Step 302: this network equipment from docking with RNC light mouth, is switched to and reserves electricity mouth and land and be connected.Here, utilize data creating to change corresponding reservations electricity into from light mouth butt joint and mouthful land connection, detailed process is as follows:
Behind the electricity mouth of this convergence layer loop direction of correspondence of determining on the intersection equipment to reserve, on the network equipment, confirm the first low order time slot of the interconnection light mouth of this loop direction correspondence, then with the data deletion of NodeB circuit in the low order channel that breaks down on this network equipment on the corresponding network element of convergence layer, the interconnection of the interconnected second low order time slot of the first low order time slot and this loop and RNC light mouth deletion just, the last first low order time slot carries out interconnection with the reservation circuit port, finishes the switching of light mouth lower order Path to electricity mouthful lower order Path.
Step 303:, carry out the failure diagnosis of circuit according to the electricity mouth of reserving.
In the step 302 data connect complete and the no problem alarm after, the control system of central machine room can automatic generative circuit information and is finished prompting, just can carry out Fault Diagnosis and processing then, detailed process can be such:
Control system is carried out software setting to related network elements, generates the lower order transmission channel of transmitting-receiving from ring, and the 2G tester by docking with reservation electricity mouth just can carry out the judgement of associated disorders and confirm, and carry out the processing of obstacle.Here, can also utilize from encircling 2M line or loop stopper at reservation electricity mouthful DDF place, the tester by docking with reservation electricity mouth just can carry out the judgement of associated disorders and confirm then.The electricity mouth of 2G tester NodeB side can certainly be connected, carry out the judgement of associated disorders then and confirm, and carry out the processing of obstacle.
Step 304: after troubleshooting is intact, this network equipment is connected from landing with reservation electricity mouth, switches to RNC light mouth and dock.
Here, the first low order time slot and the path deletion of reserving circuit port, then the first low order time slot and the second low order time slot are carried out interconnection, the network equipment is landed connection from reserving electricity mouth, switch to RNC light mouth and dock, electricity is salty newly to place idle condition so that test next time thereby reserve.
In embodiments of the present invention, the used transport-type of TD-SCDMA network can be divided into following several model: (1) NodeB-transmission equipment-RNC machine room; (2) NodeB-transmission equipment-intersection equipment-RNC machine room.
Therefore, the network equipment described in the foregoing description can be the transmission equipment of model (1), also can be the intersection equipment in the model (2).Be example with the intersection equipment in the model (2) below, the embodiment of the invention is further described.
Before the obstacle diagnosis that carries out lower order transmission channel, need to reserve electricity mouthful, detailed process as shown in Figure 4:
Step 401:, on intersection equipment, reserve electricity mouthful according to the loop information of the low order channel of the TD-SCDMA network of preserving.
Obtain the loop information of the low order channel of TD-SCDMA network, search convergence layer loop correspondence under the NodeB, and what be connected with RNC light mouth intersects equipment, all reserve several 2M electricity mouths at this intersection equipment to each direction of convergence layer loop then, specifically can reserve several 2M electricity mouthful position in this DDF side of intersecting equipment.
Step 402: in the related data and network management data of low price passage,, write down and identify to the electricity mouthful position that reserves.
When 3G low order channel fault occurring, its obstacle diagnosis process of carrying out concrete lower order transmission channel is as follows, referring to Fig. 5.
Step 501:, determine the 2M electricity mouth that reserves according to low price passage related data and network management data.
When low order channel breaks down, information according to low price passage related data and network management data record, at first confirm the affiliated convergence layer loop information of NodeB in this low price passage, obtain this convergence layer loop correspondence then, and what be connected with RNC light mouth intersects equipment, last according to the sign of reserving electricity mouthful position, determine the 2M electricity mouth that reserves towards this convergence layer loop on this intersection equipment.
Step 502: should intersection equipment from docking with RNC light mouth, switch to and reserve 2M electricity mouth and land and be connected.Here, utilize data creating to change into landing with the 2M electricity mouth of corresponding reservation from light mouth butt joint and be connected, detailed process is as follows:
On intersection equipment, determine the 2M electricity mouth of this convergence layer loop direction of correspondence of reservation, just behind the low order test port of 2M tributary card, on the RNC Cross Connect equipment, confirm the first low order time slot of the interconnection light mouth of this loop direction correspondence; Then with the circuit deletion of this NodeB on the RNC Cross Connect equipment, just the first low order time slot and intersection equipment are docked the interconnection deletion of the second low order time slot of light mouth with RNC, the low order test port and the first low order time slot with the 2M tributary card carries out interconnection at last, form path, finish of the switching of TD light mouth lower order Path to electricity mouthful lower order Path.
Step 503:, carry out the failure diagnosis of circuit according to the electricity mouth of reserving.
In the step 502 data connect complete and the no problem alarm after, the control system of central machine room can automatic generative circuit information and is finished prompting, just can carry out Fault Diagnosis and processing then, detailed process can be such:
Control system is carried out software setting to related network elements, generates the lower order transmission channel of transmitting-receiving from ring, and the 2G tester by docking with reservation 2M electricity mouth just can carry out the judgement of associated disorders and confirm, and carry out the processing of obstacle.Here, can also utilize from encircling 2M line or loop stopper at reservation electricity mouthful DDF place, the tester by docking with reservation electricity mouth just can carry out the judgement of associated disorders and confirm.The electricity mouth of 2G tester NodeB side can certainly be connected, carry out the judgement of associated disorders then and confirm, and carry out the processing of obstacle.
Here, transmitting-receiving has comprised two electricity mouths on the lower order transmission channel of ring, thereby two test points are arranged, and like this, has improved and has utilized the 2G tester to carry out the accuracy of diagnosing fault of lower order transmission channel.
Step 504: after troubleshooting, will recover original light mouth circuit data, the 2M test port of reserving is placed idle condition again so that next diagnostic test for handling the 2M path data deletion that obstacle is made.
This shows, in the embodiment of the invention, only need do once and change intersection equipment, promptly be reserved with one or more electricity mouths at this intersection equipment, like this, when lower order transmission channel breaks down, just can utilize traditional 2G tester that the low order transmission channel is carried out failure diagnosis, thereby make full use of existing resource.And just can carry out failure diagnosis to lower order transmission channel at central machine room, saved the great amount of manpower capital like this.
