Embodiment
With embodiment the present invention is described in further detail with reference to the accompanying drawings below:
Referring to Fig. 2, Fig. 3, for realize collecting the digits, the overall situation of resource SRC such as voice shares, switch needs at first to provide that these overall situations collect the digits, voice special resource SRC, these global resources provide in the mode of veneer, can provide different resource types on the veneer, can determine the numbers of configuration according to what of resource requirement like this, during use according to collect the digits, the difference of voice resource type determines to use a certain resource time slot corresponding passage; Secondly the administration module CDP of global resource need be provided, and this module is used to finish the state-maintenance of global resource SRC, centralized management and distribution; SRC module and CDP all connect with each Switching Module SPC (Service Process, Business Processing) communication, and the SRC module is connected with the CDP communication.Under this mode, the collecting the digits of each module, voice resource can dispose seldom or at all need not configuration, and the SRC that only need keep the global configuration some gets final product.Need use at each SPC and to collect the digits or during special resource such as voice, at first can use the resource of this inside modules, if these resources of this inside modules can't be used for a certain reason, then SPC is unified to global resource administration module CDP application, distributes resource requirement by CDP according to its resource status that the SRC module reports.SPC receives after the resource allocation of CDP, and each module is networked to central switching network application, and central switching network couples together the shared use that can realize these special resources with resource time slot and user's time slot.Overload when directly mutual for fear of CDP and SRC module, system also comprises a central management unit (AMP), and AMP is used to carry out the forwarding that gathers of state, and the SRC module reports AMP with its resource state information, sends to CDP after being gathered by AMP.System also comprises the Back Administration Module that is connected with the AMP communication, and this module safeguards the state of chnnels of resources accordingly by maintenance command, such as inaccessible/open, isolate/go isolation, activation etc.These maintenance commands will change state of resources, and and then influence the distribution of resource.
The idiographic flow of this method is as follows:
(1), resource status reporting and transmitting
The status message of all resource veneers initiatively reports AMP, by being transmitted to resource management module CDP after the AMP aggregation process, the foundation when state of resources will be carried out resource allocation as CDP.Can reduce the load of resource management module like this.
(2), the application of resource and release
Switching Module SPC initiatively sends resource bid message to resource management module CDP when needs class resource, at first distribute the some or several free time in these resources, normal resource to give Switching Module SPC, initiatively discharge message related to resources after SPC finishes using to the CDP transmission by CDP.
(3), taking with information of resource reports
Switching Module SPC initiatively takies message, the corresponding relation of SRC recording channel and Switching Module to resource module SRC transmission chnnels of resources at the chnnels of resources that receives resource management module CDP distribution and after central switching network application is networked successfully; Central in addition switching network couples together resource time slot corresponding and user's time slot according to the networking request that Switching Module SPC sends, and after this this Switching Module just can normally use this resource, and SRC will initiatively report this Switching Module from the information that this passage receives.
(4) SPC uses resource, need send to global resource administration module CDP and discharge message related to resources, also need simultaneously to send release message so that really discharge this resource to SRC, tear net open to central switching network transmission and ask central net of dismounting to connect, the corresponding relation of removing passage and Switching Module behind the SRC reception release message.
(5), the maintenance of resource
Adopt Backend Administration Module the state of chnnels of resources to be safeguarded accordingly by maintenance command.
Use for these overall special resource SRC can be accessed comparatively uniformly simultaneously, adopt the mode of classification polling to carry out when CDP carries out resource allocation.In order to use flexibly, the channel resource on the veneer can be divided into several different unit, be configured to different resource types as required; Simultaneously the resource on veneer after all is conditional, according to the demand of resource what, possible configuration polylith resource veneer; So just the problem of a resource allocation policy is arranged.We select the mode of classification polling when resource allocation, and its strategy is as follows: CDP selects such normal unit at first successively when carrying out certain class resource allocation, then selects idle passage in this unit successively.For example: at first select first idle channel resource on first normal cell for the first time, distribute first idle channel resource on second normal cell when distributing this type of resource for the second time; And the like, if second passage on first normal cell all selected after one time in all unit again.Strategy above adopting can guarantee that substantially the resource on each unit evenly uses, and the unit of avoiding the front is too busy and the unit back is too idle.
Replacement scheme of the present invention is an example with the using method of digit receiver resource, its flow process as shown in Figure 4, Switching Module SPC is in the process of managing business, use the digit receiver resource if desired, then at first need to send the digit receiver solicitation message to the CDP plate, in the digit receiver resource of the overall situation, distribute one normally by the CDP plate, non-obturation, idle digit receiver, the CDP plate is after having assigned, take message to the transmission of the SRC of correspondence plate, after the SRC plate returns response message, the CDP plate returns assignment response message to this SPC plate again, notifies the numbering of the digit receiver that is distributed in this message, and notes the corresponding relation between digit receiver and SPC plate.After the SPC plate is received the response message that collects the digits of CDP plate, set up net and be connected between user's time slot that needs collect the digits and the digit receiver that is assigned to, this moment, this digit receiver just can begin to collect the digits.The SRC plate receive the CDP plate take message after, note the SPC plate module number that takies this digit receiver, during the later digit receiver number of receiving, directly send number message to the SPC of correspondence plate; After the SPC plate is received the message that collects the digits, carry out normal process.The SPC plate is in the process of managing business, if think when no longer needing to use the digit receiver resource, then send the digit receiver release message to the CDP plate, after the CDP plate is received the digit receiver release message, empty the corresponding relation between digit receiver and SPC plate, send release message to corresponding SRC plate, after the response of receiving the SRC plate, return digit receiver to the SPC plate and discharge response message.
The difference of this replacement scheme and former scheme is that take message and the release message to resource is to be sent or sent by CDP by Switching Module, it is to reduce the workload that CDP handles that former scheme adopts Switching Module to send to take the advantage with release message, makes it to be absorbed in maintenance and concentrated allocation manager with resource status.
Be understandable that, for those of ordinary skills, can be equal to replacement or change according to technical scheme of the present invention and inventive concept thereof, and all these changes or replacement all should belong to the protection range of the appended claim of the present invention.
