Description
Technical field
The present invention relates to Code Division Multiple Access (CDMA) (CDMA) technical field, be meant a kind of method of the ABIS of distribution interface band width resource especially.
Background technology
In cdma system, the interface between base station controller (BSC) and the base transceiver station (BTS) is called the ABIS interface, and this ABIS interface can adopt the E1/T1 mode to transmit.In the CDMA1X system, the ABIS interface usually is multiplexed with asynchronous transfer mode (ATM), realizes being connected of BSC and BTS in Permanent Virtual Channel (PVC) mode.
Figure 1 shows that the schematic diagram of transmission content in the ABIS interface.The content of transmission comprises in the ABIS interface between BSC and the BTS: business and signaling.Wherein, comprise data service and speech business etc. again for business; Comprise for signaling: be used to transmit the signaling of paging channel flow process and access channel flow process etc., and operational administrative link (OML) signaling relevant with Operations, Administration and Maintenance.
Figure 2 shows that the logical construction schematic diagram of ABIS interface.Exist between BTS and BSC and call out relevant common channel, as paging channel (PCH, Paging Channel) and access channel (ACH, Access Channel) etc., and the dedicated channel relevant with business, as primary channel (FCH, Fundamental Channel), Supplemental Channel (SCH, Supplemental Channel) and Dedicated Control Channel (DCCH, Dedicated Control Channel) etc.Simultaneously, also there is the OML signaling channel that is used to transmit the Operation and Maintenance signaling between BTS and BSC.Above-mentioned and the bandwidth resources of calling out relevant common channel and relevant dedicated channel and the OML signaling channel of being correlated with Operation and Maintenance use the ABIS interface jointly with business.And the most of channel in the ABIS interface is visible to mobile terminal (MS) and BSC only, and is sightless for BTS.
At present, management is not done to the resource in the ABIS interface usually by system, does not think that promptly the ABIS interface bandwidth is a resource.Whatsoever professional resource of applying for the ABIS interface, system all will be its unconditional distribution, therefore, the phenomenon of non-answered call or call drop often occur.
In the prior art, even the resource in the ABIS interface is managed, also only be simply the resource of every PVC in the ABIS interface to be averaged division, and think every kind of speech channel, no matter be speech business speech channel or data service speech channel, all take onesize resource.Concrete management method is as follows:

The method of the resource of having distributed in the Bandwidth Management module is added up current ABIS interface is, business option when just having begun to set up according to each calling, as the coded format of using, type of call, and applied channel etc., determine that each calls out shared resource, and calculate occupied resource in the current ABIS interface with this.When call processing module during to the resource of Bandwidth Management module application ABIS interface, the Bandwidth Management module is that call processing module is distributed the resource in the ABIS interface according to assignable resource information in the current ABIS interface of preserving in the control and management piece.
The defective of said method is: if at the beginning of certain or certain several call setups, because data business volume is less, and there is not to be used for the SCH channel of transmitting data service, and in a period of time after call setup, because the increase of data business volume, set up the SCH channel again, then the shared resource of SCH channel is not added up within the scope that has taken by the Bandwidth Management module, that is to say that the actual resource that has taken does not conform to the occupied resource that the Bandwidth Management module is added up in the ABIS interface.The result that may cause is like this: the resource reality of certain bar PVC has been assigned with and has finished, but the call distribution that the Bandwidth Management module will be new is to this PVC, thereby makes the calling call drop of having set up.
In the prior art, no matter whether the resource to the ABIS interface manages, and all have following defective: speech business afterwards may tie up the bandwidth resources of the speech business that has connected, thereby the phenomenon of call drop occurs; And, because speech business and data service separately consider, when data service takies too much bandwidth resources, speech business can't be inserted, when speech business takies too much bandwidth resources, can't distribute resource bandwidth in the ABIS interface for data service.

Embodiment
For making technical scheme of the present invention clearer, the present invention is described in further detail again below in conjunction with specific embodiment.
The present invention is provided for managing the call processing module of BSC resource in advance in BSC, with the Bandwidth Management module that is used to manage the ABIS interface resource, this Bandwidth Management module also is referred to as ABIS interface bandwidth administration module, simultaneously in BSC, also be provided for storing the database of current all data messages of ABIS interface, i.e. the control and management piece.
