Summary of the invention
For defective and the deficiency that overcomes prior art, the object of the present invention is to provide a kind of method that gateway belongs to the switching home of control gateway of core control device that switches of can unifying as required to carry out.
In order to achieve the above object, the method for a kind of switching home of control gateway of core control device of the present invention may further comprise the steps:
(1) when needs switch the gateway ownership, the temporary transient interrupt response timer of the unified startup of one or more gateway that core control equipment switches at needs;
(2) core control equipment stops to respond the message that the gateway that needs to switch ownership reports in the time span that this timer sets, and the gateway that then needs to switch ownership belongs to switching to new core control equipment;
(3) behind this timer expiry, do not switch to new core control equipment if exist to need switch the gateway of ownership, then former core control appliance begins to respond to be needed to switch and not to switch to the information that the gateway of new core control equipment reports.
As a further improvement on the present invention, described temporary transient interrupt response timer is: the temporary transient interrupt response timer of the overall situation, the temporary transient interrupt response timer of classification or the temporary transient interrupt response timer of single gateway.
As a further improvement on the present invention, the method for the temporary transient interrupt response timer of startup described in the described step (1) is:
The entry condition or the employing manmachine command that set in advance according to system start temporary transient interrupt response timer.
As a further improvement on the present invention, the establishing method of time span is in the described step (2):
Determine the time span of temporary transient interrupt response timer according to the link detecting duration of agreement.
After adopting above-mentioned method, can start temporary transient interrupt response timer at the gateway unification that the needs ownership is switched, make core control equipment interrupt offering the service of gateway in during timer, impel these gateways to new home control facility registration, the gateway that can be simultaneously needs be belonged to switching carries out unified control and switches, simplify handoff procedure, and reduced the complexity of switching.
Description of drawings
Fig. 1 belongs to the structural representation of switching for the present invention;
Fig. 2 belongs to the flow chart of switching for the present invention.
Embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described in further detail.
As shown in Figure 1, core control equipment C1, core control equipment C2, core control equipment C3 are the core control equipments in the next generation network, are positioned at the key-course of the network architecture.
The inventive method can order one, a plurality of a, class or whole gateways to belong to switching, below respectively with two gateways, a class gateway and all the ownership of gateways switch and describe processing procedure of the present invention in detail:
(1) the main homing core equipment of MGCP gateway A 1 is core control equipment C1, and inferior homing core equipment is core control equipment C2.Behind the temporary transient interrupt response timer of having enabled on the nucleus equipment C1 at gateway A 1, before this timer expiry, nucleus equipment C1 is to the no longer responses of message from MGCP gateway A 1, but still respond message from other gateways, if gateway A 1 does not switch to core control equipment C2 behind this timer expiry, then former homing core control appliance C1 begins to respond the message that it reports, and above-mentioned employed timer-type is the temporary transient interrupt response timer of single gateway.
(2) H248 gateway B represents the H248 gateway cluster that core control equipment C1 is controlled, if enabled temporary transient interrupt response timer on the nucleus equipment C1 at the H248 agreement, then nucleus equipment C1 no longer responds all message from this H248 gateway cluster before this timer expiry, but still responds the message that the gateway from other protocol types reports.Such H248 gateway after finding that C1 does not have response, will initiatively switch to time core control equipment C3 of ownership, and above-mentioned employed timer-type is the temporary transient interrupt response timer of classification, can control 2 above equipment simultaneously.
(3) if core control equipment C1 has started the temporary transient interrupt response timer at the overall situation, then before this timer expiry, no longer respond the message that its all gateways of controlling report.Under the normal condition, MGCP gateway A 1 can switch on the core control equipment C2, and MGCP gateway A 2, H248 gateway and SIP gateway can switch on the C3.Behind the timer expiry, C1 begins once more the message that response gateway reports, and can re-register C1 if there is gateway to fail normally to switch this moment, and above-mentioned employed timer-type is the temporary transient interrupt response timer of the overall situation.
As shown in Figure 2, the idiographic flow of method of the present invention is:
(101) core control equipment is provided with the temporary transient interrupt response timer at one or more gateways as required, and the type of timer can be the temporary transient interrupt response timer of the overall situation, the temporary transient interrupt response timer of classification, the temporary transient interrupt response timer of single gateway;
(102) the gateway reporting message is given core control equipment;
(103) when a certain gateway ownership is switched, judge whether former core control appliance starts the timer at this gateway, if judged result then enters step (104) for not; If judged result is for being then to enter step (105);
(104) this core control equipment is handled reporting message, and step finishes;
(105) core control equipment stops to respond the message that the gateway that needs to switch ownership reports in the time span that this timer sets, and the gateway that then needs to switch ownership belongs to switching to new core control equipment;
(106) behind this timer expiry, do not switch to new core control equipment if exist to need switch the gateway of ownership, then former core control appliance begins to respond to be needed to switch and not to switch to the information that the gateway of new core control equipment reports.
Like this, can temporarily stop to respond timer according to unified startup of gateway of switching ownership at needs, make core control equipment interrupt offering the service of gateway in during timer, impel these gateways to new home control facility registration, control switching because can be simultaneously needs be carried out the gateway that the core net ownership switches, so simplified handoff procedure, and reduced the complexity of switching.
