The network 104 serves as a medium for providing communication links between the terminal devices 101, 102, 103 and the server 105. Network 104 may include various connection types, such as wired, wireless communication links, or fiber optic cables, to name a few.
It should be understood that the number of terminal devices, networks, and servers in fig. 1 is merely illustrative. There may be any number of terminal devices, networks, and servers, as desired for implementation. For example, server 105 may be a server cluster comprised of multiple servers, or the like.

For example, when a user acquires a scanning instruction through the terminal device 103 (which may also be the terminal device 101 or 102), acquiring a first frequency point set for a target area; when a first frequency point database is detected to exist, determining whether the communication environment of the target area changes or not based on the first frequency point set and the first frequency point database, wherein the first frequency point database is a database established based on the last scanning of the frequency points of the target area; and when the communication environment of the target area is determined not to be changed, selecting a target frequency point based on the first frequency point database.

The application also provides a method, a device, a target terminal and a medium for selecting the frequency points.
Fig. 2 schematically shows a flow chart of a method for selecting a frequency point according to an embodiment of the present application. As shown in fig. 2, the method is applied to a mobile terminal, and includes:
s101, when a scanning instruction is acquired, acquiring a first frequency point set of a target area.
It should be noted that, in the present application, a device for acquiring the first frequency point set of the target area is not specifically limited, and for example, the device may be an intelligent device, and may also be a server. The intelligent device may be a PC (Personal Computer), or a smart phone, a tablet Computer, an e-book reader, or an MP3(Moving Picture expert group audio layer III) frequency point selector. MP4(moving Picture expert group Audio Layer IV, moving Picture experts compression standard Audio Layer 4) frequency point selector, or portable terminal equipment such as portable computer with display function.
The first frequency point set in the present application may be a frequency point corresponding to a GSM-based system. Further, Global System for Mobile Communications GSM (Global System for Mobile Communications GSM) is a digital Mobile Communications standard that is set forth by the european telecommunication standards institute ETSI. Its air interface uses time division multiple access technology. Both signaling and voice channels are digital, and thus GSM is considered a second generation (2G) mobile telephone system. The GSM network system architecture is shown in fig. 3, and includes an MS (Mobile Station), a BTS (Base Transceiver Station), a BSC (Base Station Controller), and an MSC (Mobile Switching Center). The BTS and BSC are called BSS (Base Station System), the BTS and BSC are connected by Abis interface for realizing wireless access function, and circuit domain data is transmitted between MS and MSC. MSC is core of GSM network, processing signaling from MS and base station subsystem in controlled area, realizing functions of mobility management, call exchange and charging collection, etc, BSC and MSC are connected by A interface. The MSC is mainly used for interfacing with an external network, and implementing signaling and traffic switching between the local mobile network and other networks.
In addition, in the present application, the number of frequency points in the first frequency point set is not limited. The frequency point is a number for a fixed frequency in the GSM system. In the GSM network, frequency points are used to designate the transmission frequency of the transceiver group instead of frequencies. For example, the following steps: a carrier is assigned a frequency point of 3, that is to say that the carrier will receive an upstream signal with a frequency of 890.4MHz and transmit a signal at a frequency of 935.4 MHz.
S102, when the first frequency point database is detected to exist, whether the communication environment of the target area changes or not is determined based on the first frequency point set and the first frequency point database, wherein the first frequency point database is a database established when the frequency points of the target area are scanned last time.
Further, after the first frequency point set is obtained, each frequency point in the first frequency point set can be matched with each frequency point in the first frequency point database, and whether the communication environment of the target area changes or not is determined according to a matching result. It should be noted that the first frequency point database in the present application is a database established when the frequency point set of the target area is obtained for the first time.
It can be understood that, if each frequency point in the first frequency point set is unsuccessfully matched with each frequency point in the first frequency point database, the communication environment of the target area changes. And if each frequency point in the first frequency point set is successfully matched with each frequency point in the first frequency point database, the communication environment is not changed.
