Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

In order to implement communication supporting three or more intercom devices, an embodiment of the present application provides a multiparty intercom system, which includes, referring to fig. 1, a plurality of cascaded platforms, where any one of the cascaded platforms may be connected to one or more intercom devices, and in some cases, some of the cascaded platforms may not be connected to an intercom device, and any intercom device connected to a first platform may invite one or more target intercom devices connected to one or more second platforms to establish an intercom group or join an established intercom group, where the second platform and the first platform may be in a cascade relationship or a cross-level relationship;

when a first platform receives an intercom invitation request sent by connected intercom equipment, the first platform generates an incoming intercom message according to target intercom equipment information invited in the intercom invitation request and second platform information connected with the target intercom equipment, wherein the incoming intercom message comprises first cascade path information from the first platform to the second platform; the first platform sends the incoming group talkback message to a next platform in the first cascade path, which is cascaded with the first platform, wherein the first platform is any one stage of platform in the multiparty talkback communication system, and the information of the first cascade path can be one or more;

and the third platform which receives the incoming group talkback message sends the incoming group talkback message to a next platform which is cascaded with the third platform in the first cascaded path information according to the first cascaded path information and/or sends the specified information in the incoming group talkback message to the connected target talkback equipment, wherein the third platform and the second platform can be the same platform or different platforms.

The platform in the embodiment of the application is a server for providing talkback services based on talkback software, and can be composed of one or more virtual machines and one or more physical machines. The talkback software is a system for controlling the talkback equipment and forwarding the audio stream, and provides an interface for a third-party platform to realize the control and stream fetching of the talkback equipment. A talkback group is a collection of talkback devices that participate in the same talkback session.

The first platform is any one of the multi-party intercom system, and the second platform can be one or more platforms. The first platform receives a talkback invitation request sent by a talkback device under its jurisdiction (hereinafter referred to as a first talkback device), where the talkback invitation request may include an identifier of a target talkback device to be invited, the target talkback device to be invited may be one or more, and the target talkback device may be the talkback device under the jurisdiction of the first platform or an talkback device under the jurisdiction of another platform except the first platform.

And if the target intercom device is the intercom device under the jurisdiction of the first platform, the first platform directly sends the group invitation information to the target intercom device under the jurisdiction of the first platform. For target talkback devices of which the platforms belong to other platforms except the first platform, the first platform can respectively generate an incoming talkback message for each target talkback device. When the second platform is a platform different from the first platform and the second platform is connected to the target intercom device, the first platform generates an incoming intercom message, the incoming intercom message includes first cascade path information from the first platform to the second platform, and the first cascade path information indicates a platform path from the first platform to the second platform.

Optionally, in a possible implementation, the first cascaded path information includes an identifier of each platform in the path from the first platform to the second platform. For example, as shown in fig. 2, when the first platform is the upper platform (denoted by 001) and the second platform is the lower platform 1 (denoted by 003), the first cascade path information is: 001002003. because the network domain limits that the network between the cross-level platforms can not be directly communicated, the network needs to be forwarded through the middle-level platform. The rectangle in the figure represents a platform, the cylinder represents intercom equipment managed by each stage of platform, the ID number on the platform is a platform identification and is used for distinguishing and butting other platforms, and the ID of the intercom equipment is the identification of the intercom equipment, namely the equipment ID of the intercom equipment registered to the platform and is used for distinguishing different intercom equipment in the same platform.

The first platform sends the incoming group talkback message to a next platform in the first cascade path and cascaded with the first platform. And the third platform sends the incoming group talkback message to the next platform cascaded with the third platform in the first cascade path information or sends the designated information in the incoming group talkback message to the target talkback equipment connected with the third platform according to the first cascade path information. The specified information in the group-entering talkback message may be group-entering invitation information, which is used for requesting the target talkback device to join the specified talkback group.

The third platform judges whether the third platform is a target platform of the incoming group talkback message according to the first cascade path information, for example, when the third platform is the last platform in the first cascade path information, the third platform judges that the third platform is the target platform of the incoming group talkback message. When the third platform judges that the third platform is the target platform of the incoming group talkback message (at the moment, the third platform is the second platform), the third platform sends the incoming group invitation information in the incoming group talkback message to the target talkback equipment connected with the third platform, wherein the incoming group talkback message is used for inviting the target talkback equipment to join the specified talkback group. The third platform sends the group invitation information to the target talkback equipment according to the target talkback equipment identification. For example, as shown in fig. 2, when the first platform is an upper platform, the second platform is a lower platform 1, and the target intercom device is intercom device D, the target intercom device identifier may be 159. When the third platform determines that the third platform is not the destination platform of the incoming group talkback message (at this time, the third platform is not the second platform), the third platform sends the incoming group talkback message to the next platform cascaded with the third platform in the first cascade path information.

