Embodiment

Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, 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 belong to the scope of protection of the invention not making the every other embodiment that is obtained under the creative work prerequisite.

The management method of the media resource that the embodiment of the invention provides comprises:

When specific implementation, described asset management device can be MG-C, and described resource control appliance can be MG-User.In embodiments of the present invention, MG-C, MG-User are and the different entity of resource management control appliance MGC of the prior art, the function that resource management control appliance MGC finishes in the prior art is finished in MG-C and MG-User cooperation jointly, a MG-C can connect with a plurality of MG-User, and a MG-User also can connect with a plurality of MG-C.Wherein, MG-C mainly finishes the forwarding of signaling between the condition managing of MG and MG-User and the MG or message; MG-User mainly finishes the application and the release of the MG resource relevant with customer service, and has not had state and the resource management function of MG, and state and the resource management function of MG are carried out by MG-C.

For example shown in Figure 1, Fig. 1 is a kind of network architecture diagram that a kind of managing medium resource method of the embodiment of the invention is used, Fig. 1 just explanation realizes a kind of implementation of the embodiment of the invention, the embodiment of the invention does not limit its concrete form, concrete quantity as MG-C and MG-User can not be subjected to restricted number as shown in the figure, and the MG-C more than 2, the MG-User more than 1 are the scopes that the embodiment of the invention covers.The following embodiment of the present invention is that example describes with framework shown in Figure 1 all, is appreciated that the alternate manner of and equivalent variations similar with framework shown in Figure 1, all is the scope that the embodiment of the invention is protected.

In a kind of implementation of the inventive method embodiment, MG-C1, MG-C2 have identical sign with respect to MG, and MG-C1 and MG-C2 are responsible for the condition managing of MG, and described state can comprise registration, audit operation of MG etc.; Simultaneously, MG-C1 and MG-C2 are responsible for the signaling between MG and the MG-User or the transmission of message, be that signaling or the message that MG sends to MG-User can send to MG-User (as MG-User1, MG-User2, MG-User3) by MG-C1 or MG-C2, simultaneously, MG-User (as MG-User1, MG-User2, the MG-User3) signaling or the message that send to MG can send to MG by MG-C1 or MG-C2.

Need set up link between MG and the MG-C and be used to communicate by letter, for example, can set up H.248 link etc.; Simultaneously, the embodiment of the invention does not limit the link number of setting up between MG and the MG-C, promptly MG can and MG-C1 or MG-C2 between set up link more than 1 or 1, when specific implementation, can carry out different settings according to different situations.Because MG-C1, MG-C2 have identical sign with respect to MG, thus MG by and MG-C between the link set up, the signaling (as login request message) that condition managing is relevant sends to a MG-C; For example, MG by and MG-C1 between a link setting up login request message is sent to MG-C1, described MG-C1 not only will finish the registration of MG, also need the login request message of described MG is sent to other MG-C (being MG-C2 in the present embodiment), and also finish the registration of MG at other MG-C.

Said method embodiment links to each other with MG by a plurality of MG-C, and described a plurality of MG-C have identical sign with described MG relatively.Like this, from the angle of MG, MG only links to each other with " one " MG-C, and the MG perception is less than the existence of a plurality of MG-C nodes.When MG-C fault linking to each other with MG, can also handle the business of MG by other MG-C, guaranteed that MG goes up professional reliability.

In the another kind of implementation of the inventive method embodiment, MG-C3, MG-C4 have different signs with respect to MG, with reference to figure 9, Fig. 9 is for realizing the concrete application scenarios schematic diagram of another kind of implementation of the inventive method embodiment, equally, only to be MG-C3, MG-C4 have a kind of scene of different sign specific implementations with respect to MG to Fig. 9, and the number of MG-C can be different in different scenes with the number of MG-User.Equally, MG can and MG-C3 or MG-C4 between set up link more than 1 or 1, when specific implementation, can carry out different settings according to different situations.Because MG-C3, MG-C4 have different signs with respect to MG, thus MG by and MG-C between the link set up, the signaling (as login request message) that condition managing is relevant sends to MG-C; For example, MG by and MG-C3 between a link setting up login request message is sent to MG-C3, by and MG-C4 between a link setting up login request message is sent to MG-C4.MG needs to register on MG-C3 and MG-C4 respectively, can be to initiate registration to MG-C3 and MG-C4 simultaneously, also can be to initiate registration to MG-C3 and MG-C4 one by one.

