The UMTS system has adopted and the similar structure of second generation mobile communication system, as shown in Figure 1, comprises RAN (Radio Access Network, wireless access network) and CN (Core Network, core net).Wherein RAN is used to handle all and wireless function associated, and CN handles that all voice calls are connected with data in the UMTS system, and the exchange of realization and external network and routing function.CN is from being divided into CS (Circuit Switched Domain in logic, circuit commutative field) and PS (Packet Switched Domain, packet-switched domain), CS generally comprises MSC (Mobile Switching Center, mobile switching centre)/VLR (Visitor Location Register, VLR Visitor Location Register), GMSC (Gateway Mobile SwitchingCenter, Gateway Mobile Switching Center), gsmSSF, PS generally comprises SGSN (Serving GPRSSupport Node, Serving GPRS Support Node), GGSN (Gateway GPRS Support Node, Gateway GPRS Support Node); CS mainly handles speech businesses such as relevant phone, voice, and PS then handles relevant Packet data service.UTRAN (UMTS Territorial Radio Access Network UMTS, land radio access web), CN and UE (User Equipment, user terminal) constituted whole UMTS system together, the UMTS system connects external network, for example: PSTN and the Internet.
Above-mentioned land radio access web UTRAN, its network configuration block diagram as shown in Figure 2, comprise at least one RNS (Radio Network Subsystem, RNS), a RNS is by a RNC (Radio Network Controller, radio network controller) and at least one NodeB (base station) form, NodeB can cover at least one sub-district CELL.
At present, UTRAN uses the Iu series interfaces, comprises Iu, Iur and Iub interface.
Interface between RNC and the CN is the Iu interface, and NodeB is connected by Iub interface with RNC, and the user terminal UE among NodeB and its sub-district CELL is by the Uu interface communication.The Iu interface section of the circuit commutative field CS of core net CN is called Iu_CS, and the Iu interface section of packet-switched domain PS is called Iu_PS.In UTRAN inside, interconnected by Iur between the RNC, Iur can connect or connect by transmission network by the direct physical between the RNC, and RNC is used for distributing and is attached thereto with control or the Radio Resource of relevant NodeB.NodeB then finishes the conversion of the data flow between Iub interface and the Uu interface, also participates in a part of RRM simultaneously, wherein:
NodeB is the base station (being radio receiving-transmitting unit) of WCDMA system, comprises radio receiving-transmitting unit and Base-Band Processing parts.By the Iub interface and the RNC interconnection of standard, mainly finish the processing of Uu interface physical layer protocol, major function is spread spectrum, modulation, chnnel coding and despreading, demodulation, channel-decoding, also comprises the functions such as mutual conversion of baseband signal and radiofrequency signal.
RNC is a radio network controller, is used to control the Radio Resource of UTRAN, mainly finishes functions such as connection foundation and disconnection, switching, the merging of grand diversity, RRM control.
The Iu interface is divided into Iu control plane and Iu user plane again, and the Iu control plane transmits signaling, and the Iu user plane transmits user data.ATM is adopted in the transmission of Iu interface, Iu adopts AAL2 (the ATM Adaptation Layer type 2 of ATM at user plane, AAL 2) adapting protocol carrying user face data, the professional main PVC (Permanent Virtual Circuit, permanent virtual circuit) of ATM that uses is as carrying.
Iub interface between RNC and NodeB generally uses a plurality of AAL2PVC to carry the data of UE, and these data comprise CS voice, the PS data of UE.
At present when the bandwidth of these AAL2PVC of configuration, need be every PVC reserved bandwidth, as on an E1, include only the AAL2PVC of carrying CS voice and the AAL2PVC of carrying PS data, if E1 physical interface total bandwidth is 2Mbps, the AAL2PVC bandwidth that then can dispose carrying CS voice is 1Mbps, and the AAL2PVC bandwidth of configuration carrying PS data is 1Mbps.Certainly, the AAL2PVC bandwidth that also can dispose carrying CS voice is the value less than physical interface total bandwidth 2Mbps, and the AAL2PVC bandwidth of configuration carrying PS data also be the value less than physical interface total bandwidth 2Mbps, but the AAL2PVC bandwidth that must satisfy carrying CS voice and the AAL2PVC bandwidth sum of carrying the PS data are smaller or equal to physical interface total bandwidth 2Mbps.
