Description

Technical Field

[0001] This invention belongs to the field of network communication, and in particular to a system and method for Bluetooth binding of a phone and a mobile phone based on NFC technology. Background Technology

[0002] Bluetooth devices are common communication devices in people's daily lives. Using Bluetooth devices to pair mobile phones with IP phones, and using the IP phone as a Bluetooth device for the mobile phone, is one use case for IP phones. IP phones are not just phones; they can also be paired with mobile phones, allowing them to function as the phone's voice output device. Users can play music and make and receive phone calls through the phone, which is especially convenient for multi-person conferences where calls need to be played aloud, facilitating cross-device use, mobile office work, and meeting diverse customer needs.

[0003] Currently, the pairing of mobile phones and IP phones requires manual operation by the user. This involves enabling the phone's Bluetooth function, entering the phone's Bluetooth search interface, and simultaneously enabling the IP phone's Bluetooth discovery mode. The user then has to find the IP phone to be paired from a list of numerous Bluetooth devices found on the phone and perform the Bluetooth pairing operation. This process is not only prone to not finding the correct Bluetooth device or selecting the wrong one, but it is also very time-consuming and laborious.

[0004] When binding IP phones to mobile phones, interference or asynchronous operations often prevent the mobile phone from easily finding and binding the IP phone. The main reasons for this problem are as follows:

[0005] 1. The phone detected a large number of Bluetooth devices but could not locate the Bluetooth address of the IP phone that needed to be bound.

[0006] 2. IP phones cannot remain in Bluetooth discoverable mode for extended periods; they must be exited and re-entered Bluetooth discoverable mode. This causes significant inconvenience for users, especially for IP phones in conference rooms or shared offices. Due to frequent user changes, IP phones need to be frequently paired with different mobile phones. Each pairing is not only time-consuming, but the prolonged presence of the IP phone in Bluetooth discoverable mode also increases power consumption. Summary of the Invention

[0007] To address the aforementioned problems in existing technologies, this invention provides a Bluetooth binding system and method for a phone and mobile phone based on NFC technology. The mobile phone can immediately obtain the Bluetooth address and out-of-seat data (OOB) of the IP phone by tapping it to read the NDEF record. This eliminates the need for a lengthy process of searching and displaying a list of Bluetooth devices, allowing the phone to immediately obtain the Bluetooth address of the IP phone and initiate Bluetooth binding with the device at that address.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] In one embodiment of the present invention, a handset-phone Bluetooth binding system based on NFC technology is proposed, the system comprising:

[0010] A mobile phone that supports NFC can immediately trigger the reading of the NDFF record stored in the chip of the NFC tag when the NFC tag on the IP phone is touched, and obtain the Bluetooth MAC address and security OOB data of the IP phone. At the same time, it will automatically initiate Bluetooth security pairing with the Bluetooth MAC address of the IP phone.

[0011] The IP phone's NFC tag is used to detect the phone's NFC field and send a wake-up signal to the IP phone's host; its chip stores the IP phone's Bluetooth MAC address and secure OOB data.

[0012] The host of the IP phone, upon receiving a wake-up signal, sends an HCI command to control its Bluetooth module to enter Bluetooth discoverable mode.

[0013] Furthermore, when the mobile phone lightly touches the NFC tag on the IP phone, the voltage on the NFC field detection GPO pin of its chip changes, thereby generating a wake-up signal, which is sent to the host of the IP phone.

[0014] Furthermore, when a mobile phone lightly touches the NFC tag on an IP phone, the effective distance is no more than 3cm.

[0015] In one embodiment of the present invention, a method for binding a phone to a mobile phone via Bluetooth based on NFC technology is also proposed, the method comprising:

[0016] When an NFC-enabled phone is unlocked and touches the NFC tag on the IP phone, it immediately triggers the phone to read the NDFF record stored in the chip of the NFC tag and obtain the Bluetooth MAC address and security OOB data of the IP phone.

[0017] When the NFC tag of the IP phone detects the NFC field of the mobile phone, it sends a wake-up signal to the IP phone host. After receiving the wake-up signal, the IP phone host sends an HCI command to control its Bluetooth module to enter Bluetooth discoverable mode.

