In order to improve the network searching speed of the terminal, the terminal records the frequency point which is registered last time, and when the terminal is always in the same position area, the terminal searches the network according to the recorded frequency point and can quickly access the network supported by the corresponding position area.

If the current operator does not support a certain frequency band, the frequency band is not set in the frequency band list, so that the terminal does not search the network of the frequency band when searching the network. When the frequency band of the frequency band list does not accord with the frequency band of the actual network, the terminal cannot search the frequency band of the actual network, and further cannot access the actual network, so that the terminal is always in a non-service state.

All other embodiments that can be derived by one of ordinary skill in the art from the embodiments given herein are intended to be within the scope of the present disclosure.

It will be appreciated that the data so used may be interchanged under appropriate circumstances such that embodiments of the application may be practiced in sequences other than those illustrated or described herein, and that the terms "first," "second," and the like are generally used herein in a generic sense and do not limit the number of terms, e.g., the first term can be one or more than one. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/", and generally means that the former and latter related objects are in an "or" relationship.
The network searching method provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
Fig. 1 is a schematic flowchart of a network searching method according to an embodiment of the present application. Referring to fig. 1, the network searching method is applied to a first terminal, and includes:
and S110, obtaining the network frequency points of the historical connection, and searching the network according to the network frequency points of the historical connection.
The first terminal refers to an intelligent terminal with network searching capability, such as a mobile phone. The historically connected network frequency point refers to a frequency point at which the first terminal was connected to the network during one or more previous network searches. Illustratively, after the first terminal is disconnected from the network, network searching is performed, and when a certain frequency point is registered in the network, the frequency point is recorded as a historically connected network frequency point, so that if the actual network environment of the area where the first terminal is located covers the frequency point during the next network searching, the first terminal can be quickly accessed to the actual network based on the historically connected network frequency point.
Illustratively, after the first terminal is disconnected from the network, a network frequency point of historical connection is acquired, and network search is performed based on the network frequency point of historical connection. And if the actual network environment of the area where the first terminal is located covers the historically connected network frequency point, searching the actual network through the historically connected network frequency point, and further connecting the actual network. If the actual network environment of the area where the first terminal is located does not cover the historically connected network frequency point, the terminal cannot search the actual network through the historically connected network frequency point, and therefore cannot be connected with the actual network.
And S120, under the condition that the network is not searched on the basis of the network frequency points of the historical connection, performing network search according to the first frequency band and the second frequency band in the frequency band list of the first terminal, wherein the second frequency band is the frequency band added by the frequency band list updated in advance.
The frequency bands in the frequency band list are frequency bands for which the first terminal searches for the network through the driver program when the first terminal performs normal network searching, that is, the first terminal searches for the frequency bands in the frequency band list when performing normal network searching. The first frequency band of the frequency band list can be understood as the frequency band before the frequency band list is updated, and the second frequency band is the frequency band newly added after the frequency band list is updated. The first terminal of the embodiment increases the frequency bands in the frequency band list by itself to improve the network searching capability, and avoids that the first terminal is in a no-service state due to the fact that the frequency bands which cannot be covered by the actual network environment are searched.
The following is an exemplary illustration in a scenario. In the prior art, it is assumed that the current BAND list includes BAND1, where the BAND number is "1" for the BADN 1. When the first terminal leaves the area covered by the network supported by the BAND1 and reaches the area covered by the network supported by the BAND2, wherein BAND2 is the frequency BAND with the frequency BAND number of "2". Because the BAND list does not include the BAND2, the first terminal cannot initiate a search for the BAND2, and cannot access a network supported by the BAND2 without searching the BAND2, so that the first terminal falls into a dead loop of continuously searching the network-free BAND1, and the first terminal is in a service-free state for a long time, which affects user experience. Unless the first terminal obtains the frequency band covered by the actual network environment from the operator, the first terminal cannot judge the frequency band covered by the actual network environment by itself, that is, the terminal in the prior art does not have the capability of updating the frequency band list by itself, and only can modify the frequency band of the frequency band list by changing the driver in the form of upgrading the application package, which is more complicated to operate.
