Hereinafter will describe the present invention with reference to the accompanying drawings and in conjunction with the embodiments in detail.Need to prove that under the situation of not conflicting, embodiment and the feature among the embodiment among the application can make up mutually.
Embodiment one
In embodiments of the present invention, for when Internet resources recover, QoS demand parameter value to the degraded business of QoS resource is upgraded, existing RACF is expanded, Fig. 2 is the structural representation according to the RACF of the embodiment of the invention one, and this RACF can comprise: acquisition module 10, determination module 20 and decision-making module 30.Wherein, acquisition module 10 is used to obtain the QoS demand parameter value of the degraded business of QoS resource before degradation, QoS demand parameter value and this business user information corresponding behind the degradation; Determination module 20 is used for determining the QoS demand parameter value that above-mentioned business can be upgraded to according to QoS demand parameter value behind current available resource, the degradation and the QoS demand parameter value before the degradation; Decision-making module 30, be used for the information according to current available resource, the above-mentioned QoS demand parameter value that can be upgraded to and with above-mentioned user profile decision-making resource and admission.
In actual applications, above-mentioned acquisition module 10 and decision-making module 30 can be realized by the PD-FE among Fig. 1, and determination module 20 can be united realization by PD-FE and TRC-FE, for example, PD-FE can obtain the current idling-resource of network by TRC-FE, thereby determines the QoS demand parameter value that degraded business can be upgraded to.
In correlation technique, when Internet resources are not enough, in order not stop business or session, RACF will demote to business or session QoS resource under the indication of SCF, but when resource is sufficient, do not recover the QoS resource of degraded business, thereby will cause utilization rate of network resource to descend, also reduce professional QoS simultaneously.And the above-mentioned RACF that the embodiment of the invention provides is when resource is sufficient, according to the QoS demand parameter value behind the QoS demand parameter value before the business degradation, the degradation and the current idling-resource of network, determine the QoS demand parameter value that this business can be upgraded to, according to this QoS demand parameter value business is carried out the resource and admission decision-making then, thereby can recover the part or all of QoS demand parameter value of this business, improve utilization rate of network resource effectively, improved user experience.
Preferably, as shown in Figure 3, RACF according to the embodiment of the invention can also comprise: memory module 40, be used to store the QoS demand parameter value of the degraded business of QoS resource before degradation, QoS demand parameter value and this business user information corresponding behind the degradation, then acquisition module 10 can obtain above-mentioned parameter from memory module 40.In actual applications, memory module 40 can be when Internet resources can not satisfy resource request that SCF initiates and SCF request RACF and carry out degraded operation, store the QoS demand parameter value of original (promptly before the degradation) of described user profile, institute's requested service and the QoS demand parameter value behind the degradation.Thereby can when being upgraded, degraded business make things convenient for acquisition module 10 to obtain relevant parameter.
Fig. 4 is the structural representation of another preferred RACF of the embodiment of the invention, as shown in Figure 4, this RACF can also comprise update module 50, be used under the identical situation of QoS demand parameter value before the above-mentioned QoS demand parameter value that can be upgraded to and the degradation QoS demand parameter value, demote preceding QoS demand parameter value and user profile behind the degraded above-mentioned professional degradation of the QoS resource of deletion memory module 40 storages; Under the QoS demand parameter value situation inequality before the above-mentioned QoS demand parameter value that can be upgraded to and the degradation (promptly only having carried out partly upgrading), the QoS demand parameter value behind the degradation that memory module 40 is stored is updated to the QoS demand parameter value that this can be upgraded to.Like this, under the situation of subsequent network resource abundance, can also further upgrade to this professional QoS demand parameter value.
Fig. 5 is the structural representation of the RACF of another preferred embodiment according to the present invention, as shown in Figure 5, this RACF can also comprise: notification module 60, be used for sending a notification message to SCF, carry the above-mentioned user profile and the successful indication parameter of upgrading in this notification message, be used to indicate SCF will successfully be upgraded to the QoS demand parameter value that above-mentioned business can be upgraded to this user profile corresponding service.In actual applications, this successful indication parameter of upgrading can comprise the whole upgrading success indication parameters and the successful indication parameter of partly upgrading, if the QoS demand parameter value that the business that determination module 20 is determined can be upgraded to is identical with the preceding QoS demand parameter value of demoting, then notification module 60 sends all successful indication parameters of upgrading, if before the QoS demand parameter value of QoS demand parameter value before degradation that the business that determination module 20 is determined can be upgraded to and the QoS demand parameter value behind the degradation, then notification module 60 sending parts divide upgrading successful indication parameter, thereby make SCF can know that related service is upgraded, the control that makes things convenient for SCF to be correlated with.
