[0050] does not limit the mobile terminal. The mobile terminal may include more or fewer components than those shown in the figure, or combine certain components, or have different component arrangements. Figure 1 The following specifically introduces each component of the mobile terminal:

[0051] The RF unit 101 can be used to receive and send signals during information reception or call processes. Specifically, after receiving the downlink information of the base station, it is given to the processor 110 for processing; in addition, the uplink data is sent to the base station. Usually, the RF unit 101 includes, but is not limited to, an antenna, at least one amplifier, a transceiver, a coupler, a low-noise amplifier, a duplexer, etc. In addition, the RF unit 101 can also communicate with the network and other devices through wireless communication. The above wireless communication can use any communication standard or protocol, including but not limited to GSM (Global System of Mobile communication), GPRS (General Packet Radio Service), CDMA2000 (CodeDivision Multiple Access 2000), WCDMA (Wideband Code DivisionMultiple Access), TD-SCDMA (Time Division-Synchronous CodeDivision Multiple Access), FDD-LTE (Frequency DivisionDuplexing-Long Term Evolution), and TDD-LTE (Time DivisionDuplexing-Long Term Evolution), etc.

[0052] WiFi belongs to short - range wireless transmission technology. Through the WiFi module 102, the mobile terminal can help users send and receive emails, browse the web, and access streaming media, etc. It provides users with wireless broadband Internet access. Although Figure 1 the WiFi module 102 is shown, it can be understood that it does not belong to the essential components of the mobile terminal and can be completely omitted within the scope of not changing the essence of the invention according to needs.

[0053] The audio output unit 103 can convert the audio data received by the radio frequency unit 101 or the WiFi module 102 or stored in the memory 109 into an audio signal and output it as sound when the mobile terminal 100 is in modes such as a call signal reception mode, a call mode, a recording mode, a voice recognition mode, a broadcast reception mode, etc. Moreover, the audio output unit 103 can also provide an audio output related to the specific functions executed by the mobile terminal 100 (for example, a call signal reception sound, a message reception sound, etc.). The audio output unit 103 can include a speaker, a buzzer, etc.

[0054] The A / V input unit 104 is used to receive audio or video signals. The A / V input unit 104 can include a Graphics Processing Unit (GPU) 1041 and a microphone 1042. The graphics processor 1041 processes the image data of still pictures or videos obtained by an image capture device (such as a camera) in a video capture mode or an image capture mode. The processed image frames can be displayed on the display unit 106. The processed image frames can be stored in the memory 109 (or other storage media) or transmitted via the radio frequency unit 101 or the WiFi module 102. The microphone 1042 can receive sounds (audio data) via the microphone 1042 in operating modes such as a phone call mode, a recording mode, a voice recognition mode, etc., and can process such sounds into audio data. The processed audio (voice) data can be output in a format that can be transmitted to a mobile communication base station via the radio frequency unit 101 in the case of a phone call mode. The microphone 1042 can implement various types of noise cancellation (or suppression) algorithms to eliminate (or suppress) the noise or interference generated during the reception and transmission of audio signals.

[0055] The mobile terminal 100 further includes at least one sensor 105, such as a light sensor, a motion sensor, and other sensors. Specifically, the light sensor includes an ambient light sensor and a proximity sensor. Among them, the ambient light sensor can adjust the brightness of the display panel 1061 according to the brightness of the ambient light, and the proximity sensor can turn off the display panel 1061 and / or the backlight when the mobile terminal 100 is moved to the ear. As a kind of motion sensor, the accelerometer sensor can detect the magnitude of acceleration in all directions (generally three axes), and can detect the magnitude and direction of gravity when stationary, and can be used in applications for identifying the posture of the mobile phone (such as horizontal and vertical screen switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer, tapping), etc.; as for other sensors that the mobile phone can also be configured with, such as fingerprint sensors, pressure sensors, iris sensors, molecular sensors, gyroscopes, barometers, hygrometers, thermometers, infrared sensors, etc., they will not be elaborated here.

