To combine the accompanying drawing in the embodiment of the invention below, the technical scheme in the embodiment of the invention is carried out clear, intactly description, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the present invention's protection.
The network scenarios of at first embodiment of the invention being used describes.The described Distributed Multi conference system of the embodiment of the invention comprises a plurality of zones; Each zone has at least one multipoint control unit; Each at least one terminal of multipoint control unit control is passed through the multipoint control unit cascade and is held trans-regional meeting between a plurality of zones.Multipoint control unit can be meant that MCU, MRS etc. have the equipment of multiple spot controlled function.With Fig. 1 is example; The Distributed Multi conference system comprises three zones, and zone one has MCU1 and a plurality of terminal, and zone two has MCU2 and a plurality of terminal; Zone three has MCU3 and a plurality of terminal; MCU1 and MCU2 physical connection, MCU1 and MCU3 physical connection are if MCU1 and MCU2 establish a communications link; MCU1 and MCU3 establish a communications link, and zone one, zone two and zone three pass through that MCU2 is connected with communication between the MCU1 and MCU1 is connected to hold with communication between the MCU3 and strides trizonal meeting so.
Describe in the face of management method, device, multipoint control unit and system in the Distributed Multi conference system of the embodiment of the invention down.
Management method in a kind of Distributed Multi conference system that the embodiment of the invention provides is as shown in Figure 2, comprising:
S201: obtain the topological relation of the multipoint control unit in the said Distributed Multi conference system, the topological relation of said multipoint control unit is used to represent the communication annexation between the multipoint control unit;
S202: the topological relation according to said acquisition carries out bookkeeping.
The topological relation of the multipoint control unit in the said Distributed Multi conference system can be meant whole topological relations of multipoint control unit, also can be meant the part topological relation of multipoint control unit.Still is example with Fig. 1, MCU2 both can only obtain its with MCU1 between the annexation of communicating by letter, also can obtain its with MCU1 between communicate by letter annexation and MCU1 and MCU3 between the annexation of communicating by letter.
When concrete the realization, can there be multiple mode to obtain the topological relation of the multipoint control unit in the said Distributed Multi conference system.For example, dispose the topological relation of the multipoint control unit in the said Distributed Multi conference system in advance in this locality, when the needs topological relation, obtain the topological relation of the multipoint control unit the pre-configured said Distributed Multi conference system from this locality.Again for example, other multipoint control units provide the topological relation of the multipoint control unit in the said Distributed Multi conference system, in other words, obtain the topological relation of the multipoint control unit in the said Distributed Multi conference system that other multipoint control units provide.When concrete the realization, there is multiple mode to obtain the topological relation of the multipoint control unit in the said Distributed Multi conference system that other multipoint control units provide, for example, to establishing a communications link with the multipoint control unit request that self has physical connection; Obtain the topological relation of the multipoint control unit in the said Distributed Multi conference system that said and the multipoint control unit that self has physical connection provide.To establishing a communications link and after start, to carry out with the multipoint control unit request that self has physical connection.
Need to prove that the topological relation that multipoint control unit uses can be static, also can be dynamic.Specifically; No matter be the topological relation that disposes the multipoint control unit in the said Distributed Multi conference system in advance in this locality; Still obtain the topological relation of the multipoint control unit the said Distributed Multi conference system from other multipoint control units; So long as obtained the topological relation of the multipoint control unit in the said Distributed Multi conference system for the first time; In the management process so afterwards, the topological relation of the multipoint control unit in the said Distributed Multi conference system both can remain unchanged, and also can obtain with the variation of the communication annexation between the multipoint control unit upgrading.The topological relation that multipoint control unit uses is maintenance static state or keeps dynamically can being decided according to the actual requirements by those skilled in the art.
When concrete the realization, can there be multiple mode to carry out bookkeeping according to the topological relation of said acquisition.Introduce several kinds of typical bookkeepings below.
