Embodiment
The present invention proposes a kind of call connection establishing method based on mutual-control cascade conference, and the method is applied to comprise in the video conference of at least cross complaint cascade of two-stage MCU that this two-stage MCU is the MCU of subordinate and higher level MCU, and the MCU of subordinate management has a plurality of meeting-place terminal MT.Take Fig. 1 as grid of reference model schematic diagram, higher level MCU is one-level MCU (MCU1), and the MCU of subordinate is secondary MCU (MCU2.1, MCU2.2), and the meeting-place terminal of MCU2.1 management is respectively MT2.1.I, MT2.1.2, MT2.1.3.
Be not limited to the MCU networking of two-stage in the practical application, as on the basis of Fig. 1, three grades of MCU can also be arranged, this moment, higher level MCU was one-level MCU, the MCU of subordinate can be secondary MCU or three grades of MCU, and the processing of processing mode and two-stage MCU is similar, repeats no more among the present invention.
When higher level MCU need to establish call connection with the MT of the MCU of subordinate management, then higher level MCU and the MCU of subordinate establish call connection, the MT of the MCU of subordinate and management establishes call connection, establish call connection such as MCU1 and MCU2.1, MCU2.1 and MT2.1.1 (or MT2.1.2, MT2.1.3) establish call connection, the process that among the present invention MCU1 and MCU2.1 is established call connection is elaborated, and the process that MCU2.1 and MT2.1.1 establish call connection is given unnecessary details no longer in detail.
As shown in Figure 2, should may further comprise the steps based on the call connection establishing method of mutual-control cascade conference:
When virtual site is set, the IP address of virtual site is identical with the IP address of the MCU of subordinate, the E164 number of virtual site (is used for virtual site and GK (Gatekeeper, the gatekeeper) (the Remote Access Service of the RAS between, remote access service) mutual) different from the E164 number of the MCU of subordinate, and the E164 number between each virtual site is different, and represents that by designated identification (as identifying 2) the meeting-place type is virtual site.
Among the present invention, for a plurality of MT under MCU1 and the MCU2.1 management are established call connection, then MCU2.1 is on the basis in true meeting-place (being existing meeting-place MCU2.1), also need for each MT virtual site to be set, this virtual site is used for establishing call connection between MCU1 and MCU2.1 by virtual site in the situation that MCU1 and MCU2.1 have established call connection by true meeting-place.
In order to realize the cross complaint concatenation technology, the MCU of subordinate needs the synchronously meeting field information of self of superior MCU, carries the information (such as true meeting field information and virtual site information) of the MCU of subordinate and the information of each MT that the MCU of subordinate manages in this meeting field information.

When higher level MCU need to the MT (such as MT2.1.1) of the MCU of subordinate management when establishing call connection, owing to be that call connection is set up process first, then the MCU of subordinate can establish call connection by true meeting-place and higher level MCU, and this process and existing procedure are similar, do not repeat them here.
Afterwards, when the MCU of subordinate establishes call connection with higher level MCU, if higher level MCU also needs to establish call connection with the 2nd MT (such as MT2.1.2) of the MCU of subordinate management, then carry out subsequent step.Wherein, higher level MCU knows that by the MCU relational tree MT2.1.2 is the MCU2.1 management.
Higher level MCU can set up by the information of safeguarding in the MCU relational tree mapping relations of the virtual site of the 2nd MT and the MCU of subordinate.For example, when needs established call connection with MT2.1.2, by the MCU relational tree of question blank 2, higher level MCU can set up the mapping relations of MT2.1.2 and MCU2.1.2.
Among the present invention, when also needing the 2nd MT with the MCU of subordinate management to establish call connection after higher level MCU establishes call connection by the MCU of subordinate and a MT, then higher level MCU determines that the MCU of subordinate need enable virtual site superior MCU and send setup requests.For example, when MCU1 need to establish call connection with MT2.1.2, learn that by searching the MCU relational tree MT2.1.2 is positioned under the MCU2.1, and learn that by the channel information of checking MCU2.1 the existing passage of opening is for the data of broadcasting MT2.1.1 between MCU1 and the MCU2.1, then MCU1 determines that MCU2.1 need enable virtual site.
Afterwards, higher level MCU sets up the mapping relations of the virtual site of the 2nd MT and the MCU of subordinate, and enables the anonymous site with restrictive condition, and this restrictive condition sends setup requests for the virtual site that only allows to meet mapping relations as anonymous site.As shown in table 3, be a kind of mapping relations.
Table 3
| Virtual site | Affiliated MCU | Higher level MCU | The meeting-place terminal |
| MCU2.1.2 | MCU2.1 | MCU1 | MT2.1.2 |
After receiving request message, if the MCU of subordinate knows that self establishes call connection by true meeting-place and higher level MCU, then the MCU of subordinate determines that need to enable virtual site sets up new call connection.Afterwards, owing to record the corresponding relation of the 2nd MT and virtual site among the MCU of subordinate, then the MCU of subordinate can determine that virtual site is MCU2.1.2 according to the MT2.1.2 that carries in the request message.
The MCU of subordinate is specially by the process that virtual site superior MCU sends setup requests: the MCU of subordinate enables VMT (Virtual Manufacturing Technology, Virtual Manufacture) process is as virtual site, set up the VMT process to TCP (the Transmission Control Protocol between the process (being the call proceeding in true meeting-place) of the current call connection of having set up, transmission control protocol) connects (this TCP connects the data that are used for sending the 2nd MT), and by VMT process superior MCU transmission setup requests (setup message), portability virtual site information in this setup requests is such as virtual site MCU2.1.2, the information such as E164 number 22212.
Information by the virtual site that carries in the setup requests, and the mapping relations of table 3 record, higher level MCU can carry out authentication to the MCU of subordinate, if the information of the virtual site that carries in the discovery setup requests satisfies mapping relations, then allow the MCU of subordinate affiliation, be that higher level MCU and the MCU of subordinate establish call connection, and the 2nd the MT final and MCU of subordinate management establish call connection.
Need to prove, the above-mentioned process that establishes call connection can for the data of MT corresponding to the higher level MCU broadcasting MCU of subordinate or, higher level MCU watches the data of MT corresponding to the MCU of subordinate.For example, MCU1 is by the data of true meeting-place broadcasting MT2.1.1, and the data of watching MT2.1.2 by virtual site; The data that MCU1 watches MT2.1.1 by true meeting-place, and the data by virtual site broadcasting MT2.1.2.
After higher level MCU and the MCU of subordinate establish call connection, can negotiate by the call signaling of Q931 H.245 address, set up the H245 control channel, and carry out the mutual of H245 signaling, carry out capability negotiation, open logical channel.Based on this, formed a higher level MCU to the MCU of subordinate virtual site to the MCU of subordinate to selecting to watch/path of broadcast site.
Among the present invention, when higher level MCU need to finish the call connection of the 2nd MT, higher level MCU closed the logical channel of VMT process, and discharge TCP and connect, and the deletion mapping relations; The MCU of subordinate discharges TCP and connects, and finishes the VMT process.
