type of the network to which the electronic device 100 is connected is usually changed only when the cell where the electronic device 100 is located changes. Based on this, in this embodiment, a change in the cell where the electronic device 100 is located is used as a trigger condition to trigger execution: determine the network type to which the network currently connected to the electronic device 100 belongs, and update the recorded priority search type to the re-determined network type of step. In this way, it can basically be ensured that the priority search type recorded is the type of the network to which the electronic device 100 is most recently connected, that is, the real-time recording of the network type to which the electronic device 100 is connected can be basically realized.

In addition, since the network search mechanism of the electronic device 100 is to select the network with the best signal quality from the available networks, with the method of this embodiment, the electronic device 100 can determine that the disconnection occurs in most cases of network disconnection. The best network type covered by the location where the network is located, and the network of the best network type is searched first.

Optionally, in this embodiment, when the electronic device 100 records the priority search type for the first time, it may record the cell information of the cell where the electronic device 100 is currently located. Subsequently, if it is detected that the cell where the electronic device 100 is located changes, the recorded cell information is updated. The cell information may be, for example, the ID of the cell. In one embodiment, it may be the physical layer ID of the cell, and in another embodiment, it may be the ID assigned to the cell by the operator, which is not limited in this embodiment. .

Step S230, when the electronic device is disconnected from the network, use the position of the electronic device when the priority search type was last updated as the target position, and determine the relative distance between the current position of the electronic device and the target position .

Step S240, determining whether the relative distance reaches a set value. If not, go to step S250, if yes, go to step S260.

Step S250, searching for the network of the priority search type.

Step S260, perform a network search according to the set search order.

In this embodiment, if it is detected that the electronic device 100 is in a disconnected state, the relative distance between the position (ie, the target position) of the electronic device 100 when the priority search type was last updated and the current position of the electronic device 100 is obtained, And judge whether the relative distance reaches the set value. The process of executing the judgment is similar to step S130 to step S150 in the previous embodiment, which is not repeated here.

Through the process shown in Fig. 3, it can be ensured that the electronic device will preferentially search for the network covered by the location when the network is disconnected in most network disconnection scenarios. Therefore, the number of times of searching the network is reduced, the speed of searching the network is increased, and the waste of power consumption caused by the ineffective network search is reduced.

Optionally, in this embodiment, when the cell where the electronic device 100 is located changes, before or after the priority search type is updated, the current geographic location of the electronic device 100 may be acquired as the last update of the electronic device 100. The location at which the type is searched is given priority. In this way, when the electronic device 100 is disconnected from the network, the current geographic location can be used as the target location. Wherein, the current geographic location of the electronic device 100 may be determined according to the current positioning information of the electronic device 100, and the current positioning information may be, for example, current satellite positioning information or current network positioning information.

In this embodiment, in step S230, the step of determining the relative distance between the current position of the electronic device 100 and the target position may be implemented in the following manner:

Obtain the geographic location of the electronic device when the network is disconnected, and calculate the distance between the geographic location when the network is disconnected and the target location (for example, Euclidean distance or Manhattan distance) to obtain the relative distance.

The geographic location of the electronic device 100 when the network is disconnected may be determined according to the positioning information (eg, satellite positioning information or network positioning information) of the electronic device 100 before the network disconnection. Considering that the range of the position of the electronic device 100 before and after the disconnection is limited, and the type of the network to which the electronic device 100 is connected changes at least in cell units, the electronic device 100 determined according to the positioning information before the disconnection of the network is determined. The geographic location of the device 100 can be used as the geographic location when the electronic device 100 is disconnected from the network.

Through the above method, the relative distance between the location of the electronic device when the network is disconnected and the target location can be more accurately determined, so that the determined network type that the electronic device first searches when the network is disconnected is more accurate, and unnecessary network searches are reduced. .

Please refer to FIG. 4 , which is a schematic flowchart of a network search method provided by another embodiment of the present application. The method can be applied to the electronic device 100 shown in FIG. 1 , and the electronic device 100 includes a pedometer. The steps of the method are described below.

