[0046] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention.

[0051] In this embodiment, the call data of the multi-mode headset is obtained by the CPU.

[0052] Step 102: Determine a call mode of the multi-mode headset according to the call data; wherein the call mode includes: DECT and Bluetooth combined call.

[0053] In this embodiment, the multi-mode headset further includes: a mode switching button; the call data includes: call transmission data and call mode data;

[0054] The determining, according to the call data, the call mode of the multi-mode headset includes:

[0055] Judging the call data;

[0056] If the call data is call transmission data, extracting the data type of the call transmission data, and determining the call mode of the multi-mode headset based on the data type;

[0057] If the call data is call mode data, the call mode of the multi-mode headset is determined based on the call mode data; wherein the call mode data is generated in response to the user's operation on the mode switching button.

[0058] It can be understood that the CPU identifies the acquired call data. If it is call transmission data, it means that the call has been established at this time, and the call mode is determined according to the type of data transmitted by the call: if the call transmission data is transmitted by the Bluetooth module, the call mode is a Bluetooth call; if the call transmission data is transmitted by the DECT module, the call mode is a DECT call.

[0059] If the call data is call mode data, it means that the call mode is still being selected by the user (the user selects the call mode by pressing the mode switch button), and the call mode is determined according to the mode selected by the user; wherein, the call mode data includes: Bluetooth module activation data, DECT module activation data, Bluetooth and DECT joint activation data; wherein, the Bluetooth module activation data corresponds to Bluetooth calls, the DECT module activation data corresponds to DECT calls, and the Bluetooth and DECT joint activation data corresponds to DECT and Bluetooth joint calls.

[0060] Step 103: When the call mode is a joint call of DECT and Bluetooth, the DECT module is controlled to be disconnected from the first antenna, so that the DECT module transmits signals through the second antenna and the Bluetooth module transmits signals through the first antenna.

[0061] In this embodiment, the call mode also includes: DECT call; the switching control method also includes: when the call mode is DECT call, reducing the transmission power of the Bluetooth module so that the DECT module transmits signals through the first antenna and the second antenna.

[0062] In this embodiment, the call mode also includes: Bluetooth call; the switching control method also includes: when the call mode is Bluetooth call, reducing the transmission power of the DECT module so that the Bluetooth module transmits signals through the first antenna.

[0063] In this embodiment, the multi-mode headset further includes: an antenna combiner; wherein the first antenna is connected to the Bluetooth module and the DECT module through the antenna combiner;

[0064] When the call mode is a combined call of DECT and Bluetooth, controlling the DECT module to be disconnected from the first antenna includes:

[0065] When the call mode is a joint call of DECT and Bluetooth, an antenna disconnection signal is generated;

[0066] The antenna disconnect signal is transmitted to the antenna combiner so that the antenna combiner disconnects the DECT module from the first antenna according to the antenna disconnect signal; wherein, if the antenna combiner does not receive the antenna disconnect signal, the antenna combiner maintains the connection between the DECT module and the first antenna.

[0067] In a specific embodiment, Figure 3 As shown, the working state of the multiplexed antenna is adjusted according to the connection status of the wireless module of the device; an antenna combiner is used in the circuit to connect the Bluetooth module and the DECT module to the same antenna; when DECT is connected but Bluetooth is not connected, antenna 1 (i.e., the first antenna described in the present invention) and antenna 2 (i.e., the second antenna described in the present invention) are both used by the DECT module; when DECT is not connected but Bluetooth is connected, antenna 1 is used by the Bluetooth module, and the DECT module is disconnected from antenna 1 and antenna 2; antenna 1 and antenna 2 can be distributed in both ears.

[0068] In a specific embodiment, DECT uses dual antennas because the dual antenna design can reduce interference and ensure a very large receiving range. The use range of DECT is much greater than that of Bluetooth.

[0069] At the same time, because the headset is very small, there is not much space to install the antenna. In order to ensure the strength and range of the DECT signal, dual antennas are required. There is not enough space for the remaining Bluetooth antenna, so the Bluetooth module and the DECT module share one antenna.

[0070] See also Figure 2 , Figure 2 It is a structural diagram of a switching control device for a multi-mode headset provided by an embodiment of the present invention, comprising: a data acquisition module 201, a call mode module 202 and a joint control module 203;

[0071] The data acquisition module 201 is used to acquire call data of the multi-mode headset; wherein the multi-mode headset transmits call data through a communication module; the communication module includes: a first antenna, a second antenna, a Bluetooth module and a DECT module; the first antenna is connected to the DECT module and the Bluetooth module respectively, and the second antenna is connected to the DECT module;

At this time, based on the connection relationship of the multi-mode headset communication module, the DECT module transmits signals through the second antenna, and the Bluetooth module transmits signals through the first antenna, thereby ensuring that the DECT module and the Bluetooth module do not share an antenna when operating at the same time, thereby avoiding the signal interference problem that occurs when multiple communication modules of the multi-mode headset use antennas at the same time. Furthermore, when the present invention confirms that the communication mode of the multi-mode headset is a DECT call or a Bluetooth call, there is only one module making a call at this time, so it can be ensured that there is no signal interference between the two modules by reducing the transmission power of the module that is not making a call.