The main distinction of above-mentioned two kinds of methods is: when MG-C1 and MG-C2 have like-identified with respect to MG, MG-C1 or MG-C2 are after receiving the status message of MG, except that self handles, also need described status message is sent to MG-C2, and when MG-C3 and MG-C4 have different identification with respect to MG, MG-C3 and MG-C4 receive the status message of MG respectively, described status message are not sent to other MG-C.Except above-mentioned difference, in embodiments of the present invention, the description about embodiment under MG-C1 and the MG-C2 scene all applicable under MG-C3 and the MG-C4 scene, repeats no more.

In the above-described embodiments, because MG connects at least one MG-C, be responsible for the condition managing of MG by described MG-C, so can improve the reliability of system.For example, in the prior art, when communication link breaks down between MG and MGC, MG can wait for the recovery of communication failure, if can not recover at the appointed time, MG will break away from this MGC automatically then register to new MGC (alternative MGC), can cause MG to go up the professional of foundation like this and all interrupt.And the technical scheme that provides by the embodiment of the invention, if part MG-C node failure just, MG will can not withdraw from service.For example, when the MG-C1 fault, just the link failure between MG and the MG-C1 does not influence link between MG and the MG-C2, and therefore, MG can be not influenced in the registration of MGC, and MG can not withdraw from service, and the business of setting up on MG can be not influenced yet.Certainly, after fault MG-C node recovers, can recover the communication with MG again, thereby recover service, improve system reliability.

Equally, in the prior art, MGC estimates can to register to new MGC (standby MGC) by active request MG self will fault the time; MG can carry out according to the MGC that defines in the MGC address and re-register operation.And the technical scheme that provides according to the embodiment of the invention, the MG-C node is estimated self will fault the time, need to judge whether this MG-C node is a last node that is connected with MG, be that MG-C judges whether to also have normal MG-C to link to each other with MG, if there is not normal MG-C to link to each other with MG, show that promptly this MG-C node is last node that links to each other with MG, then active request MG is to new MG-C registration, otherwise, can not ask MG to new MGC registration, but MG this node (MG-C1) withdraw from service information notify other MG-C that are connected with MG.For example, in the application scenarios shown in Figure 1, MG-C1 estimates self will fault the time, to judge at first whether other MG-C nodes that link to each other with MG are normal, if other MG-C nodes are fault all, active request MG is to new MG-C registration, otherwise, the MG-C1 node can not ask MG to new MGC registration, but MG this node (MG-C1) withdraw from service information notify other MG-C nodes that are connected with MG, as MG-C2, handle the MG related service by MG-C2, thereby guaranteed that MG goes up professional reliability.Certainly, will repeat the process that MG-C1 withdraws from service when MG-C2 will withdraw from service, not have other normal MG-C node if MG-C2 judges, active request MG is to new MGC registration again.The technical scheme that this method embodiment provides requires the connection status between MG-C node maintenance MG and other MG-C nodes.The method of described maintenance includes but not limited to: set up mutual informing mechanism between the MG-C node.

In the inventive method embodiment, the forwarding of signaling or message between also responsible MG-User of MG-C and the MG.When MG-User need send to MG signaling or message, can select to be connected normal MG-C (MG-C1 as shown in fig. 1 or MG-C2) and transmit with MG, for example MG-User has selected MG-C1 to send to MG and has set up carrying indication etc.Optionally, if a plurality of MG-C that link to each other with MG are connected normally, MG-User can the principle by load balancing selects the MG-C to MG transmitting signaling or message, described load balancing principle includes but not limited to: selection at random, polling, selection load minimum or according in advance static configuration proportionality principle or the like, the embodiment of the invention does not limit the mode of specific implementation load balancing.

