[0002] Video live streaming is a kind of distributed centralized control network, and in the video live streaming, multiple autonomous domains are distributed by layers, and the overall network structure is formed by interconnection of multiple structural units called autonomous domains. At present, the management of core servers and terminal devices in a single autonomous domain has been realized, and the information of terminal devices in a single autonomous domain can be accessed and configured by the management device in the autonomous domain at any time. However, the access authorization management mechanism of terminal devices in a cross-autonomous domain scenario has not been reasonably defined, and in related technologies, a method of directly inputting a video live streaming number is commonly used to access terminal devices in a cross-autonomous domain.

[0068] The technical solutions in the embodiments of the application will be described clearly and completely below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are some of the embodiments of the application, but not all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the application.

[0069] Figure 1 is a structural schematic diagram of a WebRTC service system according to an embodiment of the application. In Figure 1In the video live streaming service system, three levels of video live streaming servers are included. The first level of video live streaming server is video live streaming server G0. The second level of video live streaming server includes video live streaming server A0, video live streaming server B0 and video live streaming server C0. The third level of video live streaming server includes video live streaming server A1, video live streaming server A2, video live streaming server A3, video live streaming server B1, video live streaming server C1, video live streaming server C2 and video live streaming server C3. The video live streaming servers of multiple levels are connected in a tree structure. A video live streaming server can be connected with a video live streaming terminal or not directly connected with a video live streaming terminal. One video live streaming terminal is directly connected to one video live streaming server. Video live streaming terminal A01-video live streaming terminal A03 are directly connected to video live streaming server A0. Video live streaming terminal A11-video live streaming terminal A13 are directly connected to video live streaming server A1. Video live streaming terminal A31-video live streaming terminal A32 are directly connected to video live streaming server A3. Video live streaming terminal C01-video live streaming terminal C03 are directly connected to video live streaming server C0. Video live streaming terminal C31-video live streaming terminal C32 are directly connected to video live streaming server C3. Of course, the specific structure of the video live streaming service system can also be set according to actual needs. Figure 1 Only as an example.

[0070] In combination Figure 1 , one video live streaming server and multiple video live streaming terminals directly connected under the video live streaming server constitute an autonomous domain of video live streaming. For example, video live streaming server A0 and video live streaming terminal A01-video live streaming terminal A03 directly connected under the video live streaming server A0 constitute an autonomous domain corresponding to the video live streaming server A0. For another example, video live streaming server A1 and video live streaming terminal A11-video live streaming terminal A13 directly connected under the video live streaming server A1 constitute an autonomous domain corresponding to the video live streaming server A1.

[0071] One video live streaming server is only responsible for managing each video live streaming terminal directly connected under the video live streaming server. Here, the management mainly refers to the modification of configuration information and the like. One video live streaming server cannot manage the video live streaming terminals directly connected under other video live streaming servers. However, in some business scenarios, the video live streaming server needs to perform cross-domain operations, such as inviting video live streaming terminals in other video live streaming domains to join a video live streaming conference under the video live streaming server. The operations of the video live streaming server on the video live streaming terminals in other video live streaming domains due to business needs are mainly read-only operations, that is, only the joining of the conference, the transmission of data and the like can be invited, and the modification of the configuration information cannot be realized.

[0072] The method for cross-domain access to a video live streaming terminal of the present application is applied to Figure 1 the video live streaming server. Figure 2 is a flowchart of a method for cross-domain access to a video live streaming terminal according to an embodiment of the present application. Referring to Figure 2The method for cross-domain access to a video conference terminal according to the present application can comprise the following steps:

[0073] Step S21: determining a target video conference terminal requiring cross-domain access, and a second video conference server in a video conference domain to which the target video conference terminal belongs.

[0074] In the present embodiment, the first video conference server is any one of the video conference servers in the video conference service system, and the video conference domain is a video conference autonomous domain.

[0075] The target video conference terminal can be determined according to user operation or automatically determined by the first video conference server according to business requirements.