[0018] The mobile phone automatically initiates Bluetooth security pairing with the IP phone's Bluetooth MAC address based on the read Bluetooth MAC address and security OOB data.

[0019] The mobile phone and IP phone can be directly paired and a Bluetooth connection can be established.

[0020] Furthermore, when the mobile phone lightly touches the NFC tag on the IP phone, the voltage on the NFC field detection GPO pin of its chip changes, thereby generating a wake-up signal, which is sent to the host of the IP phone.

[0021] Furthermore, when a mobile phone lightly touches the NFC tag on an IP phone, the effective distance is no more than 3cm.

[0022] In one embodiment of the present invention, a computer device is also proposed, including a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor executes the computer program, it implements the aforementioned method for binding a phone to a mobile phone via Bluetooth based on NFC technology.

[0023] In one embodiment of the present invention, a computer-readable storage medium is also provided, which stores a computer program that executes a method for binding a phone to a mobile phone via Bluetooth based on NFC technology.

[0024] Beneficial effects:

[0025] This invention uses NFC technology to enable Bluetooth pairing between IP phones and mobile phones. Without compromising the security of Bluetooth connections, it greatly simplifies the process of pairing mobile phones with IP phones, making it more convenient for users and improving user satisfaction.

[0030] The principles and spirit of the present invention will now be described with reference to several exemplary embodiments. It should be understood that these embodiments are provided merely to enable those skilled in the art to better understand and implement the present invention, and are not intended to limit the scope of the present invention in any way. Rather, these embodiments are provided to make this disclosure more thorough and complete, and to fully convey the scope of this disclosure to those skilled in the art.

[0031] Those skilled in the art will recognize that embodiments of the present invention can be implemented as a system, apparatus, device, method, or computer program product. Therefore, this disclosure can be specifically implemented in the following forms: entirely hardware, entirely software (including firmware, resident software, microcode, etc.), or a combination of hardware and software.

[0032] This invention provides a Bluetooth pairing system for a mobile phone based on NFC technology. The mobile phone can instantly read the NDEF (NFC Data Exchange Format) record stored in the chip of the IP phone's NFC tag by simply touching it, thereby obtaining the IP phone's Bluetooth MAC address and out-of-seat data (OOB). The mobile phone can immediately obtain the Bluetooth MAC address and initiate Bluetooth pairing with the device at that address without performing a lengthy search and display process for a Bluetooth device list. This eliminates the need for manual device searching and confirmation of the digital security code. Pairing is initiated almost instantly when the phone touches the IP phone. NFC's ultra-short range makes eavesdropping extremely difficult, ensuring secure key transmission for establishing a strong and encrypted, faceless, secure Bluetooth pairing connection. This simplifies the user experience and improves user satisfaction.

[0033] The principles and spirit of the present invention will be explained in detail below with reference to several representative embodiments.

[0034] Figure 1 This is a system architecture diagram of the phone and mobile phone Bluetooth binding system based on NFC technology according to the present invention. Figure 1 As shown, the system includes:

[0035] A mobile phone with NFC functionality can immediately trigger the reading of the NDFF record stored in the chip of the NFC tag when the NFC tag on the IP phone is touched, and obtain the Bluetooth MAC address and secure OOB data of the IP phone. At the same time, it will automatically initiate Bluetooth secure pairing with the Bluetooth MAC address of the IP phone.

[0036] In this invention, a mobile phone that supports NFC functions acts as an NFC card reader and is in an unlocked state.

[0037] In this invention, when a mobile phone lightly touches the NFC tag on an IP phone, the voltage on the NFC field detection GPO pin of its chip changes, such as... Figure 2 As shown, this generates a wake-up signal, which is then sent to the host of the IP phone.

[0038] In this invention, when a mobile phone lightly touches the NFC tag on an IP phone, the effective distance is no more than 3cm.

[0039] In this invention, the ST25TA02K-P manufactured by STMicroelectronics is used. It is a near-field communication tag chip (NFC Tag IC) that conforms to the NFC Forum Type 4 Tag standard and has NFC interaction, data storage and control output functions.

[0040] The NFC tag of the IP phone is used to detect the NFC field of the mobile phone and send a wake-up signal to the host of the IP phone; its chip stores the Bluetooth MAC address and secure OOB data of the IP phone.