Figure 3 shows that and use the schematic diagram that the ABIS interface resource is managed of the present invention.In call processing module 301 during to the resource of Bandwidth Management module 302 application ABIS interfaces, Bandwidth Management module 302 is according to the business information in the call processing module, at first determine type of service, and calculate the bandwidth that this service needed takies, the current bandwidth of distributing of query transmission corresponding service PVC from control and management piece 303 then, the current bandwidth of distributing bandwidth whether to take of judging again that this is used to transmit corresponding service PVC more than or equal to this service needed that has calculated, if, then Bandwidth Management module 302 distributes this to be used to transmit corresponding service PVC for call processing module 301, otherwise the bandwidth resources that Bandwidth Management module 302 refusals distribute ABIS to call processing module 301.After Bandwidth Management module 302 distributes PVC for call processing module 301, upgrade the respective resources information in the control and management piece 303.The specific implementation step is as follows:
At first, the PVC in the pre-configured ABIS interface of Bandwidth Management module makes it to be used to transmit the business of appointment.For example, three PVC are arranged in certain ABIS interface, its numbering is respectively a, b and c, the PVC of pre-configured a of being numbered of Bandwidth Management module and b only is used for transmitting voice service, the PVC that configuration is numbered c is used for transferring voice and data service, the SCH channel that is used for transmitting data service only allows to be configured in c, promptly if the resource of speech business application ABIS interface, then when the PVC resource that is numbered a and b is finished using, can this speech business of resource allocation of the PVC of c will be numbered, if the resource of the data service application ABIS interface that application SCH channel transmits, then can only be distributed among the c, and can not be distributed among a and the b.
Secondly, according to the call business type, will transmit the priority of the channel distribution of different business for more than one in advance, because every kind of channel can only be distributed on the PVC of appointment, therefore, the PVC of Bearer Channel has also just had corresponding priority level naturally.That is to say that the channel of a certain priority can be distributed on the PVC with it at the same level, also can be distributed on the PVC of low priority more.During resource scarcity in the ABIS interface, the channel of high priority can tie up the resource of low priority channel, and the channel of low priority can not tie up the resource of high priority channel, the channel that is high priority can be assigned on the PVC of low priority, and the channel of low priority can not be assigned on the PVC of high priority.In addition, the present invention also channel of lowest priority is set to removable type, and promptly the channel of the dismountable lowest priority of channel of high priority transmits the business of oneself.
In the present embodiment, set in advance the channel that is used for transmitting voice service and have limit priority, the SCH channel that is used for transmitting data service has lowest priority, and be removable type, correspondingly, be numbered a and b PVC have a limit priority, the PVC that is numbered c has lowest priority.Promptly when resource bandwidth was in short supply in the ABIS interface, the SCH channel resource that is used for transmitting data service among the c can be tied up by new speech business.
When call processing module during to the resource of Bandwidth Management module application ABIS, the Bandwidth Management module is according to the business information in the call processing module, judge when it is voice call service, then at first calculate the bandwidth that this speech business need take, the current bandwidth of distributing of query transmission speech business PVC from the control and management piece then, the current bandwidth of distributing bandwidth whether need take of judging again that this is used for transmitting voice service PVC more than or equal to this speech business that has calculated, if, then the Bandwidth Management module distributes this to be used for transmitting voice service PVC to call processing module, otherwise the Bandwidth Management module is judged the data service whether this PVC that is used for transferring voice and data service has application SCH channel to transmit, if do not have, then refuse to distribute the bandwidth resources of ABIS to call processing module, if have, after then removing the shared resource of this PVC SCH channel that is used for transferring voice and data service, distribute this to be used for the resource of transferring voice and data service PVC to call processing module.After the Bandwidth Management module is distributed PVC to call processing module, upgrade the respective resources information in the control and management piece.