[0076] Each video conference terminal belongs to only one video conference autonomous domain and is connected to only one video conference server. Therefore, after the target video conference terminal requiring cross-domain access is determined, the second video conference server in the autonomous domain to which the target video conference terminal belongs can be determined.

[0077] The method for cross-domain access to a video conference terminal according to the present application can be applied to at least two scenarios: 1. a communication scenario between video conference terminals in different autonomous domains; and 2. a video conference scenario among multiple video conference terminals in different autonomous domains.

[0078] For the first scenario, for example, if terminal X under the first video calling server wants to have a video call with terminal Y under the second video calling server, terminal X can send a video call request with terminal Y to the first video calling server. At this time, the first video calling server can determine that the target video calling terminal that needs to be accessed across domains is terminal Y, and terminal Y belongs to the second video calling server according to the video call request. If active sending of a video call request by a terminal is not supported in this scenario (that is, active control by the first video calling server of which two terminals to have a video call), when the first video calling server determines that terminal X under the first video calling server and terminal Y under the second video calling server need to have a video call, the first video calling server can determine that the target video calling terminal that needs to be accessed across domains is terminal Y, and terminal Y belongs to the second video calling server. For the second scenario, for example, if terminal X under the first video calling server wants to start a video conference, a conference initiation request (the list of participants in the conference initiation request includes terminal X, terminal Y and terminal Z under the second video calling server) can be sent to the first video calling server. Then, the first video calling server can determine that terminal Y and terminal Z are target video calling terminals that need to be accessed across domains, and terminal Y and terminal Z belong to the second video calling server. If active sending of a conference initiation request by a terminal is not supported (that is, active control by the first video calling server of which terminals to have a video conference), when the first video calling server determines that terminal X under the first video calling server, terminal Y and terminal Z under the second video calling server need to have a video conference, the first video calling server can determine that the target video calling terminals that need to be accessed across domains are terminal Y and terminal Z, and terminal Y and terminal Z belong to the second video calling server.

[0079] Step S22: Send an access authorization request for the target video calling terminal to the second video calling server.

[0080] In this embodiment, the access authorization request contains the identification (for example, a video calling number) of the target video calling terminal, and the purpose of sending the access authorization request to the second video calling server is to make the second video calling server grant the first video calling server the right to access the target video calling terminal.

[0081] Step S23: Receive terminal information of the target video calling terminal returned by the second video calling server after allowing access authorization.

[0082] In this embodiment, after receiving the access authorization request for the target video calling terminal, the second video calling server can choose to grant the first video calling server the right to access the target video calling terminal, or refuse to grant the first video calling server the right to access the target video calling terminal.

[0083] If the second vision network server grants the first vision network server the right to access the target vision network terminal, the terminal information of the target vision network terminal is returned to the first vision network server. The terminal information mainly includes basic information of the target vision network terminal, such as the duration of the granted right, the effective time of the right, the invalid time of the right, the vision network number, the terminal type, etc. The terminal information can be set according to actual needs, and this embodiment does not make a specific limitation.

[0084] If the second vision network server refuses to grant the first vision network server the right to access the target vision network terminal, a message of authorization failure can be returned to the first vision network server.

[0085] Step S24: According to the terminal information, the target vision network terminal is added to the read-only operation list. Each vision network terminal in the read-only operation list is a vision network terminal on which the vision network server can only perform read-only operations.

[0086] In this embodiment, the vision network server is provided with an operable terminal list. The operable terminal list can be divided into a configurable list and a read-only operation list. Each vision network terminal in the configurable list is a terminal on which the vision network server can modify the configuration information. Each vision network terminal in the read-only operation list is a vision network terminal on which the vision network server cannot modify the configuration information and can only perform read-only operations.

[0087] Since the target vision network terminal is not a terminal in the vision network domain to which the first vision network server belongs, the first vision network server can only perform read-only operations on the target vision network terminal. Therefore, the first vision network server can add the target vision network terminal to the read-only operation list according to the terminal information (such as the vision network number) of the target vision network terminal.

