Description
Technical field
The present invention relates to communication technique field, relate in particular to after the chain rupture of Iub mouth link and chain rupture recovers the method and system of reprocessing.
Background technology
Iub mouth link between Node B and the RNC comprises the high-rise and link bottom two parts of link, the method of the chain rupture of existing detection Iub mouth link, chain rupture recovery and corresponding subsequent treatment, be asynchronous transfer mode (ATM according to Iub interface, Asynchronous Transfer Mode) the signalling ATM adaptation layer in the agreement (SAAL, Signaling ATM Adaptation Layer) agreement detects the chain rupture situation and the link-recovery situation of the high-rise SAAL link of Iub mouth link.Specifically referring to shown in Figure 1, Fig. 1 is the method that detects the chain rupture of Iub mouth link, chain rupture recovery and corresponding subsequent treatment in the prior art, comprise base station (Node B) 101 among the figure, radio network controller (RNC, Radio Network Controller) 102 and wireless portion (the OMC-R of operation maintenance center, Operation and Maintenance-Radio part) 103, concrete steps are as follows:
Existing SAAL agreement comprises SCCOP agreement and SSCF-UNI agreement two parts, the agreement of SCCOP is Q2110, the agreement of SSCF-UNI is Q2130, in the Q2110 agreement, existing high-rise link chain rupture detection method is set forth, and about 22 seconds time of this detection method maximum demand just can be finished the detection of whole link chain rupture.
Step 202,203, Node B101 and RNC102 detect the chain rupture of Iub mouth link, send alarm respectively to OMC-R103.
Node B101 is after detecting the chain rupture of Iub mouth SAAL link, and its down going channel sends broadcasting as usual.RNC102 still will be kept in the adjacent cell list with Node B101 corresponding district after detecting the chain rupture of Iub mouth SAAL link, and concurrent terminal is to the measuring command of Node B101 corresponding district.
Step 204,205, Node B101 discharges the private resource of all wireless network layers and transport network layer, and RNC102 discharges all wireless network layers of corresponding Node B101 and the private resource of transport network layer.
In this step, RNC102 and Node B101 discharge inner promising user's assigned radio resource of institute and ATM transfer resource separately, if exist for the public resource that private subscribers is distributed this moment in RNC102 inside, then this part resource also needs to discharge, the sub-district public resource of RNC102 inside does not then need to discharge, and is auto-available when this part resource will remain into the SAAL link-recovery.
Step 206,207, RNC102 sends the SAAL_Begin signaling packet to Node B101, and Node B101 sends the SAAL_BGK signaling packet to RNC102 after receiving the SAAL_Begin signaling packet.
The purpose of this step is to determine whether RNC102 after the chain rupture fault is got rid of and the Iub mouth SAAL link between the Node B101 recover.If Node B101 receives RNC102 and sends the SAAL_Begin signaling packet, shows that the Iub mouth SAAL link of Node B101 side recovers; If RNC102 receives the SAAL_BGK signaling packet that Node B101 sends, show that then the Iub mouth SAAL link of RNC102 side recovers.
Because the Iub mouth SAAL link between Node B101 and the RNC102 comprises two parts: the sendaisle and the receive path of the Iub mouth SAAL link of NodeB101 side, the sendaisle and the receive path of the Iub mouth SAAL link of RNC102 side.Therefore, recover deterministic process for above-mentioned SAAL link chain rupture, as long as Node B101 receives RNC102 and sends the SAAL_Begin signaling packet, it is insecure that the Iub mouth SAAL link that just shows Node B101 side has recovered, because this process can only prove the receive path of the Iub mouth SAAL link of Node B101 side and recover, and can not prove that the sendaisle of the Iub mouth SAAL link of Node B101 side recovers.
Step 208,209, Node B101 and RNC102 detect Iub mouth SAAL link and recover, and send alarm respectively and remove to OMC-R103.
The method of the chain rupture of existing detection Iub mouth link, chain rupture recovery and corresponding subsequent treatment has following shortcoming:
Node B is after detecting the chain rupture of Iub mouth link, its down going channel sends broadcasting and descending pilot frequency time slot (DWPTS) as usual, cause the terminal in this Node B corresponding district to reside in this sub-district all the time, even adjacent Cell Broadcast CB power is enough strong, also can't make the terminal in this Node B corresponding district be linked into adjacent sub-district.
RNC is after detecting the chain rupture of Iub mouth link, still will be kept in the adjacent cell list with this Node B corresponding district, concurrent terminal is to the measuring command of this Node B corresponding district, therefore, in other terminal enters this Node B corresponding district, to send measurement report to this Node B according to the measuring command that RNC sends, require to switch to this Node B corresponding district.
To the overlong time that the chain rupture of Iub mouth link detects, existing high-rise about 22 seconds time of link chain rupture detection method maximum demand based on the SAAL agreement just can be finished the detection of whole link chain rupture.
In Iub mouth link chain rupture failover procedure, prior art receives that by Node B the SAAL_Begin signaling packet that RNC sends is insecure with regard to determining that whole link has recovered, because Node B receives the SAAL_Begin signaling packet that RNC sends and only illustrate that the receive path of the Iub mouth SAAL link of Node B side recovers, and can not guarantee that the sendaisle of the Iub mouth SAAL link of Node B side recovers.

Embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described.
The method that the chain rupture of Iub mouth link detects among the present invention is: existing according to SAAL protocol detection Iub mouth link chain rupture method basis on, increase by two kinds of new detection methods: E1 detection method and light mouth detection method.Present Iub mouth is generally set up physical connection by E1 or optical fiber and RNC, and for this reason, these two kinds of methods all belong to aforesaid link bottom chain rupture detection method.
