Detailed Description
In order to make the technical solutions better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.
When the electronic equipment is in the network disconnection state, network search is carried out to find out and access the mobile communication network with the best signal. With the development of mobile communication technology, currently, common mobile communication networks include a 2-Generation wireless telephone technology (2G) network, a 3rd-Generation 3G network, a fourth-Generation mobile communication technology (4G) network, a 5G network, and the like. In some embodiments, the electronic device supporting 5G network connection generally performs network searches in the order of 5G, 4G, 3G, and 2G, wherein when a network search for a network type ranked earlier fails, a network of a network type ranked later is searched.
However, at present, in the initial stage of 5G construction, the coverage of the 5G base station is very small, only a very small number of areas can search for the 5G network, and the 5G network search performed in these areas by the electronic device supporting 5G network connection is usually ineffective, and the preferential search for the 5G network in these areas may result in an unnecessary increase of the network searching times.
The inventor provides a network searching method, a network searching device and electronic equipment through long-term research, and can reduce unnecessary network searching times of the electronic equipment, thereby improving the network searching speed and reducing the power consumption waste of the electronic equipment. This is explained in detail below.
Referring to fig. 1, fig. 1 is a schematic diagram of an application environment suitable for the embodiment of the present application. The electronic device 100 may access a mobile communication network through the network-side device 200, thereby implementing communication with other devices.
The electronic device 100 may be any device that supports various generations of wireless communication services (such as the above-mentioned 2G, 3G, 4G, and 5G), and may be, for example, a smart terminal (e.g., a mobile phone, an in-vehicle device, etc.), a tablet Computer, a Personal Computer (PC), etc. The network side device 200 may be any device that can provide the electronic device 100 with access to a mobile communication network, for example, may be a base station, and may also be a Remote Radio Unit (RRU) for forming a distributed base station, which is not limited in this embodiment of the present application.
The mobile communication network is typically a cellular network, and each network-side device 200 in the cellular network has a corresponding radio signal coverage area, which is commonly referred to as a Cell or a Cell (Cell). Within the cell, the electronic device 100 may communicate with the network-side device 200 through a wireless signal. As the location of the electronic device 100 changes, the electronic device 100 may access different network-side devices 200, and the cell in which the electronic device is located also changes.
Referring to fig. 2, fig. 2 is a flowchart illustrating a network searching method according to an embodiment of the present application, where the method can be applied to the electronic device 100 shown in fig. 1. The steps involved in the method are explained below.
Step S110, recording a network type to which a network currently connected by the electronic device belongs as a priority search type, and taking the position of the electronic device when the priority search type is recorded as a target position.
In this embodiment, the electronic device 100 may determine the network type to which the network currently connected to the device belongs one or more times. 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 to which the electronic device 100 is currently connected is determined according to a fixed time interval. The time interval may also be different, such as randomly determining the time for performing the next determination operation after determining the network type of the network to which the electronic device 100 is currently connected; for another example, an initial time interval may be set, the time interval may be adjusted according to the motion state (e.g., moving speed) of the electronic device 100, and the subsequent determination operation may be performed according to the adjusted time interval, in detail, the moving speed and the time interval may be in an inverse proportional relationship.
In the implementation process, in the case that the electronic device 100 performs one determination operation, the determined network type may be directly recorded as the priority search type of the electronic device 100, where a position where the electronic device 100 records the priority search type is a target position.
In the case that the electronic device 100 performs multiple determination operations, in one embodiment, the network type determined each time may be recorded as a priority search type of the electronic device 100, and a recording time of each priority search type may be saved; in another embodiment, the first determined network type 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 determined again, the recorded priority search type may be updated to the determined network type again. The position where the electronic device 100 is located when the priority search type is recorded or updated last time is the target position.
Step S120, when the electronic equipment is disconnected, determining the relative distance between the current position of the electronic equipment and the target position.
In practical applications, the electronic device 100 is in a power-off state when it enters a range that does not cover the mobile communication network or the mobile communication signal is poor, or when it is turned on again after being turned off (for example, within a few seconds). When detecting that the device is in the network disconnection state, the electronic device 100 may detect a relative distance between a current location of the device and the aforementioned target location.
Step S130, determining whether the relative distance reaches a set value. If not, go to step S140, and if so, go to step S150.
Step S140, searching the network with the priority search type.
Step S150, performing a network search according to the set search order.
