Description

Technical Field

[0001] The present application relates to the field of access control technology, and in particular to an access control system and method. Background Art

[0002] With the continuous development of Internet of Things technology and the increasing popularization of smart terminals, smart access control has gradually become a new type of smart terminal equipment, and the smart access control system has become an indispensable part of the community.

[0003] The traditional intelligent access control system is to first install an intelligent access control terminal with a camera and digital buttons downstairs in the community unit, and then install a visual intelligent access control terminal with an LCD screen in each owner's home. If a visitor wants to visit the owner, the visitor first needs to enter the room number of the owner's home in front of the access control terminal downstairs in the unit and click the call button. Then the visual access control terminal in the owner's home will receive the visitor's call and ring to remind the owner that there is a visitor. After the owner finds that there is a visitor calling, he needs to immediately run to the visual access control terminal to confirm the visitor's identity by watching the LCD screen, such as turning on the access control intercom function, and further confirm the visitor's intention through dialogue, and then decide whether to open the door; if the owner confirms the visitor's identity, the owner will open the door, otherwise he will not open the door.

[0004] First, in the existing technical solutions, the owner's home must install an indoor video access control terminal and match it with the access control terminal downstairs in the unit before it can be used; secondly, the video access control terminal installed indoors by the owner is generally close to the owner's door. If a visitor calls and the owner happens to be in the bedroom or other place far away from the video access control terminal, then the owner is likely to not hear the visitor's call and thus miss the call. Summary of the invention

[0044] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Obviously, the described embodiments are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0045] Figure 1 is a framework diagram of the access control system provided in the embodiment of the present application, such as Figure 1 As shown, an embodiment of the present application provides an access control system, including an access control platform 1 and at least one 5G mobile terminal 2;

[0046] The access control platform 1 is used to obtain a first call request initiated by the access control terminal 3, and initiate a second call request to each of the 5G mobile terminals 2 corresponding to the first call request, wherein the first call request and the second call request both include a data channel establishment request;

[0047] The 5G mobile terminal 2 is used to obtain the audio and video data and a preset application list transmitted by the access control terminal 3 based on the data channel establishment request after responding to the second call request, and perform access control according to the application list.

[0048] The 5G mobile terminal 2 can also establish data links with various smart terminals (smart speakers, TV boxes, cameras, door locks, doorbells, etc.) other than the access control terminal 3 to achieve 5G VoNR+ real-time communication.

[0049] Among them, 5G VoNR+ refers to the pan-voice capability of superimposing new data channels and audio and video on the basis of 5G VoNR (Voice over New Radio) network, supporting multiple types of data transmission. In VoNR services, there are three air interface bearers, IMS (IP Multimedia Subsystem) signaling bearer, IMS voice bearer and IMS video bearer. In order to support the increased business needs of VoNR+, a new bearer is added, called IMS DC (Data Channel).

[0050] In order to realize 5G VoNR+ real-time communication, this application integrates AIoTel SDK in the access control terminal 3. AIoTelSDK is an intelligent IoT multimedia communication technology that integrates AIoT and Telephony, a low-latency, slow-heartbeat IoT transmission connection protocol, and a lightweight embedded audio and video software development kit.

[0051] Specifically, the access control terminal 3, the access control platform 1 and the 5G mobile terminal 2 use the standard SIP (Session Initiation Protocol) protocol based on UDP (User Datagram Protocol, a message-oriented transport layer protocol) for conversation.

[0052] Figure 2 : is a flow chart of a door access terminal calling a 5G mobile terminal provided in an embodiment of the present application, such as Figure 2As shown, the access control platform 1 obtains the first call request initiated by the access control terminal 3. The first call request signaling may include sip: invite / sdp(dcmap){from: virtual number, to: 1302}, where dcmap is a data channel establishment request, which can be used to call up the factory application preset in the 5G mobile terminal 2, without the need to install and design audio and video software. The virtual number corresponds to the access control terminal 3, and 1302 refers to the detailed address of a certain owner of the community being visited.