First kind of mode
Behind the topological relation of the multipoint control unit in obtaining the Distributed Multi conference system, can give other multipoint control units synchronously with the topological relation of said acquisition.Concrete; With the multipoint control unit that self has physical connection can be to self sending the request that establishes a communications link; Promptly; Obtain the request that establishes a communications link of sending, afterwards, the topological relation of said acquisition is provided to said and the multipoint control unit that self has physical connection with the multipoint control unit that self has physical connection.With the multipoint control unit that self has physical connection to the opportunity of self sending the request that establishes a communications link can be with the multipoint control unit start that self has physical connection after.
With Fig. 5 is example; Suppose that the Distributed Multi conference system comprised MCU1, MCU2, MCU3, MCU4 and MCU5 originally, the topological relation that MCU4 obtains is: MCU1 and MCU2 have that the annexation of communication, MCU1 and MCU4 have the annexation of communication, MCU3 and have the annexation of communication with MCU4, MCU4 has the annexation of communication with MCU5.After MCU6 sent the request that establishes a communications link to MCU4, MCU4 can offer MCU6 with the above topology relation of its acquisition.
The second way
If the topological relation of the multipoint control unit in the Distributed Multi conference system changes, then can upgrade the topological relation of the multipoint control unit in the said Distributed Multi conference system.The topological relation of multipoint control unit changes for example for having new multipoint control unit to add topology or having multipoint control unit to withdraw from situations such as topology.Concrete; When with self have after the multipoint control unit that is connected of communication upgrades the topological relation of the multipoint control unit in the said Distributed Multi conference system; Can the topological relation of the multipoint control unit in the said Distributed Multi conference system after upgrading be offered self; That is, can obtain with self have the renewal that the multipoint control unit that is connected of communication provides after said Distributed Multi conference system in the topological relation of multipoint control unit; After obtaining to send the request that establishes a communications link, said and the multipoint control unit that self has physical connection are joined the topological relation of the multipoint control unit in the said Distributed Multi conference system with the multipoint control unit that self has physical connection; When confirming and self having after multipoint control unit that communication is connected withdraws from topology, with deleting in the topological relation that withdraws from the topological multipoint control unit of multipoint control unit from said Distributed Multi conference system.
With Fig. 5 and first kind of mode is example; After MCU6 joins topological relation; MCU4 is increased to itself and the annexation of communicating by letter that MCU6 has in the topological relation that MCU4 had originally, and the topological relation after will upgrading or MCU4 give MCU1, MCU3 and MCU5 synchronously with the annexation of communicating by letter that MCU6 has.Suppose that again MCU6 withdraws from topological relation, MCU4 deletes it in the topological relation that it has with the annexation of communicating by letter that MCU6 has so, and the topological relation after will upgrading is given MCU1, MCU3 and MCU5 synchronously.
Certainly, the topological relation that upgrades the multipoint control unit in the said Distributed Multi conference system can also be other situations, and for example the communication annexation between the multipoint control unit changes, and illustrates no longer one by one here.
After upgrading the topological relation of the multipoint control unit in the said Distributed Multi conference system, can the topological relation of the multipoint control unit in the said Distributed Multi conference system after the said renewal be given synchronously and self has a multipoint control unit that communication is connected.In fact; Each multipoint control unit in the topological relation can be given the topological relation of the multipoint control unit in the said Distributed Multi conference system after upgrading synchronously and self has the multipoint control unit that communication is connected, so that the topological relation of the multipoint control unit in the said Distributed Multi conference system of the current use of all multipoint control units in the topological relation all is consistent.
Because the task of a core of Distributed Multi conference system is held the video and/or audio meeting exactly, so the operation of calling a meeting is an important operation in the bookkeeping of Distributed Multi conference system.