In one possible embodiment, the incoming group talk message further includes: a path cursor, which is used by the third platform receiving the incoming group talkback message to send the incoming group talkback message to the next platform in the first cascade path information in cascade connection with the third platform according to the first cascade path information, and/or to send the designated information in the incoming group talkback message to the connected target talkback device, and which comprises:

after receiving the incoming group talkback message, the third platform judges whether the third platform is a target platform of the incoming group talkback message according to the path cursor and the first cascade path information of the incoming group talkback message; transmitting the incoming intercom message to a next platform in the first cascade path information, which is cascaded with the third platform, when the third platform is not a destination platform of the incoming intercom message; and when the third platform is the target platform of the incoming group talkback message, sending the specified information in the incoming group talkback message to the target talkback equipment connected with the third platform.

Specifically, after receiving the incoming group talkback message, the third platform may read a platform identifier corresponding to a path cursor of the incoming group talkback message in a first cascade platform path of the incoming group talkback message to obtain a current stage platform identifier; judging whether a platform identifier is included after a platform identifier of a current stage in the first cascade platform path; if the platform identification is not included after the platform identification of the current stage in the first cascade platform path, sending the incoming group talkback message to target talkback equipment connected with a third platform; if the platform identifier is included after the platform identifier of the current stage in the first cascade platform path, updating a path cursor in the talkback message (specifically, adding 1 to the path cursor value); and sending the incoming talkback message after the path cursor is updated according to the next platform identification after the platform identification of the current stage.

For example, in an incoming talkback message, the cascaded platform path is: 001002003, the path index value is 1, when the third platform is the current stage platform (ID002), the third platform starts to analyze the cascade platform path according to the position of the path index value 1 multiplied by 3 after receiving the talkback message, takes the three-digit character as 002 and compares with the number 002 of the third platform current stage, if the three-digit character is consistent with the number 002 of the platform, and when the platform number is in the back, the path cursor in the talkback message is added with 1 to process, and the talkback message is forwarded to the platform with the number 003 after analyzing the platform number 003 which needs to be forwarded. If not, the incoming talkback message may be discarded.

Optionally, after receiving the first intercom message, the first platform sends the first intercom message to a next platform in the cascade path information of the first intercom message, which is in cascade connection with the first platform, according to the cascade path information of the first intercom message, or sends the specific information in the first intercom message to a specific intercom device connected to the first platform; the designated information in the first talkback message is group invitation information or audio data, and the designated talkback device connected to the first platform is the talkback device in the talkback group corresponding to the first talkback message.

The first platform can be used as an inviting party and also can be used as a forwarding party or an invited party, the processing mode of the first platform for the first talkback message is the same as or similar to the processing mode of the third platform for the group talkback message, and the difference is that when the first talkback message carries audio data, the audio data sent by the first platform to the appointed talkback equipment connected with the first platform is audio data.

Optionally, the second platform sends a reply talkback message to the first platform, where the reply talkback message is for the incoming talkback message; and the first platform acquires the reply talkback message, and associates the target talkback device with the first talkback group when the reply talkback message indicates that the target talkback device connected with the second platform agrees to join the first talkback group.

The incoming group talkback message is used for inviting the target talkback device to join the first talkback group, for example, after the second platform acquires a response that the target talkback device connected to the second platform agrees to join the first talkback group, the second platform generates a reply talkback message, and the reply talkback message indicates that the target talkback device connected to the second platform agrees to join the first talkback group; and if the target talkback equipment connected with the second platform does not agree to join the first talkback group, the second platform generates a reply talkback message for indicating that the target talkback equipment connected with the second platform refuses to join the first talkback group. Of course, the second platform may also generate a reply talkback message indicating that the target talkback device is agreed to join the first talkback group when detecting that the target talkback device connected to the second platform is online.

The incoming group talkback message is used for inviting the target talkback device to join a first talkback group, and the first talkback group can be an established talkback group which comprises a plurality of talkback devices; or may be a newly established talkgroup for the first intercom device to invite the target intercom device. The reply talkback message includes cascade path information from the second platform to the first platform and a reply message indicating that the target talkback device agrees/refuses to join the first talkback group, after the first platform acquires the reply talkback message, when the reply talkback message indicates that the target talkback device connected to the second platform agrees to join the first talkback group, the first platform associates the target talkback device connected to the second platform with the first talkback group, for example, the target talkback device connected to the second platform is marked to join the first talkback group. The first platform may also send information to the first intercom device indicating that the target intercom device connected to the second platform joined the first intercom group. The sending process of the reply talkback message is the same as or similar to the sending process of the group talkback message, and the details are not repeated here.

