At present, a smart phone with the function of full Frequency band of full network communication at least supports sixteen Frequency bands under seven modes such as GSM (Global System for mobile communication), CDMA2000(Code Division Multiple Access2000, Code Division Multiple Access), WCDMA (Wideband Code Division Multiple Access), TD-SCDMA (Time Division-Synchronous Code Division Multiple Access), FDD-LTE (Frequency Division-Long Term Evolution, Frequency Division duplex Long Term Evolution) and TDD-LTE (Time Division-Long Term Evolution, Time Division duplex Long Term Evolution), when a terminal is in a network-free state, such as a mobile phone startup mode, a mobile phone shutdown flight mode, a mobile phone signal-free region entering a network-signal-free region, a mobile phone registration region, and a mobile phone out-of-service region, and a network-out-of-service region, at this time, the terminal often searches for a network in a full-mode full-band manner until a suitable network is found for registration. Therefore, the network searching method usually needs to consume more time, and consumes a large amount of power, which is prone to cause the problems of slow network searching speed and more power consumption of the terminal.

Therefore, the second network parameters are screened for the second time through the first geographic position and the SIM card, and then the network searching can be carried out in a targeted manner when the network searching is carried out through the screened second network parameters, wherein, as the network parameters which do not exist in the first geographic position are not required to be searched, and the network parameters which do not support the SIM card are not required to be searched, the useless searching process can be greatly reduced, and much time can be saved invisibly, thereby the problem caused by blind searching in a full-mode full-frequency band can be avoided, the network searching efficiency is improved, and the power consumption of the terminal is reduced.

Various embodiments of the method of the present invention will be presented below based on the above-mentioned mobile terminal hardware structure.
The technical solution of the present invention is further elaborated below with reference to the drawings and the specific embodiments.
Example one
The embodiment of the present invention provides a method for searching a network, which is applied to a terminal, and in practical application, the terminal may be an electronic device supporting a multi-mode and multi-band function, such as a smart phone for all-network communications, or may be another electronic device, such as a dual-card dual-standby mobile phone. Further, the functions implemented by the method for searching for a network may be implemented by a processor in the terminal calling program code, although the program code may be stored in a computer storage medium, and it is understood that the terminal includes at least a processor and a storage medium.
In practical application, the method for searching the network can be applied to various occasions that the terminal is in a network-free state and needs to search the network, for example, when the terminal is just started and is not registered to the network, the terminal enters an area with the network from a network-free area, the terminal is just closed and has a flight mode and is not registered to the network, the terminal enters a closed environment from an open environment, and the like.
Fig. 2 is a flowchart illustrating a method for searching a network according to a first embodiment of the present invention, referring to fig. 2, the method includes:
s201: when the terminal is in a network-free state, acquiring a first geographical position where the terminal is currently located;
specifically, when the terminal is in a no-network state, the terminal needs to perform network search. Generally, for a terminal supporting multiple network systems, i.e. a multi-mode and multi-band function, the terminal searches for a network for all network systems supported by the terminal. However, the network system corresponding to the network covered by the first geographic location of the terminal may be only a part of all the network systems supported by the terminal, and if network search is performed on all the network systems supported by the terminal, a network system not supported by the first geographic location is also searched, so that much time is wasted in an intangible manner, the efficiency of searching the network is reduced, and the power consumption of the terminal is increased. At this time, in order to reduce useless search processes, the terminal may first acquire a first geographic location where the terminal is currently located, so as to determine a first network parameter corresponding to the first geographic location.
Here, the network system refers to a type of a network, and may be characterized by a network mode and a network frequency band. For example, a certain network system may be: TDD-LTE 1880-1900MHz, another network standard may be WCDMA 2100 MHz.
In practical application, the method for the terminal to obtain the current first geographic location of the terminal exists in the following two situations, but is not limited to the following two situations.
First, a first geographic location is actively obtained.
Illustratively, when the terminal detects that the terminal is in a no-network state, the terminal may acquire the first geographic location through a Global Positioning System (GPS).
Second, the first geographic location is obtained indirectly.