[0088] After adding the target vision network terminal to the read-only operation list, the first vision network server can perform read-only operations on the target vision network terminal according to actual business.

[0089] For example, in combination with Figure 1 The vision network server A0 determines the target vision network terminal C31 that needs to be accessed across domains, and sends an access authorization request for the vision network terminal C31 to the vision network server C3. After receiving the access authorization request, if the vision network server C3 allows the vision network server A0 to access the vision network terminal C31, the vision network server C3 returns the terminal information of the vision network terminal C31 to the vision network server A0. Then, the vision network server A0 adds the vision network terminal C31 to the read-only operation list, and can subsequently perform read-only operations on the vision network terminal C31.

[0090] In this embodiment, when the first vision network server accesses the target vision network terminal under the second vision network server across domains, the second vision network server decides whether to authorize the first vision network server to access the target vision network terminal through negotiation with the second vision network server. Since the second vision network server will detect the information of the target vision network terminal before deciding to authorize, it is determined that the target vision network terminal is legal and safe. Only when the target vision network terminal is legal and safe, the first vision network server is authorized to access the target vision network terminal. Compared with the method in the related art that the first vision network server directly accesses the target vision network terminal through the vision network number of the target vision network terminal, the method can realize the safe access of the first vision network server to the vision network terminal across domains.

[0091] The method for accessing the vision network terminal across domains provided in the present application first determines the target vision network terminal that needs to be accessed across domains and the second vision network server in the vision network domain to which the target vision network terminal belongs. Then, an access authorization request for the target vision network terminal is sent to the second vision network server, and terminal information of the target vision network terminal returned by the second vision network server after allowing access authorization is received. Next, according to the terminal information, the target vision network terminal is added to the read-only operation list, and subsequent read-only operations can be performed on the target vision network terminal. The present application provides a secure authorization mechanism for accessing the vision network terminal across domains. When accessing the vision network terminal across domains, the vision network server of the vision network domain to which the vision network terminal to be accessed belongs is negotiated, and the vision network server decides whether to authorize access (for example, the vision network server can authorize when the vision network terminal is safe and legal), thereby realizing the safe access to the vision network terminal across domains and providing protection for the security of the inter-domain vision network service.

[0092] In combination with the above embodiments, in an implementation manner, determining the target vision network terminal that needs to be accessed across domains and the second vision network server in the vision network domain to which the target vision network terminal belongs can specifically include:

[0093] Determining the second vision network server and the number of target vision network terminals connected under the second vision network server that need to be accessed across domains.

[0094] On this basis, sending an access authorization request for the target vision network terminal to the second vision network server can specifically include:

[0095] Sending an access authorization request containing the number of target vision network terminals to the second vision network server, so that the second vision network server selects target vision network terminals meeting the number from the plurality of vision network terminals directly connected to the first vision network server.

[0096] In the embodiment, the first vision network server can either actively specify the target vision network terminal that needs to be accessed across domains, or only determine the second vision network server and the number of target vision network terminals that the second vision network server needs to provide, and the second vision network server automatically selects the terminals meeting the number from the vision network terminals directly connected thereto as the target vision network terminals and returns them to the first vision network server according to its own situation.

[0097] In some implementation scenarios, the first vision network server only needs to use a preset number of vision network terminals under a specified vision network server, but does not limit a specific part of the vision network terminals, at this time, the first vision network server can take the specified vision network server as the second vision network server, and send an access authorization request containing the number of target vision network terminals to the second vision network server. After the second vision network server receives the access authorization request, it is detected that the vision network number of the specified target vision network terminal is not given, but the number of the target vision network terminal required is given, so the accessible vision network terminals (the accessible vision network terminals generally refer to the safe and legal vision network terminals) meeting the number are selected from the vision network terminals directly connected to itself as the target vision network terminals. Then, the second vision network server returns the terminal information of the target vision network terminal to the second vision network server.

