     DETAILED DESCRIPTION 
     The invention will now be described in further detail with reference to the accompanying drawings. 
       FIG. 1  shows a schematic diagram of a real-time communication terminal that can be connected by unilateral calls  1  according to one embodiment of the present invention. The real-time communication terminal that can be connected by unilateral calls  1  according to an embodiment of the present invention includes a video capturing unit  101 , an audio capturing unit  102 , a speaker  104 , and a transceiver  105 . The video and audio are collected by the video capturing unit  101  and the audio capturing unit  102 , respectively, and the audio is transmitted through the transceiver  105 . The audio received through the transceiver  105  is output through the speaker  104 . The transceiver  101  automatically issues a response to the connection request in response to receiving a connection request from the user, thereby automatically establishing an IP communication with the user. “Connected by unilateral calls” means that a two-way communication is automatically established after receiving a call. 
     After the transceiver  101  automatically establishes the IP communication with the user, it is possible to automatically establish the two-way communication between the trusted user and the person at the communication terminal that can be connected by unilateral calls  1 . That is, the audio from the trusted user is outputted through the speaker  104  while the video and the audio collected by the video capturing unit  101  and the audio collection unit  102  are transmitted to the trusted user. It is also possible to notify the trusted user only of the situation at the real-time communication terminal  1  without transmitting the audio or the like of the trusted user to the communication terminal that can be connected by unilateral calls  1  side. That is, only the video and audio acquired by the video capturing unit  101  and the audio capturing unit  102  are transmitted to the trusted user. When the trusted user sends a bidirectional communication request, the audio or the like of the trusted user is transmitted to the communication terminal that can be connected by unilateral calls  1  side, that is, the video and audio collected by the video capturing unit  101  and the audio capturing unit  102  are transmitted to the trusted user, and the audio from the trusted user is also output through the speaker  104 . 
     In  FIG. 2 , the video capturing unit  101  is a video camera at the upper end of the real-time communication terminal  1 , but it will be understood by those skilled in the art that it may be other imaging devices located at other positions of the real-time communication terminal  1 . The audio capturing unit  102  is, for example, a microphone of the outer surface of the real-time communication terminal  1 , but may be another audio acquisition device. The speaker  104  is, for example, a player for the outer surface of the real-time communication terminal  1 , but may also be other audio output devices. The transceiver  105  is, for example, an antenna, or other transceiver device, such as a built-in wireless transceiver module. 
     Herein, the communication terminal that can be connected by unilateral calls includes, but is not limited to, any electronic product that can interact with the user through a touch panel, a voice control device, a remote control device, or a keyboard, such as a computer, a tablet computer (PAD), Network television (IPTV), etc. It will be understood by those skilled in the art that other user equipment, if applicable to the present invention, should be included within the scope of the present invention. 
     The communication terminal that can be connected by unilateral calls  1  may further include a display  103  in which, after the transceiver  101  establishes communication with the IP of the trusted user, if the transceiver  105  receives video, then the display  103  displays the video; if the transceiver  105  does not receive the video, then the display displays a icon of the trusted user. Of course, the transceiver  103  may display only the icons of the trusted user even in the case where the video can be received. Wherein the icon of the trusted user may be a video footage, avatar, or other icon of a trusted user. Of course, the communication terminal that can be connected by unilateral calls  1  may not include the display  103 , so that the real-time communication terminal  1  cannot see the image of the trusted user when communicating with the trusted user, and can only hear the voice of the trusted user. 
       FIG. 2( a )  shows a schematic diagram of IP communication between a communication terminal that can be connected by unilateral calls  1  and a single trusted user according to one embodiment of the present invention. According to  FIG. 2( a ) , IP communication is preferably performed based on a point-to-point protocol when the communication terminal  1  perform IP communication with the single trusted user to save the resources of the server.  FIG. 2( b )  shows a schematic diagram of IP communication between a communication terminal that can be connected by unilateral calls  1   1  and a plurality of trusted users according to another embodiment of the present invention. According to  FIG. 2( b ) , when performing IP communication between the communication terminal that can be connected by unilateral calls  1  and the plurality of trusted users, the information is transmitted and received via the server  5  through the IP network  4 . 