In this embodiment, the setting value may be flexibly set, for example, according to experience or statistical data. If the relative distance between the position of the electronic device 100 when the network is disconnected and the target position does not reach the set value, it may be determined that the position of the electronic device 100 when the network is disconnected and the target position are relatively close to each other. In view of the fact that the network coverage is substantially fixed in a certain area, if the location of the electronic device 100 when disconnected is close to the target location, the network coverage of the location of the electronic device 100 when disconnected is likely to be the same as the network coverage of the target location, and thus, the network (the recorded network of the priority search type) to which the electronic device 100 is connected at the target location may be searched first. For example, assuming that the area a does not deploy a 5G network, the type of the preferential search recorded or updated by the electronic device 100 at the location s1 in the area a is generally 4G, and correspondingly, if the electronic device 100 is at the location s2 at which the relative distance from the location s1 is smaller than the set value, for example, a network is disconnected due to entering an elevator or an underground garage, etc., the 4G network may be preferentially searched without searching the 5G network, and the number of network searches may be reduced.
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 indicates that the location of the electronic device 100 when the network is disconnected and the target location are far apart, and the network coverage conditions at the two locations are 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 network searching order may be a network searching order optimized according to a specific strategy, or may be a default network searching order, such as searching in sequence according to 5G, 4G, 3G, and 2G.
Through the process shown in fig. 2, the network preferentially searched by the electronic device during network disconnection is mostly the network covered by the current location, so that the network searching times can be reduced, the network searching speed can be increased, and unnecessary power consumption waste of the electronic device can be reduced.
Referring to fig. 3, fig. 3 is a flowchart illustrating a network searching method according to another embodiment of the present application, where the method can be applied to the electronic device 100 shown in fig. 1, and steps included in the method are described below.
Step S210, recording a network type to which a network currently connected to the electronic device belongs as a priority search type, and taking a position of the electronic device when the priority search type is recorded as a target position.
Step S220, when the cell where the electronic device is located changes, re-determining the network type to which the network currently connected to the electronic device belongs, and updating the priority search type to the re-determined network type.
In this embodiment, the process of determining the network type to which the network currently connected to the electronic device 100 belongs for multiple times may be implemented through steps S210 to S220. The cell in which the electronic device 100 is located refers to a cell in which the electronic device 100 resides. The type of network in which the electronic device 100 is connected to may change, typically, when the cell in which the electronic device 100 is located changes. Therefore, the embodiment takes the cell change where the electronic device 100 is located as a trigger condition to trigger execution of: and determining the network type to which the network currently connected by the electronic device 100 belongs, and updating the recorded priority search type to the redetermined network type. In this way, it is basically ensured that the priority search type of the record is the type of the network to which the electronic device 100 is newly connected, i.e. real-time recording of the type of the network to which the electronic device 100 is connected is basically achieved.
In addition, since the network searching mechanism of the electronic device 100 is to select the network with the best signal quality from the available networks, with the method of the embodiment, when the electronic device 100 is in most cases of network outage, it may determine the best network type covered by the location where the network outage occurs, and preferentially search for the network of the best network type.
Optionally, in this embodiment, when the electronic device 100 records the priority search type for the first time, it may record cell information of a cell in which the electronic device 100 is currently located. And subsequently, if the change of the cell in which the electronic equipment 100 is positioned is detected, updating the recorded cell information. The cell information may be, for example, an ID of a cell, and in one embodiment, the cell information may be a physical layer ID of the cell, and in another embodiment, the cell information may be an ID allocated to the cell by an operator, which is not limited in this embodiment.
Step S230, when the electronic device is disconnected, taking a location where the electronic device has updated the priority search type last time as the target location, and determining a relative distance between the current location of the electronic device and the target location.
Step S240, determining whether the relative distance reaches a set value. If not, go to step S250, and if so, go to step S260.
And step S250, searching the network with the priority search type.
Step S260, a network search is performed according to the set search order.
In this embodiment, if it is detected that the electronic device 100 is in the disconnected state, the relative distance between the position (i.e., the target position) where the electronic device 100 is located when the priority search type is updated last time and the current position of the electronic device 100 is obtained, and whether the relative distance reaches the set value is determined. The process of performing the determination is similar to the steps S130 to S150 in the previous embodiment, and is not described herein again.