The E1 detection method
The Iub mouth is set up physical connection by E1 and RNC, generally, several E1 lines is bound an Inverse Multiplexing over ATM (IMA, Inverse Multiplexing for ATM) group, and this IMA group is in order to the data and the signaling of carrying Iub mouth.When chain rupture appears in Iub mouth link bottom, the IMA group will detect this chain rupture in a few tens of milliseconds, report IMA group deexcitation alarm.
Light mouth detection method
The Iub mouth is set up physical connection by optical fiber and RNC, and when chain rupture appears in Iub mouth link bottom, light mouth chip will detect this chain rupture fault in a few tens of milliseconds, reports the alarm of light mouth.
The above-mentioned three kinds of detection methods of method synthesis that Iub mouth link chain rupture among the present invention detects detect simultaneously to the bottom and the high level of Iub mouth link.Adopt E1 detection method and light mouth detection method to detect for Iub mouth link bottom, thereby detect fast because the Iub mouth link chain rupture that the chain rupture of link bottom causes.Detect for the high-rise SAAL protocol detecting method of prior art that adopts of link.
In Iub mouth link chain rupture testing process,, further report the SAAL chain rupture to alarm then to OMC-R if the chain rupture of Iub mouth link bottom will report IMA group deexcitation alarm or the alarm of light mouth.If Iub mouth link bottom is in normal operating conditions, only be the chain rupture of Iub mouth link high level, will directly report the SAAL chain rupture to alarm to OMC-R.If in the chain rupture of Iub mouth link is as yet not between convalescence, both received to report IMA group deexcitation alarm or the alarm of light mouth, receive SAAL chain rupture alarm again, think that then the chain rupture of Iub mouth link appears at the link bottom, these three kinds of alarms are the alarm that same chain rupture fault causes.

Step 302 after Node B101 successfully receives the SAAL_Begin signaling packet, is set up Iub mouth SAAL link, and returns the SAAL_BGK signaling packet and give RNC102.
RNC102 determines that Iub mouth SAAL link is normal after receiving the SAAL_Begin signaling packet of Node B101 transmission.
After Node B101 successfully receives the SAAL_STAT signaling packet, determine that the sendaisle and the receive path of the Iub mouth SAAL link of Node B101 side recovered normal.
After RNC102 successfully receives the SAAL_STAT signaling packet, determine that the sendaisle and the receive path of the Iub mouth SAAL link of RNC102 side recovers.
Fig. 3 after for Iub mouth link chain rupture among the present invention processing method and the processing method schematic diagram behind the link-recovery.Comprise base station (Node B) 101 among the figure, radio network controller (RNC, Radio NetworkControl) 102 and wireless portion (the OMC-R of operation maintenance center, Operation and Maintenance-Radio part) 103, step 401 is to 406 being processing method after the chain rupture of Iub mouth link, step 407 is to 411 being processing method behind the Iub mouth link-recovery, and concrete steps are as follows:
Step 404, RNC102 discharges all wireless network layers of corresponding Node B101 and the private resource of transport network layer.
After the Iub mouth link chain rupture between Node B101 and the RNC102, miscellaneous service in the Node B101 corresponding district can't carry out, if Node B101 continues to send broadcasting, will cause terminal to think the sub-district of this sub-district by mistake for inserting, and in a single day terminal inserts this sub-district, can't carry out any operation.Therefore, after the Iub mouth link chain rupture between Node B101 and the RNC102, Node B101 interrupts the transmission of broadcasting, makes terminal can't measure the broadcast singal of Node B101 corresponding district, and then makes terminal can not produce misconnection to go into.
The method that Node B101 stops to send broadcasting has following three kinds:
After method one: OCM-R103 received Iub mouth link chain rupture alarm, OCM-R103 sent the sign that stops to send broadcasting to physical layer, after physical layer receives and judges this sign, the transmission amplitude and 0 of broadcast channel is multiplied each other, thus the transmission of going off the air.
Method two: OCM-R blocks and Node B101 corresponding district after receiving Iub mouth link chain rupture alarm, thus the transmission of going off the air.
Method three: OCM-R carries out the deexcitation radio frequency operation to Node B101 after receiving Iub mouth link chain rupture alarm, thus the transmission of going off the air.
RNC102 will can not send the measurement report of this sub-district to terminal, and then avoid the terminal mistake to switch to this sub-district.
Node B101 recovers to send the method for broadcasting following three kinds:
After method one: OCM-R103 received that Iub mouth link chain rupture alarm is removed, OCM-R103 sent the sign that recovers to send broadcasting to physical layer, after physical layer receives and judges this sign, the transmission amplitude and 1 of broadcast channel is multiplied each other, thus the transmission that recovery is broadcasted.
After method two: OCM-R103 receives that Iub mouth link chain rupture alarm is removed, remove to the obstruction of Node B101 corresponding district, thereby recover the transmission of broadcasting.
Method three: OCM-R103 activates radio frequency after receiving that Iub mouth link chain rupture alarm is removed again, thereby recovers the transmission of broadcasting.
RNC102 will send the measurement report of this sub-district again, thereby makes other terminal switch to this sub-district according to this measurement report after upgrading adjacent cell list to terminal.
Above-mentioned implementation step 406 and 410 is an optional step, and the technical staff can select it according to actual conditions.
The above only is preferred embodiment of the present invention, and is in order to restriction the present invention, within the spirit and principles in the present invention not all, any modification of being done, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
