Embodiment 1

[0061] figure 1 For the flow chart of the voice intercom method based on the GB28181 protocol of the present invention, reference will be made below figure 1 , to describe in detail the implementation of the voice intercom method based on the GB28181 protocol of the present invention.

[0062] First, in step 1, the client initiates a voice intercom request to the SIP server. In the embodiment of the present invention, the voice intercom request includes: the IP of the SIP service, port information and the ID information of the designated individual equipment.

[0063] In step 2, the SIP server sends a voice broadcast request to the individual mobile phone device. In the embodiment of the present invention, the voice broadcast request includes: SIP service IP, port information, specified individual device ID information, and broadcast key field.

[0064] In step 3, the mobile phone individual device returns 200 OK to the SIP server.

[0065] In step 4, the mobile phone indi...

Embodiment 2

[0082] figure 2 For mobile phone individual equipment work flow diagram according to the present invention, below will refer to figure 2 , and describe in detail the workflow of the mobile phone individual device of the present invention.

[0083] In step 1, the JNI interface initializes the underlying resources by calling Java_com_autulin_gb28181library_JNIBridge_initMuxer, and instantiates the class GB28181Muxer.

[0084] In step 2, call the interface function GB28181Muxer::initMuxer to initialize ffmpeg and create a decoding thread GB28181Muxer::startEncode.

[0085] In step 3, instantiate GB28181_sender.

[0086] In step 4, initialize GB28181_sender::initSender to initialize network resources, connect to the interface scoket of the SIP server according to the IP and port of the SIP server, wait in a loop after the connection is successful, until there is data to send to the SIP server.

[0087] In step 5, instantiate GB28181_Receive.

[0088] In step 6, initialize GB...

Embodiment 3

[0103] image 3 It is a schematic diagram of the realization of the voice intercom system architecture based on the GB28181 protocol according to the present invention, such as image 3 As shown, the voice intercom system based on the GB28181 protocol of the present invention includes a client 10, a SIP server 20, and a mobile phone individual device 30, wherein,

[0104] The client 10 initiates a voice intercom request to the SIP server 20, and conducts a voice intercom call with the corresponding mobile phone individual device 30 through the SIP server 20.

[0105] In the embodiment of the present invention, the client 10 initiates a voice intercom request to the SIP server 20; receives the message sent by the SIP server 20 carrying the sdp and returns a successful reception message; receives the 200 OK message sent by the SIP server 20 and carries the ACK message , send the RTP voice message to the SIP server 20; receive the RTP voice packet from the mobile phone individua...

Abstract

A method for realizing voice talkback based on a GB28181 protocol comprises the following steps: 1) an SIP server receives a voice talkback request sent by a client and sends a voice broadcast request to a mobile phone individual soldier device; 2) the SIP server receives an INVITE message sent by the mobile phone individual soldier equipment, and sends a message carrying an sdp to the client; 3) the SIP server sends a port receiving success message containing the voice stream to the mobile phone individual soldier equipment, and establishes a voice talkback channel for the client and the mobile phone individual soldier equipment; and 4) the mobile phone individual soldier equipment transmits an RTP voice message to the client through the SIP server so as to carry out voice talkback conversation. The invention further provides a system for realizing the voice intercom based on the GB28181 protocol, the requirements of mobile law enforcement and emergency command and dispatch of a smart city are met, the mobile phone individual soldier equipment can be installed on a personal mobile phone, and the system has the advantages of being convenient to carry and flexible to use.
