Embodiment
As stated in the Background Art, traditional meeting heat that comprises active and standby MCU is equipped with in the system, spare MCU when conference initiation by the disposable appointment of system.In this case, especially when only having specified a spare MCU in the hot system fully of this meeting, if fault has appearred in this spare MCU, or this spare MCU and main lost efficacy and when causing can't carrying out information synchronization or information interaction between the active and standby MCU with the communication path message between the MCU-, lead and promptly be in not guard mode with MCU; Even in this system, specified a plurality of spare MCUs,, also can reduce the reliability that original meeting heat that comprises a plurality of spare MCUs is equipped with system if one of them or several spare MCU break down.
Technical scheme proposed by the invention is that a kind of improved meeting heat is equipped with model.When leading with MCU or conference management device discovery spare MCU fault, initiatively the MCU in current system sends consulting, seeks a new spare MCU, thereby has the spare MCU that compliance with system requires in the safeguards system always, makes the master be in guard mode with MCU.
In order to realize above-mentioned technique effect,, technical scheme of the present invention is done detailed description below in conjunction with concrete application scenarios.
At first, realize guarantee the main technical scheme that with MCU have the method for spare MCU by main with MCU by following examples explanation.
As shown in Figure 2, the invention provides a kind of the assurance and main have the method for spare MCU, be applied to comprise in the system of at least three MCU with MCU, wherein, a MCU be main be spare MCU with MCU, the 2nd MCU,, specifically may further comprise the steps:
Step S201, main heartbeat message with MCU and spare MCU hold period detect.
In the technical scheme of prior art, exist between the active and standby MCU periodic heartbeat message to detect equally, promptly in predetermined period, send handshake information and handshake response message mutually between the detected both sides.By this detection, spare MCU can be real-time the main operating state with MCU of monitoring, in case the master is broken down with MCU, then spare MCU switches to the main MCU pattern of using at once, the master who breaks down is all taken over the current meeting process of carrying of MCU, thereby ensure that the meeting process can be owing to main fault with MCU is affected.And, can take over main meeting process smoothly in order to realize spare MCU with MCU, information synchronization when also keeping really between the active and standby MCU, can preserve main accurately to guarantee spare MCU with up-to-date conferencing information and the resource status of MCU, thereby, can when the master is broken down with MCU, enable spare MCU immediately and take over the meeting process.
And in technical scheme of the present invention, above-mentioned periodic heartbeat message detection also further has main with the anti-monitoring function of MCU to spare MCU.Promptly the master in case spare MCU breaks down, then starts the selection process of spare MCU with the operating state that MCU can detect real-time monitoring spare MCU by this in the MCU except that main MCU of using and spare MCU that current system comprised.
Based on above-mentioned explanation, when interrupting appears in main the detection with the periodic heartbeat messages between MCU and the spare MCU, during the promptly main heartbeat response message that in predetermined period, does not receive spare MCU and returned with MCU, change step S202 over to.
Step S202, main with MCU sending a request message with all MCU MCU and the spare MCU in current system except that main.
In this step, the master sends a request message with all MCU MCU and the spare MCU except that main in current system by broadcast mode with MCU, inquire whether each MCU can become new spare MCU, difference according to preset strategy, main with comprising this master in the request message that MCU sent with the current resource information of MCU, also can not comprise this master and use the current resource information of MCU.
Above-mentioned resource information specifically is meant main conferencing information with MCU, and the current information of passing through this master with the conference terminal of meeting that MCU held and access is described.Information interaction form wherein specifically can adopt the H323 protocol message, also can adopt privately owned binary message or other can realize the form of constructed effect.Such variation does not influence protection scope of the present invention.
Use the current resource information of MCU according to whether comprising this master in the request message, can there be corresponding variation in follow-up step process, and such variation will describe in detail in subsequent step, and this all belongs to protection scope of the present invention.
Step S203, master receive the response message that each MCU returns according to default determination strategy with MCU.