In addition, when needs increase MG-User newly, only need to increase being connected between MG-User and the MG-C node, MG need not to change, and during as newly-increased MG-User4, only needs at MG-C1, increase the data of MG-User4 on the MG-C2 node, need not configuration data on MG, MG does not know to have increased newly MG-User4 yet, because MG-User4 uses the MG resource by the MG-C node.In actual networking, the number of MG is a lot of usually, and the MG-C node is relatively just few, thereby has simplified the O﹠M work of network.

Below with regard to the detailed introduction of the inventive method embodiment implementation under concrete application scenarios.

With reference to figure 2, Fig. 2 is the schematic flow sheet of the inventive method embodiment implementation when MG initiatively initiates to register, and flow chart shown in Figure 2 is that example describes with application scenarios shown in Figure 1, comprising:

Step 201:MG initiates register requirement;

Suppose that a link between MG selection and the MG-C1 sends register requirement, request message is sent to MG-C1.

Step 202:MG-C1 accepts registration, and gives MG re-injection volume success response message;

All MG-User that step 203:MG-C1 notice is connected, MG succeeds in registration at MG-C1, is in service state;

Other MG-C that step 204:MG-C1 connects to MG transmits the MG register requirement as MG-C2;

When specific implementation, the last information that will possess all MG-C of MG connection of MG-C.In the application scenarios as shown in Figure 1, need to possess the information of MG-C2 on the MG-C1;

MG-C1 is transmitted to other all MG-C with the register requirement of described MG, as MG-C1 with as described in the register requirement of MG be transmitted to MG-C2; Described MG-C1 includes but not limited to the method that other MG-C transmits: transmit (mode of broadcasting) simultaneously to other MG-C, or transmit one by one to other MG-C.

After step 205:MG-C2 receives the MG register requirement of MG-C1 forwarding, finish the MG registration, and return the response message that succeeds in registration to MG-C1;

When specific implementation, if MG-C1 does not receive the response message that MG-C2 succeeds in registration, can periodically send the login request message of MG to MG-C2, duration can be joined, and withdraws from service up to MG at MG-C1.

When specific implementation, also execution in step 204 not, but directly login request message is sent to MG-C2 by MG, be that MG sends to login request message MG-C1 and MG-C2 simultaneously, accordingly, in step 205, be that MG-C2 receives the registration of finishing MG after the register requirement of MG.

All MG-User that step 206:MG-C2 notice is connected, MG succeeds in registration at MG-C2, is in service state.

When specific implementation, the message that MG is succeeded in registration at MG-C2 by MG-C2 sends to MG-User1, MG-User2, MG-User3, notifies described MG-User1, MG-User2, MG-User3, and MG succeeds in registration at MG-C2, and is in service state.

When MG-C1 had different signs with MG-C2 with respect to MG, execution in step 206, initiated registration to all MG-C one by one or simultaneously by MG.

Because MG is in MG-C1 and the registered success of MG-C2, so therein during a MG-C fault, during as MG-C1, MG-C2 can finish the processing of MG related service, has guaranteed that MG goes up professional reliability.

With reference to figure 3, Fig. 3 is the schematic flow sheet of the inventive method embodiment implementation when MG-User initiation carrying is set up, in the present embodiment, suppose that MG-User is after calling out control foundation, select a MG-C to send carrying and set up indication to MG, same is that example describes its specific implementation with application scenarios shown in Figure 1, and described method comprises:

Step 301:MG-User links to each other with MG from all according to the principle of load balancing, selects a MG-C among the normal MG-C of state;

Be that MG-User need send the indication of setting up carrying to MG, need transmit by MG-C, owing to more than one of the MG-C that links to each other with MG, so MG-User need select a MG-C from a plurality of MG-C; Simultaneously, need to select normal MG-C, to guarantee professional normal process.The embodiment of the invention links to each other with MG by a plurality of MG-C just, and the relative MG of a plurality of MG-C has identical sign, make MG-User that more selection space be arranged when selecting MG-C, when a MG-C fault can not be worked, MG-User can also select other MG-C to carry out professional processing, thereby has guaranteed the reliability and stability of business on the media gateway.Described normal MG-C is meant can the normal process business, and is connected normal MG with MG-User, MG.