In an embodiment, the first terminal may search for a frequency band not included in the frequency band list for a specific period of time, and add the frequency band searched for the actual network to the frequency band list to update the frequency band list. The updated frequency band list comprises frequency bands covered by the actual network environment, and when the first terminal searches for the network next time, the first terminal can search for the actual network based on the frequency bands and connect with the actual network, so that the first terminal is prevented from falling into a long-time no-service state. Therefore, the second frequency band is also the frequency band of the actual network searched from the frequency bands not included in the frequency band list. For example, the first frequency BAND before the frequency BAND list is not updated is BAND1, the frequency BANDs that can be searched by the antenna of the first terminal include BAND1 and BAND2, and the frequency BAND covered by the actual network environment includes BAND2, so it can be confirmed that BAND2 is a frequency BAND not included in the frequency BAND list. The first terminal may search for the network of BAND2 for a certain period of time and, when the network of BAND2 is searched, add BAND2 as the second BAND to the BAND list. The updated frequency BAND list comprises BAND1 and BAND2, and when the first terminal moves to an area covered by a network supported by only BAND2, the first terminal can search for an actual network and access the actual network through the BAND2 in the frequency BAND list.
Fig. 2 is a flowchart for updating a frequency band list according to a frequency band search according to an embodiment of the present application. As shown in fig. 2, the step of updating the frequency band list according to the frequency band search specifically includes steps S210 to S220:
s210, searching a third frequency band under the condition that a preset condition is met, wherein the frequency band list does not include the third frequency band.
The third frequency band is a frequency band not included in the frequency band list, and the preset condition is a condition that is satisfied by the first terminal searching for the third frequency band. Exemplarily, when the first terminal performs a normal network search based on the frequency band list, it is impossible to search for a network of a frequency band that is not included in the frequency band list, so this embodiment proposes that, in a case that a preset condition is satisfied, the terminal performs a special network search to search for a network of a frequency band that is not included in the frequency band list, and then searches for a frequency band covered by an actual network environment and adds the frequency band to the frequency band list, thereby implementing a self-dynamic update of the frequency band list by the terminal.
In this embodiment, the first frequency band is filtered out from all frequency bands that the antenna of the first terminal can search, resulting in a third frequency band. For example, if the first frequency BAND is BAND1, and all frequency BANDs that the antenna of the first terminal can search include BAND1 and BAND2, it may be determined that the third frequency BAND is BAND 2.
In an embodiment, the third frequency band is searched when the current time is within a preset time period and all the applications of the first terminal stop running. The preset time period is set according to the sleeping time of the user. Illustratively, the first terminal disconnects the network when performing special network searching so that the terminal enters a no-service state, and the first terminal can perform special network searching to update the frequency band list at night when the user sleeps and various application programs do not use network data, so that the influence of the special network searching on the normal use of the terminal is avoided. When the first terminal detects that the current time point is at the sleep time of the user and no application program runs in the background, the first terminal conducts special network searching to update the frequency band list.
In another embodiment, the third frequency band is searched when the duration of the first terminal in the network service absence state is greater than or equal to a preset duration. The preset time duration is set according to actual requirements and is generally longer than the time duration required by normal network searching. Illustratively, the first terminal searches for a network of a frequency band in the frequency band list when performing normal network search, and if the frequency band covered by the actual network environment where the first terminal is currently located does not match the frequency band in the frequency band list, the first terminal cannot search for the frequency band covered by the actual network, and further cannot access the network and remains in a no-service state. If the user is always in the same area, the first terminal waits until the user sleeps, the first terminal keeps in a no-service state for a long time, and user experience is poor. Therefore, in this embodiment, when the duration of the first terminal being maintained in the no-service state is greater than or equal to a certain duration, the terminal performs a special network search to update the frequency band list, so as to avoid that the first terminal is in the no-service state for a long time, and improve user experience.
And S220, under the condition that the third frequency band is the available frequency band, adding the third frequency band as the second frequency band to the frequency band list.
For example, if the third frequency band is an available frequency band in which a network can be searched, it indicates that the frequency band covered by the actual network environment includes a frequency band that cannot be searched by the first terminal when the first terminal normally searches for a network, and therefore, the third frequency band may be added to the frequency band list, so that the first terminal can always search for the network of the third frequency band when the first terminal is in the network coverage area of the third frequency band and connect to the network. For example, when the third BAND is BAND2, the first terminal searches for a network of BAND2, and if the actual network environment where the terminal is located covers BAND2, the terminal searches for a network of BAND2 and adds BAND2 as the second BAND to the BAND list, and the updated BAND list includes BAND1 and BAND 2. In this embodiment, by updating the frequency band list, the frequency band covered by the actual network environment can be added to the frequency band list, so that the frequency band list conforms to the frequency band covered by the actual network environment, and it is avoided that the first terminal cannot search the actual network in the normal network search.
