s1501: and determining a corresponding event processing function according to the event identifier through the wireless interface layer interface, and transmitting the request information and the event identifier to a modem interface by using the event processing function.

The wireless interface layer interface qcril is one of modules provided by a high-pass and used for communication between the AP side and the modem, a static form is stored in the qcril, and event identifications of all upper layer issued requests and corresponding event processing functions are stored in the qcril, wherein the event identifications correspond to the event identifications of system frequency band operation configured by the wireless interface layer processing functions one by one, namely the same event identifications are inquired in the qcril static form according to the event identifications of the system frequency band operation configured by the wireless interface layer processing functions, and the processing functions under the event identifications are called.

In a qcril static form in the prior art, event identifications and corresponding processing functions for locking and unlocking network systems and frequency bands are not provided, so that in the embodiment provided by the application, the event identifications and the processing functions thereof are added.

When the upper layer issues request information of locking network system and frequency band or unlocking network system and frequency band, qcril can clearly process the request information.

S1502: and receiving the request information and the event identification sent by the wireless interface layer interface by using the modem interface, and transmitting the request information and the event identification to the modem.

The radio interface layer interface initiates a modem interface request message (QMI request msg) to the modem side through a modem interface client (QMI client).

In the above S303, the modem calls a corresponding system frequency band configuration function according to the event identifier, and performs corresponding operation on the selected network system and the selected frequency band according to the operation instruction type in the network system of the operator information in the request information, which may specifically be implemented as follows:

the modem determines to call a first system frequency band configuration function for locking a network system and a frequency band according to the first event identifier, and performs locking operation on the selected network system and the selected frequency band according to the operation instruction type under the network system of the operator information in the request information;

and the modem calls the first standard frequency band configuration function to set the value in the corresponding nv item, and searches the network according to the modified nv item value. And when the instruction operation type is determined to be a first operation instruction and the modulator-demodulator is determined to be successful in searching the selected network system and frequency band, displaying that the corresponding network system and the frequency band are locked successfully on the user interface, otherwise, displaying that the corresponding network system and the frequency band are locked unsuccessfully and staying on the list display interface of the selectable network system and the frequency band.

For example, the network type and frequency band to be locked in the request information are LTE B7(2600), the operator information is china unicom, at this time, the modem determines to set the network type in nv #10 as LTE, sets the value in nv #65633 as 2600, then the modem performs corresponding network search to the network side device (base station) of china unicom, if the search is successful, it is displayed on the user interface that the locking of the corresponding network type and frequency band is successful, as shown in fig. 16, the display is successful on the network type and frequency band list display interface. The successful position is not limited to the bottom of the screen, and can be positioned at the top of the screen or positioned at the upper layer of a network system and a frequency band list in the figure, and disappears after staying for 1-2 seconds. The identifier indicating success may be a chinese character, an english character, or a boolean value, and is not particularly limited herein.

If the network search fails, a failure in locking the corresponding network system and frequency band is displayed on the user interface, and as shown in fig. 17, a failure is displayed on the network system and frequency band list display interface. The position of the failure is not limited to the bottom of the screen, and can be positioned at the top of the screen or positioned at the upper layer of the list in the figure, and the failure disappears after staying for 1-2 seconds. The identifier indicating the failure may be a chinese character, an english character, or a boolean value, and is not particularly limited herein.

And when the modem receives the event identifier indicating the network system and the frequency band to be unlocked and executes a second frequency band configuration function for unlocking the network system and the frequency band, the numerical value in the nv item is not set but network search is directly carried out.

For example, as shown in fig. 18, click to cancel the previously selected LTE B7(2600) on the left network system and the frequency band list display interface, and then click to "circle" at the bottom of the screen to start the unlocking operation. And transmitting the second operation instruction, the network system and the frequency band to be unlocked to a modem side, searching all network systems and frequency bands of network side equipment under Chinese communication by using the modem, determining the network system and the frequency band with the strongest signals in the searched network system and frequency band list as target network systems and frequency bands, and displaying the selected LTE B8(900) on a display interface of a right network system and frequency band list if the target network system and the frequency band are LTE B8 (900). At this time, the unlocking is successful, and the display result cannot be operated on the display interface of the right network system and the frequency band list. In the unlocking process, the target network system and the frequency band which are possibly obtained finally are the same as those locked before, and the situation shows that the network system and the frequency band have the strongest signals.