[0053] The access control terminal 3 is bound to the residential unit building. After the binding is successful, the access control platform 1 will assign a globally unique virtual number to each access control terminal 3, and then enter the detailed address and mobile phone number of the owner corresponding to the unit building, such as Room 1302, Unit 3, Building 4, and mobile phone number 1886710xxxx (based on the mobile phone numbers reported by the owner, the mobile phone numbers of multiple family members can be entered, such as mobile phone A and mobile phone B). After the information is successfully entered, it will be uploaded to the access control platform 1, and the access control platform 1 will save the owner information to the database.

[0054] After receiving the first call request, the access control platform 1 parses the detailed address of the owner, determines the owner's mobile phone number, and initiates a second call request to each 5G mobile terminal 2. If there are multiple mobile phone numbers, there will be multiple second call requests, such as sending a second call request sip: invite / sdp(dcmap){from: fixed phone number, to: mobile phone number A} to mobile phone A; sending a second call request sip: invite / sdp(dcmap){from: fixed phone number, to: mobile phone number B} to mobile phone B. The fixed phone number is the IMS fixed phone number corresponding to the mobile phone number (the fixed phone number supports concurrent calling function, and the IMS fixed phone number corresponds to multiple mobile phone numbers). The access control platform 1 stores the correspondence between the mobile phone number and the IMS fixed phone number.

[0055] The 5G mobile terminal 2 corresponding to mobile phone number A and mobile phone number B starts ringing after receiving the second call request. The 5G mobile terminal 2 replies sip:183 / sdp to the access control platform 1 respectively to negotiate the establishment of the media channel.

[0056] The visitor enters the owner's room number (such as 1302) in front of the access control terminal 3 downstairs of the corresponding unit in the owner's home (located in Room 1302, Unit 3, Building 4 of a residential community) and clicks the call button on the access control terminal 3. The owner's mobile phone (supporting 5G VoNR+ real-time call service) will receive the 5G VoNR+ call. At the same time, the visitor will hear a ringback tone (customized music played by the access control platform 1) on the access control terminal 3 side, waiting for the owner to answer and open the door.

[0057] Figure 3 is a schematic diagram of the answering interface of the 5G mobile terminal 2 provided in an embodiment of the present application, such as Figure 3As shown, if the owner chooses to answer the 5G VoNR+ call through the 5G mobile terminal 2 corresponding to mobile phone number A (the access control platform 1 will hang up the call from the 5G mobile terminal 2 corresponding to mobile phone number B), the owner can hear the visitor's voice and see the visitor's video screen, but the visitor is unaware of the owner's answering operation and still hears the ringback tone. Since both the access control terminal 3 and the mobile phone support the VoNR+ call service, after the call is established, in addition to negotiating to establish a media channel, an IMS Data Channel is also negotiated to be established for both ends to transmit data other than media streams. The 5G mobile terminal 2 obtains the audio and video data transmitted by the access control terminal 3 and displays the video screen of the visitor of the access control terminal 3 in the upper half of the answering interface. The application list includes function modules such as recording, waiting, adding calls, video calls, mute, 5G new calls, and hang up.

[0058] Figure 4 This is a flow chart of a 5G mobile terminal hanging up a call provided in an embodiment of the present application, such as Figure 4 As shown in the figure, if the owner does not want to communicate with the visitor after seeing the visitor, he can directly choose to hang up the phone, and the hang-up signal sent to the access control platform 1 is sip: bye{from: mobile phone number A, to: landline number}. The hang-up signal sent by the access control platform 1 to the access control terminal 3 is sip: bye{from: 1302, to: virtual number}. The visitor will not know whether the owner is at home, which plays a good role in protecting the owner's privacy.

[0059] Figure 5 is a flow chart of a 5G mobile terminal connecting an incoming call provided in an embodiment of the present application, such as Figure 5 As shown in the figure, if the owner wants to communicate with the visitor and understand the visitor's intention, he can click the 5G new call button on the call interface to enter the 5G VoNR+ new call application list page, that is, the 5G mobile terminal 2 corresponding to mobile phone number A sends a signal to the access control platform 1: sip: 200ok / sdp(dcmap){from: fixed phone number, to: mobile phone number A}. The access control platform 1 sends a signal to the access control terminal 3: sip: 200ok / sdp(dcmap){from: virtual number, to: 1302}.

