Embodiment
The present invention is doing some improvement aspect the framework of existing total network signalling tracing system, mainly be between total network signalling tracing system and network element device, to increase the signaling tracing agent apparatus, this device can be deployed in (as shown in Figure 2) with network management system, also can dispose (as shown in Figure 4) separately.This device is mainly disposed in the assembly type mode, can close and can divide, and is flexible, thereby reduces the complexity of disposing.
As shown in Figure 2, comprise total network signalling tracing system, signaling tracing agent apparatus and network element device in the improved total network signalling tracing system that the present invention proposes.Adopt local area network (LAN) or private line access between signaling tracing agent apparatus and the network element device, between total network signalling tracing system and the signaling tracing agent apparatus, can adopt Internet connection, wherein:
Total network signalling tracing system is used for by signaling tracing agent apparatus and network element device alternately, initiates signaling tracing, and the indication network element device carries out signaling tracing, receives the signaling tracing data that network element device returns and shows;
The signaling tracing agent apparatus is used for communicating by letter just often with total network signalling tracing system, carries out route forwarding function, directly transmits information mutual between total network signalling tracing system and the network element device; And the total network signalling tracing system communication abnormality (such as shut down owing to reasons such as system maintenance or upgradings when total network signalling tracing system or unavailable or signaling tracing agent apparatus and total network signalling tracing system between network unusual) time; take over total network signalling tracing system; the indication network element device continues to carry out the signaling tracing task that total network signalling tracing system is initiated; carry out information interaction with network element device; and preserve the signaling tracing data that network element device returns; with the total network signalling tracing system communication recovery just often; give total network signalling tracing system with the signaling tracing transfer of data of being preserved; carry out route forwarding function, directly transmit information mutual between total network signalling tracing system and the network element device.Wherein, whether the signaling tracing agent apparatus communicates by letter normal by carrying out the link detecting judgement with total network signalling tracing system.
The signaling tracing agent apparatus further comprises: message transmitting module (Message Route Module, MRM) and the signaling data caching management module, MRM is connected by setting up Socket with CTS and network element device, realize the forwarding of two-way news, thereby realize the message between CTS and the network element device system, can cross over and carry out transparent transmission between the network segment, wherein:
Message transmitting module is used for communicating by letter just often with total network signalling tracing system, and the nonintervention net element communication only as routing function, carries out the forwarding of total network signalling tracing message, directly transmits the mutual information of total network signalling tracing system and network element device; With total network signalling tracing system communication abnormality (for example network is unusual or CTS unusual) time, intervene net element communication, the signaling tracing message that network element device sends is replied, make network element device think that the chain rupture situation does not appear in CTS, continue to keep reporting of signaling tracing data, message transmitting module also indication signaling metadata cache administration module receives and preserves the signaling tracing data that network element device returns; Whether message transmitting module communicates by letter normal by link being detected judgement with total network signalling tracing system.
The signaling data caching management module, be used for indication according to message transmitting module, receive the signaling tracing data that network element device sends, and save as the signaling tracing data file, recover just often at total network signalling tracing system, transmit described signaling tracing data file and give described total network signalling tracing system.
The signaling data caching management module is also filtered the signaling tracing data.When message transmitting module and network element device communication, have a large amount of interacting messages.The signaling data caching management module needs correctly to identify the signaling tracing message of reported by network element equipment, carries out the signaling tracing data that signaling tracing reports thereby accurately preserve network element device, and is not bothered by other redundancy message.Signaling tracing message is carried an event number, the signaling tracing message of same signaling tracing task is carried same event number, thereby can correctly identify the signaling tracing message of this signaling tracing task correspondence, thereby accurately preserve the signaling tracing data of this signaling tracing task.When the signaling tracing data are kept at the signaling tracing data file, can adopt binary system to preserve data, directly preserve complete message code stream, when the signaling tracing data file surpasses certain size, this document be compressed.
The present invention also proposes a kind of improved total network signalling tracing method, specifically comprises:
S1 creates the signaling tracing task in the total network signalling tracing system client, and initiates total network signalling tracing, sends the signaling tracing request to message transmitting module.
Be equivalent to create system-level signaling tracing task this moment on total network signalling tracing system, even at this moment close total network signalling tracing client or server, also do not influence the normal operation of this signaling tracing task.Unless on total network signalling tracing system, initiate to stop the request of this signaling tracing task.