Above-mentioned prior art scheme, though can guarantee QOS (Quality Of Service well for every PVC reserved bandwidth, service quality), but under the limited condition of physical interface total bandwidth, the bandwidth of every PVC all can diminish, but the maximum utilized bandwidth of also promptly carrying certain class business can diminish, and the quantity that then directly causes such business to insert descends, and the interface utilance reduces.As working as the physical interface total bandwidth is 2Mbps, the AAL2PVC bandwidth of configuration carrying CS voice is 1Mbps, when the AAL2PVC bandwidth of configuration carrying PS data is 1Mbps, if there is not the CS speech business, and the PS data service needs the bandwidth of 1.5Mbps, the quantity that then just causes the PS data service to insert descends, but the physical interface total bandwidth has 2Mbps, and can not make full use of the physical interface total bandwidth, in addition, when having multiple pvcs, be under the situation of definite value then in the physical interface total bandwidth, the bandwidth of every PVC is just littler.
Therefore, because the physical interface total bandwidth is a definite value, when the configuration multiple pvcs, make all PVC sums equal the physical interface total bandwidth, the degree of freedom of each bar PVC bandwidth value of limitation arrangement greatly then during transfer of data, might can not make full use of the physical interface total bandwidth.

The maximum bandwidth that disposes each bar PVC when PVC band width configuration unit 341 equals E1 physical interface total bandwidth or is arbitrary value, and each bar PVC bandwidth sum is during greater than E1 physical interface total bandwidth, whether the PVC remaining bandwidth comparing unit 344 relatively new business desires remaining bandwidth that inserts PVC satisfies the required bandwidth of new business, with physical interface remaining bandwidth comparing unit 345 relatively the remaining bandwidth of E1 physical interfaces whether satisfy the sequencing of the required bandwidth of new business can be by control unit 347 controls.
In sum, the main technical schemes of the present invention's Bandwidth Management device is that every PVC that same physical interface is disposed includes the group management in, and the bandwidth that disposes every PVC is an arbitrary value, and each bar PVC bandwidth sum is greater than the physical interface total bandwidth, and the bandwidth sum that all kinds of business take during work is less than the physical interface total bandwidth; When new business inserts, as long as judge the remaining bandwidth of the required bandwidth of this new business smaller or equal to the PVC of its desire access, and also smaller or equal to the remaining bandwidth of described physical interface, PVC and the carrying of described physical interface that this new business is inserted by its desire.And, when the bandwidth of every PVC of configuration during all more than or equal to described physical interface total bandwidth, as long as judge the remaining bandwidth of the required bandwidth of new business smaller or equal to described physical interface, PVC and described this physical interface carrying that this new business is inserted by its desire.
The present invention also provides a kind of bandwidth management method of mobile communication system, and as shown in Figure 4, the workflow block diagram for preferable first execution mode of the bandwidth management method of a kind of mobile communication system of the present invention mainly comprises the steps:
But be the convenience of describing, below to equal the physical interface total bandwidth be the example explanation to dispose every PVC bandwidth.As shown in Figure 5, band width configuration figure for preferable first execution mode of the bandwidth management method of a kind of mobile communication system of the present invention, if certain IUB interface has only an E1 physical interface, this E1 physical interface disposes each one of RT/NRT PVC simultaneously, RT PVC carrying is used in CS speech businesses etc., so the required bandwidth of CS speech business is distributed on RT PVC; NRT PVC carrying is used in PS data services etc., so the required bandwidth of PS data service is distributed on NRT PVC.
Wherein, E1 physical interface total bandwidth=2Mbps, the bandwidth of configuration RT PVC and the bandwidth of NRT PVC are equal to E1 band width in physical total bandwidth, i.e. RT PVC bandwidth=NRT PVC bandwidth=2Mbps.
If there is the data flow of a CS audio data stream and PS data at present, and the bandwidth sum that the data flow of this CS audio data stream and these PS data takies is no more than E1 physical interface total bandwidth 2Mbps, as setting the 0.1Mbps that this CS audio data stream is just using RT PVC bandwidth, the data flow of these PS data is just being used the 1.1Mbps of NRT PVC bandwidth.