In an embodiment, fig. 3 is a schematic diagram of network coverage areas supported by frequency bands according to an embodiment of the present disclosure. As shown in fig. 3, the first circular area 11 is an area covered by a network supported by BAND1, the second circular area 12 is an area covered by a network supported by BAND2, and the intersection area 13 of the first circular area and the second circular area is an area covered by both a network supported by BAND2 and a network supported by BAND 1. Assuming that the first terminal 14 is located in the intersection area 13 at the time of the user's sleep, the first terminal determines that the third BAND is BAND2 when updating the BAND list. The first terminal searches a network based on BAND2, and adds BAND2 as a second BAND to the BAND list after searching the network, such that the updated BAND list includes BAND1 and BAND 2. After the first terminal moves from the intersection area 13 to the second circular area 12 during the day, it can connect to the actual network of the second circular area based on BAND2 since the BAND list contains BAND 2. In the embodiment, the frequency bands covered by the actual network environment are learned in advance so as to be added to the frequency band list in time, and the condition that the terminal is in a long-time non-service state due to untimely updating of the frequency band list is avoided.
In another embodiment, fig. 4 is a second schematic diagram of network coverage areas supported by various frequency bands according to the embodiment of the present application. As shown in fig. 4, assuming that the first terminal 14 is located in the first circular area 13 at the time of the user's sleep, the updated BAND list is BAND 1. When the BAND list does not include the BAND2 after the first terminal moves from the first circular area 13 to the second circular area 12 during the day, the first terminal continuously searches for the network of the BAND1 and falls into a no-service state. And when the duration of the first terminal in the no-service state reaches the preset duration, the first terminal performs special network searching to update the frequency band list. When the frequency BAND list is updated, the terminal determines that the third frequency BAND is BAND2, and searches the network based on BAND 2. After searching the network of the BAND2, the terminal adds the BAND2 as a second frequency BAND to the frequency BAND list, and the updated frequency BAND list comprises BAND1 and BAND 2. After the frequency BAND list is updated, the first terminal performs normal network searching based on the frequency BAND list, and can be connected to the actual network of the second circular area through the BAND 2. In this embodiment, when the first terminal is limited and cannot search the frequency band covered by the actual network environment, the frequency band covered by the actual network environment is added to the frequency band list through the special network search and the frequency band list is updated in time, so that the first terminal can be connected to the actual network when performing normal search based on the updated frequency band list, and the terminal is prevented from falling into a long-time no-service state.
In an embodiment, after the second frequency band is added to the frequency band list, the first frequency point of the network is searched in the second frequency band for network connection, and the first frequency point is updated to the network frequency point of the historical connection. Each frequency band comprises a plurality of frequency points, the network for searching the frequency band is a network for sequentially registering each frequency point in the frequency band, when a certain frequency point is registered in the network, the terminal is determined to search the network of the corresponding frequency band, and therefore the first frequency point is the frequency point registered in the second frequency band to the actual network. In the scenario shown in fig. 4, when the first terminal triggers the frequency BAND list to be updated due to a long-time network outage, the first terminal searches for the network of the BAND2 and registers in the network through the intermediate frequency point of the BAND 2. The terminal can connect the network to which the intermediate frequency point of the BAND2 is registered, normal network searching is not required, network searching time spent in normal network searching is saved, and network searching speed of the terminal is improved. Further, the intermediate frequency point of the BAND2 is recorded as a network frequency point of historical connection, if the terminal is always located in the second circular area, network search can be performed through the intermediate frequency point of the BAND2 after the network of the first terminal is disconnected next time, and then the actual network of the second circular area is connected quickly, so that the network searching speed of the terminal is improved.
In an embodiment, the first terminal may update the frequency band list through a special network search, and may also receive a frequency band sent by another terminal and add the frequency band to the frequency band list. Fig. 5 is a flowchart for updating a frequency band list according to a shared frequency band according to an embodiment of the present application. As shown in fig. 5, the step of updating the frequency band list according to the common frequency band specifically includes steps S310 to S320:
and S310, establishing connection with the second terminal, and receiving fourth frequency band information sent by the second terminal.
And S320, adding the fourth frequency band serving as the second frequency band to the frequency band list.
