Technical field
The present invention relates to the video management network, relate in particular to, for example based on the method and the corresponding device thereof of control transmission Media Stream between subscriber equipment and video service device in the video management network of telecommunication network at the video management network.
Background technology
At present, in many instances all need be based on the video monitoring system of telecommunication network (for example the Internet), for example vehicle supervision department need install video monitoring system throughout the country, and management system is set at the traffic control center of various places, so that the management system of various places can be carried out video monitoring to the traffic conditions in the one's respective area.Video monitoring by various places (zone), can constitute tree-shaped (when each traffic control center the has the level region timesharing) structure of a solid or the management system of network structure (when each traffic control center is not distinguished rank), by such management system, theoretically, through suitable request and authentication, can check in authority that any traffic control center is responsible for the captured image of any camera head of maintenance thereby can be connected to this video monitoring control network by any interface.
Similarly, similar video monitoring system can be applied in other field, and for example the video monitoring system based on local area network (LAN) need be installed in the residential quarter, so that the security situation of supervision sub-district.For such system based on local area network (LAN), any one service provider can adopt the video monitoring system of design voluntarily to realize user's demand, but for a large-scale system for managing video based on telecommunication network, then because the huge fellowship that often needs in a plurality of suppliers, the service of quantities is finished system's construction, for example need the supplier that proposes the contractor of global design scheme and supply various device etc. at least.At this moment, on the one hand owing to do not form unified standard in field of video monitoring systems, each service provider design separately often can not be compatible, and is difficult when causing building large-scale video management network.Also there are various problems the solution of existing on the other hand video management network in itself.
For example, in an existing solution, the video management network comprises media gateway, control SGW, storage agent, information server and database etc., and a plurality of subscriber equipment is connected with this video network, and video server also is connected with this video network.Wherein, for example media gateway is used for the request of proxy user equipment incoming video stream, and is connected to the front end video capture device, carries out video flowing control from video server to subscriber equipment distribution of video stream and in the video management network internal; The control SGW is used for receiving control command from subscriber equipment, and is connected to video server and finishes these control commands; Storage agent receives order, is recorded in this memory as user agent's incoming memory and with specific video stream from service server; Information server is the central information server of this video management network, it receives the query requests at network configuration data and subscriber equipment related data from above-mentioned service server, media gateway, control SGW, also receives report information from other assemblies.
In above-mentioned existing scheme, use different agreement between each assembly of video management network, for example, use proprietary protocol based on UDP to make subscriber equipment and storage agent incoming stream media resource; Use makes subscriber equipment can insert the video management network based on the proprietary protocol of TCP and obtains video flowing, and uses same agreement control of video flow transmission; Use snmp protocol as the report information agreement, make that other assemblies come to the information server report information etc.
But there are a lot of problems in above-mentioned solution, and amount is used proprietary protocol on the one hand, causes being difficult to interconnect, and is difficult to the management of media session on the other hand.For example, this scheme uses same controlling mechanism to make subscriber equipment obtain video flowing, and uses this mechanism control of video flow transmission (for example control transmission speed), causes and can't distinguish management of media transmission and medium control; Again for example, the media delivery between subscriber equipment and video server lacks feedback message, causes video server can't determine whether the Media Stream that is transmitted is successfully received by subscriber equipment; For another example, media delivery can't be managed media delivery between the two based on point-to-point connection the between subscriber equipment and video server (as camera head), and this does not meet the needs to the video network management yet.
Therefore, such solution is the video monitoring system that can't solve based on telecommunication network, when especially being a large-scale complication system in this system.