Through the process shown in fig. 3, it can be ensured that the electronic device performs the preferential search on the network covered by the location in the network disconnection situation in most of the network disconnection situations, that is, the situation that the electronic device preferentially searches the network not covered by the current location in the network disconnection situation can be reduced, so that the network searching frequency is reduced, the network searching speed is increased, and the power consumption waste caused by performing the invalid network search is reduced.
Optionally, in this embodiment, when the cell in which 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 location where the electronic device 100 has been recently updated with the priority search type, so that the current geographic location may be used as the target location when the electronic device 100 is disconnected. The current geographic location of the electronic device 100 may be determined based on current location information of the electronic device 100, which may be, for example, current satellite location information or current network location 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 by:
and acquiring the geographical position of the electronic equipment when the network is disconnected, and calculating the distance (for example, the Euclidean distance or the Manhattan distance) between the geographical position of the electronic equipment when the network is disconnected and the target position to obtain the relative distance.
The geographic location of the electronic device 100 when disconnected from the network may be determined based on positioning information (e.g., satellite positioning information or network positioning information) of the electronic device 100 prior to the network being disconnected. Considering that the electronic device 100 has a limited range of location change before and after the time of network disconnection, and the type of the network to which the electronic device 100 is connected changes at least in units of cells, the geographical location of the electronic device 100 determined from the positioning information before the network disconnection of the electronic device 100 may be used as the geographical location of the electronic device 100 when the network is disconnected.
By the method, the relative distance between the position of the electronic equipment and the target position when the network is disconnected can be accurately determined, so that the determined network type firstly searched by the electronic equipment when the network is disconnected is more accurate, and unnecessary network searching times are reduced.
Referring to fig. 4, fig. 4 is a flowchart illustrating a network searching method according to another embodiment of the present application, where 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 explained below.
Step S310, recording the network type of the network which is currently connected with the electronic equipment as a priority search type, and taking the position of the electronic equipment when the priority search type is recorded as a target position.
Step S320, when the cell where the electronic device is located changes, re-determining the network type to which the network currently connected to the electronic device belongs, and updating the priority search type to the re-determined network type.
And step S330, when the cell where the electronic equipment is located changes, setting the step counting value of the pedometer of the electronic equipment as an initial value, and controlling the pedometer to count steps.
In this embodiment, the process of determining, by the electronic device 100, the network type to which the network currently connected to the device belongs for multiple times may be implemented through steps S310 to S320.
When the electronic device 100 determines the located cell for the first time, the electronic device 100 may execute step S310 and start the pedometer at this time. Before the change of the cell in which the electronic device 100 is located is detected for the first time, if the electronic device 100 is disconnected, the processing may be performed according to step S340, and in detail, the location where the electronic device 100 is located when the priority search type recorded for the last time (i.e., the first time) is taken as the target location, then the step count value of the pedometer when the electronic device 100 is disconnected may represent the relative distance between the location and the target location when the electronic device 100 is disconnected, and then the processing is performed according to steps S350 to S370.
In this embodiment, the initial value of the pedometer may be flexibly set, and for convenience of calculation, for example, may be 0. Correspondingly, when the change of the cell in which the electronic device 100 is located is detected the ith time (i is a positive integer greater than or equal to 1), the electronic device 100 may clear the step count value of the pedometer to restart counting. Then, the processing may be performed in accordance with steps S340 to S370 described later.
It should be noted that, in this embodiment, there is no limitation on the execution order for updating the priority search type and controlling the pedometer to count steps, in other words, there is no limitation on the order of step S320 and step S330, and the steps may be executed sequentially according to a certain order or in parallel.
Step S340, when the electronic device is disconnected, taking a location where the electronic device last updated the priority search type as the target location, and obtaining a step count value of a pedometer of the electronic device when the electronic device is disconnected, as a relative distance between the current location of the electronic device and the target location.
Since the pedometer restarts counting each time the cell in which the electronic device 100 is located changes, and the priority search type is updated each time the cell in which the electronic device 100 is located changes, the step count value of the pedometer when the electronic device 100 is disconnected is characterized by: the distance between the position (target position) where the electronic apparatus 100 is located when its priority search type was updated last time and the current position of the electronic apparatus 100. Based on this, the electronic device 100 may use the step count value acquired when the network is disconnected as the relative distance.