[0056] The display unit 106 is used to display information input by the user or information provided to the user. The display unit 106 may include a display panel 1061, and the display panel 1061 may be configured in the form of a liquid crystal display (LCD), an organic light-emitting diode (OLED), etc.

[0057] The user input unit 107 can be used to receive input digital or character information, and generate key signal inputs related to the user settings and function controls of the mobile terminal. Specifically, the user input unit 107 may include a touch panel 1071 and other input devices 1072. The touch panel 1071, also known as a touch screen, can collect touch operations of the user on or near it (such as operations of the user using a finger, a stylus, or any suitable object or accessory on or near the touch panel 1071), and drive the corresponding connection device according to a preset program. The touch panel 1071 may include two parts: a touch detection device and a touch controller. Among them, the touch detection device detects the touch position of the user and detects the signal brought by the touch operation, and transmits the signal to the touch controller; the touch controller receives the touch information from the touch detection device, converts it into touch point coordinates, and then sends it to the processor 110, and can receive and execute the commands sent by the processor 110. In addition, the touch panel 1071 can be implemented in a variety of types, such as resistive, capacitive, infrared, and surface acoustic wave. In addition to the touch panel 1071, the user input unit 107 may further include other input devices 1072. Specifically, the other input devices 1072 may include, but are not limited to, one or more of a physical keyboard, function keys (such as volume control keys, power on / off keys, etc.), a trackball, a mouse, a joystick, etc., and specific details are not limited here.

[0058] Further, the touch panel 1071 may cover the display panel 1061. After the touch panel 1071 detects a touch operation on or near it, it transmits the operation to the processor 110 to determine the type of touch event. Subsequently, the processor 110 provides a corresponding visual output on the display panel 1061 according to the type of touch event. Although in Figure 1 , the touch panel 1071 and the display panel 1061 are implemented as two independent components to realize the input and output functions of the mobile terminal, in some embodiments, the touch panel 1071 and the display panel 1061 may be integrated to realize the input and output functions of the mobile terminal, and the specific implementation here is not limited.

[0059] The interface unit 108 serves as an interface through which at least one external device can be connected to the mobile terminal 100. For example, the external device may include a wired or wireless headset port, an external power supply (or battery charger) port, a wired or wireless data port, a memory card port, a port for connecting a device with an identification module, an audio input / output (I / O) port, a video I / O port, a headset port, and so on. The interface unit 108 can be used to receive inputs from external devices (such as data information, power, etc.) and transmit the received inputs to one or more components within the mobile terminal 100 or can be used to transmit data between the mobile terminal 100 and external devices.

[0060] The memory 109 can be used to store software programs and various data. The memory 109 mainly includes a program storage area and a data storage area. Among them, the program storage area can store an operating system, application programs required for at least one function (such as a sound playback function, an image playback function, etc.); the data storage area can store data created according to the use of the mobile phone (such as audio data, a phone book, etc.). In addition, the memory 109 may include a high-speed random access memory and may also include a non-volatile memory, such as at least one magnetic disk storage device, a flash memory device, or other non-volatile solid-state storage devices.

[0061] The processor 110 is the control center of the mobile terminal. It uses various interfaces and lines to connect all parts of the entire mobile terminal. By running or executing software programs and / or modules stored in the memory 109, and by calling data stored in the memory 109, it executes various functions of the mobile terminal and processes data, thereby monitoring the mobile terminal as a whole. The processor 110 may include one or more processing units; preferably, the processor 110 may integrate an application processor and a modem processor. Among them, the application processor mainly processes the operating system, user interface, and application programs, etc., and the modem processor mainly processes wireless communication. It can be understood that the above-mentioned modem processor may not be integrated into the processor 110.

[0062] The mobile terminal 100 may further include a power source 111 (such as a battery) for powering each component. Preferably, the power source 111 may be logically connected to the processor 110 through a power management system, so as to implement functions such as management of charging, discharging, and power consumption management through the power management system.

[0063] Although Figure 1 not shown, the mobile terminal 100 may further include a Bluetooth module, etc., which will not be elaborated here.

