The method, the system, the equipment and the storage medium for the audio and video call of the local area network can be applied to the field of the audio and video call. Fig. 1 is a first flowchart of a local area network audio/video call method according to an embodiment of the present application, and as shown in fig. 1, the method includes the following steps:
step S102, the SIP server receives a call request of a first intelligent terminal;
step S104, the SIP server sends a call control instruction corresponding to the call request to the control server;
step S106, the control server acquires second attribute information of a second intelligent terminal corresponding to the call control instruction from the equipment center server;
step S108, based on the second attribute information, the SIP server sends a call request to the second intelligent terminal;
step S110, based on the call request, the SIP server controls the first intelligent terminal and the second intelligent terminal to establish a call channel and a real-time transmission protocol channel;
the equipment center server manages the first intelligent terminal and the second intelligent terminal.
Wherein, the SIP server is a Session Initiation Protocol (SIP) server; the Real-time Transport Protocol (RTP) channel is a Real-time Transport Protocol (RTP) channel.
In some embodiments, the equipment center server may uniformly manage, configure, and monitor several intelligent terminals. The equipment center server stores the attribute information of the intelligent terminals, and can provide the attribute information of the intelligent terminals for the control server. If the control server needs to obtain the attribute information of one intelligent terminal from the equipment center server, the equipment center server may retrieve the attribute information of several intelligent terminals stored in the equipment center server, and then send the retrieved attribute information corresponding to the intelligent terminal to the control server. The attribute information may include account information and address information.
In some embodiments, the SIP server may receive a call request of one first intelligent terminal or may receive call requests of several first intelligent terminals at the same time. In the same time node, under the condition that the SIP server receives call requests of a plurality of first intelligent terminals, the SIP server simultaneously sends call control instructions corresponding to the call requests to a control server; then the control server can obtain second attribute information of a second intelligent terminal corresponding to the call control instruction from the equipment center server according to the call control instructions; based on the second attribute information, the SIP server respectively sends a plurality of call requests to the second intelligent terminal; based on the plurality of call requests, the SIP server controls the plurality of first intelligent terminals and the plurality of second intelligent terminals to simultaneously construct call channels and real-time transmission protocol channels.
The call control instruction is used for enabling the control server to perform call control on the call of the first intelligent terminal, and specifically includes that the control server performs call authentication, authentication verification, call establishment, call holding, call forwarding and call clearing on a call request of the first intelligent terminal.
In some embodiments, in the case where the first intelligent terminal sends a call request to the SIP server, the SIP server may acquire the first attribute information of the first intelligent terminal. Under the condition that the SIP server controls a call channel and a real-time transmission protocol channel to be constructed between the first intelligent terminal and the second intelligent terminal, the first attribute information of the first intelligent terminal can be displayed on the second intelligent terminal.
Under the condition that a calling channel and a real-time transmission protocol channel are established between the first intelligent terminal and the second intelligent terminal, the first intelligent terminal and the second intelligent terminal can transmit audio streams and video streams through the real-time transmission protocol channel and support a point-to-point transmission scheme, so that audio and video conversation between the first intelligent terminal and the second intelligent terminal is realized.
Under the condition of constructing a real-time transmission protocol channel, the first intelligent terminal and the second intelligent terminal can not only transmit audio streams and video streams, but also support digital coding transmission, can perform protocol coding and process special events and services.
Through the steps S102 to S110, the problem that the call limitation and the deployment limitation are large when the equipment in the community carries out audio and video calls based on the public network is solved, the audio and video calls of the intelligent equipment in the community can be simply and conveniently carried out through the local area network, and the call limitation and the deployment limitation are low when the audio and video calls are carried out between the intelligent equipment.
Fig. 2 is a second flowchart of the local area network audio/video call method according to the embodiment of the present application, and as shown in fig. 2, in the case that the number of the control servers is n, and n is a positive integer greater than 1, the method further includes the following steps:
step S202, the SIP server receives a call request of the first intelligent terminal;
step S204, the SIP server sends a call control instruction corresponding to the call request to the first control server;
step S206, under the condition that the first control server does not respond, the SIP server sends a call control instruction corresponding to the call request to the second control server;
step S208, the second control server acquires second attribute information of the second intelligent terminal corresponding to the call control instruction from the equipment center server;
step S210, based on the second attribute information, the SIP server sends a call request to the second intelligent terminal;
step S212, based on the call request, the SIP server controls the first intelligent terminal and the second intelligent terminal to establish a call channel and a real-time transport protocol channel.