     Specifically, in the case of the trusted user A and the trusted user B, the IP communication is directly based on the point-to-point protocol when the real-time communication terminal that can be connected by unilateral calls  1  performs IP communication only with the trusted user A, when the communication terminal  1  has established an IP communication with the trusted user A and the connection request of the trusted user B is received, the communication terminal  1  sends a IP communication request via the server to the trusted user B and then sends a request to the trusted user A for IP communication via the server, after which both the trusted user A and the trusted user B communicate with the real-time communication terminal that can be connected by unilateral calls  1  through the server. The IP communication between the trusted user A and the real-time communication terminal that can be connected by unilateral calls  1  is switched from the point-to-point IP communication mode to the server for IP communication. Here, the server may include a network host, a single network server, a plurality of network server collections, or a cloud computing-based set of computers. 
     Optionally, in the case where the transceiver  105  of the real-time communication terminal that can be connected by unilateral calls  1  communicates with the plurality of trusted users at the same time, the display  103  of the real-time communication terminal that can be connected by unilateral calls  1  may simultaneously display a plurality of trusted user&#39;s video or icon. Preferably, in order to make the real-time communication terminal that can be connected by unilateral calls  1  more freely select the communication party, when one or more videos or icons in the video or icon of the plurality of trusted users is selected, the transceiver  105  of the communication terminal that can be connected by unilateral calls  1  disconnects the IP communication with the trusted user corresponding to the one or more videos or icons. Or the transceiver  105  does not output the selected one or more videos or icons of the corresponding trusted user&#39;s voice while still IP communicating with one or more trusted users, only the display  103  displays the selected one or more videos or identifying the video screen of the corresponding trusted user, and avoiding the interference of the voices of the plurality of trusted users heard by the person at the end of the real-time communication terminal. 
     Optionally, in order to better highlight the main picture in the display  103  of the real-time communication terminal  1 , when one of the videos or icons of the plurality of trusted users is selected, the communication terminal that can be connected by unilateral calls  1 , the video or icon of the selected trusted user is enlarged from the original screen to the large main picture. 
     According to an embodiment of the present invention, to more intelligently remind the trusted user of the case of a real-time communication terminal that can be connected by unilateral calls, in response to a person or a specific person is identified from the video and audio from the video capturing unit  101  and the audio capturing unit  102 , the communication terminal that can be connected by unilateral calls  1  may sends a notification to the trusted user by the transceiver  105 . Typically, when the communication terminal that can be connected by unilateral calls  1  is switched from an environment without any person presented to an environment with someone around, i.e., the video capturing unit  101  and the audio capturing unit  102  detects that a person is present in the current place, the transceiver  105  send a notification to the trusted user at the other end to inform the trusted user that there is someone presented in the current environment. Typically, the real-time communication terminal that can be connected by unilateral calls  1  may also actively send a notification to the trusted user by the transceiver  105  for the specific person identified by the video capturing unit  101  and the audio capturing unit  102 . For example, in the real scenario, a nurse is at home, at that time a boy is returned from school, and the real-time communication terminal that can be connected by unilateral calls  1  at home identify the boy by the video capturing unit  101  and the audio capturing unit  102 , and the transceiver  105  sends a notification in real-time to the remote user (such as the father in the office). 
     Optionally, the real-time communication terminal that can be connected by unilateral calls  1  may identify people or specific people by the video capturing unit  101 , the audio capturing unit  102 , and other devices or units, based on one or more of face recognition, height recognition, voice recognition, and wireless signals issued by the mobile phone. 
     In the case of identifying a person, because the pattern of the human face is very much like that of the vast majority of people, the person&#39;s voice frequency is within a certain range, so that, for example, when a certain area of a captured image is similar to the pattern of the stored face; and/or the distance between the face and the real-time communication terminal  1  sensed by the position sensor and/or the depth sensor indicate that the height of an object is within a certain range; and/or the voice acquired by the audio capturing unit  102  is also within a certain frequency range, the presence of a person is identified. 