Concrete, whether main with the current resource information of MCU according to comprising in the above-mentioned request message, the default determination strategy in this step also is divided into following two kinds of situations accordingly:
If comprise main in situation one request message with the current resource information of MCU, the MCU that then receives request message is according to own resource state and the current resource information of the main MCU of using that receives, judge whether self can be used as spare MCU, judge promptly whether its other resources is enough to bear the main meeting process of having carried out or being about to carry out with MCU.
Can be used as spare MCU if receive the MCU judgement of request message, then this MCU returns response message to main with MCU.
Cannot be if receive the MCU judgement of request message as spare MCU, then this MCU abandons request message.
If do not comprise the current resource information of the main MCU of using in situation two request messages, the MCU that then receives request message does not carry out the judgement of self, but directly returns response message to main with MCU, comprises the current resource information of this MCU in this response message.
In this case, the main effect that sends a request message with MCU be to make receive request message MCU to main with the current resource information of MCU feedback so that make main with MCU according to this Information Selection corresponding M CU as spare MCU.
Step S204, master select at least one MCU that returns response message as new spare MCU with MCU, and set up periodic heartbeat message with new spare MCU and detect.
Two kinds of situations among the corresponding above-mentioned steps S203, also there are following two kinds of situations accordingly in the treatment progress of this step:
Situation one among the corresponding step S203, the master receives the response message that at least one MCU that receives request message returns with MCU, does not comprise the current resource information of this MCU in this response message.In this case, all MCU that return response message judge through this MCU self, and affirmation can become spare MCU, so, the main MCU that uses can therefrom select at least one MCU to become spare MCU directly according to predetermined strategy, and sends acknowledge message to selected MCU.After this MCU receives the confirmation message, the spare MCU state will self be switching to, and it is main with setting up periodic heartbeat message detection between the MCU, and, further this MCU also and main with setting up information synchronization between the MCU leads all conferencing informations and call information etc. are synchronized on the new spare MCU in real time with MCU.
In this case, main strategy with MCU selection spare MCU can comprise following several:
(1) select first other MCU that return response message that return response message as new spare MCU.
The MCU that such selection has guaranteed to become spare MCU responds the fastest, thereby, when breaking down, can take over main main as soon as possible with the meeting process on the MCU with MCU.
(2) select at least one and this master to belong to the MCU that returns response message of same service area as new spare MCU with MCU.
Such selection is the consideration for network service, the MCU that is in the same services district is that communication speed or network state all can be more similar, like this, switch to mainly when using MCU at spare MCU, the active conference process can not be affected because of the variation of network state.
In actual applications, the formulation of concrete selection strategy is not limited only to above-mentioned several, and the variation of selection strategy does not influence protection scope of the present invention.
On the other hand, the situation two among the corresponding above-mentioned steps S203, the master receives the response message that at least one MCU that receives request message returns with MCU, comprises the current resource information of this MCU in this response message.In this case, all MCU that receive request message are to the main response message that comprises self current resource information that sends with MCU, the MCU that promptly receives request message does not have the judgement of process self, and not all MCU that returns response message can become spare MCU.So the master need further judge and select with MCU.
Such judgement and selection can be that substep carries out, promptly earlier from returning the MCU of response message, all filter out the MCU that can be used as spare MCU, then, further according to default selection strategy, in can be used as the MCU of spare MCU, further select satisfactory at least one MCU to become spare MCU again.
Above-mentioned judgement and selection also can be to finish in a step, think that promptly the MCU that meets default selection strategy must become spare MCU, on this basis, main with MCU directly according to default selection strategy, in all return the MCU of response message, select at least one MCU to become spare MCU.
After finishing above-mentioned selection, the main MCU of using sends acknowledge message to selected MCU.After this MCU receives the confirmation message, the spare MCU state will self be switching to, and it is main with setting up periodic heartbeat message detection between the MCU, and, further this MCU also and main with setting up information synchronization between the MCU leads all conferencing informations and call information etc. are synchronized on the new spare MCU in real time with MCU.