And S103, when the communication environment of the target area is determined not to change, selecting the target frequency point based on the first frequency point database.
When the communication environment of the target area is determined not to change, the target frequency point required by the scanning can be selected based on each frequency point in the first frequency point database obtained by scanning the target area before. It can be understood that, in the related art, when the mobile terminal acquires the frequency point corresponding to the GSM cell, because the frequency band of the GSM and the frequency band of other access modes overlap more seriously in the actual network deployment, many GSM frequency point signals are very strong but are not the GSM cell in fact. Therefore, the method and the device can be based on the frequency point database which is scanned and stored before when the target frequency point is scanned. And selecting the target frequency point in a targeted manner.
In the application, after the first frequency point set of the target area is acquired, whether the communication environment of the target area changes or not can be determined based on the first frequency point set and a preset first frequency point database established when the frequency point of the target area is scanned last time, and when the communication environment of the target area is determined not to change, the target frequency point is selected based on the first frequency point database. By applying the technical scheme of the application, when the GSM target frequency point of the target area is scanned at this time, the target frequency point can be selected in a targeted manner based on the database of the frequency points stored in the historical scanning record of the area. And then the problem of device resource consumption caused by the fact that a target frequency point can be found only by scanning a large number of frequency points in the related technology can be avoided.
Optionally, in a possible implementation manner of the present application, in the application S103 (selecting the target frequency point based on the first frequency point database), the following two cases may be included:
in the first case:
acquiring corresponding first frequency points in a first frequency point database;
acquiring frequency point parameters corresponding to each first frequency point, wherein the frequency point parameters comprise at least one of signal intensity, Base Station Identification Codes (BSIC), System Information (SI) and cell identification codes;
and selecting a target frequency point based on the frequency point parameters corresponding to the first frequency points.
Further, when the communication environment of the target area is determined not to change, the current appropriate target frequency point can be selected from the frequency point parameters corresponding to the first frequency points in the first frequency point database. It should be noted that the frequency point parameters in this application at least include any one or more of the following parameters:
signal strength parameter, Base Station Identity Code (BSIC) parameter, system message (SI) parameter and cell identity code parameter.
Optionally, the signal strength parameter in the present application may define an interference level according to the interference strength received in the downlink measurement process, and obtain the signal strength parameter corresponding to the frequency point according to the interference level. It can be understood that the lower the interference level corresponding to the frequency point is, the higher the signal strength parameter corresponding to the frequency point is. Further, the BSIC parameter in the present application is a Base Station Identity Code (BSIC). In the GSM system, each BTS (base station) is assigned a color code (BSIC). The mobile station can distinguish different cells having the same BCCH with the help of BSIC. The BSIC may be used to participate in the coding process of the access system message, measure the BCCH signal of the neighboring cell and report the measurement result to the network, and so on. Further, the SI parameter in this application is referred to as a system message, i.e. a message broadcasted over the radio interface, and many messages are usually required from the network in order to obtain or provide various services. The system messages can be divided into 12 types: TYPE1, 2bis, 2ter, 3, 4, 5bis, 5ter, 6, 7, 8. And under the GSM system, a cell global identity parameter for identifying the cell.
Furthermore, in order to find a suitable target frequency point from the plurality of frequency points. The method and the device can read the parameter information of each frequency point in the first frequency point database in sequence. And according to at least one of the plurality of parameter information mentioned above. And determining the corresponding target frequency point. For example, when the frequency points of the chinese mobile operator need to be acquired in the scanning, the operator to which the frequency point belongs can be determined based on the cell identifier corresponding to each frequency point. And then selecting the target frequency point.
As can be appreciated, each of the first frequency bins exists. That is, when the device scans the target area for the first time, the obtained frequency point can be scanned and the frequency point corresponding to the frequency point parameter can be read. After the device acquires the multiple frequency points for the first time, the multiple frequency points can be stored in the first frequency point database. Therefore, when the frequency points are scanned in the target area subsequently, the frequency points stored in the first frequency point database can be directly utilized to select the appropriate target frequency points.
