Description
Technical field
The present invention relates to the processing method of signaling in a kind of communication network, particularly a kind of method of in communication network, avoiding the signaling endless loop.
Background technology
The signaling of the Signaling System 7(SS-7) that defines at present domestic, the international standard connects control two kinds of addressing systems, and wherein a kind of is exactly the global title addressing.The global title of entity is a uniquely identified in the network.At signalling point during according to the global title addressing with signaling connection control function, need carry out Global Title translation, find out the signaling office direction that message sends by Global Title translation, signalling route, signaling link, transmit on the signaling link that signaling is obtained in Global Title translation then, wherein generally comprise the basis of global title in this signaling as next stage signalling point Global Title translation.
When but problem is Global Title translation, find out signaling office direction and signalling route and signaling link that signaling sends, if signaling sends to the next stage signalling point, and the next stage signalling point is not a destination signaling point, then need carry out Global Title translation once more at this signalling point.If, in the Global Title translation of next stage signalling point, the signaling office direction that obtains, signalling route and signaling link will cause the signaling endless loop so to the upper level signalling point between two signalling points, and because avalanche effect causes that signaling link is congested.
Fig. 1 is the networking schematic diagram of existing signaling network, wherein A represents signalling point A, B represents Signalling Transfer Point B, C represents signalling point C, D represents the signalling system No.7 link, at present, as shown in Figure 1 networking situation is very general in the communication network, and the signaling endless loop that above-mentioned Global Title translation process causes also happens occasionally under this networking situation.As suppose that following condition sets up:
1, the global title of signalling point A is 460030900001000 among Fig. 1; The global title of signalling point C is 460030900002000.
2, do not have direct-connected signaling link between signalling point A and the C, transfer by Signalling Transfer Point B.
3, adopt signalling system No.7 between signalling point, addressing system is the global title addressing, carries out Global Title translation 3 exchanges.
4, at signalling point A global title 460030900002000 is translated Signalling Transfer Point B; Signalling Transfer Point B translates signalling point A with global title 46003090000.(Global Title translation only disposes 46003090000, and whole global titles of hint 460030900000000-460030900009999 use identical configuration).
Then in this case, if exist signalling point A, will between signalling point A and Signalling Transfer Point B, cause the signaling endless loop because of Global Title translation through the message that Signalling Transfer Point B sends to signalling point C.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of method that causes the signaling endless loop because of the global title addressing that solves in communication network, solve the problem that the Global Title translation mistake that exists in the prior art causes the signaling endless loop, ensure the normal operation of signaling network in the communication network.

Step 23 is brought into to signaling information in the future, carries out Global Title translation, to Global Title translation execution in step 24 as a result;
Step 24 is judged Global Title translation this signaling message destination local exchange whether as a result, if, execution in step 25, if not, execution in step 3;
Step 25 withdraws from the endless loop checking process, according to normal process flow processing signaling message.
Its above step 3 may further comprise the steps:
Step 31, Global Title translation obtain next stage purpose signaling office direction;
Step 32 judges whether this signaling office direction exists load sharing, if, execution in step 33, if not, execution in step 37;
Step 33 is chosen an office direction of not judging, execution in step 34 from the signaling office direction of load sharing;
Step 34 judges whether this signaling office direction has identical information with the next of record to the signaling office direction, if, execution in step 38, if not, execution in step 35;
Step 35, this signaling office direction is next different to signaling office direction information with record, judges whether that the office direction of load sharing is not judged in addition, if, return step 33, if not, execution in step 36;
Step 36, the office direction of all load sharings all judged, and do not have the signaling endless loop, handles this signaling message according to normal flow, execution in step 39;
There is not the signaling office direction of load sharing in step 37, judge this signaling office direction whether with record to the signaling office direction identical information is arranged, if, execution in step 38, if not, execution in step 36;
There is the signaling endless loop in step 38, and this message is carried out respective handling, abandons message, and alarms to Operation and Maintenance; Execution in step 39;
Step 39 is returned, and waits pending next bar signaling.
The present invention has following advantage and effect:
Adopt the method for the invention, compared with prior art, effectively avoided because the system resource waste that the data configuration error causes, and dissolved the crisis of the potential system that influences security of operation.Reach the effect of prevention and protection, improved the fail safe and the robustness of system.The present invention is applicable to mobile switching centre in the wireless network, short message service center, Signalling Transfer Point, VLR Visitor Location Register, attaching position register etc., and all have signaling capability; need carry out the network entity of global title addressing; be applicable to that also intelligent network etc. uses SCCP agreement in the Signaling System 7(SS-7) and use the network entity of global title addressing in Signalling exchange; can be directly used in the communication network each signalling point protects; also can be used for special testing instrument; check system hidden danger, market application foreground is wide.