The third mode
When needs are called a meeting,, send the meeting request to the corresponding multipoint control unit in terminal that needs participate in a conference according to the topological relation that obtains.The corresponding multipoint control unit in the terminal that participates in a conference if desired is not and the multipoint control unit that self has the annexation of communicating by letter; Then according to the topological relation of said acquisition; To sending the meeting request, directly or indirectly be transmitted to the corresponding multipoint control unit in terminal that need participate in a conference with the multipoint control unit request of will having a meeting that self has the communication annexation by said with the multipoint control unit that self has the annexation of communicating by letter.Described here is meant indirectly; If said do not have the annexation of communication with the multipoint control unit multipoint control unit corresponding with the terminal that need participate in a conference that self has the communication annexation; So said will the meeting with the multipoint control unit that self has the annexation of communicating by letter asks to be transmitted to the multipoint control unit that has the annexation of communicating by letter with it; The corresponding multipoint control unit in terminal that need participate in a conference by that analogy, until meeting request arrival.The corresponding multipoint control unit in the terminal that participates in a conference if desired is and the multipoint control unit that self has the annexation of communicating by letter so directly to send the meeting request to it and get final product.Also can explain indirectly hereinafter described with reference to this.
After the corresponding multipoint control unit in terminal that needs participate in a conference sent the meeting request, directly or indirectly the meeting that returns of the multipoint control unit of the acquisition terminal correspondence that need participate in a conference responded.Concrete, the corresponding multipoint control unit in the terminal that need participate in a conference can be controlled the terminal that needs participate in a conference after receiving the meeting request; For example; The terminal that needs are participated in a conference joins in the meeting, add successfully after, the meeting response that returns success to the multipoint control unit that sends meeting request; Otherwise, return the meeting response of failure.Certainly, the meeting response also can be carried other information, illustrates no longer one by one here.
When obtaining with meeting request that the multipoint control unit that self has the annexation of communicating by letter sends; If all terminals that self controls need not participate in a conference; Then can said meeting request directly or indirectly be transmitted to the corresponding multipoint control unit in terminal that need participate in a conference according to the topological relation of said acquisition.After said meeting request directly or indirectly being transmitted to the multipoint control unit of the terminal correspondence that need participate in a conference; When meeting response that the corresponding multipoint control unit in terminal that direct or indirect acquisition need participate in a conference sends, can said meeting response be transmitted to said that send the meeting request and the multipoint control unit that self has the annexation of communicating by letter.
After meeting is held successfully, can exchange the meeting situation such as state in meeting-place separately each other between each multipoint control unit, like this, each multipoint control unit in the Distributed Multi conference system can provide whole meeting situation to the keeper.
With Fig. 5 is example; Suppose that MCU1 need convene terminal and the meeting of the terminal under the MCU6 under the MCU3; MCU1 sends the meeting request to MCU4, and MCU4 can find not convene the terminal meeting under it, but convenes terminal and the meeting of the terminal under the MCU6 under the MCU3; So the MCU4 request of will having a meeting is transmitted to MCU3 and MCU6.If MCU3 joins in the meeting the success of the terminal under it, MCU6 joins in the meeting the success of the terminal under it, and MCU3 and MCU6 can respond to the meeting that MCU4 returns success so, and MCU4 returns to MCU1 with the meeting response of success again.
The 4th kind of mode
Sometimes, the keeper need check the meeting situation, and at this moment, the multipoint control unit that the keeper logined should offer the keeper with the meeting situation.Concrete, when obtaining Admin Access's self request, confirm said keeper's access rights, the topological relation and the meeting situation of the multipoint control unit that adapts with its access rights is provided to said keeper.To the keeper topological relation of multipoint control unit being provided can be to point to the topological relation that the keeper shows multipoint control unit, and to the keeper meeting situation being provided can be to point to the keeper to show situation such as conference site state.Provide the topological relation of the multipoint control unit that adapts with its access rights and meeting situation specifically can comprise to said keeper:, then whole topological relations of the multipoint control unit in the said Distributed Multi conference system and the meeting situation on said whole topological relations to be provided to said keeper if said keeper has the authority of all multipoint control units in the said Distributed Multi conference system of visit; If said keeper only has the authority of multipoint control unit in the zone at visit self place, topological relation and the meeting situation on the topological relation at the multipoint control unit in the zone at said self place of multipoint control unit in the zone at self place is provided to said keeper then.