S2, message transmitting module is transmitted this signaling tracing request to network element device, and network element device returns response message and gives total network signalling tracing system, begins to carry out signaling tracing, regularly or return signaling tracing message to message transmitting module when reaching certain data volume;
S3, message transmitting module is received and is carried out following processing after this signaling tracing message:
When total network signalling tracing system is communicated by letter normal situation with the signaling tracing agent apparatus under, message transmitting module is served as route transparent transmission function, direct pass-along message, promptly directly the signaling tracing forwards is given total network signalling tracing system, and total network signalling tracing system is transmitted to network element device to the response message of signaling tracing message;
When total network signalling tracing system and signaling tracing agent apparatus communication abnormality, specifically may be because total network signalling tracing system is safeguarded or the network failure or the unstable networks of upgrading or total network signalling tracing system server, cause link that reason interrupt runs such as problem are arranged, message transmitting module and network element device carry out interacting message, the signaling tracing message that network element device returns is replied, notice signaling metadata cache administration module carries out adapter work simultaneously, and the signaling tracing data of carrying in the signaling tracing message are carried out caching process.
When the signaling tracing agent apparatus is communicated by letter by abnormal restoring just often with total network signalling tracing system; the normal net element communication controlling links of recovery that message transmitting module is level and smooth; message is carried out routing forwarding; stop the signaling tracing metadata cache operation of signaling data caching management module; initiatively obtain the signaling tracing data of signaling data caching management module buffer memory by the total network signalling tracing server, perhaps directly the signaling tracing data are sent to total network signalling tracing system by the signaling data caching management module.Pass through FTP (file transfer protocol (FTP)) mode or SFTP (Secure File Transfer Protocol) mode command transmitting tracking data between total network signalling tracing system and the signaling data caching management module.
Further specify the present invention below by specific embodiment.
Step 110, the port open of signaling tracing agent apparatus and preparation.
No matter be to adopt the accompanying drawing 2 or the network device of accompanying drawing 4, the signaling tracing agent apparatus need be opened the port watcher thread respectively in corresponding ports after startup finishes.In CTS and MRM side, need monitor particular port.In MRM and network element device side, need know the IP address of network element device, the port of opening corresponding IP address is monitored and is connected with network element device.In the CTS system, need to determine the machine IP address at MRM place, and configure this IP address, make between CTS and the MRM and set up communication link.Like this, the link of whole system just is in normal condition.For the foundation of communication link, multiple implementation can be arranged for concrete CTS and MRM, finally be to guarantee that communication is normal between total network signalling tracing system (server) and signaling tracing agent apparatus and the network element device.MRM need start link test mechanism, the communication linkage situation between supervision and total network signalling tracing system, the network element device.
The schematic diagram that MRM communicates by letter with network element device is as shown in Figure 5:
Network element device is intercepted (as 6001 ports) at certain port, MRM initiates the request of connecting to this port, after the link establishment, network element device returns an event number message (as 1035 event number message) and gives MRM, MRM obtains syllable sequence from the 1035 event number message that network element device sends, Target id returns an event number message (as 1036 event number message) and gives network element device, so far, both sides connect successfully.Wherein, Target id is meant the ID that carries out the exchange of signaling tracing among the CTS, because may have a plurality of exchanges on the CTS, can carry out the signaling tracing of a plurality of exchanges.
Keep-alive process between MRM, CTS and the network element device:
When connecting between the two when initial. if connect and set up failure, program can be dished out one unusually, and think that link is unusual this moment.
Keep link activation to handle between CTS, MRM and network element device.Network element device sends a keep-alive message to MRM every a time interval (as 3 seconds); keep-alive message of every transmission; link detecting adds 1; MRM is transmitted to CTS with this keep-alive message; CTS returns a response message at this keep-alive message and gives MRM; MRM puts 0 with link detecting after receiving this response message, and this response message is transmitted to network element device.If having sent continuously, network element device (for example is no less than preassigned N; N is 5) keep-alive message, and do not receive the response message of MRM, can think network element device and MRM chain rupture; if MRM does not receive the response message of CTS, can think and the CTS chain rupture.In communication process, also carry out link detecting by the method for similar above-mentioned transmission keep-alive message.
Step 120, total network signalling tracing system is created the total network signalling tracing task.
Treat between total network signalling tracing system (server) and signaling tracing agent apparatus and the network element device communication all normally the operation after, the user opens the total network signalling tracing system client, login to the total network signalling tracing system server, behind signaling tracing conditional parameters such as client setting tracking entity, create the total network signalling tracing task.