Cascade talkback group number: a unique identifier that represents a particular intercom between intercom platforms. Path cursor: and identifying the cascade path information position of the current message receiver, and verifying, processing and forwarding the current message by the platform for receiving the cascade message. Cascade path information: representing all platform numbers traversed by the current message from sender to recipient. Talkback group number: the number of the talkback group can be a number between 1 and 999. Platform numbering: namely, platform identification, which is used for identifying the platform and can be a three-digit character string between 001 and 999, and is needed to be used during the cascade talkback.

As shown in fig. 2, a user uses a device a of an upper platform to initiate a call to a device B of the current platform, a device D of a lower platform 1, a device E of the lower platform 1, and a device F of the lower platform 2, and mixing rules of each platform are as shown in fig. 4. In fig. 4, a part of the intercom platform may send or receive more than one audio stream, for example, the upper platform may receive an audio stream from the device B of the software of the current level (i.e., B stream), a mixed stream from the D device and the E device of the lower platform 1 (i.e., DE stream, obtained by mixing audio data of the D device and the E device by the lower software 1), and an audio stream from the F device of the lower platform 2 (i.e., F stream). Judging according to the cascade path information of each talkback message to be mixed, wherein a superior platform needs to send an A stream (an audio stream generated by the talkback message of the device A in superior software), a DE stream and an F stream to the current platform, so that the A stream, the DE stream and the F stream are mixed to obtain the mixed talkback message, and the method comprises the following steps: an ADEF stream; the superior platform needs to send a stream, a stream B and a stream F to the inferior platform 1, so the stream a, the stream B and the stream F are mixed to obtain the mixed talkback message, which includes: an ABF stream; the superior software platform sends the stream a, the stream B and the stream DE to the inferior platform 2, so that the stream a, the stream B and the stream DE are mixed to obtain the mixed talkback message, which comprises: the ABDE flow. Wherein, the cascade path information of the ADEF flow is: 001002, the cascade path information of the ABF flow is: 001002003, the cascade path information of the ABDE flow is: 001002004.

in one possible embodiment, the talk-back message includes: the system comprises cascade path information and a target intercom device identifier, wherein the cascade path information comprises identifiers of all platforms on a propagation path from an initiating platform to a receiving platform, and the target intercom device identifier is an identifier of intercom devices to be communicated. Optionally, the talkback message further includes: the cascade talkback group number comprises cascade path information and a talkback group number, and the talkback group number uniquely identifies the talkback group. The intercom message may also include a path cursor.

The talkback message is a general term of messages interacted among platforms, and includes an incoming talkback message, an agreement to an incoming talkback message, a first talkback message, a second talkback message, a third talkback message and the like. The cascaded path information characterizes all platforms that the intercom message passes through from the sender platform to the recipient platform. Cascade talkback group number: a unique identifier that represents a particular intercom between intercom platforms. The cascade talkback group number comprises cascade path information and a talkback group number, and the talkback group number is used for distinguishing different talkback groups.

In order to realize the cascade connection of a plurality of intercom devices, signaling and audio stream forwarding between platforms are required. Because different cascade messages need to be checked, forwarded or processed, for each talkback message, a path cursor and a cascade path information field need to be added to the talkback message to identify a source party and a receiving party of the talkback message and a transfer party for forwarding the message. The talkback message may further include a cascade talkback group number, and the cascade talkback group number includes the talkback group number. As the initiator platform needs the talkback group number to uniquely identify the talkback group, the cascaded platform (the platform except the initiator platform is called the cascaded platform) also needs to identify the talkback group of the cascaded talkback through the cascaded talkback group number. Since cascade talkback involves multiple platforms, each platform contains multiple talkback devices, so a global talkback group number capable of spanning multiple platforms is needed, each platform in cascade can clearly know which talkback group the talkback device managed by itself belongs to, thereby facilitating inviting new devices to join in a correct talkback group or correctly mixing and forwarding audio streams. The platform of the cascade talkback initiator generates the cascade group number used by the platform of the called party according to the talkback group number naming rule and transmits the cascade group number to other talkback software through a signaling protocol.

Specifically, as shown in fig. 2, the user uses the a device of the upper platform to initiate a call to the B device of the current platform, the D device of the lower platform 1, and the F device of the lower platform 2.

And discarding the talkback message when the two messages are inconsistent. The following processing flows of the cascade path information and the path cursor are consistent with each other, and are not described in detail.

Wherein, in the message sent by the superior platform (ID001) to the current platform (ID002), the cascade path information is: 001002 cascade talkback group number 001002666 and path cursor 1. In the message sent by the upper platform (ID001) to the lower platform 2(ID004), the cascade path information is: 001002004, Cascade talkback group number 001002004666, and path cursor 1. In the message returned by the current-stage platform (ID002) to the previous-stage platform (ID001), the cascade path information is: 002001, Cascade talkback group number 001002666, and path cursor 1.