Keeper's authority can be according to actual needs and flexible configuration, and keeper's authority for example comprises equipment control and conference management.Whether the equipment control authority can control and management person can visit multipoint control unit and multipoint control unit is configured.Whether the conference management authority can control and management person can be controlled the meeting that is cascaded on other multipoint control units.For example, suppose that keeper A can visit other regional multipoint control units, and can control the meeting that is cascaded on other regional multipoint control units.Sign in to the multipoint control unit of one's respective area as keeper A after, the interface that keeper A uses can show the equipment connection status that whole network is current, and keeper A can directly get into any multipoint control unit and carry out maintenance and management.For the meeting that is cascaded to a plurality of multipoint control units, keeper A can see meeting and the site list on each multipoint control unit, can control the meeting on each multipoint control unit.Suppose that keeper B can only visit multipoint control unit and the meeting in the one's respective area.Sign in to the multipoint control unit of one's respective area as keeper B after; Keeper B can only see the situation of each multipoint control unit of one's respective area; For trans-regional meeting, keeper B can only see the meeting situation such as meeting-place of one's respective area, and can't see other regional meeting situation such as meeting-place.
In addition, the keeper can manage another multipoint control unit on a multipoint control unit.Concrete; As the keeper who obtains to sign in to self or sign in to other multipoint control units during to the management information of a multipoint control unit; According to the topological relation of said acquisition, said management information directly or indirectly is transmitted to the multipoint control unit that said management information finally need arrive.Still be example with Fig. 5, suppose that the keeper need manage MCU6 on MCU1, MCU1 produces the management information of keeper to MCU6, and MCU1 offers MCU4 with management information, and MCU4 is transmitted to MCU6 with management information again.
Need to prove that above-mentioned several bookkeepings can carry out respectively in practical application.
Need to prove that also the executive agent of S201 and S202 can be a multipoint control unit.
Method corresponding shown in Figure 2, the embodiment of the invention provides the management devices in a kind of Distributed Multi conference system.As shown in Figure 3; Said management devices comprises: obtain unit 31; Be used for obtaining the topological relation of the multipoint control unit of said Distributed Multi conference system, the topological relation of said multipoint control unit is used to represent the communication annexation between the multipoint control unit; Administrative unit 32 is used for carrying out bookkeeping according to the topological relation that said acquisition unit 31 obtains.
The topological relation of the multipoint control unit in the said Distributed Multi conference system can be meant whole topological relations of multipoint control unit, also can be meant the part topological relation of multipoint control unit.Still is example with Fig. 1, MCU2 both can only obtain its with MCU1 between the annexation of communicating by letter, also can obtain its with MCU1 between communicate by letter annexation and MCU1 and MCU3 between the annexation of communicating by letter.
Obtaining unit 31 can have multiple mode to obtain the topological relation of the multipoint control unit in the said Distributed Multi conference system.For example; Obtain unit 31 obtains the multipoint control unit the pre-configured said Distributed Multi conference system from this locality topological relation; Perhaps, obtain the topological relation that unit 31 obtains the multipoint control unit in the said Distributed Multi conference system that other multipoint control units provide.When concrete the realization; Obtaining unit 31 can have multiple mode to obtain the topological relation of the multipoint control unit in the said Distributed Multi conference system that other multipoint control units provide; For example; The multipoint control unit request that has physical connection to the multipoint control unit with device shown in Figure 3 place establishes a communications link, and obtains the topological relation of the multipoint control unit in the said Distributed Multi conference system that multipoint control unit that multipoint control unit that device said and shown in Figure 3 belongs to has physical connection provides.When concrete the realization, obtaining unit 31 can comprise: request subelement 311, and the multipoint control unit request that is used for having to the multipoint control unit with device place shown in Figure 3 physical connection establishes a communications link; Obtain subelement 312; Be used at the described request subelement after the multipoint control unit request that the multipoint control unit with device shown in Figure 3 place has a physical connection establishes a communications link, obtain the topological relation of the multipoint control unit in the said Distributed Multi conference system that multipoint control unit that multipoint control unit that device said and shown in Figure 3 belongs to has physical connection provides.Obtaining unit 31 establishes a communications link and can carry out in the multipoint control unit start back at device place shown in Figure 3 to the multipoint control unit request that the multipoint control unit with device place shown in Figure 3 has physical connection.
