Detailed Description
In order to improve the cruising ability of the mobile terminal, the invention provides a power supply control method and device of a mobile communication card in the mobile terminal and the mobile terminal. It should be understood that the specific embodiments described herein are merely illustrative of the invention and do not limit the invention.
As shown in fig. 1, a method for controlling power supply of a mobile communication card in a mobile terminal in an embodiment of the present invention includes the following steps:
s401, when a 3GPP radio frequency of a mobile terminal registered to a non-3GPP network is closed, judging whether the mobile terminal initiates an access operation to the mobile communication card within a preset time;
s402, when the mobile communication card is not initiated, the power of the mobile communication card is cut off.
The mobile communication card includes a USIM (Universal Subscriber Identity Module), a SIM (Subscriber Identity Module), and the like. For clarity and brevity, the mobile communication card may be referred to herein simply as a card or card module.
The access operation comprises business operation and file operation in the mobile communication card; the service operation comprises service operations such as registration, call making, authentication and the like; the file operation comprises updating files in the card, such as short messages, name card folders and the like in the card.
The method in the embodiment of the invention controls the power supply of the mobile communication card under the condition of ensuring the normal work of the mobile communication card, thereby obviously improving the cruising ability of the mobile terminal.
Briefly describe the implementation principle of the method in the embodiment of the present invention.
For a mobile terminal (terminal for short), a USIM card is an important component thereof. The terminal needs to periodically check the state of the USIM card under the mobile cellular network so as to maintain authentication, access and other operations of the mobile network.
With the development of communication Networks, more and more Wireless Access schemes are used, such as 3GPP network LTE (Long Term Evolution), WCDMA (Wideband Code Division Multiple Access), GSM (Global System for Mobile communication), and non-3GPP network, such as WLAN (Wireless Local Area network), HRPD (High Rate Packet Data), WIMAX (Worldwide Interoperability for Microwave Access).
Can be selectively accessed to a 3GPP or NON-3GPP (i.e., NON-3 GPP) network, and the card needs to be continuously powered to identify the legality, mobility and the like of the network. After accessing to the NON-3GPP network, the radio frequency of the wireless cellular radio frequency can be turned off, and the card only needs to be operated when the card is accessed for the first time, services are performed (for example, registration and call making) and card files are operated (for example, short messages and name card folders in the card are updated), and the card is in a NON-working state and a standby state most of the time. For the non-working state of the card, the continuous power supply of the card is a waste of the power supply, and the method in the embodiment of the invention is realized based on the waste.
According to the protocol, the card classes are CLASS a, CLASS B and CLASS C, corresponding to 5V, 3V and 1.8V supply voltages, respectively, as follows:
card rating Supply voltage
CLASS A 5V
CLASS B 3V
CLASS C 1.8V
When the card is in a working state, the session consumption current intervals of CLASS A, CLASS B and CLASS C are respectively 10-60 mA, 10-50 mA and 10-30 mA.
If the card is in an off state, the card needs to be powered continuously, according to the current protocol, the maximum current of RST (reset) and CLK (Clock) of the card is 150uA, the maximum current of CLK (Clock) is 100uA, and under a normal state, the consumed current is about 40-60%, that is, the current of RST and CLK is about (150+100) × 40-60%, and about 100 uA-150 uA. This is the current when the card has no session at all, and most of the current cannot reach this level, and the current of the card will be higher when the card is standby.
In the standby state, the consumed current is about 3-6 mA, and if the WeChat, WLAN and the like are started, the standby current is about 15-25 mA. With the development of the NON-3GPP network, when the NON-3GPP network is completed, the mobile cellular radio unit is turned off, the current consumption is further reduced, and the proportion of the current consumed by the card in standby is increased.
In conclusion, the method in the embodiment of the invention can effectively reduce the current consumed by the card, thereby obviously improving the cruising ability of the mobile terminal.
Of course, in the method of the embodiment of the present invention, after the card is registered in the NON-3GPP network, after the operations such as registration authentication and the like are completed, if the card is in the standby state basically, due to the characteristics of the card, only the device can initiate an active command to the card, and the card can only respond to the command, so that the card can be actively called again when the card is needed.
On the basis of the above-mentioned embodiment, modified embodiments of the above-mentioned embodiment are further proposed, and it is to be noted herein that, in order to make the description brief, only the differences from the above-mentioned embodiment are described in each modified embodiment.
In an embodiment of the present invention, before the step of turning off the 3GPP radio frequency, the method may further include:
copying a readable file designated in the mobile communication card;
and storing the copied appointed readable file copy to the moved preset storage area.
The specified readable file may include card files stored in the card, such as a short message, a name card holder, an IMSI (International Mobile Subscriber Identity), and an ISIM (IMSI). It is assumed that the storage area may be one of the temporary storage areas set in.
According to the embodiment of the invention, the specified readable file copy is stored in the preset storage area, so that the file on the card can be checked through the preset storage area when the card is powered off (power failure), the current consumed by the card is further reduced, and the moving cruising ability is further improved.
That is, after the step of powering off the mobile communication card, the method further includes:
and when the mobile communication card initiates an inquiry instruction for the specified readable file in the mobile communication card, reading the specified readable file copy from the preset storage area and displaying the read file copy.
Further, after the step of reading and displaying the specified readable file copy from the preset storage area, the method further includes:
when the specified readable file copy is modified, supplying power to the mobile communication card;
and switching to the specified readable file from the specified readable file copy, and initiating a file updating operation on the mobile communication card through the movement.