For example, after the terminal is in a no-network state, if the user wants the terminal to complete the network search process quickly, the user may actively input the current first geographic location of the terminal through the user input unit on the terminal, and at this time, the terminal may receive the first geographic location input by the user through the user input unit.
Then, in a specific implementation process, the foregoing S201 may include: receiving a first geographical position input by a user; alternatively, the first geographic location is obtained via GPS.
S202: matching a first network parameter corresponding to the first geographic position according to a pre-stored database;
here, the first network parameter corresponding to the first geographic location refers to a network mode and a network frequency band corresponding to a network covering the first geographic location.
In practical applications, the first network parameter may be a mode-band, such as { GSM 850MHz }, a mode-band, such as { GSM 850MHz/900MHz/1800MHz }, or a multi-mode-band, such as { WCDMA 2100MHz, TD-SCDMA 1880-1920MHz, CDMA 20001920-1935 MHz }, according to different numbers and types of networks covered by the first geographic location. Of course, other methods are also possible, such as { operator 1: TDD-LTE 1880-1900MHz/2320-2370MHz/2575-2635MHz, operator 2: TDD-LTE 2300-2320MHz/2555-2575MHz, operator 3: TDD-LTE2370 2390MHz/2635 2655MHz }. Here, the embodiments of the present invention are not particularly limited.
Specifically, in order to enable the terminal to perform network search more effectively, a database may be pre-stored on the terminal, where the database includes network parameters corresponding to networks covered by geographic locations of various regions of various countries, and when the terminal needs to perform network search, the terminal first obtains a first geographic location where the terminal is located, and then matches, through the pre-stored database, the first network parameter corresponding to the first geographic location based on the first geographic location.
In a specific implementation process, the manner of generating the database is also different according to different data sources of the network parameters corresponding to the geographic locations in the database. In practical applications, the database may be directly generated according to network data, or may be generated by learning a history result of a terminal searching for a network by using a machine learning method, or may be generated according to other manners, where embodiments of the present invention are not specifically limited herein.
In practical applications, in order to ensure the practicability and validity of the data stored in the database, the database may be updated in real time when the terminal has a network status, or may be updated according to the search result after the terminal searches for a network.
S203: selecting a second network parameter supported by the SIM card of the terminal from the first network parameters;
in practical applications, the types of the SIM cards may be standard SIM cards, Micro-SIM cards, Nano-SIM cards, and the like, and certainly, the types of the SIM cards may also be other types of subscriber Identity Module cards, such as Universal Subscriber Identity Module (USIM) cards, where the embodiments of the present invention are not specifically limited herein.
Specifically, the network mode and the network frequency supported by the SIM card installed on the terminal are different according to the attribute parameters of the SIM card, such as different operators and different types of SIM cards. Then, when the first geographic location covers multiple networks, in order to perform a network search more quickly, the second network parameter supported by the SIM card may be selected from the first network parameters corresponding to the first geographic location according to the attribute parameters of the SIM card.
In practical applications, the operator may be china mobile, china telecom, china unicom, etc., and the SIM card type may be a 4G card, a 3G card, a 2G card, etc.
For example, for a SIM card with a carrier of china mobile and a SIM card type of 4G, the network mode and the network frequency supported by the SIM card are {2G network: GSM 850MHz/900MHz/1800MHz/1900 MHz; 3G network: TD-SCDMA 1880-1920MHz/2010-2025 MHz; 4G network: TDD-LTE 1880-1900MHz/2320-2370MHz/2575-2635MHz }; for the SIM card whose carrier is china telecom and the SIM card type is 3G, the network mode and the network frequency supported by the SIM card are {2G network: CDMA 1 x; 3G network: CDMA 20001920-1935 MHz/2110-2125MHz }.
In a specific implementation process, in order to obtain the second network parameter, the terminal may first obtain an attribute parameter of the SIM card, determine an original network parameter supported by the SIM card according to the attribute parameter, and then determine an intersection part of the original network parameter and the first network parameter as the second network parameter supported by the SIM card. In practical applications, the second network parameter supported by the SIM card finally selected from the first network parameters may be the first network parameter itself or a part of the first network parameter, depending on the number of networks covered by the first geographical location and the type of the networks.