In this case, main strategy with MCU selection spare MCU can comprise following several:
(1) main with the MCU resource information current according to the MCU that is comprised in the response message, select available resources and master to use the immediate MCU of current use resource of MCU as new spare MCU.
The resource that such selection can realize becoming among the MCU of spare MCU is mated with the resource status among the MCU with main most, thereby can not cause the waste of resource.
(2) main with the MCU resource information current according to the MCU that is comprised in the response message, select the maximum MCU of available resources as new spare MCU.
The resource that such selection can guarantee to become among the MCU of spare MCU is maximum, carries out resource requirement that heat be equipped with to main with MCU thereby there is sufficient resources to satisfy.
In actual applications, the formulation of concrete selection strategy is not limited only to above-mentioned several, and the variation of selection strategy does not influence protection scope of the present invention.
By the present invention, lead the state that can monitor spare MCU with MCU in real time, when spare MCU broke down, the master can seek a suitable MCU as spare MCU automatically with MCU, guaranteed that the master is in guard mode with MCU always.
Below, the application scenarios in conjunction with concrete further specifies the technical scheme that the invention described above proposed:
As shown in Figure 3, for a kind of assurance the proposed by the invention mainly has the method for spare MCU with MCU, this method is when spare MCU breaks down, in conjunction with the judgement of other MCU self, by main a kind of technical scheme of determining new spare MCU with MCU, specifically may further comprise the steps:
Step S301, main with (heartbeat message detection) interruption of shaking hands of periodic message between MCU and the spare MCU.
Concrete, the master sends handshake information with MCU to spare MCU, but does not receive the handshake response that spare MCU returns in the predetermined cycle, thus the master confirms that with MCU spare MCU breaks down, and starts the selection flow process of new spare MCU, changes step S302 over to.
Step S302, main broadcasting with MCU other MCU on network comprise main request message with the current resource information of MCU, seek new spare MCU.
As shown in Figure 3, in current system, with MCU, spare MCU, also comprise n MCU (that is, MCU1, MCU2......MCUn) except main.The master has the resource information of this master with MCU with MCU in the request message of each MCU broadcasting, the terminal information of this master with current meeting of holding of MCU and access has been described.Information interaction wherein can adopt the H323 agreement, also can adopt privately owned binary message.
Step S303, each MCU receive after the request message calculate whether can be used as spare MCU according to the ability of self.
Wherein, above-mentioned self ability comprises information such as having held how many meetings, remaining available resource.For example, the current resource information state of this caller MCU has been for having held a meeting, inserted 20 of the conference terminals of 2M, and remaining available resource can also hold 9 meetings, inserts 30 of the conference terminals of 2M at most.
In view of the above, whether the current resource status of MCU measurement self that receives request message can satisfy the requirement of this master with MCU, if the surplus resources of self can satisfy main requirement with MCU, judges that then self can become spare MCU, changes step S304 over to; On the contrary,, judge that then self can not become spare MCU, directly abandon this request message, do not do any response if the surplus resources of self cannot satisfy main requirement with MCU.
In the present embodiment, MCU1 confirms self can become spare MCU.
Step S304, MCU1 use the MCU feedback response message to main, and affirmation can become spare MCU.
Step S305, the main selection strategy of presetting with the MCU basis select at least one MCU as new spare MCU in returning the MCU of response message.
Because the MCU that returns response message judges through self, affirmation can become spare MCU, so, main with MCU directly the selection strategy preset of basis select a suitable MCU as spare MCU according to qualifications.Concrete selection strategy can for: select first MCU that responds, select the MCU of this service area etc., the variation of concrete selection strategy does not influence protection scope of the present invention.
In the present embodiment, the master selects MCU1 as spare MCU with MCU.
Step S306, master send acknowledge message with MCU to MCU1.
