Embodiment
The present invention is further described in more detail below in conjunction with drawings and the specific embodiments.
In the 3G communication technology, NCP/CCP is the configuration of Radio Resource aspect, the transmission bearer link is the configuration of transfer resource aspect, and the transmission bandwidth that communication system will be distributed to Iub mouth NBAP signaling is planned to many transmission bearer links, and does the configuration of NCP, CCP when initialization.In the prior art, NCP or CCP and transmission bearer link are the fixing one-to-one relationships by configuration parameter binding, that is to say be assigned to certain concrete NCP, the message on the CCP can only be by initial configuration by certain pairing transmission bearer link transmit-receive of determining of NCP, CCP.And the method applied in the present invention, be in the process that the user inserts, according to the user's number among current each CCP, corresponding relation between configure user and the CCP, and at the transmission bearer link failure that the NCP correspondence takes place when (referring to that when NCP disposes two transmission bearer links of active and standby pattern active and standby transmission bearer link all breaks down), the common part information that will receive and dispatch on the NCP is adjusted on the CCP, by the pairing transmission bearer link transmit-receive of CCP, perhaps when the transmission bearer link occurs fault of CCP correspondence, user's specific messages on this CCP is adjusted on other CCP or the NCP, by other CCP or the pairing transmission bearer link transmit-receive of NCP, reach NCP, the dynamic assignment of the last message of CCP, the preferential simultaneously transmitting-receiving that guarantees common part information.
Because NCP, CCP be a kind of notion in logic, be exactly the fault of the transmission bearer link of NCP, CCP correspondence so NCP, CCP fault refer to.
If 4 of base station configuration transmission bearer links, configuration 1 of NCP, 3 of CCP, under all normal situation of NCP, CCP, the corresponding relation of NCP, CCP and transmission bearer link is as shown in Figure 1.Common part information is by the transmission bearer link transmit-receive of NCP correspondence, and user's specific messages is by the transmission bearer link transmit-receive of CCP correspondence.
Fig. 2 is NCP when breaking down, NCP, the CCP when common part information is tied to certain CCP and goes up and the corresponding relation figure of transmission bearer link.After the NCP fault,, then guarantee preferentially that according to bandwidth calculation common part information can use the pairing transmission bearer link of CCP to receive and dispatch as long as there is available CCP.The CCP that user's specific messages on common part information on the fault NCP or the fault CCP will be transferred to is available CCP.
Situation about breaking down for NCP, if determine to exist the utilized bandwidth of the remaining bandwidth of CCP greater than NCP according to bandwidth calculation, the common part information that the NCP that breaks down can be gone up transmitting-receiving is tied on the CCP of remaining bandwidth maximum, on CCP0, by transmission bearer link 1 transmitting-receiving of CCP0 correspondence; The common part information that also NCP that breaks down can be gone up transmitting-receiving is tied on the CCP of any one remaining bandwidth greater than the utilized bandwidth of NCP, and is unaffected with the signaling receiving and transmission that guarantees the base station.When subsequent user inserts,, will do the calculating of user's original allocation in conjunction with the shared bandwidth of NCP traffic load for the CCP that has bound common part information, as the sharing of load on the CCP0.So-called remaining bandwidth refers to the remaining bandwidth that is not taken by traffic load among a CCP or the NCP; Utilized bandwidth refers to the shared bandwidth of traffic load among a CCP or the NCP.Be directed to NCP, traffic load can refer to the common part information of receiving and dispatching and/or user's specific messages thereon; Be directed to CCP, traffic load can refer to the user's specific messages received and dispatched and/or common part information thereon.
Situation about breaking down for NCP, if there is the conflict of traffic load aspect in CCP, such as the remaining bandwidth that obtains any one CCP by bandwidth calculation all less than the utilized bandwidth of the NCP that breaks down, and the remaining bandwidth of all CCP is added up when being not less than the utilized bandwidth of the NCP that breaks down, can further the part or all of user's specific messages on the CCP of certain remaining bandwidth maximum be received and dispatched by the transmission bearer link of remaining CCP correspondence temporarily, then common part information be transferred on the transmission bearer link of this CCP correspondence and received and dispatched.As shown in Figure 3, NCP breaks down, the remaining bandwidth of any one CCP is all less than the utilized bandwidth of the NCP that breaks down, and the remaining bandwidth of all CCP is added up and is not less than the utilized bandwidth of the NCP that breaks down, and certain CCP, such as the remaining bandwidth maximum on the CCP0, then the part or all of user's specific messages on the CCP0 is transferred on the CCP of remaining user's specific messages that can hold on the CCP0 to be produced, on CCP1, promptly interim transmission bearer link 2 transmitting-receivings by the CCP1 correspondence, and the common part information on the NCP just can be transferred on the transmission bearer link of CCP0 correspondence and receives and dispatches.