[0060] Figure 6 is a schematic diagram of an application list interface provided in an embodiment of the present application, such as Figure 6 As shown, the owner can control access through the application list interface.

[0061] It can be understood that, by setting up an access control platform 1 and at least one 5G mobile terminal 2, the present application eliminates the need to install an additional visual access control terminal 3 at home. The 5G mobile terminal 2 can be carried with you, and multiple 5G mobile terminals 2 will give prompts at the same time, reducing the probability of missing a visitor's call.

[0062] Figure 7 is a schematic diagram of the access control interface provided by the embodiment of the present application, such as Figure 7 As shown, in one embodiment, the application list includes at least an intercom function module and a door opening function module, which are used to obtain an intercom control instruction or a door opening control instruction;

[0063] Correspondingly, performing access control according to the application list includes:

[0064] The 5G mobile terminal 2 transmits the intercom control instruction or the door opening control instruction to the access control platform 1 based on the established data channel;

[0065] The access control platform 1 is used to transmit the audio and video data sent by the 5G mobile terminal 2 to the access control terminal 3 after receiving the intercom control instruction.

[0066] Figure 8 is a flowchart of starting docking provided in an embodiment of the present application, Fig. 9 is a flow chart of opening a door provided in an embodiment of the present application, such as Figure 8 and Fig. 9 As shown, the owner clicks on the intercom, and the 5G mobile terminal 2 obtains the intercom control instruction. The intercom message is transmitted to the access control terminal 3 through the data channel. After the access control terminal 3 parses the intercom message from the data channel, it sends a notification (sip: notify) to the capability platform to turn on the intercom. After communication, if the owner refuses to open the door for the visitor, he can directly click the "hang up" button to hang up the current call; if the owner accepts the visitor, he clicks the door opening button, and the 5G mobile terminal 2 obtains the door opening control instruction. The door opening control instruction is transmitted to the access control terminal 3 through the data channel. The access control terminal 3 parses the door opening control instruction from the data channel and executes the door opening operation. After the door is opened successfully, the access control terminal 3 automatically hangs up the current call, and the access control terminal 3 sends a signaling sip: bye{from: virtual number, to: 1302} to the access control platform 1, and the access control platform 1 sends a signaling sip: bye{from: fixed phone number, to: mobile phone number A} to the 5G mobile terminal 2.

[0067] It can be understood that the present application transmits access control signaling through the IMS DC data channel, which has less audio and video transmission delay than the traditional OTT-based access control intercom solution, has high real-time performance and provides a better user experience.

[0068] In one embodiment, the access control platform 1 is further configured to send a preset ringback tone to the access control terminal 3 after receiving the first call request until the intercom control instruction is received.

[0069] After receiving the first call request, the access control platform 1 sends a signaling sip:183 / sdp and a preset ringback tone to the access control terminal 3 .

[0070] After receiving the notification of starting intercom, the access control platform 1 stops sending the customized ringback tone stream to the access control terminal 3 and forwards the audio stream from the mobile phone to the access control terminal 3. At this point, the visitor can hear the owner's voice, and the owner can communicate with the visitor to understand the visitor's intention.

[0071] It is understandable that before the owner responds to this application, the visitor cannot obtain the owner's audio and video information, and cannot determine whether the owner is at home, which plays a good role in protecting the owner's privacy.

[0072] In one embodiment, the application list further includes a hang-up function module for obtaining a hang-up control instruction;

[0073] The 5G mobile terminal 2 transmits the hang-up control instruction to the access control platform 1 based on the established data channel;

[0074] The access control platform 1 is used to disconnect the access control terminal 3 upon receiving the hang-up control instruction.

