Embodiment
In order to make the purpose, technical solutions and advantages of the present invention clearer, below lift specific embodiment and, the present invention is further elaborated with reference to accompanying drawing.
The present invention only is provided with a fault location system, and each NGN equipment that is used for calling procedure is related to carries out fault location.The equipment that carries this fault location system is connected with NGN equipment, sends to NGN equipment to start fault location message, thereby makes NGN equipment follow the tracks of this calling procedure according to this message, and the NGN equipment that this calling procedure is related to carries out fault location.
Fig. 1 carries the equipment of fault location system and the network architecture schematic diagram between the NGN equipment for the present invention, as shown in the figure: the equipment of carrying fault location system is connected with NGN equipment respectively, as: being connected with Softswitch is connected with MRS is connected with IAD and is connected with access media gateway (AMG) and is connected with Universal Media Gateway etc.Between fault location system and the connected NGN equipment is mutual alternately: fault location system sends startup fault location message for the NGN equipment that relates to this calling procedure, the NGN equipment that receives this message is followed the tracks of this calling procedure, and tracking results is reported fault location system.
The process of positoning call fault can be divided into three phases: start the fault location stage, to the call phase of fault number and stop the fault location stage.Below detailed respectively this three phases of introducing.
(1) starts the fault location stage
At first, the Softswitch of fault location system in NGN sends and starts fault location message, and this message carries the task identification of this fault location of unique identification, fault number and Internet protocol (IP) address of fault location system and the port numbers of reception tracking results that this fault location is followed the tracks of.Wherein, task identification is by fault location system unified distribution and assurance uniqueness; NGN equipment is according to the IP address that starts the fault location system that fault location message carries and receive the port numbers foundation of tracking results and being connected of fault location system; When NGN equipment by set up report tracking results with being connected of fault location system to fault location system the time carry this task identification, fault location system determines according to this sign which inferior fault location task is the message that is reported belong to.
Secondly, Softswitch is preserved the information that this message is carried after receiving the message that starts fault location as a track record.Judge according to the fault number that this message is carried whether this fault number is the number of Softswitch management, if, judge that then this fault number is the intra-office number, determine the AG of this fault number and on AG corresponding port, send to this AG IP address that carries task identification, this fault number and fault location system and the Call failure localization message that receives the port numbers of tracking results; Otherwise, judge that then this fault number is a number not in the know, the gateway of this fault number is TG, the TG of Call failure number process process dynamically determines in calling procedure, so Softswitch does not carry out any operation.
At last, after AG receives the Call failure localization message of Softswitch transmission, the information that this message is carried is preserved as a track record, the IP address of the fault location system that carries according to this message and the port numbers that receives tracking results set up with fault location system between be connected.
(2) call phase of fault number
When AG is arrived in a call proceeding, the number that AG carries according to this calling judges whether and will follow the tracks of this calling, if, because AG has set up with the Call failure system and has been connected, then the AG relevant treatment information reproduction portion that will carry out this calling at AG reports fault location system as tracking results; Otherwise then AG is according to prior art this calling that continues.
When this call proceeding is to Softswitch, the number that Softswitch carries according to this calling judges whether and will follow the tracks of this calling, if, then will duplicate portion at the process information that Softswitch carries out this calling, report fault location system as tracking results, carried task identification in follow-up gateway and MRS transmission simultaneously to this calling process, follow the tracks of the IP address of start and stop sign and fault location system and the message related to calls of the port numbers that receives tracking results, to notify this gateway and MRS of calling out process to report tracking results to fault location system, this gateway comprises the AG of this calling, TG gateway and SG gateway etc., following the tracks of the start and stop sign is the current sign of whether following the tracks of of expression that sets in advance; Otherwise then Softswitch is according to prior art this calling that continues.
The gateway of this calling process and MRS receive and have carried task identification, after following the tracks of the message related to calls of the IP address of start and stop sign and fault location system and the port numbers that receives tracking results, judge whether to have set up to be connected with fault location system, if do not have, then the IP address of the fault location system that carries according to this calling and the port numbers that receives tracking results set up with being connected of fault location system after, the relevant treatment information reproduction portion that will carry out this calling at gateway and MRS, report fault location system as tracking results, simultaneously, for prevent with the fault location system connection procedure in information drop-out, gateway and MRS will be not in the process that connects with fault location system send to Softswitch receives the response, and temporary transient block to the processing of this calling up to set up being connected of fault location system finish after; Otherwise, will duplicate portion at the process information that gateway and MRS carry out this calling, report fault location system as tracking results.
(3) stop the fault location stage
After this calling procedure finished, this calling of gateway, MRS and Softswitch follow the tracks of to(for) the notice of Softswitch in calling procedure stopped to follow the tracks of automatically, disconnect the connection with fault location system.
When fault location system will stop this call follow process and this calling procedure and do not finish, can stop fault location message to what Softswitch sent the IP address of carrying task identification and fault location system.
After Softswitch received this message, at first the definite calling that will stop to follow the tracks of of task identification of carrying according to this message stopped this calling; Secondly, transmit this to the gateway of this callings process and MRS and stop fault location message, receive the definite calling that will stop to follow the tracks of of task identification that this gateway that stops fault location message and MRS carry according to this message, stop this calling.
When if Softswitch is transmitted this and is stopped fault location message, the NGN fault appears, AG does not receive this message, then AG also can stop the number that this calling: AG carries according to this calling by following manner and will follow the tracks of this calling with the identical judgement of fault number in the track record, but but do not receive the task identification that carried of Softswitch transmission, follow the tracks of the IP address of start and stop sign and fault location system and the calling of the port numbers that receives tracking results, then AG concludes that then this task is stopped on Softswitch, this call follow task on the AG is unusual existing of task, and AG stops to carry out this call follow task.