Step 402 need be when certain bar PVC inserts as new business, judges that the required bandwidth of this new business is whether smaller or equal to the remaining bandwidth of physical interface total bandwidth, if then insert this new business, otherwise refusal inserts this new business;
As shown in Figure 5, owing to there has been the data flow of a CS audio data stream and PS data, and this CS audio data stream has used the 0.1Mbps of RT PVC bandwidth, the data flow of these PS data has been used the 1.1Mbps of NRT PVC bandwidth, and then the remaining bandwidth of the remaining bandwidth of the remaining bandwidth of RT PVC, NRT PVC, E1 physical interface is respectively:
Remaining bandwidth=2Mbps-0.1Mbps=1.9Mbps of RT PVC;
Remaining bandwidth=2Mbps-1.1Mbps=0.9Mbps of NRT PVC;
Remaining bandwidth=the 2Mbps-0.1Mbps-1.1Mbps=0.8Mbps of E1 physical interface.
Be located in the process of data flow transmission of above-mentioned CS audio data stream and PS data, have a CS speech business to need to insert again, whether the bandwidth that then needs to judge these new CS speech business needs is smaller or equal to the remaining bandwidth 0.8Mbps of E1 physical interface.
If the required bandwidth of this new CS speech business smaller or equal to the remaining bandwidth 0.8Mbps of E1 physical interface, then inserts this new CS speech business, promptly RT PVC and E1 carry this new CS speech business;
If the required bandwidth of this new CS speech business is greater than the remaining bandwidth 0.8Mbps of E1 physical interface, then refusal inserts this new CS speech business.
As shown in Figure 5, after this new CS speech business is by RT PVC and E1 carrying, just upgrade the remaining bandwidth of this RT PVC, and upgrade the remaining bandwidth of E1 physical interface, then:
The required bandwidth of the new CS speech business of the remaining bandwidth=2Mbps-0.1Mbps-of RT PVC after the renewal;
The required bandwidth of the new CS speech business of the remaining bandwidth=2Mbps-0.1Mbps-1.1Mbps-of the E1 physical interface after the renewal.
When certain professional end of transmission, just carry out business and discharge, not only discharge the single PVC bandwidth that this business takies, discharge the physical interface total bandwidth that this business takies simultaneously.As shown in Figure 5, if new CS speech business end of transmission then discharges the RT PVC bandwidth that it takies, discharge the E1 physical interface total bandwidth that it takies simultaneously.
By above-mentioned process, can accomplish that every class business can farthest use the physical interface total bandwidth, guarantee that simultaneously all professional total bandwidths that insert do not exceed the physical interface total bandwidth.
Above-mentioned only is preferable first execution mode of the bandwidth management method of a kind of mobile communication system of the present invention, the band width configuration that the present invention does not limit every PVC of same physical interface arrives more than or equal to the physical interface total bandwidth, and it is only shared by 2 PVC not limit each physical interface total bandwidth.The present invention further can be at least two PVC to same physical interface, disposes every PVC maximum bandwidth and equals the physical interface total bandwidth, or be configured to arbitrary value as required: the bandwidth that disposes every PVC is all more than or equal to affiliated physical interface total bandwidth; The maximum bandwidth that disposes every PVC equals affiliated physical interface total bandwidth; The maximum bandwidth of configuration section PVC equals affiliated physical interface total bandwidth; The bandwidth of configuration section PVC is greater than affiliated physical interface total bandwidth.No matter but how to dispose, the bandwidth sum of all PVC must be greater than common physical interface total bandwidth, as described in preferable second execution mode of the bandwidth management method of a kind of mobile communication system of the present invention.
As shown in Figure 6, the band width configuration figure for preferable second execution mode of the bandwidth management method of a kind of mobile communication system of the present invention establishes certain IUB interface and has only an E1, and three PVC of this E1 configuration: a PVC, the 2nd PVC, the 3rd PVC.
PVC carrying is used in the CS speech business, so the required bandwidth of CS speech business is distributed on a PVC; The 2nd PVC carrying is used in the PS data service, so the required bandwidth of PS data service is distributed on the 2nd PVC; Broadcast/multi broadcast business uses the 3rd PVC carrying, so the required bandwidth of broadcast/multi broadcast business is distributed on the 3rd PVC.