[0075] The owner can click "Hang up" on the answering interface of the 5G mobile terminal 2 before or after establishing the intercom to issue a hang up control command.

[0076] After issuing the disconnect control command, the 5G mobile terminal 2 sends a signaling sip: bye{from: mobile phone number A, to: landline number} to the access control platform 1, and the access control platform 1 sends a signaling sip: bye{from: 1302, to: virtual number} to the access control terminal 3.

[0077] It can be understood that the present application transmits control instructions through a data channel, which has less audio and video transmission delay than the traditional OTT-based access control intercom solution, has high real-time performance and provides a better user experience.

[0078] In one embodiment, the application list also includes a sharing function module and a call setting function module. The sharing function module is used to realize the sharing of preset content between the 5G mobile terminals 2, and the call setting function module is used to set the call background between the 5G mobile terminal 2 and the access control terminal 3.

[0079] The content sharing module includes screen sharing, file sharing and access control, and the call setting function module includes AR effects and background replacement.

[0080] It can be understood that the present application expands the functions of the access control by setting up a sharing function module and a call setting function module.

[0081] In one embodiment, the access control system also includes an IMS network 4, which is used to forward the second call request to each of the 5G mobile terminals 2 corresponding to different first call requests.

[0082] The IMS network 4 forwards the second call request to all 5G mobile terminals 2 through the 5G base station.

[0083] It is understandable that one IMS account can call multiple different mobile phone numbers at the same time. Therefore, when visitors from different unit buildings call different owners through the unit access control at the same time, they can all call the corresponding owner's mobile phone number through the same IMS account without affecting each other.

[0084] In one embodiment, the access control platform 1 is also used to respond to a login request initiated by the access control terminal 3 based on the first communication protocol and a virtual number registration request initiated by the access control terminal 3 based on the second communication protocol, allocate a virtual account to the access control terminal 3, and register the IMS account corresponding to the virtual account to the IMS network 4.

[0085] Fig.10 is a flowchart of virtual number and IMS account registration provided by the embodiment of the present application, such as Fig.10 As shown, after the access control terminal 3 is powered on and connected to the network successfully, it will first use the HTTPS protocol (carrying device information, such as device ID, etc.) to request virtual account information from the access control platform 1, and then use the standard SIP protocol based on UDP to register the virtual number to the access control platform 1. After receiving the registration request from the access control terminal 3, the access control platform 1 will query the IMS account corresponding to the device virtual number, register the IMS account to the IMS network 4, and keep it online all the time.

[0086] In one embodiment, the access control platform 1 is also used to stop sending the second call request to the other 5G mobile terminals 2 corresponding to the first call request after any of the 5G mobile terminals 2 responds to the second call request.

[0087] For example, if the 5G mobile terminal 2 corresponding to mobile phone number A answers the call, the access control platform 1 sends the signaling sip: 603 {from landline number, to: mobile phone number B} to the 5G mobile terminal 2 corresponding to mobile phone number B.

[0088] It is understandable that multiple 5G mobile terminals 2 will prompt at the same time, reducing the probability of missing visitor calls.

[0089] To sum up, the beneficial effects of the present application include: the owner's home does not need to install an additional visual access control terminal 3 (that is, it saves the procurement cost of the access control system and eliminates the need for operations such as drilling holes and wiring in the owner's home). Instead, the owner's mobile phone and the access control terminal 3 downstairs in the unit are used to communicate to realize operations such as intercom and door opening; when a visitor calls the owner's room number through the access control terminal 3, the owner's 5G mobile phone will ring (if multiple mobile phone numbers are configured, the corresponding mobile phones will ring at the same time). No matter where the owner is at home at this time, as long as the mobile phone is with him, he will not miss the visitor's call (even if owner A's mobile phone is not with him, as long as owner B's mobile phone is with him, he will not miss the visitor's call), thereby greatly reducing the probability of missing the visitor's call; the access control terminal 3 and the 5G mobile phone end use a solution based on 5G VoNR+ real-time communication for communication, with small delay in audio and video stream transmission, clear and smooth video images, and better user experience.