Here following the tracks of the destination object on the network element device that entity is meant tracking, specifically may be agreement (as MM (Mobility Management mobility management protocol)), interface (as Mc, the interface between MSC Serve and the MGW)) or inside story.
On total network signalling tracing system client filter condition for the tracing message interface, show and follow the tracks of entity, allow the user choose and whether will follow the tracks of.
Tracing task is that an implementation of following the tracks of entity is followed the tracks of, and stops to follow the tracks of from beginning to trace into.The state of tracing task can be divided into four kinds of states:
NO ACTIVE: un-activation did not also start (as the timing tracing task, but timing also do not arrive, so tracing task is not activated) after the expression tracing task is created.
PENDING: start tracking message and send, wait acknowledge starts success message;
ACTIVE: state of activation illustrates current tracing task well afoot;
OVER: done state illustrates that tracing task stops.
Only when being in the ACTIVE state, tracing task just receives the signaling tracing data that report.Tracing task is set to the OVER state immediately when stopping to follow the tracks of, and also can not handle if receive the signaling tracing data again.
Step 130 begins to initiate the total network signalling tracing request.
Specifically comprise:
A) after the total network signalling tracing task creation finishes, manually to initiate the total network signalling tracing task or regularly initiate this signaling tracing task by total network signalling tracing system, total network signalling tracing system is initiated the signaling tracing request to MRM;
B) after MRM receives the signaling tracing request that total network signalling tracing system initiates, directly the signaling tracing request is sent on the network element device, as moving exchanging center MSC Server/ Gateway GPRS Support Node GGSN network element etc.;
C) after network element device is received the signaling tracing request, beam back and answer message to give MRM, MRM is receiveed the response this and is transmitted to CTS;
D) after CTS receives and receives the response, send out acknowledge message and give MRM, MRM transmits this acknowledge message again and gives network element device.Wherein, step (d) also can be omitted.
So far, this signaling tracing task is normally initiated success.Network element device begins to carry out signaling tracing to be handled, and passes through a series of logical process, signaling tracing message is returned sent to MRM.Carry the signaling tracing data in the signaling tracing message.Usually, network element device is reported signaling tracking message regularly, and/or the signaling tracing data that report report when reaching certain data volume.
Step 140, MRM receives the logical process after the signaling tracing message that network element device returns
MRM need handle according to the judgement of current link test mechanism after receiving the signaling tracing message that network element device returns, and is specific as follows:
Whether the link detecting mechanism between MRM and CTS and MRM and the network element device is to have the link of judging unusual when sending keep-alive message, if link is unusual, MRM transmission/reception keep-alive message is failed.The concrete method of judging is seen step 110, but the invention is not restricted to this, and other chain circuit detecting method also can be arranged.
If link test mechanism detects MRM and total network signalling tracing system (server) communication link is normal, then directly give total network signalling tracing system the signaling tracing forwards that receives, wherein, carry the signaling tracing data in the signaling tracing message, total network signalling tracing system is according to the signaling tracing data of returning, present corresponding results on client end interface, and return and give MRM to the response message of this signaling tracing message, MRM is transmitted to network element device.
If link test mechanism detects MRM and total network signalling tracing system (server) link is obstructed, MRM be responsible for and network element device between interacting message, make network element device think that network chain rupture or abnormal conditions do not appear in current total network signalling tracing system, thereby continue to keep reporting of signaling tracing data; MRM is notice signaling metadata cache administration module adapter work also, and the signaling tracing data are preserved.
When the signaling data caching management module is preserved the signaling tracing data, can preserve, as reach the 5M size and then write again in the another one file, so repeatedly according to certain condition.When a file write finish after, need compress processing, for example compress with ZIP mode or RAR mode so that when in the future CTS obtains, improve the efficient of Network Transmission.
Communication link between MRM and total network signalling tracing system (server) recovers just often, the work of the cancellation signaling data caching management module that MRM is level and smooth, re-execute route forwarding function, with the signaling tracing forwards of reported by network element equipment to total network signalling tracing system, the response message of total network signalling tracing system is transmitted to network element device, and signaling tracing is proceeded.
The signaling tracing data file of preserving for the signaling data caching management module, at MRM and CTS link-recovery just often, MRM notifies CTS, initiatively obtains signaling tracing data file on the MRM by CTS.Specifically can obtain, after the CTS server obtains the signaling tracing data file, carry out decompression, read the signaling tracing data in the signaling tracing data file then, present in the total network signalling tracing system client by FTP mode or SFTP mode.