In the second case:
when the first frequency point database does not contain the target frequency points based on the frequency point parameters corresponding to the first frequency points, acquiring a third frequency point set, wherein the third frequency point set is a frequency point set obtained based on the first frequency point set and a second frequency point set, and the second frequency point set is a frequency point set stored in the second frequency point database;
acquiring frequency point parameters corresponding to all frequency points in a third frequency point set;
and selecting a target frequency point based on the frequency point parameters corresponding to the frequency points in the third frequency point set.
It can be understood that, in this scanning, the required target frequency point may or may not be included in the first frequency point database. Further, when it is determined that the first frequency point database does not contain the target frequency point based on the frequency point parameters corresponding to the first frequency points, the target frequency point can be selected by using the third frequency point set. It should be noted that the third frequency point set in this application is a frequency point set obtained based on the first frequency point set and the second frequency point set, and the second frequency point set is a frequency point set stored in the second frequency point database.
Optionally, in the present application, based on the frequency point parameters corresponding to each frequency point in the third frequency point set, before selecting a target frequency point, the following steps need to be further implemented:
and establishing a second frequency point database, wherein the second frequency point database is a database generated based on the first frequency point database.
Further, in the present application, before selecting a target frequency point by using a third frequency point set, a first frequency point database and a second frequency point database need to be established first. In the present application, the second frequency point database is a database generated based on the first frequency point database.
Furthermore, in the process of establishing the first frequency point database, the method can be obtained through the following steps:
when the communication environment of a target area is determined to be changed based on a preset mode, acquiring a target frequency point set of the target area;
acquiring frequency point parameters corresponding to each frequency point in a target frequency point set, and detecting a set of frequency points meeting a first condition in the frequency point parameters corresponding to each frequency point;
and establishing a first frequency point database based on the frequency points of which the frequency point parameters meet the first condition in the target frequency point set.
Further, when the device determines that the communication environment of the current target area changes, the target frequency point set for the target area can be acquired. And after the target frequency point set is obtained, the frequency point parameters corresponding to the frequency points contained in the target frequency point set are sequentially read. And storing the frequency points meeting the first condition in a first frequency point database.
It can be understood that the frequency points corresponding to the suitable cells required by the device should be frequency points that can be read by the signal strength parameter, the base station identity code BSIC parameter, the system message SI parameter, and the cell identity code parameter. Therefore, whether the obtained frequency points meet the requirements of the user or not can be determined based on the number (namely, the first condition) of the obtained frequency points including the plurality of frequency points. And if so, storing the frequency point data into a first frequency point database.
For example, taking the first condition as an example that all frequency point parameters are included, in the present application, when a target area is scanned for the last time, a target frequency point set including 5 frequency points is obtained. Further, the device will sequentially read the frequency point parameters corresponding to the 5 frequency points. And obtaining: a frequency point containing only signal strength parameters in frequency point 1, a frequency point containing only BSIC parameters in frequency point 2, a frequency point containing only SI parameters in frequency point 3, a frequency point containing only cell identification code parameters in frequency point 4, and a frequency point containing signal strength parameters, base station identification code BSIC parameters, system information SI parameters, and cell identification code parameters in frequency point 5. And comparing the frequency point parameters corresponding to the 5 frequency points with the first condition respectively to obtain the frequency point parameters corresponding to the frequency point 5 as the frequency points meeting the first condition. Therefore, the frequency point corresponding to the frequency point 5 can be stored in the first frequency point database.
It should be noted that the first condition is not specifically limited in this application, and may be, for example, all frequency point parameters or some frequency point parameters.
Further optionally, after detecting the set of frequency points meeting the first condition in the frequency point parameters corresponding to the frequency points, the method further includes:
and establishing a second frequency point database based on the frequency points of which the frequency point parameters do not meet the first condition in the target frequency point set.