For example, when the Bandwidth Management module is judged the interface resource of the speech business application ABIS that uses the Q8K encryption algorithm according to the business information in the call processing module, the Bandwidth Management module obtains the fixed-bandwidth Bv of speech coding algorithm according to the parameter in the call management module, according to system's convection current quantitative statistics, obtain the activity factor Av of speech channel, and this moment system efficiency of transmission Qv, and calculate this speech business speech channel occupied bandwidth Bc according to formula Bv * Av/Qv;
Then, the Bandwidth Management module is inquired about the current bandwidth of distributing that passes the PVC that is numbered a from the control and management piece, and judge that the current bandwidth of distributing is whether more than or equal to the bandwidth of the speech business speech channel that has calculated among the PVC be numbered a, if then the Bandwidth Management module PVC that will be numbered a distributes to call processing module;
Otherwise, the Bandwidth Management module is used said method again, judge that the current bandwidth of distributing is whether more than or equal to the bandwidth of the voice speech channel that has calculated among the PVC be numbered b, whether the current bandwidth of distributing of judging promptly from the control and management piece that inquiry passes the PVC that is numbered b is more than or equal to the bandwidth of the speech business speech channel that has calculated, if then the Bandwidth Management module PVC that will be numbered b distributes to call processing module;
Otherwise, whether Bandwidth Management module inquiry passes the PVC be numbered c from the control and management piece again the current bandwidth of distributing is more than or equal to the bandwidth of the speech business speech channel that has calculated, if, then the Bandwidth Management module PVC that will be numbered c distributes to call processing module, otherwise, the Bandwidth Management module is further judged the resource whether this PVC of SCH channel occupancy is arranged among the PVC that is numbered c, if do not have, then refuse to distribute the bandwidth resources of ABIS to call processing module, if have, after then removing the shared resource of this SCH channel, the PVC that is numbered c is distributed to call processing module.After the Bandwidth Management module is distributed PVC to call processing module, upgrade the respective resources information in the control and management piece.
When call processing module during to the resource of Bandwidth Management module application ABIS, the Bandwidth Management module is according to the business information in the call processing module, judge when it is data service, then at first calculate the bandwidth that this data service need take, the current bandwidth of distributing of the professional PVC of query transmission voice-and-data from the control and management piece then, the current bandwidth of distributing bandwidth whether need take of judging again that this is used for transferring voice and data service PVC more than or equal to this data service that has calculated, if, then the Bandwidth Management module distributes this to be used for transferring voice and the professional PVC of data mixing to call processing module, otherwise refusal distributes the bandwidth resources of ABIS to call processing module.After the Bandwidth Management module is distributed PVC to call processing module, upgrade the respective resources information in the control and management piece.
For example, when the Bandwidth Management module is judged the interface resource of data service application ABIS according to the business information in the call processing module, the Bandwidth Management module obtains the data rate Cv of this data service according to the parameter in the call management module, according to the efficiency of transmission Qv of channel utilization rate Dv with system's this moment, application of formula Cv * Av/Qv calculates this data service speech channel occupied bandwidth Bd again; Then, whether the Bandwidth Management module is inquired about pass the PVC be numbered c current and is distributed bandwidth more than or equal to the bandwidth of the speech business speech channel that has calculated from the control and management piece, if, then the Bandwidth Management module PVC that will be numbered c distributes to call processing module, otherwise refusal distributes the bandwidth resources of ABIS to call processing module.After the Bandwidth Management module is distributed PVC to call processing module, upgrade the respective resources information in the control and management piece.
In addition, because some channel, as the SCH channel, can distribute in the time of running, therefore after certain call business has connected, can be again to the shared resource of ABIS interface application SCH channel, similarly, the Bandwidth Management module is the current bandwidth of distributing of the PVC of inquiry respective priority from the control and management piece at first, whether the current bandwidth of distributing of PVC of judging this respective priority again is more than or equal to bandwidth to be applied for, if, then the Bandwidth Management module is distributed the resource of its required ABIS interface that is used for the SCH channel for this call business, and upgrade the respective resources information in the control and management piece immediately, with the real-time of assurance control and management piece internal information, otherwise the Bandwidth Management module is refused the resource to this call distribution ABIS.
When the business that has connected discharged shared channel resource, the Bandwidth Management module was upgraded the information of the current allowable resource of corresponding PVC in the control and management piece equally immediately, to guarantee the real-time of control and management piece internal information.
The method of upgrading certain bar PVC in the control and management piece is: when upgrading first, the value that the bandwidth B a that uses this PVC multiply by the bandwidth coordinating factor ψ of this PVC deducts the value of all occupied bandwidth among this PVC, if have only speech business among this PVC, i.e. application of formula Ba * ψ-∑ (Bc
i) calculate and to get final product, if existing speech business has data service again among this PVC, application of formula Ba * ψ-∑ (Bc then
i... Bd
j) calculate; In the non-process of upgrading first, use directly that this PVC is current to be distributed bandwidth to deduct shared bandwidth or add that the bandwidth that has discharged gets final product.In above-mentioned two formula, i and j represent the speech channel label in the multi-path call, Bc
iRepresent the bandwidth that i bar speech business speech channel need take, Bd
iRepresent the bandwidth that the needs of i bar data service speech channel take.Along with the development of CDMA technology, the channel for cdma system will be produced future is equally applicable to the present invention.
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.