[0041] The host of the IP phone, upon receiving a wake-up signal, sends an HCI command to control its Bluetooth module to enter Bluetooth discoverable mode.

[0042] It should be noted that the implementation of this system can refer to the implementation of the methods described below, and repeated details will not be repeated. The term "module" used above can refer to a combination of software and / or hardware that implements a predetermined function. Although the system described in the above embodiments is preferably implemented in software, hardware implementation, or a combination of software and hardware, is also possible and contemplated.

[0043] Based on the same inventive concept, this invention also proposes a method for Bluetooth binding between a phone and a mobile phone based on NFC technology. When the chip of the NFC tag detects an NFC field (the mobile phone is close), the chip of the NFC tag sends a wake-up signal to the host of the IP phone, causing the host of the IP phone to control the Bluetooth module of the IP phone to enter Bluetooth discoverable mode and accept Bluetooth binding initiated by the mobile phone. Figure 3 As shown, the specific steps are as follows:

[0044] 1. When a mobile phone with NFC is unlocked and touches the NFC tag on the IP phone, it immediately triggers the phone to read the NDFF record stored in the chip of the NFC tag (after the phone's NFC is enabled, the internal NFC chip emits an electromagnetic field through the built-in antenna. When the NFC tag on the IP phone enters the effective range of the phone's NFC antenna, it will sense the electromagnetic field emitted by the phone and obtain working energy (field detection). The phone and the NFC tag on the IP phone shake hands, the phone sends a read command, and the tag on the IP phone sends the data back to the phone), and obtains the Bluetooth MAC address and security OOB data of the IP phone.

[0045] 2. When the NFC tag of the IP phone detects the NFC field of the mobile phone, it sends a wake-up signal to the IP phone host. After receiving the wake-up signal, the IP phone host sends an HCI command to control its Bluetooth module to enter Bluetooth discoverable mode.

[0046] 3. Based on the Bluetooth MAC address and security OOB data of the IP phone, the mobile phone automatically initiates Bluetooth security pairing with the Bluetooth MAC address of the IP phone; the mobile phone and the IP phone skip the traditional Bluetooth search and password input steps, directly complete the pairing, and establish a Bluetooth connection.

[0047] For example:

[0048] Samsung FlipZ phone users can enable the phone's NFC function and bring the phone's NFC sensing area within 2 cm of the IP phone's NFC tag. Within 5 seconds, the phone will display a dialog box asking whether to allow pairing with the ALE-500 (4DC2D9).

[0049] Confirmed, the phone ALE-500 (4DC2D9) has appeared in the list of paired devices on the phone, and the music playing from the phone is coming from the IP phone.

[0050] Based on the aforementioned inventive concept, such as Figure 4 As shown, the present invention also proposes a computer device 100, including a memory 110, a processor 120, and a computer program 130 stored in the memory 110 and executable on the processor 120. When the processor 120 executes the computer program 130, it implements the aforementioned method for binding a phone to a mobile phone via Bluetooth based on NFC technology.

[0051] Based on the aforementioned inventive concept, the present invention also proposes a computer-readable storage medium storing a computer program that executes the aforementioned method for binding a phone to a mobile phone via Bluetooth based on NFC technology.

[0052] This invention proposes a phone-to-mobile phone Bluetooth binding system and method based on NFC technology, which achieves the following optimizations and improvements in Bluetooth binding between mobile phones and IP phones:

[0053] 1. Simple and fast: Bluetooth pairing between mobile phone and IP phone can be achieved with just a touch, without having to manually select the phone from the list.

[0054] 2. No conflicts; it will not bind to IP phones that the user unintentionally binds, as manual selection may result in the wrong IP phone.

[0055] 3. Secure communication, short-range Bluetooth pairing establishment, and high resistance to MITM attacks.

[0056] 4. Low power consumption, Bluetooth pairing can be enabled directly.

[0057] While the spirit and principles of the invention have been described with reference to several specific embodiments, it should be understood that the invention is not limited to the disclosed specific embodiments, and the division of aspects does not imply that features in these aspects cannot be combined for benefit; such division is merely for ease of description. The invention is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.

[0058] Regarding the limitation of the scope of protection of this invention, those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of this invention are still within the scope of protection of this invention.