It can be understood that the frequency point corresponding to the suitable cell required by the device should be a frequency point whose frequency point parameters can be read. Therefore, whether the obtained frequency points meet the requirements of the user or not can be determined based on the number (namely, the first condition) of the obtained frequency points including the plurality of frequency points. And if so, storing the frequency point data into a first frequency point database. And if not, storing the frequency point data into a second frequency point database.
Similarly, taking the first condition as an example that all frequency point parameters are included, in the present application, when a target area is scanned for the last time, a target frequency point set including 5 frequency points is obtained. Further, the device will sequentially read the frequency point parameters corresponding to the 5 frequency points. And obtaining: a frequency point containing only signal strength parameters in frequency point 1, a frequency point containing only BSIC parameters in frequency point 2, a frequency point containing only SI parameters in frequency point 3, a frequency point containing only cell identification code parameters in frequency point 4, and a frequency point containing signal strength parameters, base station identification code BSIC parameters, system information SI parameters, and cell identification code parameters in frequency point 5. And comparing the frequency point parameters corresponding to the 5 frequency points with the first condition respectively to obtain the frequency point parameters corresponding to the frequency point 5 as the frequency points meeting the first condition, and the rest frequency points as the frequency points not meeting the first condition. Therefore, the frequency points corresponding to the frequency point 1, the frequency point 2, the frequency point 3 and the frequency point 4 can be stored in the second frequency point database.
Optionally, in a possible implementation manner of the present application, before selecting a target frequency point by using the third frequency point set, the following steps may be further implemented:
acquiring each second frequency point corresponding to the first frequency point set and each third frequency point corresponding to the second frequency point set;
and eliminating the frequency points which are repeated with the third frequency point in each second frequency point corresponding to the first frequency point set to obtain a third frequency point set.
Further, the second frequency point set in the present application is a frequency point set stored in the second frequency point database. And when the frequency point contained in the second frequency point database is the frequency point which does not meet the first condition and is recorded when the target area is scanned for the last time. Therefore, in the process of obtaining the target frequency point this time, each third frequency point corresponding to the second frequency point set should be removed from each second frequency point corresponding to the first frequency point set. Thereby obtaining a third frequency point set after the third frequency point is eliminated. And selecting the target frequency point according to the third frequency point set.
It can be understood that the first frequency point set and the second frequency point set are both frequency point sets scanned based on the same position (i.e. the target area). Therefore, the two frequency point sets should include the frequency points which exist repeatedly. Therefore, the third frequency point set can be obtained based on the frequency points which are repeated with the third frequency point in the second frequency points corresponding to the first frequency point set.
Take the example that the first frequency point set includes 5 second frequency points (frequency point 1, frequency point 2, frequency point 3, frequency point 4, and frequency point 5, respectively), and the second frequency point set includes 3 third frequency points (frequency point 1, frequency point 2, frequency point 3, respectively): in this application, since the second frequency point set stored in the second frequency point database is a set of frequency points (i.e., frequency point 1, frequency point 2, and frequency point 3) that do not meet the first condition when the target area is scanned for the last time. When the target area is scanned, a frequency point set (i.e., frequency point 1, frequency point 2, frequency point 3, frequency point 4, and frequency point 5) including frequency point 1, frequency point 2, and frequency point 3 is also scanned. In order to avoid the defect that the device resources are consumed because the three frequency points are found to be the frequency points which do not meet the conditions after the frequency point parameters corresponding to the frequency point 1, the frequency point 2 and the frequency point 3 are read in the same time. The frequency points contained in the second channel set can be directly removed from the first frequency point set. And obtain the third frequency point set which only contains the frequency point 4 and the frequency point 5 after the removal. So that the target frequency point is selected according to the third frequency point set only containing the frequency point 4 and the frequency point 5.