[0064] For the convenience of understanding the embodiments of the present invention, the communication network system on which the mobile terminal of the present invention is based will be described below.

[0065] Please refer to Figure 2 , Figure 2 which is an architecture diagram of a communication network system provided by an embodiment of the present invention. The communication network system is an LTE system of a general mobile communication technology. The LTE system includes a UE (User Equipment) 201, an E-UTRAN (Evolved UMTS Terrestrial Radio Access Network) 202, an EPC (Evolved Packet Core) 203, and an IP service 204 of an operator that are sequentially communicatively connected.

[0066] Specifically, the UE 201 may be the above terminal 100, which will not be elaborated here.

[0067] The E-UTRAN 202 includes an eNodeB 2021 and other eNodeBs 2022, etc. Among them, the eNodeB 2021 may be connected to other eNodeBs 2022 through a backhaul (such as an X2 interface), the eNodeB 2021 is connected to the EPC 203, and the eNodeB 2021 may provide access for the UE 201 to the EPC 203.

[0068] The EPC 203 may include an MME (Mobility Management Entity) 2031, an HSS (Home Subscriber Server) 2032, other MMEs 2033, an SGW (Serving Gate Way) 2034, a PGW (PDN Gate Way) 2035, a PCRF (Policy and Charging Rules Function) 2036, etc. Among them, the MME 2031 is a control node that processes the signaling between the UE 201 and the EPC 203 and provides bearer and connection management. The HSS 2032 is used to provide some registers to manage functions such as a home location register (not shown in the figure) and stores some user-specific information such as service characteristics and data rates. All user data can be sent through the SGW 2034. The PGW 2035 can provide IP address allocation for the UE 201 and other functions. The PCRF 2036 is a policy and charging control policy decision point for service data flows and IP bearer resources, and it selects and provides available policy and charging control decisions for a policy and charging enforcement function unit (not shown in the figure).

[0069] The IP service 204 may include the Internet, an intranet, an IMS (IP Multimedia Subsystem), or other IP services, etc.

[0070] Although the above has been described by taking the LTE system as an example, those skilled in the art should be aware that the present invention is not only applicable to the LTE system, but also applicable to other wireless communication systems, such as GSM, CDMA2000, WCDMA, TD-SCDMA, and future new network systems, etc., which are not limited herein.

[0071] Based on the above mobile terminal hardware structure and communication network system, various embodiments of the method of the present invention are proposed.

[0072] Embodiment 1

[0073] Figure 3 It is a flowchart of the first embodiment of the price tag control method of the present invention. A price tag control method, the method includes:

[0074] S1. Scan the identification code of the price tag and obtain the network address of the price tag through the identification code.

[0075] S2. Send the network address to the server and obtain a first verification value sent by the server, where the first verification value is calculated from the network address and a preset parameter.

[0076] S3. Send the first check value to the price tag so that the price tag compares the first check value with the second check value stored therein.

[0077] S4. If the first check value is the same as the second check value, control the price tag to enter the working state; if the first check value is different from the second check value, control the price tag to enter the sleep state.

[0078] In this embodiment, first, based on the address and check redundancy code stored in the electronic price tag register, a register is reserved in the control chip of the electronic price tag to store the CRC (Cyclic Redundancy Check) code of the price tag address, and the CRC check value of the address is calculated by using the CRC-QITT polynomial generated by the CRC code; then, the CRC check value and the price tag IP address are implanted into the register of the price tag control chip together; the same program for calculating the CRC code by using the CRC-QITT polynomial is also used in the binding server; when binding the price tag with a handheld device, first scan the QR code to read the price tag IP address, and then send it to the binding server; the server uses the program for calculating the CRC code by using the CRC-QITT polynomial to calculate the corresponding CRC check value according to the address value and sends it to the handheld device; after receiving the check value from the server, the handheld device sends an activation instruction to the electronic price tag; the instruction received by the price tag contains the CRC check value, which is compared with the CRC value stored in its own register; if they are consistent, an interrupt instruction is started to control the price tag to enter the network search state after restart; if they are inconsistent, the electronic price tag is controlled to enter the ultra-long sleep state, so that it cannot receive the broadcast of the base station.