The master informs that by acknowledge message MCU1 is selected to for spare MCU with MCU.
Step S307, MCU1 switch to the spare MCU pattern.
Step S308, main with MCU and the detection of MCU1 startup heartbeat message.
By this step, realized again in the system between the active and standby MCU by the mutual inspection of heartbeat message, make mainly to be among the protection of spare MCU with MCU.
Step S309, master are synchronized to information such as all conferencing informations, call information on the MCU1 in real time with MCU.
By the present invention, lead the state that can monitor spare MCU with MCU in real time, when spare MCU broke down, in conjunction with the judgement of other MCU self, the master can seek a suitable MCU as spare MCU automatically with MCU, guaranteed that the master is in guard mode with MCU always.
Implement in the scene at another kind, as shown in Figure 4, for a kind of assurance the proposed by the invention mainly has the method for spare MCU with MCU, this method is when spare MCU breaks down, the main current state information that obtains each other MCU with MCU, and determine specifically to may further comprise the steps a kind of technical scheme of new spare MCU according to this information:
Step S401, main with (heartbeat message detection) interruption of shaking hands of periodic message between MCU and the spare MCU.
Concrete, the master sends handshake information with MCU to spare MCU, but does not receive the handshake response that spare MCU returns in the predetermined cycle, thus the master confirms that with MCU spare MCU breaks down, and starts the selection flow process of new spare MCU, changes step S402 over to.
Step S402, main with MCU other MCU broadcast request message on network seeks new spare MCU.
As shown in Figure 4, the main MCU of using is to all the MCU broadcast request message except that the master uses MCU and spare MCU.
After step S403, each MCU receive request message, return the response message that comprises the current resource information of this MCU with MCU to main.
Wherein, the current resource information of above-mentioned MCU comprises information such as having held how many meetings, remaining available resource.
Step S404, the main selection strategy of presetting with the MCU basis select at least one MCU as new spare MCU in returning the MCU of response message.
Because all MCU that receive request message are sending the response message that comprises self current resource information to main with MCU, so not all MCU that returns response message can become spare MCU.Therefore need further judge and select according to the current resource information of other MCU in the response message and default selection strategy with MCU.
The same with the reason of being set forth among the aforementioned embodiment, such processing can be that substep carries out, and also can be to finish in a step, and consequent scheme variation all belongs to protection scope of the present invention.
And concrete selection strategy can for: select available resources and main immediate other MCU of current use resource with MCU as new spare MCU, select other maximum MCU of available resources as new spare MCU etc., the variation of concrete selection strategy does not influence protection scope of the present invention.
In the present embodiment, the master selects MCU1 as spare MCU with MCU.
Step S405, master send acknowledge message with MCU to MCU1.
The master informs that by acknowledge message MCU1 is selected to for spare MCU with MCU.
Step S406, MCU1 switch to the spare MCU pattern.
Step S407, main with MCU and the detection of MCU1 startup heartbeat message.
Step S408, master are synchronized to information such as all conferencing informations, call information on the MCU1 in real time with MCU.
By the present invention; lead the state that can monitor spare MCU with MCU in real time, when spare MCU broke down, the master obtained the current resource information of other MCU automatically with MCU; and seek a suitable MCU in view of the above automatically as spare MCU, guarantee that the master is in guard mode with MCU always.
On this basis, the invention provides a kind of video conferencing system, as shown in Figure 5, comprise at least three MCU, wherein, a MCU is that the master is a spare MCU 52 with MCU51, the 2nd MCU, and MCU in addition all is designated MCU53, main heartbeat message with MCU51 and spare MCU 52 hold periods detects, and specifies as follows:
The master is used for when heartbeat message detects interruption at least with MCU51, send a request message to each MCU53, receive the response message that MCU53 returns, select at least one MCU53 that returns response message, and send acknowledge message to selected MCU53 as new spare MCU;
MCU53 electrically connects with MCU51 with main, is used to receive the main request message that sends with MCU51 at least, and sends response message to main with MCU51 according to preset strategy.