The second terminal is other intelligent terminal equipment which can establish communication connection with the first terminal, and the second terminal can also update the frequency band list of the second terminal based on special network searching. The fourth frequency band is the second frequency band after the frequency band list of the second terminal is updated. Exemplarily, after the first terminal establishes a communication connection with the second terminal, for example, after the first terminal is connected with the second terminal through wifi or bluetooth, the second terminal sends the fourth frequency band to the first terminal. And after receiving the fourth frequency band, the first terminal determines that the fourth frequency band is a frequency band covered by the actual network environment searched by the second terminal through special network searching, and then adds the fourth frequency band serving as the second frequency band to the self frequency band list. At the moment, the first terminal can determine the frequency band covered by the actual network environment without special network searching, so that the corresponding frequency band list is updated, and the updating speed of the frequency band list of the first terminal is increased.
In this embodiment, after the first terminal performs the special network search to update the frequency band list of the first terminal, the first terminal may also send the frequency band currently searched to be covered by the actual network environment to the third terminal that establishes the communication connection, so that the third terminal adds the frequency band sent by the first terminal to the frequency band list of the first terminal. And the third terminal refers to other intelligent terminals of which the first terminal shares the second frequency band through communication connection. Exemplarily, the first terminal establishes a communication connection with the third terminal, and detects whether the third terminal supports frequency band sharing; and under the condition that the third terminal supports frequency band sharing, the first terminal sends the second frequency band to the third terminal so that the third terminal adds the second frequency band to the own frequency band list. If the third terminal supports frequency band sharing, the third terminal is indicated to have the capability of updating the frequency band list based on the second frequency band shared by the first terminal, so that the third terminal can add the second frequency band to the frequency band list after the first terminal shares the second frequency band to the third terminal; on the contrary, if the third terminal does not support frequency band sharing, it indicates that the third terminal does not have the capability of updating the frequency band list based on the second frequency band shared by the first terminal, and therefore, after the first terminal shares the second frequency band to the third terminal, the third terminal cannot update the frequency band list.
In an embodiment, the first terminal determines whether the third terminal supports frequency band sharing according to a result returned by the third terminal by sending a sharing detection instruction to the third terminal. The sharing detection instruction is an instruction for detecting whether the third terminal supports frequency band sharing. Illustratively, the first terminal sends the sharing detection instruction to the third terminal, and the third terminal confirms whether the frequency band list thereof can be modified after receiving the sharing detection instruction. And if the third terminal confirms that the self frequency band list can be modified, determining that the third terminal supports the frequency band sharing, and sending a detection result of supporting the frequency band sharing to the first terminal. On the contrary, if the third terminal confirms that the self frequency band list cannot be modified, the third terminal determines that the third terminal does not support frequency band sharing, and sends a detection result that the frequency band sharing is not supported to the first terminal. Further, when the first terminal receives a detection result of supporting frequency band sharing sent by the third terminal, it is determined that the third terminal supports frequency band sharing, and the second frequency band is sent to the third terminal. And when the first terminal receives a detection result which is sent by the third terminal and does not support frequency band sharing, and the third terminal does not support frequency band sharing, the second frequency band is not sent to the third terminal.
It should be noted that the process of the second terminal sharing the frequency band with the first terminal is the same as the process of the first terminal sharing the frequency band with the third terminal.
In summary, in the network searching method provided in this embodiment, a frequency band covered by an actual network environment is searched by performing a special network search on a frequency band not included in the frequency band list of the first terminal, and the frequency band covered by the actual network environment is added to the frequency band list, so as to update the frequency band list. Through the technical means, the frequency band list of the first terminal comprises the frequency bands supported by an operator and the newly-added frequency bands covered by the actual network environment, and when the first terminal searches for the network based on the frequency bands in the frequency band list, the actual network can be searched through the frequency bands covered by the actual network environment, so that the problem that the frequency band list lacks the frequency bands of the actual network and the terminal has a no-service state is avoided, and the reliability of the network searching function is improved. In addition, the first terminal receives the frequency band covered by the actual network environment shared by other terminals, and adds the frequency band of the actual network to the frequency band list of the first terminal, so that the first terminal can update the corresponding frequency band list without special network searching, the operation process of updating the frequency band list by the first terminal is simplified, and the updating efficiency of the frequency band list of the first terminal is improved.
It should be noted that, in the network search method provided in the embodiment of the present application, the execution main body may be a network search apparatus, or a control module in the network search apparatus for executing the network search method. The network search device provided by the embodiment of the present application is described by taking an example of a method for executing a network search by a network search device.