Still further optionally, in the process of selecting the target frequency point by using the third frequency point set, the method can further obtain the target frequency point by the following steps:
acquiring fourth frequency points corresponding to the third frequency point set;
acquiring frequency point parameters corresponding to the fourth frequency points;
and selecting a target frequency point based on the frequency point parameters corresponding to the fourth frequency points.
Furthermore, in order to find a suitable target frequency point from the plurality of frequency points included in the third frequency point set. The method and the device can also read the frequency point parameters of each fourth frequency point in the third frequency point set in sequence. And according to at least one of the plurality of frequency point parameter information mentioned above. And determining the corresponding target frequency point. For example, when the frequency points of the operator of china unicom need to be acquired in the scanning, the operator to which the scanning belongs can be determined based on the cell identification code corresponding to each fourth frequency point. And then selecting the target frequency point.
As can be understood, the set of third frequency points corresponds to the fourth frequency points. That is, when the removing device scans the target area for the first time, the obtained frequency points can be scanned, and the frequency points corresponding to the frequency point parameters can be read (that is, the frequency points are not eliminated to be stored in the second frequency point database).
Optionally, in a possible implementation manner of the present application, in this application S102 (determining whether a communication environment of a target area changes based on a first frequency point set and a first frequency point database), a method for selecting a frequency point is further included, as shown in fig. 4, including:
s201, acquiring a first frequency point set of a target area.
And S202, acquiring corresponding fifth frequency points in the first frequency point set and acquiring corresponding sixth frequency points in the first frequency point database.
And S203, when the coincidence degree of each fifth frequency point and each sixth frequency point is determined to reach a preset threshold value, determining that the communication environment of the target area is not changed.
Optionally, in the present application, when determining whether the communication environment of the target area changes, the determination may be performed by acquiring each fifth frequency point included in the first frequency point set and each sixth frequency point included in the first frequency point database. It can be understood that if the contact ratio between each frequency point in the frequency point set (first frequency point set) obtained by the scanning and each frequency point in the frequency point set (first frequency point database) obtained by the scanning last time reaches a preset threshold, it can be determined that the frequency points obtained by the scanning twice are the same. I.e., the target area is considered to be an area in which the communication environment has not changed.
The preset threshold is not specifically limited in the present application, and may be, for example, 100% or 90%.
Take the first frequency point set containing 5 fifth frequency points (frequency point 1, frequency point 2, frequency point 3, frequency point 4, and frequency point 5, respectively), and the first frequency point database also containing 5 sixth frequency points (frequency point 1, frequency point 2, frequency point 3, frequency point 4, and frequency point 5, respectively) as an example: after the 5 fifth frequency points and the 5 sixth frequency points are obtained, the 5 fifth frequency points can be respectively matched with the 5 sixth frequency points, and when the 5 fifth frequency points and the sixth frequency points are obtained to be overlapped, the overlapping degree of the 5 fifth frequency points and the sixth frequency points is judged to be 100%. And then determining that the target area is an area with unchanged communication environment.
Optionally, in the present application, in the process of determining whether the target area is a communication environment, the following method may be further used:
acquiring each frequency point in a first frequency point set;
selecting the frequency points with the signal intensity within a preset range from the frequency points in each first frequency point set to obtain a fourth frequency point set;
in the application, in order to avoid the problem that the equipment resource consumption is large due to the existence of too many frequency points in the first frequency point set, the frequency points with the signal intensity within the preset range can be selected, and then the corresponding fourth frequency point set is obtained.
It should be noted that the preset range is not specifically limited in the present application, and for example, the signal strength may be greater than-100 dBm, or may be greater than-50 dBm.
Acquiring the signal intensity corresponding to each seventh frequency point in the fourth frequency point set, and acquiring the signal intensity corresponding to each eighth frequency point in the first frequency point database;
comparing each seventh frequency point with each eighth frequency point one by one based on the magnitude of the signal intensity to generate a comparison result;
and determining the target area as an area where the communication environment is not changed based on the comparison result.
