detailed description

As shown in FIG. 1, a call forwarding method is applied to a first terminal, including the steps:

S110: Sensing a terminal set existing in the preset range and carrying the same login information as itself.

The same login information may include the same phone number, the same QQ number, the same mailbox, the same WeChat account number, the same unique job number, and the like, and may be used to distinguish the identity information. For example, user A has smart phone 1, smart phone 2, tablet computer, smart TV 1, smart TV 2, and these terminal login names are the mobile phone numbers of user A, then the same login information is user A's mobile phone number, carrying The terminal set of the same login information includes a smartphone 1, a smart phone 2, a tablet computer, a smart TV 1, and a smart TV 2. If not necessary, the terminal set may be pre-formed or updated in a pairing manner, and the ID numbers of various communications and information including a telephone number, a QQ number, and a mailbox may be associated in the pairing process, and the user's face may also be associated. The photo is either the user manually adding the associated terminal device number. The preset range is a preset range, which can be set according to actual needs. For example, when the application scenario is a home, the preset range may be the size of the entire home; when the application scenario is a company, the pre-preparation The range can be the entire company size. The sensing terminal is classified into a terminal set, and the terminal set may include a single or multiple terminals, and may include, for example, a tablet computer, a television, and the like.

S120: Send a user sensing request to the terminal set when receiving the call request of the external network.

The external network may be a mobile communication external network, a wireless communication external network, or the like. For example, in mobile communication, the base station sends a call request to the mobile phone. Here, the mobile phone is the first terminal, and when the mobile phone receives the call request of the external mobile communication external network, the mobile phone sends the user sensing request to the terminal set in step S110. Specifically, the first terminal may send the user sensing request to the terminal set by short-distance communication, such as ZigBee communication, Bluetooth communication, WIFI, and radio frequency.

S130: Send a call transfer request to a terminal that senses a known user when receiving a response from any terminal feedback in the terminal set to sense a known user.

The first terminal sends a user sensing request to the terminal set. When the terminal centrally senses that the terminal senses the known user, the terminal sends a sensing of the known user response message to the first terminal, and when the first terminal receives the sensing, the terminal is notified. When the user answers the message, the call forwarding request is sent to the terminal that senses the known user.

S140: When receiving the allowed call transfer response message, establishing communication with the external network and the terminal sensing the known user respectively.

The external network may specifically refer to a mobile communication network in the environment or a local area network within a certain range, such as a WIF in a certain room. The first terminal sends a call transfer request to the terminal that senses the known user. When the terminal of the known user is allowed to allow the call transfer, the feedback allows the call transfer response message to the first terminal, and the first terminal respectively detects the external network. It is known that the user's terminal establishes communication.

As shown in FIG. 2, a call forwarding method is applied to a second terminal, including the steps of:

S210: Receive a user sensing request sent by the first terminal, where the first terminal and the second terminal carry the same login information.

The first terminal and the second terminal carry the same login information, for example, the same account is registered, the same mobile phone number is registered, and the like.

S220: Determine whether there is a known user in the preset function range in response to the user sensing request.

The preset function range is a preset range. Specifically, it refers to a range that the terminal can cover in realizing its own function. For example, the effective call range of the smart phone is its preset function range, and the viewing angle of the television set. It is the default function range. After the second terminal receives the user sensing request, it determines Whether there are known users within the scope of their own preset functions. Assuming that the second terminal is a television set, after receiving the user sensing request, the television determines whether there is a known user within the viewing angle range of the television in response to the user sensing request. A known user is a legitimate or logged-in user. For example, in A's home, A is a known user, and A's friend B is an unknown user.

S230: When there is a known user in the preset function range, sending a known user response message to the first terminal.

When there is a known user within the preset function range of the second terminal, the second terminal generates and transmits a known user response message to the first terminal.

S240: When receiving the call transfer request sent by the first terminal, generate and push a call request.

When receiving the call transfer request sent by the first terminal, the second terminal generates and pushes the call request to the user.

S250: When the user agrees to answer, establish communication with the external network through the first terminal.

After the push is completed, the second terminal waits to listen for the user feedback operation. When the user agrees to answer the call, the second terminal establishes communication with the external network through the first terminal, that is, the first terminal acts as a relay between the second terminal and the external communication external network. The device implements communication between the second terminal and the external network. Specifically, the listening user feedback operation process may be: 1. Collecting image data of the user. 2. According to the image data, determine whether the user completes the preset operation. 3. If completed, generate and send an agreement to answer the answer to the originating call terminal. The preset operation can reply “OK” for the voice, “√” for the gesture action, or “nod” for the body action.