Step S310: Record the network type of the network to which the electronic device is currently connected as the priority search type, and use the location of the electronic device when the priority search type is recorded as the target location.

Step S320, when the cell where the electronic device is located changes, re-determine the network type to which the network currently connected to the electronic device belongs, and update the priority search type to the re-determined network type.

Step S330, when the cell where the electronic device is located changes, set the step count value of the pedometer of the electronic device to an initial value, and control the pedometer to count steps.

In this embodiment, the process for the electronic device 100 to repeatedly determine the network type to which the network currently connected to the device belongs may be implemented through steps S310-S320.

The electronic device 100 may perform step S310 when determining the cell where it is located for the first time, and turn on the pedometer at this time. Before it is detected for the first time that the cell where the electronic device 100 is located has changed, if the electronic device 100 is disconnected from the network, it can be processed according to step S340. Then, the step count value of the pedometer when the electronic device 100 is disconnected from the network can represent the relative distance between the location of the electronic device 100 when the network is disconnected and the target location, and then process according to steps S350-S370.

In this embodiment, the initial value of the pedometer can be set flexibly, and for convenience of calculation, for example, it can be 0. Correspondingly, when the ith time (i is a positive integer greater than or equal to 1) detects that the cell where the electronic device 100 is located changes, the electronic device 100 can clear the step count value of the pedometer to restart counting . Then, processing can be performed according to steps S340-S370 described later.

It is worth noting that, in this embodiment, there is no restriction on the execution order of updating the priority search type and controlling the pedometer to count steps. In other words, there is no restriction on the sequence of steps S320 and S330. execute in parallel.

Step S340, when the electronic device is disconnected from the network, take the position where the electronic device was last when the priority search type was updated as the target position, and obtain the pedometer of the electronic device on the electronic device. The step count value when the network is disconnected is taken as the relative distance between the current position of the electronic device and the target position.

Among them, because the pedometer restarts counting every time the cell where the electronic device 100 is located changes, and the priority search type is updated every time the cell where the electronic device 100 is located changes, therefore, the pedometer is used in the electronic device. The pedometer value when 100 is disconnected from the network represents the distance between the position (target position) of the electronic device 100 when its priority search type was last updated and the current position of the electronic device 100 . Based on this, the electronic device 100 may use the pedometer value obtained when the network is disconnected as the relative distance.

It should be noted that, in a practical application, in a situation, when the electronic device enters a range not covered by a mobile communication network or enters a range where the signal of the mobile communication network is poor, a network disconnection will occur. In another situation, a network disconnection occurs within a period of time (eg, a few seconds) after the electronic device is turned off and restarted.

For the former case, the processing can be directly performed according to steps S340 to S370 shown in FIG. 4 . For the latter case, in the scenario where the pedometer is used to determine the relative distance between the location of the electronic device 100 when the network is disconnected and the target location, the shutdown time can be stored in the non-temporary non-temporary location of the electronic device 100 when the shutdown instruction is received. In the state memory, when the electronic device 100 is turned on, the current time is obtained, and the interval between the current time and the saved shutdown time is determined. Steps S340-S370 are processed.

Step S350, determine whether the relative distance reaches a set value. If no, go to step S360, if yes, go to step S370.

Step S360, searching for the network of the priority search type.

Step S370, perform network search according to the set search order.

The detailed implementation process of step S350-step S370 is similar to the implementation process of step S130-step S150 and step S240-step S260 in the foregoing embodiment, and will not be repeated here.

Through the process shown in FIG. 4 , the probability that the electronic device will preferentially search for the network that is not covered by the current location when the network is disconnected can be reduced, thereby reducing the number of invalid network searches, improving the efficiency of network searching, and reducing unnecessary waste of power consumption.

Optionally, in this embodiment, the set value may be determined in different ways.

As shown in FIG. 5 , in an implementation manner, before step S350 is performed, the network search method provided in this embodiment may further include the following steps:

Step S510: Determine the distance threshold corresponding to the network type according to the coverage radius of the base station of each network type, and save the corresponding relationship between the network type and the distance threshold.