Exemplarily, assume that the first network parameter is { GSM 850MHz, TDD-LTE 2370-.
Illustratively, assume that the first network parameters are { GSM 850MHz, WCDMA 2100MHz, TD-SCDMA 1880-1920MHz, TDD-LTE2370-2390MHz }, and assume that the original network parameters supported by the SIM card are { GSM 850MHz, CDMA 20001920-1935 MHz, FDD-LTE: 1800MHz/2600MHz, so that the second network parameter supported by the SIM card can be selected to be { GSM 850MHz }.
In a specific implementation process, when the SIM card includes a first SIM card and a second SIM card, selecting a second network parameter supported by the SIM card of the terminal from the first network parameter includes: and respectively selecting a second network parameter supported by the first SIM card and a second network parameter supported by the second SIM card from the first network parameters.
Here, the second network parameters supported by the first SIM card and the second network parameters supported by the second SIM card may or may not be the same. Exemplarily, assuming that the first SIM card and the second SIM card are both china mobile 4G cards, the second network parameters supported by the first SIM card and the second network parameters supported by the second SIM card will be the same; assuming that the first SIM card is a 4G card for china telecommunications and the second SIM card is a 4G card for china mobile, the second network parameters supported by the first SIM card and the second network parameters supported by the second SIM card will be the same.
In practical application, when the terminal is a dual-card dual-standby all-network mobile phone, two SIM cards may be installed on the terminal, and at this time, the SIM cards include a first SIM card and a second SIM card, so that, in order to perform network search on each SIM card quickly, the terminal may select a second network parameter supported by the first SIM card from first network parameters corresponding to a first geographic location, then select a second network parameter supported by the second SIM card from the first network parameters corresponding to the first geographic location, and then, when performing network search, the terminal may search for a network available at the first geographic location by the first SIM card using the second network parameter supported by the first SIM card, and search for a network available at the first geographic location by the second SIM card using the second network parameter supported by the second SIM card.
S204: and performing network search by using the second network parameter.
Here, in order to avoid the problems caused by the full-mode full-frequency-segment blind search, such as time waste and low network searching efficiency, after the terminal determines the second network parameter supported by the SIM card of the terminal from the first network parameter corresponding to the first geographical location, the terminal may perform network search with pertinence using the second network parameter.
In a specific implementation process, when the terminal is processing other services, in order to perform network search quickly, the step S204 may further include: judging whether the terminal is processing other services; if the terminal is processing other services, determining the priority of other services and the network searching service through the current network state of the terminal and the service properties of other services based on the database; and when the priority of the network searching service is higher than the priorities of other services, stopping the processing of other services and using the second network parameter to search the network.
Here, the other services may be data connection or network update, and certainly may also be other services, such as network switching, system message issuing, and the like.
In practical applications, since when the terminal is processing other services, if a network search is to be performed, the other services and the network search may conflict, in order to perform the network search quickly, the terminal may first determine whether the terminal is processing other services, and when it is determined that the terminal is processing the other services, it may be determined whether to suspend processing the other services, perform the network search first, or continue processing the other services based on the priorities of the current service and the network search service. Specifically, when the priority of the network searching service is higher than the priorities of other services, the terminal can stop the processing of other services and preferentially use the second network parameter for network searching; otherwise, the terminal can process other services preferentially, and then, after processing other services, the terminal uses the second network parameter to perform network search.
Specifically, the priority of the system-level service is higher than that of the user-level service, such as the priority of the network searching service is higher than that of the data connection of the application software.
In other embodiments of the present invention, in order to search for a network when the terminal is in a non-service area, in order to ensure that the network can be quickly searched and reduce power consumption of the terminal, after S204, the method may further include: if the target network available for the terminal is not searched, determining the dormancy duration based on the current mobile state of the terminal, wherein the target network is a network which can be registered by the terminal; and when the dormancy duration is reached, using the second network parameter to perform network searching again.
In practical application, in order to ensure that a network is quickly searched and reduce the power consumption of a terminal, after the terminal does not search an available target network of the terminal, the terminal can determine a dormancy duration according to the current mobile state of the terminal, then, timing is started, and after the dormancy duration is reached, the terminal can perform network search again until the available target network is searched.