It should be noted that, in practical applications, in one situation, the network disconnection occurs when the electronic device enters a range not covering the mobile communication network or enters a range with poor signal of the mobile communication network. In another situation, a network outage may occur within a period of time (e.g., several seconds) after the electronic device is powered off and restarted.
In the former case, the processing may be directly performed according to steps S340 to S370 shown in fig. 4. For the latter case, in a scenario where the pedometer is used to determine the relative distance between the location of the electronic device 100 and the target location when the network is disconnected, when a shutdown instruction is received, the shutdown time may be stored in the non-transitory memory of the electronic device 100, after the electronic device 100 is powered on, the current time is obtained, the interval between the current time and the stored shutdown time is determined, and if the interval is smaller than a set time length (e.g., 1 minute to 2 minutes), the processing is performed according to steps S340 to S370 shown in fig. 4.
Step S350, determining whether the relative distance reaches a set value. If not, go to step S360, and if yes, go to step S370.
And step S360, searching the network with the priority search type.
In step S370, a network search is performed according to the set search order.
The detailed implementation process of steps S350 to S370 is similar to the implementation process of steps S130 to S150 and steps S240 to S260 in the foregoing embodiment, and is not repeated here.
Through the process shown in fig. 4, the probability that the electronic device performs preferential search on the network which is not covered at the current position when the network is disconnected can be reduced, so that the invalid network searching times are reduced, the network searching efficiency is improved, and unnecessary power consumption waste is reduced.
Alternatively, in this embodiment, the set value may be determined in different manners.
As shown in fig. 5, in an implementation manner, before performing step S350, the network searching method provided in this embodiment may further include the following steps:
step S510, determining a distance threshold corresponding to each network type according to the coverage radius of the base station of the network type, and storing a corresponding relationship between the network type and the distance threshold.
The base stations of different network types have different coverage radii, for example, the coverage radius of the 2G base station is about 5-10 km, the coverage radius of the 3G base station is about 2-5 km, the coverage radius of the 4G base station is about 1-3 km, and the coverage radius of the 5G base station is about 100-300 m. In this embodiment, for each network type, for example, a center value of a coverage radius range of a base station of the network type may be obtained, and the average value is multiplied by a preset multiple (e.g., 2 to 5 times) to obtain a distance value. In the case of calculating the relative distance from the geographic location, the obtained distance value may be directly used as the distance threshold corresponding to the network type, and in the case of determining the relative distance between the location of the electronic device 100 when the network is disconnected and the target location by the pedometer, the obtained distance value may be converted into a step number, and the obtained step number is the distance threshold corresponding to the network type.
Taking a 5G base station as an example, if it can be determined that the center value of the coverage radius range is 200 meters, then the distance value of 600 meters can be obtained by multiplying the 200 meters by a multiple of 3, and in the case of calculating the relative distance by the geographic position, 600 meters can be taken as the distance threshold corresponding to 5G; in the case where the relative distance is determined by the pedometer, the step number converted from 600 meters may be used as the distance threshold corresponding to 5G.
After determining the distance threshold corresponding to each network type, a correspondence between the network type and the distance threshold may be saved, where the correspondence may be a data record including the network type and the distance threshold.
Step S520, finding the distance threshold corresponding to the priority search type according to the corresponding relationship, and using the distance threshold as the set value.
After the electronic device 100 is disconnected and the relative distance between the current location of the device and the target location is determined, the recorded priority search type may be used as an index, a corresponding relationship including the priority search type is searched from the stored corresponding relationship, then the distance threshold in the searched corresponding relationship is used as the set value, and step S350 is executed based on the set value.
As shown in fig. 6, in another embodiment, before executing step S350, the network searching method provided in this embodiment may further include the following steps:
step S610, for each operator network, determining a 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 storing a corresponding relationship between the operator network, the network type, and the distance threshold.
In this embodiment, the operator network may be any mobile communication network that provides a mobile communication service for a user. For each operator network, the coverage radius of the base station of each network type of the operator may be obtained, and then the distance threshold corresponding to each network type of the operator is determined according to the process similar to the above step S510. The corresponding relationship in step S610 may be a data record including an operator network identifier, a network type, and a distance threshold.
Step S620, determining an operator Network to be currently accessed by the electronic device according to a Public Land Mobile Network (PLMN) currently selected by the electronic device.
When searching for a network, the electronic device 100 typically selects a PLMN and searches for available networks within the PLMN.