When the SIP server cannot determine from which control server the second attribute information of the second intelligent terminal can be directly obtained, the SIP server may sequentially access the control servers connected to the SIP server, for example, the SIP server may first access the first control server, and when the first control server does not respond, the SIP server may sequentially access the second control server, the third control server, … …, and the nth control server until the SIP server sends a call control instruction to the control servers capable of obtaining all the second attribute information of the second intelligent terminal, and the control servers obtain the second attribute information of the second intelligent terminal.
The method comprises the steps that when a first intelligent terminal sends a call request to an SIP server, the call request can include part of second attribute information of a second intelligent terminal, and the SIP server selects a proper control server according to the part of second attribute information to acquire all second attribute information of the second intelligent terminal, so that a call channel and a real-time transmission protocol channel can be constructed between the first intelligent terminal and the second intelligent terminal. If the SIP server knows that the address information of the first control server and the address information of the second intelligent terminal are both in the same address field through part of the second attribute information of the second intelligent terminal, the SIP server sends a call control instruction corresponding to the call request to the first control server.
In some embodiments, in a case where the SIP server cannot select an appropriate control server to obtain all the second attribute information of the second intelligent terminal corresponding to the call control instruction according to the part of the second attribute information of the second intelligent terminal, if the SIP server can determine that one of the part of the control servers can obtain all the second attribute information of the second intelligent terminal according to the part of the second attribute information of the second intelligent terminal, the SIP server may sequentially send the call control request to the part of the control servers.
For example, in the case of 10 control servers, after the first intelligent terminal sends a call request to the SIP server, if the SIP server can determine that one of the 3 rd to 8 th control servers can obtain all the second attribute information of the second intelligent terminal according to part of the second attribute information of the second intelligent terminal, the SIP server may directly send a call control command corresponding to the call request to the 3 rd control server, and in the case that the 3 rd control server cannot obtain all the second attribute information of the second intelligent terminal, the SIP server sequentially sends the call control command corresponding to the call request to the 4 th control server, the 5 th control server, … …, and the 8 th control server until the SIP server sends the call control command to the control servers that can obtain all the second attribute information of the second intelligent terminal, and the control server acquires second attribute information of the second intelligent terminal.
In some embodiments, in a case where the SIP server cannot determine from which control server the second attribute information of the second intelligent terminal can be directly obtained, the SIP server identifies the first attribute information of the first intelligent terminal, and if the SIP server retrieves that a control server can obtain the first attribute information of the first intelligent terminal, the SIP server sends a call control instruction corresponding to the call request to the control server to obtain the second attribute information of the second intelligent terminal, and if the first control server does not respond, sends a call control instruction corresponding to the call request to a control server adjacent to the control server.
In some embodiments, in a case that the SIP server cannot determine from which control server the second attribute information of the second intelligent terminal can be directly obtained, the SIP server obtains a call record of the first intelligent terminal in a recent period, and if a connection record with the second intelligent terminal is included in the call record, the SIP server sends a call control instruction to the control server that can previously obtain the second attribute information of the second intelligent terminal, so as to establish a call channel and a real-time transport protocol channel between the first intelligent terminal and the second intelligent terminal.
Through the steps S202 to S212, distributed deployment of the control servers is realized, the problem of overlarge access pressure caused by the fact that the SIP server only accesses a single control server is solved, and the SIP server can quickly access the control servers.
Fig. 3 is a flow chart of a local area network audio/video call method according to an embodiment of the present application, and as shown in fig. 3, in a case that the number of the device center servers is m, and m is a positive integer greater than 1, the method further includes:
step S302, the SIP server receives a call request of a first intelligent terminal;
step S304, the SIP server sends a call control instruction corresponding to the call request to the control server;
step S306, the control server sends second attribute information of the second intelligent terminal corresponding to the call request from the first equipment center server;
step S308, under the condition that the first equipment center server does not respond, the control server acquires second attribute information of the second intelligent terminal corresponding to the control instruction from the second equipment center server;
step S310, based on the second attribute information, the SIP server sends a call request to the second intelligent terminal;
step S312, based on the call request, the SIP server controls the first intelligent terminal and the second intelligent terminal to establish a call channel and a real-time transport protocol channel.
Each control server can be connected with at least one equipment center server, and the control server can acquire the required second attribute information of the second intelligent terminal from the equipment center server connected with the control server. When the control server cannot determine which equipment center server needs to directly acquire the second attribute information of the second intelligent terminal, the control server may sequentially access the equipment center servers connected to the control server, for example, the control server may first access the first equipment center server, and when the first equipment center server does not respond, the control server may sequentially access the second equipment center server, the third equipment center server, … …, and the mth equipment center server until the required second attribute information of the second intelligent terminal is acquired.