The preferable second execution mode workflow block diagram of the bandwidth management method of a kind of mobile communication system of the present invention as shown in Figure 7, key step is as described below:
Disposing every PVC bandwidth is arbitrary value, the bandwidth that then can dispose every PVC is all greater than the physical interface total bandwidth, also can dispose all less than the physical interface total bandwidth, the maximum bandwidth that also can dispose every PVC equals the physical interface total bandwidth, the bandwidth that also can dispose whole PVC or part PVC greater than, equal, less than the physical interface total bandwidth, or the like various arbitrary values, no matter but how to dispose, the bandwidth sum of all PVC must be greater than the physical interface total bandwidth.
Describe easily but be clearer, below to equal the physical interface total bandwidth with the maximum bandwidth that disposes every PVC be that example describes.
As shown in Figure 6, E1 physical interface total bandwidth=2Mbps, dispose a PVC bandwidth, the 2nd PVC bandwidth, the 3rd PVC bandwidth and be respectively:
The one PVC bandwidth=E1 physical interface total bandwidth=2Mbps;
The 2nd PVC bandwidth=E1 physical interface total bandwidth=2Mbps;
The 3rd PVC bandwidth=0.5Mbps.
The one PVC bandwidth, the 2nd PVC bandwidth, the 3rd PVC bandwidth sum are 4.5Mbps, greater than E1 physical interface total bandwidth 2Mbps.
If have a CS speech business, a PS data service and a broadcasting/packet service at present, and the shared bandwidth sum of this CS speech business, PS data service and broadcasting/packet service is no more than E1 physical interface total bandwidth 2Mbps, the CS speech business is just taking the 0.1Mbps of a PVC bandwidth as described, the 1.2Mbps of the 2nd PVC bandwidth is just being used in described PS data service, and described broadcasting/packet service is just taking the 0.2Mbps of the 3rd PVC bandwidth.
As shown in Figure 6, owing to had a CS speech business, a PS data service and a broadcasting/packet service, and the 0.1Mbps of a PVC bandwidth has been used in this CS speech business, the 1.2Mbps of the 2nd PVC bandwidth has been used in this PS data service, this broadcasting/packet service has used the 0.2Mbps of the 3rd PVC bandwidth, and then the remaining bandwidth of the remaining bandwidth of the remaining bandwidth of the remaining bandwidth of a PVC, the 2nd PVC, the 3rd PVC, E1 physical interface is respectively:
Remaining bandwidth=2Mbps-0.1Mbps=1.9Mbps of the one PVC;
Remaining bandwidth=2Mbps-1.2Mbps=0.8Mbps of the 2nd PVC;
Remaining bandwidth=0.5Mbps-0.2Mbps=0.3Mbps of the 3rd PVC;
Remaining bandwidth=the 2Mbps-0.1Mbps-1.2Mbps-0.2Mbps=0.5Mbps of E1 physical interface.
In the transmission course of above-mentioned CS speech business, PS data service and broadcasting/packet service, there is a new CS speech business to insert again from a PVC, then the main deterministic process of this new CS speech business access can be as shown in Figure 8.
As shown in Figure 8, the judgement FB(flow block) for described new CS speech business inserts mainly comprises the steps:
Step 801 judges whether the remaining bandwidth of the PVC that desire inserts is enough, if enough, enters step 802; Otherwise, enter step 804;
As shown in Figure 6, above-mentioned new CS speech business desire inserts from a PVC, then:
Judge bandwidth that this new CS speech business needs whether smaller or equal to the remaining bandwidth 1.9Mbps of a PVC, if bandwidth that should new CS speech business needs then enters step 802 smaller or equal to the remaining bandwidth 1.9Mbps of a PVC; If the bandwidth that this new CS speech business needs then enters step 804 greater than the remaining bandwidth 1.9Mbps of a PVC, refusal inserts.
Step 802 judges whether the remaining bandwidth of physical interface is enough, if enough, enters step 803; Otherwise, enter step 804;
Judge bandwidth that this new CS speech business needs whether smaller or equal to the remaining bandwidth 0.5Mbps of E1 physical interface, if bandwidth that should new CS speech business needs then enters step 803 smaller or equal to the remaining bandwidth 0.5Mbps of E1 physical interface; If the bandwidth that this new CS speech business needs then enters step 804 greater than the remaining bandwidth 0.5Mbps of E1 physical interface, refusal inserts.
Step 803, access service;
The one PVC and E1 carry described new CS speech business.
Step 804, the refusal access service.