Wherein, in concrete application scenarios, the preset strategy that MCU53 adopted is specific as follows:
If it is main with the current resource information of MCU51 that the master comprises in the request message that MCU53 sends with MCU51, then MCU53 also is used for when judgement self can become spare MCU, sends response message to main with MCU51, or, when judgement self cannot become spare MCU, abandon above-mentioned request message;
If it is main with the current resource information of MCU51 that the master does not comprise in the request message that MCU53 sends with MCU51, then MCU53 also is used for comprising with the MCU51 transmission to the master response message of the current resource information of MCU53.
Further, MCU53 will self switch to the spare MCU state after receiving the main affirmation message that sends with MCU51, and sets up periodic heartbeat message detection and information synchronization with main with MCU51.
Need be pointed out that further that above-mentioned main MCU51, spare MCU 52 and the MCU53 of using is all a kind of MCU equipment on physical substance, just according to the functional role difference of being undertaken in video conferencing system, and produced concrete changes of function.
By the present invention; in above-mentioned video conferencing system, lead the state that to monitor spare MCU with MCU in real time, when spare MCU breaks down; the master can seek a suitable MCU as spare MCU automatically with MCU, guarantees that the master is in guard mode with MCU always.
On the other hand, based on technological thought of the present invention,, realize guaranteeing the main technical scheme that has the method for spare MCU with MCU by conference management equipment by following examples explanation in conjunction with concrete enforcement scene.
As shown in Figure 6, the invention provides a kind of the assurance and main have the method for spare MCU, be applied to comprise in the system of a conference management equipment and at least three MCU, wherein with MCU, the one MCU is that the master is a spare MCU with MCU, the 2nd MCU, specifically may further comprise the steps:
Step S601, main with between MCU and the spare MCU, and the heartbeat message of hold period detects between conference management equipment and the spare MCU.
As previously mentioned, detect by periodic heartbeat message between the active and standby MCU, the main operating state of the monitoring that spare MCU can be real-time with MCU, and, the information synchronization when also keeping really between the active and standby MCU.
And in technical scheme of the present invention, periodic heartbeat message detection between meeting management system and the spare MCU has further been proposed, this heartbeat message detects and makes conference management equipment have monitoring function to spare MCU, be that conference management equipment can be by the operating state of the real-time monitoring spare MCU of this detection, in case spare MCU breaks down, then in the MCU that current system comprised, start the selection process of spare MCU.
Based on above-mentioned explanation, periodic heartbeat messages between conference management equipment and spare MCU detects and occurs interrupting, promptly conference management equipment in predetermined period, do not receive spare MCU and returned the heartbeat response message time, change step S602 over to.
It is to be noted; because MCU all in the system in the conference management equipment control; as long as wherein there is a spare MCU to break down; conference management equipment just will start the selection process of spare MCU; certainly, if a plurality of spare MCU breaks down simultaneously, can think that conference management equipment has started the process of a plurality of selection spare MCUs simultaneously; the process of selecting a plurality of spare MCUs simultaneously of yet can having thought the conference management device start, such variation does not influence protection scope of the present invention.
Step S602, conference management equipment calculate the MCU that can be used as new spare MCU according to main current resource information with MCU, and send a request message to the MCU that calculates.
Because the resource information of all MCU in the system in the real-time management of conference management equipment; so; conference management equipment removes to mate each MCU according to main with the current resource information of MCU; judge whether each MCU can become spare MCU; concrete determination strategy can be whether the available resources of each MCU can carry the current meeting process of the main MCU of using; whether the available resources that also can be each MCU are greater than main maximum resource value with MCU, and the variation of specific strategy does not influence protection scope of the present invention.