[0086] Embodiment 2

[0087] Based on the first embodiment, this embodiment also includes other structures of the multi-mode headset: Figure 4 As shown, it also includes: lithium battery, DSP, microphone, speaker, USB module and optional configuration module;

[0088] The microphone is used to collect the user's voice information;

[0089] The speaker is used to play the transmitted sound information;

[0090] Lithium batteries are used to power the device;

[0091] DSP (Digital Signal Processing) refers to digital signal processing technology, and DSP chip refers to the chip that can implement digital signal processing technology;

[0092] The DECT module is used to connect to a DECT base station via DECT communication;

[0093] The Bluetooth module is used to connect to the mobile phone via Bluetooth communication;

[0094] The USB module is used to connect to a computer (PC) via USB communication.

[0095] In this embodiment, the headset includes a configuration selection module for receiving a mode setting instruction from the user, and setting the working mode of the multi-mode headset: Mode 1: DECT, Mode 2: Bluetooth, Mode 3: DECT+BT for establishing a multi-party conference or one-way talk and one-way hold, and Mode 4: USB. The configuration selection instruction comes from the headset button, PC control software (Yealink USBConnect), mobile phone control software, WH65Base touch screen or button.

[0096] Mode 1: DECT connected to WH65Base or DECT dongle or W80B DECT base station.

[0097] Mode 2: Connect to the mobile phone's Bluetooth and you can answer Bluetooth calls.

[0098] Multiple modes can work simultaneously, such as DECT+BT (Bluetooth),

[0099] When multiple modes are working at the same time, DECT takes priority. When dialing, it detects whether DECT is connected. If DECT is connected, it uses DECT for dialing. It supports multi-mode working at the same time. If there is a Bluetooth call and a DECT call comes in, the headset rings to remind you of the call. After answering the DECT call, the Bluetooth call is in Hold state. It can also realize DECT+Bluetooth+USB call conference mixing.

[0100] Monitor the DECT or Bluetooth wireless module for a long time without connection (10 minutes), and automatically shut it down to improve battery life.

[0101] In a specific embodiment, the mode selection can also identify the current position of the headset through Bluetooth Beacon positioning technology, confirm the distance between the headset and the DECT base station based on Bluetooth, and when the headset is found to enter the DECT working area through Bluetooth, turn on the DECT module and switch the headset to DECT mode or BT+DECT mode. The selection configuration module is controlled by the user or the headset position. When roaming outside the DECT wireless range, the user can still use the same headset to make / receive calls on the mobile phone.

[0102] The Beacon module can be set on the DECT base station. The base station containing the Beacon module continuously sends Bluetooth signals to the surroundings (including the same UUID. When there are multiple identical UUIDs in one area, other information can be attached to distinguish them). When the headset enters the set area, it can receive the signal, and the headset locates, receives and feedbacks the signal. When the DECT base station receives the feedback signal, it means that the headset has entered the DECT area. At this time, the headset is in the DECT area and the DECT module is turned on. The DECT module consumes more power, and it is difficult for users to turn off the DECT module when they leave the office area. Adding a Beacon module to the base station or arranging it in the office can locate the position of the headset.

[0103] In a specific embodiment, see Figure 5 , Figure 5 The product form provided for this embodiment can realize the commercial and home use of the headset. Users in an office environment usually have a personal computer and a wired phone on the table. The headset base is a DECT base station coupled to a personal computer or a phone. The headset base includes a wireless transceiver that uses the DECT protocol. The headset base wireless transceiver has a base wireless communication range and communicates with the associated headset. Conference rooms and tea rooms in the office area are all within the wireless communication range, and the parking lot is outside the wireless communication range. When the user leaves the company with the headset, such as arriving at the parking lot, the DECT will automatically shut down if there is no connection for a long time. When the user returns to the company, the Beacon module recognizes that the Bluetooth device has returned to the area, and it will turn on the DECT module to connect it again (ordinary Bluetooth headsets or DECT headsets will only sleep after being disconnected, and will not shut down, so the Bluetooth headset will automatically connect when it returns to the range again).

[0104] To better explain, DECT: Digital Enhanced Cordless Telecommunications (DECT) system is an enhanced digital cordless telephone standard developed by the European Telecommunications Standards Institute. It is an open, evolving digital communication standard mainly used for cordless telephone systems. It can provide a framework for high-quality voice and data services for high-density, small-scale communications.

