Description

Method for detecting silent fault of mobile communication

Technical field

The present invention relates to a kind of noiseless method of conversing in the mobile communication of terminal that detects, comprise unidirectional, two-way noiseless, effect is similar to the widely used signaling instrument of communication field, but between the interface that can use equipment, more can be deep into the bosom of communication apparatus, detection is followed the tracks of in professional and communication.

Background technology

Use in the mobile communication equipment process people; it is unidirectional or two-way noiseless when regular meeting runs into conversation; this is because software, hardware fault or the defective of communication apparatus cause BSS (Base Station System base station sub-system) even equipment also faults such as noiseless can occur in normal course of operation.At present people are to the noiseless processing method that waits soft fault of part communicating terminal, and generally be signaling instrument trace analysis signaling or inquire about professional logical connection situation by the backstage, but powerless for the failure cause of deep layer more.

Summary of the invention

The technical problem to be solved in the present invention is in order to have overcome the shortcoming that system's soft fault is handled of the prior art, solve exist in the prior art to the noiseless problem that waits soft fault to detect in real time of communicating terminal, method for detecting silent fault in a kind of mobile communication has been proposed.Detect in real time fault such as noiseless in the mobile terminal calling process, the communication failure between the orientation and communication equipment fast, thus accelerated processing greatly to equipment fault, greatly improved the stability of equipment.

Method for detecting silent fault in a kind of mobile communication of the present invention comprises the steps:

One, business transmission all increase an agent apparatus on the equipment of process, agent apparatus uses the internal communication passage and the operation maintaining background communication of place equipment;

Two, check whether logic coincide, if misfit, can be defined as software fault, detects and finishes;

Three, according to logic, check whether hardware is normal, if undesired, can be defined as hardware fault, detect and finish;

Four, the back level from the business transmission begins to read code stream, push away forward successively, thereby noiseless fault point can be determined to cause in the place of finding code stream to lose.

After having adopted method of the present invention, unidirectional, two-way no voice phenomenon when having cleared away all that occur in the mobile communcations system real-time and making a phone call, and help has solved the communication abnormality situation that occurs in beginning or the maintenance process, on system failure location, play the important and pivotal role, the stability of equipment is risen to a new height, improved the maintainability of system greatly, the present invention not only can detect fault in logic, more can detect the hardware fault of equipment.

Embodiment

Be described in further detail below in conjunction with the enforcement of accompanying drawing technical scheme:

Know-why of the present invention is such, the phone of a connection in the up process of GSM mobile communication network transmission is, modulation, coding through BTS (Base Transceiver Station base station transceiver) are delivered to BSC (Base Station Controller base station controller), BSC delivers to MSC (Mobile Switch Center mobile switching centre) after being decoded as voice signal again, otherwise then descending; Solving noiseless is the fault that business code flow is lost in the transmission line of appointment, just must know the transmission course of code stream in each equipment, each veneer even each chip.In whole transmission course, the transmission of code stream has three kinds of modes: the conversion process of the transmission on circuit such as E1 purely, the transparent transmission that continues of passing through the chip that continues, process encoding and decoding process chip.

The transmission situation of a telephone service in system seen accompanying drawing 1, and Fig. 1 has represented professional whole transmission course in entire equipment, and wherein M represents the encoding and decoding process chip; N represents the chip that continues.

Wonder whether code stream is lost, only need to follow the tracks of and catch the transmission situation of code stream in these equipment.Though the signaling instrument can be observed the A mouth and the Abis mouth situation of GSM equipment, orient is BTS, BSC or the problem of MSC, but, further following the tracks of detection again is powerless substantially, if directly veneer, the chip of transmission course are directly followed the tracks of, then must find the place that code stream is lost, thereby find out the guilty culprit of equipment and handle.

Maximum characteristics of the present invention are to detect in real time, and do not influence the normal operation of equipment, even can not have influence on the user that other use this mobile device.

Fig. 2 has illustrated principle of the present invention, and operation maintaining background is by the agent apparatus communication in internal communication passage and the equipment, and the agent apparatus operation response is safeguarded the detection that the backstage sends, the order that continues, revises internal memory, and return is as a result safeguarded the backstage.

