Be that the implementation method that example is safeguarded circuit operation of the present invention is elaborated to lead inspection by office direction below.
Set maintenance console office direction A is led inspection to the sampling circuit between the office direction B, promptly to each E1/T1, the circuit that the sampling extraction can carry out initiatively leading inspection carries out initiatively leading inspection.
Be set in and carry out active and lead when inspection, the circuit number that the restriction per second is led inspection simultaneously can not surpass 100 circuit, if office direction A to outnumber 100 of the sampling circuit between the office direction B, the circuit that then surpasses is led in the follow-up time and is examined processing.
Maintenance console issues to ISUP/TUP office direction A is led the control command of inspection to the circuit between the office direction B, and the relaying type option of setting in this control command is ISUP.
Maintenance console starts timer when issuing the prosecution system of leading order, the timing length of setting timer is 10 seconds, and maintenance console waits in the timing length of timer that ISUP/TUP returns leads the inspection result.
ISUP/TUP receives the control command of leading inspection, because the relaying type option in the control command is ISUP, so ISUP samples to the circuit that can lead inspection between the office direction B to office direction A, and utilizes CCR message that the circuit of sampling is led inspection one by one and handles.ISUP finishes the inspection of leading of all sampling circuits and handles, and circuit is led the inspection result returns to maintenance console.Circuit is led the inspection result can return to maintenance console in many ways, returns together as returning, all lead the inspection result one by one, and many circuit are led the inspection result and returned or the like together.
When maintenance console before timing length is the timer expiry in 10 seconds, what receive all circuit that need lead inspection leads the inspection result, maintenance console will be led the inspection result and be gathered, and show.When if maintenance console is the timer expiry in 10 seconds at timing length, what still do not receive all circuit fully leads the inspection result, then thinks and leads the failure of inspection attended operation, and maintenance console shows that directly leading inspection handles overtime information.
Because the time of implementation by the prosecution system of the leading order of office direction is longer, therefore, maintenance console can also issue the control command that stops to lead by office direction inspection to ISUP as required.
Maintenance console issues when stopping to lead the control command of inspection by office direction to ISUP, start another timer, the timing length of setting this timer is 10 seconds, and maintenance console is waited for ISUP returns lead the inspection result or stop to lead the successful information of inspection in the timing length of this timer.
ISUP/TUP receives the prosecution system of the leading order that stops by office direction, because the relaying type option in the control command is ISUP, so ISUP utilizes the ongoing inspection process of leading of REL message and RLC message halt circuit.If ISUP is before receiving the prosecution system of the leading order that stops by office direction, carried out the control command of leading inspection by office direction, and do not return as yet and lead the inspection result, then immediately to maintenance console return current finished lead the inspection object information, even the current inspection of leading of also not finishing any circuit, also to return an information, make maintenance console can know that ISUP has stopped circuit and led the inspection operation, prevent to lead in the maintenance console timer expiry of prosecution system order correspondence to maintenance console.
ISUP return to maintenance console lead the inspection object information after, ISUP stops to lead the inspection operation to ongoing circuit of leading inspection by office direction, stop wall scroll in the flow process that stops to lead the inspection operation and the attended operation control command and lead that to examine flow process identical, ISUP also no longer leads inspection to the circuit of not leading inspection as yet, and stops to lead the successful information of inspection according to office direction to the maintenance console loopback.
If ISUP receive stop to lead the control command of inspection operation by office direction before, carried out the control command of leading inspection by office direction, and the inspection of leading of having finished all circuit is handled, promptly do not had to lead the circuit of inspection operation, ISUP also needs to stop to lead the successful information of inspection by office direction to the maintenance console loopback.
When maintenance console before timer expiry, receive stopping that all return and lead the successful message of inspection, show to stop to lead the successful information of examining by office direction.If when timer expiry, maintenance console does not still receive and stops to lead the successful information of inspection by office direction, then directly shows the information that stops to lead the inspection operation overtime.
The implementation procedure of other attended operation and the above-mentioned implementation procedure of leading the inspection attended operation are based on identical, and just other attended operations cannot carry out sample process as leading inspection, and other attended operations can all carry out attended operation to each the bar circuit between the office direction.Be not described in detail at this.
The present invention also can lead inspection to circuit according to trunk group and safeguard or circuit reset or enquiry circuit state, it is the trunk group that maintenance console determines to carry out circuit maintenance operation, and carrying out the control command of attended operation to the circuit that maintenance entity issues trunk group, maintenance entity carries out attended operation according to the control command of its reception to the circuit of described trunk group.In the attended operation process, exist equally sample process, simultaneously carry out the circuit of attended operation restricted number, timer, stop processing procedures such as control command by the attended operation of trunk group, with above-mentioned to carry out the detailed process of circuit maintenance operation by office direction basic identical, be not described in detail at this.
Though described the present invention by embodiment, those of ordinary skills know, the present invention has many distortion and variation and do not break away from spirit of the present invention, and the claim of application documents of the present invention comprises these distortion and variation.