[0098] In the embodiment, if the access authorization request sent by the first vision network server does not give the specified target vision network terminal, the second vision network server can actively select the accessible vision network terminal meeting the number requirement in the access authorization request as the target vision network terminal according to its own situation, thereby improving the flexibility of the cross-domain access of the vision network terminal.

[0099] In combination with the above embodiments, in an implementation, after adding the target vision network terminal to the read-only operation list, the cross-domain access method of the vision network terminal of the present application can further include:

[0100] adding the target vision network terminal to the created vision network video conference.

[0101] In the embodiment, the cross-domain access method of the vision network terminal can be applied to the scenario of cross-domain establishment of the vision network video conference.

[0102] For example, in combination with the above embodiments, in an implementation, the cross-domain access method of the vision network terminal of the present application can further include: Figure 1For example, taking inviting all the WebRTC terminals under WebRTC server C3 to participate in the WebRTC video conference created on WebRTC server A0 as an example, WebRTC server A0 sends a conference invitation to WebRTC server C3, where the number of participating WebRTC terminals (all the WebRTC terminals under WebRTC server C3) and conference information (conference number, start time, end time, etc.) are carried. WebRTC server C3 allows WebRTC terminal C31 and WebRTC terminal C32 to participate in the conference, and returns the terminal information of WebRTC terminal C31 and WebRTC terminal C32 to WebRTC server A0 respectively. WebRTC server A0 adds WebRTC terminal C31 and WebRTC terminal C32 to the read-only operation list, and only when WebRTC terminal C31 and WebRTC terminal C32 are both in the read-only operation list, WebRTC server A0 can perform read-only operation on them. After reaching the start time of the conference, WebRTC server A0 actively pulls WebRTC terminal C31 and WebRTC terminal C32 into the video conference.

[0103] Through the embodiment, the WebRTC terminal can join the cross-domain WebRTC video conference, which enriches the WebRTC function and better meets the business needs of users.

[0104] In combination with the above embodiments, in an implementation, the terminal information of the target WebRTC terminal includes an effective time period in which the second WebRTC server authorizes the first WebRTC server to access the target WebRTC terminal. On this basis, after adding the target WebRTC terminal to the read-only operation list, the method for the cross-domain access WebRTC terminal of the application can include:

[0105] When the invalid time corresponding to the effective time period is reached, the target WebRTC terminal is deleted from the read-only operation list.

[0106] In the embodiment, the effective time period in which the first WebRTC server accesses the target WebRTC terminal is set by the second WebRTC server. The effective time period includes an effective time and an invalid time, and the length of the effective time period is an effective length. The first WebRTC server can only perform read-only operation on the target WebRTC terminal within the effective length, and when the invalid time is reached, the first WebRTC server will automatically delete the target WebRTC terminal in the read-only operation list.

[0107] For example, WebRTC server C3 grants WebRTC server A0 to access WebRTC terminal C31, the effective time is 10:00:00 of the day, and the invalid time is 12:00:00 of the day. Then, WebRTC server A0 can add WebRTC terminal C31 to the read-only operation list

[0108] between 10:00:00 and 12:00:00 of the day, pull WebRTC terminal C31 into the created video conference, and when 12:00:00 is reached, automatically delete WebRTC terminal C31 in the read-only operation list.

[0109] Delete the video call terminal C31 from the read-only operation list.

[0110] Through the embodiment, the video call server can strictly manage each cross-domain video call terminal, and provides a guarantee for the security processing of inter-domain video call services.

[0111] In combination with the above embodiments, in an implementation, the method for accessing a video call terminal across domains of the application can further include:

[0112] When the terminal information of the target video call terminal returned by the second video call server after the access authorization is allowed is not received, the video call terminal that can be allowed to access returned by the second video call server is received.

[0113] In response to the operation of the user, one or more video call terminals are determined from the video call terminals that can be allowed to access, and an access authorization request for the determined video call terminals is sent to the second video call server.