Below by an improved signaling tracking method of application example explanation the present invention.MRM needs can start immediately with shaking hands of network element device mutual after the CTS chain rupture.As shown in Figure 6.
A) initial link circuit is set up and keep-alive:
CTS and network element device connect when initial, after the link establishment success, network element device sends total network signalling tracing handshake information (such as 1035 event number message) to MRM, and MRM obtained this 1035 event number message and preserved this moment, gave CTS this 1035 event number forwards simultaneously.CTS returns total network signalling tracing handshake response message (as 1036 event number message) and gives MRM, and MRM arrives network element device to this 1036 event number forwards again, and communication is normal between CTS, MRM and the network element device.During link idle, keep link activation (keep-alive) to handle between CTS, signaling tracing agent apparatus and the network element device afterwards.Wherein, event number is a sign, and above-mentioned 1035,1036 event numbers just are convenient to explanation, also can use other event numbers, and the present invention does not limit.
B) when the signaling tracing task, CTS initiates total network signalling tracing request (as 1037 event number message), 1037 event numbers are to should the signaling tracing task, promptly 1037 event numbers are signs of this signaling tracing task, and the follow-up message related with this signaling tracing task is all carried this sign (promptly carrying this event number).MRM obtains this 1037 event number and preserves, and gives network element device with this 1037 event number forwards, and expression begins to prepare to start the signaling tracing task.Network element device postbacks 1037 event number message and gives MRM, and MRM transmits this 1037 event number message and gives CTS.Network element device begins signaling tracing, and regularly or send signaling tracing message to MRM when reaching certain data volume, signaling tracing message is all carried the sign of this signaling tracing task, i.e. 1037 event numbers.The effect of sign is that message and other message of signaling tracing task are distinguished.
Event number is a sign, and the message relevant with this incident is all carried this event number.For example the signaling tracing task be designated 1037 event numbers the time, the message of this signaling tracing task is all carried this sign of 1037 event numbers, concrete message content is decision as required then, can carry the signaling tracing data in the 1037 event number message such as the network element device transmission, the 1037 event number message that CTS returns are then carried response message.
C) CTS communicates by letter just often with MRM, and MRM is transmitted to CTS with the 1037 event number message (signaling tracing message) that network element device sends, and the response message of CTS is transmitted to network element device;
When CTS and MRM chain rupture (when upgrading) as the CTS server maintenance, after MRM receives signaling tracing message, with the CTS that preserves---〉1037 event number message of network element device send to network element device, signaling tracing is proceeded, and the 1037 event number message that send to MRM for network element device directly abandon.MRM orders about the signaling data caching management module and starts working, and the signaling tracing data that network element device is beamed back are preserved processing.After preservation finishes, compress with ZIP mode or RAR mode.
D) (finish when CTS and MRM link-recovery as the CTS server maintenance, start), initiation is to the request of connecting of MRM, MRM will be saved network element device---the total network signalling tracing handshake information (as 1035 event number message) of MRM sends to CTS, the 1036 event number message of returning for CTS abandon, 1037 event number timed tasks of network element device (promptly stopping initiatively the signaling tracing message of network element device to be replied) are given in the timed sending that stops the MRM unlatching simultaneously, again transmit 1037 event number message of the CTS---〉network element device that CTS sends and the network element device that network element device sends---〉the 1037 event number message of CTS, promptly transmit the signaling tracing event message between CTS and the network element device again.
So far it is normal that the link maintenance of both sides' net element communication recovers.
Total network signalling tracing system after the improvement that the present invention proposes can be realized total network signalling tracing according to above-mentioned steps.Certainly, according to concrete implementation difference, total network signalling tracing system improves can be different, and realization can be made an amendment slightly and be got final product.
The improved total network signalling tracing system that the present invention proposes, when total network signalling tracing system is unavailable, the signaling tracing agent apparatus serves as the role of total network signalling tracing system, level and smooth adapter and net element communication link maintenance, make network element device think that current system is without any unusually, thereby total network signalling tracing (system keeps track task) is proceeded, can not ended current ongoing signaling tracing task, guarantee the continual operation of signaling tracing task normal reliable.When total network signalling tracing system recovers just often, the normal net element communication of the recovery that the signaling tracing agent apparatus is level and smooth, the adapter signaling tracing work that the total network signalling tracing system energy is level and smooth, make signaling tracing carry out for a long time, satisfy the uninterrupted signaling tracing of the whole network, thereby effectively solve the weak point that traditional total network signalling tracing system can not carry out signaling tracing for a long time, satisfy the demand of operator.