Need to prove that the topological relation that obtains unit 31 acquisitions can be static, also can be dynamic.Specifically; After obtaining the topological relation of the multipoint control unit in the said Distributed Multi conference system of unit 31 acquisitions; The topological relation of the multipoint control unit in the said Distributed Multi conference system both can remain unchanged, and also can obtain with the variation of the communication annexation between the multipoint control unit upgrading.
After obtaining unit 31 acquisition topological relations, administrative unit 32 can be given other multipoint control units synchronously with the topological relation of said acquisition.When concrete the realization, administrative unit 32 can comprise the first synchronous subelement 321, is used for after obtaining unit 31 acquisition topological relations, giving other multipoint control units synchronously with the topological relation of said acquisition.Concrete; The multipoint control unit that has physical connection with the multipoint control unit at device shown in Figure 3 place can send the request that establishes a communications link to the multipoint control unit at device place shown in Figure 3; Promptly; Obtain unit 31 and obtain the request that establishes a communications link that multipoint control unit that multipoint control unit with device shown in Figure 3 place has physical connection sends; Afterwards, administrative unit 32 multipoint control unit from a physical connection to the multipoint control unit at device said and shown in Figure 3 place that have provides the topological relation of said acquisition.The multipoint control unit that has a physical connection with the multipoint control unit at device shown in Figure 3 place can be after the multipoint control unit with device place shown in Figure 3 has the multipoint control unit start of physical connection to the opportunity that the multipoint control unit at device place shown in Figure 3 sends the request that establishes a communications link.
If the topological relation of the multipoint control unit in the said Distributed Multi conference system changes, then said administrative unit 32 is upgraded the topological relation of the multipoint control unit in the said Distributed Multi conference system.When concrete the realization; Administrative unit 32 can comprise upgrades subelement 322; Change if be used for the topological relation of the multipoint control unit of said Distributed Multi conference system, then upgrade the topological relation of the multipoint control unit in the said Distributed Multi conference system.The topological relation of multipoint control unit changes for example for having new multipoint control unit to add topology or having multipoint control unit to withdraw from situations such as topology.Concrete; When the multipoint control unit with device shown in Figure 3 place has after multipoint control unit that communication is connected upgrades the topological relation of the multipoint control unit in the said Distributed Multi conference system; Can the topological relation of the multipoint control unit in the said Distributed Multi conference system after upgrading be offered the multipoint control unit at device place shown in Figure 3; That is, obtain unit 31 can obtain with said Distributed Multi conference system after the multipoint control unit at device shown in Figure 3 place has the renewal that multipoint control unit that communication is connected provides in the topological relation of multipoint control unit; After obtaining unit 31 and obtaining multipoint control unit that multipoint control unit with device shown in Figure 3 place has physical connection and send the request that establishes a communications link, the multipoint control unit that the multipoint control unit that administrative unit 32 can device said and shown in Figure 3 belongs to have a physical connection joins the topological relation of the multipoint control unit in the said Distributed Multi conference system; When administrative unit 32 is confirmed to have after multipoint control unit that communication is connected withdraws from topology with the multipoint control unit at devices shown in Figure 3 place, administrative unit 32 will withdraw from the topological relation of the topological multipoint control unit of multipoint control unit from said Distributed Multi conference system and delete.Certainly, the topological relation that administrative unit 32 is upgraded the multipoint control unit in the said Distributed Multi conference system can also be other situations, illustrates no longer one by one here.
