Description
Technical field
The present invention relates to a kind of method and system of configuring distributed proxy server information, particularly a kind of by Xin Lingdaili (Signalling Proxy, be called for short SP) the unified configuring distributed proxy server information of equipment, make SP configuration information and Media proxy (Media Proxy, be called for short MP) method that is consistent of configuration information, and a kind of by the unified configuring distributed proxy server information of SP equipment, the system that SP configuration information and MP configuration information are consistent belongs to communication technical field.
Background technology
Increasingly mature along with the IP technology, with soft switch and IP packet-switch technology is next generation network (the Next Generation Network of core, be called for short NGN) technology, because its wide application prospect and, become one of focus that industry pays close attention to most to the support of people's variation, individual business demand.As the visual plant among the NGN, (be called for short: PROXY) the typical networking model in the NGN network as shown in Figure 1 for acting server.
PROXY is the soft switchcall server of terminal 1 as the Xin Lingdaili and the Media proxy of terminal 1.The SP flow process of PROXY is: the user's registration and the call information of terminal 1 all send to PROXY, and PROXY is through being transmitted to the application server or the terminal 2 of core net again after the signaling process; When application server or terminal 2 calling terminals 1, call request at first sends to PROXY, and PROXY is transmitted to terminal 1 again through after the signaling process.In this process, PROXY need support SIP (Session Initiation Protocol, be called for short SIP), the MGCP of audio frequency and video agreement, ietf standard (Media GatewayContro1ler Protoco1 H.323, abbreviation MGCP), H.248 the MGCP of ITU-T standard waits one or more agent functionalitys in the agreement, and because PROXY has participated in whole flow process, so PROXY can obtain details such as corresponding user's registration, calling.The flow process of the MP of PROXY is: when PROXY agency's terminal 1 when terminal 2 or application server send Media Stream, at first need processing and forwarding through PROXY, therefore, the destination address that terminal 1 sends Media Stream is the PROXY address; When terminal 2 or server when terminal 1 sends Media Stream because same processing and forwarding through PROXY, therefore sending the address of pointing to is the address of PROXY.The schematic diagram of PROXY proxy signaling stream and Media Stream as shown in Figure 2, solid line is a Media Stream, dotted line is a signaling flow.
As can be seen: the signaling flow of terminal 1 and Media Stream are all handled and transfer by PROXY.Because the number of signaling message is generally less, calling is greatly about about 10 signaling messages, and Media Stream just may reach 30～50 messages one second, therefore, has caused the asymmetry of signaling traffic and medium flow.Because PROXY must guarantee that signaling message and media message can both in time obtain handling, under the situation that the media message flow is big in that the signaling message flow is little, the processing of media message has occupied the most processing resource of PROXY, therefore the conversation number causes centralized PROXY capacity to be difficult to improve when having limited PROXY and can handle.
Therefore, at present big capacity PROXY adopts distributed treatment, form by one or more SP equipment and one or more MP equipment, finish the processing of Xin Lingdaili function and Media proxy function respectively, as shown in Figure 3, wherein SP and MP can be deployed in same region physically, also can be deployed in different regions.Because the relative Media Stream of signaling traffic is much smaller, so SP can be simultaneously and a plurality of MP collaborative works, to solve signaling traffic and the unbalanced problem of medium flow.
But in the distributed treatment process, because SP and MP are respectively according to self configuration process same call, so relevant configuration information of two equipment, need be consistent as qos policy information, security information, authentication information etc., otherwise will cause the processing confusion in the same call flow process, even conversation failure. in the prior art, need respectively SP and a plurality of MP to be configured processing, more loaded down with trivial details; And, when the configuration of a certain equipment changes, must upgrade other equipment, not easy care respectively in order to guarantee the consistency of distinct device configuration.
Summary of the invention
The objective of the invention is in order to overcome above-mentioned defective of the prior art, a kind of method and system of configuring distributed proxy server information are proposed, unify configuration information and send to each MP by SP, avoid disposing respectively SP and MP information, guarantee the consistency of SP and MP configuration information simultaneously.
Another object of the present invention is in order to overcome above-mentioned defective of the prior art, a kind of method and system of configuring distributed proxy server information are proposed, monitor the variation of each MP configuration information in real time by SP, the configuration information of SP and each MP keeps the collaborative of SP and MP configuration information synchronously.
For achieving the above object, the invention provides a kind of method of configuring distributed proxy server information, described acting server comprises a Xin Lingdaili equipment and at least one media agent device, said method comprising the steps of:
Step 2, the configuration information of described Xin Lingdaili equipment and media agent device is set with unified format on Xin Lingdaili equipment;
Step 3, Xin Lingdaili equipment are given described each media agent device with described configuration information synchronously by described secured communication channel;
Described configuration information is resolved and installed to step 4, described each media agent device.
In order to satisfy collaborative requirement, can also comprise after the described step 4:
Described Xin Lingdaili equipment is configuration information on described each media agent device of monitoring in real time, when configuration information changes on the media agent device, and the local configuration information of described Xin Lingdaili apparatus modifications, and execution in step 3 again.
Perhaps, in order to satisfy collaborative requirement, comprise after the described step 4:
When described Xin Lingdaili equipment received the configuring request of described media agent device transmission or receives the network management terminal command triggers, described Xin Lingdaili equipment was reset local configuration information, re-executes step 3.
A kind of system of configuring distributed proxy server information also is provided, described acting server comprises a Xin Lingdaili equipment and at least one media agent device, described Xin Lingdaili equipment is connected by a secured communication channel respectively with described each media agent device, described Xin Lingdaili equipment is used for being provided with unified format the configuration information of described Xin Lingdaili equipment and media agent device, and gives described each media agent device synchronously by described each secured communication channel respectively with described configuration information; Described each media agent device is used for sendaisle and sets up request, resolves and install described configuration information.
In order to satisfy collaborative requirement, can also include a real-time monitoring module in the equipment of Xin Lingdaili described in the said system, be used for regularly sending query requests to described media agent device by described secured communication channel, when configuration information changed on the media agent device, described Xin Lingdaili equipment was reset local configuration information.
Perhaps, in order to satisfy collaborative requirement, can also include a real-time monitoring module in the equipment of Xin Lingdaili described in the said system, be used to receive configuring request or the network management terminal command triggers that described media agent device sends, and instruct described Xin Lingdaili equipment to reset local configuration information.