[0114] In the embodiment, after receiving the access authorization request sent by the first video call server, if the first video call server is refused to be granted the right to access the target video call terminal, in addition to returning a message of authorization failure to the first video call server, the second video call server can also return the video call terminals that can be allowed to be authorized to access except the target video call terminal to the first video call server.

[0115] In this way, the first video call server can select one or more video call terminals from all the returned video call terminals that can be allowed to access according to the operation of the user, and then send an access authorization request to the second video call server again, taking the selected video call terminals as target video call terminals. Of course, the first video call server can also select one or more video call terminals from the remaining video call terminals except the returned video call terminals that can be allowed to access according to the operation of the user, and take the selected video call terminals as target video call terminals.

[0116] In the embodiment, after the second video call server refuses to grant the first video call server the right to access the target video call terminal, the second video call server can return the video call terminals that can be allowed to be authorized to access except the target video call terminal to the first video call server, so as to facilitate the selection of the first video call server, and provide convenience for the first video call server to access the video call terminals under the second video call server across domains.

[0117] In combination with the above embodiments, in an implementation, the operation identifier of the current authorization request event is included in the access authorization request. After the target video call terminal is added to the read-only operation list, the method for accessing a video call terminal across domains of the application can further include:

[0118] The second video call server is sent a request for changing authorized access containing the operation identifier, so that the second video call server modifies terminal information of the target video call terminal corresponding to the operation identifier, or cancels the authorization request event corresponding to the operation identifier.

[0119] In this embodiment, the first video call server generates an operation identifier each time it generates an access authorization request, and the operation identifier uniquely corresponds to the authorization request event. In other words, the operation identifier can be understood as a unique number of an authorization request event, and can be used to distinguish other authorization request events.

[0120] The first video call server sends an access authorization request to the second video call server for the first time, and the access authorization request contains an operation identifier. The second video call server stores the operation identifier in the access authorization request.

[0121] In the subsequent process, the first video call server can also send a request for changing authorized access containing the operation identifier to the second video call server for the authorization request event that has been processed and authorized. The request for changing authorized access can be of two types: modifying terminal information of the target video call terminal and canceling the authorization request event.

[0122] For the request of the type of modifying terminal information of the target video call terminal, the content in the request generally includes: the field to be changed and the changed content, etc. The second video call server can determine the authorization request event according to the operation identifier, and then modify the terminal information of the target video call terminal based on the content in the request for changing authorized access.

[0123] For the request of the type of canceling the authorization request event, the second video call server can determine the authorization request event according to the operation identifier, and then cancel the authorization request event.

[0124] On this basis, the method for cross-domain access to a video call terminal of the present application can further include:

[0125] A processing result returned by the second video call server in response to the request for changing authorized access is received.

[0126] If the processing result is that the authorization request event corresponding to the operation identifier is successfully canceled, the target video call terminal is deleted from the read-only operation list.

[0127] In this embodiment, if the first vision networking server sends a cancel authorization request event type request to the second vision networking server, upon receiving the processing result returned by the second vision networking server that successfully cancels the authorization request event corresponding to the operation identifier, the first vision networking server deletes the target vision networking terminal from the read-only operation list. Conversely, if the processing result returned by the second vision networking server that fails to successfully cancel the authorization request event corresponding to the operation identifier is received, the first vision networking server does not process the target vision networking terminal in the read-only operation list.

[0128] For example, in combination with Figure 1 If the vision networking server A0 sends an access authorization request (creates an authorization request event) to the vision networking server C3 at 10:00:00 on October 1, the content in the access authorization request is mainly: requesting the vision networking server C3 to grant the vision networking server A0 the right to invite the vision networking terminal C31 to participate in the video conference X from 14:00:00 on October 1 to 16:00:00 on October 1. The operation identifier in the access authorization request is YYY (the operation identifier can usually be generated according to the initiation time, for example, can be generated according to 10:00:00 on October 1), the vision networking server C3 receives the access authorization request, processes the access authorization request, and stores the operation identifier YYY.

