However, the early-built base stations capable of providing the low-level network standard are not configured with the information of the base station corresponding to the high-level network standard, for example, the early-built 2G base station is not generally configured with a 4G or 5G base station as a neighboring cell. When the terminal is accessed to the base station corresponding to the low-level network standard, the base station corresponding to the low-level network standard cannot indicate that the terminal is switched back to the high-level network standard, so that the terminal is always in the low-level network standard, and the user experience is poor.

It should be understood that the specific embodiments described herein are merely illustrative of the invention and do not limit the invention.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In addition, technical solutions between various embodiments may be combined with each other, but must be realized by a person skilled in the art, and when the technical solutions are contradictory or cannot be realized, such a combination should not be considered to exist, and is not within the protection scope of the present invention.
In the description of the present invention, it should be understood that the numerical references before the steps do not indicate the order of performing the steps, but merely serve to facilitate the description of the present invention and to distinguish each step, and thus, should not be construed as limiting the present invention.
The technical solution of the present application will be described in detail below with reference to specific examples.
It should be noted that the following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.
Fig. 1 is a schematic flow chart of a network format switching method provided in an embodiment of the present application, where the method may be applied to a terminal, and the terminal may be any device that can communicate with a base station, such as a mobile phone, a computer, and a tablet computer. The method may comprise the steps of:
s11: when the terminal is accessed to the first network system through the first base station, position characteristic information used for representing the current position of the terminal is obtained.
S12: sending the position characteristic information to a server, so that when the server determines that a second base station which can be accessed by the terminal currently exists according to the position characteristic information, the server sends a switching instruction for indicating the terminal to be switched to a second network system to the terminal; the second base station is a base station capable of providing a second network standard.
S13: and when receiving the switching instruction, accessing a second network system through a second base station.
The specific process of the above steps is explained in detail below.
It should be noted that the location characteristic information in step S11 may be any information that can represent the current location of the terminal.
In an alternative embodiment, the location characteristic information includes terminal location coordinates of a current location of the terminal, and the terminal location coordinates may directly represent the current location of the terminal. In this embodiment, the terminal may obtain, through the positioning module, for example, through the GPS module, a terminal position coordinate of a current position of the terminal, and then send the terminal position coordinate to the server, so that the server determines whether there is a second base station accessible to the terminal currently according to the terminal position coordinate.
In another alternative embodiment, the location characteristic information includes information that may indirectly characterize the current location of the terminal, for example, the information may include a base station identifier of the first base station, where different base stations have different corresponding base station identifiers, and the terminal is currently connected to the first base station, which indicates that the terminal is currently located within the coverage area of the base station signal of the first base station, so the base station identifier of the first base station may indirectly characterize the current location of the terminal. In this embodiment, the terminal may obtain a base station identifier of a first base station currently connected to the terminal, and send the base station identifier to the server, so that the server determines a terminal position coordinate of a current position of the terminal according to the base station identifier, and then determines whether a second base station accessible to the terminal exists currently according to the terminal position coordinate. When the terminal is in a scene with poor network quality, such as an underground garage, due to poor network signals, the terminal is difficult to be positioned through the GPS module, at the moment, the base station identification is sent to the server through acquiring the base station identification, and the server positions the terminal according to the base station identification.
The base station identifier in the embodiment of the present application may be any identifier that can represent a unique identity of a base station, and for example, may be composed of an LAC (location area code) and a CID (base station number).
It can be understood that, in the server in the embodiment of the present application, the base station location information of a plurality of base stations is stored in advance, and specifically, the correspondence between the base station identifier of each base station and the base station location information may be stored.
After receiving the base station identifier of the first base station sent by the terminal, the server may query the base station location information of the first base station according to the base station identifier, and may estimate the terminal location coordinate of the terminal according to the base station location information of the first base station. For example, the base station position information (base station position coordinates) of the first base station may be directly used as the current terminal position coordinates of the terminal, and then whether a corresponding second base station exists may be determined based on the terminal position coordinates.
For example, to achieve more accurate positioning of the terminal, when the location characteristic information includes the base station identifier of the first base station, the location characteristic information may further include: the cell identification of the cell of the first base station to which the terminal is currently accessed, and/or the signal strength information when the terminal communicates with the first base station.