In another embodiment of the present invention, after the step of powering off the mobile communication card, the method further includes:
when the mobile communication card initiates an access operation on the mobile communication card, supplying power to the mobile communication card; the access operation comprises a registration operation, an authentication operation and a file update operation. Such as registration service operation, authentication operation when dialing a call, and updating operation of files such as name card folders and short messages.
When the file in the card is updated, the mobile communication card can actively initiate a file updating instruction to the mobile communication card, so that the problem of updating the file in the card is solved.
Wherein the file update operation comprises:
initiating a file update instruction to the mobile communication card through the movement to cause the mobile communication card to update the specified readable file;
and updating the specified readable file copy when an updating success result responded by the mobile communication card is received.
In order to describe the embodiment of the present invention more clearly, the method in the embodiment of the present invention is further described in three specific application examples.
Application example one
Judging whether the mobile terminal initiates an access operation to the mobile communication card within a preset time; when the mobile communication card is not initiated, the mobile communication card is powered off, so that the terminal enters a card module power saving mode, as shown in fig. 2, the flow is as follows:
s101, the terminal is started after the card is inserted.
S102, after the terminal is powered on, the card is powered on to perform card processing procedures such as ATR (answer to reset, response to reset command), PPSS (Protocol and parameters selection negotiation between the card and the terminal), and reading a file readable in the card.
S103, copying the readable file to a terminal temporary storage area, for example, storing copies of IMSI, name card folder, short message and the like to the terminal temporary storage area (preset storage area).
And S104, the terminal searches for the network and registers the network.
S105, the terminal judges whether the registered network type is a 3GPP network, if so, S106 is executed, and if not, S107 is executed.
And S106, the 3GPP network continuously supplies power to the card and processes the card according to the 3GPP process without influencing the terminal.
S107, the terminal registers to the NON-3GPP network.
S108, if the terminal is registered to the NON-3GPP network, judging whether a 3GPP wireless radio frequency module of the terminal is closed, if the 3GPP wireless radio frequency module is not closed, executing S109, and if the 3GPP wireless radio frequency module is closed, executing S110.
And S109, keeping the card in a continuous power supply state.
S110, if the 3GPP wireless radio frequency module of the terminal is closed, whether the operation command of the terminal to the card file is completed within the preset time is judged, if the operation command is completed, S111 is executed, and if the operation command is not completed, S109 is executed. For example, if it is completed and there is no card file operation command within T time (preset time) (T time may have a terminal setting, e.g., 5S, or 10S), S111 is performed.
And S111, performing power-off processing on the card. And closing the card module, and enabling the terminal to enter a power-saving state.
Application example two
The process of the terminal dialing the telephone and needing the card to authenticate is shown in fig. 3 and comprises the following steps:
s201, the terminal registers to the NON-3GPP network.
S202, the terminal completes power-off processing of the card;
at which time the user makes a call.
S203, the terminal supplies power to the card, ATR (answer to reset command), PPSS (Protocol and parameters selection negotiation between the card and the terminal), and the card enters into the working state.
And S204, after the card enters the working state, the terminal sends the authentication command to the card.
S205, the card processes the received authentication command and responds the authentication result through the authentication module.
S206, if the authentication command passes, the terminal establishes a call.
And S207, after the terminal conversation is finished, executing S208.
And S208, entering an application example flow S107 to judge the current terminal state again.
Application example three
The file update process is shown in fig. 4, and includes:
s301, the terminal registers to the NON-3GPP network.
S302, the terminal enters a card power saving state.
And at the moment, the user updates the file operation of the temporary storage area of the terminal card through the UI menu.
And S303, displaying and modifying the data in the temporary storage area (the preset storage area of the terminal) of the terminal card.
S304, when the user issues the update command, the card is powered on, ATR (answer to reset) is carried out, PPSS (Protocol and parameters selection negotiation between the card and the terminal) is carried out, and the card enters into the working state.
S305, after the card file enters the working state, the temporary storage area of the terminal card is switched back to the storage area of the card file, and the terminal sends a command to the card to request for updating the file in the card.
S306, the terminal responds to the card file updating result, if the updating is successful, the file data in the temporary storage area of the terminal card is synchronously updated, and if the updating is failed, the response result is transmitted to the terminal.
S307, entering an application example flow S107 to judge the current terminal state again.
When the terminal inserts the card and starts up to supply power to the card, the card performs parameter negotiation and reads card files, and simultaneously copies and stores the readable files in the card, such as short messages, name card folders, IMSIs, ISIMs and other card files stored in the card, into a temporary storage area of the terminal. The terminal can also view the files on the card through the temporary storage area when the card is powered off. For unreadable and non-operational parts such as ki values and authentication processes, when the terminal needs the card for processing, the card is powered up again, and the relevant commands are transmitted to the card for processing.
As shown in fig. 5, in a protocol framework according to an embodiment of the present invention, a terminal supports a card module and can store a file readable in the card in a temporary storage area, and the terminal can operate a card module unit through an Application Programming Interface (API) Application Interface and can also operate a file in the temporary storage area. While the card module unit and the temporary storage can communicate.
When the terminal registers to a cell and the Radio frequency is turned on, the terminal can directly operate the card file unit through a physical layer, and the MAC (Media Access Control) layer, the RLC (Radio Link Control) layer, the RRC (Radio Resource Control) layer, the NAS (Non-Access stratum) layer, and the like do not need to be changed and directly maintain communication with the bottom layer. When the terminal registers in the WLAN cell, the radio frequency is closed, and the card module is closed, the bottom layer of the terminal can communicate with the temporary storage area to operate the file in the temporary storage area, and the temporary storage area can call and activate the card module unit. And after the user operates the temporary storage area, the temporary storage area of the terminal recalls and activates the card module unit, and the files and data in the card module unit are updated.
