Description
Technical field
The present invention relates to communication technique field, specifically, relate to the method that operation layer improves resource request success rate and efficient.
Background technology
At present, continuous maturation along with group technology, develop based on Circuit-switched conventional telecommunication network towards broadband telecommunication net based on packet switching, concerning conventional telecommunication network, the call bearer that the user sets up is on the circuit that takies alone, as long as circuit is assigned to the calling that the user sets up, the service quality of this calling (QoS, Quality of Service) just can be guaranteed; But in the broadband telecommunication net, the call bearer that the user sets up is in the grouping passage of interim distribution, this calling only has been assigned with enough grouping passages (generally weighing as quantitative value with bandwidth), service quality just can be guaranteed, because being the grouping surface channel, one of characteristics of broadband packet net share to all users, the getable maximum bandwidth of user is that needs and operator are signatory simultaneously, when so obvious user initiates a calling, can not guarantee to be assigned to the bandwidth that enough foundation is called out, perhaps because the remaining grouping bandwidth chahnel of network is not enough, perhaps not enough because remain the bandwidth of usefulness not in user's available maximum bandwidth of contracting.
Therefore, in the broadband telecommunication net, must provide a cover mechanism to guarantee user's QoS service quality.
In order to realize QoS control, in the 3GPP normal structure, defined the framework of dynamic Q os policy control, specifically comprise 3 elements: gateway, strategy decisive function (Policy Decision Function, PDF) and application function (Application Function, AF), wherein gateway is inserting between IP Connection Service and the IP multi-media network; PDF carries out the policy decision point based on the local policy control of business, is responsible for the resource reservation/request for allocation of upper layer application is done response, also may initiatively report resource situation to operation layer because network resource status changes; The business demand that AF proposes according to the core key-course server in telecom operators or the service provider territory, initiate the request of IP bearing resource to PDF, IMS (IP multimedia service subsystem: IP Multimedia Core Network Subsystem) in the system in the definition of 3GPP normal structure, AF can be a P-CSCF (Proxy-Call Session Control Function entity: Proxy-Call Session ControlFunction), wherein, the interface between AF and the PDF is a Gq interface.More detailed description can be referring to the relevant criterion manuscript of 3GPP normal structure definition, can be referring to 3GPP TS 29.209 standard manuscripts as the definition of Gq interface.
Organize the NGN (next generation network: Next Generation Network) in the framework of subordinate's TISPAN (Telecommunications and InternetConverged Services and Protocols for Advanced Networking) definition at etsi standard, PDF is called SPDF (Service-basedPolicy Decision Function again, strategy decisive function based on business), its basic function is consistent with the PDF of 3GPP definition.Because the business demand in fixed network field and access bearer and mobile field be difference to some extent, in the TISPAN standard interface between AF and PDF/SPDF is called Gq ' interface, inherit and difference to show.Simultaneously, provided the resource admission control subsystem (RACS of responsible Qos resource reservation/distribution among the TISPAN, Resource Admission Control Subsystem) framework, to finish control, distribution, management function based on the bearer network resource of business demand, guarantee professional service quality, as shown in Figure 1.
Resource admission control subsystem comprises SPDF and two logical nes of Access-Resource and Admission Control Function, wherein, Access-Resource and Admission Control Function (Access-Resource and Admission Control Function, access-resource admission control function) provides admission control function, receive Qos resource (as bandwidth) request by Rq from SPDF, carry out access control according to information such as relevant access network resource and user's QoS are signatory, return the whether information of access of resource to SPDF by Rq.User's QoS CAMEL-Subscription-Information (QoS Profile) is stored among the NASS (Network Attachment Subsystem, Network Attachment Subsystem) as inserting signatory bandwidth etc., and Access-Resource and Admission Control Function can obtain by the E4 interface.
About RACS and two subsystems of NASS and Gq ' interface, the more detailed description of Rq and E4 interface can be referring to the relevant criterion manuscript of TISPAN definition, also can be referring to ITU-T normal structure relevant criterion manuscript to the definition of QoS framework in NGN, in the definition of ITU-T, RACS is called as RACF (Resource and Admission Control Function, the resource admission control function), NASS is called as NAAF (Network Access Attachment Function, the network insertion attached function), can be as Gq ' interface referring to the ETSI TS 183 017 standard manuscripts of TISPAN, Rq can be referring to ETSI ES 283 026 standard manuscripts of TISPAN etc.Easy for describing, will only write among the present invention with the name of TISPAN standard.