After administrative unit 32 was upgraded the topological relation of the multipoint control unit in the said Distributed Multi conference system, administrative unit 32 can be given the topological relation of the multipoint control unit in the said Distributed Multi conference system after the said renewal with the multipoint control unit at device shown in Figure 3 place synchronously had the multipoint control unit that communication is connected.When concrete the realization; Administrative unit 32 can comprise the second synchronous subelement 323; Be used for after said renewal subelement upgrades the topological relation of multipoint control unit of said Distributed Multi conference system, the topological relation of the multipoint control unit in the said Distributed Multi conference system after the said renewal is given synchronously and self had a multipoint control unit that communication is connected.In fact; Each multipoint control unit in the topological relation can be given the topological relation of the multipoint control unit in the said Distributed Multi conference system after upgrading synchronously and self has the multipoint control unit that communication is connected, so that the topological relation of the multipoint control unit in the said Distributed Multi conference system of the current use of all multipoint control units in the topological relation all is consistent.
When the multipoint control unit at device place shown in Figure 3 need be called a meeting, said administrative unit 32 can be sent the meeting request to the corresponding multipoint control unit in terminal that needs participate in a conference according to the topological relation of said acquisition.When concrete the realization, administrative unit 32 can comprise request subelement 324, is used for when needs are called a meeting, and according to the topological relation of said acquisition, sends the meeting request to the corresponding multipoint control unit in terminal that needs participate in a conference.The corresponding multipoint control unit in the terminal that participates in a conference if desired is not the multipoint control unit that has the annexation of communicating by letter with the multipoint control unit at device shown in Figure 3 place; Then administrative unit 32 can be according to the topological relation of said acquisition; The multipoint control unit that has the annexation of communicate by letter to the multipoint control unit with device shown in Figure 3 place sends the meeting request, and the multipoint control unit that has an annexation of communicating by letter by the multipoint control unit at device place said with shown in Figure 3 will be had a meeting and asked directly or indirectly to be transmitted to the corresponding multipoint control unit in terminal that need participate in a conference.Described here is meant indirectly; If the multipoint control unit at device said with shown in Figure 3 place has the multipoint control unit multipoint control unit corresponding with the terminal that need participate in a conference of communication annexation and does not have the annexation of communication; The multipoint control unit request of will having a meeting that the multipoint control unit at device place so said with shown in Figure 3 has the annexation of communicating by letter is transmitted to the multipoint control unit that has the annexation of communicating by letter with it; The corresponding multipoint control unit in terminal that need participate in a conference by that analogy, until meeting request arrival.The corresponding multipoint control unit in the terminal that participates in a conference if desired is the multipoint control unit that has the annexation of communicating by letter with the multipoint control unit at device shown in Figure 3 place, so directly sends the meeting request to it and gets final product.Also can explain indirectly hereinafter described with reference to this.
Administrative unit 32 after the corresponding multipoint control unit in terminal that needs participate in a conference sends the meeting request, obtain unit 31 directly or indirectly the meeting that returns of the multipoint control unit of the acquisition terminal correspondence that need participate in a conference respond.Concrete, the corresponding multipoint control unit in the terminal that need participate in a conference can be controlled the terminal that needs participate in a conference after receiving the meeting request; For example; The terminal that needs are participated in a conference joins in the meeting, add successfully after, the meeting response that returns success to the multipoint control unit that sends meeting request; Otherwise, return the meeting response of failure.Certainly, the meeting response also can be carried other information, illustrates no longer one by one here.
When said acquisition unit 31 also obtains to have the meeting request that the multipoint control unit of the annexation of communicating by letter sends with the multipoint control unit at device shown in Figure 3 place; If all terminals of the multipoint control unit control at device shown in Figure 3 place need not participate in a conference; Then said administrative unit 32 can directly or indirectly be transmitted to said meeting request the corresponding multipoint control unit in terminal that need participate in a conference according to the topological relation of said acquisition.When concrete the realization; Administrative unit 32 can comprise that first transmits subelement 325; Be used for when meeting request that said acquisition unit also obtains to send with the multipoint control unit that self has the annexation of communicating by letter; If all terminals that self controls need not participate in a conference, then, said meeting request directly or indirectly is transmitted to the corresponding multipoint control unit in terminal that need participate in a conference according to the topological relation of said acquisition.After administrative unit 32 directly or indirectly is transmitted to the multipoint control unit of the terminal correspondence that need participate in a conference with said meeting request; When obtaining the meeting response that the corresponding multipoint control unit in terminal that unit 31 direct or indirect acquisitions need participate in a conference sends, administrative unit 32 can be transmitted to said that send that meeting asks and the multipoint control unit that self has the annexation of communicating by letter with said meeting response.