[0105] USB: Universal Serial Bus (English: Universal Serial Bus, abbreviation: USB) is a serial bus standard and a technical specification for input and output interfaces. It is widely used in information and communication products such as personal computers and mobile devices, and has been extended to other related fields such as photographic equipment, digital televisions (set-top boxes), and game consoles.

[0106] Multi-mode (DECT+BT+USB) is factory configurable. For example, if the DECT frequency band is not supported in China, the factory will write different configuration files through dedicated software (same headset software, different configuration files) to disable the DECT baseband and only support Bluetooth and USB modes to comply with local laws and regulations.

[0107] The process of using multimode headsets by customers includes:

[0108] 1. You can choose to turn off / on Bluetooth, USB, and DECT through the Yealink USB Connect software to improve battery life (customers cannot turn on modules disabled by the factory);

[0109] 2. Customers can also turn the module on / off by pressing the mode switch button.

[0110] 3. If the wireless module is not connected for a long time, it will automatically shut down to improve battery life.

[0111] The charging methods of multi-mode headsets include:

[0112] 1. The headset can be charged via USB.

[0113] 2. Place the headset on the DECT base station and charge it through the contacts.

[0114] The software upgrade for the multi-mode headset includes:

[0115] 1. Use Yealink USB Connect software to upgrade the headset software. Yealink USB Connect software is a device management and device software upgrade software developed by Yealink.

[0116] 2. Place the headset on the DECT base station and upgrade the headset software through contact connection.

[0117] Through this embodiment, different modes can be switched and controlled according to the multi-mode headset, so that the multi-mode headset is suitable for different scenarios.

[0118] Embodiment 3

[0119] See also Figure 6 ,like Figure 6 As shown, this embodiment discloses a DECT&BT dual-mode communication system consisting of two parts: a "DECT&BT dual-mode radio frequency link" and a "DECT&BT multi-frequency antenna".

[0120] 1. The DECT&BT dual-mode RF link is composed of "BT chip + DECT chip + filter combiner":

[0121] BT chip: The BT chip contains Bluetooth module, RF transceiver, processor, memory and other components. It can perform BT wireless communication normally.

[0122] DECT chip: The DECT chip contains DECT module, RF transceiver, processor, memory and other components, which can perform DECT wireless communication normally;

[0123] Filter combiner: It is composed of "filter + combiner". The filter greatly attenuates the signals other than the main frequency to an acceptable noise floor range (the DECT filter greatly attenuates the RF signals other than the DECT main frequency, and the attenuated RF signals are within the acceptable noise floor range of BT. The BT filter greatly attenuates the RF signals other than the BT main frequency, and the attenuated RF signals are within the acceptable noise floor range of DECT). The DECT and BT signals are then combined into one signal through the combiner. The combiner has the function of isolating the two frequency bands.

[0124] 2. DECT&BT multi-frequency antenna: DECT&BT dual-frequency antenna: An antenna that meets the performance requirements of DECT frequency band (1.88G~1.93G, 1.78G~1.8G), BT frequency band (2.4G~2.48G), efficiency, gain, and bandwidth.

[0125] The DECT&BT dual-mode communication system will have the following three wireless communication working states, none of which will interfere with each other.

[0126] 1. When DECT is working, DECT performs normal wireless communication through the path of "DECT RF Port" + "DECT filter and combiner" + "DECT&BT ANT (antenna)". At the same time, the DECT signal is bifurcated and attenuated to the bottom noise range through the "BT filter in the filter combiner", which will not affect the transmission and reception of BT.

[0127] 2. When BT is working, BT performs normal wireless communication through the path of "BT RF Port" + "DECT filter and combiner" + "DECT&BT ANT". At the same time, the BT signal is bifurcated and attenuated to the bottom noise range through the "DECT filter in the filter combiner", which will not affect the transmission and reception of DECT.

[0128] 3. When DECT and BT work at the same time, they do not affect each other. The working principle is as follows:

[0129] (a) DECT conducts normal wireless communication through the "DECT RF Port" + "DECT filter and combiner" + "DECT&BT ANT" path. At the same time, the DECT signal is bifurcated and attenuated to the noise floor range through the "BT filter in the filter combiner", which will not affect the transmission and reception of BT.

[0130] (b) When BT is working, BT performs normal wireless communication through the path of "BT RF Port" + "DECT filter and combiner" + "DECT&BT ANT". At the same time, the BT signal is bifurcated and attenuated to the background noise range through the "DECT filter in the filter combiner", which will not affect the transmission and reception of DECT.

[0131] This embodiment introduces the "DECT&BT dual-mode communication system design", DECT and BT can share the "RF link and antenna", and when working at the same time, the wireless parameter indicators are normal, the actual communication music playback and voice calls are normal, and there are no abnormal problems such as freezing, packet loss, and electronic sound. It has strong anti-interference ability, ensures high-quality communication, and saves costs, reduces volume, and weight.