At the characteristics that detect principle and GSM internal communication, business transmission all increase an agent apparatus on the veneer of process, agent apparatus uses the internal communication passage of place equipment to come and the operation maintaining background communication, operation response is safeguarded the detect-message that send on the backstage, comprise detect veneer, whether chip operation normal, service link is removed, is rebuild, show and revise the internal memory of veneer, read business code flow etc., and the result is returned the backstage, its effect is equivalent to computer remote control.When not detecting, agent apparatus is left intact, so do not influence the operational efficiency of equipment.

Among Fig. 2, in base station sub-system BSS and moving exchanging center MSC equipment, be provided with agent apparatus separately, operation maintaining background is by the agent apparatus communication in internal communication passage and the equipment.

Fig. 3 is the flow chart of detection method of the present invention.

1. check earlier whether the logic of this transmission line coincide

After noiseless problem occurring, keep the current talking state, can find the logical transport route of this conversation process by operation maintaining background.Because the connection process of a phone: very complicated from the signaling process of asking to assign, and each assigning process either party accident appears, even the capital causes the allocation assignment success, and actual phone may be noiseless, the result of these appointments, whether database all has corresponding record to inquire about, so just can find logic easily and coincide;

2. if can't find the problem place from the corresponding relation of logic, logic will be corresponded to all concrete physical route, comprise E1 line, veneer, chip, coffret etc., by the agent apparatus that moves on the operation background access veneer, the node of inquiry code stream main several transfers in whole system, as the chip that continues, encoding and decoding process chip, whether judgement is normal corresponding to continuing of this service circuit, whether the encoding and decoding process chip is received code stream and is handled, so just can find the reason of most of fault.If after having got rid of these possibilities, can get rid of the soft fault on the software basically, see that because look into the situation of getting off all data map of allocation assignment are all coincide to physical device from above;

3. at this moment if there is the signaling instrument then can orient the roughly place that code stream is lost quickly, as BTS or BSC, because the signaling instrument can be from analyzing the code stream transmission situation on the transmission line as the Abis mouth.

But can not orient the roughly place that code stream is lost if there is the signaling instrument yet, chip all has the function of reading flow through the code stream of its each time slot because continue, by the agent apparatus on the single-board device, read the code stream of each professional variation that produces from the veneer chip that continues, certainly the code stream that changes might not all be normal business code flow, but if be the code stream of fixing on certain bar circuit of reading, this can conclude that code stream must be lost in the transmission prime somewhere, analogize forward successively, then must find any bar circuit, the problem which piece single-board device or even which chip block go out; But if read less than fixing code stream, the also circuit that can be routed to appointment by the ring certainly or the segmentation of segmentation, where out of joint cooperate the such equipment of code stream analysis instrument or talk-back finally to orient then.

Certainly the failure cause of finally finding may be a hardware fault, as a certain road of certain chip that the continues soft fault etc. that continues, also may be software defect such as assignment with not being inconsistent of actual allocated, or the problem of radiofrequency signal aspect, and the actual problem that occurs may be of all kinds, but by top method, perhaps follow the prescribed order, perhaps interosculate, can find out the problem the very crux and also be improved, this method can also be professional as solving, and solves the problem of communication aspect, particularly lack the pertinent instruments instrument, perhaps when the inoperative situation of instrument possibility when the scene.

When occurring making a phone call when noiseless, keep the current talking state, distribute indication and mobile phone busy channel situation, can find the logical transport route of this telephone service according to back-end data, whether see whether whole circuit mates, be exactly the channel that distributes as the mobile phone busy channel; If the whole piece road is all consistent, then be mapped on concrete physical circuit, veneer and the chip, whether read continuing of bottom by agent apparatus normal, and whether encoding and decoding are handled normal; If it is all out of question, can be from the back level of that noiseless circuit, read the code stream of this circuit from the chip that continues, push away forward successively, perhaps a side phone from ring (he can hear by word himself like this) or be routed on the circuit of appointment (as receiving on the similar equipment of talk-back), must find the unusual reason of code stream like this.

The method of the invention is similar to present computer remote control method, can directly visit the bottom of communication apparatus by operation maintaining background, for the problem that solves the non-lab environment in the practical application significant meaning is arranged, and do not influence the normal operation of whole system during operation.
