Abstract
When receiving call initiated by gateway GW belonging to opposite office gate keeper (GK), this office GK compares IP address of the GW with IP address configured by this GK so as to accomplish authentication for the call. When implementing intercommunication between a H.323 network and other multiple H323 networks under GK-GK H323 in repeat mode, the invention can authenticate call from GW under opposite office GK by this office GK to make call continuous. The invention also meets requirement that multiple gateways in same operation manager are corresponding to a relay cluster in this office, and also call ticket shows the operation mode.
Description
Technical field
The invention belongs to communication technical field, relate in particular under the relay networking mode H.323 technology calling authorization.
Background technology
Along with development of Communication Technique and the H.323 extensive employing of agreement in Softswitch technology, in the H.323 relay networking mode of agreement H.323 also being applied on the existing network more and more widely.
Mainly comprise following four kinds of patterns in the H.323 relay networking mode of agreement H.323:
1, peer-type relaying H.323, the type relaying are only applicable to local exchange and the opposite end office application scenario when being soft switch.
2, GW (GateWay gateway) type relaying H.323, the type relaying be applicable to soft switch as GK (GateKeeper gatekeeper) use, application scenario when opposite end office is GW in the same H.323 network.
3, GK type relaying H.323, the type relaying be applicable to soft switch as GK use, opposite end office is other GK in the same H.323 network or be other application scenario the during GK in the network H.323.
4, outside GK type relaying H.323, the type relaying are applicable to that soft switch uses as GW, the application scenario when opposite end office is outside GK.
Being used in combination of above-mentioned 4 kinds of relayings in existing network formed complicated H.323 network, also becomes more and more important based on the calling authorization technology of agreement H.323 in the Xiang Guan soft switch therewith.
In existing soft switch realizes, H.323 agreement to the method for authenticating that incoming call or local exchange make a call is: after the local exchange gatekeeper receives Setup (setting up call request) message, H.323, whether the IP address of at first judging the initiation end points that is comprised in (strategy 1) Setup message exists in the office direction table, seeing if there is the corresponding IP address and the corresponding relation of office direction, is incoming call if having then show; Otherwise (strategy 2) sends query messages to RAS (Registration, the agreement of using between Admission and Status end points and the gatekeeper) protocol process module, see whether be that local exchange makes a call, make a call if not local exchange, (strategy 3) judges whether to be registered to outside GK again and gone up, if be registered on the outside GK, then send ARQ (Admission Request call admission request) and give outside GK, carry out authentication by outside GK.If the three is not, think illegal calling, refuse this calling.
As mentioned above, after receiving Setup message, at first whether be incoming call by strategy 1 if can judge calling, if incoming call, can be again judges H.323 relaying or GK type relaying H.323 of peer-type according to relaying type identification position of institute's recorded information from Trk Group Data table, IP address; If the 1 pair of calling is carried out authentication and is judged and be not incoming call through strategy, whether can judge according to strategy 2 is that local exchange makes a call, herein can to the GW type H.323 the calling of relaying carry out authentication, because the GW type H.323 calling of relaying also need be registered earlier on GK before calling, there is log-on message the registration back in the RAS protocol process module, so to the GW type H.323 the judgement of junction call also handle in 2 at strategy, can distinguish GW type H.323 relaying or other callings of local exchange by the terminal type identification position in the log-on message; Whether if still can't carry out authentication to calling through strategy 1 and 2, just can judge by strategy 3 is H.323 relaying of outside GK type again, and the calling that still can't carry out authentication through these 3 strategies is rejected with regard to being considered to illegal the calling.
Under existing calling authorization method, when one H.323 network and other a plurality of H323 networks are with the intercommunication of GK-GK H323 trunking scheme, gateway under the GK that plays a game directly sends Setup message to local exchange GK, when the local exchange gatekeeper carries out calling authorization, because the IP address of this gateway is not in office direction table H.323, so can't carry out authentication by strategy 1; Because the gateway under the GK that plays a game is registered on the GK that plays a game, in the RAS of local exchange GK protocol process module, there is not log-on message again, so can't carry out authentication by strategy 2 yet; The gateway of on the GK that plays a game, having registered simultaneously, can not register to outside GK again, so strategy 3 is also unworkable, this has just caused local exchange GK can't realize the authentication from gateway call under the GK that plays a game, because can't authentication, certainly also just can't match trunk group and charge, can't satisfy trunk group of the corresponding local exchanges of a plurality of gateways of the same operator of playing a game, and the requirement that in ticket, embodies.
