Description
Technical Field
The present invention relates to the field of converged communication technologies, and in particular, to a method and a system for communication between a terminal and a video monitoring device.
Background
The existing converged communication scheme is shown in fig. 1, and includes a BOSS (Business Operation Support System), a DM Server (DM Server), an RCS AS (converged communication Server-application Server), a Telephony AS (Telephony application Server), an IMS Core (IP multimedia subsystem Core), and a terminal (UE); wherein, BOSS is connected with the terminal through SOAP/XML interface and is connected with Telephony AS through Ro interface/FTP; the DM server is connected with the terminal through an OMA DM interface; the DM server is connected with Telephony AS through a SOAP interface and is connected with RCS AS through a SOAP interface; the RCS AS is connected with the terminal through an XCAP interface/Ut interface; the Telephony AS is connected with the terminal through a Ut interface; the IMS Core is connected to the terminal through the Gm interface.
The system can accomplish user management, connection establishment and messaging, wherein the key system is the IMS Core.
As shown in fig. 2: the specific architecture of the IMS Core includes: SGSN (serving GPRS support node), GGSN (gateway GPRS support node), Internet (Internet) and PSTN (public switched telephone network), and IMS systems. In the figure, the solid line represents data transmission, and the dotted line represents signaling transmission.
Most of the existing video monitoring services have single functions, and only dynamic or static images set by a camera can be watched through a computer or a mobile phone. Conversation and message forwarding between receiving terminals cannot be realized. Part of the video system with the added multimedia message interaction is limited to the message transmission between the terminals supported by the system, the expandability is not strong, and the information can not be exchanged with the public network users. For the scheme combining the converged communication and the video monitoring, the service can only be one set of video monitoring service, and the architecture is not suitable for deploying converged communication services in a large scale and is also not suitable for deploying video monitoring services in a large scale.
The IMS system is used for realizing converged communication, and the defects of complex system and large data flow of terminal receiving and transmitting exist. The MQTT is utilized to realize convergence of communication services, so that networking complexity can be reduced, data volume can be reduced, communication efficiency can be improved, and terminal processing speed can be increased.
As shown in fig. 3, the MQTT (message queue telemetry transport) protocol only defines message interaction between publisher (publish client) and broker (subscribe server), and message interaction between broker (server) and subscribe client, and does not define a framework of multi-broker concatenation, i.e. message passing between multi-brokers.