Simultaneously, MG-User selects the principle of MG-C can not be defined as the load balancing principle, so long as can select normal MG-C, the mode that guarantees the normal process of MG-User and MG business all is the scope of embodiment of the invention protection.

In the present embodiment, suppose that MG-User has selected MG-C1 to send first message.

Step 302:MG-User sends the carrying carry self nodal information to MG and sets up indication;

After first message (as signaling message) that MG-User sends to MG is transmitted to MG by MG-C, also need MG-C that the response message of MG is returned to corresponding M G-User; Simultaneously, MG-User is normally more than 1, so MG-C need know signaling or message that MG feeds back are to send to which MG-User.This just needs MG-User to carry self sign when down signaling or message, when MG-C transmits the response message of MG or other and MG-User related news, described message can be routed to correct MG-User.

MG-User carries the mode of self nodal information in sending to the message of MG, include but not limited to: the nodal information that carries MG-User in affairs ID or context ID.

For example, MG-User sends to MG and sets up among the affairs ID of the indication that carrying sets up and carry the MG-User self information, can specify some bit position in the Transaction ID in the Add.request message, to carry the nodal information of MG-User self.For example, the node identification of MG-User1 is 1, then can be numbered in Transaction ID: xxx0001xxx, and wherein, " x " represents can be " 0 " or " 1 " on this position; The node identification of MG-User 2 is 2, can be numbered in Transaction ID: xxx0010xxx; The node identification of MG-User 3 is 3, can be numbered in Transaction ID: xxx0011xxx.

Equally, also can carry the nodal information of MG-User in context ID, for example, in carrying foundation indication context Context information be arranged, MG-User can carry the nodal information of MG-User in the Context ID that distributes.For example, the node identification of MG-User 1 is 1, then is numbered in Context ID: xxx0001xxx; The node identification of MG-User 2 is 2, then is numbered in Context ID: xxx0010xxx; The node identification of MG-User 3 is 3, then is numbered in Context ID: xxx0011xxx.

Step 303:MG-C1 sets up indicator message to carrying and sends to MG;

MG-C1 receives after carrying that MG-User sends sets up Indication message, and this message is sent to MG.

Step 304:MG finishes carrying and sets up, and returns second message to MG-C1, the response message that returns as MG;

After step 305:MG-C1 receives the response message of MG, from described response message, obtain the MG-User nodal information, and described response message is sent to corresponding M G-User.

Because indication is set up in the carrying that MG receives is that MG-User sends, send by MGC-C1, the nodal information that carries MG-User self among the affairs ID that indicates is set up in described carrying, MG is in returning to the response message of MG-C1, also include MG-User self nodal information that carries among the described affairs ID, described MG-C1 is routed to corresponding M G-User according to the MG-User nodal information that carries among the MG-User affairs ID with described response message.

Need to prove, after carrying is set up, if MG-User at operations such as the modification of this carrying, deletion, audits, MG is to this operation response, MG-C can carry out route according to MG-User nodal information among the affairs ID.The MG-User state of certain context of auditing for example at MG, MG-User can send out an audit message to MG, the context ID that comprises affairs ID and audit in the message can comprise affairs ID in the audit response message of MG, and MG-C carries out route according to the MG-User nodal information among the affairs ID.If the audit operation that MG initiatively initiates, MG-C carries out route according to the MG-User nodal information among the Context ID; For example, the MG state of certain context of initiatively initiating to audit at MG-C, MG sends an audit message to MG-C, owing to be that MG initiatively initiates, MG-C can't determine the nodal information of MG-User according to affairs ID, but can from the context ID of audit, obtain the nodal information of MG-User, when setting up because context ID is distributed by MG-User.

One of ordinary skill in the art will appreciate that: all or part of step that realizes said method embodiment can be finished by the relevant hardware of program command, aforesaid program can be stored in the computer read/write memory medium, this program is carried out the step that comprises said method embodiment when carrying out; And aforesaid storage medium comprises: various media that can be program code stored such as ROM, RAM, magnetic disc or CD.