In the call forwarding method of the present invention, the first terminal and the second terminal are terminals that carry the same login information. When the first terminal receives the call request of the external network, the first terminal senses the known user request to the second terminal, and the second terminal Sensing whether there is a known user in the preset function range, when there is feedback, there is a known user response to the first terminal, the first terminal sends a call transfer request to the second terminal, and the second terminal pushes the call request to the user, when When the user agrees to answer the call, the first terminal establishes communication with the external network and the second terminal respectively, that is, the user communicates with the external network through the second terminal and the first terminal, thereby implementing call transfer between different terminals.

In one embodiment, the step of determining whether there is a known user within the preset function range in response to the user sensing request comprises: performing face recognition on the preset function range in response to the user sensing request; Based on the face recognition result, it is judged whether or not there is a known user.

In the present embodiment, the face recognition method is employed to determine whether there is a known user. Assuming that the second terminal is a television set, when receiving the user sensing request of the first terminal (mobile phone), the television sets the face data in the visible angle range (sector area) in response to the user sensing request, and the collected person The face data is compared with the pre-stored known user face data to determine whether there is a known user.

In one embodiment, the step of determining whether there is a known user within the preset function range in response to the user sensing request comprises: collecting an ambient sound in response to the user sensing request; performing voiceprint recognition on the collected ambient sound, according to the voiceprint The result is identified to determine if there is a known user.

In this embodiment, the voiceprint recognition method is used to determine whether there is a known user. Assuming that the second terminal is a tablet computer, when receiving the user's emotional request of the first terminal (mobile phone), the tablet computer collects the surrounding environment sound in response to the user's sensing request, and collects the collected sound data and the pre-stored known user voiceprint. The data is compared to determine if there is a known user.

As shown in FIG. 3, in one embodiment, after the step of step S230, the method further includes:

S232: Identify the number of unknown users detected in the preset function range.

In this embodiment, not only the known user is sensed, but also an unknown user existing in the environment is detected, and the number of unknown users is detected within the preset function range. The number of unknown users can be pushed to the user to prompt the user to pay attention to the privacy of the current communication; on the other hand, it can also be pushed to the first terminal, so that the first terminal senses the known user in multiple second terminals. When selecting a terminal with better communication privacy, call forwarding is performed. For example, when a mobile phone and a television (both second terminals) sense a known user, the number of unknown users detected in the preset function range is 5, and the mobile phone and the television prompt the user on the one hand. Pay attention to the privacy of the current call. On the other hand, the first terminal will select a device with better communication privacy from the mobile phone and the TV to answer the call request, and then select the mobile phone as the answering terminal of the call transfer.

To further explain the technical solution of the call forwarding method of the present invention in more detail, the above technical solution will be described in detail below using a real application scenario. Assume that the application scenario is that user A returns home from multiple friends. User A has three terminal devices: smart TV X, smart phone Y, and tablet Z. The first terminal is smart phone Y, smart TV X and tablet. The computer Z is a second terminal.

1. The smart phone Y senses a terminal set carrying the same login information (A account information) in the user A home. The television set X and the tablet Z are included in the terminal set.

2. When the smart phone Y receives the external network call request, the smart terminal Y sends a sensing user request to the smart TV X and the tablet Z through WIFI or Bluetooth.

3. When the smart TV X receives the sensing of a known user request, the face recognition technology is used to determine whether there is a known user in the viewing angle range of the television, and when present, the sensing of the known user message to the smart phone is sent; the tablet computer When Z receives the sensing of a known user request, it uses the voiceprint recognition technology to determine whether there is a known user around, and when it exists, it sends a sensing of the known user message to the smartphone. In addition, the smart TV X or tablet also recognizes the number of unknown users around, on the one hand, sends the number of unknown users to the smartphone Y, and on the other hand waits for the user to pay attention to the privacy of the call.

4. When receiving the sensing of the known user message, the smartphone Y sends a call forwarding request to the terminal sensing the known user, and assumes that the smart TV X face recognition senses that the user is currently watching TV, then the smartphone Y sends Call transfer request to smart TV X. If both the smart TV X and the tablet Z sense that a known user exists, the smart phone Y selects a tablet with higher communication privacy as the answering call terminal according to the preset communication privacy level, and sends a call transfer request to the tablet Z. .

5. The smart TV X or tablet Z pushes the call request to the user by voice and/or display mode, and prompts the user to pay attention to the privacy of the call. When the user nods to indicate that he is willing to answer, establish communication between the external network, the smart phone Y, and the smart TV X or the tablet Z, that is, the smart phone Y acts as a relay device, and realizes the smart TV X or the tablet Z and the external network. Communication between.