[0079] Optionally, in this embodiment, the binding server and the handheld device communicate with each other. The server sends the calculated CRC check value to the handheld device according to the IP address and the CRC code, and then the handheld device issues an interrupt instruction to the price tag.

[0080] Optionally, in this embodiment, the price tag controller and the CRC logic processing module are bound. The price tag controller receives the interrupt instruction and compares it with the CRC check value in its own register. If they are consistent, the price tag is restarted and enters the fast network search state; otherwise, it enters the ultra-long sleep state.

[0081] Optionally, in this embodiment, the ID of the price tag and the corresponding CRC program are burned in the production line. Thereafter, the price tag enters the ultra-long sleep state; when the mall wants to bind the price tag to a commodity, the handheld device reads the price tag IP and sends it to the binding server, and the server calculates the check code value of the price tag through the CRC program and then sends the CRC value to the handheld device.

[0082] Optionally, in this embodiment, when the handheld device receives the CRC value, it sends an interrupt instruction to the price tag. The price tag receives the interrupt instruction and compares it with the CRC value in its own register. If they are the same, the price tag is restarted and enters the standby state; otherwise, it enters the ultra-long sleep state.

[0083] Optionally, in this embodiment, through the price tag single-chip microcomputer, for example, a 16-bit MCU microcontroller system pre-calculates the CRC code of the electronic price tag address. Then, during the calculation of the CRC of the address, the generating polynomial of the CRC code is CRC-QITT, and its generated polynomial is: G(x) = X16 + X12 + X5 + 1. The corresponding code of G(x) is: 1 0001 0000 0010 0001. The operation process is as follows: First, the electronic price tag address data is used as the information field A. If the information segment A is 1100 0100 1010 0101, first shift the information segment left by 16 bits to get the corresponding code of field B as 1100 0100 1010 0101 0000 0000 0000 0000. Then, perform polynomial division on field B and G(x) to get the remainder C with the code 0011 1111 1101 1111. The remainder C is the CRC code of the electronic price tag address 1100 0100 1010 0101.

[0084] Optionally, in this embodiment, the subroutine for calculating the CRC code of the data segment is:

[0085]

[0086]

[0087] where *ptr points to the first byte of the send buffer, and len is the total number of bytes to be sent.

[0088] In this embodiment, when binding the electronic price tag, communication is carried out with the server through the redundancy check code. If the address and redundancy check code of the price tag to be bound are the same as those stored in the server, the price tag is activated and receives the broadcast message of the base station, thereby completing the subsequent picture and update functions. Thus, the unactivated price tags are always in the long sleep state, with extremely low battery consumption, ensuring the battery life.

[0089] In this embodiment, the electronic price tag register stores the address and redundancy check code for communication with the binding server. After the binding handheld device scans the QR code of the electronic price tag and obtains the IP address of the price tag, it sends it to the binding server. After the server conducts data communication with the electronic price tag and the redundancy check code verification is successful, the price tag is activated. If the redundancy check code verification fails, the price tag immediately enters the long sleep state without going through the short sleep cycle to avoid power consumption loss caused by receiving broadcast data from the base station at intervals.

[0090] The beneficial effect of this embodiment is that by scanning the identification code of the price tag, the network address of the price tag is obtained through the identification code; the network address is sent to the server, and a first check value issued by the server is obtained, where the first check value is calculated from the network address and preset parameters; the first check value is sent to the price tag so that the price tag compares the first check value with the second check value stored in itself; if the first check value is the same as the second check value, the price tag is controlled to enter the working state, and if the first check value is different from the second check value, the price tag is controlled to enter the sleep state. An efficient and convenient price tag control scheme is realized, enabling the price tag to perform corresponding sleep or network search control according to the scanning operation of external devices, reducing the human and time costs of price tag configuration, improving the maintainability of the price tag, and enhancing the product power of the price tag.