     In the case of identifying a specific person, the pattern and/or the height and/or the voice frequency of the person&#39;s face of a specific person may be stored in the storage in advance. When a certain area in the captured image matches the stored pattern of the specific face; and/or the distance between the specific face and the real-time communication terminal that can be connected by unilateral calls  1  detected by the position sensor and/or the depth sensor indicate the height of the person matches with the height of a specific person stored in the storage; and/or the voice acquired by the audio capturing unit  102  matches the frequency of the stored specific person&#39;s voice, the specific person is identified. 
     The existence of a person or a specific person can also be done by self-learning. For example, if a pattern in the captured image always appears at the same time as a certain frequency of the acquired voice, a prompt can be displayed on the display, that is, the person is identified, and the user of the automatic monitoring and autonomous reaction device  1  shall confirm and named the identified person. If the user of the real-time communication terminal  1  indicates that the identified object is not correct, he shall give feedback on the interface of the display of the real-time communication terminal  1 . When this feedback is received, the same captioned image occurring with the same frequency of captured voice is not considered as the present of a person or a specific person. In the self-learning mode, it is also possible to store the patterns of the specific person&#39;s face and/or the height and/or the voice frequency in the storage in advance. 
     In addition, it is also possible to identify people or specific people based on the wireless signals that are sent by the mobile phone. For example, the communication terminal that can be connected by unilateral calls  1  has a Bluetooth device, and the user&#39;s handset also has a Bluetooth wireless unit. It is considered that a specific person is identified when the communication terminal that can be connected by unilateral calls  1  recognizes that the Bluetooth wireless unit of a specific identity is presented in certain distance. 
     Herein, the means for identifying a person or a specific person for a communication terminal that can be connected by unilateral calls I is not limited, and any device or unit having an identifier or a specific person, if applicable, shall be included in the scope of protection of the present invention, and is hereby incorporated by reference herein. 
     Alternatively, the communication terminal that can be connected by unilateral calls  1  may also use the video capturing unit  101 , which recognizes the specific action based on the acquired video and audio, for example, recognizing the action of the old man&#39;s fall, the action of the child dancing etc., and then the transceiver  105  send a notification to the trusted user at the other end. 
     Alternatively, the model may be set up manually and in accordance with the established action. When a specific action matching the one stored model is searched from the video and audio acquired by the video capturing unit  101  and the audio capturing unit  102 , the notification is sent from the transceiver  105  to the trusted user at the other end. for an action to watch TV, create a model: identify a person sitting on the sofa; look along the direction of the person&#39;s eyes, there is an object; identify the object is the TV; the person&#39;s eyes stay on the TV at least  10  seconds. If the person is detected from the image taken from the video capturing unit  101  and then the person is seated on the sofa (the recognition of a sofa is similar to face recognition, it is also possible to perform the pattern matching, or taking the image of a person sitting on the sofa as a whole as a target for pattern matching recognition), and then detect the person&#39;s gaze direction, and then detect whether the object in the direction of the person&#39;s eyes is a TV (for example, the TV as an object to match the pattern), then countdowns  10  seconds. If it reaches  10  seconds, the action of watch TV is detected. 
     Of course, the real-time communication terminal that can be connected by unilateral calls  1  can automatically establish an action model by self-learning such as machine learning. For example, the real-time communication terminal that can be connected by unilateral calls  1  extracts an action feature from the video and audio acquired by the video capturing unit  101  and the audio collection unit  102 , and creates an action model based on the extracted feature. For example, from the video and audio collected by the video capturing unit  101  and the audio collection unit  102 , a person is identified as sitting on the couch, and there is a television in the direction of the person&#39;s eyes, where the person&#39;s eyes remain on the television at least ten second, which exceeds the threshold, then this is considered as a specific action model. In this case, the action model may be stored in the database without being stored in advance, but the model of the action is extracted in a learning manner from the video and the audio collected by the video capturing unit  100  and the audio capturing unit  102 . 
     To more accurately identify a specific action, the real-time communication terminal that can be connected by unilateral calls  1  further comprises a depth sensor ( 197 ). A specific action is identified by the video and audio captured by video capturing unit  101  and the audio capturing unit  102 , and the depth sensed by the depth sensor. The depth sensor measures the distance between a person or an object and a real-time communication terminal that can be connected by unilateral calls. Although as showed in  FIG. 2( a ) , the depth sensor  197  may be located at a position other than the center of the upper frame of the display, and may be provided at other reasonable physical positions. When the person or object has an action, the same magnitude of motion varies depending on the distance from the communication terminal that can be connected by unilateral calls  1  in the captured image. Therefore, combined with the depth sensor, the action can be more accurate identification, thereby enhancing the recognition accuracy. 