After meeting is held successfully, can exchange the meeting situation such as state in meeting-place separately each other between each multipoint control unit, like this, each multipoint control unit in the Distributed Multi conference system can provide whole meeting situation to the keeper.
When said acquisition unit 31 also obtains the request of multipoint control unit at Admin Access's device shown in Figure 3 place; Said administrative unit 32 can at first be confirmed said keeper's access rights, and the topological relation and the meeting situation of the multipoint control unit that adapts with its access rights is provided to said keeper afterwards again.When concrete the realization, administrative unit 32 can comprise: scope check subelement 326 is used for when said acquisition unit also obtains Admin Access's self request, confirming said keeper's access rights; Subelement 327 is provided, is used for providing the topological relation and the meeting situation of said scope check subelement 326 multipoint control unit that adapts with said administrator access that confirm to said keeper.To the keeper topological relation of multipoint control unit being provided can be to point to the topological relation that the keeper shows multipoint control unit, and to the keeper meeting situation being provided can be to point to the keeper to show situation such as conference site state.Administrative unit 32 provides the topological relation of the multipoint control unit that adapts with its access rights and meeting situation specifically can comprise to said keeper: if said keeper has the authority of all multipoint control units in the said Distributed Multi conference system of visit, then administrative unit 32 provides whole topological relations of the multipoint control unit in the said Distributed Multi conference system and the meeting situation on said whole topological relations to said keeper; If said keeper only has the authority of multipoint control unit in the zone at visit self place, then administrative unit 32 provides the topological relation and the meeting situation on the topological relation of the multipoint control unit in the zone at said self place of multipoint control unit in the zone at self place to said keeper.
Keeper's authority can be according to actual needs and flexible configuration, and keeper's authority for example comprises equipment control and conference management.Whether the equipment control authority can control and management person can visit multipoint control unit and multipoint control unit is configured.Whether the conference management authority can control and management person can be controlled the meeting that is cascaded on other multipoint control units.For example, suppose that keeper A can visit other regional multipoint control units, and can control the meeting that is cascaded on other regional multipoint control units.Sign in to the multipoint control unit of one's respective area as keeper A after, the interface that keeper A uses can show the equipment connection status that whole network is current, and keeper A can directly get into any multipoint control unit and carry out maintenance and management.For the meeting that is cascaded to a plurality of multipoint control units, keeper A can see meeting and the site list on each multipoint control unit, can control the meeting on each multipoint control unit.Suppose that keeper B can only visit multipoint control unit and the meeting in the one's respective area.Sign in to the multipoint control unit of one's respective area as keeper B after; Keeper B can only see the situation of each multipoint control unit of one's respective area; For trans-regional meeting, keeper B can only see the meeting situation such as meeting-place of one's respective area, and can't see other regional meeting situation such as meeting-place.
In addition; The keeper who also obtains to sign in to the multipoint control unit at device place shown in Figure 3 or sign in to other multipoint control units when said acquisition unit 31 is during to the management information of a multipoint control unit; Said administrative unit 32 can directly or indirectly be transmitted to the multipoint control unit that said management information finally need arrive with said management information according to the topological relation of said acquisition.When concrete the realization; Administrative unit can comprise that second transmits subelement 328; The keeper who is used for also obtaining to sign in to self or sign in to other multipoint control units when said acquisition unit is during to the management information of a multipoint control unit; According to the topological relation of said acquisition, said management information directly or indirectly is transmitted to the multipoint control unit that said management information finally need arrive.
