S1202: when a plurality of SIM cards are determined to be identified, a SIM card selection interface is displayed on a user interface in response to a network type frequency band operation instruction, a selectable network type and frequency band list corresponding to the SIM cards is displayed on the display interface according to the SIM cards selected by the user, and operation information of the user for the network type and frequency band selection is transmitted to a telephone management unit through a framework program interface.

In a terminal supporting multiple SIM cards, different SIM card slots correspond to different nv items in a modem, so that for the terminal, after responding to a network type frequency band operation instruction, it is necessary to first select a SIM card to be operated, and then select a network type and a frequency band corresponding to the SIM card.

Specifically, as shown in fig. 13, a SIM card list is displayed on a display interface, a user selects SIM2 according to the requirement, then clicks a right triangle below the screen, and switches to a network system and a frequency band list corresponding to SIM2, when the SIM2 is mistakenly selected to enter the network system and the frequency band list of SIM2, the user can click a right triangle at the bottom of the network system and frequency band list display interface, and then can return to the upper menu (SIM card list); or as shown in fig. 14, directly clicking the column in which SIM2 is located, so that the interface is switched to the network system and the frequency band list corresponding to SIM2, and the right triangle in fig. 14 indicates that the column has the next menu. The specific operation mode of switching from the SIM card list display interface to the network system and frequency band list display interface may also be that the SIM card is automatically switched to the corresponding network system and frequency band list after being selected, and the embodiment of the present application is not specifically limited.

The transmission channel in S303 includes a radio interface layer interface and a modem interface, and is transmitted to the modem through the transmission channel between the radio interface layer and the modem, specifically, as shown in fig. 15, through the following embodiments:

S1501: and determining a corresponding event processing function according to the event identification through the wireless interface layer interface, and transmitting the request information and the event identification to a modem interface by utilizing the event processing function.

The wireless interface layer interface qcril is one of the modules of the AP side and the modem side for high-pass communication, a static form is stored in qcril, and event identifications of all upper layer issuing requests and corresponding event processing functions are stored therein, wherein the event identifications are in one-to-one correspondence with event identifications of standard frequency band operation configured by the wireless interface layer processing functions, i.e. the event identifications of standard frequency band operation configured according to the wireless interface layer processing functions query the same event identifications in qcril static form, and call the processing functions under the event identifications.

In the qcril static form in the prior art, the event identification of the network system and the frequency band and the corresponding processing function thereof are not locked, and the event identification of the network system and the frequency band and the corresponding processing function thereof are not unlocked, so that the event identification and the processing function thereof are added in the embodiment provided by the application.

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

S1502: and receiving the request information and the event identification sent by the wireless interface layer interface by utilizing 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 via a modem interface client (QMI CLIENT).

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

The modem determines to call a first system frequency band configuration function for locking network system and frequency band according to the first event identification, and performs locking operation on the selected network system and 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 when the modulator-demodulator is determined to search the selected network system and frequency band successfully, displaying that the locking of the corresponding network system and frequency band is successful on a user interface, otherwise, displaying that the locking of the corresponding network system and frequency band is failed on the user interface and staying on the list display interface of the selectable network system and frequency band.

For example, the network system and the 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 that the network system in nv#10 is set as LTE, the value in nv#65633 is set as 2600, and then the modem performs a corresponding network search to the network side device (base station) of china Unicom, if the search is successful, the user interface displays that the locking of the corresponding network system and the frequency band is successful, as shown in fig. 16, and the display interface displays that the locking is successful on the network system and the frequency band list display interface. The position of success is not limited to the bottom of the screen, and can be positioned at the top of the screen or at the upper layer of a network system and a frequency band list in the figure, and the success disappears after staying for 1-2 seconds. Which represents a successful identifier and may be a chinese character or an english character or a boolean value, not specifically limited herein.

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

When the modem receives an event identifier indicating unlocking network system and frequency band and executes a second frequency band configuration function unlocking network system and frequency band, the numerical value in the nv item is not set, but network searching is directly carried out.

For example, as shown in fig. 18, clicking cancels LTE B7 previously selected on the left network system and frequency band list display interface (2600), and then clicking "circle" at the bottom of the screen starts the unlocking operation. And transmitting the second operation instruction and 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 China Unicom by using the modem, determining the network system and the frequency band with the strongest signal in the searched network system and frequency band list as a target network system and frequency band, and if the target network system and frequency band is LTE B8 (900), displaying the selected LTE B8 (900) on a right network system and frequency band list display interface. At this time, the unlocking is successful, and the display result cannot be operated on the right network system and the frequency band list display interface. In the unlocking process, the target network system and frequency band possibly obtained finally are the same as those locked before, and the situation shows that the network system and frequency band signals are strongest.