Among them, base stations of different network types have different coverage radii. For example, the coverage radius of a 2G base station is about 5-10 kilometers, the coverage radius of a 3G base station is about 2-5 kilometers, and the coverage radius of a 4G base station is about 1-3 kilometers. , the coverage radius of 5G base station is about 100-300 meters. In this embodiment, for each network type, for example, the center value of the coverage radius of the base station of the network type may be obtained, and the average value may be multiplied by a preset multiple (eg, 2-5 times) to obtain a distance value. In the case of calculating the relative distance through geographic location, the obtained distance value can be directly used as the distance threshold value corresponding to the network type, and in the case of determining the relative distance between the position of the electronic device 100 when the network is disconnected and the target position through the pedometer , the obtained distance value can be converted into a step value, and the obtained step value is the distance threshold corresponding to the network type.

Taking a 5G base station as an example, it can be determined that the center value of its coverage radius is 200 meters, then 200 meters can be multiplied by a multiple of 3 to obtain a distance value of 600 meters. The meter is used as the distance threshold corresponding to 5G; when the relative distance is determined by the pedometer, the step value converted from 600 meters can be used as the distance threshold corresponding to 5G.

After the distance threshold corresponding to each network type is determined, the correspondence between the network type and the distance threshold may be saved, and the correspondence may be a data record including the network type and the distance threshold.

Step S520: Find a distance threshold corresponding to the priority search type according to the corresponding relationship as the set value.

After the electronic device 100 is disconnected from the network and the relative distance between the current position of the device and the target position is determined, the recorded priority search type can be used as an index to search for the corresponding relationship including the priority search type from the saved corresponding relationship, and then the search The distance threshold in the corresponding relationship is taken as the set value, and then step S350 is performed based on the set value.

As shown in FIG. 6 , in another implementation manner, before step S350 is performed, the network search method provided in this embodiment may further include the following steps:

Step S610, for each operator network, determine the distance threshold corresponding to the operator and the network type according to the coverage radius of the base station of each network type of the operator network, and save the operator network, network type and distance threshold corresponding relationship.

In this embodiment, the operator network may be any mobile communication network that provides mobile communication services for users. For each operator's network, the coverage radius of the base station of each network type of the operator can be obtained, and then the distance threshold corresponding to each network type of the operator is determined according to a process similar to the above step S510. Wherein, the corresponding relationship in step S610 may be a data record including the operator's network identifier, network type and distance threshold.

Step S620, according to the public land mobile network (Public Land Mobile Network, PLMN) currently selected by the electronic device, determine the operator network currently to be accessed by the electronic device.

Wherein, when the electronic device 100 searches for a network, it usually selects a PLMN, and then searches for an available network within the range of the PLMN. The PLMN may include a Mobile Country Code (MCC) and a Mobile Network Code (MNC), wherein the MCC is used to identify the country to which the electronic device 100 belongs, and the MNC is used to identify the operation of the electronic device 100 in the country. business network.

Step S630, according to the corresponding relationship, determine a distance threshold corresponding to the operator network to be accessed and the priority search type as the set value.

During the implementation process, the electronic device 100 may use the identifier of the operator network to be accessed currently (for example, MNC) and the priority search type as an index, and search for the information including the operator network currently to be accessed from the saved correspondence. The corresponding relationship between the identification and the priority search type is identified, and the distance threshold in the found corresponding relationship is used as the set value, and step S350 is performed based on the determined set value.

Through the processes shown in FIG. 5 and FIG. 6 , a more accurate judgment can be made on the distance between the position of the electronic device 100 when the network is disconnected and the target position when the priority search type was last recorded or updated. It is possible to reduce the situation that the electronic device 100 searches for a network that is not deployed at the current location when the network is disconnected, further reducing the number of times of network searching, increasing the speed of searching the network, and reducing power consumption.

It can be understood that, in other embodiments of the present application, the set value can also be determined through the process shown in FIG. 5 or FIG. 6 .