Fig. 6 is the flow chart according to the resource and admission decision-making technique of the embodiment of the invention one, and this method may further comprise the steps (step S602-step 606):
Step S602, RACF obtain QoS demand parameter value and this business user information corresponding behind the QoS demand parameter value of the degraded business of QoS resource before degradation, the degradation;
For example, before execution in step S602, SCF sends resource request message to RACF, (for example carry user profile in this resource request message, global ip address and/or user name etc.), QoS demand parameter (for example, bandwidth, type of service, the priority etc.) value of user institute requested service, the indication parameter of can demoting; If the current resource of network can not satisfy the resource request (being that resource is not enough) that SCF initiates, and SCF request RACF carries out degraded operation, then RACF can store the QoS demand parameter value of original (promptly before the degradation) of this user profile and institute's requested service, and admit decision-making according to the QoS demand parameter value behind current Resource Availability information, the degradation, preserve the QoS demand parameter value behind the degradation simultaneously.RACF carries out the Resource Availability inspection, if current available resource can satisfy the resource requirement of the original QoS demand parameter value of all or part of customer service, then RACF obtains the preceding QoS demand parameter value of this business degradation, QoS demand parameter value and this business user information corresponding behind the degradation.Perhaps, RACF also can be by the QoS demand parameter value before this business degradation is obtained in other network element inquiries, QoS demand parameter value and this business user information corresponding behind the degradation.
Step S604, RACF according to current available resource, the degradation after QoS demand parameter value and the degradation before QoS demand parameter value determine the QoS demand parameter value that this business can be upgraded to;
For example, RACF determines that current available resource can satisfy the resource requirement that the part or all of QoS demand parameter value of this business is upgraded, and then determines the QoS demand parameter value that this business can be upgraded to.
For example, current available resource can be this current summation that takies resource and current idling-resource, perhaps, also can be current idling-resource.
Step S606, RACF is according to the information of current available resource, the above-mentioned QoS demand parameter value that can be upgraded to and user profile decision-making resource and admission.
For example, if current available resource can satisfy the QoS demand parameter value before the above-mentioned professional degradation, then RACF determines the QoS demand parameter value before the above-mentioned QoS demand parameter value that can be upgraded to is degradation, after admitting decision-making, the described user profile that the RACF deletion is preserved when degradation, the QoS demand parameter value before the degradation and the QoS demand parameter value behind the degradation; If current available resource can only partly satisfy the QoS demand parameter value before the professional degradation, then RACF determines that the preceding QoS demand parameter value of above-mentioned QoS demand parameter value that can be upgraded to and degradation is different, the rank of this QoS demand parameter value be positioned at behind the degradation QoS demand parameter value with the degradation after QoS demand parameter value, for example, bandwidth demand value before the degradation is 5M, bandwidth demand value behind the degradation is 3M, and the bandwidth that current idling-resource can satisfy is 4M (promptly this business can be upgraded to the bandwidth of 4M), after then RACF carries out the resource and admission decision-making according to the QoS demand parameter value that can be upgraded to, the QoS demand parameter value behind the degradation is updated to the QoS demand parameter value that can be upgraded to.Thereby make follow-up can the continuation upgrade to this professional QoS demand parameter value.
Can know that in order to make SCF this professional QoS demand parameter value is upgraded, when RACF carries out the admittance decision-making, RACF sends a notification message to SCF, carry user profile and the successful indication parameter of upgrading in this notification message, indication SCF will successfully be upgraded to the above-mentioned QoS demand parameter value that can be upgraded to this user profile corresponding service, for example, if the part of only having upgraded QoS demand parameter value, then degraded customer service is partly upgraded successfully before this indication parameter indication, the QoS demand parameter value if all upgrade, then degraded customer service has returned to the preceding QoS demand parameter value of degradation before this indication parameter indication.
For example, after RACF admits decision-making, formulate new policing rule, and install to the transfer function entity this new strategy rule downloading, thereby can carry out professional according to the QoS demand parameter value after the upgrading.
In correlation technique, when Internet resources are not enough, in order not stop business or session, RACF will demote to business or session QoS resource under the indication of SCF, but when resource is sufficient, do not recover the QoS resource of degraded business, thereby will cause utilization rate of network resource to descend, also reduce professional QoS simultaneously.And the above-mentioned RACF that the embodiment of the invention provides is when resource is sufficient, according to the QoS demand parameter value behind the QoS demand parameter value before the business degradation, the degradation and the current idling-resource of network, determine the QoS demand parameter value that this business can be upgraded to, according to this QoS demand parameter value business is carried out the resource and admission decision-making then, thereby can recover the part or all of QoS demand parameter value of this business, improve utilization rate of network resource effectively, improved user experience.