The coverage range of each cell of each base station is fixed, the server may store the corresponding relationship between the base station identifier of each base station and the base station location information in advance, and at the same time, store the corresponding cell identifier for each base station, and store the information of the corresponding cell coverage range for each cell. After receiving the base station identifier of the first base station and the cell identifier of the currently accessed cell sent by the terminal, the server can inquire the cell corresponding to the base station according to the base station identifier, inquire the corresponding cell coverage area according to the cell identifier sent by the terminal, and estimate the current terminal position coordinate of the terminal according to the cell coverage area. For example, the middle point in the cell coverage may be used as the current location point of the terminal, and then it is determined whether a corresponding second base station exists based on the location point.
When the position characteristic information comprises signal strength information when the terminal is communicated with the first base station, the distance between the terminal and the first base station can be estimated according to the signal strength information, and after the server obtains the base station position information of the first base station according to the method, the current terminal position coordinate of the terminal is estimated according to the distance.
For example, before the position feature information used for representing the current position of the terminal is obtained, it may be determined that the terminal is currently in a data transmission state, and when the terminal is in the data transmission state, the requirement on the network quality is high, so that the terminal needs to be switched from the first network system to the second network system in time.
It can be understood that the handover instruction sent by the server to the terminal may include a base station identifier of the second base station, for example, LAC and CID of the second base station, after receiving the handover instruction sent by the server, the terminal may suspend the current data transmission process, send a network camping application to the corresponding second base station according to the base station identifier in the handover instruction, and resume data transmission when accessing the second network system through the second base station.
Illustratively, step S11 may further include: and when the connection state of the terminal and the second network system is disconnected and the first network system is accessed through the first base station, acquiring the position characteristic information for representing the current position of the terminal. Therefore, the terminal can be switched back to the second network system after being switched from the second network system to the first network system, so that the terminal can be connected to the second network system as far as possible.
Fig. 2 is a schematic flow chart of a network type switching method provided in an embodiment of the present application, where the method may be applied to a server, and the server in the embodiment of the present application may store base station location information of each base station in advance, where the above-mentioned base station location information of the first base station and the base station location information of the second base station may both be stored in the server in advance, and the method includes:
s21: receiving position characteristic information sent by a terminal; the position characteristic information is the characteristic information which is used for representing the current position of the terminal and is acquired when the terminal is accessed to the first network system through the first base station.
S22: when a second base station which can be accessed by the terminal is determined to exist currently according to the position characteristic information, a switching instruction for indicating the terminal to switch to a second network system is sent to the terminal, so that the terminal can access the second network system through the second base station when receiving the switching instruction; the second base station is a base station capable of providing a second network standard.
It should be noted that, in the embodiment of the present application, base station location information of each base station that can provide the second network standard may also be stored in advance in the server. Of course, in other embodiments, the base station location information of each base station that can provide the second network standard may also be obtained by the server from other devices.
When the location characteristic information includes the terminal location coordinate of the current location of the terminal, for step S22, when it is determined that the terminal is located within the coverage area of the base station signal of a certain base station according to the location information of each base station and the terminal location coordinate, the base station may be used as a second base station to which the terminal can currently access.
When the location characteristic information includes a base station identifier of the first base station, for step S22, a terminal location coordinate of a current location of the terminal may be determined according to the base station identifier of the first base station, and then, when the terminal is determined to be located within a coverage area of a base station signal of a certain base station according to the location information of each base station and the terminal location coordinate, the base station is used as a second base station accessible to the current terminal.
A process of determining whether the terminal is located within a coverage area of a base station signal of a corresponding base station according to the base station location information and the terminal location coordinates will be described below.
Assuming that the terminal position coordinate is determined to be (x 1, y 1), the base station position coordinate of the base station providing the second network type is (x 2, y 2), if any, and the base station position coordinate of the base station providing the second network type is (x 2, y 2)

Determining that the terminal is located within the coverage area of the base station signal of the base station, if
Figure BDA0003824854070000102
It is determined that the terminal is not within the coverage of the base station signal of the base station, where r is the base station signal coverage radius of the base station, and this value may be stored in the server in advance.
For example, when it is determined that the terminal is located within the coverage area of the base station signals of the plurality of base stations that can provide the second network standard, the base station closest to the terminal may be used as the second base station accessible by the current terminal.
The server can send a switching instruction to the terminal to inform that a second base station nearby the terminal can be switched, and the terminal is accessed to a second network system through the second base station after receiving the switching instruction.
It can be understood that, in practical applications, the first network standard and the second network standard may be any network standards as long as they are different. Optionally, the network level of the second network type is higher than that of the first network type, or the network priority of the second network type is higher than that of the first network type. For example, the first network System may be a GSM (Global System for Mobile Communications) network System or a WCDMA (Wideband Code Division Multiple Access) network System, and the second network System may be an LTE (Long Term Evolution) network System.