     Optionally, the communication terminal that can be connected by unilateral calls  1  detects an abnormal condition from the video and audio collected by the video capturing unit  101  and the audio collection unit  102 , and transmits the notification from the transceiver  105  to the trusted user at the other end. Among them, abnormal conditions such as visit by stranger, fire, crying, noisy, electrical accidents and so on. Typically, the anomaly is identified by identifying one or more of the following: the video capturing unit  101  collects the dramatic changes in the video; the amplitude of audio collected by the audio capturing unit  102  is above a certain threshold; the audio collection unit  102  collects a dramatic change in the audio; a predetermined event is recognized from the video and the audio acquired by the video capturing unit  101  and the audio capturing unit  102  respectively. Predetermined events are pre-defined events such as fire, electrical accidents and so on. 
     Specifically, the communication terminal that can be connected by unilateral calls  1  recognizes a predetermined event is recognized from the video and the audio acquired by the video capturing unit  101  and the audio capturing unit  102  respectively, wherein by searching the video and audio acquired by the video capturing unit  101  and the audio capturing unit  102  separately for the event matching with the established model to identify a predetermined event. Here, the communication terminal that can be connected by unilateral calls  1  can automatically establish a model of a predetermined event by self-learning such as machine learning. Typically, the real-time communication terminal that can be connected by unilateral calls  1  extracts event characteristics from the video and audio acquired by the video capturing unit  101 , the audio collection unit  102 , and establishes a model of a predetermined event based on the extracted event characteristics. Of course, in additional to using the self-learning method to establish a predetermined event model, the user may also specify a number of predetermined events model. 
       FIG. 3  shows an external left view of a real-time communication terminal that can be connected by unilateral calls according to one embodiment of the present invention. According to an embodiment of the present invention, in order to collect information better, the real-time communication terminal that can be connected by unilateral calls  1  further includes a turning device  199  for rotating the video capturing unit  101 . As shown in figure. It is preferable that the rotation device  199  causes the video capturing unit  101  to rotate in the direction facing the identified element in response to one of the following elements identified in the audio and video acquired by the video capturing unit  101  and the audio collection unit  102 : a person or a specific person; specific action; abnormal condition. 
     In one embodiment, the video capturing unit  101  shown in  FIG. 3  may rotate left or right toward the identified element. In another embodiment, the video capturing unit  101  shown in  FIG. 3  may be rotated up, down, left and right toward the identified elements. 
     As shown in  FIG. 2( a ) , the communication terminal that can be connected by unilateral calls  1  may further include a light sensor  198  for sensing a change in ambient light around the real-time communication terminal  1 , wherein the display brightness of the display  103  is adjusted according to the change of the light. If the surrounding light is strong, you can increase the display brightness of the display. If the surrounding light is weak, you can reduce the display brightness of the display. In this way, you can reduce the discomfort of the eyes to monitor the monitor. 
     Although the light sensor in  FIG. 2( a )  is located at the center of the center of the display, it can also be set at any other reasonable physical location. 
     It is to be understood that the block diagram shown in  FIG. 1  is for illustrative purposes only and is not intended to limit the scope of the invention. In some cases, certain units or devices may be added or reduced depending on the circumstances. 
     It is to be noted that the above-mentioned communication terminal that can be connected by unilateral calls  1  transmits the notification to the trusted user based on the transceiver  105  by sending a message, such as a text message, a flying letter or a WeChat or a customized message under a private protocol, to the trusted user. 
     In this case, the trusted user at the other end communicates with the real-time communication terminal that can be connected by unilateral calls  1  in the wifi network environment, and of course, the trusted user at the other end can also communicate with each other through a network such as a 3G network, 2G network, 4G, and the like, and the communication terminal that can be connected by unilateral calls  1  is in communication with each other. 