Describe based on above-mentioned background, when user's initiation session, apply for the needed QoS resource of session by AF to PDF/SPDF, PDF/SPDF or Access-Resource and Admission Control Function are handled this request, distribute Qos resource (as bandwidth) to the request of carrying transport layer, if the obtainable Internet resources of current this user can't satisfy the maximum resource of its requirement, then PDF/SPDF passes through Gq/Gq ' interface to AF feedback resources request failure, and AF will remove session.If but we consider such demand, when the obtainable Internet resources of user can't satisfy the maximum resource of its session requirement, if the user allows to degrade, and the current obtainable Internet resources of this user can satisfy the quality that degrades and allow, then should degrade, continue to guarantee that session is set up to session.Ask to initiate a video session such as the user, the maximum bandwidth of request is 10M, transmit bearing bed and find that the current obtainable maximum bandwidth of this user is 8M, the business that degrades if the user has contracted allows this video session also can set up (quality of video session decreases) under the 8M bandwidth, then transmits bearing bed and will allow this session to set up, obviously, above-mentioned prior art can't realize such business demand that degrades, and when the maximum bandwidth of conversation request can not satisfy, session will directly be discharged.
Therefore, be necessary prior art is improved to adapt to the needs of practical application.

Need to prove, more specifically, above-mentioned 5 expansions information that degrades can further be distinguished upstream bandwidth information and the downlink bandwidth information that degrades that degrades, can be defined as a pair of AVP parameter F allback-Information-UL AVP/Fallback-Information-DL AVP as Fallback-Information AVP, the bandwidth of the representing uplink and downlink respectively information that degrades, but because the upstream bandwidth of medium bandwidth often generally is identical with downlink bandwidth, not differentiating uplink and downlink that therefore also can be as indicated above carries out the degrade expansion of information of bandwidth.
To be stored in respectively with the information that degrades that the user contracts below in service application layer (customer service subscribed database), NASS and the PDF/SPDF or the Access-Resource and Admission Control Function of network the present invention will further be described.
A. the service application layer of information stores that degrade that the user contracts at network
When in user's the service application layer of information stores that degrade at network, need initiate to carry in the QoS resource request to PDF/SPDF by AF, promptly in Gq/Gq ' interface, carry, and AF will obtain this information that degrades, then need pass to AF by call control signalling by other network element that contains the customer service subscribed database in the service application layer of network, 3GPP/TISPAN/ITU-T adopts SIP to this call control signalling at present, therefore need carry this information that degrades in sip message.
If handling the degrade network element of demand of this user is PDF/SPDF, degrade information and pass through Gq/Gq ' interface and pass to PDF/SPDF that AF parses from the sip message that it is received that the user contracts.After PDF/SPDF obtains this information that degrades, according to the Internet resources behaviour in service, based on the local policy of operator rule and/or based on user's the signatory rule (as the QoS CAMEL-Subscription-Information) and the current network bandwidth etc. that used of user, whether the comprehensive maximum bandwidth demand of judging that the user asks can be met, if do not satisfy, but the bandwidth demand after simultaneously the current obtainable bandwidth of user satisfies the user and degrades, then permit the user and obtain bandwidth, and return the resource request success response to AF, the obtainable bandwidth information of user after wherein PDF/SPDF can will degrade by the Gq/Gq ' interface of expansion returns to AF, also can not return.
The network element of demand is an Access-Resource and Admission Control Function if process user degrades, and degrade information and pass through Gq/Gq ' interface and pass to PDF/SPDF that AF parses from the sip message that it is received that the user contracts passes to Access-Resource and Admission Control Function by PDF/SPDF by Rq again.After Access-Resource and Admission Control Function obtains this information that degrades, Access-Resource and Admission Control Function inserts according to the user that service quality CAMEL-Subscription-Information such as signatory maximum bandwidth and user are current have been used the network bandwidth to draw the user to insert the current obtainable bandwidth information of side, can not satisfy the maximum bandwidth demand of user's request, but satisfy the demand that degrades that the user contracts, then the user who returns after degrading to PDF/SPDF is inserting the current obtainable bandwidth information of side, PDF/SPDF is again according to the Internet resources user mode, after the comprehensive judgements such as local policy rule based on operator, permit the user and obtain bandwidth, and return the resource request success response to AF, the obtainable bandwidth information of user after PDF/SPDF can will degrade by the Gq/Gq ' interface of expansion returns to AF, also can not return.
B. the information stores that degrades that the user contracts is at NASS
If handling the degrade network element of demand of this user is PDF/SPDF, the information that degrades passes to Access-Resource and Admission Control Function by the E4 interface by NAS S, Access-Resource and Admission Control Function passes to PDF/SPDF again, the same, after PDF/SPDF obtains this information that degrades, according to the Internet resources behaviour in service, based on the local policy of operator rule and/or based on user's the signatory rule (as the QoS CAMEL-Subscription-Information) and the current network bandwidth etc. that used of user, whether the comprehensive maximum bandwidth demand of judging that the user asks can be met, if do not satisfy, but the bandwidth demand after simultaneously the current obtainable bandwidth of user satisfies the user and degrades, then permit the user and obtain bandwidth, and return the resource request success response to AF, the obtainable bandwidth information of user after wherein PDF/SPDF can will degrade by the Gq/Gq ' interface of expansion returns to AF, also can not return.