In the application, whether the target area is an area with a changed communication environment can be determined by determining whether the coincidence degree of each fifth frequency point corresponding to the first frequency point set and each sixth frequency point corresponding to the first frequency point database reaches a preset threshold value or not, and determining whether the target area is an area with a changed communication environment or not by determining the signal intensity of the target area and the signal intensity of the target area.
Further, the signal strength corresponding to each seventh frequency point in the fourth frequency point set and the signal strength corresponding to each eighth frequency point in the first frequency point database can be obtained. And determining whether the regions of the secondary scanning are the same region based on whether the difference value of the signal intensity of the two regions is smaller than a preset threshold value. For example, for each frequency point which meets the first condition and has a signal stronger than-100 dBm in the first frequency point database, if the full-frequency scanning (that is, the frequency points in the first frequency point set) can be scanned, and the full-frequency scanning finds that the signal intensity of the frequency point is different from the signal intensity recorded by each frequency point in the first frequency point database by no more than 10dB, the secondary scanning is considered as the same location, otherwise, the secondary scanning is not considered as the same location.
And S204, when the communication environment of the target area is not changed, selecting the target frequency point based on the first frequency point database.
S205, when the communication environment of the target area is determined to be changed, a first frequency point database is established based on each frequency point in the first frequency point set.
It can be understood that when it is determined that the communication environment of the target area scanned this time changes, the first frequency point database may be established based on each frequency point in the first frequency point set. Therefore, when the area is scanned again, the target frequency point can be obtained based on the first frequency point database established in the area.
Further, with reference to fig. 5, as shown in fig. 5, in the present application, first, when it is determined that the communication environment of the target area changes based on a preset manner, a target frequency point set of the target area may be obtained. And reading corresponding frequency point parameters of all frequency points in the target frequency point set of the region. The frequency point parameters may include at least one of a signal strength parameter, a base station identity code BSIC parameter, a system message S I parameter, and a cell identity code parameter of a corresponding frequency point. And then matching the frequency point parameters corresponding to the frequency points with a preset first condition to obtain a first frequency point database containing a frequency point set with all frequency point parameters meeting the first condition and a second frequency point database containing a frequency point set with all frequency point parameters not meeting the first condition. Further, when a certain region is scanned this time, a first frequency point set of the region may be obtained first, and whether the region has been subjected to frequency spot scanning is determined according to the overlap ratio of each frequency point in the first frequency point set and each frequency point in the first frequency point database. If the frequency point scanning is not performed once, the scanning area is considered to be the first scanning area.
Furthermore, when it is determined that the communication environment of the target area changes, a first frequency point database may be established based on each frequency point in the first frequency point set. The establishing step is the same as the above, and is not described herein again.
Still further, when it is determined that the communication environment of the target area does not change, whether the target frequency point is included in the first frequency point database may be determined based on the frequency point parameter corresponding to each first frequency point. And if so, selecting the target frequency point based on the frequency point parameters corresponding to the first frequency points. If not, all the second frequency points corresponding to the first frequency point set and all the third frequency points corresponding to the second frequency point set need to be obtained first, and after the frequency points which are repeated with the third frequency points in all the second frequency points corresponding to the first frequency point set are eliminated, a third frequency point set is obtained. And selecting the target frequency point by utilizing each frequency point in the third frequency point set subsequently.
In the method and the device, after the first frequency point set of the target area is obtained, whether the communication environment of the target area changes or not can be determined based on the first frequency point set and a preset first frequency point database established when the frequency points of the target area are scanned for the last time, and when the communication environment of the target area is determined not to change, the target frequency points are selected based on the first frequency point database. By applying the technical scheme of the application, when the GSM target frequency point of the target area is scanned at this time, the target frequency point can be selected in a targeted manner based on the database of the frequency points stored in the historical scanning record of the area. And then the problem of device resource consumption caused by the fact that a target frequency point can be found only by scanning a large number of frequency points in the related technology can be avoided.