Here, in the embodiment of the present invention, in the network searching process, the terminal may determine the sleep duration in real time in consideration of the mobile state of the terminal, so that the sleep duration established by the terminal is reasonable, and efficient network searching can be implemented
In a specific implementation process, the step of determining the sleep duration based on the current moving state of the terminal may include: acquiring a second geographic position where the terminal is currently located; judging whether the position of the terminal changes or not based on the second geographical position and the first geographical position; if the position of the terminal is changed, setting the dormancy duration as a first value; otherwise, setting the sleep duration to be a second value, wherein the second value is N times of the first value, and N is an integer greater than or equal to 2.
In another embodiment of the present invention, in order to improve the user experience, the terminal may be preferentially registered to a better network, and after S204, the method may further include: and if the target networks available for at least two terminals are searched, performing network registration according to a preset rule based on the network attribute information corresponding to the target networks until the terminals are registered on the target networks.
Here, the network attribute information may be a network priority, or may also be a network signal quality, and of course, may also be other information, for example, the network priority is combined with the network signal quality, and the embodiment of the present invention is not particularly limited.
In the implementation process, the preset rule may include, but is not limited to, the following three cases according to different network attribute information.
First, network registration is performed in order of network priority from high to low.
Second, network registration is performed in the order of high to low network signal quality.
Thirdly, network registration is performed according to the sequence of the network priority from high to low, and then the network registration is performed according to the sequence of the network signal quality from high to low.
In addition, in practical application, when the terminal is a dual-card dual-standby all-network-communication mobile phone, the terminal can be provided with two SIM cards, a user can automatically set the main card and the auxiliary card according to needs or the terminal can set the main card and the auxiliary card by itself, when searching for a network, the priority of the main card is higher than that of the auxiliary card, and at this time, in order to improve user experience, the terminal can preferentially search for a network supported by the main card and then search for a network supported by the auxiliary card.
Then, when the SIM cards of the terminal include the first SIM card and the second SIM card, S204 may include: if the priority of the first SIM card is higher than that of the second SIM card, searching the network supported by the first SIM card by using the second network parameter supported by the first SIM card, and searching the network supported by the second SIM card by using the second network parameter supported by the second SIM card.
It should be noted that the priority of the SIM card may be set by the user according to the needs of the user, or may be set by the terminal system, and here, the embodiment of the present invention is not limited in particular.
At this point, the process of searching for a network is completed.
In the method for searching a network provided by this embodiment, when the terminal is in a no-network state, the terminal may match a first network parameter corresponding to a first geographic location where the terminal is currently located according to a pre-stored database, select a second network parameter supported by an SIM card of the terminal from the first network parameter, and then perform network search using the second network parameter. Therefore, the second network parameters are screened for the second time through the first geographic position and the SIM card, and then the network searching can be carried out in a targeted manner when the network searching is carried out through the screened second network parameters, wherein, as the network parameters which do not exist in the first geographic position are not required to be searched, and the network parameters which do not support the SIM card are not required to be searched, the useless searching process can be greatly reduced, and much time can be saved invisibly, thereby the problem caused by blind searching in a full-mode full-frequency band can be avoided, the network searching efficiency is improved, and the power consumption of the terminal is reduced.
Example two
Based on the foregoing embodiments, the present embodiment provides a method for searching a network, which is applied to the following scenarios: after the terminal searches for the network, but does not search for an available target network, the terminal may perform network searching again after a sleep time interval. In practical applications, in order to achieve both the network search speed and the reduction of power consumption of the terminal, the terminal dynamically sets the sleep duration according to its current moving state.

wherein the second value is N times the first value, and N is an integer greater than or equal to 2.

In the method for searching for a network provided by this embodiment, after the terminal does not search for an available target network, the terminal dynamically sets the sleep duration according to its current mobile state, and if the location of the terminal changes, a shorter sleep duration may be set, and conversely, if the location of the terminal does not change, a longer sleep duration may be set, so that, because the sleep duration determined by the mobile state of the terminal is used, the purpose of reducing the power consumption of the terminal may be achieved while the network search speed is ensured.