In some embodiments, in a case where the control server cannot determine from which equipment center server the second attribute information of the second intelligent terminal can be directly obtained, the control server may obtain the second attribute information of the second intelligent terminal by the first equipment center server storing the first attribute information of the first intelligent terminal according to the received call control instruction corresponding to the call request. In the case that the first device center server does not respond, the control server may access the device center server adjacent to the first device center server until the second attribute information of the second smart device is acquired.
In some embodiments, in a case where a call control instruction corresponding to the call request is received, the control server may obtain all call records of the first intelligent terminal in a recent period according to the call control instruction, and sequentially initiate access to a second equipment center server where a second intelligent terminal connected to the first intelligent terminal is located, so as to obtain second attribute information of the second intelligent terminal.
Through the steps S302 to S312, distributed deployment of the device center servers is realized, so that the control server can acquire the second attribute information of the second intelligent terminal from the plurality of device center servers, thereby reducing the access pressure of the device center servers.
Fig. 4 is a fourth flowchart of the local area network audio/video call method in the embodiment of the present application, and as shown in fig. 4, after the SIP server sends a call control instruction corresponding to the call request to the control server, the method further includes;

step S406, based on the call request, the SIP server controls the first intelligent terminal and the second intelligent terminal to establish a call channel and a real-time transmission protocol channel;
the first equipment center server manages the first intelligent terminal, and the second equipment center server manages the second intelligent terminal.
The first equipment center server and the second equipment center server may be deployed at the same location or at different locations. For example, a first device center server may be deployed in a first community, and a second device center server may be deployed in a second community, so that different communities can perform audio and video calls. In the case of a large community, the first equipment center server and the second equipment center server may be deployed at different locations in the community.
Through steps S402 to S406, the control server obtains the attribute information of the second intelligent terminal from the second device center server, and the second device center server and the first device center server may be deployed at different locations, so as to achieve the effect of performing one-to-one call across communities.
Fig. 5 is a fifth flowchart of the local area network audio/video call method in the embodiment of the present application, and as shown in fig. 5, after the SIP server sends a call control instruction corresponding to the call request to the control server, the method further includes:
step S502, the control server obtains second attribute information of a second intelligent terminal and third attribute information of a third intelligent terminal corresponding to the call control instruction from the first equipment center server;
step S504, based on the second attribute information and the third attribute information, the SIP server sends call requests to the second intelligent terminal and the third intelligent terminal respectively;
step S506, based on the call request, the SIP server controls the first intelligent terminal, the second intelligent terminal, and the third intelligent terminal to establish a call channel and a real-time transport protocol channel.
The first equipment center server manages the first intelligent terminal, the second intelligent terminal and the third intelligent terminal.
The SIP server can control the first intelligent terminal and the second intelligent terminal to establish a calling channel and a real-time transmission protocol channel, the first intelligent terminal and the third intelligent terminal to establish a calling channel and a real-time transmission protocol channel, and the second intelligent terminal and the third intelligent terminal to establish a calling channel and a real-time transmission protocol channel, so that the first intelligent terminal, the second intelligent terminal and the third intelligent terminal can carry out audio and video conversation with each other.
The SIP server is not limited to establishing a call channel and a real-time transport protocol channel among the first intelligent terminal, the second intelligent terminal and the third intelligent terminal, and the SIP server can control at least three intelligent terminals to establish a call channel and a real-time transport protocol, for example, the call channel and the real-time transport protocol channel can be established among four intelligent terminals.
In some embodiments, the SIP server may limit the number of the intelligent terminals connected to the first intelligent terminal at the same time node, for example, when the SIP server limits the number of the intelligent terminals connected to the first intelligent terminal at the same time node to be 50, if the first intelligent terminal initiates a call request to 51 intelligent terminals at the same time point, the SIP server prevents the first intelligent terminal from initiating a call to the 51 st intelligent terminal, so that the first intelligent terminal can only connect 50 second intelligent terminals, thereby solving the problem that when the first intelligent terminal connects too many second intelligent terminals, the first intelligent terminal occupies too many local area network resources, and the other intelligent terminals cannot smoothly perform audio/video calls or cannot perform audio/video calls.
Through the steps S502 to S506, the audio and video call can be carried out among a plurality of intelligent devices managed by the same equipment center server through the SIP server.
