Abstract

The embodiment of the invention provides a transmission link management method and system, and the method comprises the steps: receiving a data request based on an Internet protocol from a service terminal through a transcoding server, enabling the data request to be used for requesting the data of a target camera, carrying out the transcoding through the transcoding server, obtaining a request message in a binary format, sending the request message to a scheduling center server, generating a request message index and abstract description information of the request message by the scheduling center server, converting the binary request message into an SIP request message in an SIP protocol format, and sending the SIP request message to enable the target camera to respond according to the SIP request message; and when the dispatching center server receives an SIP response message returned by the target camera, the SIP response message being converted into a binary response message, and how to return the response message being determined according to the request message index and the abstract description information. Therefore, the intercommunication between the Internet protocol and the SIP protocol is realized.

Description

technical field [0001] This application relates to the technical field of smart cities, and in particular to a transmission link management method and system. Background technique [0002] GB / T28181 is generally used in the security monitoring industry. For example, in the existing security monitoring system, the devices connected to the security monitoring system use the SIP protocol (Session Initiation Protocol) in GB / T28181 to communicate with each other. communication. The equipment in the security monitoring system includes upper and lower cascading equipment and various cameras (such as high-definition network cameras and network video recorders (Network Video Recorde, NVR) in the monitoring industry, etc.), that is, the upper and lower cascading equipment in the existing security monitoring system The communication between the upper and lower cascaded devices and the camera, etc. all use the SIP protocol for SIP communication. Therefore, a special SIP client needs t...