When NCP breaks down, when if the remaining bandwidth of all CCP is added up also less than the utilized bandwidth of the NCP that breaks down, then can discharge part or all of user's specific messages of the CCP of remaining bandwidth maximum, just release portion or all user, to satisfy the bandwidth instructions for use of NCP, preferentially guarantee the transmitting-receiving of common part information.Discharging the user can realize by the user procedures that resets in the 3G communication system.When Fig. 4 is the NCP fault, NCP, the CCP when discharging user's specific messages and the corresponding relation figure of transmission bearer link, because the remaining bandwidth of CCP0, CCP1, three ports of CCP2 is added up also less than the utilized bandwidth of the NCP that breaks down, so release portion user specific messages, such as the user's specific messages on the CCP0, to satisfy the demand of holding the traffic load on the NCP.
Situation about breaking down for CCP, situation when processing method and NCP break down is similar, if determine to exist the utilized bandwidth of the remaining bandwidth of CCP, the user's specific messages on the CCP that breaks down can be tied on the CCP of remaining bandwidth maximum greater than fault CCP by bandwidth calculation; Also the user's specific messages on the CCP that breaks down can be tied on the CCP of any one remaining bandwidth greater than the utilized bandwidth of fault CCP.If there is the conflict of traffic load aspect in CCP, just the remaining bandwidth that obtains any one CCP by bandwidth calculation is all less than the utilized bandwidth of the CCP that breaks down, and the remaining bandwidth of all CCP is added up and is not less than the utilized bandwidth of the CCP that breaks down, then the part or all of user's specific messages on the CCP of certain remaining bandwidth maximum is received and dispatched by remaining CCP temporarily, and the CCP of the message on the fault CCP by aforementioned remaining bandwidth maximum received and dispatched; If the remaining bandwidth of all CCP is added up also less than the utilized bandwidth of fault CCP, and the remaining bandwidth of definite NCP then is tied to the user's specific messages on the CCP that breaks down on this NCP greater than the utilized bandwidth of fault CCP.If the remaining bandwidth of NCP is added up also less than the utilized bandwidth of fault CCP less than the remaining bandwidth of the utilized bandwidth of fault CCP and all CCP, then can preferentially directly discharge user's specific messages of fault CCP, to guarantee the common part information on the NCP and not have the original user's specific messages on the CCP of fault unaffected; Perhaps, discharge the user's specific messages on the CCP of remaining bandwidth maximum wherein, the user's specific messages with fault CCP uses the transmission bearer link of the CCP correspondence of this remaining bandwidth maximum to receive and dispatch then.
Situation about breaking down simultaneously for NCP, CCP, break down and the situation of CCP when breaking down handled in conjunction with NCP, just for the CCP fault of this moment, will not have NCP can attempt using, all the other processing and front are described similar, do not repeat them here.When if the remaining bandwidth of all CCP is added up also less than the utilized bandwidth of fault NCP and fault CCP, preferentially discharge part or all of user's specific messages of former fault CCP, unaffected with the original user's specific messages on the CCP that guarantees not have fault.
After NCP or CCP fault are eliminated, perhaps the transmission bearer link failure do not have to eliminate when but the traffic load on the CCP of all the other transferring user specific messages reduces, determine and whether have NCP and the shared transmission bearer link of CCP, or the shared transmission bearer link of a plurality of CCP, and there is the user to transfer to other CCP temporarily, according to NCP, the recovery situation of CCP transmission bearer link, recover original corresponding relation of common part information and NCP or user's specific messages and CCP, promptly according to the corresponding relation of common part information before the fault and NCP, common part information is used the pairing transmission bearer link transmit-receive of corresponding NCP; According to the corresponding relation of user's specific messages and CCP before the fault, user's specific messages uses the pairing transmission bearer link transmit-receive of corresponding CCP.Such as shown in Figure 5, after the NCP fault is eliminated, be that corresponding transmission bearer link 0 recovers normal use, then the user's specific messages that will transfer on the CCP1 from CCP0 under situation shown in Figure 3 shifts back the CCP0 transmitting-receiving, and original common part information is shifted back the NCP transmitting-receiving.
For realizing said method, the present invention also provides the processing unit behind a kind of communication port fault, comprises load control module and route selection module.
The load control module is used for the process in user's access, according to the user's number among current each CCP, corresponding relation between configure user and the CCP, and when the NCP fault takes place, according to bandwidth calculation is that common part information on the fault NCP is distributed CCP, perhaps when CCP breaks down, according to bandwidth calculation is that user's specific messages on the fault CCP distributes other CCP or NCP, to reach dynamic assignment, provide the configuration parameter of NCP or CCP simultaneously for route selection module to NCP, the last message of CCP.Described configuration parameter be used to describe on the NCP the common part information number and with the corresponding relation of NCP, or the user's specific messages number on the CCP and with the corresponding relation of CCP, and with some necessary transmission parameters such as corresponding relation of transmission bearer link.Concrete, the load control module can be calculated utilized bandwidth and the remaining bandwidth on NCP, the CCP, and offers route selection module, and upgrades the remaining bandwidth and the utilized bandwidth of preserving NCP, CCP.