In this step, conference management equipment goes out the master by broadcast mode and sends a request message with all MCU outside MCU and the spare MCU in current system, inquire whether each MCU can become new spare MCU, difference according to preset strategy, can comprise the current resource information of the main MCU of using in the request message that conference management equipment is sent, also can not comprise this master and use the current resource information of MCU.
Above-mentioned resource information specifically is meant main conferencing information with MCU, and the current information of passing through this master with the conference terminal of meeting that MCU held and access is described.Information interaction form wherein specifically can adopt the H323 protocol message, also can adopt privately owned binary message or other can realize the form of constructed effect.Such variation does not influence protection scope of the present invention.
Use the current resource information of MCU according to whether comprising this master in the request message, can there be corresponding variation in follow-up step process, and such variation will describe in detail in subsequent step, and this all belongs to protection scope of the present invention.
Step S603, conference management equipment receive the MCU basis that respectively receives request message and preset the response message that determination strategy is returned.
Concrete, whether main with the current resource information of MCU according to comprising in the above-mentioned request message, the default determination strategy in this step also is divided into following two kinds of situations accordingly:
If comprise main in situation one request message with the current resource information of MCU, the MCU that then receives request message is according to own resource state and the main current resource information with MCU that receives, judge whether self can be used as spare MCU, what such judgement can think that spare MCU that conference management equipment is carried out selects examines.
Self can be used as spare MCU if receive the MCU judgement of request message, then send response message to conference management equipment.
Self cannot be if receive the MCU judgement of request message as spare MCU, then this MCU abandons request message.
If do not comprise the current resource information of the main MCU of using in situation two request messages, the MCU that then receives request message does not carry out the judgement of self, but directly sends response message to conference management equipment.
In this case, the effect that conference management equipment sends a request message is whether the response speed or the checking MCU that test MCU are in normal operating state, so that make the suitable MCU of conference management choice of equipment as spare MCU.
The difference of this step and aforesaid step S203 is, above-mentioned which kind of situation no matter can not comprise the current resource information of MCU in the received response message of conference management equipment.This is a resource information of all MCU in the system because of real-time management in the conference management equipment, need not to obtain separately by other modes.
Step S604, at least one MCU that returns response message of conference management choice of equipment be as new spare MCU, and set up periodic heartbeat message with new spare MCU and detect.
Concrete, conference management equipment informs that by sending acknowledge message at least one MCU that is selected to spare MCU this MCU is as new spare MCU.
Because conference management equipment had before carried out the calculating whether each MCU can become spare MCU, so, in this step, all response messages that conference management equipment is received all are that the MCU that can become spare MCU sends, therefore, conference management equipment can directly carry out the selection of spare MCU according to default selection strategy, and concrete selection strategy is as follows:
(1) first other MCU that return response message that return response message of conference management choice of equipment are as new spare MCU.
(2) the conference management choice of equipment at least one belong to other MCU that return response message of same service area as new spare MCU with main with MCU.
(3) conference management choice of equipment available resources use immediate other MCU of current use resource of MCU as new spare MCU with the master.
(4) other MCU that conference management choice of equipment available resources are maximum are as new spare MCU.
Embodiment is described as described above for the purpose of concrete selection strategy, no longer is repeated in this description at this.In actual applications, the formulation of concrete selection strategy is not limited only to above-mentioned several, and the variation of selection strategy does not influence protection scope of the present invention.
Step S605, conference management equipment notice is main enables this MCU as new spare MCU with MCU, mainly sets up periodic heartbeat message with MCU and new spare MCU and detects.
Concrete, conference management equipment can be enabled MCU as new spare MCU with MCU by the notification message notice is main.
By this step, realized spare MCU and main with the detection of the heartbeat message between the MCU, make the main protection that has regained spare MCU with MCU.
By the present invention, conference management equipment can be monitored the state of spare MCU in real time, and when spare MCU broke down, conference management equipment can be sought a suitable MCU automatically as spare MCU, guarantees that the master is in guard mode with MCU always.