If handling the degrade network element of demand of this user is Access-Resource and Admission Control Function, the information that degrades passes to Access-Resource and Admission Control Function by the E4 interface by NASS, the same, Access-Resource and Admission Control Function inserts according to the user that service quality CAMEL-Subscription-Information such as signatory maximum bandwidth and user are current have been used the network bandwidth to draw the user to insert the current obtainable bandwidth information of side, can not satisfy the maximum bandwidth demand of user's request, but satisfy the demand that degrades that the user contracts, then return the back user that degrades and inserting the current obtainable bandwidth information of side to PDF/SPDF, PDF/SPDF is again according to the Internet resources user mode, after the comprehensive judgements such as local policy rule based on operator, permit the user and obtain bandwidth, and return the resource request success response to AF, the obtainable bandwidth information of user after PDF/SPDF can will degrade by the Gq/Gq ' interface of expansion returns to AF, also can not return.
C. the information stores that degrades that the user contracts is at PDF/SPDF or Access-Resource and Admission Control Function
At this moment, no longer need the aforesaid information that degrades of contracting by interface protocol expansion transmission user, and by PDF/SPDF according to the Internet resources behaviour in service, based on the local policy of operator rule and/or based on user's the signatory rule (as the QoS CAMEL-Subscription-Information) and the current network bandwidth etc. that used of user, whether the comprehensive maximum bandwidth demand of judging that the user asks can be met, if do not satisfy, but the bandwidth demand after simultaneously the current obtainable bandwidth of user satisfies the user and degrades, then authorized user can obtain bandwidth; Insert according to the user by Access-Resource and Admission Control Function perhaps that service quality CAMEL-Subscription-Information such as signatory maximum bandwidth and user are current have been used the network bandwidth to draw the user to insert the current obtainable bandwidth information of side, can not satisfy the maximum bandwidth demand of user's request, but satisfy the demand that degrades that the user contracts, then return the back user that degrades and inserting the current bandwidth information that obtains of side to PDF/SPDF, PDF/SPDF is again according to the Internet resources user mode, after the comprehensive judgements such as local policy rule based on operator, permit the user and obtain bandwidth, and return resource request success response PDF/SPDF to AF and can return to AF by the user obtainable bandwidth information of Gq/Gq ' interface after will degrading of expansion, can not return yet.
Next, the invention will be further described again with regard to a specific embodiment.
Suppose prerequisite earlier: the user initiates video session, request maximum bandwidth 10M, but the active user has only 8M in the obtainable bandwidth of access side; The user is in the signatory information that degrades of NASS, and particular content comprises: allow bandwidth to degrade to 8M at video, perhaps the user allows to degrade at video media and requires 80% of maximum bandwidth; Judgement that degrades and processing are carried out at Access-Resource and Admission Control Function.
Apply for the needed QoS resource of session by AF to PDF/SPDF, PDF/SPDF and Access-Resource and Admission Control Function are handled this request, distribute the Qos resource to the request of carrying transport layer, and the invention solves under such a case, it is the QoS resource requirement that the obtainable Internet resources of active user can not satisfy request, the user allows to degrade, then the information that degrades of contracting according to the user is handled, if the obtainable Internet resources of active user can satisfy the Qos resource requirement that the user degrades and allows, then return the request success response to AF, guarantee that session foundation continues by PDF/SPDF.
Concrete steps will be as shown in Figure 2:
1.AF resource to the needed maximum bandwidth 10M of PDF queued session;
2.PDF to the resource of Access-Resource and Admission Control Function request maximum bandwidth 10M, simultaneously, PDF also can be to carrying transport layer request resource information, and in this example, the Internet resources part of supposing the carrying transport layer can both satisfy the user resources demand, thus in Fig. 2 omission this part is mutual, chat bright earlier at this;
3.A-RACF to NASS request user contracting data;
4.NASS the E4 interface by expansion returns subscription data, comprises that the user inserts the signatory maximum bandwidth and the information etc. that degrades;
Judge that the present available resources of user have only 8M 5.A-RACF insert the current network bandwidth that used of service quality CAMEL-Subscription-Information such as signatory maximum bandwidth and user according to the user, according to the information that degrades that the user contracts, 8M can satisfy the bandwidth requirement after degrading;
Inserting the information that side can obtain bandwidth 8M 6.A-RACF return the back user that degrades, transmitting by AVP, as described later in the Rq expansion to PDF;
7.PDF,, determine finally that then it is 8M that the user can obtain bandwidth if current network resources also can be supported the 8M bandwidth according to judging from Access-Resource and Admission Control Function and the informix collected of carrying transport layer;
8.PDF passing through the AVP of Gq/Gq ' interface expansion can obtain bandwidth information with the end user and return to AF, the resource request success, degrade to 8M, session is set up and is continued, need to prove, passing through Gq/Gq ' the interface back user that will degrade and can obtain bandwidth information and return to AF, is not that the present invention is necessary, and PDF also can only return the resource request success response to AF and get final product.