     According to another embodiment of the present invention, as shown in  FIG. 4 , there is provided a tool  31  mounted on a mobile terminal  3  including a transmitting unit  301  and a receiving unit  302 . As shown in Fig. The transmitting unit  301  is configured to transmit a connection request for a specific communication terminal (corresponding to the real-time communication terminal that can be connected by unilateral calls) in response to the first trigger. The receiving unit  302  is configured to receive an automatic response from the specific communication terminal so as to automatically establish an IP communication with the specific mobile terminal. The mobile terminal includes an electronic device such as a smartphone, a tablet computer, etc., which may be installed on a mobile terminal as an APP and displayed in the form of an application icon, which may also be implemented as a plug In the form of built-in mobile terminal. When the mobile terminal is in a network environment such as 2G or the like, the mobile terminal can transmit a notification to the mobile terminal when the mobile terminal is in a network environment such as 2G or so when the mobile terminal is in a network environment such as wifi or 3G or 4G. 
     After the automatic establishment of the IP communication with the specific mobile terminal, the transmitting unit  301  can transmit audio to the specific communication terminal while the receiving unit  302  receives video and audio from the specific communication terminal. After receiving the IP communication with the specific mobile terminal, the receiving unit  302  can receive the audio of the user from the specific communication terminal, and the transmission unit  301  does not transmit the audio of the user. In response to the second trigger, the receiving unit  302  receives the audio and video from the specific communication terminal, at the same time, the transmission unit  301  transmits audio to the specific communication terminal. In this way, if the user of the mobile terminal  3  does not want the person of the specific communication terminal to know that he is monitoring the specific communication terminal, the second trigger may not be performed, so that only the video and audio from the specific communication terminal are transmitted to the mobile terminal  3  The audio of the user of the mobile terminal  3  is not transmitted to the specific communication terminal. 
     The first trigger comprises any of the following: the activation of the mobile terminal; the activation of the tool in the mobile terminal; a specific action on the user interface when the mobile terminal is powered on; the mobile terminal is powered on, and the light is sensed by the mobile terminal. 
     When the first trigger is the start-up of the mobile terminal, the communication connection to the real-time communication terminal  1  is automatically performed as the mobile terminal is turned on. This allows the phone to automatically enter the system after the start of a real-time communication terminal that can be connected by unilateral calls  1  in the environment monitoring status, improve user efficiency. 
     In the case where the first trigger is the activation of the tool in the power-on state of the mobile terminal, the specific action on the user interface in the mobile terminal is turned on, or the specific voice is received by the mobile terminal. It is possible to decide whether or not to enter the monitoring state of the environment in which the real-time communication terminal  1  is located, and to increase the user&#39;s flexibility. Specific actions such as sliding, clicking, double clicking, etc., or entering specific content at a specific location on the touch screen. 
     In the case where the first trigger is the light is sensed by the mobile terminal, when the user takes out the mobile terminal from his pocket, the light is sensed and the brightness is increased, then automatically connecting with the real-time communication terminal that can be connected by unilateral calls  1 . Therefore, it is avoided that the resource waste due to the connection resource of the real-time communication terminal that can be connected by unilateral calls  1  is still holded when the user does not wish to monitor the environment in which the real-time communication terminal  1  is located and the mobile terminal is placed in the pocket. In this manner, a light sensor is provided in the mobile terminal or tool for sensing the change of light on the surface of the mobile terminal. 
     The second trigger may include any of the following: a specific action on the user interface in the active state of the tool; and a specific voice received in the active state of the tool. A specific action can be a position on the user interface (such as sliding, click, double click, etc.) and so on. For example, the first trigger may be an action on a first icon on the user interface, and the second trigger is an action on a second icon that is different from the first icon on the user interface, and so on. 
     Alternatively, the transmission unit  301  is configured to transmit a connection request for a specific communication terminal selected by the user in response to a user input selection when the mobile terminal stores a connection for a plurality of communication terminals. For example, a list of a plurality of communication terminals may be displayed to a user for selecting. In response to this selection, a connection request is sent to the selected specific communication terminal. 
       FIG. 5  shows a flow chart of a method of real-time communication that can be connected by unilateral calls  2  according to still another embodiment of the present invention. According to  FIG. 5 , the method of real-time communication that can be connected by unilateral calls  2  comprises: 
     Step S 1 , the real-time communication terminal that can be connected by unilateral calls receives the connection request from the trusted user;