Step 703 after the PVC that new business inserts from desire inserts, is upgraded this PVC remaining bandwidth, and is upgraded the remaining bandwidth of E1 physical interface;
As shown in Figure 6, after this new CS speech business is by a PVC and E1 carrying, just upgrade the remaining bandwidth of a PVC, and upgrade the remaining bandwidth of E1 physical interface, the remaining bandwidth after then upgrading is respectively:
The required bandwidth of the new CS speech business of the remaining bandwidth=2Mbps-0.1Mbps-of a PVC after the renewal;
The required bandwidth of the new CS speech business of the remaining bandwidth=2Mbps-0.1Mbps-1.2Mbps-0.2Mbps-of the E1 physical interface after the renewal.
Step 704 in the data transmission procedure, behind certain professional end of transmission, is carried out business and is discharged, and not only discharges the PVC bandwidth that it takies, and also discharges the physical interface total bandwidth that it takies.
As shown in Figure 6, if new CS speech business end of transmission then discharges the PVC bandwidth that it takies, also discharge the E1 physical interface total bandwidth that it takies.
By above-mentioned process, can accomplish to improve the degree of freedom of every PVC bandwidth of configuration, and then as required, every class business can farthest be used the physical interface total bandwidth, guarantee that simultaneously all professional total bandwidths that insert do not exceed the physical interface total bandwidth.
In above-mentioned preferable second execution mode, only describe and judge the remaining bandwidth of the required bandwidth of new business earlier smaller or equal to the PVC of its desire access, and judge the order of the required bandwidth of new business again, this new business process that just can insert then smaller or equal to the remaining bandwidth of physical interface.In fact, bandwidth management method of the present invention also comprises the execution mode of the deterministic process of multiple order, as:
The deterministic process that wherein a kind of new business inserts is: judge earlier that the required bandwidth of new business is whether smaller or equal to the remaining bandwidth of physical interface, if, judge the remaining bandwidth of the PVC whether required bandwidth of new business inserts smaller or equal to its desire again according to this judged result, if then this new business just can insert; Above-mentioned two deterministic processes are as long as one is the result who negates, and this new business just can not insert.
The deterministic process that another kind of new business inserts is: judge the required bandwidth of new business whether smaller or equal to the remaining bandwidth of physical interface, and produce first object information; Also judge the remaining bandwidth of the PVC whether required bandwidth of new business inserts smaller or equal to its desire, also produce second object information.These two deterministic processes do not have mutual ordinal relation, and when this first object information and second object information are when sure, then this new business just can insert; When at least one was NACK messages when first object information and second object information, refusal inserted this new business.
The deterministic process that another kind of again new business inserts is: a control unit can be set, then the configuration result of each bar PVC bandwidth of same physical interface be passed to this control unit; This control unit is controlled the described remaining bandwidth of judging physical interface according to each bar PVC band width configuration result and whether is satisfied the required bandwidth of this new business and describedly judge whether the remaining bandwidth of the PVC that new business need insert satisfies the judgement sequencing of the required bandwidth of this new business.
When the configuration every PVC bandwidth all more than or equal to the physical interface total bandwidth, then this control unit deterministic process of making the described remaining bandwidth of judging the PVC that new business need insert whether satisfy the required bandwidth of this new business produces definite information always, and the deterministic process that only makes the described remaining bandwidth of judging physical interface whether satisfy the required bandwidth of this new business is carried out.When the bandwidth of every PVC of configuration is an arbitrary value, but all PVC bandwidth sums are during more than or equal to the physical interface total bandwidth, and control unit can be so that deterministic process adopts above-mentioned any one deterministic process.
In sum, a kind of bandwidth management method of the present invention mainly is that every PVC that same physical interface is disposed includes the group management in, and to dispose every PVC bandwidth be arbitrary value, and each bar PVC bandwidth sum is greater than the physical interface total bandwidth, and the bandwidth sum that all kinds of business take during work is less than the physical interface total bandwidth; When new business inserts, as long as judge the remaining bandwidth of the required bandwidth of this new business smaller or equal to the PVC of its desire access, and also smaller or equal to the remaining bandwidth of this physical interface, PVC and the carrying of described physical interface that this new business is inserted by its desire.And, when the bandwidth of every PVC of configuration during,, this new business is carried by PVC and described this physical interface that its desire inserts as long as judge the remaining bandwidth of the required bandwidth of new business smaller or equal to this physical interface all more than or equal to the physical interface total bandwidth.
