Embodiments of the present invention will be described below with reference to the accompanying drawings.
Fig. 1 is a schematic flowchart of a method for automatically switching network modes in a private network system according to an embodiment of the present invention, which is applied to a terminal device, where the terminal device includes a modem, and the modem is in a first network mode; the method for automatically switching the network mode in the private network system can be executed by a device for automatically switching the network mode in the private network system, and the device for automatically switching the network mode in the private network system can be integrated in the terminal equipment. Referring to fig. 1, the method for automatically switching network modes in the private network system may include:
s101, the terminal device detects a network mode in the current environment.
The modem is in a first network mode, which may be a Witen network mode, a Bteunc network mode, or a 3GPP network mode.
For example, in the embodiment of the present invention, after the terminal device is booted and restarted, a network mode in the current environment may be detected, where the network mode in the current environment may be a Witen network mode, a Bteunc network mode, or a 3GPP network mode.
S102, if the network mode in the current environment is different from the first network mode, the terminal equipment switches the first network mode of the modem to the network mode in the current environment.
After the terminal device detects the network mode in the current environment through the above S101, by determining that the network mode in the current environment is different from the first network mode, the first network mode of the modem is automatically switched to the network mode in the current environment, so that the automatic switching of the network mode of the modem is realized without returning to a manufacturer to upgrade a version again, and the switching efficiency of the network mode is further improved.
According to the method for automatically switching the network mode in the private network system, provided by the embodiment of the invention, the network mode of the terminal equipment in the current environment is detected, and if the network mode in the current environment is different from the first network mode, the terminal equipment switches the first network mode of the modem to the network mode in the current environment, so that the automatic switching of the network mode of the modem is realized, a manufacturer does not need to return to upgrade versions again, and the switching efficiency of the network mode is further improved.
Based on the embodiment shown in fig. 1, further, please refer to fig. 2, where fig. 2 is a schematic flow chart of another method for automatically switching a network mode in a private network system according to an embodiment of the present invention, and the method for automatically switching a network mode in a private network system may further include:
s201, the terminal equipment sends a query instruction to the current network equipment.
The query instruction is used for querying the identifier of the network mode in the current environment. Optionally, in the embodiment of the present invention, the query instruction may be an AP query instruction, and of course, may also be another query instruction as long as the query instruction can be used to query the identifier of the network mode in the current environment.
After the terminal device is booted and restarted, the network mode in the current environment may be detected by sending a query instruction to the current network device, where it should be noted that the modem of the terminal device is in the first network mode, and the first network mode may be a Witen network mode, a Bteunc network mode, or a 3GPP network mode.
S202, the terminal equipment receives a response instruction sent by the network equipment.
Wherein the response instruction comprises an identification of the network mode in the current environment.
After receiving the query instruction sent by the terminal device, the network device queries the identifier of the network mode in the current environment, and after determining the identifier of the network mode in the current environment, returns a response instruction including the identifier of the network mode in the current environment to the terminal device, so that the terminal device receives the response instruction, and determines the identifier of the network mode in the current environment according to the response instruction.
S203, the terminal equipment determines the network mode under the current environment according to the identifier of the network mode under the current environment.
And S204, if the network mode in the current environment is different from the first network mode, the terminal equipment determines the configuration information corresponding to the network mode in the current environment.
After determining the network mode in the current environment according to the identifier of the network mode in the current environment through S203, if the network mode in the current environment is different from the first network mode, the first network mode of the modem needs to be upgraded to the network mode in the current environment, at this time, configuration information corresponding to the network mode in the current environment needs to be further acquired, and the modem needs to be upgraded according to the configuration information corresponding to the network mode in the current environment, so as to upgrade the first network mode of the modem to the network mode in the current environment.
Optionally, in this embodiment of the present invention, determining, by the terminal device, the configuration information corresponding to the network mode in the current environment may include:
the terminal equipment prestores configuration information corresponding to at least two preset network modes; the network mode under the current environment belongs to at least two preset network modes; and searching the configuration information corresponding to the network mode in the current environment from the configuration information corresponding to the at least two preset network modes according to the identifier of the network mode in the current environment so as to determine the configuration information corresponding to the network mode in the current environment.
For example, in the embodiment of the present invention, the at least two preset network modes may be three, and the three preset network modes may be a Witen network mode, a Bteunc network mode, and a 3GPP network mode.
Therefore, in the embodiment of the present invention, since the terminal device pre-stores the configuration information corresponding to the Witen network mode, the Bteunc network mode, and the 3GPP network mode, and the network mode in the current environment is one of the three network modes, when the terminal device obtains the configuration information corresponding to the network mode in the current environment, the terminal device can directly query the configuration information corresponding to the pre-stored pre-set network mode according to the identifier of the network mode in the current environment, so as to obtain the configuration information corresponding to the network mode in the current environment.
S205, the terminal device upgrades the network mode of the modem according to the configuration information corresponding to the network mode in the current environment, so as to switch the first network mode to the network mode in the current environment.
After the terminal equipment acquires the configuration information corresponding to the network mode in the current environment, the network mode of the modem can be upgraded according to the configuration information corresponding to the network mode in the current environment, so that the first network mode is switched to the network mode in the current environment, the automatic switching of the network mode of the modem is realized, a manufacturer does not need to return to upgrade the version again, and the switching efficiency of the network mode is improved.
In order to more clearly illustrate the method for automatically switching network modes in a private network system provided by the embodiment of the present invention, taking the case that a modem of a terminal device is in a Bteunc network mode, and a network mode of a current environment of the terminal device is a 3GPP network mode, after the terminal device is powered on and restarted, by sending a query instruction to the network device, and obtaining an identifier of the 3GPP network mode of the current environment according to a response instruction, comparing the identifier of the 3GPP network mode with an identifier of the Bteunc network mode of the modem, and if the identifier of the 3GPP network mode is different from the identifier of the Bteunc network mode of the modem, switching the Bteunc network mode of the modem to the 3GPP network mode; during switching, the configuration information corresponding to the 3GPP network mode needs to be acquired first, and since the terminal device stores the configuration information corresponding to the 3GPP network mode in advance, the terminal device can directly query and acquire the configuration information corresponding to the 3GPP network mode according to the identifier of the 3GPP network mode, and then can upgrade the modem according to the configuration information corresponding to the 3GPP network mode to switch the Bteunc network mode of the modem to the 3GPP network mode, thereby implementing automatic switching of the network mode of the modem without returning to a manufacturer to upgrade a version, and further improving the switching efficiency of the network mode.