[0129] If the vision networking server C3 allows this authorization, the terminal information of the vision networking terminal C31 is returned to the first vision networking server, and the operation identifier YYY is stored corresponding to the terminal information. The terminal information includes: the effective time period is from 14:00:00 on October 1 to 16:00:00 on October 1, the effective time is 14:00:00 on October 1, the invalid time is 16:00:00 on October 1, the valid duration is 2 hours, the vision networking number CBDEU595 of the vision networking terminal C31, and the like. In this way, the first vision networking server can add the vision networking terminal C31 to the read-only operation list between 14:00:00 on October 1 and 16:00:00 on October 1, and pull the vision networking terminal C31 into the video conference X.

[0130] If the first video conference server cancels the video conference X at 13:00:00 on October 1st, and schedules the video conference X to 14:00:00 on October 2nd, that is, the terminal information of the target video conference terminal in the authorization request event corresponding to the operation identifier YYY needs to be modified, the first video conference server sends a request for changing the authorization access to the second video conference server, and the type is to modify the terminal information of the target video conference terminal. The content of the request is mainly that the access authorization request corresponding to the operation identifier YYY has been changed, and after the change, it is requested that the video conference server C3 grants the video conference server A0 the right to invite the video conference terminal C31 to participate in the video conference X from 14:00:00 on October 2nd to 16:00:00 on October 2nd. The second video conference server re-returns the changed terminal information of the video conference terminal C31 to the first video conference server according to the changed access authorization request. The terminal information includes: the valid time period is from 14:00:00 on October 2nd to 16:00:00 on October 2nd, the valid time is 14:00:00 on October 2nd, the invalid time is 16:00:00 on October 2nd, the valid time is 2 hours, the video conference number CBDEU595 of the video conference terminal C31, and the like.

[0131] If the first video conference server cancels the video conference X at 13:00:00 on October 1st, the first video conference server sends a request for changing the authorization access to the second video conference server, and the type is to cancel the authorization request event. The second video conference server determines the authorization request event corresponding to the operation identifier YYY according to the request for changing the authorization access, and then cancels the authorization request event. The canceled authorization request event does not exist from the beginning. After the second video conference server sends the first video conference server a successful cancellation of the authorization request event corresponding to the operation identifier YYY, the second video conference server deletes the video conference terminal C31 from the read-only operation list.

[0132] The method for changing the processed authorization request event provided in this embodiment makes the cross-domain access of the video conference terminal more flexible, and provides convenience for the first video conference server to cross-domain access the video conference terminal under the second video conference server.

[0133] In combination with the above embodiments, in an implementation, the terminal information of the target video conference terminal includes a valid time period of the first video conference server accessing the target video conference terminal. On this basis, receiving the terminal information of the target video conference terminal returned by the second video conference server after allowing the access authorization can specifically include the following steps:

[0134] Receiving the first terminal information of the target video conference terminal returned by the second video conference server after allowing the access authorization;

[0135] receive the second terminal information of the target vision net terminal returned by the third vision net server after the access authorization is allowed, the third vision net server being designated by the second vision net server and being a server that can be used to perform cross-domain authorization management on the vision net terminals directly connected to the second vision net server;

[0136] If there is a conflict vision net terminal, the or operation is performed on the effective time period in the first terminal information and the effective time period in the second terminal information, and the obtained time period is used as the effective time period in the terminal information of the conflict vision net terminal again, the effective time period in the first terminal information of the conflict vision net terminal being different from the effective time period in the second terminal information of the conflict vision net terminal.

[0137] In the embodiment, if the second vision net server is a subordinate vision net server of the third vision net server, the second vision net server can grant the third vision net server the right to perform cross-domain authorization management on the vision net terminals directly connected to the second vision net server when the third vision net server is in the default state.

[0138] After the second vision net server grants the third vision net server the right to perform cross-domain authorization management on the vision net terminals directly connected to the second vision net server, the second vision net server still has the right to perform cross-domain authorization management on the vision net terminals directly connected to the second vision net server, and the right will not disappear because of the assignment of the authorization.

