Abstract
The invention discloses an examination and verification method for a relay state, which includes the following steps: 1) when a processor board in a media gateway controller is started up, the media gateway controller sends a command of examination and verification of the relay state to all the media gateways and requests to examine and verify all the wildcards that belong to the processing board; 2) all the media gateways report the circuit status of all the wildcards of the step 1) to the media gateway controller; 3) the media gateway controller sets the circuit status of all the wildcards according to the circuit status reported by the step 2). The invention achieves the consistency between the media gateway controller and the circuit status of the media gateway, thus solving the problem concerning the inconsistency of replay states in special situations when large-capacity gateways access the media gateway controller.
Description
Technical field
The present invention relates to next generation network (NGN), relate in particular to a kind of relay state checking method.
Background technology
In the next generation network (NGN), be that Media Gateway Controller and MG are media gateway, utilize the characteristics of IP/ATM transmission network, can realize on the one hand the mutual of voice, image, data by traditional switch being separated into MGC; On the other hand, MGC can be more more easily introduces professionally, and MGC can be public telecommunication switching network, PLMN network interworking by MG and traditional PSTN also.
In next generation network, H.248, mainly finish: 1) under MGC control, finish the foundation and the release of the media channel among the MG as the main media gateway protocols between MGC and the MG; 2) under MGC control, the media channel and being connected with removing of bearer path of finishing among the MG are connected; 3) under MGC control, finish the configuration among the MG to the attribute of media channel and bearer path; 4) in MG, finish the operation of MGC, comprise playback, audit etc. media channel and bearer path; 5) event among the MG is reported MGC; 6) realize some simple call signalings, as analog line signaling, channel associated signalling etc.As can be seen, H.248 be a kind of control protocol up and down, MGC controls the behavior of MG fully.
Current great majority insert the MG of MGC, all less with the capacity of user or relaying, so on it the user that is with all be distributed on the same veneer in the MGC side.But continuous development along with intelligentized pstn, MGC need insert big capacity MG now, big capacity gateway may have tens0000, even the user of hundreds of thousands or relaying, all be distributed on the veneer obviously that capacity and disposal ability are unallowed to these users, this just need on the same gateway with user or relaying be distributed on the different veneers and share.
But will there be a problem like this, if a MGC wherein disposable plates has taken place unusually, as a certain veneer power-off restarting, or whole M GC is restarted, because big capacity MG is distributed on the polylith MGC disposable plates, the veneer that can't guarantee all big capacity gateways all starts up together, or the like situation, will cause the inconsistent of relay state.
Summary of the invention
Invention provides a kind of relay state checking method, can solve MGC and the inconsistent situation of MG relay state well.
The present invention includes following treatment step:
1) disposable plates in Media Gateway Controller starts, and Media Gateway Controller sends relay state audit order to each media gateway, and request is examined all wildcards that belong to this disposable plates;
2) each media gateway reports the circuit state of each wildcard of step 1) to Media Gateway Controller;
3) Media Gateway Controller is according to step 2) circuit state that reports carries out the setting of the circuit state of each wildcard.
Preferably, described step 2) specifically comprise following processing procedure:
21) if inner each the time slot circuit state unanimity of media gateway wildcard, then media gateway reports the signaling that has the side circuit state to Media Gateway Controller;
22) if inner each the time slot circuit state of media gateway wildcard is inconsistent, then media gateway reports inner each the time slot circuit state of this wildcard one by one.
Preferably, described wildcard is a time-division multiplexed frame E1.
Preferably, Media Gateway Controller is the AuditValue signaling to the relay state audit order that each media gateway sends in the described step 1); Described step 2) each media gateway reports circuit state by the AuditValue signaling to Media Gateway Controller in.
Preferably, media gateway sends the virtual condition of each time slot circuit when inner each time slot of wildcard is inconsistent, described step 2) to Media Gateway Controller by the SeviceChange signaling.
Adopt relay state auditing method of the present invention, MGC is by initiatively initiating the audit signaling, and then according to the correct status of the corresponding signaling acquisition cuicuit of MG feedback.If have the side circuit state in the response signaling, then correctly obtain the circuit state of whole wildcard; If inner each time slot circuit difference of wildcard, MG sends the virtual condition of each circuit more one by one by signaling, thereby realize the in full accord of MGC and MG circuit state, insert MGC, the inconsistent problem of some special circumstances relay state thereby solved big capacity gateway.
Description of drawings
Fig. 1 is a relay state auditing method flow chart of the present invention;
Fig. 2 is the schematic flow sheet of an embodiment of the inventive method.
Embodiment
The present invention is described in detail below in conjunction with accompanying drawing.
Fig. 1 is that method flow diagram is handled in relay state of the present invention audit, and what adopt in the flow process is agreement H.248, specifically may further comprise the steps:
Execution in step 103; If the E1 state is inconsistent, then execution in step 104;
In flow chart shown in Figure 2, the processing method of relay state audit of the present invention has been described, when because after a certain disposable plates of MGC starts successfully, or other abnormal cause, when a certain disposable plates of MGC started unusually, MGC initiatively initiated the relay state audit to all wildcards that belong to this disposable plates.If this wildcard internal circuit status unanimity, then MG replys correct state, and MGC is set to correct status according to the state of its return state corresponding circuits; And if this wildcard internal state is inconsistent, then MG is not with any state to return.If the wildcard internal state is inconsistent, MG reports each circuit state with ServiceChange more one by one.
Fig. 2 is the schematic flow sheet of an embodiment of the inventive method, comprises that step is as follows:
After a certain disposable plates starts among the step 201:MGC, MGC send this disposable plates to MG all belong to the AuditValue order of the relaying wildcard (the H.248 tidmask of agreement) of this MG, be with the meidia parameter, require audit all wildcards that belong to this disposable plates;
Step 202:MG reports circuit state according to the virtual condition of this wildcard (corresponding a certain time division multiplexing frame E1); If inner each the time slot circuit state unanimity of E1, then execution in step 203; If inner each the time slot circuit state of E1 is inconsistent, then execution in step 204;
Step 203:MG reports the AuditValue rpl signaling H.248 that has the side circuit state, and MGC is changed to corresponding state, execution in step 205 according to its virtual condition that reports with the circuit state management of correspondence.
Step 204, MG reports the AuditValue rpl signaling H.248 of not being with virtual condition, and MG reports inner each the time slot circuit state of this E1 one by one with signaling H.248ServiceChange;
Step 205, MGC manages the circuit state of correspondence according to its virtual condition that reports and is changed to corresponding state.
Above content be in conjunction with concrete preferred implementation to further describing that the present invention did, can not assert that concrete enforcement of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
