[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Figure 1 1 is a flow chart of a telephone conference method based on a VOIP phone according to an embodiment of the present invention. The execution subject of the method can be a VOIP main process, such as Figure 1 As shown, the telephone conference method includes the following steps:

[0025] S1, after receiving the command to establish a conference, initialize the conference data structure, which includes global data and a list of downstream device data, and write the local node as the conference chairperson into the first node of the downstream device list.

[0026] Specifically, the user starts to prepare for a conference call. After the VOIP main process receives the command to establish a conference, it establishes an empty conference data structure, which includes global data and a list of downstream devices. The list of downstream devices is used to record the sub-node information of the conference, and the local node is written as the conference chairperson to the first node in the list of downstream devices.

[0027] S2, set the conference ID and write it into the global data, so that the conference ID corresponds to the chairman node.

[0028] In one implementation of the present invention, setting the conference ID specifically includes: combining the time node of the current conference initiation and the MAC address of the conference chairperson into a conference ID.

[0029] Specifically, the conference ID can be composed of the time node of the current conference initiation and the MAC address of the conference chairperson, which is used to identify the unique mark of the conference. For example, 20240322134100faea01 means the conference No. 01 initiated by device 00:fa:ea at 13:41 on March 22, 24. It can basically avoid the situation of duplicate IDs, and manually or automatically generate the access key of the conference. At this point, the conference is established locally, and the conference ID is matched with the chairperson node in the local device list.

[0030] S3, initiates a meeting invitation message to the child node. After receiving the response message from the child node, writes the RTP media address and port information of the child node corresponding to the response message into the list of downstream devices. The invitation message carries the conference ID and the media encoding information used by the conference chairperson, and the response message carries the RTP media address and port information of the child node.

[0031] S4, receiving the request to join the meeting information sent by the child node, authenticating the request to join the meeting information, and after successful authentication, writing the RTP media address and port information of the child node corresponding to the request to join the meeting information into the list of downstream devices.

[0032] Furthermore, in one embodiment of the present invention, the request to join a conference carries the conference ID, the RTP media address and port information of the child node, and password information.

[0033] Specifically, after obtaining the invitation member account, the local (conference chairperson) sends a joining invitation message to this member account, and carries the above-established conference ID and the media encoding information used by the conference chairperson. The other end starts ringing or other prompts to request to join this conference. If the other end accepts the invitation, it will give a 200OK response to the I joining invitation message, which carries the address and port information of the RTP media of the node account. After receiving this 200OK response, the conference chairperson writes the corresponding child node information into the list of hanging devices.

[0034] If the other end knows the conference ID, it can directly initiate a request to join the conference, carrying the corresponding conference ID, RTP media address and port information, and the correct password information to the conference chair. The chair receives it and performs authentication. After successful authentication, the corresponding child node information is written into the list of downstream devices, and its status is equal to that of the invited node.

[0035] S5, judging whether the subnode in the downstream device list belongs to the subnode permission list according to the subnode RTP media address and port information, discarding the subnode that does not belong to the subnode permission list from the downstream device list, and writing the RTP data stream of the subnode that belongs to the subnode permission list into the global data.

[0036] Specifically, the RTP media address and port information of the subnodes in the downlink device list is used to determine whether the subnodes in the downlink device list belong to the subnodes in the subnode permission list. If not, the subnode is discarded from the downlink device list, and the RTP data stream of the subnodes in the node permission list is written into the global data. Thus, the node identity and the media stream are separated, and only the media stream of the legal address of the conference is received according to the node identity, without the need to establish a conference bridge function, which greatly saves system resources.

[0037] S6, mixing the RTP data stream and playing it.

[0038] Specifically, after the legal RTP data stream is admitted, unified mixing is performed, and the bottom layer continues to hand it over to the hardware, sound or image device for playback based on the received audio stream.

[0039] In a specific embodiment of the present invention, the RTP data stream is mixed and played, which specifically includes: decoding the RTP data streams of the conference chairperson and all child nodes into a unified analog signal and writing it into a downstream unified mixing thread to mix the sound signal; the conference chairperson and all child nodes reversely clear the local analog signal and the mixed sound signal and then play it.

[0040] Specifically, Figure 2 As shown, in order to save resources, a unified analog signal superposition mixing method is used for playback. For the conference chairman, the status is the same as that of each sub-node. The MIC signal of the RTP data stream of the conference chairman is directly encoded as an analog signal, and then decoded into the "downstream unified mixing" thread, so as to achieve a unified analog signal for the entire conference. However, the local playback of the conference chairman, "speak", does not need to receive the local sound. Therefore, after the local analog signal and the downstream unified mixing are reversely cleared, the analog sound of all sub-nodes can be obtained, excluding the local sound.

[0041] For all child nodes, similar simulation processing is performed. After decoding, the RTP data stream of any child node is uniformly entered into the "downstream unified mixing" thread for mixing and superposition. When the sound signal corresponding to the child node and the sound signal of the downstream unified mixing are reversely filtered and transmitted to the corresponding child node at the remote end, the remote end can hear the signals of all other nodes except itself.

[0042] In summary, according to the VOIP phone-based conference call method of the embodiment of the present invention, the node identity and media stream are separated, and the media stream belonging to the legal address of the conference is managed, decoded and played according to the node identity. There is no need to establish a conference bridge function, and a relatively small system resource can be used for large-scale conference calls or broadcasting services. In addition, there is no need for a separate mixing server device, which greatly saves conference costs.

[0043] Corresponding to the above-mentioned telephone conference method based on VOIP phone, the present invention also proposes a telephone conference device based on VOIP phone. Since the device embodiment of the present invention corresponds to the above-mentioned method embodiment, the details not disclosed in the device embodiment can be referred to the above-mentioned method embodiment, and will not be repeated in the present invention.

[0046] According to an embodiment of the present invention, the setting module 2 is specifically used to: combine the time node of the current conference initiation and the MAC address of the conference chairperson into a conference ID.

[0047] According to an embodiment of the present invention, the request to join a conference carries the conference ID, the RTP media address and port information of the child node, and password information.

The RTP media address and port information of the node are written into the downstream device list, and then the sub-node in the downstream device list is judged whether it belongs to the sub-node permission list according to the sub-node RTP media address and port information. The sub-nodes that do not belong to the sub-node permission list are discarded from the downstream device list, and the RTP data stream of the sub-node that belongs to the sub-node permission list is written into the global data.