[0139] For example, in the Figure 1 , the vision net server C3 can grant the vision net server C0 the right to perform cross-domain authorization management on the vision net terminals C31-C32 directly connected to the vision net server C3, at this time, the vision net server C0 can grant the vision net server A0 the right to access the vision net terminal C31, or can grant the vision net server A0 the right to access the vision net terminal C32.

[0140] Therefore, in actual implementation, after the first vision net server sends the access authorization request for the target vision net terminal to the second vision net server, if the second vision net server grants the third vision net server the right to perform cross-domain authorization management on the vision net terminals directly connected to the second vision net server, the first vision net server will receive the first terminal information of the target vision net terminal returned by the second vision net server after the access authorization is allowed, and the second terminal information of the target vision net terminal returned by the third vision net server after the access authorization is allowed.

[0141] For example, the WebRTC server C3 grants the WebRTC server C0 the right to perform cross-domain authorization management on the WebRTC terminals directly connected under the WebRTC server C3, and then the WebRTC server A0 sends an access authorization request to the WebRTC server C3 for the WebRTC terminal C31, and can receive the first terminal information of the WebRTC terminal C31 returned by the WebRTC server C3 and the second terminal information of the WebRTC terminal C31 returned by the WebRTC server C0.

[0142] According to the first terminal information and the second terminal information, if the effective time period in the first terminal information and the effective time period in the second terminal information are different for the same WebRTC terminal, the WebRTC terminal is a conflict WebRTC terminal. For example, the target WebRTC terminal is the WebRTC terminal C31, the effective time period in the first terminal information of the WebRTC terminal C31 is 10:00:00, October 1-12:00:00, October 1, and the effective time period in the second terminal information of the WebRTC terminal C31 is 10:00:00, October 1-13:00:00, October 1, so the WebRTC terminal C31 is a conflict WebRTC terminal, and then the or operation is performed on 10:00:00, October 1-12:00:00, October 1 and 10:00:00, October 1-13:00:00, October 1 to obtain the time period 10:00:00, October 1-13:00:00, October 1, and then 10:00:00, October 1-13:00:00, October 1 is re-set as the effective time period of the WebRTC terminal C31.

[0143] If there are multiple target WebRTC terminals and only one of them is a conflict WebRTC terminal, only the effective time period in the first terminal information and the effective time period in the second terminal information of the conflict WebRTC terminal need to be or operated to obtain a new effective time period.

[0144] In this embodiment, when the first WebRTC server detects the existence of a conflict WebRTC terminal, it can also send a prompt of the authorization conflict to the second WebRTC server and the third WebRTC server respectively to prompt the second WebRTC server to re-set the cross-domain authorization management right of the third WebRTC server.

[0145] In this embodiment, the second WebRTC server can grant the third WebRTC server the right to perform cross-domain authorization management on the WebRTC terminals directly connected under the second WebRTC server, so that when the second WebRTC server fails, the first WebRTC server can also access the WebRTC terminals directly connected under the second WebRTC server through the access right granted by the third WebRTC server, realize cross-domain access of the WebRTC terminals, and improve the convenience of cross-domain access of the WebRTC terminals.

[0146] In an implementation form, the method of the present application can further comprise:

[0147] receiving the access authorization request sent by the second visual internet server for the visual internet terminal under the first visual internet server;

[0148] determining a visual internet terminal to be accessed, and if the second visual internet server is allowed to access the visual internet terminal to be accessed, returning terminal information of the visual internet terminal to be accessed to the second visual internet server, so that the second visual internet server adds the visual internet terminal to be accessed to the read-only operation list according to the terminal information.

[0149] In the embodiment, the first visual internet server can also receive the access authorization request sent by other visual internet servers for the visual internet terminal under the first visual internet server and process it. After the first visual internet server authorizes, other visual internet servers can also perform read-only operation on the visual internet terminal under the first visual internet server, and the process is the same as the process principle of the second visual internet server processing the access authorization request described above. Therefore, it is not described here.
